    Full Text Available Clinical human brucellosis is quite rare in Malaysia although seroconverters are relatively more. This report describes a case of clinical human brucellosis in Malaysia. This case involved a 29-year-old research assistant in a veterinary microbiology laboratory. She complained of intermittent fever, anorexia, profuse sweating, malaise, headache, normotensive (110/60 mm Hg, muscle pain, and arthralgia for 3 d. Blood tests against dengue and malaria were negative thus she was prescribed vitamin C, paracetamol and cough syrup for common flu. The complaints, however, persisted on and off for the next 1 month. She eventually developed anemia and hypotension (90/50 mm Hg and started to show reduced body weight. Abdominal palpations revealed hepatomegaly and splenomegaly with pain. Thus, brucellosis was suspected before the Rose-Bengal plate test was performed, which revealed the presence of high level of antibody against Brucella. The same test was repeated after 14 d and the results confirmed the presence of high antibody level against Brucella. Following serum agglutination test, a diagnosis of brucellosis was made and she was eventually prescribed rifampicine p.o. once a day combined with doxycycline p.o. twice a day for 6 consecutive weeks before she made a full recovery.

    Full Text Available Abstract Background Previously thought to be rabies free, Bali experienced an outbreak of animal and human rabies cases in November 2008. We describe the epidemiological and clinical data of human rabies cases occurring in the first two years of the outbreak. Methods We analysed the patient records of all rabies cases from the Sanglah General Hospital in Denpasar, and district hospitals in Buleleng and Tabanan. A conventional reverse transcriptase polymerase chain reaction was developed to detect the rabies virus genome in saliva, corneal swabs, and ante- and post-mortem cerebrospinal fluid (CSF. Results There were 104 human rabies cases in Bali during November 2008-November 2010. Patients' mean age was 36.6 years (range 3-84 years; SD 20.7, most were male (56.7%, and originated from rural districts. Almost all (92% cases had a history of dog bite. Only 5.8% had their wounds treated and received an anti-rabies vaccine (ARV after the bite incident. No patients received rabies immunoglobulin (RIG. The estimated time from dog bite to the onset of signs and symptoms was 110.4 days (range 12-720 days; SD 118.2. The mean length of medical care until death was 21.8 hours (range 1-220 hours; SD 32.6. Less than 50% of patients had prodromal symptoms. The most frequent prodromal symptom was pain or paraesthesia at the bite site (37.6%. The two most common central nervous system infection signs were agitation (89.2% and confusion (83.3%. Signs of autonomic nervous system dysfunction included hydrophobia (93.1%, hypersalivation (88.2%, and dyspnea (74.4%. On admission, 22 of 102 patients (21.6% showed paralytic manifestations, while the rest (78.4% showed furious rabies manifestations. The case-fatality rate was 100%. The rabies virus genome was detected in 50 of 101 patients (49.5% with the highest detection rate from post-mortem CSF samples. Conclusions Rabies is a major public health problem in Bali. Human fatalities occur because of a lack of knowledge

    Full Text Available Gliomas are the most common primary brain tumors and yet almost incurable due mainly to their great invasion capability. This represents a challenge to present clinical oncology. Here, we introduce a mathematical model aiming to improve tumor spreading capability definition. The model consists in a time dependent reaction-diffusion equation in a three-dimensional spatial domain that distinguishes between different brain topological structures. The model uses a series of digitized images from brain slices covering the whole human brain. The Talairach atlas included in the model describes brain structures at different levels. Also, the inclusion of the Brodmann areas allows prediction of the brain functions affected during tumor evolution and the estimation of correlated symptoms. The model is solved numerically using patient-specific parametrization and finite differences. Simulations consider an initial state with cellular proliferation alone (benign tumor, and an advanced state when infiltration starts (malign tumor. Survival time is estimated on the basis of tumor size and location. The model is used to predict tumor evolution in two clinical cases. In the first case, predictions show that real infiltrative areas are underestimated by current diagnostic imaging. In the second case, tumor spreading predictions were shown to be more accurate than those derived from previous models in the literature. Our results suggest that the inclusion of differential migration in glioma growth models constitutes another step towards a better prediction of tumor infiltration at the moment of surgical or radiosurgical target definition. Also, the addition of physiological/psychological considerations to classical anatomical models will provide a better and integral understanding of the patient disease at the moment of deciding therapeutic options, taking into account not only survival but also life quality.

    Full Text Available BACKGROUND: While human cases of highly pathogenic avian influenza A (H5N1 virus infection continue to increase globally, available clinical data on H5N1 cases are limited. We conducted a retrospective study of 26 confirmed human H5N1 cases identified through surveillance in China from October 2005 through April 2008. METHODOLOGY/PRINCIPAL FINDINGS: Data were collected from hospital medical records of H5N1 cases and analyzed. The median age was 29 years (range 6-62 and 58% were female. Many H5N1 cases reported fever (92% and cough (58% at illness onset, and had lower respiratory findings of tachypnea and dyspnea at admission. All cases progressed rapidly to bilateral pneumonia. Clinical complications included acute respiratory distress syndrome (ARDS, 81%, cardiac failure (50%, elevated aminotransaminases (43%, and renal dysfunction (17%. Fatal cases had a lower median nadir platelet count (64.5 x 10(9 cells/L vs 93.0 x 10(9 cells/L, p = 0.02, higher median peak lactic dehydrogenase (LDH level (1982.5 U/L vs 1230.0 U/L, p = 0.001, higher percentage of ARDS (94% [n = 16] vs 56% [n = 5], p = 0.034 and more frequent cardiac failure (71% [n = 12] vs 11% [n = 1], p = 0.011 than nonfatal cases. A higher proportion of patients who received antiviral drugs survived compared to untreated (67% [8/12] vs 7% [1/14], p = 0.003. CONCLUSIONS/SIGNIFICANCE: The clinical course of Chinese H5N1 cases is characterized by fever and cough initially, with rapid progression to lower respiratory disease. Decreased platelet count, elevated LDH level, ARDS and cardiac failure were associated with fatal outcomes. Clinical management of H5N1 cases should be standardized in China to include early antiviral treatment for suspected H5N1 cases.

    Leptospira typing is carried out using isolated strains. Because of difficulties in obtaining them, direct identification of infective Leptospira in clinical samples is a high priority. Multilocus sequence typing (MLST) proved highly discriminatory for seven pathogenic species of Leptospira, allowing isolate characterization and robust assignment to species, in addition to phylogenetic evidence for the relatedness between species. In this study we characterized Leptospira strains circulating in Argentina, using typing methods applied to human clinical samples and isolates. Phylogenetic studies based on 16S ribosomal RNA gene sequences enabled typing of 8 isolates (6 Leptospira interrogans, one Leptospira wolffii and one Leptospira broomii) and 58 out of 85 (68.2%) clinical samples (55 L. interrogans, 2 Leptospira meyeri, and one Leptospira kirschneri). MLST results for the L. interrogans isolates indicated that five were probably Canicola serogroup (ST37) and one was probably Icterohaemorrhagiae serogroup (ST17). Eleven clinical samples (21.6%), provided MLST interpretable data: five were probably Pyrogenes serogroup (ST13), four Sejroe (ST20), one Autumnalis (ST22) and one Canicola (ST37). To the best of our knowledge this study is the first report of the use of an MLST typing scheme with seven loci to identify Leptospira directly from clinical samples in Argentina. The use of clinical samples presents the advantage of the possibility of knowing the infecting strain without resorting to isolates. This study also allowed, for the first time, the characterization of isolates of intermediate pathogenicity species (L. wolffii and L. broomii) from symptomatic patients.

    Full Text Available Abstract The genetic similarity of Campylobacter jejuni isolates from pets, compared to human clinical cases and retail food isolates collected in Ireland over 2001-2006 was investigated by cluster analysis of pulsed-field gel electrophoresis (PFGE fingerprinting profiles. Comparison of the PFGE profiles of 60 pet isolates and 109 human isolates revealed that seven (4.1% profiles were grouped in clusters including at least one human and one pet C. jejuni isolate. In total six (1.6% of 60 pet and 310 food profiles were in clusters with at least one food and one pet C. jejuni isolate. The detection of only a small number of genetically indistinguishable isolates by PFGE profile cluster analysis from pets and from humans with enteritis in this study suggests that pets are unlikely to be an important reservoir for human campylobacteriosis in Ireland. However, genetically indistinguishable isolates were detected and C. jejuni from pets may circulate and may contribute to clinical infections in humans. In addition, contaminated food fed to pets may be a potential source of Campylobacter infection in pets, which may subsequently pose a risk to humans.

    Modern pharmacometrics can integrate and leverage all prior proprietary and public knowledge. Such methods can be used to scale across species or comparators, perform clinical trial simulation across alternative designs, confirm hypothesis and potentially reduce development burden, time and costs. Crucial yet typically lacking in integration is the pre-clinical stage. Prediction of PK in man, using in vitro and in vivo studies in different animal species, is increasingly well theorized but could still find wider application in drug development. The aim of the present work was to explore methods for bridging pharmacokinetic knowledge from animal species (i.v. and p.o.) and man (p.o.) into i.v. in man using the antihistamine drug bilastine as example. A model, predictive of i.v. PK in man, was developed on data from two pre-clinical species (rat and dog) and p.o. in man bilastine trials performed earlier. In the knowledge application stage, two different approaches were used to predict human plasma concentration after i.v. of bilastine: allometry (several scaling methods) and a semi-physiological method. Both approaches led to successful predictions of key i.v. PK parameters of bilastine in man. The predictive i.v. PK model was validated using later data from a clinical study of i.v. bilastine. Introduction of such knowledge in development permits proper leveraging of all emergent knowledge as well as quantification-based exploration of PK scenario, e.g. in special populations (pediatrics, renal insufficiency, comedication). In addition, the methods permit reduction or elimination and certainly optimization of learning trials, particularly those concerning alternative off-label administration routes.

The clinical and laboratory results of a 42-year-old patient fulfilled criteria of confirm anaplasmosis and suggest an acute stage of illness. The described case provides strong presumptive evidence that infection in this patient was acquired with a pathogenic strain of A. phagocytophilum through a tick bite. A positive DNA with PCR for A. phagocytophilum infection was sequenced and analyzed phylogenetically. Physicians should consider the possibility of anaplasmosis in patients with early Lyme borreliosis, and A. phagocytophilum should be considered as a differential diagnosis in all patients from an endemic region of potential high risk factors for tick-borne diseases.

    We report the results of a 3-year Salmonella surveillance study of persons with diarrhea; asymptomatic children; and retail pork, poultry, and beef in Yucatan, Mexico. Isolates were characterized according to serotype, antimicrobial susceptibility, and genetic relatedness with pulsed-field gel electrophoresis. Salmonella Typhimurium was the most common serotype found in ill humans (21.8% of isolates), followed by Salmonella Agona (21% of isolates). Salmonella Enteritidis was a minor serotype (4.2% of isolates). Asymptomatic children carried S. Agona (12.1% of isolates), Salmonella Meleagridis (11.6% of isolates), Salmonella Anatum (8% of isolates) and S. Enteritidis (5.8% of isolates). A high percentage of retail meat samples contained Salmonella; it was most commonly found in pork (58.1% of samples), followed by beef (54% of samples) and poultry (39.7% of samples). Resistance to oral drugs used for the treatment of salmonellosis was observed for ampicillin (14.6% of isolates were resistant), chloramphenicol (14.0% of isolates), and trimethoprim-sulfamethoxazole (19.7% of isolates). Resistance to ceftriaxone emerged in 2002 and was limited to the serotype S. Typhimurium. Twenty-seven percent of the isolates were resistant to nalidixic acid, and none were resistant to ciprofloxacin. Multidrug resistance was most common among isolates of serotypes S. Typhimurium and S. Anatum. Pulsed-field gel electrophoresis showed that strains found in retail meats were genetically identical to strains found in both asymptomatic children and ill patients. Our study found a high prevalence of Salmonella in retail meats and persons with enteric infection; many of these isolates were resistant to clinically important antimicrobials. A random selection of isolates from people and retail meat showed genetic relatedness, which suggests that, in Yucatan, considerable transfer of Salmonella occurs through the food chain.

    Full Text Available Ampicillin-resistant Enterococcus faecium (ARE has rapidly emerged worldwide and is one of the most important nosocomial pathogens. However, very few reports are available on ARE isolates from canine clinical cases. The objective of this study was to characterize ARE strains of canine clinical origin from a veterinary teaching hospital in Canada and to compare them with human strains. Ten ARE strains from dogs and humans were characterized by multilocus sequence typing (MLST, pulsed field gel electrophoresis (PFGE, antibiotic susceptibility and biofilm activities, presence of rep-families, CRISPR-cas and putative virulence genes. All ARE strains (n = 10 were resistant to ciprofloxacin and lincomycin. Resistances to tetracycline (n = 6, macrolides (n = 6, and to high concentrations of gentamicin, kanamycin and streptomycin (n = 5 were also observed. Canine ARE isolates were found to be susceptible to vancomycin whereas resistance to this antibiotic was observed in human strains. Ampicillin resistance was linked to PBP5 showing mutations at 25 amino acid positions. Fluoroquinolone resistance was attributable to ParC, GyrA, and GyrB mutations. Data demonstrated that all canine ARE were acm (collagen binding protein-positive and that most harbored the efaAfm gene, encoding for a cell wall adhesin. Biofilm formation was observed in two human strains but not in canine strains. Two to five rep-families were observed per strain but no CRISPR sequences were found. A total of six STs (1, 18, 65, 202, 205, and 803 were found with one belonging to a new ST (ST803. These STs were identical or closely related to human hospital-associated lineages. This report describes for the first time the characterization of canine ARE hospital-associated strains in Canada and also supports the importance of prudent antibiotic use in veterinary medicine to avoid zoonotic spread of canine ARE.

    We developed a pharmacology practicum assignment to introduce students to the research ethics and steps involved in a clinical trial. The assignment included literature review, critical analysis of bioethical situations, writing a study protocol and presenting it before a simulated ethics committee, a practice interview with a faculty member to obtain informed consent, and a student reflective assessment and self-evaluation. Students were assessed at various steps in the practicum; the learning efficiency of the activity was evaluated using an independent survey as well as students' reflective feedback. Most of the domains of Bloom's and Fink's taxonomies of learning were itemized and covered in the practicum. Students highly valued the translatability of theoretical concepts into practice as well as the approach to mimic professional practice. This activity was within a pharmacy program, but may be easily transferable to other medical or health sciences courses.

    Comparative studies suggest that stem cells committed to a cardiac lineage are more effective for improving heart function than those featuring an extra-cardiac phenotype. We have therefore developed a population of human embryonic stem cell (ESC)-derived cardiac progenitor cells. Undifferentiated human ESCs (I6 line) were amplified and cardiac-committed by exposure to bone morphogenetic protein-2 and a fibroblast growth factor receptor inhibitor. Cells responding to these cardio-instructive cues express the cardiac transcription factor Isl-1 and the stage-specific embryonic antigen SSEA-1 which was then used to purify them by immunomagnetic sorting. The Isl-1(+) SSEA-1(+) cells were then embedded into a fibrin scaffold which was surgically delivered onto the infarct area in a 68-year-old patient suffering from severe heart failure [New York Heart Association [NYHA] functional Class III; left ventricular ejection fraction (LVEF): 26%]. A coronary artery bypass was performed concomitantly in a non-infarcted area. The implanted cells featured a high degree of purity (99% were SSEA-1(+)), had lost the expression of Sox-2 and Nanog, taken as markers for pluripotency, and strongly expressed Isl-1. The intraoperative delivery of the patch was expeditious. The post-operative course was uncomplicated either. After 3 months, the patient is symptomatically improved (NYHA functional Class I; LVEF: 36%) and a new-onset contractility is echocardiographically evident in the previously akinetic cell/patch-treated, non-revascularized area. There have been no complications such as arrhythmias, tumour formation, or immunosuppression-related adverse events. This observation demonstrates the feasibility of generating a clinical-grade population of human ESC-derived cardiac progenitors and combining it within a tissue-engineered construct. While any conclusion pertaining to efficacy would be meaningless, the patient's functional outcome yet provides an encouraging hint. Beyond this

    2009-01-01

    Full Text Available Background: Various studies worldwide suggest that human leukocyte antigen (HLA region may be involved in the genetic susceptibility of vitiligo but little information is available from India. Aim: To find the HLA associated susceptibility to develop vitiligo in Indian patients and to detect role of HLA in familial vitiligo. Methods: This was a case controlled study which included all patients suffering from vitiligo over a period of one and half years. Clinical details were noted and sera collected from these patients were screened for the presence of HLA class I antibodies. The clinical features and HLA antigens were assessed and comparison was made between patients with familial and nonfamilial vitiligo. Results: Out of 114 patients studied, 84 had family history and 30 had no family history. Patients with family history of vitiligo have higher chances of acquiring vitiligo if first degree relatives are affected compared to if second degree relatives are affected. Family history of vitiligo is associated with an early onset of vitiligo (< 20 years. There was no statistically significant difference in the type, stability, and severity of vitiligo in both the groups. HLA results in both the groups revealed increase in HLA A2, A11, A31, A33, B17, B35, B40, and B44 alleles while HLA A9, B13, and B53 alleles were decreased. Family history was associated with HLA A2, A28, A31, and B44 alleles. Early onset of vitiligo (< 20 years was significantly associated with HLA A2, A11, B17, B35, and B44 alleles. The patients with severe affection (> 10% area showed in significant association with HLA A10 and B8. Conclusion: Family history of vitiligo is associated with an early onset of vitiligo. There is no correlation of family history with the type of vitiligo, stability of lesions, and areas involved. Severity is not associated with family history. Apart from other alleles, alleles A2, and B44 play a significant role in vitiligo in the Indian patients.

    Full Text Available Encephalitis is a complex neurological disease that is associated with significant morbidity and mortality, and the etiology of the disease is often not identified. Human metapneumovirus (hMPV is a common cause of upper and lower respiratory tract infections in children. Few reports are available showing possible involvement of hMPV in development of neurologic complications. Here, we describe an infant, the youngest case in literature, with refractory status epilepticus and severe encephalitis in whom hMPV was detected in respiratory samples and review diagnostic workup of patient with encephalitis.

    Two recent, independent, studies conducted novel metabolomics analyses relevant to human sepsis progression; one was a human model of endotoxin (lipopolysaccharide (LPS)) challenge (experimental endotoxemia) and the other was community acquired pneumonia and sepsis outcome diagnostic study (CAPSOD). The purpose of the present study was to assess the concordance of metabolic responses to LPS and community-acquired sepsis. We tested the hypothesis that the patterns of metabolic response elicited by endotoxin would agree with those in clinical sepsis. Alterations in the plasma metabolome of the subjects challenged with LPS were compared with those of sepsis patients who had been stratified into two groups: sepsis patients with confirmed infection and non-infected patients who exhibited systemic inflammatory response syndrome (SIRS) criteria. Common metabolites between endotoxemia and both these groups were individually identified, together with their direction of change and functional classifications. Response to endotoxemia at the metabolome level elicited characteristics that agree well with those observed in sepsis patients despite the high degree of variability in the response of these patients. Moreover, some distinct features of SIRS have been identified. Upon stratification of sepsis patients based on 28-day survival, the direction of change in 21 of 23 metabolites was the same in endotoxemia and sepsis survival groups. The observed concordance in plasma metabolomes of LPS-treated subjects and sepsis survivors strengthens the relevance of endotoxemia to clinical research as a physiological model of community-acquired sepsis, and gives valuable insights into the metabolic changes that constitute a homeostatic response. Furthermore, recapitulation of metabolic differences between sepsis non-survivors and survivors in LPS-treated subjects can enable further research on the development and assessment of rational clinical therapies to prevent sepsis mortality

    Full Text Available Lumbar stenosis is an increasingly common pathological condition that is becoming more frequent with increasing mean life expectancy, with high costs for society. It has many causes, among which degenerative, neoplastic and traumatic causes stand out. Most of the patients respond well to conservative therapy. Surgical treatment is reserved for patients who present symptoms after implementation of conservative measures. Here, a case of severe stenosis of the lumbar spine at several levels, in a female patient with pathological and surgical antecedents in the lumbar spine, is presented. The patient underwent two different decompression techniques within the same operation.

    Evaluate the etiology and the most frequent funduscopic alterations of the neuroretinitis. We present the case of a woman 24 years old with a bilateral decrease of visual sharpness (AV), painless and progressive, the funduscopic examination of which reveals a bilateral optical disc edema, with no hemorrhages or exudates, retina edema of the posterior pole and phlebitic areas. The systematic study was normal except for the hemogram (18,000/mm(3) leucocytes with 79% neutrophils) and the positive serology next to a Chlamydia. We also present the case of a 64 years old woman with a decrease of AV at the right eye of one week duration. At the back of the eye a macular star can be seen, and papilla edema. A systematic study gave normal results and positive serology at Bartonella henselae. The illness produced by a cat scratch is the most common cause of neuroretinitis. The customary findings are a loss of AV, discromatopsia, afferent papillary defects and abnormality on the visual field. Other frequent findings at the back of the eye are hemorrhagic nerve fibers, cotton-like exudates, papilla edema, macular star and glassy inflammation. The roll of antibiotic therapy is questionable. Oral ciprofloxacine seems to give good results.

    Full Text Available Human parvovirus B19 is a well-known cause of severe conditions in patients with sickle cell disease, but the molecular mechanisms of the infection are insufficiently understood. The different clinical outcome of the acute parvovirus B19 infection in two pediatric patients with sickle cell disease has been examined. One of them developed life-threatening condition requiring emergency transfusions, while the other had asymptomatic infection, diagnosed occasionally. Both cases had high viral load and identical subgenotype, indicating that the viral molecular characteristics play a minimal role in the infection outcome.

    Ethylene glycol is a high production volume chemical used in the manufacture of resins and fibers, antifreeze, deicing fluids, heat transfer and hydraulic fluids. Although occupational uses of ethylene glycol have not been associated with adverse effects, there are case reports where humans have either intentionally or accidentally ingested large quantities of ethylene glycol, primarily from antifreeze. The acute toxicity of ethylene glycol in humans and animals and can proceed through three stages, each associated with a different metabolite: central nervous system depression (ethylene glycol), cardiopulmonary effects associated with metabolic acidosis (glycolic acid) and ultimately renal toxicity (oxalic acid), depending upon the total amounts consumed and effectiveness of therapeutic interventions. A physiologically based pharmacokinetic (PBPK) model developed in a companion paper (Corley et al., 2004) was refined in this study to include clinically relevant treatment regimens for ethylene glycol poisoning such as hemodialysis or metabolic inhibition with either ethanol or fomepizole. Such modifications enabled the model to describe several human case reports which included analysis of ethylene glycol and/or glycolic acid. Such data and model simulations provide important confirmation that the PBPK model developed previously can adequately describe the pharmacokinetics of ethylene glycol in humans following low, occupational or environmentally relevant inhalation exposures, as well as massive oral doses even under conditions where treatments have been employed that markedly affect the disposition of ethylene glycol and glycolic acid. By integrating the case report data sets with controlled studies in this PBPK model, it was demonstrated that fomepizole, if administered early enough in a clinical situation, can be more effective than ethanol or hemodialysis in preventing the metabolism of ethylene glycol to more toxic metabolites. Hemodialysis remains an

    Clinicians use various clinical reasoning tools such as Ishikawa diagram to enhance their clinical experience and reasoning skills. Failure mode and effects analysis, which is an engineering methodology in origin, can be modified and applied to provide inputs into an Ishikawa diagram. The human biliary system is used to illustrate a modified failure mode and effects analysis. The anatomical and physiological processes of the biliary system are reviewed. Failure is defined as an abnormality caused by infective, inflammatory, obstructive, malignancy, autoimmune and other pathological processes. The potential failures, their effect(s), main clinical features, and investigation that can help a clinician to diagnose at each anatomical part and physiological process are reviewed and documented in a modified failure mode and effects analysis table. Relevant medical and surgical cases are retrieved from the medical literature and weaved into the table. A total of 80 clinical cases which are relevant to the modified failure mode and effects analysis for the human biliary system have been reviewed and weaved into a designated table. The table is the backbone and framework for further expansion. Reviewing and updating the table is an iterative and continual process. The relevant clinical features in the modified failure mode and effects analysis are then extracted and included in the relevant Ishikawa diagram. This article illustrates an application of engineering methodology in medicine, and it sows the seeds of potential cross-pollination between engineering and medicine. Establishing a modified failure mode and effects analysis can be a teamwork project or self-directed learning process, or a mix of both. Modified failure mode and effects analysis can be deployed to obtain inputs for an Ishikawa diagram which in turn can be used to enhance clinical experiences and clinical reasoning skills for clinicians, medical educators, and students.

    Paralytic shellfish poisoning (PSP), a potentially fatal foodborne illness, is often diagnosed anecdotally based on symptoms and dietary history. The neurotoxins responsible for PSP, collectively referred to as the saxitoxins or paralytic shellfish toxins (PSTs), are natural toxins, produced by certain dinoflagellates, that may accumulate in seafood, particularly filter-feeding bivalves. Illnesses are rare because of effective monitoring programs, yet occasional poisonings occur. Rarely are contaminated food and human clinical samples (e.g., urine and serum) available for testing. There are currently few methods, none of which are validated, for determining PSTs in clinical matrices. This study evaluated AOAC (Association of Analytical Communities) Official Method of Analysis (OMA) 2005.06. [AOAC Official Method 2005.06 Paralytic Shellfish Poisoning Toxins in Shellfish: Prechormatographic Oxidation and Liquid Chromatography with Fluorescence Detection. In Official Methods of Analysis of AOAC International aoac.org>], validated only for shellfish extracts, for its extension to human urine and serum samples. Initial assessment of control urine and serum matrices resulted in a sample cleanup modification when working with urine to remove hippuric acid, a natural urinary compound of environmental/dietary origin, which co-eluted with saxitoxin. Commercially available urine and serum matrices were then quantitatively spiked with PSTs that were available as certified reference materials (STX, dcSTX, B1, GTX2/3, C1/2, NEO, and GTX1/4) to assess method performance characteristics. The method was subsequently applied successfully to a PSP case study that occurred in July 2007 in Maine. Not only were PSTs identified in the patient urine and serum samples, the measured time series also led to the first report of human PST-specific urinary elimination rates. The LC-FD data generated from this case study compared remarkably well to results obtained using AOAC OMA 2011.27 [AOAC

    The aim of the present study was to develop a method to study the healing process after gingival grafting and to observe the histologic results after use of the modified edentulous ridge expansion technique. A 47-year-old nonsmoking woman with a noncontributory past medical history affected by edentulism associated with a horizontal alveolar ridge defect was referred to the authors for surgical correction of the deficit to improve implant support and the final esthetics of an implant-borne prosthesis. At the 4-month follow-up visit, a biopsy was performed by a punch technique in the same sites of healing abutment connection. The tissue was elevated from the attached gingival. Clinically, the grafted tissues seemed to be attached to the bone surfaces. The histologic findings revealed dense grafted tissues, providing long-term stability to the area. No ligament or bone, characteristic for periodontal regeneration, were observed. The presence of thick attached keratinized tissue around implants may constitute a protective factor against marginal inflammation or trauma.

    PCR-based molecular diagnosis was made for the identification of causative agents of the clinically suspected pulmonary proliferative sparganosis case found in Thailand using formalin-fixed paraffin-embedded (FFPE) biopsy specimens. As a reference, FFPE biopsy specimen from a typical cutaneous sparganosis case was examined together. DNA samples were extracted from tissues and two partial fragments of cytochrome c oxidase subunit 1 (cox1) gene were amplified for the detection of Spirometra DNA. Two cox1 fragments were amplified successfully for both specimens. After alignment of nucleotide sequences of the PCR-amplicons, the causative agents of both cases were identified as Spirometra erinaceieuropaei.

    2014-03-01

    Full Text Available Dirofilarioses are zoonoses caused by filaria of the genus Dirofilaria, the parasites of domestic and wild animals. People are just random carriers of this parasite. In Europe, human dirofilariosis is caused by two species: Dirofilaria repens ( D. repens, also known as a species of The Old World , usually with the superficial localization of infection, and D. immitis, which is present throughout the world, and causes, beside superficial, visceral dirofilariosis. So far, based on the data from reference literature, it can be observed that in Serbia about 34 cases of human dirofilariosis have been diagnosed and published. It is assumed that the prevalence of this parasitosis is significantly higher as our country is an endemic area for dirofilariosis in dogs and the region where species of mosquitoes, which are transitory hosts and vectors of Dirofilaria spp., are present. The clinical picture of dirofilariosis depends on the type and location of the parasite in the human body. In our country, patients diagnosed with dirofilariosis had subcutaneous or subconjunctival infection in the majority of cases. Ocular dirofilariosis may affect the orbit and the periorbital region, the skin of the eyelids, the conjunctiva, the Tenon membrane, a retrobulbar space or has an intrabulbar localization. These patients may have a severe disability, and surgery alone can be complicated due to localization. The aim of this review is to highlight the importance of this unexpected important zoonoses, with special emphasis on the importance within the ophthalmic practice.

    Full Text Available Abstract Background Despite the increase in the number of clinical trials in low and middle income countries (LMICs, there has been little serious discussion of whether First in Human (FIH; phase 0 and phase 1 clinical trials should be conducted in LMICs, and if so, under what conditions. Based on our own experience, studies and consultations, this paper aims to stimulate debate on our contention that for products meant primarily for conditions most prevalent in LMICs, FIH trials should preferably be done first in those countries. Discussion There are scientific and pragmatic arguments that support conducting FIH trials in LMIC. Furthermore, the changing product-development and regulatory landscape, and the likelihood of secondary benefits such as capacity building for innovation and for research ethics support our argument. These arguments take into account the critical importance of protecting human subjects of research while developing capacity to undertake FIH trials. Summary While FIH trials have historically not been conducted in LMICs, the situation in some of these countries has changed. Hence, we have argued that FIH should be conducted in LMICs for products meant primarily for conditions that are most prevalent in those contexts; provided the necessary protections for human subjects are sufficient.

    Following the demise of apartheid, human rights in South Africa are now constitutionally enshrined.The right to health in South Africa's Constitution has been credited with transforming the lives of millions of people by triggering programmatic reforms in HIV treatment and the prevention of mother to child transmission (MTCT) of HIV.However, a constitutionally enshrined right to health offers no guarantee that clinical trial participants will enjoy post-trial access to beneficial interventions. Using access to HIV pre-exposure prophylaxis (PrEP) in South Africa as an example, this paper argues that adherence to bioethics norms could realize the right to health for trial participants following the end of a clinical trial.

    Pilocytic astrocytoma is a rare tumour, usually occurring in paediatric ages, and mainly located in the posterior fossa. It can cause hydrocephalus and intracranial hypertension and, less frequently, seizures, or a focal neurological deficit. The main imaging study by magnetic resonance imaging, which shows a tumour with solid and cystic components without peri-lesional swelling. The election treatment is surgical, and the patient is considered cured if a total resection is accomplished. The case is presented of 22-year-old female patient with a supratentorial pilocytic astrocytoma and epilepsy. Histopathology reported a low grade glial proliferation, with an extensive fibrillar matrix, small cells without atypia, extensive calcifications and piloid areas consisting of bipolar fusiform cells, and some Rosenthal fibres. There were also spongiotic areas consisting of multipolar cells and associated microcysts. The final report was a pilocytic astrocytoma. Pilocytic astrocytoma is more frequent in paediatric patients and in the posterior fossa. The case presented is of a young female adult with supratentorial location, making it a special case. The surgery achieved a total resection. The long-term prognosis is good, but it is necessary to perform a follow-up, particularly in adult patients because of a higher risk of recurrence.

    Control of Listeria monocytogenes in food processing facilities is a difficult issue because of the ability of this microorganism to form biofilms and adapt to adverse environmental conditions. Survival at high concentrations of sodium chloride and growth at refrigeration temperatures are two other important characteristics of L. monocytogenes isolates. The aim of this study was to compare the growth characteristics under stress conditions at different temperatures of L. monocytogenes serotypes responsible for the majority of clinical cases from different sources. Twenty-two L. monocytogenes isolates, 12 from clinical cases (8 serotype 4b and 4 serotype 1/2a) and 10 from food (6 serotype 4b and 4 serotype 1/2a), and an L. monocytogenes Scott A (serotype 4b) reference strain were analyzed for the ability to grow in brain heart infusion broth plus 1.9 M NaCl (11%) at 4, 10, and 25°C for 73, 42, and 15 days, respectively. The majority of L. monocytogenes strains was viable or even grew at 4°C and under the high osmotic conditions usually used to control pathogens in the food industry. At 10°C, most strains could adapt and grow; however, no significant difference (P > 0.05) was found for lag-phase duration, maximum growth rate, and maximum cell density. At 25°C, all strains were able to grow, and populations increased by up 5 log CFU/ml. Clinical strains had a significantly longer lag phase and lower maximum cell density (P food strains. Regarding virulence potential, no significant differences in hemolytic activity were found among serotypes; however, serotype 4b strains were more invasive in Caco-2 cells than were serotype 1/2a strains (P processed foods for health reasons may facilitate L. monocytogenes survival and growth in these products. Therefore, food companies must consider additional microbial growth barriers to assure product safety.

    An example of diagnostics and treatment of patient is in-process made with herpetic encephalitis. It is well-proven in researches, that a herpetic encephalitis is 11.5% among sharp encephalitises. Morbidity is sporadic, some researchers specify on an increase its spring. An infection can be passed tiny and pin a way. Seasonal vibrations are not incident to the herpetic encephalitis. Two peaks of morbidity are on 5-30 years and age more senior 50 years. More than in 95% cases the virus of simple herpes of type serves as an exciter of herpetic encephalitis 1. A characteristic triad of herpetic encephalitis is the sharp feverish beginning, development of cramps of dzheksonovskogo type and violation of consciousness, developing usually after a brief respirator infection. Sometimes sudden development of cramps and loss of consciousness is preceded a fever. Example of such development of disease is made an in our work.

    Objectives To understand whether aviation-derived human factors training is acceptable and useful to healthcare professionals. To understand whether and how healthcare professionals have been able to implement human factors approaches to patient safety in their own area of clinical practice. Methods Qualitative, longitudinal study using semi-structured interviews and focus groups, of a multiprofessional group of UK NHS staff (from the emergency department and operating theatres) who have received aviation-derived human factors training. Results The human factors training was evaluated positively, and thought to be both acceptable and relevant to practice. However, the staff found it harder to implement what they had learned in their own clinical areas, and this was principally attributed to features of the informal organisational cultures. Conclusions In order to successfully apply human factors approaches in hospital, careful consideration needs to be given to the local context and informal culture of clinical practice. PMID:24631959

    The debate between mentalism/cognitivism and behaviorism is analyzed, and it is concluded that behaviorism is the philosophy more closely associated with psychology as a behavioral science, the cognitive approach being more closely aligned with biological science. Specific objections to mentalistic interpretations of behavioral phenomena are detailed, and examples from clinical psychology are used to show the importance of behavioral approaches in applied domains. It is argued that the relation between behavior theory and clinical psychology is critical to the continued advancement of applied psychology. Behavior analysis is offered as a direct, applied extension of behavior theory as well as a highly practical and effective approach for understanding, explaining, and modifying the factors that contribute to and maintain maladaptive behaviors.

    Learning how to 'think like doctors' can be difficult for undergraduate medical students in their early clinical years. Our model of collaborative Integrated Case Learning (ICL) and simulated clinical reasoning aims to address these issues. Taking a socio-cultural perspective, this study investigates the reflective learning interactions and practices of clinical thinking that emerged in the ICL environment. We also explore how third year medical students perceived their ICL experiences in relation to the clinical situations encountered in the hospital setting. The context for the inquiry is a rural Clinical School in North West Victoria, Australia. We used a qualitative case study methodology following eight third-year medical students over an academic year. Individual and group interviews were conducted, together with observations and document/artefact analysis. Data was analysed using content and narrative methods. The ICL program was well received. Findings suggest that the group-based, simulated clinical reasoning process appears to help undergraduate medical students to rehearse, articulate and question their clinical decision-making pathways. We argue that the ICL process offers a professionally challenging, but supportive group learning 'space' for students to practise what it might mean to 'think', 'talk' and 'perform' like doctors in real settings. The ICL environment also appears to create a connective bridge between the 'classroom' and clinical practice.

    The authors report a clinical case of a 41-years-old man with astenia and myalgias maintained for many years without an accurate diagnosis. Amyopathic dermatomyositis was diagnosed based on the presence of typical cutaneous lesions and the absence of myositis. Subsequent evidence of subclinical myositis allowed the diagnosis of hypomyophatic dermatomyositis. Finally, the diagnosis of classical dermatomyositis could be made when the patient presented elevated levels of muscle enzimes. There was a good clinical response to imunossupressor therapy and the patient remains asymptomatic. Differences in the clinical management of amyopathic, hypomyopathic and classic dermatomyositis are discussed.

    Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. The case study demonstrates that trials need various categories of people to buy in - hence, to be successful, trialists must embrace marketing strategies to some extent. The performance of future clinical trials could be enhanced if trialists routinely considered these factors.

    Many patients present to the breast clinic with variable symptoms. The degree of palpability is the important symptom for patients and clinicians. Both mammography and ultrasonography play an important role in the diagnosis of breast diseases by indicating the cause of the symptoms and aiding in the selection of treatment for the disease. Sometimes, however, we meet unexpected results. In this paper, we will illustrate the ultrasonographic and mammographic findings of interesting, unusual or perplexing breast cases in order to familiarize ourselves with these breasts through these cases and thereby assist in future diagnosis

    In this Open Forum a psychiatric health care consumer recounts his experience with his state's requirement to hold case management meetings outside of the clinic. Over time, the author found that meeting elsewhere amounted to being put on public display, and he felt embarrassed and powerless to change the situation. Requiring people with psychiatric disorders to meet outside a clinical setting may violate the Health Insurance Portability and Accountability Act and human rights. This New Hampshire state policy needs to be changed because it undermines treatment and reinforces the stigma that many consumers already feel because of their disability.

    Full Text Available American cutaneous leishmaniasis includes a spectrum of clinical forms localized cutaneous, diffuse cutaneous, and mucocutaneous leishmaniasis which can be caused by different strains of Leishmania belonging to the L. mexicana or L. braziliensis complexes which may coexist in the same endemic area. We evaluated the PCR-RFLP assay of the ITS1 genes for direct identification of Leishmania species in 163 clinical samples and 21 Mexican isolates of Leishmania. In relation to the Mexican isolates of Leishmania 52% displayed a pattern similar to the L. (L. mexicana, 5% showed a mixed pattern compatible with L. (L. mexicana and L. (V. braziliensis, eight with L. (L. amazonensis and L. (L. mexicana, and one to L. (V. braziliensis. Most of the clinical samples, 109/116 (94%, gave a pattern similar to that of the L. mexicana, two clinical samples gave similar patterns to that of Leishmania braziliensis, and 5 samples gave patterns that suggest a coinfection of L. (L. mexicana and L. (V. braziliensis or L. (L. mexicana and L. (L. amazonensis. The ITS1 PCR-RFLP assay is a multipurpose tool for diagnosis of Leishmania from clinical samples and enables determination of the infecting species of New World Leishmania in the field in relatively short time and low cost.

    Maintaining healthy parodontium during teeth restoration procedures is an indispensable condition for obtain- ing regular functionning and esthetics. Thus, the knowledge of correct anatomy and the influence of filling and complement on paradontium tissue is vital. Difficulty in maintaining appropriate gingival biological width (GBW) is a frequent problem encountered in this type of reconstruction. Preservation of unchanged biological width conditions predictible treatment result and, what is more, lack of inflammatory lesions in marginal parodontium. The ideal situation for parodontium is localizing the filling/complement border supragingivaly, which is at least 3 mm from alveolar process edge. In the case, when the above conditions are impossible to fulfil, elongation of clinical crown is a metod of choice. The effect is possible to achieve by surgical treatment or combined orthodontic - surgical treatment. Surgical treatment is faster and preferred procedure for indirect reconstruction, where achieving high clinical crown is necessary. Three clinical cases of performing method of surgical clinical crown elongation were presented in the article. Performing the described procedure enables correct tooth crown reconstruction and, what is most important, keeping individual toothing.

    2012-10-01

    Full Text Available Abstract Over the past 20 years, several proton beam treatment programs have been implemented throughout the United States. Increasingly, the number of new programs under development is growing. Proton beam therapy has the potential for improving tumor control and survival through dose escalation. It also has potential for reducing harm to normal organs through dose reduction. However, proton beam therapy is more costly than conventional x-ray therapy. This increased cost may be offset by improved function, improved quality of life, and reduced costs related to treating the late effects of therapy. Clinical research opportunities are abundant to determine which patients will gain the most benefit from proton beam therapy. We review the clinical case for proton beam therapy. Summary sentence Proton beam therapy is a technically advanced and promising form of radiation therapy.

    Full Text Available The annual incidence of adult-onset Still's disease (AOSD worldwide is 0.16 cases per 100,000 persons. Its leading symptoms are joint involvement, fever, skin rash, and neutrophilic leukocytosis in the absence of rheumatoid factor and anticyclic citrullinated peptide antibodies in serum and synovial fluid. In its initial stage, there may be monoarthritis more commonly of the wrist, hip, or knee. Then the lesion assumes the pattern of oligo- or polyarthritis. Musculoskeletal involvement appearing as arthralgia, arthritis, and myalgia is noted in all patients. In the majority of patients, articular involvement progresses and destructive polyarthritis develops. Symmetric involvement of the carpophalangeal and distal interphalangeal joints is frequently detected. Skin lesion manifests itself as maculopapular or roseolous rashes on the chest, back, shoulders, occasionally on the legs, or in the areas of mechanical irritation. A sore throat with the signs of pharyngitis is a characteristic early symptom of the disease. There may be involvements of the liver, cardiovascular system, lung, as well as lymphadenopathy, or splenomegaly. The chronic course of the disease is more frequently noted.The paper describes two cases of AOSD. One case demonstrates that the physician has no experience in diagnosing and managing patients with AOSD, resulting in the misinterpretation of the increase in disease activity when the subclinical doses of methotrexate (MT are used, which has been regarded as a therapeutic complication. The use of the adequate dose of MT could achieve a clinical and laboratory remission and discontinue glucocorticoids (GC.In the other case of recurrent AOSD and mild clinical symptoms, the unreasonable use of high GC doses gave rise to adverse reactions.

    Full Text Available Pur po se: To evaluate the etiological factors, diagnosis, follow-up and treatment procedures in cases of orbital cellulitis. Ma te ri al and Met hod: A retrospective review was performed on medical records of patients with orbital cellulitis treated between 2009 and 2011 in our clinic. The patients were studied for age, ophthalmologic examination features, laboratory and radiology results, treatment modalities and the response to these treatments. Re sults: Eleven patients (7 male, 4 female having an average age of 9.7 years (6 months-25 years participated in the study. All patients had eyelid oedema, hyperemia and ocular pain; with chemosis in 3, gaze restriction in 6, relative afferent pupillary defect and proptosis in 4 cases. Orbital cellulitis was observed to occur secondary to paranasal sinusitis in 10 patients (90.9% and 1 patient had only history of superior respiratory tract infection. Sinus infection was localized in ethmoid and maxillary sinuses in all except one case. Laboratory tests showed leukocytosis in 8 patients. Surgical drainage was performed in 7 of 8 patients with abscess formation observed with radiological imaging. The remainder of the patients were followed with sole medical treatment. All patients recovered without any vision loss or life-threatening complication. Dis cus si on: Orbital cellulitis cases must be followed with radiologic imaging for any complication that may occur and patients with abscess should be evaluated for surgical drainage besides antimicrobial treatment.(Turk J Ophthalmol 2012; 42: 284-7

    The most common surgery performed in our clinic with the CO2 laser is the cutting and vaporization of neoplasms associated with the head and neck, in particular, the squamous cell carcinoma in the cat. A majority of the tumors are malignant and 50% are metastatic at the time of presentation for surgery. Experience has taught us that early detection and removal with the CO2 laser affords the best prognosis. To date, roughly 100 cases have been treated with the CO2 laser. The success rate in the dog is not as rewarding as in the cat. Most cases were done with 5 - 10 watts of power continuous or pulsed wave, using a 125 mm or 50 mm handpiece. The laser beam was focused or defocused to adjust for cutting, vaporization, and coagulation. No post-op care of the wounds was recommended. Other small neoplasms in and around the ears, head, and neck can also be removed easily with the CO2 laser.

    Full Text Available Human dirofilariasis is a zoonotic infectious disease caused by the filarial nematodes of dogs Dirofilaria repens and Dirofilaria immitis. Depending on the species involved, human infections usually manifest as one cutaneous or visceral larva migrans that forms a painless nodule in the later course of disease. Dirofilariae are endemic in the Mediterranean, particularly in Italy. They are considered as emerging pathogens currently increasing their geographical range. We present one of the few known cases of human dirofilariasis caused by D. repens in Romania. The patient developed unusual and severe clinical manifestations that mimicked pathological conditions like cellulitis or deep venous thrombosis.

    Full Text Available Objective: We present a clinical case of an old woman who suffered at different ages surgical excisions for three different primarymalignant tumors. The patient is now 86 years old. She was diagnosed at the age of 35 with a malignant tumor of the corpus uteri, and thenwhen she was 78 with a basocellular carcinoma of the nose skin and at 81 she was diagnosed with an ascendant large bowel adenocarcinoma.Despite the occurrence of three different tumors she is alive five years later and cancer-free, but suffering because of other medical diseasesincluding diabetes, hypertension, myocardial ischemia and migraines. Conclusion: a patient diagnosed with a cancer and who survive from itmust be submitted to periodically medical controls because of the possibility to develop several other cancers. With an increasing survival inpatients after malignant tumors therapy, there is an increased risk to develop other cancers as the patients are getting older.

  15. Review of clinical and laboratory features of human Brucellosis

    2007-01-01

    Full Text Available Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. Brucellosis has been an emerging disease since the discovery of Brucella melitensis by Sir David Bruce in 1887. Although many countries have eradicated B. abortus from cattle, in some areas B. melitensis and B. suis have emerged as causes of this infection in cattle, leading to human infections. Currently B. melitensis remains the principal cause of human brucellosis worldwide including India. The recent isolation of distinct strains of Brucella from marine mammals as well as humans is an indicator of an emerging zoonotic disease. Brucellosis in endemic and non-endemic regions remains a diagnostic puzzle due to misleading non-specific manifestations and increasing unusual presentations. Fewer than 10% of human cases of brucellosis may be clinically recognized and treated or reported. Routine serological surveillance is not practiced even in Brucella - endemic countries and we suggest that this should be a part of laboratory testing coupled with a high index of clinical suspicion to improve the level of case detection. The screening of family members of index cases of acute brucellosis in an endemic area should be undertaken to pick up additional unrecognised cases. Rapid and reliable, sensitive and specific, easy to perform and automated detection systems for Brucella spp. are urgently needed to allow early diagnosis and adequate antibiotic therapy in time to decrease morbidity / mortality. The history of travel to endemic countries along with exposure to animals and exotic foods are usually critical to making the clinical diagnosis. Laboratory testing is indispensable for diagnosis. Therefore alertness of clinician and close collaboration with microbiologist are essential even in endemic areas to correctly diagnose and treat this protean human infection. Existing treatment options, largely based on

  19. Imported human rabies cases worldwide, 1990-2012.

    Directory of Open Access Journals (Sweden)

    Philippe Carrara

    Full Text Available Sixty cases of human rabies in international travelers were reviewed from 1990-2012. A significant proportion of the cases were observed in migrants or their descendants when emigrating from their country of origin or after a trip to visit friends and relatives or for other reasons (43.3%. The cases were not necessarily associated with long-term travel or expatriation to endemic countries; moreover, cases were observed in travelers after short trips of two weeks or less. A predominance of male patients was observed (75.0%. The proportion of children was low (11.7%. Cases from India and Philippines were frequent (16 cases/60. In a significant proportion of cases (51.1%, diagnosis was challenging, with multiple missed diagnoses and transfers from ward to ward before the final diagnosis of rabies. Among the 28 patients whose confirmed diagnosis was obtained ante-mortem, the mean time between hospitalization and diagnosis was 7.7 days (median time: 6.0 days, range 2-30 including four cases with a diagnosis delayed by 15 or more days. In five cases, a patient traveled through one or more countries before ultimately being hospitalized. Three factors played a role in delaying the diagnosis of rabies in a number of cases: (i a low index of suspicion for rabies in countries where the disease has been eradicated for a long time or is now rare, (ii a negative history of animal bites or exposure to rabies, and (iii atypical clinical presentation of the disease. Clinical symptomatology of rabies is complex and commonly confuses physicians. Furthermore, failure in diagnosing imported cases in more developed countries is most likely related to the lack of medical familiarity with even the typical clinical features of the disease.

    Full Text Available Introduction: In this environment, previous workers have reported on the challenges of managing large sized ameloblastoma of the jaws with less than adequate facilities. The aim of this review is to present the management of 68 cases of ameloblastoma with emphasis on surgical care. Materials and Methods: Retrospective survey of case notes of patients with histopathologic diagnosis of ameloblastoma (using the criteria of Barnes et al., 2005 seen between January 2006 and August 2010 at the Maxillofacial Unit, Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria was undertaken. Data collected includes histopathological diagnosis, age, gender, clinical information on site of lesion, form of intubation and surgical procedure performed. Results: Out of 94 patients, 68 with histological diagnosis of ameloblastoma (59 mandibular and 9 maxillary were operated within the study period. The remainder (26 was not treated in hospital. Among 68 patients treated, more were males (38 than females (30, giving a male to female ratio of 1.3:1. The age range was between 14 and 74 years (mean-standard deviation. The duration of the symptoms ranged from 7 months to 24 years, most were follicular ameloblastoma (n = 13 followed by acanthomatous type (n = 7. Endotracheal intubation was the most common (n = 55 followed by fiber optic laryngoscopy (n = 8. The surgical approach most used was extended Risdon with intraoral (n = 24 followed by extended Risdon with lip split and intraoral (n = 17. Segmental resection (en block formed the bulk of our procedures (n = 22 followed by subtotal mandibulectomy (n = 16. Conclusion: The treatment of ameloblastoma remains controversial. Its destructive nature has left patients with wide defects difficult to reconstruct.

    Dengue is an infectious disease caused by a flavivirus, with four serotypes, transmitted by the mosquito Aedes aegypti. In Mexico it is a public health problem, especially in the region of central and southeast of the country. The disease can be asymptomatic or present serious forms and even death. It is confirmed by detection of the NS1 Antigen; IgM antibodies, polymerase chain reaction and virus isolation. The vertical transmission to de newborn has been little studied. 7 cases in neonates from November to December 2011 are reported. All patients were male, obtained by caesarean section between 34 and 40 weeks of gestation, whose mothers were enrolled with fever and symptoms associated with dengue disease and serology positive for dengue. Six with positive AgNS1 and one positive IgM; one mother died. All the newborns had positive serology for dengue, 4 with positive AgNS1 and 3 positive IgM. The clinical features of the newborn ranged from asymptomatic to one serious dengue fever, shock and hemorrhage. The symptomatic 6 attended with thrombocytopenia, changes in temperature and unspecific disturbance. The severity of mothers conditioned disrepair product at birth, but not with subsequent gravity of the new born. Vertical trasmission of dengue should be suspected in risk areas, to maintain vigilance and to give early treatment. Also is neccesary promote the realization of specific diagnostic and therapeutic guidelines to the neonatal period.

    The recombination-activating gene 1 (RAG1) and RAG2 proteins initiate the V(D)J recombination process, which ultimately enables the generation of T cells and B cells with a diversified repertoire of antigen-specific receptors. Mutations of the RAG genes in humans are associated with a broad spectrum of clinical phenotypes, ranging from severe combined immunodeficiency to autoimmunity. Recently, novel insights into the phenotypic diversity of this disease have been provided by resolving the crystal structure of the RAG complex, by developing novel assays to test recombination activity of the mutant RAG proteins and by characterizing the molecular and cellular basis of immune dysregulation in patients with RAG deficiency.

    Human intestinal capillariasis is a rare parasitosis that was first recognized in the Philippines in the 1960 s. Parasitosis is a life threatening disease and has been reported from Thailand, Japan, South of Taiwan (Kaoh-Siung), Korea,Tran, Egypt, Italy and Spain. Its clinical symptoms are characterized by chronic diarrhea, abdominal pain,borborygmus, marked weight loss, protein and electrolyte loss and cachexia. Capillariasis may be fatal if early treatment is not given. We reported 14 cases living in rural areas of Taiwan. Three cases had histories of travelling to Thailand. They might have been infected in Thailand while stayed there. Two cases had the diet of raw freshwater fish before. Three cases received emergency laparotomy due to peritonitis and two cases were found of enteritis cystica profunda. According to the route of transmission,freshwater and brackish-water fish may act as the intermediate host of the parasite. The most simple and convenient method of diagnosing capillariasis is stool examination. Two cases were diagnosed by histology.Mebendazole or albendezole 200 mg orally twice a day for 20-30 d is the treatment of choice. All the patients were cured, and relapses were not observed within 12 mo.

    Full Text Available ABSTRACT: Chikungunya virus is no stranger to the Indian sub- continent. Since its first isolation in Calcutta [1] in 1963, there have been several reports of chikung unya virus infection in different parts of India [2], [3], [4]. The last outbreak of chikungunya virus infection o ccurred in India in 1971. Subsequently there has been no activ e or passive surveillance carried out in the country and therefore, it ‘seemed’ that the virus h ad ‘disappeared’ from the subcontinent [5] However, recent reports of large scale outbreaks of fever caused by chikungunya virus infection in several parts of Southern India have confirmed th e re-emergence of this virus. It has been estimated that over 1,80,000 cases have occurred in India since December 2005 [6] Andhra Pradesh (AP was the first state to report this dise ase in December 2005, and one of the worst affected (over 80,000 suspected cases . Over 12% of patients who contract chikungunya virus infection develop chronic joint symptoms [7] . OBJECTIVE: To test the efficacy of chloroquine in reducing the pain of chikungunya induced arthritis a s compared to paracetamol. METHODOLOGY: A Randomized Clinical Trial was carried out in a c ommunity attached to urban health centre of PESIMSR, Kuppam during August 2006. Among the 132 cases of arthritis, 86 persons were selected based on their availability and consent to participate. They were divided into two randomly assigned groups namely Cat egory–1(Chloroquine group and Category–2 ( Paracetamol group. Chloroquine tablet -155 mg and Paracetamol tablet - 500 mg were administered as a single dose to the two groups respectively. The groups were followed up for 8 days and the results were analyzed. STATISTICAL ANALYSIS: Analysis was carried out by using S.P.S.S. package. Asymptoic test statistic an d X 2 MH (Chi square test were used to evaluate the effect of the drugs.

    Full Text Available Background: Human immunodeficiency virus (HIV-positive adolescents by virtue of their position are prone to dangerous behaviors including risk-taking for HIV transmission. Objective: To determine the awareness of HIV status and risk factors for HIV transmission among HIV-positive adolescents, and how these impact their behavior. Materials and Methods: A case study approach was used to study a random sample of 400 HIV-positive adolescent children attending an antiretroviral (ART clinic in Kano, Kano State, Nigeria. Data were analyzed using Statistical Package for the Social Sciences (SPSS 16.0 computer statistical software. Result: The mean age of the adolescents was 14.9 ± 3.15 years. The majority were females (54.8% from a polygamous family (57.5%. About two-thirds or 251 (62.8% patients knew their HIV status. The age of 14 years and above (z = 11.36, P = 0.0001 and having at least secondary school level of education (z = 2.78, P = 0.005 were significantly associated with awareness of HIV status on binary logistic regression. Up to 311 (77.8% patients had good awareness of the risks of HIV transmission. Awareness of risk of HIV transmission was associated with awareness of HIV status (X 2 = 166.2, P = 0.0001. There was a significant variation in the behaviors between those who were aware of their HIV status and those who were not. Paradoxically, the percentage differences in risk-taking were remarkably high in all the variables examined, and were all in the direction of the adolescents who had good knowledge of the risk factors for HIV transmission. Conclusion and Recommendation: Health ministries, development partners working in this field, and behavioral change communication experts should develop formidable strategies for addressing this menace. There is also a dire need for further research in this area.

    This study examined how volume in certain patient case types and breadth across patient case types in the outpatient clinic setting are related to Neurology Clerkship student performance. Case logs from the outpatient clinic experience of 486 students from The University of Chicago Pritzker School of Medicine, USA, participating in the 4week Neurology Clerkship from July 2008 to June 2013 were reviewed. A total of 12,381 patient encounters were logged and then classified into 13 diagnostic categories. How volume of cases within categories and the breadth of cases across categories relate to the National Board of Medical Examiners Clinical Subject Examination for Neurology and a Neurology Clerkship Objective Structured Clinical Examination was analyzed. Volume of cases was significantly correlated with the National Board of Medical Examiners Clinical Subject Examination for Neurology (r=.290, pNeurology (r=.231, p=.017), however was not significantly correlated with any component of the Objective Structured Clinical Examination. Volume of cases correlated with higher performance on measures of specialty knowledge and clinical skill. Fewer relationships emerged correlating breadth of cases and performance on the same measures. This study provides guidance to educators who must decide how much emphasis to place on volume versus breadth of cases in outpatient clinic learning experiences. Copyright © 2016 Elsevier Ltd.

    Full Text Available Rabies remains endemic in Ghana and continues to pose a major public health threat to humans and animals with nearly hundred percent (100% case fatality rate in humans. We report of a presumptive case of human rabies whose survival was a rare occurrence in rural Ghana. Lessons from this case study provides a critically needed focus in helping improve rabies surveillance and case management in Ghana. We report of the survival of a 36 year old man who developed clinical rabies three weeks after he was bitten by his dog while restraining the dog with a chain. Prior to this he did not observe any abnormal or rabid behaviour in the dog. Following the bite, he did not immediately resort to hospital treatment, but rather to traditional application of herbs to the laceration he sustained after the bite. Reason given for not seeking immediate hospital treatment was that the dog was not rabid and lack of funds to seek hospital care. However, he began to show symptoms consistent with rabies virus infection after 10 days and was subsequently rushed to the hospital by relatives. At the hospital, he was administered human immune tetanus immunoglobulin, diazepam, ceftriaxone, paracetamol and intravenous fluids. No rabies vaccine was administered. Six days after commencing treatment patient became well, showed no signs of confused state of mind, hydrophobia nor photophobia. He was discharged home after 13 days of commencing treatment. This study provides insight on a presumptive case of Human rabies case that survived despite non-administration of rabies vaccine during esposure. It also exposes the weaknesses in the health and veterinary systems in rural Ghana regarding rabies surveillance and case management.

    This study is a parasitological and clinical study on human scabies. This study was carried out on 100 patients attending the Dermatology Outpatient Clinic at Ain Shams University Hospitals, including 54 males and 46 females. All patients were subjected to detailed history taking, complete dermatological examination including Skin Scraping Test and Burrow Ink Test. Younger patients attended the dermatology clinic earlier than older patients, who usually delayed their visits until complications occurred. Scratching, erythematous papules and secondary infected lesions were the commonest lesions. The hands, wrist and external genitalia were the most frequently affected sites while the feet, ankles, knees and back were the least affected. Burrows could only be detected in 40% of patients. The most frequent sites were the web spaces, external genitalia, and finger sides. Burrow Ink Test was positive among 85% of patients with burrows while mites could be identified by Skin Scraping Test in 55% of patients. The most frequent clinical manifestations in the parasitologically positive patients were itching, burrows, and papules, and the most frequent sites were the web spaces, and the finger sides. Multiple sites affection was the characteristic feature among the preschool age children who represented 14% of cases.

    Phase I clinical trials generally raise greater ethical and human protection challenges than later stage clinical trials, suggesting a need to proceed cautiously. This is particularly the case for Phase I trials with a novel therapy being tested in humans for the first time, usually termed first-in-human (FIH) trials. In January 2009, the Food and Drug Administration approved the Investigational New Drug application of Geron Corporation, a small California-based biopharmaceutical company, to initiate a clinical trial to assess GRNOPC1, a human embryonic stem cell-derived candidate therapy for severe spinal cord injuries. This article evaluates the ethical and human subject protection issues raised by the Geron FIH trial. It identifies problems with the approval process and with the conduct of the trial, and then recommends ways to improve review of future proposed trials with novel and high-risk therapies.

    Full Text Available The authors report the clinical, laboratorial and epidemiological aspects of a human case of jungle yellow fever. The patient suffered from fever, chills, sweating, headaches, backaches, myalgia, epigastric pains, nausea, vomiting, diarrhea and prostration. He was unvaccinated and had been working in areas where cases of jungle yellow fever had been confirmed. Investigations concerning the yellow fever virus were performed. Blood samples were collected on several days in the course of the illness. Three of these samples (those obtained on days 5,7 and 10 were inoculated into suckling mice in attempt to isolate virus and to titrate the viremia level. Serological surveys were carried out by using the IgM Antibodies Capture Enzyme Linked Immunosorbent Assay (MAC-ELISA, Complement Fixation (CF, Hemagglulinalion Inhibition (HI and Neutralization (N tests. The yellow fever virus, recovered from the two first samples and the virus titration, showed high level of viremia. After that, specific antibodies appeared in all samples. The interval between the end of the viremia and the appearance of the antibodies was associated with the worsening of clinical symptoms, including bleeding of the mucous membrane.

    Cytomegalovirus (CMV) retinitis has been extensively described in patients with advanced or late human immunodeficiency virus (HIV) disease under ineffective treatment of opportunistic infection and antiretroviral therapy (ART) failure. However, there is limited information about patients who develop active cytomegalovirus retinitis as an immune reconstitution inflammatory syndrome (IRIS) after successful initiation of ART. Therefore, a case definition of cytomegalovirus-immune recovery retinitis (CMV-IRR) is proposed here. We reviewed medical records of 116 HIV-infected patients with CMV retinitis attending our institution during January 2003-June 2012. We retrospectively studied HIV-infected patients who had CMV retinitis on ART initiation or during the subsequent 6 months. Clinical and immunological characteristics of patients with active CMV retinitis were described. Of the 75 patients under successful ART included in the study, 20 had improvement of CMV retinitis. The remaining 55 patients experienced CMV-IRR; 35 of those developed CMV-IRR after ART initiation (unmasking CMV-IRR) and 20 experienced paradoxical clinical worsening of retinitis (paradoxical CMV-IRR). Nineteen patients with CMV-IRR had a CD4 count of ≥50 cells/µL. Six patients with CMV-IRR subsequently developed immune recovery uveitis. There is no case definition for CMV-IRR, although this condition is likely to occur after successful initiation of ART, even in patients with high CD4 T-cell counts. By consequence, we propose the case definitions for paradoxical and unmasking CMV-IRR. We recommend close follow-up of HIV-infected patients following ART initiation. © The Author 2014.

    Placebos are arguably the most commonly prescribed drug, across cultures and throughout history. Nevertheless, today many would consider their use in the clinic unethical, since placebo treatment involves deception and the violation of patients' autonomy. We examine the placebo's definition and its clinical efficacy from a biopsychosocial perspective, and argue that the intentional use of the placebo and placebo effect, in certain circumstances and under several conditions, may be morally acceptable. We highlight the role of a virtue-based ethical orientation and its implications for the beneficent use of the placebo. In addition, the definitions of lying and deception are discussed, clarified and applied to the clinical placebo dilemma. Lastly, we suggest that concerns about patient autonomy, when invoked as a further argument against administering placebos, are extended beyond their reasonable and coherent application.

  6. Congenital dislocation of the patella - clinical case

    Pedro Miguel Sá

    2016-02-01

    Full Text Available ABSTRACT Congenital patellar dislocation is a rare condition in which the patella is permanently dislocated and cannot be reduced manually. The patella develops normally as a sesamoid bone of the femur. This congenital dislocation results from failure of the internal rotation of the myotome that forms the femur, quadriceps muscle and extensor apparatus. It usually manifests immediately after birth, although in some rare cases, the diagnosis may be delayed until adolescence or adulthood. Early diagnosis is important, thereby allowing surgical correction and avoiding late sequelae, including early degenerative changes in the knee. A case of permanent dislocation of the patella is presented here, in a female child aged seven years.

    SUMMARY The osteonecrosis of the maxillares caused by bisphosphonates (OMB) either wrongly known or not reconised in earlier times became nowadays very important among the dentists and maxillo-facials surgeons because of the potential serious consequences that might bring in the oral cave of the patients, who are suffering already for their base condition. The goal of our work was to verify if a deep treatment and an attentive observation with a close follow-up can bring to the resolution of serious cases of ostenecrosis of the maxillares by bisphosphonantes. Although without a statistic value our case report put the basis for a chance to execute wider casistic studies. PMID:23285372

    Long term therapies needed for managing human cytomegalovirus (HCMV) infections in immunosupressed patients provided the background for the emergence of the resistance to antivirals active against HCMV. In addition, laboratory selected mutants have also been readily achieved. Both clinical and laboratory resistant strains share the same determinants of resistance. Ganciclovir resistance may be due to a few mutations in the HCMV UL97 gene and/or viral DNA pol gene, the former being responsible for about 70% of clinical resistant isolates. Among them, V464, V594, S595 and F595 are the most frequent mutations. Because of their less extensive clinical use, much less is known about resistance to foscarnet and cidofovir (formerly, HPMPC) but in both cases, it has been associated to mutations in the DNA pol. Ganciclovir resistant strains showing DNA pol mutations are cross-resistant to cidofovir and their corresponding IC50 are normally higher than those from strains harboring only mutations at the UL97 gene. To date, foscarnet resistance seems to be independent of both ganciclovir and cidofovir resistance.

Methods A retrospective analysis was performed on clinical features, laboratory findings, imaging profiles, treatment and outcomes of 22 patients with HE who were admitted to our hospital between June 2010 and September 2013.  Results Clinical symptoms were mainly acute or subacute cognitive impairment (9 cases, psychiatric symptoms (6 cases, seizures (5 cases, ataxia (5 cases, stroke-like episodes (6 cases, tremor (1 case, myoclonus (2 cases and disturbance of consciousness (3 cases. Marked increase was found in serum anti-thyroid peroxidase (anti-TPO antibody level (19 cases and anti-thyroglobulin (anti-TG antibody level (20 cases. Twenty-one cases were treated with glucocorticoids, and one patient was treated only with general neurotrophic therapy, such as ganglioside. Except for 4 cases showed bad response to steroids, the rest patients had an obvious improvement. Conclusions Hashimoto's encephalopathy is an encephalopathy with the presence of elevated antithyroid antibodies, and most patients showed good response to steroids. So early diagnosis and treatment is particularly important for improving prognosis. This disease should be considered as an important differential diagnosis for encephalopathy of unknown etiology, and screening for serum antithyroid antibodies should be performed as initial screening test. doi: 10.3969/j.issn.1672-6731.2014.07.008

  11. Knee osteoarthrosis secondary to ochronosis -clinical case,

    2014-12-01

    Full Text Available Alkaptonuria is a rare metabolic disease in which a deficiency of the enzyme homogentisate dioxygenase causes an accumulation of homogentisic acid. Ochronosis consists of excessive deposition of homogentisic acid in the connective tissue and presents as a chestnut brown or black pigmentation. With aging, the accumulation of pigments from homogentisic acid in the joints causes osteoarthrosis. There is no specific treatment for the disease and the approach is symptomatic. Arthroplasty is the solution for severe cases of osteoarthrosis caused by this pathological condition and presents results comparable to those from patients with primary osteoarthrosis. Here, the case of a 67-year-old patient who underwent several arthroplasty procedures because of osteoarthrosis caused by this rare pathological condition is presented. The last surgical intervention consisted of total right knee arthroplasty.

    The integration of evidence into reflective health care practice has been on the rise in recent years and is a phenomenon that has affected all health care professions, including massage therapy. Clinical case studies are a research design that follows one patient or subject, making the studies ideal for use in clinical practice. They are valuable for communicating information from clinical practice to the broader community. Case studies have face validity that may be more valuable to individual practitioners than homogeneous randomized controlled trials, as the practitioner may recognize a complex patient in the case report. At Humber College, Student Massage Therapists (SMTs) create, conduct, and communicate results of a clinical case study prior to graduation. This article describes the process and experience.

    The authors report a case of a patient with a prior history of alcohol abuse who developed nodules and ulcerated skin lesions on his trunk and lower extremities along the line of the lymphatic draining area. The patient's X-ray showed reticular nodular intersticial infiltrates at the lung bases. There was a positive culture of supraclavicular lymph node for Sporothrix schenckii. After specific treatment using mainly potassium iodide, there was regression of cutaneous lesions and lung infiltrates. The authors present a discussion on the deseases' forms of presentation, highlighting the lung involvement ans further discuss the diagnosis and treatment of sporotrichosis.

    Fusion is defined as the partial or complete union of two or more teeth during their development; it can occur between normal teeth or between a normal tooth and a supernumerary tooth. This anomaly can be unilateral or bilateral and can affect any teeth, although deciduous teeth are more frequently damaged. It can also affect the patient’s appearance, cause changes in the dental arch space, lead to cavities and affect periodontal structures. This article presents the case of 13-year-old who c...

    The authors report a case of liposarcoma in the sub-mandibular region, and they describe the histological species and the way of spreading. They suggest a surgical, non-demolitional therapy, that they carried radical if it is related to a strict follow-up. Anatomical and functional results, after demolishing surgical therapy, are sometimes unacceptable if the real benefits in terms of survival are considered. No supporting therapy has been used because of the presumed insensibility of the neoplasm to the chemo-radiotherapeutic treatments. At 2 years from surgical treatment no local relapses, on distance metastasis have been related.

    Full Text Available Introduction. Ehrlichiosis is a bacterial zoonosis transmitted by hematophagous arthropods - ticks. In humans, it occurs as monocytic, granulocytic, and ewingii ehrlichiosis. Pathological process is based on parasitic presence of Ehrlichia organisms within peripheral blood cells - monocytes and granulocytes. Case Outline. Fifty-two year old patient was admitted to hospital due to high fever of over 40°C that lasted two days, accompanied with chills, muscle aches, malaise, loss of appetite, headache, confusion, breathing difficulties, and mild dry cough. The history suggested tick bite that occurred seven days before the onset of disease. Doxycycline was introduced and administered for 14 days, causing the disease to subside. Indirect immunofluorescence assay was used to analyze three serum samples obtained from this patient for Ehrlichia chaffeensis antibodies, and peripheral blood smear was evaluated for the presence of Ehrlichia and Ehrlichia aggregation into morulae. Conclusion. Ehrlichiosis should be considered in each case where there is a history of tick bite together with the clinical picture (high fever, chills, muscle aches, headache, generalized weakness and malaise, and possible maculopapular rash. The presence of Ehrlichia chaffeensis antibodies was confirmed in a patient with the history of tick bite, appropriate clinical picture and indirect immunofluorescence assay. This confirmed the presence of human monocytotropic ehrlichiosis, a disease that is uncommonly identified in our country.

  19. Human Defensins: Potential Tools for Clinical Applications

    2012-02-01

    Full Text Available As components of the innate immune system, antimicrobial peptides in the form of human defensins play an important role in host defense by serving as the epithelial layer’s biochemical barrier against local infections. Recent studies have shown these molecules to have far more additional cellular functions besides their antimicrobial activity. Defensins play a role in cell division, attraction and maturation of immune cells, differentiation and reorganization of epithelial tissues, wound healing and tumor suppression. This multitude of function makes human defensins appear to be excellent tools for therapeutic approaches. These antimicrobial peptides may be used directly as a remedy against bacterial and viral infections. Furthermore, the application of human defensins can be used to promote wound healing and epithelial reorganization. In particular, human β-defensins have a strong impact on osteoblast proliferation and differentiation. Human β-defensins have already been applied as a vaccination against HIV-1. Another potentially useful characteristic of defensins is their suitability as diagnostic markers in cancer therapy. In particular, α-defensins have already been used for this purpose. Human α-defensin-3, for example, has been described as a tumor marker for lymphocytes. High gene expression levels of α-defensin-3 and -4 have been detected in benign oral neoplasia, α-defensin-6 is considered to be a tumor marker for colon cancer.

    2010-07-01

    Optimal medical care is critically dependent on clinicians' skills to make the right diagnosis and to recommend the most appropriate therapy, and acquiring such reasoning skills is a key requirement at every level of medical education. Teaching clinical reasoning is grounded in several fundamental principles of educational theory. Adult learning theory posits that learning is best accomplished by repeated, deliberate exposure to real cases, that case examples should be selected for their reflection of multiple aspects of clinical reasoning, and that the participation of a coach augments the value of an educational experience. The theory proposes that memory of clinical medicine and clinical reasoning strategies is enhanced when errors in information, judgment, and reasoning are immediately pointed out and discussed. Rather than using cases artificially constructed from memory, real cases are greatly preferred because they often reflect the false leads, the polymorphisms of actual clinical material, and the misleading test results encountered in everyday practice. These concepts foster the teaching and learning of the diagnostic process, the complex trade-offs between the benefits and risks of diagnostic tests and treatments, and cognitive errors in clinical reasoning. The teaching of clinical reasoning need not and should not be delayed until students gain a full understanding of anatomy and pathophysiology. Concepts such as hypothesis generation, pattern recognition, context formulation, diagnostic test interpretation, differential diagnosis, and diagnostic verification provide both the language and the methods of clinical problem solving. Expertise is attainable even though the precise mechanisms of achieving it are not known.

    The port of Rotterdam, The Netherlands, is the world's largest container port. In 2006, one of these containers caused a chemical incident. Methylbromide is used in some countries as a pesticide for the fumigation of maritime containers. Because of an insufficiently performed detoxification, this insecticide intoxicated several employees and some of the ambulance crew and Mobile Medical Team (MMT). The victims displayed symptoms of sore throat, irritated eyes, and hypersalivation. One of the victims suffered from multiple epileptic seizures. Two victims were admitted to the intensive care unit for respiratory support. Three other employees showed milder symptoms and received supportive care but were not admitted to the hospital. This complicated case shows that the safety of the ambulance crew and MMT must be guaranteed. It also demonstrates that healthcare providers cannot always oversee the accident scene and that there are some pitfalls that are almost impossible to prevent.

    Epilepsy is a serious health disorder affecting both paediatric and adult population worldwide. Due to difficulties in identifying its aetiology, initial management is often guided by empiric therapy measures. Symptomatic control requires the use of antiepileptic drugs (AEDs), many of which have the potential for adverse drug interactions. Children are especially susceptible to drug interactions and frequently exhibit atypical adverse events, which may require special care. Aim. To demonstrate a case of a 15 year old girl suffering from refractory epilepsy with underlying focal cortical dysplasia (FCD), whose seizure deterioration was most probably associated with drug-drug interactions between prescribed common antiepileptic drugs, namely valproic acid, phenobarbital or the prodrug primidon and carbamazepine.

    Full Text Available The mucopolysaccharidoses (MPS are a heterogeneous group of inborn errors of lysosomal glycosaminoglycan (GAG metabolism. The importance of this group of disorders among the inborn errors of metabolism led us to report 19 cases. METHOD: We performed clinical, radiological, and biochemical evaluations of the suspected patients, which allowed us to establish a definite diagnosis in 19 cases. RESULTS: Not all patients showed increased GAG levels in urine; enzyme assays should be performed in all cases with strong clinical suspicion. The diagnosis was made on average at the age of 48 months, and the 19 MPS cases, after a full clinical, radiological, and biochemical study, were classified as follows: Hurler -- MPS I (1 case; Hunter -- MPS II (2 cases; Sanfilippo -- MPS III (2 cases; Morquio -- MPS IV (4 cases; Maroteaux-Lamy -- MPS VI (9 cases; and Sly -- MPS VII (1 case. DISCUSSION: The high relative frequency of Maroteaux-Lamy disease contrasts with most reports in the literature and could express a population variability.

    The search for the identification of the sensory apparatus encoding muscle pain sensation in humans is recounted. Basic neurophysiologic animal studies, leading to a description of slowly conducting afferent from muscle and definition of high threshold polymodal muscle nociceptors, and pioneer psychophysic human studies together with recent microneurographic experiments in humans are described. The phenomena of muscle pain broad localization and distant referral are discussed, and clinical implications are extrapolated to interpret muscle pain as a localizing sign of mononeuropathy or radiculopathy. The identification of human muscle nociceptors has defined the scientific standard to test emerging clinical descriptions having muscle pain as a symptom.

    Full Text Available Introduction. The number of humans infected by Fasciola hepatica is increasing worldwide. Humans can become accidental hosts by ingesting drinking water or plants contaminated with metacercariae. Case report. We reported a case of a 68-year-old Serbian woman, in which the diagnosis of acute fasciolosis had been established after serious diagnostic concerns. Based on clinical picture (episodic right upper quadrant abdominal pain, febrility and generalized body pain and biochemical analyses (high eosinophilia and high activity of alkaline phosphatase, she was appointed as suspected to the acute fasciolosis. Stool and duodenal aspirate exams were negative for Fasciola ova. In the absence of adequate serologic diagnostic for fasciolosis in Serbia, the diagnosis was confirmed using enzyme immunoassays and immunoblot at the Institute for Tropical Diseases in Hamburg, Germany. Soon after triclabendazole was administered, the symptoms disappeared and biochemical values returned to normal. Conclusion. The diagnosis of human fasciolosis may be problematic and delayed, especially in non endemic areas, because physicians rarely encounter this disease and a long list of other diseases must be considered in the differential diagnosis. The syndrome of eosinophilia, fever, and right upper quadrant abdominal pain suggest acute fasciolosis. Unclear source does not rule out fasciolosis.

    Full Text Available OBJECTIVE: Understand the behavior, functional repercussion and relationship with epidemiological factors of asteroid hyalosis (AH and retrospective observational case series. METHODS: Fifty-eight patients diagnosed with AH (24 women and 34 men were studied. All patients were submitted to a thorough ophthalmological examination. RESULTS: We observed a statistical association between the presence of AH and male sex (p=0,042. An increase in prevalence of this pathology was observed with increasing age. We determined an odds ration of 5,24 of a patient over 50 years old having AH, when compared to patients bellow this threshold. Eighty-six percent of patients had unilateral vitreous deposits. We measured a lower IOP in the affected eye, with the difference being in average 2,68 ± 1,45 mmHg (p=0,037. We observed no statistical association between AH and age related macular degeneration, diabetes or glaucoma. Five eyes were submitted to facoemulsification combined with pars plana vitrectomy with an average gain of 7 lines (Snellen in visual acuity (p=0,03. CONCLUSION: In our sample a clear association between AH, ageing and male sex was observed. The majority of patients had unilateral vitreous deposits. Vitrectomy in association with facoemulsification is a safe and effective intervention in this group of patients.

Methods  The clinical characteristics of 9 patients with anti-NMDAR encephalitis in Department of Neurology, Army General Hospital of Chinese PLA from October 2013 to October 2015, were retrospectively analyzed. And by literatures review, the pathogenesis, clinical feature, diagnosis, treatments and prognosis of this disease were summarized. Results  The average age of the 9 patients (3 men and 6 women was 39 years, 5 of them had precursor nonspecific infection. The initial symptom of neurologic system was mental-behavior disorder in all the 6 females, or epilepsy in all the 3 males. Mental-behavior disorder existed in all the 9 cases during the disease course, including 7 cases of epilepsy, 8 cases of consciousness disturbance, 5 cases of involuntary movement, and 3 cases of inadequate ventilation. The anti-NMDAR antibodies were positively detected from the cerebrospinal fluid and blood of all the 9 cases. After gamma globulin and hormone therapy, 8 cases were cured or better, and only 1 case invalid. A six months follow-up found that 8 cases were independent with eusemia and 1 case got disability. Conclusions  The clinical characteristics of anti-NMDAR encephalitis are mental-behavior disorder, or epilepsy upon the basis of a precursor infection, with positive anti-NMDAR antibodies detected from the cerebrospinal fluid and blood. Gamma globulin and hormone therapy may help th e clinical recovery. DOI: 10.11855/j.issn.0577-7402.2016.09.13

    Full Text Available Abstract Background The use of tolerogenic DCs is a promising therapeutic strategy for transplantation and autoimmune disorders. Immunomodulatory DCs are primarily generated from monocytes (MDDCs for in vitro experiments following protocols that fail to fulfil the strict regulatory rules of clinically applicable products. Here, we compared the efficacy of three different tolerance-inducing agents, dexamethasone, rapamycin and vitamin D3, on DC biology using GMP (Good Manufacturing Practice or clinical grade reagents with the aim of defining their use for human cell therapy. Methods Tolerogenic MDDCs were generated by adding tolerogenic agents prior to the induction of maturation using TNF-α, IL-β and PGE2. We evaluated the effects of each agent on viability, efficiency of differentiation, phenotype, cytokine secretion and stability, the stimulatory capacity of tol-DCs and the T-cell profiles induced. Results Differences relevant to therapeutic applicability were observed with the cellular products that were obtained. VitD3-induced tol-DCs exhibited a slightly reduced viability and yield compared to Dexa-and Rapa-tol-DCs. Phenotypically, while Dexa-and VitD3-tol-DCs were similar to immature DCs, Rapa-tol-DCs were not distinguishable from mature DCs. In addition, only Dexa-and moderately VitD3-tol-DCs exhibited IL-10 production. Interestingly, in all cases, the cytokine secretion profiles of tol-DCs were not modified by a subsequent TLR stimulation with LPS, indicating that all products had stable phenotypes. Functionally, clearly reduced alloantigen T cell proliferation was induced by tol-DCs obtained using any of these agent. Also, total interferon-gamma (IFN-γ secretion by T cells stimulated with allogeneic tol-DCs was reduced in all three cases, but only T cells co-cultured with Rapa-tol-DCs showed impaired intracellular IFN-γ production. In addition, Rapa-DCs promoted CD4+ CD127 low/negative CD25high and Foxp3+ T cells. Conclusions Our

    2016-09-01

    Full Text Available Pulmonary arteriovenous fistula (PAVF is abnormally dilated vessels that provide a right-to-left shunt between pulmonary artery and pulmonary vein and is clinically divided into simple and complex type. Here, we report four cases of surgically resected sporadic PAVFs presenting various clinical and histologic spectrums. Cases 1 (a 57-old-female and 2 (a 54-old-female presented as incidentally identified single aneurysmal fistulas and the lesions were surgically removed without complication. On the other hand, case 3 (an 11-old-male showed diffuse dilated vascular sacs involving both lungs and caused severe hemodynamic and pulmonary dysfunction. Embolization and surgical resection of the main lesion failed to relieve the symptoms. Case 4 (a 36-old-male had a localized multiloculated cyst clinically mimicking congenital cystic adenomatoid malformation. Microscopically, the lesion consisted of dilated thick vessels, consistent with the diagnosis of fistulous arteriovenous malformation/hemangioma.

(2 To find out the various fungi causing pulmonary mycoses in clinically suspected pulmonary tuberculosis cases. Methods: 200 clinically suspected pulmonary tuberculosis cases who visited the department of microbiology for the diagnostic microscopic examination of sputum sample for acid fast bacilli were included in this cross sectional study, carried out under the department of microbiology, Sikkim Manipal institute of medical sciences, over one year. Smears of sputum samples were examined microscopically for acid fast bacilli and fungal elements. Sputum samples were also plated onto different fungal culture media. Results: Out of 200 patients, various types of pathogens were detected in 54 (27% patients. Fourteen (7% patients were positive only for AFB, while fungus as a primary etiological agent was detected in 16(8% patients. Fungus as a secondary etiological agent was detected in 4 (2% patients [AFB with fungus in 2 (1%, AFB with fungus and bacteria in 1 (0.5% and bacteria with fungus in 1 (0.5% patient]. Conclusion: Pulmonary mycosis can be a primary infection in non- tuberculosis cases or co-infection in pulmonary tuberculosis cases. Investigation for fungal cause in clinically suspected cases of pulmonary tuberculosis will prevent misdiagnosis and mistreatment of cases. [Int J Res Med Sci 2015; 3(1.000: 260-268

    Angelman syndrome is characterised by mental retardation, epilepsy, speech impairment, facial dysmorphism and a characteristic behavioural phenotype. Diagnostic clinical criteria have been defined by consensus since 1995. It is caused by deficiency or inactivation of the UB3A gene. There is a percentage of cases which satisfy these clinical features but have negative genetic testing. We consider it necessary to analyse the patient characteristics and possible phenotype-genotype correlations. All cases which were treated between 1981 and 2007 in a neurology unit and fulfilled the clinical criteria were included. Genetic diagnosis was made by methylation testing and fluorescent in situ hybridization. Thirteen patients were studied, nine with positive genetic testing and four with negative testing who completed the clinical criteria. The average age at diagnosis was 37 months. Eleven cases showed acquired microcephaly. Flat occiput, mouth and maxillary malformations, hypopigmentation, a happy appearance and hyperactivity were practically constant characteristics. Speech and walking ability were the areas which showed most deficit. Twelve cases had epilepsy. Three of the cases with normal genetic testing showed less microcephaly and better psychomotor development, particularly in walking ability. The phenotypical characteristics of the syndrome should be known before requesting specific genetic testing and to make a diagnosis even in cases with negative genetic. The phenotype characteristics that describe Angelman syndrome were verified. Deletion cases had a worse outcome.

    2016-01-01

    Introduction: Campylobacters are the most frequently identified bacteria causing diarrhoea in humans worldwide. Campylobacter lanienae was isolated for the first time in 2000 from faecal samples of two asymptomatic abattoir workers in Switzerland during a routine hygiene screen, but has never been associated with human disease. Case presentation: At hospital admission, the patient reported diarrhoea, lower abdominal cramps, nausea, one episode of bilious vomiting and low-grade fever of 38 °C. The patient was having 10 or more diarrheic stools per day as well as during the night, and had noticed blood mixed with the stools on several occasions. Stool cultures were negative for species of Salmonella and Shigella, Escherichia coli O157:H7 and Yersinia enterocolitica, but were positive for C. lanienae. Identification was made by classical biochemical testing, as well as 16S rRNA gene and cpn60 sequencing. The patient slowly improved without antibiotic treatment and was discharged nine days after admission with complete resolution of symptoms. Conclusion: On the whole it seems very likely that C. lanienae was the causative agent. Clinical microbiologists should be aware of this micro-organism which can be identified by phenotypic and molecular methods. The real burden of C. lanienae infection in humans might be underestimated and should be further investigated as a potential cause of human diarrhoea disease.

    With the advent of antibiotic resistance, pathogenic bacteria have become a major threat in cases of neonatal sepsis; however, guidelines for treatment have not yet been standardized. In this study, 15 cases of neonatal Streptococcus agalactiae sepsis from our hospital were retrospectively analyzed. Of these, nine cases showed early-onset and six cases showed late-onset sepsis. Pathogens were characterized by genotyping and antibiotic sensitivity tests on blood cultures. Results demonstrated that in cases with early-onset sepsis, clinical manifestations affected mainly the respiratory tract, while late-onset sepsis was accompanied by intracranial infection. Therefore, we suggest including a cerebrospinal fluid examination when diagnosing neonatal sepsis. Bacterial genotyping indicated the bacteria were mainly type Ib, Ia, and III S. agalactiae. We recommend treatment with penicillin or ampicillin, since bacteria were resistant to clindamycin and tetracycline. In conclusion, our results provide valuable information for the clinical treatment of S. agalactiae sepsis in neonatal infants.

    A proposal by the American Society for Bioethics and Humanities (ASBH) to identify individuals who are qualified to perform ethics consultations neglects case complexity in candidates' portfolios. To protect patients and healthcare organizations, and to be fair to candidates, a minimum case complexity level must be clearly and publicly articulated. This proof-of-concept study supports the feasibility of assessing case complexity. Using text analytics, we developed a complexity scoring system, and retrospectively analyzed more than 500 ethics summaries of consults performed at an academic medical center during 2013. We demonstrate its use with seven case summaries that range in complexity from uncomplicated to very complicated. We encourage the ASBH to require a minimum level of case complexity, and recommend that attestation portfolios include several cases of moderate complexity and at least one very complex case.

    Deviations from the normal of alpha-fetoprotein (AFP) concentrations in fetal serum, amniotic fluid, maternal serum and adult human serum can be explained by understanding the normal physiology and the pathophysiology of AFP synthesis and metabolism. AFP is the prototype of oncofetal markers. Emphasis is given to the usefulness of elevated serum AFP levels in the diagnosis and management of primary hepatomas and tumors of germ cell origin. The ability to detect neural tube defects early in gestation by monitoring maternal serum and amniotic fluid AFP concentrations is discussed.

    Clinical trials increasingly rely upon web-based Clinical Trials Management Systems (CTMS). As with clinical care systems, Human Computer Interaction (HCI) issues can greatly affect the usefulness of such systems. Evaluation of the user interface of one web-based CTMS revealed a number of potential human-computer interaction problems, in particular, increased workflow complexity associated with a web application delivery model and potential usability problems resulting from the use of ambiguous icons. Because these design features are shared by a large fraction of current CTMS, the implications extend beyond this individual system.

    We report the results of clinical and electrophysiological examinations in 131 cases of meralgia paresthetica (MP) among 120 unselected patients, 69 men and 51 women, aged 15-81 years. All patients experienced permanent or intermittent pain, and all but one had permanent sensory impairment of the thigh. The lateral aspect of the thigh was solely involved in 88 cases and the anterior aspect was also or exclusively involved in 32 cases. The right thigh was involved 62 times and the left 58 times. Symptom duration varied from 2 weeks to 20 years. The initial diagnosis was meralgia paresthetica in 47 cases (39%), root disease in 35 cases, and osteoarthritis in 6 cases; no diagnosis was proposed in the 32 remaining cases. Two cases had undergone previous spine surgery for disk herniation, with no benefit. A precise cause could explain the lateral femoral cutaneous nerve (LFCN) lesion in 46 cases, the other 74 cases being considered idiopathic (25% of patients were obese). Only one case required surgery to relieve symptoms. LFCN conduction was studied orthodromically, distally from the anterior superior iliac spine. The side-to-side amplitude ratio (ssRatio) was greater than 2.3 in 118 of 120 patients (98.3%) and was a better index to confirm a lesion of the LFCN than SNAP amplitude, which was abnormal (less than 3 microV) in 88 cases (73.3%). Only two of the 11 bilateral cases had an ssRatio lower than 2.3 (they were both 2.0). An ssRatio of 2.3 or more and a SNAP amplitude lower than 3 microV provided a specificity of 98.75% or more. The mean axonal loss was 88%. These clinical and electrophysiological data highlight the central role the neurophysiologist should play in diagnosing MP by means of an LFCN conduction study.

    Cytologic and bacteriologic investigations were carried out with a total of 364 samples of cow milk and secretion from 11 farms taken from individual quarters of the udder that have reacted positively and strongly positively with the rapid mastitis test Bernburg. It was found that in 330 of the cases there were data of clinical and subclinical mastitis of varying etiology. In 43 of the cases the causative agent (as isolated in pure cultures) proved to be "D" streptococci, giving positive reaction as judged by Schermann's criteria--from 9 cases of clinical and 34 cases of subclinical mastitis. The cell count varied from 360 000 to more than 5 million per cub. cm. Detailed studies were carried out on the cultural and biochemical properties of 31 strains of "D" streptococci, 17 strains belonging to Str. faecalis var. zymogenes, 9 strains--to Str. faecalis var. faecalis, and 5 strains--to Str. faecalis var. liquefaciens.

    Schizencephaly is an uncommon structural disorder of cerebral cortical development, characterized by congenital clefts spanning the cerebral hemispheres from the pial surface to the lateral ventricles and lined by cortical gray matter. Either an antenatal environmental incident or a genetic origin could be responsible for this lesion which occurs between the third and fourth month of gestation. We report the clinical and cranial imaging features of 30 children, of whom 15 had unilateral and 15 had bilateral lesions. Their ages at the time of the first presentation ranged from 1 month to 10 years. They were thoroughly studied from clinical, epileptical, imaging and electroencephalographic (EEG) viewpoints. Five patients were investigated by cranial computed tomography (CT), eight by cranial magnetic resonance (MR) imaging, and 17 by both methods. The clinical features consisted of mild hemiparesis in 17 cases (57%), 12/17 were related to a unilateral phenotype (80% of all unilateral forms) and 5/17 to a bilateral phenotype. A tetraparesis was present in nine cases, all of which were due to a bilateral cleft. Bilateral forms were significantly associated with tetraparesis, whereas unilateral forms were associated with hemiparesis. Mental retardation was observed in 17 cases (57%), and was observed significantly more often in bilateral clefts (80%). When both hemispheres are involved, an absence of reorganization of the brain function between the two hemispheres leads to severe mental deficits, in addition to the cerebral anomaly itself. Eleven patients had seizures (seven from unilateral and three from bilateral forms). The degree of malformation was not related to the severity of epilepsy. Migration disorders, such as dysplasia or heterotopia, were observed in 30% of cases and are also important etiopathogenetic factors. The septum pellucidum was absent in 13 cases (43%), with septo-optical dysplasia in two cases. Corpus callosum dysgenesis was noted in 30% of cases

    Metabolomics is a research field concerned with the analysis of metabolome, the complete set of metabolites in a given cell, tissue, or biological sample. Being able to provide a molecular snapshot of biological systems, metabolomics has emerged as a functional methodology in a wide range of research areas such as toxicology, pharmacology, food technology, nutrition, microbial biotechnology, systems biology, and plant biotechnology. In this review, we emphasize the applications of metabolomics in investigating the human breast milk (HBM) metabolome. HBM is the recommended source of nutrition for infants since it contains the optimal balance of nutrients for developing babies, and it provides a range of benefits for growth, immunity, and development. The molecular mechanisms beyond the inter- and intra-variability of HBM that make its composition unique are yet to be well-characterized. Although still in its infancy, the study of HBM metabolome has already proven itself to be of great value in providing insights into this biochemical variability in relation to mother phenotype, diet, disease, and lifestyle. The results of these investigations lay the foundation for further developments useful to identify normal and aberrant biochemical changes as well as to develop strategies to promote healthy infant feeding practices.

  13. Physiopathology of human embryonic implantation: clinical incidences.

    2010-01-01

    Full Text Available Embryo implantation consists of a series of events promoting the invasion of the endometrium and then the uterine arterial system by the extra-embryonic trophoblast. In order for this semi-heterologous implantation to succeed, the endometrium has to first undergo a number of structural and biochemical changes (decidualization. The decidua's various constituents subsequently play a role in the embryonic implantation. The third step is the transformation of the uterine vascular system and the growth of the placenta, which will provide the foetoplacental unit with nutrients. Several physiopathological aspects will be discussed: 1 the implantation window, regulated by maternal and embryonic hormonal secretions and thus influenced by any defects in the latter: dysharmonic luteal phase, 21-hydroxylase block, abnormal integrin expression, 2 the successive trophoblast invasions of uterine vessels which, when defective, lead to early embryo loss or late-onset vascular pathologies, as preeclampsia, 3 the pregnancy's immunological equilibrium, with a spontaneously tolerated semi-allogeneic implant, 4 the impact of pro-coagulant factors (thrombophilia on the pregnancy's progression, 5 the environment of the uterus, ranging from hydrosalpinx to uterine contractions. In summary, the least anatomical or physiological perturbation can interfere with human embryonic implantation - a very particular phenomenon and a true biological paradox.

    Raoultella ornithinolytica is a rare pathogen in human infection and bacteremic cases had been scarcely reported. For further comprehension of the rare infection, we summarized clinical characteristics of 6 cases that were detected at our medical facility and 5 cases from previous literature. The most common infectious focus was biliary infection and elderly patients with a history of any biliary intervention or malignancy were considered to be at a great risk for the infection. The prognosis of the patients was quite satisfactory. Bacterial identification in this report was performed on the basis of biochemical tests alone, and further investigations by molecular analysis are required to confirm our findings.

    2001-01-01

    Full Text Available INTRODUCTION: Friedreich's ataxia is a neurodegenerative disorder whose clinical diagnostic criteria for typical cases basically include: a early age of onset (< 20 or 25 years, b autosomal recessive inheritance, c progressive ataxia of limbs and gait, and d absence of lower limb tendon reflexes. METHODS: We studied the frequency and the size of expanded GAA and their influence on neurologic findings, age at onset, and disease progression in 25 Brazilian patients with clinical diagnosis of Friedreich's ataxia - 19 typical and 6 atypical - using a long-range PCR test. RESULTS: Abnormalities in cerebellar signs, in electrocardiography, and pes cavus occurred more frequently in typical cases; however, plantar response and speech were more frequently normal in this group when the both typical and atypical cases were compared. Homozygous GAA expansion repeats were detected in 17 cases (68% - all typical cases. In 8 patients (32% (6 atypical and 2 typical, no expansion was observed, ruling out the diagnosis of Friedreich's ataxia. In cases with GAA expansions, foot deformity, cardiac abnormalities, and some neurologic findings occurred more frequently; however, abnormalities in cranial nerves and in tomographic findings were detected less frequently than in patients without GAA expansions. DISCUSSION: Molecular analysis was imperative for the diagnosis of Friedreich's ataxia, not only for typical cases but also for atypical ones. There was no genotype-phenotype correlation. Diagnosis based only on clinical findings is limited; however, it aids in better screening for suspected cases that should be tested. Evaluation for vitamin E deficiency is recommended, especially in cases without GAA expansion.

    Nurse educators are finding it increasingly more challenging to prepare undergraduate students for the ever-changing and more acute clinical environment. As an answer to this dilemma, the human patient simulator can provide students with the opportunity to enhance knowledge, to facilitate skill acquisition, to decrease anxiety, and to promote clinical judgment in a safe environment. These experiences assist the novice nursing student to progress to the advanced beginner stage of practice. This article describes how faculty used the human patient simulator in creating a case scenario that enhanced critical thinking in senior nursing students.

    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.

    This manuscript provides a review of the clinical case study within the field of psychoanalytic and psychodynamic treatment. The method has been contested for methodological reasons and because it would contribute to theoretical pluralism in the field. We summarize how the case study method is being applied in different schools of psychoanalysis, and we clarify the unique strengths of this method and areas for improvement. Finally, based on the literature and on our own experience with case study research, we come to formulate nine guidelines for future case study authors: (1) basic information to include, (2) clarification of the motivation to select a particular patient, (3) information about informed consent and disguise, (4) patient background and context of referral or self-referral, (5) patient's narrative, therapist's observations and interpretations, (6) interpretative heuristics, (7) reflexivity and counter-transference, (8) leaving room for interpretation, and (9) answering the research question, and comparison with other cases.

    Clinical placement is a valuable component of nursing education, helping students to authenticate, integrate and develop a range of nursing skills and knowledge. The diversity of nursing curricula throughout the world and the many models of clinical placement make this a difficult subject to research using typical qualitative and quantitative research methodologies. The potential for case study methodology to address the complexity of learning in the clinical environment is significant. This paper argues that Complexity Theory provides an interpretive paradigm that articulates well with case study methodology. This paper also provides an example of the development of a theoretical proposition based on pattern matching. Pattern matching is an approach to data analysis that encourages a consideration of predicted patterns with those that are empirically based. Copyright © 2012 Elsevier Ltd. All rights reserved.

  8. A case for human systems neuroscience.

    2015-06-18

    Can the human brain itself serve as a model for a systems neuroscience approach to understanding the human brain? After all, how the brain is able to create the richness and complexity of human behavior is still largely mysterious. What better choice to study that complexity than to study it in humans? However, measurements of brain activity typically need to be made non-invasively which puts severe constraints on what can be learned about the internal workings of the brain. Our approach has been to use a combination of psychophysics in which we can use human behavioral flexibility to make quantitative measurements of behavior and link those through computational models to measurements of cortical activity through magnetic resonance imaging. In particular, we have tested various computational hypotheses about what neural mechanisms could account for behavioral enhancement with spatial attention (Pestilli et al., 2011). Resting both on quantitative measurements and considerations of what is known through animal models, we concluded that weighting of sensory signals by the magnitude of their response is a neural mechanism for efficient selection of sensory signals and consequent improvements in behavioral performance with attention. While animal models have many technical advantages over studying the brain in humans, we believe that human systems neuroscience should endeavor to validate, replicate and extend basic knowledge learned from animal model systems and thus form a bridge to understanding how the brain creates the complex and rich cognitive capacities of humans.

    In the past six years, we have had experience with 40 patients with hypertensive thalamic hemorrhages, as verified by CT scan at our hospital within 24 hours. These patients were classified into the following three groups according to the location of the bleeding point and the size of the hematoma: (1) anteromedial (4 cases), (2) posterolateral (16 cases), and (3) massive (20 cases). The (1) and (2) hematomas were small (less than 3 cm in diameter), while those in (3) were large (more than 3 cm in diameter). Twenty cases (50% of all the thalamic hematomas) were small hematomas. The characteristic clinical symptoms of the anteromedial type were a mild disturbance of consciousness and thalamic dementia, while those of the posterolateral type were motor and sensory disturbance, and thalamic aphasia, respectively. Twenty cases (50%) were large hematomas. The clinical symptoms of these cases were mainly consciousness disturbance; 7 of them expired. Based on this experience, it may be considered that the patients whose hematoma size was larger than 3 cm had a poor prognosis and that the patients with the posterolateral type had a poor functional diagnosis.

    Full Text Available From 1981 to 1992, 109 cases (90 females and 19 males of pemphigus were seen in the Department of Dermatology, Central Hospital Tripoli, Libya. Age of onset of the disease varied from 17 to 85 years, while duration of the disease at the time of presentation varied from 3 days to 13 days. On the basis of clinical features and routine histological findings the cases were divided into various subtypes as : pemphigus foliaceus 65 cases, pemphigus vulgaris 34 patients, pemphigus erythematosus 5, herpetiform pemphigus 3 and vegetans type 2 cases. Three of our patients had diabetes mellitus preceding pemphigus, while 12 patients developed steroid induced diabetes. Significant secondary bacterial infection occurred in all cases at some stage of the disease while oral candidiasis occurred in 15 cases. Eczema herpeticum was seen in 4 patients, while 2 had extensive tinea corporis. One of 4 patients of pemphigus vulgaris had complete shedding of nail and 1 female patient had alternate phases of pemphigus foliaceus and generalized pustular psoriasis. The features in our cases of pemphigus foliaceus were somewhat similar to Brazilian pemphigus foliaceus and we had more cases of pemphigus foliaceus, almost exclusively affecting females.

    Nineteen cases are described, including 12 cases from three different families and 7 nonfamilial cases, in which multisystem neurological disease was associated with acanthocytosis in peripheral blood and normal plasma lipoproteins. Mild acanthocytosis can easily be overlooked, and scanning electron microscopy may be helpful. Some neurologically asymptomatic relatives with significant acanthocytosis were identified during family screening, including some who were clinically affected. The mean age of onset was 32 (range 8-62) yrs and the clinical course was usually progressive but there was marked phenotypic variation. Cognitive impairment, psychiatric features and organic personality change occurred in over half the cases, and more than one-third had seizures. Orofaciolingual involuntary movements and pseudobulbar disturbance commonly caused dysphagia and dysarthria that was sometimes severe, but biting of the lips or tongue was rarely seen. Chorea was seen in almost all symptomatic cases but dystonia, tics, involuntary vocalizations and akinetic-rigid features also occurred. Two cases had no movement disorder at all. Computerized tomography often demonstrated cerebral atrophy. Caudate atrophy was seen less commonly, and nonspecific focal and symmetric signal abnormalities from the caudate or lentiform nuclei were seen by magnetic resonance imaging in 3 out of 4 cases. Depression or absence of tendon reflexes was noted in 13 cases and neurophysiological abnormalities often indicated an axonal neuropathy. Sural nerve biopsies from 3 cases showed evidence of a chronic axonal neuropathy with prominent regenerative activity, predominantly affecting the large diameter myelinated fibres. Serum creatine kinase activity was increased in 11 cases but without clinical evidence of a myopathy. Postmortem neuropathological examination in 1 case revealed extensive neuronal loss and gliosis affecting the corpus striatum, pallidum, and the substantia nigra, especially the pars

    Full Text Available Knowledge, qualifications of workforce and human capital became key factors for progress. Human capital flight transfers not only people but work, knowledge, tangible and intangible capital and development potential. In this article, trying to answer whether Romania is a source country for emigration of highly skilled or well-educated individuals (ie human capital flight I flew over those two dimensions that have traditionally characterized human capital flight namely: shrinking work resource and lossing high educated peoples. Therefore, Romania was faced with decreasing the number of resident population due to the evolution of demographic phenomena with negative projections and declining number of working age population and young educated and highly skilled workers and professionals. This will generate complex problems for economy, labour market, difficulty in finding highly skilled workers, talent shortages etc so it’s critical to monitor the labour migration or brain drain phenomenon.

    2011-01-01

    Full Text Available Background: Crescentic glomerulonephritis (CrGN, defined as crescents involving more than 50% of the glomeruli, includes pauci-immune, immune complex-mediated and anti-glomerular basement membrane disease. Objectives: The present study was aimed at evaluating the various clinical, biochemical and histological parameters in CrGN with respect to these categories and clinical outcome. Materials and Methods: Renal biopsies diagnosed as CrGN between Jan 2008 and Feb 2010 were included. Clinical and laboratory parameters were retrieved along with the therapeutic approach and clinical outcome, wherever available. Renal biopsy slides were evaluated for various glomerular, tubulo-interstitial and arteriolar features. Appropriate statistical tests were applied for significance. Results: A total of 46 cases of CrGN were included; majority (71.7% of cases were pauci-immune (PI while 28.3% were immune complex-mediated (IC. Among clinical features, gender ratio was significantly different between PI and IC groups (P = 0.006. The various histological parameters, including proportion of cellular crescents, tuft necrosis and Bowman′s capsule rupture, were similar in both the groups. Four unusual associations, including idiopathic membranoproliferative glomerulonephritis (MPGN, multibacillary leprosy, acute lymphoblastic leukemia and C1q nephropathy were detected. Adequate follow-up information was available in 21 (46% of the patients. Of these, 11 (52.4% were dialysis-dependent at the last follow-up. Adult patients required renal replacement therapy more frequently than pediatric cases (P = 0.05. Presence of arteriolar fibrinoid necrosis also showed association with poor clinical outcome (P = 0.05. Conclusions: Crescentic glomerulonephritis remains one of the main causes of acute renal failure with histological diagnosis. Immunohistologic examination is essential for accurate classification into one of the three categories. This condition should be considered

    Full Text Available Objective – a description of clinical cases of impulsive­compulsive disorders in Parkinson,s disease. The first clinical case. Patient N., 75 years old, suffering for 15 years from Parkinson,s disease, akinetic­rigid form of the disease, stage 4 by Hyun–Yar. Since 2009, he received levodopa/carbidopa 250/25 mg 5 times/day (daily dose of 1250 mg of levodopa; pramipexole 3.5 mg per day (daily dose 3.5 mg, amantadine sulfate 100 mg 5 times/day (daily dose 500 mg. While taking antiparkinsonian drugs the patient developed behavioral disorders such as dopamine disregulatory syndrome combined with punding, hypersexuality and compulsive shopping accompanied by visual hallucinations. The total equivalent dose of levodopa was 1600 mg per day. The second clinical case. Patient R., 52 years old, suffers from Parkinson,s disease about 5 years, a mixed form. She complained of slowness of movement, tremor in her left hand, sleep disturbances, poor mood. The clinic was appointed piribedil 50 mg 3 times per day. Despite the fact that the patient took only one of dopaminergic drugs in a therapeutic daily dose, she developed impulsive­compulsive disorder as hyper­ sexuality, compulsive shopping and binge eating. Results. In the first clinical case for correction of behavioral disorders in patients with Parkinson,s disease levodopa/carbidopa dose was reduced to 750 mg per day (3/4 Tab. 4 times a day; added to levodopa/benserazide dispersible 100 mg morning and levodopa/benserazide 100 mg before sleep (total dose of levodopa of 950 mg per day. Amantadine sulfate and pramipexole were canceled. It was added to the therapy of atypical neuroleptic clozapine dose 6,25 mg overnight. After 3 months marked improvement, regressed visual hallucina­ tions, improved family relationships, background mood became more stable. The patient continue to sing karaoke, but this hobby has be­ come less intrusive. In the second clinical event correction impulsive

    Clinical guidelines (GL) play an important role in medical practice: the one of optimizing the quality of patient care on the basis of the best and most recent evidence based medicine. In order to achieve this goal, the interaction between different actors, who cooperate in the execution of the same GL, is a crucial issue. As a matter of fact, in many cases (e.g. in chronic disease treatment) the GL execution requires that patient treatment is not performed/completed in the hospital, but is continued in different contexts (e.g. at home, or in the general practitioner's ambulatory), under the responsibility of different actors. In this situation, the correct interaction and communication between the actors themselves is critical for the quality of care, and human resources coordination is a key issue to be addressed by the managers of the involved healthcare service. In this paper we describe how computerized GL management can be extended in order to support such needs, and we illustrate our approach by means of a practical case study.

  19. Evaluating physicians' professionalism and humanism: the case for humanism "connoisseurs".

    Science.gov (United States)

    Misch, Donald A

    2002-06-01

    Physicians' professionalism and humanism have become central foci of the efforts of medical educators as the public, various accrediting and licensing agencies, and the profession itself have expressed concerns about the apparent erosion of physicians' competency in these aspects of the art, rather than the science, of medicine. Of the many obstacles to enhancing trainees' skills in these domains, one of the most significant is the difficulty in assessing competency in physicians' professionalism and humanism. The author suggests that the assessment of these aspects of the art of medicine has more in common with the approaches used in criticism of the arts than with the quantitative assessment tools appropriate to the scientific method and the medical model. Quantitative and semi-quantitative tools, so effective in elucidating the etiology, pathophysiology, and treatment of disease, are often in-appropriate and invalid when applied to evaluation of professional and humanistic competencies. The author proposes that humanism "connoisseurs" be employed to qualitatively evaluate medical trainees' professionalism and humanism. Such connoisseurs would possess expert knowledge, training, and experience in the interpersonal aspects of the art of medicine, allowing them to deconstruct concepts such as empathy, compassion, integrity, and respect into their respective key elements while evaluating physicians' behaviors as an integrated, cohesive whole. Through the use of a rich descriptive vocabulary, humanism connoisseurs would provide valid formative and summative feedback regarding competency in medical professionalism and humanism. In the process, they would serve to counteract the relative marginalization of professionalism and humanism in the informal and lived curricula of medical trainees.

    Sometimes, in order to properly restore teeth, surgical intervention in the form of a crown-lengthening procedure is required. Crown lengthening is a periodontal resective procedure, aimed at removing supporting periodontal structures to gain sound tooth structure above the alveolar crest level. Periodontal health is of paramount importance for all teeth, both sound and restored. For the restorative dentist to utilize crown lengthening, it is important to understand the concept of biologic width, indications, techniques and other principles. This article reviews these basic concepts of clinical crown lengthening and presents four clinical cases utilizing crown lengthening as an integral part of treatments, to restore teeth and their surrounding tissues to health.

    We conducted a single case (N-of-1) randomized trial in two patients. In the first case with bronchiolitis obliterans after lung transplantation a beneficial effect of inhaled steroids could be documented. The second patient suffered from symptoms compatible with HIV-associated M. Addison improving after cortisone, but the adrenocortical function was normal. Because the patient required the cortison treatment to be continued, we performed a n-of-1 trial which demonstrated the inefficacy of cortisone. This experience underscores the feasibility and usefulness of N-of-1 randomized clinical trials in medical practice.

    Full Text Available AIM: To analyze the etiology, therapeutic effects,risk of relapse and prognosis of acute anterior uveitis.MEHTODS: Medical history of 215 patients with acute anterior uveitis who underwent treatment in Department of Ophthalmology, People's Hospital of Fenghua was collected, together with results of clinical examinations and auxiliary examinations. The data were studied in terms of therapeutic effects, etiological factors, prognosis and relapse rate. RESULTS: In 85 cases(39.5%, the cause was identified, and among the among the most frequent causes were traumatic or surgical injury, viral infection and glaucomatocyclitic crisis. After treatment, the best corrected visual acuity was no less than 1.0 in 153 cases(71.2%, between 0.5 and 1.0 in 55 cases(25.6%, between 0.3 and 0.5 in 4 cases(1.9%, between 0.05 and 0.3 in 2 cases(0.9%, and less than 0.05 in 1 case(0.5%. During the follow-up of more than 6 months, relapse occurred in 4 cases(1.9%during 4-6 months, in 7 cases(3.2%during 7-12 months, in 10 cases(4.7%during 13-24 months, and in 3 cases(1.4%during 25-60 months. CONCLUSION: The etiology of acute anterior uveitis is complicated and mostly idiopathic. Vision prognosis is good after treatment, but therelapse rate is high and can cause visual impairment, so better understanding should be gained of its relapse and its prevention and early treatment should be emphasized.

    Steatocystoma multiplex (SM) shares many clinical features and may show overlapping histopathological features with eruptive vellus hair cyst (EVHC). Clinical data and pathologic features of 64 patients with SM were evaluated in detail. Most of the cases were sporadic, with an average onset age of 26 years and distribution on the arms, chest, axillae, and neck. All cases exhibited eosinophilic cuticle and lack of granular layer, and 17-42% displayed vellus hair, hair follicles, keratin, and smooth muscle components within the cavity, in the wall, or adjacent to it. The results of this study add further evidence to the hypothesis that SM is a hamartomatous condition and that SM and EVHC are variants of one disorder which originates in the pilosebaceous duct.

    The clinical application of positron-emission-tomography-based reporter gene imaging will expand over the next several years. The translation of reporter gene imaging technology into clinical applications is the focus of this review, with emphasis on the development and use of human reporter genes. Human reporter genes will play an increasingly more important role in this development, and it is likely that one or more reporter systems (human gene and complimentary radiopharmaceutical) will take leading roles. Three classes of human reporter genes are discussed and compared: receptors, transporters and enzymes. Examples of highly expressed cell membrane receptors include specific membrane somatostatin receptors (hSSTrs). The transporter group includes the sodium iodide symporter (hNIS) and the norepinephrine transporter (hNET). The endogenous enzyme classification includes human mitochondrial thymidine kinase 2 (hTK2). In addition, we also discuss the nonhuman dopamine 2 receptor and two viral reporter genes, the wild-type herpes simplex virus 1 thymidine kinase (HSV1-tk) gene and the HSV1-tk mutant (HSV1-sr39tk). Initial applications of reporter gene imaging in patients will be developed within two different clinical disciplines: (a) gene therapy and (b) adoptive cell-based therapies. These studies will benefit from the availability of efficient human reporter systems that can provide critical monitoring information for adenoviral-based, retroviral-based and lenteviral-based gene therapies, oncolytic bacterial and viral therapies, and adoptive cell-based therapies. Translational applications of noninvasive in vivo reporter gene imaging are likely to include: (a) quantitative monitoring of gene therapy vectors for targeting and transduction efficacy in clinical protocols by imaging the location, extent and duration of transgene expression; (b) monitoring of cell trafficking, targeting, replication and activation in adoptive T-cell and stem/progenitor cell therapies

    2014-01-01

    Background and Objectives High-dose systemic steroid therapy is the mainstay treatment for sudden sensorineural hearing loss (SSNHL). Recovery rates from SSNHL range are about 47-63% and are influenced by various prognostic factors. To evaluate the prognostic value of specific clinical parameters, we reviewed 289 cases by clinical and statistical analysis. Subjects and Methods This study included 289 patients with SSNHL who visited the Department of Otolaryngology at Soonchunhyang University Hospital from January 2005 to December 2012. The cases were reviewed retrospectively based on clinical charts. Hearing improvement was evaluated in relation to pure-tone audiogram results, duration between SSNHL onset and time of initial treatment, seasonal incidence, dizziness, patient age, degree of hearing loss, patterns of initial pure-tone audiogram and presence of underlying disease. Results Hearing improvement was observed in 196 of 289 (67.8%) patients; such improvement began within 7 days in most patients, followed by rapid hearing recovery. Cases that failed to show improvement within 14 days were unlikely to achieve hearing recovery. The more severe the hearing loss during the early stage, the lower the hearing recovery rates. Patients aged less than 60 years appear to have better prognosis of hearing improvement compared to those who are over 60 years. Conclusions Important prognostic factors for recovery in patients with SSNHL include the time of initiating treatment after symptom onset, the degree of early-stage hearing loss, and the age of the affected patient.

    2007-02-01

    Full Text Available Abstract Background Atypical scrapie is a recently recognised form of transmissible spongiform encephalopathy of sheep that differs from classical scrapie in its neuropathological and biochemical features. Most cases are detected in apparently healthy sheep and information on the clinical presentation is limited. Case presentation This report describes the clinical findings in two sheep notified as scrapie suspects and confirmed as atypical scrapie cases by immunohistochemistry and Western immunoblotting. Although both sheep displayed signs suggestive of a cerebellar dysfunction there was considerable variation in the individual clinical signs, which were similar to classical scrapie. Conclusion Any sheep presenting with neurological gait deficits should be assessed more closely for other behavioural, neurological and physical signs associated with scrapie and their presence should lead to the suspicion of scrapie.

    Full Text Available Onychomycosis or fungal infection of the nails is a common disease, especially in older persons. A mycological study of onchomycosis was undertaken in 75 patients. The nails were judged to be infected by their clinical appearance. There were a total of 75 suspected cases of onychomycosis. Of these 75 cases 22.6% were positive by direct microscopy and 33.3% were culture positive. Of these 75 cases, 18 were males (24% and 57 (76 % were females, male to female ratio being. The commonest age group was 31-40 years followed by 21-30 years. The finger nails were more frequently involved. i.e. 45 (60 %, followed by toe nails 30 (40 % and both in 18 (24% cases. Ratio of finger nail to toe nail infection was 1.5:1. Distal and lateral subungual onychomycosis (DLSO was the commonest clinical pattern (76% followed by total dystrophic onychomycosis (18.66% and then superficial white onychomycosis (4% and proximal subungual onychomycosis (1.33%. The most common fungal isolates were dermatophytes of which 44% were Trytophyton rubrum, 4% were Trytophyton mentagrophytes. Non dermatophyte moulds constituted 16% of the fungus isolates. Onychomycosis was found to be the commonest in housewives (52%, followed by serviceman / businessman (32% followed by farmers (8% and labourer and student 4% each.

    Full Text Available Objective: To evaluate five biomarkers (neopterin, vascular endothelial growth factor-A, thrombomodulin, soluble vascular cell adhesion molecule 1 and pentraxin 3 in differentiating clinical dengue cases. Methods: A prospective cohort study was conducted whereby the blood samples were obtained at day of presentation and the final diagnosis were obtained at the end of patients’ follow-up. All patients included in the study were 15 years old or older, not pregnant, not infected by dengue previously and did not have cancer, autoimmune or haematological disorder. Median test was performed to compare the biomarker levels. A subgroup Mann-Whitney U test was analysed between severe dengue and non-severe dengue cases. Monte Carlo method was used to estimate the 2-tailed probability (P value for independent variables with unequal number of patients. Results: All biomarkers except thrombomodulin has P value < 0.001 in differentiating among the healthy subjects, non-dengue fever, dengue without warning signs and dengue with warning signs/severe dengue. Subgroup analysis for all the biomarkers between severe dengue and non-severe dengue cases was not statistically significant except vascular endothelial growth factor-A (P < 0.05. Conclusions: Certain biomarkers were able to differentiate the clinical dengue cases. This could be potentially useful in classifying and determining the severity of dengue infected patients in the hospital.

    Full Text Available Aim. This paper investigated the pathogenesis and treatment strategies of acute pancreatitis (AP in pregnancy. Methods. We analyzed retrospectively the characteristics, auxiliary diagnosis, treatment strategies, and clinical outcomes of 26 cases of patients with AP in pregnancy. Results. All patients were cured finally. (1 Nine cases of 22 mild acute pancreatitis (MAP patients selected automatic termination of pregnancy because of the unsatisfied therapeutic efficacy or those patients’ requirements. (2 Four cases of all patients were complicated with severe acute pancreatitis (SAP; 2 cases underwent uterine incision delivery while one of them also received cholecystectomy, debridement and drainage of pancreatic necrosis, and percutaneous jejunostomy. One case had a fetal death when complicated with SAP; she had to receive extraction of bile duct stones and drainage of abdominal cavity after induced abortion. The other one case with hyperlipidemic pancreatitis was given induced abortion and hemofiltration. Conclusions. The first choice of MAP in pregnancy is the conventional therapy. Apart from the conventional therapy, we need to terminate pregnancy as early as possible for patients with SAP. Removing biliary calculi and drainage is supposed to be considered for acute biliary pancreatitis. Lowering blood lipids treatment should be applied to hyperlipidemic pancreatitis or given to hemofiltration when necessary.

  2. Human cysticercosis: parasitology, pathology, clinical manifestations and available treatment.

    Webbe, G

    1994-10-01

    Human cysticercosis is a global health problem and neurocysticercosis a serious clinical syndrome. The diagnosis of neurocysticercosis can now be made with a high degree of accuracy by scrutiny of clinical signs and symptoms in combination with X-ray, computed tomography or magnetic resonance imaging, serological tests and laboratory examinations. Differential clinical diagnosis with tumor, and vascular and inflammatory conditions, may however, prove difficult in nonendemic areas. The management of cysticercosis has been radically changed by the advent of effective chemotherapy. Both the heterocyclic pyrazinoisoquinoline compound, praziquantel and the benzimidazole carbamate, albendazole, have now been extensively tested and successfully used for treatments of neurocysticercosis, usually in combination with corticosteroids. The definition of appropriate criteria and guidelines for the use of chemotherapy, may however, require further research. Surgical interventions continue to play an important role in certain clinical presentations. Recent advances in immunological research hold realistic promise for the development of a vaccine against Taenia solium.

    Full Text Available BACKGROUND: Array Comparative Genomic Hybridization (a-CGH is a powerful molecular cytogenetic tool to detect genomic imbalances and study disease mechanism and pathogenesis. We report our experience with the clinical implementation of this high resolution human genome analysis, referred to as Chromosomal Microarray Analysis (CMA. METHODS AND FINDINGS: CMA was performed clinically on 2513 postnatal samples from patients referred with a variety of clinical phenotypes. The initial 775 samples were studied using CMA array version 4 and the remaining 1738 samples were analyzed with CMA version 5 containing expanded genomic coverage. Overall, CMA identified clinically relevant genomic imbalances in 8.5% of patients: 7.6% using V4 and 8.9% using V5. Among 117 cases referred for additional investigation of a known cytogenetically detectable rearrangement, CMA identified the majority (92.5% of the genomic imbalances. Importantly, abnormal CMA findings were observed in 5.2% of patients (98/1872 with normal karyotypes/FISH results, and V5, with expanded genomic coverage, enabled a higher detection rate in this category than V4. For cases without cytogenetic results available, 8.0% (42/524 abnormal CMA results were detected; again, V5 demonstrated an increased ability to detect abnormality. Improved diagnostic potential of CMA is illustrated by 90 cases identified with 51 cryptic microdeletions and 39 predicted apparent reciprocal microduplications in 13 specific chromosomal regions associated with 11 known genomic disorders. In addition, CMA identified copy number variations (CNVs of uncertain significance in 262 probands; however, parental studies usually facilitated clinical interpretation. Of these, 217 were interpreted as familial variants and 11 were determined to be de novo; the remaining 34 await parental studies to resolve the clinical significance. CONCLUSIONS: This large set of clinical results demonstrates the significantly improved sensitivity

    2015-01-01

    Distal radioulnar arthroplasty is an attractive solution for treating various pathological conditions of the distal radioulnar joint because it allows restoration of stability, load transmission and function. The main indications are: radioulnar impingement after partial or complete resection of the distal ulna; and degenerative, inflammatory or post-traumatic arthritis of the distal radioulnar joint. The authors present three clinical cases of distal radioulnar pathological conditions: two patients with post-traumatic sequelae and one case of distal radioulnar impingement after a Sauvé-Kapandji operation. The three cases were treated surgically with a metallic prosthesis to replace the distal ulna (First Choice - Ascension®). The first two were treated with a resurfacing prosthesis and the last one with a modular prosthesis. All of the patients had achieved pain relief and increased movement of the distal radioulnar joint after one year of postoperative follow-up. PMID:27047827

  5. Dual cusped protostylid: Case report and clinical significance

    2016-01-01

    Full Text Available Protostylids are superstructures on maxillary or mandibular molars, which have rarely been reported in literature, and the significance of their presence has also been underestimated. The dental practitioners may easily misdiagnose a tooth, with such conical tubercles as malformed tooth. Interestingly, this is neither a malformation nor an anomaly but rather an important morphological trait of an individual. Once in a while, one may come across such a distinct morphological trait without being able to diagnose. To the authors' best knowledge, only one similar case has been reported previously, and the second such case internationally. Bearing all such facts in mind, the authors attempt to educate the readers towards the existence of such a trait so that it can be identified and studied in larger numbers. Hence, it is the authors' endeavor to report an unusual case of dual cusped maxillary protostylid along with its clinical significance.

    Full Text Available Bite is a type of wound received from the teeth of an animal, including humans. Human bites are third leading cause of all bites after dog and cat bites. Human bites are severe wounds due to the risk of contamination with mix oral flora and rapid tissue destruction. Bite wounds created by humans are seen in variety of circumstances including aggression, rape, murder, and child abuse. Oral cavity contains beta-hemolytic streptococci, anaerobes and other microorganisms. There have been reported cases of septicemia, severe necrotizing fasciitis, HIV infection, and death caused by human bites. Early reporting and treatment of bite wounds decrease the number and severity of wound infection. Here, we present the case of human bite in a nine-day-old girl and discuss the treatment approaches in the light of the relevant literature.

    OBJECT Adrenocorticotropic hormone (ACTH) adenomas have been recognized as a more aggressive and invasive subtype of pituitary adenomas. An additional and clinically relevant peculiarity of these tumors is their ability to modify their clinical expression from a silent form to Cushing disease or vice versa. The aim of this study was to review a series of patients with pituitary adenomas and analyze the clinical implications of the transformation of clinical expression in 5 cases that showed this phenomenon. METHODS The authors retrospectively reviewed a series of patients with pituitary adenoma and collected clinical, biohumoral, and neuroradiological data of those who presented with a transformation from silent ACTH adenomas to functioning tumors or vice versa. In all the cases, preoperative assessment consisted of brain MRI, ophthalmological examination, and complete baseline endocrinological investigation. In patients with clinical and/or biochemical findings suspicious for Cushing syndrome, a low-dose dexamethasone suppression test was performed to rule in or out this diagnosis. Endocrinological evaluations were repeated 1 month after surgery, 3 months after surgery, and every 6 months or annually thereafter. Ophthalmological evaluations and brain MRIs were repeated after 3 months and then every 6 or 12 months thereafter. RESULTS Five patients (2 men and 3 women) included in this series had corticotropic tumors that showed transformation from an endocrinologically silent form to manifest Cushing disease and vice versa. The mean age at presentation was 40 years (range 18-51 years). In 3 of these patients, a transformation from silent to functioning ACTH adenoma with manifest Cushing disease occurred. In 1 patient, the authors observed the transition from a functioning to a silent adenoma with spontaneous resolution of hypercortisolism. Another patient's silent adenoma "shifted" to a functioning adenoma and then regressed back to a silent form with spontaneous

    Full Text Available Background and Design: Sweet syndrome is an inflammatory disease characterized by the abrupt onset of pain, red papules and plaques, fever, neutrophilic leukocytosis, and dermal neutrophilic infiltrate. There are not enough data about Sweet syndrome in Turkey. In this article, we studied clinical, laboratory, histopathological, and epidemiological characteristics of patients, who presented to our clinic, and compared the findings with the literature. Materials and Methods: All patients diagnosed with Sweet syndrome in our clinic between 2005 and 2011 were included in the study. The epidemiological, clinical, and laboratory findings were retrospectively evaluated. Results: A total of 31 patients with Sweet’s syndrome - 24 female (77.4%, 7 male (22.6%; aged 23-82 years – included in the study. The average age of the patients was 48 years. Cutaneous lesions were most frequently localized in the upper extremity. Conjunctivitis was the common systemic manifestation, followed by fever, arthralgia, and myalgia. The most common trigger factor was infections of the upper respiratory tract. In histopathological evaluations of skin biopsies, dense neutrophil infiltration compatible with Sweet syndrome was detected in the dermis. Also, findings of vasculitis were determined in 3 patients. Discussion: The clinical and laboratory findings in our study are mostly similar to those reported in the literature. We found evidence of vasculitis in 10% of cases, therefore, we think the presence of vasculitis does not necessarily rule out the diagnosis of Sweet syndrome

    Full Text Available ObjectiveTo investigate the characteristics, management, and outcome of cholelithiasis patients treated in the Lanzhou region of China. MethodsThe clinical data of 2180 cases of cholelithiasis treated between March 2011 and March 2012 were retrospectively collected from the electronic medical records. The significance of differences between each of the features was analyzed by t-test or Chi-squared test. ResultsSurgical intervention was used to treat 84.6% (n=1845 of the cases, of which 1844 cases were cured and one died. The remaining 15.4% (n=335 of cases received conservative (non-surgical treatments. Morbidity was higher among women than men (1187/993. Incidence of gallbladder polyps was not correlated with gallstone presence. Laparoscopic cholecystectomy was performed in 1446 cases, and included 1371 cases of laparoscopic cholecystectomy and 399 cases of open cholecystectomy. Both the time and amount of intraoperative bleeding, as well as the time to complete the cholecystectomy, were significantly lower for the laparoscopic procedure than the open procedure (P<0.05. The laparoscopic procedure had a significantly lower incidence of postoperative biliary fistula (vs. open cholecystectomy, P<0.05, but no other complications were significantly different between the two groups. When the overall cases were stratified according to geographical regions of the Lanzhou area, differences were observed in the incidences among females to males, age groups, and dietary practices. ConclusionCompared to open cholecystectomy, laparoscopic cholecystectomy is safer, since it requires a shorter operative time, produces less intraoperative bleeding, and is associated with less postoperative biliary fistula. The etiologies of cholelithiasis vary by geographic region and may help to develop effective targeted preventive strategies.

    2015-01-01

    Several approaches to clinical ethics consultation (CEC) exist in medical practice and are widely discussed in the clinical ethics literature; different models of CECs are classified according to their methods, goals, and consultant's attitude. Although the "facilitation" model has been endorsed by the American Society for Bioethics and Humanities (ASBH) and is described in an influential manual, alternative approaches, such as advocacy, moral expertise, mediation, and engagement are practiced and defended in the clinical ethics field. Our Clinical Ethics Center in Paris was founded in 2002 in the wake of the Patients' Rights Act, and to date it is the largest center that provides consultation services in France. In this article we shall describe and defend our own approach to clinical ethics consultation, which we call the "Commitment Model," in comparison with other existing models. Indeed commitment implies, among other meanings, continuity through time, a series of coherent actions, and the realization of important social goals. By drawing on a recent consultation case, we shall describe the main steps of our consultation procedure: interviews with major stakeholders, including patients and proxies; case conferences; and follow up. We shall show why we have chosen the term "commitment" to represent our approach at three different but interrelated levels: commitment towards patients, within the case conference group, and towards society as a whole.

    In this communication an immunodiagnostic approach has been adopted for detection of antigen and antibody in amicrofilaeamic Mf(-) patients by countercurrent immuno electrophoresis (CCIE) and immunodiffusion (ID). Using Setaria cervi and Immune Complex (IC) antigens, out of fifteen clinical cases the number of positive patients in CCIE were twelve and ten respectively. Sixty percent of the Mf(-) cases were positive in antigen detection against both the homologous and heterologous antibody. In ID nine Mf(-) cases gave precipitin bands against S. cervi antigen while with IC antigens ten patients were positive. In similar experiments, it was found that out of fifteen Mf(-) cases nine and eleven patients were positive in antigen detection against microfilaraemic Mf(+) sera and S. cervi antibody respectively. All the Mf(+) cases were positive in both antibody and antigen detection. From the standpoint of immunodiagnosis the data were analysed by two-way analysis of variance study and a newly developed system using Binomial distribution. The sera from the control group were negative in all the immunodiagnostic tests.

    Full Text Available We report the case of a 64 year-old woman with motor and cognitive deterioration that progressed rapidly during eight months. She was unsuccessfully treated with quinacrine, and died in a terminal status, by septic shock secondary to bronchopneumonia by broncho-aspiration. The brain was donated for research and the histopathological analysis showed spongiform changes, astrogliosis and prion protein (PrPRes deposits, confirmed by Western blot (WB. These features are considered characteristic of prion diseases, which are uncommon in Colombia. We highlight that its diagnosis was made for the first time in this country by the simultaneous use of immunohistochemistry and Western blot.

    The state of Yucatan, in Mexico, is an endemic area for dengue. During 2015, there was an unpredicted increase in the number of expected cases of dengue fever. To describe and analyse the clinical presentation, progress, and management of a case of dengue infection with non-specific clinical manifestations in an infant which resulted in a dengue shock syndrome. One month old infant admitted to hospital with a generalised rash and a history of being bitten by an insect. He was diagnosed with anaphylaxis based on clinical manifestations and anamnesis. While in hospital, he developed hypotension, tachycardia, anaemia, and respiratory distress. He was transferred to the intensive care unit, but died on the fifth day. He tested positive to dengue virus in the PCR test and for IgG antibodies using Elisa. The basic cause of death was dengue shock syndrome. Dengue fever in young infant infections may be afebrile, so it is important to suspect them appropriately in the presence of a generalised rash, tachycardia, and hypotension, in order to avoid the deadly consequences of dengue shock.

    The purpose of the postmortem examination is to offer answers to explain the cause and manner of death. In the case of perinatal, infant and paediatric postmortem examinations, the goal is to identify unsuspected associated features, to describe pathogenic mechanisms and new conditions, and to evaluate the clinical management and diagnosis. Additionally, the postmortem examination is useful to counsel families regarding the probability of recurrence in future pregnancies and to inform family planning. Worldwide the rate of paediatric autopsy examinations has significantly declined during the last few decades. Religious objections to postmortem dissection and organ retention scandals in the United Kingdom provided some of the impetus for a search for non-invasive alternatives to the traditional autopsy; however, until recently, imaging studies remained an adjunct to, rather than a replacement for, the traditional autopsy. In 2012, Sheffield Children's Hospital National Health Service Foundation Trust set up the service provision of minimally invasive fetal, perinatal and neonatal autopsy, while a postmortem imaging service has been running in Melbourne, Australia, since 2008. Here we summarise the essentials of a business case and practical British and Australian experiences in terms of the pathological and radiologic aspects of setting up a minimally invasive clinical service in the United Kingdom and of developing a clinical postmortem imaging service as a complementary tool to the traditional autopsy in Australia.

    Sarcoidosis is a chronic multisystemic granulomatous disease of unknown etiology, characterized by the formation of noncaseating granulomas in the involved organs. Cutaneous involvement is about 25% with different clinical expressions, the lichenoid pattern being one of the rarest types of cutaneous sarcoidosis. Lichenoid sarcoidosis clinically manifests with multiple scale papules involving extensive skin areas, especially the trunk, limbs, and face mimicking a lichen planus. Although diverse histologic patterns have been previously related, a lichenoid granulomatous infiltrate involving the dermo-epidermal junction has never been reported in lichenoid sarcoidosis. We report a case of a 43-year-old woman presenting with skin-colored pruritic papules, slightly scaling in trunk, extremities, and ears. These symptoms condition continued to expand and worsen for several years. The patient was otherwise in good health with no lymphadenopathies. Histopathologic examination of a skin biopsy showed an upper dermal granulomatous infiltrate of epithelioid cells, without necrosis, distributed in a lichenoid pattern with many cytoid bodies. We consider this may be the first case presenting a characteristic microscopic granulomatous lichen-like pattern in the setting of a clinically lichenoid type of sarcoidosis.

    To study the multifaceted biology of prostate cancer, pre-clinical in vivo models offer a range of options to uncover critical biological information about this disease. The human orthotopic prostate cancer xenograft mouse model provides a useful alternative approach for understanding the specific interactions between genetically and molecularly altered tumor cells, their organ microenvironment, and for evaluation of efficacy of therapeutic regimens. This is a well characterized model designed to study the molecular events of primary tumor development and it recapitulates the early events in the metastatic cascade prior to embolism and entry of tumor cells into the circulation. Thus it allows elucidation of molecular mechanisms underlying the initial phase of metastatic disease. In addition, this model can annotate drug targets of clinical relevance and is a valuable tool to study prostate cancer progression. In this manuscript we describe a detailed procedure to establish a human orthotopic prostate cancer xenograft mouse model.

    Lichen sclerosus et atrophicus and limited systemic scleroderma (acrosclerosis) are inflammatory skin diseases that ultimately evolve into two distinct modes of atrophic scar formation, but which can easily be confused clinically. They are very rarely associated. The literature has reported cases in which lichen sclerosus was associated with various forms of scleroderma, but often with localized morphea. The characteristic histopathological picture of lichen sclerosus includes a thin epidermis, with orthohyperkeratosis and vascular degeneration in the basal layer, loss of elastic fibers, and band-like inflammatory infiltrate in the papillary dermis, while systemic sclerosis is characterized by excessive deposition of collagen in the dermis, accompanied by reduction in adnexal structures and their entrapment in collagen, and the presence of perivascular lymphocytic inflammatory infiltrate. We present the case of a 40-year-old female patient clinically diagnosed with systemic scleroderma and lichen sclerosus involving the genital mucosa. Physical examination in conjunction with laboratory findings (elevated antinuclear, anti-Scl-70, anti-SSA antibodies and immunogram) induced the supposition of the coexistence of lichen sclerosus and systemic scleroderma, fact confirmed by pathological examination. Systemic therapy with corticosteroids, immunosuppressive and phlebotropic drugs, peripheral vasodilators and other tropic adjuvants and topically potent topical corticosteroids was initiated. The course was favorable under therapy, the hardened skin slightly regaining elasticity, relief of itching and disappearance of lichen sclerosus lesions. Our case reaffirms the uncommon association of these two disorders. The importance of history, physical and laboratory examinations in making a diagnosis of certainty in emphasized.

    The aim of this study was to identify the sources of sporadic domestic Salmonella cases in Sweden and to evaluate the usefulness of a source-attribution model in a country in which food animals are virtually free from Salmonella. The model allocates human sporadic domestic Salmonella cases...... to different sources according to distribution of Salmonella subtypes in the different sources. Sporadic domestic human Salmonella cases (n=1086) reported between July 2004 and June 2006 were attributed to nine food-animal and wildlife sources. Of all Salmonella cases, 82% were acquired abroad and 2.9% were...... associated with outbreaks. We estimated that 6.4% were associated with imported food, 0.5% with food-producing animals, and 0.6% with wildlife. Overall, 7.7% could not be attributed to any source. We concluded that domestic food-producing animals are not an important source for Salmonella in humans in Sweden...

    2011-09-01

    Polygraph interrogations are used by half of all surveyed juvenile sex offender (JSO) treatment programs in the United States. This is a distinctive and controversial practice that is rarely if ever used with other juvenile delinquent populations, and that is rarely used or is banned from JSO treatment programs in other countries. Clinical polygraphy is an ethically sensitive issue because it involves mental health therapists in involuntary coercive interrogations of minors.

    A patient with antecedent coccidioidal pulmonary cavitary disease who developed an empyema due to Kingella kingae prompted our analysis of the literature regarding this unusual bacterial pathogen. Formerly classified among other genera and considered a nonpathogen, K. kingae has been increasingly recognized as a cause of human infection. While the most commonly diagnosed infections due to this organism are endocarditis and septic arthritis, there have also been isolated reports of bacteremia, diskitis, abscesses, meningitis, and oropharyngeal infections. The treatment of choice is penicillin, to which K. kingae strains are uniformly susceptible. Recognition of the potential pathogenicity of this microorganism in appropriate clinical settings will probably result in more prompt and specific therapy.

    Thrombocytopenia is a common medical problem for which the main treatment is platelet transfusion. Given the increasing use of platelets and the declining donor population, identification of a safe and effective platelet growth factor could improve the management of thrombocytopenia. Thrombopoietin (TPO), the c-Mpl ligand, is the primary physiologic regulator of megakaryocyte and platelet development. Since the purification of TPO in 1994, 2 recombinant forms of the c-Mpl ligand--recombinant human thrombopoietin (rhTPO) and pegylated recombinant human megakaryocyte growth and development factor (PEG-rHuMGDF)--have undergone extensive clinical investigation. Both have been shown to be potent stimulators of megakaryocyte growth and platelet production and are biologically active in reducing the thrombocytopenia of nonmyeloablative chemotherapy. However, neither TPO has demonstrated benefit in stem cell transplantation or leukemia chemotherapy. Other clinical studies have investigated the use of TPO in treating chronic nonchemotherapy-induced thrombocytopenia associated with myelodysplastic syndromes, idiopathic thrombocytopenic purpura, thrombocytopenia due to human immunodeficiency virus, and liver disease. Based solely on animal studies, TPO may be effective in reducing surgical thrombocytopenia and bleeding, ex vivo expansion of pluripotent stem cells, and as a radioprotectant. Ongoing and future studies will help define the clinical role of recombinant TPO and TPO mimetics in the treatment of chemotherapy- and nonchemotherapy-induced thrombocytopenia.

    In the present study, 50 strains of yellow-pigmented gram-positive rods that had been isolated from human clinical specimens and collected over a 5-year period were further characterized by phenotypic and molecular genetic methods. All 50 strains belonged to the genus Microbacterium, and together they represented 18 different species. Microbacterium oxydans (n = 11), M. paraoxydans (n = 9), and M. foliorum (n = 7) represented more than half of the strains included in the present study. The isolation of strains belonging to M. hydrocarbonoxydans (n = 2), M. esteraromaticum (n = 1), M. oleivorans (n = 1), M. phyllosphaerae (n = 1), and M. thalassium (n = 1) from humans is reported for the first time. Microbacterium sp. strain VKM Ac-1389 (n = 1) and the previously uncultured Microbacterium sp. clone YJQ-29 (n = 1) probably represent new species. Comprehensive antimicrobial susceptibility data are given for the 50 Microbacterium isolates. This study is, so far, the largest on Microbacterium spp. encountered in human clinical specimens and outlines the heterogeneity of clinical Microbacterium strains.

    The biological recovery of human skin allografts is the gold standard for preservation in Skin Banks. However, there is no worldwide consensus about specific allocation criteria for preserved human skin allografts with living cells. A report is presented on the results of 5 years of experience of using human skin allografts in burned patient in the Skin and Tissue Bank at the "Instituto Nacional de Rehabilitacion" The human skin allografts were obtained from multi-organ donors. processed and preserved at -80 °C for 12 months. Allocation criteria were performed according to blood type match, clinical history, and burned body surface. Up to now, the Skin and Tissue Bank at 'Instituto Nacional de Rehabilitacion" has processed and recovered 125,000 cm(2) of human skin allografts. It has performed 34 surgical implants on 21 burned patients. The average of burn body surface was 59.2%. More than two-thirds (67.7%) of recipients of skin allografts were matched of the same to type blood of the donor, and 66.6% survived after 126 days hospital stay. It is proposed to consider recipient's blood group as allocation criteria to assign tissue; and use human skin allografts on patiens affected with burns over 30% of body surface (according the "rule of the 9").

    2004-01-01

    When clients and health care providers differ in their understanding of what is right or wrong, an ethical dilemma may arise. Such dilemmas occur in everyday clinical practice. Health care providers have the professional responsibility to analyze these dilemmas. A clinical case study of an ethical dilemma that occurred in a cross-cultural context is examined. The language of the client and provider differed, and no interpreter service was available. Given these conditions, the provider's ethical dilemma was whether, and if so how, to give safe, satisfying care that respected the needs of a client with limited English proficiency. Measuring the morality of the provider's decisions and actions using Rawls' ethical theory of social justice finds deficits. A 10-step Bioethical Decision-Making Model by Thompson is used to demonstrate one method for analyzing the moral dimension of a clinical scenario focusing on the decisions and actions taken by a midwife. Scrutinizing ethically challenging clinical encounters will result in better understanding of the moral dimensions of practice.

  11. Case report medical eponyms: an applied clinical informatics opportunity.

    2012-01-01

    Medical eponyms are medical words derived from people's names. Eponyms, especially similar sounding eponyms, may be confusing to people trying to use them because the terms themselves do not contain physiologically descriptive words about the condition they refer to. Through the use of electronic health records (EHRs), embedded applied clinical informatics tools including synonyms and pick lists that include physiologically descriptive terms associated with any eponym appearing in the EHR can significantly enhance the correct use of medical eponyms. Here we describe a case example of two similar sounding medical eponyms--Wegener's disease and Wegner's disease-- which were confused in our EHR. We describe our solution to address this specific example and our suggestions and accomplishments developing more generalized approaches to dealing with medical eponyms in EHRs. Integrating brief physiologically descriptive terms with medical eponyms provides an applied clinical informatics opportunity to improve patient care.

    The use of bremsstrahlung photons produced by a linac to induce photonuclear reactions is wide spread. However, using a clinical linac to produce the photons is a new concept. We aimed to induce photonuclear reactions on zinc isotopes and measure the subsequent transition energies and half-lives. For this purpose, a bremsstrahlung photon beam of 18 MeV endpoint energy produced by the Philips SLI-25 linac has been used. The subsequent decay has been measured with a well-shielded single HPGe detector. The results obtained for transition energies are in good agreement with the literature data and in many cases surpass these in accuracy. For the half-lives, we are in agreement with the literature data, but do not achieve their precision. The obtained accuracy for the transition energies show what is achievable in an experiment such as ours. We demonstrate the usefulness and benefits of employing clinical linacs for nuclear physics experiments.

  13. Clinical Management of Two Root Resorption Cases in Endodontic Practice

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Root resorption is a pathological process involving loss of hard dental tissues. It may occur as a consequence of dental trauma, orthodontic treatment, and bleaching, and occasionally it accompanies periodontal disease. Although the mechanism of resorption process is examined in detail, its etiology is not fully understood. Wide open apical foramen is more difficult to manage and the root canal may often overfill. In this report we present two cases of root resorption and describe means for its clinical management. We conclude that useful measure of a success or failure in managing root resorption is the persistence of the resorption process. It is a clear sign of an active ongoing inflammatory process and shows the clinical need for retreatment.

    2011-01-01

    Alopecia areata (AA) is a nonscarring hair loss disorder with a 2% lifetime risk. Most patients are below 30 years old. Clinical types include patchy AA, AA reticularis, diffuse AA, AA ophiasis, AA sisiapho, and perinevoid AA. Besides scalp and body hair, the eyebrows, eyelashes, and nails can be affected. The disorder may be circumscribed, total (scalp hair loss), and universal (loss of all hairs). Atopy, autoimmune thyroid disease, and vitiligo are more commonly associated. The course of the disease is unpredictable. However, early, long-lasting, and severe cases have a less favorable prognosis. The clinical diagnosis is made by the aspect of hairless patches with a normal skin and preserved follicular ostia. Exclamations mark hairs and a positive pull test signal activity. Dermoscopy may reveal yellow dots. White hairs may be spared; initial regrowth may also be nonpigmented. The differential diagnosis includes trichotillomania, scarring alopecia, and other nonscarring hair loss disorders such as tinea capitis and syphilis.

    Root resorption associated to orthodontic treatment is of multiple etiologies and a non intentional iatrogenic side effect which exists in almost all the orthodontic treatment. This clinical case of an apparently healthy patient illustrates the occurrence during the orthodontic treatment of a root resorption interesting the left central incisor, victims of previous traumatism and presenting a moderate periodontal attachment loss. The orthodontic treatment was carried out with light and continuous forces and a per-orthodontic periodontal maintenance in respect of periodontal requirements. As soon as the root resorption on the left central incisive was diagnosed, the active orthodontic treatment was interrupted in order to stabilize the lesion and a regular clinical and radiological monitoring was established.

    A 6.9 million-feature oligonucleotide array of the human transcriptome [Glue Grant human transcriptome (GG-H array)] has been developed for high-throughput and cost-effective analyses in clinical studies. This array allows comprehensive examination of gene expression and genome-wide identification of alternative splicing as well as detection of coding SNPs and noncoding transcripts. The performance of the array was examined and compared with mRNA sequencing (RNA-Seq) results over multiple independent replicates of liver and muscle samples. Compared with RNA-Seq of 46 million uniquely mappable reads per replicate, the GG-H array is highly reproducible in estimating gene and exon abundance. Although both platforms detect similar expression changes at the gene level, the GG-H array is more sensitive at the exon level. Deeper sequencing is required to adequately cover low-abundance transcripts. The array has been implemented in a multicenter clinical program and has generated high-quality, reproducible data. Considering the clinical trial requirements of cost, sample availability, and throughput, the GG-H array has a wide range of applications. An emerging approach for large-scale clinical genomic studies is to first use RNA-Seq to the sufficient depth for the discovery of transcriptome elements relevant to the disease process followed by high-throughput and reliable screening of these elements on thousands of patient samples using custom-designed arrays.

    21 cases of spinal cord disease were clinically analyzed of which 14 cases were male. 7 female, aged from 30 to 69, weraged 50.9. This group contained 2 cases of consciusness dysfunction. 2l of sensational dysfunction. 19 of morion dysrunction, 11 of aotonomic nerve dysrunction, 2 of, sexual dysfunction. 2 of Brown-Sequrd syndrome. llhad been chrmcally sympromatic for more than two months. the other were of acute for sub acute onset. The segments of the diseases were found mainly at cervical and thoracic ones. to which more attention should be pazd clincally. The incidences of intramedullary lesions were a bit more than that of extramedullary ones. Of the 11 extramendullary cases, 8 arised srorn verteoral body (72.7%), of which 6 cases arisen form the intervertebral dies, or 75%. On which emphasis should be laid clinically Foci in brain and spinal cord were found synchronically in 5 cases (23.8%). They were Wernick cerebral disease, metastetic cerebral tumor, cerebral infarction, polioencephalomyelitis. So possibility of brain disease should also be considerod when diagnosing spinai cord disease, especially in stenosis of cervical canal. Oppressed spinal cord was accodiated with cerebellopontine angle tumor. Disease in brain was negiected because of concermng spinal cord disease and cerehellopontine angie giant meningiona was discovered 5 yeas laaer. There are several methods to diagnose spinal cord disease, including X-rays photography, CSF test, CT, and MRI, etc. X-rays photography should be used for involved vertebral body in lateral and P-A position at first when to suspect spinal cord disease. It should be avoided that neglecting X-rays photography and using CT or MRIfirst. It should be noted when taking segments examination by CT or MRI, thut the actual vertebral body is usually located 7'- 14 segments below the spinal cord involved. Otherwise, misdiagnosis would be resulted. 4 c ases of oppressive spinal cord disease of this group were treated with operating

    Onychocryptosis (ingrown toenail) is a condition commonly seen in Primary Care clinics. It is uncomfortable and restrictive for patients and has a high incidence in males between second and third decades of life. It is of unknown origin, with a number of predisposing triggering factors being involved. Treatment depends on the stage of the ingrown nail and the procedures may range from conservative to minor surgery that can be performed by the Primary Care physician in the health centre. We report the case of a 25-year onychocryptosis that did not respond to conservative management, and was extracted with partial matricectomy of the nail.

    Cysts that may develop in the maxillo-mandibular region and adjacent tissues may be of odontogenic origin, non-odontogenic origin, pseudocysts, cysts associated with the maxillary sinus and those developed from the soft tissues. These may vary as to their histogenesis, frequency, behavior and treatment. This article presents the clinical case of an 18-year-old female patient with an initial radiographic diagnosis of dentigerous cyst, which after exploratory punction and surgical removal under general anesthesia yielded a final diagnosis of odontogenic keratocyst. The patient's evolution was satisfactory with a 2-year radiographic control, without evidence of recurrence.

    Knowledge about the external and internal anatomy of the tooth is essential for successful dental practice. Anomalies in the tooth are often encountered which poses difficulties in dental treatments. As like any other tooth, mandibular first molars are also prone for anatomic malformations. One such anatomic variation is the presence of extra root distolingually. This distolingual root is called radix entomolaris (RE). The presence of an additional root can lead to difficulties during endodontic therapy. This article is a report of two cases describing the management of the first mandibular molars with an RE and clinical guidelines for its management. PMID:27829770

    Initially it has been a tendency to place chondrosarcoma in the general category of osteogenic sarcoma. Jaffe et Lichtenstein claimed that the concept of chondrosarcoma as a separate entity has a firm clinical and histological basis. Chondrosarcomas may arise in peripheral long and flat bones. The maxillary location is very rare, it represents about 0,7% of the whole body. 40 well documented instances are yet counted in the literature. Reporting a personnal case, the author proceeds to a comparative study between the three varieties of maxillary sarcomas, evokes the special histogenesis in this location, he reminds the interest of bone electrocoagulation as curative treatment, and discusses the difficulty in making a prognosis 3 years after surgery without local recurrence or metastasis in this case.

    3 cases of suicide due to ingestion of 150, 200 and 4 gr. of paraquat, respectively, are presented. Two of them were brothers and agricultural industrialists, the other one was a farmer. The first two cases died 16 and 10 hours after intake. The farmer died 21 days after ingestion. All of them had progressive hypoxemia and renal failure the two brothers had heart conduction system glycemia (23 mg/dl) a few hours after ingestion. The postmortem study showed edema, hemorrhage and congestion of the lungs, alveolitis, fibrosis and lobar atelectasia; renal tubular necrosis adrenal necrosis; colestasia; hepatic steatosis focal miocarditis. The clinical evolution, particularly short in the first two patients, is commented on, as well as the post-mortem findings, comparing them with those described in the literature. Finally, due to the high toxicity of this herbicide, we insist in prompt transport to herbicide, we insist in prompt transport to the hospital in order to apply early treatment.

    Full Text Available We report a clinical case of a patient who underwent apicectomy on an upper premolar, presumably by endodontic done improperly, and have cast a bolt where the extraction run the risk of tooth fracture. Failed such treatment, an implant is performed, placed immediately after extraction, in which bone filling with xenograft and guided bone regeneration with resorbable collagen membrane was done. From this we deduce that the phase diagnosed is of paramount importance. Two months after functional load of the implant is made with a cemented ceramic crown. One of the factors that influenced the positive outcome of this case, where immediately implants are placed to the tooth extraction is ultra microtextured surface of the used implant, besides being the bone table of these dental elements of thicker vestibular.

    The thyroglossal duct cyst pathology represents the second cause of bening cervical anomalies in childhood. Diagnosis is mainly clinical. Sistrunk (1920) proposed a surgical technique that is still considered the gold standard for definitive treatment of this condition. A retrospective study was made including patients who underwent surgery for thyroglossal duct cyst pathology in our department between June 2008 and August 2015. In this period, we performed 54 procedures in 45 patients (39 primary cases). Median age was 4.7 years; 14/39 patients (31.1%) had pre-operative infection. All patients were studied with neck ultrasound. A Sistrunk's procedure was performed in all cases. The global recurrence rate was 17.8% (8/45).

    Odontogenic Calcificant Cystic Tumor (OCCT) is an infrequent injury. It arises from odontogenic epithelial rests present in the maxilla, jaw or gum. Gorlin and col. described the OCCT for first time as an own pathological entity in 1962. Clinically, the OCCT represents 1% of the odontogenic injuries. It is possible to be found from the first decade to the eighth decade. It affects in same proportion the maxilla and the jaw, being the most common in the dented zones, with greater incidence in the first molar area. Two case reports of OCCT in two different ages, both in female individuals, one at 5 years old and the other at 35 years old are presented. Enucleation of the tumor was the treatment chosen. The purpose of this article is to present a review of the literature related to these two cases of OCCT and its treatment, putting an emphasis on its aetiology, biological behaviour and treatment.

    Burkitt's lymphoma (BL) is a neoplasm which, despite its very aggressive behaviour is potentially curable. It typically affects the paediatric population. BL belongs to the non-Hodgkin lymphomas group, and is the first human tumour undoubtedly related to a viral origin (Epstein-Barr virus). Two main clinical subtypes are recognized: endemic or African type, and sporadic type; HIV associated BL constitutes a third type. Although common in endemic BL, maxillary involvement is rare in sporadic cases. This, together with the clinical lack of specificity associated to this location, makes diagnosis difficult. New chemotherapeutic protocols achieve a high survival rate. Most important prognostic factors are location and tumour stage. We report a paediatric case of BL presenting in the maxilla, with a review and a description of the characteristics of the disease.

    This study presents clinical cases collecting etiologies that are more frequent in the field of complex wounds. All require a specific approach, as well as the interdisciplinary participation of different members of the team. But in general, established local cure plans may be quite similar. Applies them technology lipid colloidal (TLC) which consists of the combination of particles of hydrocolloid (carboxymethylcellulose) with lipid components. Products with a technology designed for every moment of healing. Show our experience in the use of products with TLC in patients with ulcers of different etiologies. The following products depending on the case have been used to treat: UrgoTul Absorb Border, Urgoclean (rope or plate), UrgoStart, UrgoK2 and UrgoK2 LITE. These products were applied in patients presenting four different etiologies of ulcer: hypertensive, traumatic, venous and ischemic ulcer. The use of Urgoclean rope favored cleaning the bed ulceral and applied Urgoclean plate with reinforced alginate to control the abundant exudates, with coverage of UrgoTul ABsorb Border. Once clean beds pass UrgoStart and at all times UrgoK2 bandage, cases that required compressive therapy. Intolerance to that kind of compression applied to patients presenting bandage UrgoK2 LITE (which tolerated without problem) which significantly reduced edema, favoring the control of exudate. Patients with ulcer of long evolution, at the start were reluctant to the application of new technologies, but after the first cures and sensing a good evolution, we get their confidence and commitment to the resolution. Are displayed clinical cases of different etiologic and personal contexts that an integral and interdisciplinary approach together with the application of products with TLC, managed to solve the problem. The materials used have been satisfactory in all cases, with a direct involvement in the resolution of lesions which carries a long unresolved, and in any of them, even with a

    We describe the clinical and genetic characteristics of the 85 definite or probable human prion diseases cases died between January 1993 and December 2002 in Catalonia (an autonomous community of Spain, 6 million population). Seventy-three (86%) cases were sporadic Creutzfeld-Jakob diseases (sCJD) (49 definite, 24 probable), with a median age at onset of 66 years. The clinical presentation was dementia in 29 cases, ataxia in 14 and visual symptoms in five. The median survival was 3 months. The 14-3-3 assay was positive in 93% cases, 62% presented periodic sharp wave complexes (PSWC) in EEG but only 18% the typical signs on MRI. Forty-eight sCJD were studied for codon 129 PRNP polymorphism: 69% were methionine/methionine (M/M), 14.5% valine/valine (V/V) and 16.5% M/V. Six out of seven V/V cases did not present PSWC and in two survival was longer than 20 months. Eleven cases (13%) were genetic: five familial fatal insomnia and six familial CJD (fCJD). Up to four (67%) fCJD lacked family history of disease, two presented seizures early at onset and one neurosensorial deafness. The only iatrogenic case was related to a dura mater graft. No case of variant CJD was registered. The study confirms in our population the consistent pattern reported worldwide on human prion diseases. Atypical features were seen more frequently in sporadic 129 V/V CJD and fCJD cases.

    The clinical case report is generally limited to a description of unusual examples of the complications of disease or responses to therapy. However, it can also be used to present novel hypotheses which have been derived from individual cases. Two examples of this latter genre are presented and updated. These are Syndrome X and the stiff left atrial syndrome. In both instances, general and novel formulations were derived from single cases. With respect to Syndrome X, a hypothesis was generated that the chest pain and ST abnormalities in these patients represent excess activation of adenosine A1 receptors in the absence of myocardial ischemia. With respect to the stiff left atrial syndrome, recognition of the first case led to the recognition of the problem in many others. Now, a variant of the syndrome has been recognized in which mitral regurgitation is also present. In addition, the possibility that tricuspid annuloplasty may rescue patients dying of cardiac cachexia due to right heart failure caused by combined pressure and volume overload of the right ventricle is outlined.

    Full Text Available Abstract Background Infections due to nontyphoidal Salmonella have increased worldwide over the last couple of decades. Salmonella enterica serotype Blockley (Salmonella Blockley infections is associated with chickens and is a rarely isolated serotype in human infections in most countries. Case presentation We report a case of human infections due to Salmonella Blockley in KwaZulu-Natal, South Africa in 2011. Three African males (aged 4, 14 and 16 presented to a clinic with diarrhoea, stomach cramps and headache. They started experiencing signs of illness a day after they consumed a common meal, consisting of meat, rice and potatoes. Stool specimens from the patients cultured Salmonella Blockley. The strains showed an indistinguishable pulsed-field gel electrophoresis pattern. Conclusion This is the first recorded case of human infections due to Salmonella Blockley in South Africa.

    Clinical Data Warehouses (CDW) can complement current Clinical Information Systems (CIS) with functions that are not easily implemented by traditional operational database systems. Here, we describe the design and deployment strategy used at the Pompidou University Hospital in southwest Paris. Four realms are described: technological realm, data realm, restitution realm, and administration realm. The corresponding UML use cases and the mapping rules from the shared integrated electronic health records to the five axes of the i2b2 CDW star model are presented. Priority is given to the anonymization and security principles used for the 1.2 million patient records currently stored in the CDW. Exploitation of a CDW by clinicians and investigators can facilitate clinical research, quality evaluations and outcome studies. These indirect benefits are among the reasons for the continuous use of an integrated CIS.

    For many students in the health sciences, including doctor of pharmacy (PharmD) students, basic and clinical sciences often appear detached from each other. In the infectious disease field, PharmD students additionally struggle with mastering the diversity of microorganisms and the corresponding therapies. The objective of this study was to design an interdisciplinary project that integrates fundamental microbiology with clinical research and decision-making skills. The Emerging Microbe Project guided students through the identification of a microorganism via genetic sequence analysis. The unknown microbe provided the basis for a patient case that asked the student to design a therapeutic treatment strategy for an infected patient. Outside of lecture, students had two weeks to identify the pathogen using nucleotide sequences, compose a microbiology report on the pathogen, and recommend an appropriate therapeutic treatment plan for the corresponding clinical case. We hypothesized that the students would develop a better understanding of the interplay between basic microbiology and infectious disease clinical practice, and that they would gain confidence and skill in independently selecting appropriate antimicrobial therapies for a new disease state. The exercise was conducted with PharmD students in their second professional year of pharmacy school in a required infectious disease course. Here, we demonstrate that the Emerging Microbe Project significantly improved student learning through two assessment strategies (assignment grades and exam questions), and increased student confidence in clinical infectious disease practice. This exercise could be modified for other health sciences students or undergraduates depending upon the level of clinical focus required of the course.

  2. Mapping gene associations in human mitochondria using clinical disease phenotypes.

    2009-04-01

    Full Text Available Nuclear genes encode most mitochondrial proteins, and their mutations cause diverse and debilitating clinical disorders. To date, 1,200 of these mitochondrial genes have been recorded, while no standardized catalog exists of the associated clinical phenotypes. Such a catalog would be useful to develop methods to analyze human phenotypic data, to determine genotype-phenotype relations among many genes and diseases, and to support the clinical diagnosis of mitochondrial disorders. Here we establish a clinical phenotype catalog of 174 mitochondrial disease genes and study associations of diseases and genes. Phenotypic features such as clinical signs and symptoms were manually annotated from full-text medical articles and classified based on the hierarchical MeSH ontology. This classification of phenotypic features of each gene allowed for the comparison of diseases between different genes. In turn, we were then able to measure the phenotypic associations of disease genes for which we calculated a quantitative value that is based on their shared phenotypic features. The results showed that genes sharing more similar phenotypes have a stronger tendency for functional interactions, proving the usefulness of phenotype similarity values in disease gene network analysis. We then constructed a functional network of mitochondrial genes and discovered a higher connectivity for non-disease than for disease genes, and a tendency of disease genes to interact with each other. Utilizing these differences, we propose 168 candidate genes that resemble the characteristic interaction patterns of mitochondrial disease genes. Through their network associations, the candidates are further prioritized for the study of specific disorders such as optic neuropathies and Parkinson disease. Most mitochondrial disease phenotypes involve several clinical categories including neurologic, metabolic, and gastrointestinal disorders, which might indicate the effects of gene defects

    Full Text Available Purpose: To report a case of a 20-year-old female with decreased visual acuity (VA in the left eye (LE. Methods: This is a retrospective and descriptive case report based on data from clinical records, patient observation and analysis of diagnostic tests. Results: A 20-year-old female presented with decreased VA in the LE for 3 days. Best-corrected visual acuity (BCVA was 20/20 in the right eye (RE and 20/40 in the LE. Pupillary function, intraocular pressure, results of external segment examinations and slit-lamp biomicroscopy were normal, bilaterally. RE fundoscopy was normal, and in the LE it revealed papillitis and posterior pole exudative retinal detachment. Optical coherence tomography (OCT confirmed the macular serous retinal detachment and showed thickening of the posterior choroid also revealed by orbital ultrasound and magnetic resonance imaging (MRI. Fluorescein angiography showed angiographic features typical of Vogt-Koyanagi-Harada (VKH disease: disseminated spotted choroidal hyperfluorescence and choroidal multifocal hypofluorescence, multifocal profuse leakage in the retina with pooling, serous retinal detachment and optic disc hyperfluorescence. Serological testing for the diagnosis of infectious pathologies was negative, and the review of systems was normal. The patient received systemic steroids and cyclosporine. LE BCVA improved up to 20/20 at 18 months after the diagnosis, with complete reabsorption of subretinal fluid and normal retinal and choroidal thickness by OCT. Conclusion: Despite the unilateral involvement, the clinical and angiographic features were typical of VKH disease, and ophthalmologists should be aware to recognize this rare clinical variant of the disease.

    The purpose of this paper was to evaluate the relationship between the thrombosis and secretory duct dilation, lesion size, clinical types, nature (primary or recurrent) and duration of illness in the development of ranula. A total of 229 cases of sublingual gland cysts were treated with surgical resection from Jan. 1990 to Feb. 2010. The patients' data were investigated on histopathological findings, size of ranula, the clinical types, nature of ranula (primary or recurrent) and duration of illness. Sections from the paraffin-embedded blocks were HE-stained. CK expression was immunohistochemically detected. Among 229 cases the incidence of venous thrombosis was 58.52%. The incidence of venous thrombosis with or without duct dilation was 73.25% and 26.39% respectively, with a significant difference between the two groups (Pranulas with diameter larger or less than 3 cm was 72.22% and 46.28% (Pranula, plunging ranula and mixed ranula was 49.37%, 77.19% and 85.71% respectively, with a significant difference found between oral and plunging or mixed ranula (Pranula patients with duration of illness longer or less than 3 months was 69.77% and 51.75% (Pranulas was 51.85% and 64.85%, without a significant difference noted between them (P>0.05). It is concluded that the formation of venous thrombosis was related to the dilation of secretory duct, lesion size, clinical types, duration of lesion but formation of venous thrombosis was not related to the nature (primary or recurrent) of ranulas.

  5. Methylene blue for clinical anaphylaxis treatment: a case report

    Directory of Open Access Journals (Sweden)

    Janine Moreira Rodrigues

    Full Text Available CONTEXT AND OBJECTIVE: Nitric oxide has a pathophysiological role in modulating systemic changes associated with anaphylaxis. Nitric oxide synthase inhibitors may exacerbate bronchospasm in anaphylaxis and worsen clinical conditions, with limited roles in anaphylactic shock treatment. The aim here was to report an anaphylaxis case (not anaphylactic shock, reversed by methylene blue (MB, a guanylyl cyclase inhibitor. CASE REPORT: A 23-year-old female suddenly presented urticaria and pruritus, initially on her face and arms, then over her whole body. Oral antihistamine was administered initially, but without improvement in symptoms and signs until intravenous methylprednisolone 500 mg. Recurrence occurred after two hours, plus vomiting. Associated upper respiratory distress, pulmonary sibilance, laryngeal stridor and facial angioedema (including erythema and lip edema marked the evolution. At sites with severe pruritus, petechial lesions were observed. The clinical situation worsened, with dyspnea, tachypnea, peroral cyanosis, laryngeal edema with severe expiratory dyspnea and deepening unconsciousness. Conventional treatment was ineffective. Intubation and ventilatory support were then considered, because of severe hypoventilation. But, before doing that, based on our previous experience, 1.5 mg/kg (120 mg bolus of 4% MB was infused, followed by one hour of continuous infusion of another 120 mg diluted in dextrose 5% in water. Following the initial intravenous MB dose, the clinical situation reversed completely in less than 20 minutes, thereby avoiding tracheal intubation. CONCLUSION: Although the nitric oxide hypothesis for MB effectiveness discussed here remains unproven, our intention was to share our accumulated cohort experience, which strongly suggests MB is a lifesaving treatment for anaphylactic shock and/or anaphylaxis and other vasoplegic conditions.

Degrees of visual loss differed among these patients. They also presented visual field defect and ocular fundus changes. Cerebrospinal fluid (CSF examination showed increased white blood cell and protein. Rapid plasma reagin (RPR assay and Treponema pallidum hemagglutination assay (TPHA in serum were positive. RPR assay/toluidine red unheated serum test (TRUST and TPHA in CSF were positive. Visual-evoked potential (VEP showed prolonged latency and declined amplitude of P100 wave. MRI revealed optic atrophy, abnormal signs in medial orbital part or overall length of optic nerve. The vision was improved after intravenous injection of aqueous penicillin and muscular injection of benzathine benzylpenicillin.  Conclusions Neurosyphilis is a rare cause of optic neuritis. Differential diagnosis should be paid attention on syphilitic optic neuritis from idiopathic optic neuritis and ischemic optic neuropathy. Serologic test and CSF examination will be helpful for a clear diagnosis. Besides, early diagnosis and standard therapy are essential for vision recovery. DOI: 10.3969/j.issn.1672-6731.2016.07.007

    2013-12-01

    Full Text Available The sporadic or chronic use of drugs and alcohol is directly related to conduct disorders and to the triggering of psychopathological states of sub-acute or chronic course. The excessive consumption of alcohol and excessive traffic/consumption of illicit drugs by individuals without mental illness or disability are actions of free will; they are therefore criminally responsible for their behaviour, even if they commit a crime during the state of intoxication, which the individual chose voluntarily to experience. In clinical practice, it is widely accepted that the treatment of these disorders is only effective when the patient accepts it voluntarily and that involuntary commitment (compulsive treatment is only carried out when the psychopathological state associated justifies the presuppositions of Article 12 of the Mental Health Law. However, if the compulsive treatment is of a penal character, mandated by a judge, the individual is obligated to accept treatment, independent of whether or not he suffers from mental illness. The authors present two case studies, one of drug addiction, the other of alcoholism, and discuss the clinical and judicial perspectives on the treatment of these clinical entities.

    Full Text Available Objective To study the clinical features of cryptococcal meningitis (CM and summarize its clinical manifestations, laboratory data, differential diagnosis and treatment, so as to discuss the treatment progress of CM.  Methods Clinical data of 26 cases with CM were retrospectively analyzed, and the treatment experiences were summarized.  Results All patients had headache and fever, and were positive for cerebrospinal fluid (CSF latex agglutination test. Twenty-one patients' CSF smear were found Cryptococcus neoformans. Almost 76.92% (20/26 of patients were cured or became better after receiving combined treatment of amphotericin B, flucytosine and fluconazole. The symptoms and signs of 4 patients who received combined treatment of amphotericin B and voriconazole were greatly improved.  Conclusions CM can prone to be misdiagnosed at early stage. CSF smear and fungi culture are beneficial to the diagnosis. Latex agglutination test is a quick and easy examination to reduce the misdiagnosis rate of CM. The combination of amphotericin B, flucytosine and fluconazole is effective for the treatment of CM. doi: 10.3969/j.issn.1672-6731.2014.08.009

    Lipoma arborescens is a benign tumor, but it may be a reactive process to other disorders, and its clinical, analytical, radiological and ultrasound presentation may be redundant to any synovial tumor. Despite the characteristic feature on magnetic resonance imaging (MRI), the correct differential diagnosis in atypical presentation, and the need for timely removal of the lesion to prevent joint damage, forces, ultimately, to invasive procedures. The clinical case reported here, fourth described in English language publications on the polyarticular form, also presented other specificities related to one of the swellings, in the knee. Because of its atypical location in the popliteal fossa, recurrent episodes of joint effusion, personal history of knee trauma, pulmonary tuberculosis, and family history of rheumatoid arthritis required particular attention. This process was hampered by the refusal of knee (and ankle) surgery by the patient. He accepted surgical removal of the swellings of the wrists, for aesthetical reasons, with pathologic confirmation of the diagnosis, and clinical success in that location. MRI of the knee showed the typical image of lipoma arborescens, but also other changes that compromise the prognosis.

Methods  Clinical data from 20 patients with endoscopically confirmed PCI were retrospectively analyzed. They were admitted to the Chinese PLA General Hospital from June 1995 to June 2015. Results  Among the patients 16 of them were male,and the other four were female. The main clinical manifestations were abdominal distention, diarrhea, abdominal pain and mucous bloody stool. The diagnosis relied mainly on colonoscopy and pathological examination. Laparoscopy assisted colorectal cancer resection was performed in 1 patient, laparostomy and repair of sigmoid colon perforation in 1, endoscopic treatment in 5 cases, drug administration and hyperbaric oxygen therapy in 2, drug treatment alone in 7, and no treatment in 4. Conclusions  The final diagnosis depends on endoscopic findings. No treatment is recommended to patients with no symptoms. The management of patients with PCI includes antibiotics, oxygen therapy, endoscopic therapy, surgery, and appropriate therapy related to the underlying cause of PCI. The prognosis is good.

    Paulo Sérgio Gonçalves da Costa

    Full Text Available Human Ehrlichia chaffeensis infections have been reported in North America, Asia and Europe, but only recently have human cases been reported in Brazil. Nine new human cases of E. chaffeensis infection diagnosed on a clinical and serological basis are reported. Serological tests were performed with indoor slides prepared with CDC stock DH-82 cells infected with E. chaffeensis (Arkansas strain. All but two patients were adults. Seven patients were male and two female. The fever duration varied from 4 to 120 days with a median of 6 days. All patients recalled previous tick attack. IgM was detected in four cases. Influenza like syndrome was the most frequent clinical form affecting five patients. Two patients had fever of unknown origin (FUO, one patient had blood culture-negative endocarditis and one had encephalitis. All patients except one recovered. Two patients were correctly treated. One patient with FUO had AIDS and unexplained pancytopenia. The occurrence of human ehrlichiosis by E. chaffeensis remains to be proved in Brazil; the cases reported here highlight the possibility of such disease occurrence in Brazil.

  15. Enhancement and human nature: the case of Sandel.

    Science.gov (United States)

    Lewens, T

    2009-06-01

    If we assume that "enhancement" names all efforts to boost human mental and physical capacities beyond the normal upper range found in our species, then enhancement covers such a broad range of interventions that it becomes implausible to think that there is any generic ethical case to be made either for or against it. Michael Sandel has recently made such a generic case, which focuses on the importance of respecting the "giftedness" of human nature. Sandel succeeds in diagnosing an important worry we may have about the use of some enhancements by some parents, but his arguments are better understood as opposing "procrustean parenting" rather than enhancement in general.

    The clinical and radiographic findings in 104 patients with chondroblastoma are presented. Pain was an almost constant presenting complaint, often accompanied in the case of para-articular lesions by impaired function of an adjacent joint. The majority (80%) were in long bones with a mean age of presentation of 16 years. The characteristic radiological image of these lesions was an eccentric radiolucency, having a sharply defined sclerotic margin and containing areas of calcification in approximately a third of cases. They were always related to a growth plate. Nearly half were confined to the affected epiphysis or apophysis itself, but most of the remainder had traversed the growth plate to involve also the adjacent metaphysis. The bones around the knee and the proximal ends of the humerus and femur were the sites of predilection. A minority (20%) affected flat bones and short tubular bones of the hand and foot, with a peculiar affinity for the calcaneus and talus. The mean age of presentation of these was 28 years. The radiological pattern was similar, except for a greater tendency to expand the affected bone. Complications included the formation of a secondary aneurysmal bone cyst in 16 cases (10 of them in long bones), one malignant chondroblastoma, and one fibrosarcoma developing after radiation of the original chondroblastoma.

    Rhodococcus equi is an emerging opportunistic human pathogen associated with immunosuppressed people, especially those infected with the human immunodeficiency virus (HIV). This pathogen resides primarily within lung macrophages of infected patients, which may explain in part its ability to escape normal pulmonary defense mechanisms. Despite numerous studies as a pulmonary pathogen in foals, where a plasmid seems to play an important role in virulence, information on the pathogenesis of this pathogen in humans is still scarce. In this study, fluorescence microscopy and vancomycin protection assays were used to investigate the ability of R. equi human isolates to adhere to and to invade the human alveolar epithelial cell line A549. Our findings indicate that some R. equi clinical strains are capable of adhering, entering and surviving within the alveolar cell line, which may contribute to the pathogen persistence in lung tissues.

    Context: Dimethylamine borane (DMAB) is a reducing agent used in nonelectric plating of semiconductors. Exposures are usually through occupational contact. We report here four cases of people who suffered from work-related exposure to DMAB. Case presentation: Three patients exposed to DMAB decontaminated immediately by drinking a lot of water; they reported dizziness, nausea, diarrhea 6–8 hr later. The other patient did not decontaminate at once, and he suffered from more severe symptoms, including dizziness, nausea, limb numbness, slurred speech, irritable mood, and ataxia 13 hr later. Magnetic resonance imaging showed symmetric lesions with hyperintensity on T2WI and FLAIR in bilateral cerebellar dantate nuclei. This patient was readmitted to the hospital due to difficulty in walking and climbing 18 days after exposure. Lower leg weakness and drop foot were found bilaterally. A nerve conduction study revealed polyneuropathy with motor-predominant axonal degeneration. This patient receives regular outpatient followups and still walks with a clumsy gait and has difficulty with hand-grasping activity. Discussion: This case study demonstrates that DMAB is highly toxic to humans through any route of exposure, and dermal absorption is the major route of neurotoxicity. DMAB induces acute cortical and cerebellar injuries and delayed peripheral neuropathy. Relevance: Further investigation of the toxic mechanism of DMAB is warranted. Early decontamination with copious water is the best current treatment for exposure to DMAB. PMID:16330364

    Retrospective investigations of odontomas in Japanese children and one recurrent case were carried out. Thirty-nine cases of odontoma in 38 children were treated in the Paediatric Dentistry Clinic of Niigata University Dental Hospital between September 1979 and December 2002. The patients consisted of 23 males and 15 females and their ages ranged from 1 year 2 months to 14 years old. The chief complaints were delayed tooth eruption in 19 cases (five: primary teeth, 14: permanent teeth), retention of primary teeth in 11, incidentally found on the radiographic examination in eight cases, and swelling of the jaw in one case. Thirty-four cases (87%) were associated with tooth eruption disturbances. The most frequently affected region was the maxillary anterior region. Treatment consisted of surgical removal of odontomas in all cases, after which if the impacted teeth did not erupt, exposure of the crown and/or orthodontic traction was performed. Pathological diagnoses were compound odontoma in 30 cases, complex odontoma (n = 7), and compound and complex odontoma (n = 2). A retrospective study of the radiographs revealed the developing process of odontomas in four cases and odontoma disturbed tooth eruption since the early uncalcified developing stage. A recurrent case was a boy aged 6 years 5 months in whom the first surgical removal of odontoma was performed at the age of 1 year 8 months. Recurrence of an odontoma is very rare, but in very young children odontomas are in the early developing stages, containing uncalcified portions, so it is important to perform periodical observations until the succedaneous teeth erupt.

    Streptococcus salivarius is a normal member of the human oral microbiome that is an uncommon cause of invasive infections. Meningitis is a rare but increasingly reported infection caused by S. salivarius. Despite the growing number of reported cases, a comprehensive review of the literature on S. salivarius meningitis is lacking. We sought to gain a better understanding of the clinical presentation, evaluation, management, and outcome of S. salivarius meningitis by analyzing previously reported cases. In addition to a single case reported here, 64 previously published cases of meningitis were identified for this review. The collected data confirm that most patients presented with classical signs and symptoms of bacterial meningitis with a predominance of neutrophils in the cerebrospinal fluid (CSF) and hypoglycorrhachia. The majority of cases followed iatrogenic or traumatic CSF contamination. Most cases were diagnosed by CSF culture within one day of symptom onset. There was no clear evidence of predisposing co-morbid conditions in patients with meningitis, although in most case reports, limited information was given on the medical history of each patient. Outcomes were generally favorable with antibiotic management. Clinicians should suspect S. salivarius meningitis in patients presenting acutely after medical or surgical procedures involving the meninges.

    The recently initiated human genome project is a large international effort to elucidate the genetic architecture of the genomes of man and several model organisms. The initial phases of this endeavor involve the establishment of rough blueprints (maps) of the genetic landscape of these genomes, with the long-term goal of determining their precise nucleotide sequences and identifying the genes. The knowledge gained by these studies will provide a vital tool for the study of many biologic processes and will have a profound impact on clinical medicine.

    Full Text Available Hemangiosarcoma (HSA is a type of cancer that has different clinical presentations and therefore different effects, since, depending on each case, different treatment options will exist. While in the case of cutaneous HSA the first line of treatment is always surgical removal of the tumor, metastatic foci should be sought and then perform chemotherapy, despite them having a low metastatic potential. Moreover, the low survival that exists in this type of cancer is a factor that should be communicated to those responsible for the pets, so that, with all available information, they can make a free and informed choice about the treatment they want for their pet, considering the financial commitment, survival time and quality of life associated with chemotherapy. This article describes the clinical case of a female greyhound dog of eight years of age that was brought to consultation for a skin tumor on the right hind limb in the distal tibia. She was diagnosed with noninvasive cutaneous HSA through histopathology, reason why the owners chose not to do the chemotherapy; however, 10 months later she presented recurrent skin lesions and a popliteal lymph node corresponding to hemangiosarcoma and hemangioma respectively, and three weeks later the patient developed cardiac tamponade due to a cardiac mass with associated spill, which resulted in her euthanasia.

    Full Text Available Electrolyte imbalance always poses challenging situations to the attending intensivists, particularly if it is associated with endocrinopathies and other comorbidities. One such rare clinical scenario is hypokalemic periodic paralysis (HPP due to hyperthyroidism. The epidemiology of such a condition is slightly higher among males of Asian origin as compared to its universal occurrence. The diagnostic challenges in this clinical situation can lead to higher morbidity if timeliness is compromised from the presentation to active management. Moreover, atypical presentation of this pathologic condition further compounds the problem if it is associated with overt hyperthyroidism. Here, we report a unique case that presented to the emergency medicine department of our institute with weakness of all the four limbs and in which we faced all the diagnostic and management challenges as the clinical condition of hypokalemia was somehow dominated by overt hyperthyroidism.

    Amyloidosis consists of different forms of systemic or isolated organ lesions characterised by fibrillary protein deposits in extra-cellular tissue. The isolated involvement of the larynx is the most frequent form in the ENT sphere. We present a clinical case of a 67 year-old woman addressed for a sub-acute laryngitis resistant to conservative treatment, and finally diagnosed with laryngeal amyloidosis. We reviewed its physiopathology, the scientific literature as well as the different possibilities of management. Laryngeal amyloidosis is rare. A thorough additional work-up for the research of multifocal or systemic forms is highly recommended. The treatment aims at a minimal invasive endoscopic surgery with functional organ preservation.

    Olfactory schwannomas, also described as subfrontal or olfactory groove schwannomas, are very rare tumors, whose pathogenesis is still largely debated. We report a case of olfactory schwannoma in a 39-year-old woman who presented with anosmia and headache. The clinical examination did not show lesions in the nose-frontal region and there was no history of neurofibromatosis. Head MRI and CT scan revealed a lobulated extra-axial mass localized in the right anterior cranial fossa that elevated the ipsilateral frontal pole. Bilateral frontal craniotomy demonstrated a tumor strictly attached to the right portion of the cribriform plate that surrounded the right olfactory tract, not clearly identifiable. The immunohistochemical analysis suggested the diagnosis of typical schwannoma. The patient was discharged without any neurological deficit and a four-month postoperative MRI scan of the brain showed no residual or recurrent tumor. © The Author(s) 2016.

    Infections are an important cause of morbidity and mortality during kidney transplant. In areas where tuberculosis is not endemic, Mycobacteria other than tuberculosis (MOOT), also known as 'atypical' Mycobacteria, are more frequently involved in mycobacterial infections than M. tuberculosis. The incidence of MOOT infection in renal transplant recipients ranges from 0.16 to 0.38 percent. This low rate of reported incidence is, however, often due to delay in diagnosis and lack of therapeutic protocols. Further difficulty is caused by the interaction of antimycobacterial drugs with the post-transplant immunosuppressive regimen, necessitating close monitoring of plasma concentrations and careful dose modification. We present two cases of Mycobacterium Chelonae infection in kidney transplant recipients which differ in both clinical presentation and pharmacological approach.

    Ectasia of the basilar artery (EB) occurs when its diameter is greater than normal along all or part of its course, and/or when it is abnormally tortuous. EB may cause cranial nerve dysfunction, ischemic stroke or subarachnoid hemorrhage, pseudotumor or hydrocephalus. We tried to describe cases of stroke associated with EB, analyze its frequency, clinical aspects, and the mechanisms involved in different forms of its presentation. We found 21 patients with stroke and EB. The association between EB and stroke was more prevalent in males over the age of fifty. Main symptoms were hemiparesia, cranial nerves dysfunction, and cerebellar ataxia. Cerebral infarcts associated with EB were due to different mechanisms: arterial thrombosis, artery-to-artery embolism, mass effect with angulation and obstruction of the vertebral and basilar branches.

    Full Text Available Acute normovolaemic haemodilution (ANH is a technique used to preserve a patient's owns red blood cells and reduce the incidence of heterogeneous blood transfusion. This paper describes the use of the technique in a dog and a kitten. A significant benefit of ANH can be shown in the canine case presented. The dog lost 1800m of blood during surgery but the haematocrit was only reduced to 33% 6 hours after the end of surgery. The kitten, however, did not benefit from ANH. It lost a small volume of blood during surgery and developed complications. This paper also describes some of the potential complications that may occur. To the best of my knowledge, this is the 1st clinical description of ANH in a dog and a cat.

    Full Text Available Introduction: To describe clinical and electrophysiological features of a patient with unilateral Retinitis Pigmentosa (RP. Case: A 29-year-old female with a long history of progressive visual disturbance in the right eye has undergone multiple eye examinations during the past eight years. There was nothing noticeable in her past medical and ocular history. Comprehensive eye examinations were done in the first visit. All data was suggestive of right eye RP. Posterior segment fundal examination findings were: a pallor waxy disc, vessel attenuation, and extended pigmentary degeneration of the mid-peripheral retina. The left eye examination was normal. Comparing the automated 60 degree and 30 degree visual fields of both eyes obviously showed significant defects in the right eye visual field but normal in the left eye.  All of the probable infectious agents, which can cause similar ocular manifestations, were ruled out by serological tests. The standard photopic and scotopic electroretinographies were significantly reduced in amplitude in the right eye; however, they were normal in the left eye. Also, the standard Electro-Oculography (EOG results were the same as the Electro-Retinography (ERG ones in both eyes. Eye examinations were normal in other family members. Over an eight-year follow-up period, progressive deteriorating vision has gradually become more noticeable in the right eye. The left eye has been completely normal since.  This data was compatible with the Francois and Verriesr unilateral RP diagnostic criteria. Conclusion: Clinical signs and symptoms, a minimum of a five-year follow-up period, and confirmatory ERG and EOG are very helpful to diagnose andaffirm the case of unilateral RP.

    Full Text Available BACKGROUND Acute appendicitis remains the most common cause of acute abdomen requiring surgical intervention. Diagnosis of appendicitis is done on clinical grounds. The aetiology and pathogenesis of appendicitis are poorly understood. The cause of pain in the cases with clinical diagnosis of acute appendicitis but intraoperatively normal looking appendix remains controversial. The present study aims at determining the cause of pain in these cases by combining routine histopathology, IHC to investigate the status of the enteric nervous system in normal and inflamed appendices. MATERIALS AND METHODS In the present study, 694 patients who underwent appendicectomy with diagnosis of acute appendicitis were included. In 89 cases, there were no signs of inflammation intraoperatively. These appendix specimens were followed by histopathological examination by H&E staining. 69 out of 89 specimens did not have signs of inflammation in histological examination by H&E staining. Cases which are diagnosed as acute appendicitis but histologically negative in H&E staining are taken as study cases. 49 acute appendicitis cases- histologically positive acute appendicitis (HPAA and 20 appendices from right hemicolectomy specimens were taken as controls. All these specimens were subjected to; 1 Routine Haematoxylin & Eosin staining. 2 Toluidine blue stain for mast cell evaluation. 3 Immunohistochemistry by S-100 stain for evaluating size and number of the ganglia. OBSERVATION The mean mast cell count was more in the histologically negative acute appendicitis group when compared to histologically positive acute appendicitis and control group. The mean size and number of the ganglia were more in the histologically negative acute appendicitis group when compared to histologically positive acute appendicitis and control groups. CONCLUSION Neuronal hypertrophy and mast cells may play a role in the pathogenesis of “appendicitis like pain” in patients with

    If the clinical goal of the periodontal plastic surgery is the complete root coverage of gingival recessions, then the microscopically goal standard is to obtain a true periodontal regeneration. Only the histological examination can reveal cellular events unrolled into the grafted tissue-root surface interface and the nature of the clinically observed attachment. To our knowledge, there are no studies that obtained the biopsies of grafted tissues from humans, in vivo, and so, the aim of the present study was to develop such a method, using a bone marrow biopsy needle. Two patients with gingival recessions were treated with coronally advanced flap and subepithelial connective tissue graft, and the clinical and histological results were observed. Complete root coverage was obtained for both cases. Clinically, the grafted tissues seemed to be attached to the root surfaces. The histological findings revealed dense grafted tissues, providing long-term stability of the area. No ligament or bone, characteristic for periodontal regeneration were observed. However, no sign of healing characterized by a long junctional epithelium was observed either. This indicated that the healing that occurred in our cases was a long connective tissue attachment, which has been shown to be stable over time. However, even if the method we proposed is not invasive, it is very difficult to convince the patient to accept a biopsy elevation once the exposed root surface was covered.

    Full Text Available Case report form (CRF is a specialized document in clinical research. It should be study protocol driven, robust in content and have material to collect the study specific data. Though paper CRFs are still used largely, use of electronic CRFs (eCRFS are gaining popularity due to the advantages they offer such as improved data quality, online discrepancy management and faster database lock etc. Main objectives behind CRF development are preserving and maintaining quality and integrity of data. CRF design should be standardized to address the needs of all users such as investigator, site coordinator, study monitor, data entry personnel, medical coder and statistician. Data should be organized in a format that facilitates and simplifies data analysis. Collection of large amount of data will result in wasted resources in collecting and processing it and in many circumstances, will not be utilized for analysis. Apart from that, standard guidelines should be followed while designing the CRF. CRF completion manual should be provided to the site personnel to promote accurate data entry by them. These measures will result in reduced query generations and improved data integrity. It is recommended to establish and maintain a library of templates of standard CRF modules as they are time saving and cost-effective. This article is an attempt to describe the methods of CRF designing in clinical research and discusses the challenges encountered in this process.

    Full Text Available Abstract Background Coats' disease is a non-hereditary ocular disease, with no systemic manifestation, first described by Coats in 1908. It occurs more commonly in children and has a clear male predominance. Most patients present clinically with unilateral decreased vision, strabismus or leukocoria. The most important differential diagnosis is unilateral retinoblastoma, which occurs in the same age group and has some overlapping clinical manifestations. Case presentation A 4 year-old girl presented with a blind and painful right eye. Ocular examination revealed neovascular glaucoma, cataract and posterior synechiae. Although viewing of the fundus was impossible, computed tomography disclosed total exsudative retinal detachment in the affected eye. The eye was enucleated and subsequent histopathological evaluation confirmed the diagnosis of Coats' disease. Conclusion General pathologists usually do not have the opportunity to receive and study specimens from patients with Coats' disease. Coats' disease is one of the most important differential diagnoses of retinoblastoma. Therefore, It is crucial for the pathologist to be familiar with the histopathological features of the former, and distinguish it from the latter.

    Full Text Available Introduction: The aim of this study is was to evaluate the clinical features of cases with diagnosis of spinal muscular atrophy (SMA. Materials and Methods: Thirty-eight pediatric patients were evaluated retrospectively. All patients were followed in the Pediatric Neurology Department of Erciyes University Faculty of Medicine. The diagnosis of patients had been confirmed by genetic analysis of homozygous deletions of survival motor neuron 1 gene. Detailed history, newborn symptoms, nutritional characteristics, initial complaints, physical examination, concomitant pathologies, genetic characteristics, and treatment modalities were investigated in all patients. Results: The study population consisted of 19 boys (50% and 19 girls (50%. The mean age of patients was 26.9±25.7 months (range: 3-96 months. The mean follow-up period was 12.2±13.3 months (range: 2-48 months. According to SMA classification, 22 patients (57.8% were type 1, 8 patients (21.1% were type 2, and 8 patients were (21.1% type 3. Neonatal respiratory distress, age at early diagnosis, nutritional problems, and recurrent lung diseases were detected as poor prognostic factors. Conclusions: SMA is a neuromuscular disease that requires multidisciplinary approach to medical care. There is a wide range of clinical severity. Identification of poor prognostic factors will help in terms of guiding close monitoring and timely treatments of children with SMA.

    Evaluation of therapeutic results and of the efficacy and effectiveness of treatments is an area of interest both for clinicians and researchers. In general, randomized controlled trial designs have been used as the methodology of choice in which intergroup comparisons are made having a minimum of participants in each arm of treatment. However, these procedures are seldom used in daily clinical practice. Despite this fact, the evaluation of treatment results for a specific patient is important for the clinician in order to address if therapeutic goals have been accomplished both in terms of statistical significance and clinical meaningfulness. The methodology based on the reliable change index (Jacobson y Truax)1 provides an estimate of these two criteria. The goal of this article is to propose a procedure to apply the methodology with a single case study of a woman diagnosed with major depression and treated with electroconvulsive therapy.

    2007-06-01

    Full Text Available Hemivertebra is a congenital malformation, that affects small and brachicephalic breeds particularly those with short and twisted tail. Its origin is hereditary. It becomes from an inappropriate or incomplete embryo development of a vertebrae or due to its vascularization or ossification. Hemivertebras are cuneiform vertebrae and its vertex may be lead dorsally, ventrally or medianly through the mean line. It happens mostly in thoracic vertebras. Symptomatology is varied; the most important is pain, showed by young animals, three or four months of age with weakness of posterior limbs. It could be found pain at back when palpations near the hemivertebra. In puppies with those symptoms, the paralysis in posterior limbs gets worse; they can show muscular atrophy, and no control of bladder and intestines. Final diagnostic of hemivertebra must be done with radiological studies of spinal column and the treatment consists in decompress the vertebral body involved and a stabilization of the spinal column. This study presents the case of a male Bulldog, six months old, which is taken to the clinic because of pain, and neurological symptomatology and after many clinical exams a hemivertebra was confirmed. The patient had a surgery for its treatment and all steps of the surgical process are shown.

    During the last three years the School of Nursing and Midwifery at the University of Tasmania has used a needs assessment survey to explore the needs of organizations and nursing professionals that facilitate and clinically supervise Bachelor of Nursing students in the workplace. Findings from the survey indicated that staff at healthcare organizations wanted a communication strategy that was easily accessible by clinicians who supervised students during work integrated learning placements. In particular they wanted to receive timely information related to the role and function of supervisors in practice. The development of the digital strategy to strengthen the development of a community of practice between the University, organizations, facilities and clinical supervisors was identified as the key method of improving communication. Blogging and micro blogging were selected as methods of choice for the implementation of the digital strategy because they were easy to set up, use and enable equity of access to geographically dispersed practitioners in urban and rural areas. Change champions were identified to disseminate information about the strategy within their workplaces. Although clinicians indicated electronic communication as their preferred method, there were a number of human factors at a systems and individual level identified to be challenges when communicating with clinical supervisors who were based off-campus. Information communication technology policies and embedded culture towards social presence were impediments to using this approach in some organizations. Additionally, it was found that it is necessary for this group of clinicians to be educated about using digital methods to undertake their role as clinical supervisors in their varied clinical practice environments.

The main group included patients (n=7, men who survived 7—10 days and 70—90 days after cardiac arrest and later died due to heart failure. The control group (n=4, men included individuals after sudden fatal accidents. The morphometric and histological analysis of 420 neocortical fields (Nissl#staining,calbindin D28k, neuropeptide Y was performed using light and confocal microscopy.Results. We verified all main types of interneurons (Basket, Martinotti, and neurogliaform interneurons in neocortex based on the morphology of their bodies and dendritic processes in both groups. The number of calbindin- and NPY-positive neurons in the neocortex was similar in the control and in the postoperative period.However, calbindin- and NPY-immunopositive structure fields including neuronal cell bodies and their dendrites were significantly more represented in neocortex of patients from the main group. Maximum increase in common square in the relative areas of calbindin-immunopositive structures was observed 90 days after ischemia. The squares of NPY#immunopositive fields became larger seven days after resuscitation and remained increased on 90th day post-resuscitation.Conclusion. Our findings demonstrate an increase of calbindin and NPY expression in human neocortex after clinical death, which can be explained by a compensatory  eaction of undamaged inhibitory cortical interneurons directed to protectbrain from ischemia.

    Focal epithelial hyperplasia or Heck's disease, is a rare viral infection of the oral mucosa caused by human papillomavirus. The frequency of this disease varies widely from one geographic region to another. In Caucasians there have been only few cases reported. This paper reports a case of focal epithelial hyperplasia and demonstrates the association with HPV subtype 32 through polymerase chain reaction (PCR) and sequencing of PCR products. A 7-year-old Caucasian girl was admitted to our clinic for investigation of multiple oral mucosal lesions in the mouth. Lesion was excised under local anesthesia without any complication. The lesion was diagnosed as focal epithelial hyperplasia according to both clinical and histopathological features. Dental staff should be aware of these kind of lesions and histopathological examination together with a careful clinical observation should be carried out for a definitive diagnosis.

    An individualised care plan is described for a woman diagnosed with pneumonia, intubated, and on invasive mechanical ventilation, who was admitted to the Intensive Care Unit for extracorporeal membrane oxygenation (ECMO). A nursing care plan was designed based on Marjory Gordon functional patterns. The most important nursing diagnoses were prioritised, using a model of clinical reasoning model (Analysis of the current status) and NANDA taxonomy. A description is presented on, death anxiety, impaired gas exchange, decreased cardiac output, dysfunctional gastrointestinal motility, risk for disuse syndrome, infection risk, and bleeding risk. The principal objectives were: to reduce the fear of the family, achieve optimal respiratory and cardiovascular status, to maintain gastrointestinal function, to avoid immobility complications, and to reduce the risk of infection and bleeding. As regards activities performed: we gave family support; correct management of the mechanical ventilation airway, cardio-respiratory monitoring, skin and nutritional status; control of possible infections and bleeding (management of therapies, care of catheters…). A Likert's scale was used to evaluate the results, accomplishing all key performance indicators which were propose at the beginning. Individualised care plans with NNN taxonomy using the veno-venous ECMO have not been described. Other ECMO care plans have not used the same analysis model. This case can help nurses to take care of patients subjected to veno-venous ECMO treatment, although more cases are needed to standardise nursing care using NANDA taxonomy.

    A clinical study was conducted in 110 cases of subjective aniseikonia, a syndrome that is often neglected. After in practice summarizing the different distortions composing the phenomenon of aniseikonia, a description of the prototype apparatus used for the experiments is given: it is eikonometric stereo-projector the originality of which lies in the measuring system, constituted by the projected stereograms. Three parameters were studied: depth-perception, peerception threshold of anseiikonic disparity, and value of the found aniseikonia. The results are presented in relation to 3 groups of subjects: 14 emmetropic, 32 isometropic, and 64 anisometropic, 32 isometropic, and 64 anisometropic patients, including 24 monocular aphakic. The author shows the advantage of contact lens correction in the last cases: with an average of 3.5 p. cent, the found aniseikonia was always inferior to 6 p. cent and to the theorectical levels currently accepted. Finally, the phenomenon of "cortical malleability" arises in the adaptation of the patient to his optical correction and could regularly and progressively be increased.

    Full Text Available The incidence of bilateral testicular cancer is 5% in the total cohort of patients. Synchronous and metachronous testicular cancers are detected in 1-2 and 3% of cases, respectively. The standard treatment for testicular cancer is orchifuniculectomy and that for synchronous or metachronous cancer is organ-saving treatment, testectomy.The paper describes a clinical case of multiple primary metachronous testicular cancer. A 24-year-old patient underwent surgery (orchifuniculectomy and received 4 courses of BEP polychemotherapy for embryonal carcinoma of the left testicle at the P.A. Herzen Moscow Oncology Research Institute. After 55 months, a dynamic control examination diagnosed a 9-mm tumor in his single right testis that was thereafter resected. Its histological examination revealed embryonal carcinoma with solitary structures in the immature teratoma. Following 22 months, a control examination showed a recurrence of the disease, for which orchifuniculectomy of the single right testis, followed by hormone replacement therapy, was performed. The follow-up period was 80 months; no recurrence is now observed.

    To present case studies of a 36-year-old woman and a 73-year-old man who presented with the syndrome of acromegaly, and to provide primary care nurse practitioners (NPs) with the understanding of the clinical and laboratory features needed for early recognition and treatment of this fascinating disease. A comprehensive review of published literature on acromegaly is presented. The findings discussed include the history, physical examination, and diagnostic studies of two patients presenting in different ways. They both saw multiple healthcare providers, and had symptoms and signs eventually leading to the diagnosis of acromegaly. Acromegaly is the result of excessive amounts of growth hormone (GH) and insulin-like growth factor type 1 (IGF-1), almost always caused by a benign adenoma of the pituitary gland. This leads to coarse facial features, soft tissue swelling (including the tongue), enlargement of the hands and feet, respiratory problems, hypertension, diabetes mellitus, carpal tunnel syndrome, and osteoarthritis. Early recognition and appropriate referral can reverse some of the signs and symptoms over time, and lead to decreased mortality and a markedly improved quality of life. These cases exemplify the challenges faced by NPs and other healthcare providers in diagnosing patients with acromegaly. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

    Appendiceal mucocele as a cystic dilatation filled with mucinous material is a very rare disease of the appendix vermiformis. Its preoperative diagnosis is still acking behind common use of imaging techniques. Retrospective analysis of the patients with a pathological diagnosis of appendiceal mucocele with regard to clinical and imaging features. The study group included 14 patients with a mean age of 51 years (range from 17 to 82 years). Predominant symptoms were pain and feeling of fullness in the right iliac fossa in 9(64%) and 5 (36%) patients, respectively. For imaging purposes, use of computed tomography resulted in preoperative diagnosis of appendiceal mucocele in half of the patients(50%). 93% of the cases underwent appendectomy, and righth emicolectomy was performed in one patient (7%). Mucocele and cystadenoma were detected in 11 (79%) and 3 (21%)patients, respectively. Presence of acute appendicitis and coloncarcinoma were confirmed afterwards histologically in 4 (29%)and one (7%) patients, respectively. Despite the common use of imaging studies,preoperative diagnosis of appendiceal mucocele is still not possible in most of the cases. During surgical treatment,which is tailored according to imaging and intraoperative findings, precautionary measures to avoid intraperitoneal rupture and dissemination should be taken. Celsius.

    A 21-year-old girl arrived at our hospital with a short history of hirsutism, facial pletora, amenorrhea, progressive weight gain and hypertension. The clinically suspected Cushing syndrome was then confirmed through chemical pathology. In fact, the results from hemato-chemical exams were: 45.5 Ig/dl cortisol, a DHEA sulphate >8000 ng/ml, 7.2 pg/ml ACTH, 17OH-Progesterone 10.66 ng/ml, Delta-4 Androstenedione 5.2 ng/ml, UFC (Urine Free Cortisol) >1000 mg/24h, FSH 0.8 mUI/ml, LH < 0.1 mUI/ml, Prolactin 13, 17, estradiol 96 pg/ml, and a bonded hypokalaemia, K+ 2,4 mEq/L. The echogram of the complete abdomen reveals, near the superior pole of the left kidney, the presence of a solid mass, not independent from the pole itself about 9.5 centimetres long, diagnosis confirmed to the TC abdomen and pelvis too, with or without mdc. This removed mass resulted, from the histological exam, in an adrenal carcinoma with a general and trabecular structure. Primal adrenal tumours are responsible for about 10% of Cushing syndrome cases. They present an annual incidence of 0.5 - 2.0 cases per million of inhabitants. The prognosis of adrenal ca remains low, with 5 year survival rate for 38% of diagnosed patients.

    Background An eruption cyst (EC) is a benign, developmental cyst associated with a primary or permanent tooth. This paper presents 66 ECs in 53 patients who reported to 3 different centers in Turkey between 2014-2015. Material and Methods 53 patients (31 male, 22 female) with 66 ECs were diagnosed and treated over a 1-year period. The mean age of patients was 5.4 years (minimum 5 months, maximum 11 years). Clinical examination and periapical radiographs were used to establish diagnosis. Age, gender, site, history of trauma and type of treatment were recorded. Results Of the 66 ECs diagnosed in 53 patients, more than half (56.6%) were located in the maxilla, with the maxillary first primary molars the teeth most commonly associated with ECs (30.3%). Multiple ECs were diagnosed in 13 of the 53 patients. ECs had previously diagnosed in the primary dentition of 2 patients, 3 patients reported a history of trauma to primary teeth. In the majority of patients (46 cases, 86.8%), no treatment was provided, whereas surgical treatment was provided in the remaining 7 cases (13.2%). Conclusions Eruption cysts are usually asymptomatic and do not require treatment;. however, if the cyst is symptomatic, it should be treated with simple surgical excision.

    Schwannoma is a benign tumor that originates from the presence of Schwann cells of the peripheral nerves. They are usually asymptomatic, do not recur, and malignant transformation is rare. The preoperative diagnosis is often difficult, and although computed tomography and magnetic resonance imaging are very helpful, in the majority of cases, the diagnosis can only be made during surgery and by histological study. The immunohistochemistry reveals that the Schwannoma cells test positive for S-100 protein. We describe a clinical case of Schwannoma located in the palate of a 15-year-old patient. It is important to highlight that the Schwannoma is usually found in the head and neck, and rarely in the oral cavity. When it does occur in this area, it is more likely to be found in the tongue. Other locations in the oral cavity include: the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area, listed from most common to least common. There has been no sign of recurrence two years after surgery.

    BACKGROUND: Spinal muscular atrophy (SMA) is a kind of degenerative disease of nervous system. There are 4 types in clinic, especially types Ⅰ, Ⅱ and Ⅲ are common, and the researches on those 3 types are relative mature. Type Ⅳ is a kind of adult spinal muscular atrophy (ASMA), which has low incidence rate and is often misdiagnosed as amyotrophic lateral sclerosis, muscular dystrophy, cervical syndrome, or others.OBJECTIVE: To observe the clinical features of 46 ASMA patients and analyze the relationship between course and activity of daily living.DESIGN: Case analysis.SETTING: Departments of Neurology of the 81 Hospital of Chinese PLA, the Second Affiliated Hospital of Nanjing Medical College and General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: A total of 46 ASMA patients were selected from the Departments of Neurology of the 81Hospital of Chinese PLA, the Second Affiliated Hospital of Nanjing Medical College and General Hospital of Nanjing Military Area Command of Chinese PLA between April 1998 and January 2002. All patients were consentient. Among 46 cases, there were 37 males and 9 females with the mean age of 42 years. The patients' courses in all ranged from 6 months to 23 years, concretely, courses of 37 cases were less than or equal to 5 years, and those of 9 cases were more than or equal to 6 years.METHODS : ① All the 46 ASMA patients were asked to check blood sedimentation, anti O, serum creatinine,creatine, blood creatine phosphokinase (CPK) and muscular biopsy as early as possible. ② X-ray was used to measure plain film of cervical vertebra borderline film of cranium and neck at proximal end of upper limb of 25 cases and plain film of abdominal vertebra at proximal end of lower limb of 17 cases.③ Cerebrospinal fluid of lumbar puncture was checked on 42 cases, for routine examination, biochemical examination, and immunoglobulin examination. Electromyogram (EMG) was also examined to 42 cases. ④ Barthel index

    Full Text Available Parainfectous limbic encephalitis (PILE associated with viruses of the Herpesviridae family is one of the forms of chronic herpes encephalitis characterized by limbic system dysfunction and a prolonged course with frequent exacerbations. There are two types of the course of the disease: latent autoimmune limbic encephalitis (LE progressing to mesial temporal sclerosis and pseudotumorous granulomatous LE. The latter (inflammatory pseudotumor or granuloma is characterized by the formation of a polymorphic inflammatory infiltrate with the elements of fibrosis, necrosis, and a granulomatous reaction and by myofibroblast cells. This is a slowly growing benign pseudotumor that contains much more plasma cells than inflammatory ones. The diagnosis of pseudotumorous LE is difficult and requires the participation of a neurologist, an immunologist, an oncologist, and a neurosurgeon. Perfusion computed tomography, magnetic resonance imaging, and magnetic resonance spectroscopy give proof to the adequacy of the term inflammatory pseudotumor because it is histologically difficult to characterize the lesion as a tumor or inflammation. When a chronic lesion in the central nervous system is lately diagnosed, the prognosis of the disease may be poor and complicated by the development of resistant symptomatic focal epilepsy and emotional, volitional, and cognitive impairments. It was differentially diagnosed from brain tumors (astrocytic, oligodendroglial, and mixed gliomas, ependymal, neuronal, neuroglial, and embryonal tumors, meningiomas, cholesteatomas, dermoid cysts, teratomas, and cysts, other reactive and inflammatory processes (leukemic infiltrations, systemic lupus erythematosus, multiple sclerosis, encephalomyelitis, hypoparathyroidism, Addison's disease, vitamin A intoxication, and the long-term use of glucocorticoids and contraceptives. The authors describe a clinical case of the pseudotumorous course of chronic PILE in a 28-year-old woman

    Although compartment syndrome is a rare complication of total knee arthroplasty, it is one of the most devastating complications. It is defined as a situation of increased pressure within a closed osteofascial space that impairs the circulation and the functioning of the tissues inside this space, thereby leading to ischemia and tissue dysfunction. Here, a clinical case of a patient who was followed up in orthopedic outpatient consultations due to right gonarthrosis is presented. The patient had a history of arthroscopic meniscectomy and presented knee flexion of 10° before the operation, which consisted of total arthroplasty of the right knee. The operation seemed to be free from intercurrences, but the patient evolved with compartment syndrome of the ipsilateral leg after the operation. Since compartment syndrome is a true surgical emergency, early recognition and treatment of this condition through fasciotomy is crucial in order to avoid amputation, limb dysfunction, kidney failure and death. However, it may be difficult to make the diagnosis and cases may not be recognized if the cause of compartment syndrome is unusual or if the patient is under epidural analgesia and/or peripheral nerve block, which thus camouflages the main warning sign, i.e. disproportional pain. In addition, edema of the limb that underwent the intervention is common after total knee arthroplasty operations. This study presents a review of the literature and signals that the possible rarity of cases is probably due to failure to recognize this condition in a timely manner and to placing these patients in other diagnostic groups that are less likely, such as neuropraxia caused by using a tourniquet or peripheral nerve injury.

    1992-12-01

    Schwannoma or neurilemmoma and neurofibroma are two tumors of the peripheral nerves originating in the nerve sheaths. Schwannoma account for just over 1% of benign tumors reported in the oral cavity. The tongue is unanimously considered the most frequent site at this level; however, the tip is the least affected part of the organ. The case of schwannoma reported here is the third observed with a lingual localization in 18 years by the Division of Maxillo-Facial Surgery of The Odontostomatological Clinic of the University of Turin. The case is of interest due the rarity of this pathology and the presence of non-significant symptoms for a presumed initial diagnosis. CASE REPORT. A 21-year-old woman was referred to our attention following the appearance two years earlier of a slowly growing swelling on the tip of the tongue. The patient complained of the fastidious presence, disturbance to mastication and phonation and occasional paresthesia of the tip of the tongue. The small mass, which was clearly evident on examination, was covered with normal mucosa. On palpation it had a hard-elastic consistency; it was slightly painful, smooth and partial mobile on surrounding levels. The patient underwent the surgical removal of the neoplasia under anesthesia. The mass was well capsulated and a good cleavage plane was easily found. The neoformation was yellowy grey, oval bean-shaped, measuring 1.9 x 1.3 x 1.1 cm. The histological diagnosis, confirmed by immunohistochemical tests, was benign Antoni's, type A schwannoma. The postoperative period was good an there was no recidivation during the course of a one-year follow-up. DISCUSSION AND CONCLUSIONS. Benign schwannoma, which are relatively rare in the oral cavity, represent a pathology which are often not taken into account during clinical practice. Symptoms which take the form of slight hypoesthesia and vague paresthesia may lead to the suspected diagnosis of this type of neoplasia. The final diagnosis is always made after a

    Full Text Available Abstract This paper highlights the need for carriers to be followed up by health professionals who understand the complexities of the BRCA syndrome. A BRCA carrier clinic has been established in London and regular follow up is an essential part of the care for families. An open door policy has been set up for patients who may meet or telephone the cancer genetic nurse specialist for support and care at any time. An example of the follow up work is discussed in the format of a case of a young woman with a BRCA1 alteration who developed a primary peritoneal cancer following prophylactic oophorectomy. This case illustrates the work of the multi-disciplinary team caring for BRCA carriers.

    Full Text Available True placenta accreta is the attachment of chorionic villi to the myometrium, possibly penetrating into the thickness of the myometrium and its outside, including through the serous tunic. The main current diagnostic techniques are considered to be ultrasonography, laboratory diagnosis (elevated human chorionic gonadotropin and placental lactogen levels, and clinical data (pain and vaginal discharge. Magnetic resonance imaging is deemed to be an adjuvant technique. By using a clinical example, this paper considers the capabilities of magnetic resonance imaging to diagnose this abnormality and to choose a right treatment policy. The abnormality is compared with the conditions (trophoblastic tumor and myoma with lysis that are similar in their diagnosis and magnetic resonance pattern. The disorder in question is rather rare and its detailed consideration, determination of the capabilities of various techniques, and comparison with externally similar cases areimportant for the development of diagnostic opportunities.

    Full Text Available Anthrax, a zoonotic illness of herbivorous animals has caused epidemics in livestock and in man since antiquity. In India, the disease continues to be endemic, resulting in a few sporadic cases and outbreaks in human population. Such an outbreak was noted at our institute. Clinical and laboratory data of 15 cases of cutaneous anthrax recorded between July 1998 to June 2000 at the Department of Dermatology and STD. JIPMER hospital, Pondicherry was reviewed. There were 8 males and 7 females in our series of 15, with a mean age of 20.3 years (range 11 months to 56 years. The children (10 outnumbered the adults (5. In most of the cases (9 there was history of death of cattle, sheep or goat in the house or in the neighbourhood. The commonest site of cutaneous anthrax was face (7 cases. Regional lymphadenitis occurred in one case and systemic features like fever in four cases. Majority of our cases responded favourably to crystalline penicillin. Smear taken from the vesicle fluid and eschar demonstrated typical large and thick Gram positive bacilli singly or in short chains. The organism could be cultured from cutaneous lesion in six cases only and blood culture was positive for Bacillus anthracis in one case. Cutaneous anthrax is the commonest form of human anthrax. There is increasing evidence to suggest that files and mosquitoes play a role in the transmission of Bacillus anthracis to human beings. Since 20% of untreated cases of cutaneous anthrax develop bacteraemia which leads to rapid death, it is important that the disease is recognized and treated earnestly.

    "Water problems" are fundamentally human problems -- aligning water quality and quantity with human aspirations. In the U.S., however, the few ongoing efforts to repeatedly observe humans in relation to water at large scale are disjointed both with each other and with observing systems for water quality and quantity. This presentation argues for the systematic, coordinated, and on-going collection of primary data on humans, spanning beliefs, perceptions, behaviors, and institutions, alongside the water environments in which they are embedded. Such an enterprise would advance not only water science and related policy and management decisions, but also generate basic insights into human cognition, decision making, and institutional development as they relate to the science of sustainability. In support of this argument, two types of original analyses are presented. First, two case studies using existing data sets illustrate methodological issues involved in integrating natural system data with social data at large scale: one concerns the influence of water quality conditions on personal efforts to conserve water and contribute financially to environmental protection; the other explores relationships between recreation behavior and water quality. Both case studies show how methodological differences between data programs seriously undercut the potential to draw inference about human responses to water quality while also illustrating the scientific potential that could be realized from linking human and scientific surveys of the water environment. Second, the results of a survey of water scientists concerning important scientific and policy questions around humans and water provide insight into data collection priorities for a coordinated program of observation.

    Objective: To review the clinical characteristics, treatment and prognoses of abdominal wall endometriosis(AWE).Methods: A retrospective study of 101 cases of AWE from 1992 to 2005 at Obstetric and Gynecologic Department of Peking Union Medical College Hospital was performed. Ninety-eight patients had a history of caesarean section. The mean age of the patients was (33.3±4.8) years and the average size of the mass was 1.5 cm. Abdominal wall mass associated pain during the menstrual cycle was noticed in 89.8% of the patients. The occurrence of AWE after caesarean section was 0.05% at our hospital. In patients without pelvic endometriosis or adenomyosis, 20.5% were presented with high CA125 >35 U/ml and the highest one was 93.4 U/ml. 92.1% of patients were diagnosed before surgery. 4 patients were administrated first in General Surgical Department with painless abdominal mass. Medication was adopted in 16 cases pre-operatively and 14 cases post-operatively.Results: The mean size of the resected mass was 4.2 cm, significantly larger than the estimation with palpation or ultrasonography, which was 0.8-1.2 cm (P=0.006, P<0.001). Pelvic endometriosis or adenomyosis was detected during the operation in 13 patients. One patient was diagnosed as atypical endometriosis by pathological examination in the beginning but transformed to be sarcoma finally. Ten patients recurred after surgery. 2 of them received medication and 5 of them received second operation.Conclusions: Ultrasonography can be used to evaluate the size of the mass and the infiltrative scope pre-operation. The serum CA125 is not specific for diagnosis of AWE. Complete eradication of the lesion with at least 1 cm beyond the edge of the mass is recommended as the primary treatment. Eradication should be considered also in recurrent cases. It may transform to malignant lesions after multiple recurrence.

  7. A Finger Amputation Case Caused by Human Bite

    Full Text Available Bite is a type of wound created with animal or human teeth. Bite wounds created by humans are encountered in situations as fighting, rape, murder and child abuse. Bite marks are usually observed on arms, neck, breasts, body, cheeks and legs. The teeth may penetrate to skin on the areas where bone or cartilage tissue lies underneath skin, and tissue loss may occur. Auricles are most frequent regions that occur tissue loss with bites. Finger amputation occurring with human bite is extremely rare. The case presented in this paper is a 28 years old man. In his medical history, the 3rd finger of his left hand was bitten during a fight two months ago. One centimeter shortness at the end point of the distal phalanx of the left 3rd finger because of tissue loss was found in the examination. In his left hand radiograph, bone defect at the middle part of the distal phalanx of 3rd finger was determined. The case has been discussed by comparing similar cases rarely reported in the literature. Keywords: Forensic medicine, human bite, amputation

  8. A review on the clinical spectrum and natural history of human influenza.

    2012-10-01

    The objective of this review is to provide updated information on the clinical spectrum and natural history of human influenza, including risk factors for severe disease, and to identify the knowledge gap in this area. We searched the MEDLINE database of the recent literature for the period January 2009 to August 17, 2011 with regard to the abovementioned aspects of human influenza, focusing on A(H1N1)pdm09 and seasonal influenza. The clinical spectrum and outcomes of cases of A(H1N1)pdm09 influenza have been mild and rather indistinguishable from those of seasonal influenza. Sporadic cases covering a wide range of neurological complications have been reported. Underlying predisposing conditions considered to be high-risk for A(H1N1)pdm09 infections are generally similar to those of seasonal influenza, but with two additional risk groups: pregnant women and the morbidly obese. Co-infections with bacteria and D222/N variants or 225G substitution of the viral genome have also been reported to be significant factors associated with the severity of disease. The current knowledge gap includes: (1) a lack of clarification regarding the relatively greater severity of the Mexican A(H1N1)pdm09 influenza outbreak in the early phase of the pandemic; (2) insufficient data on the clinical impact, risk factors, and outcomes of human infections caused by resistant strains of influenza; and (3) insufficient data from less developed countries that would enable them to prioritize strategies for influenza prevention and control. Clinical features and risk factors of A(H1N1)pdm09 are comparable to those of seasonal influenza. Emerging risk factors for severe disease with A(H1N1)pdm09 include morbid obesity, pregnancy, bacterial co-infections, and D222/N variants or 225G substitution of the viral genome.

    Despite increased efforts to control and ultimately eradicate human malaria, Plasmodium ovale malaria is for the most part outside the focus of research or public health programmes. Importantly, the understanding of P. ovale-nowadays regarded as the two distinct species P. ovale wallikeri and P. ovale curtisi-largely stems from case reports and case series lacking study designs providing high quality evidence. Consecutively, there is a lack of systematic evaluation of the clinical presentation, appropriate treatment and relapse characteristics of P. ovale malaria. The aim of this systematic review is to provide a systematic appraisal of the current evidence for severe manifestations, relapse characteristics and treatment options for human P. ovale malaria. This systematic review was performed according to the PRISMA guidelines and registered in the international prospective register for systematic reviews (PROSPERO 2016:CRD42016039214). P. ovale mono-infection was a strict inclusion criterion. Of 3454 articles identified by the literature search, 33 articles published between 1922 and 2015 met the inclusion criteria. These articles did not include randomized controlled trials. Five prospective uncontrolled clinical trials were performed on a total of 58 participants. P. ovale was sensitive to all tested drugs within the follow-up periods and on interpretable in vitro assays. Since its first description in 1922, only 18 relapsing cases of P. ovale with a total of 28 relapse events were identified in the scientific literature. There was however no molecular evidence for a causal relationship between dormant liver stages and subsequent relapses. A total of 22 severe cases of P. ovale malaria were published out of which five were fatal. Additionally, two cases of congenital P. ovale malaria were reported. Current knowledge of P. ovale malaria is based on small trials with minor impact, case reports and clinical observations. This systematic review highlights that P

    Full Text Available Placental site trophoblastic tumor (PSTT is a very rare variant of gestational trophoblastic tumor. It can occur after normal termination of pregnancy or spontaneous abortion and ectopic or molar pregnancy. There is a wide range of clinical manifestations from a benign condition to an aggressive disease with fatal outcome. One of the most important characteristics of PSTT, unlike other forms of gestational trophoblastic diseases (GTD is the presence of low beta-subunit of human chorionic gonadotropin (β-hCG levels because it is a neoplastic proliferation of intermediate trophoblastic cells. However, human placental lactogen (hPL is increased on histologic section and in the serum of patients too. We present a case of PSTT and discuss the differential diagnosis in order to further familiarize physicians with the diagnosis and treatment of this disease. It has a varied clinical spectrum and usually presents with irregular vaginal bleeding or amenorrhea. Diagnosis is confirmed by dilatation and curettage (D and C and hysterectomy. Because chemotherapy is not effective, surgery is the cornerstone of treatment. This case is presented because it is a rare neoplasm with different treatments and it should be differentiated from molar pregnancy.

    A 17-year-old female patient presented with the clinical features of an acute appendicitis. During laparoscopic exploration a macroscopically normal appendix was found. Since there were no intra-abdominal abnormalities found, the appendix was resected. Anatomopathology demonstrated Enterobius vermicularis, a pinworm infecting only humans, and mostly living in the caecum. This parasite is responsible for possibly the most common helminthic infection in the developed world. Its role in the pathogenesis of acute appendicitis is controversial, but more recent studies indicate a stronger association between enterobiasis and appendicitis. Often, enterobius mimics appendicitis by obstructing the lumen of the appendix, thereby causing appendiceal colic. This case report stresses the importance of microscopic examination of all appendectomy resection specimens. In case of enterobius infestation, systemic therapy of patient and family is necessary.

    Full Text Available Human bocavirus (HBoV is a major etiology of lower respiratory tract infection (LRTI in young children. We tested 149 patients admitted to King Fahd Hospital of the University with diagnosis of LRTI. Viremia caused by the different studied viruses was detected in 31.5% of the total cases by Real-time Polymerase chain reaction. We report five patients who were positive for HBoV in serum samples. Clinical presentation ranged from mild to severe disease as one of them required admission to intensive care unit. Wheezing was a striking feature in most of our patients, but fever was not a consistent finding.

    Here we report a case of carbapenem resistance in a human clinical isolate that was found to be closely related to the newly described environmental species Acinetobacter indicus. This strain harboured the blaOXA-23 carbapenemase gene located on a conjugative plasmid. Partial sequencing of 16S rDNA and rpoB genes, together with matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF) analysis, showed that this strain was distantly related to the Acinetobacter baumannii-calcoaceticus complex and was closely related to A. indicus.

    Through the retrospective analysis of the clinical data in 14 cases of invasive fungal rhinosinusitis (IFRS), the clinical characteristics, diagnosis and treatment of this disease were evaluated. Fourteen clinically confirmed cases of IFRS since January 2008 to October 2015 were evaluated.collected, the clinical features, diagnosis, treatment and prognosis were analyzed to obtain a more comprehensive understanding for clinical reference. Fourteen patients were confirmed by pathological examination as IFRS, including 9 cases of aspergillus, 4 cases of mucor, and 1 case of rhinocerebral zygomycosis; including 5 cases of acute IFRS, 9 cases of chronic IFRS. All patients were treated with endoscopic surgery and intravenous antifungal therapy. Nine cases of chronic IFRS (including 1 case of mucor, 7 cases of aspergillus and 1 case of rhinocerebral zygomycosis) were cured, but the vision loss, diplopia or blindness, hard palate perforation remained. Five cases of acute IFRS included 3 cases of mucor and 2 cases of aspergillus. Among the 3 cases of mucor, 2 cases were died and 1 case was cured. Among the 2 cases of aspergillus, 1 patient was cured and the other patient died of electrolyte disorder after discharge from hospital. Patients with IFRS usually have diabetes. After the active surgical cleaning of lesion tissue and the systematic antifungal treatment with adequate dosage, these patients would have a better result. IFRS caused by mucor is ofen dangerous.

    Full Text Available Introduction: The frontal osteomyelitis is a complication of rhinosinusitis which can evolve to acute or chronicle. There is inflammatory reaction by the increasing of intraosseous pressure, ischemia and local necrosis, leading to bone abscess formation. There is no drainage, it will occur detachment of the periosteum, soft tissue invasion and worsening of ischemia with subsequent bone sequestration. Method: Case report of an inpatient in an emergency service of another institution by the complication of rhinosinusitis who was referred to the Otorhinolaryngology Service of University Hospital Professor Edgard Santos of Federal University of Bahia. Case Report: Male patient, 16 years-old, presented himself to the ER of another institution with cephalea, vomits and fever which evolved to periorbital edema and frontal to the left, moving to palpebral fluctuation and frontal. Subjected to frontal and palpebral abscess drainage, with broad-spectrum antibiotic therapy with no improvement. He was referred to our service keeping edema and fluctuation in region frontal and light edema in left periorbital region. The nasal endoscopy showed edema in meatus to the left and the computerized tomography showed fronto-ethmoid sinusitis to the left and signs of frontal osteomyelitis with bone sequestration and epidural empyema. Subjected to sinasal endoscopy surgery, external Access or removal of the frontal one affected and epidural empyema drainage. Evolved to the remission of the disease. Final Considerations: Failure in the diagnosis and rhinosinusitis complication treatment can lead to sequalae and fatal complications. The diagnosis of the frontal osteomyelitis is confirmed by the clinical suspicion and confirmed by radiological examination. The surgery is indicated when the evolution is insidious, there is bone sequestration and intracranial complications.

    Full Text Available Multifocal malignant tumors (MMT represent a comprehensive and multifaceted problem of clinical oncology.Today, as far as observations are accumulated, there are attempts to determine a real incidence rate of multifocal tumors. Research of MMT problem becomes more and more actual and significant in oncology. Several dozen thousands of MMT observations have been described all over the world for the recent 30 years. There is a stable trend towards the increase of the number of patients with such pathology. This is primarily concerned with the improvement of diagnostics, medical treatment and increased expectation of life.The increase in incidence of MMT is due to such factors as increased average expectation of life, increased intensity of carcinogenic effects, urbanization, accumulation of hereditary loading and improved diagnostics of oncologic diseases. Detection and record of such pathology are based first on detection of simultaneous tumors, second – on diagnostics of tumor and retrospective determination according to life record data of the first neoplasm, third – on determination of further tumor at regular follow-up, which requires prolonged and high quality examination of the patients.MMT most commonly develop in patients elder than 50 y. o., even in elder age in men than in women. The article describes a case of bilateral breast cancer in man. Clinicopathologic and immunohistochemical characteristics of the tumor were studied, the genetic polymorphisms were investigated by the method of polymerase chain reaction, associated with the risk of breast cancer development, genetic analysis of BRCA1 and BRCA2, blood cancer markers was done. Full equivalence of clinicopathologic and biological properties of tumor of the right and left mammae, witnessing the common etiology and pathogenesis of neoplastic process, was established. Each case of bilateral breast cancer in men shall be studied with particular care and referred in international

    Subclinical hypothyroidism can be defined as an asymptomatic state in which a reduction in thyroid activity has been compensated by an increased TSH output to maintain an euthyroid state. We analysed clinical features, laboratory data, and pathologic findings in 39 cases of subclinical hypothyroidism who were diagnosed at the Dept. of Internal Medicine, Chungnam National University Hospital from Aug. 1984 to June, 1985. 1) The age distribution was from sixteen to sixty-nine and mean age was 34.8. Peak incidence was in the 4th decade and 3rd, 5th, 6th decade in order. 2) The sex distribution showed female preponderance with a ratio of 18.5 to 1. 3) The major presenting manifestations were nonspecific ones such as fatigue, indigestion, and anorexia. 4) Physical examination revealed diffuse goiter in 47.6%. Major abnormalities were no gross abnormality (30.9%), nodular goiter and facial edema. 5) There was no significant difference of the basal serum T3 and T4 concentrations between subclinical hypothyroidism and normal controls (p>0.05). 6) The basal serum TSH concentration of subclinical hypothyroidism (32.61+-14.95 muU/ml) was significantly higher than that of normal controls (3.92+-1.05 muU/ml) (p<0.005). 7) Microsomal antibody was detected in 80.6% and thyroglobulin antibody was detected in 30%. 8) The pathologic findings in 26 cases revealed Hashimoto's thyroiditis in 76.9% (lymphocytic type, 34.6%; oxyphilic type, 26.9%; fibrotic type, 15.4%). The others were adenomatous goiter (15.4%), adenomatous carcinoma (3.8%) and subacute thyroiditis (3.8%).

    Full Text Available Objectives: We are presenting 20 cases of the intriguing clinico-electromyographic entity, now considered a potassium channel disorder, Neuromyotonia. Our experience with the clinical manifestations, underlying abnormalities and response to various therapies is documented. Materials and Methods: Patients with diffuse pain or undulating muscle movements, with or without stiffness were sent for electromyographic and further studies. Patients with "neuromyotonic discharges" were included after exclusion of hypocalcaemia. Results: Our cases included 19 males and one female of age group 15 to 52 years, the majority being between 30 to 45 years. Undulating movements were seen in 19, of which two had focal twitching. Muscle stiffness was a complaint in five; pain was the chief presenting complaint of 19, which started in the calf in all. Irritability, insomnia and a peculiar worried pinched face were present in 12 patients. CSF was abnormal with mildly raised protein in eight. Curiously, 11 of these patients had taken ayurvedic treatment for various complaints in the preceding one month. Bell′s palsy was associated in four, peripheral neuropathy in two and residual poliomyelitis in two. Electromyographic evidence of spontaneous activity in the form of "neuromyotonic discharges" was seen in all. Antibodies to voltage gated potassium channels was tested in one patient and was positive (titer was 1028 pM. Membrane stabilizers (e.g., phenytoin sodium in our experience did not provide adequate rapid relief; we tried high-dose intravenous Methylprednisolone in 19 with significant amelioration of complaints. One patient was offered intravenous immunoglobulin, to which he responded. Conclusions: Neuromyotonia is a heterogeneous condition and can present in varied ways including diffuse nonspecific pain. This uncommon condition is potentially treatable and can be picked up with high index of suspicion.

  20. Molecular identification of nocardia isolates from clinical samples and an overview of human nocardiosis in Brazil.

    Directory of Open Access Journals (Sweden)

    Paulo Victor Pereira Baio

    Full Text Available BACKGROUND: Nocardia sp. causes a variety of clinical presentations. The incidence of nocardiosis varies geographically according to several factors, such as the prevalence of HIV infections, transplants, neoplastic and rheumatic diseases, as well as climate, socio-economic conditions and laboratory procedures for Nocardia detection and identification. In Brazil the paucity of clinical reports of Nocardia infections suggests that this genus may be underestimated as a cause of human diseases and/or either neglected or misidentified in laboratory specimens. Accurate identification of Nocardia species has become increasingly important for clinical and epidemiological investigations. In this study, seven clinical Nocardia isolates were identified by multilocus sequence analysis (MLSA and their antimicrobial susceptibility was also determined. Most Nocardia isolates were associated to pulmonary disease. METHODOLOGY/PRINCIPAL FINDINGS: The majority of Brazilian human isolates in cases reported in literature were identified as Nocardia sp. Molecular characterization was used for species identification of Nocardia nova, Nocardia cyriacigeorgica, Nocardia asiatica and Nocardia exalbida/gamkensis. Data indicated that molecular analysis provided a different Nocardia speciation than the initial biochemical identification for most Brazilian isolates. All Nocardia isolates showed susceptibility to trimethoprim-sulfamethoxazole, the antimicrobial of choice in the treatment nocardiosis. N. nova isolated from different clinical specimens from one patient showed identical antimicrobial susceptibility patterns and two distinct clones. CONCLUSIONS/SIGNIFICANCE: Although Brazil is the world's fifth-largest country in terms of land mass and population, pulmonary, extrapulmonary and systemic forms of nocardiosis were reported in only 6 of the 26 Brazilian states from 1970 to 2013. A least 33.8% of these 46 cases of nocardiosis proved fatal. Interestingly, coinfection

    Thrombopoietin (TPO) is primarily produced by hepatocytes and regulates the production and differentiation of megakaryocytes and platelets in the bone marrow. The endogenous TPO level is increased when the megakaryocyte count is low, and high in aplastic anaemia and after myeloablative chemotherapy. TPO is cloned and manufactured by a recombinant technique for clinical use. Treatment with recombinant human TPO (rhTPO) after intensive chemotherapy may reduce the need for platelet transfusions. Administration of granulocyte colony-stimulating factor in combination with rhTPO has enhanced the mobilisation and harvest product of haematopoietic stem cells. Whether rhTPO is effective in the treatment of the myelodysplastic syndrome, aplastic anaemia, and other conditions with bone marrow insufficiency (including AIDS) is not yet known. In liver cirrhosis, the endogenous TPO level rapidly increases after liver transplantation. Accordingly, substitution of rhTPO may be indicated in advanced liver failure complicated by thrombocytopenia and bleeding.

    By modulating hepcidin production, an organism controls intestinal iron absorption, iron uptake and mobilization from stores to meet body iron need. In recent years there has been important advancement in our knowledge of hepcidin regulation that also has implications for understanding the physiopathology of some human disorders. Since the discovery of hepcidin and the demonstration of its pivotal role in iron homeostasis, there has been a substantial interest in developing a reliable assay of the hormone in biological fluids. Measurement of hepcidin in biological fluids can improve our understanding of iron diseases and be a useful tool for diagnosis and clinical management of these disorders. We reviewed the literature and our own research on hepcidin to give an updated status of the situation in this rapidly evolving field.

    Full Text Available After last year’s analysis regarding the European Union’s commitment to fight against the human beings trafficking, we have considered to further explore the human beings trafficking approach in the European Court of Human Rights case-law, the most developped regional jurisdiction on human rights. Surprisingly, the European Convention for the Protection of Human Rights and Fundamental Freedoms does not make an express reference to the human beings trafficking. However, we have to bear in mind that the Convention is a living instrument, its interpretation being made in the light of the present-day conditions. Thus, taking into consideration the global threat of this phenomenon, it is more obvious than ever that the Convention could not neglect this issue.

    2009-01-01

    Full Text Available Human granulocytic anaplasmosis (HGA is a tick-borne rickettsial infection of peripheral blood neutrophils caused by Anaplasma phagocytophilum. While this infection is increasingly recognized as endemic throughout much of the United States, no Canadian cases have been previously described, despite the agent being identified in Canadian ticks. Herein we present a case of HGA acquired in an urban Alberta centre. Canadian physicians must be aware of the possibility of tick-borne rickettsial diseases as etiology of fever in individuals presenting with leukopenia/lymphopenia, thrombocytopenia and elevated transaminases during periods of tick activity. Prompt recognition and treatment are important in minimizing resultant morbidity and mortality.

Canadian physicians must be aware of the possibility of tick-borne rickettsial diseases as etiology of fever in individuals presenting with leukopenia/lymphopenia, thrombocytopenia and elevated transaminases during periods of tick activity. Prompt recognition and treatment are important in minimizing resultant morbidity and mortality.

    To summarize and analyze the clinical characteristics and treatment of limbic encephalitis, in order to provide the basis for clinical work. We retrospectively analyzed the clinical characteristics, magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) and self immune antibody results of 22 patients with limbic encephalitis in Zheng zhou people's Hospital from March 2013 to May 2014. 22 cases of patients with psychiatric disturbance, such as hallucinations being typical clinical manifestations: Memory decline in 18 cases: Seizures in 13 patients: Altered level of consciousness in 10 cases; Movement disorders in 7 cases and 9 cases with febrile.14 cases have relieved after treating with antiviral and immunosuppressive therapy, 5 cases left memory decline, 2 patients left overwhelmingly excited, 1 cases of seizures. The clinical symptoms of patients with limbic encephalitis are complicated changeable and unspecific. so earlier diagnosis and treatment are very important for the prognosis of patients.

    Clinical ethics has been developing in paediatric healthcare for several decades. However, information about how paediatricians use clinical ethics case consultation services is extremely limited. In this project, we analysed a large set of case records from the clinical ethics service of one paediatric hospital in Australia. We applied a paediatric-specific typology to the case referrals, based on the triadic doctor-patient-parent relationship. We reviewed the 184 cases referred to the service in the period 2005-2014, noting features including the type of case, the referring department(s) and the patient's age at referral. The two most common types of referral involved clinician uncertainty about the appropriate care pathway for the child (26% of total referrals) and situations where the child's parents disagreed with the doctors' recommendations for the child's care (22% of total referrals). Referrals came from 28 different departments. Cancer, cardiology/cardiac surgery and general medicine referred the highest numbers of cases. The most common patient age groups were children under 1, and 14-15 years old. For three controversial areas of paediatric healthcare, clinicians had initiated processes of routine review of cases by the clinical ethics service. These insights into the way in which one very active paediatric clinical ethics service is used further our understanding of the work of paediatric clinical ethics, particularly the kinds of ethically challenging cases that paediatricians view as appropriate to refer for clinical ethics support.

  8. The global governance of human cloning: the case of UNESCO

    Since Dolly the Sheep was cloned in 1996, the question of whether human reproductive cloning should be banned or pursued has been the subject of international debate. Feelings run strong on both sides. In 2005, the United Nations adopted its Declaration on Human Cloning to try to deal with the issue. The declaration is ambiguously worded, prohibiting “all forms of human cloning inasmuch as they are incompatible with human dignity and the protection of human life”. It received only ambivalent support from UN member states. Given this unsatisfactory outcome, in 2008 UNESCO (the United Nations Educational, Scientific and Cultural Organization) set up a Working Group to investigate the possibility of a legally binding convention to ban human reproductive cloning. The Working Group was made up of members of the International Bioethics Committee, established in 1993 as part of UNESCO’s Bioethics Programme. It found that the lack of clarity in international law is unhelpful for those states yet to formulate national regulations or policies on human cloning. Despite this, member states of UNESCO resisted the idea of a convention for several years. This changed in 2015, but there has been no practical progress on the issue. Drawing on official records and first-hand observations at bioethics meetings, this article examines the human cloning debate at UNESCO from 2008 onwards, thus building on and advancing current scholarship by applying recent ideas on global governance to an empirical case. It concludes that, although human reproductive cloning is a challenging subject, establishing a robust global governance framework in this area may be possible via an alternative deliberative format, based on knowledge sharing and feasibility testing rather than the interest-based bargaining that is common to intergovernmental organizations and involving a wide range of stakeholders. This article is published as part of a collection on global governance.

    Focal epithelial hyperplasia (FEH), or Heck's disease, is a benign proliferative viral infection of the oral mucosa that is related to Human Papil-lomavirus (HPV), mainly subtypes 13 and 32. Although this condition is known to exist in numerous populations and ethnic groups, the reported cases among Caucasians are relatively rare. It presents as asymptomatic papules or nodules on the oral mucosa, gingiva, tongue, and lips. Histopathologically, it is characterized by parakeratosis, epithelial hyperplasia, focal acanthosis, fusion, and horizontal outgrowth of epithelial ridges and the cells named mitozoids. The purpose of this case report was to present 3 cases of focal epithelial hyperplasia in a pediatric age group. Histopathological and clinical features of cases are discussed and DNA sequencing analysis is reported in which HPV 13, HPV 32, and HPV 11 genomes are detected.

    In his discussion of this case study, the author indicates that human beings are not merely machines who use rules. Thus, more focus needs to be put on studying decision making situations and their contexts. Decision theory (both normative and descriptive) and contextual psychological approaches may offer tools to cope with operator decision making. Further an ideal decision space needs to be defined for operators. The case study specifically addressed a loss of feedwater scenario and the various operator decisions that were involved in that scenario. It was concluded from this particular study that there are significant differences in the crew decision behaviours that are not explained by process variables. Through use of evidence from simulator tests with expert judgement, an approach to estimate probabilities has been developed. The modelling approach presented in this discussion is an extension of current HRA paradigms, but a natural one since all human beings make decisions.

    Full Text Available There has been growing concern and search for esthetic beauty and harmony over the last few years. This concern does not form part ofadults’ lives only, but also of children’s. Among the substances used for bleaching dental structures, the most outstanding are those whoseactive principle is hydrogen peroxide-based . The present study reports a clinical case of a 4-year-old girl that suffered trauma of tooth 61 with consequent color alteration, but with no alteration in pulp vitality. The main complaint by the patient and her guardians concerned esthetics, therefore external dental bleaching was performed, using Opalescence Xtra® (Ultradent, in two sessions with an interval of one month between them. External in office bleaching was the treatment of choice, due to the tooth vitality, patient’s age and presence of only one darkened tooth. After the bleaching treatments an improvement in the darkening was observed, and both the child and her guardians were satisfied with the esthetic result.

    Postradiation sarcoma of bone is an uncommon but serious sequela of radiation therapy. Seventy-eight Mayo Clinic patients have been treated for sarcomas arising in irradiated bones. They received their initial radiotherapy for a wide variety of nonneoplastic and neoplastic conditions, both benign and malignant. Thirty-five sarcomas arose in bone that was normal at the time of radiotherapy, and 43 arose in irradiated preexisting osseous lesions. The latent period between radiotherapy and diagnosis of sarcoma averaged 14.3 years. Ninety percent of the postradiation sarcomas were either osteosarcomas or fibrosarcomas; chondrosarcoma, malignant (fibrous) histiocytoma, malignant lymphoma, Ewing's tumor, and metastasizing chondroblastoma also occurred. Prompt radical surgery, when feasible, is usually the treatment of choice for the sarcoma. About 30% of patients with sarcomas of the extremities or craniofacial bones survived 5 years without recurrence; there were no disease-free survivors among patients with tumors of the vertebral column, pelvis, or shoulder girdle. The low risk of sarcoma following radiotherapy for the treatment of cancer should not be a contraindication to its use in these patients; however, radiation therapy for benign bone tumors should be reserved for lesions that are not amenable to surgical treatment. An unusual case is also reported herein in which a fibrosarcoma was discovered in the humerus of a patient who had received radiotherapy 55 years previously for a verified osteosarcoma in the same site.

    Sheehan syndrome (SS) or post-partum pituitary necrosis is a pituitary insufficiency secondary to excessive post-partum blood losses. SS is a very significant cause of maternal morbidity and mortality in developing countries although it is a rarity in developed countries in which obstetrical care has been improved. In this study, we reviewed 20 cases retrospectively who were diagnosed as SS in our clinic. The patients aged 40 to 65 years with a mean age of 51.12 +/- 9.44 years (mean +/- SD). Time to make a definitive diagnosis of the disease ranged between 5 and 25 years with a mean of 16.35 +/- 4.74 years. Three of our patient (15%) had a previous diagnosis of SS. Three patients (15%) were referred to emergency service for hypoglycemia, three patients (15%) for hypothyroidism and one patient (5%) for hyponatremia. Dynamic examination of the pituitary revealed GH, Prolactin, FSH, TSH and ACTH insufficiency in all of the patients. One of our patients had a sufficient LH response to LHRH challenge. All of the patients were imaged with pituitary MRI. Eleven patients had empty sella and 9 patients had partial empty sella. SS is still a common problem in our country, especially in rural areas. Considering the duration of disease, important delays occur in diagnosis and treatment of the disease.

    2012-09-01

    Full Text Available Abstract Dendritic cells (DCs are critically involved in inducing either immunity or tolerance. During the last decades efforts have been devoted to the development of ad hoc methods to manipulate DCs in vitro to enhance or stabilize their tolerogenic properties. Addition of IL-10 during monocyte-derived DC differentiation allows the induction of DC-10, a subset of human tolerogenic DCs characterized by high IL-10/IL-12 ratio and co-expression of high levels of the tolerogenic molecules HLA-G and immunoglobulin-like transcript 4. DC-10 are potent inducers of adaptive type 1 regulatory T cells, well known to promote and maintain peripheral tolerance. In this review we provide an in-depth comparison of the phenotype and mechanisms of suppression mediated by DC-10 and other known regulatory antigen-presenting cells currently under clinical development. We discuss the clinical therapeutic application of DC-10 as inducers of type 1 regulatory T cells for tailoring regulatory T-cell-based cell therapy, and the use of DC-10 as adoptive cell therapy for promoting and restoring tolerance in T-cell-mediated diseases.

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

  19. The Human Thioredoxin System: Modifications and Clinical Applications

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available The thioredoxin system, comprising thioredoxin (Trx, thioredoxin reductase (TrxR and NADPH, is one of the major cellular antioxidant systems, implicated in a large and growing number of biological functions. Trx acts as an oxidoreductase via a highly conserved dithiol/disulfide motif located in the active site (-Trp-Cys-Gly-Pro-Cys-Lys-. Different factors are involved in the regulation of Trx activity, including its expression level, localization, protein-protein interactions, post-translational modifications and some chemical inhibitors. Mammalian TrxRs are selenoproteins which have a –Cys-Val-Asn-Val-Gly-Cys- N-terminal active site, as well as a C-terminal selenium-containing active site. Besides two Cys-residues in the redox-regulatory domain of cytosolic Trx (Trx1, human Trx1 has three additional Cys-residues. Post-translational modifications of human Trx1 which are involved in the regulation of its activity can happen via modification of Cys-residues including thiol oxidation, glutathionylation and S-nitrosylation or via modification of other amino acid residues such as nitration of Tyr-49. Because of the numerous functions of the thioredoxin system, its inhibition (mainly happens via the targeting TrxR can result in major cellular consequences, which are potentially pro-oxidant in nature, leading to cell death via necrosis or apoptosis if overexpression of Trx and other antioxidative enzymes can not recuperate cell response. Considering this feature, several anticancer drugs have been used which can inhibit TrxR. Elevated levels of Trx and/or TrxR have been reported in many different human malignancies, positively correlated with aggressive tumor growth and poor prognosis. Moreover, anti-oxidative and anti-apoptotic effects of Trx are reasons to study its clinical application as a drug.

    2008-08-01

    Human oocytes that remained unfertilized in programmes of assisted reproduction have been analysed cytogenetically for more than 20 years to assess the incidence of aneuploidy in female gametes. However, the results obtained so far are not indisputable as a consequence of difficulties in evaluating oocyte chromosome preparations. Because of the lack of guidelines, we decided to summarize for the first time, the possible pitfalls in human oocyte chromosome analysis. Therefore, we screened the material from our previous studies and compiled representative, complicated cases with recommendations for their cytogenetic classification. We point out that maturity and size of the oocyte are important parameters and that fixation artefacts, as well as the particular structure of oocyte chromosomes, may predispose one to misinterpretations. Moreover, phenomena related to oocyte activation and fertilization are illustrated and explained. This compilation may help to avoid major problems in future studies and contribute to a more precise, and uniform assessment of human oocyte chromosomes.

    During the last 20 years, numerous clinical trials have examined the therapeutic usefulness of melatonin in different fields of medicine. The objective of this article is to review, in depth, the science regarding clinical trials performed to date. The efficacy of melatonin has been assessed as a treatment of ocular diseases, blood diseases, gastrointestinal tract diseases, cardiovascular diseases, diabetes, rheumatoid arthritis, fibromyalgia, chronic fatigue syndrome, infectious diseases, neurological diseases, sleep disturbances, aging and depression. Melatonin has been also used as a complementary treatment in anaesthesia, hemodialysis, in vitro fertilization and neonatal care. The conclusion of the current review is that the use of melatonin as an adjuvant therapy seems to be well funded for macular degeneration, glaucoma, protection of the gastric mucosa, irritable bowel syndrome, arterial hypertension, diabetes, side effects of chemotherapy and radiation in cancer patients or hemodialysis in patients with renal insufficiency and, especially, for sleep disorders of circadian etiology (jet lag, delayed sleep phase syndrome, sleep deterioration associated with aging, etc.) as well as in those related with neurological degenerative diseases (Alzheimer, etc.,) or Smith-Magenis syndrome. The utility of melatonin in anesthetic procedures has been also confirmed. More clinical studies are required to clarify whether, as the preliminary data suggest, melatonin is useful for treatment of fibromyalgia, chronic fatigue syndrome, infectious diseases, neoplasias or neonatal care. Preliminary data regarding the utility of melatonin in the treatment of ulcerative colitis, Crohn's disease, rheumatoid arthritis are either ambiguous or negative. Although in a few cases melatonin seems to aggravate some conditions, the vast majority of studies document the very low toxicity of melatonin over a wide range of doses.

    Cryptosporidium spp. infection is usually self-limited in immunocompetent hosts but can be severe and life threatening in children and in immunocompromised individuals including those with primary or acquired immunodeficiencies. One hundred and three faecal samples were collected from 35 hospitalised patients with different symptoms and tested for the presence of the parasite. Cryptosporidium oocysts were found in four of 35 patients (11.4%) using Ziehl-Neelsen staining of faecal smears and immunofluorescence assay, whereas 12 (34.3%) samples tested positive by nested polymerase chain reaction assay. Cryptosporidium DNA was detected in one bile sample but not in a liver tissue biopsy sample collected from a patient who suffered from sclerosing cholangitis. Sequence analysis of oocyst wall protein and beta-tubulin gene fragments revealed three different parasite species (Cryptosporidium hominis, Cryptosporidium meleagridis and Cryptosporidium parvum) in children with primary immunodeficiencies, whereas only C. parvum was found in immunocompetent individuals and in those with secondary immunodeficiencies. This study has revealed a high prevalence of Cryptosporidium infection in hospitalised patients in Poland and confirmed that molecular techniques enable a more sensitive detection of the parasite.

    Human C-peptide is determined by radioimmunoassay. On gel filtration of serum from a healthy subject and from a patient with islet cell carcinoma, C-peptide (MW 3025) appears ahead of insulin (MW 5808) and shows much higher molar concentrations than the hormone. Human proinsulin cross-reacts with our antiserum to synthetic human C-peptide. On direct determination of immunomeasurable C-peptide (IMCP) in fasting serum of 25 healthy subjects we find an average of 1.8 (+/- 0.4) ng/ml, corresponding to 60.4 X 10(-11) Mol/l. The molar concentration is about five-fold as compared to IMI (immuno-measurable insulin). IMCP and IMI patterns are not identical on stimulation of beta-cell secretion in healthy subjects by i.v. glucose or glucose-glibenclamide. This is probably due to differences in peripheral metabolism of both compounds. We conclude from our results that C-peptide determined in peripheral venous serum is a better indicator of beta-cell secretion than is insulin. Among 26 insulin-treated juvenile diabetics 15 show not measurable and 11 subnormal IMCP levels in fasting serum. No rise in IMCP is found 1-2 h following breakfast. Four juvenile patients receiving no insulin in a phase of total diabetes remission have normal or raised fasting IMCP concentrations. Only 2 out of 24 adult diabetics (16 treated with insulin and 8 with tablets) show non-measurable fasting IMCP concentrations, in another 4 patients values are below and in the remaining 18 cases above 1 ng/ml serum. Stimulation of beta-cell secretion through glucose-glibenclamide is more or less impaired in all adult diabetics compared to the healthy subjects.

  6. Detection of head-to-tail DNA sequences of human bocavirus in clinical samples.

    Directory of Open Access Journals (Sweden)

    Jessica Lüsebrink

    Full Text Available Parvoviruses are single stranded DNA viruses that replicate in a so called "rolling-hairpin" mechanism, a variant of the rolling circle replication known for bacteriophages like φX174. The replication intermediates of parvoviruses thus are concatemers of head-to-head or tail-to-tail structure. Surprisingly, in case of the novel human bocavirus, neither head-to-head nor tail-to-tail DNA sequences were detected in clinical isolates; in contrast head-to-tail DNA sequences were identified by PCR and sequencing. Thereby, the head-to-tail sequences were linked by a novel sequence of 54 bp of which 20 bp also occur as conserved structures of the palindromic ends of parvovirus MVC which in turn is a close relative to human bocavirus.

    The ligaments are human tissues that are used in the transplantation area. A ligament is an anatomical structure in band form, composed by resistant fibers that connect the tissues that unite the bones with the articulations. In an articulation, the ligaments allow and facilitate the movement inside the natural anatomical directions, while it restricts those movements that are anatomically abnormal, impeding lesions that could arise of this type of movements. The kneecap ligament is a very important tissue in the knee mobility and of walking in the human beings. This ligament can injure it because of automobile accidents, for sport lesions or illnesses, and in many cases the only form of recovering the knee movement is carried out a transplant with the purpose of replacing the damage ligament by allo gen kneecap ligament processed in specialized Tissue Banks where the tissue is sterilized with gamma radiation of {sup 60}Co at very low temperatures, obtaining high quality ligaments for clinical application in injured patients. The kneecap ligaments are processed in the Tissue Banks with a segment of kneecap bone, a segment of tibial bone, the contained ligament between both bones and in some cases a fraction of the quadriceps tendon. In this work is given a description of the selection method of the tissue that includes the donor's serologic control, the kneecap ligament processing in the Radio Sterilized Tissues Bank, its sterilization with gamma radiation of {sup 60}Co, also it is indicated like the clinical application of the allo gen ligament was realized in a hasty patient and whose previous crossed ligament was injured. Finally the results are presented from the tissue obtaining until the clinical application of it is, and in this case is observed a favorable initial evolution of the transplantation patient.

    Full Text Available Aim. The aim of this work is to describe a case of immediate implant placement after extraction of the upper right first premolar, with the use of CAD/CAM technology, which allows an early digital impression of the implant site with an intraoral scanner (MHT 3D Progress, Verona, Italy. Case Report. A 46-year-old female was referred with a disorder caused by continuous debonding of the prosthetic crown on the upper right first premolar. Clinically, there were no signs, and the evaluation of the periapical radiograph showed a fracture of the root, with a mesial well-defined lesion of the hard tissue of the upper right first premolar, as the radiolucent area affected the root surface of the tooth. It was decided, in accordance with the patient, that the tooth would be extracted and the implant (Primer, Edierre implant system, Genoa, Italy with diameter of 4.2 mm and length of 13 mm would be inserted. After the insertion of the implant, it was screwed to the scan abutment, and a scan was taken using an intraoral scanner (MHT 3D Progress, Verona, Italy. The scanned images were processed with CAD/CAM software (Exocad DentalCAD, Darmstadt, Germany and the temporary crown was digitally drawn (Dental Knowledge, Milan, Italy and then sent to the milling machine for production with a composite monoblock. After 4 months, when the implant was osteointegrated, it was not necessary to take another dental impression, and the definitive crown could be screwed in. Conclusion. The CAD/CAM technology is especially helpful in postextraction implant for aesthetic rehabilitation, as it is possible to immediately fix a provisional crown with an anatomic shape that allows an optimal healing process of the tissues. Moreover, the removal of healing abutments, and the use of impression copings, impression materials, and dental stone became unnecessary, enabling the reduction of the chair time, component cost, and patient’s discomfort. However, it is still necessary

    A Chikungunya virus (CHIKV) epidemic emerged in the Indian Ocean islands of the Comores, Reunion, Mayotte, Mauritius, the Seychelles and Madagascar in 2005 resulting in the infection of about 250.000 inhabitants and travellers in only one year. Beginning in March 2006 increasing numbers of CHIKV-like febrile illnesses were reported from various parts of India. We investigated 70 consecutive German travellers returning from the affected areas and presenting with arthralgia and/or fever suggestive of CHIKV infection. Eleven patients had serological evidence of CHIKV infection. Real-time RT-PCR for CHIKV was positive in two cases, one who returned from Mauritius and the other who came back from Rajasthan, Northern India. In both cases CHIKV was isolated and sequencing of the entire viral genome was performed. The nucleotide sequence data obtained for both CHIKV strains revealed a high level of identity to CHIKV isolates from the ongoing epidemic. In detail, we found only 18 nucleotide exchanges between the isolates from Mauritius and Rajasthan, resulting in only six amino acid changes (nsP1 T128K, T376M, nsP3 S472N, capsid P23S, V27I and E1-protein A226V). Although the excessive dimension of the 2005/2006 outbreak in the Indian Ocean islands was at least in part accounted to the naïve population affected, our results of the Rajasthan isolate support that the emergence of this CHIKV subtype may rather be a result of a better viral fitness. This has been previously accounted to a A226V change in the E1 protein of the new CHIKV variant when compared to other CHIKV data available. This mutation, supposedly resulting in high-titred viremia in humans and/or an enhanced adaptation to the vector population resulting in increased transmission rates, was also found in our CHIKV isolate from Mauritius. The spread of an African CHIKV to Asia further demonstrates how fast viruses can emerge and establish in places where competent vectors are prevalent.

    Using outpatient neurology clinic case logs completed by medical students on neurology clerkships, we examined the impact of outpatient clinical encounter volume per student on outcomes of knowledge assessed by the National Board of Medical Examiners (NBME) Clinical Neurology Subject Examination and clinical skills assessed by the Objective Structured Clinical Examination (OSCE). Data from 394 medical students from July 2008 to June 2012, representing 9,791 patient encounters, were analyzed retrospectively. Pearson correlations were calculated examining the relationship between numbers of cases logged per student and performance on the NBME examination. Similarly, correlations between cases logged and performance on the OSCE, as well as on components of the OSCE (history, physical examination, clinical formulation), were evaluated. There was a correlation between the total number of cases logged per student and NBME examination scores (r = 0.142; p = 0.005) and OSCE scores (r = 0.136; p = 0.007). Total number of cases correlated with the clinical formulation component of the OSCE (r = 0.172; p = 0.001) but not the performance on history or physical examination components. The volume of cases logged by individual students in the outpatient clinic correlates with performance on measures of knowledge and clinical skill. In measurement of clinical skill, seeing a greater volume of patients in the outpatient clinic is related to improved clinical formulation on the OSCE. These findings may affect methods employed in assessment of medical students, residents, and fellows.

    Full Text Available Clinical cases are primary and vital evidence for Traditional Chinese Medicine (TCM clinical research. A great deal of medical knowledge is hidden in the clinical cases of the highly experienced TCM practitioner. With a deep Chinese culture background and years of clinical experience, an experienced TCM specialist usually has his or her unique clinical pattern and diagnosis idea. Preserving huge clinical cases of experienced TCM practitioners as well as exploring the inherent knowledge is then an important but arduous task. The novel system ISMAC (Intelligent System for Management and Analysis of Clinical Cases in TCM is designed and implemented for customized management and intelligent analysis of TCM clinical data. Customized templates with standard and expert-standard symptoms, diseases, syndromes, and Chinese Medince Formula (CMF are constructed in ISMAC, according to the clinical diagnosis and treatment characteristic of each TCM specialist. With these templates, clinical cases are archived in order to maintain their original characteristics. Varying data analysis and mining methods, grouped as Basic Analysis, Association Rule, Feature Reduction, Cluster, Pattern Classification, and Pattern Prediction, are implemented in the system. With a flexible dataset retrieval mechanism, ISMAC is a powerful and convenient system for clinical case analysis and clinical knowledge discovery.

    The posturologic visit is a not widely known medical method for the evaluation and the therapy of low back pain. We describe the clinical and instrumental method followed in our posturological clinical unit organized jointly by hospital and university and the clinical cases evaluated in two years. An individual diagnostic evaluation and a personal therapy allowed an almost generalized complete remission of the symptoms and a very low number of reactivation of low back pain after a follow up of one years.

    As immunization programs for human papillomavirus (HPV) are implemented more widely around the world, interest is increasing in measuring their impact. One early measurable impact of HPV vaccine is on the prevalence of specific HPV types in a population. In low-resource settings, a potentially attractive strategy would be to monitor HPV prevalence using clinical cervical cancer screening test results to triage specimens for HPV typing. We assessed this approach in a nationally representative population of U.S. females aged 14-59 years. Using self-collected cervico-vaginal swab specimens from 4,150 women participating in the National Health and Nutrition Examination Survey during 2003-2006, we evaluated type-specific HPV prevalence detected by the Roche linear array (LA) research test on all specimens, compared with type-specific HPV prevalence detected by LA conducted only on specimens positive by the digene hybrid capture 2 (HC-2) clinical test. We calculated weighted prevalence estimates and their 95% confidence intervals (CIs), and examined relative type-specific HPV prevalence according to the two testing approaches. The population prevalence of oncogenic HPV vaccine types 16/18 was 6.2% (CI:5.4-7.1) by LA if all specimens were tested, and 2.4% (CI:1.9-3.0) if restricted to positive HC-2. Relative prevalence of individual HPV types was similar for both approaches. Compared with typing all specimens, a triage approach would require testing fewer specimens, but a greater reduction in HPV prevalence or a larger group of specimens would be needed to detect vaccine impact. Further investigation is warranted to inform type-specific HPV monitoring approaches around the world.

    Visceral leishmaniasis (VL, kala-azar) is a zoonotic infection caused by Leishmania species which are transmitted to humans by the bites of infected female phlebotomine sandflies. Leishmania infantum is the responsible species of VL in Aegean, Mediterranean, and Central Anatolia regions of Turkey mainly observed sporadically in pediatric age groups. The aim of this study was to evaluate the clinical and laboratory findings of adult patients with VL who were admitted to our hospital. A total of 10 patients (3 female, 7 male; age range: 18-67 years, mean age: 39.3 ± 16.51) followed in the infectious diseases clinic of the hospital between 2000 and 2013 were evaluated retrospectively. The diagnosis of VL was based on the presence of appropriate clinical and physical examination, as well as biochemical findings, positive serological test results (indirect fluorescent antibody test, and rK39 rapid antigen test) and/or detection of amastigote forms of parasite in the bone marrow aspiration samples. Of the cases three were diagnosed with both bone marrow and serology positivity, five with bone marrow positivity and one of each only with liver biopsy and positive serology result. Time interval from onset of the symptoms until the establishment of the specific clinical diagnosis was ranged from 2 to 12 weeks. The most frequent initial symptoms were fever, fatigue and abdominal distension. None of the patients had immunosupressive conditions such as HIV infection, corticosteroid use, immunosupressive treatment, or transplantation. All the patients were from Aegean region and six were living in rural areas. In all cases, hepatosplenomegaly, increased erythrocyte sedimentation rate, albumin/globulin ratio inversion, anemia, leukopenia and among nine cases trombocytopenia were detected. In one case acute renal failure has been developed before treatment and the patient was admitted to dialysis program. Bacterial superinfection occurred in two cases. Patients were treated with

    To investigate if there is vasculogenic mimicry (VM) in human primary gallbladder carcinoma and clinical significance thereof. Seventy-four specimens of primary gallbladder carcinoma obtained from operation underwent HE staining and double staining of CD(31) and PAS to observe the existence of VM. The correlation of pathological examination and clinical outcomes was analyzed. VM was seen in 10 of the 74 (13.5%) specimens. VM was not correlated with age, sex, location, diameter, differentiation degree, Nevin stage, and invasion depth of tumor, and existence of lymph node metastasis; but was associated with histological type (chi(2) = 10.241, P = 0.017), hepatic metastasis (chi(2) = 11.904, P = 0.01), and poor overall survival (chi(2) = 5.771, P = 0.016). Cox analysis showed that existence of VM, invasion depth, lymph node metastasis, hepatic metastasis, and operational method were independent risk factors of the prognosis of primary gallbladder carcinoma. VM exists in human primary gallbladder carcinoma. Those cases of human primary gallbladder carcinoma with VM have a poorer prognosis.

    Anaplasma species are obligate intracellular rickettsial pathogens that affect the health of humans and other animals. Clinical cases of anaplasmosis caused by Anaplasma phagocytophilum were evaluated, and the frequency of bovine Anaplasma species was determined in cattle. Blood samples and thin blood smears were collected from 10 cattle exhibiting clinical signs of tick-borne fever. In addition, blood samples were collected from 123 apparently healthy cattle from the same area. DNA was screened by reverse line blot assay for the presence of the hypervariable V1 region of the 16S rRNA gene of Anaplasma/Ehrlichia species. Intracytoplasmic inclusion bodies of A. phagocytophilum were observed in neutrophils of 6 sick animals. Parasitemia ranged from 0.2 to 1.6% in individual slides. Reverse line blot showed 45.1% (60/133) of the sampled cattle to be positive for one or more of five Anaplasma species. The frequency of single infections was 20.3% (27/133), while mixed infections were found in 24.8% (33/133) of samples with six different combinations of species and a maximum of four pathogens detected. A. phagocytophilum was the most prevalent (41/133, 30.8%) followed by Anaplasma marginale (25/133, 18.8%), Anaplasma centrale (24/133, 18%), Ehrlichia sp. strain Omatjenne (18/133, 13.5%) and Anaplasma bovis (1/133, 0.7%). This is the first report of A. bovis in a cow from Turkey. This is also the first report of clinical cases caused by A. phagocytophilum in cattle from the country. Therefore, A. phagocytophilum should be taken into account as differential diagnosis in cases of high fever and anorexia in pastured animals. Copyright © 2015 Elsevier B.V. All rights reserved.

    Clinical reasoning involves the use of both analytical and nonanalytical intuitive cognitive processes. Fostering student development of clinical reasoning skills and evaluating student performance in this cognitive arena can challenge educators. The use of Web-based unfolding cases is proposed as a strategy to address these challenges. Unfolding cases mimic real-life clinical situations by presenting only partial clinical information in sequential segments. Students receive immediate feedback after submitting a response to a given segment. The student's comparison of the desired and submitted responses provides information to enhance the development of clinical reasoning skills. Each student's set of case responses are saved for the instructor in an individual-student electronic file, providing a record of the student's knowledge and thinking processes for faculty evaluation. For the example case given, the approaches used to evaluate individual components of clinical reasoning are provided. Possible future uses of Web-based unfolding cases are described.

    Full Text Available Human trypanosoma infections like the ones seen in Africa and South America are unknown in India. The only exception in literature is of two documented cases of a self-limiting febrile illness, being attributed to Trypanosoma lewisi like parasites. We are reporting an unusual case of trypanosomiasis from the rural parts of Chandrapur district in Maharashtra. An adult male farmhand who used to practice veterinary medicine also, presented with history of febrile episodes on and off since five months and drowsiness before admission to this Institute. Though routine blood and other investigations were within normal limits, the peripheral smear showed a large number of trypanosomes which morphologically resembled the species Trypanosoma evansi , the aetiological agent of surra - a form of animal trypanosomiasis. A battery of assays covering the spectrum of parasitology, serology, and molecular biology confirmed the infecting parasite to be T. evansi . Failure to demonstrate the central nervous system (CNS involvement, as evidenced by the absence of parasite in cerebrospinal fluid (CSF advocated the use of suramin - the drug of choice in early stage African trypanosomiasis without any CNS involvement. Suramin achieved cure in our patient. The case is being reported because of its unique nature as the patient was not immunocompromised and showed infestation with a parasite which normally does not affect human beings.

    Yersinia pestis is a highly pathogenic gram-negative bacterium and the causative agent of human plague. In the last 1500 years and during three dreaded pandemics, millions of people became victims of Justinian's plague, the Black Death, or modern plague. Today, Y. pestis is endemic in natural foci of Asian, African and American countries. Due to its broad dissemination in mammal species and fleas, eradication of the pathogen will not be possible in the near future. In fact, plague is currently classified as a "re-emerging disease". Infection may occur after the bite of an infected flea, but also after oral ingestion or inhalation of the pathogen. The clinical presentations comprise the bubonic and pneumonic form, septicemia, rarely pharyngitis, and meningitis. Most human cases can successfully be treated with antibiotics. However, the high transmission rate and lethality of pneumonic plague require international and mandatory case notification and quarantine of patients. Rapid diagnosis, therapy and barrier nursing are not only crucial for the individual patient but also for the prevention of further spread of the pathogen or of epidemics. Therefore, WHO emergency schedules demand the isolation of cases, identification and surveillance of contacts as well as control of zoonotic reservoir animals and vectors. These sanctions and effective antibiotic treatment usually allow a rapid containment of outbreaks. However, multiple antibiotic resistant strains of Y. pestis have been isolated from patients in the past. So far, no outbreaks with such strains have been reported.

    Although obesity is well established in hamsters, studies using diets with high levels of simple carbohydrate associated with lipids are necessary to assess the impact of this type of food in the body. In this study a high sugar and butter diet (HSB) and high temperature were employed towards this end. Obesity was successfully induced at a temperature of 30.3°C to 30.9°C after 38 days feeding the animals an HSB diet. It was shown that although diet is important for the induction of obesity, temperature is also essential because at a temperature slightly below the one required, obesity was not induced, even when the animals were fed for a longer period (150 days).The obese clinical condition was accompanied by biochemical and hematological changes, as increased cholesterol and triglyceride levels and increased leukocyte numbers, similar to alterations observed in obese humans. Furthermore, it was demonstrated that increasing the intake of simple carbohydrates associated with lipids provided evidence of inflammation in obese animals.

    2014-01-01

    Full Text Available Introduction. Predictable endodontic treatment depends on the dentist’s knowledge about root canal morphology and its possible anatomic variations. The majority of mandibular canines have one root and root canal, but 15% may have two canals and a smaller number may have two distinct roots. The following clinical reports describe endodontic treatment of mandibular canines with two roots and two root canals. Outline of Cases. Four clinical case reports are presented to exemplify anatomical variation in the human mandibular canine. Detailed analysis of the preoperative radiographs and careful examination of the pulp chamber floor detected the presence of two root canal orifices in all canines. Working length was determined with an electronic apex locator and biomechanical preparation was carried out by using engine driven BioRaCe Ni-Ti rotary instruments in a crown-down manner, followed by copious irrigation with 1% sodium hypochlorite. Definitive obturation was performed using cold lateral condensation with gutta-percha cones and Top Seal paste. The treatment outcome was evaluated using postoperative radiographs. Conclusion. Endodontists should be aware of anatomical variations of the treated teeth, and should never presume that canal systems are simple.

    2003-12-01

    Full Text Available It is suggested that ecotourism development on the island of Bonaire can be productively understood as a perturbation of a complex human ecosystem. Inputs associated with ecotourism have fueled transformations of the island ecology and sociocultural system. The results of this study indicate that Bonaire's social and economic hierarchy is approaching a new, stable systems state following a 50-yr transition begun by government and industry that stabilized with the appearance of ecotourism development and population growth. Ecotourism can be understood to have "filled in" the middle of the production hierarchy of Bonaire. Interpreted from this perspective, population growth has completed the transformation by expanding into production niches at smaller scales in the production hierarchy. Both a consequence and a cause, ecotourism has transformed the island's social structure and demography. The theory and methods applied in this case study of interdisciplinary research in the field of human ecosystems are also presented.

MethodsA retrospective analysis was performed on the clinical data of 70 inpatients diagnosed with PBC from January 2008 to March 2013. The initial symptoms, liver function, and antimitochondrial antibody (AMA subtypes (M2, M4, and M9 of patients, as well as the pathological results of 3 cases, were recorded. The increases in alanine aminotransferase (ALT, aspartate aminotransferase (AST, alanine phosphatase (ALP, and gamma-glutamyl transpeptidase (GGT were analyzed by Wilcoxon rank sum test. ResultsOf all patients, 84.3% were females; the mean age was 59.2±8.7 years. The main clinical manifestations included weakness (25.7%, itching (24.3%, discomfort in the upper right abdominal quadrant (18.6%, and abdominal distension (18.6%. Abnormal liver function was mainly characterized by significant increases in GGT (324.5±250.4 U/L and ALP(381.1±259.0 U/L. The number of patients with more than 5-fold increase in GGT was significantly higher than the numbers of patients with more than 5-fold increases in ALT, AST, and ALP (u=-5.861, P=0000; u=-4.036, P=0.000; u=-4.445, P=0.000. The numbers of patients with more than 2-fold increases in AST and ALP were significantly higher than the number of patients with more than 2-fold increase in ALT (u=-4.405, P=0.000; u=-3.625, P=0.000. Among all patients, 87.1% were positive for antimitochondrial M2 antibody (AM2A, 31.4% were positive for AM4A, and 114% were positive for AM9A. ConclusionPBC, more common in females, is the chronic liver damage characterized by significant increases in GGT and ALP. Detection of AMA subtypes (M2, M4and M9 is valuable for confirming the diagnosis of PBC.

    To investigate the distribution and change of the causes of fever of unknown origin(FUO). The clinical data of 500 inpatients with FUO in our center between December 2003 and June 2014 were retrospectively analyzed. The diagnostic methods,etiologies,and their possible relationship with age,sex,fever duration,and period. Of these 500 FUO patients,452(90.4%)were confirmed to be with fever caused by conditions including infectious diseases [(n=231,46.2%;e.g.tuberculosis(32.9%,76/231)],connective tissue diseases(CTD)(n=99,19.8%),neoplasms(n=58,11.6%),miscellaneous causes(n=64,12.8%). The causes were not identified in 48 cases(9.6%).The proportion of CTD in female patients was significantly higher than that in male patients(26.3% vs. 14.5%,P=0.025),whereas the proportion of neoplasms in male patients was significantly higher than that in female patients(14.5% vs. 8.0%,P=0.001). Infectious diseases was the most common cause in all age groups,CTD ranked the second in the 21-39-year group and 40-59-year group,and neoplasm was the second most coomon cause in the over 60 year group. Thus,the distribution of FUO etiologies significantly differed in different age groups(χ(2)=43.10,P=0.000). The duration of fever in patients with neoplasms [60(28,90)d] was longer than that in patients with infectious diseases [28(21,42)d,Z=-4.168,P=0.000] or CTD [30(21,60)d,Z=-2.406,P=0.016)]. Compared with the level in 2003-2008,the proportion of CTD significantly increased in 2009-2014(13.7% vs. 23.8%,χ(2)=8.598,P=0.003),along with the dicrease of the proportions of infectious diseases,neoplasms and miscellaneous diseases were decreased(all P>0.05). Infectious diseases(in particular,tuberculosis)remains the major cause of FUO. CTD and neoplasms also play important roles in the development of FUO. The distributions of the FUO etiologies have certain differences in terms of age,sex,duration of fever,and period.

    Efficient communication of a clinical study protocol and case report forms during all stages of a human clinical study is important for many stakeholders. An electronic and structured study representation format that can be used throughout the whole study life-span can improve such communication and potentially lower total study costs. The most relevant standard for representing clinical study data, applicable to unregulated as well as regulated studies, is the Operational Data Model (ODM) in development since 1999 by the Clinical Data Interchange Standards Consortium (CDISC). ODM's initial objective was exchange of case report forms data but it is increasingly utilized in other contexts. An ODM extension called Study Design Model, introduced in 2011, provides additional protocol representation elements. Using a case study approach, we evaluated ODM's ability to capture all necessary protocol elements during a complete clinical study lifecycle in the Intramural Research Program of the National Institutes of Health. ODM offers the advantage of a single format for institutions that deal with hundreds or thousands of concurrent clinical studies and maintain a data warehouse for these studies. For each study stage, we present a list of gaps in the ODM standard and identify necessary vendor or institutional extensions that can compensate for such gaps. The current version of ODM (1.3.2) has only partial support for study protocol and study registration data mainly because it is outside the original development goal. ODM provides comprehensive support for representation of case report forms (in both the design stage and with patient level data). Inclusion of requirements of observational, non-regulated or investigator-initiated studies (outside Food and Drug Administration (FDA) regulation) can further improve future revisions of the standard.

    Rhizoctonia solani is a most widely recognized strong saprophyte with a great diversity of host plants. It is a first ever case of extensive human mycosis caused by Rhizoctonia solani in a 65-year-old diabetic and hypertensive farmer, with a history of head injury caused by fall of mud wall. Necrotic material collected revealed septate fungal hyphae with bacterial co-infection. Fungal culture on SDA at 25°C showed cotton wooly growth progressing to greyish-white to shiny metallic black colonies and identified on basis of septate mycelial growth without conidia, right angle branching, presence of compact hyphal forms and anastomosis between branching hyphae on LPCB mount.

    This study considers the complex dynamics of work motivation. Forty-eight employees completed a work-motivation diary several times per day over a period of four weeks. The obtained time series were analysed using different methodologies derived from chaos theory (i.e. recurrence plots, Lyapunov exponents, correlation dimension and surrogate data). Results showed chaotic dynamics in 75% of cases. The findings confirm the universality of chaotic behavior within human behavior, challenge some of the underlying assumptions on which work motivation theories are based, and suggest that chaos theory may offer useful and relevant information on how this process is managed within organizations.

    Non-Hodgkin's lymphoma (NHL) is the third common malignant lesion of the oral region. Plasmablastic lymphomas are rare, aggressive neoplasms occurring mostly in human immunodeficiency virus (HIV) infected individual which accounts for approximately 2.6% of all NHL. It usually presents as a diffuse growth and with diffuse pattern of histological presentation. It is very difficult to differentiate this lymphoma from other NHL. Immunohistochemical evaluation of various markers is an important criteria of the diagnostic protocol. Here, we describe a case of plasmablastic lymphoma in a 50-year-old female HIV-infected patient. The diagnosis was based on histopathological examination and immunophenotyping. PMID:27795651

    Toxocariasis is a helminthozoonosis due to the infection of humans with larvae belonging to the Toxocara genus. Humans become infected as a result of accidental consumption of infected eggs containing third stage larvae (L3) nematodes from Toxocara canis or Toxocara cati species. Toxocariasis was recognized for the first time in the early 1950s, and the first cases of toxocariasis in Poland were described a few years later. Toxocariasis is clinically classified into several types: classic and incomplete visceral larva migrans (VLM) syndrome, ocular larva migrans (OLM) syndrome, neurological toxocariasis (NLM), covert toxocariasis and asymptomatic toxocariasis. In 1994-2005, 18,367 sera of people suspected of being infected with Toxocara were analysed, 1.8-76% had anti- Toxocara antibodies. In the period 1978-2009, 1,022 clinical cases of toxocariasis were recognized in Poland. In the opinion of the authors, in order to reduce the frequency of toxocariasis in human populations, some prophylaxis should undertaken, e.g. public education of zoonotic diseases, systematic control of animal, deworming of pets, cleaning pets' faeces by the owners.

  18. A Safety-Case Regime for Commercial Human Spaceflight

    Sgobba, T.; Trujillo, M.

    2012-01-01

    Currently the commercial human spaceflight community seems to be embracing the obsolete design principles of "fly-fix-fly", and betting on public acceptance of risks comparable to those of the early times of aviation industry. The nascent space tourism industry maintains that early safety regulations (apart public safety) would kill industry and that such regulations could be developed only later when substantial operational experience is gained. Truly, most of current commercial aviation safety regulations are based on prescriptive requirements (i.e. explicitly required design solution for an implicit goal), which have been incrementally developed over more than a half century of mass transportation by air, and cannot be in general directly applied to innovative systems. However modern complex safety-critical systems cannot risk catastrophic failures while their operational experience is being accumulated, for such reason they are developed through the so called safety-case regime. ESA is currently drafting a safety standard for its future human rated transportation systems that is based on such regime. Such standard can be easily tailored with few modifications and applied to the development of a sub-orbital commercial space vehicle. In any case, because the safety-case regime makes extensive use of generically formulated requirements, the support of skilled safety engineers fully integrated into the design team is required since the very beginning. Furthermore the safety certification team needs also to be experienced in the review of safety-case based designs. Finally a quantitative safety target needs to be included and verified as the ultimate "prove of goodness" of system design.

    Sarcomatoid mesothelioma is the least common, but most aggressive of the three major histological types of mesotheliomas. This study comprises 326 cases of sarcomatoid mesotheliomas among 2000 consecutive malignant mesothelioma cases received in consultation (16%). Patients included 312 men (96%) and 14 women (4%), with a median age of 70 years (range 41-94 years). Most tumors were pleural (319; 98%), and 7 were peritoneal (2%). Some desmoplastic features were identified in 110 cases (34%), and 70 (21%) were classified as desmoplastic. Rare subtypes included two cases with a lymphohistiocytoid pattern (mesotheliomas (2%). Labeling for cytokeratins (CKs) was observed in 261/280 cases (93%), and for calretinin and vimentin in 31 and 91%, respectively. Pleural plaques were present in 79% of cases for which information was available, and asbestosis was diagnosed in 34/127 cases (27%). Median survival was 3.5 months. Fiber analysis was performed in 61 cases. The median asbestos body count was 1640/g wet lung tissue (by light microscopy). Amosite fibers were the most commonly identified fibers using energy-dispersive X-ray analysis and were significantly higher in the sarcomatoid cases, as were uncoated fibers using scanning electron microscopy. This study represents the largest series of sarcomatoid and desmoplastic malignant mesotheliomas to date and confirms the diagnostic usefulness of CK immunohistochemistry. The relationship with asbestos exposure--particularly amosite--and an association with pleural plaques and less often asbestosis is confirmed.

    Recent advances in stem cell technologies have rekindled an interest in the use of cell replacement strategies for patients with Parkinson disease. This study reports the very long-term clinical outcomes of fetal cell transplantation in 2 patients with Parkinson disease. Such long-term follow-up data can usefully inform on the potential efficacy of this approach, as well as the design of trials for its further evaluation. Two patients received intrastriatal grafts of human fetal ventral mesencephalic tissue, rich in dopaminergic neuroblasts, as restorative treatment for their Parkinson disease. To evaluate the very long-term efficacy of the grafts, clinical assessments were performed 18 and 15 years posttransplantation. Motor improvements gained gradually over the first postoperative years were sustained up to 18 years posttransplantation, while both patients have discontinued, and remained free of any, pharmacological dopaminergic therapy. The results from these 2 cases indicate that dopaminergic cell transplantation can offer very long-term symptomatic relief in patients with Parkinson disease and provide proof-of-concept support for future clinical trials using fetal or stem cell therapies.

    2008-11-06

    Effective standardization of clinical processes, which is a growing priority for healthcare provider organizations and networks, requires effective teamwork among clinicians and staff from multidisciplinary backgrounds--often from geographically dispersed facilities--to reach consensus on care practices. Yet, most healthcare provider organizations have no precedence or tools for managing large-scale, sustained, collaborative activities. This presentation explores the human and social implications of technology. It specifically addresses healthcare collaboration and describes how innovative collaboration management technologies can be used in the healthcare industry to accelerate care standardization, order set standardization and other initiatives necessary for successful computerized provider order entry and electronic health record deployments. These topics are explored through presentation of a survey of healthcare executives and a case study of an advanced collaboration application that was adapted and deployed in a partnership between a large healthcare provider organization and a commercial developer of document management and collaboration management technologies.

    This paper is a clinical study of 57 cases of infection with Trichophyton tonsurans (T. tonsurans) examined in our clinic between January 2004 and July 2006. The patients were 31 high school students, 19 junior high school students, 2 primary school students, 1 kindergartener, and 4 sports instructors. The male:female ratio was 51:6. Most patients were male Judo practitioners. Patients were clinically categorized as follows: 13 cases of tinea capitis {10 containing black dot ringworms (BDR), 2 scaled, and 1 with inflammation}, 41 cases of tinea corporis, 1 case of tinea manum, and 7 carriers. Five patients displayed both tinea capitis and tinea corporis. Among tinea corporis patients, 21 displayed annular erythemas, whereas 19 displayed small circular eythemas characterized by a lightly inflamed non-typical rush. In 3 tinea corporis cases, we sampled T. tonsurans from hair grown inside the skin rash. Eleven of the tinea corporis patients displayed multiple lesions. Compared to patients with singular lesions, these 11 cases had a larger degree of comorbidity with BDR or HB positivity. A 6-8 week treatment with griseofulvin was efficient in 90% of the tinea capitis cases. Tinea corporis patients were healed following a 4-9 week treatment with topical antifungals and griseofulvin. When examining T. tonsurans infections, patients with BDR or lightly inflamed tinea corporis as well as asymptomatic carriers can be easily overlooked or misdiagnosed. Therefore, we suggest that mycological examination, including careful observation of the rash and KOH mount, is essential in these cases.

    Full Text Available This study explores the perception of satisfaction of caregivers who attended a feeding clinic at a large pediatric hospital in the midwest. The clinic is designed for a multidisciplinary team to meet with the child and the caregiver. Thirty-five participants were involved in the study. Results indicated that most participants were satisfied with the clinic experience. However, there were areas of care not covered by the members of the feeding team, which indicates a need. It is suggested that this need could be filled by occupational therapists.

    The objective of this study was to determine whether the occurrence of a previous case of pathogen-specific clinical mastitis (CM) protects Holstein dairy cows against a recurrent case. Pathogens studied were Escherichia coli, Staphylococcus aureus, Staphylococcus spp., Streptococcus spp., Klebsiella spp., and Trueperella pyogenes. A total of 40 864 lactations (17,265 primiparous and 23,599 multiparous) from 19 835 cows from 5 large, high milk producing New York State dairy herds were analysed. We estimated the effects of parity, calving diseases, milk yield, current season and number of CM cases in the previous lactation on the risk of a first CM case using generalised linear mixed models with a log link and Poisson error distribution. The aforementioned risk factors and the occurrence of previous cases of pathogen-specific CM within the current lactation were evaluated as risks for second and third cases of pathogen-specific CM. Cows with more CM cases in the previous lactation were at greater risk of pathogen-specific CM in the current lactation. Multiparous cows were at greater risk of a second CM case if they had suffered from a first CM case that was caused by the same pathogen as the second case. In contrast, a second CM case generally put cows at greater risk of a third case, irrespective of whether the third case was caused by the same or a different pathogen. Our results showed that a previous case of pathogen specific CM does not generally protect against a recurrent case.

    This paper contributes to recent studies exploring the longue durée of human impacts on island landscapes, the impacts of climate and other environmental changes on human communities, and the interaction of human societies and their environments at different spatial and temporal scales. In particular, the paper addresses Iceland during the medieval period (with a secondary, comparative focus on Norse Greenland) and discusses episodes where environmental and climatic changes have appeared to cross key thresholds for agricultural productivity. The paper draws upon international, interdisciplinary research in the North Atlantic region led by the North Atlantic Biocultural Organization (NABO) and the Nordic Network for Interdisciplinary Environmental Studies (NIES) in the Circumpolar Networks program of the Integrated History and Future of People on Earth (IHOPE). By interlinking analyses of historically grounded literature with archaeological studies and environmental science, valuable new perspectives can emerge on how these past societies may have understood and coped with such impacts. As climate and other environmental changes do not operate in isolation, vulnerabilities created by socioeconomic factors also beg consideration. The paper illustrates the benefits of an integrated environmental-studies approach that draws on data, methodologies and analytical tools of environmental humanities, social sciences, and geosciences to better understand long-term human ecodynamics and changing human-landscape-environment interactions through time. One key goal is to apply previously unused data and concerted expertise to illuminate human responses to past changes; a secondary aim is to consider how lessons derived from these cases may be applicable to environmental threats and socioecological risks in the future, especially as understood in light of the New Human Condition, the concept transposed from Hannah Arendt's influential framing of the human condition that is

    Valve disease is common and is increasing in prevalence as the population ages. The delivery of appropriate management is not always straightforward, and better ways of organizing care are required. Here, the argument is made for a specialist multidisciplinary valve clinic, while a description is provided of the authors' model clinic, which incorporates a specialist cardiologist in addition to sonographers and a nurse who carry out the surveillance services. The clinic is based at a cardiothoracic center and one district hospital, but could be generalized. Previous audits have shown that this model can reduce the number of patients seen by a cardiologist, thus improving the safety and quality of treatment compared to conventional clinics.

    This paper, the last in a series of three on 'feline leprosy', provides a detailed description of disease referable to the previously unnamed species, Candidatus 'Mycobacterium lepraefelis', a close relative of the human pathogens Mycobacterium leprae and Mycobacterium lepromatosis. Cases were sourced retrospectively and prospectively for this observational study, describing clinical, geographical and molecular microbiological data for cats definitively diagnosed with Candidatus 'M lepraefelis' infection. A total of 145 cases of feline leprosy were scrutinised; 114 'new' cases were sourced from the Victorian Infectious Diseases Reference Laboratory (VIDRL) records, veterinary pathology laboratories or veterinarians, and 31 cases were derived from six published studies. Thirty-eight cats were definitively diagnosed with Candidatus 'M lepraefelis' infection. Typically, cats tended to be middle-aged or older when first infected, with a male predilection. Affected cats typically had widespread cutaneous lesions, in some cases after initially localised disease. Advanced cases were often systemically unwell. All cats had outdoor access. The histological picture was lepromatous in the majority of patients, although two cases had tuberculoid disease. In one case that underwent necropsy, lesions were evident in the liver, spleen and lungs. Treatment was varied, although most cats received a combination of oral clarithromycin and rifampicin. Prognosis for recovery was variable, but typically poor. Candidatus 'M lepraefelis' typically causes high bacterial index (lepromatous) feline leprosy that in some cases progresses to systemic mycobacteriosis. The disease has a variable clinical course and prognosis. Many cases either died or were euthanased due to the infection. Multilocus sequence analysis reveals a heterogeneous picture and further analysis of draft genome sequencing may give clues to the taxonomy and epidemiology of this organism.

  17. Human REM sleep: influence on feeding behaviour, with clinical implications.

    Science.gov (United States)

    Horne, James A

    2015-08-01

    Rapid eye movement (REM) sleep shares many underlying mechanisms with wakefulness, to a much greater extent than does non-REM, especially those relating to feeding behaviours, appetite, curiosity, exploratory (locomotor) activities, as well as aspects of emotions, particularly 'fear extinction'. REM is most evident in infancy, thereafter declining in what seems to be a dispensable manner that largely reciprocates increasing wakefulness. However, human adults retain more REM than do other mammals, where for us it is most abundant during our usual final REM period (fREMP) of the night, nearing wakefulness. The case is made that our REM is unusual, and that (i) fREMP retains this 'dispensability', acting as a proxy for wakefulness, able to be forfeited (without REM rebound) and substituted by physical activity (locomotion) when pressures of wakefulness increase; (ii) REM's atonia (inhibited motor output) may be a proxy for this locomotion; (iii) our nocturnal sleep typically develops into a physiological fast, especially during fREMP, which is also an appetite suppressant; (iv) REM may have 'anti-obesity' properties, and that the loss of fREMP may well enhance appetite and contribute to weight gain ('overeating') in habitually short sleepers; (v) as we also select foods for their hedonic (emotional) values, REM may be integral to developing food preferences and dislikes; and (vii) REM seems to have wider influences in regulating energy balance in terms of exercise 'substitution' and energy (body heat) retention. Avenues for further research are proposed, linking REM with feeding behaviours, including eating disorders, and effects of REM-suppressant medications.

  18. Clinical Case Reporting in the Peer-Reviewed Physical Therapy Literature: Time to Move Toward Functioning.

    Science.gov (United States)

    Davenport, Todd E

    2015-12-01

    Physical therapists increasingly are contributing clinical case reports to the health literature, which form the basis for higher quality evidence that has been incorporated into clinical practice guidelines. Yet, few resources exist to assist physical therapists with the basic mechanics and quality standards of producing a clinical case report. This situation is further complicated by the absence of uniform standards for quality in case reporting. The importance of including a concise yet comprehensive description of patient functioning in all physical therapy case reports suggest the potential appropriateness of basing quality guidelines on the World Health Organization's International Classification of Functioning Disability and Health (ICF) model. The purpose of this paper is to assist physical therapists in creating high-quality clinical case reports for the peer-reviewed literature using the ICF model as a guiding framework. Along these lines, current recommendations related to the basic mechanics of writing a successful clinical case report are reviewed, as well and a proposal for uniform clinical case reporting requirements is introduced with the aim to improve the quality and feasibility of clinical case reporting in physical therapy that are informed by the ICF model.

    Full Text Available Human immunodeficiency virus (HIV and M. tuberculosis are two intracellular pathogens that interact with each other at both clinical and cellular levels. A known HIV positive case, presentingwith vague pulmonary symptoms followed by bilateral cervical lymphadenopathy, is reported here. The condition was treated as asthma, based on lung symptoms. Cytology revealed acute purulent lymphadenitis. Only Z. N. staining and culture of sputum and lymphnode aspirate could diagnose tuberculosis. Patient responded well to the standard anti tuberculosis treatment.

    Background Clostridium difficile is a leading infectious cause of health care associated diarrhoea. Several industrialised countries have reported increased C. difficile infections and outbreaks, which have been attributed to the emergent PCR ribotype 027 strain. Methods and Findings We conducted a case-case study to compare severity of C. difficile disease for patients with 027 versus non-027 ribotypes. We retrospectively collected clinical information about 123/136 patients with C. difficile infections admitted to hospitals in the East of England region in 2006 and from whom stool isolates were cultured and ribotyped as part of an earlier national survey. We defined severe C. difficile disease as having one or more of shock, paralytic ileus, pseudo membranous colitis or toxic megacolon. Patient median age was 83 years old (range 3 to 98, interquartile range 75 to 89), 86% were prescribed antibiotics in the eight weeks before illness onset, 41% had ribotype 027 and 30-day all cause mortality during hospital admission was 21%. Severe disease occurred in 24% (95%CI 13% to 37%) and 17% (95%CI 9% to 27%) of patients with PCR ribotype 027 and non-027 ribotypes respectively. In a multivariable model, ribotype 027 was not associated with severe disease after adjusting for sex, discharge from hospital prior to 60 days of current admission, gastroenteritis on admission, number of initiator antibiotics for C. difficile disease, and hospital where the patient was admitted. Conclusions Our study found no evidence to support previous assertions that ribotype 027 is more virulent than other PCR ribotypes. This finding raises questions about the contribution of this strain to the recent increase in C. difficile disease throughout North America and Europe. PMID:18350149

    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

    We describe an innovative program at the University of California, Davis for students to engage in clinical needs finding. Using a team-based approach, students participated in clinical rotations to observe firsthand the needs of clinicians at the university affiliated medical center. The teams were asked to develop documentary-style videos to capture key experiences that would allow future viewers to use the videos as “virtual” clinical rotations. This was conceived as a strategy to allow students in prohibitively large classes, or students in programs at institutions without associated medical or veterinary school programs, to experience clinical rotations and perform needs assessments. The students' perspectives on the experience as well as instructor analysis of best practices for this type of activity are presented and discussed. We found that the internship experience was valuable to the students participating, by not only introducing the practice of needs finding but for increasing the students' confidence in the practice of engineering design and their ability to work independently. The videos produced were of such high quality that instructors from other institutions have requested copies for instructional use. Virtual clinical rotations through video experiences may provide a reasonable substitute for students who do not have the ability to participate in rotations in person. PMID:23483373

  9. Supreme Court to hear Florida clinic access case.

    1994-04-15

    On April 27, 1994, the US Supreme Court will review a Florida Supreme Court decision ensuring access to women's health clinics that offer abortion services. In October 1993, the Florida High Court determined that an order issued by Brevard/Seminole County Circuit Judge Robert McGregor that requires anti-abortion protestors to remain 36 feet from the clinic grounds, prohibits approaching any clinic patient within 300 feet of the facility, bars excessive noise during clinic hours, and creates a 300 foot safety zone around the homes of clinic staff was reasonable. Anti-abortion activists had challenged Judge McGregor's injunction, maintaining that it violated their First Amendment rights and was overboard. Days before the Florida High Court ruling, however, the US Court of Appeals for the Eleventh Circuit had rejected Judge McGregor's injunction as unconstitutional. Although the appeal to the US Supreme Court, Madsen vs Women's Health Center, was filed by anti-abortion activists, pro-choice groups are supporting the review as a means of resolving the confusion created by conflicting state and federal rulings.

    This report describes 4 patients presenting with multiple teeth affected by invasive cervical resorption (ICR). The cases came to our attention between 2006 and 2008; previously, no cases of multiple ICR (mICR) had been reported in Switzerland. Characteristics common to all 4 cases included progression of disease over time, similar clinical and radiographic appearance of lesions, and obscure etiology. The histologically assessed teeth showed a similar pattern of tooth destruction, with resorptive lesions being confined to the cervical region. Howship's lacunae and multinucleated, tartrate-resistant acid phosphatase-positive odontoclasts were detected. None of the teeth presented with internal resorption. The positive pulp sensitivity corresponded to the histologic findings, indicating that the pulp tissue resisted degradation even in advanced stages of resorptive lesions. Although mICR is rare in humans, a similar disease known as feline odontoclastic resorptive lesions (FORL) is common in domestic, captive, and wild cats. The etiology of FORL, like that of mICR, remains largely unknown. Because FORL has been associated with feline viruses, we asked our mICR patients whether they had had contact with cats, and interestingly, all patients reported having had direct (2 cases) or indirect (2 cases) contact. In addition, blood samples were taken from all patients for neutralization testing of feline herpes virus type 1 (FeHV-1). Indeed, the sera obtained were able to neutralize (2 cases) or partly inhibit (2 cases) replication of FeHV-1, indicating transmission of feline viruses to humans. Future studies on mICR (and FORL) should evaluate the possible role of a (feline) virus as an etiologic (co-)factor in this disease.

    Streptococcus suis, a bacterium that affects pigs, is a neglected pathogen that causes systemic disease in humans. We conducted a systematic review and meta-analysis to summarize global estimates of the epidemiology, clinical characteristics, and outcomes of this zoonosis. We searched main literature databases for all studies through December 2012 using the search term "streptococcus suis." The prevalence of S. suis infection is highest in Asia; the primary risk factors are occupational exposure and eating of contaminated food. The pooled proportions of case-patients with pig-related occupations and history of eating high-risk food were 38.1% and 37.3%, respectively. The main clinical syndrome was meningitis (pooled rate 68.0%), followed by sepsis, arthritis, endocarditis, and endophthalmitis. The pooled case-fatality rate was 12.8%. Sequelae included hearing loss (39.1%) and vestibular dysfunction (22.7%). Our analysis identified gaps in the literature, particularly in assessing risk factors and sequelae of this infection.

    Human African trypanosomiasis (HAT), also referred to as "sleeping sickness", is caused by the parasite Trypanosoma brucei. Diagnosing imported HAT outside endemic areas is difficult and diagnosis is often delayed. We report a case of imported human African trypanosomiasis caused by Trypanosoma brucei gambiense with an unusually long incubation period of at least 7 years. A 33 year old male African patient, a former resident of Cameroon, presented with a 4-month history of progressive personality changes. A few weeks before presentation the patient had first been admitted to a psychiatric ward and received antidepressant treatment, until a lumbar puncture showed pleocytosis and then antibiotic treatment for suspected neuroborreliosis was initiated. The patient continued to deteriorate during antibiotic treatment and became increasingly lethargic. Under antiparasitic and anti-inflammatory treatment, the condition of the patient gradually improved over the following months and he recovered completely after 24 months of follow-up. This well-documented case illustrates typical difficulties in establishing the correct diagnosis outside endemic areas and provides an overview of typical clinical, neuropathological and neuroimaging findings in T. b. gambiense trypanosomiasis, guiding the clinician in establishing the correct diagnosis in this rare disease.

    Bioethics in research is an essential part of the structured review process of an article and it is based on three fundamental principles: respect for persons, beneficence and justice. In addition to not providing valid knowledge, a research with inadequate design, execution and statistical analysis is not ethical either, since these methodological deficiencies will produce information that will not be useful and, therefore, the risks that the participants were exposed to will have been in vain. Beyond scientific validity, there are other aspects that outline if an investigation is ethical, such as the clinical and social value of a study, a fair selection of participants, favorable risk-benefit balance, an independent review, the informed consent and respect for participants and potential participants. Throughout the article here presented, the documents that profile the behavior of investigators to protect the participants, such as the Declaration of Helsinki, the national regulations that rule us and the differences between research without risk, with minimal risk and with greater than minimal risk are discussed. That like in daily life, behavior in research involving human participants must be self-regulated, ie, people with knowledge of the existence of the law discover that the man is outside the realm of nature where work is done under the necessity of natural causality, and falls within the scope of the will; only if the man is free to decide their actions may be a law regulating their action.

  20. The politics of nursing: a case study--clinical grading.

    Science.gov (United States)

    Gavin, J N

    1995-08-01

    This paper is a study of the clinical grading policy for nurses in the United Kingdom and the extent to which the participating groups in the policy development process realized their objectives. The study is based on the literature available at the time of the research and the results of structured interviews with a range of individuals involved in the policy process. The results expose the cleavages between the different representative groups on the staff side. They also shed light on the differing power bases of the groups involved. In particular, they expose the weakness of nursing as a professional pressure group and the strength of the state and its agents in determining the outcomes of policy in the public arena. It is suggested that this weakness vis-à-vis the state is responsible for the failure of nurses to achieve a reward system which recognizes the value of clinical nursing expertise, and that the 'clinical grading' system, in practice, is having the opposite effect. The policy is explored from its origins, its acceptance on to the political agenda, its negotiation and agreement, its contentious implementation, the final outcomes, and its failure to establish a valid 'clinical' pay structure.

  1. Human imprinting anomalies in fetal and childhood growth disorders: clinical implications and molecular mechanisms.

    Genomic imprinting is among the most important epigenetic mechanisms whereby expression of a subset of genes is restricted to a single parental allele. Loss of imprinting (LOI) through hypo or hyper methylation is involved in various human syndromes. These LOI occur early during development and usually impair growth. Some imprinting syndromes are the consequences of genetic anomalies, such as uniparental disomies (UPD) or copy number variations (deletion or duplications) involving the imprinted domains; others are due to LOI at the imprinting control regions (ICR) regulating each domain. Imprinting disorders are phenotypically heterogeneous, although some share various common clinical features such that diagnosis may be difficult. Multilocus imprinting defects associated with several syndromes have been increasingly reported in recent years, although there are no obvious clinical differences between monolocus and multilocus LOI patients. Subsequently, some rare mutations of transacting factors have been identified in patients with multilocus imprinting defects but they do not explain the majority of the cases; this therefore implies that other factors are involved. By contrast, no mutation of a transacting factor has yet been identified in monolocus LOI. The effect of the environment on the regulation of imprinting is clearly illustrated by studies of assisted reproductive technology (ART). The regulation of imprinting is complex and involves a huge range of genetic and environmental factors; the identification of these factors will undoubtedly help to elucidate the regulation of imprinting and contribute to the understanding of imprinting disorders. This would be beneficial for diagnostics, clinical follow up and the development of treatment guidelines.

    Human neurocysticercosis (NC) is endemic in most countries of Latin America, Asia and Africa and is re-emerging in some industrialized nations. Both within and among endemic countries, NC is very variable in its clinical and radiological features, as well as in the intensity of the immuno-inflammatory reactions of the hosts. This review, focusing on the Mexican experience, describes and interprets the heterogeneity of NC as the result of different combinations among factors associated with the parasite, host and environment. The review may serve to foster similar descriptive efforts in other endemic areas of the world in order to facilitate the identification of the distinct factors that participate in the complex pathogenesis and diverse clinical outcomes of NC. In particular, it is necessary to understand the precise physiopathology of the inflammatory reaction associated with NC, as inflammation is one of the characteristics of those NC cases that are clinically more severe and less responsive to current treatments. Devising new medical interventions through the use of molecular regulators of the innate and adaptive immune responses of the host is a largely unexplored approach that could improve the existing forms of treatment.

    Intramuscular myxomas are benign and rare tumors that affects predominantly the lower limbs. The association of myxomas and fibrous dysplasia, usually polyostotic, is rarer. This association is known as Mazabraud's syndrome, of which about 81 cases have been described in the literature. We present a new case of this uncommon association to emphasise the importance of recognizing this syndrome in the diagnosis and appropriate management of the patient.

    Lymphangiomatosis confined to the spleen is a very are condition. The authors in this article describes one new case and briefly reviews the literature. In this case, after the exclusion of an hydatidosis of the spleen, a total splenectomy was performed. The histologic findings confirmed the lymphangiomatosis of the spleen. The authors emphasize the surgical strategy in splenic lymphangiomyomatosis, infact the total splenectomy is mandatory, because the splenic parenchyma is nearly completely substitute by the cysts. For this reason is preferably, before surgery, to perform the antibateric profilaxis against the OPSI.

    2011-07-01

    In the summer of 2009, we began full body computed tomography (CT) scanning of the pre-embalmed cadavers in the University of Michigan Medical School (UMMS) dissection lab. We theorized that implementing web-based, self-guided clinical cases based on postmortem CT (PMCT) scans would result in increased student appreciation for the clinical relevance of anatomy, increased knowledge of cross-sectional anatomy, and increased ability to identify common pathologies on CT scans. The PMCT scan of each cadaver was produced as a DICOM dataset, and then converted into a Quicktime movie file using Osirix software. Clinical cases were researched and written by the authors, and consist of at least one Quicktime movie of a PMCT scan surrounded by a novel navigation interface. To assess the value of these clinical cases we surveyed medical students at UMMS who are currently using the clinical cases in their coursework. Students felt the clinical cases increased the clinical relevance of anatomy (mean response 7.77/10), increased their confidence finding anatomical structures on CT (7.00/10), and increased their confidence recognizing common pathologies on CT (6.17/10). Students also felt these clinical cases helped them synthesize material from numerous courses into an overall picture of a given disease process (7.01/10). These results support the conclusion that our clinical cases help to show students why the anatomy they are learning is foundational to their other coursework. We would recommend the use of similar clinical cases to any medical school utilizing cadaver dissection as a primary teaching method in anatomy education.

    With a self-made near-infrared analytical instrument to blood and oxygen parameters in human brain, 80 cases in which 20 are healthy persons and 30are anaesthetised cases and others are patients with heart function lack is taken to examine, and the data of blood and oxygen in brain tissue were collected and analyzed by the method of power spectrum and correlation function. The results indicate that: (1) The average brain oxygen saturation of healthy persons and anaesthetised cases is about 80%, in accord with normal parameter of physiology. Contrastively, the average brain oxygen saturation of patients with heart function lack is 72. 8%, which is obviously less than that of healthy persons and anaesthetised cases. The probability of medical statistics is less than 0. 01. (2) The shapes of wave of brain blood and oxygen for the healthy person and the anaesthetised case reveal small periodical fluctuations with stable shape and base line, and the trend of increase or decrease of blood and oxygen parameters in brain tissue is synchronous and a phase reversal, but for the patient with heart function lack in a brain oxygen lack state, the shapes of wave are irregular. This is a hint that near infrared light passing through tissue can reflect the intuitionistic change of brain blood and oxygen parameters. (3) The power spectra of brain blood and oxygen for the healthy person and the anaesthetised case has a clear main peak, narrow bandwidth and perfect superposition each other, but the power spectra for the patient with heart function lack in a brain oxygen lack state is on the contrary. (4) The average cross correlation coefficient of brain blood and oxygen for healthy persons and anaesthetised cases is -0. 9825±0. 1027 close to -1. But the average cross correlation coefficient for patients with heart function lack in a brain oxygen lack state is merely -0. 8923± 0. 1035 which is obviously greater than -1 and the probability of medical statistics is less than 0. 01

    Syphilis has a broad spectrum of clinical manifestations, and the cerebral gumma is a kind of neurosyphilis which is rare and can be cured by appropriate antibiotic treatments. However, in clinical practices, diagnosis of cerebral syphilitic gumma is often difficult because imaging and laboratory findings revealed elusive results. Herein, we present a rare case of neurosyphilis presenting as cerebral gumma confirmed by histopathological examination, and positive serologic and cerebrospinal fluid analyses. This case report suggests that cerebral gumma should be considered as possible diagnosis for human immunodeficiency virus-negative patients with space-occupying lesion of the brain. And this case also provides importance of clinical suspicions in diagnosing neurosyphilis because syphilis serology is not routinely tested on patients with neurologic symptoms.

    Human trafficking victims experience extreme exploitation and have unique health needs, yet too often go undetected by physicians and providers in the Emergency Department (ED). We report a clinical case of human trafficking of a white, English-speaking United States citizen and discuss the features of presentation and treatment options for human trafficking victims upon presentation to the ED. A 29-year-old woman with a past medical history significant for intravenous drug abuse and recent relapse presented to the ED after a reported sexual assault. The patient was discharged that evening and returned to the ED the following day acutely suicidal. The patient divulged that she had been kidnapped and raped at gunpoint by numerous individuals as a result of a debt owed to her drug dealers. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Many human trafficking victims present to an ED during the course of their exploitation. To that end, EDs provide one of a limited set of opportunities to intervene in the human trafficking cycle of exploitation, and physicians as well as other ED staff should be equipped to respond.

    Monoclonal antibodies are large molecules with complex structure and functions. They have a wide application for treatment of a broad range of chronic diseases and represent the largest class of biotherapeutic products. Given that biotherapeutic products may induce unwanted humoral and/or cellular immune responses in recipients, it is essential to investigate the immunogenicity of a product prior to licensure. The immune response is influenced by many factors and data generated in the pre-licensure studies are usually somewhat difficult for regulatory review. The knowledge and expertise required for this requires a thorough understanding of animal and human immunology as well as specific product characteristics, including mechanism of action, antibody assays and assessment of results in a given clinical context. The appropriate interpretation of immunogenicity data is of critical importance for defining the safety profile of a monoclonal antibody. Two case studies described in this paper were prepared to mimic a real situation in which regulators need to evaluate immunogenicity studies conducted by manufacturers of monoclonal antibody products. The specific objective of the case studies was to illustrate assessment of unwanted immunogenicity and the important factors that need to be considered in this context. Regulators and manufacturers who attended the World Health Organization (WHO) implementation workshop on Evaluation of Biotherapeutic Products, held in Seoul, Republic of Korea, in May 2014, participated in the case studies and provided valuable input. This article outlines the main aspects of immunogenicity discussed in these case studies and a summary of the lessons learned at this occasion. Copyright © 2015 The Authors.

    Background Malignant hyperthermia (MH), manifesting as MH crisis during and/or after general anesthesia, is a potentially fatal disorder in response to volatile anesthetics and depolarizing muscle relaxants.Though typical features of MH episode can provide clues for clinical diagnosis, MH susceptibility is confirmed by in vitro caffeine-halothane contracture test (CHCT) in western countries.It is traditionally thought that MH has less incidence and fewer typical characteristics in Chinese population than their western counterparts because of the different genetic background.In this study, we investigated the clinical features of MH in Chinese cases and applied the clinical grading scale and CHCT for diagnosis of MH.Methods A cluster of three patients with MH, from January 2005 to December 2007, were included in the study.Common clinical presentations and the results of some lab examinations were reported in detail.The method of the clinical grading scale of diagnosis of MH was applied to estimate the qualitative likelihood of MH and predict MH susceptibility.Muscle fibers of femoral quadriceps of the patients were collected and CHCT was performed to confirm the diagnosis of MH.Results The clinical grading scales of diagnosis of the disease for these cases were all ranked grade D6, suggesting almost diagnosed ones.And the results of caffeine test were positive correspondingly, indicating that the patients should be diagnosed as MH susceptibility (MHS) according to diagnostic criteria of the North America MH group, which were already confirmed by clinical presentations and biochemical results.Conclusions These Chinese cases manifest as MH crisis.The clinical grading scale of diagnosis of MH may provide clues for clinical diagnosis.CHCT can also be used in confirming diagnosis of MH in Chinese cases though they have different genetic background from their western counterparts.

    Seventeen patients with multiple exostoses were examined on bone scintigraphy. Inheritance was recognized on seven patients (41%). Onset age of 15 patients was under 20 years old and 10 patients were under 10. The number of lesions was 211 and they were usually recognized at metaphyses of long bones. The degree of accumulation was classified into four grades: 0 (non increased), 1 (slightly-mild), 2 (moderate), and 3 (strong). One hundred and fifty-three lesions (73%) did not show definite increased activity (Grade 0, 1). Grade 3 included 14 lesions and they tended to be strongly calcified on X-P. This disease was said to transform into chondrosarcoma in 10 to 20%. Transformation was said to occur preferably in adults at heavily calcified lesion or one which showed irregularly thick hyaline cartilage. Such lesions showed more increased accumulation than normal bones. In our cases three cases were resected for this reason but turned out to be benign histologically. One case showed malignant transformation. In this case, a large malignant tumor replaced the parent bone and bone scan showed the cold lesion. Bone scintigraphy was considered useful to evaluate the biological activity of multiple exostoses. (author).

    1985-10-01

    In summary, we have described our method of treating phosgene inhalation injury. We have presented two serious cases in detail which demonstrate that survival was associated with aggressive therapy. Several points should be mentioned. The pulmonary edema and resulting fluid and foam production can be so copious as to overwhelm efforts to place an endotracheal tube. The solution is early intubation by the nearest experienced person at the first hint of edema or pulmonary failure. Adequate support of the patient's blood volume is imperative to avert hypovolemic shock and renal failure. A balloon flotation catheter is desirable to monitor pulmonary wedge pressure and avoid overload. Follow-up pulmonary function studies and chest x-rays are recommended 2-3 months after hospital discharge. We have not yet found a reliable test to determine which cases will progress to pulmonary edema. The LDH appears to be the only consistently elevated sign in more serious cases. Finally, we would like to make a plea for the sharing of information from instances of fatal phosgene injury so that the facts can be studied and applied to future cases.

  1. Bilateral Chondroepitrochlearis Muscle: Case Report, Phylogenetic Analysis, and Clinical Significance

    Directory of Open Access Journals (Sweden)

    Sujeewa P. W. Palagama

    2016-01-01

    Full Text Available Anomalous muscular variants of pectoralis major have been reported on several occasions in the medical literature. Among them, chondroepitrochlearis is one of the rarest. Therefore, this study aims to provide a comprehensive description of its anatomy and subsequent clinical significance, along with its phylogenetic importance in pectoral muscle evolution with regard to primate posture. The authors suggest a more appropriate name to better reflect its proximal attachment to the costochondral junction and distal attachment to the epicondyle of humerus, as “chondroepicondylaris”; in addition, we suggest a new theory of phylogenetic significance to explain the twisting of pectoralis major tendon in primates that may have occurred with their adoption to bipedalism and arboreal lifestyle. Finally, the clinical significance of this aberrant muscle is elaborated as a cause of potential neurovascular entrapment and as a possible hurdle during axillary surgeries (i.e., mastectomy.

Chest HRCT scan showed areas of ground glass attenuation, consolidation, and traction bronchiectasis in bilateral bases of lungs. BAL fluid test and transbronchial lung biopsy failed to offer insightful evidence for diagnosis. She was clinically diagnosed with acute interstitial pneumonia (AIP. Treatment with mechanical ventilation and intravenous application of methylprednisolone (80 mg/day showed poor clinical response and thus was followed by steroid pulse therapy (500 mg/day, 3 days. However, she died of respiratory dysfunction eventually. Autopsy showed diffuse alveolar damage associated with hyaline membrane formation, pulmonary interstitial, immature collagen edema, and focal type II pneumocyte hyperplasia.

  3. CLINICAL CASE OF RARE TYPE V OSTEOGENESIS IMPERFECTA

    Directory of Open Access Journals (Sweden)

    G. T. Yakhyayeva

    2015-01-01

    Full Text Available Osteogenesis imperfecta, also known as the brittle bone disease, is a clinically heterogenic hereditary connective tissue disease characterized by brittle bones and high risk of skeletal bone fractures. Other observable symptoms, such as deformities of limb and spinal bones, blue sclerae, dentinogenesis imperfecta and progressive hearing loss vary in severity depending on the type of the disease. According to the original classification by D.O. Silence (1979, there are 4 types of osteogenesis imperfecta; however, the number thereof has multiplied due to discovery of new disease-inducing mutations. Type V osteogenesis imperfecta is distinguished by characteristic clinical radiographic symptoms; also, patients with this type of the disease do not feature a type I collagen gene mutation. Nevertheless, all types of osteogenesis imperfecta, including type V, are characterized by high bone brittleness, frequent fractures and further bone deformities, which is the most common cause of incapacitation of the patients.

    2014-07-01

    Full Text Available ertussis is an endemic disease in our population. Every 3 to 4 years, pertussis has an epidemic pattern even in countries with good health conditions. Antipertussis vaccine first dose is adminis- tered at the age of 2 months; a second and third dose are given at 4 and 6 months of age. This vaccine has an 8 to 10 year protective effect, for which reason it is suggested that pregnant women in the third trimester should be vaccinated in order to prevent pertussis in newborns. It should also be administered to older people to avoid turning them into asymptomatic carriers. Clinic manifestations are easily identifiable due to respiratory symptoms, especially to the particular characteristics of the cough. The diagnosis is supported by the presence of leukocytosis (predominantly lymphocytes and by certain thoracic radiologic findings. The diagnosis is confirmed with a positive culture for Bordetella pertussis or with a polymerase chain reaction (PCR. In a non complicated clinic course macrolides are still the best therapeutic choice. Nonetheless clinic observation is highly recom- mended in order to avoid complications. Redefinition of vaccine programs against Bordetella pertussis in Mexican population is recommended and also to notify the presence of the disease to the corresponding health authorities.

  9. Health-seeking behaviour of human brucellosis cases in rural Tanzania

    2007-11-01

    Full Text Available Abstract Background Brucellosis is known to cause debilitating conditions if not promptly treated. In some rural areas of Tanzania however, practitioners give evidence of seeing brucellosis cases with symptoms of long duration. The purpose of this study was to establish health-seeking behaviour of human brucellosis cases in rural Tanzania and explore the most feasible ways to improve it. Methods This was designed as a longitudinal study. Socio-demographic, clinical and laboratory data were collected from patients who reported to selected hospitals in rural northern Tanzania between June 2002 and April 2003. All patients with conditions suspicious of brucellosis on the basis of preliminary clinical examination and history were enrolled into the study as brucellosis suspects. Blood samples were taken and tested for brucellosis using the Rose-Bengal Plate Test (RBPT and other agglutination tests available at the health facilities and the competitive ELISA (c-ELISA test at the Veterinary Laboratory Agencies (VLA in the UK. All suspects who tested positive with the c-ELISA test were regarded as brucellosis cases. A follow-up of 49 cases was made to collect data on health-seeking behaviour of human brucellosis cases. Results The majority of cases 87.7% gave a history of going to hospital as the first point of care, 10.2% purchased drugs from a nearby drug shop before going to hospital and 2% went to a local traditional healer first. Brucellosis cases delayed going to hospital with a median delay time of 90 days, and with 20% of the cases presenting to hospitals more than a year after the onset of symptoms. Distance to the hospital, keeping animals and knowledge of brucellosis were significantly associated with patient delay to present to hospital. Conclusion More efforts need to be put on improving the accessibility of health facilities to the rural poor people who succumb to most of the diseases including zoonoses.

    2012-06-01

    Full Text Available Abstract Background Chronic lymphocytic leukemia (CLL is the rarest adult leukemia in Japan, whereas it is the most common leukemia in the Western world. Recent studies from the United States and Germany suggest a possible etiological association between Merkel cell polyomavirus (MCPyV and CLL, although no data have been reported from Eastern countries. To increase the volume of relevant data, this study investigated the prevalence and DNA loads of MCPyV and human polyomavirus 9 (HPyV9, another lymphotropic polyomavirus, in Japanese CLL cases. Findings We found that 9/27 CLL cases (33.3 % were positive for MCPyV using quantitative real-time polymerase chain reaction analysis. The viral DNA loads ranged from 0.000017 to 0.0012 copies per cell. All cases were negative for HPyV9. One MCPyV-positive CLL case was evaluated by mutational analysis of the large T (LT gene, which indicated the presence of wild-type MCPyV without a nucleotide deletion. DNA sequence analysis of the entire small T (ST gene and the partial LT gene revealed that a Japanese MCPyV isolate, designated CLL-JK, had two nucleotide gaps when compared with the reference sequence of the North American isolate MCC350. Conclusions This study provides the first evidence that MCPyV is present in a subset of Japanese CLL cases with low viral DNA loads. MCPyV and HPyV9 are unlikely to contribute directly to the development of CLL in the majority of Japanese cases. MCPyV isolated from the Japanese CLL cases may constitute an Asian group and its pathogenicity needs to be clarified in future studies.

    2009-07-01

    Full Text Available Abstract Background The development of cell-based therapeutics for humans requires preclinical testing in animal models. The use of autologous animal products fails to address the efficacy of similar products derived from humans. We used a novel immunodeficient rat carotid injury model in order to determine whether human cells could improve vascular remodelling following acute injury. Methods Human CD34+ cells were separated from peripheral buffy coats using automatic magnetic cell separation. Carotid arterial injury was performed in male Sprague-Dawley nude rats using a 2F Fogarty balloon catheter. Freshly harvested CD34+ cells or saline alone was administered locally for 20 minutes by endoluminal instillation. Structural and functional analysis of the arteries was performed 28 days later. Results Morphometric analysis demonstrated that human CD34+ cell delivery was associated with a significant reduction in intimal formation 4 weeks following balloon injury as compared with saline (I/M ratio 0.79 ± 0.18, and 1.71 ± 0.18 for CD34, and saline-treated vessels, respectively P Conclusion Delivery of human CD34+ cells limits neointima formation and improves arterial reactivity after vascular injury. These studies advance the concept of cell delivery to effect vascular remodeling toward a potential human cellular product.

    2015-11-01

    Recently, a number of phage therapy phase I and II safety trials have been concluded, showing no notable safety concerns associated with the use of phage. Though hurdles for efficient treatment remain, these trials hold promise for future phase III clinical trials. Interestingly, most phage formulations used in these clinical trials are straightforward phage suspensions, and not much research has focused on the processing of phage cocktails in specific pharmaceutical dosage forms. Additional research on formulation strategies and the stability of phage-based drugs will be of key importance, especially with phage therapy advancing toward phase III clinical trials.

    Full Text Available Dysplastic coxarthrosis is dominate among children orthopedic cases, and its surgical alignment continues to be peracute. Despite the application of advanced therapies and medical treatment, the patients of surgical state case constitute a significant percentage of the total patient number, i. e. from 19 to 35 %. In this article a detailed literature review of surgical alignment methods for deficiency acetabular roof by applying different implants has been described. The authors have proposed applying titanium nickelide materials in the surgical alignment method, as such materials possess the following properties: high corrosion stability, full compatibility with the body tissues, as well as, sufficient porosis providing radial border structure regeneration of acetabular roof, which in its turn, improves the support ability of extermity. In the event of progression of coxarthrosis iliac segment is reserved for the upcoming replacement.

    This paper reports the results of non-operative therapy for cholelithiasis in 105 cases using He-Ne laser lithotripsy and a high fat diet, as well as Chinese and Western medicine. There were 32 male and 73 female patients ages 11 - 67 years (with an average of 41.2 years). All cases were confirmed by either B mode sonography or cholangiography. This paper presents the technique of treatment, its indications, contraindications, and therapeutic results. The results reveal a cure rate of 20% (21/105), satisfactory in 72.4% (76/105), and failed in 7.6% (8/105). Successful passage of gallstones was found in 92.4% and 52 samples of gallstones were examined qualitatively. The results show that He-Ne laser irradiation in the treatment of cholelithiasis is associated with neither pain, side-effect, nor cross infection, and is readily accepted by the patients.

    The keratocystic odontogenic tumor is a benign odontogenic cystic neoplasia characterized by its thin, squamous epithelium with superficial parakeratosis. It has the potential for infiltration and local aggressiveness and has a high rate of recurrence. This neoplasia is predominantly found in males and people of white origin. The mandible is the most frequently involved site, in particular the third molar region, mandibular angle, and ramus. It has a mandible-maxilla ratio of 2:1. Only about twenty cases of peripheral keratocystic odontogenic tumors (PKCOT) have been reported in the international literature. This study presents a case of PKCOT localized in the anterior region of the maxilla, on the vestibular side of the upper left lateral incisor and the upper left canine. The diagnosis and treatment procedures, as based on the literature, are also discussed. Key words:Odontogenic cysts, odontogenic tumors, keratocyst, keratocystic odontogenic tumor. PMID:28149484

The case was analyzed based on the framework of Analytical Psychology, founded mainly on Carl Gustav Jung. Psychological counseling sessions were held, and after the sessions, theoretical approaches have been made based on the material presented by the patient. The interventions were performed with the goal of enabling the patient and insights she sought other ways to position themselves in the world and to relate to the people around. Over the course of the sessions, the patient was able to construct a context in which allow and deny more in accordance with their abilities and possibilities.

    Composite pheochromocytoma-ganglioneuroma is extremely rare. We described two cases of composite pheochromocytomas in the adrenal medullar. Case 1 was a 70-year-old male presenting with lower abdominal pain and normal blood electrolytes. Case 2 was a 48-year-old female with palpitation and back tenderness. Biochemical investigations showed hypocalcium, hypokalemia and high level of vma. The histological images and the immunohistochemical staining demonstrated the two cases composed of pheochromocytoma and ganglioneuromoma components. Ganglioneuroma component in case 2 accounted for more proportion than that in case 1. We speculated that the varied clinical symptoms were related with the diverse proportions in composite pheochromocytome-ganglioneuroma.

    Full Text Available Neck cysts are rather commonly encountered in the practice of a surgeon, including an oncologist, who treats diseases of the head and neck. At the same time there are rare involvements of the organs and soft tissues of the neck. In particular, echinococcosis of neck soft tissues is an unusual site for hydatid cyst. Accounts of this involvement are found only as single communications in the literature. The presented case of hydatid cyst illustrates a variety of neck abnormalities.

    Full Text Available We evaluated 44 patients with tics and Tourette's syndrome (TS emphasising the age of onset of symptoms, sex, classification and localization of tics, associated symptoms and signs and comorbidities. Thirty-three patients (75.2% had TS defined criteria whereas 10 (22.7% had chronic motor and/or vocal tics. Simple motor tics were found in 43 cases (97.7%, mainly affecting the eyes (43.2%, mouth (43.2%, face (34.1%. Simple vocal tics occurred in 33 (75%. Coprolalia was found in just 6 cases (13.6% and copropraxia in just 2 (4.5%. Obsessive compulsive disorder and/or symptoms were found in 26 cases (59.1% and attention deficit in 17 (38.6%. Eighteen patients (40.9% had other disorders, such as alcoholism, tabagism, drug abuse, affective disorders, anxiety, sleep and learning disorders. The data obtained are similar to those found by other authors. We highlight the low frequency of coprolalia, as well as the associated neuropsychiatric disorders.

    Cervical tuberculous lymphadenitis is sometimes difficult to differentiate from sarcoidosis. We treated 10 patients with cervical tuberculous lymphadenitis from April 2002 to December 2011. Their ages ranged from 42 to 78 years old (mean 63.2 years), and the male-to-female ratio was 4: 6. All patients presented to our hospital with the chief complaint of a cervical mass. All patients underwent open biopsy of the cervical lymph nodes, and 8 patients were diagnosed histopathologically as having cervical tuberculous lymphadenitis. In the remaining 2 patients, caseous necrosis could not be recognized histopathologically and they were diagnosed as having sarcoidosis. However 8 weeks later, the culture of the acid-fast bacilli turned positive, and the diagnosis was corrected to cervical tuberculous lymphadenitis. In our cases, the culture of acid-fast bacilli was positive in 6 out of 9 cases (66.7%), and TB-PCR was positive in 4 out of 9 cases (44.4%). These results show that sensitivity of individual tests is rather low. For the diagnosis of cervical tuberculous lymphadenitis, it is important to suspect this disease from the findings of the sedimentation rate, tuberculin test, and ultrasonography with fine needle aspiration cytology. On performing an open biopsy of the cervical lymph nodes in the suspected patients, it is essential to combine histopathological study, TB-PCR and the culture of the acid-fast bacilli simultaneously.

    Full Text Available Objective: To report clinical, virological, and epidemiological features of the first death caused by a H5N6 avian influenza virus in Yunnan Province, China. Method: The case was described in clinical expression, chest radiography, blood test and treatment. Real-time RT-PCR was used to detect H5N6 virus RNA in clinical and environment samples. Epidemiological investigation was performed including case exposure history determinant, close contacts follow up, and environment sample collection. Results: The patient initially developed sore throat and coughs on 27 January 2015. The disease progressed to severe pneumonia, multiple organ dysfunction syndrome, and acute respiratory distress syndrome. And the patient died on 6 February. A highly pathogenic avian influenza A H5N6 virus was isolated from the tracheal aspirate specimen of the patient. The viral genome analyses revealed that the H5 hemmagglutinin gene belongs to 2.3.4.4 clade. Epidemiological investigation showed that the patient had exposure to wild bird. All close contacts of the patient did not present the same disease in seven consecutive days. A high H5 positive rate was detected in environmental samples from local live poultry markets. Conclusion: The findings suggest that studies on the source of the virus, transmission models, serologic investigations, vaccines, and enhancing surveillance in both humans and birds are necessary.

    Full Text Available BACKGROUND: To improve the early identification of autoimmune pancreatitis in China by a retrospective analysis of clinical data from AIP patients. METHODOLOGY/PRINCIPAL FINDINGS: The analysis included 36 patients admitted by the surgery department of our hospital from January 2003 to October 2011 whose postoperative pathological confirmations were consistent with the histological criteria of Honolulu Consensus Document. The clinical phenotypes associated with the histopathologic patterns of LPSP and IDCP were referred to as type 1 and type 2 of AIP, respectively. A retrospective analysis of clinical features, serological data, pathological findings and imageological records was performed in line with the subtypes of AIP. Type 1 showing a sex predilection (males was commonly more dominant than type 2 in all AIP. Type 2 without a gender predilection was, on average, a decade younger than type 1. Type 1 was inferior to type 2 in ALT, ALP and γ-GT with statistical significance (P = 0.044, 0.025 and 0.013. Type 1 was inferior to type 2 in AST with difference close to statistical significance (P = 0.072. Histopathology revealed frequent lymphoplasmacytic infiltration with less frequent infiltration of neutrophils, eosinophils and fibroblasts. Diffuse and intensive interstitial fibrosis could be seen. The changes of pancreatic head were more frequently seen in type 2 than in type 1 (P = 0.05. Plasma cells staining of IgG4 at a density of over 30 or more cells per high-power field appeared to be a specific finding in China with type 1. Imageology found a diffusely or focally enlarged pancreas, most frequently a mass or enlargement in the pancreatic head, characteristic capsule-like rim, calcification or pancreatic calculus and cystic degeneration. CONCLUSIONS/SIGNIFICANCE: AIP is a unique type of chronic pancreatitis and has distinctive serological, pathological and imageological characteristics, which should be used for differentiation

    Infectious bovine keratoconjunctivitis (IBK) is a painful ocular disease affecting cattle worldwide. The publications documenting this condition focus on what is the accepted cause of IBK--Moraxella bovis. This article draws on experience and recorded data made at the time of the initial examination and follow-up visits. Laboratory culture of ocular swabs was undertaken where appropriate. Diagnosis of IBK is usually based on clinical signs, environment, and history. Misdiagnosis of the organisms involved is a genuine possibility. This article focuses on recent outbreaks of bovine ocular disease in the United Kingdom in three counties over a 12-month period.

    Lyme disease which is caused by the spirochete Borrelia burgdorferi, is a multisystemic disease that involves skin, joints, cardiovascular and central nervous system, leading to chronic inflammatory response and late complications. First lyme cases have been reported after 1990's in Turkey and the spirochete was isolated from the tick vectors. In this case series three human Lyme cases confirmed with not only serological tests but also growth in Barbour-Stoenner-Kelly medium were presented for the first time in Turkey. Two of these three cases were residents in Istanbul while the third one has acquired the infection in USA (imported case). First case was a previously healthy 46 years old male, admitted to the state hospital with the complaints of diarrheae, chills, nausea, vomiting, cough, sputum production and widespread myalgias. The patient was a chronic alcohol consumer with a history of frequent visits to the forest areas. The laboratory test results revealed hepatonephritis-like clinical picture and pulmonary involvement. Leptospira IgM and Borrelia IgM antibodies were detected in the serum by ELISA and both of the agents were isolated in the blood cultures of the patient. This case was then diagnosed as Lyme disease with leptospirosis co-infection. The second case was a 32 years old female who suffered from Bell's palsy for the last 15 days. Cranial magnetic resonance imaging showed a nodular lesion at globus pallidus. Since the patient had a history of tick-bite, further testing was done for Lyme disease. Borrelia IgM and IgG antibodies were found negative, however, Borrelia was isolated from the cerebrospinal fluid sample. The third patient was a 68 years old female who had recently travelled to USA and exposed to a tick-bite in a recreational area. She suffered from nausea, vomiting, myalgia and cutaneous lesions compatible with erythema chronicum migrans. Samples taken from the skin lesions revealed growth of Borrelia. As far as the current literature is

    Full Text Available Cutaneous dirofilariasis is a parasitic disease caused by the mosquito-borne filarial nematodes Dirofilaria (Nochtiella repens, living in the subcutaneous tissue of dogs, cats, wild carnivores, and humans. Cases have been recently reported also from Germany, Czech Republic, Hungary, Ukraine, Russia, Austria, Switzerland, France, The Netherlands, and the Middle East. D. repens is not widely known to cause chronic pruritic dermatitis in animals. Dermatological signs observed in 100 canine clinic cases were pruritus (100%, erythema (79%, papulae (62%, focal or multifocal alopecia (55%, hyperkeratosis (18%, crusting (14%, nodules (12%, acantosis (5%, and eczema (3%. Signs other than dermatological were conjunctivitis (46%, anorexia (35%, vomiting (26%, fever (25%, lethargy (20%, and lymph-adenomegaly (10%. A case imported from Italy to Dubai is described. The opportunistic role of D. repens might explain the presence of asymptomatic carriers, the concurrent observation of nondermatological signs, and the development of dermatitis in a subgroup of parasitized dogs.

    Full Text Available We describe the validation process of a case formulation protocol, based on the theoretical perspective of Behavior Analysis, in order to contribute to the development of a case formulation model aimed to organize the information coming from evaluation, to reduce clinical judgment bias, and to orient the clinical intervention towards a coherent and consistent way with the analysis categories belonging to the field of Psychological Wellbeing. Validity was defined as a function of the use of a single case designwith a time series methodology and the internal validity of the formulations, based on criteria of consistency among the categories and the descriptive and explicative hypotheses, and among these and the intervention plan.The clinical formulation process was finished with six cases, taking the intervention efficacy as the validity criterion. Results point to the high level of inference and hypotheses based on clinical judgment rather than on empirical evidences.

    Depressive personality disorder (DPD) is highly studied and common in clinical settings. Nevertheless, it is rife with controversies and often overshadowed by major depression and dysthymia with which it shares many similarities but also is clinically distinct. Possibly as a result, DPD is underdiagnosed and misunderstood in clinical care. Thus the goal of this practice review is to present a case from psychiatric clinical work illustrating how DPD may be commonly overlooked in routine care, and how the conceptualization of this case and its treatment plan changed course once DPD was considered by treating staff, ultimately contributing to the successful outcome of the case. Questions elicited by the case are subsequently discussed in the context of the empirical literature on DPD, allowing for a clearer picture to emerge on DPD and its role in the development, course, and treatment of depression.

    Nine patients with symptoms and signs of Refsum's disease are reported. In 6 a systemic accumulation of phytanic acid was demonstrated, together with low phytanic acid oxidase activity in skin fibroblasts in 5 of them. In 3, no disorder of phytanic acid metabolism was demonstrated. In 3, the diagnosis was made during the pre-clinical period. The disease seems more frequent in Northern France, which agrees with the hypothesis of a genetic mutation which would have taken place in Scandinavia some centuries ago and was subsequently spread by the Vikings. The effects of a dietary treatment on serum phytanic acid levels and clinical disorders are reported. The general condition of the patients improved remarkably but only partially. The diet is unpalatable and in some patients the level of serum phytanic acid increased, due to the mobilization of body fat. Patients with very high levels of phytanic acid might be initially treated by plasmapheresis. For the same reason, the diet should supply enough calories to keep body weight unchanged, and body weight loss whatever its cause should be avoided.

MethodsA retrospective analysis was performed on the clinical records of 216 patients with acute cholecystitis who underwent LC in Qingpu Branch of Zhongshan Hospital, Fudan University from January 2010 to January 2013. LC was performed under intubation general anaesthesia, with three holes conventionally and four holes if necessary. After operation, the drainage tube was placed for 1-3 d, and antibiotics were administered for 3-5 d. The time of operation, length of postoperative hospital stay, and incidence of postoperative complications were determined. All patients were followed up for at least 0.5 year after operation. ResultsLC was successfully performed in 188 (87.0% of all patients; 28 (13.0% of all patients were converted to open surgery. The mean time of operation was 62.00±11.27 min; the mean length of hospital stay was 4.60±2.16 d; the incidence of postoperative complications was 2.3%(5/216. All patients were cured and discharged. During follow-up, no patients developed other complications and all recovered well. ConclusionLC is safe and feasible in the treatment of acute cholecystitis. Correct manipulation of the Calot's triangle and proper abdominal drainage are the key to successful operation.

    Full Text Available Introduction: Gout is an increasingly common medical problem. The traditional risk factors of male sex and high red meat or alcohol consumption have been joined with newer risks such as increased life expectancy, and the metabolic syndrome (hypertension, diabetes, dyslipidaemia, truncal obesity. Methods: This was a retrospective study to determine the epidemiology, clinical features, associated conditions as well as renal related conditions in existing gout patients followed-up in Rheumatology outpatient clinic, Hospital Tuanku Ja’afar, Seremban. Results: Over a three month period, we identified 54 gouty patients on our follow-up, the majority being male, Malay ethnicity, withthe age of onset in the third and fourth decades of life. Commonly associated risk factors were hypertension, hyperlipidaemia and obesity. However, underlying history of diabetes mellitus, alcohol consumption, and family history were not commonly associated with gout in our group of patients. Half of our patients had at least two or more joints involvement. About half of the patients with tophaceous gout had renal impairment. Conclusion: Our series of gout patients highlight the high prevalence of cardiovascular risk factors. The high prevalence of tophi and renal impairment is a cause for concern.

    This is the case of a 61-year-old patient woman that visits her nurse in Primary Health Care to get the control of blood pressure and glycemia. In the last two years has suffered the loss of her husband and of two brothers beside having lived through other vital stressful events that have taken her to a situation of complicated grief. The care plan is realized using the M. Gordon assessment system and standardized languages NANDA, NOC and NIC. The principal aims were the improvement of the depression level and the improvement in the affliction resolution. As suggested interventions were proposed to facilitate the grief and the derivation to a mental health unit. A follow-up of the patient was realized in nursing consultation at Primary health care to weekly intervals, in the beginning, and monthly, later. The evaluation of the care plan reflects an improvement in the criteria of Prigerson's complicated grief; an increase of the recreative activities; the retreat of the mourning that still she was guarding; as well as an improvement in the control of the blood pressure numbers. The attention of nurses before a case of complicated grief turns out to be complex. Nevertheless the suitable accomplishment of certain interventions orientated to facilitating the grief, with a follow-up in consultation, shows the efficiency. The difficulty in the boarding of the psychosocial problems meets increased at the moment of are necessary the nursing diagnostics adapted for every individual case. The work in group between nurses could improves the consensus.

I describe the case of a "second opinion" consultation in the care of a patient with advanced cancer for whom treatment was futile. While the initial ethics consultation, performed by a colleague, let to a recommendation that some may deem ethical, the process failed to involve key stakeholders and failed to explore the underlying values and reasons for the opinions voiced by various stakeholders. The process of mediation ultimately led to creative solutions in which all stakeholders could reach consensus on a plan of care.

    In this paper, a Jungian understanding of cultural factors influencing individual analysis is illustrated with the case of a patient suffering from panic attacks. The analysis revealed that, in addition to the patient's personal background, the collectivistic attitudes of the Soviet culture, which had a moulding effect on the patient in his childhood and obstructed his individuation, should be taken into account. The concepts of the totalitarian object and the Russian cultural complex encompassing a grandiosity pole and an inferiority pole are used to explore the patient's condition, and the crucial role of creating mutual language with the patient is outlined. © 2016, The Society of Analytical Psychology.

    Full Text Available Glanzmann's thrombasthenia (GT is a rare, genetically inherited platelet disorder in which the platelet glycoprotein IIb/IIIa (GP IIb/IIIa complex is either deficient or, dysfunctional. The incidence is about 1 in 1,000,000. This case report deals with a 4 year-old girl diagnosed with GT presenting with dental caries and periapical lesions in the primary mandibular first molars. To provide the best care, an interdisciplinary approach was followed by a team consisting of pediatric dentists, pediatricians and anesthesiologists. Complete oral rehabilitation was planned under general anesthesia which included extractions, multiple esthetic restorations and space maintainers with the utmost care to prevent unwarranted bleeding.
