    Full Text Available Objective To investigate the clinical and pathological characteristics of sellar chondroid chordoma and discuss differential diagnosis of sellar chondroid chordoma with literature review. Methods The clinical manifestations of a patient with chondroid chordoma occurring in sellar area were stated. The morphological characteristics and immune phenotype were analyzed by using HE and immunohistochemical staining, and related literatures were reviewed. Results A 66-year-old male mainly presented with repeated hyponatremia. MRI revealed a well-circumscribed, round and space-occupying mass in sellar area. The tumor was removed under endoscope via the right nasal cavity. During the resection, the tumor could be seen locating in sellar region with solid, tough quality and clear boundaries. Histologically, part of the tumor showed the chondroid differentiation in classical chordoma. The immunohistochemistry of this tumor was positive for cytokeratin (CK, epithelial membrane antigen (EMA and S-100 protein (S-100, and Ki-67 labeling index was about 1%. The pathological diagnosis was sellar chondroid chordoma. During the follow-up period of 11 months, the patient was in good condition and no tumor recurrence was found. Conclusions Despite low incidence, chondroid chordoma usually develops in the midline regions with distinctive histological features and immunohistochemical phenotypes. In general, the prognosis is better than general type of chordoma, and the diagnosis should be differentiated from general types of chordoma and chondrosarcoma.doi:10.3969/j.issn.1672-6731.2014.02.007

    We describe a hemorrhagic chondroid chordoma involving the sella turcica with suprasellar extension. The CT and MRI appearances mimiked a hemorrhagic pituitary adenoma. Chondroid chordoma is a variant composed of elements of both chordoma and cartilaginous tissue. An uncommon bone neoplasm, located almost exclusively in the spheno-occipital region, it is usually not considered in the differential diagnosis of a tumor with acute hemorrhage in the sellar region. We discuss the clinical and radiological characteristics which may allow one to differentiate chondroid chordoma from other tumors of this area. (orig.) With 3 figs., 9 refs.

    Full Text Available Chordoma is a rare, slow-growing malignant tumor arising from notochordal remnants. A retrospective review of patient records at two major referral centers was undertaken to assess the incidence, location, and prognostic factors of metastatic disease from chordoma. 219 patients with chordoma (1962–2009 were identified. 39 patients (17.8% developed metastatic disease, most frequently to lung (>50%. Median survival from the time of initial diagnosis was 130.4 months for patients who developed metastatic disease and 159.3 months for those who did not (P=0.05. Metastatic disease was most common in the youngest patients (P=0.07, and it was 2.5 times more frequent among patients with local recurrence (26.3% than in those without (10.8% (P=0.003. Patient survival with metastatic disease was highly variable, and it was dependent on both the location of the tumor primary and the site of metastasis. Metastasis to distal bone was the most rapid to develop and had the worst prognosis.

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

    Chordoma is a locally invasive tumor of low metastatic potential. Only six cases of chordoma that metastasized to the brain are found in the English literature. Most of these lesions were clinically silent and all were associated with extraneural metastases. The authors report a case of symptomatic brain metastasis from a sacrococcygeal chordoma in the absence of other metastases. The incidence, sites, and factors predictive of chordoma metastasis are discussed.

    Objetive:To evaluate the efficacy of preoperative transcatheter arterial embolization in the treatment of sacral chordoma,and to explore the choice of embolization timing. Methods:32 patients underwent the posterior approach after TAE of the main arteries that supplied the sacral chordoma. Intraoperative bleeding amount of each patient was recorded and compared between-group differences at different operation times. Results: After embolization, 12 patients were received resection within 24 hours (group A),that of 10 cases between 24 ~ 48h (group B), of another 10 cases between 48~ 72h (group C). All of the 32 tumors were removed intact with intraoperative bleeding about (894±199)ml, without any shock or death,nor injuries on abdominal organs such as rectum and ureter. There was no statistical significance in tumor size among group A,B and C (P>0.05). Data gave statistical significance in intraoperative blood loss between group A and B (P<0.01) ,there was no statistical differences between group B and C (P>0.05), in spite of group B slightly less than group C. Conclusion: Preoperative TAE for excising the sacral tumor can significantly decrease intraoperative blood loss, make the surgical field clear,and facilitate the maximal removal of the sacral chordoma. It would be best to select the embolization timing within 24 hours before surgical operation.

    A patient with previously diagnosed sacrococcygeal chordoma presented with multiple skin nodules. Cytologic examination of an aspirate from one of these nodules showed syncytial clusters of hyperchromatic cells surrounded by extracellular mucin. The characteristic physaliphorous cells, although present in a biopsy of the primary sacrococcygeal tumor, were not observed in the aspirate or on histopathologic examination of three excised skin metastases. That chordoma metastases may lack physaliphorous cells should be recognized.

    A 75-year-old man presented with a rare case of chordoma in the sella turcica of the skull base. He had been treated for hypertension and chronic renal failure since 1990. Computed tomography detected a tumor in the sella turcica in 1994, but the patient had no clinical complaints and the serum pituitary hormone levels were normal. He died of disseminated intravascular coagulation, myocardial infarction, pulmonary infection, and multiple cerebral infarctions in 2000. At autopsy, the tumor in the sella turcica was 3.1 cm in greatest diameter and had compressed the pituitary gland posteriorly. Histological examination found oval cells and vacuolated short spindle-shaped cells which showed morphological changes similar to myxoma cells. The tumor was lobulated by narrow connective tissues. The tumor did not contain any cartilaginous tissue components, and was stained positively for epithelial membrane antigen but negatively for S-100 protein. The final diagnosis was chordoma. There was no association between the tumor and the cause of death.

    Object A chordoma is an indolent primary spinal tumor that has devastating effects on the patient’s life. These lesions are chemoresistant, resistant to conventional radiotherapy, and moderately sensitive to proton therapy; however, en bloc resection remains the preferred treatment for optimizing patient outcomes. While multiple small and largely retrospective studies have investigated the outcomes following en bloc resection of chordomas in the sacrum, there have been few large-scale studies on patients with chordomas of the mobile spine. The goal of this study was to review the outcomes of surgically treated patients with mobile spine chordomas at multiple international centers with respect to local recurrence and survival. This multiinstitutional retrospective study collected data between 1988 and 2012 about prognosis-predicting factors, including various clinical characteristics and surgical techniques for mobile spine chordoma. Tumors were classified according to the Enneking principles and analyzed in 2 treatment cohorts: Enneking-appropriate (EA) and Enneking-inappropriate (EI) cohorts. Patients were categorized as EA when the final pathological assessment of the margin matched the Enneking recommendation; otherwise, they were categorized as EI. Methods Descriptive statistics were used to summarize the data (Student t-test, chi-square, and Fisher exact tests). Recurrence and survival data were analyzed using Kaplan-Meier survival curves, log-rank tests, and multivariate Cox proportional hazard modeling. Results A total of 166 patients (55 female and 111 male patients) with mobile spine chordoma were included. The median patient follow-up was 2.6 years (range 1 day to 22.5 years). Fifty-eight (41%) patients were EA and 84 (59%) patients were EI. The type of biopsy (p < 0.001), spinal location (p = 0.018), and if the patient received adjuvant therapy (p < 0.001) were significantly different between the 2 cohorts. Overall, 58 (35%) patients developed local

    Purpose: To evaluate the clinical results of fractionated spot-scanning proton radiation therapy (PT) in 26 pediatric patients treated at Paul Scherrer Institute for chordoma (CH) or chondrosarcoma (CS) of the skull base or axial skeleton. Methods and Materials: Between June 2000 and June 2010, 19 CH and 7 CS patients with tumors originating from the skull base (17) and the axial skeleton (9) were treated with PT. Mean age at the time of PT was 13.2 years. The mean prescribed dose was 74 Gy (relative biological effectiveness [RBE]) for CH and 66 Gy (RBE) for CS, at a dose of 1.8-2.0 Gy (RBE) per fraction. Results: Mean follow-up was 46 months. Actuarial 5-year local control (LC) rates were 81% for CH and 80% for CS. Actuarial 5-year overall survival (OS) was 89% for CH and 75% for CS. Two CH patients had local failures: one is alive with evidence of disease, while the other patient succumbed to local recurrence in the surgical pathway. One CS patient died of local progression of the disease. No high-grade late toxicities were observed. Conclusions: Spot-scanning PT for pediatric CH and CS patients resulted in excellent clinical outcomes with acceptable rates of late toxicity. Longer follow-up time and larger cohort are needed to fully assess tumor control and late effects of treatment.

    To evaluate MR imaging of sacrococcygeal chordoma. Thirty patients (age range 22-80 years) underwent MR imaging for the diagnosis and preoperative evaluation of sacrococcygeal chordomas. Eight patients had follow-up MR examination after treatment. The MR images were performed with T1- and T2-weighted imaging, and gadolinium (Gd)-enhanced imaging. The MR images were analyzed for the signal intensity, enhancing pattern, tumor size, growth pattern of the soft tissue component, and tumor extension. T1-weighted images showed low signal masses with foci of high signal intensity in 73% of cases. Tumors enhanced in a variety of patterns after the administration of Gd. Soft tissue masses extending anteriorly were seen in all cases with posterior extension in 77% of cases. The posterior masses involved the surrounding muscles and extended toward the greater sciatic notch, appearing with pseudopodia (87%). Sacroiliac joints were involved in 23% of cases. Four lesions showed intraspinal extension and involvement of the posterior spinal muscles above the level of bony involvement. In 6 patients recurrent tumors were found at or around the surgical margin of the tumor 6 months to 5 years after resection of the sacral tumor. In two of the patients, nodular metastases to the pelvic bones and femur were found 1-4 years after initial examination. In conclusion, MR imaging is useful in the diagnosis and preoperative assessment of sacrococcygeal chordoma. Characteristic findings included sacral mass with heterogeneously high signal intensity with crisscrossing septa on long-repetition-time imaging, well-encapsulated pseudopodia-like or lobulated appearance, and gluteal muscle infiltration. Follow-up MR imaging is helpful to assess for recurrent or metastatic lesions of chordomas. (orig.)

    Full Text Available "Chondroid chordoma" is a controversial and confusing entity, a biphasic malignant neoplasm possessing elements of both chordoma and cartilaginous tissue. The annual incidence of chordoma is approximately one in one million. Chondroid chordoma is a subtype of chordoma possessing elements of both chordoma and cartilaginous tissue with better prognosis than classic (non chondroid chordomas. We have come across a case of Chondroid Chordoma in a 55 year old male. Our report features particularly a rare entity, chondroid chordoma, with an exceptional localization to the nasal septum. Chondroid Chordomas are likely to recur and hence diagnostically important to institute effective treatment

    Chordomas are rare tumours arising from notochordal remnants. Classical chordomas are generally extradural and, despite benign histopathology, they typically destroy the clivus and surrounding bone structures. Intradural lesions are extremely rare and less than thirty cases of intracranial, exclusively intradural chordomas have been reported so far. The intracranial, intradural but extranotochordal location of chordoma is extremely unique. The authors present a case of chordoma in intracranial location that clinically mimics lateral sphenoid wing meningioma. A previously healthy 39-year-old man was admitted to our Department because of optic disc oedema without neurological deficits. Neuroimaging studies showed a large, contrast-enhanced tumour in the right frontotemporal region that was thought to be a pterional meningioma. The patient underwent successful removal of the tumour. Histopathological study revealed a typical pattern of chordoma, confirmed by immunohistochemical findings. Because of the tumour location the differentiation between chordoma and chordoid meningioma ought to be considered. Such cases, including the present one, may lead to the conclusion that embryonic notochordal remnants may be lost in different places, even away from the neuroaxis.

    We report an unusual case of a chondroid chordoma of the sella turcica that mimicked the clinical and radiologic presentation of the more common pituitary adenoma. A 50-year-old man presented with bitemporal visual field deficits. Magnetic resonance imaging (MRI) detected a sellar mass that was suggestive of a pituitary adenoma. However, the intraoperative appearance of the mass was not consistent with an adenoma, and frozen-section pathology was obtained. Pathology identified the mass as a malignant lesion. Based on this finding, the mass was treated more aggressively. Chondroid chordomas are rare and slowly growing but locally aggressive tumors. The prognosis depends on the ability to totally resect the mass, so differentiating this tumor from a benign lesion is critical. An intrasellar chordoma can be confused clinically and radiologically with a pituitary adenoma. These two lesions are nearly identical on MRI, although T2-weighted imaging sometimes demonstrates higher intensity with a chondroid chordoma. Computed tomography may be helpful in demonstrating bony destruction by these lesions, as can the presence of intralesional calcifications. Intraoperative findings of bony invasion or a purple-red color may also lead the surgeon to suspect a diagnosis other than pituitary adenoma.

    The metastasis-associated phosphatase of regenerating liver-3 (PRL-3) plays multiple roles in progression of various human cancers; however, significance of its role during development has not been addressed. Here we cloned and characterized the expression pattern of zebrafish prl-3 transcript and showed that it is ubiquitiously expressed in the first 24 h of development with both maternal and zygotic expressions. The transcripts become progressively restricted to the notochord, vessels and the intestine by 96 h post-fertilization. Notably, overexpression of zebrafish Prl-3 (zPrl-3) and human PRL-3 induces notochord malformation in zebrafish. This phenotype resembles chordoma and is confirmed by associated misexpression of notochord-specific markers. Clinical significance of the PRL-3 in chordoma is strongly suggested by detection of PRL-3 antigen in clinical chordoma specimens. Collectively, our results uncovered that aberrant overexpression of PRL-3 could initiate chordoma in early development and suggest the use of PRL-3 could be used as a predictor and a therapeutic target for chordoma.

    Full Text Available Abstract Background Chordomas are rare neoplasms, arising from notochordal remnants in the midline skeletal axis, for which the current treatment is limited to surgery and radiotherapy. Recent reports suggest that receptor tyrosine kinases (RTK might be essential for the survival or proliferation of chordoma cells, providing a rationale for RTK targeted therapy. Nevertheless, the reported data are conflicting, most likely due to the assorted tumor specimens used for the studies and the heterogeneous methodological approaches. In the present study, we performed a comprehensive characterization of this rare entity using a wide range of assays in search for relevant therapeutic targets. Methods Histopathological features of 42 chordoma specimens, 21 primary and 21 advanced, were assessed by immunohistochemistry and fluorescent in situ hybridization (FISH using PDGFRB, CSF1R, and EGFR probes. Twenty-two of these cases, for which frozen material was available (nine primary and 13 advanced tumors, were selectively analyzed using the whole-genome 4.3 K TK-CGH-array, phospho-kinase antibody array or Western immunoblotting. The study was supplemented by direct sequencing of KIT, PDGFRB, CSF1R and EGFR. Results We demonstrated that EGFR is frequently and the most significantly activated RTK in chordomas. Furthermore, concurrent to EGFR activation, the tumors commonly reveal co-activation of alternative RTK. The consistent activation of AKT, the frequent loss of the tumor suppressor PTEN allele, the recurrent activation of upstream RTK and of downstream effectors like p70S6K and mTOR, all indicate the PI3K/AKT pathway as an important mediator of transformation in chordomas. Conclusions Given the complexity of the signaling in chordomas, combined treatment regimens targeting multiple RTK and downstream effectors are likely to be the most effective in these tumors. Personalized therapy with careful selection of the patients, based on the molecular profile of

Current evidence supports the role of maximal safe surgical resection. In addition to open skull-base approaches, the endoscopic endonasal approach to clival chordomas has been reported with favorable albeit early results. Adjuvant radiation is prescribed following complete resection, alternatively for gross residual disease or at the time of recurrence. The modalities of adjuvant radiation therapy reported vary widely and include proton-beam, carbon-ion, fractionated photon radiotherapy, and photon and gamma-knife radiosurgery. As of now, no direct comparison is available, and high-level evidence demonstrating superiority of one modality over another is lacking. While systemic therapies have yet to form part of any first-line therapy for chordomas, a number of targeted agents have been evaluated to date that inhibit specific molecules and their respective pathways known to be implicated in chordomas. These include EGFR (erlotinib, gefitinib, lapatinib, PDGFR (imatinib, mTOR (rapamycin, and VEGF (bevacizumab. This article provides an update of the current multimodality treatment of cranial base

    Full Text Available Chordoma is a rare tumor arising in the sacrum, clivus, or vertebrae. It is often not completely resectable and shows a high incidence of recurrence and progression with shortened patient survival and impaired quality of life. Chemotherapeutic options are limited to investigational therapies at present. Therefore, adjuvant therapy for control of tumor recurrence and progression is of great interest, especially in skull base lesions where complete tumor resection is often not possible because of the proximity of cranial nerves. To understand the extent of genetic instability and associated chromosomal and gene losses or gains in skull base chordoma, we undertook whole-genome single-nucleotide polymorphism microarray analysis of flash frozen surgical chordoma specimens, 21 from the clivus and 1 from C1 to C2 vertebrae. We confirm the presence of a deletion at 9p involving CDKN2A, CDKN2B, and MTAP but at a much lower rate (22% than previously reported for sacral chordoma. At a similar frequency (21%, we found aneuploidy of chromosome 3. Tissue microarray immunohistochemistry demonstrated absent or reduced fragile histidine triad (FHIT protein expression in 98% of sacral chordomas and 67%of skull base chordomas. Our data suggest that chromosome 3 aneuploidy and epigenetic regulation of FHIT contribute to loss of the FHIT tumor suppressor in chordoma. The finding that FHIT is lost in a majority of chordomas provides new insight into chordoma pathogenesis and points to a potential new therapeutic target for this challenging neoplasm.

    A retrospectively analysis of CT and MR findings was performed in five patients with histologically proved chordoma including one with chondroid chordoma. All tumors were mostly isodense to gray matter on unenhanced CT, and the single intensities were iso or low and high on T1 and T2-weighted MR images, respectively. The tumors had an increase in their density on enhanced CT and MR in four patients, but a chondroid chordoma was poorly enhanced after injection of contrast medicum on CT. Four tumors contained calcifications in CT images and two lesionsshowed hemorrhage in MR images. Cavenous sinus was involved in all patients, and brain stem and basilar artery were compressed by the tumors in three cases. Pituitary gland was only displaced upward in three patients. Clivus was destroyed in all cases, and sella turcica and sphenoid bone were involved in three patients. CT is better than MR in demonstrating calcifications and bone destruction. In defining the extension of tumor, MR appears to be superior to CT in evaluation of the relationship between the tumor and the surrounding structures.

    Chordomas are midline tumors that arise from embryonic remnants of the notochord and are considered to be malignant tumors because of their tendency to invade and destroy the involved bone. Cases of intradural chordomas without bone involvement have been rarely described with a predilection for prepontine location. The absence of bony invasion renders the complete excision of these tumors more feasible and is related to their better prognosis in comparison to conventional chordomas. Herein we report the first intradural chordoma arising in the Meckel's cave. The intradural location of the lesion, outside midline structures, in the absence of bone infiltration, made the differential diagnosis versus other meningeal lesions such as chordoid meningioma challenging. The intense and strong immunohistochemical expression of pan-cytokeratins, S100, cytokeratin-19 and of the notochordal marker brachyury allowed differential diagnosis toward other tumors showing chordoid morphology. The expression of brachyury, which had not been previously analyzed in intradural chordoma, definitely links the histogenesis of this neoplasia to the notochord, similar to that of conventional chordoma. We also show that, different from conventional chordoma, intradural chordoma does not express the metallo-proteinases (MMPs) -2 and -9, which may account for its indolent biological behavior.

    Chordoma is a rare malignant bone tumour with a poor prognosis and limited therapeutic options. We undertook a focused compound screen (FCS) against 1097 compounds on three well-characterized chordoma cell lines; 154 compounds were selected from the single concentration screen (1 µm), based on their growth-inhibitory effect. Their half-maximal effective concentration (EC50 ) values were determined in chordoma cells and normal fibroblasts. Twenty-seven of these compounds displayed chordoma selective cell kill and 21/27 (78%) were found to be EGFR/ERBB family inhibitors. EGFR inhibitors in clinical development were then studied on an extended cell line panel of seven chordoma cell lines, four of which were sensitive to EGFR inhibition. Sapitinib (AstraZeneca) emerged as the lead compound, followed by gefitinib (AstraZeneca) and erlotinib (Roche/Genentech). The compounds were shown to induce apoptosis in the sensitive cell lines and suppressed phospho-EGFR and its downstream pathways in a dose-dependent manner. Analysis of substituent patterns suggested that EGFR-inhibitors with small aniline substituents in the 4-position of the quinazoline ring were more effective than inhibitors with large substituents in that position. Sapitinib showed significantly reduced tumour growth in two xenograft mouse models (U-CH1 xenograft and a patient-derived xenograft, SF8894). One of the resistant cell lines (U-CH2) was shown to express high levels of phospho-MET, a known bypass signalling pathway to EGFR. Neither amplifications (EGFR, ERBB2, MET) nor mutations in EGFR, ERBB2, ERBB4, PIK3CA, BRAF, NRAS, KRAS, PTEN, MET or other cancer gene hotspots were detected in the cell lines. Our findings are consistent with the reported (p-)EGFR expression in the majority of clinical samples, and provide evidence for exploring the efficacy of EGFR inhibitors in the treatment of patients with chordoma and studying possible resistance mechanisms to these compounds in vitro and in vivo. © 2016

    Full Text Available An unusual case of entirely infrasellar craniopharyngioma mimicking a clival chordoma is described. Only 22 cases of craniopharyngioma with nasopharyngeal extension have been reported in the literature. Of the reported cases, most were primarily intracranial with secondary downward extension; only two were thought to originate from an infrasellar location. The present case is another example of an entirely infrasellar craniopharyngioma, with extensive clival destruction, mimicking a clival chordoma. Relevant literature on the subject is reviewed.

    Full Text Available Abstract Introduction Chordomas are rare tumors of the skeletal system that arise from an intra-osseous benign precursor of notochordal cells. They are mainly locally aggressive. However, metastases to other sites, including the humeri, resulting in pathological fractures have been reported. We report the case of a patient with a metastatic chordoma that produced a pathologic fracture of the humerus. Case presentation We report the case of a 60-year-old Iranian woman who presented with a fracture of her right humerus following a minor trauma. She had a history of a sacrococcygeal chordoma. Histological and immunohistochemical studies of the fracture site suggested the diagnosis of a chordoma. Conclusions Chordoma is a rare tumor and rarely metastasizes, but it should be considered in the differential diagnosis of epithelioid bone tumors. The only current effective treatment for this type of tumor is carbon ion therapy. There is currently no effective medical therapy available for advanced chordoma, and this type of tumor is not very responsive to radiotherapy.

    Full Text Available Objective: Chordoma is a rare tumor with an unpredictable behaviour, and can display malignant behavior because of its tendency to local invasion and recurrence. We searched the prognostic value of histologic features, growth pattern, localization and Ki-67 proliferation index to predict disease-free survival.Material and Method: Twenty-nine cases diagnosed in a single center were included in the study and evaluated with their 81 surgical specimens, (29 primary tumors, 47 recurrent lesions and five metastatic foci regarding their matrix formation (myxoid, chondroid, cellular features, (pleomorphism, necrosis, inflammatory infiltration, patterns of proliferation (solid, trabecular, mixed and Ki-67 proliferation indices.Results: Eleven of the cases were females (37.9% while 18 of them were males (62.1% with a mean age of 54.1±14.6 (ranged between age 23-78 years. Thirty-eight percent of tumors were located in sacrococcigeal region followed by skull base and vertebrae (31% for both. Skull base chordomas which occured in younger patients (p=0.048 showed more trabecular pattern (p=0.04, chondroid matrix (p=0.063, lower Ki-67 (p=0.146 and longer disease-free survival (p=0.021. In contrast, tumors located in vertebrae, showed more “atypical” morphology with solid pattern, nuclear pleomorphism and dedifferentiation, higher Ki-67 indices and shorter disease-free survivals (p=0.021. Sacral tumors were the “intermediate group” which occurred in older patients, and demonstrated average Ki-67 proliferation indices and disease-free survivals.Conclusion: Vertebral localization, probably in relation with both histologic features and failure of surgery, appeared as a significant risk factor for recurrence and Ki-67 proliferation index retained its potential to predict disease-free survival.

    Conclusion: There are few previous reports of petroclival chordomas causing acute intracranial hemorrhage. To the authors′ knowledge, this is the first case of a petroclival chordoma presenting as acute intracranial hemorrhage in a pediatric patient. Although uncommon, it is important to consider chordoma when evaluating a patient of any age presenting with a hemorrhagic lesion of the clivus.

    We present an unusual case of a chordoma presenting as an extradural spinal tumour with extension through an expanded intervertebral foramen to form a large paraspinal mass. The magnetic resonance imaging appearances closely mimicked a neurofibroma; however, pre-operative biopsy confirmed the diagnosis of chordoma. This is, to our knowledge, the tenth reported case of chordoma presenting as a mass expanding the intervertebral foramen. Thus, while it is a rare form of chordoma, it can lead to a recognised radiological pitfall. Making the distinction from neurofibroma before surgery is essential, as radical dissection of chordoma is required to reduce the risk of local recurrence. (orig.)

    Purpose: To investigate [18F]-fluoromisonidazole positron emission tomography/computed tomography (FMISO-PET/CT) detection of targetable hypoxic subvolumes (HSVs) in chordoma of the mobile or sacrococcygeal spine. Methods and Materials: A prospective, pilot study of 20 patients with primary or locally recurrent chordoma of the mobile or sacrococcygeal spine treated with proton or combined proton/photon radiation therapy (RT) with or without surgery was completed. The FMISO-PET/CT was performed before RT and after 19.8-34.2 GyRBE (relative biologic effectiveness). Gross tumor volumes were delineated and HSVs defined including voxels with standardized uptake values ≥1.4 times the muscle mean. Clinical characteristics and treatments received were compared between patients with and without HSVs. Results: The FMISO-PET/CT detected HSVs in 12 of 20 patients (60%). Baseline and interval HSV spatial concordance varied (0%-94%). Eight HSVs were sufficiently large (≥5 cm{sup 3}) to potentially allow an intensity modulated proton therapy boost. Patients with HSVs had significantly larger gross tumor volumes (median 410.0 cm{sup 3} vs 63.4 cm{sup 3}; P=.02) and were significantly more likely to have stage T2 tumors (5 of 12 vs 0 of 8; P=.04). After a median follow-up of 1.8 years (range, 0.2-4.4 years), a local recurrence has yet to be observed. Three patients developed metastatic disease, 2 with HSVs. Conclusions: Detection of targetable HSVs by FMISO-PET/CT within patients undergoing RT with or without surgery for treatment of chordoma of the mobile and sacrococcygeal spine is feasible. The study's inability to attribute interval HSV changes to treatment, rapidly changing hypoxic physiology, or imaging inconsistencies is a limitation. Further study of double-baseline FMISO-PET/CT and hypoxia-directed RT dose escalation, particularly in patients at high risk for local recurrence, is warranted.

    2007-01-01

    Caroli's syndrome is characterized by multiple segmental cystic or saccular dilatations of intrahepatic bile ducts associated with congenital hepatic fibrosis. The clinical features of this syndrome reflect both the characteristics of congenital hepatic fibrosis such as portal hypertension and that of Caroli's disease named as recurrent cholangitis and cholelithiasis. The diagnosis depends on both histology and imaging methods which can show the communication between the sacculi and the bile ducts. Treatment consists of symptomatic treatment of cholangitis attacks by antibiotics, some endoscopic,radiological and surgical drainage procedures and surgery. Liver transplantation seems the ultimate treatment for this disease. Prognosis is fairly good unless recurrent cholangitis and renal failure develops.

    Full Text Available Abstract Background Chordoma, a rare cancer, is usually treated with surgery and/or radiation. However, very limited characterizations of chordoma cells are available due to a minimal availability (only two lines validated by now and the extremely long doubling time. In order to overcome this situation, we successfully derived a cell line with a shorter doubling time from the first validated chordoma line U-CH1 and obtained invaluable cell biological data. Method After isolating a subpopulation of U-CH1 cells with a short doubling time (U-CH1-N, cell growth, cell cycle distribution, DNA content, chromosome number, p53 status, and cell survival were examined after exposure to X-rays, heavy ions, camptothecin, mitomycin C, cisplatin and bleocin. These data were compared with those of HeLa (cervical cancer and U87-MG (glioblastoma cells. Results The cell doubling times for HeLa, U87-MG and U-CH1-N were approximately 18 h, 24 h and 3 days respectively. Heavy ion irradiation resulted in more efficient cell killing than x-rays in all three cell lines. Relative biological effectiveness (RBE at 10% survival for U-CH1-N was about 2.45 for 70 keV/μm carbon and 3.86 for 200 keV/μm iron ions. Of the four chemicals, bleocin showed the most marked cytotoxic effect on U-CH1-N. Conclusion Our data provide the first comprehensive cellular characterization using cells of chordoma origin and furnish the biological basis for successful clinical results of chordoma treatment by heavy ions.

    2016-01-01

    Full Text Available Background: Resection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high. Use of computer navigation may allow optimal preoperative planning and improve precision in tumor resection. The purpose of this study was to evaluate the safety and feasibility of computer navigation-aided resection of sacral chordomas. Methods: Between 2007 and 2013, a total of 26 patients with sacral chordoma underwent computer navigation-aided surgery were included and followed for a minimum of 18 months. There were 21 primary cases and 5 recurrent cases, with a mean age of 55.8 years old (range: 35-84 years old. Tumors were located above the level of the S3 neural foramen in 23 patients and below the level of the S3 neural foramen in 3 patients. Three-dimensional images were reconstructed with a computed tomography-based navigation system combined with the magnetic resonance images using the navigation software. Tumors were resected via a posterior approach assisted by the computer navigation. Mean follow-up was 38.6 months (range: 18-84 months. Results: Mean operative time was 307 min. Mean intraoperative blood loss was 3065 ml. For computer navigation, the mean registration deviation during surgery was 1.7 mm. There were 18 wide resections, 4 marginal resections, and 4 intralesional resections. All patients were alive at the final follow-up, with 2 (7.7% exhibiting tumor recurrence. The other 24 patients were tumor-free. The mean Musculoskeletal Tumor Society Score was 27.3 (range: 19-30. Conclusions: Computer-assisted navigation can be safely applied to the resection of the sacral chordomas, allowing execution of preoperative plans, and achieving good oncological outcomes. Nevertheless, this needs to be accomplished by surgeons with adequate experience and skill.

    Two cases are reported of a newly described intraosseous entity of vertebral bodies deemed ''giant notochordal hamartoma of intraosseous origin''. This entity is commonly mistaken for chordoma and must be distinguished from it as the consequences of misinterpretation may be serious. The clinical, radiological and histologic criteria that can be used to distinguish these two entities are emphasized. Included is a proposed pathogenesis for this lesion, its probable notochordal origin, and a review of other probable cases. (orig.)

    Eighteen patients with a proven histologic diagnosis of chordoma were treated between 1949 and 1982. Four patients received only surgery, 4 patients only radiation therapy, and 10 patients received surgery and postoperative radiation therapy to a varying dose. The results suggest that a higher radiation dose gives longer recurrence-free survival, and that the best long term results can be achieved by combining surgery - as radically as possible - with radiation therapy to a dose level of 60 to 65 Gy. In view of the number of marginal recurrences (2 out of the 14 patients who received radiation therapy), the importance of choosing the right treatment volume is stressed.

    2014-03-16

    Chordomas are malignant tumors arising from notochordal remnants. They are the most frequent tumors of the spine after plasmacytomas. Only 6% of chordomas are localized to the cervical level. In young patients, chordomas are rare and unpredictable. Despite this, the treatment of choice remains the total resection, as much as possible, followed by proton beam radiation. This case was managed using a precarotid and retrocarotid approach at the same time. The tumor was completely resected with the edges free from disease. The cervical spine was stabilized with an anterior plating C2-C4. Eighteen months after surgery the patient is still free from illness. Multilevel oblique corpectomies are an available and safe option for the treatment of upper cervical chordomas.

    Chordomas are rare malignant bone tumours with a predilection for the axial skeleton, especially the sacrum and skull base. Median survival in patients with metastatic disease is usually dismal. Treatment is challenging due to the propensity for local recurrence, metastatic disease as well as lack of clear consensus regarding the optimal management. Our case report highlights two cases of sacral chordoma with locally recurrent and widespread metastatic disease, stable on molecular targeted therapy. PMID:26180502

    Purpose: To report the results in patients reirradiated with proton therapy for recurrent or progressive chordoma, with or without salvage surgery. Methods and Materials: A retrospective review of 16 consecutive patients treated from 2005 to 2012 was performed. All patients had received at least 1 prior course of radiation therapy to the same area, and all but 1 patient had at least 1 surgical resection for disease before receiving reirradiation. At the time of recurrence or progression, half of the patients underwent additional salvage surgery before receiving reirradiation. The median prior dose of radiation was 75.2 Gy (range, 40-79.2 Gy). Six patients had received prior proton therapy, and the remainder had received photon radiation. The median gross tumor volume at the time of reirradiation was 71 cm{sup 3} (range, 0-701 cm{sup 3}). Reirradiation occurred at a median interval of 37 months after prior radiation (range, 12-129 months), and the median dose of reirradiation was 75.6 Gy (relative biological effectiveness [RBE]) (range. 71.2-79.2 Gy [RBE]), given in standard daily fractionation (n=14) or hyperfractionation (n=2). Results: The median follow-up time was 23 months (range, 6-63 months); it was 26 months in patients alive at the last follow-up visit (range, 12-63 months). The 2-year estimate for local control was 85%, overall survival 80%, chordoma-specific survival 88%, and development of distant metastases 20%. Four patients have had local progression: 3 in-field and 1 marginal. Late toxicity included grade 3 bitemporal lobe radionecrosis in 1 patient that improved with hyperbaric oxygen, a grade 4 cerebrospinal fluid leak with meningitis in 1 patient, and a grade 4 ischemic brainstem stroke (out of radiation field) in 1 patient, with subsequent neurologic recovery. Conclusions: Full-dose proton reirradiation provided encouraging initial disease control and overall survival for patients with recurrent or progressive chordoma, although additional

    Recent evidence suggests that the expression of brachyury is necessary for chordoma growth. However, the mechanism associated with brachyury-regulated cell growth is poorly understood. Fibroblast growth factor (FGF), a regulator of brachyury expression in normal tissue, may also play an important role in chordoma pathophysiology. Using a panel of chordoma cell lines, we explored the role of FGF signaling and brachyury in cell growth and survival. Western blots showed that all chordoma cell lines expressed fibroblast growth factor receptor 2 (FGFR2), FGFR3, mitogen-activated protein kinase kinase (MEK) and extracellular signal-regulated kinase (ERK), whereas no cell lines expressed FGFR1 and FGFR4. Results of enzyme-linked immunosorbent assay indicated that chordoma cells produced FGF2. Neutralization of FGF2 inhibited MEK/ERK phosphorylation, decreased brachyury expression and induced apoptosis while reducing cell growth. Activation of the FGFR/MEK/ERK/brachyury pathway by FGF2-initiated phosphorylation of FGFR substrate 2 (FRS2)-α (Tyr196) prevented apoptosis while promoting cell growth and epithelial-mesenchymal transition (EMT). Immunofluorescence staining showed that FGF2 promoted the translocation of phosphorylated ERK to the nucleus and increased brachyury expression. The selective inhibition of FGFR, MEK and ERK phosphorylation by PD173074, PD0325901 and PD184352, respectively, decreased brachyury expression, induced apoptosis, and inhibited cell growth and EMT. Moreover, knockdown of brachyury by small hairpin RNA reduced FGF2 secretion, inhibited FGFR/MEK/ERK phosphorylation and blocked the effects of FGF2 on cell growth, apoptosis and EMT. Those findings highlight that FGFR/MEK/ERK/brachyury pathway coordinately regulates chordoma cell growth and survival and may represent a novel chemotherapeutic target for chordoma.

    The radiologist plays a crucial role in identifying and narrowing the differential diagnosis of intracranial infections. A thorough understanding of the intracranial compartment anatomy and characteristic imaging findings of specific pathogens, as well incorporation of the clinical information, is essential to establish correct diagnosis. Specific types of infections have certain propensities for different anatomical regions within the brain. In addition, the imaging findings must be placed in the context of the clinical setting, particularly in immunocompromised and human immunodeficiency virus (HIV)-positive patients. This paper describes and depicts infections within the different compartments of the brain. Pathology-proven infectious cases are presented in both immunocompetent and immunocompromised patients, with a discussion of the characteristic findings of each pathogen. Magnetic resonance spectroscopy (MRS) characteristics for several infections are also discussed.

    AIM: To investigate the clinical characteristics of fulminant hepatitis in pregnancy.METHODS: We compared and analyzed the etiology,clinical characteristics, and laboratory examinations of 25 cases of fulminant hepatitis in pregnancy and 30 cases of fulminant hepatitis not in pregnancy.RESULTS: HBV infection and chronic fulminant hepatitis were most common both in the pregnant and in the non-pregnant groups. Jaundice, digestive tract symptoms,increase of bilirubin and thrombinogen activity were the main manifestations. The incidence of hepatic encephalopathy (HE) and hepato-renal syndrome (HRS) was significantly different between the two groups. The incidence of preterm labor, dead fetus and neonatal asphyxia was high.CONCLUSION: Fulminant hepatitis is likely to occur in late pregnancy with more severe complications, which significantly influences maternity, perinatal fetus, and newborn.

    New antiepileptic drugs (AEDs) that have been used in many other countries for more than 10 years have only recently became available for use in Japan. Gabapentin, topiramate, lamotrigine and levetiracetam were licensed for use in Japan between 2006 and 2010. Stiripentol for Dravet syndrome and rufinamide for Lennox-Gastaut syndrome were also approved in 2012 and 2013 as orphan drugs. Clinical trials of other new AEDs such as oxcarbazepine, vigabatrin, lacosamide, and perampanel are in progress. In this review, the general characteristics of the new AEDs are discussed with regards to their effectiveness, tolerability, drug interaction, safety and mechanisms of action. The effectiveness, of the new AEDs compared with established AEDs is also discussed. Clinical applications of the new AEDs, focusing on gabapentin, topiramate, lamotrigine and levetiracetam are also discussed based on our domestic experience as well as overseas reports.

    Acromegaly and pituitary gigantism are very rare conditions resulting from excessive secretion of growth hormone (GH), usually by a pituitary adenoma. Pituitary gigantism occurs when GH excess overlaps with the period of rapid linear growth during childhood and adolescence. Until recently, its etiology and clinical characteristics have been poorly understood. Genetic and genomic causes have been identified in recent years that explain about half of cases of pituitary gigantism. We describe these recent discoveries and focus on some important settings in which gigantism can occur, including familial isolated pituitary adenomas (FIPA) and the newly described X-linked acrogigantism (X-LAG) syndrome.

    Objective To analyze the clinic characteristics of varicella zoster myocarditis and to determine the diagnostic value of serum cardiac troponin I (cTnI ) on the disease. Methods Information of 58 hospitalized patients with varicella zoster was collected, and the incidence of varicella zoster myocarditis and clinic characteristics (ECG, cTnI, age and sex distribution, etc. ) were analyzed respectively. Results It was found that 36.2% of the patients developed myocarditis. The old and female persons were much more susceptible to varicella zoster myocarditis. All patients had responsive ECG manifestations, and the abnormal ST-T changes were more common than other ECG abnormalities. CTnI remained higher than normal and had significant diagnostic value. Most of the patients had good prognosis, only a few patients lasted a long time and even progressed into cardiomyopathy. Nearly all the patients came to see dermatologists when they felt ill initially. That would lead to more misdiagnosis. Conclusion Infection of varicella zoster can complicate myocarditis, we must pay more attention to the patients who suffer from varicella zoster especially in the aged and female; cTnI is an important and effective index for diagnosis of varicella zoster myocarditis.

    Full Text Available CONTEXT: During the last 12 years we have observed an increase in the frequency of Sydenham's chorea in our country. We have observed that some of our patients have presented recurrence of the chorea despite regular treatment with benzathine penicillin. OBJECTIVE: The aim of our study was to evaluate clinical and evolutive characteristics of Sydenham's chorea in a group of patients followed in our Pediatric Rheumatology Unit. TYPE OF STUDY: Retrospective study. SETTING: Section of Pediatric Rheumatology - Discipline of Allergy, Clinical Immunology and Rheumatology - Department of Pediatrics - UNIFESP - EPM. PARTICIPANTS: Two hundred and ninety patients with rheumatic fever followed between 1986 and 1999. METHODS: We reviewed the records of 290 patients with rheumatic fever followed between 1986 and 1999. All patients were diagnosed according to the revised Jones criteria (1992. We included 86 patients that presented Sydenham's chorea as one of the major criteria (one or more attacks and evaluated their clinical and evolutive characteristics as well the treatment. RESULTS: Fifty-five patients were girls and 31 were boys. The mean age at onset was 9.7 years and mean follow-up period was 3.6 years. The 86 Sydenham's chorea patients presented 110 attacks of chorea. We observed isolated chorea in 35% of the patients, and 25 (29% presented one or more recurrences. We included only 17 of the 25 patients for further analysis, with a total of 22 recurrences of which 14 were attacks of chorea, because it was not possible to precisely detect the interval between attacks in the other patients. The approximate interval between the attacks ranged from 4 to 96 months. In 71% of the patients there was no failure in the secondary prophylaxis with benzathine penicillin, which was performed every 3 weeks. CONCLUSION: Despite the regular use of secondary benzathine penicillin prophylaxis, children with rheumatic fever have a high risk of Sydenham's chorea

    Chordomas are rare tumors which originate from the remnants of the notochord.These tumors are locally aggressive and have a predilection for the ends of the axial skeleton.An important prerequisite for optimal management of these tumors is a correct preoperative diagnosis.The present case is the first report of the use of endoscopic ultrasound to obtain transrectal fine needle aspiration biopsy of a presacral chordoma.A review of the prior computer tomography (CT) scans allowed us to calculate the tumor volume doubling time (18.3 mo).Transrectal biopsy of chordomas is controversial,however we believe that such concerns are not justified.

    Background and Objectives Marfan syndrome (MFS) is a connective tissue disorder with autosomal dominant inheritance and a highly variable clinical spectrum. However, there are limited data available on the clinical features of Korean patients with MFS. The aim of the present study was to describe the clinical characteristics and outcomes of Korean patients with MFS. Subjects and Methods We included all patients who were diagnosed with MFS between January 1995 and May 2015 at a single tertiary medical center. Patients with an MFS-related disorder including MASS phenotype (myopia, mitral valve prolapse, borderline and non-progressive aortic root dilatation, skeletal findings, and striae), mitral valve prolapse syndrome, and ectopia lentis syndrome were excluded. A total of 343 Korean patients aged ≥15 years who satisfied the revised Ghent nosology were included. Results The mean patient age at diagnosis was 35.9±12.6 years and 172 (50.1%) patients were male. Median follow-up duration was 52.8 months. A total of 303 patients (88.6%) had aortic root dilatation with Z score ≥2 or aortic root dissection. Ectopia lentis was relatively less common (163 patients, 55.1%) and systemic score ≥7 was found in 217 patients (73.8%). Among 219 probands, a family history of MFS was present in 97 patients (44.5%) and sporadic cases in 121 patients (55.5%). Among the 157 probands who underwent genetic analysis, 141 (89.8%) had an FBN1 mutation associated with aortic root aneurysm/dissection. Aortic dissection (AD) or intramural hematoma (IMH) was identified in 110 patients (32.1%). Among the 221 patients without AD or IMH, descending aortic aneurysms were identified in 19 patients (8.6%). Two hundred thirteen patients (62%) underwent cardiovascular surgery of any type. Eight patients died during follow-up. Conclusion We described the clinical characteristics and outcomes of Korean MFS patients. Cardiovascular manifestations were commonly detected and FBN1 mutation was present

    Objective: To evaluate criteria to differentiate sacral chordoma (SC), sacral giant cell tumor (SGCT) and giant sacral schwannoma (GSS) with CT and MRI. Materials and methods: CT and MR images of 22 SCs, 19 SGCTs and 8 GSSs were reviewed. The clinical and imaging features of each tumor were analyzed. Results: The mean ages of SC, SGCT and GSS were 55.1 ± 10.7, 34.3 ± 10.7 and 42.4 ± 15.7 years old. SCs (77.3%) were predominantly located in the midline of lower sacrum, while most SGCTs (73.7%) and GSSs (87.5%) were eccentrically located in upper sacrum. There were significant differences in age, location, eccentricity, morphology of bone residues, intratumoral bleeding and septations. Multiple small cysts were mainly observed in SGCTs (73.7%) with large central cysts in GSSs (87.5%). SGCTs expanded mainly inside sacrum while SCs and GSSs often extended into pelvic cavity (P = 0.0022). Involvement of sacroiliac joints and muscles were also different. Ascending extension within sacral canal was only displayed in SCs. The preservation of intervertebral discs showed difference between large and small tumors (P = 0.0002), regardless of tumor type (P = 0.095). No significant difference was displayed in gender (P = 0.234) or tumor size (P = 0.0832) among three groups. Conclusion: Age, epicenter of the lesion (midline vs. eccentric and upper vs. lower sacral vertebra), bone residues, cysts, bleeding, septation, expanding pattern, muscles and sacroiliac joint involvement can be criteria for diagnosis. Fluid–fluid level is specific for SGCTs and ascending extension within the sacral canal for SCs. The preservation of intervertebral discs is related to tumor size rather than tumor type.

Clinical characteristics and the prevalence of psychogenic tics (PT Methods. 268 consecutively examined patients aged 4 to 54 years (221 men, 47 females; 134 children, 134 adults with tic phenotype: Gilles de la Tourette syndrome (GTS, n = 255, chronic motor tics (n = 6, chronic vocal tics (n = 1, transient tics (n = 1, tics unclassified (n = 2, PT (n = 5 were analyzed. The diagnosis of tic disorders was made on the DSM-IV-TR criteria and mental disorders by psychiatrists. Results. PT were found in 5 patients (1.9%, aged 17 to 51 years, four men and one woman. The phenotype included vocalizations and complex movements. In none of the patients simple motor facial tics, inability to tic suppress, unchanging clinical pattern, peak severity from the beginning of the disease, lack of concern about the disease were present. The absence of premonitory urges, regression in unexpected positions, and the presence of atypical for GTS mental disorders were found in two persons. PT occurred in three persons in whom organic tics were present in childhood. Pharmacological treatment and psychotherapy were unsuccessful. In two persons spontaneous resolution occurred, in two patients the tics persist, in one person the course of PT is unknown. Conclusions. PT are rare and may occur in patients with organic tics. The most typical features of PT are: early onset in adulthood, lack of simple motor tics, inability to tic suppress. The diagnosis is established if a few atypical symptoms for organic tics occur.

    The incidence of cutaneous melanoma has increased significantly worldwide over the last several decades. The aim of this study is to determine clinical and morphology characteristics of primary melanoma, since some of them are important prognostic factors. This retrospective study included 172 patients. The data were collected by the Consulting team for malignant skin tumors in the Banja Luka Clinical Centre from 2009 to 2011. We did not use dermoscopy as a diagnostic tool in our investigation. We determined that melanoma occurs equally commonly in both sexes, in women in the sixth decade and the seventh in men. The most common sub-type was nodular melanoma (59.5%, P<0.05), followed by superficial spreading (27.8%) and acral lentiginous melanoma (11.4%). The most common localization was on the back in men (34.3%) and on the legs in women (P<0.05). More than half of our patients (55.8%) had melanoma thickness from 1.0 to 4.0 mm, and 38% had a melanoma thicker than 4.0 mm. The average Breslow thickness is 4.6 mm. More women than men had melanoma thicker than 4 mm (P<0.05). Spread of the primary tumor localization was found in 31.4% of patients, more frequently in men than in women (P<0.05). In most cases it was abstraction of lymph nodes (P<0.05). The average thickness of the melanoma in our patients is much higher than the average in the world and the countries of Europe. The results of this study indicate a need for better unique regional registry in this part of Bosnia and Herzegovina and improvement of preventive measures in the early diagnosis of melanoma.

Methods and materials: This retrospective study enrolled 30 subjects diagnosed with conjunctivochalasis. Complete ophthalmic examination, including visual acuity assessment, slit-lamp examination, applanation tonometry, dilated funduscopy, tear break-up time, Schirmer 1 test, and fluorescein staining were performed in all patients. Age, sex, laterality, ocular history, symptoms, and clinical findings were recorded. Results: The study included 50 eyes from 30 cases. Ages ranged from 45 to 80 years, with a mean age of 65±10 years. CChs grading were as follows: 30 (60% eyes with grade 1 CCh; 15 (30% eyes with grade 2 CCh; and five (10% eyes with grade 3 CCh. CCh was located in the inferior bulbar conjunctiva in 45 (90% eyes, and in the remaining five (10% CCh was located in the superior bulbar conjunctiva. Ten (33.3% patients had no symptoms. Dryness, eye pain, redness, blurry vision, tired eye feeling, and epiphora were the symptoms encountered in the remaining twenty (63.6% patients. Altered tear meniscus was noted in all cases. The mean tear break-up time was 7.6 seconds. The mean Schirmer 1 test score was 7 mm. Pinguecula was found in ten patients. Conclusion: Dryness, eye pain, redness, blurry vision, and epiphora were the main symptoms in patients with CCh. Dryness, eye pain, and blurry vision were worsened during downgaze and blinking. So CCh should be taken into consideration in the differential diagnosis of chronic ocular irritation and epiphora. Keywords: ocular irritation, epiphora, dryness, eye pain, blurry vision

    Increases in pancreatic enzyme levels after cardiovascular surgery were studied, and their clinical characteristics evaluated. The subjects were 128 patients who had undergone cardiovascular surgery (65 patients after valve replacement, 32 after coronary bypass surgery and 31 after aortic artificial graft replacement). The pancreatic enzyme (serum amylase and lypase) levels were monitored serially before and after operation, and amylase fractions were measured at their peaks. The relationships of the peak lypase level with underlying cardiac diseases, background factors, factors related to surgery, factors related to the extracorporeal circulation, presence or absence of symptoms, and treatments were examined. The amylase level exhibited biphasic changes consisting of a peak in which salivary glands amylase (S type) was dominant and a peak in which pancreatic amylase (P type) was dominant. The second peak coincided with the peak lypase and occurred mostly 3 to 10 days after operation. The peak lypase level exceeded the normal range in 78% of all the patients. It exceeded 564 U/l, 4 times the normal value in 28% of the patients, many of whom were symptomatic. So, we recommended that these cases should be treated as "postoperative pancreatitis". A high peak lypase level showed a significant correlation with the history of gallbladder and pancreatic diseases and diabetes mellitus among the background factors and emergency operation and the use of IABP among the surgery-related factors.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Mesenchymal stem cells (MSCs are bone marrow populating cells, different from hematopoietic stem cells, which possess an extensive proliferative potential and ability to differentiate into various cell types, including: osteocytes, adipocytes, chondrocytes, myocytes, cardiomyocytes and neurons. MSCs play a key role in the maintenance of bone marrow homeostasis and regulate the maturation of both hematopoietic and non-hematopoietic cells. The cells are characterized by the expression of numerous surface antigens, but none of them appears to be exclusively expressed on MSCs. Apart from bone marrow, MSCs are located in other tissues, like: adipose tissue, peripheral blood, cord blood, liver and fetal tissues. MSCs have been shown to be powerful tools in gene therapies, and can be effectively transduced with viral vectors containing a therapeutic gene, as well as with cDNA for specific proteins, expression of which is desired in a patient. Due to such characteristics, the number of clinical trials based on the use of MSCs increase. These cells have been successfully employed in graft versus host disease (GvHD treatment, heart regeneration after infarct, cartilage and bone repair, skin wounds healing, neuronal regeneration and many others. Of special importance is their use in the treatment of osteogenesis imperfecta (OI, which appeared to be the only reasonable therapeutic strategy. MSCs seem to represent a future powerful tool in regenerative medicine, therefore they are particularly important in medical research.

All patients underwent a full ophthalmologic assessment including visual acuity testing, slit lamp biomicroscopy, fundus examination, and evaluation of ocular alignment. The underlying causes of foveal hypoplasia were identified as albinism in five patients and aniridia in six patients. The mean logMAR visual acuity was 0.57 ± 0.24 (range 0.22-1.00) in the right eyes and 0.58 ± 0.21 (range 0.30-1.00) in the left eyes. On fundus examination in patients with albinism, two patients showed marked transparency, one patient showed moderate transparency, and two patients showed minimal transparency. Among six patients with aniridia, five patients showed normal macular pigmentation without macular reflex and one patient showed decreased macular pigmentation with no macular reflex. Patients with high grade macular hypoplasia tended to have poor visual acuities; however, the range of visual acuity was quite variable. Other factors associated with underlying disease could be the reason of this variability. Therefore, careful consideration should be given when assessing visual prognosis in foveal hypoplasia using optical coherence tomography.

    Herb induced liver injury (HILI) and drug induced liver injury (DILI) share the common characteristic of chemical compounds as their causative agents, which were either produced by the plant or synthetic processes. Both, natural and synthetic chemicals are foreign products to the body and need metabolic degradation to be eliminated. During this process, hepatotoxic metabolites may be generated causing liver injury in susceptible patients. There is uncertainty, whether risk factors such as high lipophilicity or high daily and cumulative doses play a pathogenetic role for HILI, as these are under discussion for DILI. It is also often unclear, whether a HILI case has an idiosyncratic or an intrinsic background. Treatment with herbs of Western medicine or traditional Chinese medicine (TCM) rarely causes elevated liver tests (LT). However, HILI can develop to acute liver failure requiring liver transplantation in single cases. HILI is a diagnosis of exclusion, because clinical features of HILI are not specific as they are also found in many other liver diseases unrelated to herbal use. In strikingly increased liver tests signifying severe liver injury, herbal use has to be stopped. To establish HILI as the cause of liver damage, RUCAM (Roussel Uclaf Causality Assessment Method) is a useful tool. Diagnostic problems may emerge when alternative causes were not carefully excluded and the correct therapy is withheld. Future strategies should focus on RUCAM based causality assessment in suspected HILI cases and more regulatory efforts to provide all herbal medicines and herbal dietary supplements used as medicine with strict regulatory surveillance, considering them as herbal drugs and ascertaining an appropriate risk benefit balance.

    To determine the MR features of non-sacral, non-clival chordoma and to describe a MR prototype of the lesion.Design and patients We reviewed the MR findings of 10 patients with a histologically proven chordoma (6 cervical spine, 1 thoracic spine, 3 lumbar spine). There were three female and seven male patients. Age ranged from 12 to 66 years with a mean age of 44.6 years. The MR images were reviewed for signal intensity (SI) and morphology. All lesions showed a soft tissue extension spanning several vertebral segments. Most of the lesions exhibited a so-called collar button appearance (sagittal images). Two cases of cervical chordoma displayed a ''dumbbell morphology'' (axial images) or ''mushroom'' appearance without bone involvement and with enlargement of the neuroforamen mimicking a neurogenic tumor. Although the region of the nucleus pulposus is the last part of the fetal notochord in the adult to involute, disks were surprisingly spared in all patients. Eight of 10 patients showed heterogeneous SI on all sequences. The overall SI of all lesions was isointense or slightly higher than that of muscle on T1-weighted images. All lesions exhibited high SI on T2-weighted images. After gadolinium contrast administration there was a moderate enhancement in most cases. Although the SI on MR imaging is not specific, chordoma should be considered when a destructive lesion of a vertebral body is associated with a soft tissue mass with a collar button or mushroom appearance and dumbbell morphology, spanning several vertebral segments and sparing the disk(s).

    Protons have physical characteristics, which differ from those of photons used in conventional radiotherapy. Better shielding of critical organs is obtained by using their particular ballistic (Bragg peak and lateral narrow penumbra). Some indications as ocular melanoma, chordoma and chondrosarcoma of the base of skull are now strongly accepted by the radiation oncologist community. Others are still in evaluation: meningioma, locally advanced nasopharynx tumor and paediatric tumors. The aim of this review is to present the clinical results of a technic which seems "confidential" because of the rarety and the cost of equipments.

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

    OBJECTIVE To analyse the clinical characteristics of malignant granuloma(MG) and evaluate its treatment.METHODS From March 1985 to May 1998, 101 cases of malignant granuloma were treated with radiation (RT) alone or radiotherapy followed by chemotherapy or chemotherapy followed by radiotherapy. For chemotherapy, a CCNU, COMP (CTX, VCR, MTX, PDN) or CHOP (CTX,ADM, VCR, PDN) regimen was given. Radiation was directed through the anterior field of the nose mainly for nasal and paranasal sinus malignant granuloma, and through the faciocervical field for malignant granuloma of Walderyer's ring or for patients with cervical lymphadenectasis. Total dose was 45-65 Gy over 5-6 weeks.RESULTS The overall 3-year, 5-year and 10-year survival rates were 78.2%, 56.1% and 39.7% respectively. The 5-year survival rate was: RT group 60.3%, RT + CHOP or CHOP + RT group 64.7% (P >0.05), RT +CCNU group 40%, and RT + COMP group 33.3%. The 5-year survival rates of patients with one involved focus and more than 2 involved foci were 75.6%(34/45) and 39.3% (22/56) (P<0.001). The 5-year survival rates of patients with or without body symptoms were 39.6% (18/48) and 67.9%(36/53) (P<0.05). The 5-year survival rate of the 50-60 Gy group and the <50Gy group were 60.1% (40/66) and 20% (1/5)(P <0.05). The local and regional recurrence rate was 20.8 % (21/101 ).CONCLUSION Radiotherapy alone should be the treatment of choice for patients with one site involvement and without body symptoms. Radiation fields should be large enough to include the potentially involved sites. The recommended dose is 50-60 Gy over 5-6 weeks. It is suggested that patients with more than 2 foci involvement and those with body symptoms should receive the combination therapy.

    Idiopathic portal hypertension is one of the interesting causes of portal hypertension. Even in very developed medical centers, this disorder is still one of the most important misdiagnoses of clinical practice. To inexperienced physicians, presenting esophageal varices and upper gastrointestinal bleeding usually prompt an unfortunate diagnosis of cirrhosis. A heterogenous clinical presentation and progression of this disorder should be recognized by physicians, and management should be directed towards some specific problems confined to this disorder. Although a genetic basis and other factors are implicated in its pathogenesis, exact underlying mechanism(s) is (are) unknown. In this review, we discuss the heterogeneity of idiopathic portal hypertension, its etiopathogenesis, clinical presentation and management issues. With the expectation of an excellent prognosis, a practicing gastroenterologist should be aware that "not all varices mean cirrhosis".

    2014-06-02

    Glaucoma is a neurodegenerative disorder in which degenerating retinal ganglion cells (RGC) produce significant visual disability. Clinically, glaucoma refers to an array of conditions associated with variably elevated intraocular pressure (IOP) that contributes to RGC loss via mechanical stress, vascular abnormalities, and other mechanisms, such as immune phenomena. The clinical diagnosis of glaucoma requires assessment of the ocular anterior segment with slit lamp biomicroscopy, which allows the clinician to recognize signs of conditions that can produce elevated IOP. After measurement of IOP, a specialized prismatic lens called a gonioscope is used to determine whether the angle is physically open or closed. The structural manifestation of RGC loss is optic nerve head atrophy and excavation of the neuroretinal rim tissue. Treatment is guided by addressing secondary causes for elevated IOP (such as inflammation, infection, and ischemia) whenever possible. Subsequently, a variety of medical, laser, and surgical options are used to achieve a target IOP.

    1993-06-01

    Hypotonia is a common occurrence in pediatrics, especially in the neonatal period. The hypotonic neonate represents a diagnostic challenge for the general pediatrician because hypotonia may be caused by a lesion at any level in the neuraxis: (1) central nervous system (CNS), (2) peripheral nerves (PN), (3) neuromuscular junction, or (4) muscles. Distinguishing among these pathologies is a particularly arduous task. This review will discuss the clinical approach to neonatal hypotonia with emphasis on disorders of the peripheral nervous system and muscle, and the importance of the electrophysiological study as a diagnostic test.

    Candida organisms live on the skin and mucous membranes of up to 75 percent of the population. They can live commensally without causing harm or can change to an aggressive form and invade tissue, causing both acute and chronic disease in the host. Oropharyngeal candidiasis manifests clinically as acute pseudomembranous, acute atrophic, chronic atrophic, chronic hypertrophic/hyperplastic, and angular cheilitis. Systemic infection leading to candidemia can be devastating and cause up to a 60 percent mortality rate in medical or post-surgical intensive care wards. Oral nystatin, clotrimazole, and fluconazole usually provide appropriate therapy; although resistance to medications is increasing, particularly in immunocompromised hosts.

    Full Text Available Background: ADEM, although relatively uncommon, is probably under-recognized. Objectives: To spotlight the clinical profile and therapeutic outcome of children with ADEM. Materials and Methods: This is a prospective study of patients with ADEM who were admitted to the Pediatric Departments in Aladan and Alfarawanya Hospitals in Kuwait, from January 2009 to January 2011. Clinical, microbiological and radiological data were analyzed. Results: Of 48 patients presented with acute neurological symptoms and signs, 21 patients fulfilled criteria for ADEM. 80.95% of cases were presenting in winter and spring, 57% of patients had a history of upper respiratory tract illness. The commonest presentations were motor deficits, convulsions and altered consciousness. CSF virology studies showed herpes simplex virus (HSV and Epstein-Barr virus (EBV (3 patients whereas nasal and nasopharyngeal swab showed evidence of influenza H1N1 virus (1 patient. Brain MRI was performed in all patients and revealed multiple hyperintense supratentorial brain lesions on T2/FLAIR images. 85.7% of patients had cortical and/or subcortical white matter lesions which were bilateral and asymmetric in location and size. Conclusion: ADEM although rare must be considered in children with acute onset of neurological signs and symptoms and must be distinguished from any acute neurological insult.

    1988-01-01

    Pharmacodynamic studies revealed that 150 mg of roxatidine acetate were optimal in suppressing gastric acid secretion, and that a single bedtime dose of 150 mg was more effective than a dose of 75 mg twice daily in terms of inhibiting nocturnal acid secretion. When administered orally as a capsule containing a granule formulation, the drug displayed modified-release properties, which led to a sustained suppression of gastric acid secretion. Clinical trials revealed that roxatidine acetate, 75 mg twice daily and 150 mg at night, was highly effective in healing duodenal and gastric ulcers and in reducing ulcer pain, over 4, 6, and 8 weeks of therapy. A steady reduction in diameter was observed in those ulcers not completely healed during therapy. The single bedtime dose regimen, while producing the same degree of healing as the divided daily dose during controlled clinical trials, may be of greater value in therapeutic use owing to improved patient compliance. In all efficacy criteria (cure, reduction in ulcer size, and pain relief) there was no significant difference between roxatidine acetate in a total daily dose of 150 mg, ranitidine in a total daily dose of 300 mg, and cimetidine in a total daily dose of 800 mg. Prevention of gastric and duodenal ulcer relapse was achieved by roxatidine acetate, 75 mg at night for 6 months, in about 70% of patients, as determined in open, pilot studies--a rate comparable to those reported for cimetidine and ranitidine. Roxatidine acetate shares with ranitidine an improved safety profile when compared with cimetidine. Human pharmacology studies and short-term and long-term clinical trials have all shown that roxatidine acetate is an exceptionally well tolerated compound, without the antiandrogenic activity and interference with hepatic drug metabolism which have characterized cimetidine treatment. A reason for the improved safety profile of roxatidine acetate may be its greater potency than cimetidine (six times less potent) and

    2007-02-01

    Huntington's disease is a devastating disorder with no known cure. The disease results from an expanded sequence of CAG repeats in the huntingtin gene and leads to a movement disorder with associated cognitive and systemic deficits. Huntington's disease is diagnosed by genetic testing and disease progression can be followed with a variety of imaging modalities. The accumulation of aggregated huntingtin with associated striatal degeneration is evident at autopsy. The pathophysiology of Huntington's disease remains unknown, although protein aggregation, excitotoxicity, deficits in energy metabolism, transcriptional dysregulation and apoptosis may all be involved. Current pharmacologic therapy for Huntington's disease is limited and exclusively symptomatic. However, the disease is being heavily researched, and a wide range of disease-modifying therapies is currently under development. The efficacy of these therapies is being evaluated in transgenic models of Huntington's disease and in preliminary clinical trials.

    Twenty-three cases of ovarian fibroma, comprising 3% of all benign tumors seen over a 20-year period, were analyzed. It was unilateral in all cases affecting more commonly the left ovary (70%). Whilst a majority of cases (77%) were encountered in the reproductive age group, the tumor was rare before the second decade. Only in 13% of cases was ascitis clinically detectable. This was not influenced by the size and weight (average of 9.3 x 10.8 x 11.1 cm and 959 g, respectively) of the tumors; a smooth-surfaced tumor was, however, associated with a greater amount of peritoneal fluid. Varying degrees of calcification in some tumors are detectable on ultrasonography and occasionally on abdominal radiography. The classical Meig's Syndrome was seldom encountered. The histopathological features, diagnostic problems and management are discussed.

    Seven patients with scimitar syndrome underwent retrospective clinical and echocardiographic examination. The findings were: respiratory infection with dyspnea on moderate exercise in 90%, scimitar sign in four (57%), dextrocardia in five (71%), and interatrial septal defect in five (71%), one of whom had patent ductus arteriosus. Overall, two patients had patent ductus arteriosus: one also had aortic coarctation and the other, a bicuspid aortic valve. Dilation of the right cavities was found in five (71%) and blunt edge in five (71%). In two patients, anomalous drainage was into the right atrium; in another two, into the inferior vena cava; and in three, towards the junction of the right atrium and the inferior vena cava. In three patients, drainage was obstructed. Six patients with cardiac abnormalities proceeded to surgery. Scimitar syndrome is a rare entity. In the large majority of patients (86%), diagnosis and follow-up can be performed echocardiographically.

    1999-08-27

    FG syndrome is a rare X-linked recessive form of mental retardation, first described by Opitz and Kaveggia in 1974. Based on over 50 reported cases, FG syndrome is associated with agenesis of the corpus callosum, minor facial anomalies (high, broad forehead with frontal cowlick, ocular hypertelorism, down-slanted palpebral fissures, and small cupped auricles), relative macrocephaly, broad thumbs and halluces, and prominent fetal fingertip pads. Affected individuals manifest neonatal hypotonia and severe constipation, which usually resolves during mid-childhood. The hypotonia with joint hyperlaxity evolves into spasticity with joint contractures in later life. Affability, hyperactivity, and excessive talkativeness are noted frequently in patients with FG syndrome. Recently, we described three additional families (six additional patients) with FG syndrome who support the localization of a gene for the FG syndrome in chromosome region Xq12-q21 [Graham JM Jr, Tackels D, Dibbern K, Superneau D, Rodgers C, Corning K, Schwartz CE. 1998. Am J Med Genet 80:145-156.]. Using these same families and one additional sporadic case of FG syndrome, we compared behavioral and personality characteristics of 6 FG boys with other boys with syndromic and nonsyndromic mental retardation: eight with Down syndrome, seven with Prader-Willi syndrome, eight with nonspecific mental retardation, and 13 with Williams syndrome. Using the Vineland Adaptive Behavior Scales, the Reiss Personality Profiles, and the Achenbach Child Behavior Checklist, parents were asked to characterize the behavior and personality of their boys from ages 4 to 10 years. When compared with Williams syndrome, the FG boys had fewer internalizing behaviors and were significantly less anxious and withdrawn but had similar socially oriented, attention-seeking behaviors. On the Reiss Profile, FG boys were also quite similar to Williams syndrome boys. On the Vineland Scales, FG boys demonstrated significant relative strengths

    Full Text Available Abstract Background During clinical placements, clinical educators facilitate student learning. Previous research has defined the skills, attitudes and practices that pertain to an ideal clinical educator. However, less attention has been paid to the role of student readiness in terms of foundational knowledge and attitudes at the commencement of practice education. Therefore, the aim of this study was to ascertain clinical educators’ views on the characteristics that they perceive demonstrate that a student is well prepared for clinical learning. Methods A two round on-line Delphi study was conducted. The first questionnaire was emailed to a total of 636 expert clinical educators from the disciplines of occupational therapy, physiotherapy and speech pathology. Expert clinical educators were asked to describe the key characteristics that indicate a student is prepared for a clinical placement and ready to learn. Open-ended responses received from the first round were subject to a thematic analysis and resulted in six themes with 62 characteristics. In the second round, participants were asked to rate each characteristic on a 7 point Likert Scale. Results A total of 258 (40.56% responded to the first round of the Delphi survey while 161 clinical educators completed the second (62.40% retention rate. Consensus was reached on 57 characteristics (six themes using a cut off of greater than 70% positive respondents and an interquartile deviation IQD of equal or less than 1. Conclusions This study identified 57 characteristics (six themes perceived by clinical educators as indicators of a student who is prepared and ready for clinical learning. A list of characteristics relating to behaviours has been compiled and could be provided to students to aid their preparation for clinical learning and to universities to incorporate within curricula. In addition, the list provides a platform for discussions by professional bodies about the role of placement

    The first histologically confirmed case of a classic chordoma arising in a precursor benign notochordal lesion is presented and the differential diagnosis between benign and malignant notochordal lesions is discussed. A 57-year-old man presented with a classic chordoma in the coccyx. The resected specimen demonstrated a small intraosseous benign notochordal lesion in the coccyx, which was adjacent to the classic chordoma. Also seen were two separate, similar benign lesions in the sacrum. The classic chordoma consisted of multiple lobules that were separated by thin fibrous septa and that showed cords or strands of atypical physaliphorous cells set within an abundant myxoid matrix. In contrast, the benign lesions consisted of intraosseous sheets of bland physaliphorous cells without any extracellular matrix. The affected bone trabeculae showed sclerotic reactions. It was concluded that benign and malignant notochordal lesions can be distinguished microscopically. (orig.)

    Chordomas are rare tumours arising from remnants of the embryologic notochord, typically at a midline position. Although 35-40% of these lesions are intracranial, these tumors answer for less than 1% of all intracranial tumors. The intracranial chordomas originate most frequently from the clival region at the midline. Nevertheless eventually may arise off the midline primarily in petrous apex or, very rarely, in paranasal sinuses. The authors report a case of histopathologically proved intracranial chordoma that arose atypical site in the petrous apex. The computed tomographic and magnetic resonance imaging finding were similar to those observed in midline chordomas. The computed tomographic examination revealed a well-defined soft tissue mass associated with bone destruction and foci of calcification. The magnetic resonance imaging study demonstrated a growing extra-axial formation that appeared with hypo-intensity of signal on T1-weighted images, hyperintensity on T2-weighted images and heterogeneous enhancement after paramagnetic agent injection.

    Yacovino, Dario A; Hain, Timothy C

    2013-07-01

    Cervical vertigo has long been a controversial entity and its very existence as a medical entity has advocates and opponents. Supporters of cervical vertigo claim that its actual prevalence is underestimated due to the overestimation of other diagnostic categories in clinics. Furthermore, different pathophysiological mechanisms have been attributed to cervical vertigo. Here the authors discuss the clinical characteristics of rotational vertebral artery vertigo, postwhiplash vertigo, proprioceptive cervical vertigo, and cervicogenic vertigo of old age. A clinical entity named subclinical vertebrobasilar insufficiency appears in the context of cervical osteoarticular changes. Migraine-associated vertigo may explain why some patients suffering from cervical pain have vertigo while others do not.

    Full Text Available Objective: Lichen planus (LP, is a papulosquamous inflammatory disease, which involves the skin, mucous membranes, nails and scalp. The incidence varies according to geographical regions. In this study, it was aimed to detect the clinical and demographic characteristics of the patients with LP who have been under follow-up at our clinic. Methods: One hundred sixty five patients, who were diagnosed as LP in our clinic between 2010 and 2013, were enrolled to the study. The age, gender, disease duration, time of onset of disease, characteristics of involvement, associated systemic diseases, laboratory findings and treatment were recorded retrospectively. Results: In our study, 0.6% of all patients admitted to our clinic were diagnosed as LP. A total of 165 patients included in the study, 92 women (56% and 73 men (44%, respectively. Patients’ ages ranged 8-78 (mean 44.7±16.7. Disease duration ranged from 1 month to 20 years (mean 15.6±29.7. One hundred thirty four patients (81.2% had skin involvement, 51 (31% had oral mucosal involvement, and 15 (9% had genital involvement. Five (4.5% of 111 patients with viral hepatitis tests were positive for hepatitis C virus. Hepatitis B virus positivity was seen in 4 (4% patients. Conclusion: There is a need for further studies with more patients to better understand the epidemiological, clinical and pathological characteristics of LP. We believe that our study will contribute to the determination of our country’s data.

  5. Gender differences in Parkinson's disease: clinical characteristics and cognition.

    More men than women are diagnosed with Parkinson's disease (PD), and a number of gender differences have been documented in this disorder. Examples of clinical characteristics that appear in men more often than women include rigidity and rapid eye movement behavior disorder, whereas more women than men exhibit dyskinesias and depression. Differences between men and women in cognition have not been extensively examined, though there are reports of deficits in men in aspects of cognition that contribute to activities of daily living, in verbal fluency, and in the recognition of facial emotion, and deficits in women in visuospatial cognition. Side of disease onset may interact with gender to affect cognitive abilities. One possible source of male-female differences in the clinical and cognitive characteristics of PD is the effect of estrogen on dopaminergic neurons and pathways in the brain. This effect is not yet understood, as insight into how the fluctuation of estrogen over the lifetime affects the brain is currently limited. Further attention to this area of research will be important for accurate assessment and better management of PD. Attention should also be directed to multiple covariates that may affect clinical characteristics and cognition. Knowledge about differences in the presentation of PD symptoms in men and women and about the pathophysiology underlying those differences may enhance the accuracy and effectiveness of clinical assessment and treatment of the disease.

  6. Genetic characteristics of Japanese clinical Listeria monocytogenes isolates.

    Full Text Available Listeria monocytogenes causes foodborne illnesses through consumption of ready-to-eat foods. Although 135-201annual listeriosis cases have been estimated in Japan, the details regarding the clinical isolates such as infection source, virulence level, and other genetic characteristics, are not known. In order to uncover the trends of listeriosis in Japan and use the knowledge for prevention measures to be taken, the genetic characteristics of the past human clinical isolates needs to be elucidated. For this purpose, multilocus tandem-repeat sequence analysis (MLTSA and multi-virulence-locus sequence typing (MVLST were used in this study. The clinical isolates showed a variety of genetically distant genotypes, indicating they were from sporadic cases. However, the MVLST profiles of 7 clinical isolates were identical to those of epidemic clone (EC I isolates, which have caused several serious outbreaks in other countries, suggesting the possibility that they have strong virulence potential and originated from a single outbreak. Moreover, 6 Japanese food isolates shared their genotypes with ECI isolates, indicating that there may be risks for listeriosis outbreak in Japan. This is the first investigational study on genetic characteristics of Japanese listeriosis isolates. The listeriosis cases happened in the past are presumably sporadic, but it is still possible that some isolates with strong virulence potential have caused listeriosis outbreaks, and future listeriosis risks also exist.

    2015-07-01

    A 19-year-old female Bengal tiger (Panthera tigris tigris) was presented with hind limb weakness, ataxia and respiratory distress. Computed tomography revealed a mass between the left side of the T7 vertebra and the base of the left 7th rib. The tiger then died, and necropsy was performed. Grossly, the vertebral mass was 6 × 5.7 × 3 cm, and invaded the adjacent vertebral bone and compressed the T7 spinal cord. Histologically, the mass was composed of large, clear, vacuolated and polygonal cells with osteochondral matrix. Cellular and nuclear atypia were moderate. The vacuolated cells stained positively for cytokeratin and vimentin and negatively for S-100. Based on these findings, the present case was diagnosed as a vertebral chordoma; the first report in a tiger.

    Knowledge of illness perception may aid the identification of groups of patients with a higher risk of coping poorly with the demands of their illness. This study aims to investigate associations between illness perception, clinical characteristics, patient knowledge, quality of life and subjective health in persons with psoriasis. The present study was based on cross-sectional data from patients awaiting climate therapy in Gran Canaria. We included 254 eligible patients (74%) who completed a questionnaire including the revised Illness Perception Questionnaire, the Psoriasis Knowledge Questionnaire, and the Dermatological Life Quality Index. Disease severity was measured using the Psoriasis Area and Severity Index. Several statistically significant associations between clinical characteristics, knowledge and various illness perception dimensions were found. Illness perception was also significantly related to disease-specific quality of life and subjective health. These findings contradict previous findings, which suggested that objective disease factors are not relevant to illness perception in psoriasis.

    Liver cancer is an aggressive malignant disease with a poor prognosis. Patients with liver cancer are usually diagnosed at an advanced stage and thus miss the opportunity for surgical resection. Chemotherapy and radiofrequency ablation, which target tumor bulk, have exhibited limited therapeutic efficacy to date. Liver cancer stem cells (CSCs) are a small subset of undifferentiated cells existed in liver cancer, which are considered to be responsible for liver cancer initiation, metastasis, relapse and chemoresistance. Elucidating liver CSC characteristics and disclosing their regulatory mechanism might not only deepen our understanding of the pathogenesis of liver cancer but also facilitate the development of diagnostic, prognostic and therapeutic approaches to improve the clinical management of liver cancer. In this review, we will summarize the recent advances in liver CSC research in terms of the origin, identification, regulation and clinical correlation.

    Full Text Available INTRODUCTION: Persistent postural-perceptual dizziness is the dizziness that lasts for over three months with no clinical explanation for its persistence. The patient's motor response pattern presents changes and most patients manifest significant anxiety. OBJECTIVE: To evaluate the clinical characteristics of patients with persistent postural and perceptual dizziness. METHODS: statistical analysis of clinical aspects of patients with persistent postural-perceptual dizziness. RESULTS: 81 patients, average age: 50.06 ± 12.16 years; female/male ratio: 5.7/1; main reasons for dizziness: visual stimuli (74%, body movements (52%, and sleep deprivation (38%. The most prevalent comorbidities were hypercholesterolemia (31%, migraine headaches (26%, carbohydrate metabolism disorders (22% and cervical syndrome (21%. DHI, State-Trait Anxiety Inventory - Trait, Beck Depression Inventory, and Hospital Anxiety and Depression Scale questionnaires were statistically different (p < 0.05 when compared to controls. 68% demonstrated clinical improvement after treatment with serotonin reuptake inhibitors. CONCLUSION: Persistent postural-perceptual dizziness affects more women than men, with a high associated prevalence of metabolic disorders and migraine. Questionnaires help to identify the predisposition to persistent postural-perceptual dizziness. The prognosis is good with adequate treatment.

    Abstract A retrospective cross-sectional study using data from an outpatient clinic in China was conducted to investigate the clinical features of early-onset gout patients. All patients diagnosed with gout were asked about clinical characteristics of their gout and comorbid diseases. Patients presenting with acute flares were asked about common triggers before the flare. “Early-onset” gout was defined as onset of gout before 40 years and “late-onset” as onset ≥40 years. Major joint involvement, flare frequency before presentation, the cumulative number of involved joints, proportions of tophi complications at presentation, flare triggers, as well as any metabolic, cardiovascular, cerebrovascular, and renal comorbidities, were compared between the 2 groups. A total of 778 gout patients were enrolled in this study, including 449 (57.7%) in the early-onset group and 329 (42.3%) in the late-onset group. Compared with the late-onset gout patients, the early-onset gout patients had a higher proportion of ankle/mid-foot involvement (62.8% vs 48.2%, P gout patients had fewer metabolic, cardiovascular, cerebrovascular, or renal complications. Early- and late-onset gout patients had different clinical features. Early-onset seems to be influenced more by lifestyle, while late-onset patients have more complications because of comorbidities.

    Full Text Available Background and Design: The purpose of this study was to obtain data that may provide an insight into the etiopathogenesis of recurrent aphtous stomatitis (RAS by the way of analysing the sociodemographic and clinical characteristics of patients who had been diagnosed with RAS. Materials and Metods: The patients, who were diagnosed with RAS in the dermatology outpatient clinic, between May 2007 and May 2010, were evaluated retrospectively. The data including sociodemografic and clinical characteristics, and treatment options were recorded. Results: A hundred patients (68 women, 32 men were included in this study. The average age was 40±13.6 years. RAS was more common in patients with middle-income and low education. The most common type of RAS was minor aphtous ulcers (88%. The lesions were most frequently seen on the lateral side of the tongue (34% and cheek (34%. Sixty percent of patients had a positive family history. Some factors such as biting (12%, tooth brushing (18%, dental disease presence (82%, food (39%, menstruation (10.3%, stress (76%, iron deficiency (16.7%, vitamin B12 deficiency (22.4%, low serum ferritin levels (18%, and seasonal variability (32% showed positive correlation with RAS. A negative correlation was found between RAS and smoking. Forty-nine percent of patients had used alternative therapies in addition to drug therapy. The most frequently used alternative method was consumption of sumac (26.5%. Conlucions: In contrast to the literature, our study found that RAS is started in the third decade of life and, approximately 50% of patients prefered alternative treatment methods, particularly sumac. Nowadays, discussions about the etiopathogenesis of RAS continue. In this study, we found that different sociodemographic and clinical factors may be associated with the etiopathogenesis of the disease. Our study will be followed by further studies using prospective design to identify the the etiopathogenesis of RAS.

Awareness about this disorder may help prevent misdiagnosis and inappropriate investigations and treatment. The objective of the study was to evaluate the clinical and laboratory characteristics of histopathologically confirmed cases of Kikuchi′s disease from a tertiary care center in southern India. Materials and Methods: Retrospective analysis of all adult patients with histopathologically confirmed Kikuchi′s disease from January 2007 to December 2011 in a 2700-bed teaching hospital in South India was done. The clinical and laboratory characteristics and outcome were analyzed. Results: There were 22 histopathologically confirmed cases of Kikuchi′s disease over the 5-year period of this study. The mean age of the subjects′ was 29.7 years (SD 8.11 and majority were women (Male: female- 1:3.4. Apart from enlarged cervical lymph nodes, prolonged fever was the most common presenting complaint (77.3%. The major laboratory features included anemia (54.5%, increased erythrocyte sedimentation rate (31.8%, elevated alanine aminotransferase (27.2% and elevated lactate dehydrogenase (LDH (31.8%. Conclusion: Even though rare, Kikuchi′s disease should be considered in the differential diagnosis of young individuals, especially women, presenting with lymphadenopathy and prolonged fever. Establishing the diagnosis histopathologically is essential to avoid inappropriate investigations and therapy.

    [Purpose] To describe the clinical characteristics affecting motor recovery and ambulation in stroke patients. [Subjects and Methods] Demographic and clinical characteristics of 53 stroke patients (31 M, 22 F), such as age, gender, etiology, hemiplegic side, Brunnstrom stage, functional ambulation scale scores, history of rehabilitation, and presence of shoulder pain and complex regional pain syndrome were evaluated. [Results] The etiology was ischemic in 79.2% of patients and hemorrhagic in 20.8%. Brunnstrom hand and upper extremity values in females were lower than in males. Complex regional pain syndrome was observed at a level of 18.9% in all patients (more common in females). Brunnstrom hand stage was lower in complex regional pain syndrome patients than in those without the syndrome. Shoulder pain was present in 44.4% of patients. Brunnstrom lower extremity values and functional ambulation scale scores were higher in rehabilitated than in non-rehabilitated cases. [Conclusion] Brunnstrom stages of hand and upper extremity were lower and complex regional pain syndrome was more common in female stroke patients. Shoulder pain and lower Brunnstrom hand stages were related to the presence of complex regional pain syndrome. PMID:28265142

    Full Text Available Background: Takotsubo cardiomyopathy (TC or transient left ventricular apical ballooning syndrome is an acute cardiac syndrome characterized by transient wall motion abnormalities extending beyond a single epicardial vessel in the absence of significant obstructive coronary artery disease. Aim: This study was to describe the clinical characteristics of TC in North America. Materials and Methods: We identified 10 patients who met the Mayo Clinic criteria for TC using our Electronic Medical Records. We also conducted a systematic review of case series of TC that were done in North America by searching the MEDLINE database. We identified 11 case series that met our eligibility criteria. Results: Our systematic review included 620 patients. Chest pain and ST segment elevation were the cardinal features of this syndrome, but the prevalence was lower than in the European and Asian cohort (50% and 39% as compared with 80% and 70%, respectively. Classic precipitating emotional or physical stress was described in > 80% of patients. Cardiac biomarkers were found to be elevated in >90% of our patients. Conclusions : TC is a worldwide problem and clinical presentation appears to be similar in North American, European, and Asian countries. However, fewer patients in our cohort presented with typical chest pain and electrocardiography (ECG changes, which might suggest ethnic variations in the syndrome or perhaps a more aggressive diagnostic approach in North American countries.

    Community-acquired Acinetobacter baumannii (CA-Ab) is a rare but serious cause of community-acquired pneumonia in tropical regions of the world. CA-Ab infections predominantly affect individuals with risk factors, which include excess alcohol consumption, diabetes mellitus, smoking and chronic lung disease. CA-Ab pneumonia presents as a surprisingly fulminant course and is characterized by a rapid onset of fever, severe respiratory symptoms and multi-organ dysfunction, with a mortality rate reported as high as 64%. It is unclear whether the distinct clinical syndrome caused by CA-Ab is because of host predisposing factors or unique bacterial characteristics, or a combination of both. Deepening our understanding of the drivers of overwhelming CA-Ab infection will provide important insights into preventative and therapeutic strategies.

    Candida spp. is an invasive infectious fungus, a major risk factor that can increase morbidity and mortality in hospitalized patients. In this study, 2,508 Candida spp. were isolated from various clinical specimens collected from university hospitals from July 2011 to October 2014. They were identified in order to determine isolation frequencies and characteristics by specimen, gender, age group, year, season, and month. The strain-specific isolation rate of Candida spp. is in the order of Candida albicans (1,218 strains, 48.56%), Candida glabrata (416 strains, 16.59%), Candida utilis (305 strains, 12.16%), Candida tropicalis (304 strains, 12.12%), and Candida parapsilosis (116 strains, 4.63%) and these five species accounted for more than 94% of the total strains. Of the specimens, Candida spp. were most frequently isolated from urine-catheter, followed by urine-voided, blood, sputum, other, open pus, vaginal discharge, Tip, ear discharge, bronchial aspiration and bile, in that order. Looking at the age distribution, the detection rate of patients in their 60s and older was significantly higher at 75.8% (1,900/2,508). The detection rate of patients in their 20s and younger was shown to be very low at 2.55% (64/2,508). By year, the detection rate of non-albicans Candida spp. showed a tendency to gradually increase each year compared with C. albicans. As isolation of Candida spp. from clinical samples at the specie level can vary depending on characteristics of the patient, sample, season, etc., continual studies are required.

    Marfan syndrome is an autosomal dominant heritable disorder of the connective tissue, caused by mutations of the gene FBN1, which encodes fibrillin-1, a major component of the microfibrils of the extracellular matrix. Fibrillin-1 interacts with transforming growth factor-β (TGF-β), and dysregulated TGF-β signaling plays a major role in the development of connective tissue disease and familial aortic aneurysm and dissection, including Marfan syndrome. Losartan, an angiotensin II blocker, has the potential to reduce TGF-β signaling and is expected to be an additional therapeutic option. Clinical diagnosis is made using the Ghent nosology, which requires comprehensive patient assessment and has been proven to work well, but evaluation of some of the diagnostic criteria by a single physician is difficult and time-consuming. A Marfan clinic was established at the University of Tokyo Hospital in 2005, together with cardiologists, cardiac surgeons, pediatricians, orthopedists, and ophthalmologists in one place, for the purpose of speedy and accurate evaluation and diagnosis of Marfan syndrome. In this review, we discuss the recent progress in diagnosis and treatment of Marfan syndrome, and the characteristics of Japanese patients with Marfan syndrome.

    To describe the clinical and epidemiological characteristics of patients with severe infectious keratitis in Asunción, Paraguay between April 2009 and September 2011. All patients with the clinical diagnosis of severe keratitis (ulcer ≥2 mm in size and/or central location) were included. Empiric treatment consisted of topical antibiotics and antimycotics; in cases of advanced keratitis, fortified antibiotics were used. After microbiological analysis, treatment was changed if indicated. In total 48 patients (62.5 % males, 25 % farmers) were included in the analysis. A central ulcer was found in 81.3 % (n = 39). The median delay between onset of symptoms and time of first presentation at our institution was 7 days (range 1-30 days). Fungal keratitis was diagnosed in 64.5 % (n = 31) of patients, of which Fusarium sp. (n = 17) was the most common. Twenty-one patients (43.8 %) reported previous trauma to the eye. The globe could be preserved in all cases. While topical therapy only was sufficient in most patients, a conjunctival flap was necessary in six patients suffering from fungal keratitis. The high rate of fungal keratitis in this series is remarkable, and microbiological analysis provided valuable information for the appropriate treatment. In this setting, one has to be highly suspicious of fungal causes of infectious keratitis.

    Full Text Available Objective: In this study, we aimed to evaluate clinical and laboratory characteristics of patients with Kawasaki disease (KD in Konya region of Turkey. Methods: The hospital records of patients who were hospitalized with the diagnosis of KD in the Pediatrics Clinics of Konya Training and Research Hospital between May 2010 and June 2012 were reviewed retrospectively. Results: Seven cases were found to have the diagnosis of KD, two of whom were incomplete KD. Oropharynx changes were the most common (100% feature in our patients. Five (71% patients had bulbar conjunctivitis. Three (43% patients had erythema at the site of BCG inoculation. Adenopathy was present in all of our patients with the classical form. A desquamation was observed in one case at the seventh day of fever. No cardiac manifestation was seen. Elevated erythrocyte sedimentation rate and thrombocytosis were present in all patients. All of the patients were received intravenous immunoglobulin in the first ten days of the fever. Conclusion: KD should be considered as a possible diagnosis in any child presenting with prolonged fever. BCG reaction can be attributed as a diagnostic criterion for incomplete form of the disease especially in countries where BCG vaccination is routinely performed. Early treatment is essential to prevent cardiovascular complications.

    Leprosy is a chronic disease caused by Mycobacterium leprae. Although the occurrence of leprosy has declined in Saudi Arabia, it has not yet been eradicated. To our knowledge, this descriptive retrospective study is the first to assess the clinical presentation of leprosy at the time of diagnosis in Saudi Arabia. All study subjects were leprosy patients admitted to Ibn Sina hospital, the only referral hospital for leprosy in Saudi Arabia, between January 2000 and May 2012. A total of 164 subjects, the majority of whom (65%) were between 21 and 50 years of age, were included, and the male-to-female ratio was 2.8:1. Of these 164 patients, 63% were Saudis, and 77% of all admitted patients were from the western region. Lepromatous leprosy was observed most frequently (33%), and 31% of cases had a positive history of close contact with leprosy. At the time of diagnosis, 84% of all subjects presented with skin manifestation. The prevalence of neurological deficit at the time of diagnosis was 87%. Erythema nodosum leprosum (E.N.L.) developed in only 10% of all subjects. Further studies are needed to determine the clinical characteristics pertaining to each type of leprosy in the region, and training courses in caring for and diagnosing patients with leprosy should be organized for health workers.

    Full Text Available Abstract Background Clinical trial and epidemiological studies need high quality biospecimens from a representative sample of participants to investigate genetic influences on treatment response and disease. Obtaining blood biospecimens presents logistical and financial challenges. As a result, saliva biospecimen collection is becoming more frequent because of the ease of collection and lower cost. This article describes an assessment of saliva biospecimen samples collected through the mail, trial participant demographic and behavioral characteristics, and their association with saliva and DNA quantity and quality. Methods Saliva biospecimens were collected using the Oragene® DNA Self-Collection Kits from participants in a National Cancer Institute funded smoking cessation trial. Saliva biospecimens from 565 individuals were visually inspected for clarity prior to and after DNA extraction. DNA samples were then quantified by UV absorbance, PicoGreen®, and qPCR. Genotyping was performed on 11 SNPs using TaqMan® SNP assays and two VNTR assays. Univariate, correlation, and analysis of variance analyses were conducted to observe the relationship between saliva sample and participant characteristics. Results The biospecimen kit return rate was 58.5% among those invited to participate (n = 967 and 47.1% among all possible COMPASS participants (n = 1202. Significant gender differences were observed with males providing larger saliva volume (4.7 vs. 4.5 ml, p = 0.019, samples that were more likely to be judged as cloudy (39.5% vs. 24.9%, p 0.21, P Conclusion Findings from this study show that demographic and behavioral characteristics of smoking cessation trial participants have significant associations with saliva and DNA metrics, but not with the performance of TaqMan® SNP or VNTR genotyping assays. Trial registration COMPASS; registered as NCT00301145 at clinicaltrials.gov.

    AIM: To investigate the clinical characteristics and prognostic factors of a consecutive series of patients with severe acute pancreatitis (SAP).METHODS: Clinical data of SAP patients admitted to our hospital from January 2003 to January 2004 were retrospectively reviewed. Collected data included the age, gender, etiology,length of hospitalization, APACHE Ⅱ score at admission,local and organ/systemic complications of the patients.RESULTS: Of the 268 acute pancreatitis patients, 94 developed SAP. The mean age of SAP patients was 52 years, the commonest etiology was cholelithiasis (45.7%), the mean length of hospitalization was 70 d, the mean score of APACHE Ⅱ was 7.7. Fifty-four percent of the patients developed necrosis, 25% abscess, 58% organ/systemic failure. A total of 23.4% (22/94) of the SAP patients died. Respiratory failure was the most common organ clysfunction (90.9%) in deceased SAP patients, followed by cardiovascular failure (86.4%),renal failure (50.0%). In the SAP patients, 90.9% (20/22)developed multiple organ/systemic failures. There were significant differences in age, length of hospitalization,APACHE Ⅱ score and incidences of respiratory failure, renal failure, cardiovascular failure and hematological failure between deceased SAP patients and survived SAP patients.By multivariate logistic regression analysis, independent prognostic factors for mortality were respiratory failure,cardiovascular failure and renal failure.CONCLUSION: SAP patients are characterized by advanced age, high APACHE Ⅱ score, organ failure and their death is mainly due to multiple organ/systemic failures. In patients with SAP, respiratory, cardiovascular and renal failures can predict the fatal outcome and more attention should be paid to their clinical evaluation.

    Claudin-low breast cancer is a molecular type of breast cancer originally identified by gene expression profiling and reportedly associated with poor survival. Claudin-low tumors have been recognised to preferentially display a triple-negative phenotype, however only a minority of triple-negative breast cancers are claudin-low. We sought to identify an immunohistochemical profile for claudin-low tumors that could facilitate their identification in formalin fixed paraffin embedded tumor material. First, an in silico collection of ~1600 human breast cancer expression profiles was assembled and all claudin-low tumors identified. Second, genes differentially expressed between claudin-low tumors and all other molecular subtypes of breast cancer were identified. Third, a number of these top differentially expressed genes were tested using immunohistochemistry for expression in a diverse panel of breast cancer cell lines to determine their specificity for claudin-low tumors. Finally, the immunohistochemical panel found to be most characteristic of claudin-low tumors was examined in a cohort of 942 formalin fixed paraffin embedded human breast cancers with >10 years clinical follow-up to evaluate the clinico-pathologic and survival characteristics of this tumor subtype. Using this approach we determined that claudin-low breast cancer is typically negative for ER, PR, HER2, claudin 3, claudin 4, claudin 7 and E-cadherin. Claudin-low tumors identified with this immunohistochemical panel, were associated with young age of onset, higher tumor grade, larger tumor size, extensive lymphocytic infiltrate and a circumscribed tumor margin. Patients with claudin-low tumors had a worse overall survival when compared to patients with luminal A type breast cancer. Interestingly, claudin-low tumors were associated with a low local recurrence rate following breast conserving therapy. In conclusion, a limited panel of antibodies can facilitate the identification of claudin-low tumors

    Full Text Available Introduction: Intensive care mortality of HIV-positive patients has progressively decreased. However, critically ill HIV-positive patients with sepsis present a worse prognosis. To better understand this condition, we propose a study comparing clinical, etiological and inflammatory data, and the hospital course of HIV-positive and HIV-negative patients with severe sepsis or septic shock. Methods: A prospective observational study enrolling patients with severe sepsis or septic shock associated or not with HIV infection, and admitted to intensive care unit (ICU. Clinical, microbiological and inflammatory parameters were assessed, including C-reactive protein (CRP, procalcitonin (PCT, interleukin-6, interleukin-10 and TNF-α. Outcome measures were in-hospital and six-month mortality. Results: The study included 58 patients with severe sepsis/septic shock admitted to ICU, 36 HIV-positive and 22 HIV-negative. All HIV-positive patients met the criteria for AIDS (CDC/2008. The main foci of infection in HIV-positive patients were pulmonary and abdominal (p=0.001. Fungi and mycobacteria were identified in 44.4% and 16.7% of HIV-positive patients, respectively. In contrast, the main etiologies for sepsis in HIV-negative patients were Gram-negative bacilli (36.4% and Gram-positive cocci (36.4% (p=0.001. CRP and PCT admission concentrations were lower in HIV-positive patients (130 vs. 168 mg/dL p=0.005, and 1.19 vs. 4.06 ng/mL p=0.04, respectively, with a progressive decrease in surviving patients. Initial IL-10 concentrations were higher in HIV-positive patients (4.4 pg/mL vs. 1.0 pg/mL, p=0.005, with moderate accuracy for predicting death (area under receiver-operating characteristic curve =0.74. In-hospital and six-month mortality were higher in HIV-positive patients (55.6 vs. 27.3% p=0.03, and 58.3 vs. 27.3% p=0.02, respectively. Conclusions: The course of sepsis was more severe in HIV-positive patients, with distinct clinical, etiological and

    Full Text Available Objective: The aim of this study is to present a comprehensive profile of clinical and psychosocial characteristics of children with psychogenic nonepileptic seizures and to assess the short-term outcome of these patients. Materials and Methods: The subjects were consecutive cases of children with a diagnosis of nonepileptic seizures (N=17, mean age = 10.7 years, S.D. = 1.26 and two groups of control groups matched on age and sex: true seizure group and healthy controls. All the children were recruited from the out-patient services of the Department of Pediatrics of a tertiary care teaching hospital in North India. Detailed history taking and clinical examination was done in the case of every child. A standard 18 channel EEG was done in all the children and a video EEG was done in 12 cases of children with nonepileptic seizures. The Childhood Psychopathology Measurement Schedule (CPMS and Life Events Scale for Indian Children (LESIC were used to measure the children′s emotional and behavioral functioning at home, and the number of life events and the stress associated with these events in the preceding year and the year before that. Short-term outcome was examined three to six months after the diagnosis of nonepileptic seizures was made. Results: Unresponsiveness without marked motor manifestations was the most common "ictal" characteristic of the nonepileptic seizures. Pelvic thrusting, upper and lower limb movements, head movements, and vocalization were observed in less than one-third of the patients. Increased psychosocial stress and significantly higher number of life events in the preceding year were found to characterize children with nonepileptic seizures, as compared to the two control groups. The nonepileptic seizures and true seizures groups had a higher proportion of children with psychopathology scores in the clinically significant maladjustment range, as compared to those in the healthy control group. A majority of the patients

    Objective To investigate the clinical characteristics of fetal hydrops and to find the antenatal ultrasound findings predictive of adverse perinatal outcome. Methods This is a retrospective study of 42 women with fetal hydrops who delivered in a tertiary-referral center from 2005 to 2013. Fetal hydrops was defined as the presence of fluid collection in ≥2 body cavities: ascites, pleural effusion, pericardial effusion, and skin edema. Predictor variables recorded included: maternal characteristics, gestational age at diagnosis, ultrasound findings, and identifiable causes. Primary outcome variables analyzed were fetal death and neonatal death. Results The mean gestational age at diagnosis was 29.3±5.4 weeks (range, 18 to 39 weeks). The most common identifiable causes were cardiac abnormality (10), followed by syndrome (4), aneuploidy (3), congenital infection (3), twin-to-twin transfusion syndrome (3), non-cardiac anormaly (2), chorioangioma (2), inborn errors of metabolism (1), and immune hydrops by anti-E antibody isoimmunization (1). Thirteen cases had no definite identifiable causes. Three women elected termination of pregnancy. Fetal death occurred in 4 cases. Among the 35 live-born babies, only 16 survived (54.0% neonatal mortality rate). Fetal death and neonatal mortality rate was not significantly associated with Doppler velocimetry indices or location of fluid collection, but increasing numbers of fluid collection site was significantly associated with a higher risk of neonatal death. Conclusion The incidence of fetal hydrops in our retrospective study was 24.4 per 10,000 deliveries and the perinatal mortality rate was 61.9% (26/42). The number of fluid collection sites was the significant antenatal risk factor to predict neonatal death. PMID:25798421

    The surgical results of 18 cases of clival/upper cervical chordoma treated in the last decade via the endoscopic endonasal approach (EEA, 9 cases) and the transoral-transpalatal approach (TO-TPA, 9 cases) were compared. Each group showed the same incidence of subdural invasion, with 5 cases each. The superior (frontal base) and lateral surgical fields were wider by EEA, but the inferior view lower than the cranio-vertebral junction (CVJ) was wider by TO-TPA. Gross total removal was achieved in 3 cases in the EEA group, but in only 1 case in the TO-TPA group. Differences in radicality might be due to the extent of the lateral and subdural overview. However for large tumors extending below the CVJ, TO-TPA was the only viable approach for surgical removal. Surgical complications were higher in the EEA (4 cases) than the TO-TPA group (1 case), and were mainly caused by aggressive management of subdural invasion in the EEA group. Post-operative oral intake was earlier and the operative time was shorter in the EEA group. The surgical results were more radical and less invasive in the EEA group than the TO-TPA group. However in tumors extending below the CVJ, the surgical field in EEA was limited, indicating the need to use the transoral route or a combination of routes. A higher complication rate following subdural management was a negative factor that requires improvement in the EEA group and two-staged EEA followed by a transcranial approach may be considered for the cases with subdural invasion.

    ·AIM: To describe the clinical characteristics of Turkish patients with intermediate uveitis(IU) and to investigate the effect of clinical findings and complications on final visual acuity(VA).·METHODS: We retrospectively analyzed the medical records of patients with IU who had at least 6mo of follow-up and were older than 16 y.· RESULTS: A total of 78 eyes of 45 patients were included in the study and the mean follow-up period was19.4mo. The mean age at the time of presentation was42.9s. Systemic disease associations were found in17.7% of cases; sarcoidosis(8.8%) and multiple sclerosis(6.6%) were the most common diseases. Recurrence rate(odds ratio=45.53; 95%CI: 2.181-950.58), vitritis equals to or more than 3+ cells(odds ratio =57.456; 95%CI: 4.154-794.79) and presenting with VA less than 20/40(odds ratio =43.81; 95% CI: 2.184-878.71) were also found as high risk factors for poor final VA. At the last follow-up examination, 67.9% of eyes had VA of 20/40 or better.·CONCLUSION: IU is frequently seen at the beginning of the fourth decade of life. The disease is most commonly idiopathic in adult Turkish patients. Patients with severe vitritis at presentation and patients with frequent recurrences are at high risk for poor visual outcome.

  18. Trauma-associated tinnitus: audiological, demographic and clinical characteristics.

    Full Text Available BACKGROUND: Tinnitus can result from different etiologies. Frequently, patients report the development of tinnitus after traumatic injuries. However, to which extent this specific etiologic factor plays a role for the phenomenology of tinnitus is still incompletely understood. Additionally, it remains a matter of debate whether the etiology of tinnitus constitutes a relevant criterion for defining tinnitus subtypes. OBJECTIVE: By investigating a worldwide sample of tinnitus patients derived from the Tinnitus Research Initiative (TRI Database, we aimed to identify differences in demographic, clinical and audiological characteristics between tinnitus patients with and without preceding trauma. MATERIALS: A total of 1,604 patients were investigated. Assessment included demographic data, tinnitus related clinical data, audiological data, the Tinnitus Handicap Inventory, the Tinnitus Questionnaire, the Beck Depression Inventory, various numeric tinnitus rating scales, and the World Health Organisation Quality of Life Scale (WHOQoL. RESULTS: Our data clearly indicate differences between tinnitus patients with and without trauma at tinnitus onset. Patients suffering from trauma-associated tinnitus suffer from a higher mental burden than tinnitus patients presenting with phantom perceptions based on other or unknown etiologic factors. This is especially the case for patients with whiplash and head trauma. Patients with posttraumatic noise-related tinnitus experience more frequently hyperacousis, were younger, had longer tinnitus duration, and were more frequently of male gender. CONCLUSIONS: Trauma before tinnitus onset seems to represent a relevant criterion for subtypization of tinnitus. Patients with posttraumatic tinnitus may require specific diagnostic and therapeutic management. A more systematic and - at best - standardized assessment for hearing related sequelae of trauma is needed for a better understanding of the underlying pathophysiology and

    Holoprosencephaly is a brain defect resulting from incomplete cleavage of the embryonic forebrain. It involves forebrain and facial malformations that can range from mild to severe. The epidemiology of holoprosencephaly is largely unknown. Published prevalence estimates have been derived from clinic-based case series, and suggested risk factors for holoprosencephaly have been identified in case reports, without confirmation from systematically conducted population-based studies. Using data from a population-based birth defects registry in California, we described the epidemiologic and clinical characteristics of cytogenetically and phenotypically distinct types of holoprosencephaly. A total of 121 cases was identified among a cohort of 1,035,386 live births and fetal deaths. The prevalence of holoprosencephaly was 1.2 per 10,000 births (95% confidence interval 1.0-1.4 per 10,000). Of all cases, 41% (50/121) had a chromosomal abnormality, most commonly Trisomy 13. Among the 71 cytogenetically apparently normal cases, 18 had recognizable syndromes and the remaining 53 were of unknown cause. Among the cytogenetically abnormal cases, females had a greater risk than males (odds ratio = 2.3, 95% confidence interval [1.2, 4.4]). Among the cytogenetically normal cases, increased risks were observed among Hispanic whites (OR = 1.8 [0.9, 3.6]) and cases whose mother was born in Mexico (OR = 2.2 [1.0, 4.5]). Approximately 46% of all cases had alobar holoprosencephaly, the most severe form of the forebrain malformation. The facial phenotype did not strongly predict the severity of the brain defect; however, severity was inversely correlated with length of survival. This study is the first to present findings based on such a large population-based series of infants/fetuses affected by holoprosencephaly, and demonstrates the importance of investigating the component subgroups of this rare phenotype. 47 refs., 7 tabs.

    Full Text Available Background and Aims: Infection with hepatitis A virus is still one of the most common causes of hepatitis worldwide. The clinical manifestation of acute hepatitis A (AHA in adults can vary greatly, ranging from asymptomatic infection to severe and fulminant hepatitis. The aim of this study was to describe the demographic, clinical characteristics, laboratory features and hospital outcome of adult patients with AHA over a consecutive period of 4 years within an area from Eastern European country. Methods: Two hundred and two adult patients diagnosed with AHA were retrospective, observational and analytic analized over a period of 4 years. Based on prothrombin time less than 50, the study group was stratified in medium (79.2% and severe forms (20.8%. We investigated the clinical, laboratory and epidemiological features. Statistical analysis were applied to compare the medium and severe forms of AHA. Results: Most patients (72.7% were younger than 40 years. The main symptoms included: dyspepsia (72.07%, jaundice (86.63%, asteno-adynamia (86.72%, and flu-like symptoms (53.46%. The hemorrhagic cutaneous-mucous manifestations (6.93% associated with the severe forms of AHA (OR =12.19, 95%CI -3.59 - 41.3, p =0.001. We found statistically significant differences for PT (p <0.001, INR (p <0.001, TQ (p <0.001, ALAT (p <0.001, ASAT (p <0.001, ALP (p <0.001 and platelets (p =0.009 between severe and medium AHA forms. We found that TQ, INR, ALAT and ASAT have the highest diagnostic values, statistically significant (p <0.05 for severe AHA forms with AUC (0.99, 0.99, 0.72, 0.70 at values of sensitivity (95%, 90.5%, 89%, 95% and specificity (98%, 99%, 88%,94%. Conclusions Medium severity AHA forms were found in most of the study group patients (79.2%. The severe AHA forms were associated with hemorrhagic cutaneous-mucous manifestations (OR =12.19, p =0.001. The univariate analysis proved a negatively statistically significant correlation between IP and ALAT

    Objective The objectives of this study were to describe the clinical characteristics and outcomes of poisoning by zinc phosphide, a common rodenticide in Thailand, and to evaluate whether these outcomes can be prognosticated by the clinical presentation. Materials and methods A 3-year retrospective cohort study was performed using data from the Ramathibodi Poison Center Toxic Exposure Surveillance System. Results In total, 455 poisonings were identified. Most were males (60.5%) and from the central region of Thailand (71.0%). The mean age was 39.91±19.15 years. The most common route of exposure was oral (99.3%). Most patients showed normal vital signs, oxygen saturation, and consciousness at the first presentation. The three most common clinical presentations were gastrointestinal (GI; 68.8%), cardiovascular (22.0%), and respiratory (13.8%) signs and symptoms. Most patients had normal blood chemistry laboratory results and chest X-ray findings at presentation. The median hospital stay was 2 days, and the mortality rate was 7%. Approximately 70% of patients underwent GI decontamination, including gastric lavage and a single dose of activated charcoal. In all, 31 patients were intubated and required ventilator support. Inotropic drugs were given to 4.2% of patients. Four moribund patients also received hyperinsulinemia–euglycemia therapy and intravenous hydrocortisone; however, all died. Patients who survived and died showed significant differences in age, duration from taking zinc phosphide to hospital presentation, abnormal vital signs at presentation (tachycardia, low blood pressure, and tachypnea), acidosis, hypernatremia, hyperkalemia, in-hospital acute kidney injury, in-hospital hypoglycemia, endotracheal tube intubation, and inotropic requirement during hospitalization (P<0.05). Conclusion Zinc phosphide poisoning causes fatalities. Most patients have mild symptoms, and GI symptoms are the most common. Patients who present with abnormal vital signs or

    Full Text Available Human rhinovirus (HRV is a leading cause of acute respiratory infection (ARI in young children and infants worldwide and has a high impact on morbidity and mortality in this population. Initially, HRV was classified into two species: HRV-A and HRV-B. Recently, a species called HRV-C and possibly another species, HRV-D, were identified. In Mexico, there is little information about the role of HRV as a cause of ARI, and the presence and importance of species such as HRV-C are not known. The aim of this study was to determine the clinical characteristics and genetic variability of HRV in Mexican children. Genetic characterization was carried out by phylogenetic analysis of the 5′-nontranslated region (5′-NTR of the HRV genome. The results show that the newly identified HRV-C is circulating in Mexican children more frequently than HRV-B but not as frequently as HRV-A, which was the most frequent species. Most of the cases of the three species of HRV were in children under 2 years of age, and all species were associated with very mild and moderate ARI.

    Chiropractic services have been delivered on station at select Veterans Health Administration (VHA) medical facilities since late 2004. No published data describing the characteristics of VHA chiropractic physicians (chiropractors) and chiropractic clinics exist at a national level. This study was designed to examine elements of the structures of chiropractic services in VHA settings. Web-based survey methods were used to question all chiropractors in VHA facilities (N = 36). Data were obtained from 33 providers, yielding a 91.6% response rate. Most respondents were full-time VHA employees, while others were part-time employees or contractors. Differences were found in prior training, integrated practice, and academic or research experience. Of the respondents, 88% ranked low back pain as the most common patient complaint seen in practice and 79% ranked cervical pain the second most common complaint. Of the new patient consultations, 67.6% originated from primary care, 9.4% from pain management, and 6.2% from physiatry. Most respondents were similar in their reported use of diagnostic and therapeutic procedures, but their reported rates of participation in various facility activities were different. Further work is needed for researchers and policy makers to more fully understand the integration and delivery of chiropractic services in VHA settings.

    The aim of this study was to review the epidemiological and clinical characteristics of neuromyelitis optica (NMO) and the immunopathological mechanisms involved in the neuronal damage. NMO is an inflammatory demyelinating autoimmune disease of the central nervous system that most commonly affects the optic nerves and spinal cord. NMO is thought to be more prevalent among non-Caucasians and where multiple sclerosis (MS) prevalence is low. NMO follows a relapsing course in more than 80-90% of cases, which is more commonly in women. It is a complex disease with an interaction between host genetic and environmental factors and the main immunological feature is the presence of anti-aquaporin 4 (AQP4) antibodies in a subset of patients. NMO is frequently associated with multiple other autoantibodies and there is a strong association between NMO with other systemic autoimmune diseases. AQP4-IgG can cause antibody-dependent cellular cytotoxicity (ADCC) when effector cells are present and complement-dependent cytotoxicity (CDC) when complement is present. Acute therapies, including corticosteroids and plasma exchange, are designed to minimize injury and accelerate recovery. Several aspects of NMO pathogenesis remain unclear. More advances in the understanding of NMO disease mechanisms are needed in order to identify more specific biomarkers to NMO diagnosis.

    Purpose: The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. Methods: A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed. The aim of this study is to describe the clinical, radiological, histological characteristics and the treatment of this tumor. Results: A total of nine patients were operated from January 01, 2000 to November 30, 2014. The average age of our patients was 51 years with ages that ranged from 29 to 65 with a male predominance. The period between onset of symptoms and diagnosis ranged from 24 months with an average 12 months. Posterior localization of the tumor was seen in all patients. Surgical resection was performed for all cases. The postoperative course has been satisfactory, with a complete recovery of neurological functions in all patients. Conclusions: The spinal epidural angiolipomas is rare expansive process causing spinal cord compression. Treatment is exclusively surgical resection. The functional outcome of spinal epidural angiolipomas is particularly favorable with a complete neurological recovery is if the patient was quickly operated. PMID:27695535

    Full Text Available Objective. 312 tinnitus sufferers were studied in order to analyze: the clinical characteristics of tinnitus; the presence of tinnitus-age correlation and tinnitus-hearing loss correlation; the impact of tinnitus on subjects' life and where possible the etiological/predisposing factors of tinnitus. Results. There is a slight predominance of males. The highest percentage of tinnitus results in the decades 61–70. Of the tinnitus sufferers, 197 (63.14% have a hearing deficit (light hearing loss in 37.18% of cases. The hearing impairment results of sensorineural type in 74.62% and limited to the high frequencies in 58.50%. The tinnitus is referred as unilateral in 59.93%, a pure tone in 66.99% and 10 dB above the hearing threshold in 37.7%. It is limited to high frequencies in 72.10% of the patients with sensorineural hearing loss (SNHL while the 88.37% of the patients with high-frequency SNHL have a high-pitched tinnitus (2=66.26;<.005. Conclusion. Hearing status and age represent the principal tinnitus related factors; there is a statistically significant association between high-pitched tinnitus and high-frequency SNHL. There is no significant correlation between tinnitus severity and tinnitus loudness confirming the possibility that neural connection involved in evoking tinnitus-related negative reactions are governed by conditioned reflexes.

    Ocular candidiasis is a major complication of Candida bloodstream infection (BSI). This study was performed to reveal the clinical characteristics of ocular candidiasis. Of the 220 patients with Candida BSI, 204 cases received ophthalmology consultations between January 2005 and December 2011 at 2 teaching hospitals. Fifty-four (26.5%) cases had findings consistent with the diagnosis of ocular candidiasis. Of these 54 cases, 43 (79.6%) were diagnosed within 7 days after a positive blood culture. Among ocular candidiasis cases, more cases were due to Candida albicans (P =0.034 odds ratio [OR]; 3.68 95% confidence interval [CI] 1.11-12.2) and had higher β-d-glucan values (P = 0.001 OR; 9.99 95% CI 2.60-21.3). We need to consider fundoscopic examination to be performed within the first 7 days of therapy, especially for those patients who have C. albicans BSIs and higher β-d-glucan values. Additionally, follow-up fundoscopic examination should be considered before stopping therapy for high-risk patients.

    AIM: To evaluate the clinical characteristics and progression of liver abscess caused by toxocara.METHODS: We retrospectively reviewed the medical records of patients with serum Ig G antibody to Toxocara canis and liver abscess diagnosed using abdominal computed tomography between February 2010 and February 2015. Among 84 patients exhibiting serum Ig G antibody to Toxocara canis, 34 patients were diagnosed with liver asbscess and treated with albendazole. A follow-up period of 1 year was conducted. RESULTS: Mean patient age was 53(34-79) years, with 26(76.5%) patients being male. Twenty-one(61.7%) patients were moderate or heavy drinkers, 23(67.6%) patients had a history of eating raw meat or liver and 6(17.6%) patients owned pet dogs or cats. Main patient symptoms consisted of right upper quadrant pain, fever, and fatigue; 18(52.9%) patients, however, presented with no symptoms. Lung involvement was detected in 444(11.7%) patients. The eosinophil count increased in 29(85.3%) patients at initial diagnosis, and decreased in most patients after albendazole treatment. The initial serum Ig E level increased in 25(73.5%) patients, but exhibited various response levels after albendazole treatment. Liver abscess formation improved in all patients.CONCLUSION: The liver abscess was improved with albendazole treatment.

    The aim of this study was to examine the clinical characteristics of patients with gender identity disorder (GID) at a GID clinic in Japan. A total of 603 consecutive patients were evaluated at the GID clinic using clinical information and results of physical and neurological examinations. Using DSM-IV criteria, 579 patients (96.0%) were diagnosed with GID. Four patients were excluded for transvestic fetishism, eight for homosexuality, five for schizophrenia, three for personality disorders, and four for other psychiatric disorders. Among the GID patients, 349 (60.3%) were the female-to-male (FTM) type, and 230 (39.7%) were the male-to-female (MTF) type. Almost all FTM-type GID patients started to feel discomfort with their sex before puberty and were sexually attracted to females. The proportion of FTM patients who had experienced marriage as a female was very low, and very few had children. Therefore, FTM-type GID patients seem to be highly homogeneous. On the other hand, various patterns of age at onset and sexual attraction existed among MTF patients. Among the MTF-type GID patients, 28.3% had married as males and 18.7% had sired children. Thus, MTF-type GID patients seem to be more heterogeneous.

    Gout is the most common form of inflammatory arthritis and it has an affliction to the foot. Foot involvement in gout has been linked to foot pain, impairment and disability. There has been limited research on the effect of ulceration on foot pain, impairment, disability and health-related quality of life in patients already living with gout. The aim of the study was to describe the wound characteristics and the effect on foot pain, disability and health-related quality of life in patients with foot ulceration associated with gout. Participants were recruited from rheumatology clinics in Auckland, New Zealand. All the current foot ulceration sites and wound characteristics were recorded using the TIME wound assessment tool. The outcome measures included general pain, patient global assessment scale, foot pain, disability and impairment. Participants completed the Cardiff Wound Impact Schedule to assess the effect of ulcers on health-related quality of life. Sensory loss, vibrational thresholds and ankle brachial pressure index were collated to assess for lower limb arterial disease. Six participants were predominantly older men with a long duration of gout, high rates of obesity and co-morbidities such as hypertension, hyperlipidaemia, diabetes and cardiovascular disease. The mean (SD) duration of the foot ulcers was 4 (2) months. The majority of foot ulcers observed were 0·5 cm(2) or smaller superficial thickness with surrounding callus. Partial thickness and full-thickness ulcers were also observed. Two patients presented with ulcers on multiple sites. There was only one case of infection. Gouty tophi were evident in most of the wounds. The dorsal aspect of the third toe was found to ulcerate in most cases. Moderate scores of foot pain, disability, impairment and health-related quality of life were observed. Most participants wore shoes deemed as poor. Foot ulceration in gout is chronic and multiple ulcers can occur with the potential of leading to delayed

    The purpose of this study was to estimate the general population lifetime and point prevalence of visual height intolerance and acrophobia, to define their clinical characteristics, and to determine their anxious and depressive comorbidities. A case-control study was conducted within a German population-based cross-sectional telephone survey. A representative sample of 2,012 individuals aged 14 and above was selected. Defined neurological conditions (migraine, Menière's disease, motion sickness), symptom pattern, age of first manifestation, precipitating height stimuli, course of illness, psychosocial impairment, and comorbidity patterns (anxiety conditions, depressive disorders according to DSM-IV-TR) for vHI and acrophobia were assessed. The lifetime prevalence of vHI was 28.5% (women 32.4%, men 24.5%). Initial attacks occurred predominantly (36%) in the second decade. A rapid generalization to other height stimuli and a chronic course of illness with at least moderate impairment were observed. A total of 22.5% of individuals with vHI experienced the intensity of panic attacks. The lifetime prevalence of acrophobia was 6.4% (women 8.6%, men 4.1%), and point prevalence was 2.0% (women 2.8%; men 1.1%). VHI and even more acrophobia were associated with high rates of comorbid anxious and depressive conditions. Migraine was both a significant predictor of later acrophobia and a significant consequence of previous acrophobia. VHI affects nearly a third of the general population; in more than 20% of these persons, vHI occasionally develops into panic attacks and in 6.4%, it escalates to acrophobia. Symptoms and degree of social impairment form a continuum of mild to seriously distressing conditions in susceptible subjects.

    Infiltrating lobular breast cancer (ILBC) is the most common special breast cancer subtype. This review provides a comprehensive description of ILBC characteristics, including epidemiology, clinical features, molecular genetics and histomorphology. Twenty detailed supplemental data tables guide through primary data of more than 200 original studies. Meta-analyses indicate that ILBC is at least twice as common in the Western world as it is in other geographic regions. ILBC is over-represented in so-called interval carcinomas and in primary metastatic breast cancer. ILBC is also associated higher age, higher pT stage and hormone receptor (ER/PR) positivity. Pathological complete response rates after neoadjuvant chemotherapy are low, ranging between 0% and 11%. Positive resection margins after breast-conserving surgery are comparatively frequent and 17% to 65% of patients undergo a second surgical intervention. Depending on the morphological stringency in the diagnosis of ILBC, lack of E-cadherin expression is observed in 55% to 100% of cases. CDH1/E-cadherin mutation detection rates vary between 12% and 83%. Various additional molecular factors, including PIK3CA, TP53, FOXA1, FGFR1, ZNF703 and BCAR4, have been implicated in ILBC or progression of lobular carcinoma in situ (LCIS) to invasive cancer and are discussed in detail. Eight instructive figure plates recapitulate the histomorphology of ILBC and its variants. Furthermore, we draw attention to rarely addressed histological details, such as two-sided nuclear compression and fat-avoiding growth at the invasion front. Last but not least, we discuss future translational research directions and emphasize the concept of synthetic lethality, which promises new options for targeted ILBC therapy.

    Female genital ulcer is a disease that affects a large number of women, and its etiologic diagnosis can be difficult. The disease may increase the risk of acquiring HIV. Genital ulcer may be present in sexually transmitted diseases (STD)--syphilis, chancroid, genital herpes, donovanosis, lymphogranuloma venereum; and other non-STD disorders (NSTD)--Behçet's syndrome, pemphigus, Crohn's disease, erosive lichen planus and others. This study evaluated the clinical-histopathologic-microbiologic characteristics of female genital ulcers. A cross-sectional descriptive prospective study was conducted during a six-month period to investigate the first 53 women without a definitive diagnosis, seeking medical care for genital ulcers at a genital infections outpatient facility in a university hospital. A detailed and specific history was taken, followed by a dermatologic and gynecologic examination. In addition to collecting material from the lesions for microbiologic study, a biopsy of the ulcer was performed for histopathologic investigation. The average age of the patients was 32.7 years, 56.6% had junior high school education and higher education. The most frequent etiology was herpetic lesion, followed by auto-immune ulcers. At the time of their first consultation, around 60% of the women were using inadequate medication that was inconsistent with the final diagnosis. Histologic diagnosis was conclusive in only 26.4% of the patients (14/53). Cure was obtained in 99% of the cases after proper therapy. The female genital ulcers studied were equally distributed between sexually transmitted and non-sexually transmitted causes. Herpes was the most frequent type of genital ulcer, affecting women indiscriminately, mostly between the ages of 20 and 40 years. The etiologic diagnosis of herpetic ulcers is difficult to make even when various diagnostic methods are applied. It is imperative that NSTD should be included in the differential diagnoses of female genital ulcers. The

    2011-11-01

    Leadership has been consistently implied in fostering clinical learning. However there is a lack of clarity about the form leadership should take. Limited quantitative research indicated a narrative approach to review literature from a broad perspective. A framework to guide the synthesis was developed to ensure a rigorous review process. Preliminary reading and review of papers using search terms nursing and leadership and clinical learning and learning culture narrowed the inclusion criteria to 245 papers published between 2000 and 2010. Given the diversity of the papers' focus, aim and context, a refined screening process justified the inclusion of twenty-six papers in the review. A critical appraisal of these peer-reviewed quantitative, qualitative and commentary papers identified factors/elements integral to effective leadership. Across the literature leadership was discussed in relation to two broad themes: influence of leadership on organisational learning and development and; influence of leadership on undergraduate clinical education. The factors central to leadership emerged as transformative principles, the role of the nurse unit/ward manager, collaboration and relationship building and role-modelling. The review has raised some suggestions for future research aimed at examining the impact of a leadership capacity building intervention that supports clinical learning.

    Hemifacial spasm (HFS) is a common neurological disorder characterized by involuntary tonic and clonic contractions of the muscles innervated by the facial nerve. We aimed to describe clinical features, common antecedents, triggers and relieving factors in patients with hemifacial spasm to study the correlation of hypertension and HFS, and to compare clinical features of primary and secondary cases of HFS. The data for the study were collected prospectively on a predesigned and pre-tested format at the first attendance in all consecutive HFS patients attending the movement disorders clinic of a tertiary teaching hospital in India. The demographic profile, HFS symptoms, antecedent illnesses and neurological examination were recorded and analyzed. Muscle power in individual muscles innervated by the facial nerve was tested carefully before botulinum toxin injection. Hemifacial spasm occurred in 7.14% (n = 582) of 8,151 cases registered at the movement disorders clinic from 1993 to 2010. Data of 321 patients were complete and were included in the study. Females constituted 49.22% (n = 158). The mean age the patients was 46.02 ± 11.82 years; ipsilateral ear clicking was observed in 22.74% cases. The most common aggravating factor was stress (44.86%), while the most common relieving factor was sleep (44.24%). Two hundred fifty-two patients (78.5%) had primary HFS. The severity of spasm correlated significantly with disease duration (p muscles (p < 0.001). We did not observe any correlation between HFS on the left side and hypertension, as has been reported earlier. This is one of the largest studies of HFS patients and the only one that prospectively assesses patients with HFS clinically on their first visit. Interesting observations of this study are lack of female preponderance, presence of clicking in the ipsilateral ear and facial weakness even prior to botulinum toxin injection.

    Purpose: To detect the presence of hypoxic tissue, which is known to increase the radioresistant phenotype, by its uptake of fluoromisonidazole (18F) (FMISO) using hybrid positron emission tomography/computed tomography (PET/CT) imaging, and to compare it with the glucose-avid tumor tissue imaged with fluorodeoxyglucose (18F) (FDG), in residual postsurgical skull base chordoma scheduled for radiotherapy. Patients and Methods: Seven patients with incompletely resected skull base chordomas were planned for high-dose radiotherapy (dose {>=}70 Gy). All 7 patients underwent FDG and FMISO PET/CT. Images were analyzed qualitatively by visual examination and semiquantitatively by computing the ratio of the maximal standardized uptake value (SUVmax) of the tumor and cerebellum (T/C R), with delineation of lesions on conventional imaging. Results: Of the eight lesion sites imaged with FDG PET/CT, only one was visible, whereas seven of nine lesions were visible on FMISO PET/CT. The median SUVmax in the tumor area was 2.8 g/mL (minimum 2.1; maximum 3.5) for FDG and 0.83 g/mL (minimum 0.3; maximum 1.2) for FMISO. The T/C R values ranged between 0.30 and 0.63 for FDG (median, 0.41) and between 0.75 and 2.20 for FMISO (median,1.59). FMISO T/C R >1 in six lesions suggested the presence of hypoxic tissue. There was no correlation between FMISO and FDG uptake in individual chordomas (r = 0.18, p = 0.7). Conclusion: FMISO PET/CT enables imaging of the hypoxic component in residual chordomas. In the future, it could help to better define boosted volumes for irradiation and to overcome the radioresistance of these lesions. No relationship was founded between hypoxia and glucose metabolism in these tumors after initial surgery.

    2006-01-01

    The term minimal hepatic encephalopathy (MHE) refers to the subtle changes in cognitive function, electrophysiological parameters, cerebral neurochemical/neurotransmitter homeostasis, cerebral blood flow, metabolism, and fluid homeostasis that can be observed in patients with cirrhosis who have no clinical evidence of hepatic encephalopathy; the prevalence is as high as 84% in patients with hepatic cirrhosis. This cirrhosis complication is generally not perceived by physician, and diagnosis can only be made by neuropsychological tests and other especial measurements like evoked potentials and image studies like positron emission tomography. Diagnosis of minimal hepatic encephalopathy may have prognostic and therapeutic implications in cirrhotic patients. The present review pretends to explore the clinic, therapeutic, diagnosis and prognostic aspects of this complication.

    Although pneumonia is associated with an increased risk of venous thromboembolism, patients with pulmonary embolism and concomitant pneumonia are uncommon. The aim of the present study was to investigate the clinical features of pulmonary embolism with coexisting pneumonia. We retrospectively compared clinical, radiologic and laboratory parameters between patients with pulmonary embolism and concomitant pneumonia (pneumonia group) and those with unprovoked pulmonary embolism (unprovoked group), and then between the pneumonia group and those with pulmonary infarction (infarction group). Of 794 patients with pulmonary embolism, 36 (5%) had coexisting pneumonia and six (1%) had no provoking factor other than pneumonia. Stroke was significantly more common in the pneumonia group, than either the unprovoked group or the infarction group. In the pneumonia group, fever was significantly more common and serum C-reactive protein levels were significantly higher. By contrast, central pulmonary embolism and right ventricular dilation on computed tomography were significantly less frequent in the pneumonia group. In addition, an adverse outcome due to pulmonary embolism was less common in the pneumonia group than in either of the other two groups. The coexistence of pulmonary embolism and pneumonia is rarely encountered in clinical practice, especially without the presence of other factors that could provoke venous thromboembolism and is commonly associated with stroke. It is characterized by lower incidences of central pulmonary embolism and right ventricular dilation and by a lower rate of adverse outcomes due to pulmonary embolism itself.

    2016-07-01

    Full Text Available Objectives: To clinically characterize women with hyperprolactinemia at InSer Pereira (Colombia and to determine the prevalence of prolactinoma. Methods: Retrospective description of 45 patients with hyperprolactinemia, and contrasted pituitary magnetic resonance (MR, between January 2008 and July 2013. Clinical manifestations, etiology, serum prolactin level, and MR findings were included. Results: The most frequent clinical manifestations were: infertility, galactorrhea, oligomenorrhea. There were 26 cases of prolactinoma (57.8 %, and 12 of idiopathic hyperprolactinemia (26.6 %. Out of the 26 prolactinomas, 23 were microadenomas (average size 5.1 mm; SD ± 3.2 mm. Average serum prolactin level was 74.05 ng/mL (SD ± 13.33 ng/mL. 78 % of patients with prolactinoma had serum prolactin level under 70.0 ng/mL. No significant association was found between serum prolactin level and the presence of prolactinoma. Conclusion: Prolactinomas are the main cause of hyperprolactinemia and they are found mostly with slight rise of serum prolactin. Pituitary MRI is recommended in patients with hyperprolactinemia, regardless of their prolactin level.

    2013-01-01

    Pituitary adenoma is the most common cause of hyperprolactinemia, which is a rare endocrine disorder encountered in pediatric patient care. Epidemiological and clinical information about hyperprolactinemia in childhood and adolescence is limited. Clinical signs of hyperprolactinemia are very heterogeneous. In girls, disturbances in menstrual function and galactorrhea may be seen, whereas in boys, headache, visual disturbances, delayed pubertal development and hypogonadism are often present. Owing to the ease of ordering a serum prolactin measurement, an evidence-based, cost-effective approach to the management of this endocrine disorder is required. Before a diagnosis of hyperprolactinemia is made, drug use, renal insufficiency, hypothyroidism, and parasellar tumors should be excluded. The main objectives of treatment are normalization of prolactin level, adenoma shrinkage, and recovery from clinical signs related to hyperprolactinemia. In patients with microadenoma, invasive or non-invasive macroadenoma, and even in patients with visual field defects, dopamine agonists are the first-line treatment. Surgical treatment is indicated in patients who are unresponsive or intolerant to medical treatment or who have persistent neurological signs. Radiotherapy should be considered as a supportive treatment for patients in whom surgery fails or medical response is not achieved.

    2016-01-01

    Background Inadequate epidemiologic investigations of the paranasal sinuses malignancies prompted this retrospective study with special emphasis on a major group of 111 tumors. Material and Methods Clinical records of 111 patients with histologically confirmed malignant tumors of the paranasal sinuses were investigated retrospectively from April 2000 to January 2012. Collection of data included demographic information, clinical manifestations, treatment plans, and histopathology of the tumor. Results There were 69 (62.16%) male and 42 (37.83%) female patients (male-to-female ratio of 1.6:1), with a median age of 49±12.2 years (range 21 to 88 years). A high level of occurrence was noticed in the fifth (26.3%) decade of life. The most frequent histological types were squamous cell carcinoma (43.5%) and adenoid cystic carcinoma (19%). Among clinical manifestations, nasal obstruction was the most frequent followed by diplopia, and facial swelling. Fifty three patients (47.74%) were treated with combined approach of surgery and radiation therapy. Conclusions Paranasal sinuses malignancies are rare conditions with nonspecific symptoms which make early diagnosis of the lesions more challenging. The optimal therapeutic protocol for patients suffering from these tumors is still a somewhat controversial entity and requires further studies. Key words:Paranasal sinuses, malignancy, surgery,radiotherapy. PMID:27475693

    Objective Mutations in the LMNA gene encoding lamins A and C of the nuclear lamina are a frequent cause of cardiomyopathy accounting for 5–8% of familial dilated cardiomyopathy (DCM). Our aim was to study disease onset, presentation and progression among LMNA mutation carriers. Methods Clinical follow-up data from 27 LMNA mutation carriers and 78 patients with idiopathic DCM without an LMNA mutation were collected. In addition, ECG data were collected and analysed systematically from 20 healthy controls. Results Kaplan-Meier analysis revealed no difference in event-free survival (death, heart transplant, resuscitation and appropriate implantable cardioverter-defibrillator therapy included as events) between LMNA mutation carriers and DCM controls (p=0.5). LMNA mutation carriers presented with atrial fibrillation at a younger age than the DCM controls (47 vs 57 years, p=0.003). Male LMNA mutation carriers presented with clinical manifestations roughly a decade earlier than females. In close follow-up non-sustained ventricular tachycardia was detected in 78% of LMNA mutation carriers. ECG signs of septal remodelling were present in 81% of the LMNA mutation carriers, 21% of the DCM controls and none of the healthy controls giving a high sensitivity and specificity for the standard ECG in distinguishing LMNA mutation carriers from patients with DCM and healthy controls. Conclusions Male LMNA mutation carriers present clinical manifestations at a younger age than females. ECG septal remodelling appears to distinguish LMNA mutation carriers from healthy controls and patients with DCM without LMNA mutations. PMID:28123761

    Cardiomyopathies are diseases of the heart muscle, a term introduced in 1957 to identify a group of myocardial diseases not attributable to coronary artery disease. The definition has since been modified to refer to structural and or functional abnormalities of the myocardium where other known causes of myocardial dysfunction, such as systemic hypertension, valvular disease and ischemic heart disease, have been excluded. In this review, we discuss the pathophysiology, clinical assessment and therapeutic strategies for hypertrophic, dilated and hypertrophic cardiomyopathies, with a particular focus on aspects unique to children.

Characteristic behavioral disturbances in PWS include excessive interest in food, skin picking, difficulty with a change in routine, temper tantrums, obsessive and compulsive behaviors, and mood fluctuations. Individuals with PWS typically have intellectual disabilities (borderline to mild/moderate mental retardation and exhibit a higher overall behavior disturbance compared to individuals with similar intellectual disability. Due to its multisystem disorder, family members, caregivers, physicians, dieticians, and speech-language pathologists all play an important role in the management and treatment of symptoms in an individual with PWS. This article reviews current research on behavior and cognition in PWS and discusses management guidelines for this disorder.Keywords: Prader–Willi syndrome; neurodevelopment, hyperphagia, disability

    Full Text Available Background: Polycystic ovary syndrome (PCOS is common diagnosis in women presenting with infertility. All the dimensions of PCOS have not been completely explored. Many studies have tried to characterize the exact presentation of the disease. In this study we studied clinical features of PCOS in Indian women to characterize different phenotypes of this syndrome. Prevalence of acanthosis nigricans (AN as surrogate marker of insulin resistance, obesity, hirsutism and hypothyroidism in PCOS women have been simultaneously studied. Materials and Methods: Present work is a non comparative cross-sectional open label study carried out over a period of 18 months in an endocrinology hospital in western Maharashtra, India. Results and Conclusion: Authors conclude that PCOS occurs both in obese and non-obese women; AN and hirsutism occur in equal proportion of patients. AN is correlated with obesity. Hormonal dysfunctions in PCOS manifested together or independently. PCOS women can be sub grouped based on clinical features suggestive of endocrinological malfunctions and can be investigated accordingly for selection of appropriate treatment modalities.

    A clinical-electroneuromyographical study of 40 children (32 (80%) of them aged from 12 to 17 years, mean age 13,9+/-1,8 years, and 8 (20%) - from 1 to 8 years, mean age 4,4+/-2,1 years) were studied in the acute period of facial nerve paralysis (FNP). Six (15%) children had FNP in the anamnesis. Among precipitating factors were the cold exposure the day before disease onset (20 (50%) patients), symptoms of flu (13 (32,5%) patients) and psycho-emotional tension (3 (7,5%) patients). No precipitation was noted in 4 (10%) children. The degree of muscle paresis was 81,9+/-7% that corresponded to clinical stages III-IV according to K. Rosler. An electroneuromyographical analysis of motor ortho- and antidromic response to the facial nerve stimulation on the side of paresis and on the contralateral side in patients and controls revealed the presence of proximal axon- and myelinopathy of facial nerve with the involvement of its own motorneurons and brain stem interneurons. The maintenance of wink reflex and F-wave blocks in the period over 3 weeks are prognostically unfavorable factors for restoration of mimic muscle function in the early stage of disease.

    PAPA syndrome (Pyogenic Arthritis, Pyoderma gangrenosum, and Acne) is an autosomal dominant, hereditary auto-inflammatory disease arising from mutations in the PSTPIP1/CD2BP1 gene on chromosome 15q. These mutations produce a hyper-phosphorylated PSTPIP1 protein and alter its participation in activation of the "inflammasome" involved in interleukin-1 (IL-1β) production. Overproduction of IL-1β is a clear molecular feature of PAPA syndrome. Ongoing research is implicating other biochemical pathways that may be relevant to the distinct pyogenic inflammation of the skin and joints characteristic of this disease. This review summarizes the recent and rapidly accumulating knowledge on these molecular aspects of PAPA syndrome and related disorders.

    The incidence of fetal tumors has been increased due to generalization of prenatal evaluation and improvement of imaging techniques. The early detection of a fetal tumor and understanding of its imaging features are very important for fetal, maternal, and neonatal care. Ultrasonography is usually used for the detection and differential diagnosis of fetal tumors, and magnetic resonance imaging is increasingly being used as a complementary study. Many fetal tumors have different clinical and imaging features compared with pediatric tumors. Although several fetal tumors may mimic other common anomalies, some specific imaging features may carry early accurate diagnosis of fetal tumors, which may alter the prenatal management of a pregnancy and the mode of delivery, and facilitate immediate postnatal treatment.

    Benign osteoblastoma is a rare, vascular, osteoid-forming bone tumor that occurs even less frequently in the cranial bones. Benign osteoblastoma of the cranium affects women slightly more often than men and typically presents in the first three decades of life. Although clinical presentation can vary depending on location, cranial osteoblastoma usually presents as a painful, non-mobile, subcutaneous mass or swelling. On CT scan, it generally presents as a well-demarcated, mixed lytic and sclerotic lesion, with enlarged diploe, thinning outer and/or inner tables, and varying degrees of calcification. It is hypo to isointense on T1-weighted MRI and has variable presentation on T2-weighted MRI. Gross total resection is the definitive treatment, while subtotal resection is utilized when it is necessary to preserve critical adjacent neurovascular structures.

    A 9-month-old male infant was admitted to our hospital on the second day of cold like syndrome because of high fever, convulsion, coma, and decerebrate rigidity. Serum GOT, GPT, LDH, and CPK were markedly elevated. Serum ammonia was slightly increased, and hypoglycemia was present. The cerebrospinal fluid showed no pleocytosis, normal sugar content, but increased protein. Thus we made a diagnosis of clinical Reye syndrome according to the criteria by Yamashita, et al. A CT on the day of admission showed symmetrical low-density areas in the posterior fossa and the regions of thalamus. Ringed enhancements were seen around the areas of low density in the thalamus on the twenty-second hospital day. We consider that these lesions may represent the infarction due to obstruction of the thalamoperforant arteries caused by cerebral edema in the early stage of the disease.

    Full Text Available Background: End-stage hypertrophic cardiomyopathy (HCM is complicated by substantial adverse events. However, few studies have focused on electrocardiographic features and their prognostic values in HCM. This study aimed to evaluate the clinical manifestations and prognostic value of electrocardiography in patients with end-stage HCM. Methods: End-stage HCM patients were enrolled from a total of 1844 consecutive HCM patients from April 2002 to November 2013 at Fuwai Hospital. Clinical data, including medical history, electrocardiography, and echocardiography, were analyzed. Cox hazards regression analysis was used to assess the risk factors for cardiovascular mortality. Results: End-stage HCM was identified in 99 (5.4% patients, averaged at 52 ± 16 years old at entry. Atrial fibrillation was observed in 53 patients and mural thrombus in 19 patients. During 3.9 ± 3.0 years of follow-up, embolic stroke, refractory heart failure, and death or transplantation were observed in 20, 39, and 51 patients, respectively. The incidence of annual mortality was 13.2%. Multivariate Cox hazards regression analysis identified New York Heart Association Class (NYHA III/IV at entry (hazard ratio [HR]: 1.99; 95% confidence interval [CI]: 1.05-3.80; P = 0.036, left bundle branch block (LBBB (HR: 2.80; 95% CI: 1.47-5.31; P = 0.002, and an abnormal Q wave (HR: 2.21; 95% CI: 1.16-4.23; P = 0.016 as independent predictors of cardiovascular death, in accordance with all-cause death and heart failure-related death. Conclusions: LBBB and an abnormal Q wave are risk factors of cardiovascular mortality in end-stage HCM and provide new evidence for early intervention. Susceptibility of end-stage HCM patients to mural thrombus and embolic events warrants further attention.

Brucellosis is met everywhere on all continents of the world, especially in the countries where livestock sector is developed. Nowadays in spite of significant success in the struggle against brucellosis this infection is a social problem. Brucellosis has specific clinical manifestations during various age periods. Problems interrelated with the study of the pathogenesis of brucellosis infection, particularly immune genesis, defining the progress and the outcome of the disease have great importance. Object of the research: to study peculiarities of the progress of acute brucellosis in children taking into account clinical-immunologic data. Materials and methods of the research: the research was based on the results of examinations of 23 children from 3 to 14 years old with brucellosis mostly living in endemic foci of the Republic of Uzbekistan. The diagnosis was defined based on epidemiologic anamnesis, clinical symptoms and laboratory data. All examined children got the analysis of detailed blood immunogramm. The corresponding data of 20 healthy children served to be controlling ones. Results and discussion: The analysis of epidemiologic anamnesis showed, that 78.3% of the examined patients with brucellosis were villagers keeping sheep, goats and cattle. In 73.9% cases source of infection was sheep and goats, 8.7% - cattle, and in 17.4% cases we could observe mixed type of infection. 78% of patients applied to hospital during prodromal period. Main complaints were weakness, frustration, headache, fatigue, bad appetite.

A good response group (GRG and a poor response group (PRG were defined if the duration of their seizure-free period was >1 year, or <1 year, respectively.Results: There were 46 (54.8% patients in the GRG and 38 (45.2% patients in the PRG. The number of antiepileptic drugs administered was significantly lower in the GRG than that in the PRG (1.3±0.8 vs 2.8±1.0, respectively; P<0.05. The GRG had a significantly older age of onset than the PRG and a lower occurrence of initial precipitating events, such as febrile seizures, central nervous system infection, and head trauma (P<0.05. The prevalence of EEG abnormality, presence of aura, generalized seizures, and automatism was less frequently observed in the GRG (P<0.05. Multivariate analysis showed that the presence of automatism and initial precipitating events were significantly associated with a poor prognosis (P<0.05.Conclusion: In contrast to the commonly assumed intractability of TLE, we found that more than 54% of patients with TLE-NL achieved a long seizure-free period. Older age at onset of TLE-NL was associated with a better prognosis. However, the presence of automatism and initial precipitating events were related to a poor prognosis. Future prospective

    Full Text Available We performed a prospective, double-blinded study in 20 patients undergoing gynecologic surgery with lower abdominal incision, to investigate characteristics of intrathecal hyperbaric levobupivacaine compared with isobaric levobupivacaine. We randomly assigned them to receive 3 mL of either isobaric or hyperbaric 0.42% levobupivacaine intrathecally. We found that hyperbaric levobupivacaine, compared with isobaric levobupivacaine, spread faster to T10 level (2.8 ± 1.1 versus 6.6 ± 4.7 minutes, =0.039, reached higher sensory block levels at 5 and 15 minutes after injection (T8 versus L1, =0.011, and T4 versus T7, =0.027, resp., and had a higher peak level (T4 versus T8, =0.040. Isobaric levobupivacaine caused a wider range of peak levels (L1 to C8 compared with hyperbaric form (T7 to T2. The level of T4 or higher reached 90% in the hyperbaric group compared with 20% in the isobaric group (=0.005. Our results suggest that hyperbaric levobupivacaine was more predictable for sensory block level and more effective for surgical procedures with lower abdominal approach. Hyperbaric levobupivacaine seems to be suitable, but the optimal dosage needs further investigation.

    Full Text Available Purpose : Turner syndrome (TS is a disorder in which various anomalies can be accompanied, especially cardiovascular, renal, thyroid and auditory problems. The aim of this study is to identify the incidence of these disorders in patients with TS according to karyotype. Methods : We reviewed medical records of 90 patients with TS diagnosed by chromosomal analysis in 4 hospitals from Jan 1998 to Dec 2007. We evaluated these cases by prepared protocol of 4 medical problems. Results : The distribution of karyotype was 45,X (47.8%, mosaic pattern (34.4% and structural aberration group (17.8 %. Renal anomalies, cardiovascular anomalies, thyroid disorders and auditory problems are accompanied in 4.4%, 10.0 %, 11.1% and 5.6%, respectively. 45,X group had renal anomalies (7.0%, cardiovascular anomalies (18.6%, thyroid disorders (9.3% and auditory problems (11.6%. Mosaic group had renal anomalies (3.2%, thyroid disorders (12.9%, no cardiovascular anomalies and auditory problems. Structural aberration group had cardiovascular anomalies (6.3%, thyroid disorders (12.5% and no other 2 problems. Patients with 45,X group had a significant higher incidence of cardiovascular anomalies (P=0.025. Conclusion : Our results indicate that there are differences clinically according to karyotype of TS, especially in incidence of cardiovascular anomalies.

    Full Text Available Mohammed A ZolalyDepartment of Pediatrics, College of Medicine, Taibah University, Al-Madinah Al-Munawarah, Kingdom of Saudi ArabiaBackground: The purpose of this study was to determine whether seizure susceptibility due to antihistamines is provoked in patients with febrile seizures.Methods: The current descriptive study was carried out from April 2009 to February 2011 in 250 infants and children who visited the Madinah Maternity and Children's Hospital as a result of febrile convulsions. They were divided into two groups according to administration of antihistamines at the onset of fever.Results: Detailed clinical manifestations were compared between patients with and without administration of antihistamines. The time from fever detection to seizure onset was significantly shorter in the antihistamine group than that in the nonantihistamine group, and the duration of seizures was significantly longer in the antihistamine group than in the nonantihistamine group. No significant difference was found in time from fever detection to seizure onset or seizure duration between patients who received a first-generation antihistamine and those who received a second-generation antihistamine.Conclusion: Due to their central nervous system effects, H1 antagonists should not be administered to patients with febrile seizures and epilepsy. Caution should be exercised regarding the use of histamine H1 antagonists in young infants, because these drugs could potentially disturb the anticonvulsive central histaminergic system.Keywords: antihistamine, nonantihistamine, histamine H1 antagonist, febrile seizures

  13. Clinical characteristics and current therapies for inherited retinal degenerations.

    2014-10-16

    Inherited retinal degenerations (IRDs) encompass a large group of clinically and genetically heterogeneous diseases that affect approximately 1 in 3000 people (>2 million people worldwide) (Bessant DA, Ali RR, Bhattacharya SS. 2001. Molecular genetics and prospects for therapy of the inherited retinal dystrophies. Curr Opin Genet Dev 11: 307-316.). IRDs may be inherited as Mendelian traits or through mitochondrial DNA, and may affect the entire retina (e.g., rod-cone dystrophy, also known as retinitis pigmentosa, cone dystrophy, cone-rod dystrophy, choroideremia, Usher syndrome, and Bardet-Bidel syndrome) or be restricted to the macula (e.g., Stargardt disease, Best disease, and Sorsby fundus dystrophy), ultimately leading to blindness. IRDs are a major cause of severe vision loss, with profound impact on patients and society. Although IRDs remain untreatable today, significant progress toward therapeutic strategies for IRDs has marked the past two decades. This progress has been based on better understanding of the pathophysiological pathways of these diseases and on technological advances.

    Tangier disease (TD) (OMIM#205400) is a rare autosomal recessive disorder resulting from mutations in the ABCA1 gene, leading to decreased levels of plasma high-density lipoproteins (HDL). Peripheral neuropathy is a common finding in this disease, and may present as relapsing/remitting mono/polyneuropathies or as syringomyelia-like neuropathy. We retrospectively analyzed four patients, and report here their clinical, biological, electrophysiological, imaging, and genetic findings. Three patients had a typical pseudosyringomyelic neuropathy including facial diplegia, but asymmetrical onset was observed in one patient who had first been misdiagnosed with Lewis-Sumner syndrome. Electrophysiological pattern was heterogeneous, showing both signs of demyelination and axonal degeneration. Truncating mutations of the ABCA1 gene, including two previously undescribed mutations, were constantly found. Atypical symptom onset and demyelinating features on electrophysiological examination can be misleading in case of pseudosyringomyelic neuropathy. These reports illustrate two different neurological phenotypes in TD, namely the pseudosyringomyelic type and the Lewis-Sumner-like type, and advocate for a systematic assessment of lipid profile including HDL cholesterol in demyelinating neuropathies.

    2012-01-01

    The present study had three objectives: (a) to characterize the functional capacity of patients with PD, (b) to assess the relationship between the physical fitness components of functional capacity with clinical characteristics and disease severity, and (c) to compare the physical fitness components of functional capacity with clinical characteristics according to disease severity. The study included 54 patients with idiopathic PD who were distributed into two groups according to PD severity: unilateral group (n=35); and bilateral group (n=19). All patients underwent psychiatric assessment by means of the Hoehn and Yahr (HY) staging of PD, the Unified Parkinson's Disease Rating Scale (UPDRS), the Hospital Anxiety and Depression Scale (HADS-A and HADS-D, respectively), and The Mini-Mental State Examination (MMSE). The physical fitness components of functional capacity were evaluated over a 2-day period, using recommendations by the American Alliance for Health, Physical Education, Recreation and Dance, and the Berg Balance Scale (BBS). Pearson correlation coefficients and multiple regressions were calculated to test the correlation between functional capacity and clinical characteristics, and to predict clinical scores from physical performance, respectively. Clinical variables and physical component data were compared between groups using analysis of variance to determine the effects of disease severity. Patients with advanced disease showed low levels of functional capacity. Interestingly, patients with good functional capacity in one of the physical fitness components also showed good capacities in the other components. Disease severity is a major factor affecting functional capacity and clinical characteristics. Medical providers should take disease severity into consideration when prescribing physical activity for PD patients, since the relationship between functional capacity and clinical characteristics is dependent on disease severity.

    2011-01-01

    Natural language processing (NLP) has become crucial in unlocking information stored in free text, from both clinical notes and biomedical literature. Clinical notes convey clinical information related to individual patient health care, while biomedical literature communicates scientific findings. This work focuses on semantic characterization of texts at an enterprise scale, comparing and contrasting the two domains and their NLP approaches. We analyzed the empirical distributional characteristics of NLP-discovered named entities in Mayo Clinic clinical notes from 2001-2010, and in the 2011 MetaMapped Medline Baseline. We give qualitative and quantitative measures of domain similarity and point to the feasibility of transferring resources and techniques. An important by-product for this study is the development of a weighted ontology for each domain, which gives distributional semantic information that may be used to improve NLP applications.

    To investigate the difference of biochemical characteristics on gsp-positive and gsp-negative growth hormone (GH)-secreting pituitary tumors, 18 GH-secreting pituitary tumors were examined for their clinical characteristics and gsp oncogenes. All patients received the pituitary function combinative stimulating test. It was found that there were no difference in the sex, age, tumor size, course of disease and plasma basal GH levels with gsp- positive and gsp-negative patients. The plasma levels of PRL were increased in most patients (11/18), and the plasma levels of TSH in gsp-positive patients were higher than those in gsp-negative patients (P<0.05). There was no significant difference in the responses to pituitary combinative stimulating test in gsp-positive and gsp-negative patients. It was concluded that there was little difference in the clinical biochemical characteristics of gsp-positive with gsp-negative GH-secreting pituitary tumors.

    Tiago Machado Guerreiro

    2010-12-01

    Full Text Available Restless legs syndrome (RLS is a neurological disorder that responds to dopaminergic drugs, indicating a common pathophysiology with Parkinson's disease (PD. The prevalence of RLS was estimated in a group of PD patients and its clinical and biochemical characteristics were analysed. Forty-eight patients with PD were evaluated into two groups, with and without RLS. Clinical characteristics assessed in both groups were age, gender, duration of PD, Hoehn and Yahr, and Schwab and England scales. Laboratory variables such as hemoglobin, s-iron, s-ferritin and creatinine were obtained. The prevalence of RLS was 18.75%. No significant differences regarding clinical variables and biochemical parameters were observed. The high prevalence of RLS found in PD patients suggests the concept of a common etiological link and it seems that secondary causes did not play a central role in the pathophysiology of RLS in this group of parkinsonian patients.

    Intervertebral disc degeneration proceeds with age and is one of the major causes of lumbar pain and degenerative lumbar spine diseases. However, studies in the field of intervertebral disc biology have been hampered by the lack of reliable cell lines that can be used for in vitro assays. In this study, we show that a chordoma-derived cell line U-CH1-N cells highly express the nucleus pulposus (NP) marker genes, including T (encodes T brachyury transcription factor), KRT19, and CD24. These observations were further confirmed by immunocytochemistry and flow cytometry. Reporter analyses showed that transcriptional activity of T was enhanced in U-CH1-N cells. Chondrogenic capacity of U-CH1-N cells was verified by evaluating the expression of extracellular matrix (ECM) genes and Alcian blue staining. Of note, we found that proliferation and synthesis of chondrogenic ECM proteins were largely dependent on T in U-CH1-N cells. In accordance, knockdown of the T transcripts suppressed the expression of PCNA, a gene essential for DNA replication, and SOX5 and SOX6, the master regulators of chondrogenesis. On the other hand, the CD24-silenced cells showed no reduction in the mRNA expression level of the chondrogenic ECM genes. These results suggest that U-CH1-N shares important biological properties with notochordal NP cells and that T plays crucial roles in maintaining the notochordal NP cell-like phenotype in this cell line. Taken together, our data indicate that U-CH1-N may serve as a useful tool in studying the biology of intervertebral disc. © 2016 The Authors.

    Schizophrenia (SCH) is a complex, psychiatric disorder affecting 1 % of population. Its clinical phenotype is heterogeneous with delusions, hallucinations, depression, disorganized behaviour and negative symptoms. Bipolar affective disorder (BD) refers to periodic changes in mood and activity from depression to mania. It affects 0.5-1.5 % of population. Two types of disorder (type I and type II) are distinguished by severity of mania episodes. In our analysis, we aimed to check if clinical and demographical characteristics of the sample are predictors of symptom dimensions occurrence in BD and SCH cases. We included total sample of 443 bipolar and 439 schizophrenia patients. Diagnosis was based on DSM-IV criteria using Structured Clinical Interview for DSM-IV. We applied regression models to analyse associations between clinical and demographical traits from OPCRIT and symptom dimensions. We used previously computed dimensions of schizophrenia and bipolar affective disorder as quantitative traits for regression models. Male gender seemed protective factor for depression dimension in schizophrenia and bipolar disorder sample. Presence of definite psychosocial stressor prior disease seemed risk factor for depressive and suicidal domain in BD and SCH. OPCRIT items describing premorbid functioning seemed related with depression, positive and disorganised dimensions in schizophrenia and psychotic in BD. We proved clinical and demographical characteristics of the sample are predictors of symptom dimensions of schizophrenia and bipolar disorder. We also saw relation between clinical dimensions and course of disorder and impairment during disorder.

    To determine whether the presence of melancholic features in hospitalized patients with major depressive disorder (MDD) was associated with specific clinical characteristics and treatment outcomes, supporting melancholic depression as a distinct subtype within MDD. 126 acutely ill inpatients with MDD were enrolled in an open, 6-week trial with fixed-dose fluoxetine 20mg daily. Symptom severity was assessed regularly, using the 17-item Hamilton Depression Rating Scale (HAMD-17) and Clinical Global Impression of Severity (CGI-S). Melancholic features were defined according to the DSM-IV criteria. Clinical variables were compared between patients with and without melancholic features. Generalized estimating equations method was used to explore the differences in HAMD-17 and CGI-S scores between the 2 groups over time. Clinical response was defined as having a 50% or greater reduction in HAMD-17 scores. 96 (76.2%) of the 126 patients with at least one post-baseline assessment met the criteria for melancholic depression. Melancholic depression differed from non-melancholic depression in clinical characteristics and predicted a better response to fluoxetine treatment. The differentiation between melancholic and non-melancholic depression within MDD hence is clinically significant and valid.

    A retrospective cross-sectional study using data from an outpatient clinic in China was conducted to investigate the clinical features of early-onset gout patients.All patients diagnosed with gout were asked about clinical characteristics of their gout and comorbid diseases. Patients presenting with acute flares were asked about common triggers before the flare. "Early-onset" gout was defined as onset of gout before 40 years and "late-onset" as onset ≥40 years. Major joint involvement, flare frequency before presentation, the cumulative number of involved joints, proportions of tophi complications at presentation, flare triggers, as well as any metabolic, cardiovascular, cerebrovascular, and renal comorbidities, were compared between the 2 groups.A total of 778 gout patients were enrolled in this study, including 449 (57.7%) in the early-onset group and 329 (42.3%) in the late-onset group. Compared with the late-onset gout patients, the early-onset gout patients had a higher proportion of ankle/mid-foot involvement (62.8% vs 48.2%, P gout patients had fewer metabolic, cardiovascular, cerebrovascular, or renal complications.Early- and late-onset gout patients had different clinical features. Early-onset seems to be influenced more by lifestyle, while late-onset patients have more complications because of comorbidities.

    This study examines the relationship between job characteristics and job outcomes of pharmacists in hospital, clinic, and community pharmacies in Taiwan. The structured questionnaires covered the items of job characteristics, job outcomes, and demographics of pharmacists, and were distributed between Feb 2004 and April 2004. Two hundred and ninety-eight pharmacists responded. Data were analyzed descriptively, and univariate analyses, factor analysis, and multiple regression analyses were used. It found the more enriched the job, the greater the job satisfaction and less intention to leave. And community pharmacists reported greater job enrichment and job satisfaction and less intention to leave than did hospital and clinic pharmacists. It suggests pharmacy managers could recognize the needs of pharmacists to redesign and enrich their work arrangements.

    Viral meningitis is the most common cause of aseptic meningitis. Use of the polymerase chain reaction (PCR) has increased the ability to determine the etiology of viral meningitis. This study used PCR analysis to evaluate the etiology of aseptic meningitis in 177 previously healthy adults over a 5-year period, as well as analyzing the clinical characteristics, cerebrospinal fluid (CSF) findings, and prognosis according to each etiology. The most frequent cause of aseptic meningitis was enterovirus (EV), followed by varicella zoster virus (VZV). Patients with EV meningitis were significantly younger than those with VZV meningitis. The percentage of lymphocytes in white blood cell counts and protein concentrations in the CSF differed significantly among patients with EV, VZV and meningitis of undetermined etiology. Younger age and lower percentage of lymphocyte and protein level in CSF analysis may be suggestive of EV meningitis. Further prospective studies are warranted to identify the correlations between the clinical characteristics and the etiologies of meningitis.

    The aim of this study was to investigate the clinical and laboratorial characteristics of splenic marginal zone lymphoma (SMZL) with an abnormal complete blood count (CBC). Data of 19 newly diagnosed SMZL patients with abnormal CBC were analyzed retrospectively. Seven patients were diagnosed by using splenic histology, 12 patients who did not undergo splenectomy were diagnosed on the basis of typical clinical presentation and cytologic, immunophenotypic and histologic characteristics of peripheral blood and bone marrow, according to SBLG guidelines. The results showed that leukocytosis (≥ 10.0×10(9)/L) was seen in 5 cases (26.3%); leukocytopenia (complete response was achieved in 9 out of 11 (81.8%) patients. It is concluded that SMZL with abnormal CBC has a higher incidence of cytopenia, bone marrow involvement and autoimmune phenomena. Therapeutic strategies consisting of Rituximab show a better efficacy.

    Full Text Available Context An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor which was first described by Adsay et al. in 1996. It has been defined as a new subgroup of IPMN. Case report We report the case of a 76-year-old woman who presented with nausea. Imaging studies revealed a cystic mass in the body of the pancreas. She underwent a successful distal pancreatectomy and splenectomy, and has subsequently remained well. Microscopically, the cyst was lined by columnar epithelium similar to pancreatic duct epithelium, and the nodular projection consisted of arborizing papillary structures, lined by plump cells with abundant eosinophilic cytoplasm. These eosinophilic cells were immunohistochemically positively stained with anti-mitochondrial antibody. The cellular atypism was mild and the proliferating index was low, compatible with adenoma of an intraductal oncocytic papillary neoplasm. Although no ovarian type stroma was identified, in our case, no communication to main pancreatic duct (located in the pancreatic body and rapid growth by intracystic hemorrhage were clinical characteristics of a mucinous cystic neoplasm, but not IPMN. Conclusion With only 17 cases reported to date, the clinical and pathological details of an intraductal oncocytic papillary neoplasm are still unclear. We herein add one case with different characteristics from those of the past reports. To our knowledge, this is the first case report of an intraductal oncocytic papillary neoplasm with the clinical characteristics of a mucinous cystic neoplasm.

    Background Spontaneous attack of variant angina (VA) is a unique component of coronary artery disease (CAD), and associated with severe cardiac events. However, no data are available regarding sex differences in Chinese patients with spontaneous attacks of VA. Accordingly, the present retrospective study was initiated to evaluate the Clinical characteristics of Chinese female patients with spontaneous attacks of VA.Methods From January 2003 to January 2008, a total of 209 patients were diagnosed to have had a spontaneous attack of VA at Fu Wai Hospital. Of them, 27 were female, and their clinical findings were collected and compared with male patients for aspects of risk factors, clinical features and angiographical findings.Results Spontaneous attacks of VA was relatively uncommon in female (12.9%) compared with male patients. The female patients were less likely to have a history of smoking (14.8% vs. 79.7%, P <0.001), more likely to have a family history of CAD (33.3% vs. 11.0%, P<0.01), and to have had a greater incidence of ventricular fibrillation during attack (11.1% vs. 2.2%, P<0.05). There were no significant differences in other characteristics between the two groups.Conclusion Chinese female patients who experienced a spontaneous attack of VA had the characteristics of less smoking history, more family history of CAD and higher occurrence of ventricular fibrillation than male patients.

    The objective of this article was to record reporting characteristics related to study quality of research published in major specialty dental journals with the highest impact factor (Journal of Endodontics, Journal of Oral and Maxillofacial Surgery, American Journal of Orthodontics and Dentofacial Orthopedics; Pediatric Dentistry, Journal of Clinical Periodontology, and International Journal of Prosthetic Dentistry). The included articles were classified into the following 3 broad subject categories: (1) cross-sectional (snap-shot), (2) observational, and (3) interventional. Multinomial logistic regression was conducted for effect estimation using the journal as the response and randomization, sample calculation, confounding discussed, multivariate analysis, effect measurement, and confidence intervals as the explanatory variables. The results showed that cross-sectional studies were the dominant design (55%), whereas observational investigations accounted for 13%, and interventions/clinical trials for 32%. Reporting on quality characteristics was low for all variables: random allocation (15%), sample size calculation (7%), confounding issues/possible confounders (38%), effect measurements (16%), and multivariate analysis (21%). Eighty-four percent of the published articles reported a statistically significant main finding and only 13% presented confidence intervals. The Journal of Clinical Periodontology showed the highest probability of including quality characteristics in reporting results among all dental journals.

    2016-07-01

    Full Text Available Idiopathic inflammatory myopathies (IIM are traditionally identified as a group of disorders that target skeletal muscle due to autoimmune dysfunction. The IIM can be divided into subtypes based on certain clinical characteristics, and several classification schemes have been proposed. The predominant diagnostic criteria for IIM is the Bohan and Peter criteria, which subdivides IIM into primary polymyositis (PM, primary dermatomyositis (DM, myositis with another connective tissue disease, and myositis associated with cancer. However, this measure has been criticised for several reasons including lack of specific criteria to help distinguish between muscle biopsy findings of PM, DM, and immune-mediated necrotising myopathy, as well as the lack of identification of cases of overlap myositis (OM. Because of this issue, other classification criteria for IIM have been proposed, which include utilising myositis-associated antibodies and myositis-specific antibodies, as well as overlap features such as Raynaud’s phenomenon, polyarthritis, oesophageal abnormalities, interstitial lung disease, small bowel abnormalities such as hypomotility and malabsorption, and renal crises, amongst others. Indeed, the identification of autoantibodies associated with certain clinical phenotypes of myositis, in particular connective tissue disease-myositis overlap, has further helped divide IIM into distinct clinical subsets, which include OM and overlap syndromes (OS. This paper reviews the concepts of OM and OS as they pertain to IIM, including definitions in the literature, clinical characteristics, and overlap autoantibodies.

    Full Text Available Abstract Background Compelled by the intuitive appeal of predicting each individual patient’s risk of an outcome, there is a growing interest in risk prediction models. While the statistical methods used to build prediction models are increasingly well understood, the literature offers little insight to researchers seeking to gauge a priori whether a prediction model is likely to perform well for their particular research question. The objective of this study was to inform the development of new risk prediction models by evaluating model performance under a wide range of predictor characteristics. Methods Data from all births to overweight or obese women in British Columbia, Canada from 2004 to 2012 (n = 75,225 were used to build a risk prediction model for preeclampsia. The data were then augmented with simulated predictors of the outcome with pre-set prevalence values and univariable odds ratios. We built 120 risk prediction models that included known demographic and clinical predictors, and one, three, or five of the simulated variables. Finally, we evaluated standard model performance criteria (discrimination, risk stratification capacity, calibration, and Nagelkerke’s r2 for each model. Results Findings from our models built with simulated predictors demonstrated the predictor characteristics required for a risk prediction model to adequately discriminate cases from non-cases and to adequately classify patients into clinically distinct risk groups. Several predictor characteristics can yield well performing risk prediction models; however, these characteristics are not typical of predictor-outcome relationships in many population-based or clinical data sets. Novel predictors must be both strongly associated with the outcome and prevalent in the population to be useful for clinical prediction modeling (e.g., one predictor with prevalence ≥20 % and odds ratio ≥8, or 3 predictors with prevalence ≥10 % and odds ratios ≥4.

    Franc Strle

    Full Text Available Clinical characteristics associated with isolation of Borrelia burgdorferi sensu lato from skin have not been fully evaluated. To gain insight into predictors for a positive EM skin culture, we compared basic demographic, epidemiologic, and clinical data in 608 culture-proven and 501 culture-negative adult patients with solitary EM. A positive Borrelia spp. skin culture was associated with older age, a time interval of >2 days between tick bite and onset of the skin lesion, EM ≥ 5 cm in diameter, and location of the lesion on the extremities, whereas several other characteristics used as clinical case definition criteria for the diagnosis of EM (such as tick bite at the site of later EM, information on expansion of the skin lesion, central clearing were not. A patient with a 15-cm EM lesion had almost 3-fold greater odds for a positive skin culture than patients with a 5-cm lesion. Patients with a free time interval between the tick bite and onset of EM had the same probability of a positive skin culture as those who did not recall a tick bite (OR=1.02; however, the two groups had >3-fold greater odds for EM positivity than patients who reported a tick bite with no interval between the bite and onset of the lesion. In conclusion, several yet not all clinical characteristics used in EM case definitions were associated with positive Borrelia spp. skin culture. The findings are limited to European patients with solitary EM caused predominantly by B. afzelii but may not be valid for other situations.

    Full Text Available Background and Design: Behçet’s disease (BD is a multisystem inflammatory disorder that is an important cause of morbidity worldwide. In this study, we aimed to investigate the clinical and demographic characteristics of Turkish patients diagnosed with BD. Materials and Methods: We retrospectively evaluated the hospital records of patients with BD who attended the Dermatoveneorology Department at the GATA Haydarpaşa Teaching and Research Hospital between 2001 and 2012. One hundred eighty-two male patients who met the diagnostic criteria of the International Study Group for BD were included in the study. The clinical and demographic characteristics, including symptoms and age at onset, systemic symptoms, duration of the disease and initial signs were recorded. Results: The ages of the 182 male patients included in the study varied from 20 to 53. The mean age at disease onset was 20.59±4.55 years. The leading clinical features were aphthous ulcers (100% followed by genital ulcers (86.8% and papulopustular lesions (80.3%. The pathergy test was positive in 57.3% of the patients. Ocular involvement was present in 527%, vascular involvement in 22.5%, and neurological manifestations was found in 7.1% of the patients. Joint involvement was reported in 18.1% of the subjects. Only 0.5% had genitourinary involvement. There was no relationship of BD with the age at onset and disease duration. Conclusion: We assume that the present study will contribute to the data on demographic and clinical characteristics of especially male BD patients in Turkey

    Chronic pain is common in HIV, but incompletely characterized, including its underlying etiologies, its effect on healthcare utilization, and the characteristics of affected patients in the HIV primary care setting. These data are needed to design and justify appropriate clinic-based pain management services. Using a clinical data warehouse, we analyzed one year of data from 638 patients receiving standard-of-care antiretroviral therapy in a large primary care HIV clinic, located in the Harlem neighborhood of New York City. We found that 40% of patients carried one or more chronic pain diagnoses. The most common diagnoses were degenerative musculoskeletal disorders (eg, degenerative spinal disease and osteoarthritis), followed by neuropathic pain and headache disorders. Many patients (16%) had multiple chronic pain diagnoses. Women, older patients, and patients with greater burdens of medical illness, and psychiatric and substance use comorbidities were disproportionately represented among those with chronic pain diagnoses. Controlling for overall health status, HIV patients with chronic pain had greater healthcare utilization including emergency department visits and radiology procedures. In summary, our study demonstrates the high prevalence of chronic pain disorders in the primary care HIV clinic. Colocated interventions for chronic pain in this setting should not only focus on musculoskeletal pain but also account for complex multifaceted pain syndromes, and address the unique biopsychosocial features of this population. Furthermore, because chronic pain is prevalent in HIV and associated with increased healthcare utilization, developing clinic-based pain management programs could be cost-effective.

    To explore the clinical characteristics, imaging manifestation, diagnosis and treatment for histoplasmosis and to improve therapeutic level, we retrospectively analyzed the clinical data of 8 patients with biopsy-confirmed histoplasmosis from 2004 to 2014 in the Second Xiangya Hospital of Central South University and reviewed relevant literatures. The main clinical symptoms of histoplasmosis included fever, cough, expectoration, chest pain, blood-stained sputum, lymphadenectasis, etc. The major lung imaging features were mass, node or pneumonia-like performance. No case was diagnosed as histoplasimosis firstly. Four patients whose imaging manifestations were focal pulmonary lesion received lobectomy of lung lesions or wedge resection. Clinical and imaging manifestations in 3 patients, who treated with amphotericin B or its liposomal, itraconazole or fluconazole, were improved. The clinical symptoms and imaging findings of histoplasmosis are nonspecific. It is easy for the physicians to misdiagnose histoplasmosis as bacterial infection, lung cancer, tuberculosis lymphoma, etc. Therefore, it is significant and necessary to carry out multiple biopsies combined with multiple etiological examinations for patients with difficult diagnosis.

    Full Text Available Background: thyroid disease is one of the most prevalent medical conditions and thyroid cancer is the most common endocrine neoplasm. Thyroid reoperations are more common than it might seem.Objective: to establish the clinical and epidemiological characteristics of patients operated on for colloid goiter undergoing reoperation for recurrent thyroid disease.Methods: a case-series study was conducted at the León Cuervo Rubio Clinical-Surgical Hospital in Pinar del Rio. The sample included all patients (n = 29 who underwent thyroid operation and were reoperated on for recurrent thyroid disease in 2010, 2011 and 2012. The information was obtained from medical records and the register of histopathological diagnoses.Results: most patients (27.6% were in the 40-49 age group and females (79.3% were most affected. Recurrence was observed 5 to 9 years after surgery. Mixed nodules (55.2% followed by cysts (17.2% were the most frequent ultrasound diagnoses. Recurrent thyroid disease was malignant in 9% of patients.Conclusions: patients reoperated on for thyroid disease were mostly females in the fourth and fifth decade of life. The disease recurred in a period of 10 years after the first surgery in a greater number of cases. Follicular-patterned lesions, colloid goiter and cancer were the most common histologic diagnosis.

    Background Tumor involving the septum pellucidum is uncommon. Surgery as the main therapeutic procedure for this lesion is a challenge to neurosurgeons. We analyzed the clinical characteristics and pathological features of septum pellucidum tumor in 41 patients and compared the curative effects of frontal transcortical, trans-sulcal and interhemispheric transcallosal approaches. Methods Clinical characteristics and the pathological features of septum pellucidum tumor were investigated retrospectively in 41 patients. The differences in postoperative residual rates, extents of tumors and resection of normal brain tissues after use of the three approaches in these patients were analyzed statistically. Results Septum pellucidum tumor is more likely to attack young or middle-aged persons. The tumor mainly presents itself as a central neurocytoma or cerebral low-grade glioma in pathology and manifests as intracranial hypertension clinically. No difference was found in the extent of tumor resection but significant difference in the extent of normal brain tissue resection and in postoperative disability rate among the three approaches. The transcortical approach brought about the most serious injury to brain tissue and the highest disability rate, Whereas the frontal transcallosal approach the lightest injury and the lowest disability rate. The injury to brain tissue and the disability rate brought about by the front trans-sulcus approach were between the above two approaches. Conclusions Operation is still regarded the major treatment for septum pellucidum tumor. Transcallosal and trans-sulcus approaches are fit with the concept of minimally invasive surgery, and transcallosal approach is the first choice for septum pellucidum tumor.

    AIM: To assess the clinical characteristics of Helicobacterpylori(H pylori) negative duodenal ulcer.METHODS: Patients with an endoscopic diagnosis of duodenal ulcer between 1996 and 2002 were included in the present study. Patients were considered to be negative for Hpylori, if both histological examination and rapid urease test of biopsy specimens were negative. A comparison was made between patients with H pyloripositive and negative duodenal ulcers.RESULTS: A total of 1 343 patients were studied. Their mean age was 54.7±0.5 years. There was a male preponderance (M:F = 2.5:1). Three hundred and ninetyeight patients (29.6%) did not have H pylori infection. The annual proportion of patients with H pylori negative duodenal ulcers increased progressively from 1996 to2002. On multivariate analysis, patients with H pylorinegative duodenal ulcer were more likely to be older, have concomitant medical problem, pre-existing malignancy, recent surgery, underlying sepsis, or taken non-steroidal anti-inflammatory drugs. In terms of clinical presentations, patients with H pylori negative duodenal ulcer were more likely to present with bleeding, multiple ulcers and larger ulcers.CONCLUSION: The proportion of patients with H pylori negative duodenal ulcers is on the rise because of a continued drop in incidence of H pylori positive duodenalulcers in recent years. Such patients have distinct clinical characteristics and it is important to ascertain the H pylori status before starting eradication therapy.

    2002-01-01

    The contribution of the high LET particles to dosimetric and microdosimetric characteristics of 150 and 205 MeV clinical proton beams was experimentally studied using track etched detectors. Secondary heavy charged particles produced from nuclear interactions and degraded protons at the Bragg peak region are particles with high LET. The method of the LET spectra measurement with track etched detectors allows one to determine the contribution of high LET particles to dosimetric characteristics of clinical proton beams: absorbed dose, equivalent dose and the value of the Relative Biological Effectiveness (RBE). Track detectors were irradiated in the various depth of clinical proton beams with the primary energies of 150 and 205 MeV. The LET spectra between 10 and 700 keV/m were measured by means of CR-39 track etched detectors and the automatic optical image analyzer LUCIA-II. The relative contribution of the high LET particles to absorbed dose increases from several per cent at the beam entrance to several ten...

    Full Text Available Objectives: There is significant evidence that psychotherapy is a pivotal treatment for persons diagnosed with Axis I clinical psychiatric conditions; however, a psychotherapy service has only recently been established in the Omani health care system. This study aimed to investigate the sociodemographic and clinical characteristics of attendees at a psychotherapy clinic at a tertiary care hospital. Methods: An analysis was carried out of 133 new referrals to the Psychotherapy Service at Sultan Qaboos University Hospital, a tertiary care hospital. Results: The majority of referrals were females (59%, aged 18–34 years, employed (38%, had ≤12 years of formal education (51%, and were single (54%. A total of 43% were treated for anxiety disorders (including obsessive compulsive disorder, while 22% were treated for depression. A total of 65% were prescribed psychotropic medications. The utilisation of the Psychotherapy Service and its user characteristics are discussed within the context of a culturally diverse Omani community which has unique personal belief systems such as in supernatural powers (Jinn, contemptuous envy (Hassad, evil eye (Ain and sorcery (Sihr which are often used to explain the aetiology of mental illness and influence personal decisions on utilising medical and psychological treatments. Conclusion: Despite the low number of referrals to the Psychotherapy Service, there is reason to believe that psychotherapy would be an essential tool to come to grips with the increasing number of mental disorders in Oman.

    AIM: To analyze the clinical characteristics of Chinese hereditary nonpolyposis colorectal cancer (HNPCC) families and to screen the germline mutations of human mismatch repair genes hMLH1 and hMSH2 in the probands.METHODS: Thirty-one independent Chinese HNPCC families were collected in Zhejiang Province. All of them met Chinese HNPCC criteria. Clinical data about patient gender, site of colorectal cancer, age of onset, history of multiple colorectal cancer, associated extracolonic cancer were recorded. PCR and denaturing high performance liquid chromatography (DHPLC) were employed to screen the mutations. Sequencing analysis was used to find out the exact mutation site and characteristics of the samples showing abnormal DHPLC profiles.RESULTS: One hundred and thirty-six malignant neoplasms were found in 107 patients including 14 multiple cancers. One hundred and six of the 136 neoplasms (77.9%) were diagnosed as colorectal cancer, with an average age of onset at 48.57 ± 29.00 years. Gastric cancer was the most common extracolonic cancer (10.3%) in these families. Twenty-three different sequence variations in hMLH1 and hMSH2 genes were detected in these 17 families. Fifteen sequence variations were located in the exons, including 5 SNPs, 3 silent mutations, 3 missense mutations, 2 nonsense mutations and 2 frameshift mutations. The latter seven mutations seemed to be pathogenic.CONCLUSION: Germline mutations of hMLH1 and hMSH2 genes are identified in about one-third HNPCC kindreds fulfilling Chinese HNPCC criteria. Chinese HNPCC families have some particular clinical characteristics, such as a left-sided predominance, less synchronous or metachronous colorectal cancer, and frequent occurrence of gastric cancer.

    Aims Data on differences in clinical characteristics and management of COPD in different countries and settings are limited. We aimed to characterize the profile of patients with COPD in a number of countries and their treatment in order to evaluate adherence to recommendations of international guidelines. Method This was an observational, international, cross-sectional study on patients with physician-diagnosed COPD. Demographic and clinical characteristics, risk factors, and treatment were collected by their physician via an internet web-based questionnaire developed for the study. Results A total of 77 investigators from 17 countries provided data on 833 patients. The countries with the highest number of patients included were: Argentina (128), Ecuador (134), Spain (162), and Hong Kong (153). Overall, 79.3% were men and 81% former smokers, with a mean FEV1 = 42.7%, ranging from 34.3% in Hong Kong to 58.8% in Ecuador. Patients reported a mean of 1.6 exacerbations the previous year, with this frequency being significantly and negatively correlated with FEV1(%) (r = −0.256; p < 0.0001). Treatment with short-acting bronchodilators and theophyllines was more frequent in Ecuador and Hong Kong compared with Spain and Argentina, and in patients belonging to lower socioeconomic levels (p < 0.0001 for all comparisons). Inadequacy of treatment with inhaled corticosteroids and theophyllines was high, with significant differences among countries. Conclusions Differences in the clinical characteristics and management of COPD were significant across countries. Adherence to international guidelines appears to be low. Efforts should be made to disseminate and adapt guidelines to the socioeconomic reality of different settings. PMID:19281096

    Even though the Beck Anxiety Inventory (BAI) is one of the most popular instruments to assess anxiety today, only limited data is available about its psychometric characteristics and normative values in clinical Spanish populations. A study was conducted to test the psychometric characteristics of a Spanish adaptation of the Beck Anxiety Inventory (BAI) in a sample of 918 outpatients being treated at a community mental health center in Spain. Results confirmed the adaptation's high internal consistency (∝ = .91), substantial test-retest reliability at 8-10 weeks (r = .84, p Anxiety (r = .86, p Phobic Anxiety (r = .63, p < .01) dimensions of the SCL-90-R, and with the Anxious Thoughts Inventory (r = .57, p < .01). Gender differences in BAI scores did occur, so normative values appear separately for each gender.

    Infection is one of the most devastating outcomes of cardiovascular implantable electronic device (CIED) implantation and is related to significant morbidity and mortality. In our country, there is no evaluation about CIED infection. Therefore, our aim was to investigate clinical characteristics and outcome of patients who had infection related to CIED implantation or replacement. The study included 144 consecutive patients with CIED infection treated at 11 major hospitals in Turkey from 2005 to 2014 retrospectively. We analyzed the medical files of all patients hospitalized with the diagnosis of CIED infection. Inclusion criteria were definite infection related to CIED implantation, replacement, or revision. Generator pocket infection, with or without bacteremia, was the most common clinical presentation, followed by CIED-related endocarditis. Coagulase-negative staphylococci and Staphylococcus aureus were the leading causative agents of CIED infection. Multivariate analysis showed that infective endocarditis and ejection fraction were the strongest predictors of in-hospital mortality.

    Background: Von Hippel–Lindau (VHL) syndrome is a dominantly inherited multisystem cancer syndrome caused by a heterozygous mutation in the VHL tumor suppressor gene. Previous studies suggested that similar populations of Caucasian and Japanese patients have similar genotype or phenotype characteristics. In this comprehensive study of East Asian patients, we investigated the genetic and clinical characteristics of patients with VHL syndrome. Methods: To create a registry of clinical characteristics and mutations reported in East Asian patients with VHL syndrome, we conducted a comprehensive review of English language and non‑English language articles identi‑fied through a literature search. Publications in Japanese or Chinese language were read by native speakers of the language, who then performed the data extraction. Results: Of 237 East Asian patients with VHL syndrome, 154 unique kindreds were identified for analysis. Analyzed by kindred, missense mutations were the most common (40.9%, 63/154), followed by large/complete deletions (32.5%, 50/154) and nonsense mutations (11.7%, 18/154). Compared with a previously reported study of both East Asian and non‑East Asian patients, we found several key differences. First, missense and frameshift mutations in the VHL gene occurred less commonly in our population of East Asian patients (40.9% vs. 52.0%; P = 0.012 and 8.4% vs.13.0%; P < 0.001, respectively). Second, large/complete deletions were more common in our population of East Asian patients (32.5% vs. 10.5%; P < 0.001). Third, phenotypically, we observed that, in our population of East Asian patients with VHL syndrome, the incidence of retinal capillary hemangioblastoma was lower, whereas the incidence of renal cell carcinoma was higher. Conclusions: Evidence suggests that the genotypic and phenotypic characteristics of East Asian patients with VHL syndrome differ from other populations. This should be considered when making screening recommendations for

    Full Text Available Background: The aim of our study was to investigate the clinical and histopathological characteristics of cutaneous leishmaniasis (CL in the city of Sanliurfa in Turkey, where Syrian refugees also reside. Materials and Methods: At the Harran University Hospital outpatient clinics between 2012 and 2013, 54 CL cases, including 24 Syrian patients, underwent punch biopsy of the skin and/or a touch imprint. Patients in whom leishmania parasites were detected were included in the study. The clinical and histopathological data of the patients were obtained by a review of the patients′ medical records. All the slides of each patient were re-evaluated histopathologically. Results: Fifty-four cases (mean age; 17 ± 12 years, consisting of 32 males (59.3% and 22 females (40.7%, were examined. The most common site of involvement was the face (63%. The most common presentation was noduloulcerative lesions (57.4%. Histopathologically, the majority of the cases exhibited hyperkeratosis, follicular plugging of the epidermis, chronic inflammatory infiltration, leishmania amastigotes and non-caseating granulomatous inflammation in the dermis. Conclusion: CL presents with a wide spectrum of expression, both clinically and histologically, and may mimic other inflammatory and neoplastic diseases. The diagnosis of CL relies on the identification of leishmania amastigotes in either a direct smear of the lesion or in a tissue section.

STUDY DESIGN: A self-administered questionnaire survey with a cross-sectional design was administered to consecutive attendees at four STD clinics in Zhejiang Province, China, between October and December in 2007. Demographic, psychosocial, and behavioural factors associated with oral sex over a lifetime were identified using univariate and multivariate analyses. RESULTS: Of the 872 attendees, 6.9% engaged in oral sex over their lifetimes. Of the oral-sex group, 96.6% also engaged in vaginal sex. The correlates for oral sex over a lifetime as determined by the multivariate analysis were high income (odds ratio [OR] = 2.53, 95% confidence interval [CI] 1.39-4.59, high human immunodeficiency virus (HIV-related knowledge (OR = 2.71, 95% CI 1.26-5.81, early sex initiation (OR = 2.42, 95% CI 1.37-4.27, multiple sexual partners (OR = 3.09, 95% CI 1.58-6.06, and sexually active in the previous 6 months (OR = 7.73, 95% CI 1.04-57.39. CONCLUSIONS: Though the prevalence of oral sex is low, the heterosexual STD clinic attendees practicing oral sex was found to have higher risks associated with STD/HIV transmission than those not. Behavioural and medical interventions conducted by clinicians in Chinese STD clinics should take into account the characteristics and related risks of those who practice oral sex.

    Full Text Available OBJECTIVE: Pituitary stalk interruption syndrome (PSIS is characterized by the absence of pituitary stalk, pituitary hypoplasia, and ectopic posterior pituitary. Due to the rarity of PSIS, clinical data are limited, especially in Chinese people. Herein, we analyzed the clinical characteristics of patients diagnosed with PSIS from our center over 10 years. PATIENTS AND METHODS: We retrospectively analyzed the clinical manifestations and laboratory and MRI findings in 55 patients with PSIS. RESULTS: Of the 55 patients with PSIS, 48 (87.3% were male. The average age was 19.7±6.7 years and there was no familial case. A history of breech delivery was documented in 40 of 45 patients (88.9% and 19 of 55 patients (34.5% had a history of dystocia. Short stature was found in 47 of 55 patients (85.5% and bone age delayed 7.26±5.37 years. Secondary sex characteristics were poor or undeveloped in most patients. The prevalence of deficiencies in growth hormone, gonadotropins, corticotropin, and thyrotropin were 100%, 95.8%, 81.8%, 76.3%, respectively. Hyperprolactinemia was found in 36.4% of patients. Three or more pituitary hormone deficiencies were found in 92.7% of the patients. All patients had normal posterior pituitary function and absent pituitary stalk on imaging. The average height of anterior pituitary was 28 mm, documented anterior pituitary hypoplasia. Midline abnormalities were presented in 9.1% of patients. CONCLUSIONS: The clinical features of our Chinese PSIS patients seem to be different from other reported patients in regarding to the higher degree of hypopituitarism and lower prevalence of midline defects. In addition, our patients were older at the time of case detection and the bone age was markedly delayed. We also had no cases of familial PSIS.

    To summarize the clinical characteristics of intracranial arachnoid cysts (IACs) in pediatric cases. A retrospective analysis was carried out on clinical characteristics of IACs in 488 pediatric cases who were treated at our hospital from January 2003 to September 2013. There were 342 males and 146 females (male-to-female ratio, 2.34:1), aged 5.61±3.25 years on average. 221 cases (45.29%) were diagnosed accidentally, 267 cases had clinical complaints (54.71%), among which relationships between clinical complaints and IACs were identified in 123 (46.07%). Simple IACs occurred in 364 cases (4.59%), and concurrent congenital abnormalities occurred in 124 cases (4.59%). In terms of location, 355 had IACs in middle cranial fossa (72.75%), 82 cases in posterior cranial fossa (16.80%), 20 cases in anterior cranial fossa (4.10%), 12 cases in dorsolateral surface (2.46%), 7 cases in suprasellar cistern (1.43%), 5 cases in cerebral ventricle (1.02%), 5 cases in quadrigeminal cistern (1.02%), and 2 cases in interhemispheric region (0.41%). There were 449 cases with single IAC (92.01%) and 39 cases with multiple IACs (7.99%). On MRI, the cysts produced tension in 127 cases (26.02%), but not in the remaining 361 cases (73.98%). Surgery was performed on 76 of 488 cases (15.57%), while conservative observation was accepted in 412 cases (84.43%). For the former, the symptoms and the cyst volume were improved to varying extent; for the latter, the follow-up lasting for 3-72 months (average 32.43±8.92 months) showed that the cyst volume remained stable in 407 cases (98.78%), enlarged with aggravated symptoms in 3 cases (0.73%), and shrank in 2 cases (0.49%). Clinical complaints of IACs varied in pediatric cases, and the relationships between clinical complaints and IACs were established only partially. Some pediatric cases were combined with other congenital abnormalities. The cyst volume largely remained stable during the disease course, and surgery was required for only a few

    Full Text Available Abstract Background Gaucher disease (GD is due to deficiency of the glucocerebrosidase enzyme. It is panethnic, but its presentation reveals ethnicity-specific characteristics. Methods We evaluated the distribution, and clinical and genetic characteristics of GD patients in the Iberian Peninsula (IP. We analysed geographical distribution, demographic, genetic and clinical data, age at diagnosis, type, and years of therapy in 436 GD patients from the IP. Results The prevalence of GD was 1/149,000 inhabitants; 88.3% were type 1, 6.7% type 2, and 5.0% type 3. The mean age at diagnosis in type 1 was 28.7 years. A total of 72.7% were classified as having mild forms, 25.5% moderate, and 1.7% severe. Anemia and thrombocytopenia were present in 56% and 55%, respectively. Bone disease and hepatomegaly were reported in 62% and 68%, respectively, and were more likely in asplenic than in non-splenectomized patients. Sixty-nine mutant alleles were identified, and five mutations accounted for 75% of the GBA alleles. Several patients described in our series had interesting phenotypes. A total of 58.7% of patients had received enzyme replacement therapy and 12.6% were treated with miglustat. Conclusions A broad spectrum of GBA mutations is present in the IP, with 98.2% of type 1 GD being mild and 23.0% never treated. These data highlight genetic and phenotypic heterogeneities among geographic populations.

    Middle cerebral artery (MCA) aneurysms usually arise at the primary MCA bifurcation or trifurcation. Distal MCA aneurysms are rarely considered as sources of aneurysmal subarachnoid hemorrhage (SAH). It has been reported that ruptured distal MCA aneurysms are associated with head trauma, neoplastic emboli, arterial dissection, or bacterial infection. We experienced five cases of ruptured distal MCA aneurysms and evaluated their clinical characteristics. Retrospective analysis of aneurysmal SAH at Kobayashi Neurosurgical Neurological Hospital was performed from January, 2004 to December, 2014. Clinical characteristics of ruptured distal MCA aneurysms were analyzed using our database. Among 191 aneurysmal SAH patients, there were five ruptured distal MCA aneurysms. All patients did not have any specific medical problems such as infectious disease, head trauma, or cardiac disorders. The incidence of ruptured distal MCA aneurysm was higher than expected and was equivalent to 9.4% of the total ruptured MCA aneurysms. Strong male predominance (80%) and M2-3 junction aneurysm preponderance (80%) were observed. In addition, there were only two patients (40%) with intracerebral hematoma in our study. We reported five cases of ruptured distal MCA aneurysms. Although ruptured distal MCA aneurysms are thought to be rare as sources of aneurysmal SAH, the incidence of ruptured distal MCA aneurysm was 9.4% of all ruptured MCA aneurysms in our study. Ruptured distal MCA aneurysms should be considered as sources of aneurysmal SAH without intracerebral hematoma.

    Full Text Available Background. To describe the clinical characteristics of the patients who suffered from relapse after conventional irradiation for nasopharyngeal carcinoma (NPC. Methods. Three hundred and fifty-one consecutive patients with first-time recurrent NPC between January 1999 and July 2005 were included. The patients’ clinical data were reviewed, including recurrent interval time, symptoms, signs, imaging characteristics, pathologic features, and restaging. Results. The median interval of relapse was 26.0 months. The most common symptoms in symptomatic patients were nasal bloody discharge (37.9% and headache (31.1%. Local recurrence alone accounted for 73.5%. Most patients were restaged as stage III (23.1% and stage IV (51.1%. Subgroup analysis suggested a significantly higher proportion of the long-latent relapses originated from early primary. A series of postreirradiation complications were more frequent in patients with longer latency at reception. Conclusions. Most recurrent nasopharyngeal carcinoma is advanced disease. Patients with different recurrent interval time show different nature behavior.

    Anne Guimier

    Full Text Available BACKGROUND: Somatically acquired genomic alterations with MYCN amplification (MNA are key features of neuroblastoma (NB, the most common extra-cranial malignant tumour of childhood. Little is known about the frequency, clinical characteristics and outcome of NBs harbouring genomic amplification(s distinct from MYCN. METHODS: Genomic profiles of 1100 NBs from French centres studied by array-CGH were re-examined specifically to identify regional amplifications. Patients were included if amplifications distinct from the MYCN locus were seen. A subset of NBs treated at Institut Curie and harbouring MNA as determined by array-CGH without other amplification was also studied. Clinical and histology data were retrospectively collected. RESULTS: In total, 56 patients were included and categorised into 3 groups. Group 1 (n = 8 presented regional amplification(s without MNA. Locus 12q13-14 was a recurrent amplified region (4/8 cases. This group was heterogeneous in terms of INSS stages, primary localisations and histology, with atypical clinical features. Group 2 (n = 26 had MNA as well as other regional amplifications. These patients shared clinical features of those of a group of NBs MYCN amplified (Group 3, n = 22. Overall survival for group 1 was better than that of groups 2 and 3 (5 year OS: 87.5%±11% vs 34.9%±7%, log-rank p<0.05. CONCLUSION: NBs harbouring regional amplification(s without MNA are rare and seem to show atypical features in clinical presentation and genomic profile. Further high resolution genetic explorations are justified in this heterogeneous group, especially when considering these alterations as predictive markers for targeted therapy.

    Full Text Available Abstract Objective This study reports the clinical characteristics and outcome of HIV-associated Penicilliummarneffei infection in northern Vietnam. Methods We conducted a retrospective chart review of all patients with laboratory confirmed Penicilliummarneffei infection admitted to the National Hospital for Tropical Diseases in Hanoi, Vietnam, between July 2006 and September 2009. Results 127 patients with P. marneffei infection were identified. All were HIV-infected; median CD4+ T-cell count was 24 cells/μl (IQR:12-48; 76% were men. Common clinical features were fever (92.9%, skin lesions (82.6%, hepatomegaly (61.4%, lymphadenopathy (40.2%, weight loss (59.1% and cough (49.6%. Concurrent opportunistic infections were present in 22.0%; half of those had tuberculosis. Initial treatment regimens were: itraconazole or ketoconazole capsule (77.2%, amphotericin B (20.5%, and fluconazole (1.6%. In-hospital mortality was 12.6% and showed no significant difference in patients treated with itraconazole (or ketoconazole and amphotericin B (p = 0.43. Dyspnea, ascites, and increased LDH level were independent predictors of mortality. No seasonality was observed. Conclusion The clinical features, treatments and outcomes of HIV-associated P. marneffei infection in northern Vietnam are similar to those reported in other endemic regions. Dyspnea was an important predictor of mortality. More patients were treated with itraconazole than amphotericin B and no significant difference in treatment outcome was observed. It would be of clinical value to compare the efficacy of oral itraconazole and amphotericin B in a clinical trial.

    Critical issue regarding to variation of findings based on different phenotypes led investigators to define whether they are distinct features or overlapping ones. Therefore, we aimed to investigate the association between diverse phenotypes of PCOS (Poly Cystic Ovary Syndrome) with clinical manifestations, anthropometric indices, and metabolic characteristics. This was a descriptive cross-sectional study conducted in 15-39 years old women with PCOS referred to infertility clinics in the north part of Iran, Rasht during 2010-2011. Data were gathered through an interview by a form consisted of demographic characteristics, laboratory findings, ovarian volume and anthropometric indices. A total of 214 patients consisted of 161 PCOS (cases) and 53 normal women (controls) participated in this study. The most prevalent phenotype in PCOS population was IM/PCO/HA (54%), followed by IM/HA (28%) and IM/PCO (13%). PCO/HA was present only in 6 PCOS patients (5%). PCOS patients were significantly younger than controls (P=0.07). Results showed that increased ovarian volume were higher in PCOS group in comparison with controls and IM/PCO/HA, and IM/PCO had respectively the largest ovarian volumes. Also, a significant relation was observed based on Cholesterol, 17OHP, LH, TG, 2hpp, and LH/FSH between patients with PCOS and control groups. There were significant differences in demographic, anthropometric, hormonal and ultrasound findings between PCOS and controls. Therefore, it seems that classification of the characteristics of each phenotype could offer an appropriate guide for screening risks of PCOS and may facilitate performing most favorable treatment for these complications.

    The objective is to clarify the early clinical characteristics in childhood moyamoya disease (MD). Epidemiologic characteristics, symptoms and diagnostic rates were assessed in 64 children (0-18 years) with definite MD according to developmental stage: infancy (5; 0-1 years); toddlerhood/preschool age (22; 2-5 years); school age (29; 6-10 years); and adolescence (8; 11-18 years). The median ages at onset was 6.25 years and the female to male ratio was 1.9 (~2.5 in toddlerhood/preschool age and in adolescence, P=0.71). Previous headache was observed in 23% (14/64): frequently in school age (38%, P=0.02) and within 6 months before main symptoms (6/11). As an initial symptom, weakness was observed in 78% (50/64) mainly as transient ischemic attack (TIA, 61%) in limbs (90%) and unilaterally (82%). TIA was less frequent in infancy (40%, P=0.04). Seizure was observed in 27% (17/64): frequently in infancy (100%, Pchildren ~5 years (P<0.01). Severe headache associated with MD was observed in 14% (9/64). Provoking events were positive in 42% (27/64): in school age, frequently during eating (28%); and in toddlerhood/preschool age, during crying (27%). The diagnostic rates at 3 and 12 months from symptom-onset were 39% (80% during infancy vs. 28% in school age, P=0.14) and 67%, respectively. Symptomatic progression at diagnosis was observed in 38% (24/64). Initial clinical characteristics in childhood definite MD differed according to developmental stage and from at diagnosis.

    Full Text Available Objective To investigate the clinical characteristics of patients suffering from acute superior mesenteric venous thrombosis (ASMVT. Methods Clinical data of 96 ASMVT patients admitted to the PLA General Hospital from January 2000 to December 2013 were retrospectively analyzed. Clinical characteristics and death-associated risk factors were studied, and the influence of treatment strategy and thrombosis location on patients' outcome were analyzed. Results The patients were divided into survival group (n=83 and death group (n=13 according to the outcome. The mean age was 46.9 years old, and the ratio of male/female was 3:1. Thirty-nine patients presented isolated superior mesenteric venous thrombosis (SMVT and fiftyseven patients presented combined SMVT. In the death group, higher incidence of severe acute pancreatitis and isolated SMVT were found than the survival group (P<0.01, P=0.004. The patients were again divided into laparotomy group, interventional thrombolysis group, and conservative treatment group according to treatment modality. The interval between symptom onset and treatment was shorter, the incidence of isolated SMVT and mortality rate were higher in the laparotomy group compared with those in interventional thrombolysis group and conservative treatment group. There was no death in the conservative treatment group. In comparison with the combined SMVT group, more patients in the isolated SMVT group presented peritoneal signs and less with history of splenectomy (P<0.001, P=0.002. The proportion of patients with laparotomy and bowel necrosis in the isolated SMVT group was higher than those in the combined SMVT group (P=0.023, P=0.012. Conclusions Patients with isolated SMVT are more likely to have peritoneal signs and bowel necrosis, surgical treatment is mandatory. Patients with combined SMVT often have a history of splenectomy. ASMVT patients with severe pancreatitis may present higher mortality rate. DOI: 10.11855/j

    The study was to research the clinical characteristics of Shenmai injection treating tumor based on hospital information system, including the characteristics of the age, the sex, the dosage, the course of the treatment and the combination drugs. The data of tumor patients injected with Shenmai injection was analyzed. The information was collected from the hospital information system (HIS) in twenty hospitals of grade III-A. The method of frequencies and association rules was used in this reaearch. The patients over 45 years old were up to 3 338, about 79.36% of the whole. The ratio of male and female was 1.73: 1. The hospitalization day between 15 and 28 was most. The complications of the hypertension and coronary heart disease happened most. The support was 5.939% and 5.099% respectively. Fifty-five patients had the traditional Chinese medicine (TCM) syndrome of Qi-Yin deficiency, about 14.78% of the whole. There were 8 491 patients treated with the single dose of 81 to 100 mL, about 48.70% of the whole. The main combination drugs were dexamethasone, tropisetron and maxolon. The confidence was 44.63%, 31.22% and 20.53% respectively. The information from HIS showed that tumor patients used Shenmai injection were most quinquagenarian with smooth condition. The dose of the Shenmai injection sometimes was higher than that of the drug use instructions in clinical. Shenmai injection was most often combined with glucocorticoid, antemetic and nutritional support medicine when treating tumor in clinical.

RESULTS:There were 35 published reports and 258 cases about myotonia congenita.Six reports(62 cases)were excluded due to lack of clinical data,imprecise diagnosis,or duplication.Finally,29 published reports and 196 cases(140 males and 56 females)were included in this analysis.About 78.6% of patients were diagnosed with myotonia congenita before the age of 20,and among these, 86.1% were classified as dominant inheritance.Lower and upper extremities were frequently affected with severe symptoms.Eyelids,mouth and lingual muscles,and trunk muscles and cervical muscles were less frequently involved.However,muscles for swallowing,sphincter muscles,and smoothmuscles were not involved.There were no reports of cataracts,cardiac conduction block,or dyscrinism. Myotonia congenita symptoms were induced or aggravated by cold temperatures in 71.9% of the patients and warming-up effect occurred in 95.6% of the patients.Muscle hypertrophy was observed in 69.6% and percussion of muscles in 76.5% of the patients.Myotonia potential or myotonia-likepotential was detected in all patients using electromyography.Muscle fiber swelling or hypertrophy was frequently detected through muscular biopsy.CONCLUSION:Myotonia congenita frequently occurs in males before the age of 20,in particular as the autosomal dominant form of myotonia congenita.Skeletal muscles throughout the body,especially the lower and upper extremities,are involved.However,muscles for swallowing,sphincter muscles, and smooth muscles are not involved.Warming-up effect is the main characteristic of myotonia congenita.

    Full Text Available Background & objectives: Discrepancies exist in the reported prevalence of portal vein thrombosis (PVT, and its clinical characteristics and sites of occurrence need to be elucidated. The risk factors for PVT are also poorly understood. This single centre study was undertaken to determine the clinical characteristics, sites of occurrence, and risk factors associated with PVT in patients with liver cirrhosis. Methods: Hospitalized cirrhotic patients (N = 162 were segregated into the PVT and non-PVT groups. Indices possibly associated with PVT were measured and PVT was detected by both Doppler ultrasonography and computed tomography portal angiography. The portal vein diameter and flow velocity and splenic thickness were measured by ultrasonography. Results: PVT was found in 40 patients (24.7%; in 34 PVT patients (85%, the liver cirrhosis resulted from hepatitis B virus infections. Most (90% patients were Child-Pugh classes B and C, with similar distribution between the groups. PVT was seen in 20 patients in the portal and superior mesenteric veins; ascites, abdominal pain, gastrointestinal bleeding, and jaundice were common findings in PVT patients. Haemoglobin levels and blood platelet counts (BPCs were significantly lower and splenic thickness was greater in PVT than in non-PVT patients (P<0.01. There was a significant positive correlation between BPCs and platelet aggregation rates (R = 0.533, P<0.01. Interpretation & conclusions: The occurrence of PVT was 24.7 per cent, primarily in post-hepatitis B liver cirrhosis patients. PVT occurred mainly in the portal vein trunk and superior mesenteric vein. Different PVT sites may account for the differing clinical presentations. The lower levels of haemoglobin and BPCs as well as splenic thickening were associated with PVT. Splenic thickening may be a risk factor for PVT.

    In order to explore the diagnosis and therapy of Diamond Blackfan anemia (DBA), the clinical data of 45 cases of DBA admitted in our hospital from February 1994 to July 2011 were analyzed retrospectively. The clinical characteristics, results of laboratory examination, treatment reaction and outcome of disease were investigated. The results indicated that out of 45 children diagnosed as DBA, 14 cases (31.1%) had short stature and physical malformation. All patients had anemia with reticulocytopenia. Thirty-four patients (75.6%) had mean corpuscular volume. Eleven patients (24.4%) had macrocytic anemia. Bone marrow examination showed a marked erythroid hypoplasia in all patients. Out of 29 cases tested for fetal hemoglobin (HbF), 13 cases (44.8%) had high level of HbF. Erythroid colony-forming unit of bone marrow was tested in 25 patients, among them 12 patients (48%) showed normal plasia, 13 (52%) showed hypoplasia. The erythropoietin (EPO) levels of 17 patients were elevated. Karyotypes were examined in 28 patients, and showed all normal. The treatment was based on corticosteroids and Cyclosporine A. Thirty patients had good response to corticosteroid therapy, and 10 of them obtained a sustained corticosteroid-induced remission. Twenty cases discontinued corticosteroid therapy after remission, as a result, 15 cases (75%) relapsed, moreover all the relapsed cases still had good response to corticosteroid. Two relapsed patients suffered from aplastic anemia, one of them died of therapy failure. Six patients were unresponsive to corticosteroid, 1 of which achieved remission with cyclosporine A and the others continued to receive regular transfusions. 3 patients received iron chelation therapy. It is concluded that the clinical characteristics, complete blood count, bone marrow smear, HbF level and EPO level are useful to make a diagnosis of DBA. Most patients have a good response to corticosteroid therapy, but relapse rate is high when drug was discontinued. Patients

    Full Text Available BACKGROUND: Human cystic echinococcosis (CE is caused by flatworm larvae of Echinococcus granulosus and is endemic in many parts of the world. In humans, CE cysts primarily affect the liver and pulmonary system, but can also affect the renal system. However, the clinical manifestations of renal CE can be subtle, so healthcare professionals often overlook renal CE in differential diagnosis. In this study, we examined the clinical and demographic characteristics of patients with urinary tract CE and analyzed the diagnosis and treatment procedures for this disease. METHODS: The records of 19 consecutive renal CE patients who were admitted to the First Affiliated Hospital of Xinjiang Medical University from January 1983 to April 2011 were retrospectively reviewed. In all cases, CE of the urinary tract was confirmed by pathological examination and visual inspection during surgery. RESULTS: Fifteen patients were males and 4 were females. The most common symptoms were non-specific lower back pain and percussion tenderness on the kidney region. All patients were followed up for 9-180 months after surgery. None of the patients experienced a recurrence of renal CE, but 4 patients experienced non-renal recurrence of hydatid disease. CONCLUSIONS: Hydatid cysts from E. granulosus are structurally similar in the liver and urinary tract. Thus, the treatment regimen for liver CE developed by the World Health Organization/Informal Working Group on Echinococcosis (WHO/IWGE could also be used for urinary tract CE. In our patients, the use of ultrasound, computed tomography, serology, and clinical characteristics provided a diagnostic accuracy of 66.7% to 92.3%.

    Full Text Available Introduction. Secondary lactose intolerance (SLI belongs to the rarer manifestations of gluten-sensitive enteropathy (GSE. It occurs in more severe forms of the disease and its presence contributes significantly to the degree of its expression. Objective. The goal of the study was to determine the frequency of SLI in infants with clinically classic form of GSE, as well as its relationship with the duration, severity and age at the diagnosis of the basic disease and the degree of small bowel mucosa damage. Methods. The study was based on a sample of 42 infants, 30 female and 12 male, aged 7-12 months (x=9.98±1.69, with a clinically classic form of GSE. The diagnosis of GSE was established based on the characteristic pathohistological appearance of small bowel mucosa and clinical improvement of patients on gluten-free diet, while SLI on pathological lactose or milk tolerance test. The assessment of basic disease severity was based on body mass divergence in relation to the standard value, as well as on Hb and serum iron levels, while the degree of small bowel mucosa damage was determined according to the modified Marsh criteria. Results. SLI was verified in 8/42 or 19.05% of patients. In addition to the symptoms and clinical signs of GSE, all the patients with SLI also featured the problems characteristic of lactose tolerance disorders, i.e. watery diarrhoea, borborygmus and meteorism occurring after milk meals. In addition, all had perianal erythema (6 with erosive changes, as well as destructive enteropathy (5 subtotal and 3 total. The difference in the duration of the basic disease, age at diagnosis, as well as in the degree of body mass deviation from the standard value between the lactose-tolerant and lactose-intolerant infants was not found. In addition, no difference in Hb and serum iron levels or in the degree of small bowel mucosa damage was found between the two groups. Conclusion. Our findings indicate that SLI presents a relatively

    Full Text Available Abstract Background Non-typhoidal Salmonella (NTS is increasingly recognized as an important pathogen associated with bacteraemia especially in immunosuppressed patients. However, there is limited data specifically describing the clinical characteristics and outcome amongst the immunosuppressed patients. Methods A total of 56,707 blood culture samples and 5,450 stool samples were received by the microbiology laboratory at a tertiary referral hospital in Malaysia, during a 4-year study period. Out of these samples, 55 non-duplicate NTS isolates were identified from blood and 121 from stool. A retrospective analysis of the 55 patients with NTS bacteraemia was then conducted to determine the predominant NTS serovars causing bacteraemia and its' blood invasive potential, epidemiological data, clinical characteristics and antimicrobial susceptibility. Patients were then grouped as immunosuppressed and non-immunosuppressed to determine the association of severe immunosuppression on clinical features. Data was analyzed using the Statistical Package for Social Sciences (SPSS version 15.0 using the non-parametric Mann-Whitney test, Fisher's exact test or Chi-squared test. The odds ratio (OR and its 95% confidence intervals (CI were calculated. The P-value Results Out of 55 NTS bacteraemia cases identified, 81.8% (45/55 were community-acquired. Salmonella enterica serovar Enteritidis had the highest blood invasiveness. An extra-intestinal focus of infection was noted in 30.9% (17/55 of the patients, most commonly involving the lungs and soft tissue. 90.9% (50/55 of the patients had an underlying disease and 65.5% (36/55 of the patients had severe clinical immunosuppressive condition with malignancy and HIV being the most common. Immunosuppressed patients had higher mortality (P = 0.04, presented more commonly with primary bacteraemia (P = 0.023, leukopenia (P = 0.001 and opportunistic infections (P = 0.01. In contrast, atherosclerotic conditions (P = 0

    There has been little research examining clinical correlates of childhood-onset pathologic skin picking in a sample of individuals with a primary diagnosis of pathologic skin picking. Using a sample of 40 consecutive subjects with current pathologic skin picking, we compared subjects with childhood-onset (before 10 years of age) pathologic skin picking to those with later onset on a variety of clinical measures. Symptom severity was examined by assessing time spent picking per day, intensity and frequency of thoughts and urges to pick, and social and occupational functioning. Of the 40 subjects, 19 (47.5%) reported onset of skin picking before 10 years of age. Subjects with childhood-onset had significantly longer durations of illness before receiving treatment and were more likely to pick unconsciously. Symptom severity, comorbidity, and social functioning did not differ between groups. These preliminary results suggest that although onset before 10 years of age is fairly common among people with pathologic skin picking, individuals developing this behavior earlier in life have similar clinical characteristics as those with later onset but may be less likely to seek treatment.

    The Sporothrix complex members cause sporotrichosis, a subcutaneous mycosis with a wide spectrum of clinical manifestations. Several specific phenotypic characteristics are associated with virulence in many fungi, but studies in this field involving the Sporothrix complex species are scarce. Melanization, thermotolerance, and production of proteases, catalase, and urease were investigated in 61 S. brasiliensis, one S. globosa, and 10 S. schenckii strains. The S. brasiliensis strains showed a higher expression of melanin and urease compared with S. schenckii. These two species, however, presented similar thermotolerances. Our S. globosa strain had low expression of all studied virulence factors. The relationship between these phenotypes and clinical aspects of sporotrichosis was also evaluated. Strains isolated from patients with spontaneous regression of infection were heavily melanized and produced high urease levels. Melanin was also related to dissemination of internal organs and protease production was associated with HIV-coinfection. A murine sporotrichosis model showed that a S. brasiliensis strain with high expression of virulence factors was able to disseminate and yield a high fungal burden in comparison with a control S. schenckii strain. Our results show that virulence-related phenotypes are variably expressed within the Sporothrix complex species and might be involved in clinical aspects of sporotrichosis. PMID:25961005

    Full Text Available Objective: To evaluate the clinical and immunological features of the hemorrhagic fever with renal syndrome in women of different age groups. Materials and methods: Clinical and laboratory characteristics of hemorrhagic fever with renal syndrome in 148 women aged 17 to 65 years old have been investigated. Patients have been divided into two groups: group I included 101 patients with normal menstrual rhythm, group II included 47 female patients with menopause. In 57 women (36 from group I, 21 — from group II the content of CD3+, CD4+, CD8+, CD16+, CD19+ — sub-populations of peripheral blood lymphocytes has been determined. Results: In compared groups significant differences in structure and frequency of complications of the disease have been revealed. Unidirectional tendency to increase significantly reduced absolute rates of investigated lymphocyte subpopulations in dynamics of the disease has been identified. It also has been stated that by the time of early convalescence in case of severe form of HFRS the indices did not reach the standard level. In an older group of women deeper damage and long-term recovery of immune system have been marked. Conclusion: According to the results of clinical and immunological studies the research work has revealed that in young women the response of the immune system to HFRS has developed faster and stronger than that in patients during the menopause period.

    Purpose Many health organizations and practitioners in the United States promote preconception health (PCH) to consumers. However, summaries and evaluations of PCH promotional activities are limited. Design We conducted a content analysis of PCH health education materials collected from local-, state-, national-, and federal-level partners by using an existing database of partners, outreach to maternal and child health organizations, and a snowball sampling technique. Setting Not applicable. Participants Not applicable. Method Thirty-two materials were included for analysis, based on inclusion/exclusion criteria. A codebook guided coding of materials’ characteristics (type, authorship, language, cost), use of marketing and behavioral strategies to reach the target population (target audience, message framing, call to action), and inclusion of PCH subject matter (clinical-behavioral components). Results The self-assessment of PCH behaviors was the most common material (28%) to appear in the sample. Most materials broadly targeted women, and there was a near-equal distribution in targeting by pregnancy planning status segments (planners and nonplanners). “Practicing PCH benefits the baby’s health” was the most common message frame used. Materials contained a wide range of clinical-behavioral components. Conclusion Strategic targeting of subgroups of consumers is an important but overlooked strategy. More research is needed around PCH components, in terms of packaging and increasing motivation, which could guide use and placement of clinical-behavioral components within promotional materials.

    Little is known regarding the clinical features and course of in-situ pulmonary artery thrombosis (PAT). The aim of the present study was to investigate the clinical characteristics of PAT. Patients with PAT were retrospectively identified from a tertiary referral center in South Korea. A control group consisted of patients with pulmonary embolism in whom the right or left pulmonary artery was the largest pulmonary embolism-involved site. We compared various clinical parameters between the two groups. Of the 23 PAT patients, the most common underlying condition was tuberculosis-destroyed lung [11 (47.8%)], followed by pulmonary artery stump after lobectomy or pneumonectomy [7 (30.4%)]. In all patients except one, PAT was located in the right or left pulmonary artery. Computed tomography scans demonstrated that clots were completely or partially resolved less frequently in the PAT group than in the control group [4 (25%) versus 62 (90%); P PAT group, three of the seven patients (43%) who had undergone anticoagulation therapy exhibited improvement, and one of the nine patients (11%) who had not received anticoagulation therapy experienced improvement; however, the difference was not significant. Tuberculosis-destroyed lung was the most common underlying condition in Korean PAT patients, followed by pulmonary artery stump after lung resection. The clots in patients with PAT were mostly located in the right or left pulmonary artery, and clot resolution was less frequent in the PAT group compared to the pulmonary embolism group.

    The aim of this study is to analyze the clinical characteristics and treatment of sudden sensorineural hearing loss (SSNHL) patients with vestibular schwannoma (VS). The clinical features of the VS patients were explored by retrospectively analyzing the clinical data from 542 cases of SSNHL patients between January 2008 and March 2013. There were 10 cases (10 ears) diagnosed with VS in 542 cases of SSNHL patients (10 ears, 1.85 %), 3 males, 7 females, with a range of 28-57 years. Among all the cases, eight patients with abnormal ABR, ten with ear ipsilateral stapedius reflexes which were completely not elicited and seven patients with healthy ear contralateral stapedius reflexes which were completely not elicited. Neuromas were classified by Koos grades according to size (8 of grade I, 1 of grade II, 1 of grade IV). Eight small VS  patients were taken waiting and MRI therapy strategies. Meanwhile, we used glucocorticoid treatment and timely and short-term medication to improve the microcirculation of the inner ear for these patients. And four cases' hearing was improved. Some vestibular schwannomas have SSNHL as initial symptoms, especially the small ones in internal auditory canal. To prevent misdiagnosis or leak-diagnosis, MRI should be performed as a routine test for SSNHL, and ABR is sometimes necessary for SSNHL patients. It is also necessary to give appropriate treatment to protect hearing of the small vestibular schwannoma patients whose first symptoms are diagnosed as SSNHL in acute phase.

    Background Primary intraspinal hemangiopericytoma is a rare malignant mesenchymal tumor with high rates of recurrence and metastasis. Surgery is the main therapeutic procedure for this lesion. This clinical research was undertaken to analyze the pathological characteristics, clinical course, and the choice of treatment for this lesion. Methods Twenty-three patients with primary intraspinal hemangiopericytomas were treated from 1987 to 2004. The clinical and imaging features, pathological findings, therapeutic procedures, and prognosis were analyzed retrospectively. Results Primary intraspinal hemangiopericytoma is more likely to attack middle-aged persons. The tumor mainly manifests as muscle weakness and sensor abnormalities. Microscopic examination showed slit-like vascular spaces and oral- or spindle-shaped cells with slightly acidic cytoplasm and oral nuclei. Tumors were subtotally resected in 11 patients, subtotally resected with postoperative radiotherapy in 4, totally resected in 5, and totally resected with postoperative radiotherapy in 3. Two patients were given spinal stabilization after total resection. Recurrence and metastatic rates were 50% and 0 in intradural patients. They were 73% and 27% in extradural patients, respectively. Conclusions The tumor should be resected en bloc with the neighboring dural mater to reduce recurrence and metastasis. Patients with subtotal resection need adjuvant radiotherapy. Patients with evident spinal involvement may benefit from spinal stabilization. The prognosis of the lesion arising from the dural mater is better.

    In this prospective, observational study of 618 consecutive adult patients with skin and soft tissue infections (SSTI) caused by methicillin-resistant Staphylococcus aureus (MRSA), the clinical characteristics, molecular epidemiology, and outcome of patients with clindamycin-resistant MRSA (n = 64) and clindamycin-susceptible MRSA (n = 554) were compared (including factors predictive of clindamycin-resistant MRSA SSTI). Patients with clindamycin-resistant MRSA were more likely to have had antibiotic exposure within 3 months (37.5% versus 17%, P < 0.01), surgery (25% versus 8%, P < 0.01), MRSA infection/colonization within 12 months (23% versus 7%, P < 0.01), or intravascular catheters (5% versus 0.5%, P = 0.02). On multivariate analysis, previous surgery (adjusted odds ratio [AOR] 2.97; 95% confidence interval [CI] 1.5-6.0), history of MRSA (AOR 3.4; 95% CI 1.7-7.1), and exposure to clindamycin (AOR 8.5; 95% CI 2.3-32) and to macrolides (AOR 7.2, 95% CI 1.6-31.8) were independently associated with presence of clindamycin-resistant MRSA. Clinical resolution was similar between groups (77% versus 68%; P = 0.26). Clindamycin-resistant MRSA was less often USA-300 (82% versus 98%, P = 0.004). Clindamycin resistance did not affect MRSA-SSTI clinical outcomes.

    Abstract The concurrent antineutrophil cytoplasmic antibody-associated glomerulonephritis (ANCA-GN) and membranous nephropathy (MN) have been increasingly documented, mainly in case studies and case series; however, the differences of clinical and pathologic characteristics as well as outcomes between ANCA-GN patients with and without MN remain unclear. The current study investigated the clinical and immunologic features of patients with combined ANCA-GN and MN in a large cohort. Twenty-seven of 223 patients had combined ANCA-GN and MN; they had significantly higher levels of initial serum creatinine, higher Birmingham Vasculitis Activity Score and poorer renal outcome than ANCA-GN patients without MN (P PLA2R antibodies and glomerular PLA2R deposits was significantly lower in patients with combined ANCA-GN and MN than that in patients with idiopathic MN (P < 0.05). Compared with the idiopathic MN patients, the patients with combined ANCA-GN and MN had significantly higher recognition frequency of immunoglobulin (Ig) G2 and IgG3, and significantly lower recognition frequency of IgG4 (P < 0.05). Patients with combined ANCA-GN and MN had distinct clinical features and a different pathogenesis of MN. PMID:26376387

    We conducted an evaluation of the intercamera (i.e., between cameras) variability in clinically relevant performance characteristics for Symbia gamma cameras (Siemens Medical Solutions, Malvern, PA) based on measurements made using nine separate systems. The significance of the observed intercamera variability was determined by comparing it to the intracamera (i.e., within a single camera) variability. Measurements of performance characteristics were based on the standards of the National Electrical Manufacturers Association and reports 6, 9, 22, and 52 from the American Association of Physicists in Medicine. All measurements were performed using 99mTc (except 57Co used for extrinsic resolution) and low-energy, high-resolution collimation. Of the nine cameras, four have crystals 3/8 in. thick and five have crystals 5/8 in. thick. We evaluated intrinsic energy resolution, intrinsic and extrinsic spatial resolution, intrinsic integral and differential flood uniformity over the useful field-of-view, count rate at 20% count loss, planar sensitivity, single-photon emission computed tomography (SPECT) resolution, and SPECT integral uniformity. The intracamera variability was estimated by repeated measurements of the performance characteristics on a single system. The significance of the observed intercamera variability was evaluated using the two-tailed F distribution. The planar sensitivity of the gamma cameras tested was found be variable at the 99.8% confidence level for both the 3/8-in. and 5/8-in. crystal systems. The integral uniformity and energy resolution were found to be variable only for the 5/8-in. crystal systems at the 98% and 90% confidence level, respectively. All other performance characteristics tested exhibited no significant variability between camera systems. The measured variability reported here could perhaps be used to define nominal performance values of Symbia gamma cameras for planar and SPECT imaging.

    The purpose of our study was (1) to analyze the flap tear location, direction of displacement and size on magnetic resonance (MR) imaging, (2) to describe associated knee abnormalities including presence of effusion, synovitis, bone marrow edema pattern or ligamentous tear, and (3) to assess clinical findings found with flap tears, including the pain score, and determine differences between operative and nonoperative groups. A retrospective radiology database search over the last 3 years identified 238 patients with flap tears, of which ultimately 58 with isolated flap tears were included after exclusion of patients with other significant knee internal derangement, severe degenerative change or prior surgery. MR studies of the knee were analyzed by two radiologists. Imaging characteristics were correlated with associated knee abnormalities and clinical findings. Statistical analysis employed linear and logistic regression models. Inter- and intrareader reliability was calculated. The medial meniscus was the most common site of flap tears (52/60, 87 %), with inferior displacement (47/60, 78 %). The degree of tibial cartilage loss had a positive correlation with the visual analog pain scale (p = 0.03). Patients who underwent arthroscopy were younger than those who did not (p = 0.01) and more likely to have a positive clinical McMurray test (p = 0.01). Medially and inferiorly displaced flap tears are the most common tear pattern. Those undergoing arthroscopy are more likely to have positive meniscal signs on clinical examination. A greater degree of cartilage loss involving the tibia on MR imaging was associated with increasing visual analog pain scores. (orig.)

    Full Text Available Abstract Background Platelet function disorders (PFDs have emerged as an important etiology of heavy menstrual bleeding (HMB in adolescents. However, neither clinical nor laboratory data have been methodically analyzed in this population subset. The objective of this study was to evaluate these parameters in order to distinguish characteristics of the disorder that in turn will lead to earlier diagnosis and therapy initiation. Methods Retrospective review of medical records from postmenarcheal adolescents with documented PFDs referred to a hemophilia treatment center and university faculty practices for bleeding diatheses with their clinical and laboratory data evaluated. Results Of 63 teens with documented PFDs, HMB was the most common clinical manifestation of PFD (43; 68.3%. Of these, 37 (86% were diagnosed with PFD either at or after menarche with the diagnosis based on HMB symptoms alone. Only 6 (14% were diagnosed with a PFD prior to menarche, based on associated bleeding, i.e., epistaxis, ecchymosis, and all developed HMB after menstruation onset. Interestingly, 20 girls were diagnosed with a PFD prior to menarche and of these, only 6 (30% went on to develop HMB after pubertal transition, while the majority (14; 70% did not. The average age-at-PFD diagnosis was 14.5yrs, significantly differing from the 10.9yrs average age-at-PFD diagnosis in their counterparts that, after menarche, did not develop HMB (PP P Conclusions Adolescents with PFDs and HMB appear to be clinically distinct from their non-HMB counterparts. This group of girls is characterized by HMB the major bleeding symptom, significantly high incidences of blood group O and the δ-SPD with a PFD diagnosed well after menarche. High false negative standard platelet function study results indicate additional diagnostic strategies, particularly for δ-SPD, should be considered.

    Aims Intraventricular conduction defects (IVCDs) can impair prognosis of heart failure (HF), but their specific impact is not well established. This study aimed to analyse the clinical profile and outcomes of HF patients with LBBB, right bundle branch block (RBBB), left anterior fascicular block (LAFB), and no IVCDs. Methods and results Clinical variables and outcomes after a median follow-up of 21 months were analysed in 1762 patients with chronic HF and LBBB (n = 532), RBBB (n = 134), LAFB (n = 154), and no IVCDs (n = 942). LBBB was associated with more marked LV dilation, depressed LVEF, and mitral valve regurgitation. Patients with RBBB presented overt signs of congestive HF and depressed right ventricular motion. The LAFB group presented intermediate clinical characteristics, and patients with no IVCDs were more often women with less enlarged left ventricles and less depressed LVEF. Death occurred in 332 patients (interannual mortality = 10.8%): cardiovascular in 257, extravascular in 61, and of unknown origin in 14 patients. Cardiac death occurred in 230 (pump failure in 171 and sudden death in 59). An adjusted Cox model showed higher risk of cardiac death and pump failure death in the LBBB and RBBB than in the LAFB and the no IVCD groups. Conclusion LBBB and RBBB are associated with different clinical profiles and both are independent predictors of increased risk of cardiac death in patients with HF. A more favourable prognosis was observed in patients with LAFB and in those free of IVCDs. Further research in HF patients with RBBB is warranted. PMID:23512097

    Full Text Available Background: The epidemiology and management of skin infections in nursing homes has not been adequately described. We reviewed the characteristics, diagnosis and treatment of skin infections among residents of nursing homes to identify opportunities to improve antibiotic use. Methods: A retrospective study involving 12 nursing homes in the Denver metropolitan area. For residents at participating nursing homes diagnosed with a skin infection between July 1, 2013 and June 30, 2014, clinical and demographic information was collected through manual chart review.Results: Of 100 cases included in the study, the most common infections were non-purulent cellulitis (n=55, wound infection (n=27, infected ulcer (n=8, and cutaneous abscess (n=7. In 26 cases, previously published minimum clinical criteria for initiating antibiotics (Loeb criteria were not met. Most antibiotics (n=52 were initiated as a telephone order following a call from a nurse, and 41 patients were not evaluated by a provider within 48 hours after initiation of antibiotics. Nearly all patients (n=95 were treated with oral antibiotics alone. The median treatment duration was 7 days (interquartile range [IQR] 7-10; 43 patients received treatment courses of ≥ 10 days.Conclusions: Most newly diagnosed skin infections in nursing homes were non-purulent infections treated with oral antibiotics. Antibiotics were initiated by telephone in over half of cases, and lack of a clinical evaluation within 48 hours after starting antibiotics was common. Improved diagnosis through more timely clinical evaluations and decreasing length of therapy are important opportunities for antibiotic stewardship in nursing homes.

    Full Text Available Background Down syndrome (DS is the most common chromosomal abnormality in newborns and is associated with other congenital malformations and health problems. The features of Down syndrome differ according to ethnicity and geographic region. Objectives The main aim was to assess the clinical characteristics of DS patients in a referral pediatric cardiology department. Patients and Methods In this cross-sectional study, we assessed the clinical characteristics of children with Down syndrome and heart defects in an educational hospital over 11 years (from September 2001 to September 2012 in Iran. All data were collected according to a checklist created by the researchers, which included the clinical information, genetic characteristics, cardiac and non-cardiac co-existing diseases, and parental variables of the children. An independent t-test and a chi-square test were used to compare qualitative variables such as birth weight and age of diagnosis. P < 0.05 was considered statistically significant. Results 100 patients with Down syndrome and congenital heart disease were evaluated; 52 were female (52% and 48 were male (48%. The average birth weight of the subjects was 2745 ± 523 (mean ± SD grams. The mean age of the patients’ mothers was 32 ± 6 years, and the mean age of the patients’ fathers was 36 ± 6 years. Chromosomal analysis was performed for 61 patients, 60 of whom had free trisomy (98.4%, one of whom had translocation (1.6%, and none of whom had a mosaic pattern of chromosomal abnormality. The parents of 33 the patients in this study were consanguineous. All patients had cardiac disorders, but non-cardiac disorder also was recorded in 37 patients (37%. The most common non-cardiac disorder in patients was hypothyroidism, and the second most common was gastrointestinal problems. Conclusions Parents were blood relatives in 33 (33% of the patient cases, which is a very high rate. Therefore, non-random mating is an important issue in

    Full Text Available Objective: To determine the epidemiological, clinical, laboratory characteristics as well as outcome of 411 patients with bowel obstruction in Southern Iran. Methods: This was a cross-sectional study being performed in Shahid Faghihi hospital of Shiraz between 2006 and 2012. We reviewed the medical charts of the 411 patients with initial diagnosis of bowel obstruction who were admitted to our center during the study period. The patients’ demographic, clinical and laboratory findings as well as their management and outcome was recorded in data gathering forms. The data were then analyzed according to the outcome and clinical characteristics. Results: Among the 411 patients with initial diagnosis of bowel obstruction, 253 (61.5% were men and 158 (38.5% were women. The mean age of the patients was 48.2±19.7 years. Besides, 73.6% were observed and 26.4% were operated. Those who were operated had those who underwent operation had significantly lower frequency of obstipation (28.1% vs. 71.9%; p=0.045 and abdominal distention (32.3% vs. 67.7%; p=0.007. Intraoperative findings included adhesion band formation in 50 (48.1%, mass 18 (17.3%, and hernia 7 (6.7%. We found that the frequency of malignancy was significantly higher in those who were managed conservatively compared to those undergoing operation (64.3% vs. 35.7%; p=0.042. The mean hospital stay was significantly higher in those who underwent operation (8.1±7.5 vs. 2.6±2.2 days; p=0.035. Conclusion: The results of this study demonstrates although some signs and symptoms, such as abdominal pain, vomiting, abdominal tenderness, abdominal distention, and obstipation, were more common among the patients with bowel obstruction, they were not sensitive and specific enough for definite diagnosis. Due to the lack of positive predictive value of clinical signs and symptoms in diagnosis of bowel obstruction, a reasonable and logical modality is needed for bowel obstruction diagnosis with better

    This study describes the clinical characteristics and examines hospital costs involved in the care of 117 patients undergoing Continuous Renal Replacement Therapy (CRRT) between January 1999 and August 2002. The majority (70.9%) of the patients undergoing CRRT expired in the hospital. Statistically significant differences were found with respect to the length of stay for discharge status and gender; and with respect to costs for surgery versus no surgery and gender. Significant differences were also found between discharge status and gender, age, and cardiovascular surgery. The results of this study raise economic and ethical questions related to the cost/benefit of CRRT and the futility of the treatment. Hospitals should ensure that they have utilization protocols in place for CRRT, promote cooperation between intensive care unit (ICU) physicians and nephrologists, and create multi-disciplinary CRRT teams in an effort to maximize the effectiveness of therapy and minimize costs.

    Although much investigation has been done with male sex offenders, there have been few studies on female sex offenders. Female sex offenders have been reported as having a high incidence of psychiatric disorders, but female paraphilics were rarely described. The literature on the treatment of female sex offenders is also limited and treatment with a selective serotonin reuptake inhibitor (SSRI) has not been reported. This paper presents the case of a woman with DSM-IV pedophilia. Her clinical characteristics, her offense history, and her positive response to treatment with sertraline (a SSRI) are described. This case adds to the limited literature on female pedophiles and suggests that SSRIs may be an effective treatment for paraphilic disorders in female sex offenders.

    Hepatitis B virus (HBV) infection is major global issue,because chronic HBV infection is strongly associatedwith liver cancer. HBV spread worldwide with variousmutations and variations. This variability, called quasispecies,is derived from no proof-reading capacity ofviral reverse transcriptase. So far, thousands of studiesreported that the variety of genome is closely related tothe geographic distribution and clinical characteristics.Recent technological advances including capillarysequencer and next generation sequencer have made ineasier to analyze mutations. The variety of HBV genomeis related to not only antigenicity of HBs-antigen but alsoresistance to antiviral therapies. Understanding of thesevariations is important for the development of diagnostictools and the appropriate therapy for chronic hepatitisB. In this review, recent publications in relation to HBVmutations and variations are updated and summarized.

    OBJECTIVE: The goal of this article was to describe the clinical characteristics and outcomes of patients diagnosed with psychogenic nonepileptic seizures (PNES). METHODS: We conducted a retrospective review of patients diagnosed with PNES in a 5-year period. RESULTS: Fifty patients with PNES were identified, giving an estimated incidence of 0.91\\/100,000 per annum. Thirty-eight were included for review, 15 of whom were male (39%). Eighteen patients had been diagnosed with epilepsy as well as PNES (47%). We demonstrated a gender difference in our patients, with males having higher seizure frequencies, more antiepileptic drug use, and a longer interval before diagnosis of PNES. Females were diagnosed with other conversion disorders more often than males. Impaired social function was observed in PNES, as was resistance to psychological interventions with a subsequent poor response to treatments. CONCLUSIONS: PNES remains a difficult condition to treat, and may affect males in proportions higher than those described in previous studies.

    Full Text Available Objective: To describe the epidemiological and clinical characteristics of fall injuries in East Azerbaijan, Iran. Methods: This cross-sectional study was based on Hospital Information System (HIS data for patients referred to the Imam Reza Hospital between 2008 and 2013. We recorded the demographic characteristics and epidemiological patterns of patients who were admitted to our center due to fall injuries. To standardize the reports the International Classification of Diseases (ICD, the International Classification of Diseases 9 Clinical Modification (ICD-9-CM was used. Equally, the hospitalization period and number, admission ward, and the final status of victims after discharge from the hospital were extracted from the HIS. Results: Overall we included a total number of 3397 patients with mean age of 39.2±22.7 years. There were 2501 (73.6% men among the patients. Long bone fracture (48.1% and intracranial injury (24.2% were the most frequent injuries among fall injury victims. Operations on spinal cord and spinal canal structures (12.0%, Operations on nose (11.6% were the most common operations being performed in these patients. The survival was significantly lower in patients with age more than 60 years when compared to other age groups ( p=0.001. The survival rate was significantly lower in age group of >60 years, compared to other age groups ( p=0.001. Conclusion: Given the high rate of fall injuries and death among the elderly that increases with age, appropriate measures must be taken to control and prevent injuries while prioritizing the elderly.

    Full Text Available Background: We sought to determine the clinical characteristics of pediatric esophagitis in southern Iran. Methods: This cross-sectional study was conducted over a 4-year period, from 2005 to 2009, in Nemazee Hospital, a tertiary healthcare center in Shiraz, southern Iran. We consecutively included all pediatric patients (<18 years who underwent endoscopy in our center and had pathology-confirmed diagnosis of esophagitis. Data regarding the patients’ demographic characteristics, comorbidities, and clinical findings were recorded using a questionnaire. All the patients underwent upper gastrointestinal endoscopy and biopsy of the esophagus, and the findings were recorded in the questionnaire. Results: We studied 125 children, comprising 61 (48.8% girls and 64 (51.2% boys at a mean age of 6.6±5.5 years. Repeated vomiting was the prominent symptom in our series, with it being reported by 75 (60% patients, followed by fever in 35 (28%. Erythema (33.6%, esophageal ulcer (11.2%, and whitish patch (8.0% were the most common endoscopic findings, while reflux esophagitis (32.8%, chronic (6.4% and acute esophagitis (5.6%, and candida esophagitis (5.6% were the most common histological diagnoses. Only one (0.8% patient was diagnosed as having eosinophilic esophagitis, aspergillosis, and graft-versus-host disease. Conclusion: Reflux was the most common cause of esophagitis in the pediatric population of southern Iran. Contrary to previous reports, the prevalence of eosinophilic esophagitis was far less than that estimated, while the prevalence of opportunistic infections was higher secondary to post-liver transplantation immunosuppression.

    The clinical characteristics of patients with disorders of sex development (DSD), and the diagnostic values of classic cytogenetic and molecular genetic assays for DSD were investigated. In the enrolled 56 cases, there were 9 cases of 46,XY DSD, 6 cases of Turner syndrome (TS), one case of Super female syndrome, 25 cases of Klinefelter syndrome, 14 cases of 46,XX DSD, and one case of autosomal balanced rearrangements with hypospadias. The diagnosis of sex was made through physical examination, cytogenetic assay, ultrasonography, gonadal biopsy and hormonal analysis. PCR was used to detect SRY, ZFX, ZFY, DYZ3 and DYZ1 loci on Y and X chromosomes respectively. The DSD patients with the same category had similar clinical characteristics. The karyotypes in peripheral blood lymphocytes of all patients were identified. PCR-based analysis showed presence or absence of the X/Y-linked loci in several cases. Of the 9 cases of 46,XY DSD, 6 were positive for SRY, 9 for ZFX/ZFY, 9 for DYZ3 and 8 for DYZ1 loci. Of the 6 cases of TS, only 1 case with the karyotype of 45,X,/46,XX/46,XY was positive for all 5 loci. Of the 25 cases of Klinefelter syndrome, all were positive for all 5 loci. In one case of rare Klinefelter syndrome variants azoospermia factor (AZF) gene detection revealed the loss of the AZFa+AZFb region. In 14 cases of 46,XX DSD, 7 cases were positive for SRY, 14 for ZFX, 7 for ZFY, 7 for ZYZ3, and 5 for DYZ1. PCR can complement and also confirm cytogenetic studies in the diagnosis of sex in cases of DSD.

    Full Text Available Objective: To determine the risk factors, clinical characteristics, surgical management and outcome of pseudoaneurysm secondary to iatrogenic or traumatic vascular injury. Methods: This was a cross-sectional study being performed in department of cardiovascular and thoracic surgery skims soura during a 4-year period. We included all the patients referring to our center with primary diagnosis of pseudoaneurysm. The pseudoaneurysm was diagnosed with angiography and color Doppler sonography. The clinical and demographic characteristics were recorded and the risk factors were identified accordingly. Patients with small swelling (less than 5-cm and without any complication were managed conservatively. They were followed for progression and development of complications in relation to swelling. Others underwent surgical repair and excision. The outcome of the patients was also recorded. Results: Overall we included 20 patients with pseudoaneurysm. The mean age of the patients was 42.1±0.6 years. Among them there were 11 (55% men and 9 (45% women. Nine (45% patients with end stage renal disease developed pseudoaneurysm after inadvertent femoral artery puncture for hemodialysis; two patients after interventional cardiology procedure; one after femoral embolectomy; one developed after fire arm splinter injury and one formed femoral artery related pseudoaneurysm after drainage of right inguinal abscess. The most common site of pseudoaneurysm was femoral artery followed by brachial artery. Overall surgical intervention was performed in 17 (85% patients and 3 (15% were managed conservatively. Conclusion: End stage renal disease is a major risk factor for pseudoaneurysm formation. Coagulopathy, either therapeutic or pathological is also an important risk factor. Patients with these risk factors need cannulation of venous structures for hemodialysis under ultrasound guide to prevent inadvertent arterial injury. Patients with end stage renal disease who

    The aim of this study was to describe the clinical characteristics of foot ulceration in patients with rheumatoid arthritis (RA). Adults with RA and current foot ulceration but without diabetes were recruited. Clinical examination included assessment of RA disease activity, foot deformity, peripheral vascular disease, neuropathy and plantar pressures. Location, wound characteristics and time to healing were recorded for each ulcer. Participants completed the Health Assessment Questionnaire and Leeds Foot Impact Scale. Thirty-two cases with 52 current ulcers were recruited. Thirteen patients (41%) experienced more than one current ulcer: 5 (16%) had bilateral ulceration, 15 (47%) had previous ulceration at a current ulcer site. The majority (n = 33) of open ulcers were located over the dorsal aspect of the interphalangeal joints (n = 12), plantar aspect of the metatarsophalangeal joints (MTPJs) (n = 12) and medial aspect of first MTPJs (n = 9). In ulcerated limbs (n = 37), ankle brachial pressure index (ABPI) was plantar pressures were >6 kg/cm(2) in 6 (16%). Mean ulcer size was 4.84 by 3.29 mm. Most ulcers (n = 42, 81%) were superficial; five (9.6%) were infected. Time to healing was available for 41 ulcers: mean duration was 28 weeks. Three ulcers remained open. In conclusion, foot ulceration in RA is recurrent and multiple ulcers are common. Whilst ulcers are small and shallow, time to achieve healing is slow, posing infection risk. Reduced protective sensation is common in affected patients. The prevalence of arterial disease is low but may be under estimated due to high intolerance of ABPI.

    Full Text Available Abstract Background A waterborne outbreak of Giardia lamblia gastroenteritis led to a high prevalance of long-lasting fatigue and abdominal symptoms. The aim was to describe the clinical characteristics, disability and employmentloss in a case series of patients with Chronic Fatigue Syndrome (CFS after the infection. Methods Patients who reported persistent fatigue, lowered functional capacity and sickness leave or delayed education after a large community outbreak of giardiasis enteritis in the city of Bergen, Norway were evaluated with the established Centers for Disease Control and Prevention criteria for CFS. Fatigue was self-rated by the Fatigue Severity Scale (FSS. Physical and mental health status and functional impairment was measured by the Medical Outcome Severity Scale-short Form-36 (SF-36. The Hospital Anxiety and Depression Scale (HADS was used to measure co-morbid anxiety and depression. Inability to work or study because of fatigue was determined by sickness absence certified by a doctor. Results A total of 58 (60% out of 96 patients with long-lasting post-infectious fatigue after laboratory confirmed giardiasis were diagnosed with CFS. In all, 1262 patients had laboratory confirmed giardiasis. At the time of referral (mean illness duration 2.7 years 16% reported improvement, 28% reported no change, and 57% reported progressive course with gradual worsening. Mean FSS score was 6.6. A distinctive pattern of impairment was documented with the SF-36. The physical functioning, vitality (energy/fatigue and social functioning were especially reduced. Long-term sickness absence from studies and work was noted in all patients. Conclusion After giardiasis enteritis at least 5% developed clinical characteristics and functional impairment comparable to previously described post-infectious fatigue syndrome.

    Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis.

    Full Text Available Aim: Our aim was to identify the characteristics of the patient that performed upper gastrointestinal endoscopy in a new established endoscopy unit of a state hospital. We want to present the spectrum of gastrointestinal diseases in our hospitals region. Material and Method: We analyzed patients upper endoscopy results according to age, sex, complaints, clinical characteristics, type of anesthesia, and the necessity of biopsy. We reviewed 256 patients data between 2013 December-2014 July. All endoscopies were performed by same surgeon. Results: The highest complaint was epigastric pain (n=112, 43, 8%. Other complaints were followed as dyspepsia (n=84, 32.8%, heartburn (n=42, 16.4%, nausea (n=4, 1.6%, vomiting (n=2, 0.8%, dysphagia (n=6, 2.3%. We determined 218 gastritis (85.2%, 64 hiatal hernia (25%, 120 esophagitis (46.9%, 76 duodenitis (29.7%, 4 gastric ulcer (1.6%, 18 duodenal ulcers (7%, 20 bile reflux (7.8%, 26 Gastro esophageal reflux disease (GERD in patients (10.2%. 10 patients reported as normal (3.9%. Biopsy was performed in 186 of the patients. Discussion: Endoscopy can become an early diagnostic examination by increasing the availability of endoscopy. Also alarm symptoms should not be ignored and endoscopy should perform immediately in symptomatic patients. As an early result of upper gastrointestinal endoscopies that performed in this study; gastritis, esophagitis, duodenitis and hiatal hernia are common gastrointestinal diseases in our region.

    Full Text Available Abstract Background Systemic anaplastic large cell lymphoma (S-ALCL is a rare disease with a highly variable prognosis and no standard chemotherapy regimen. Anaplastic lymphoma kinase (ALK has been reported as an important prognostic factor correlated with S-ALCL in many but not all studies. In our study, we retrospectively analyzed 92 patients with S-ALCL from the Peking University Lymphoma Center for clinical and molecular prognostic factors to make clear the role of ALK and other prognostic factors in Han Chinese S-ALCL. Results The majority of Chinese S-ALCL patients were young male patients (median age 26, male/female ratio 1.7 and the median age was younger than previous reports regardless of ALK expression status. The only statistically significant different clinical characteristic in S-ALCL between ALK positive (ALK+ and ALK negative (ALK- was age, with a younger median age of 22 for ALK+ compared with 30 for ALK-. However, when pediatric patients (≤18 were excluded, there was no age difference between ALK+ and ALK-. The groups did not differ in the proportion of males, those with clinical stage III/IV (49 vs 51% or those with extranodal disease (53 vs 59%. Of 73 evaluable patients, the 3-year and 5-year survival rates were 60% and 47%, respectively. Univariate analysis showed that three factors: advanced stage III/IV, lack of expression of ALK, and high Ki-67 expression, were associated with treatment failure in patients with S-ALCL. However, ALK expression correlated with improved survival only in patients younger than 14 years, while not in adult patients. In multivariate analysis, only clinical stage was an independent prognostic factor for survival. Expressions of Wilms tumor 1 (WT1 and B-cell lymphoma 2 protein (BCL-2 correlated with the expression of ALK, but they did not have prognostic significance. High Ki-67 expression was also a poor prognostic factor. Conclusions Our results show that ALK expression alone is not

    Full Text Available Giant cell tumor of bone accounts for about 5% of all primary bone tumors in adults and is still one of the most obscure and intensively examined tumors of bone. This largely results from the lack of uniform clinical, radiographic, histological or morphological aspects that allow prediction of recurrence. Classified by the World Health Organization as “an aggressive, potentially malignant lesion”, the giant cell tumor of bone could give lung metastases, could undergo malignant degeneration or could have multicentric localization. It usually develops in long bones but can also occur in unusual locations. The common presenting symptom is increasing pain at the tumor site. Standard treatment ranges from curettage to wide resection, with reports of varying oncological and functional results. The recurrence rate is high during the first 2-3 years after surgery regardless of pre-operative tumor stage. Herein, we discuss the morphological, clinical, radiological, and therapeutic characteristics of this pathologic entity as well as its differential diagnosis. J Clin Exp Invest 2014; 5 (3: 475-485

    Due to the specific physiology associated with pregnancy and puerperium, cerebral venous sinus thrombosis (CVT) may manifest different characteristics. This study aimed to identify the clinical manifestations and prognosis of pregnancy-associated CVT. A total of 43 pregnancy-associated CVT patients were enrolled. We analysed the clinical presentations of the disease and performed a multivariate logistic regression analysis to determine which variables were associated with prognosis. Our descriptive results showed the following: 1) the incidence was 202 per 100,000 deliveries, and the mortality rate was 11.63%; 2) the most frequent symptom was headache; 3) the most frequent abnormal laboratory findings were increased levels of fibrinogen and several serum lipoproteins (including triglyceride, cholesterol, high-density lipoprotein, low-density lipoprotein, apolipoprotein A1, and apolipoprotein B); and 4) the superior sagittal sinus and transverse sinus were the most frequently affected locations. Moreover, an increased modified Rankin Scale score was positively associated with infection, seizure, intracerebral haemorrhage (ICH) and hypertensive disorders of pregnancy (HDP). Comparably, the occurrence of death was positively and significantly associated with infection, seizure and ICH. Consequently, timely diagnosis and treatment of pregnancy-associated CVT patients with infection, seizure, ICH or HDP are needed. Patients with infection, seizure or ICH have a greater risk of death.

    Lung sounds provide useful information for assessing and monitoring respiratory patients, but standard auscultation is subjective. Computer aided lung sound analysis (CALSA) enables the quantification and characterisation of added lung sounds (e.g. crackles). At present, little is known about the reliability of these sound characteristics. Therefore, the aim of this study was to explore the reliability of crackle initial deflection width (IDW) and two-cycle deflection (2CD) in a clinical population. Fifty-four subjects (37 bronchiectasis, 17 cystic fibrosis) were recruited from out-patient clinics. Three repeated lung sound recordings were taken at seven anatomical sites with a digital stethoscope connected to a laptop computer. The intra-subject reliability of crackle IDW and 2CD was found to be 'good' to 'excellent', estimated by the analysis of variance, intraclass correlation coefficient (IDW 0.76;0.85, 2CD 0.83;0.94), Bland and Altman 95% limits of agreement (IDW -0.50;0.47 ms, 2CD -2.12;1.87 ms) and smallest real difference (IDW 0.30;0.66 ms, 2CD 1.57;2.42 ms). Crackle 2CD was found to be more reliable than IDW. It is concluded that crackle IDW and 2CD characterized by CALSA have good test-retest reliability. This technique requires further evaluation since CALSA has potential to diagnose or monitor respiratory conditions, and provide an objective physiological measure for respiratory interventions.

    INTRODUCTION: Stenotrophomonas maltophilia earlier had limited pathogenic potential, but now with growing degree of immunosuppression in general population, it is being recognized as an important nosocomial pathogen. METHODOLOGY: A retrospective 7 years study was carried out to determine the clinical characteristics of all patients with Stenotrophomonas infections, antibiotic resistance pattern, and risk factors associated with hospital mortality. All patients with Stenotrophomonas culture positivity were identified and their medical records were reviewed. Risk factor associated with hospital mortality was analyzed. RESULTS: A total of 123 samples obtained from 88 patients were culture positive. Most patients presented with bacteremia (45, 51%) followed by pneumonia (37, 42%) and skin and soft tissue infections (6, 7%). About 23 of 88 Stenotrophomonas infected patients had co-infection. Percentage resistance to cotrimoxazole; 8 (5.4%) was lower than that for levofloxacin; 18 (12%). Twenty-eight patients died during hospital stay. Intensive Care Unit admission (P = 0.0002), mechanical ventilation (P = 0.0004), central venous catheterization (P = 0.0227), urethral catheterization (P = 0.0484), and previous antibiotic intake (P = 0.0026) were independent risk factors associated with mortality. CONCLUSION: Our findings suggest that Stenotrophomonas can cause various infections irrespective of patient's immune status and irrespective of potential source. Thus, Stenotrophomonas should be thought of as potential pathogen and its isolation should be looked with clinical suspicion.

    2013-08-01

    Full Text Available Background: The most common genetic cause of frontotemporal lobar degeneration (FTLD and amyotrophic lateral sclerosis (ALS has been linked to a hexanucleotide repeat expansion in the C9ORF72 gene. The frequency of the C9ORF72 expansion in Finland is among the highest in the world. Methods: We assessed 73 Finnish patients with FTLD in order to examine the clinical characteristics associated with the expanded C9ORF72. Demographic and clinical features were evaluated. As a potential disease modifier, the apolipoprotein E (APOE genotype was also assessed. Neuropathological analysis was available on 2 expansion carriers and 1 non-carrier. Results: The C9ORF72 expansion was present in 20 of 70 (29% probands. Significant associations with the C9ORF72 expansion were observed for concomitant ALS and positive family history of dementia or ALS. Psychoses were detected in both carriers and non-carriers (21 vs. 10%, p = 0.25. The APOE ε4 allele did not cluster among expansion carriers. Numerous p62-positive neuronal inclusions were detected in the cerebellar cortex of the 2 expansion carriers. Conclusion: In line with the suggested C9ORF72 core phenotype, we also detected a high frequency of neuropsychiatric symptoms; however, these symptoms seem not be specific to C9ORF72-associated FTLD. FTLD should be considered in cases of middle-age-onset psychosis.

    Full Text Available Peroxisomal disorders are a group of genetically heterogeneous metabolic diseases related to dysfunction of peroxisomes. Dysmorphic features, neurological abnormalities, and hepatic dysfunction can be presenting signs of peroxisomal disorders. Here we presented dysmorphic facial features and other clinical characteristics in two patients with PEX1 gene mutation. Follow-up periods were 3.5 years and 1 year in the patients. Case I was one-year-old girl that presented with neurodevelopmental delay, hepatomegaly, bilateral hearing loss, and visual problems. Ophthalmologic examination suggested septooptic dysplasia. Cranial magnetic resonance imaging (MRI showed nonspecific gliosis at subcortical and periventricular deep white matter. Case II was 2.5-year-old girl referred for investigation of global developmental delay and elevated liver enzymes. Ophthalmologic examination findings were consistent with bilateral nystagmus and retinitis pigmentosa. Cranial MRI was normal. Dysmorphic facial features including broad nasal root, low set ears, downward slanting eyes, downward slanting eyebrows, and epichantal folds were common findings in two patients. Molecular genetic analysis indicated homozygous novel IVS1-2A>G mutation in Case I and homozygous p.G843D (c.2528G>A mutation in Case II in the PEX1 gene. Clinical findings and developmental prognosis vary in PEX1 gene mutation. Kabuki-like phenotype associated with liver pathology may indicate Zellweger spectrum disorders (ZSD.

    Full Text Available Objective. To describe the demographic and clinical characteristics of HIV-infected individuals and HIV-affected couples who were referred for preconception counseling (PCC at a large urban US-based HIV clinic. Methods. Electronic medical records were reviewed for HIV-infected individuals and HIV-affected couples. Medical, reproductive, surgical, psychosocial, and family history data were abstracted. Univariate analyses were done. Results. There were 8 single HIV-infected women and 100 HIV-affected couples who underwent PCC. HIV-infected women were older (mean age 35 years versus 32 years, P=0.06, were more likely to smoke (23% versus 0%, P<0.01, and had more medical comorbidities (57% versus 33%, P=0.04 than HIV-uninfected women. The majority of couples were serodiscordant (77%, and of these couples, 32% had a detectable plasma viral load and 33% report inconsistent condom use. Conclusions. HIV-infected women have a number of medical and psychosocial issues, including those related to HIV that may increase the risk of adverse pregnancy outcomes and HIV perinatal and sexual transmission. PCC is an important intervention to optimize maternal management to improve perinatal outcomes and minimize transmission risks.

    Myeloid neoplasms with eosinophilia and abnormalities of PDGFRB gene are a new kind of myeloid disorders in the revised 2008 WHO classification. Out of detected 2000 cases of myeloid cell abnormalities in our hospital, 12 cases of myeloid neoplasms with eosinophilia and abnormalities of PDGFRB were found. This study was purposed to summarize and analyze the clinical and laboratorial characteristics of the 12 cases with PDGFRB gene abnormalities. The results indicated that among 12 cases of myeloid neoplasms with PDGFRB abnormalities, 5 cases with TEL/PDGFRB fusion gene, 2 cases with HEPI/PDGFRB, 1 case with PDGFRB mutation, 1 case with RABAPTIN-5/PDGFRB, 1 case with GIT2/PDGFRB, 1 case with TP53/PDGFRB, 1 case with WDR43/PDGFRB fusion gene were detected, showing the polymorphism of PDGFRB gene abnormalities. Among this kind of myeloid neoplasm patients, almost all patients manifested monocytosis and eosinophilia in different degree, the thrombocytosis mainly was observed in atypical myeloid neoplasms, acute leukemia, chromic myelo-monocytic leukemia patients. The treatment with imatinib mesylate for this kind of patients was effective in some cases. It is concluded that the myeloid neoplasms with PDGFRB gene abnormalities are a kind of heterogenetic myeloid neoplasms, their gene abnormal types and clinical manifestations show polymorphism too. The monocytosis and eosinophilia appear in this kind myeloid neoplasms which may be treated with tyrosine kinase inhibitors such as imatinib mesylate.

    Full Text Available AbstractObjective: To describe the clinical characteristics, lung function, radiological findings, and the inflammatory cell profile in induced sputum in children and adolescents with severe therapy-resistant asthma (STRA treated at a referral center in southern Brazil.Methods: We retrospectively analyzed children and adolescents (3-18 years of age with uncontrolled STRA treated with high-dose inhaled corticosteroids and long-acting β2 agonists. We prospectively collected data on disease control, lung function, skin test reactivity to allergens, the inflammatory cell profile in induced sputum, chest CT findings, and esophageal pH monitoring results.Results: We analyzed 21 patients (mean age, 9.2 ± 2.98 years. Of those, 18 (86% were atopic. Most had uncontrolled asthma and near-normal baseline lung function. In 4 and 7, induced sputum was found to be eosinophilic and neutrophilic, respectively; the inflammatory cell profile in induced sputum having changed in 67% of those in whom induced sputum analysis was repeated. Of the 8 patients receiving treatment with omalizumab (an anti-IgE antibody, 7 (87.5% showed significant improvement in quality of life, as well as significant reductions in the numbers of exacerbations and hospitalizations.Conclusions: Children with STRA present with near-normal lung function and a variable airway inflammatory pattern during clinical follow-up, showing a significant clinical response to omalizumab. In children, STRA differs from that seen in adults, further studies being required in order to gain a better understanding of the disease mechanisms.

    Polymyalgia rheumatica (PMR) is a common inflammatory disease of the elderly in western countries, but the prevalence is apparently different between races and countries. Until now, an epidemiologic study of PMR is limited in Korea. We retrospectively evaluated the clinical data of 78 patients with PMR who were treated in 5 tertiary hospitals, and analyzed initial laboratory data, symptoms, therapeutic responses, and prognostic factors for relapse 1 year after treatments. Sixty percent of patients had pain in both shoulder and hip girdles with 10.6 weeks of duration, 75.9 ± 32.7 mm/h of erythrocyte sedimentation rate (ESR), and 6.2 ± 6.4 mg/dl of C-reactive protein. The rate of relapse and remission at 1 year was 38.4 and 2.5 %, respectively. The rate of overall relapse was 46.1 %, and the relapse occurred mostly in a year, especially between 6 and 12 months after diagnosis. There were more female in relapse group (88.9 %, p = 0.037), and cumulative steroid dose of 1 year was significantly higher in relapse group (5.5 ± 2.7 vs. 4.4 ± 2.5 g, p = 0.018). Independent risk factors for relapse were initial CRP ≥ 2.5 mg/dl (OR 6.296, p = 0.047) and the use of hydroxychloroquine (OR 6.798, p = 0.035). Initial dosage or tapering speed of steroid did not influence on prognosis. In Korean patients with PMR, baseline clinical characteristics and relapse rate were similar to previous studies, but our patients accompanied no giant cell arteritis and showed lower remission rate as well as delayed therapeutic response and later occurrence of relapse. More aggressive management would be needed according to the clinical status of patients.

    BACKGROUND Several acute complications related to takotsubo cardiomyopathy (TTC) have been documented recently. However, the incidence and clinical significance of acute thromboembolic events in TTC is not well established. METHODS A detailed investigation of the clinical characteristics and in-hospital complications of 114 consecutive patients diagnosed with TTC between January 2003 and September 2015 was carried out. This study was initiated to reveal the predictors, clinical significance, and short-term and long-term outcomes of patients with TTC associated with acute thromboembolic events on index presentation. RESULTS The incidence of acute thromboembolic events related to TTC was around 12.2%, and these included ventricular thrombi, cerebrovascular events, retinal and brachial artery pathologies, renal, splenic, and aortic involvement. The most frequent complication on initial presentation was cardiogenic shock (20%) accompanied with pulmonary congestion (20%). Interestingly, patients experiencing thromboembolic events had higher C-reactive protein (CRP) levels as compared to the non-thromboembolic group (P = 0.02). Certain thromboembolic events were characterized by the presence of ST-segment elevation in electrocardiogram (P = 0.02). Chest pain was the primary symptom in these patients (P = 0.09). Furthermore, there was significant right ventricular involvement (as assessed by transthoracic echocardiography) in patients presenting with an acute thromboembolic event (P = 0.08). A Kaplan–Meier analysis indicated a significantly higher mortality rate over a mean follow-up of three years in the thromboembolic group than the non-thromboembolic group (log-rank, P = 0.02). CONCLUSIONS Our results confirmed the relative common occurrence of thromboembolic events in the setting of TTC. Inflammation might play an important role in the development of thromboembolic events, and a right ventricular involvement and ST-segment elevation could be positive predictors for

    Background Few studies have comprehensively described tropical respiratory disease surveillance in military populations. There is also a lack of studies comparing clinical characteristics of the non-influenza pathogens with influenza and amongst themselves. Methods From May 2009 through October 2012, 7733 consenting cases of febrile respiratory illness (FRI) (temperature [greater than or equal to]37.5degreesC with cough or sorethroat) and controls in the Singapore military had clinical data and nasal washes collected prospectively. Nasal washes underwent multiplex PCR, and the analysis was limited to viral mono-infections. Results 49% of cases tested positive for at least one virus, of whom 10% had multiple infections. 53% of the FRI cases fulfilled the definition of influenza-like illness (ILI), of whom 52% were positive for at least one virus. The most frequent etiologies for mono-infections among FRI cases were Influenza A(H1N1)pdm09 (13%), Influenza B (13%) and coxsackevirus (9%). The sensitivity, specificity, positive predictive value and negative predictive value of ILI for influenza among FRI cases were 72%, 48%, 40% and 69% respectively. On logistic regression, there were marked differences in the prevalence of different symptoms and signs between viruses with fever more prevalent amongst influenza and adenovirus infections than other viruses. Conclusion There are multiple viral etiologies for FRI and ILI with differing clinical symptoms in the Singapore military. Influenza and coxsackevirus were the most common etiology for FRI, while influenza and adenoviruses displayed the most febrile symptoms. Further studies should explore these differences and possible interventions. PMID:24735158

    Full Text Available Introduction : Diabetes mellitus (DM has a national prevalence near 4.2% and the worldwide fluctuates between 2 and 5%. The complications are caused by poor metabolic control and hence also by the poor management of cardiovascular risk factors (CVRF, hence the importance of managing and reducing the CVRF, the main objective of control programs for DM. AIM: To characterize clinically to patients with DM2 who were cared for in the agenda of cardiovascular CESFAM Chiguay (commune of Chiguayante, region of Bio Bio during the first 9 months of 2008. PATIENT and method S: Observational descriptivestudy, non-probability sampling a retrospective study was observational and descriptive, reviewing the ballots of each tabcontrol chronic clinic patients enrolled in the program Cardiovascular(VCP from January to September 2008 in CESFAM “Chiguay.” Results : The study included 332 patients, of whom 67.77% were women and 32.23% men. Average age was 63.6 years. 47.59% were obese. 49.39% had a HbA1c levels at about 7%. 21.69% had an “optimal” control of LDL. 56.93% had blood pressure poorly controlled. Discussion : The most noticeable clinical and epidemiological characteristics of the diabetes type 2 found in our study were late aged dominance in females and obese. Almost 80% of the cases had higher levels of LDL and only around a half had good metabolic control, with HbA1c under7%. This could be explained because the studied subjects belongedmostly to a low socioeconomic status, which would lead to unbalanced diet, poor adherence to the treatment and poor understanding of their pathology.

Materials and Methods: Prospective study of 30 patients with symptoms of CTS, attending to the Neurology out patient department (OPD at University Teaching Hospital. A multidimensional assessment of CTS was done using historic and objective scale (Hi-Ob scale for clinical severity, Boston carpal tunnel questionnaire (BCTQ for patient-oriented measures, neuro physiologic studies of median nerve at wrist and USG to measure median nerve CSA at carpal tunnel inlet. Results: Thirty patients included in the study (22 women and 8 men. Mean of CSA was 12.69 mm 2 (SD2.67. Association between BCTQ score value and inlet values was assessed by Karl Pearson correlation coefficient ( r = 0.376, P = 0.04. There was positive association with BCTQ scores and CSA of median nerve at carpal tunnel inlet. To compare clinical severity scale (Hi-Ob and USG CSA, analysis of variance was performed (F value and Scheffe′s multiple comparison test was used to find group difference (grades 1 and 2 P < 0.001, grades1 and 2P P < 0.001, grade 2 differs with grade 2P P < 0.006. As the number of patients is less in minimal, mild and severe groups, the difference between neurophysiological groups and mean of CSA was not statistically significant. Conclusion: A positive correlation exists between USG findings and all the conventional measures of CTS severity.

    Full Text Available Background and Design: Occupational contact dermatitis (OCD is responsible for 80-90% of the occupational dermatoses. The aim of this work was to evaluate the clinical features of patients with OCD admitted to our hospital. Materials and Methods: The records of patients, who were admitted to our hospital with OCD between December 2009 and January 2013, were evaluated retrospectively. One hundred fifty-nine patients, who were diagnosed with OCD according to the Mathias criteria, were included in the study. Age, sex, location of the lesions, atopic status, glove use, occupational exposure time and total IgE levels of the patients were assessed. Patients with positive allergic reaction with "European Standard Series Skin Patch Test" were identified as allergic OCD and patients with negative test results as "irritant OCD". The clinical features and patch results of patients are evaluated. Results: One hundred fifty-nine patients with a mean age of 39±7.9 years consisted of 151 men and 8 women. The hands were the most common site of OCD; the palms were the most common affected areas of hand eczema. Eighty-one patients (50.1% were identified to have allergic OCD and 78 (49.9% as irritant OCD. Irritant OCD was most commonly seen in dental technicians, whereas allergic OCD was most commonly seen in tailors. The top 3 most frequent allergens were potassium dichromate (15.1%, nickel sulfate (9.11% and cobalt chloride (10.7%. Conclusion: In our country, there has been no comprehensive study presenting the clinical and descriptive characteristics of OCD. For preventing OCD and reducing sick leave we need to have data that belong to our country. Consequently, multicenter studies should be performed for establishing our own database on OCD.

    Introduction Severe right ventricular hypertrophy (SRVH) is a rare phenotype in hypertrophic cardiomyopathy (HCM) for which limited information is available. This study was undertaken to investigate the clinical, prognostic and genetic characteristics of HCM patients with SRVH. Methods HCM with SRVH was defined as HCM with a maximum right ventricular wall thickness ≥10 mm. Whole-genome sequencing (WGS) was performed in HCM patients with SRVH. Multivariate Cox proportional hazards regression models were used to identify risk factors for cardiac death and events in HCM with SRVH. Patients with apical hypertrophic cardiomyopathy (ApHCM) were selected as a comparison group. The clinical features and outcomes of 34 HCM patients with SRVH and 273 ApHCM patients were compared. Results Compared with the ApHCM group, the HCM with SRVH group included younger patients and a higher proportion of female patients and also displayed higher cardiovascular morbidity and mortality. The multivariate Cox proportional hazards regression models identified 2 independent predictors of cardiovascular death in HCM patients with SRVH, a New York Heart Association class ≥III (hazard ratio [HR] = 8.7, 95% confidence interval (CI): 1.43-52.87, p = 0.019) and an age at the time of HCM diagnosis ≤18 (HR = 5.5, 95% CI: 1.24-28.36, p = 0.026). Among the 11 HCM patients with SRVH who underwent WGS, 10 (90.9%) were identified as carriers of at least one specific sarcomere gene mutation. MYH7 and TTN mutations were the most common sarcomere mutations noted in this study. Two or more HCM-related gene mutations were observed in 9 (82%) patients, and mutations in either other cardiomyopathy-related genes or ion-channel disease-related genes were found in 8 (73%) patients. Conclusions HCM patients with SRVH were characterized by poor clinical outcomes and the presentation of multiple gene mutations. PMID:28323875

    Urinary tract infections (UTI) cause a great number of morbidity and mortality. These infections are serious complications in pregnancy, patients with diabetes, polycystic kidneys disease, sickle cell anaemia, kidney transplant and in patients with functional or structural anomalies of the urinary tract. The aim of this investigation was to determine a dominant causative agents of UTI and some of the clinical and laboratory characteristics of acute community-acquired UTI in adult hospitalised patients. We studied 200 adult patients with acute community-acquired UTI hospitalised in the Clinic for Infectious Diseases Tuzla from January 2006 to December 2007. The patients were divided into two groups: a group of patients with E. coli UTI (147) and a group of patients with non-E. coli UTI (53). In these two groups, the symptoms and signs of illness, blood test and urine analysis results were analysed. Our results have shown that the patients with E. coli UTI frequently had fever higher than 38,5 degrees C (p<0,0001), chills (p=0,0349), headache (p=0,0499), cloudy urine (p<0,0001), proteinuria (p=0,0011) and positive nitrite-test (p=0,0002). The patients with non-E. coli UTI frequently had fever lower than 38,5 degrees C (p<0,0001) and urine specific gravity <1015 (p=0,0012). There was no significant difference in blood test results between patients with E. coli and non-E. coli UTI. These clinical and laboratory findings can lead us to early etiological diagnosis of these UTI before urine culture detection of causative agents, which takes several days. Early etiological diagnosis of the E. coli and non-E. coli UTI is necessary for an urgent administration of appropriate empirical antibiotic treatment. This is very important in prevention of irreversible kidney damage, prolonged treatment, complications, as well as recidives and chronicity of the illness.

    The lack of epidemiologic data on invasive Streptococcus pyogenes infections in many developing countries is concerning, as S. pyogenes infections are commonly endemic in these areas. Here we present the results of the first prospective surveillance study of invasive Streptococcus pyogenes infections in India. Fifty-four patients with invasive S. pyogenes infections were prospectively enrolled at two study sites, one in the north and one in the south of India. Sterile-site isolates were collected, and clinical information was documented using a standardized questionnaire. Available acute-phase sera were tested for their ability to inhibit superantigens produced by the patient's own isolate using a cell-based neutralizing assay. The most common clinical presentations were bacteremia without focus (30%), pneumonia (28%), and cellulitis (17%). Only two cases of streptococcal toxic shock syndrome and no cases of necrotizing fasciitis were identified. Characterization of the isolates revealed great heterogeneity, with 32 different emm subtypes and 29 different superantigen gene profiles being represented among the 49 sterile-site isolates. Analyses of acute-phase sera showed that only 20% of the cases in the north cohort had superantigen-neutralizing activity in their sera, whereas 50% of the cases from the south site had neutralizing activity. The results demonstrate that there are important differences in both clinical presentation and strain characteristics between invasive S. pyogenes infections in India and invasive S. pyogenes infections in Western countries. The findings underscore the importance of epidemiologic studies on streptococcal infections in India and have direct implications for current vaccine developments.

    AIM: To evaluate the prevalence of upper gastrointestinal symptoms and their association with clinical and functional characteristics in elderly outpatients. METHODS: The study involved 3238 outpatients ≥ 60 years consecutively enrolled by 107 general practitioners. Information on social, behavioral and demographic characteristics, function in the activities of daily living (ADL), co-morbidities and drug use were collected by a structured interview. Upper gastrointestinal symptom data were collected by the 15-items upper gastro-intestinal symptom questionnaire for the elderly, a validated diagnostic tool which includes the following five symptom clusters: (1) abdominal pain syndrome; (2) reflux syndrome; (3) indigestion syndrome; (4) bleeding; and (5) non-specific symptoms. Presence and severity of gastrointestinal symptoms were analyzed through a logistic regression model. RESULTS: 3100 subjects were included in the final analysis. The overall prevalence of upper gastrointestinal symptoms was 43.0%, I.e. Cluster (1) 13.9%, (2) 21.9%, (3) 30.2%, (4) 1.2%, and (5) 4.5%. Upper gastrointestinal symptoms were more frequently reported by females (P < 0.0001), with high number of co-morbidities (P < 0.0001), who were taking higher number of drugs (P < 0.0001) and needed assistance in the ADL. Logistic regression analysis demonstrated that female sex (OR = 1.39, 95% CI: 1.17-1.64), disability in the ADL (OR = 1.47, 95% CI: 1.12-1.93), smoking habit (OR = 1.29, 95% CI: 1.00-1.65), and body mass index (OR = 1.06, 95% CI: 1.04-1.08), as well as the presence of upper (OR = 3.01, 95% CI: 2.52-3.60) and lower gastroenterological diseases (OR = 2.25, 95%CI: 1.70-2.97), psychiatric (OR = 1.60, 95% CI: 1.28-2.01) and respiratory diseases (OR = 1.25, 95% CI: 1.01-1.54) were significantly associated with the presence of upper gastrointestinal symptoms. CONCLUSION: Functional and clinical characteristics are associated with upper gastrointestinal symptoms. A multidimensional

    The association between autism spectrum disorder (ASD) and epilepsy has been described for decades, and yet we still lack the full understanding of this relationship both clinically and at the pathophysiologic level. This review evaluates the available data in the literature pertaining to the clinical characteristics of patients with autism spectrum disorder who develop epilepsy and, conversely, patients with epilepsy who develop autism spectrum disorder. Many studies demonstrate an increased risk of epilepsy in individuals with ASD, but rates vary widely. This variability is likely secondary to the different study methods employed, including the study population and definitions of the disorders. Established risk factors for an increased risk of epilepsy in patients with ASD include intellectual disability and female gender. There is some evidence of an increased risk of epilepsy associated with other factors such as ASD etiology (syndromic), severity of autistic features, developmental regression, and family history. No one epilepsy syndrome or seizure type has been associated, although focal or localization-related seizures are often reported. The age at seizure onset can vary from infancy to adulthood with some evidence of a bimodal age distribution. The severity and intractability of epilepsy in populations with ASD have not been well studied, and there is very little investigation of the role that epilepsy plays in the autism behavioral phenotype. There is evidence of abnormal EEGs (especially epileptiform abnormalities) in children with ASD even in the absence of clinical seizures, but very little is known about this phenomenon and what it means. The development of autism spectrum disorder in patients with epilepsy is less well studied, but there is evidence that the ASD risk is greater in those with epilepsy than in the general population. One of the risk factors is intellectual disability, and there is some evidence that the presence of a particular seizure

    Full Text Available Purpose: Triple negative breast cancer (TNBC is an aggressive subtype of breast cancer with poor prognosis despite the high rates of response to chemotherapy. We aim to study the clinical features, factors influencing recurrence and survival outcomes of TNBC patients.Methods: We retrospectively studied the charts of patients with biopsy proven TNBC treated at The Clinical Oncology Department Ain-Shams University between 2009 and 2012.Results: One hundred and forty five patients fulfilled the eligibility criteria. The incidence of TNBC was 10.5% - 15% with a mean of 12% of all breast cancer patients. The follow-up duration ranged from six months to four years. The age range was 26 to 78 years. Infiltrating ductal carcinoma represented 93.1% of the pathologic types. 87% of patients were free of metastases (M0 at presentation. Clinical stages II and III represented 38 and 39.5% of the patients. 66% of patients had modified radical mastectomy. Following surgery, 77.5% of patients received adjuvant chemotherapy while 61% of the patients had adjuvant radiation therapy. Anthracyclines based chemotherapy was given to 52% of patients. Disease-free survival (DFS of the M0 patients at 20 and 30 months was 92% and 80% respectively. Relapse occurred in 23% of M0 patients. After a mean duration of DFS of 15.1 months, the most common sites of metastases for relapsed M0 patients were pulmonary (44.8%, bone (41.4%, and locoregional (13.8%. The median overall survival (ORS of patients was 18 months (1 - 45 months, whereas for the M1 group of patients the median ORS was 9 months (2 - 29 months.Conclusion: The incidence, pathological characteristics, and clinical behavior of TNBC were similar to what is mentioned in the literature. Adding taxanes to the chemotherapy protocols and using postoperative radiotherapy were both associated with a significant increase in the mean period of DFS, while did not significantly affect the ORS.

    Comprehensive pain evaluation is requisite for optimal management. Few studies have evaluated pain syndromes and adequacy of associated analgesic regimens in one population. Available studies in cancer populations have focused on ambulatory patients or hospice-type inpatients. This study was designed to evaluate multiple characteristics of pain and adequacy of therapy in a broad spectrum of patients with advanced cancer presenting to a palliative medicine service. One hundred pain patients (95 with cancer) underwent a comprehensive pain evaluation consisting of history, physical examination, review of available diagnostics, and a pain assessment tool designed for routine clinical use. Seventy-one percent of 141 evaluable patients reported pain in the month before referral. In these 100 patients, 158 distinct sites of pain were reported, with 88 percent reporting a maximum of 2. Pain due to tumor was the most common cause (68 percent), and the most common pathophysiologic mechanism, somatic (52 percent). Pain was almost equally divided between continuous (48 percent) and intermittent (52 percent). Breakthrough pain occurred in 75 percent of continuous pains. Of these, 30 percent were exclusively incidental, 26percent nonincidental, and 16 percent due to end-of-dose failure. The remainder was of mixed etiology, but almost always with an incidental component. Of intermittent pain syndromes, 61 percent were incidental. On referral, analgesic dosing was inadequate and was compounded by use of regimens that typically did not meet peer-reviewed guidelines. Comprehensive studies rigorously evaluating characteristics of pain and response to treatment are a necessary first step toward more effective treatments for difficult pain syndromes.

    Although not regularly transfused, patients with non-transfusion-dependent thalassemia (NTDT) are prone to iron overload and its complications. Their molecular, phenotypical and laboratory characteristics vary in different populations and there is a need to document local prevailing patterns. We have reviewed the records of our patients with NTDT in Kuwait and documented their clinical and molecular characteristics in addition to iron status [serum ferritin and liver magnetic resonance imaging (MRI) T2*], management and complications. There were 41 patients, made up of 20 with β-thalassemia intermedia (β-TI), 18 with Hb H (β4) disease and three with Hb E (HBB: c.79G > A)-β-thalassemia (Hb E-β-thal); their ages ranged from 3 to 36 years (mean 12.5 ± 7.7). While 18 (43.9%) had been transfused at least once, only three (7.3%) had been transfused on multiple occasions. Three patients had serum ferritin >500 ng/mL; while four of 38 had mild or moderate liver iron overload. Seven (35.0%) of the β-TI patients were managed with hydroxyurea (HU) with good response. Other complications included five patients with gallstones and one each of hypothyroidism and moyamoya. The most common mutations among the β-TI patients were IVS-II-1 (G > A) and IVS-I-6 (T > C), while among the Hb H patients, the Saudi α2-globin gene polyadenylation (polyA) (AATAAA > AATAAG) mutation was responsible for all cases either as homozygotes (61.1%) or compound heterozygotes with the α-thal-2 (-α(3.7)) allele (33.3%). Although the pattern of NTDT in Kuwaiti patients is generally mild, there is a need to follow them to adulthood as the complications are cumulative and more prevalent in this group.

    In general, melanoma can be considered as a UV-driven disease with an aggressive metastatic course and high mutational load, with only few tumors (acral, mucosal, and uveal melanomas) not induced by sunlight and possessing a lower mutational load. The most commonly activated pathway in melanoma is the mitogen-activated protein kinase (MAPK) pathway. However, the prognostic significance of mutational stratification is unclear and needs further investigation. Here, in silico we combined mutation data from 162 melanomas subjected to targeted deep sequencing with mutation data from three published studies. Tumors from 870 patients were grouped according to BRAF, RAS, NF1 mutation or triple-wild-type status and correlated with tumor and patient characteristics. We found that the NF1-mutated subtype had a higher mutational burden and strongest UV mutation signature. Searching for co-occurring mutated genes revealed the RASopathy genes PTPN11 and RASA2, as well as another RAS domain-containing gene RASSF2 enriched in the NF1 subtype after adjustment for mutational burden. We found that a larger proportion of the NF1-mutant tumors were from males and with older age at diagnosis. Importantly, we found an increased risk of death from melanoma (disease-specific survival, DSS; HR, 1.9; 95% CI, 1.21-3.10; P = 0.046) and poor overall survival (OS; HR, 2.0; 95% CI, 1.28-2.98; P = 0.01) in the NF1 subtype, which remained significant after adjustment for age, gender, and lesion type (DSS P = 0.03, OS P = 0.06, respectively). Melanoma genomic subtypes display different biological and clinical characteristics. The poor outcome observed in the NF1 subtype highlights the need for improved characterization of this group.

    Full Text Available Background and objective Pulmonary sarcomatoid carcinoma is a rare histologic subtype of non-small cell lung cancer. The effective treatment for this disease has not well defined due to its extremely low morbidity. This study explores the clinicopathological characteristics and prognosis of 38 patients with PSC, so as to provide some clues for its diagnosis and treatment. Methods The study enrolled 38 patients with PSC that were diagnosed with histology or cytology in our hospital between January 2000 and December 2013. We retrospectively analyzed general clinical characteristics, smoking history, tumor size, TNM staging, pathology, immunohistochemistry, diagnostic method, treatment and prognosis. We used SPSS 19.0 statistical software and Kaplan-Meier method to analyze our data. Results Patients in this study were aged from 26 to 76 years old (the median age was 57.5 years old. Among all of them, the male to female ratio was 4:1, and 81.6% of patients had smoking history. Cough and hemoptysis were the most common primary symptoms. The median survival was 21 months, while one-year survival rate, three-year survival rate and five-year survival rate were 68.4%, 31.6% and 18.4% respectively. Tumor size, TNM staging, distant metastasis and surgery therapy were associated with the prognosis of patients. Conclusion Patients with PSC present with no special symptoms generally. According to our study, factors that affect patients’ prognosis include tumor size, TNM staging, distant metastasis and surgery. Complete resection is the key treatment for PSC patients, but comprehensive chemoradiotherapy needs further exploration in evidence-based medicine. Biological target therapy may give new insight into treatment for PSC.

    Full Text Available OBJECTIVES: Cytotoxic agents and steroids are used to treat lymphoid malignancies, but these compounds may exacerbate chronic viral hepatitis. For patients with multiple myeloma, the impact of preexisting hepatitis virus infection is unclear. The aim of this study is to explore the characteristics and outcomes of myeloma patients with chronic hepatitis virus infection. METHODS: From 2003 to 2008, 155 myeloma patients were examined to determine their chronic hepatitis virus infection statuses using serologic tests for the hepatitis B (HBV and C viruses (HCV. Clinical parameters and outcome variables were retrieved via a medical chart review. RESULTS: The estimated prevalences of chronic HBV and HCV infections were 11.0% (n = 17 and 9.0% (n = 14, respectively. The characteristics of patients who were hepatitis virus carriers and those who were not were similar. However, carrier patients had a higher prevalence of conventional cytogenetic abnormalities (64.3% vs. 25.0%. The cumulative incidences of grade 3-4 elevation of the level of alanine transaminase, 30.0% vs. 12.0%, and hyperbilirubinemia, 20.0% vs. 1.6%, were higher in carriers as well. In a Kaplan-Meier analysis, carrier patients had worse overall survival (median: 16.0 vs. 42.4 months. The prognostic value of carrier status was not statistically significant in the multivariate analysis, but an age of more than 65 years old, the presence of cytogenetic abnormalities, a beta-2-microglobulin level of more than 3.5 mg/L, and a serum creatinine level of more than 2 mg/ dL were independent factors associated with poor prognosis. CONCLUSION: Myeloma patients with chronic hepatitis virus infections might be a distinct subgroup, and close monitoring of hepatic adverse events should be mandatory.

    Full Text Available Abstract Background Guidelines recommend multifactorial intervention programmes to prevent falls in older adults but there are few randomised controlled trials in a real life health care setting. We describe the rationale, intervention, study design, recruitment strategies and baseline characteristics of participants in a randomised controlled trial of a multifactorial falls prevention programme in primary health care. Methods Participants are patients from 19 primary care practices in Hutt Valley, New Zealand aged 75 years and over who have fallen in the past year and live independently. Two recruitment strategies were used – waiting room screening and practice mail-out. Intervention participants receive a community based nurse assessment of falls and fracture risk factors, home hazards, referral to appropriate community interventions, and strength and balance exercise programme. Control participants receive usual care and social visits. Outcome measures include number of falls and injuries over 12 months, balance, strength, falls efficacy, activities of daily living, quality of life, and physical activity levels. Results 312 participants were recruited (69% women. Of those who had fallen, 58% of people screened in the practice waiting rooms and 40% when screened by practice letter were willing to participate. Characteristics of participants recruited using the two methods are similar (p > 0.05. Mean age of all participants was 81 years (SD 5. On average participants have 7 medical conditions, take 5.5 medications (29% on psychotropics with a median of 2 falls (interquartile range 1, 3 in the previous year. Conclusion The two recruitment strategies and the community based intervention delivery were feasible and successful, identifying a high risk group with multiple falls. Recruitment in the waiting room gave higher response rates but was less efficient than practice mail-out. Testing the effectiveness of an evidence based intervention in a

    Full Text Available Rotavirus (RV infection in neonatal age can be mild or even asymptomatic. Several studies have reported that RV is responsible for 31%-87% of pediatric nosocomial diarrhea and causes gastroenteritis outbreaks in pediatric and neonatal units.Study clinical characteristics, genotypes and risk factors of RV infection in neonatal age.A prospective study was conducted from April 2009 till April 2013 in the neonatal special care unit of the largest tertiary pediatric hospital of Greece. Fecal samples and epidemiological data were collected from each neonate with gastrointestinal symptoms. RV antigen was detected with a rapid immunochromatography test. RV positive samples were further genotyped with RT PCR and sequencing using specific VP7 and VP4 primers.Positive for RV were 126/415 samples (30.4%. Mean age of onset was 18 days. Seventy four cases (58% were hospital acquired. Seasonality of RV infection did not differ significantly throughout the year with the exception of 4 outbreaks. Genotypes found during the study period were G4P[8] (58.7%, G1P[8] (14.7%, G12P[8] (9.3%, G3P[8] (9.3%, G12P[6] (5.3%, G9P[8] (1.3% and G2P[4] (1.3%. RV cases presented with: diarrhea (81%, vomiting (26.2%, fever (34.9%, dehydration (28.6%, feeding intolerance (39.7%, weight loss (54%, whilst 19% of cases were asymptomatic. Comparing community with hospital acquired cases differences in clinical manifestations were found.Significant incidence of nosocomially transmitted RV infection in neonatal age including asymptomatic illness exists. Genotypes causing nosocomial outbreaks are not different from community strains. Circulating vaccines can be effective in prevention of nosocomial RV infection through herd immunity.

    Full Text Available ABSTRACT Objectives: Innate immunity is involved in the physiopathology of ankylosing spondylitis (AS, with the participation of Gram-negative bacteria, modulation of human leukocyte antigen (HLA B27 and the involvement of pattern recognition receptors, such as Toll-like receptors (TLRs. The aim of this study was to investigate the clinical characteristics and frequency of TLR4 polymorphisms (Asp299Gly and Thr 399Ile in a cohort of Brazilian patients with AS. Methods: A cross-sectional study was carried out involving 200 patients with a diagnosis of AS and a healthy control group of 200 individuals. Disease activity, severity and functional capacity were measured. The study of TLR4 polymorphisms was performed using the restriction fragment length polymorphism method. HLA-B27 was analyzed by conventional polymerase chain reaction. The IBM SPSS Statistics 20 program was used for the statistical analysis, with p-values less than 0.05 considered significant. Results: Mean age and disease duration were 43.1 ± 12.7 and 16.6 ± 9.2 years, respectively. The sample was predominantly male (71% and non-Caucasian (52%. A total of 66% of the group of patients were positive for HLA-B27. The sample of patients was characterized by moderate functional impairment and a high degree of disease activity. No significant association was found between the two TLR4 polymorphisms and susceptibility to AS. Conclusions: TLR4 polymorphisms 399 and 299 were not more frequent in patients with AS in comparison to the health controls and none of the clinical variables were associated with these polymorphisms.

    Full Text Available Background: Acute Lower Respiratory Tract Infection (ALRTI is the leading cause of deaths in children under 5 years of age worldwide, and has high morbidity and mortality in children with Congenital Heart Disease (CHD. The objective of this study was to obtain the incidence, clinical characteristic, and outcome of ALRTI children with CHD. Methods: A retrospective hospital-based study was conducted from January 2007–December 2011 to medical record of child patients with ALRTI and CHD in the Department of Child Health of Dr. Hasan Sadikin General Hospital, Bandung. The diagnosis of CHD was determined by echocardiography. The collected data was analyzed and presented in percentage shown in tables. Results : From 3,897 children who had ALRTI, there were 149 children with CHD (3.8%, with 11.4% of whom founded with recurrent episodes. This happened often in girls than boys with quite similar ratio of 1.37: 1.The majority of children (80% was under 1 year old of age, 72.5% with malnutrition, and 24.8% with severe malnutrition. Clinical symptoms mostly found were difficulty of breathing (98%, fever (85.2%, cough (75.2%, and runny nose (63.1%. The most common types of CHD were Patent Ductus Arteriosus (47.6%, followed by Ventricular Septal Defect (47%. Bronchopneumonia (86.6% was the common type of ALRTI. The length of stay was mostly less than 10 days (70.5%. From all the children 43.7% had complications, and 6.7% died. Conclusions: The ALRTI in children with CHD is not common and has good outcome. The majority for CHD lesions are Patent Ductus Arteriosus and Ventricular Septal Defect while for ALRTI is Bronchopneumonia.

    Background: Polycystic ovary syndrome (PCOS) is a common disorder. PCOS women are at a high risk for insulin resistance and metabolic syndrome (MS). Adiponectin is positively related to insulin sensitivity. It has a preventive role in atherogenesis and MS. The present work was conducted to study the correlation between serum adiponectin levels and clinical characteristics and biochemical parameters in PCOS patients. Materials and Methods: A prospective study in 49 newly diagnosed (as per Rotterdam criteria) Indian PCOS women was conducted. PCOS women were clinically examined and investigated for biochemical parameters. Results: The mean serum adiponectin was 12 ± 9.4 μg/mL (range 0.47-45). Hypoadiponectinemia (serum adiponectin <4 μg/mL) was present in 22% patients. Age and adiponectin correlated significantly and inversely (r = −0.42, P = 0.027). Overweight/obese patients had lower mean adiponectin levels than normal weight (11.62 ± 9.5 vs 13.58 ± 9.5, P = 0.56). It was significantly lower in patients with acanthosis nigricans (AN) as compared with those without AN (8.4 ± 5.9 vs 15 ± 11, P = 0.038). Hirsute patients showed lower mean adiponectin levels than nonhirsute (10 ± 7.3 vs 13 ± 10, P = 0.57). A positive, insignificant correlation was observed between serum adiponectin and cholesterol, low-density lipoprotein, follicle stimulating hormone (FSH), thyroid stimulating hormone, levels. A negative insignificant correlation existed between serum adiponectin and luteinizing hormone (LH), LH: FSH ratio, prolactin, dehydroepiandrosterone, testosterone, triglyceride, high-density lipoprotein, fasting blood glucose, fasting insulin, and Homeostasis Model Assessment. Conclusion: Hypoadiponectinemia is present in one-fifth of women with PCOS. Adiponectin levels decrease as age advances. Low levels of adiponectin possibly contributes to the development of dermal manifestation (AN) of insulin resistance. PMID:24741521

    Background Although many factors are involved in the etiology of xanthelasma palpebrum, lipid disorder is strongly associated with its induction. Xanthelasma palpebrum, the most common type of xanthoma, usually presents in middle-aged females and results in aesthetic problems. Objective To evaluate thelipid profile and important clinical aspects of xanthelasma palpebrum patients. Methods In this descriptive study, we enrolled 42xanthelasma palpebrumpatients, and 42 cases of non-inflammatory skin disorders as thecontrol group, matched for age and gender.The clinical characteristics of the patients and fasting serum lipid profile were recorded for both groups. The data obtained were analyzed using SPSS-16. Results Xanthelasma palpebrum was found more commonly in middle-aged females with disease onset of less than 1 year, and without significant familial history of xanthoma. Furthermore,xanthelasma lesionswere most often seen in the upper lid with mild extension and was rarely associated with systemic disease. There was no statistically significant difference between two groups regarding hypertriglyceridemia (p= 0.231) and hypercholesterolemia (p= 0.302). The mean serum levels of cholesterol (221.51±60.4 mg/dl), triglyceride (185.98±71.1 mg/dl) and VLDL (37.7±17.6 mg/dl) were significantly higher and themedian HDL (36.2 (31, 41) mg/dl) level was lower in thepatient group. Conclusion In our study, hypercholesterolemia and hypertriglyceridemia did not reveal a significant difference between thepatient and control groups; however, mean serum values for cholesterol, triglyceride, VLDL and HDL showed a significant difference between the two groups. Therefore, in addition to lipid abnormality, other factors could be involved in the pathogenesis of xanthelasma palpebrum. PMID:27579742

    Full Text Available Periodic monitoring of Staphylococcus aureus characteristics in a locality is imperative as their drug-resistant variants cause treatment problem. In this study, antibiograms, prevalence of toxin genes (sea-see, seg-ser, seu, tsst-1, eta, etb, and etd, PFGE types, accessory gene regulator (agr groups, and ability to form biofilm of 92 S. aureus Thailand clinical isolates were investigated. They were classified into 10 drug groups: groups 1–7 (56 isolates were methicillin resistant (MRSA and 8–10 (36 isolates were methicillin sensitive (MSSA. One isolate did not have any toxin gene, 4 isolates carried one toxin gene (seq, and 87 isolates had two or more toxin genes. No isolate had see, etb, or tsst-1; six isolates had eta or etd. Combined seg-sei-sem-sen-seo of the highly prevalent egc locus was 26.1%. The seb, sec, sel, seu, and eta associated significantly with MSSA; sek was more in MRSA. The sek-seq association was 52.17% while combined sed-sej was not found. Twenty-three PFGE types were revealed, no association of toxin genes with PFGE types. All four agr groups were present; agr group 1 was predominant (58.70% but agr group 2 strains carried more toxin genes and were more frequent toxin producers. Biofilm formation was found in 72.83% of the isolates but there was no association with antibiograms. This study provides insight information on molecular and phenotypic markers of Thailand S. aureus clinical isolates which should be useful for future active surveillance that aimed to control a spread of existing antimicrobial resistant bacteria and early recognition of a newly emerged variant.

    Renal cancer is rare and its incidence is 1.9 per 100,000 in the Malaysian population, which consists of three major ethnic groups (Malay, Chinese and Indians). A retrospective study was her conducted to identify clinical characteristics and ethnic background influences on presentation. The study included all renal cancer patients from a single medical institution over ten years, with a total of 75 cases. Seventy-three patients underwent surgery while 2 received only radiotherapy or chemotherapy. The male to female ratio was 2.75:1. Incidence was equal among the Malay (49.3%) and Chinese ethnic groups (45.3%). Mean age of patients were 57.1 (18-93) years old. There were 26 (37.4%) patients with Stage I disease, 14 (18.7%) at Stage II, 23 (30.7%) at Stage III and 12 (16%) at Stage IV. The Chinese race presented at mean older age (p= 0.02) and later stage of disease (p= 0.046). Patients above 40 years old had more advanced stage disease (p= 0.023). Tumour histology were clear cell (72%), urothelial cell (13.3%), sarcomatoid cell and nephroblastoma each contributed 2.7%. The mean tumour size was 8.1 (2-20) cm. There was substantial agreement between the pre and post operative staging (kappa 0.691). In conclusion we observed significant influences of age and race in the clinical presentation of renal cancer in our institution based population. There was larger male to female ratio and mean tumour size as compared to previous epidemiology studies.

    Invasive infections due to carbapenem-resistant Enterobacteriaceae (CRE), including polymyxin-resistant (PR-CRE) strains, are being increasingly reported. However, there is a lack of clinical data for several life-threatening infections. Here we describe a cohort of patients with post-surgical mediastinitis due to CRE, including PR-CRE. This study was a retrospective cohort design at a single cardiology centre. Patients with mediastinitis due to CRE were identified and were investigated for clinically relevant variables. Infecting isolates were studied using molecular techniques. Patients infected with polymyxin-susceptible CRE (PS-CRE) strains were compared with those infected with PR-CRE strains. In total, 33 patients with CRE mediastinitis were studied, including 15 patients (45%) with PR-CRE. The majority (61%) were previously colonised. All infecting isolates carried blaKPC genes. Baseline characteristics of patients with PR-CRE mediastinitis were comparable with those with PS-CRE mediastinitis. Of the patients studied, 70% received at least one agent considered active in vitro and most patients received at least three concomitant antibiotics. Carbapenem plus polymyxin B was the most common antibiotic combination (73%). Over 90% of patients underwent surgical debridement. Overall, in-hospital mortality was 33% and tended to be higher in patients infected with PR-CRE (17% vs. 53%; P=0.06). In conclusion, mediastinitis due to CRE, including PR-CRE, can become a significant challenge in centres with CRE and a high cardiac surgery volume. Despite complex antibiotic treatments and aggressive surgical procedures, these patients have a high mortality, particularly those infected with PR-CRE.

    2014-01-01

    The high sensitivity of PCR assays for diagnosing Clostridium difficile infection (CDI) has greatly reduced the need for repeat testing after a negative result. Nevertheless, a small subset of patients do test positive within 7 days of a negative test. The aim of this study was to evaluate the clinical characteristics of these patients to determine when repeat testing may be appropriate. The results of all Xpert C. difficile PCR (Cepheid, Sunnyvale CA) tests performed in the clinical microbiology laboratory at New York-Presbyterian Hospital, Columbia University Medical Center (NYPH/CUMC) from 1 May 2011 through 6 September 2013, were reviewed. A retrospective case-control study was performed, comparing patients who tested positive within 7 days of a negative test result to a random selection of 50 controls who tested negative within 7 days of a negative test result. During the study period, a total of 14,875 tests were performed, of which 1,066 were repeat tests (7.2%). Eleven of these repeat tests results were positive (1.0%). The only risk factor independently associated with repeat testing positive was history of a prior CDI (odds ratio [OR], 19.6 [95% confidence interval {CI}, 4.0 to 19.5], P < 0.001). We found that patients who test positive for C. difficile by PCR within 7 days of a negative test are more likely to have a history of CDI than are patients who test negative with repeat PCR. This finding may be due to the high rate of disease relapse or the increased likelihood of empirical therapy leading to false-negative results in these patients. PMID:25122866

    Cervical radiculopathy of the C2-4 spinal nerves is a rare condition and is poorly documented in terms of clinical symptoms, hindering its detection during initial patient screening based on imaging diagnostics. The authors describe in detail the clinical symptoms and successful surgical treatment of a patient diagnosed with isolated C-4 radiculopathy. This 41-year-old man suffered from sleep disturbance because of pain behind the right ear, along the right clavicle, and at the back of his neck on the right side. The Jackson and Spurling tests were positive, with pain radiating to the area behind the patient's ear. Unlike in cases of radiculopathy involving the C5-8 spinal nerves, no loss of upper-extremity motor function was seen. Magnetic resonance imaging showed foraminal stenosis at the C3-4 level on the right side, and multiplanar reconstruction CT revealed a beak-type ossification of the posterior longitudinal ligament in the foraminal region at the same level. In the absence of intracranial lesions or spinal cord compressive lesions, the positive Jackson and Spurling tests and the C3-4 foraminal stenosis were indicative of isolated C-4 radiculopathy. Microscopic foraminotomy was performed at the C3-4 vertebral level and the ossified lesion was resected. The patient's symptoms completely resolved immediately after surgery. To the authors' knowledge, this report is the first to describe the symptomatic features of isolated C-4 radiculopathy, in a case in which the diagnosis has been confirmed by both radiological findings and surgical outcome. Based on this case study, the authors conclude that the characteristic symptoms of C-4 radiculopathy are the presence of pain behind the ear and in the clavicular region in the absence of upper-limb involvement.

We present the occipital neuralgia series from the specialised headache unit at a tertiary hospital and analyse its clinical characteristics and its response to therapy. PATIENTS AND METHODS. Variables were collected from the cases of occipital neuralgia diagnosed in the above-mentioned headache unit between January 2008 and April 2013. RESULTS. A series of 14 patients (10 females, 4 males) with occipital neuralgia was obtained out of a total of 2338 (0.59%). Age at onset of the clinical signs and symptoms: 53.4 ± 20.3 years (range: 17-81 years) and time elapsed to diagnosis was 35.5 ± 58.8 months (range: 1-230 months). An intracranial or cervical pathology was ruled out by suitable means in each case. Baseline pain of a generally oppressive nature and an intensity of 5.3 ± 1.3 (4-8) on the verbal analogue scale was observed in 13 of them (92.8%). Eleven (78.5%) presented exacerbations, generally stabbing pains, a variable frequency (4.6 ± 7 a day) and an intensity of 7.8 ± 1.7 (range: 4-10) on the verbal analogue scale. Anaesthetic blockade was not performed in four of them (two due to a remitting pattern and two following the patient's wishes); in the others, blockade was carried out and was completely effective for between two and seven months. Four cases had previously received preventive treatment (amitriptyline in three and gabapentin in one), with no response. CONCLUSIONS. In this series from a specialised headache unit, occipital neuralgia is an infrequent condition that mainly affects patients over 50 years of age. Given its poor response to preventive treatment, the full prolonged response to anaesthetic blockades must be taken into account.

    Despite the established association between chronic idiopathic/spontaneous urticaria (CIU) and presence of antinuclear antibodies (ANAs), the prevalence of autoimmune comorbidities in this population has not been analyzed. Here, we aim to identify clinical and laboratory manifestations associated with ANA-positive CIU. ANA-positive patients were identified via electronic data capture from the electronic patient record database of Leumit Health care Services (LHS) of Israel. Patient characteristics, medical histories, and details of diagnostic workup, medical treatment, and follow-up were retrieved by performing a chart review of electronic patient records (EPRs). The prevalence of target diseases among ANA(+) CIU(+), ANA(+) CIU(-), and ANA(-) CIU(+) patients was calculated. A total of 91 ANA(+) CIU(+), 3131 ANA(+) CIU(-), and 478 ANA(-) CIU(+) patients were identified. The ANA(+) CIU(+) group was characterized by higher prevalence of Sjögren's syndrome (SS)-A 52 antibodies (Ab) (7.7% versus 2.4%; p = 0.008), SS-A 60 Ab (11% versus 2.8%; p = ANA(-) CIU(+) group. Additionally, ANA(+) CIU(+) patients were more likely to be diagnosed with thyroid autoimmune diseases, higher C-reactive protein (6.4 ± 10.3 versus 4.1 ± 8.8 mg/L; p = 0.027), and more profound basopenia (0.04 ± 0.09 versus 0.15 ± 0.11 cell/mm(3); p ANA(-) CIU patients. More ANA(+) CIU(+) patients were resistant to four-fold standard licensed doses of antihistamines than ANA(-) CIU(+) patients [11 (12.1%) versus 29 (6.1%); p = 0.046]. ANA-positive CIU is characterized by higher prevalence of SS-A 52, SS-A 60, and SS-B antibodies and poorer clinical response to antihistamine medications.

    Objective To study the clinical characteristics of 2952 patients with epilepsy who had received drug treatment from the neurology outpatient clinics of eight major hospitals in Hong Kong. Methods Retrospective review of outpatient records. Results 1601 (54.3%) males and 1351 (45.7%) females with a median age of 35.8 years (range, 10-94.8) were studied. Seizure types included generalized tonic-clonic in 80.7% of patients, complex partial in 28.3%, simple partial in 14.4%, atypical absence in 2.6% and myoclonic in 1.4%, and 30.4% of patients had more than one seizure type. EEG, CT brain, MRI brain and neuropsychological evaluation were obtained in 81.2%, 61.7%, 17.0% and 2.2% of patients, respectively. The etiology of epilepsy was cryptogenic in 59.9%, symptomatic in 35.1% and idiopathic in 3.9%; the commonest were intracranial infection, cerebral vascular disease, cranial trauma and perinatal insult. Phenytoin, carbamazepine and valproate were the most frequently used drugs and 25.9% of patients were taking more than two drugs. 48.3% of patients had active seizures in the past six months and 26.4% were considered to have unsatisfactory control of their epilepsy. Medical refractoriness of epilepsy was associated with a history of perinatal insult, intracranial infection, congenital brain malformation, intracranial neoplasm, cerebral vascular disease, hippocampal sclerosis, mental retardation and a history of status epilepticus (P<0.05). Conclusion In this local cohort of adult patients with epilepsy under specialist care, there were a considerable number of patients falling into the category of cryptogenic epilepsy. Risk factors associated with medical refractoriness are similar to previous studies.

    Objective To observe the clinical manifestations and assess direct antiviral effect for patients with occult hepatitis B in China. Methods The study includes 15 patients with occult hepatitis B and their medical history, family history, ifrst-diagnosis time, conifrmed-diagnosis time, laboratory report, anti-viral therapy and outcomes were analyzed. Results The average age of the patients is 38.67-year old (6 males and 9 females), 2 with acute hepatitis B (2/15, 13.3%), 13 with no hepatitis history (13/15, 86.6%), 8 with family history (8/15, 53.3%), 6 with no family history (6/15, 40%), 1 with unknown family history (1/15, 6.6%). Eight patients were treated with entecavir (0.5 mg/day, taken orally), with effective results and steady conditions;3 patients were treated with lamivudine (0.1 g/day, taken orally), 2 of them were prescribed to take adefovir dipivoxil additionally due to drug-resistance, the other one was treated with lamivudine continuously without drug-resistance;4 cases refused anti-viral therapy. One patient’s condition remained steady, 1 patient died of cirrhosis with portal hypertension and liver failure 5 years after ifrst-diagnosis, 1 patient progressed to hepatocellular carcinoma and accepted surgery operation treatment 5 years after ifrst-diagnosis, the other 1 patient progressed to compensatory cirrhosis 2 years after ifrst-diagnosis and is steady from then, which indicates that occult chronic hepatitis B can progress to cirrhosis and hepatocellular carcinoma without therapy in time. Conclusions The clinical characteristics of 15 cases with occult chronic hepatitis B showed that these patients with short latency, younger age when being-struck, and light damage to liver function. The efifcacy and drug-resistance of nucleos(t)ide-analogue (entecavir, lamivudine, adefovir dipivoxil) in treatment of patients with occult chronic hepatitis B are similar to chronic hepatitis B.

    The high sensitivity of PCR assays for diagnosing Clostridium difficile infection (CDI) has greatly reduced the need for repeat testing after a negative result. Nevertheless, a small subset of patients do test positive within 7 days of a negative test. The aim of this study was to evaluate the clinical characteristics of these patients to determine when repeat testing may be appropriate. The results of all Xpert C. difficile PCR (Cepheid, Sunnyvale CA) tests performed in the clinical microbiology laboratory at New York-Presbyterian Hospital, Columbia University Medical Center (NYPH/CUMC) from 1 May 2011 through 6 September 2013, were reviewed. A retrospective case-control study was performed, comparing patients who tested positive within 7 days of a negative test result to a random selection of 50 controls who tested negative within 7 days of a negative test result. During the study period, a total of 14,875 tests were performed, of which 1,066 were repeat tests (7.2%). Eleven of these repeat tests results were positive (1.0%). The only risk factor independently associated with repeat testing positive was history of a prior CDI (odds ratio [OR], 19.6 [95% confidence interval {CI}, 4.0 to 19.5], P PCR within 7 days of a negative test are more likely to have a history of CDI than are patients who test negative with repeat PCR. This finding may be due to the high rate of disease relapse or the increased likelihood of empirical therapy leading to false-negative results in these patients.

    Summary: In order to assess the clinical manifestations and electrocardiogram (ECG) characteristics of Chinese long QT syndrome (LQTS) patients and describe the phenotype-genotype correlation,the subjects from 5 congenital LQTS families underwent clinical detailed examination including resting body surface ECG. QT interval and transmural dispersion of repolarization (TDR) were manually measured. Five families were genotyped by linkage analysis (polymerase chain reacting-short tandem repeat, PCR-STR). The phenotype-genotype correlation was analyzed. Four families were LQT2, 1 family was LQT3. Twenty-eight gene carriers were (14 males and 14 females) identified from 5 families. The mean QTc and TDRc were 0. 56±0. 04 s (range 0.42 to 0.63) and 0.16±0.04 s (range 0. 09 to 0. 24) respectively. 35. 7 % (10/28) had normal to borderline QTc (≤0. 460 s). There was significant difference in QTc and TDRc between the patients with symptomatic LQTS and those with asymptomatic LQTS, and there was significant difference in TDRc between the asymptomatic patients and normal people also. A history of cardiac events was present in 50 %(14/28), including 9 with syncope, 2 with sudden death (SD) and occurred in the absence of β-blocker. Three SDs occurred prior to the diagnosis of LQTS and had no ECG record. Two out of 5 SDs (40 %) occurred as the first symptom. Typical LQT2 T wave pattern were found in 40 % (6/15) of all affected members. The appearing-normal T wave was found in one LQT3 family. Low penetrance of QTc and symptoms resulted in diagnostic challenge. ECG patterns and repolarization parameters may be used to predict the genotype in most families. Genetic test is very important for identification of gene carriers.

    Full Text Available Assaultive acts committed by people with a mental illness is a major public health issue that affects patients with their families, law enforcement authorities, and the public at large. Failure to provide treatment is in fact a major predictor of assaultive acts in patients with schizophrenia living in the community. Considering that the indigenous ethnic groups of Central Asia have similar sociocultural characteristics, these factors may be reflected in individuals with schizophrenia who have committed serious assaultive acts in Uzbekistan.Objectives: The aim of the work was to identify the sociocultural and clinical characteristics of schizophrenic representatives of indigenous ethnic groups of Central Asia who have committed violent crimes in Uzbekistan and have been found insane in regard to their offence, and to compare these subjects to ones belonging to the other ethnic groups.Material and methods: The data were collected in 2010–2013 in the Tashkent High Security Psychiatric Hospital via face-to-face interviews and also from the patients’ charts and from forensic psychiatric examination statements.Results: The sample consisted of 201 individuals. The sample was 90.1 percent (n = 181 male, with a predominance of the paranoid schizophrenia subtype according to the ICD-10 criteria. Of the subjects, 174 ones (86.6% were representatives of the indigenous ethnic groups of Central Asia, and 27 ones (13.4% were representatives of other ethnic groups. The duration of illness among the subjects belonging to the indigenous ethnic groups of Central Asia was less than in the other group; the individuals were rarely referred to psychiatric care because of the popularity of alternative medicine and the stigma attached to mental illness. A positive correlation between violence and various psychotic symptoms, such as delusions, hallucinations, and thought disorder, has also been demonstrated in this group.Conclusions: Sociocultural characteristics

    Cytotoxic chemotherapy suppresses the haematopoietic system, febrile neutropenia is the most serious haematological toxicity associated with the risk of life-threatening infections. We present a retrospective study of 200 episodes of febrile neutropenia in 128 patients treated in department of medical oncology. The aim of this study was to determinate the clinical, therapeutic and evolutive characteristics in patients treated essentially for solid tumors. Among these patients, 72% of them have at least two episodes, the median age was 34 years with extremes six and 75 years. It has been noticed that 26.3% of patients have diabetes, the dominate neoplasm was solid tumors in 79.7%, 65% of patients have received preventive colony-stimulating factors, 83% have received preventive buccal disinfection with antifungic. The median duration of hospitalisation was 12 days, the median delay of febrile neutropenia was 10 days with extremes two and 31 days, median duration of febrile neutropenia was 5.45 days with extremes one and 24 days. Among these cases, 9.45% of them have nadir zero, 68% of patients have clinical documented infections, ORL in 47% of cases. According to the study, 12% of cases have documented microbiological fever, the sites was urinary in 33% of cases, blood in 33% of cases, derm in 30% of cases. The microbe was staphylococcus negative coagulase in 37.5% essentially in blood and derm, the Escherichia coli in 20.8% essentially in urinary and blood. First line antibiotherapy was cefotaxim associated with amikacine in 93.5%, second line antibiotherapy was association of imipenam and amikacine in 82% of cases. Among these cases,7% of them have received anti-staphylococcus, and antifungic treatment in 50% of cases. The thermic defervescence was obtained in median delay of 2.8 days.

    Full Text Available Background/Aim. Acute non-A, non-B, non-C, non-D, non-E hepatitis (non-A-E AH is an acute disease of the liver of unknown etiology for which one or more new, so far undetected, hepatotropic viruses may be responsible. The frequency of non-A-E AH ranges from 3.8% to 33.9%, and therefore it has a significant place within current infectology and hepatology. The aim of our study was to establish the frequency, clinical and biochemical characteristics, natural course and outcome of non-A-E AH and compare them with control groups affected by acute viral hepatitis A, B and C. Methods. This descriptive-analytic prospective study included 31 patients with non-A-E AH treated at the Institute of Infectious and Tropical Diseases, Clinical Center of Serbia, Belgrade, from 2003 to 2008. They were followed up during the period not less than 6 months. The controls involved randomly selected patients, treated at the same time with a definite diagnosis of acute viral hepatitis A, B and C. Statistical data analysis used Mann-Whitney Utest, Student's t-test and variance analysis. The value of p < 0.05 was considered statistically significant. Results. The frequency of non-A-E AH was 7.6%. Almost no difference was found between sexes (male/female ratio was 1 : 1.07; it was developed in all age groups, with the highest incidence in the middle age (mean age was 38.32 ± 15.3 years. It appeared equally throughout the whole year. Out of risk factors, inoculation risk was predominant (before all, dental interventions, mostly involving urban population living in comfortable conditions. The duration of incubation varied much ranging from 20 to 180 days (median 60 days. By clinical course, moderate and icteric forms were most common, mostly corresponding to acute hepatitis A and C. On the other hand, by duration of the disease (mean duration was 67.1 ± 27.1 and chronic transformation, non-A-E AH resembled to acute hepatitis B. Progression to chronicity was recorded in 9

    Full Text Available Abstract Background We have previously reported activating mutations of the gene coding for the fibroblast growth factor receptor 3 (FGFR3 in invasive cervical carcinoma. To further analyze the role of FGFR3 in cervical tumor progression, we extended our study to screen a total of 75 invasive tumors and 80 cervical intraepithelial neoplasias (40 low-grade and 40 high-grade lesions. Results Using single strand conformation polymorphism (SSCP followed by DNA sequencing, we found FGFR3 mutation (S249C in all cases in 5% of invasive cervical carcinomas and no mutation in intraepithelial lesions. These results suggest that, unlike in bladder carcinoma, FGFR3 mutation does not or rarely occur in non invasive lesions. Compared to patients with wildtype FGFR3 tumor, patients with S249C FGFR3 mutated tumors were older (mean age 64 vs. 49.4 years, P = 0.02, and were more likely to be associated with a non-16/18 HPV type in their tumor. Gene expression analysis demonstrated that FGFR3 mutated tumors were associated with higher FGFR3b mRNA expression levels compared to wildtype FGFR3 tumors. Supervised analysis of Affymetrix expression data identified a significant number of genes specifically differentially expressed in tumors with respect to FGFR3 mutation status. Conclusion This study suggest that tumors with FGFR3 mutation appear to have distinctive clinical and biological characteristics that may help in defining a population of patients for FGFR3 mutation screening.

    Tuberculosis (TB) is a public health problem in many large cities. We retrospectively studied the clinical characteristics and treatment outcomes of patients with active TB at 6 hospitals in Bangkok and Nonthaburi, Thailand during 2008-2009. Eight hundred thirteen patients were included in the study. The mean age of subjects +/- SD was 41 +/- 14 years and mean body weight +/- SD was 53 +/- 11 kilograms. The three leading co-morbid conditions were HIV infection (40%), diabetes (6%) and chronic liver disease (2%). Two-thirds of subjects had isolated pulmonary TB. Isoniazid, rifampicin and multi-drug resistance were seen in 13, 7 and 5%, respectively. After 1 year, 52% were cured or completed treatment, 19% transferred out, 12% defaulted, 9% were still on-going TB treatment, 7% had died and 1% had failed treatment. Survival rates at 2, 6 and 12 months were 93, 85 and 81% among HIV seropositive subjects; 96, 94 and 92% among HIV seronegative subjects and 98, 97 and 97% among subjects with unknown HIV status (p Bangkok, Thailand.

    Objectives: To determine the clinical features and the distribution of diagnosis in partially sighted school-age children, to report the chosen low vision rehabilitation methods and to emphasize the importance of low vision rehabilitation. Materials and Methods: The study included 150 partially sighted children between the ages of 6 and 18 years. The distribution of diagnosis, accompanying ocular findings, visual acuity of the children both for near and distance with and without low vision devices, and the methods of low vision rehabilitation (for distance and for near) were determined. The demographic characteristics of the children and the parental consanguinity were recorded. Results: The mean age of children was 10.6 years and the median age was 10 years; 88 (58.7%) of them were male and 62 (41.3%) of them were female. According to distribution of diagnoses among the children, the most frequent diagnosis was hereditary fundus dystrophies (36%) followed by cortical visual impairment (18%). The most frequently used rehabilitation methods were: telescopic lenses (91.3%) for distance vision; magnifiers (38.7%) and telemicroscopic systems (26.0%) for near vision. A significant improvement in visual acuity both for distance and near vision were determined with low vision aids. Conclusion: A significant improvement in visual acuity can be achieved both for distance and near vision with low vision rehabilitation in partially sighted school-age children. It is important for ophthalmologists and pediatricians to guide parents and children to low vision rehabilitation.

    The clinical characteristics, treatment options and outcomes in patients with acute promyelocytic leukaemia (APL) and hyperleucocytosis remain poorly defined. This study reviewed 242 consecutive patients with APL; 29 patients (12%) had a white blood cell count (WBC) ≥ 50 × 10(9) /l at presentation (median WBC 85·5 × 10(9) /l). Patients with hyperleucocytosis had inferior complete remission (CR) rates (69% vs. 88%; P = 0·004) and higher 4-week mortality (24% vs. 9%; P = 0·018) compared to patients without hyperleucocytosis. We noted a trend towards inferior 3-year disease-free survival (DFS) (69% vs. 80%; P = 0·057) and inferior 3-year overall survival (OS) (74% vs. 92%; P = 0·2) for patients with hyperleucocytosis. Leukapheresis was performed in 11 (38%) of the 29 patients with hyperleucocytosis. CR rate and 3-year OS were not significantly improved in patients who received leukapheresis. CR rate and 3-year OS for the 15 patients with hyperleucocytosis treated with all-trans retinoic acid (ATRA) plus arsenic trioxide (ATO) plus cytotoxic therapy (idarubicin or gemtuzumab ozogamicin) combinations were 100% and 100% vs. 57% and 35% for the 14 patients treated with non-ATRA/ATO combinations (P = 0·004 and P = 0·002). Leukapheresis does not improve the outcomes in patients with APL presenting with hyperleucocytosis. ATRA/ATO-based combinations are superior to other regimens in these patients.

Patients commonly experience intolerable pruritus which may greatly affect their quality of life. Objective The objective of this study is to characterize the clinical patterns of pruritus in patients with urticarial dermatitis and to determine the effectiveness of cyclosporine treatment. Methods This prospective study included 50 histopathologically confirmed patients with urticarial dermatitis. A face-to-face structured questionnaire was given to all patients, and they were treated with low-dose cyclosporine (1~3 mg/kg/d) for at least 2 weeks. Results The majority of patients (80.0%) had moderate to severe pruritus. Most patients experienced exacerbation of the itch in the evening (74.0%), with the extremities (upper, 86.0%; lower, 94.0%) being the most commonly involved sites. Due to severe pruritus, patients complained about reduced social contact, quality of life and difficulties in falling asleep et al. Cyclosporine significantly reduced the mean itch score and extent of erythema, and improved interference with daily activities and sleep. Conclusion Our study highlights the detailed description and characteristics of pruritus in patients with urticarial dermatitis. And we recommend alternative and effective therapeutic option of low-dose cyclosporine.

    This study aimed to evaluate the frequency and clinical characteristics of hydroxychloroquine (HCQ) retinopathy in Korean patients with rheumatologic diseases. We retrospectively reviewed medical records of 310 patients taking HCQ. Ophthalmic examinations included spectral-domain optical coherence tomography (SD-OCT), automated visual field test, and fundus autofluorescence. The severity of retinopathy was categorized as early, moderate, or severe, and the location was categorized as parafoveal, pericentral, or mixed pattern. Among 310 patients, 9 patients (2.9%) were diagnosed as HCQ retinopathy. Among the patients with HCQ use ≥ 5 years (n = 174), the frequency was 5.2%. Only 1 (11.1%) of the 9 patients was symptomatic. The mean daily dose per kilogram of real body weight of the 9 patients was 5.6 mg, and only 3 had used 6.5 mg or more. Four of the 9 patients had severe HCQ retinopathy. Six of the 9 patients showed pericentral or mixed pattern of retinal damage. Consequently, the frequency of HCQ retinopathy in Korean patients was not low, especially when administered at a high cumulative dose and for a long duration. Screening of HCQ retinopathy by the recommended guidelines that include SD-OCT seems useful and should be done to detect retinal damage earlier in patients with chronic exposure to HCQ.

    Strict control of blood pressure is important to prevent cardiovascular disease, although it is sometimes difficult to decrease blood pressure to target levels. The aim of this study was to investigate the clinical characteristics of resistant hypertension evaluated by ambulatory blood pressure monitoring. One hundred in-hospital patients, whose 24-hour average blood pressure was higher than 130/80 mmHg even after treatment with more than three antihypertensive drugs, were included in the present analysis. Circadian variation of blood pressure was evaluated by nocturnal fall in systolic blood pressure. Average blood pressures of all patients were high in both daytime and nighttime, 150.0/82.9 and 143.8/78.2 mmHg, respectively. Twenty patients had been treated with hemodialysis or peritoneal dialysis. In 63 patients out of the other 80 patients (79%), estimated glomerular filtration rate (eGFR) was also decreased (blood pressure variation only by renal dysfunction. These results show that a large number of the patients with resistant hypertension suffered from renal dysfunction, although it was difficult to explain altered circadian blood pressure variation based on renal dysfunction alone.

    Patients with hypertensive crises, especially hypertensive emergencies, require immediate admittance to an intensive care unit for rapid blood pressure (BP) control. The authors analyzed the prevalence of hypertensive crisis, the clinical characteristics, and the evolution of patients with hypertensive emergencies and urgencies. Patients were divided into 3 groups according to their BP values: group I, predominant systolic hypertension (≥180/≤119 mm Hg); group II, severe systolic and diastolic hypertension (≥180/≥120 mm Hg); and group III, predominant diastolic hypertension (≤179/≥120 mm Hg). Of all of the patients admitted to a coronary care unit, 538 experienced a hypertensive crisis, which represented 5.08% of all admissions. Hypertensive emergency was predominant in 76.6% of the cases, which corresponded to acute coronary syndrome and acute decompensated heart failure in 59.5% and 25.2% of the cases, respectively. A pattern of predominant systolic hypertension (≥180/≤119 mm Hg) was most commonly observed in the hypertensive crisis group (71.4%) and the hypertensive emergency group (72.1%). The medications that were most commonly used at onset included intravenous vasodilators (nitroglycerin in 63.4% and sodium nitroprusside in 16.4% of the patients). The overall mortality rate was 3.7%. The mortality rate was 4.6% for hypertensive emergency cases and 0.8% for hypertensive urgencies cases.

    Background and aims Research on sexual addiction flourished during the last decade, promoted by the development of an increased number of online sexual activities. Despite the accumulation of studies, however, evidence collected in clinical samples of treatment-seeking people remains scarce. The aim of this study was to describe the characteristics (socio-demographics, sexual habits, and comorbidities) of self-identified "sexual addicts." Methods The sample was composed of 72 patients who consulted an outpatient treatment center regarding their sexual behaviors. Data were collected through a combination of structured interviewing and self-report measures. Results Most patients were males (94.4%) aged 20-76 years (mean 40.3 ± 10.9). Endorsement of sexual addiction diagnosis varied from 56.9% to 95.8% depending on the criteria used. The sexual behaviors reported to have the highest degree of functional impairment were having multiple sexual partners (56%), having unprotected sexual intercourse (51.9%), and using cybersex (43.6%). Ninety percent of patients endorsed a comorbid psychiatric diagnosis, and 60.6% presented at least one paraphilia. Conclusions Results showed highly different profiles in terms of sexual preferences and behaviors, as well as comorbidities involved. These findings highlight the need to develop tailored psychotherapeutic interventions by taking into account the complexity and heterogeneity of the disorder.

    In recent years, it has been reported that the frequency of DNA-methylation regulatory gene mutations - mutations of the genes that regulate gene expression through DNA methylation - is high in acute myeloid leukemia. The objective of the present study was to elucidate the clinical characteristics and prognosis of acute myeloid leukemia with associated DNA-methylation regulatory gene mutation. We studied 308 patients with acute myeloid leukemia. DNA-methylation regulatory gene mutations were observed in 135 of the 308 cases (43.8%). Acute myeloid leukemia associated with a DNA-methylation regulatory gene mutation was more frequent in older patients (Pgene mutation was an unfavorable prognostic factor for overall survival in the whole cohort (P=0.0018), in patients aged ≤70 years, in patients with intermediate cytogenetic risk, and in FLT3-ITD-negative patients (P=0.0409). Among the patients with DNA-methylation regulatory gene mutations, 26.7% were found to have two or more such mutations and prognosis worsened with increasing number of mutations. In multivariate analysis DNA-methylation regulatory gene mutation was an independent unfavorable prognostic factor for overall survival (P=0.0424). However, patients with a DNA-methylation regulatory gene mutation who underwent allogeneic stem cell transplantation in first remission had a significantly better prognosis than those who did not undergo such transplantation (P=0.0254). Our study establishes that DNA-methylation regulatory gene mutation is an important unfavorable prognostic factor in acute myeloid leukemia.

    Full Text Available Despite the increased global prevalence and recognition of autistic spectrum disorder (ASD, it is still scarcely reported in the Arab world. Though Israel has a higher prevalence of ASD, a previous national survey of patients diagnosed between 1972 and 2004, demonstrated that 98% of them were of Jewish ancestry. The disproportional low number of Arab children with ASD in Israel is unclear but may reflect lower awareness and cultural bias. In the present study we collected clinical and demographic characteristics of 200 children with ASD from Arab and Jewish sectors in Israel that were evaluated in two child development centers. We compared the incidence and the medical comorbidity of autism between these two ethnics groups. The medical and psychiatric comorbidity profile in these children was similar to the worldwide published studies. In the present study the prevalence of autism in the Arab sector in Israel was similar to that of the Jewish sector. The Arab patients presented with more severe autistic manifestations and higher incidence of mental retardation, familial members with autism, and consanguinity (P<0.05, while in the Jewish sector milder forms (such as Asperger syndrome and PDD-NOS were more frequent. This discrepancy might be explained by both genetic and cultural factors.

    Mathematics achievement in autism spectrum disorder (ASD) has been understudied. However, the ability to solve applied math problems is associated with academic achievement, everyday problem-solving abilities, and vocational outcomes. The paucity of research on math achievement in ASD may be partly explained by the widely-held belief that most individuals with ASD are mathematically gifted, despite emerging evidence to the contrary. The purpose of the study was twofold: to assess the relative proportions of youth with ASD who demonstrate giftedness versus disability on applied math problems, and to examine which cognitive (i.e., perceptual reasoning, verbal ability, working memory) and clinical (i.e., test anxiety) characteristics best predict achievement on applied math problems in ASD relative to typically developing peers. Twenty-seven high-functioning adolescents with ASD and 27 age- and Full Scale IQ-matched typically developing controls were assessed on standardized measures of math problem solving, perceptual reasoning, verbal ability, and test anxiety. Results indicated that 22% of the ASD sample evidenced a mathematics learning disability, while only 4% exhibited mathematical giftedness. The parsimonious linear regression model revealed that the strongest predictor of math problem solving was perceptual reasoning, followed by verbal ability and test anxiety, then diagnosis of ASD. These results inform our theories of math ability in ASD and highlight possible targets of intervention for students with ASD struggling with mathematics.

    Full Text Available Patients affected by psychotic disorders are more likely to develop high rates of co-morbidities , such as obesity, type 2 diabetes, dyslipidemias, hypertension, metabolic syndrome, myocardial infarction, stroke etc. in the long-term. These morbidities have a significant impact on the life-expectancy of these patients. Patients with chronic psychoses show a two- to three-fold increased risk of death mostly from cardiovascular and metabolic diseases. Although there may be an independent link between schizophrenia and metabolic conditions, the cardio-metabolic risk is mostly related to an unhealthy lifestyle and the usage of antipsychotic agents (especially Second Generation Antipsychotics or atypical even when these remain effective treatments in the management of major psychoses. Recently many international organizations have developed screening and monitoring guidelines for the control of modifiable risk factors in order to reduce the rate of co-morbidity and mortality among patients affected by schizophrenia. This paper is a review of current knowledge about the metabolic issues of patients affected by schizophrenia and describes clinical characteristics and medical management strategies for such conditions.

    Understanding the pathogenesis of recurrent urinary tract infection (RUTI) and whether it is attributable to reinfection with a new strain or relapse with the primary infecting strain is of considerable importance. Because previous studies regarding community-acquired Klebsiella pneumoniae RUTI are inconclusive, we undertook this study to evaluate the characteristics of the host and the bacterial agent K. pneumoniae in RUTI. A prospective study was designed, using consecutive patients diagnosed with community-acquired K. pneumoniae-related UTI from January 2007 to December 2009. Of the total 468 consecutive episodes, we found 7 patients with RUTI. All the patients with RUTI were elderly (median, 74 years), with diabetes (100 %, 7 out of 7). Clinical K. pneumoniae isolates derived from the same patients with RUTI revealed identical genomic fingerprints, indicating that K. pneumoniae UTI relapsed despite appropriate antibiotic therapy. The antimicrobial resistance, growth curve and biofilm formation of the recurrent isolates did not change. K. pneumoniae strains causing RUTI had more adhesion and invasiveness than the colonization strains (p recurrent strains with the community-acquired UTI strains, the prevalence of diabetes mellitus was significant (100 % vs 53.7 %, p = 0.03) in the RUTI group. Our data suggest that K. pneumoniae strains might be able to persist within the urinary tract despite appropriate antibiotic treatment, and the greater adhesion and invasiveness in the recurrent strains may play an important role in recurrent infections.

    Although high biocompatibility promotes the use of titanium (Ti) alloy in spinal implants, this material shows high stiffness, which is an issue for removal by drilling. The recently developed, porous Ti foam implants, which have shown enhanced osteoformation, may overcome this flaw. Thus, this study aimed to compare the mechanical and thermal characteristics of Ti-foam (80 % porosity) and conventional Ti alloy (0 % porosity) implants drilled in clinically relevant conditions. Mechanical properties were analyzed by measuring axial and torque forces using a pressure sensor with a drill of 2.5-mm diameter at a rotation frequency of 20 Hz. Thermography was used to evaluate the heat generated by a diamond burr attached to a high-speed (80,000 rpm) drill. The torque and axial strengths of Ti foam (13.63 ± 1.43 and 82.60 ± 7.78 N, respectively) were significantly lower (P = 0.001) than those of Ti alloy (73.58 ± 13.60 and 850.72 ± 146.99 N, respectively). Furthermore, irrigation reduced the area of local heating for Ti foam to 56-82 % of that for Ti alloy, indicating lower thermal conductivity. These data suggest that the use of Ti foam implants may be advantageous in cases with a probability of implant drilling in the future.

    Tendon and ligament injuries are common causes of impaired performance in equine athletes. Gray-scale ultrasonography is the current standard method for diagnosing and monitoring these injuries, however this modality only provides morphologic information. Elastography is an ultrasound technique that allows detection and measurement of tissue strain, and may provide valuable mechanical information about equine tendon and ligament injuries. The purpose of this study was to determine the feasibility, reproducibility, and repeatability of elastography; and to describe elastographic characteristics of metacarpal tendons in sound horses. Nineteen legs for 17 clinically sound horses without evidence of musculoskeletal pathology were included. Elastographic images of the superficial and deep digital flexor tendons and the branches of the suspensory ligament (tendon of the interosseous muscle) were described quantitatively and qualitatively. There was no statistically significant difference between operators (P = 0.86) nor within operators (P = 0.93). For qualitative assessments, reproducibility (0.46) was moderate and repeatability (0.78) was good. Similar to human Achilles tendons, equine tendons were classified as predominantly hard using elastography. There was no statistically significant difference in stiffness of the flexor tendons (P = 0.96). No significant difference in stiffness was found with altered leg position during standing (P = 0.84) and while nonweight bearing (P = 0.61). The flexor tendons were softer when imaged in longitudinal versus transverse planes (P tendons and ligaments of the distal forelimb in horses.

    Background In the summer of 2015, the exodus of Syrian war refugees and saturation of refugee camps in neighbouring countries led to the influx of asylum-seekers in European countries, including Belgium. This study aims to describe the demographic and clinical characteristics of asylum seekers who arrived in a huddled refugee camp, in the centre of a well-developed country with all medical facilities. Methods Using a descriptive cross-sectional study design, physicians of Médecins du Monde prospectively registered age, gender, origin, medical symptoms and diagnoses of all patients presenting to an erected field hospital in Brussels in September 2015. Diagnoses were post hoc categorised according to the International Classification of Diseases. Results Of 4037 patients examined in the field hospital, 3907 were included and analysed for this study. Over 11% of patients suffered from injuries, but these were outnumbered by the proportion of patients with respiratory (36%), dental (9%), skin (9%) and digestive (8%) diagnoses. More than 49% had features of infections at the time of the consultation. Conclusions Asylum seekers arriving in a refugee camp in Brussels after a long and hazardous journey suffer mostly from respiratory, dental, skin and digestive diseases. Still, one in seven suffers from injury. These findings, consistent with other reports, should be anticipated when composing emergency medical teams and interagency emergency health or similar kits to be used in a field hospital, even in a Western European country.

    AIM: To retrospectively analyze the pathogenesis, clinical characteristics, treatment and prognostic characteristics in patients with traumatic basal ganglia hematomas (TBGH).METHODS: A retrospective analysis of the clinical data was performed in 40 patients with TBGH who were selected from 1 250 patients with closed brain injury, who admitted to the Department of Neurosurgery of Shangqiu First People's Hospital from January 1990 to January 2004. The pathogenesis, clinical characteristics and signs, results of radiological examination, treatment and prognostic characteristics were analyzed. The patients all had definite history of brain injury, manifested by neurological functional disturbance to different extent after brain injury, and basal ganglia hemorrhage was identified by CT after brain injury, and hemorrhagic volume were more than or equal to 2 mL. Totally 34 males and 6 females were enrolled, aged 16-72 years and 28 cases of them were younger than 40 years old. The prognosis of the patients was evaluated with Glasgow outcome scale (GOS) at 6 months after injury, and GOS scoring standard was 1-5 points (1 for dead; 2 for vegetative survival, long-term coma, manifestations of decorticate rigidity or decerebrate rigidity; 3 for severely disabled, should be look after by others; 4 for moderately disabled, be able in self-care; 5 for good recovery, adults can work and study).RESULTS: The enrolled cases accounted for 3.20% of the 1250 patients with closed brain injury admitted at the same period. ① The causes of injury included traffic accident in 36 cases, fall in 2 cases, and assault in 2 cases. ② At admission, the Glasgow coma scale (GCS) scores were as follow: 13-15 scores (mild) in 10 cases,9-12 scores (moderate)in 20 cases, and 3-8 scores (severe) in 10 cases. Hemiplegia presented in 37 cases,aphasia in 20 cases, conscious disturbance in 10 cases, unilateral mydriasis in 6 cases, and decerebrate rigidity in 2 cases. ③ TBGH was detected by CT within

    Full Text Available The most important morphological feature of the immune response in lymphocytic-plasmacytic duodenitis (LPD in dogs is the presence of a mononuclear infiltrate in the duodenal mucosa. The ethiopatogenesis of this disease is still unknown, nor are known all the immunophenotypic characteristics of the infiltrate cells, which would be of help in the elucidation of the pathogenesis of LPD. The study involved 60 adult dogs of different breeds and both sexes: 54 dogs with symptoms of diarrhea and vomiting that lasted longer than three weeks and six clinically healthy dogs that served as controls. Hematological and biochemical analysis of blood, radiology, ultrasound and endoscopic diagnosis were carried out. Samples of duodenal mucosal biopta were examined by histopathological and immunohistochemical methods. During endoscopic examination, duodenal wall thickening, mucosal edema and hyperemia were observed in 46 dogs. Microscopic studies showed on the epithelial cells of the duodenum degenerative changes, and sometimes desquamation. Most of the intestinal crypts were dilated, irregularly shaped and filled with detritus. On immunohistochemical examination of samples of the duodenum in a number of dogs with LPD a predominant expression of CD3 + T lymphocytes was observed.

    Full Text Available The study aims at analyzing the epidemiological, clinical and entomological characteristics of Darfur yellow fever epidemic. It is a descriptive, cross-sectional study. According to operational case definition, suspected yellow fever cases are included in case spread sheet with variables like age, sex, locality, occupation, status of vaccination, onset of symptoms, presenting symptoms, date of blood sampling and confirmation of diagnosis either by laboratory results or epidemiological link. Data about important entomological indices were collected by surveys conducted in 17 localities of 3 Darfur states (Central, West and south Darfur. All Darfur states (especially Central Darfur have been affected by Yellow Fever outbreak. There is a need to review the non-specific case definition of Yellow Fever which seems to overwhelm the system during outbreaks with cases of other endemic diseases. The significant risk factors of this outbreak included male sex, adult age, outdoor occupation and traditional mining. The fatality rate was significantly associated with vaccination status. The highest fatality rate was recorded by children less than 2 years old (42.9%. Generally, increase in certain entomological indices was followed by increase in number of reported cases 7 days later. Central Darfur state was significantly higher in most studied entomological indices.

    AIM: To probe the pathological biological characteristics of hepatocellular carcinoma (HCC) by the ultrasound-guided aspiration biopsy and assess the clinical application value of this method.METHODS: The biopsy and DNA analysis by flow cytometry (FCM) were taken in 46 cases with HCC nodules, including 26 cases and 20 cases with nodules ≤3 cm and >3 cm in diameters respectively, and 12 cases with intrahepatic benign hyperplastic nodules. They were taken in 22 cases of 46cases with HCC before and after the therapy. Fine-needles and automatic histological incised biopsy needles were used.The fresh biopsy tissue was produced into the single cell suspension, which was sent for DNA detection and ratio analysis of cell period. The ratio of each DNA period of cell proliferation of each group was calculated and compared with each other. The DNA aneuploid (AN) and apoptosis cell peak were observed and their percentages were calculated.RESULTS: The ratios of S and G2/M periods of DNA, which reflect cell hyperproliferation, in the group with HCC tumors >3 cm in diameter were markedly higher than those of the group with HCC nodules ≤3 cm in diameter and the group with the benign hyperplastic nodules (P<0.01 except A:B of S period, P<0.05). The ratios of the middle group were also apparently higher than those of the latter group (P<0.01).The ratio of DNA AN of 46 cases with HCC nodules was 34.8 % (16/46). None of the cases with the intrahepatic hyperplastic nodules appeared AN. The DNA AN appeared more apparently with the growth of the tumors. The AN ratio of the group with tumors >3 cm in diameter was 55 %(11/20), markedly higher than that of the group with tumors ≤3 cm in diameter which was 19.2 % (5/26) (P<0.01). The FCM DNA analysis of 22 specimens of hepatic carcinoma tissue before therapy showed that the aneuploid peaks appeared in 5 cases (22.7 %). The ratio of G1 period rose after therapy while the S period and G2/M ratios fell (P<0.01).The

    Full Text Available A three-stage genome-wide association study recently identified single nucleotide polymorphisms (SNPs in five loci (fibroblast growth receptor 2 (FGFR2, trinucleotide repeat containing 9 (TNRC9, mitogen-activated protein kinase 3 K1 (MAP3K1, 8q24, and lymphocyte-specific protein 1 (LSP1 associated with breast cancer risk. We investigated whether the associations between these SNPs and breast cancer risk varied by clinically important tumor characteristics in up to 23,039 invasive breast cancer cases and 26,273 controls from 20 studies. We also evaluated their influence on overall survival in 13,527 cases from 13 studies. All participants were of European or Asian origin. rs2981582 in FGFR2 was more strongly related to ER-positive (per-allele OR (95%CI = 1.31 (1.27-1.36 than ER-negative (1.08 (1.03-1.14 disease (P for heterogeneity = 10(-13. This SNP was also more strongly related to PR-positive, low grade and node positive tumors (P = 10(-5, 10(-8, 0.013, respectively. The association for rs13281615 in 8q24 was stronger for ER-positive, PR-positive, and low grade tumors (P = 0.001, 0.011 and 10(-4, respectively. The differences in the associations between SNPs in FGFR2 and 8q24 and risk by ER and grade remained significant after permutation adjustment for multiple comparisons and after adjustment for other tumor characteristics. Three SNPs (rs2981582, rs3803662, and rs889312 showed weak but significant associations with ER-negative disease, the strongest association being for rs3803662 in TNRC9 (1.14 (1.09-1.21. rs13281615 in 8q24 was associated with an improvement in survival after diagnosis (per-allele HR = 0.90 (0.83-0.97. The association was attenuated and non-significant after adjusting for known prognostic factors. Our findings show that common genetic variants influence the pathological subtype of breast cancer and provide further support for the hypothesis that ER-positive and ER-negative disease are biologically distinct.

    Full Text Available Background. Endocrine Pancreatic Tumours (PENs are rare and can be nonfunctioning or functioning. They carry a good prognosis overall though high grade lesions show a relatively shorter survival. The aim of the current study is to describe a single centre analysis of the clinical characteristics and surgical treatment of PENs. Patients and Methods. This is a cohort analysis of 40 patients of PENs who underwent surgery at Sir Ganga Ram Hospital, New Delhi, India, from 1995 to 2013. Patient particulars, clinical features, surgical interventions, postoperative outcome, and followup were done and reviewed. The study group was divided based on grade (G1, G2, and G3 and functionality (nonfunctioning versus functioning for comparison. Results. PENs comprised 6.3% of all pancreatic neoplasms (40 of 634. Twenty-eight patients (70% had nonfunctioning tumours. Eighteen PENs (45% were carcinomas (G3, all of which were nonfunctioning. 14 (78% of these were located in the pancreatic head and uncinate process (P=0.09. The high grade (G3 lesions were significantly larger in size than the lower grade (G1 + G2 tumours (7.0 ± 3.5 cms versus 3.1 ± 1.6 cms, P=0.007. Pancreatoduodenectomy was performed in 18 (45%, distal pancreatectomy in 10 (25%, and local resection in 8 (20% and nonresective procedures were performed in 4 patients (10%. Fourteen patients (35% had postoperative complications. All G3 grade tumours which were resected had positive lymph nodes (100% and 10 had angioinvasion (71%. Eight neoplasms (20% were cystic, all being grade G3 carcinomas, while the rest were solid. The overall disease related mortality attributable to PEN was 14.3% (4 of 28 and for malignant PENs was 33.3% (4 of 12 after a mean follow-up period of 49.6 months (range: 2–137 months. Conclusion. Majority of PENs are nonfunctioning. They are more likely malignant if they are nonfunctioning and large in size, show cystic appearance, and are situated in the pancreatic head

Demographic, clinical, psychosocial, and behavioral characteristics of participants in the Counseling African American to Control Hypertension (CAATCH Trial are described. CAATCH evaluates the effectiveness of a multi-level, multi-component, evidence-based intervention compared with usual care (UC in improving BP control among poorly controlled hypertensive African Americans who receive primary care in Community Health Centers (CHCs. Methods Participants included 1,039 hypertensive African Americans receiving care in 30 CHCs in the New York Metropolitan area. Baseline data on participant demographic, clinical (e.g., BP, anti-hypertensive medications, psychosocial (e.g., depression, medication adherence, self-efficacy, and behavioral (e.g., exercise, diet characteristics were gathered through direct observation, chart review, and interview. Results The sample was primarily female (71.6%, middle-aged (mean age = 56.9 ± 12.1 years, high school educated (62.4%, low-income (72.4% reporting less than $20,000/year income, and received Medicaid (35.9% or Medicare (12.6%. Mean systolic and diastolic BP were 150.7 ± 16.7 mm Hg and 91.0 ± 10.6 mm Hg, respectively. Participants were prescribed an average of 2.5 ± 1.9 antihypertensive medications; 54.8% were on a diuretic; 33.8% were on a beta blocker; 41.9% were on calcium channel blockers; 64.8% were on angiotensin converting enzyme (ACE inhibitors/angiotensin receptor blockers (ARBs. One-quarter (25.6% of the sample had resistant hypertension; one-half (55.7% reported medication non-adherence. Most (79.7% reported one or more co-morbid medical conditions.

    Full Text Available BACKGROUND: Neonates with bacteremia are at risk of neurologic complications. Relevant information warrants further elucidation. STUDY DESIGN: This was a retrospective cohort study of neonates with bacteremia-related neurologic complications (BNCs in a tertiary-level neonatal intensive care unit (NICU. A systemic chart review was performed conducted to identify clinical characteristics and outcomes. A cohort of related conditions was constructed as the control group. Logistic regression analysis was used to identify independent risk factors for BNC. RESULTS: Of 1037 bacteremia episodes, 36 (3.5% had BNCs. Twenty-four cases of BNCs were related to meningitis, five were presumed meningitis, and seven occurred after septic shock. The most common causative pathogens were Group B streptococcus (41.7% and E. coli (16.7%. The major BNCs consisted of seizures (28, hydrocephalus (20, encephalomalacia (11, cerebral infarction (7, subdural empyema (6, ventriculitis (8, and abscess (4. Eight (22.8% neonates died and six (16.7% were discharged in critical condition when the family withdrew life-sustaining treatment. Among the 22 survivors, eight had neurologic sequelae upon discharge. After multivariate logistic regression analysis, neonates with meningitis caused by Group B streptococcus (adjusted odds ratio [OR]: 8.90, 95% confidence interval [CI]: 2.20-36.08; p = 0.002 and combined meningitis and septic shock (OR, 5.94; 95% CI: 1.53-23.15; p = 0.010 were independently associated with BNCs. CONCLUSIONS: Neonates with bacteremia-related neurologic complications are associated with adverse outcomes or sequelae. Better strategies aimed at early detection and reducing the emergence of neurologic complications and aggressive treatment of Group B streptococcus sepsis are needed in neonates with meningitis and septic shock.

    A blood culture (BC) is frequently requested in both patients with a suspected occult bacteremia/invasive infection as well as those with certain focal infections. Few data are available on the characteristics of patients in whom a bacteremia is identified in the Pediatric Emergency Department (PED). A prospective multicenter registry was established by the Spanish Pediatric Emergency Society. Epidemiological data, complementary test results, clinical management, and final outcome were recorded. Data from the first three years of the registry were analyzed. A true bacterial pathogen grew in 932 of 65,169 BCs collected [1.43 %; 95 % confidence interval (CI) 1.34-1.51 %], with 711 of them collected in patients without previously known bacteremia risk factors. Among them, 335 (47.1 %) were younger than 1 year old and 467 (65.7 %) had a normal Pediatric Assessment Triangle (PAT) on admission. Overall, the most frequently isolated bacterial species was Streptococcus pneumoniae (27.3 %; 47.6 % among patients with an altered PAT). The main pathogens were Escherichia coli (40.3 %) and S. agalactiae (35.7 %) among patients younger than 3 months, S. pneumoniae among patients 3-60 months old (40.0 %), and S. aureus (31.9 %) among patients over 60 months of age. Neisseria meningitidis was the leading cause of sepsis in patients older than 3 months. Eight patients died; none of them had a pneumococcal bacteremia and all had abnormal PAT findings on admission. S. pneumoniae is the main cause of bacteremia in patients without bacteremia risk factors who attended Spanish PEDs. Age and general appearance influence the frequency of each bacterial species. General appearance also influences the associated mortality.

    Full Text Available Purpose: To analyze the clinical and epidemiological characteristics of patients with uveitis in an emergency eye care center. Methods: We conducted a prospective, observational study of patients with active uveitis admitted between May 2012 and July 2012 to an emergency eye care center. Results: The majority of patients were male (63.2%, with a mean age of 43.2 years; 66.2% patients were of mixed ethnicity, 22.5% were Caucasian, and 11.3% were black. Anterior uveitis was observed in 70.1% patients, posterior uveitis in 26.5%, and panuveitis in 3.4%; no patient was diagnosed with intermediate uveitis. All patients had a sudden and acute presentation. The most frequent symptoms were ocular pain (76.9%, redness (59.8%, and visual blurring (46.2%. The majority of patients had unilateral disease (94.9% with a mean symptom duration of 6.2 days. Diffuse and anterior uveitis were associated with ocular pain (p<0.001. Scotomata and floaters were more frequent in patients with posterior uveitis (p=0.003 and p=0.016, respectively. Patients with anterior uveitis presented with better visual acuity (p=0.025. Granulomatous keratotic precipitates were more frequent in patients with posterior uveitis (p=0.038. An etiological diagnosis based on the evaluation at the emergency center was made in 45 patients (38.5%. Conclusions: Acute anterior uveitis was the most frequent form of uveitis. Initial patient evaluation provided sufficient information for deciding primary therapy and aided in arriving at an etiological diagnosis in a considerable number of patients.

    Background An atypical pattern of neonatal sepsis, characterized by persistent positive blood culture despite effective antimicrobial therapy, has been correlated with adverse outcomes. However, previous studies focused only on coagulate-negative staphylococcus infection. Methods All episodes of persistent bloodstream infection (BSI), defined as 3 or more consecutive positive blood cultures with the same bacterial species, at least two of them 48 hours apart, during a single sepsis episode, were enrolled over an 8-year period in a tertiary level neonatal intensive care unit. These cases were compared with all non-persistent BSI during the same period. Results We identified 81 episodes of persistent BSI (8.5% of all neonatal late-onset sepsis) in 74 infants, caused by gram-positive pathogens (n=38, 46.9%), gram-negative pathogens (n=21, 25.9%), fungus (n=20, 24.7%) and polymicrobial bacteremia (n=2, 2.5%). Persistent BSI does not differ from non-persistent BSI in most clinical characteristics and patient demographics, but tends to have a prolonged septic course, longer duration of feeding intolerance and more frequent requirement of blood transfusions. No difference was observed for death attributable to infection (9.8% vs. 6.5%), but neonates with persistent BSI had significantly higher rates of infectious complications (29.6% vs. 9.2%, P < 0.001), death from all causes (21.6% vs. 11.7%, P = 0.025), and duration of hospitalization among survivors [median (interquartile range): 80.0 (52.5-117.5) vs. 64.0 (40.0-96.0) days, P = 0.005] than those without persistent BSI. Conclusions Although persistent BSI does not contribute directly to increased mortality, the associated morbidities, infectious complications and prolonged septic courses highlight the importance of aggressive treatment to optimize outcomes.

Results (1) The diagnosis of PM infection in all the 12 cases were confirmed by peripheral blood culture.All the 12 cases (100%) had irregular fever (38-41 ℃) and enlarged lymph nodes, 8 cases (66%) had skin rashes; 8 cases (66%) had hepatomegaly; 9 cases (75%) had splenomegaly while 8 cases (66%) had anemia. (2) Imaging manifestation: Five cases manifested bilateral pulmonary disseminated miliary nodular shadows or lattice signs; 1 case showed enlarged hilar lymph node and 2 zases showed patchy shadow with pleuritis. One case presented sub-pleural curve line shadow at the posterior part of the right lower lung,and adhesion between the intestinal wall and intestinal mesentery in mass form in the abdomen by CT examination. Conclusion Patients suffering from AIDS (CD4T lymphocytes <50/μ L) with impaired immunity might be susceptible to complication of disseminated PM infection, which presents mainly damage of multiple organs and symptoms such as fever; enlargement of liver,spleen and lymph nodes, as well as specific skin maculopapular rashes. Imaging manifestations in the lungs were revealed as miliary nodular shadows and lattice-like shadows. Intensified abdominal CT might reveal presence of several enlarged postperitoneal lymph nodes and intestinal adhesion in shape of "cakes".

    Full Text Available Abstract Background The number of patients with non-HIV Pneumocystis pneumonia (PCP is increasing with widespread immunosuppressive treatment. We investigated the clinical characteristics of non-HIV PCP and its association with microbiological genotypes. Methods Between January 2005 and March 2010, all patients in 2 university hospitals who had been diagnosed with PCP by PCR were enrolled in this study. Retrospective chart review of patients, microbiological genotypes, and association with 30-day mortality were examined. Results Of the 82 adult patients investigated, 50 patients (61% had inflammatory diseases, 17 (21% had solid malignancies, 12 (15% had hematological malignancies, and 6 (7% had received transplantations. All patients received immunosuppressive agents or antitumor chemotherapeutic drugs. Plasma (1→3 β-D-glucan levels were elevated in 80% of patients, and were significantly reduced after treatment in both survivors and non-survivors. However, β-D-glucan increased in 18% of survivors and was normal in only 33% after treatment. Concomitant invasive pulmonary aspergillosis was detected in 5 patients. Fifty-six respiratory samples were stored for genotyping. A dihydropteroate synthase mutation associated with trimethoprim-sulfamethoxazole resistance was found in only 1 of the 53 patients. The most prevalent genotype of mitochondrial large-subunit rRNA was genotype 1, followed by genotype 4. The most prevalent genotype of internal transcribed spacers of the nuclear rRNA operon was Eb, followed by Eg and Bi. Thirty-day mortality was 24%, in which logistic regression analysis revealed association with serum albumin and mechanical ventilation, but no association with genotypes. Conclusions In non-HIV PCP, poorer general and respiratory conditions at diagnosis were independent predictors of mortality. β-D-glucan may not be useful for monitoring the response to treatment, and genotypes were not associated with mortality.

    Purpose Papillary thyroid carcinoma (PTC) arising from the pyramidal lobe is rare; therefore, clinicopathologic evaluation is lacking. In addition, the rate of occult malignancy in the pyramidal lobe after thyroid surgery is unclear. This study is to evaluate the clinical characteristics of PTCs that involve the pyramidal lobe. Methods The study enrolled 1,107 patients who underwent thyroid surgery for PTC at Seoul National University Hospital from 2006 to 2015. Pyramidal lobe status in pathologic reports was clear in all cases. “Pyramidal lobe-dominant PTC” was defined as single pyramidal lobe cancer or multifocal cancer with larger pyramidal lobe tumor. “Incidental pyramidal lobe PTC” was defined as occult cancer identified after thyroidectomy or as multifocal cancer with smaller pyramidal lobe tumor. Results Ten patients were included in the pyramidal lobe-dominant PTC group. The mean age was 58 ± 12.5 years, and the mean tumor size was 0.7 ± 0.7 cm. Cervical lymph node metastasis was found in 5 patients (50%). Three patients had microscopic lymphatic invasion, and 7 had advanced American Joint Comitee on Cancer (AJCC) stage disease (5 with stage III and 2 with stage IV). Compared with conventional PTC (n = 1,058), pyramidal lobe-dominant PTC was significantly associated with lymphatic invasion (P = 0.031) and advanced AJCC stage (P = 0.022). The prevalence of incidental pyramidal lobe PTC was 3.56%. Conclusion Pyramidal lobe PTC is relatively small in size; however, the rate of extrathyroidal extension and lymph node metastasis is high. Preoperative evaluation of nodal status is important, and the extent of surgery should be determined in accordance with the preoperative diagnosis. PMID:28289665

    Full Text Available Abstract Background A lot of studies have showed an excess maternal transmission of type 2 diabetes (T2D. The aim, therefore, of the present study was to estimate the prevalence of familial history of T2D in Greek patients, and to evaluate its potential effect on the patient's metabolic control and the presence of diabetic complications. Methods A total of 1,473 T2D patients were recruited. Those with diabetic mothers, diabetic fathers, diabetic relatives other than parents and no known diabetic relatives, were considered separately. Results The prevalence of diabetes in the mother, the father and relatives other than parents, was 27.7, 11.0 and 10.7%, respectively. Patients with paternal diabetes had a higher prevalence of hypertension (64.8 vs. 57.1%, P = 0.05 and lower LDL-cholesterol levels (115.12 ± 39.76 vs. 127.13 ± 46.53 mg/dl, P = 0.006 than patients with diabetes in the mother. Patients with familial diabetes were significantly younger (P 2, P = 0.08, higher prevalence of dyslipidemia (49.8 vs. 44.6%, P = 0.06 and retinopathy (17.9 vs. 14.5%, P = 0.08 compared with patients with no diabetic relatives. No difference in the degree of metabolic control and the prevalence of chronic complications were observed. Conclusion The present study showed an excess maternal transmission of T2D in a sample of Greek diabetic patients. However, no different influence was found between maternal and paternal diabetes on the clinical characteristics of diabetic patients except for LDL-cholesterol levels and presence of hypertension. The presence of a family history of diabetes resulted to an early onset of the disease to the offspring.

    Full Text Available INTRODUCTION Hepatoblastoma is the most frequent malignant liver tumour of childhood and it accounts for 1% of all paediatric cancers. The outcome is significantly improved by introducing intensive chemotherapy regimens followed by complete surgical tumour resection. The long-term survival is 75-95% at present. OBJECTIVE To summarize clinical characteristics and treatment results in children with hepatoblastoma. METHOD The patients diagnosed with hepatoblastoma and treated at the Department of Haematology of the University Children's Hospital in Belgrade, between January 1995 and December 2007 were retrospectively analyzed. We analyzed mode of therapy, surgical management and patients' survival according to Kaplan Mayer statistical test. RESULTS Eleven patients were treated (ten boys and one girl, aged from 6 months to 13 years, mean 32 months, median 12 months. The most frequent presenting sign was abdominal distension. Routine laboratory examination showed elevated alpha-fetoprotein (AFP, range 147 to 44880 ng/ml, mean 8667 ng/ml. Ten patients (91% had elevated platelet count, range 450 to 909x109/l. Initial lung metastasis developed in 3 patients (27%. The diagnosis was established by an open surgical biopsy in 6 patients and after complete tumour resection in 4 patients, namely 2 patients after preoperative chemotherapy and in 2 patients with no previous chemotherapy. Histopathology verified hepatoblastoma in 10 patients: in 7 patients with epithelial type and in 3 patients with mixed epithelial-mesenchyme type. Six patients were in continuous remission with mean follow up of 58 months. One patient was lost to follow up. Four patients died; three patients due to disease progression and one patient due to sepsis after the first cycle of chemotherapy. CONCLUSION Combined preoperative chemotherapy with complete tumour resection followed by postoperative chemotherapy results in a high percentage of definitive cures.

    Objective: To determine the incidence, timing, and associated clinical characteristics of objectively diagnosed pregnancy-associated venous thromboembolism (VTE).Methods: A retrospective review of VTE cases occurring between 1978 and 1996 was performed. Cases of deep venous thrombosis (DVT) and pulmonary embolism (PE) were identified by ICD-9 discharge diagnosis code and review of antepartum and coagulation laboratory databases. Study inclusion criteria required the objective diagnosis of VTE with either Doppler ultrasound, impedance plethysmography, pulmonary angiography, ventilation-perfusion scanning, or CT/MRI.Results: Among 268,525 deliveries there were 165 (0.06%) episodes of VTE (1/1627 births). There were 127 cases of DVT and 38 cases of PE. Only 14% (23/165) had a prior history of DVT or PE. Most DVTs occurred in the left leg (104/127, 81.9%). Nearly three quarters of the DVTs (95/127, 74.8%) occurred in the antepartum period. Among the antepartum DVT cases, half were detected prior to 15 weeks of gestation (47/95, 49.5%), with only 28 cases occurring after 20 weeks (P cesarean section. Only 1 patient developed PE while on heparin therapy for DVT while 11 others had complications attributable to heparin use.Conclusion: Most pregnancy-related VTE occurs in the antepartum period. The risk of deep venous thrombosis appears to begin early in pregnancy, even before the second trimester. The highest risk period for pulmonary embolism is after cesarean delivery. Maternal complications of heparin anticoagulation during pregnancy are rare.

    Background Adrenal insufficiency (AI) is a life-threatening disorder caused by the deficiency of adrenal steroid hormones. This retrospective cross-sectional study investigated the characteristics of patients with AI in Korea. Methods All consecutive patients with suspected AI who received care at a tertiary referral center in Korea in 2014 and underwent adrenocorticotropic hormone stimulation or insulin-tolerance testing were identified through a review of medical charts. Patients diagnosed with AI were enrolled. Their demographic, clinical, and treatment details were extracted. Results Of 771 patients with suspected AI, 183 (23.7%) received a definitive diagnosis. The most common reason for testing was the presence of suspicious AI-related symptoms (30.0%), followed by a history of steroid medications (23.5%). Their mean age was 66.7 years, and females predominated (67.8%). The most common symptoms were general weakness, anorexia, arthralgia, and fever. Approximately half (53.6%) had a history of steroid use. Hydrocortisone was the most common treatment (71.6%), with most patients taking a 30 mg dose (44.2%). The most common dose frequency was twice a day (78.6%). Fourteen patients were treated for adrenal crisis (n=10, 5.5%) or an intercurrent illness (n=4, 2.2%). Conclusion AI may have been caused by steroid medication use in many of the patients included in this study. The detection of AI can be improved by careful history-taking and being alert to the possibility that a patient has used steroids. PMID:28256113

    Full Text Available We assessed the clinical characteristics and efficacy of neurotransmitters and levetiracetam in a patient with hyperphenylalaninemia due to dihydropteridine reductase (DHPR deficiency who developed epileptic seizures. A boy with DHPR deficiency, who had been successfully treated with tetrahydrobiopterin (BH4, levodopa, and 5-hydroxytryptophan (5-HTP since he was 2 months old, started having monthly episodes of blurred vision, loss of consciousness, and falls at the age of 12 years. He was taking BH4 510 mg/day, levodopa 670 mg/day, 5-HTP 670 mg/day, and entacapone 300 mg/day. We evaluated the seizure semiology, EEG findings, and efficacy of levodopa, 5-HTP, and levetiracetam (LEV. His seizures were comprised of an abrupt loss of awareness and eye deviation to the right. Interictal EEG showed slightly slow posterior-dominant rhythm in 7–8 Hz; intermittent, irregular slowing in the bilateral parieto-occipital region; and multiregional independent spikes in bilateral hemispheres. Ictal EEG showed a seizure pattern starting at the left temporal region. Brain MRI showed diffuse signal increase of deep white matter on T2-weighted and FLAIR images. Dosage increase of levodopa to 1340 mg/day, of 5-HTP to 1500 mg/day, or of both did not suppress seizures. Levetiracetam 2000 mg/day markedly reduced seizures without any adverse events. Patients with DHPR deficiency can develop epileptic seizures of partial onset which can be successfully and safely treated with LEV.

    BACKGROUND: Carpal tunnel syndrome (CTS) is diagnosed mainly according to clinical symptoms, physical sign and neurodiagnostic laboratory examination. The therapeutic effect of conservative management and surgical operation in treating CTS need to be further observed and evaluated. OBJECTIVE: To analyze the clinical characteristics, neurophysiological grade and outcome in patients with CTS.DESIGN: Retrospective case-analysis.SETTING: Department of Neurology, First Affiliated Hospital, Medical College, Xi'an Jiaotong University. PARTICIPANTS: Totally 161 patients with suspected CTS from National Neuroscience Institute of Singapore referred to the Neurodiagnostic Laboratory for the confirmatory testing between January and September 2002. The involved patients, 137 male and 24 female, were aged 21-85 years. METHODS:①The condition of diabetes mellitus complicated by abnormal thyroid function was observed.②The effect on predominant hand, and paraesthesia were observed.③Neuroelectrophysiological studies were performed and the results were graded into mild, moderate and severe CTS according to the American Association of Electrodiagnostic Medicine (AAEM) criteria.④Conservative management and surgical intervention were followed up 3 months later, and symptoms and physical sign basically disappeared, and function was basically recovered, which indicated that disease condition improved.MAIN OUTCOME MEASURES:①Condition of CTS complicated by metabolic disease;②Effects on predominant hand and paraesthesia;③Electrophysiological grading; ④Prognosis.RESULTS: Totally 161 patients participated in the final analysis.①Condition of CTS complicated by metabolic disease: Among 161 patients, 17.4% (28/161) were documented to have diabetes mellitus and 7(4.3%) had hypothyroidism.②Effects on predominant hand and paraesthesia: Dominant hand involvement was present in 134 patients (83.2%) and more than 75% had onset of symptoms in the dominant hand.

    To accurately analyze the clinical characteristics of paroxysmal nocturnal hemoglobinuria (PNH) in different ethnic backgrounds, we retrieved all retrospective studies on clinical characteristics of PNH with a median follow-up period >60 months published after 2000, analyzed the clinical characteristics of PNH patients in Asia and European/America, and statistically compared enumeration data in these studies. We included 1665 patients in this analysis. The proportion of female patients in Asia was significantly lower than that in Europe/America (P = 0.000). Incidence rates of hemoglobinuria and thromboembolism in Asia were significantly lower than in Europe/America (both P values were 0.000). Within the subgroups of patients with thromboembolism, Asian patients had a higher proportion of arterial thrombosis while Western patients had a higher proportion of abdominal venous thrombosis. Bone marrow failure was not clearly defined in most studies. The proportion of patients with pancytopenia was higher in China than in France (P = 0.048). The total death rates were similar in both ethnic groups (P > 0.05). In Europe/America the major cause of death was thromboembolism and in Asian countries was serious infections. Differences in population characteristics of PNH patients among different ethnic groups indicate the possibility of differential pathogenesis and may be informative for treatment decisions.

    The aims of the study were to investigate the association between cytomorphology and immunophenotypic expression of CD34 cell surface antigen of blasts and their relationship with clinical and laboratory characteristics of patients with acute promyelocytic leukemia (APL). Sixteen consecutive patients (male 69% and female 31%) diagnosed with APL at Department of Hematology, Merkur University Hospital between August 1998 and December 2010 were included in the study. The mean age of patients was 43.9 (range: 18-78, SD 14.9). The patients' clinical and laboratory features, cytomorphological characteristics of APL-blasts and their immunophenotype determined by flow cytometry were analyzed. Patients were divided into two groups, CD34- and CD34+, and were then compared according to clinical and laboratory characteristics. There was no difference according to age, sex or white blood cell count between two groups. The mean value of hypogranular/agranular APL-blasts was markedly higher in CD34+ group than CD34- group (34%, range 9-60, SD 24.4 vs. 11.5%, range 0-38, SD 13.7), with borderline statistical significance (P=0.055). CD34- patients had significantly better overall survival than CD34+ ones (P=0.02). Patients without Auer rods detected in APL-blasts had higher CD34 expression (69.4% +/- 33.8) compared to patients with detected Auer rods (7.3% +/- 24.8), but statistical significance was not reached (p=0.053). Our results are consistent with the results of other published studies and point to the fact that higher CD34 expression and lower cytoplasmic granularity of APL-blasts are factors that seem to define a specific subgroup of APL patients. Together with other diagnostic tools currently available, they could be of value in planning treatment of APL patients.

    We aimed to examine the potential relationship between season of birth (SOB) and clinical characteristics in Korean patients with unipolar non-psychotic major depressive disorder (MDD). Using data from the Clinical Research Center for Depression (CRESCEND) study in South Korea, 891 MDD patients were divided into two groups, those born in spring/summer (n=457) and those born in autumn/winter (n=434). Measurement tools comprising the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Brief Psychiatric Rating Scale, Scale for Suicidal Ideation, Clinical Global Impression of severity, Social and Occupation Functional Assessment Scale, WHO Quality of Life assessment instrument-abbreviated version, Alcohol Use Disorder Identification Test, and Temperament and Character Inventory were used to evaluate depression, anxiety, overall symptoms, suicidal ideation, global severity, social function, quality of life, drinking, and temperament and character, respectively. Using independent t-tests for continuous variables and χ² tests for discrete variables, the clinical characteristics of the two groups were compared. MDD patients born in spring/summer were on average younger at onset of first depressive episode (t=2.084, p=0.038), had greater loss of concentration (χ²=4.589, p=0.032), and were more self-directed (t=2.256, p=0.025) than those born in autumn/winter. Clinically, there was a trend for the MDD patients born in spring/summer to display the contradictory characteristics of more severe clinical course and less illness burden; this may have been partly due to a paradoxical effect of the 5-HT system.
