    Full Text Available Antiphospholipid antibodies (aPL represent a heterogeneous group of antibodies that recognize various antigenic targets including beta2 glycoprotein I (β2GPI, prothrombin (PT, activated protein C, tissue plasminogen activator, plasmin and annexin A2. The most commonly used tests to detect aPL are: lupus anticoagulant (LAC, a functional coagulation assay, anticardiolipin antibody (aCL and anti-β2GPI antibody (anti-β2GPI, which are enzyme-linked immunoassay (ELISA. Clinically aPL are associated with thrombosis and/or with pregnancy morbidity. Apparently aPL alone are unable to induce thrombotic manifestations, but they increase the risk of vascular events that can occur in the presence of another thrombophilic condition; on the other hand obstetrical manifestations were shown to be associated not only to thrombosis but mainly to a direct antibody effect on the trophoblast.

    Full Text Available Background: Plant-origin foods are among the most important sources of food allergic reactions. An increase in the incidence of sesame seed allergy among children and adults has been reported in recent years. The aim of this preliminary study was to investigate the prevalence, importance and clinical manifestations of sesame allergy among Iranian patients.Methods: In a cross-sectional survey, 250 patients with suspected IgE-mediated food allergies completed a questionnaire and underwent skin prick tests with sesame extract as well as cross-reacting foods (walnut, soya and peanut. Total IgE and sesame-specific IgE levels were measured. Patients with positive skin test reactions and/or IgE specific for sesame without clinical symptoms were considered sensitive to sesame. The patients who also had clinical symptoms with sesame consumption were diagnosed as allergic to sesame.Results: Of the 250 patients enrolled in this study, 129 were male and 121 female, with a mean age of 11.7 years. The most common food allergens were cow's milk, egg, curry, tomato and sesame. Sesame sensitivity was found in 35 patients (14.1%. Only five patients (2% had sesame allergy. Sesame-sensitive patients had a significantly higher frequency of positive prick test to cross-reacting foods when compared to non-sensitized patients (p=0.00. The type of symptom was independent of gender and age of the patients, but urticaria and dermatitis-eczema were significantly more frequent in sensitized patients (p=0.008.Conclusions: This is the first study addressing the prevalence of sesame seed allergy in Iranian population. We found sesame to be a common and important cause of food allergy. The panel of foods recommended for use in diagnostic allergy tests should be adjusted.

    Full Text Available Lack of vaccination and modern health care facilities in many countries including Iran let meningococcemia to remain as a serious challenging disorder especially among children and in spite of improved diagnosis and earlier treatment its prognosis is still dismal. This study describes 68 cases (54.4% male of proved meningococcemia hospitalized since 1992 up to the end of 2002 in Children Medical Center Hospital, Tehran, Iran. Infants of 6 to 12 month old were a major concern in number (14.7% and severity of disease. 5.9% of the cases have had at least two hospitalization history for meningococcal septicemia and 19.1% of the patients had Systemic Lupus Erythematosus (SLE, nephrotic syndrome or chronic liver disease in their past medical history. Meningeal irritation signs were seen in 55.9% and cerebrospinal fluid (CSF smear was positive in 71.4% and culture was positive in 48.5% of patients. Meningococcal septicemia ended in shock (38.2%, Disseminated intravascular coagulation (DIC (7.4%, thrombocytopenia (10.3%, arthritis (4.4%,ocular complications (2.9%, pericarditis (2.9% and seizure (8.8% in 51 of the cases, and death occurred in 7 patients. This study shows that the manifestation of the disease is similar to those described elsewhere except for lower pneumonia and no seasonal variations.

    Full Text Available Objectives: To analyze the frequency of βS-globin haplotypes and alpha-thalassemia, and their influence on clinical manifestations and the hematological profile of children with sickle cell anemia. Method: The frequency of βS-globin haplotypes and alpha-thalassemia and any association with clinical and laboratorial manifestations were determined in 117 sickle cell anemia children aged 3–71 months. The confirmation of hemoglobin SS and determination of the haplotypes were achieved by polymerase chain reaction-restriction fragment length polymorphism, and alpha-thalassemia genotyping was by multiplex polymerase chain reaction (single-tube multiplex-polymerase chain reaction. Results: The genotype distribution of haplotypes was 43 (36.7% Central African Republic/Benin, 41 (35.0% Central African Republic/Central African Republic, 20 (17.0% Rare/atypical, and 13 (11.1% Benin/Benin. The frequency of the α3.7 deletion was 1.71% as homozygous (−α3.7/−α3.7 and 11.9% as heterozygous (−α3.7/αα. The only significant association in respect to haplotypes was related to the mean corpuscular volume. The presence of alpha-thalassemia was significantly associated to decreases in mean corpuscular volume, mean corpuscular hemoglobin and reticulocyte count and to an increase in the red blood cell count. There were no significant associations of βS-globin haplotypes and alpha-thalassemia with clinical manifestations. Conclusions: In the study population, the frequency of alpha-thalassemia was similar to published data in Brazil with the Central African Republic haplotype being the most common, followed by the Benin haplotype. βS-globin haplotypes and interaction between alpha-thalassemia and sickle cell anemia did not influence fetal hemoglobin concentrations or the number of clinical manifestations.

    Full Text Available Introduction: Clinical manifestations of primary hyper-para-thyroidism (pHPT had been dramatically changed during last 25 years. Evaluation of changes in clinical findings was the aim of this study. Materials and methods: In a retrospective, descriptive case series, patients' records of all 47 pHPT (44 females, 3 males from 1988 till 1998 were studied. Patients’ clinical presentations, signs and symptoms, laboratory and radiologic findings were reviewed and the results were compared with 34 patients' studied during 1978-1987. Serum Ca>10.5 mg/dl with increased or high normal PTH were the diagnostic criteria of pHPT. Results: Patients’ age range was 11-70 and mean ±SD was 38±16 years, with a female to male ratio of 14:1. 57 percent of the patients had bone pain and muscle weakness, 12 percent were asymptomatic, 10 percent had pathologic fractures, 8 percent had renal stones, 8 percent had symptoms of hypercalcemia, and 2 percent had giant cell lesion. The mean±SD of serum calcium was 11.48±1.16 mg/dl, phosphorus was 2.4±0.6 mg/dl and 24-h urinary Ca was 294±197 mg. Serum PTH was increased from 1.5 to 500 folds. The frequency of single adenoma in right inferior, left inferior, and left superior gland were 43 percent, 30 percent, and 13 percent respectively. Conclusion: In the study 12 percent of patients were asymptomatic whereas there was no asymptomatic case in the previous study. Prevalence of severe bone disease and the interval between onset of symptoms and diagnosis was also reduced. According to this study detection of pHPT in asymptomatic phase remarkably increased.

    Full Text Available BACKGROUND: A better description of the clinical and laboratory manifestations of fatal patients with dengue hemorrhagic fever (DHF is important in alerting clinicians of severe dengue and improving management. METHODS AND FINDINGS: Of 309 adults with DHF, 10 fatal patients and 299 survivors (controls were retrospectively analyzed. Regarding causes of fatality, massive gastrointestinal (GI bleeding was found in 4 patients, dengue shock syndrome (DSS alone in 2; DSS/subarachnoid hemorrhage, Klebsiella pneumoniae meningitis/bacteremia, ventilator associated pneumonia, and massive GI bleeding/Enterococcus faecalis bacteremia each in one. Fatal patients were found to have significantly higher frequencies of early altered consciousness (≤24 h after hospitalization, hypothermia, GI bleeding/massive GI bleeding, DSS, concurrent bacteremia with/without shock, pulmonary edema, renal/hepatic failure, and subarachnoid hemorrhage. Among those experienced early altered consciousness, massive GI bleeding alone/with uremia/with E. faecalis bacteremia, and K. pneumoniae meningitis/bacteremia were each found in one patient. Significantly higher proportion of bandemia from initial (arrival laboratory data in fatal patients as compared to controls, and higher proportion of pre-fatal leukocytosis and lower pre-fatal platelet count as compared to initial laboratory data of fatal patients were found. Massive GI bleeding (33.3% and bacteremia (25% were the major causes of pre-fatal leukocytosis in the deceased patients; 33.3% of the patients with pre-fatal profound thrombocytopenia (<20,000/µL, and 50% of the patients with pre-fatal prothrombin time (PT prolongation experienced massive GI bleeding. CONCLUSIONS: Our report highlights causes of fatality other than DSS in patients with severe dengue, and suggested hypothermia, leukocytosis and bandemia may be warning signs of severe dengue. Clinicians should be alert to the potential development of massive GI bleeding

    The hypereosinophilic syndrome (HES) commonly involves liver and spleen but only a few literature has reported the imaging features. In this article, we present the imaging features of the liver and spleen in HES patients together with clinical and laboratory features. This study included 5 HES patients with hepatic involvement. Extensive laboratory tests including multiple hematologic, serologic, parasitological, and immunologic examinations were performed. Imaging studies included CT, ultrasound (US)of upper abdomen and hepatosplenic scintigraphy. All patients were periodically examined by laboratory and imaging studies for 4 to 24 months. The common clinical presentations were weakness, mild fever, and dry cough. All patients revealed leukocytosis with eosinophilia of 40 to 80% and benign eosinophilic hyperplasia of the bone marrow. The percutaneous biopsy of the hepatic focal lesions performed in 2 patients showed numerous benigin eosinophilic infiltrates and one of them revealed combined calibration necrosis of hepatocytes. All cases revealed hepatomegaly with multiple focal lesions on at least on of CT, US, or scintigraphy. These findings completely disappeared in 2 to 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphic studies showed hepatic multifocal lesions with hepatomegaly. Differential diagnosis of these findings should include metastatic disease, lymphoma, leukemia, candidiasis or other opportunistic infections.

In this article, symptoms, extraintestinal manifestations and coexistence with other autoimmune disorders of adult patients with celiac disease were evaluated. Material and Method: 22 patients whose followed with the diagnosis of celiac disease in Suleyman Demirel University Department of Gastroenterology, between January 2007 and Semptember 2010, were evaluated retrospectively. Symptoms, extraintestinal manifestations and coexistence with other autoimmune disorders of patients at presentation were investigated. Results: 13 (59% of all cases were female and 9 (41% were male. Mean age at presentation was 38,5 years. Most common complaints were diarrhea and weakness . Tissue transglutaminase and/or antiendomysium antibody were positive, and diagnosis was confirmed by histopathologic examination in all patients. Iron deficiency, vitamine B12 deficiency and folic acid deficiency were detected in 17 (77%, 8 (36% and 6 (27% patients, respectively. There were elevated transaminase levels in 8 (36% patients. Osteoporosis was detected in 4 female and 1 male patients. Sensorimotor polineuropathy was detected in 2 patients. There was growth retardation in 2 patients. Autoimmune hypothyroidism and Type 1 diabetes mellitus were detected in 2 and 1 patients, respectively. Coexistence with Crohn%u2019s disease was detected in a patient. Discussion: Celiac disease may present with extraintestinal manifestations in adults. It should be remembered, especially in patients with iron deficiency and mild to moderate transaminase elevations with unexplained etiology. It should be considered in patients with chronic diarrhea and

    Full Text Available Leptospirosis has protean clinical manifestations. The classical presentation of the disease is an acute biphasic febrile illness with or without jaundice. Unusual clinical manifestations may result from involvement of pulmonary, cardiovascular, neural, gastrointestinal, ocular and other systems. Immunological phenomena secondary to antigenic mimicry may also be an important component of many clinical features and may be responsible for reactive arthritis. Leptospirosis in early pregnancy may lead to fetal loss. There are a few reports of leptospirosis in HIV- infected individuals but no generalisation can be made due to paucity of data. It is important to bear in mind that leptospiral illness may be a significant component in cases of dual infections or in simultaneous infections with more than two pathogens.

  11. Clinical manifestation of myeloperoxidase deficiency.

    Lanza, F

    1998-09-01

    Myeloperoxidase (MPO), an iron-containing heme protein localized in the azurophilic granules of neutrophil granulocytes and in the lysosomes of monocytes, is involved in the killing of several micro-organisms and foreign cells, including bacteria, fungi, viruses, red cells, and malignant and nonmalignant nucleated cells. Despite the primary role of the oxygen-dependent MPO system in the destruction of certain phagocytosed microbes, subjects with total or partial MPO deficiency generally do not have an increased frequency of infections, probably because other MPO-independent mechanism(s) for microbicidal activity compensate for the lack of MPO. Infectious diseases, especially with species of Candida, have been observed predominantly in MPO-deficient patients who also have diabetes mellitus, but the frequency of such cases is very low, less than 5% of reported MPO-deficient subjects. Evidence from a number of investigators indicates that individuals with total MPO deficiency show a high incidence of malignant tumors. Since MPO-deficient PMNs exhibit in vitro a depressed lytic action against malignant human cells, it can be speculated that the neutrophil MPO system plays a central role in the tumor surveillance of the host. However, any definitive conclusion on the association between MPO deficiency and the occurrence of cancers needs to be confirmed in further clinical studies. Clinical manifestations of this disorder depend on the nature of the defect; an acquired abnormality associated with other hematological or nonhematological diseases has been occasionally described, but the primary deficiency is the form more commonly reported. Another area of interest pertinent to MPO expression is related to the use of anti-MPO monoclonal antibodies for the lineage assignment of acute leukemic cells, the definition of FAB MO acute myeloid leukemia, the identification of biphenotypic acute leukemias, and their distinction from acute leukemia with minimal phenotypic deviation

    Obstructive sleep apnea (OSA) may manifest in a number of ways from subtle intrusion into daily life to profound sleepiness, snoring, witnessed apneas and other classic symptoms. Although there is increasing evidence suggesting OSA can adversely affect health in a variety of ways, this disorder remains underdiagnosed. The most well-escribed health consequences of OSA relate to the cardiovascular system. Hypertension and arrhythmias have a strong association with OSA, and evidence suggests that treatment of OSA in patients with refractory hypertension and in patients planning cardioversion for atrial fibrillation may be of particularly importance. Significant associations between heart failure and OSA as well as complex sleep apnea have also been well-described. Cerebrovascular insult, impaired neurocognition, and poorly controlled mood disorder are also associated with in OSA. Therapy for OSA may ameliorate atherosclerotic progression and improve outcomes post-cerebrovascular accident (CVA). OSA should be considered in patients complaining of poor concentration at work, actual or near-miss motor vehicle accidents, and patients with severe sleepiness as a component of their co-morbid mood disorders. The metabolic impact of OSA has also been studied, particularly in relation to glucose homeostasis. Also of interest is the potential impact OSA has on lipid metabolism. The adverse effect untreated OSA has on glucose tolerance and lipid levels has led to the suggestion that OSA is yet another constituent of the metabolic syndrome. Some of these metabolic derangements may be related to the adverse effects untreated OSA has on hepatic health. The cardiovascular, neurocognitive, and metabolic manifestations of OSA can have a significant impact on patient health and quality of life. In many instances, evidence exists that therapy not only improves outcomes in general, but also modifies the severity of co-morbid disease. To mitigate the long-term sequela of this disease

    Full Text Available Organizing pneumonia is a clinical entity asociated with nonspecific symptoms and radiological findings and abnormalities in pulmonary function tests. It is defined by the characteristic histopathological pattern: filling of alveoli and respiratory bronchioles by plugs of granulation tissue. It can be idiopathic (COP or secondary to other causes (SOP. It is an unusual finding and the clinical and radiographic findings are nonspecific. For specific diagnosis an invasive procedure has to be done, but often empirical treatment is started when there's a clinical suspicion. We describe the clinical characteristics of 13 patients with histological diagnosis of organizing pneumonia. Data was obtained from their medical records. The median age was 76 years and the median time to diagnosis from the onset of symptoms was 31 days. In 10 cases the diagnosis was made by transbronchial biopsy. 8 patients required hospitalization, 4 of them received high doses of steroids and 3 required ventilatory support. One patient died from a cause attributable to this entity and 5 relapsed. Dyspnea, cough and fever were the most frequent symptoms. Most patients had more than one tomographic pattern being the most common ground glass opacities and alveolar consolidation. Nine patients were diagnosed with COP and 4 with SOP. The most frequent underlying cause of SOP was drug toxicity. The clinical characteristics of the reported cases are consistent with previously published series. As an interesting feature, there was a group of patients that needed high doses of steroids and ventilatory support.

    The diagnosis of animals infected with BLV can be accurately identified with the available serologic tests. Diagnosis of animals in the incipient stage of leukosis is extremely difficult and can only be diagnosed by a positive tissue biopsy. Animals with frank tumor involvement can be suspected and diagnosed on a tentative clinical basis on the signs reported. Positive diagnosis must be made on the basis of a biopsy of the tumor or in some cases on a hemotological examination.

    Cellulitis is an acute bacterial non-necrotizing dermal-hypodermal infection predominantly affecting the lower limbs. It is characterised by a circumscribed erythema with a raised border and fever. The predisposing factors are skin wounds, edema from any cause and systemic factors (diabetes, immunosuppression). The diagnosis is clinical and the most common complication is recurrence. Other complications include local abscess, fasciitis and bacteremia. The germ is rarely identified. The majority of infections (85%) is due to group A beta-hemolytic streptococcus. The treatment of cellulitis consists of an association of an antibiotic with rest of the concerned area.

    1990-01-01

    Chloracne is a rare but important acneiform eruption often associated with the ingestion of chlorinated phenolic agents such as dioxins with subsequent toxicity from these chemicals. Clinically, chloracne can be distinguished from acne vulgaris by the distribution and appearance of the lesions and by taking a detailed history. In some instances, it may be associated with particularly xerotic skin, pigmentation, follicular hyperkeratosis, conjunctivitis, and actinic elastosis. Histologically, the primary lesion is a follicular plug containing keratinous material. Chloracne is difficult if not impossible to treat adequately and once present, may persist for years. Consequently, good hygiene, safe manufacturing processes so that no inhalation or skin contact is possible, and the elimination of atmospheric contamination are all necessary in the prevention of this potentially debilitating disease.34 references.

    Lyme disease (Lyme borreliosis) is a systemic infectious disease that can present in a variety of clinical manifestations. The disease is caused by a group of spirochaetes--Borrelia burgdorferi sensu lato or Lyme borrelia--that are transmitted to humans by the bite of Ixodes ticks. Lyme disease is the most common arthropode-borne infectious disease in many European countries including Germany. Early localized infection is typically manifested by an erythema migrans skin lesion, in rarer cases as a borrelial lymphocytoma. The most common early disseminated manifestation is (early) neuroborreliosis. In adults, neuroborreliosis appears typically as meningoradiculoneuritis. Neuroborreliosis in children, however, is typically manifested by meningitis. In addition, multiple erythema migrans lesions and Lyme carditis occur relatively frequently. The most common manifestation oflate Lyme disease is Lyme arthritis. Early manifestations (and usually also late manifestations) of Lyme disease can be treated successfully by application of suitable antibacterial agents. For the treatment of Lyme disease, doxycycline, certain penicillins such as amoxicillin and some cephalosporins (ceftriaxone, cefotaxime, cefuroxime axetil) are recommended in current guidelines. A major challenge is the treatment of chronic, non-specific disorders, i. e., posttreatment Lyme disease syndrome and "chronic Lyme disease". Prevention of Lyme disease is mainly accomplished by protecting against tick bites. Prophylactic administration of doxycycline after tick bites is generally not recommended in Germany. There is no vaccine available for human beings.

    Full Text Available Currently, substance abuse is one of the most serious problems facing our society. The aim of this study was to investigate the clinical manifestations of the opiate withdrawal syndrome (OWS. The study included 112 patients (57 women and 55 men aged from 18 to 64 years with opium addiction according to the DSM-IV. To study the clinical manifestation of OWS, the special 25-score scale with four sections to assess severity of sleep disorders, pain syndrome, autonomic disorders, and affective symptoms was used. Given the diversity of the OWS symptoms, attention was focused on three clinical variants, affective, algic and mixed. The OWS affective variant was registered more frequently in women, while the mixed type of OWS was more typical of men.

    Due to improved living conditions and subsequent changes in hepatitis A epidemiology, the disease burden of hepatitis A is increasing in many regions. Recently, Korea has faced a large, community-wide outbreak of hepatitis A, which has prompted a vaccination program. The clinical spectrum of hepatitis A virus infection ranges from asymptomatic infection to fulminant hepatitis. Clinical manifestations depend on the age of the host: less than 30% of infected young children are symptomatic, while about 80% of infected adults manifest severe hepatitis with remarkably elevated serum aminotransferases. Fulminant hepatitis is rare, with a reported incidence from 0.015 to 0.5%. Atypical manifestations include relapsing hepatitis and prolonged cholestasis, and complicated cases with acute kidney injury have been reported. Extrahepatic manifestations, such as autoimmune hemolytic anemia, aplastic anemia, pure red cell aplasia, pleural or pericardial effusion, acute reactive arthritis, acute pancreatitis, acalculous cholecystitis, mononeuritis, and Guillain-Barré syndrome, have been rarely reported. Management of hepatitis A includes general supportive care, and critical decisions regarding liver transplantation await further studies on prognostic predictors. Fundamental management of hepatitis A is active vaccination. However, a vaccination program should be adapted to the regional situation, according to differing epidemiology and disease burden.

    Full Text Available Acromegaly and gigantism are due to excess GH production, usually as a result of a pituitary adenoma. The incidence of acromegaly is 5 cases per million per year and the prevalence is 60 cases per million. Clinical manifestations in each patient depend on the levels of GH and IGF-I, age, tumor size, and the delay in diagnosis. Manifestations of acromegaly are varied and include acral and soft tissue overgrowth, joint pain, diabetes mellitus, hypertension, and heart and respiratory failure. Acromegaly is a disabling disease that is associated with increased morbidity and reduced life expectancy. The diagnosis is based primarily on clinical features and confirmed by measuring GH levels after oral glucose loading and the estimation of IGF-I. It has been suggested that the rate of mortality in patients with acromegaly is correlated with the degree of control of GH. Adequately treated, the relative mortality risk can be markedly reduced towards normal.

    Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disease, caused by genetic deficiency of the 27-hydroxylase enzyme (encoded by CYP27A1). It plays a key role in cholesterol metabolism, especially in bile acid synthesis and in the 25-hydroxylation of vitamin D3 in the liver. Its deficiency causes reduced bile acid synthesis and tissue accumulation of cholestanol. Clinical manifestations are related to the presence of cholestanol deposits and include tendon xanthomas, premature cataracts, chronic diarrhea, progressive neurologic impairment and less frequently coronary heart disease, early onset osteoporosis and abnormalities in the optic disk and retina. An early diagnosis and treatment with quenodeoxycholic acid may prevent further complications, mainly neurological manifestations. This review summarizes cholesterol metabolism related to bile acid synthesis, physiopathology, biochemistry and treatment of cerebrotendinous xanthomatosis.

    Neurocysticercosis (NCC) is the most frequent parasitic disease of the human brain. Modern imaging studies, CT and MRI, have defined the diagnosis and characterization of the disease. Through these studies the therapeutic approach for each case may be individualized with the aid of antihelmintics, steroids, symptomatic medicines, or surgery. The use of one or various therapeutic measures largely depends on the peculiar combination of number, location, and biological stage of lesions as well as the degree of inflammatory response to the parasites. Although there is not a typical clinical picture of NCC, epilepsy is the most frequent manifestation of parenchymal NCC, whereas hydrocephalus is the most frequent manifestation of meningeal NCC. Eradication of cysticercosis is an attainable goal by public education and sanitary improvement in endemic areas.

    2015-02-01

    Hereditary angioedema is a genetic disorder typically related to insufficient or dysfunctional C1-esterase inhibitor. Patients present with episodic swelling of various body parts, such as the face, neck, bowel, genitals, and extremities. Acute or severe symptoms can lead to patients presenting to the emergency room, particularly when the neck and abdominopelvic regions are affected, which is often accompanied by radiologic imaging evaluation. Patients with hereditary angioedema can pose a diagnostic challenge for emergency department physicians and radiologists at initial presentation, and the correct diagnosis may be missed or delayed, due to lack of clinical awareness of the disease or lack of its consideration in the radiologic differential diagnosis. Timely diagnosis of hereditary angioedema and rapid initiation of appropriate therapy can avoid potentially life-threatening complications. This article focuses on the spectrum of common and characteristic acute imaging manifestations of hereditary angioedema and provides an update on important recent developments in its clinical management and treatment.

    2012-06-01

    Sarcoidosis is an idiopathic granulomatous disease affecting multiple organs. Neurosarcoidosis, involving the central and/or peripheral nervous systems, is a relatively rare form of sarcoidosis. Its clinical manifestations include cranial neuropathies, meningitis, neuroendocrinological dysfunction, hydrocephalus, seizures, neuropsychiatric symptoms, myelopathy and neuropathies. The diagnosis is problematic, especially when occurring as an isolated form without other organ involvement. Distinguishing neurosarcoidosis from other granulomatous diseases and multiple sclerosis is especially important. Although biopsy of neural tissue is the gold standard for the diagnosis of neurosarcoidosis, this is often not practical and the diagnosis must be inferred though other tests, often coupled with biopsy of extraneural organs. Corticosteroids and other immuno-suppressants are frequently used for the treatment of neurosarcoidosis. This article reviews the epidemiology, pathogenesis, pathology, clinical features, diagnosis, diagnostic tests, diagnostic criteria, and therapy of neurosarcoidosis.

    Hypertonicity causes severe clinical manifestations and is associated with mortality and severe short-term and long-term neurological sequelae. The main clinical syndromes of hypertonicity are hypernatremia and hyperglycemia. Hypernatremia results from relative excess of body sodium over body water. Loss of water in excess of intake, gain of sodium salts in excess of losses or a combination of the two are the main mechanisms of hypernatremia. Hypernatremia can be hypervolemic, euvolemic or hypovolemic. The management of hypernatremia addresses both a quantitative replacement of water and, if present, sodium deficit, and correction of the underlying pathophysiologic process that led to hypernatremia. Hypertonicity in hyperglycemia has two components, solute gain secondary to glucose accumulation in the extracellular compartment and water loss through hyperglycemic osmotic diuresis in excess of the losses of sodium and potassium. Differentiating between these two components of hypertonicity has major therapeutic implications because the first component will be reversed simply by normalization of serum glucose concentration while the second component will require hypotonic fluid replacement. An estimate of the magnitude of the relative water deficit secondary to osmotic diuresis is obtained by the corrected sodium concentration, which represents a calculated value of the serum sodium concentration that would result from reduction of the serum glucose concentration to a normal level.

    Full Text Available Calcium pyrophosphate deposition (CPPD disease is an arthropathy caused by calcium pyrophosphate dihydrate (CPP crystal deposits in articular tissues, most commonly fibrocartilage and hyaline cartilage. According to EULAR, four different clinical presentations can be observed: 1 asymptomatic CPPD; 2 osteoarthritis (OA with CPPD; 3 acute CPP crystal arthritis; 4 chronic CPP inflammatory crystal arthritis. Acute CPP crystal arthritis is characterized by sudden onset of pain, swelling and tenderness with overlying erythema, usually in a large joint, most often the knee, wrist, shoulder, and hip. Occasionally, ligaments, tendons, bursae, bone and the spine can be involved. CPPD of the atlanto-occipital joint (crowned dens syndrome can cause periodic acute cervico-occipital pain with fever, neck stiffness and laboratory inflammatory syndrome. Chronic inflammatory arthritis is characterized by joint swelling, morning stiffness, pain, and high ESR and CRP. The relationship between OA and CPPD is still unclear. The main problem is whether such crystals are directly involved in the pathogenesis of OA or if they are the result of joint degeneration. Diagnosis is based on evaluation of history and clinical features, conventional radiology, and synovial fluid examination. Non-polarized light microscopy should be used initially to screen for CPPD crystals based upon their characteristic morphology, and compensated polarized light microscopy, showing the crystals to be weakly positive birefringent, is recommended for definitive identification, although this last pattern only occurs in about 20% of samples. The main goals of CPPD therapy are control of the acute or chronic inflammatory reaction and prevention of further episodes.

    AIM: To analyze systematically our experience over 22 years with symptomatic acquired diverticular disease of the jejunum and ileum, exploring the clinical manifestations and diagnosis of this rare but life-threatening disease.METHODS: The medical records of patients with surgically confirmed symptomatic jejunoileal diverticular disease were retrospectively reviewed. Data collected included demographic data, laboratory results, clinical course (acute or chronic), preoperative diagnosis, and operative findings. Inclusion criteria were as follows: (1) surgical confirmation of jejunoileal diverticular disease and (2)exclusion of congenital diverticula (e.g. Meckel's diverticulum).RESULTS: From January 1982 to July 2004, 28 patients with a total of 29 operations met the study criteria. The male:female ratio was 14:14, and the mean age was 62.6±3.5 years. The most common manifestation was abdominal pain. In nearly half of the patients, the symptoms were chronic. Two patients died after surgery. Only four cases were correctly diagnosed prior to surgery, three by small bowel series.CONCLUSION: Symptomatic acquired small bowel diverticular disease is difficult to diagnose. It should be considered in older patients with unexplained chronic abdominal symptoms. A small bowel series may be helpful in diagnosing this potentially life-threatening disease.

    2014-09-01

    Uterine fibroids (leiomyomata) are extremely common lesions that are associated with detrimental effects including infertility and abnormal uterine bleeding. Fibroids cause molecular changes at the level of endometrium. Abnormal regulation of growth factors and cytokines in fibroid cells may contribute to negative endometrial effects. Understanding of fibroid biology has greatly increased over the last decade. Although the current armamentarium of Food and Drug Administration-approved medical therapies is limited, there are medications approved for use in heavy menstrual bleeding that can be used for the medical management of fibroids. Emergence of the role of growth factors in pathophysiology of fibroids has led researchers to develop novel therapeutics. Despite advances in medical therapies, surgical management remains a mainstay of fibroid treatment. Destruction of fibroids by interventional radiological procedures provides other effective treatments. Further experimental studies and clinical trials are required to determine which therapies will provide the greatest benefits to patients with fibroids.

    Full Text Available Background: The phylum Cnidarians have over nine thousand species that approximately, one hundred species are dangerous for humans. Annually, a large number of deaths were reported due to jellyfish stings. The manifestations depend on their species and kind of venoms, and include the local and systemic manifestations. A number of methods and compounds were used and under investigation for management of injuries with jellyfishes. Due to the lack of an integrated systematic review, the current study was done. Materials and Methods: The PubMed data bank was searched for the term “Jellyfish”. A total of 1677 papers were found. These papers were divided into three categories: medical, biomedical and biotechnological fields. The medical category was further divided into three subcategories comprising systemic manifestations, cutaneous manifestations and treatments for the stings of jellyfishes. The biomedical category was further subdivided into genomics, proteomics, and biology of venoms, mechanisms of actions and products of biomedical significance. In this part of systematic review, the medical aspects of injuries with jellyfishes were evaluated. Results: The clinical manifestations in jellyfish envenomation depend on their species and the nature of venoms. The most common clinical manifestations of jellyfish stings are cutaneous presentations like urticasia, erythema, swelling, vesicles and severe dermonectoric manifestations. Systemic manifestations were seen in the stings of box jellyfishes, Portuguese man-of-war and in Irukandji syndrome. The most common recommendations for jellyfish envenomation managements include decreasing the local effects of venom, prevention of the venomous nematocysts release, and Controlling of systemic reactions. Application of commercial vinegar (4 - 6% acetic acid, hot water immersion (HWI (42 ° C for 20 minutes, ice packs, sea water rinsing for inactivating nematocysts, administration of topical and parenteral

These diseases have more adverse effects and more importance in children. This study was aimed at determining the prevalence of intestinal parasites and their clinical manifestations in children 0-14 years old referred to Yazd Central Laboratory. Methods: The present cross- sectional descriptive study was performed during the April 2005 to September 2006, with data obtained from the stool samples of 1500 children, using both wet mount smear (physiologic saline and Lugol΄s solutions and formalin-ethyl acetate concentration method for detection of the intestinal parasites and also with the tape test for eggs of Enterobius vermicularis and Taenia. Results: From 1500 examined stool samples, 128(8.5% cases were positive for one of the intestinal parasites, including 67(52.3% females and 61(47.7% males. Ninety five percent of positive cases were infected with protozoa and 5% with helminths. The most frequent protozoans were Blastocystis hominis 41.3%, Giardia lamblia 33.6%, and Entamoeba coli 14.7%. Enterobius vermicularis (4.3% and Hymenolepis nana (0.7% were the helminth species. The most abundant infection rate was shown in the 5-9 years old group, with a significant difference compared with other age groups (P< 0.05. About 87% of children infested with Blastocystis hominis showed more than 5 Blastocystis per 400x microscope fields, and 100% of children infested with Giardia lamblia and Chilomastix mesnili had clinical symptoms. Conclusion: In this study, lower contamination rates in comparison with the similar studies conducted in other regions of the country was seen, which may be as a result of the hot and dry climate and improved personal hygiene and public health services. There is a need for further studies about the prevalence and clinical symptoms of

    Full Text Available Since the emergence of West Nile virus (WNV in North America in 1999, understanding of the clinical features, spectrum of illness and eventual functional outcomes of human illness has increased tremendously. Most human infections with WNV remain clinically silent. Among those persons developing symptomatic illness, most develop a self-limited febrile illness. More severe illness with WNV (West Nile neuroinvasive disease, WNND is manifested as meningitis, encephalitis or an acute anterior (polio myelitis. These manifestations are generally more prevalent in older persons or those with immunosuppression. In the future, a more thorough understanding of the long-term physical, cognitive and functional outcomes of persons recovering from WNV illness will be important in understanding the overall illness burden.

In the study group of 204 patients (146 male and 58 female with proven bronchogenic carcinoma, PNS was present in 18 (8.62% patients. The patients with PNS were divided into two groups. The first one consisted of 13 (72.2% patients with symptoms related to primary tumours while the second one consisted of 5 (27.7% patients with symptoms, at initial appearance, indicative of disorders of other organs and systems. The predominant disorder was Lambert-Eaton Syndrome, associated with small-cell carcinoma. Endocrine manifestations included: inappropriate antidiuretic hormone production syndrome (small-cell carcinoma, a gonadotropin effect with gynaecomastia and testicular atrophy (planocellular carcinoma, small-cell carcinoma, a case of Cushing Syndrome (small-cell carcinoma, and hyper-calcaemia, due to the production of the parathyroid hormone-related peptide, which was associated with planocellular carcinoma. A rare case of bilateral exophthalmos was found as PNS at adenocarcinoma. Digital clubbing and hypertrophic osteoarthropathy (HO were associated with planocellular and adenocarcinoma, while clubbing was much more common than HO, especially among women. The differences between the two groups were related to the time of PNS appearance. In the first group, PNS occurred late on in the illness, while in the second group, PNS preceded the diagnosis of BC. Alternatively, the disappearance of a clinical or a radiological manifestation of PNS after surgery or chemotherapy may be an indicator of an improvement in health or PNS may be the first sign of illness recurrence. Radiological manifestations of PNS in asymptomatic patients may serve as a useful screen for identifying primary BC. In symptomatic patients, it may be an

    Inflammation and coagulation are known to affect each other in many ways. Vasculitis represents a group of disorders where blood vessels (small, medium, large or variable) are infiltrated with inflammatory cells. Accumulating evidence in the literature suggests both clinical and physiological association between vasculitis and thrombosis. Vasculitis-associated thrombosis involves arteries and veins, and a tight connection has been reported between the activity of vasculitis and the appearance of thrombosis. Pathophysiology of these relations is complex and not completely understood. While thrombophilic factors are associated with vasculitis, it remains unclear whether a true association with clinical thrombosis is present. Furthermore, several factors leading to hemostasis, endothelial injury and induction of microparticles were described as possibly accounting for thrombosis. Management of thrombosis in vasculitis patients is challenging and should be further assessed in randomized controlled studies. The current review describes clinical manifestations, pathogenesis and management of thrombosis associated with different vasculitides.

    Full Text Available At the beginning of a new millennium, syphilis incidence has been increasing worldwide, occurring primarily among men who have sex with men (MSM. The clinical features of primary syphilis among MSM is described, a case-note review of the primary syphilis (PS patients who attended the Institute of Skin and Venereal Diseases. The diagnosis was assessed based upon the clinical features and positive syphilis serology tests. Among 25 patients with early syphilis referred during 2010, PS was diagnosed in a total of 13 cases. In all patients, unprotected oral sex was the only possible route of transmission, and two out of 13 patients had HIV co-infection. Overall, 77% of men presented with atypical penile manifestation. The VDRL test was positive with low titers. The numerous atypical clinical presentations of PS emphasize the importance of continuing education of non-experienced physicians, especially in countries with lower reported incidence of syphilis.

    Full Text Available The lecture provides information about the etiology and pathogenesis of antiphospholipid syndrome (APS and genetic susceptibility to its development. The most recent international diagnostic criteria for APS and its variants have been reported. This syndrome can affect multiple organ systems depending on localization of thrombosis; therefore, nowadays the problem of APS is multidisciplinary. Clinical manifestations of APS are rather general (thrombosis of different localization; thus, the diagnosis can be verified only in the case of presence of antiphospholipid antibodies. The differential diagnosis of APS is discussed.

    Full Text Available Over the past few decades, there has been an increase in the number of reports about newly recognized (atypical or unusual manifestations of Graves' disease (GD, that are related to various body systems. One of these manifestations is sometimes the main presenting feature of GD. Some of the atypical manifestations are specifically related to GD, while others are also similarly seen in patients with other forms of hyperthyroidism. Lack of knowledge of the association between these findings and GD may lead to delay in diagnosis, misdiagnosis, or unnecessary investigations. The atypical clinical presentations of GD include anemia, vomiting, jaundice, and right heart failure. There is one type of anemia that is not explained by any of the known etiological factors and responds well to hyperthyroidism treatment. This type of anemia resembles anemia of chronic disease and may be termed GD anemia. Other forms of anemia that are associated with GD include pernicious anemia, iron deficiency anemia of celiac disease, and autoimmune hemolytic anemia. Vomiting has been reported as a presenting feature of Graves' disease. Some cases had the typical findings of hyperthyroidism initially masked, and the vomiting did not improve until hyperthyroidism has been detected and treated. Hyperthyroidism may present with jaundice, and on the other hand, deep jaundice may develop with the onset of overt hyperthyroidism in previously compensated chronic liver disease patients. Pulmonary hypertension is reported to be associated with GD and to respond to its treatment. GD-related pulmonary hypertension may be so severe to produce isolated right-sided heart failure that is occasionally found as the presenting manifestation of GD.

    The nature of pathology services is changing under the combined pressures of increasing workloads, cost constraints and technological advancement. In the face of this, laboratory systems need to meet new demands for data exchange with clinical electronic record systems for test requesting and results reporting. As these needs develop, new challenges are emerging especially with respect to the format and content of the datasets which are being exchanged. If the potential for the inclusion of intelligent systems in both these areas is to be realised, the continued dialogue between clinicians and laboratory information specialists is of paramount importance. Requirements of information technology (IT) in pathology, now extend well beyond the provision of purely analytical data. With the aim of achieving seamless integration of laboratory data into the total clinical pathway, 'Informatics' - the art and science of turning data into useful information - is becoming increasingly important in laboratory medicine. Informatics is a powerful tool in pathology - whether in implementing processes for pathology modernisation, introducing new diagnostic modalities (e.g. proteomics, genomics), providing timely and evidence-based disease management, or enabling best use of limited and often costly resources. Providing appropriate information to empowered and interested patients - which requires critical assessment of the ever-increasing volume of information available - can also benefit greatly from appropriate use of informatics in enhancing self-management of long term conditions. The increasing demands placed on pathology information systems in the context of wider developmental change in healthcare delivery are explored in this review. General trends in medical informatics are reflected in current priorities for laboratory medicine, including the need for unified electronic records, computerised order entry, data security and recovery, and audit. We conclude that there is a

    Full Text Available Cutaneous leishmaniasis (CL is a rising epidemic in Pakistan. It is a major public health problem in the country especially alongside regions bordering the neighboring Afghanistan and cities that have had the maximum influx of refugees. The purpose of our paper is to highlight the diverse clinical manifestations of the disease seen along with the geographic areas affected, where the hosts are particularly susceptible. This would also be helpful in presenting the broad spectrum of the disease for training of health care workers and help in surveillance of CL in the region. The increased clinical diversity and the spectrum of phenotypic manifestations noted underscore the fact that the diagnosis of CL should be not only considered when dealing with common skin lesions, but also highly suspected by dermatologists and even primary care physicians even when encountering uncommon pathologies. Hence, we would strongly advocate that since most of these patients present to local health care centers and hospitals, primary care practitioners and even lady health workers (LHWs should be trained in identification of at least the common presentations of CL.

    2005-01-01

    Sacroiliac joint dysfunction is one of the proved causes of sacroiliac joint syndrome. We are talking about the restricted mobility of sacrum opposite to ilium the type of "reversible blockage of movement". Main characteristics of dysfunction are as follows: restricted "joint play", referred pain, normal radiological finding, normal lab results and disappearance of clinical symptoms after deblocking of articular bodies. Pain from a blocked joint can be referred to lower back, buttocks, hip, groin, thigh, calf and lower part of abdomen. Dispersion of painful regions is a consequence of a complex and variable innervation of articular capsule. Blocked position of articular bodies and protracted tension of articular capsule causes a stimulus of nociceptors by which a capsule is protected. Nociceptive activity is manifested with referred pains in innervational region of stimulated sensitive nerves. In the article, besides the clinical manifestations, there is described a diagnostics and manual therapy of dysfunction. Springing tests by means of which a passive mobility ("joint play") is being tested, are most valuable in dysfunction diagnostics. Manual therapy (mobilization/manipulation) is indicated and efficacious with the patients suffering from dysfunction.

    The mutation of myotonic dystrophy (DM) has been identified as unstable expansions of trinucleotide CTG repeat, located on chromosome 19q13-3. Although previous investigations have emphasized the strong association of the sizes of the CTG repeat with ages of onset as well as the clinical manifestations, effects of the paternal or maternal transmissions other than CTG repeats on the clinical manifestations in DM have not been evaluated in detail. To investigate how parental transmission affect the DM phenotype, we analyzed 15 cases of paternal transmission and 25 cases of maternal transmission. We have classified DM patients into 4 clinical grades. As in accordance with previous reports, there is a good correlation on sizes of the CTG repeat with their clinical features. The sizes of the CTG repeat in congenital DM patients (4.13{plus_minus}0.221 kbp) (Mean {plus_minus}SEM), who inherited mutant genes from their mothers, were not significantly larger than those of non-congenital DM patients (3.65 {plus_minus}0.36 kbp). As it has been well established that congenital DM patients are born to affected mothers, we investigated to see if there are any parental bias on the clinical manifestations in non-congenital DM. We classified each case into 4 classes depending on the size ranges of the CTG repeat (0 to 1.5 kbp, 1.5 to 3.0 kbp, 3.0 to 4.5 kbp, 4.5 kbp<). In each group of the size ranges of the CTG repeat, the distribution of cases among grades I to III were compared between paternally and maternally transmitted cases. There were statistically significant differences in the distributions of cases among grades I to III for the size ranges of 3 to 4.5 kbp expansions (p<0.01) and over 4.5 kbp expansions (p<0.05) on {chi}{sup 2} test, respectively. The results revealed that maternally transmitted cases tend to show severe phenotypes compared to paternally transmitted ones even if they have similar sizes of CTG repeat.

    2015-09-01

    Antiphospholipid syndrome (APLS) is a complex systemic disease with a wide variety of clinical manifestations. In the obstetric population, recurrent early pregnancy loss, fetal loss, and thrombosis are hallmarks of the disease. Patients with APLS have developed one or more pathogenic auto-antibodies directed against plasma and cell surface proteins. These antibodies are characterized by their affinity for anionic phospholipids. Interactions between APLS antibodies and their protein targets influence a wide variety of biological systems and signaling pathways, including monocytes, platelets, the complement system, and endothelial cells. While much research is currently directed at understanding the mechanisms involved in this autoimmune disease, the key clinical presentation is the hypercoagulable state resulting in thrombosis occurring in essentially any arterial or venous location, as well as numerous obstetrical complications. Treatment of APLS is generally directed at preventing thrombosis and poor pregnancy outcomes by ameliorating the hypercoagulable state.

    Moebius syndrome is a congenital, nonprogressive disorder clinically characterized by loss of facial expression, impaired stomatognathic system functions, incapacity to close the eyelids, and several oral impairments. The purpose of this paper was to present the clinical manifestations and the dental treatment in a 5-year, 2-month-old male Moebius syndrome patient. The child presented with facial asymmetry, difficulty performing facial mimic movements and pronouncing some letters, and compromised suction, mastication, breathing, and deglutition. An intraoral examination revealed hypofunction of the perioral muscles, cheeks and tongue, ankyloglossia, anterior open bite, and absence of carious lesions and dental anomalies. The dental treatment consisted of frenectomy and further placement of a removable orthodontic appliance with a palatal crib for correction of the anterior open bite. After 12 months of follow-up, anterior open bite decreased and speech, deglutition, and mastication improved.

    Full Text Available Abstract. Enteroviruses are widely distributed human infectious pathogens. In spite of infection a disease does not manifest in majority number of cases. However, in some infected persons the different kind of symptoms can be observed; from common cold signs up to  aseptic (serous meningitis and myocarditis. Severe enteroviral cases with lethal outcomes are rarely reported. Ability of enteroviruses to cause large outbreaks and even epidemic distribution is very significant for health care systems. Taking in account a high genetic diversity of enteroviruses it is possible appearance of new highly pathogenic strains in the future. In some countries including the Russian Federation the permanent surveillance for enteroviral infections is provided besides of WHO polio elimination program. The laboratory diagnostics of enterovirus infections is complicated by numerous of pathogen serotypes. Thus, classical virological methods should be supported by molecular-biological tools to sequence pathogen genome and to define phylogenetic relations between different enterovirus strains.

    Purpose The aim of this study was to investigate the clinical features and extraintestinal manifestations (EIMs) of Crohn disease (CD) in Korean pediatric patients. Methods The medical records of 73 children diagnosed with CD were retrospectively reviewed. Data regarding baseline demographic and clinical characteristics, including CD phenotype at diagnosis based on the Montreal classification, and clinical features and course of EIMs were investigated. Results Fifty-two (71.2%) of the patients were males. The mean age of the patients was 12.5 years. The mean follow-up period was 3.4 years. The disease location was ileal in 3 (4.1%) of the patients, colonic in 13 (17.8%), ileocolonic in 56 (76.7%). The clinical behavior was inflammatory in 62 (84.9%) of the patients, stricturing in 8 (11.0%), and penetrating in 3 (4.1%). Perianal abscesses or fistulas were found in 37 (50.7%) of the patients. EIMs observed during the study period were anal skin tag in 25 patients (34.2%), hypertransaminasemia in 20 (27.4%), peripheral arthritis in 2 (2.7%), erythema nodosum in 2 (2.7%), vulvitis in 1 (1.4%), uveitis in 1 (1.4%), and pulmonary thromboembolism in 1 (1.4%). Conclusion Perianal diseases and manifestations were present in more than half of Korean pediatric CD patients at diagnosis. Inspection of the anus should be mandatory in Korean children with suspicious CD, as perianal fistulas, abscesses, and anal skin tags may be the first clue to the diagnosis of CD. PMID:28090468

    Full Text Available The paper describes two patients (a 50-year woman and a 72-year man in whom the clinical manifestations of ulceronecrotic vasculitis had long preceded before the diagnosis of multiple myeloma was made. In the former, monoclonal cryoglobulinemia type I induced ulcerative lesions with the development of dry toe gangrene and paraproteinemic renal lesion. In the latter, ulceronecrotic vasculitis with the development of dry toe gangrene was a manifestation of monoclonal paraproteinemia without signs of cryoglobulinemia. Both patients were found to have monoclonal blood secretion (РIgGλ и РIgGκ and urine Bence Jones protein (BJλ+BJκ, BJκ in the absence of immunological markers of vasculitis developing in patients with rheumatic diseases. Immunochemical study of serum/urine and, when monoclonal secretion of PIg+BJ is detected, further examination for plasma cell dyscrasia should be performed in all cases of vascular disorders (cold allergy, Raynaud's syndrome, purpura, ulcers of cruses, and gangrene of distal phalanxes of the hands/feet in patients with atypical vasculitis. The timely immunochemical study of blood and urine will make it possible to diagnose plasma cell dyscrasia (different types of myelomic disease, Waldenstrцm macroglobulinemia, primary amyloidosis at the early stage of the disease and to rule out unjustifiably diagnosed vasculitis in patients with atypical vascular lesions.

    Full Text Available Psoriasis is a chronic inflammatory skin disease, which is associated with systemic inflammation and comorbidities, such as psoriatic arthritis and cardiovascular diseases. The autoimmune nature of psoriasis has been established only recently, conferring a central role to epidermal CD8 T cells recognizing self-epitopes in the initial phase of the disease. Different subsets of helper cells have also been reported as key players in the psoriasis pathogenesis. Here, we reviewed the knowledge on the role of each subset in the psoriatic cascade and in the different clinical manifestations of the disease. We will discuss the role of Th1 and Th17 cells in the initiation and in the amplification phase of cutaneous inflammation. Moreover, we will discuss the recently proposed role of tissue resident Th22 cells in disease memory in sites of recurrent psoriasis and the possible involvement of Th9 cells. Finally, we will discuss the hypothesis of a link between T helper cell subsets recirculating from the skin and the systemic manifestations of psoriasis.

    2008-01-01

    Full Text Available Cerebral venous thrombosis (CVT has a wide spectrum of clinical manifestations that may mimic many other neurological disorders and lead to misdiagnoses. Headache is the most common symptom and may be associated with other symptoms or remain isolated. The other frequent manifestations are focal neurological deficits and diffuse encephalopathies with seizures. The key to the diagnosis is the imaging of the occluded vessel or of the intravascular thrombus, by a combination of magnetic resonance imaging (MRI and magnetic resonance venography (MRV. Causes and risk factors include medical, surgical and obstetrical causes of deep vein thrombosis, genetic and acquired prothrombotic disorders, cancer and hematological disorders, inflammatory systemic disorders, pregnancy and puerperium, infections and local causes such as tumors, arteriovenous malformations, trauma, central nervous system infections and local infections. The breakdown of causes differs in different parts of the world. A meta-analysis of the most recent prospectively collected series showed an overall 15% case-fatality or dependency rate. Heparin therapy is the standard therapy at the acute stage, followed by 3-6 months of oral anticoagulation. Patients with isolated intracranial hypertension may require a lumbar puncture to remove cerebrospinal fluid before starting heparin when they develop a papilloedema that may threaten the visual acuity or decompressive hemicraniectomy. Patients who develop seizures should receive antiepileptic drugs. Cerebral venous thrombosis - even pregnancy-related - should not contraindicate future pregnancies. The efficacy and safety of local thrombolysis and decompressive hemicraniectomy should be tested

    Obesity is a risk factor for heart failure (HF) in both men and women. The mortality risk of overweight and class I and II obese adults with HF is lower than that of normal weight or underweight adults with HF of comparable severity, a phenomenon referred to as the obesity paradox. Severe obesity produces hemodynamic alterations that predispose to changes in cardiac morphology and ventricular function, which may lead to the development of HF. The presence of systemic hypertension, sleep apnea, and hypoventilation, comorbidities that occur commonly with severe obesity, may contribute to HF in such patients. The resultant syndrome is known as obesity cardiomyopathy. Substantial weight loss in severely obese persons is capable of reversing most obesity-related abnormalities of cardiac performance and morphology and improving the clinical manifestations of obesity cardiomyopathy.

    2010-01-01

    Full Text Available Over the last 4 years, three genetic etiologies of hyper IgE syndromes have been identified: STAT3, DOCK8, and Tyk2. All of these hyper IgE syndromes are characterized by eczema, sinopulmonary infections, and greatly elevated serum IgE. However, each has distinct clinical manifestations. Mutations in STAT3 cause autosomal dominant HIES (Job’s syndrome, which is unique in its diversity of connective tissue, skeletal, and vascular abnormalities. DOCK8 deficiency is characterized by severe cutaneous viral infections such as warts, and a predisposition to malignancies at a young age. Only one individual has been identified with a hyper IgE phenotype associated with Tyk2 deficiency, which is characterized by nontuberculous mycobacterial infection. The identification of these genetic etiologies is leading to advances in understanding the pathogenesis of these syndromes with the goal of improving treatment.

    Hahn, Youn-Soo; Kim, Joong-Gon

    2010-11-01

    Juvenile rheumatoid arthritis (JRA) is the most common rheumatic childhood disease; its onset is before 16 years of age and it persists for at least 6 weeks. JRA encompasses a heterogeneous group of diseases that is classified according to 3 major presentations: oligoarthritis, polyarthritis, and systemic onset diseases. These presentations may originate from the same or different causes that involve interaction with specific immunogenetic predispositions, and result in heterogeneous clinical manifestations. An arthritic joint exhibits cardinal signs of joint inflammation, such as swelling, pain, heat, and loss of function; any joint can be arthritic, but large joints are more frequently affected. Extra-articular manifestations include high fever, skin rash, serositis, and uveitis. The first 2 types of JRA are regarded as T helper 1 (Th1) cell-mediated inflammatory disorders, mainly based on the abundance of activated Th1 cells in the inflamed synovium and the pathogenetic role of proinflammatory cytokines that are mainly produced by Th1 cell-stimulated monocytes. In contrast, the pathogenesis of systemic onset disease differs from that of other types of JRA in several respects, including the lack of association with human leukocyte antigen type and the absence of autoantibodies or autoreactive T cells. Although the precise mechanism that leads to JRA remains unclear, proinflammatory cytokines are thought to be responsible for at least part of the clinical symptoms in all JRA types. The effectiveness of biologic therapy in blocking the action of these cytokines in JRA patients provides strong evidence that they play a fundamental role in JRA inflammation.

    2004-01-01

    Full Text Available Introduction Neuropathic pain in cancer patients requires a focused clinical evaluation based on knowledge of common neuropathic pain syndromes. Definition Neuropathic pain is a non-nociceptive pain or "differentiation" pain, which suggests abnormal production of impulses by neural tissue that is separated from afferent input. Impulses arise from the peripheral nervous system or central nervous system. Causes of neuropathic pain due to malignancy Neuropathic pain is caused directly by cancer-related pathology (compression/infiltration of nerve tissue, combination of compression/infiltration or by diagnostic and therapeutic procedures (surgical procedures, chemotherapy, radiotherapy. Mechanisms Pathophysiological mechanisms are very complex and still not clear enough. Neuropathic pain is generated by electrical hyperactivity of neurons along the pain pathways. Peripheral mechanisms (primary sensitization of nerve endings, ectopically generated action potentials within damaged nerves, abnormal electrogenesis within sensory ganglia and central mechanisms (loss of input from peripheral nociceptors into dorsal horn, aberrant sprouting within dorsal horn, central sensitization, loss of inhibitory interneurons, mechanisms at higher centers are involved. Diagnosis The quality of pain presents as spontaneous pain (continuous and paroxysmal, abnormal pain (allodynia, hyperalgesia, hyperpathia, paroxysmal pain. Clinical manifestations Clinically, neuropathic pain is described as the pain in the peripheral nerve (cranial nerves, other mononeuropathies, radiculopathy, plexopathy, paraneoplastic peripheral neuropathy and relatively infrequent, central pain syndrome. Therapy Treatment of neuropathic pain remains a challenge for clinicians, because there is no accepted algorithm for analgesic treatment of neuropathic pain. Pharmacotherapy is considered to be the first line therapy. Opioids combined with non-steroidal antiinflammatory drugs are warrented. If

    Systemic lupus erythematosus (SLE) is a clinically heterogeneous disease affecting multiple organ systems and characterized by autoantibody formation to nuclear components. Although genetic variation within the major histocompatibility complex (MHC) is associated with SLE, its role in the development of clinical manifestations and autoantibody production is not well defined. We conducted a meta-analysis of four independent European SLE case collections for associations between SLE sub-phenotypes and MHC single-nucleotide polymorphism genotypes, human leukocyte antigen (HLA) alleles and variant HLA amino acids. Of the 11 American College of Rheumatology criteria and 7 autoantibody sub-phenotypes examined, anti-Ro/SSA and anti-La/SSB antibody subsets exhibited the highest number and most statistically significant associations. HLA-DRB1*03:01 was significantly associated with both sub-phenotypes. We found evidence of associations independent of MHC class II variants in the anti-Ro subset alone. Conditional analyses showed that anti-Ro and anti-La subsets are independently associated with HLA-DRB1*0301, and that the HLA-DRB1*03:01 association with SLE is largely but not completely driven by the association of this allele with these sub-phenotypes. Our results provide strong evidence for a multilevel risk model for HLA-DRB1*03:01 in SLE, where the association with anti-Ro and anti-La antibody-positive SLE is much stronger than SLE without these autoantibodies.

    Objective: To analyze the pathogenic mechanism and the clinical significance of post-traumatic thoracolumbar syringomyelia through reviewing the clinical manifestations. Methods: The data of 15 patients (14 males and 1 female, aged from 28 to 56 years, with an average of 36 years) with post-traumatic syringomyelia treated in our hospital from December 1997 to February 2002 were studied retrospectively. Two patients suffered from T11 fractures, 7 from T12 fractures and 6 from L1 fractures. There were 12 patients with burst fractures and 3 with fracture dislocations. Anterior decompression, bone graft, bone fusion and internal fixation were made on 6 patients, posterior decompression, bone graft, bone fusion and internal fixation on 1 patient, and non-surgical treatment on 8 patients. Results: Syringomyelia of the patients was diagnosed accurately with magnetic resonance imaging at 0.5-4 years after the original thoracolumbar fracture. The cavern was round in 6 cases, elliptic in 6 cases, and irregular in 3 cases. The patients also suffered from pain (80%), myodynamia attenuation in lower extremities (66.7%), aggravated spasm (46.7%), sensation loss or hypesthesia (46.7%), decreased coordinate function of lower extremities (20%) and autonomic nerve symptom (6.7%).Conclusions: Post-traumatic thoracolumbar syringomyelia should be suspected if the patient has new neurological symptoms, such as myodynamia attenuation in lower extremities, after the neural function becomes stable for certain time.

    Full Text Available BACKGROUND AND OBJEC TIVES: It is a well - known fact that the skin is referred to as the mirror of the internal diseases. This study has undertaken with the objectives of knowing the spectrum of mucocutaneous manifestations in diabetes mellitus. METHODS: A total of 100 patients with dermatological manifestation were included in the study. Relevant investigation for the diagnosis of diabetes and dermatological disorders were done. RESULTS : Majority of the cases belonged to the age group 41 - 60 years. Various dermatoses observed in the patients were fungal, bacterial and viral infections, lichen planus, vitiligo, diabetic bullae and diabetic dermopathy, granuloma annulare, among the various cutaneous manifestations. Thirty four patients had associated systemic illness, hypertension being most commonly observed. INTERPRETATION AND CONCLUSION: A diabetic patient can present with both specific and non - specific dermatological manifestations. Thus a patient presenting with mucocutaneous manifestations in the absence of primary cutaneous disorders should be investigated for the underlying diabetic status . KEYWORDS : Diabetes; mucocutaneous Manifestations.

    Full Text Available Background : Cutaneous manifestations of deep mycotic infection are fraught with delayed or misdiagnosis from mainly cutaneous neoplastic lesions. Aim: This study is designed to present our experience of these mycoses in a pathology laboratory in the tropics. Materials and Methods : A clinicopathologic analysis of deep mycotic infections was conducted over a 15 years period Formalin fixed and paraffin wax processed biopsies were stained with hematoxylin and eosin, periodic acid Schiff (PAS, and Grocott′s methenamine silver (GMS for the identification of fungus specie. Patients′ bio-data and clinical information were obtained from records. Results : Twenty males and seven females presented with 6 months to 6 years histories of varying symptoms of slow growing facial swellings, nodules, subcutaneous frontal skull swelling, proptosis, nasal blockage, epistaxis, discharging leg sinuses, flank mass, convulsion and pain. Of the 27 patients, four gave antecedent history of trauma, two had recurrent lesions which necessitated maxilectomy, two presented with convulsion without motor dysfunction while one had associated erosion of the small bones of the foot. None of the patients had debilitating illnesses such as diabetes mellitus, tuberculosis, and HIV infection. Tissue histology revealed histoplasmosis (10, mycetoma (9, subcutaneous phycomycosis (6, and phaeohyphomycosis (2. Conclusion : Deep mycoses may present primarily as cutaneous lesions in immunocompetent persons and often elicit distinct histologic inflammatory response characterized by granuloma formation. Diagnosis in resource constraint setting can be achieved with tissue stained with PAS and GMS which identifies implicated fungus. Clinical recognition and adequate knowledge of the pathology of these mycoses may reduce attendant patient morbidity.

    Full Text Available Giant cell arteritis (GCA is a vasculitis affecting mainly large and medium-sized arteries, which the classification of systemic vasculitides refers to as those mainly involving the large vessels. GCA is typified by the involvement of extracranial aortic branches and intracranial vessels, the aorta and its large vessels are being affected most frequently. The paper considers the terminology, classification, prevalence, major pathogenic mechanisms, and morphology of GCA. A broad spectrum of its clinical subtypes is due to target vessel stenosis caused by intimal hyperplasia. In 40% of cases, GCA is shown to be accompanied by polymyalgia rheumatica that may either precede or manifest simultaneously with GCA, or follow this disease. The menacing complications of GCA may be visual loss or ischemic strokes at various sites depending on the location of the occluded vessel. Along with the gold standard verification of the diagnosis of GCA, namely temporal artery biopsy, the author indicates other (noninvasive methods for detection of vascular lesions: color Doppler ultrasonography of the temporal arteries, fluorescein angiography of the retina, mag-netic resonance angiography, magnetic resonance imaging, and computed tomography to rule out aortic aneurysm. Dynamic 18F positron emission tomography is demonstrated to play a role in the evaluation of therapeutic effectiveness.

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

    2001-01-01

    Epidemiologic surveys of temporomandibular disorders (TMD) have demonstrated that a considerable proportion of the population--up to 5% or 6%--will experience persistent pain severe enough to seek treatment. Unfortunately, the current diagnostic classification of craniofacial muscle pain is based on descriptions of signs and symptoms rather than on knowledge of pain mechanisms. Furthermore, the pathophysiology and etiology of craniofacial muscle pain are not known in sufficient detail to allow causal treatment. Many hypotheses have been proposed to explain cause-effect relationships; however, it is still uncertain what may be the cause of muscle pain and what is the effect of muscle pain. This article reviews the literature in which craniofacial muscle pain has been induced by experimental techniques in animals and human volunteers and in which the effects on somatosensory and motor function have been assessed under standardized conditions. This information is compared to the clinical correlates, which can be derived from the numerous cross-sectional studies in patients with craniofacial muscle pain. The experimental literature clearly indicates that muscle pain has significant effects on both somatosensory and craniofacial motor function. Typical somatosensory manifestations of experimental muscle pain are referred pain and increased sensitivity of homotopic areas. The craniofacial motor function is inhibited mainly during experimental muscle pain, but phase-dependent excitation is also found during mastication to reduce the amplitude and velocity of jaw movements. The underlying neurobiologic mechanisms probably involve varying combinations of sensitization of peripheral afferents, hyperexcitability of central neurons, and imbalance in descending pain modulatory systems. Reflex circuits in the brain stem seem important for the adjustment of sensorimotor function in the presence of craniofacial pain. Changes in somatosensory and motor function may therefore be

    The Department of Clinical Laboratory Sciences at Rosalind Franklin University of Medicine and Science (RFUMS) experienced a steady decline in the number of applicants for the Clinical Laboratory Sciences (CLS) Program, even though the department regularly received inquiries from qualified students. The faculty recognized the undergraduate-degreed prospects' desires for both an advanced degree and the procurement of entry-level clinical laboratory knowledge and skills. To address this perceived need, the CLS department developed and implemented a new degree option, the entry-level master's. The new curriculum resulted from a transformational process incorporated into the normal developmental process of curriculum change. This article explores various change theories that were manifested during this transformation process, along with barriers to change and how to overcome them. In addition, the authors demonstrate the need for creation of this entry-level program and provide a curriculum outline.

    Full Text Available BACKGROUND AND OBJECTIVES: Mucocutaneous manifestations are extremely common and varied in HIV infected patients. The present study was done to know the overall prevalence of mucocutaneous manifestations in HIV infected patients and to know the frequency of individual manifestations. METHODS: A total of 150 HIV seropositive patients from voluntary counseling and testing center were included in the study. Detailed history, thorough physical examination and relevant investigations were done to confirm the mucocutaneous manifestations when present. RESULTS: Ninety two percent (92% of 150 positives had mucocutaneous manifestations at presentation. Majority (75.34% of the patients belonged to the age group 25 – 49 years and male to female ratio was 1.08:1. Oral candidiasis was the most common (33.33% manifestation. Other common infectious conditions seen were HSV (16.67% dermatophytosis (12.67%, genital candidiasis (9.33%, herpes genitalis (10%. Common non-infectious disorders included generalized xerosis and ichthyosis (14.66%, generalized hyperpigmentation (11.33% and seborrheic dermatitis (6.67%. Hair and nail changes included diffuse alopecia (18%, trichomegaly (6.67% and melanonychia (32%.Pruritic papular dermatitis was seen in 16%. INTERPRETATION AND CONCLUSION: This study thus emphasizes the need for dermatological evaluation of all patients with HIV infection for early management and improved quality of life.

    Our knowledge of warts dates thousands of years. Most warts represent no more than a transient infection in the hands and feet of children and adults. With the relatively recent medical advances permitting the prolonged survival of immunocompromised hosts, however, HPV-induced lesions have become an important problem. In these patients, lesions represent a recurring, intractable infection that predisposes the patient to the development of skin cancer. Such problems have been appreciated for some time in patients with EV. Newer laboratory techniques have led to an increasing number of clinical entities linked with an HPV cause in the nonimmunosuppressed host. Although evidence incriminating HPV as a causative factor for genital cancers of the cervix and the skin continues to mount, such evidence for nongenital Bowen's disease, certain squamous cell carcinomas of the skin, keratoacanthomas, and other tumors of the skin also has begun to grow. It is to be hoped that continued advances in molecular biologic techniques will further delineate the relationship between HPV and these conditions, lead to an HPV classification scheme that is more utilitarian from a clinical point of view, and ultimately lead to improved treatment.

    Full Text Available BACKGROUND: In Brazil, lethality from visceral leishmaniasis (VL is high and few studies have addressed prognostic factors. This historical cohort study was designed to investigate the prognostic factors for death from VL in Belo Horizonte (Brazil. METHODOLOGY: The analysis was based on data of the Reportable Disease Information System-SINAN (Brazilian Ministry of Health relating to the clinical manifestations of the disease. During the study period (2002-2009, the SINAN changed platform from a Windows to a Net-version that differed with respect to some of the parameters collected. Multivariate logistic regression models were performed to identify variables associated with death from VL, and these were included in prognostic score. PRINCIPAL FINDINGS: Model 1 (period 2002-2009; 111 deaths from VL and 777 cured patients included the variables present in both SINAN versions, whereas Model 2 (period 2007-2009; 49 deaths from VL and 327 cured patients included variables common to both SINAN versions plus the additional variables included in the Net version. In Model 1, the variables significantly associated with a greater risk of death from VL were weakness (OR 2.9; 95%CI 1.3-6.4, Leishmania-HIV co-infection (OR 2.4; 95%CI 1.2-4.8 and age ≥60 years (OR 2.5; 95%CI 1.5-4.3. In Model 2, the variables were bleeding (OR 3.5; 95%CI 1.2-10.3, other associated infections (OR 3.2; 95%CI 1.3-7.8, jaundice (OR 10.1; 95%CI 3.7-27.2 and age ≥60 years (OR 3.1; 95%CI 1.4-7.1. The prognosis score was developed using the variables associated with death from VL of the latest version of the SINAN (Model 2. The predictive performance of which was evaluated by sensitivity (71.4%, specificity (73.7%, positive and negative predictive values (28.9% and 94.5% and area under the receiver operating characteristic curve (75.6%. CONCLUSIONS: Knowledge regarding the factors associated with death from VL may improve clinical management of patients and contribute to lower

    Imagine a clinical microbiology laboratory where a patient's specimens are placed on a conveyor belt and sent on an automation line for processing and plating. Technologists need only log onto a computer to visualize the images of a culture and send to a mass spectrometer for identification. Once a pathogen is identified, the system knows to send the colony for susceptibility testing. This is the future of the clinical microbiology laboratory. This article outlines the operational and staffing challenges facing clinical microbiology laboratories and the evolution of automation that is shaping the way laboratory medicine will be practiced in the future.

    2016-06-01

    Autoimmune disorders are not commonly encountered in a general pediatric practice, but they may mimic many other disorders. Although they occur infrequently, it is always important to pause and consider an autoimmune disorder in the differential diagnosis. A detailed history and careful physical examination play an important role in guiding laboratory evaluation for these disorders. Many autoimmune disorders present with symptoms that involve multiple organ systems. The common symptoms that may make one consider a rheumatic disorder in the differential diagnosis are fever, fatigue, joint pain, rash, ulcers, and muscle weakness. The most common reason for referral to a pediatric rheumatologist is joint pain. A good joint examination may be performed by the use of the pediatric Gait, Arms, Legs, Spine screen, which is a validated screening tool. A small portion of children with fever of unknown origin may have an autoimmune disorder, with a majority of them having an infectious disease. Some patients with undiagnosed rheumatic disorders may present to the emergency. department. The characteristics of historic and clinical examination features of various autoimmune disorders are discussed in this article. [Pediatr Ann. 2016;45(6):e223-e229.].

    Full Text Available BACKGROUND: Infections caused by non-O1 Vibrio cholera are uncommon. The aim of our study was to investigate the clinical and microbiological characteristics of patients with non-O1 V. cholera infections. METHODS: The clinical charts of all patients with non-O1 V. cholera infections and who were treated in two hospitals in Taiwan were retrospectively reviewed. RESULTS: From July 2009 to June 2014, a total of 83 patients with non-O1 V. cholera infections were identified based on the databank of the bacteriology laboratories of two hospitals. The overall mean age was 53.3 years, and men comprised 53 (63.9% of the patients. Liver cirrhosis and diabetes mellitus were the two most common underlying diseases, followed by malignancy. The most common type of infection was acute gastroenteritis (n = 45, 54.2%, followed by biliary tract infection (n = 12, 14.5% and primary bacteremia (n = 11, 13.3%. Other types of infection, such as peritonitis (n = 5, 6.0%, skin and soft tissue infection (SSTI (n = 5, 6.0%, urinary tract infection (n = 3, 3.6% and pneumonia (2, 2.4%, were rare. July and June were the most common months of occurrence of V. cholera infections. The overall in-hospital mortality of 83 patients with V. cholera infections was 7.2%, but it was significantly higher for patients with primary bacteremia, hemorrhage bullae, acute kidney injury, acute respiratory failure, or admission to an ICU. Furthermore, multivariate analysis showed that in-hospital mortality was significantly associated with acute respiratory failure (odds ratio, 60.47; 95% CI, 4.79-763.90, P = 0.002. CONCLUSIONS: Non-O1 V. cholera infections can cause protean disease, especially in patients with risk factors and during warm-weather months. The overall mortality of 83 patients with non-O1 V. cholera infections was only 7.2%; however, this value varied among different types of infection.

    The clinical presentation of hepatocellular carcinoma (HCC differs between patients in developing countries (African and Chinese populations from those in industrialized countries. In industrialized countries, HCC co-exists with symptomatic cirrhosis in 80% of cases and clinical manifestations are usually related to those of the underlying disease. On the other hand, patients from developing countries have HCC and cirrhosis in approximately 40% of cases. Underlying cirrhosis in many cases is not advanced and does not produce any symptoms or associated symptoms are masked by those of the tumor (right upper quadrant pain, mass in the upper abdomen, weight loss and weakness. In a subset of patients, there are no clinical manifestations as HCC may occur in the context of hepatitis B infection without cirrhosis.

    Clinical Manifestations

    In Western countries, nearly 35% percent of patients with HCC are asymptomatic. Some of the most common clinical manifestations include: abdominal pain (53-58% of patients, especially in epigastrium or right upper quadrant, abdominal mass (30%, weight loss, malaise, anorexia, cachexia, jaundice or fever.

    Physical Exam

    Physical findings vary with the stage of disease. The patient may exhibit slight or moderate wasting when first seen. In patients with cirrhosis, typical stigmata of chronic liver disease may be present. In advanced stages of HCC the liver may be enlarged and there is significant tenderness. An arterial bruit may be heard over the liver

    Full Text Available Introduction: The Clinical and radiological manifestations of newborns with severe VDD have not been studied well. Materials and Methods: We studied the clinical, biochemical, and radiological manifestations of 10 full-term (FT newborns (6: M, 4: F infant presented to with symptomatic hypocalcemia (seizure secondary to vitamin D deficiency (VDD during the first 10 days of life are described. All were exclusively breastfed since birth. All their mothers have low 25 hydroxy vitamin D (25OHD level 60 ng/mL and 60% had decreased magnesium (Mg concentrations (<0.7 mmol/L. Their alkaline phosphatase (ALP concentrations were significantly higher than normal newborns. All other laboratory results (liver function tests, urea and electrolytes, C reactive protein, lumbar puncture, blood culture, and lactate were normal. In all patients, seizures ceased within 2 days of starting treatment with alphacalcidol and calcium. Radiological manifestations included metaphyseal band of relative lucency (osteopenia, just under the line of provisional calcification, within distal radius (7/10, femur (4/10, and tibia (3/10, mild cupping and haziness of distal radius (2/10. Discussion: Newborns with VDD had significantly lower serum calcium, ALP and PTH and higher phosphate concentrations, compared to older infants with VDD rickets. In newborns with VDD, serum calcium levels were correlated significantly with 25OHD (r = 0.597, P < 0.001, Mg concentrations (r = 0.436, P < 0.001 and negatively with ALP concentrations (r = −0.451, P < 0.001. Serum PTH concentrations were correlated significantly with serum Mg (r = 0.78, P < 0.0001 but not with serum calcium (r = −0.103, P = 0.3 or 25OHD (r = −0.03, P = 0.7 concentrations. Conclusion: The clinical, biochemical, and radiological manifestations of VDD in newborns indicate that they are less adapted to VDD compared to older infants. VD supplementation for mothers and newborns should be considered to avoid short

  3. Risk Management in the Clinical Laboratory

    Clinical laboratory tests play an integral role in medical decision-making and as such must be reliable and accurate. Unfortunately, no laboratory tests or devices are foolproof and errors can occur at pre-analytical, analytical and post-analytical phases of testing. Evaluating possible conditions that could lead to errors and outlining the necessary steps to detect and prevent errors before they cause patient harm is therefore an important part of laboratory testing. This can be achieved through the practice of risk management. EP23-A is a new guideline from the CLSI that introduces risk management principles to the clinical laboratory. This guideline borrows concepts from the manufacturing industry and encourages laboratories to develop risk management plans that address the specific risks inherent to each lab. Once the risks have been identified, the laboratory must implement control processes and continuously monitor and modify them to make certain that risk is maintained at a clinically acceptable level. This review summarizes the principles of risk management in the clinical laboratory and describes various quality control activities employed by the laboratory to achieve the goal of reporting valid, accurate and reliable test results.

    The application of simple, cost-effective, rapid, and accurate diagnostic technologies for detection and identification of cardiac and cancer biomarkers has been a central point in the clinical area. Biosensors have been recognized as efficient alternatives for the diagnostics of various diseases due to their specificity and potential for application on real samples. The role of nanotechnology in the construction of immunological biosensors, that is, immunosensors, has contributed to the improvement of sensitivity, since they are based in the affinity between antibody and antigen. Other analytes than biomarkers such as hormones, pathogenic bacteria, and virus have also been detected by immunosensors for clinical point-of-care applications. In this chapter, we first introduced the various types of immunosensors and discussed their applications in clinical diagnostics over the recent 6 years, mainly as point-of-care technologies for the determination of cardiac and cancer biomarkers, hormones, pathogenic bacteria, and virus. The future perspectives of these devices in the field of clinical diagnostics are also evaluated.

    Worldwide, more than 1.9 billion adults are overweight, and around 600 million people suffer from obesity. Similarly, ~382 million individuals live with diabetes, and 40-50% of the global population is labeled at "high risk" (i.e., prediabetes). The impact of these two chronic conditions relies not only on the burden of illnesses per se (i.e., associated increased morbidity and mortality), but also on their increased cost, burden of treatment, and decreased health-related quality of life. For this review a comprehensive search in several databases including PubMed (MEDLINE), Ovid EMBASE, Web of Science, and Scopus was conducted. In both diabetes and obesity, genetic, epigenetic, and environmental factors overlap and are inclusive rather than exclusive. De facto, 70-80% of the patients with obesity and virtually every patient with type 2 diabetes have insulin resistance. Insulin resistance is a well-known pathophysiologic factor in the development of type 2 diabetes, characteristically appearing years before its diagnosis. The gold standard for insulin resistance diagnosis (the euglycemic insulin clamp) is a complex, invasive, costly, and hence unfeasible test to implement in clinical practice. Likewise, laboratory measures and derived indexes [e.g., homeostasis model assessment of insulin resistance (HOMA-IR-)] are indirect, imprecise, and not highly accurate and reproducible tests. However, skin manifestations of insulin resistance (e.g., acrochordons, acanthosis nigricans, androgenetic alopecia, acne, hirsutism) offer a reliable, straightforward, and real-time way to detect insulin resistance. The objective of this review is to aid clinicians in recognizing skin manifestations of insulin resistance. Diagnosing these skin manifestations accurately may cascade positively in the patient's health by triggering an adequate metabolic evaluation, a timely treatment or referral with the ultimate objective of decreasing diabetes and obesity burden, and improving the

    Since the earliest reports in 2001, immunoglobulin G4 (IgG4)-related disease has been defined as an autoimmune systemic disease characterized by the lymphoplasmacytic infiltration of affected tissues leading to fibrosis and obliterative phlebitis along with elevated serum IgG4 levels. Prior to this unifying hypothesis, a plethora of clinical manifestations were considered as separate entities despite the similar laboratory profile. The pathology can be observed in virtually all organs and may thus be a challenging diagnosis, especially when the adequate clinical suspicion is not present or when obtaining a tissue biopsy is not feasible. Nonetheless, the most frequently involved organs are the pancreas and exocrine glands but these may be spared. Immunosuppressants lead to a prompt clinical response in virtually all cases and prevent histological sequelae and, as a consequence, an early differential diagnosis from other conditions, particularly infections and cancer, as well as an early treatment should be pursued. We describe herein two cases in which atypical disease manifestations were observed, i.e., one with recurrent neck lymph node enlargement and proptosis, and one with jaundice. Our understanding of the pathogenesis of IgG4-related disease is largely incomplete but data support a significant role for Th2 cytokines with the contribution of innate immunity factors such as Toll-like receptors, macrophages and basophils. Further, macrophages activated by IL4 overexpress B cell activating factors and contribute to chronic inflammation and the development of fibrosis. We cannot rule out the possibility that the largely variable disease phenotypes reflect different pathogenetic mechanisms and the tissue microenvironment may then contribute to the organ involvement.

    Full Text Available Introduction. Turner syndrome is a chromosomal abnormality where all or a part of one of the X chromosomes is absent or it has other abnormalities. Besides characteristic abnormalities of short stature and infertility, women with Turner syndrome have increased risks for tumors of the central nervous system, especially meningioma and an otologic disease. Meningioma involving the middle ear is extremely rare, and this condition has never been published in association with Turner syndrome. Case Report. We present an otologic manifestation associated with other abnormalities in a patient with Turner syndrome and discuss diagnosis and possible treatment options. Conclusion. Multidisciplinary team approach is essential in these patients in order to evaluate their vulnerability and define therapeutic priorities.

    The design of a decision support system for capacity planning in clinical laboratories is discussed. The DSS supports decisions concerning the following questions: how should the laboratory be divided into job shops (departments/sections), how should staff be assigned to workstations and how should samples be assigned to workstations for testing. The decision support system contains modules for supporting decisions at the overall laboratory level (concerning the division of the laboratory into job shops) and for supporting decisions at the job shop level (assignment of staff to workstations and sample scheduling). Experiments with these modules are described showing both the functionality and the validity.

    Hyperthyroidism was diagnosed in four guinea pigs by demonstration of an increased serum total thyroxine concentration. The main clinical signs were comparable with those observed in feline hyperthyroidism and included weight loss despite maintenance of appetite and a palpable mass in the ventral cervical region. Three animals were treated successfully with methimazole for between 13 and 28 months. Clinical signs and regular measurement of circulating total thyroxine concentrations appear to be convenient parameters for monitoring response to medical therapy.

    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

    Clinical laboratories provide an invaluable service to millions of people around the world in the form of quality diagnostic care. Within the clinical laboratory industry the impetus for change has come from technological development (miniaturization, nanotechnology, and their collective effect on point-of-care testing; POCT) and the increasingly global nature of laboratory services. Potential technological gains in POCT include: the development of bio-sensors, microarrays, genetics and proteomics testing, and enhanced web connectivity. In globalization, prospective opportunities lie in: medical tourism, the migration of healthcare workers, cross-border delivery of testing, and the establishment of accredited laboratories in previously unexplored markets. Accompanying these impressive opportunities are equally imposing challenges. Difficulty transitioning from research to clinical use, poor infrastructure in developing countries, cultural differences and national barriers to global trade are only a few examples. Dealing with the issues presented by globalization and the impact of developing technology on POCT, and on the clinical laboratory services industry in general, will be a daunting task. Despite such concerns, with appropriate countermeasures it will be possible to address the challenges posed. Future laboratory success will be largely dependent on one's ability to adapt in this perpetually shifting landscape.

    Over the past 15 years, CE as an analytical tool has shown great promise in replacing many conventional clinical laboratory methods, such as electrophoresis and HPLC. CE's appeal was that it was fast, used very small amounts of sample and reagents, was extremely versatile, and was able to separate large and small analytes, whether neutral or charged. Because of this versatility, numerous methods have been developed for analytes that are of clinical interest. Other than molecular diagnostic and forensic laboratories CE has not been able to make a major impact in the United States. In contrast, in Europe and Japan an increasing number of clinical laboratories are using CE. Now that automated multicapillary instruments are commercially available along with cost-effective test kits, CE may yet be accepted as an instrument that will be routinely used in the clinical laboratories. This review will focus on areas where CE has the potential to have the greatest impact on the clinical laboratory. These include analyses of proteins found in serum and urine, hemoglobin (A1c and variants), carbohydrate-deficient transferrin, forensic and therapeutic drug screening, and molecular diagnostics.

    Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is one of the most frequent maternally inherited mitochondrial disorders. MELAS syndrome is a multi-organ disease with broad manifestations including stroke-like episodes, dementia, epilepsy, lactic acidemia, myopathy, recurrent headaches, hearing impairment, diabetes, and short stature. The most common mutation associated with MELAS syndrome is the m.3243A>G mutation in the MT-TL1 gene encoding the mitochondrial tRNA(Leu(UUR)). The m.3243A>G mutation results in impaired mitochondrial translation and protein synthesis including the mitochondrial electron transport chain complex subunits leading to impaired mitochondrial energy production. The inability of dysfunctional mitochondria to generate sufficient energy to meet the needs of various organs results in the multi-organ dysfunction observed in MELAS syndrome. Energy deficiency can also stimulate mitochondrial proliferation in the smooth muscle and endothelial cells of small blood vessels leading to angiopathy and impaired blood perfusion in the microvasculature of several organs. These events will contribute to the complications observed in MELAS syndrome particularly the stroke-like episodes. In addition, nitric oxide deficiency occurs in MELAS syndrome and can contribute to its complications. There is no specific consensus approach for treating MELAS syndrome. Management is largely symptomatic and should involve a multidisciplinary team. Unblinded studies showed that l-arginine therapy improves stroke-like episode symptoms and decreases the frequency and severity of these episodes. Additionally, carnitine and coenzyme Q10 are commonly used in MELAS syndrome without proven efficacy.

    Chromoblastomycosis is one of the most frequent infections caused by melanized fungi. It is a subcutaneous fungal infection, usually an occupational related disease, mainly affecting individuals in tropical and temperate regions. Although several species are etiologic agents, Fonsecaea pedrosoi and Cladophialophora carrionii are prevalent in the endemic areas. Chromoblastomycosis lesions are polymorphic and must be differentiated from those associated with many clinical conditions. Diagnosis is confirmed by the observation of muriform cells in tissue and the isolation and the identification of the causal agent in culture. Chromoblastomycosis still is a therapeutic challenge for clinicians due to the recalcitrant nature of the disease, especially in the severe clinical forms. There are three treatment modalities, i.e., physical treatment, chemotherapy and combination therapy but their success is related to the causative agent, the clinical form and severity of the chromoblastomycosis lesions. There is no treatment of choice for this neglected mycosis, but rather several treatment options. Most of the patients can be treated with itraconazole, terbinafine or a combination of both. It is also important to evaluate the patient's individual tolerance of the drugs and whether the antifungal will be provided for free or purchased, since antifungal therapy must be maintained in long-term regimens. In general, treatment should be guided according to clinical, mycological and histopathological criteria.

    Antiphospholipid syndrome is a relatively recent systemic autoimmune disorder defined by thrombotic events and/or obstetric complications in the presence of persistent elevated antiphospholipid antibodies. It\\'s characterized by a wide spectrum of clinical presentations and virtually any organ system or tissue may be affected by the consequences of vascular occlusion. Diagnosis is sometimes difficult and although classification criteria have been published and revised there remain ongoing issues regarding nomenclature, expanding clinical features, laboratory tests and management and much still has to be done. Cutaneous manifestations are common and frequently the first sign of the disease. Although extremely diverse it\\'s important to know which dermatological findings should prompt consideration of antiphospholipid syndrome and the appropriate management for those patients. Much has been debated about when to consider antiphospholipid syndrome and consensus still does not exist, however in spite of being a diagnostic challenge clinicians should know when to look for antiphospholipid antibodies since an early diagnosis is important to prevent further and serious complications. In this article we focus on the cutaneous features that should raise suspicion on the presence of antiphospholipid syndrome and on the complex management of such patients. Many other dermatological signs related to this syndrome have been described in the literature but only occasionally and without consistency or statistic impact and therefore will not be considered here.

  7. Clinical manifestations of hysteria: an epistemological perspective or how historical dynamics illuminate current practice.

    Hysteria has generated the most heated debates among physicians, from antiquity to the present day. It has been long confused with neuroses and neurological pathologies such as Parkinson's disease and epilepsy, principally associated with women and sexual disorders. The clinical manifestations must first be seen in their historical context, as interpretation varies according to the time period. Recently, the Diagnostic and Statistical Manual of Mental Disorders by the American Psychiatric Association marked a break in the consensus that previously seemed to apply to the concept of hysteria and approach to the clinical manifestations. The clinical manifestations of hysteria are numerous and multifaceted, comprising 3 main classifications: paroxysms, attacks, and acute manifestations; long-lasting functional syndromes, and visceral events. Each main classification can be subdivided into several subgroups. The first main group of paroxysms, attacks, and acute manifestations includes major hysterical attacks, such as prodrome, trance and epileptic states, minor hysterical attacks such as syncope and tetany, twilight states, paroxysmal amnesia, and cataleptic attacks. The second group includes focal hysterical symptoms, paralyses, contractures and spasms, anesthesia, and sensory disorders. Visceral manifestations can be subdivided into spasms, pain, and general and trophic disorders. The diversity of the symptoms of hysteria and its changing clinical presentation calls into question the same hysterical attacks and the same symptoms, which have had only a few differences for over 2,000 years. A new definition of hysteria should be proposed, in that it is a phenomenon that is not pathological, but physiological and expressional.

    Full Text Available BACKGROUND: Lymphomas are one of the commonest childhood malignancies. Due to varied clinical features many patients are misdiagnosed and treated for other diseases. It is imperative to keep health workers informed about the current trend of lymphomas in northeastern Nigeria to facilitate prompt diagnosis and treatment. OBJECTIVE: To evaluate the extent of lymphomas at presentation and to define the pattern of presentation in relation to gender and site. MATERIALS AND METHODS: Retrospective analysis of cases of lymphomas over a 15 year period was conducted. Structured questionnaires were used to document demographic characteristics and clinical features. The non-Hodgkin's lymphoma (NHL and Hodgkin's lymphoma (HL cases were categorized using standard classification schemes. Data were analyzed using the Statistical Package for Social Sciences (SPSS software version 16, Illinois, Chicago, USA. Spearman's correlation and Student's t-test were applied where appropriate. A P value < 0.05 was considered significant. RESULTS: Fifty cases of lymphoma, 10 (20% belong to HL and 40 (80% belong to NHL. Lymphoma is common in male, though the male to female preponderance was not significant in both the cases (P = 0.107 and 0.320, respectively. Maxilla was the commonest site of primary malignancy (36% and late presentation of patients were observed. New trend was noticed, the NHL patients present commonly with severe symptoms than HL (P = 0.038. HL was dominated by lymphocytic predominant type, while NHL was dominated by the small non cleaved cells (Burkitt's lymphoma (70%. CONCLUSION: Childhood lymphoma in northeastern Nigeria has a slight shift in varied clinical presentation in favor of NHL. Patients in this study had late presentation.

    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.

    On the basis of analysis of presentation and surgical treatment of 103 patients with lumbar disc herniation the authors performed comparative assessment of symptoms and therapeutic techniques in patients with higher and lower lumbar disc disease. Short-term and long-term results were evaluated using visual analogue scale and Oswestry disability index (ODI). Statistically significant differences in dynamics of pain and ODI were not present. In spite of differences in clinical presentation, the results of surgical treatment in both groups were similar. They depended on severity of preoperative neurological deficit regardless of level of lesion. Specific features of surgical procedure in superior lumbar disk herniation are described.

    Amphiphysin antibody causes paraneoplastic stiff-person syndrome and can also result in a variety of neurological manifestations. Here, we investigated the clinical spectrum of 20 patients with non-stiff anti-amphiphysin syndrome and their responses to immunotherapy. The most common neurological manifestation was limbic encephalitis (n=10), followed by dysautonomia (n=9), and cerebellar dysfunction (n=6). Cancer was detected in only seven patients. Intravenous immunoglobulin or steroid treatment was effective in most patients, but three improved only after rituximab treatment. Our study suggests that anti-amphiphysin syndrome can manifest as non-stiff encephalomyelitis and is only partially associated with cancer. Active immunotherapy, including rituximab, would be beneficial.

    2009-09-01

    Full Text Available Abstract The Gasperini syndrome is a very rare brainstem disease characterized by the typical combination of ipsilateral lesions of the cranial nerves V-VII and dissociated contralateral hemihypesthesia, whereas both contralateral and ipsilateral hypacusis was described. Since the first description in 1912, only a few cases of this crossed brainstem syndrome were published so far. Pontine infarction and bleedings were the reported causes of the syndrome. Here we report a 44-year-old man with the classical Gasperini syndrome due to pontine demyelination in multiple sclerosis. The clinical findings were correlated with changes on MRI. The present case shows that classical crossed brainstem syndromes are topological terms not invariably associated with brainstem ischemia in particular vascular areas and may contribute to the differential diagnosis of peripheral facial nerve palsy.

    Full Text Available Objective: to provide the clinical characteristics of joint injury in patients with calcium pyrophosphate crystal (CPC deposition disease.Subjects and methods. The trial enrolled 68 patients (43 women, 25 men with a verified diagnosis of CPC deposition disease. Their mean age was 60.2±11.8 years and disease duration was 7.5±6.4 years. Examination revealed the presence of arthritis and arthralgias. Polarizing microscopy with an Olympus CX31-P compensator was used to detectcrystals in synovial fluid. X-ray study of the knee joints was performed in the anteroposterior and lateral projections and that of the hand joints was in the frontal projection, Ultrasonography (USG of the knee and wrist joints was done using a GE Voluson-I transducer.Results. A concurrence of arthritis and arthralgias was noted in 37 (54% patients; 24 (36% patients had arthralgias only; 7 (10% had arthritis only. Arthritis affecting the knee, wrist, ankle, and first metacarpophalangeal joints was observed in 53, 15, 12, and 6% of cases, respectively. There was acute arthritis in 18% of the patients and chronic arthritis in 39%; the rate of CPC osteoarthrosis was 43%. Joint USG diagnosed knee and wrist joint chondrocalcinosis in 94 and 56% of the patients, respectively. USG could reveal asymptomatic wrist joint chondrocalcinosis significantly more often (in 56 and 17% of the patients, respectively; p = 0.008. Besides, USG could visualize synovitis in the knee joints in 88% of the patients with isolated arthralgias in them and synovitis in the wrinkle joints in 52% of the patients without clinical signs of inflammation in them.Conclusion. Osteoarthrosis is the most common form of CPC deposition disease. Knee joints in this disease are most frequently involved. Joint USG is of more informative value in detecting chondrocalcinosis than X-ray study; USG can also identify synovitis in the intact joints.

    Pyruvate kinase deficiency is the most frequent enzyme abnormality of the Embden-Meyerhof pathway causing hereditary non-spherocytic haemolytic anaemia. The degree of haemolysis varies widely, ranging from very mild or fully compensated forms, to life-threatening neonatal anaemia and jaundice necessitating exchange transfusions. Splenectomy should be reserved for young patients who require regular blood transfusions. The gene encoding for pyruvate kinase (PK-LR) has been localized to the long arm of chromosome I; the cDNA of R-type is 2060 bp long and codes for 574 amino acids. More than 130 different mutations, mostly missense, have so far been described in association with PK deficiency, 1529A and 1456T being considered to be the most common mutations in Caucasians. Analysis of the three-dimensional structure of the enzyme may help in predicting the severity of the molecular defect. Further data on clinical features of homozygous patients are needed, at least for some mutations, to allow a more precise genotype/phenotype correlation.

    Background Disease caused by the dengue virus (DENV) is a significant cause of morbidity throughout the world. Although prior research has focused on the association of specific DENV serotypes (DENV-1, DENV-2, DENV-3, and DENV-4) with the development of severe outcomes such as dengue hemorrhagic fever and dengue shock syndrome, relatively little work has correlated other clinical manifestations with a particular DENV serotype. The goal of this study was to estimate and compare the prevalence of non-hemorrhagic clinical manifestations of DENV infection by serotype. Methodology and Principal Findings Between the years 2005–2010, individuals with febrile disease from Peru, Bolivia, Ecuador, and Paraguay were enrolled in an outpatient passive surveillance study. Detailed information regarding clinical signs and symptoms, as well as demographic information, was collected. DENV infection was confirmed in patient sera with polyclonal antibodies in a culture-based immunofluorescence assay, and the infecting serotype was determined by serotype-specific monoclonal antibodies. Differences in the prevalence of individual and organ-system manifestations were compared across DENV serotypes. One thousand seven hundred and sixteen individuals were identified as being infected with DENV-1 (39.8%), DENV-2 (4.3%), DENV-3 (41.5%), or DENV-4 (14.4%). When all four DENV serotypes were compared with each other, individuals infected with DENV-3 had a higher prevalence of musculoskeletal and gastrointestinal manifestations, and individuals infected with DENV-4 had a higher prevalence of respiratory and cutaneous manifestations. Conclusions/Significance Specific clinical manifestations, as well as groups of clinical manifestations, are often overrepresented by an individual DENV serotype. PMID:22563516

    The diagnostic laboratories in India are progressively promoting higher standards and are moving towards accreditation and international acceptance. Hence, the concept of "Quality" will need to be understood and implemented. Total quality management (TQM) in a laboratory is an integrated program involving all laboratory staff and management. TQM is a framework to operate and it is aiming for integration, consistency, increase in efficiency and a continuous drive for improvement. A well structured clinical virology service will include serology setup, cell culture facility and capacity for molecular diagnosis. The quality of results from the laboratory is significantly influenced by many pre-analytical and post-analytical factors which needed attention. The end goal of the TQM should be to provide the best care possible for the patient.

    Full Text Available ABSTRACT: BACKGROUND: Pregnancy is a period of profound immunologic, endocr ine, metabolic and vascular changes which are tolerated by the body for a relatively short time. Almost all pregnant women (90% may develop both physiologic and pathologic changes in the skin, nails, and hair which should be recognized and appropriately m anaged 1 . Moreover, pregnancy modifies the course of a number of pre - existing dermatological conditions. AIMS: To find out the frequency and pattern of skin changes in pregnant women i.e. physiological skin changes, dermatoses modified by pregnancy and spec ific dermatoses of pregnancy . DESIGN: Prospective descriptive study . METHODS AND MATERIAL: A total of 300 pregnant women attending antenatal OPD and those admitted in wards having symptoms related to skin and mucosa, at tertiary care centre between June 20 11 and November 2012 were studied. Patients not willing to give informed consent were only excluded. . Detailed history, clinical examination and relevant investigations were done. RESULTS: In our study age distribution of pregnancy, was in range of 16 - 30 years. Most of the cases belonged to 2 nd and 3 rd trimester (93%. Pigmentary changes were the most common non specific pregnancy dermatosis, seen in almost all cases. Of these linea nigra (87% being the commonest. Overall 54 cases showed specific dermatos es of pregnancy. Of these the most common was prurigo of pregnancy (12% followed by pruritus of pregnancy (4%, PUPPP (2%. Among the other dermatological conditions, scabies (16% was the commonest. Fungal infections were seen in 14%, viral infections in 8% and bacterial infections in 5%. CONCLUSION: Majority of the dermatoses associated with pregnancy were observed in third trimester and among multigravidas. Pigmentary changes was the commonest physiological change observed. Prurigo of pregnancy was the commonest specific dermatosis of pregnancy. There were no cases of dermatoses modified during pregnancy

    Although Morganella morganii causes a variety of clinical infections, there are limited studies on M. morganii bacteremia after the year 2000. A total of 109 patients with M. morganii bacteremia at a medical center in Taiwan from 2003 to 2012 were studied. Among them, 30.3 % had polymicrobial bacteremia and 75.2 % had community-acquired infection. The most common underlying diseases were hypertension (62.4 %) and diabetes mellitus (38.5 %). The urinary tract (41.3 %) was the major portal of entry, followed by the hepatobiliary tract (27.5 %), skin and soft tissue (21.1 %), and primary bacteremia (10.1 %). Susceptibility testing of M. morganii isolates showed ubiquitous resistance to first-generation cephalosporins and ampicillin-clavulanate; resistance rates to gentamicin, piperacillin-tazobactam, and ciprofloxacin were 30.3 %, 1.8 %, and 10.1 %, respectively. Overall, the 14-day mortality was 14.7 %. Univariate analysis revealed that elevated blood urea nitrogen (BUN) values [p = 0.0137, odds ratio (OR) 5.26], intensive care unit (ICU) admission (p = 0.011, OR 4.4), and higher Acute Physiology and Chronic Health Evaluation II (APACHE II) scores (p < 0.001, OR 1.62) were significantly associated with mortality. The APACHE II score remained the only significant risk factor for mortality in multivariate analysis (p = 0.0012, OR 1.55). In conclusion, M. morganii bacteremia patients were mostly elderly, with one or more comorbidities. Most of the patients had community-acquired infection via the urinary and hepatobiliary tracts. Furthermore, prognosis can be predicted according to disease severity measured by the APACHE II score.

    Full Text Available Abstract Background Plasmodium falciparum can be detected by microscopy, histidine-rich-protein-2 (HRP2 capture test or PCR but the respective clinical relevance of the thereby diagnosed infections in pregnant women is not well established. Methods In a cross-sectional, year-round study among 839 delivering women in Agogo, Ghana, P. falciparum was screened for in both, peripheral and placental blood samples, and associations with maternal anaemia, low birth weight (LBW and preterm delivery (PD were analysed. Results In peripheral blood, P. falciparum was observed in 19%, 34%, and 53% by microscopy, HRP2 test, and PCR, respectively. For placental samples, these figures were 35%, 41%, and 59%. Irrespective of diagnostic tool, P. falciparum infection increased the risk of anaemia. Positive peripheral blood results of microscopy and PCR were not associated with LBW or PD. In contrast, the HRP2 test performed well in identifying women at increased risk of poor pregnancy outcome, particularly in case of a negative peripheral blood film. Adjusting for age, parity, and antenatal visits, placental HRP2 was the only marker of infection associated with LBW (adjusted odds ratio (aOR, 1.5 (95%CI, 1.0–2.2 and, at borderline statistical significance, PD (aOR, 1.4 (1.0–2.1 in addition to anaemia (aOR, 2.3 (1.7–3.2. Likewise, HRP2 in peripheral blood of seemingly aparasitaemic women was associated with PD (aOR, 1.7 (1.0–2.7 and anaemia (aOR, 2.1 (1.4–3.2. Conclusion Peripheral blood film microscopy not only underestimates placental malaria. In this highly endemic setting, it also fails to identify malaria as a cause of foetal impairment. Sub-microscopic infections detected by a HRP2 test in seemingly aparasitaemic women increase the risks of anaemia and PD. These findings indicate that the burden of malaria in pregnancy may be even larger than thought and accentuate the need for effective anti-malarial interventions in pregnancy.

    Eosinophilic meningitis, caused by the nematode Angiostrongylus cantonensis, is prevalent in northeastern Thailand, most commonly in adults. Data regarding clinical manifestations of this condition in children is limited and may be different those in adults. A chart review was done on 19 eosinophilic meningitis patients aged less than 15 years in Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Thailand. Clinical manifestations and outcomes were reported using descriptive statistics. All patients had presented with severe headache. Most patients were males, had fever, nausea or vomiting, stiffness of the neck, and a history of snail ingestion. Six patients had papilledema or cranial nerve palsies. It was shown that the clinical manifestations of eosinophilic meningitis due to A. cantonensis in children are different from those in adult patients. Fever, nausea, vomiting, hepatomegaly, neck stiffness, and cranial nerve palsies were all more common in children than in adults.

    Full Text Available Background. Kawasaki disease (KD is an acute systemic vasculitis with unknown etiology. The diagnosis of KD depends on clinical manifestations. The prevalence of coronary artery abnormality (CAA is 11.0% and results in cardiac sequelae, such as myocardial infarction or coronary aneurysm, which are the most serious complications in KD. Methods. We divided KD's children into different age groups: ≤6 months old, 7 months to 1 year old, and >1 year old, respectively. Different parameters were compared in each group. Results. Infants ≤6 months old are less likely to fulfill KD's major diagnostic criteria within 10 days, are prone to develop incomplete KD with the lowest cholesterol level, and have the greatest chance to have CAA and the laboratory features associated with CAA, such as the longest time needed to confirm CA diagnosis, lower hemoglobin level, lower albumin level, and higher platelet count. Infants <1 year old develop higher percentage of leukocytosis and sterile pyuria. But this group has fewer patients with neck lymphadenopathy.

    2014-01-01

    Full Text Available Antiphospholipid syndrome (APS is an acquired autoimmune thrombophilia characterized by the presence of a heterogeneous family of antibodies that bind to plasma proteins with affinity for phospholipid surfaces. The two major protein targets of antiphospholipid antibodies are prothrombin and β2-glycoprotein I (β2GPI. APS leads to aprothrombotic state, and it is characterized by the occurrence of arterial, venous or microvascular thrombosis or recurrent fetal loss. The diagnosis of APS is based on a set of clinical criteria and the detection of lupus anticoagulant (LA, anticardiolipin antibodies (ACA or anti-β2GPI in plasma. Although laboratory tests are essential for APS diagnosis, these tests have limitations associated with the robustness, reproducibility and standardization. The standardization of diagnostic tests for detection of APLAs has been a challenge and a variety of results have been obtained using different commercial kits and in-house techniques. An increased sensitivity of the ELISA kits for detection of ACA effectively has contributed to APS diagnosis. However, the lack of specificity associated with a high number of false-positive results is a clinical and laboratorial challenge, since such results may lead to mistaken clinical decisions, such as prescription of oral anticoagulant, leading to the risk of hemorrhaging. Furthermore, clinicians are often unfamiliar with these tests and have difficulty interpreting them, requiring interaction between clinical and laboratory professionals in order to ensure their correct interpretation.

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

    Full Text Available Charcot-Marie-Tooth disease (CMT is the most common hereditary neuromuscular disorder. Careful assessment of clinical presentations, mode of inheritance, electrophysiological studies, and genetic analysis form the basis for the diagnosis of CMT. CMT4 is a group of progressive motor and sensory axonal demyelinating neuropathies. It is distinguished from other forms of CMT by autosomal recessive pattern of inheritance, variable clinical manifestations, electrophysiological study, nerve biopsy, and specific genetic studies. Here, we report an interesting case of hereditary neuropathy with recessive inheritance pattern who presented with combined clinical phenotypes of 4B1, 4C, and 4D subtypes. The histopathological study revealed onion bulb appearance suggestive of demyelination and remyelination phenomenon. The overlapping clinical manifestation may create a diagnostic challenge which would be confirmed by specific molecular analysis.

    Human citomegalovirus (CMV) is a beta-herpesvirus able to establish lifelong persistent infections which usually remain asymptomatic. However, severe diseases may develop in immunocompromised subjects (e.g., AIDS patients and transplant recipients) and if acquired in utero. Circulating CMV clinical strains display genetic polymorphisms in multiple genes, which may be implicated in CMV-induced immunopathogenesis, as well as strain-specific tissue-tropism, viral spread in the host cells and virulence, finally determining the wide spectrum of clinical manifestations of CMV disease. Current literature report a number of studies regarding the main CMV polymorphic genes (UL55-gB, UL144, UL73-gN, UL74-gO), their diagnostic and therapeutic impact, their potential clinical relevance as prognostic markers. This paper aims to critically analyse the results of these studies and evaluate the linkage of strain-specific genotypes with clinical manifestations of CMV disease and their perspective implications.

    Full Text Available Background: The dermatological manifestations associated with intestinal diseases are becoming more frequent, especially now when new clinical entities, such as Non-Celiac Gluten Sensitivity (NCGS, are identified. The existence of this new entity is still debated. However, many patients with diagnosed NCGS that present intestinal manifestations have skin lesions that need appropriate characterization. Methods: We involved 17 patients affected by NCGS with non-specific cutaneous manifestations who got much better after a gluten free diet. For a histopathological and immunopathological evaluation, two skin samples from each patient and their clinical data were collected. Results: The median age of the 17 enrolled patients affected by NCGS was 36 years and 76% of them were females. On the extensor surfaces of upper and lower limbs in particular, they all presented very itchy dermatological manifestations morphologically similar to eczema, psoriasis or dermatitis herpetiformis. This similarity was also confirmed histologically, but the immunopathological analysis showed the prevalence of deposits of C3 along the dermo-epidermal junction with a microgranular/granular pattern (82%. Conclusions: The exact characterization of new clinical entities such as Cutaneous Gluten Sensitivity and NCGS is an important objective both for diagnostic and therapeutic purposes, since these are patients who actually benefit from a GFD (Gluten Free Diet and who do not adopt it only for fashion.

    Nowadays, Thailand encounters a serious economic crisis. A clear consensus has been made that a cost-saving system must be the important tool. Both private and government organizations are engaged in this situation. We studied the cost-saving in the clinical laboratory. A questionnaire was distributed to 45 hospital laboratories located in Bangkok. Results showed that efforts to control the cost are the essential policy. There was a variety of factors contributing to the cost-saving process. The usage of public utility, non-recycle material and unnecessary utility were reconsidered. Besides, capital cost (wages and salary) personnel incentive are assessed. Forty three of the 45 respondents had attempted to reduce the cost via curtailing the unnecessary electricity. Eliminating the needless usage of telephone-call. water and unnecessary material was also an effective strategy. A reduction of 86.9%, 80 % and 80.0% of the mentioned factors respectively, was reported. An inventory system of the reagent, chemical and supplies was focused. Most of the laboratories have a policy on cost-saving by decreased the storage. Twenty eight of the 45 laboratories considered to purchase the cheaper with similar quality reagents instead. And some one would purchase a bulky pack when it is the best bargain. A specific system "contact reagent with a free rent instrument" has been used widely (33.3%). Finally, a new personnel management system has been chosen. Workload has rearranged and unnecessary extra-hour work was abandoned.

    As ~75% of the Werner syndrome (WS) patients recognized between 1904 and 2008 all over the world are of Japanese origin, the most case reports and clinical studies on WS has been published in Japanese journals. Thus, the detailed English-written clinical review on the recent WS case reports has been warranted. Although WS has been characterized by a variety of clinical manifestations mimicking premature aging, the recent longevity and delayed age-associated manifestations observed both from Japanese WS and general population may suggest a common environmental effect on some gene(s) other than WRN and may give us a newer pathophysiological look at WS and also natural aging through the molecular dysfunction of WRN.

    As one can see by the tests listed at www.amp.org, molecular diagnostic techniques have enabled the laboratory professionals to play an integral role in the identification and quantitation of viral infectious agents. Viral loads can be determined for HIV, HBV, and HCV using a variety of molecular methods such as real-time PCR, TMA, NASBA, and bDNA. Determining the amount of viral particles in a sample can not only monitor the status and progression of the disease, but can also guide recommendations for antiviral therapy. Other assays listed include cytomegalovirus, enterovirus, and human metapneumovirus detection, HPV testing, influenza and respiratory virus panels, and West Nile virus detection in blood donations using a variety of molecular methodologies. The use of molecular methodologies in the detection of viral pathogens has grown at an astounding rate, especially in the past two decades. It is now widely accepted that PCR is the "gold standard" for nucleic acid detection in the clinical laboratory as well as in research facilities. This article only touched on some of the common, widely used assays and platforms used in the identification process. With more and more assays being developed, the cost behind molecular testing has decreased since there are more competitors on the market. At one point, laboratorians may have thought of routine molecular testing as the wave of the future. It is obvious the future is upon us. Molecular diagnostics has become part of the daily, routine workload in most clinical laboratories. The advent of fully automated systems with faster turn around times has given laboratory professionals the tools necessary to report out accurate and sensitive results to clinicians who can ultimately improve patient care and outcomes by rendering a correct and rapid diagnosis.

    Seventy five percent or more of a diagnosis comes from a proper medical history along with an excellent physical examination. This leaves to the clinical laboratory the function of supporting the findings, determining prognosis, classifying the diseases, monitoring the diseases and, in the minimum of cases, establishing the diagnosis. In recent years there has been a global phenomenon in which the allocation of resources to health care has grown in an excessive way; the Instituto Mexicano del Seguro Social is not an exception with an increase of 29 % from 2009 to 2011; therefore, it is necessary to set containment and reduction without compromising the quality of patient care.

    The clinical picture caused by the bite of Latrodectus spp. is described, including the patient's general condition with agonizing pains, cramps, spasms, motor unrest, boardlike abdomen, "facies latrodectismica", sweating, oliguria, hypertension, anxiety, mental excitation and an extended convalescence. The notorious biters are mainly L. mactans, L. variolus, L. hesperus, L. tredecimguttatus, L. hasselti, L. indistinctus and L. menavodi, all of which appear to provoke somewhat similar clinical pictures. For some species, however, there is limited data and for the toxicity of some spiders, such as L. rhodesiensis, no data are available, However, it would appear that the clinical manifestations of the venom are similar in all species.

    Dysregulation of normal kidney functions in chronic kidney disease (CKD) leads to several pathophysiologic abnormalities that have the potential to significantly clinically affect the CKD patient. This article discusses the clinical impact of hypertension, hypokalemia, anemia, dysrexia, nausea/vomiting, and constipation in the CKD patient and therapies for these conditions. These clinical manifestations of disease may not occur in every patient and may also develop later during the progression of disease. Therefore, monitoring for, identifying, and addressing these factors is considered an important part of the medical management of CKD.

    The healthcare sector is an important contributor to mercury (Hg) pollution because of the potential presence of mercury in thermometers, blood pressure cuffs, amalgams, etc. There are also other potential sources of mercury in this sector which are used frequently and in high volumes where the presence of the metal is not obvious and which might be collectively contributing to pollution. For instance, some chemicals used for the clinical diagnosis of illness may contain mercury. The goal of this study was to investigate potential sources of mercury pollution, which originate from clinical laboratory discharges, using an exploratory approach. The focus was on the residue generated during automatic analysis of patients' bodily fluids at a medical center in Hermosillo, Sonora, Mexico. This study shows an overview of what might be happening in the region or the country related to non-obvious sources of mercury in the healthcare sector. The results showed measurable levels of mercury in the residues coming from urine sediment analysis. These amounts do not exceed the maximum allowed by Mexican environmental regulations; nevertheless, the frequency and cumulative volume of residues generated, combined with the potential for persistence and the bioaccumulation of mercury in the environment, warrant attention. The work carried out in this study is being taken as a model for future studies for pollution prevention in the healthcare sector with the goal of measuring mercury emissions to the environment from clinical laboratory wastewater, including identifying sources which--while not obvious--could be important given the frequency and volume of their use in the clinical diagnosis.

    Full Text Available The research objective was to study frequency of antenatal infection and record probable clinical manifestations in 100 children with HCMV born from mother with HCMV in blood and mononuclear cells. The study identified poly-systemic internal organ damage in neonates due to prenatal HCMV. Research procedures involved study of 100 pairs of patients, Mother-Child tandem, using regular clinical assessment methods per algorithm and HCMV diagnostic methods: ELISA, affinity and avidity of HCMV antibodies, and HCMV genome identification via PCR method in blood plasma and mononuclear cells. Initial clinical disease manifested in 71% of children during late neonatal period. Children who died of HCMV (5% were infected antenatal, and 39% were born prematurely. Embryonic stigma found in five cases. HCMV’s affinity to different tissues during the process of embryogenesis leads of poly-systemic damage and results in various clinical manifestations in the postnatal period. HCMV’s ability to invade mononuclear blood cells jeopardizes the antivirus defense system. The research is vital to deter the transmission of the virus and provide HCMV specific treatment to couples planning to have children.

    Full Text Available OBJECTIVE: To evaluate clinically, and with laboratory, tests, women with polycystic ovary syndrome (PCO. PATIENTS: One hundred and twelve women with PCO were studied. METHODS: The following data was recorded: Current age; age at menarche; menstrual irregularity, occurrence of similar cases in the family; fertility, obstetric history; body mass index (BMI; and presence of hirsutism. Serum measurements of follicle stimulating hormone (FSH, luteinizing hormone (LH, prolactin, free testosterone, and dehydroepiandrosterone sulfate were taken. RESULTS: All patients presented either oligomenorrhea (31 percent, periods of secondary amenorrhea (9 percent, or both alterations (60 percent. The majority of the patients were infertile (75.6 percent. The LH/FSH ratio was higher than 2:1 in 55 percent of the patients and higher than 3:1 in 26.2 percent. The ultrasonographic aspect of the ovaries was considered to be normal in 31 percent. CONCLUSION: The main clinical feature of the PCO is the irregularity of menses since menarche, and that the laboratory tests would be important to exclude other disorders such as hyperprolactinemia or hyperandrogenemia caused by late-onset congenital adrenal hyperplasia.

The following criteria were assigned: A: to meet variable one and at least two of the other seven variables and B: to meet at least four of the eight variables. All of the patients with preleukemia met either A or B and none of the patients with CAA or a-PNH did. Conclusions Preleukemia is different from CAA or a-PNH. It has its own clinical and laboratory features, which may be useful for its prospective diagnosis.

    The objective of this study was to analyze the clinical manifestation, imaging characteristics, genotype, and the relationship between the three aforementioned parameters in two pedigrees suffering from spinocerebellar ataxia. To evaluate the clinical manifestation of the two pedigrees and to compare the characteristics, we performed the MRI analysis of some patients from both pedigrees, while 2 ml of the peripheral blood sample was collected for gene analysis. The gene analysis data showed that pedigree 1 was certified spinocerebellar ataxia type-2 (SCA2); the CAG repeats in the proband, proband's mother, and proband's brother were 44, 36, and 38, respectively. The MRI revealed brainstem cerebellar atrophy and "cross sign" and "ordinate sign" of pons. Pedigree 2 was certified SCA1; the CAG repeats of the proband, proband's aunt, and proband's asymptomatic cousin were 60, 51, and 52, respectively. The MRI revealed cerebellar atrophy in these individuals. We, therefore, concluded that it was difficult to diagnose the SCA subset solely through the clinical manifestation. The imaging characteristics analysis and final diagnosis depended basically on gene analysis data.

    Systemic lupus erythematosus (SLE) is an autoimmune disorder with heterogeneous clinical manifestations and target tissue damage. Currently, several genes have been associated with SLE susceptibility, including vitamin D receptor (VDR), which is a mediator of immune responses through the action of vitamin D. Polymorphisms in the VDR gene can impair the vitamin D (D3) function role, and since SLE patients show deficient D3 blood levels, it leads to a possible connection to the disease's onset. In our study we searched for an association between VDR polymorphisms and risk of developing SLE, as well as the disease's clinical manifestations. We enrolled 158 SLE patients and 190 Southeast Brazilian healthy controls, genotyped for five Tag single nucleotide polymorphisms (SNPs), covering most of the VDR gene region. We found an association between VDR SNPs and SLE for the following clinical manifestations: rs11168268 and cutaneous alterations (p=0.036), rs3890733 (p=0.003) rs3890733 and arthritis (p=0.001), rs2248098 and immunological alterations (p=0.040), rs4760648 and antibody anti-dsDNA (p=0.036).

    Between 15 and 45 percent of a clinical laboratory's operating budget is spent on supplies. Given the size of this expenditure, laboratory managers must pay close attention to the supply chain and develop effective strategies to manage their inventory. Areas that need analysis include the carrying cost of supplies, the cost to generate a purchase order, methods to efficiently count supplies on hand, processes to ensure that lot number items are used before their expiration, and detailed analysis of the inventory. At the University of California-San Francisco Medical Center, we investigated options to manage our inventory and implemented a computerized system. The system required modifications to existing practices, which initially seemed unwieldy. However, after a relatively short learning curve, the improvement to operations has been significant, with a reduction in wasted reagents, fewer staff hours used to count supplies, and the ability to provide prompt analysis of the inventory for audits and discussions with administration. Focusing on the supply chain has allowed us to reduce inventory expenses by approximately 8 percent, reduce waste, given us a more focused understanding of our operations, and provided us with the ability to analyze our inventory easily.

    Full Text Available Objective: to compare the clinical manifestations of coxitis with the data of HJ ultrasound study (USS on inpatient samples.Subjects and methods. This cross-sectional study enrolled 220 AS patients meeting the modified 1984 New York criteria who had been consecutively admitted to the clinic of the V.A. Nasonova Research Institute of Rheumatology in 2012–2013. A specially designed schedule was filled out for each patient. Disease activity was measured by the BASDAI and ASDAS and functional status was assessed by the BASFI. Coxitis was diagnosed on the basis of clinical signs, such as HJ pain and/or movement limitations on patient admission to the clinic. All the patients underwent HJ USS.Results. The clinical signs of coxitis were found in 162 (73.6% patients. In 107 (66% of them, pain intensity recorded by the digital rating scale if only in one joint was 4 scores or higher. The patients with and without the clinical signs of coxitis were matched for age and disease duration. However, in coxitis, high disease activity was detected significantly more frequently and BASFI scores were also significantly higher. USS indicated that 119 (54% patients had joint effusion. HJ effusion was found in 104 (63% of the 162 patients with clinically manifest coxitis; and among the119 patients with USS verified coxitis, 87% were seen to have clinical signs of joint injury and 104 (47% patients had both clinical and ultrasound signs of HJ injury simultaneously. USS revealed no signs of synovitis in 58 patients with the clinical signs of HJ lesion.Conclusion. Among the patients with AS, the rate of coxitis runs to 51%. The patients with coxitis have higher disease activity and more pronounced functional impairments than those without HJ injury. Coxitis causes considerably diminished working ability. In a number of cases, USS allows, when the clinical manifestations are similar, a differential diagnosis between synovitis and enthesitis located in this

    Full Text Available Background: Computed tomography (CT used in pediatric pediatrics brain injury (TBI to ascertain neurological manifestations. Nevertheless, this practice is associated with adverse effects. Reports in the literature suggest incidents of morbidity and mortality in children due to exposure to radiation. Hence, it is found imperative to search for a reliable alternative. Objectives: The aim of this study is to find a reliable clinical alternative to detect an intracranial injury without resorting to the CT. Materials and Methods: Retrospective cross-sectional study was undertaken in patients (1-14 years with blunt head injury and having a Glasgow Coma Scale (GCS of 13-15 who had CT performed on them. Using statistical analysis, the correlation between clinical examination and positive CT manifestation is analyzed for different age-groups and various mechanisms of injury. Results: No statistically significant association between parameteres such as Loss of Consciousness, ′fall′ as mechanism of injury, motor vehicle accidents (MVA, more than two discrete episodes of vomiting and the CT finding of intracranial injury could be noted. Analyzed data have led to believe that GCS of 13 at presentation is the only important clinical predictor of intracranial injury. Conclusion: Retrospective data, small sample size and limited number of factors for assessing clinical manifestation might present constraints on the predictive rule that was derived from this review. Such limitations notwithstanding, the decision to determine which patients should undergo neuroimaging is encouraged to be based on clinical judgments. Further analysis with higher sample sizes may be required to authenticate and validate findings.

    The translational capacity of data generated in preclinical toxicological studies is contingent upon several factors, including the appropriateness of the animal model. The primary objectives of this article are: 1) to analyze the natural history of acute and delayed signs and symptoms that develop following an acute exposure of humans to organophosphorus (OP) compounds, with an emphasis on nerve agents; 2) to identify animal models of the clinical manifestations of human exposure to OPs; and 3) to review the mechanisms that contribute to the immediate and delayed OP neurotoxicity. As discussed in this study, clinical manifestations of an acute exposure of humans to OP compounds can be faithfully reproduced in rodents and nonhuman primates. These manifestations include an acute cholinergic crisis in addition to signs of neurotoxicity that develop long after the OP exposure, particularly chronic neurologic deficits consisting of anxiety-related behavior and cognitive deficits, structural brain damage, and increased slow electroencephalographic frequencies. Because guinea pigs and nonhuman primates, like humans, have low levels of circulating carboxylesterases-the enzymes that metabolize and inactivate OP compounds-they stand out as appropriate animal models for studies of OP intoxication. These are critical points for the development of safe and effective therapeutic interventions against OP poisoning because approval of such therapies by the Food and Drug Administration is likely to rely on the Animal Efficacy Rule, which allows exclusive use of animal data as evidence of the effectiveness of a drug against pathologic conditions that cannot be ethically or feasibly tested in humans.

    Riba, Jordi; Barbanoj, Manel J

    2005-06-01

    Since the winter of 1999, the authors and their research team have been conducting clinical studies involving the administration of ayahuasca to healthy volunteers. The rationale for conducting this kind of research is twofold. First, the growing interest of many individuals for traditional indigenous practices involving the ingestion of natural psychotropic drugs such as ayahuasca demands the systematic study of their pharmacological profiles in the target species, i.e., human beings. The complex nature of ayahuasca brews combining a large number of pharmacologically active compounds requires that research be carried out to establish the safety and overall pharmacological profile of these products. Second, the authors believe that the study of psychedelics in general calls for renewed attention. Although the molecular and electrophysiological level effects of these drugs are relatively well characterized, current knowledge of the mechanisms by which these compounds modify the higher order cognitive processes in the way they do is still incomplete, to say the least. The present article describes the development of the research effort carried out at the Autonomous University of Barcelona, commenting on several methodological aspects and reviewing the basic clinical findings. It also describes the research currently underway in our laboratory, and briefly comments on two new studies we plan to undertake in order to further our knowledge of the pharmacology of ayahuasca.

    Full Text Available Background: India is one of the seven identified Southeast Asian countries reporting frequent outbreaks of dengue fever (DF. Aims: This study was to analyze clinical and laboratory profile and predictive markers of thrombocytopenia and length of hospital stay in DF. Materials and Methods: This record-based retrospective study conducted in a coastal district of Karnataka, South India, included all dengue cases in adults aged >18 years, admitted during period of January 2011 to December 2014. Multivariate logistic regression analysis was carried out to compute odds ratio (OR and 95% confidence interval (CI to assess independent associations of variables with low platelet count and longer duration of hospital stay. Results: Among 207 dengue immunoglobulin M (IgM antibody confirmed cases (mean age of 36.94 ± 14.61 years, 143 (69.1% were males and 64 were females. The mean duration of illness and hospital stay were 4.94 ± 3.58 days and 5.98 ± 2.58 days, respectively.

    2014-05-01

    The article considers the principles of modern classification of hypersensitivity, pathogenic mechanisms of formation of its various types resulting in development of typical clinical symptoms and syndromes. The knowledge and comprehension of these issues is important for physicians of different specializations since it permits to properly make out and formulate diagnosis and timely send patient for examination and treatment to such specialist as allergist-immunologist. The particular attention was paid to description of pathogenesis of diseases and syndromes underlaid by IgE-mediated type of hypersensitivity since their share is highest and clinical manifestations frequently require emergency medical care. The diagnostic of allergic diseases is to be implemented sequentially (step-by-step) and include common clinical and special (specific) methods. In case of choosing of extent of specialized allergological examination the diagnostic significance of techniques and their safety is to be taken into account concerning condition of patient. The diagnosis is objectively formulated only by complex of examination results. It is worth to remember about possibility of development of syndromes similar to IgE-mediated allergy by their clinical manifestations but belonging to non-allergic type of hypersensitivity. It is important to know main causes, mechanisms and ways of formation of such reactions previously named as anaphylactoid ones.

    To gain better understanding of systemic lupus erythematosus (SLE) in Dubai we studied the clinical and immunological manifestations in a cohort of 151 patients attended Rheumatology Clinic in Dubai Hospital between January 2002 and January 2007. We found that the female to male ratio was 20.5:1, with a mean age of 35.5 years (0.9). The mean age at disease onset was 28.9 years (0.8) and mean disease duration 6.7 years (0.4). Five-year survival rate in our cohort was 94%. The commonest clinical manifestations in this cohort were arthritis (88%), haematological abnormalities (61.6%), and malar rash (60.3%). Leucopenia, fever, hair loss and proteinuria were observed in approximately half of the patients. Anaemia was found in 44.3% but only 9.9% had haemolytic anaemia. Photosensitive rash was seen in 43% of patients. Approximately one-third of the patients had serositis and mouth ulcers, 30.5 and 27.2% respectively. Vasculitis was observed in 19.2% of patients. Neuropsychiatric manifestations (15.9%), discoid lupus lesions (12.6%), and brain infarcts (13.2%) were infrequent. Subacute cutaneous lupus (6%) was also uncommon. Anti-nuclear antibodies were detected in 98%, anti-double stranded DNA antibodies in 88.7%, anti-Sm antibodies in 19.7%, anti-RNP in 40.4%, anti-Ro antibodies in 52.3% and anti-La antibodies in 19.8%. Anti-cardiolipin IgM and IgG were detected in 25.3 and 22.4%, respectively. This study suggests that Arabs with SLE residing in Dubai have comparable clinical features to their counterparts in other Arab countries and Western countries. The high prevalence of positive anti-Ro antibodies among our Arab patients probably reflects a character, that is, commonly seen in SLE patients of Middle East origin.

    Full Text Available OBJECTIVE: Malarial infection is a major health problem in many parts of India. Several factors have been attributed to increased morbidity and mortality in malaria with altered hematological and hepatic parameters playing an important role. Our aim is to study the clinical, hematological and hepatic manifestations in patients with falciparum malaria. METHODS: This observational study was conducted from November 2012 to October 2013 at Kempegowda Institute of Medical Science and Research Hospital Bangalore. 75 patients of falciparum malaria confirmed by PS, MPQBC positive for Plasmodium falciparum or both falciparum and vivax were included in the study. All patients underwent detailed clinical history, thorough physical examination and investigated with hematological and hepatic parameters. This was followed by monitoring the outcome of the patients with respect to morbidity and mortality. Data was analyzed with descriptive statistical tools. RESULT: Of the 75 patients fever was present in all cases. Pallor (62% was the most common sign followed by splenomegaly (58% and icterus (48%. Anemia (60% was the most common complication, followed by jaundice (44%, cerebral malaria (40%, ARF (25%, ARDS (12%. 12 patients had severe anemia (Hb% <6 gm %. Severe thrombocytopenia (<50, 000 mm3 was seen in 5% of the patients. PT and APTT were increased in 23% and 12% of the cases respectively. 2 patients in the study expired. CONCLUSION: Clinical manifestations of plasmodium falciparum infection ranged from only fever to severe complications including cerebral malaria, acute renal failure, acute hemolytic crisis and hepatic dysfunction. Acute onset fever and splenomegaly were most common clinical manifestations found. Severe Anemia and jaundice are poor prognostic factor and has adverse outcome. Thrombocytopenia increased PT; aPTT does not have any correlation to mortality

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

    The aim of this study was to assess the orofacial manifestations and their influence on oral function in human immunodeficiency virus (HIV) positive children attending Mildmay Clinic in Uganda. This was a cross-sectional study based on clinical examination, medical records and a structured questionnaire of 368 children aged between 1.5 and 17 years. The clinical examination for dental caries was based on decayed, extracted and filled teeth (deft) and decayed, missing and filled teeth (DMFT) indices as defined by World Health Organisation. The soft tissue orofacial lesions were assessed using the classification and diagnostic criteria as described by the Collaborative Workgroup on the Oral Manifestations of Pediatric HIV Infections. Approximately 67.4% of the children were on highly active antiretroviral therapy (HAART). The majority (77.4%) of the children had at least one orofacial lesion associated with HIV, pseudomembranous candidiasis being the most prevalent. Overall, 61.7% of the children with orofacial lesions reported at least one form of discomfort in the mouth. Discomfort was particularly associated with swallowing. The prevalence of orofacial lesions was significantly higher in children with poor oral hygiene and lower in those on HAART than in their respective counterparts. The CD4+ cell count, age and gender of the children did not significantly influence the distribution of orofacial lesions. The mean deft and DMFT scores were 11.8 and 2.7, respectively. The d- and D-components contributed 54.7 and 42.1%, respectively. Consumption of sugary snacks was directly associated with dental caries. Despite these children attending an HIV care centre of excellence, they have a high prevalence of orofacial manifestations associated with HIV. The majority of the children experienced discomfort in the oral cavity, particularly during swallowing.

    Uruguay, with a total population of 3,345,000 inhabitants, is the Latin American country with the second highest number of renal replacement therapies. Long-term immunosuppressant therapy is essential for graft survival but results in reduced immunosurveillance, leading to an increased risk of complications. A variety of dermatological manifestations and a large increase in nonmelanoma skin cancers have been reported in this population. The purpose of this study was to evaluate the frequency and clinical spectrum of cutaneous manifestations in renal and renopancreatic recipients in 2 reference centers in Uruguay. Two hundred and six renal or renopancreatic recipients between 21 and 77 years old were evaluated between September 2009 and September 2011. A total of 206 dermatoses were observed; 60% of the patients had at least 1 cutaneous manifestation. The most frequent dermatoses were cutaneous side effects due to immunosuppressive treatment (40.6%), followed by infections (26.1%), miscellaneous causes (18.9%), and malignant and premalignant lesions (14.4%). Transplant recipients represent a high-risk dermatological population. Physicians in transplant units should be aware of the importance of dermatological screening in order to promote early detection of skin cancer.

    Hepatitis C Virus is associated with a wide series of extrahepatic manifestations. Based on available data the link between the virus and some of these extrahepatic diseases is only suggested and needs further confirmation. Hepatitis C Virus-related lymphoproliferative disorders, whose prototype is mixed cryoglobulinaemia, represent the most closely related extrahepatic manifestations of Hepatitis C Virus. Other Hepatitis C Virus-associated disorders include nephropathies, thyreopathies, sicca syndrome, idiopathic pulmonary fibrosis, porphyria cutanea tarda, lichen planus, diabetes, chronic polyarthritis, cardiopathy and atherosclerosis. A pathogenetic link between Hepatitis C Virus and some extrahepatic manifestations was confirmed by their responsiveness to antiviral therapy, which is now deemed the first therapeutic option to consider. By contrast, there are diseases where treatment with interferon was ineffective or dangerous. The aim of the present paper is to outline the most recent evidence concerning extrahepatic disorders that are possibly associated with Hepatitis C Virus infection. Special emphasis will be given to discussion of the most appropriate clinical approaches to be adopted in order to diagnose, treat (possibly prevent) and follow-up extrahepathic diseases in patients with Hepatitis C Virus infection.

    Objective To characterize the differences between clinical manifestations in immunocompromised patients (ICPs) and non-immunocompromised patients (non-ICPs) with tuberculosis.Methods Underlying diseases, clinical presentations, misdiagnosis, treatment and prognosis, etc, were analyzed retrospectively in 115 tuberculosis patients, including 39 ICPs and 76 non-ICPs.Results Compared with non-ICPs, the individuals who were ICP had more expectoration (64.1% vs 35.5%), pulmonary moist rale (41.0% vs 9.2%), miliary pulmonary tuberculosis (30.8% vs 2.6%), pleural effusion (48.7% vs 25.0%) and lymphadenopathy (18.0% vs 4.0 %). ICPs had less lung cavity (15.4% vs 22.4%) and pleural thickening (15.4% vs 23.7%) compared to non-ICPs. Pulmonary tuberculosis in ICPs was prone to be misdiagnosed as pneumonia (23.1% vs 6.6%). Pulmonary tuberculosis was found in the apicoposterior segment (SI+SII) in more cases in non-ICPs (21.7%, 10/46) than ICPs (10.3%, 3/29). The diagnostic value of tuberculin skin test and adenosine deaminase in pleural effusions was limited in ICPs. ICPs had significantly poorer prognoses than non-ICPs.Conclusion The clinical manifestations of ICPs with tuberculosis are atypical, misdiagnosis often occurs, resulting in a worse prognosis.

    Full Text Available OBJECTIVE: To determine the frequency and clinical manifestations of patients with post-poliomyelitis syndrome (PPS in a Brazilian division of neuromuscular disorders. METHODS: A total of 167 patients with prior history of paralytic poliomyelitis was investigated for PPS, based on international diagnostic criteria. Other variables analyzed were: gender, race, age at poliomyelitis infection, age at PPS onset, and PPS symptoms. RESULTS: One hundred and twenty-nine patients presented PPS, corresponding to 77.2% of the studied population. 62.8% were women and 37.2% were men. Mean age of patients with PPS at onset of PPS symptoms was 39.9±9.69 years. Their main clinical manifestations were: new weakness in the previously affected limbs (69% and in the apparently not affected limbs (31%; joint pain (79.8%; fatigue (77.5%; muscle pain (76%; and cold intolerance (69.8%. CONCLUSIONS: Most patients of our sample presented PPS. In Brazil, PPS frequency and clinical features are quite similar to those of other countries.

All the patients had typical clinical manifestation of MG and positive neostigmine test. All the patients knew and agreed the laboratory examinations. There were 22 males and 27 females of 2-69 years old. Chest MRI or CT scan were performed to reveal thymus gland abnormality. According to whether there was tumor in superior mediastinum, all patients were divided into 2 groups, abnormal and normal groups. Normal thymus gland group (n=30) contained 16 males and 14 famales of 6-43 years old. Abnormal thymus gland group (n=19) contained 6 male and 13 female of 2-69years old.METHODS: ① All patients were questioned about initial symptoms. Meanwhile, main clinical manifestations were recorded at hospital admission. ② 7180A automatic biochemical analyzer and automatic microplate reader were used in detecting seroimmunity index. The levels of C3, C4, IgG, IgA, IgM and CH50 in blood serum were analyzed by nephelometry. ③ Clinical classification is based on modified Osserman classification. The patients with MG were divided into six types: Ⅰ (Ocular myasthenia), Ⅱ a (Mild generalized myasthenia), Ⅱ b (Moderately severe generalized myasthenia), Ⅲ (Acute fulminating myasthenia), Ⅳ (Late severe myasthenia).MAIN OUTCOME MEASURES: ① Differences of initial symptoms and clinical manifestation of two group patients.

    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

    The harsh life in the ghettos were characterized by overcrowding, shortage of supplies (e.g. money, sanitation, medications), poor personal hygiene, inclement weather and exhaustion. Under these conditions, morbidity was mainly due to infectious diseases, both endemic and epidemic outbreaks with a high mortality rate. The dominant feature was hunger. Daily caloric allowance was 300-800, and in extreme cases (i.e. Warsaw ghetto) it was only 200 calories. The food was lacking important nutrients (e.g. vitamins, trace elements) leading to protean clinical expression, starvation and death. The clinical manifestations of starvation were referred to as "the Hunger Disease", which became the subject of research by the medical doctors in the ghettos, mainly in the Warsaw ghetto in which a thorough documentation and research were performed. The first victims of hunger were children. First they failed to thrive physically and later mentally. Like their elders, they lost weight, but later growth stopped and their developmental milestones were lost with the loss of curiosity and motivation to play. The mortality rate among babies and infants was 100%, as was described by the ghetto doctors: "when the elder children got sick, the small ones were already dead...". In the last weeks of the ghettos there were no children seen in the streets. In this article the environmental conditions and daily life of children in the ghettos are reviewed, and the manifestations of "Hunger Disease" among them is scrutinized.

    2012-01-01

    Objective: Diabetes is associated with pulmonary tuberculosis (TB), possibly due to impaired immunity, and diabetes may exacerbate the clinical manifestations of TB. Our aim was to assess the role of diabetes in the clinical manifestations of TB. Methods: We studied 1250 patients with pulmonary TB...... in an urban population in a cross-sectional study in Tanzania. All participants were tested for diabetes and HIV co-infection, and TB culture intensity was assessed. Levels of white blood cells, haemoglobin, acute phase reactants, CD4 count and HIV viral load were measured, and a qualitative morbidity...... questionnaire was used to identify the prevalence of disease-related symptoms. Results: Tuberculosis patients with diabetes had a higher neutrophil count (B 0.5 x 10 9 cells/ l, 95% CI 0.2; 0.9, P = 0.001) than non-diabetic TB patients. Serum C-reactive protein (B 18.8 mg / l, CI 95% 8.2; 29.4, P = 0...

  1. The hyperimmunoglobulin E syndrome - clinical manifestation diversity in primary immune deficiency

    Directory of Open Access Journals (Sweden)

    Szczawinska-Poplonyk Aleksandra

    2011-11-01

    Full Text Available Abstract The hyper-IgE syndromes are rare, complex primary immunodeficiencies characterized by clinical manifestation diversity, by particular susceptibility to staphylococcal and mycotic infections as well as by a heterogeneous genetic origin. Two distinct entities - the classical hyper-IgE syndrome which is inherited in an autosomal dominant pattern and the autosomal recessive hyper-IgE syndrome have been recognized. The autosomal dominant hyper-IgE syndrome is associated with a cluster of facial, dental, skeletal, and connective tissue abnormalities which are not observable in the recessive type. In the majority of affected patients with autosomal dominant hyper-IgE syndrome a mutation in the signal transducer and the activator of the transcription 3 gene has been identified, leading to an impaired Th17 cells differentiation and to a downregulation of an antimicrobial response. A mutation in the dedicator of the cytokinesis 8 gene has been identified as the cause of many cases with autosomal recessive hyper-IgE syndrome and, in one patient, a mutation in tyrosine kinase 2 gene has been demonstrated. In this paper, the authors provide a review of the clinical manifestations in the hyper-IgE syndromes with particular emphasis on the diversity of their phenotypic expression and present current diagnostic guidelines for these diseases.

    Background: Intramuscular manifestations of malignant immuno proliferative diseases (IMMID) are very rare. Purpose: To determine the prevalence and the clinical features of IMMID in a large series of patients, and to analyze their radiological appearances. Material and Methods: Between 1997 and 2007, 20 patients with IMMID (non-Hodgkin lymphoma [NHL], n=14, and myeloma, n=6) were identified. All patients underwent computed tomography (CT). In five cases, magnetic resonance imaging (MRI) was additionally performed. Results: Clinically, 16 patients presented with local pain and soft-tissue swelling. In four patients, IMMID was found incidentally. The most common site was the erector spinae muscle, followed by the iliopsoas and pelvic muscles. In 13 cases of IMMID, diffuse mass-forming muscle infiltration was found. Focal intramuscular masses were identified in seven cases. Conclusion: NHL mostly manifests as diffuse muscle enlargement, whereas myelomas form focal intramuscular masses. Nevertheless, CT and MR appearances are nonspecific and can be misinterpreted as muscle sarcoma or inflammatory disease. Although rare, muscle involvement should be considered in the differential diagnosis of muscle disorders in patients with non-Hodgkin lymphoma and myeloma

    The objective of the study is to establish the prevalence of oral manifestations and their influence on oral functions. A total of 514 subjects aged 18 to 58 years (mean 42 years) were randomly recruited from five The AIDS Support Organization (TASO) clinics in Uganda. They were clinically examined for oral lesions under field conditions by four trained dentists based on World Health Organization criteria. Women constituted 74.5% of the study population. Oral manifestations were recorded in 72% of the subjects, out of which 70% had candidiasis of pseudomembranous, erythematous, and angular cheilitis variants. Non-Hodgkin's lymphoma, atypical ulcers, necrotizing periodontitis, and hairy leucoplakia were least frequently observed in the subjects. Of those who had oral lesions (n = 370), 68.4% had some form of discomfort in the mouth. Tooth brushing, chewing, and swallowing were frequently associated with discomfort. Reported forms of discomfort were dry mouth, increased salivation, and burning sensation especially on taking salty and spicy foods or acidic drinks. Only 8.5% (n = 44) of the subjects were taking medications specifically for oral lesions, which included antifungal, antiviral, and antibacterial agents. None of the subjects were on antiretroviral therapy. Oral lesions associated with human immunodeficiency virus/acquired immunodeficiency syndrome in TASO clients is a major public health problem requiring education in recognition and appropriate management.

  4. Laboratory aspects of clinically significant rapidly growing mycobacteria

    Directory of Open Access Journals (Sweden)

    R Set

    2011-01-01

    Full Text Available The pathogenic potential of the rapidly growing mycobacteria (RGM has started being recognized. This is due to more sensitive and specific techniques in the laboratory. The RGM are generally defined as nontuberculous species of mycobacteria that show visible growth on agar media within 7 days. RGM are widely distributed in nature and have been isolated from natural water, tap water, and soil. Several biochemical tests, high performance liquid chromatography, and molecular techniques have been developed for rapid identification of these species. The American Thoracic Society and the Infectious Disease Society of America recommend that RGM should be identified to the species level using a recognized acceptable methodology such as polymerase chain reaction restriction enzyme analysis or biochemical testing and routine susceptibility testing of RGM should include amikacin, imipenem, doxycycline, the fluorinated quinolones, a sulphonamide or trimethoprim-sulphamethoxazole, cefoxitin, clarithromycin, linezolid, and tobramycin. The diseases caused by these organisms have varied manifestations. They have been responsible for a number of healthcare-associated outbreaks and pseudo-outbreaks. For recognition of outbreaks, it is important to be familiar with the causative organisms like RGM which are most frequently involved in healthcare-associated outbreaks and pseudo outbreaks. It is essential to intervene as soon as possible to interrupt this transmission. Large gaps still exist in our knowledge of RGM. Unquestionably more studies are required. Through this review, we wish to emphasize that reporting of RGM from clinical settings along with their sensitivity patterns is an absolute need of the hour.

    A retrospective analysis of three cases of clinical manifestations of migraine-like headache, including clinical features, imaging findings, and follow-up results was done to explore the potential correlation between migraine and unruptured aneurysm. Clinical data and digital subtraction angiography (DSA) results were retrospectively analyzed. All three patients met the diagnostic criteria for migraine without aura stated in the second edition of the International Classification of Headache Disorders, established by the International Headache Society in 2004. The DSA results suggested that the aneurysms occurred in the anterior communicating artery (two cases) and in the internal carotid artery (one case); the migraine attacks disappeared after aneurysm embolization, with a follow-up time of 6, 10, and 16 months in the three cases, respectively. The pathogenesis of migraine is not fully understood; however, the potential correlation between migraine attack and unruptured saccular aneurysm needs attention, and the specific pathogenesis should be further investigated.

    Full Text Available Manifestation of chorea in patients with systemic lupus erythematosus (SLE and antiphospholipid antibody syndrome (APA synd. is not common. Moreover, primary presentation of the disease with chorea is rare and only few such cases are reported in literature in recent years. We report here the case of a 28 year old woman who was first seen at the age of 10 with clinical manifestations of chorea. Later she developed deep vein thrombosis, thrombocytpenia, stroke, cardiac valve involvement and recurrent abortions. Laboratory investigations confirmed the diagnosis of SLE and the presence of antiphospholipid antibodies. We present this patient as a case of SLE and antiphospholipid antibody syndrome with chorea being her primary clinical presentation

    Full Text Available Fifty six episodes of DKA occurred in 33 patients during the period between 1998 -96. These patients were admitted and treated in Bahrami children hospital, a Tehran University teaching medical center. The most frequent clinical manifestations consisted of polyuria and polydipsia (66%, nausea and vomiting (64%, reduction in consciousness (53%, and Kussmaul respiration (53.5%. 54.6% of DKA episodes showed a pH below 7.1. There was a relationship between the severity of acidosis and the time needed for its correction. Complications during treatment appeared in 47.5% of DKA attacks, hypokalemia (18.8%, hyperkalemia (16% , hypoglycemia (10% were the most common. No brain edema or death occurred in our patients. The most common precipitating factors of DKA include unavailability of insulin or syringes (39.4%, infections (32%, and unknown causes (28.6%. The patients were divided in two different groups. The first group experienced 31 episodes of DKA in known patients suffering from diabetes mellitus and receiving insulin treatment. 25 episodes of DKA occurred in the second group with no previous history of diabetes; of interest is the finding that in 75% of recurrent attacks in group 1, the unavailability of insulin or syringes was the precipitating factor. The clinical, laboratory and complications of these two groups of patients were studied and the results obtained were compared with similar studies in other countries.

    2007-08-01

    Full Text Available Abstract Background Reports in the literature suggest that the season of birth might constitute a risk factor for the development of a major psychiatric disorder, possibly because of the effect environmental factors have during the second trimester of gestation. The aim of the current paper was to study the possible relationship of the season of birth and current clinical symptoms in unipolar major depression. Methods The study sample included 45 DSM-IV major depressive patients and 90 matched controls. The SCAN v. 2.0, Hamilton Depression Rating Scale (HDRS and Hamilton Anxiety Scale (HAS were used to assess symptomatology, and the 1 mg Dexamethasone Suppression Test (DST was used to subcategorize patients. Results Depressed patients as a whole did not show differences in birth season from controls. However, those patients born during the spring manifested higher HDRS while those born during the summer manifested the lowest HAS scores. DST non-suppressors were almost exclusively (90% likely to be born during autumn and winter. No effect from the season of birth was found concerning the current severity of suicidal ideation or attempts. Discussion The current study is the first in this area of research using modern and rigid diagnostic methodology and a biological marker (DST to categorize patients. Its disadvantages are the lack of data concerning DST in controls and a relatively small size of patient sample. The results confirm the effect of seasonality of birth on patients suffering from specific types of depression.

    Objective. To determine the clinical manifestations associated with overweight/obesity in Hispanics from Puerto Rico with fibromyalgia syndrome (FMS). Methods. A cross-sectional study was performed in 144 patients with FMS (per American College of Rheumatology (ACR) classification criteria). Sociodemographic features, FMS-related symptoms, tender points (per ACR criteria), comorbidities, and FMS treatment were examined. BMI was calculated and patients were grouped into two categories: BMI ≤ 24.9 kg/m2 (nonoverweight/obese) and BMI ≥ 25 kg/m2 (overweight/obese). Bivariate and multivariate analyses were used to evaluate differences between the study groups. Results. The mean (standard deviation (SD)) age of patients was 50.2 (9.9) years; 95.1% were females and 75.7% were overweight/obese. In the bivariate analysis, overweight/obese patients were more likely to have self-reported memory impairment, anxiety, shortness of breath, and urinary frequency than nonoverweight/obese patients. In addition, the tender point count was higher in the overweight/obese group. In the logistic regression analyses, self-reported memory impairment and urinary frequency differences remained significant after adjusting for confounding variables. Conclusion. In this population of Puerto Ricans with FMS, overweight/obese patients experienced more FMS-related manifestations than nonoverweight/obese individuals. However, prospective studies are needed to confirm these associations and to elucidate if weight reduction interventions could favorably impact the severity of FMS. PMID:26885384

    The authors elaborated data, using the retrospective method, of a group of 146 patients with affective respiratory and reflex paroxysms. They focused attention on clinical manifestations of the disease, anamnestic data suggesting possible damage or immaturity of stem structures, the influence of heredity and the family environment. They found that in 63.7% the disease was manifested before the age of 1 year, most frequently at the age of 9-12 months. The cyanotic type of paroxysms was found in 67.5% of the patients, the pallid type in 21% and 3.5% of the patients suffered from both types of paroxysms. In 27.4% perinatal risks were recorded. The influence of a family-history was statistically significant in relation to the patient's age during the first attack: in patients with a positive family-history the mean age being by 1.8 months lower. 82.9% of the patients had a normal neurological finding, the EEG was evaluated as normal in 89.6% of 125 thus examined children. Psychological examinations made in 12 children revealed in all instances anomalies of personality with a predominance of lack of compliance and adaptability to the environment. Deterioration of the health status as a result of affective respiratory and reflex paroxysms was not recorded in any of the patients.

    Croxatto, A; Prod'hom, G; Faverjon, F; Rochais, Y; Greub, G

    2016-03-01

    Automation was introduced many years ago in several diagnostic disciplines such as chemistry, haematology and molecular biology. The first laboratory automation system for clinical bacteriology was released in 2006, and it rapidly proved its value by increasing productivity, allowing a continuous increase in sample volumes despite limited budgets and personnel shortages. Today, two major manufacturers, BD Kiestra and Copan, are commercializing partial or complete laboratory automation systems for bacteriology. The laboratory automation systems are rapidly evolving to provide improved hardware and software solutions to optimize laboratory efficiency. However, the complex parameters of the laboratory and automation systems must be considered to determine the best system for each given laboratory. We address several topics on laboratory automation that may help clinical bacteriologists to understand the particularities and operative modalities of the different systems. We present (a) a comparison of the engineering and technical features of the various elements composing the two different automated systems currently available, (b) the system workflows of partial and complete laboratory automation, which define the basis for laboratory reorganization required to optimize system efficiency, (c) the concept of digital imaging and telebacteriology, (d) the connectivity of laboratory automation to the laboratory information system, (e) the general advantages and disadvantages as well as the expected impacts provided by laboratory automation and (f) the laboratory data required to conduct a workflow assessment to determine the best configuration of an automated system for the laboratory activities and specificities.

    2011-05-01

    This paper discusses a knowledge management system for clinical laboratories. In the clinical laboratory of Toranomon Hospital, we receive about 20 questions relevant to laboratory tests per day from medical doctors or co-medical staff. These questions mostly involve the essence to appropriately accomplish laboratory tests. We have to answer them carefully and suitably because an incorrect answer may cause a medical accident. Up to now, no method has been in place to achieve a rapid response and standardized answers. For this reason, the laboratory staff have responded to various questions based on their individual knowledge. We began to develop a knowledge management system to promote the knowledge of staff working for the laboratory. This system is a type of knowledge base for assisting the work, such as inquiry management, laboratory consultation, process management, and clinical support. It consists of several functions: guiding laboratory test information, managing inquiries from medical staff, reporting results of patient consultation, distributing laboratory staffs notes, and recording guidelines for laboratory medicine. The laboratory test information guide has 2,000 records of medical test information registered in the database with flexible retrieval. The inquiry management tool provides a methos to record all questions, answer easily, and retrieve cases. It helps staff to respond appropriately in a short period of time. The consulting report system treats patients' claims regarding medical tests. The laboratory staffs notes enter a file management system so they can be accessed to aid in clinical support. Knowledge sharing using this function can achieve the transition from individual to organizational learning. Storing guidelines for laboratory medicine will support EBM. Finally, it is expected that this system will support intellectual activity concerning laboratory work and contribute to the practice of knowledge management for clinical work support.

    Full Text Available Abstract Clostridium difficile is the leading cause of infectious diarrhoea in hospitalized patients. The aim of this study was to determine the risk factors important for the development of hospital-acquired Clostridium difficile-associated disease and clinical manifestations of Clostridium difficile-associated disease. The clinical trial group included 37 hospitalized patients who were selected according to the inclusion criteria. A control group of 74 hospitalized patients was individually matched with cases based on hospital, age (within 4 years, sex and month of admission.Clostridium difficile-associated disease most commonly manifested as diarrhoea (56.76% and colitis (32%, while in 8.11% of patients, it was diagnosed as pseudomembranous colitis, and in one patient, it was diagnosed as fulminant colitis. Statistically significant associations (p < 0.05 were found with the presence of chronic renal failure, chronic obstructive pulmonary disease, cerebrovascular accident (stroke and haemodialysis. In this study, it was confirmed that all the groups of antibiotics, except for tetracycline and trimethoprim-sulfamethoxazole, were statistically significant risk factors for Clostridium difficile-associated disease (p < 0.05. However, it was difficult to determine the individual role of antibiotics in the development of Clostridium difficile-associated disease. Univariate logistic regression also found that applying antibiotic therapy, the duration of antibiotic therapy, administration of two or more antibiotics to treat infections, administering laxatives and the total number of days spent in the hospital significantly affected the onset of Clostridium difficile-associated disease (p < 0.05, and associations were confirmed using the multivariate model for the application of antibiotic therapy (p = 0.001, duration of antibiotic treatment (p = 0.01, use of laxatives (p = 0.01 and total number of days spent in the hospital (p = 0.001.

    Full Text Available Background/Aim. Atopic diseases such as atopic dermatitis, allergic rhinitis and asthma have had increased prevalence during the past decade and nowadays occur in every third child in developed countries. The aim of the study was to determine frequency and type of atopic diseases at the age of two, as well as the importance the total IgE antibodies concentrations have in diagnosis and prognosis of the disease. Methods. The study involved 175 children up to two years of age. Allergy-like symptoms were found after surveying their parents and pediatric medical records. Using the fluorescence immunossay (FIA method, total IgE antibodies concentrations and specific IgE antibodies (Phadiatop infant were determined on an Immunocap 100 Dyagnostic System. Results. One or more allergy-like symptoms accounted for 57.7% of findings in children under the age of two, whilst in 19.4% the existence of IgE-related allergic diseases was found. Atopic diseases usually have clinical manifestations of atopic dermatitis (11.4%, IgE-bound wheezing/asthma (10.8% and food allergies (7.4%, and to much lesser extent those of allergic rhinitis (3.4% and urticaria (1.7%. The significantly higher total IgE antibodies concentrations were found in children with allergy-like symptoms (p < 0.0005 (cut-off 15.15 kU/L, sensitivity 76.5% specificity 71.6%. Conclusion. Almost 20% of two-year-old children have any of clinically manifested allergic diseases, with atopic dermatitis and IgE wheeze/asthma being predominant. The higher total IgE antibodies concentration is a good marker for sensitization in children with allergy-like symptoms.

    The main question in this paper was to look at the distribution of auxotypes and serovars of Neisseria gonorrhoeae and check whether they correlate with clinical symptoms/signs among female sex workers (FSW) from Kinshasa, Zaïre. The subject were 1233 FSW enrolled in a cross sectional study on STDs and HIV infection in 1988; 771 of them were followed prospectively for a median duration of 23 months. At each visit, clinical symptoms and signs of cervicitis were recorded and the subjects were screened for gonococcal and chlamydial infection. The pre-dominant auxotypes were prototrophic (35.2%), proline requiring (29.6%), and proline requiring phenylalanine inhibition (19%). Serovars 1A-6 (42.5%) and 1B-1 (16.7%) were the commonest. Infection with auxotype prototrophic and phenylalanine inhibition (Proto/Phenali) was significantly associated with both mucopurulent cervicitis and pelvic inflammatory disease; (OR = 8.9; p = 0.002 and OR =19 x9; p = 0.002; respectively). Despite the few associations found in this study, there was not clear pattern linking clinical manifestations to auxotype/serovar profiles. PMID:9582486

    In recent years, complement analysis of body fluids and biopsies, going far beyond C3 and C4, has significantly enhanced our understanding of the disease process. Such expanded complement analysis allows for a more precise differential diagnosis and for critical monitoring of complement-targeted therapy. These changes are a result of the growing understanding of the involvement of complement in a diverse set of disorders. To appreciate the importance of proper complement analysis, it is important to understand the role it plays in disease. Historically, it was the absence of complement as manifested in severe infection that was noted. Since then complement has been connected to a variety of inflammatory disorders, such as autoimmune diseases and hereditary angioedema. While the role of complement in the rejection of renal grafts has been known longer, the significant impact of complement. In certain nephropathies has now led to the reclassification of some rare kidney diseases and an increased role for complement analysis in diagnosis. Even more unexpected is that complement has also been implicated in neural, ophtalmological and dermatological disorders. With this level of involvement in some varied and impactful health issues proper complement testing is clearly important; however, analysis of the complement system varies widely among laboratories. Except for a few proteins, such as C3 and C4, there are neither well-characterized standard preparations nor calibrated assays available. This is especially true for the inter-laboratory variation of tests which assess classical, alternative, or lectin pathway function. In addition, there is a need for the standardization of the measurement of complement activation products that are so critical in determining whether clinically relevant complement activation has occurred in vivo. Finally, autoantibodies to complement proteins (e.g. anti-C1q), C3 and C4 convertases (C3 and C4 nephritic factor) or to regulatory proteins

    One important trend in the laboratory profession and quality management is the global convergence of laboratory operations. The goal of an accredited medical laboratory is to continue "offering useful laboratory service for diagnosis and treatment of the patients and also aid to the health of the nation". An accredited clinical laboratory is managed by a quality control system, it is competent technically and the laboratory service meets the needs of all its patients and physicians by taking the responsibility of all the medical tests and therapies. For this purpose, ISO 15189 international standard has been prepared by 2003. ISO 15189 standard is originated from the arrangement of ISO 17025 and ISO 9001:2000 standards. Many countries such as England, Germany, France, Canada and Australia have preferred ISO 15189 as their own laboratory accreditation programme, meeting all the requirements of their medical laboratories. The accreditation performance of a clinical microbiology laboratory is mainly based on five essential points; preanalytical, analytical, postanalytical, quality control programmes (internal, external, interlaboratory) and audits (internal, external). In this review article, general concepts on ISO 15189 accreditation standards for the clinical microbiology laboratories have been summarized and the status of a private laboratory (Acibadem LabMed, Istanbul) in Turkey has been discussed.

    Full Text Available Introduction. Hepatitis E is one of the leading clinical manifestations of acute viral hepatitis in developing countries. In industrialized countries, during the past several years, sporadic “autochthonous” cases of HEV infection have been increased. Objective. The aim of this study was to analyze the epidemiological, clinical and laboratory features of HEV infection among patients hospitalized at the Department of Infectious Diseases in Military Medical Academy, Sofia, Bulgaria. Methods. A retrospective study of 806 cases of acute viral hepatitis was performed at the Department of Infectious Diseases in Military Medical Academy, Sofia, Bulgaria, between December 2004 and September 2012. The etiological diagnosis was established by ELISA. The statistical analysis was performed using Excel 2007 (Microsoft, Redmond, Washington, USA and SPSS Statistics 19.0 (IBM Corp., Armonk, New York, USA. Results. Specific reaction to anti-HEV-IgM and anti-HEV-IgG antibodies were detected in 20 (2.48% of 806 patients. The most observed clinical presentations were jaundice (85%, fatigue (85%, anorexia (65%, abdominal discomfort (55% and fever (40%. The mean values of aspartate transaminase and alanine transaminase were 521 IU/l and 881 IU/l, respectively. The cholestasis was slight, marked with mean values of gamma-glutamyl transferase and alkaline phosphatase, respectively 418 IU/l and 486 IU/l. Conclusion. We report twenty autochthonous sporadic cases of acute infection with HEV. The zoonotic etiology of the virus as well as the foodborne transmission of the infection is discussed. We found that aging and pre-existing underlying diseases are risk factors for a severe course of the HEV infection.

    Full Text Available Autoimmune pancreatitis (AIP is a special type of chronic pancreatitis which is autoimmune mediated. The international consensus diagnostic criteria (ICDC 2011 proposed two types of AIP: type I is associated with histological pattern of lymphoplasmacytic sclerosing pancreatitis (LPSP, characterized by serum IgG4 elevation, whereas type 2 is named idiopathic duct-centric pancreatitis (IDCP, with granulocytic epithelial lesion (GEL and immunoglobulin G4 (IgG4 negative. The pathogenic mechanism is unclear now; based on genetic factors, disease specific or related antigens, innate and adaptive immunity may be involved. The most common clinical manifestations of AIP are obstructive jaundice and upper abdominal pain. The diagnosis can be made by a combination of parenchymal and ductal imaging, serum IgG4 concentrations, pancreatic histology, extrapancreatic disease, and glucocorticoid responsiveness according to ICDC 2011. Because of the clinical and imaging similarities with pancreatic cancer, general work-up should be done carefully to exclude pancreatic malignant tumor before empirical trial of glucocorticoid treatment. Glucocorticoid is the most common drug for AIP to induce remission, while there still exists controversy on steroid maintenance and treatment for relapse. Further studies should be done to identify more specific serum biomarkers for AIP, the pathogenic mechanisms, and the treatment for relapse.

    45,X/46,XY mosaicism is a rare chromosomal abnormality and probably underdiagnosed. Although clinical and genetic analyses have been performed in some disorders of sexual development, there have been few studies focusing on the phenotype and genetic details of 45,X/46,XY mosaicism, especially in the Chinese population. The aim of this study was to describe the experience of our service in relation to 16 cases with 45,X/46,XY mosaicism. The age at the first evaluation of the patients ranged from 43 days to 30 years. Eight patients were reared as female and 8 as male. The main reasons for examination were primary amenorrhea, sterility, or ambiguous genitalia. Short stature was more common in female than in male patients. Two patients accepted gonadectomy due to tumor risk and none presented gonadal malignancy. The SRY gene was amplified positively in all of the patients. AZF gene microdeletions were present in 6 of 8 male patients, and all adult male patients had no sperm. No correlation has been found between clinical manifestations and the proportion of mosaic cells in peripheral blood. Our observations may permit a better management of people with 45,X/46,XY mosaicism.

    Full Text Available Objectives. CD57 is normally found on NK-cells, but little is known about its expression in prostatic tissue. Methods. We investigated CD57 expression by immunohistochemistry using tissue microarrays containing 3262 prostate cancers (PCa, lymph node metastases, and benign prostatic tissue. The results were compared with clinical and pathological parameters. Results. Overall, 87% of PCa showed a moderate or strong expression of CD57. There was no significant difference to corresponding benign prostatic tissue. CD57 was increasingly lost from incidental over clinically manifest cancers to metastases. It correlated significantly with Gleason grade and pT-category, but not with PSA tissue expression. Loss of CD57 expression was an independent risk factor for PSA recurrence after prostatectomy in a multivariate Cox regression analysis. In standard sections, CD57 expression was heterogeneous, especially in large, high-grade PCa. Conclusions. There is a peculiar expression of CD57 in PCa and benign prostatic tissue. CD57 loss is associated with tumor dedifferentiation and tumor size. However, the use of this marker for prognostic purposes is hampered by its heterogeneous expression.

    Full Text Available A 59-year-old female patient with mitral valve prolapse and a previous history of lumbosacral spondyloarthrosis and lumbar disk hernia had an episode of infective endocarditis due to Streptococcus viridans, which evolved with peripheral embolism to the left kidney, spleen, and left iliac artery, and intraventricular cerebral hemorrhage. Her clinical manifestations were low back pain and hematuria, which were initially attributed to an osteoarticular condition. Infective endocarditis is a severe polymorphic disease with multiple clinical manifestations and it should always be included in the differential diagnosis by clinicians.

    Nipple eczema exhibits as a minor manifestation of atopic dermatitis (AD) or occurs as a single skin symptom on the nipple. To characterize the relationship between nipple eczema and AD, a clinical evaluation and an immunohistochemical study were performed. All cases of nipple eczema were confirmed histopathologically. We divided the patients with nipple eczema into 2 groups, namely, those with AD and those without AD, and compared several clinical features. Upon histological examination, the degree of inflammation was subjectively graded as mild, moderate, or severe by 2 separate investigators. Immunohistochemical stainings were performed by using antiinterleukin (IL)-4, anti-IL-13, anti-CD4, and anti-CD8 antibodies, and the results were scored semiquantitatively. In 43 cases evaluated, 12 were nipple eczema with AD. The clinical analysis and histological examination showed no significant differences between the groups. There were consistent findings of IL-4 expressions throughout the epidermis and IL-13 expression mainly in the perivascular area of the dermis. Although CD4 and CD8 were expressed in the cells in the dermis, CD8 expression was detected in the serocrusts of the epidermis. Expression levels of IL-4, IL-13, CD4, and CD8 exhibited no significant differences between the nipple eczema group with AD and the nipple eczema group without AD. Although nipple eczema may accompany AD, we found no definite differences in the degree or pattern of inflammation and cytokine expression level regardless of whether AD was present or not. Serocrust formation seemed to be mainly a collection of CD8-positive cells.

    Retention of recent graduates and other laboratory practitioners in the workplace will play a key role in addressing current and projected shortages of clinical laboratory scientists (CLS) and technicians (CLT). In addition, with overrepresentation of the aging Baby Boomer generation in laboratory supervisory and management positions, it is crucial not only to retain younger practitioners, but to prepare them for assuming these important functions in the future. Mentoring, a practice commonly employed in other professions, is widely considered to be useful in employee retention and career advancement. Mentoring has probably been used in the clinical laboratory profession, but has not been well documented. In the clinical laboratory environment, potential mentors are in the Veteran and Baby Boomer generations, and new practitioners who could benefit from mentoring are in Generation X. Generational differences among these groups may present challenges to the use of mentoring. This article will attempt to provide a better understanding of generational differences and show how mentoring can be applied in the setting of the clinical laboratory in order to increase retention and promote career advancement of younger practitioners. A panel of five laboratory managers provided examples of mentoring strategies. Definitions, benefits, and examples of mentoring are addressed in the accompanying article, "Passing the Torch: Mentoring the Next Generation of Laboratory Professionals".

    The CAP (College of American Pathologists) was established in 1962 and, at present, CAP-accredited laboratories include about 6000 institutions all over the world, mainly in the U.S. The essential purpose of CAP accreditation is high quality reservation and improvement of clinical laboratory services for patient care, and is based on seven points, listed below. (1) Establishment of a laboratory management program and laboratory techniques to assure accuracy and improve overall quality of laboratory services. (2) Maintenance and improvement of accuracy objectively by centering on a CAP survey. (3) Thoroughness in safety and health administration. (4) Reservation of the performance of laboratory services by personnel and proficiency management. (5) Provision of appropriate information to physicians, and contribution to improved quality of patient care by close communication with physicians (improvement in patient care). (6) Reduction of running costs and personnel costs based on evidence by employing the above-mentioned criteria. (7) Reduction of laboratory error. In the future, accreditation and/or certification by organizations such as CAP, ISO, etc., may become a requirement for providing any clinical laboratory services in Japan. Taking the essence of the CAP and the characteristics of the new international standard, ISO151589, into consideration, it is important to choose the best suited accreditation and/or certification depending of the purpose of clinical laboratory.

    Full Text Available Objective : To determine predictive factors, clinical and demographics characteristics of patients with pulmonary embolism (PE in ICU, and to identify factors associated with poor outcome in the hospital and in the ICU. Methods : During a four-year prospective study, a medical committee of six ICU physicians prospectively examined all available data for each patient in order to classify patients according to the level of clinical suspicion of pulmonary thromboembolism. During the study periods, all patients admitted to our ICU were classified into four groups. The first group includes all patients with confirmed PE; the second group includes some patients without clinical manifestations of PE; the third group includes patients with suspected and not confirmed PE and the fourth group includes all patients with only deep vein thromboses (DVTs without suspicion of PE. The diagnosis of PE was confirmed either by a high-probability ventilation/perfusion (V/Q scan or by a spiral computed tomography (CT scan showing one or more filling defects in the pulmonary artery or in its branches. The diagnosis was also confirmed by echocardiography when a thrombus in the pulmonary artery was observed. Results : During the study periods, 4408 patients were admitted in our ICU. The diagnosis of PE was confirmed in 87 patients (1.9%. The mean delay of development of PE was 7.8 ± 9.5 days. On the day of PE diagnosis, clinical examination showed that 50 patients (57.5% were hypotensive, 63 (72.4% have SIRS, 15 (17.2% have clinical manifestations of DVT and 71 (81.6% have respiratory distress requiring mechanical ventilation.

    Hand, foot, and mouth disease (HFMD), with vesiculae on the hands, feet and mouth, is an infectious disease caused by many viral pathogens. However, the differences of immune response induced by these pathogens are unclear. We compared the clinical manifestations and the levels of immunologic indicators from 60 HFMD patients caused by different viral pathogens to analyze the differences in the immune response. It was shown that Th2 cytokines (IL-4 and IL-10) increased significantly in EV71-infected children; Th1 cytokines (IL-2 and IFN-γ) rose in CA16-infected children; both Th1 and Th2 cytokines elevated in non-EVG-infected children; only individual cytokines (such as IL-10) went up in EVG-infected children. Meanwhile, the antibodies induced by viral infection could not cross-interfere between the different pathogens. These differences might be due to variations in the immune response induced by the individual pathogens or to the pathogenesis of the infections by the individual pathogens. PMID:27336013

    The food-borne trematodiases are an important group of neglected tropical diseases (NTDs). Over 40 million people are infected with food-borne trematodes and 750 million (>10% of the world's population) are at risk of these NTDs. Here, we review the life cycles, epidemiology, clinical manifestations, pathology and pathogenesis, diagnosis, treatment, and prevention and control of the major food-borne trematodiases in Southeast Asia. We focus particularly on opisthorchiasis caused by Opisthorchis viverrini and clonorchiasis caused by Clonorchis sinensis, which people contract by ingestion of metacercariae in flesh of raw or undercooked freshwater fishes, on fascioliasis caused by Fasciola species, where infection arises from ingestion of metacercariae on water plants such as watercress, and on Paragonimus species, the lung flukes, which use freshwater crabs and other crustaceans as intermediate hosts. We also include information on the intestinal flukes Fasciolopsis buski, the echinostomes and the so-called 'minute intestinal flukes' of the family Heterophyidae. Ecological information, placing emphasis on reservoir hosts, intermediate snail hosts and secondary hosts where applicable, is also reviewed and research needs are highlighted.

    Purpose To review the current progress in epidemiology, etiology, clinical manifestation, and pathophysiology of severe cutaneous adverse drug reactions(SCADRs). Data sources Data were acquired by using Blackwell-Synergy, PubMed, original articles published in the main Chinese journals and related medical textbooks materials. Study-selection and date extraction Throughout the literature review 49 articles were selected. Results SCADRs cases are rare, however, the implication is life threatening with significant mortatity rates. Epidemiology studies have shown various incidences from different regions, gender, age, race and concurrent illness. There are typical signs and symptoms for each type of SCADRs, but this is not always so. Drugs associated with inducing SCADRs are anticonvulsants, antibiotics, NSAIDs and antirheumatic drugs. In some countries, especially in Asia, traditional drugs are offen the cause of SCADRs. Genetic polymorphisms and viral infections are predisposition factors of SCADRs. Patients with certain genetic alleles and underlying diseases are vulnerable to SCADRs. The exact pathogenesis of SCADRs is not well defined. Nonetheless, recent study showed that reactive metabolites and immunological processes have a significant role in SCADRs. Conclusions The different SCADRs reactions are attributed by different intrinsic factors, such as genetic polymorphisms, gender, age and race as well as extrinsic factors, such as underlying diseases. Different regions and culprit drugs also play a role in the various types of SCADRs.

    Perineural (Tarlov) cysts are most often found in the sacral region and are rare in the cervical spine. Although they are usually asymptomatic, a small number of those at the lumbosacral level have been known to produce localized or radicular pain. Few reports are available on symptomatic perineural cysts in the cervical spine and it has not been discussed how they should be managed. We present here a case of cervical perineural cysts with persistent radicular pain where the pain was adequately managed with repetitive transforaminal epidural steroid injection (TFESI). The patient had experienced intractable pain in the posterior neck and left upper extremity for more than 7 years. The nature of the pain was cramping and a tingling sensation, which was aggravated in the supine position. Magnetic resonance imaging revealed a perineural cyst in the neural foramen of left C7 root. The patient underwent three repetitive TFESIs targeted at the root. Each injection provided incremental relief, which lasted more than 6 months. Follow-up image revealed shrinkage of the cyst. This case illustrates in detail the clinical manifestation of a rare symptomatic perineural cyst in the cervical region and to our knowledge is the first to report the beneficial effect of repetitive TFESI.

    Dentinogenesis imperfecta (DI) associated with osteogenesis imperfecta (OI) is a genetic disorder that affects the connective tissues and results in dentine dysplasia. This case report discusses the systemic and dental manifestations of OI and DI in a 4-year-old child, with moderate presentation of both disorders, who was treated at King Fahd Military Medical Complex in Dhahran. Dental treatment included the use of strip and stainless-steel crowns under local anesthesia, as well as behavior modification techniques. Rigorous home care instructions, including reinforcement of the oral hygiene practice and avoidance of any episode that may lead to bone fracture, were discussed with the parents. The case was reevaluated at 3-month follow-up visits, wherein the medical and dental histories were updated, the child's growth was monitored, periodic clinical and radiographic examinations were performed, and the oral hygiene was evaluated via the debris index score and caries risk assessment. Further treatment of the permanent dentition may be needed in the future.

    Full Text Available Obesity consistently associated with the development of a number of chronic diseases, leading to a decrease in quality of life, disability and death. The article examines the connection between obesity and disease of the musculoskeletal system, describes the mechanisms by means of which obesity leads to the development of osteoarthritis. It is evident that reduction of body mass can slow the progression of osteoporosis. The own experience of non-pharmacological and pharmacological treatment of obesity with the use of orlistat in 50 obese patients with osteoarthritis of the knee II–III stage is presented. Treatment has resulted in a decrease in body weight, waist circumference, accompanied by a decrease in symptoms osteoarthritis among all the patients. Our results showed that the addition of orlistat to standard osteoarthritis scheme leads to significant reduction in weight and reduction of clinical manifestations of osteoarthritis. According to the above, the drugs that have impact on weight loss, should be included in the treatment regimen of patients with osteoarthritis and obesity.

    Takayasu arteritis (TA) is the third most common childhood vasculitis and its clinical manifestations depend on the arteries involved. We report a case of a 9-year-old boy with multiple aneurysms in carotid and iliac arteries, subclavian and coronary arteries, and abdominal aorta. At the age of 7 years, he presented with recurrent fever and hepatosplenomegaly. An angio-computed tomography scan showed aneurysms in the left subclavian artery, abdominal aorta, and both proximal iliac arteries. He was diagnosed with TA and was treated with corticosteroids, aspirin, and enalapril. One year later, he was admitted to Dr Roberto Gilbert Children’s Hospital because of intracranial hemorrhage. Angiography revealed enlargement of aneurysms enlargement and new aneurysms. He also developed portal hypertension. Treatment with intravenous corticosteroids, azathioprine, and monthly intravenous cyclophosphamide was begun. After 6 months of no improvement, infliximab was begun. The aim of this article was to report the concurrence of coronary involvement and portal vein hypertension in pediatric TA because there were scarce reports on this matter. PMID:27895519

    Zika virus (ZKV) is an arbovirus of the Flaviviridae family, which includes West Nile, dengue fever, yellow fever, and Japanese encephalitis virus. It is transmitted by the Aedes genus of mosquitoes. Before 2015, ZKV outbreaks occurred in areas of Africa, the Pacific Islands, and Southeast Asia. The current large outbreak, which began in Brazil, has also emerged throughout a large part of South/Central America, a number of islands in the Caribbean, including Puerto Rico, the Virgin Islands, and Mexico. A sudden rise in the numbers of infants reported born with microcephaly in Brazil, and the detection of the single-stranded positive RNA virus in the amniotic fluid of affected newborns, has captured medical, mainstream media, and global political attention, causing considerable concern in a post-Ebola global community considerably more focused on the threat of internationally transmissible diseases. The goal of this article is to provide an overview of ZKV for clinicians, with the emphasis on pathogenesis, clinical manifestations, diagnosis, and treatment/preventive measures.

    AIM: To investigate the incidence of CD117-positive immunohistochemical staining in previously diagnosed gastrointestinal (GI) tract stromal tumors (GTST) and to analyze the tumors' clinical manifestations and prognostic factors.METHODS: We retrospectively reviewed 91 cases with a previous diagnosis of GI stromal tumor, leiomyoma, or leiomyosarcoma. Tissue samples were assessed with CD117, CD34, SMA and S100 immunohistochemical staining. Clinical and pathological characteristics were analyzed for prognostic factors.RESULTS: CD117 was positive in 81 (89 %) of 91 tissue samples. There were 59 cases (72.8 %) positive for CD34,13 (16 %) positive for SMA, and 12 (14.8 %) positive for S100. There was no gender difference in patients with CD117-positive GIST. Their mean age was 65 years. There were 44 (54 %) tumors located in the stomach and 29 (36 %)in the small intestine. The most frequent presenting symptoms were abdominal pain and GI bleeding. The mean tumor size was 7.5±5.7 cm. There were 35 cases (43.2 %)with tumors >5 cm. The tumor size correlated significantly with tumor mitotic count and resectability. Tumor size, mitotic count, and resectability correlated significantly with tumor recurrence and survival. There was recurrent disease in 39 % of our patients, and their mean survival after recurrence was 16.6 months. Most recurrences were at the primary site or metastatic to the liver. Twenty-six percent of our patients died of their disease.CONCLUSION: Traditional histologic criteria are not specific enough to diagnose GIST. This diagnosis must be confirmed with CD117 immunohistochemical staining. Prognosis is dependent on tumor size, mitotic count, and resectability.

    Full Text Available Objective  To summarize the clinical and MRI imaging features, treatment and prognosis of reversible splenial lesion syndrome (RESLES. Methods  The clinical manifestation and MRI imaging appearances of 13 RESLES patients were retrospectively evaluated and the pertinent literatures of RESLES were reviewed. Results  Of the 13 cases (11 males and 2 female, aged from 13 to 58 years, 1 was complicated with spontaneous intracranial hypotension syndrome, 1 with epidemic hemorrhagic fever, 1 with antiepileptic drug withdraw, 1 with pituitary crisis combining Sjogren syndrome, 1 with still disease, and 8 cases were complicated with viral encephalitis (meningoencephalitis. The first MRI imaging was performed from 2 to 39 days after onset. All the lesions were measured about 1-2cm, located in the central area and involved no other part of corpus callosum. They were characterized by high signal intensity on FLAIR and T2 sequences, with mild signal reduction on T1 sequence, and hyperintensity on DWI with low apparent diffusion coefficient (ADC values. The lesions formed as ovoid and boomerang. Following intravenous injection of contrast medium in 3 cases, no enhancement was found in the splenial lesions. All the patients completely recovered or obviously improved after appropriate treatments. The splenial lesions disappeared or obviously weakened on the follow-up MRI imaging, ranging from 6 to 30 days after first MRI imaging. Conclusions  RESLES is characterized by the MRI finding as a reversible lesion with transiently reduced diffusion in the splenium of corpus callosum. Symptoms of RESLES are various, the outcome is favorable in most cases, and the etiology and pathogenesis of RESLES are still unclear. DOI: 10.11855/j.issn.0577-7402.2016.10.09

    Full Text Available The paper describes the results of research aimed at assessing the current conditions related to clinical laboratory technologist professional development. A descriptive cross study covering the period between November 2013 and January 2014 is presented. Several techniques for identifying and hierarchically arranging professional developmental related problems were used to study a sample at the Faculty of Health Technology of the Medical University “Carlos Juan Finlay”. The study involved heads of teaching departments and methodologists of health care technology specialties; moreover a survey and a content test were given graduate clinical laboratory technicians. The authors reached at the conclusion that clinical laboratory technologist professional development is limited and usually underestimate the necessities and interests of these graduates. Likewise, a lack of systematization and integration of the biomedical basic sciences contents and the laboratory diagnosis is noticeable.

    Aim Although the association between primary immunodeficiency and autoimmunity is already well-known, it has once again become a topic of debate with the discovery of newly-defined immunodeficiencies. Thus, investigation of the mechanisms of development of autoimmunity in primary immunodefficiency and new target-specific therapeutic options has come to the fore. In this study, we aimed to examine the clinical findings of autoimmunity, autoimmunity varieties, and treatment responses in patients who were genetically diagnosed as having primary immunodeficiency. Material and Methods The files of patients with primary immunodeficiency who had clinical findings of autoimmunity, who were diagnosed genetically, and followed up in our clinic were investigated. The demographic and clinical features of the patients and their medical treatments were evaluated. Results Findings of autoimmunity were found in 30 patients whose genetic mutations were identified. The mean age at the time of the first symptoms was 8.96±14.64 months, and the mean age of receiving a genetic diagnosis was 82.55±84.71 months. The most common diseases showing findings of autoimmunity included immune dysregulation, polyendocrinopathy, enteropathy X-linked syndrome (16.7%); autoimmune lymphoproliferative syndrome (10%); lipopolysaccharide-responsive beige-like anchor protein deficiency (10%); and DiGeorge syndrome (10%). Twelve (40%) patients showed findings of autoimmunity at the time of first presentation. The most common findings of autoimmunity included inflammatory bowel disease, inflammatory bowel disease-like findings (n=14, 46.7%), immune thrombocytopenic purpura (n=11, 36.7%), and autoimmune hemolytic anemia (n=9, 30.0%). A response to immunosupressive agents was observed in 15 (50%) patients. Ten patients underwent hematopoietic stem cell transplantation. Six patients were lost to follow-up due to a variety of complications. Conclusion Autoimmunity is frequently observed in patients with

    Imported parasitosis represents an increasingly frequent diagnostic challenge for microbiology laboratories. A surge in immigration and international travel has led to a rise in the number of imported cases of parasitosis, and this trend is expected to continue in the future. The present article addresses this challenge by reviewing recommended diagnostic approaches and tests. Currently, microscopy is always recommended when analysing blood samples for parasites. If malaria is suspected, rapid antigen testing (including at least HRP2 antigen) should also be performed. The work-up for suspected leishmaniasis should include serology, culture, and in selected cases detection of antigen in urine. In suspected Chagas disease, two different serological tests should be performed. PCR for blood protozoa is highly sensitive, although it cannot be used to rule out Chagas disease, since this condition may be present without parasitemia. Accurate diagnosis of intestinal amebiasis usually requires PCR or antigen detection tests. In helminthiasis, traditional microscopy may need to be complemented with other tests, such as agar plate culture for strongyloidiasis, Og4C3 antigen detection for bancroftian filariasis, and antibody detection test for filariasis and schistosomiasis.

    2016-10-01

    Amyopathic dermatomyositis is a rare, idiopathic, connective tissue disease that presents with dermatologic lesions of classic dermatomyositis but lacks the myopathy of this disease. Cutaneous manifestations may include Gottron's sign, heliotrope rash, and characteristic patterns of poikiloderma. There is a substantial risk for developing interstitial lung disease or malignancy in patients with amyopathic dermatomyositis. A literature review of amyopathic dermatomyositis was performed using the PubMed medical database. The key features of amyopathic dermatomyositis, including autoantibodies, clinical presentation and dermatologic manifestations, epidemiology, history, associated malignancies, management, and pathogenesis, are summarized in this review. Cancer (solid tumor) (73/79, 89 %) and hematologic malignancies (9/79, 11 %) were reported in 79 patients, with three patients having more than one malignancy. In addition, there were six patients with amyopathic dermatomyositis who had tumor of unknown primary, and eight patients with cancer-associated amyopathic dermatomyositis for whom no additional details were provided. From the group of 73 tumors for whom primary origin and sex were available, malignancy of the genitourinary organs (24/73, 33 %), aerorespiratory organs (15/73, 21 %), and breast (14/73, 19 %) were the most commonly observed solid organ tumors. Tumors of the genitourinary organs (15/48, 31 %) and breast (14/48, 29 %) were the most frequent neoplasms in women, accounting for 29 of 48 (60 %) cancers, with the most common sites being breast (14/48, 29 %), ovary (8/48, 17 %), and cervix or uterus (5/48, 10 %). In men, tumors of the aerorespiratory (9/25, 36 %) and genitourinary (9/25, 36 %) tracts were the most common neoplasms, accounting for 72 % (18/25) of cancers; the most common sites of primary malignancy were nasopharyngeal (6/25, 24 %), bladder (4/25, 16 %), and either colorectal, lung or prostate cancer (three cancers each

    Aim To perform SWOT (strengths, weaknesses, opportunities, and threats) analysis of a clinical laboratory as an economic model that may be used to improve business performance of laboratories by removing weaknesses, minimizing threats, and using external opportunities and internal strengths. Methods Impact of possible threats to and weaknesses of the Clinical Laboratory at Našice General County Hospital business performance and use of strengths and opportunities to improve operating profit were simulated using models created on the basis of SWOT analysis results. The operating profit as a measure of profitability of the clinical laboratory was defined as total revenue minus total expenses and presented using a profit and loss account. Changes in the input parameters in the profit and loss account for 2008 were determined using opportunities and potential threats, and economic sensitivity analysis was made by using changes in the key parameters. The profit and loss account and economic sensitivity analysis were tools for quantifying the impact of changes in the revenues and expenses on the business operations of clinical laboratory. Results Results of simulation models showed that operational profit of €470 723 in 2008 could be reduced to only €21 542 if all possible threats became a reality and current weaknesses remained the same. Also, operational gain could be increased to €535 804 if laboratory strengths and opportunities were utilized. If both the opportunities and threats became a reality, the operational profit would decrease by €384 465. Conclusion The operational profit of the clinical laboratory could be significantly reduced if all threats became a reality and the current weaknesses remained the same. The operational profit could be increased by utilizing strengths and opportunities as much as possible. This type of modeling may be used to monitor business operations of any clinical laboratory and improve its financial situation by

    It is meaningful to discuss the "present and future of laboratories" for the development of laboratories and education of medical technologists. Laboratory staff must be able to perform urgent high-quality tests and take part in so-called team-based medicine and should be proud of devising systems that efficiently provide laboratory data for all medical staff. On the other hand, there may be staff with a poor sense of professionalism who work no more than is expected and too readily ask firms and commercial laboratories to solve problems. Overwork caused by providing team-based medicine and a decrease in numbers of clinical chemists are concerns. The following are hoped for in the future. Firstly, laboratory staff will become conscious of their own high-level abilities and expand their areas of work, for example, bioscience, proteomics, and reproductive medicine. Secondly, a consultation system for medical staff and patients will be established. Thirdly, clinical research will be advanced, such as investigating unknown pathophysiologies using laboratory data and samples, and developing new methods of measurement. Lastly, it is of overriding importance that staff of laboratory and educational facilities will cooperate with each other to train the next generation. In conclusion, each laboratory should be appreciated, attractive, positive regarding its contribution to society, and show individuality.

    Background Human T-lymphotropic virus type 1 (HTLV-1) is known to cause HTLV-associated myelopathy (HAM)/tropical spastic paraparesis and adult T cell leukemia. A growing body of evidence links HTLV-1 infection with an increasing spectrum of disease, including uveitis, periodontal disease, arthropathy, sicca syndrome, and neurologic deficits. Objectives Despite recent findings, the natural history of HTLV-1 infection remains poorly defined. This study was designed to better characterize initial clinical and neurological findings in individuals diagnosed with HTLV-1 infection. Study Design We conducted a cross-sectional study of 71 individuals recently diagnosed with HTLV-1 and 71 uninfected age- and sex-matched blood donors in Salvador, Brazil. Subjects were administered a standardized questionnaire and underwent physical exam. Results HTLV-1 infected subjects were significantly more likely than controls to report complaints of hand and foot numbness (OR=5.3; 95% CI: 1.8-15.3; p=0.002 and OR=4.0; 95% CI: 1.3-12; p=0.013 respectively), difficulty running (OR=4.0; 95% CI: 1.1-14.2, p=0.032), nocturia (OR=5.0, 95% CI: 1.1-22.8, p=0.038), arthralgia (OR 3.3, 95% CI: 1.4-7.7, p=0.006), and photophobia (OR 3.3, 95% CI: 1.4-7.7, p=0.006). Conclusions Neurologic, ocular and rheumatologic complaints may be the first manifestations of HTLV-1 infection. Therefore, all patients presenting with initial diagnosis should be rigorously screened for these symptoms. PMID:21388871

    Full Text Available Objective: to compare clinical manifestations, course, mental status in duodenal ulcer (DU patients with a history of perforated ulcer and its uncomplicated course.Subjects and methods. One hundred and thirteen patents with DU were examined. Group 1 included 61 patients with uncomplicated DUand Group 2 comprised 52 patients with a history of perforated ulcer. A comparison group consisted of 20 patients who had undergone laparotomy. Physical and mental status examinations, esophagogastroduodenoscopy (EGDS, and 24-hour pH-metry were performed.Results. Classical pain syndrome was observed in 75 % of the patients with uncomplicated DU. Prior to perforation, the pain and dyspeptic syndromes were distinguished only by a significantly lower degree in Group 2; following perforation, the pain syndrome was recorded more frequently, it was more extensive, meal-unrelated, and similar to that in the patients who had undergone laparotomy and had diminished appetite (36.5 %. EGDS showed that the complicated course was accompanied by the significantly higher incidence of erosive esophagitis (21.2 %, gastritis (51.9 %, duodenitis (25.0 %, multiple ulcers (28.8 %, and larger ulcers. 24-hour pH-metry indicated that the level of hyperacidity in Group 2 was higher and the circadian intragastric pH variations were less marked than those in uncomplicated DU. The patients with a history of perforated ulcer showed a high rate of anxiety and depressive changes. Conclusion. In complicated DU, marked monotonic hyperacidity causes common erosive-ulcerative lesions in the gastroduodenal area in relatively mild pain syndrome, late referrals, and long-term ulcer healing. After perforation followed by wound closure, the pain and dyspeptic syndromes become more pronounced, which is associated with anxiety and depressive changes in the mental status, as well as with early referrals and less healing time.

    Fabry disease is an X-linked lysosomal storage disorder due to deficiency of alpha-Galactosidase A, causing accumulation of globotriaosylceramide and elevated plasma globotriaosylsphingosine (lysoGb3). The diagnostic value and clinical relevance of plasma lysoGb3 concentration was investigated. All male and adult female patients with classical Fabry disease could be discerned by an elevated plasma lysoGb3. In young pre-symptomatic Fabry heterozygotes, lysoGb3 levels can be normal. Individuals carrying the R112H and P60L mutations, without classical Fabry symptoms, showed no elevated plasma lysoGb3. Multiple regression analysis showed that there is no correlation of plasma lysoGb3 concentration with total disease severity score in Fabry males. However, plasma lysoGb3 concentration did correlate with white matter lesions (odds ratio: 6.1 per 100 nM lysoGb3 increase (95% CI: 1.4-25.9, p=0.015). In females, plasma lysoGb3 concentration correlated with overall disease severity. Furthermore, plasma lysoGb3 level was related to left ventricular mass (19.5+/-5.5 g increase per 10 nM lysoGb3 increase; p=0.001). In addition, it was assessed whether lifetime exposure to lysoGb3 correlates with disease manifestations. Male Fabry patients with a high lysoGb3 exposure (>10,000 U), were moderately or severely affected, only one mildly. Female patients with a low exposure (1000 U showed disease complications. Plasma lysoGb3 is useful for the diagnosis of Fabry disease. LysoGb3 is an independent risk factor for development of cerebrovascular white matter lesions in male patients and left ventricular hypertrophy in females. Disease severity correlates with exposure to plasma lysoGb3.

    One hundred and four workers ingested excessive levels of arsenic in an accident caused by leakage of pipeline in a copper-smelting factory. Clinical examinations were performed by physicians in a local hospital. Excreted urinary arsenic species were determined by cold trap hydride generation atomic absorption spectrometry. In the initial toxic phase, gastrointestinal symptoms were predominant (83 people, 79.8%). Most patients showed leucopenia (72 people, 69.2%), and increased serum alanine aminotransferase (84 people, 80.8%) and aspartate aminotransferase (58 people, 55.8%). Thirty-five patients (33.6%) had elevated red blood cells in urine. After 17 days of admission, many subjects (45 people, 43.3%) developed peripheral neuropathy and 25 of these 45 patients (24.0%) showed a decrease in motor and sensory nerve conduction velocity. In the comparison of urinary arsenic metabolites among subacute arsenic-poisoned, chronic high arsenic-exposed and control subjects, we found that subacute arsenic-poisoned patients had significantly elevated proportions of urinary inorganic arsenic (iAs) and methylarsonic acid (MMA) but reduced proportion of urinary dimethylarsinic acid (DMA) compared with chronic high arsenic-exposed and control subjects. Chronic exposed subjects excreted higher proportions of iAs and MMA but lower proportions of DMA in urine compared with control subjects. These results suggest that gastrointestinal symptoms, leucopenia, and hepatic and urinary injury are predominant in the initial phase of subacute arsenic poisoning. Peripheral neuropathy is the most frequent manifestation after the initial phase. The biomethylation of arsenic decreases in a dose rate-dependent manner.

The clinical manifestations of MF include splenomegaly, consequent to extramedullary hematopoiesis, cytopenias, and an array of potentially debilitating abdominal and constitutional symptoms. Dysregulated Janus kinase (JAK-signal transducer and activator of transcription signaling underlies secondary disease-associated effects in MF, such as myeloproliferation, bone marrow fibrosis, constitutional symptoms, and cachexia. Common fatal complications of MF include transformation to acute leukemia, thrombohemorrhagic events, organ failure, and infections. Potential complications from hepatosplenomegaly include portal hypertension and variceal bleeding, whereas extramedullary hematopoiesis outside the spleen and liver – depending on the affected organ – may result in intracranial hypertension, spinal cord compression, pulmonary hypertension, pleural effusions, lymphadenopathy, skin lesions, and/or exacerbation of abdominal symptoms. Although allogeneic stem cell transplantation is the only potentially curative therapy, it is suitable for few patients. The JAK1/JAK2 inhibitor ruxolitinib is effective in improving splenomegaly, MF-related symptoms, and quality-of-life measures. Emerging evidence that ruxolitinib may be associated with a survival benefit in intermediate- or high-risk MF suggests the possibility of a disease-modifying effect. Consequently, ruxolitinib could provide a treatment backbone to which other (conventional and novel

    Full Text Available Groundwater pollution has become a drastic problem principally because of nature and wide spread use of modern chemicals viz. pesticides and fertilizers. Excessive application of fertilizers as well as organic wastes and sewage has been implicated in the nitrogen pollution of groundwater. Therefore, the issue of rising nitrate concentration in groundwater has become a subject of extensive research in India and Rajasthan in particular. In natural water, nitrate ((NO3- N is usually 100ppm and in organic matters (amine and /or amides resulting in the production of nitrosamines (carcinogens. Number of cases (human and livestock, suffering from gastric cancer have been observed. Reverse osmosis (RO process has great potential in the mitigation of nitrate ion containing waters. Generally, the presence of particular substances may affect the removal of specific ions. The presence of di-hydrogen phosphate ions (DHP-ions in the feed solution enhances the nitrate removal efficiency of the polyamide RO membrane. In this present research work, a Flmtec TW30, polyamide thin-film composite, RO membrane was used for nitrate removal through RO set up. The rejection of individual nitrate was found to be around 76%. After addition of KH2¬PO4 to the feed containing nitrate ions the rejection was improved up to 84. This high level of increment in rejection of nitrate ion indicates the possible usage of KH2¬PO4 in RO for nitrate removal. This fact of removal is due to the K+ ions binding to the electronic lone-pairs of polyamide membrane holding di-hydrogen phosphate ions. This establishes a negative layer on the surface of the membrane. The diffusion of nitrate through the membrane is diminished by the formed layer. Present manuscript delineates clinical manifestations of nitrate toxicity and mitigation of nitrate ion by means of state-of-the-art reverse osmosis technology.

    Toxocariasis is a parasitic infection produced by helminths that cannot reach their adult stage in humans. For their etiological species (Toxocara canis and Toxocara cati), man is a paratenic host. Infection by such helminths can produce a variety of clinical manifestations, such as: visceral larvae migrans syndrome, ocular larvae migrans syndrome and covert toxocariasis. In the visceral larvae migrans syndrome, the organs that are mainly involved include liver, lungs, skin, nervous system, muscles, kidneys and the heart. Regarding the latter, the importance of cardiovascular manifestations in toxocariasis, as well as its clinical relevance, has increasingly begun to be recognized. The current article is based on a systematic information search, focused mainly on the clinical and pathological aspects of cardiovascular manifestations in toxocariasis, including its pathophysiology, laboratory findings, diagnosis and therapeutical options, with the objective of highlighting its importance as a zoonosis and its relevance to the fields of cardiovascular medicine in adults and children.

    Full Text Available OBJECTIVE: To determine the serum levels of interferon alpha in childhood-onset systemic lupus erythematosus patients, their first-degree relatives and healthy controls and to evaluate the associations between serum interferon alpha and disease activity, laboratory findings and treatment features. METHODS: We screened consecutive childhood-onset systemic lupus erythematosus patients in a longitudinal cohort at the pediatric rheumatology unit of the State University of Campinas between 2009 and 2010. All patients demonstrated disease onset before the age of 16. Disease status was assessed according to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI. Interferon alpha levels were measured using an enzyme-linked immunoabsorbent assay. RESULTS: We included 57 childhood-onset systemic lupus erythematosus patients (mean age 17.33±4.50, 64 firstdegree relatives (mean age 39.95±5.66, and 57 healthy (mean age 19.30±4.97 controls. Serum interferon alpha levels were significantly increased in childhood-onset systemic lupus erythematosus patients compared to their firstdegree relatives and healthy controls. Interferon alpha levels were significantly increased in patients with positive dsDNA antibodies, patients with cutaneous vasculitis, patients with new malar rash and patients who were not receiving medication. Interferon alpha levels correlated with C3 levels and systemic lupus erythematosus Disease Activity Index scores. In addition, we observed an inverse correlation between patient age and interferon alpha levels. CONCLUSION: Interferon alpha may play a role in the pathogenesis of childhood-onset systemic lupus erythematosus, especially in cutaneous manifestations and dsDNA antibody formation. The observation that interferon alpha levels are increased in patients who are not taking medication should be investigated in

    Colorectal cancer (CRC) is a major public health problem, and its incidence is rising in developing countries. However, studies characterizing CRC clinicopathological features in cases from developing countries are still lacking. The goal of this study was to evaluate clinicopathological and demographic features in one of the largest CRC studies in Latin America.The study involved over 1525 CRC cases recruited in a multicenter study in Colombia between 2005 and 2014 as part of ongoing genetic and epidemiological studies. We gathered clinicopathological data such as age at diagnosis, sex, body mass index, tobacco and alcohol consumption, family history of cancer, and tumor features including location, histological type, and stage. Statistical analyses were performed to test the association between age of onset, sex, and clinical manifestations.The average age at CRC diagnosis was 57.4 years, with 26.5% of cases having early-onset CRC (diagnosed by age 50 years). Most cases were women (53.2%; P = 0.009), 49.2% were overweight or obese, 49.1% were regular alcohol drinkers, 52% were smokers/former smokers, and 12.2% reported relatives with cancer. Most tumors in the study were located in the rectum (42.7%), were adenocarcinomas (91.5%), and had advanced stage (T3-T4, 79.8%). Comparisons by sex found that male cases were more likely to be obese (36.5% vs 31.1%; P = 0.001), less likely to have a family history of cancer (9.7% vs 15.3%; P = 0.016), and more likely to have advanced-stage tumors (83.9% vs 76.1%; P = 0.036). Comparisons by age of onset found that early-onset cases were more likely to be women (59.3% vs 51.0%; P = 0.005) and report a family history of cancer (17.4% vs 10.2%; P = 0.001).To our knowledge, our study is the largest report of clinicopathological characterization of Hispanic CRC cases, and we suggest that further studies are needed to understand CRC etiology in diverse Hispanic populations.

    Basic calcium phosphate and pyrophosphate calcium crystals are the 2 main calcium-containing crystals that can deposit in all skeletal tissues. These calcium crystals give rise to numerous manifestations, including acute inflammatory attacks that can mimic alarming and threatening differential diagnoses, osteoarthritis-like lesions, destructive arthropathies, and calcific tendinitis. Awareness of uncommon localizations and manifestations such as intraspinal deposition (eg, crowned dens syndrome, tendinitis of longus colli muscle, massive cervical myelopathy compression) prevents inappropriate procedures and cares. Coupling plain radiography, ultrasonography, computed tomography, and synovial fluid analysis allow accurate diagnosis by directly or indirectly identifying the GRAAL of microcrystal-related symptoms.

    The high incidence of recurrent chronic hepatitis C after a course of antiviral therapy determines the urgency of determining the extrahepatic reservoirs of hepatitis C virus (HCV). The most extrahepatic site for the virus is peripheral mononuclear cells (PMC). Assuming that there may be HCV replication in the PMC), these cells can be considered as a potential reservoir of HCV infection. The most common extrahepatic manifestation of HCV is cryoglobulinemia, the genesis of which may be active viral replication in the cells of the immune system. There is evidence that HCV is detectable just in the tissues of the involved organs. Thus, most systemic manifestations may be directly associated with extrahepatic HCV replication.

    Full Text Available Background: Occupational lead poisoning is common in workers of some industries, but lead hepatotoxicity has rarely been reported. Several animal studies have revealed lead induced liver damage but clinical studies concerning the manifestations of lead induced liver toxicity in humans are scares. This study was designed to investigate the clinical manifestations and pathological parameters of hepatic dysfunction and its relationship with blood and urine lead concentrations in a car battery-manufacturing workers. Methods: This cross sectional study was carried out in Mashhad, Iran, during April-June 2011. One hundred and twelve workers underwent blood and urine sampling for determination of lead concentrations and liver function tests. Clinical signs and symptoms of possible lead hepatotoxicity were investigated. Results: Mean (±SD age of the workers was 28.78 (±5.17 yr with a daytime work of 8.67 (±1.41 h and mean work duration of 3.89 (±2.40 yr. Mean blood lead concentration (BLC and urine lead concentration (ULC were 398.95 (±177.41 µg/l and 83.67(±50 μg/l, respectively. We found no correlation between the clinical findings and BLC or ULC. A weak correlation (R: 0.27, P=0.087 between serum alkaline phosphatase concentration and BLC was obtained. No significant relationship was found between other liver function tests and BLC or ULC. Conclusion: We found no specific clinical and laboratory abnormalities of liver in the workers of car battery manufacturer who had chronic lead toxicity. Further investigations with more specific laboratory tests such as LDH5 and gamma glutamyl transferase (GGT as well as novel biomarkers of metal induced hepatotoxicity might be helpful in evaluating lead hepatotoxicity.

    Full Text Available Background: The interface between clinicians and laboratory staff is where the two meet and work together to provide quality care to their clients (patients. Effectiveness of the interface depends on the way the two groups of professionals relate to and communicate with each other. The number and type of tests requested and the use of the test results for clinical decision making can be influenced by the interface between clinicians and laboratory staff. A model to understand the factors and dynamics around the interface is lacking.Objectives: To propose a new conceptual model to gain insight and analyse factors that influence the laboratory–clinical staff interface.Methods: To develop the conceptual model, a literature study was performed, regulatory guidelines and standards for laboratories were analysed and discussions were held with experts on the topic.Result: A conceptual model and analytical framework provided good guidance in understanding and assessing the organisational and personal factors shaping the interface. The model was based on three elements: (1 the three phases of communication (pre-analytical, analytical and post-analytical; (2 the organisational and personal factors of interaction; and (3 the socio-political, economic and cultural context in which clinicians and laboratory staff operate.Conclusion: Assessment of the interface between clinicians and laboratory workers can be performed in a systematic way. Applying this model will provide information to managers of health institutions and heads of laboratories and clinical departments about what happens when clinicians and laboratory staff interact, thus aiding them in designing strategies to improve this interface.

    The presence of a human tail is a rare and intriguing phenomenon. While cases have been reported in the literature, confusion remains with respect to the proper classification, definition, and treatment methods. We review the literature concerning this anatomical derailment. We also consider the importance of excluding underlying congenital anomalies in these patients to prevent neurological deficits and other abnormal manifestations.

    Dermatomyositis (DM) is a common idiopathic inflammatory myopathy. The pathogenesis is considered to be microangiopathy affecting skin and muscle. The cutaneous manifestations of DM are the most important aspect of this disease, and their correct evaluation is important for early diagnosis. The skin signs are various: Some are pathognomonic or highly characteristic, and others are compatible with DM. Recently, DM has been categorized into several disease subsets based on the various autoantibodies present in patients. Sometimes, characteristic cutaneous manifestations are strongly associated with the presence of specific autoantibodies. For example, anti-Mi-2 antibody is associated with the classic features of DM, including heliotrope rash, Gottron's papules, the V-neck sign, the shawl sign, cuticular overgrowth, and photosensitivity. Frequent cutaneous features in anti-transcriptional intermediary factor 1 gamma (TIF1γ)-positive patients are diffuse photoerythema, including "dusky red face," while skin ulcerations, palmar papules (inverse Gottron), diffuse hair loss, panniculitis, and oral pain and/or ulcers are sometimes associated with anti-melanoma differentiation-associated gene 5 product (MDA5) antibody. Here, we review important cutaneous manifestations seen in patients with DM, and we examine the relationship between the skin changes and myositis-associated autoantibodies. Correct evaluation of cutaneous manifestations and myositis-associated autoantibodies should help the clinician in the early diagnosis of DM, for a quick recognition of cutaneous signs that may be the symptom of onset before muscle inflammation.

    Regular review of the management of bioterrorism is essential for maintaining readiness for these sporadically occurring events. This review provides an overview of the history of biological disasters and bioterrorism. I also discuss the recent recategorization of tier 1 agents by the U.S. Department of Health and Human Services, the Laboratory Response Network (LRN), and specific training and readiness processes and programs, such as the College of American Pathologists (CAP) Laboratory Preparedness Exercise (LPX). LPX examined the management of cultivable bacterial vaccine and attenuated strains of tier 1 agents or close mimics. In the LPX program, participating laboratories showed improvement in the level of diagnosis required and referral of isolates to an appropriate reference laboratory. Agents which proved difficult to manage in sentinel laboratories included the more fastidious Gram-negative organisms, especially Francisella tularensis and Burkholderia spp. The recent Ebola hemorrhagic fever epidemic provided a check on LRN safety processes. Specific guidelines and recommendations for laboratory safety and risk assessment in the clinical microbiology are explored so that sentinel laboratories can better prepare for the next biological disaster.

    Full Text Available CONTEXT AND OBJECTIVE: Acute anterior uveitis is a common extra-articular manifestation in spondyloarthritis patients. The aim of this study was to compare demographic, clinical, laboratory and treatment data among spondyloarthritis patients with and without acute anterior uveitis. DESIGN AND SETTING: This was a cross-sectional analytical study at the Rheumatology Outpatient Clinic of the Evangelical University Hospital, Curitiba, Brazil. METHODS: Spondyloarthritis patients with without acute anterior uveitis were compared regarding demographic data, spondyloarthritis subtype, peripheral arthritis, enthesitis, disease activity, functional index, physical examination, radiological involvement, HLA-B27 and treatment. RESULTS: Presence of acute anterior uveitis was not found to have any relationship with functional index, degree of radiological involvement, peripheral arthritis or enthesitis. Acute anterior uveitis showed a negative association with skin manifestations (P = 0.04 and a trend towards higher disease activity (P = 0.06. CONCLUSION: In the study sample, it could not be shown that AAU had any association with the functional and radiological prognoses. The patients with spondyloarthritis with and without acute anterior uveitis did not differ clinically except for a higher proportion of ankylosing spondylitis and smaller presence of skin involvement in those with uveitis.

    Despite an increasing focus on simulation as a learning strategy in nursing education, there is limited evidence on the transfer of simulated skills into clinical practice. Therefore it's important to increase knowledge of how clinical skills laboratories (CSL) can optimize students' learning for development of professional knowledge and skills, necessary for quality nursing practice and for patient safety. Thus, the aim was to describe nursing students' experiences of learning in the CSL as a preparation for their clinical practice. Interviews with 16 students were analysed with content analysis. An overall theme was identified - walking the bridge - in which the CSL formed a bridge between the university and clinical settings, allowing students to integrate theory and practice and develop a reflective stance. The theme was based on categories: conditions for learning, strategies for learning, tension between learning in the skills laboratory and clinical settings, and development of professional and personal competence. The CSL prepared the students for clinical practice, but a negative tension between learning in CSL and clinical settings was experienced. However, this tension may create reflection. This provides a new perspective that can be used as a pedagogical approach to create opportunities for students to develop their critical thinking.

    Pallister-Killian syndrome is a rare, multi-system developmental diagnosis typically caused by tetrasomy of chromosome 12p that exhibits tissue-limited mosaicism. The spectrum of clinical manifestations in Pallister-Killian syndrome is wide and includes craniofacial anomalies, clefts, ophthalmologic, audiologic, cardiac, musculoskeletal, diaphragmatic, gastrointestinal, genitourinary, and cutaneous anomalies in association with intellectual disability and seizures. Growth parameters are often normal to elevated at birth with deceleration of growth postnatally. No formal estimate of the prevalence of Pallister-Killian syndrome has been made. Here, we report the clinical findings in 59 individuals with Pallister-Killian syndrome who were ascertained at Pallister-Killian syndrome Foundation family meetings held in the summers of 2006, 2008, 2009, and 2010. In addition, the clinical findings of 152 cases reported in the medical literature were reviewed and compared to the cohort examined here. Several novel clinical characteristics were identified through detailed dysmorphology examinations of this cohort and reassertion of a mild developmental variant is described. This report expands the clinical manifestations of Pallister-Killian syndrome and highlights the variable expressivity of this diagnosis with important implications for diagnosis and counseling.

    There are a large number of ideas concerning the systematization of clinical laboratory management. Therefore many types of laboratory systems have been constructed. As our hospital is not large, we adopted a small scale laboratory system. In introducing it, we expected not only an increase in value-added labor productivity by automating laboratory tests, but also an improvement in technologist's cost awareness. Consequently, new system equipment has itself performed the former in many sections, but not the latter. Improvement in cost awareness was caused by the technologist's routine work in managing reagent and material stocks. We found that this soft-type systematization has been more important than the advanced hard-type system.

    Full Text Available Abstract Systemic primary carnitine deficiency (CDSP is an autosomal recessive disorder of carnitine transportation. The clinical manifestations of CDSP can vary widely with respect to age of onset, organ involvement, and severity of symptoms, but are typically characterized by episodes of hypoketotic hypoglycemia, hepatomegaly, elevated transaminases, and hyperammonemia in infants; skeletal myopathy, elevated creatine kinase (CK, and cardiomyopathy in childhood; or cardiomyopathy, arrhythmias, or fatigability in adulthood. The diagnosis can be suspected on newborn screening, but is established by demonstration of low plasma free carnitine concentration (SLC22A5 gene. The incidence of CDSP varies depending on ethnicity; however the frequency in the United States is estimated to be approximately 1 in 50,000 individuals based on newborn screening data. CDSP is caused by recessive mutations in the SLC22A5 gene. This gene encodes organic cation transporter type 2 (OCTN2 which transport carnitine across cell membranes. Over 100 mutations have been reported in this gene with the c.136C > T (p.P46S mutation being the most frequent mutation identified. CDSP should be differentiated from secondary causes of carnitine deficiency such as various organic acidemias and fatty acid oxidation defects. CDSP is an autosomal recessive condition; therefore the recurrence risk in each pregnancy is 25%. Carrier screening for at-risk individuals and family members should be obtained by performing targeted mutation analysis of the SLC22A5 gene since plasma carnitine analysis is not a sufficient methodology for determining carrier status. Antenatal diagnosis for pregnancies at increased risk of CDSP is possible by molecular genetic testing of extracted DNA from chorionic villus sampling or amniocentesis if both mutations in SLC22A5 gene are known. Once the diagnosis of CDSP is established in an individual, an echocardiogram, electrocardiogram, CK concentration

    Full Text Available The central immunological disturbance in systemic lupus erythematosus (SLE is autoantibody production. Some of these antibodies affecting components of the cell nucleus are the major characteristics of SLE. The present study was aimed to assess importance of anticardiolipin (ACL antibody and its association with clinical state in SLE patients. A cross sectional study was performed on 100 patients with SLE referred to rheumatology outpatient clinic in Ekbatan hospital in Hamadan (Iran between 2007 and 2008. Serum samples were extracted and screened for IgG and IgM using an ACL enzyme-linked immunosorbent assay. Up to 36% of patients were positive for ACL antibody that was more frequent in women than men (39.8% versus 8.3%. No association was revealed between ACL antibody and age. Clinical manifestations of antiphospholipid antibody syndrome were observed in 23.0% of patients that was more prevalent in ACL positive group compared with ACL negative group (41.7% versus 125%. The prevalence of other manifestations including pregnancy-related disorders (recurrent abortion, central nervous system defects, and deep vein thrombosis was 33.3%, 25.0%, and 30.6% in ACL positive group and was 9.4%, 7.8%, and 7.8% in ACL negative group that all were more frequent in the former group. The prevalence of thrombocytopenia was also higher in ACL positive group than another group (22.2% versus 15.6%. Among ACL positive patients with clinical manifestations of antiphospholipid antibody syndrome, 86.6% had medium to high titer of ACL. Our study emphasized value of (ACL antibody to assess clinical status in SLE patients

  20. Generalized subcutaneous edema as a rare manifestation of dermatomyositis: clinical lesson from a rare feature.

    Haroon, Muhammad

    2011-04-01

    Generalized subcutaneous edema is a very rare manifestation of inflammatory myopathies. A 61-year-old woman presented with classic signs and symptoms of dermatomyositis. She was also noted to have generalized edema that was so florid that an alternative diagnosis was considered. Her disease was resistant to corticosteroids, azathioprine, and mycophenolate mofetil. Intravenous administration of immunoglobulins was started because of marked worsening of her disease-muscle weakness, generalized anasarca, and involvement of her bulbar muscles. This led to dramatic resolution of her subcutaneous edema and significant improvement of her skin and muscle disease. As the initial screen for malignancy was negative, a positron emission tomography-computed tomography scan was requested, which interestingly showed a metabolically active cervical tumor. Anasarca is an unusual manifestation of dermatomyositis. In treatment-refractory cases, it seems reasonable to consider positron emission tomography scan in excluding underlying malignant disease.

  1. Acute Respiratory Distress Syndrome as the Initial Clinical Manifestation of an Antisynthetase Syndrome

    2016-01-01

    Antisynthetase syndrome has been recognized as an important cause of autoimmune inflammatory myopathy in a subset of patients with polymyositis and dermatomyositis. It is associated with serum antibody to aminoacyl-transfer RNA synthetases and is characterized by a constellation of manifestations, including fever, myositis, interstitial lung disease, mechanic's hand-like cutaneous involvement, Raynaud phenomenon, and polyarthritis. Lung disease is the presenting feature in 50% of the cases. We report a case of a 60-year-old female with acute respiratory distress syndrome (ARDS), which later proved to be an unexpected and initial manifestation of anti-Jo-1 antibody–positive antisynthetase syndrome. The present case showed resolution of ARDS after treatment with high-dose corticosteroids. Given that steroids are not greatly beneficial in the treatment of ARDS, it is likely that the improvement of the respiratory symptoms in this patient also resulted from the prompt suppression of the inflammatory systemic response by corticosteroids.

    Hepatic encephalopathy (HE) shows a wide spectrum of neuropsychiatric manifestations. A combined effort with neuropsychological and psychometric evaluation has to be performed to recognize the syndrome, whereas minimal HE (MHE) is largely under-recognized. Subtle symptoms of MHE can only be diagnosed through specialized neuropsychiatric testing. Early diagnosis and treatment may drastically improve the quality of life for many cirrhotic patients. Further research to gain better insight into the pathophysiology and diagnostic accuracy of HE will help determine future management strategies.

    An important objective of laboratory management is to adjust the laboratory's capability to the needs of patients' care as well as economy. The consequences of management may be changes in laboratory organization, equipment, or personnel planning. At present only one's individual experience can be used for making such decisions. We have investigated whether the techniques of operations research could be transferred to a clinical laboratory and whether an adequate simulation model of the laboratory could be realized. First we listed and documented the system design and the process flow for each single laboratory request. These input data were linked by the simulation model (programming language SIMSCRIPT II.5). The output data (turnaround times, utilization rates, and analysis of queue length) were validated by comparison with the current performance data obtained by tracking specimen flow. Congruence of the data was excellent (within +/- 4%). In planning experiments we could study the consequences of changes in order entry, staffing, and equipment on turnaround times, utilization, and queue lengths. We conclude that simulation can be a valuable tool for better management decisions.

    Full Text Available In systemic lupus erythematosus- (SLE various antibodies are produced against cells including platelets and result in thrombocytopenia. In the literature, the incidence of thrombocytopenia varied from 7% to 52%, in seven series of SLE patients with a mean cumulative percentage of 14.5% (1-5. SLE patients referred to the Lupus Unit of the Rheumatology Research Center, Tehran University for Medical Sciences (Shariati Hospital during the period of 1975 to 1977 were included in this study. T/irombocytopenic patients were selected and 72 items were studied. Tiie incidence of thrombocytopenia in Iranian SLE patients was 16.6%, which is similar to the mean cumulative percentage mentioned above.

    Full Text Available The aim of this study was to assess the role of HLA-B*27 and it's subtypes in determining severity and clinical manifestations of ankylosing spondylitis (AS.A total of 163 AS patients were assessed for clinical manifestations and severity using structured questionnaires. HLA-B*27 screening and B*27 sub-typing were performed by PCR.One hundred twenty two patients (74.8% were B*27 positive. The male to female ratio, peripheral arthritis, steroid use, intense dorsal kyphosis and decrease of cervical slope had a significantly higher frequency in B*27 positive patients compared to B*27 negative ones (p=0.01, 0.001, 0.01, 0.04 and 0.04, respectively. However, the age of diagnosis was significantly lower in B*27 positive patients (p=0.005. Trend in uveitis and some severity markers including: BASMI and ASQoL were toward higher values in B*27 positive group with no significant difference. After controlling confounding variables, significant relationship was found only between B*27 and BASMI (p=0.01. B*27 subtypes in patients were included B*2705: 48.4%, B*2702: 42.6%, B*2704: 5.7% and B*2707: 3.3%. No significant differences were seen for severity markers and clinical manifestations between subtypes; although trend toward lower values of severity markers, less intense dorsal kyphosis and less decrease of cervical slope were observed in B*2704 and B*2707 versus other polymorphisms.Clinical features and severity of AS is influenced by HLA-B*27. Trend toward higher severity markers in B*2705 and B*2702 versus other polymorphisms might be subject of interest for evaluation in other ethnicities with concentration to other novel susceptibility genes co-inherited in each B*27 subtype.

    The threat of bioterrorism has led to increased concerns over the availability of biological select agents and toxins (BSAT). Congress has implemented several public laws that have led to the development of federal regulations by the Centers for Disease Control and Prevention (CDC) and the US Department of Agriculture. The CDC regulation 42 CFR 73 has a direct impact on all clinical laboratories that may at some time identify BSAT in a clinical specimen. The Department of Defense has imposed a more stringent layer of regulation called biological surety (biosurety) on top of the requirements of 42 CFR 73 for military laboratories that possess BSAT. However,42 CFR 73 falls into the framework of biosurety. Both sets of regulations have four pillars (safety, physical security, agent account-ability, and personnel reliability) that are built on a foundation of training and covered by a roof of management (operations and plans).

    The laboratory and particularly clinical immunology laboratories have an essential role in diagnosing and monitoring systemic lupus erythematosus (SLE), as well as other connective tissue diseases. The role of the clinical immunology laboratory in these diseases is to confirm or exclude diagnosis, to monitor disease activity, and to identify subgroup of patients. To obtain the best results in terms of diagnostic performance and clinical usefulness, the following recommendations should be fulfilled: anti-nuclear antibodies (ANA) determination by indirect immunofluorescence on Hep-2 cells is an effective screening assay in patients with clinical features of SLE. A negative ANA test makes the diagnosis of SLE unlikely. Anti-dsDNA antibodies are highly specific for SLE and are associated with renal involvement. The method of choice for anti-dsDNA is the Farr assay; however, the necessity of using radioactive materials reduces its applicability. As an alternative, immunofluorescence on Crithidia Luciliae can be used in the diagnostic phase due to its high specificity. The detection of antibodies to extractable nuclear antigens (ENA) and to phospholipids (lupus anticoagulant and anti-cardiolipin antibodies) is useful in identifying subgroups of patients at risk for some clinical manifestations. Anti-dsDNA measurement with a quantitative assay (the Farr assay or ELISA) is currently the best method to monitor disease activity along with complement levels. New assays (anti-C1q and anti-nucleosome antibodies) have been recently proposed for the diagnosis (anti-nucleosome) and monitoring of SLE patients (anti-C1q and anti-nucleosome antibodies), with promising results.

    Chikungunya fever, caused by "Chikungunya virus," is an arbovirus disease transmitted by the bite of infected mosquitoes belonging to the genus Aedes. Chikungunya fever epidemics have been reported from several countries around the world. The disease that was silent for nearly 32 years re-emerged in the October 2005 outbreak in India that is still ongoing. The incubation period ranges from 3 to 12 days. The onset is usually abrupt and the acute stage is characterized by sudden onset with high-grade fever, severe arthralgias, myalgias, and skin rash. Swollen tender joints and crippling arthritis are usually evident. In the chronic stage, relapses that include sensation of fever, asthenia, exacerbation of arthralgias, inflammatory polyarthritis, and stiffness may be evident. Neurological, ocular, and mucocutaneous manifestations have also been described. Chronic arthritis may develop in about 15% of the patients. Viral culture is the gold standard for the diagnosis of Chikungunya fever. Reverse transcription polymerase chain reaction and real-time loop-mediated isothermal amplification have also been found to be useful. Serodiagnostic methods for the detection of immunoglobulin M and immunoglobulin G antibodies against Chikungunya virus are more frequently used. Chikungunya is a self-limiting disease; however, severe manifestations such as meningoencephalitis, fulminant hepatitis, and bleeding manifestations may sometimes be life-threatening. Treatment is symptomatic and supportive. Prevention by educating the community and public health officials, vector control measures appear to be the best approach at controlling Chikungunya fever as no commercially available vaccine is available for public use in India for this condition presently.

    The majority of children with allergic diathesis, living in the Andizhan region of the Uzbek SSR manifest the signs of stable abnormalities of thyroid function, that aggravate immunological alterations and the course of the process. This prompts the use in these children of therapeutic measures aimed at correction of the activity of the thyroid apparatus. With this purpose in view, the children with allergic diathesis associated with increased thyroid function may be administered aqueous solution of potassium iodide whereas those with functional thyroid deficiency may be given thyroidin in proper age-associated doses.

    Lymphatic filariasis is a major public health problem in India with 412 million people living in bancroftian endemic areas and is a major cause of clinical morbidity. Twenty million people are reported to suffer from chronic disease manifestations such as lymphoedema, hydrocele or elephantiasis. At least twice the number have been shown to suffer from acute and occult filarial infections in an endemic area without diagnosis. Due to non-availability of suitable diagnostic test for confirming filaria aetiology other than parasitological examination, no significant study on filariasis in children has been reported earlier. Studies in our laboratory for more than a decade showed usefulness of microfilarial excretory-secretory antigen in confirming filarial aetiology in acute and occult infections in adults as well as in children. This study reports acute and atypical manifestations such as lymphadenopathy, asthmatic bronchitis, pulmonary eosinophilia, mono-arthritis, recurrent URI, pneumonia, nutritional anemia, pain in abdomen etc. in children living in filaria endemic area having no microfilaraemia but showing filaria aetiology by immunomonitoring for the presence of antibody or antigen and responding to optimal DEC therapy.

    Endocrine neoplasia syndromes feature a wide spectrum of benign and malignant tumors of endocrine and non-endocrine organs associated with other clinical manifestations. This study outlines the main clinical features, genetic basis, and molecular mechanisms behind two multiple endocrine neoplasia syndromes that share quite a bit of similarities, but one can be inherited whereas the other is always sporadic, Carney complex (CNC) and McCune-Albright (MAS), respectively. Spotty skin pigmentation, cardiac and other myxomas, and different types of endocrine tumors and other characterize Carney complex, which is caused largely by inactivating Protein kinase A, regulatory subunit, type I, Alpha (PRKAR1A) gene mutations. The main features of McCune-Albright are fibrous dysplasia of bone (FD), café-au-lait macules and precocious puberty; the disease is caused by activating mutations in the Guanine Nucleotide-binding protein, Alpha-stimulating activity polypeptide (GNAS) gene which are always somatic. We review the clinical manifestations of the two syndromes and provide an update on their molecular genetics.

    The present study has revealed some specific clinical and functional features in the patients presenting with neurologic manifestations of deforming dorsopathies and concomitant osteoarthrosis. The negative influence of the latter condition on the pain intensity, microcirculation, and duration of the exacerbation of neurologic syndrome has been demonstrated based on the analysis of correlational relationships between the severity of referred projectional nerve root pain and articular pain syndrome. Special emphasis is laid on the interrelation between the duration of pain syndrome and characteristics of microcirculation.

    Full Text Available OBJECTIVE: To identify clinical, laboratorial and radiographic predictors for Bordetella pertussis infection.METHODS: This was a retrospective study, which analyzed medical records of all patients submitted to a molecular dignosis (qPCR for B. pertussis from September 2011 to January 2013. Clinical and laboratorial data were reviewed, including information about age, sex, signs/symptoms, length of hospitalization, blood cell counts, imaging findings, coinfection with other respiratory pathogens and clinical outcome.RESULTS: 222 cases were revised. Of these, 72.5% had proven pertussis, and 60.9% were under 1 year old. In patients aging up to six months, independent predictors for B. pertussisinfection were (OR 8.0, CI 95% 1.8-36.3; p=0.007 and lymphocyte count >104/µL (OR 10.0, CI 95% 1.8-54.5; p=0.008. No independent predictors of B. pertussisinfection could be determined for patients older than six months. Co-infection was found in 21.4% of patients, of which 72.7% were up to six months of age. Adenovirus was the most common agent (40.9%. In these patients, we were not able to identify any clinical features to detect patients presenting with a respiratory co-infection, even though longer hospital stay was observed in patients with co-infections (12 vs. 6 days; p=0.009.CONCLUSIONS: Cyanosis and lymphocytosis are independent predictors for pertussis in children up to 6 months old.

    Full Text Available Analysis of feed for the presence of fungi and mycotoxins is a request necessary to meet in order to ensure a healthy and economical production in livestock. These tests are related to legal regulation which prescribes the maximum legislated content (MLC, both for the presence of mycotoxins and the total number of fungi in certain feeds. Health problems that can occur during the production of animals are sometimes caused by the presence of mycotoxins in the feed. Laboratory testing is a good practice to confirm a suspicion, and allows timely treatment of contaminated feed. Potential problems arise under circumstances when there is a clinical outcome of mycotoxicosis and animal and laboratory findings suggest that the obtained values are below the level that is within the MLC. For these reasons, the subject of our research was to investigate the occurrence of mycotoxins and mold in feed, as well as the clinical presentation for animals that were fed with the feed with allowed values of these agents according to the recommended levels. The aim of this paper was to highlight the problems associated with clinical correlation of sick animals and laboratory findings, and suggest their overcoming. In the period of one year, a total of 176 samples of feed (complete mixture for broilers, corn and soy products were examined for the presence of fungi, 106 samples were examined for the presence of mycotoxins and 26 flocks of broilers and turkeys were clinically observed. Standard methods were used for isolation of molds and the ELISA test was used for the detection of mycotoxins. Clinical and pathomorphological observation of the flocks was done to determine the natural indicators of production. Studies indicated a problem because clinical and pathomorphological findings in some cases were not correlated with laboratory findings of molds and mycotoxins in the feed, and in some cases it did not necessarily mean that the animals were healthy.

    Full Text Available Nonlinear elastic response in rock is established as a robust and representative characteristic rock rather than a curiosity. We show measurements of this behaviour from a variety of experiments on rock taken over many orders of magnitude in strain and frequency. The evidence leads to a pattern of unifying behaviour in rock: (1 Nonlinear response in rock is ubiquitous. (2 The response takes place over a large frequency interval (dc to 105 kHz at least. (3 The response not only occurs, as is commonly appreciated, large strains but also at small strains where this behaviour and the manifestations of this behaviour are commonly disregarded.

    A 52-year-old male patient presented to the emergency department because of malaise and frequent dizziness. The ECG revealed high-grade atrioventricular block that required placement of a temporary pacemaker. There were no other abnormalities in physical and echocardiographic examination, and coronary angiography excluded the presence of coronary artery disease. IgM and IgG antibodies against Borrelia were positive, and antibiotic therapy with ceftriaxone at the dose of 2 g/die for 15 days resulted in rapid regression of atrioventricular block. Seven-day ECG recording immediately after discharge and 24h ECG monitoring at 40 days confirmed the total disappearance of atrioventricular block. This represents a case of atrioventricular block as the first manifestation of Borrelia infection (Lyme disease). A prompt diagnosis and antibiotic therapy usually result in complete resolution of atrioventricular block without the need for a permanent pacemaker.

    Medium-chain acyl-CoA dehydrogenase deficiency (MCADD) is the most common fatty acid oxidation disorder. Typically, undiagnosed individuals are asymptomatic until an episode of increased energy demand and fasting occurs, resulting in metabolic derangement. Phenotypic heterogeneity has been increasingly realized, with reports of both neonates and adults manifesting with life-threatening symptoms including encephalopathy, rhabdomyolysis, and cardiac failure. If diagnosed presymptomatically, outcome is favorable basically by avoidance of fasting. Early detection by newborn screening (NBS) has significantly reduced the incidence of severe adverse events including deaths. In this manuscript we focus on the natural course of the disease in both children and adults. Although NBS for MCADD has been successfully established, continuing efforts need to be made to avoid acute crises and deterioration of outcome in screened patients entering adolescence and adulthood.

    Background: Tramadol is a centrally acting analgesic with opioid and nonopioid properties, which extensively used in the relief of mild to moderate pain. Tramadol poisoning is a common cause of acute pharmaceutical poisoning in Iran. There are a few studies about clinical and laboratory findings related to acute tramadol poisoning. Therefore, the aim of this study was to demonstrate the clinical and laboratory findings in tramadol acute poisoning cases. Materials and Methods: This was a retrospective descriptive study of patients with acute tramadol poisoning who referred to Loghman Hakim Hospital Poison Center during January to April 2012. Data such as patient's age, sex, time of ingestion, ingested dose, cause of poisoning, mean duration of hospitalization, patient's clinical presentations, laboratory findings, therapeutic measures, and patient's outcome have collected in a predesigned checklist. Results: A total of 144 patients including 111 men (77%) and 33 women (23%) with acute tramadol poisoning was included in this study. The mean ingested dose was 1971.2 mg (100-20000 mg). Seizure (47.91%) was the most frequent clinical symptom. Blood gas on admission showed pH (7.3 ± 0.1), PCO2 (49.7 ± 8.6 mmHg) and HCO3− (24.1 ± 3.8 mEq/L), indicating pure acute respiratory acidosis may be occurred in tramadol-intoxicated patients. There were significant differences between tramadol-intoxicated cases with and without a seizure with regard to the time interval between ingestion and admission on hospital, ingested dose and PCO2. Conclusion: Seizure and rise of PCO2 were the most findings in this study. PMID:25535500

    The antiviral action of natural killer (NK) cells is regulated by a wide repertoire of germ-line encoded membrane receptors which recognize the expression of certain self-molecules on target cells. Among the receptors, killer cell immunoglobulinlikereceptor (KIR) which recognizes the expression of human leukocyte antigen (HLA) class I has a predominant role in regulating the effector functions of NK cells, particularly in viral infections. We studied a total of 128 hepatitis B virus (HBV)patients (15 acute, 43 asymptomatic, 27 chronic and 43 with other liver diseases) while attending the Department of Medical Gastroenterology, Government Rajaji Hospital, Madurai, India, and 128 ethnic matched control to find the association between the KIR : HLA genes and differential manifestations of HBV. KIR and its ligand HLA polymorphism were identified by DNAPCR methods. The activatory receptor KIR-2DS1 was significantly elevated in various disease categories, namely asymptomatic, chronic and other HBV, except acute HBV infection. Whereas, KIR 2DS3 in acute and chronic patients and KIR 2DS5 and 3DS1 in asymptomatic individuals. Among various KIR–HLA combinations, homozygous 2DS2:C1 and individuals with 3DSI:BW4 (OR = 3.23, CI = 1.55–6.7, Pc = 0.02) are associated with HBV asymptomatism, while most of the two domain inhibitory receptors with their ligands showed significant risk in other liver diseases. Further, KIR3DL1 : HLA Bw4Iso80 (OR = 3.89, 95% CI = 1.58–9.55, Pc = 0.004) is related with higher risk for asymptomatic infection when compared with chronic HBV. Thus, the select KIR : HLA alleles and combinations seem to direct the NK cell activities and immune response in different directions resulting in varied symptoms and manifestations in the subgroups of HBV-infected patientsstudied.

    Although transplantation of solid organs has become a more standardized method of treatment, liver transplantation represents an exceptional multidisciplinary clinical procedure requiring understanding of specific pathophysiological changes that occur in the end stage of liver disease. Liver transplantation has been performed at Merkur University Hospital since 1998, with 360 transplantations performed to date. The most common indications are alcohol liver disease, cirrhosis caused by hepatitis B and C virus, hepatocellular carcinoma and cryptogenetic liver cirrhosis. Laboratory tests required for liver transplantation are performed at Department of Clinical Chemistry, Merkur University Hospital, accredited according to ISO 15189 in 2007 for the areas of clinical chemistry, laboratory hematology and coagulation, laboratory immunology-cell immunophenotyping, and molecular diagnosis. The complexity of liver transplant patients requires constant interaction between the anesthesiologist team and clinical laboratory, which has to ensure fast and efficient intraoperative monitoring of biochemical and liver profile: electrolytes and acid-base status, complete blood count, coagulation profile and monitoring of graft function according to the individual patient's health status. Dynamics of intraoperative changes is measured in whole arterial blood samples on a Nova Biomedical Stat Profile Critical Care Xpress mobile acid-base analyzer. Frequent monitoring of ionized calcium and magnesium levels is very important because of citrated blood transfusion and for appropriate therapeutic procedure. During anhepatic stage, there is a progressive increase in lactate level concentration. After reperfusion, a rapid increase in lactate clearance is an excellent indicator of stable graft initial function and its adequate size. During the transplantation procedure, there is usually a biphasic acid-base disturbance characterized by metabolic acidosis and then by metabolic alkalosis. The

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

    The practice of cardiology continues to evolve along with a better understanding of the pathophysiology of cardiovascular disease and the development of new therapeutic procedures. Consequently, new demands are being made on the in vitro diagnostics industry to improve the performance of existing cardiac markers and to develop novel markers for new cardiac disease indications. Indeed, in the last 20 years there has been a progressive increase in new laboratory tests for markers of cardiac diseases. Several highly sensitive and/or specific assays for the detection of myocardial ischemic damage as well as some immunoassays for cardiac natriuretic hormones, now considered a reliable marker of myocardial function, have become commercially available. In parallel, a growing number of some novel risk factors, which can be assessed and monitored by laboratory methods, have been added to the classical risk factors for cardiovascular disease. Finally, the recent explosion of genetic analysis may soon place at the clinical cardiologist's disposal many laboratory tests for defining the diagnosis at the molecular level, assessing new risk factors, and better targeting the pharmaceutical approaches in patients with cardiovascular disease. In the present article, after a brief description of the analytical tests included in these four groups, each group's impact on clinical cardiology is discussed in detail.

    Full Text Available Objective. The physical function of PM/DM patients after remission induction therapy remains unknown adequately. The aim of our study was to evaluate the present status of physical dysfunction and to clarify the clinical manifestations and myositis-specific autoantibodies (MSAs associated with physical dysfunction after treatment in PM/DM. Methods. We obtained clinical data including the age at disease onset, gender, disease duration, laboratory data prior to initial treatment, and the specific treatment administered. We evaluated disease activity and physical dysfunction after treatment using the core set provided by the International Myositis Assessment and Clinical Studies Group. Results. 57% of the 77 enrolled patients with PM/DM had troubles in daily living after treatment. At the enrolment, disease activity evaluated by physicians was only revealed in 20% of patients. In a multivariate analysis, the age at disease onset, female gender, and CK levels before treatment were significantly associated with the severity of physical dysfunction after treatment. Anti-SRP positivity was associated with more severe physical dysfunction after treatment than anti-ARS or anti-MDA5. Conclusions. Half of the PM/DM patients showed physical dysfunction after treatment. Age at disease onset, gender, CK level before treatment, and anti-SRP were significant predictors associated with physical dysfunction after treatment in PM/DM.

    Full Text Available Skin diseases are indicators of HIV/AIDS which correlates with WHO clinical stages. In resource limited environment where CD4 count is not readily available, they can be used in assessing HIV patients. The study aims to determine the mucocutaneous manifestations in HIV positive patients and their correlation with WHO clinical stages. A prospective cross-sectional study of mucocutaneous conditions was done among 215 newly diagnosed HIV patients from June 2008 to May 2012 at adult ART clinic, Wesley Guild Hospital Unit, OAU Teaching Hospitals Complex, Ilesha, Osun State, Nigeria. There were 156 dermatoses with oral/oesophageal/vaginal candidiasis (41.1%, PPE (24.4%, dermatophytic infections (8.9%, and herpes zoster (3.8% as the most common dermatoses. The proportions of dermatoses were 4.5%, 21.8%, 53.2%, and 20.5% in stages 1–4, respectively. A significant relationship (using Pearson’s Chi square with P value <0.05 was obtained between dermatoses and WHO clinical stages. Pearson’s correlation coefficient showed a positive correlation between the number of dermatoses and the WHO clinical stages. Dermatoses can therefore serve as diagnostic and prognostic markers in resource limited settings to initiate HAART in clinical stages 3 and 4.

    Objective:To investigate variations of Th1/Th2 cytokine levels, as well as their correlation with eczema development and clinical manifestation in aged patients.Methods: A total of 92 patients (above 60 years old) with eczema diagnosed by the outpatient department of dermatology and venerology of our hospital were included as the eczema group, while 60 aged patients without eczema as the healthy group. Patients' serum levels of Th1/Th2 cytokines were examined for inter-group comparison and stratified analysis as per clinical manifestation. Results:Serum levels of interleukin (IL)-2, IL-4, IL-10, IL-12, tumor necrosis factor (TNF)-α and interferon (IFN)-γ were all significantly higher in patients of the eczema group than the healthy group. Acute stage levels of IL-2, IL-4, IL-10 and IFN-γ were significantly higher in patients of the eczema group than the healthy group. There was no significant difference in the levels of IL-12 and TNF-α between patients of the acute stage and those of the chronic stage. And no significant difference existed in the levels of IL-2, IL-4, IL-10, IL-12, TNF-α and IFN-γ between generalized and localized eczema patients.Conclusion:Compared with the healthy population, Th1/Th2 cytokine levels are significantly different in eczema patients, especially those in the acute stage.

    Full Text Available The potential of Drug-Drug Interactions (DDI in prescription have high incidence around the world, including Indonesia. However, scientific evidence regarding DDI in Indonesia is not available. Therefore, in this study we have conducted survey in 2 pharmacies in Bandung against pediatric prescription given by pediatrician. These prescriptions then analyzed the potential for DDI contained in the prescription and clinical manifestation. The analysis showed that in pharmacy A, there are 33 prescriptions (from a total of 155 prescriptions that have potential DDI, or approximately 21.19% (2 prescriptions have the potential DDI major categories, 23 prescriptions categorized as moderate, and 8 prescriptions as minor. In Pharmacy B, there are 6 prescriptions (from a total of 40 prescriptions or 15% of potential DDI (4 prescriptions categorized as moderate and 2 prescriptions as minor. This result showed that potential DDI happened less than 50% in pediatric prescription from both pharmacies. However, this should get attention because DDI should not happen in a prescription considering its clinical manifestations caused by DDI. Moreover, current pharmaceutical care refers to patient oriented than product oriented. In addition, further study for the pediatric prescription on DDI incidence in large scale need to be investigated.

    Disseminated intravascular coagulation (DIC) is the most frequent coagulation disorder associated with metastatic prostate adenocarcinoma. However, DIC with enhanced fibrinolysis as an initial presentation of prostate cancer is extremely rare. The appropriate treatment to control bleeding in these situations is challenging, controversial, and based on isolated case reports in the literature. A 66-year-old male presented at the emergency department with acute severe spontaneous ecchymoses localized to the limbs, laterocervical hematoma, and hemothorax. Prostate specific antigen level was 385 μg/L, bone scintigraphy revealed multiple bone metastases, and prostate biopsy confirmed adenocarcinoma (Gleason 9; 4 + 5). Laboratory investigation showed a pattern of enhanced fibrinolysis rather than the more common intravascular coagulation mechanism. Epsilon aminocaproic acid in monotherapy was initiated with a clear and rapid control of bleeding manifestations. This rare case of massive bleeding due to DIC with enhanced fibrinolysis as the first manifestation of prostate cancer suggests that in selected cases where the acute bleeding dyscrasia is clearly associated with a dominant fibrinolysis mechanism it is possible to use an approach of monotherapy with antifibrinolytics.

    The objective of this study was to examine the epidemiology and the clinical manifestations of typhoid fever as well as the susceptibility and strain relatedness of Salmonella typhi isolates in Lebanon from 2006 to 2007. A total of 120 patients with typhoid fever were initially identified from various areas of the country based on positive culture results for S. typhi from blood, urine, stools, bone marrow and/or positive serology. Clinical, microbiological and molecular analysis was performed on cases with complete data available. These results indicated that drinking water was an unlikely mode of transmission of the infection. Despite increasing reports of antimicrobial resistance among S. typhi isolates, the vast majority of these isolates were susceptible to various antibiotic agents, including ampicillin, cephalosporins, quinolones, and trimethoprim/sulfamethoxazole. Molecular analysis of the isolates revealed a predominance of one single genotype with no variation in distribution across the geographical regions.

    Ninety-four episodes of Klebsiella pneumoniae bloodstream infection were identified at a university hospital in Japan. After excluding extended-spectrum beta lactamase-producing strains, 83 blood isolates from these patients were assayed in terms of their bacterial phenotypes such as the mucoid and hypermucoviscosity phenotypes. Bacterial phenotypes were correlated with the patients' clinical manifestations. The hypermucoviscosity phenotype was significantly associated with septic shock at the onset of infections (odds ratio, 15.92; 95% confidence interval, 1.27-468.12), but was not associated with liver abscess formation. Mortality was determined by the presence of septic shock. RmpA gene was associated with the induction of the hypermucoviscosity phenotype. These results reveal unique roles of bacterial phenotypes on the patient's clinical condition in K. pneumoniae bacteremia.

    Autosomal recessive polycystic kidney disease (ARPKD), although less frequent than the dominant form, is a common, inherited ciliopathy of childhood that is caused by mutations in the PKHD1-gene on chromosome 6. The characteristic dilatation of the renal collecting ducts starts in utero and can present at any stage from infancy to adulthood. Renal insufficiency may already begin in utero and may lead to early abortion or oligohydramnios and lung hypoplasia in the newborn. However, there are also affected children who have no evidence of renal dysfunction in utero and who are born with normal renal function. Up to 30 % of patients die in the perinatal period, and those surviving the neonatal period reach end stage renal disease (ESRD) in infancy, early childhood or adolescence. In contrast, some affected patients have been diagnosed as adults with renal function ranging from normal to moderate renal insufficiency to ESRD. The clinical spectrum of ARPKD is broader than previously recognized. While bilateral renal enlargement with microcystic dilatation is the predominant clinical feature, arterial hypertension, intrahepatic biliary dysgenesis remain important manifestations that affect approximately 45 % of infants. All patients with ARPKD develop clinical findings of congenital hepatic fibrosis (CHF); however, non-obstructive dilation of the intrahepatic bile ducts in the liver (Caroli's disease) is seen at the histological level in only a subset of patients. Cholangitis and variceal bleeding, sequelae of portal hypertension, are life-threatening complications that may occur more often in advanced cases of liver disease. In this review we focus on common and uncommon kidney-related and non-kidney-related phenotypes. Clinical management of ARPKD patients should include consideration of potential problems related to these manifestations.

  2. On the improvement of blood sample collection at clinical laboratories

    Science.gov (United States)

    2014-01-01

    Background Blood samples are usually collected daily from different collection points, such hospitals and health centers, and transported to a core laboratory for testing. This paper presents a project to improve the collection routes of two of the largest clinical laboratories in Spain. These routes must be designed in a cost-efficient manner while satisfying two important constraints: (i) two-hour time windows between collection and delivery, and (ii) vehicle capacity. Methods A heuristic method based on a genetic algorithm has been designed to solve the problem of blood sample collection. The user enters the following information for each collection point: postal address, average collecting time, and average demand (in thermal containers). After implementing the algorithm using C programming, this is run and, in few seconds, it obtains optimal (or near-optimal) collection routes that specify the collection sequence for each vehicle. Different scenarios using various types of vehicles have been considered. Unless new collection points are added or problem parameters are changed substantially, routes need to be designed only once. Results The two laboratories in this study previously planned routes manually for 43 and 74 collection points, respectively. These routes were covered by an external carrier company. With the implementation of this algorithm, the number of routes could be reduced from ten to seven in one laboratory and from twelve to nine in the other, which represents significant annual savings in transportation costs. Conclusions The algorithm presented can be easily implemented in other laboratories that face this type of problem, and it is particularly interesting and useful as the number of collection points increases. The method designs blood collection routes with reduced costs that meet the time and capacity constraints of the problem. PMID:24406140

    Grgić, Vjekoslav

    2007-01-01

    Vertebrogenic pain localised in the anterior thorax can imitate anginal pain ("pseudoangina pectoris"). The most common causes of vertebrogenic chest pain are segmental dysfunction and degenerative changes at the level of the lower cervical and upper middle thoracic spine. Segmental dysfunction is a source of pseudoradicular pain, and degenerative changes, before all disc hernia and dorsal osteophytes which are compressing corresponding nerve roots, are the sources of radicular pain which irradiates in the chest. Because of its similarity with angina pectoris, the intense chest pain caused by the cervical radiculopathy which is often followed by heart rhythm disorders and nonspecific changes of the ST-T-segment in ECG, is called "cervicogenic angina". The attacks of vertebrogenic chest pain are not rare even in patients with angina pectoris. Because of superimposed vertebrogenic pain, the manifestation of pain in patients with angina pectoris can be considerably changed which can be misinterpreted as unstable angina. From therapeutic aspect it is very important to distinguish vertebrogenic from anginal pain. That is, the change of cardiological therapy will not eliminate possible attacks of vertebrogenic pain in patients with angina pectoris. From the aspect of most recent understandings, the article describes etiopathogenesis, characteristics, diagnosis and therapy of vertebrogenic chest pain, and also the differences between vertebrogenic and anginal pain.

    Stojšin Ivana M.

    2007-01-01

    Full Text Available Dental defects of erosive nature are defined as irreversible losses of dental tissue, caused by long lasting and repeated action of acids that dissolve top layer of hydroxyapatite and fluorideapatites crystal structure, under assumption that aggressive factor is not of bacterial nature. Acids that cause changes on teeth according to their origin are gastric, dietetic, or they are of environmental origin. Current way of life, as well as nutritional habits create potentially dangerous conditions for the hard dental tissue, for prevention of mineralization process causes defects of oral system homeostasis. Defects occur on primary teeth, as well as on permanent teeth. However, this happens once and a half time more frequently on primary teeth due to the weaker primary maturation. In initial phases, changes are localized in enamel and by their development the bottom locates in dentine. Defects appear as smooth, shiny, round concavities on caries immune positions, or as cupping of occlusal surfaces. The depth of an eroded lesion consists of the depth of the crater plus the depth of tissue demineralization at the base of the lesion. Early verification of the etiological factor, together with good knowledge of the manifested shape change has influence to the prevention of the crown of tooth loss, complete occlusion, mastication and speech.

    This article aims to reflect on which areas or tasks of microbiology laboratories could be unified with those of clinical biochemistry, hematology, immunology or pathology laboratories to benefit patients and the health system, as well as the areas that should remain independent since their amalgamation would not only fail to provide a benefit but could even jeopardize the quality of microbiological diagnosis, and consequently patient care. To do this, the distinct analytic phases of diagnosis are analyzed, and the advantages and disadvantages of amalgamation are evaluated in each phase. The pros and cons of the unification of certain areas such as the computer system, occupational risk units, customer service, purchasing logistics, and materials storage, etc, are also discussed. Lastly, the effect of unification on urgent microbiology diagnosis is analyzed. Microbiological diagnosis should be unique. The microbiologist should perform an overall evaluation of the distinct techniques used for a particular patient, both those that involve direct diagnosis (staining, culture, antigen detection techniques or molecular techniques) and indirect diagnosis (antibody detection). Moreover, the microbiology laboratory should be independent, with highly trained technicians and specialists in microbiology that provide added value as experts in infection and as key figures in the process of establishing a correct etiological diagnosis.

    The prognosis of patients with acute myocardial infarction (AMI) has notably improved in the past 20 years. Using the French Registry of ST-Elevation and Non-ST-elevation Myocardial Infarction (FAST-MI) 2010 registry, we investigated whether previous manifestations of atherosclerotic disease (i.e., previous MI, or a history of any form of atherosclerotic disease) are at truly increased risk compared with those in whom AMI is the first manifestation of the disease. FAST-MI 2010 is a nationwide French registry including 3,079 patients with AMI, among whom 1,062 patients had a history of cardiovascular atherosclerotic disease and 498 patients had a history of MI. Overall, patients with a history of atherosclerotic disease (or MI) were older compared with patients without known cardiovascular disease (71 ± 13 vs 63 ± 14 years) and had higher cardiovascular risk profiles and co-morbidities. Using fully adjusted Cox multivariate analysis, previous manifestations of atherosclerotic disease were associated with higher 3-year mortality (hazard ratio 1.80, 95% confidence interval 1.40 to 2.31; p <0.001) as history of previous MI alone (hazard ratio 1.32, 95% confidence interval 1.00 to 1.73; p = 0.048). Similar results were found in patients discharged alive. In conclusion, previous cardiovascular atherosclerotic disease represents 1/3 of patients with AMI and are strongly associated with worse long-term clinical outcomes. Intensive follow-up and therapy should be encouraged in this high-risk population.

    Fabrício C Dias

    Full Text Available BACKGROUND: Chagas disease affects approximately 10 million people mainly in Latin America. The immune regulation by the host seems to be an essential factor for disease evolution, and immune system inhibitory molecules such as CTLA-4 and PD-1 favor the maintenance of peripheral tolerance. Considering that polymorphisms at the immunoregulatory CTLA-4 and PDCD1 genes may alter their inhibitory function, we investigated the association of alleles, genotypes and haplotypes of polymorphic sites observed at the CTLA-4 and PDCD1 genes with different clinical manifestations of chronic Chagas disease (indeterminate, cardiac, digestive and mixed. METHODS: The polymorphisms at the CTLA-4 (-1722T/C, -318C/T and +49A/G and PDCD1 (PD-1.3G/A genes were typed using TaqMan methodology in 277 chronic Chagas disease patients classified into four groups, according to clinical characteristics, and 326 non-infected controls. RESULTS: Our results showed that CTLA-4 -1722CC genotype (22%, -1722C allele (27% and CTLA-4 TCG (8.6%, TCA (26% and CCA (15% haplotypes were strongly associated with the indeterminate form, while the CTLA-4-318CT genotype (82% and CTLA-4-318T allele (47% were found mainly in patients with the mixed form of the disease. The CTLA-4 TCG haplotype (10.2% was associated with the digestive form. On the other hand, the PD-1.3G/A polymorphism was not associated with chronic Chagas disease and its clinical manifestations. CONCLUSIONS: Here, we showed that alleles, genotypes and haplotypes reported to increase the expression of the regulatory molecule CTLA-4 were associated with the indeterminate form of the disease. Taken together, our data support the idea that polymorphic sites at immunoregulatory genes may influence the development of Chagas disease variants.

    Full Text Available The aim of this study was to compare clinical and laboratory findings of women with or without uterine leiomyoma.Study group consisted of 82 women with uterine leiomyoma and the control group comprised 42 healthy women. Women’s age, gravity, parity, blood groups, pattern of menstrual cycles, complaints at presentation, fertility, ultrasonographical findings, surgical operations and thyroid function tests were evaluated.There were no significant differences in blood group distribution, gravity, parity and thyroid function test results between the patients and the control subjects (P>0.05. A significant difference was found in the complaints at presentation between two groups (P<0.001. Mentrual cycles irregularity was more frequently found in the patients compared with the controls (57.3% vs. 42.9%, respectively, P=0.009. Although no infertile woman was found in the control group, 8.5% of patients were found to have infertility. The sensitivity of ultrasonography was found to be 97.6%. Except for the existence of higher infertility rate and the menstrual cycles irregularities, no significant difference was found in the clinical and laboratory findings between women with or without uterine leiomyoma. Therefore, physical examination and imaging methods are remained as the most important diagnostic tools for uterine leiomyoma.

    This paper describes visualization techniques that help identify hidden structures in clinical laboratory data. The visualization of data is helpful for a rapid and better understanding of the characteristics of data sets. Various charts help the user identify trends in data. Scatter plots help prevent misinterpretations due to invalid data by identifying outliers. The representation of experimental data in figures is always useful for communicating results to others. Currently, flexible methods such as smoothing methods and latent structure analysis are available owing to the presence of advanced hardware and software. Principle component analysis, which is a well-known technique used to reduce multidimensional data sets, can be carried out on a personal computer. These methods could lead to advanced visualization with regard to exploratory data analysis. In this paper, we present 3 examples in order to introduce advanced data analysis. In the first example, a smoothing spline was fitted to a time-series from the control chart which is not in a state of statistical control. The trend line was clearly extracted from the daily measurements of the control samples. In the second example, principal component analysis was used to identify a new diagnostic indicator for Graves' disease. The multi-dimensional data obtained from patients were reduced to lower dimensions, and the principle components thus obtained summarized the variation in the data set. In the final example, a latent structure analysis for a Gaussian mixture model was used to draw complex density functions suitable for actual laboratory data. As a result, 5 clusters were extracted. The mixed density function of these clusters represented the data distribution graphically. The methods used in the above examples make the creation of complicated models for clinical laboratories more simple and flexible.

    Purpose The disease concept of sick building syndrome (SBS) is still unclear. Ocular mucous membrane irritation is one of the major symptoms of SBS. However, the immunological aspects of the ocular complications of SBS are not yet clarified. The clinical and allergological aspects of SBS cases with ocular disorders with special reference to allergic conjunctival diseases (ACD) were analyzed, especially with respect to local immunological features. Methods Twelve cases of SBS with ocular findings and 49 cases of ACD (allergic conjunctivitis [AC], atopic keratoconjunctivitis [AKC], and vernal keratoconjunctivitis [VKC]) for comparison were evaluated. The clinical findings in SBS and ACD were scored, and tear film breakup time (BUT) was measured. Cytokine (interferon-γ [IFN-γ], interleukin [IL]-2, IL-4, IL-5, IL-6, IL-8, and IL-13) concentrations in tears were analyzed by cytometric bead arrays. Eosinophil count in peripheral blood, total IgE in serum, and multiple allergen simultaneous test (MAST) for antigen-specific IgE were also measured. Results In SBS, conjunctival lesions were observed in all cases, and corneal abnormalities were found in two-thirds of the cases. Limbal lesions were observed in 2 pediatric cases. Mean serum total IgE level in SBS was significantly higher than that in AC; however, it was significantly lower than that in AKC and VKC. Eosinophil count in peripheral blood and number of positive allergens in MAST were significantly lower in SBS than in AKC and VKC. Significant elevation of tear IL-4 was observed in SBS and ACD. However, in contrast to ACD, elevation of other cytokines in tears was not observed in SBS. Mean tear BUT in SBS was in the normal range. Conclusion From these results, SBS is thought to be partially induced by an allergic response. However, clinical dissociation of the ocular clinical findings and local immunological features in tear cytokines may suggest that SBS belongs to a different entity from ACD. PMID:28352150

    Full Text Available Increasing amounts of data have recenlty been published regarding ultrasonographic (US findings of osteoarthritic joints, but very few data concern hip joints. In the current study we described US patterns concerning 490 patients affected by symptomatic hip osteoarthritis (OA who underwent to intra-articular injections of hyaluronic products under US guidance. All patients were studied by US and X-ray of hip, clinical evaluation was assessed by the followings indexes: Lequesne, pain VAS, ICED, Global Physician Assessment and Global Patient Assessment. US findings were summarized in four main patterns, effusion and synovial proliferation were also detected. The aim of this study was to correlate US findings with clinical assessment and radiographic findings (according to Kellegren- Lawrence classification. Pearson’s r correlation coefficient were computed and come out significant and positive between X ray and US patterns and between clinical indexes and US patterns. Also the correlation between K-L score and US patterns showed a significant positive correlation indicating that higher K-L scores are associated with increasing abnormal US findings. Our data suggest that ultrasonography of the hip may give useful information about the state of synovial membrane, synovial fluid, joint margins and bone profile in hip OA. Further studies are needed to evaluate their prevalence in hip OA symptomatic and not-symptomatic patients and their correlation to treatment outcome.

    Full Text Available Brucellosis is a multisystem disease with diverse clinical presentations and involvement of the nervous system is considered to 5 to be 10% in adult patients and 1% in children. The presentations of neurobrucellosis includes meningoencephalitis, subarachnoid haemorrhage, myelitis, radiculoneuritis, intracerebral and epidural abscess, psychosis and vascular syndrome. Twenty-two patients with neurobrucellosis are described. Ten patients had meningoencephalitis, seven patients had meningitis, three patients had polyradiculopathy and one patient presented with spinal epidural abscess and one patient had brain abscess. Results of an agglutination test for Brucella in serum were positive for all patients (>1:160; eight of 15 patients had positive agglutination test in CSF. Five patients had positive blood cultures, 3 patients had positive bone marrow cultures and 2 of 15 patients had positive CSF cultures. All of cultures were Brucella Mellitensis. Antimicrobial treatment included concurrent administration of Doxycycline, Rifampin and Trimethoprim-Sulfametoxazole. Four patients received Dexamethason concurrently. In conclusion, nervous system involvement is a serious manifestation of brucellosis. As brucellosis is an endemic disease in Iran we suggest that brucellosis be investigated with neurological symptoms and signs.

    2016-03-01

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

    Full Text Available Patients involved on coeliac disease (CD have atypical symptoms and often remain undiagnosed. Specific oral manifestations are effective risk indicators of CD and for this reason an early diagnosis with a consequent better prognosis can be performed by the dentist. There are not researches analysing the frequency of these oral manifestations in potential coeliac patients. The aim of this study is to investigate the oral hard and soft tissue lesions in potential and ascertained coeliac children in comparison with healthy controls. 50 ascertained children, 21 potential coeliac patients, and 54 controls were recruited and the oral examination was performed. The overall oral lesions were more frequently present in CD patients than in controls. The prevalence of oral soft tissue lesions was 62% in ascertained coeliac, 76.2% in potential coeliac patients, and 12.96% in controls (P<0.05. Clinical dental delayed eruption was observed in 38% of the ascertained coeliac and 42.5% of the potential coeliac versus 11.11% of the controls (P<0.05. The prevalence of specific enamel defects (SED was 48% in ascertained coeliac and 19% in potential coeliac versus 0% in controls (P<0.05; OR=3.923. The SED seem to be genetically related to the histological damage and villous atrophy.

    The development programmes of different TNF-blocking agents in psoriatic arthritis (PsA) not only provided substantial evidence for the therapeutic benefits of the specific treatment options, but also enabled new insights into the differential treatment effects on distinct disease manifestations. For the first time, specific robust evidence for distinctive effects on different manifestations of PsA, as a distinct entity separate from rheumatoid arthritis (RA), has been generated in a standardized way. The clearest evidence was shown for an effect on peripheral arthritis (polyarticular) with ACR20 response rates from 45 up to 58% (vs. 9-24% for placebo), and an inhibition of radiographic progression demonstrated for the first time for a treatment principle in PsA. However, as PsA does not remain confined to the peripheral joints, it was necessary to address diverse patterns of PsA-subtypes in the outcome measurements of the anti-TNF trials. Accordingly, the results of the clinical studies on anti-TNF treatment also have demonstrated efficacy on enthesitis, dactylitis and skin psoriasis, either in sub analysis of results from phase III RCTs, or in additional prospective studies.

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

    The term 'piriformis syndrome' (PS), introduced by Robinson in 1947, implies a group of signs and symptoms caused by piriformis muscle (PM) disorders. Since PM disorders lead to irritation/compression of the anatomic structures passing under its belly, the main clinical PS signs and symptoms are actually the clinical signs and symptoms of irritation/ compression of neural and vascular structures passing through the infrapiriform foramen: sciatic nerve/SN, inferior gluteal nerve, posterior femoral cutaneous nerve, pudendal nerve, inferior gluteal artery and vein and inferior pudendal artery and vein. The clinical picture is usually dominated by signs and symptoms of irritation/compression of SN (SN irritation --> low back and buttock pain, sciatica,paresthesias in distribution of SN; SN compression --> low back and buttock pain,sciatica, paresthesias and neurologic deficit in distribution of SN). Irritation/compression of other structures can result in the following signs and symptoms: inferior gluteal nerve --> atrophy of gluteal muscles; posterior femoral cutaneous nerve --> pain, paresthesias and sensory disturbances in the posterior thigh; pudendal nerve --> pudendal neuralgia, painful sexual intercourse (dyspareunia), sexual dysfunction, urination and defecation problems; inferior gluteal artery --> ischemic buttock pain; inferior pudendal artery --> ischemic pain in the area of external sex organs, perineum and rectum, sexual dysfunction, urination and defecation problems; inferior gluteal vein --> venous stasis in gluteal area; inferior pudendal vein --> venous stasis in external sex organs and rectum. Functional/non-organic and organic PM disorders can cause PS: spasm, shortening, hypertrophy, anatomic variations, edema, fibrosis, adhesions, hematoma, atrophy, cyst, bursitis, abscess, myositis ossificans, endometriosis, tumors (functional disorders: PM spasm and shortening). The most common causes for PS are PM spasm, shortening and hypertrophy and anatomic

    To assess how accurately computed tomography (CT) can demonstrate the abnormal findings which are believed to cause the clinical signs and symptoms of hearing loss (HL), vertigo and facial paralysis (FP) in patients with temporal bone trauma. The authors studied CT scans of 39 ears in 35 patients with temporal bone trauma. CT scans were performed with 1-1.5 mm slice thickness and table incrementation. Both axial and coronal scans were obtained in 32 patients and in three patients only axial scans were obtained. We analyzed CT with special reference to the structural abnormalities of the external auditory canal, middle ear cavity, bony labyrinth, and facial nerve canal, and correlated these findings with the actual clinical signs and symptoms. As to hearing loss, we evaluated 32 ears in which pure tone audiometry or brainstem evoked response audiometry had been performed. With respect to the specific types of HL, CT accurately showed the abnormalities in 84% (16/19) in conductive HL, 100% (2/2) in sensorineural HL, and 25% (2/8) for mixed HL. When we categorized HL simply as conductive and sensorineural, assuming that mixed be the result of combined conductive and sensorineural HL, CT demonstrated the abnormalities in 89% (24/27) for conductive HL and 50% (5/10) for sensorineural HL. Concerning vertigo and FP, CT demonstrated abnormalities in 67%(4/6), and 29% (4/14), respectively. Except for conductive HL, CT seems to have a variable degree of limitation for the demonstration of the structural abnormalities resulting sensorineural HL, vertigo or facial paralysis. It is imperative to correlate the CT findings with the signs and symptoms in those clinical settings.

    OBJECTIVE A sonographically short cervix is a powerful predictor of spontaneous preterm delivery. However, the etiology and optimal management of a patient with a short cervix in the mid-trimester of pregnancy remain uncertain. Microbial invasion of the amniotic cavity (MIAC) and intra-amniotic inflammation are frequently present in patients with spontaneous preterm labor or acute cervical insufficiency. This study was conducted to determine the rate of MIAC and intra-amniotic inflammation in patients with a cervical length <25 mm in the mid-trimester. STUDY DESIGN A retrospective cohort study was conducted of patients referred to our high risk clinic because of a sonographic short cervix or a history of a previous preterm birth. Amniocenteses were performed for the evaluation of MIAC and for karyotype analysis in patients with a short cervix. Fluid was cultured for aerobic and anaerobic bacteria, as well as genital mycoplasmas. Patients with MIAC were treated with antibiotics selected by their physician. RESULTS Of 152 patients with a short cervix at 14–24 weeks, 57 had amniotic fluid analysis. The prevalence of MIAC was 9% (5/57). Among these patients, the rate of preterm delivery (<32 weeks) was 40% (2/5). Microorganisms isolated from amniotic fluid included Ureaplasma urealyticum (n=4) and Fusobacterium nucleatum (n=1). Patients with a positive culture for Ureaplasma urealyticum received intravenous Azithromycin. Three patients with Ureaplasma urealyticum had a sterile amniotic fluid culture after treatment, and subsequently delivered at term. The patient with Fusobacterium nucleatum developed clinical chorioamnionitis and was induced. CONCLUSION 1) Sub-clinical MIAC was detected in 9% of patients with a sonographically short cervix (<25 mm); and 2) maternal parenteral treatment with antibiotics can eradicate MIAC caused by Ureaplasma urealyticum. This was associated with delivery at term in the three patients whose successful treatment was documented by

    Leucine-rich glioma inactivated 1 (LGI1) was recently identified as a target protein in autoimmune synaptic encephalitis, a rare condition associated with autoantibodies against structures in the neuronal synapse. Studies dealing with LGI1 are small in number and the various outcomes of different therapeutic regimens are not well studied. Here, we analyzed clinical characteristics of 14 patients with LGI1 antibodies, and outcomes according to therapeutic strategies. Most patients exhibited abnormal brain positron emission tomography and that patients treated with steroids alone were more likely to relapse and had less favorable outcomes than those treated with steroids and intravenous immunoglobulins.

    Full Text Available Paroxysmal kinesigenic dyskinesia (PKD is a disorder characterized by recurrent and brief attacks that are induced by sudden voluntary movement with highly clinical and genetic heterogeneity. Familial PKD are mostly autosomal dominant inherited and proline-rich transmembrare protein 2 (PRRT2 gene has been identified as the causative gene for PKD. So far 56 mutations have been documented and most of them are nonsense ones. No obvious genotype-phenotype correlation has been observed and the function of PRRT2 is still unclear, but the interaction between PRRT2 and synaptosomal-associated protein 25 (SNAP25 will shed the light on the research of PKD mechanism.

    The leading cause of morbidity and mortality in patients with acromegaly is cardiovascular complications. Myocardial exposure to excessive growth hormone can cause ventricular hypertrophy, hypertension, arrhythmia, and diastolic dysfunction. However, congestive heart failure as a result of systolic dysfunction is observed only rarely in patients with acromegaly. Most cases of acromegaly exhibit high levels of serum insulin-like growth factor-1 (IGF-1). Acromegaly with normal IGF-1 levels is rare and difficult to diagnose. Here, we report a rare case of an acromegalic patient whose first clinical manifestation was severe congestive heart failure, despite normal IGF-1 levels. We diagnosed acromegaly using a glucose-loading growth hormone suppression test. Cardiac function and myocardial hypertrophy improved 6 months after transsphenoidal resection of a pituitary adenoma.

    The Andersen-Tawil syndrome is a cardiac ion channel disease that is inherited in an autosomal dominant way and is classified as type 7 of the congenital long QT syndromes. Affected gene is KCNJ2, which forms the inward rectifier potassium channel designated Kir2.1. This protein is involved in stabilizing the resting membrane potential and controls the duration of the action potential in skeletal muscle and heart. It also participates in the terminal repolarization phase of the action potential in ventricular myocytes and is a major component responsible for the correction in the potassium current during phase 3 of the action potential repolarization. Kir 2.1 channel has a predominant role in skeletal muscle, heart and brain. Alterations in this channel produce flaccid paralysis, arrhythmias, impaired skeletal development primarily in extremities and facial area. In this review we address the disease from the point of view of clinical and molecular diagnosis with emphasis on cardiac manifestations.

    Full Text Available It’s introduced Lean techniques in a Clinical Laboratory to improve the operability and the efficiency in continuous processes of analysis, failsafe systems, analysis of areas of value pursuit of zero defects and reduction of waste, and it promote continuous improvement in presented difficulties in adapting to the changing needs of the healthcare environment. Whereas it is necessary to incorporate certification and accreditation, note that the adaptability of the clinical laboratory to the changing needs of physicians in obtaining analytical information is reduced. The application of an agile methodology on analytical systems can provide a line of work that allows the incorporation of planning short work cycles on equips quickly with operational autonomy on the basis of demand and respecting the accreditation requirements and flexibility to ensure adequate performance as the intercomparison of results from the different units analytics, analytical quality and turnaround times. Between 2012 and 2014, a process of analysis and improvement was applied to circuits, a 5 s system, transportation of samples, inventory of reactive and samples, motion of personal and samples, reductions of waiting and delays, overproduction, over processing, and defects of results and reports. At last it seems necessary to apply the Agile methodology to adapt to the evolving necessities in time and the different origins of the samples. It’s have used modular systems where the modules of this study are programmed with immunoassay techniques and it has reduced the operative modules depending on the required activity, ensuring the goals of turnaround times, analytic quality, service, health care continuity, and keeping up with the ISO 15189 accreditation requirements. The results of applying the concept of Lean-Agile to a modular system allows us to reduce the associated costs to the seasonal variation of the health care demand and to adapt the system to the changes on

    Systemic lupus erythematosus (SLE) is a nonorgan-specific autoimmune disease which affects multiple organ systems and is multifactorial in etiology. SLE is the prototypic systemic rheumatic disease with immune dysregulation characterized by (1) polyclonal activation of B-cells and (2) production of a large spectrum of autoantibodies with a marked preference for nuclear and intracellular antigens. The clinical and laboratory manifestations and criteria for classification and diagnosis of systemic lupus erythematosus, lupus-like syndromes, and various subsets of systemic lupus erythematosus, are reviewed. The differential diagnosis of SLE and related diseases is described with correlation of specific intracellular autoantibodies.

    The objective of the present study was to clarify the characteristic pathognomonic features of middle ear lesions associated with tuberculosis and the approaches to their diagnostics under the present-day conditions. The study included 11 cases (18 ears) of tuberculosis otitis media and the related lesions of the mastoid process diagnosed with the use of clinical, roentgenological, cytological, bacteriological, pathomorphological, and molecular-genetic methods (including PCR diagnostics). The primary localization of tuberculosis in the middle ear was documented in 6 patients; in 5 patients, it was associated with pulmonary involvement. Five patients presented with smoldering exudative otitis media and the remaining six ones with suppurative perforating otitis media. The tuberculous process was diagnosed with the use of various methods including clinical examination, bacteriological (9%), cytological (27.3%), pathomorphological (18%) studies, and PCR diagnostics (55%). Diagnosis was made within a period from 1 month to 1.5 years after the application of the patients for medical assistance which suggests the difficulty of verification of tuberculous etiology of the disease of the middle ear. It is concluded that the high index of suspicion in the case of smoldering middle ear pathology facilitates its early diagnostics and successful treatment.

    Vitiligo is the most common depigmenting disorder resulting from the loss of melanocytes from the basal epidermal layer. The pathogenesis of the disease is likely multifactorial and involves autoimmune causes, as well as oxidative and mechanical stress. It is important to identify early events in vitiligo to clarify pathogenesis, improve diagnosis, and inform therapy. Here, we show that E-cadherin (Ecad), which mediates the adhesion between melanocytes and keratinocytes in the epidermis, is absent from or discontinuously distributed across melanocyte membranes of vitiligo patients long before clinical lesions appear. This abnormality is associated with the detachment of the melanocytes from the basal to the suprabasal layers in the epidermis. Using human epidermal reconstructed skin and mouse models with normal or defective Ecad expression in melanocytes, we demonstrated that Ecad is required for melanocyte adhesiveness to the basal layer under oxidative and mechanical stress, establishing a link between silent/preclinical, cell-autonomous defects in vitiligo melanocytes and known environmental stressors accelerating disease expression. Our results implicate a primary predisposing skin defect affecting melanocyte adhesiveness that, under stress conditions, leads to disappearance of melanocytes and clinical vitiligo. Melanocyte adhesiveness is thus a potential target for therapy aiming at disease stabilization.

    The most important infectious cause of antibiotic-associated diarrhoea and colitis is Clostridium difficile, which is a Gram-positive, anaerobic, spore-forming, toxin-producing bacillus. In this overview we will discuss the diagnostic and therapeutic management of patients presenting with suspected or proven C. difficile infection (CDI). The clinical spectrum varies from asymptomatic C. difficile carriers to fulminant colitis with multi-organ failure. The onset of symptoms is usually within 2 weeks after initiation of antibiotic treatment. Diagnosis is based on the combination of clinical symptoms and either a positive stool test for C. difficile toxins or endoscopic or histological findings of pseudomembranous colitis. There is no indication for treatment of asymptomatic carriers, but patients with proven CDI should be treated. Treatment consists of cessation of the provoking antibiotic treatment, secondary prevention by infection control strategies, and treatment with metronidazole or vancomycin. Treatment of recurring CDI, severe infection, the need for surgery, and novel alternative potential treatment strategies will be discussed. The concurrent increase in multiresistant colonisation and increasing numbers of asymptomatic carriers of C. difficile will lead to an increase of the situation in which patients with severe infections, treated with broad-spectrum antibiotics, will develop concurrent severe CDI. We will discuss possible therapy strategies for these patients.

    Osteogenesis imperfecta (OI) type V is a specific OI phenotype with interosseous membrane calcification of the forearm and hyperplastic callus formation as typical features. The causative gene mutation for OI type V has been recently discovered. The purpose of this report is to review the clinical and radiographic characteristics of mutation confirmed OI type V in detail. Sixteen (nine familial and seven sporadic) patients were enrolled in the study. Blue sclera and dentinogenesis imperfecta were not evident in any patient. However, hypodontia in the permanent teeth, ectopic eruption, and short roots in molars were additionally observed in 11 patients. Of the radiographic abnormalities, cortical thickening and bony excrescence of interosseous margin of the ulna was the most common finding, followed by overgrowth of the olecranon and/or coronoid process of the ulna. Slender ribs and sloping of the posterior ribs with or without fractures were also a consistent finding. Hyperplastic callus was detected in 75% of patients and was commonly encountered at the femur. Heterotopic ossification in the muscles and tendon insertion sites were noted in four patients, which resulted in bony ankylosis or contracture of joints. The current study confirms common clinical and radiographic findings of OI type V and reports additional phenotypic information. These observations provide clues to recognize OI type V more promptly and guide to direct targeted molecular study. © 2013 Wiley Periodicals, Inc.

    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.

    Of the various genetic homologues to Duchenne Muscular Dystrophy (DMD), the Golden Retriever Muscular Dystrophy (GRMD) dog, which presents a variable but usually severe and progressive muscle weakness, has the closest relevance to DMD in both clinical severity and histopathological change. Among 77 GRMD dogs born in our colony in Brazil, we have identified a very mildly affected dog, Ringo, born July 2003. Among his descendants, at least one male, Suflair, is also showing a mild course. In an attempt to better characterize these two dogs, we studied the pattern of muscle proteins expression in Ringo and Suflair, as compared to severely affected and normal control dogs. Dystrophin was absent in both and utrophin was overexpressed in a pattern similar to the observed in severely affected dogs. Understanding the mechanism that is protecting Ringo and Suflair from the deleterious effect of the dystrophin gene mutation is of utmost interest. In addition it points out that the clinical impact of therapeutic trials should be interpreted with caution.

    The purpose of this task force was to critically analyze nine non-criteria manifestations of APS to support their inclusion as APS classification criteria. The Task Force Members selected the non-criteria clinical manifestations according to their clinical relevance, that is, the patient-important outcome from clinician perspective. They included superficial vein thrombosis, thrombocytopenia, renal microangiopathy, heart valve disease, livedo reticularis, migraine, chorea, seizures and myelitis, which were reviewed by this International Task Force collaboration, in addition to the seronegative APS (SN-APS). GRADE system was used to evaluate the quality of evidence of medical literature of each selected item. This critical appraisal exercise aimed to support the debate regarding the clinical picture of APS. We found that the overall GRADE analysis was very low for migraine and seizures, low for superficial venous thrombosis, thrombocytopenia, chorea, longitudinal myelitis and the so-called seronegative APS and moderate for APS nephropathy, heart valve lesions and livedo reticularis. The next step can be a critical redefinition of an APS gold standard, for instance derived from the APS ACTION registry that will include not only current APS patients but also those with antiphospholipid antibodies not meeting current classification criteria.

    Full Text Available OBJECTIVES: To characterize the clinical, laboratory, and anthropometric profile of a sample of Brazilian patients with glycogen storage disease type I managed at an outpatient referral clinic for inborn errors of metabolism. METHODS: This was a cross-sectional outpatient study based on a convenience sampling strategy. Data on diagnosis, management, anthropometric parameters, and follow-up were assessed. RESULTS: Twenty-one patients were included (median age 10 years, range 1-25 years, all using uncooked cornstarch therapy. Median age at diagnosis was 7 months (range, 1-132 months, and 19 patients underwent liver biopsy for diagnostic confirmation. Overweight, short stature, hepatomegaly, and liver nodules were present in 16 of 21, four of 21, nine of 14, and three of 14 patients, respectively. A correlation was found between height-for-age and BMI-for-age Z-scores (r = 0.561; p = 0.008. CONCLUSIONS: Diagnosis of glycogen storage disease type I is delayed in Brazil. Most patients undergo liver biopsy for diagnostic confirmation, even though the combination of a characteristic clinical presentation and molecular methods can provide a definitive diagnosis in a less invasive manner. Obesity is a side effect of cornstarch therapy, and appears to be associated with growth in these patients.

    Full Text Available We have previously shown that overweight may increase the risk of developing rheumatoid arthritis (RA in autoantibody positive individuals. Adipose tissue could contribute to the development of RA by production of various bioactive peptides. Therefore, we examined levels of adipokines in serum and synovial tissue of subjects at risk of RA.Fifty-one individuals positive for immunoglobulin M rheumatoid factor (IgM-RF and/or anti-citrullinated protein antibodies (ACPA, without arthritis, were included in this prospective study. Levels of adiponectin, vaspin, resistin, leptin, chemerin and omentin were determined in baseline fasting serum samples (n = 27. Synovial tissue was obtained by arthroscopy at baseline and we examined the expression of adiponectin, resistin and visfatin by immunohistochemistry.The development of clinically manifest arthritis after follow-up was associated with baseline serum vaspin levels (HR1.5 (95% CI 1.1 to 2.2; p = 0.020, also after adjustment for overweight (HR1.7 (95% CI 1.1 to 2.5; p = 0.016. This association was not seen for other adipokines. Various serum adipokine levels correlated with BMI (adiponectin r = -0.538, leptin r = 0.664; chemerin r = 0.529 and systemic markers of inflammation such as CRP levels at baseline (adiponectin r = -0.449, omentin r = -0.557, leptin r = 0.635, chemerin r = 0.619, resistin r = 0.520 and ESR (leptin r = 0.512, chemerin r = 0.708, p-value<0.05. Synovial expression of adiponectin, resistin and visfatin was not associated with development of clinically manifest arthritis.In this exploratory study, serum adipokines were associated with an increased inflammatory state in autoantibody-positive individuals at risk of developing RA. Furthermore, serum vaspin levels may assist in predicting the development of arthritis in these individuals.

    Background. Metabolic and genetic factors induce plasminogen activator inhibitor type-1 (PAI-1) overexpression; higher PAI-1 levels decrease fibrinolysis and promote atherothrombosis. Aim. To assess PAI-1 antigen levels among subjects with type 2 diabetes mellitus (T2DM) plus Metabolic Syndrome (MetS) before clinical manifestations of atherothrombosis and the contribution of metabolic factors and 4G/5G polymorphism of PAI-1 gene on the variability of PAI-1. Methods. We conducted an observational, cross-sectional assay in a hospital in Mexico City from May 2010 to September 2011. MetS was defined by the International Diabetes Federation criteria. PAI-1 levels and 4G/5G polymorphism were determined by ELISA and PCR-RFLP analysis. Results. We enrolled 215 subjects with T2DM plus MetS and 307 controls. Subjects with T2DM plus MetS had higher PAI-1 levels than the reference group (58.4 ± 21 versus 49.9 ± 16 ng/mL, p = 0.026). A model with components of MetS explained only 12% of variability on PAI-1 levels (R2 = 0.12; p = 0.001), with β = 0.18 (p = 0.03) for hypertension, β = −0.16 (p = 0.05) for NL HDL-c, and β = 0.15 (p = 0.05) for NL triglycerides. Conclusion. Subjects with T2DM plus MetS have elevated PAI-1 levels before clinical manifestations of atherothrombotic disease. Metabolic factors have a more important contribution than 4G/5G polymorphism on PAI-1 plasma variability. PMID:28271069

    Full Text Available Background and purpose: Chronic abdominal pain is a common clinical problem in children. Apleys reported the incidence of 10-15% of chronic abdominal pain in school age children, but recent studies reported 20% of that type of pain. The aim of this study was determining the spectrum of clinical manifestations of dyspeptic children and to identify the relation between some clinical symptoms, organic or functional dyspepsia, and long term follow up of functional type.Materials and Methods: This descriptive case series study was done on 232 children between 4 and 18 years of age complaining about chronic abdominal pain chiefly who had referred to pediatric gastroenterology department of Boo-Ali Hospital of sari in 2005-2006. A checklist composed of patient demographic criteria and pain characteristics was prepared. Physical exam and laboratory tests such as AST, ALT, U/A, U/C, S/E, ESR, CBC were performed for all patients. If there were any alarming signs of organic abdominal pain-persistence or recurrence of symptoms and severe disability despite the use of H-blockers-upper GI endoscopies was indicated. Recorded data were analyzed by SPSS software and Chi- square tests.Results: 102 of 232 patients had dyspepsia; 59 were girls (9.2y/o, and 43 were boys (7.5y/o. 65 out of 102 patients had dominant abdominal pain and the rest had flatulence, vomiting and early fullness. 64 of them went under UGI endoscopies. 28 of 64 had mucosal erosion.Conclusion: Because the functional or organic abdominal pain has not unique diagnostic criteria, and the data about pathological change in children are fewer than that of adults we recommend the clinical findings and biochemical change of mucosa for differential diagnosis in children.

    GVHD is one of the most frequent complications of BMT and recently nephrotic syndrome (NS) has been described as a manifestation of chronic GVHD. Here, we present an AA patient who developed NS 1 year after BMT when cyclosporine was stopped. Renal biopsy showed focal sclerosis associated with membranous deposits. He also had other clinical manifestations of chronic GVHD: sicca-like syndrome and colestasis. After 15 days of CsA therapy, he experienced a remarkable improvement in the NS and GVHD as a whole. We comment on immunological mechanisms that could be involved in the pathogenesis of this manifestation.

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

    We report on a large Brazilian kindred with young-onset parkinsonism due to either a homozygous or heterozygous mutation in parkin. A total of 6 members were affected: 5 were homozygous and 1 heterozygous for a deletion in exon 4. Two other heterozygotes also had extrapyramidal signs. All affected subjects showed characteristic features of parkin disease with foot dystonia and an excellent response to levodopa complicated by motor fluctuations and dyskinesia within 3 years of therapy. Careful clinical follow-up over 10 years showed the phenotype was similar in all the homozygotes with asymmetrical limb bradykinesia and early walking difficulties. Some acceleration of disability was observed in some of the cases as they entered the third decade of illness, but dementia was absent.

The aim of this study was to construct a diagnostic support system for DDH based on clinical findings obtained from the X-ray images of 154 female infants with confirmed diagnoses made by orthopedists. The data for these subjects were divided into 2 groups. The Min-Max method of nonlinear analysis was applied to the data from Group 1 to construct the diagnostic support system based on the measurement of 4 items in X-ray images:the outward displacement rate, upward displacement rate, OE angle, and alpha angle. This system was then applied to the data from Group 2, and the results were compared between the 2 groups to verify the reliability of the system. We obtained good results that matched the confirmed diagnoses of orthopedists with an accuracy of 85.9%.

    OBJECTIVE: We report an extremely rare case of extramedullary plasmacytoma. METHOD: Case report and review of the English-literature concerning extramedullary plasmacytoma and multiple myeloma. RESULT: We present an unusual case of multiple extramedullary plasmacytomas, which, over a protracted course of 30 years, presented on different occasions at three separate sites in the head and neck. The patient was managed surgically on all occasions, and was disease-free at the time of writing. CONCLUSION: Following review of the literature, we believe this to be the only case with this extremely unusual presentation. This case is noteworthy, not only because of the rarity of extramedullary plasmacytoma, but also because it highlights a number of important clinical issues. The diagnosis and management of extramedullary plasmacytoma require close cooperation between multiple disciplines.

    Full Text Available Eosinophilic granuloma is a variety of Histiocytosis-X. Its etio-logy is unknown. When it involves the temporal bone it may mimic chronic otitis media, or a mastoid abscess, very often leading to an erroneous diagnosis. Its X-ray appearance and histopathology are characteristic. Infiltration with eosinophils and histiocytes is a constant feature. Very good results are achieved with surgery accompanied by radiotherapy. In this series of 3 patients, one pa-tient presented with facial paralysis and another one with bilateral post-auricular swellings. The first 2 cases were diagnosed only after surgery and histopathological examination of the tissue removed, while the third case was diagnosed pre-operatively on clinical and radiological findings.

    Blastocystis is a human common enteric protist that may colonize a large variety of non-human hosts linked to symptoms and diseases such as abdominal pain, constipation, diarrhea, urticaria, flatulence and irritable bowel syndrome (IBS). Blastocystis exhibits remarkable genetic diversity and multiple subtypes (STs) within the genus with no absolute associations with clinical symptomatology. Here we analyzed fecal samples from Argentinean patients (n=270) belonging to symptomatic (urticaria and non-specific gastrointestinal symptoms, n=39) and asymptomatic control (n=28). Those patients infected with Blastocystis (n=67) were submitted for morphological analysis, DNA extraction, 18S PCR, sequencing and STs identification according to DNA barcoding. Blastocystis vacuolar forms were the predominant morphotype (75%), ameboid-like forms were evidenced in 1.5% of samples. Blastocystis ST3 was detected in 71.6% (n=48), of which 71.4%, (n=35) and 28.6% (n=14) belonged to symptomatic and asymptomatic respectively. Other subtypes identified were ST1 (14.9%), ST6 (7.5%) and ST2 (5.9%). Blastocystis 18S barcoding evidenced in non-urticaria symptomatic patients and asymptomatic control group the presence of allele 134 (ST3) (p<0.0001), while allele 34 (ST3) was detected in 85.7% (18/21) of symptomatic uricaria as compared with control group (1/21) (p<0.0001). The presence of a particular allele (a34) significantly associated with urticaria patients was detected and the clinical implications of these findings are herein discussed.

    Coenzyme Q(10) is a remarkable lipid involved in many cellular processes such as energy production through the mitochondrial respiratory chain (RC), beta-oxidation of fatty acids, and pyrimidine biosynthesis, but it is also one of the main cellular antioxidants. Its biosynthesis is still incompletely characterized and requires at least 15 genes. Mutations in eight of them (PDSS1, PDSS2, COQ2, COQ4, COQ6, ADCK3, ADCK4, and COQ9) cause primary CoQ(10) deficiency, a heterogeneous group of disorders with variable age of onset (from birth to the seventh decade) and associated clinical phenotypes, ranging from a fatal multisystem disease to isolated steroid resistant nephrotic syndrome (SRNS) or isolated central nervous system disease. The pathogenesis is complex and related to the different functions of CoQ(10). It involves defective ATP production and oxidative stress, but also an impairment of pyrimidine biosynthesis and increased apoptosis. CoQ(10) deficiency can also be observed in patients with defects unrelated to CoQ(10) biosynthesis, such as RC defects, multiple acyl-CoA dehydrogenase deficiency, and ataxia and oculomotor apraxia.Patients with both primary and secondary deficiencies benefit from high-dose oral supplementation with CoQ(10). In primary forms treatment can stop the progression of both SRNS and encephalopathy, hence the critical importance of a prompt diagnosis. Treatment may be beneficial also for secondary forms, although with less striking results.In this review we will focus on CoQ(10) biosynthesis in humans, on the genetic defects and the specific clinical phenotypes associated with CoQ(10) deficiency, and on the diagnostic strategies for these conditions.

    The hepatic consequences of an infection with the hepatitis C virus (HCV) are well recognised, but extrahepatic manifestations of HCV may be just as severe. Here we have reviewed various extrahepatic manifestations of HCV such as mixed cryoglobulinemia, lymphoma, metabolic features and neurologic consequences and we discuss pathogenesis and management of these clinical problems. We concluded with important aspects of therapy with novel anti-HCV agents and its effects on extrahepatic manifestations.

    Sheehan's syndrome is characterized by hypopituitarism that occurs as a result of ischemic pituitary necrosis due to severe postpartum hemorrhage. Nowadays it is not usually seen in developed countries because of the improvements in obstetric care. However, in developing countries it is still frequent and probably one of the most common causes of hypopituitarism. Most patients usually present it months to years later, with a history of failure of postpartum lactation, failure to resume menses and other signs of panhypopituitarism. In mild forms of the disease, patients may remain undetected and do not receive treatment for many years. Early diagnosis and appropriate treatment are important to reduce the morbimortality of the patients with Sheehan's syndrome. The aim of this review is to describe clinical, laboratory and therapeutic aspects of Sheehan's syndrome, including our experience in the replacement of recombinant GH in these patients.

    Understanding the biologic systems that underlie the relationship between stress and alcohol consumption may lead to better prevention efforts and more effective treatments for alcoholism. Clinical laboratory studies offer a unique opportunity to examine these relationships by using a controlled environment to study how an acute stressor affects alcohol drinking and alcohol craving, how individuals in recovery or those at risk for alcoholism may respond differently to stressors relative to control subjects, and how alcohol differentially affects stress reactivity in these groups. This article reviews some of the most common physical, psychological, and pharmacological stressors used in stress-induction studies designed to reveal details about the relationship between stress reactivity and alcohol use and abuse.

    The exact mechanism for the occurrence of sickle leg ulcers (SLUs) has not been fully explained, although, popular opinion supports a multifactorial etio-pathogenetic process. Leg ulceration in sickle cell is a chronic and debilitating condition which is difficult to treat and may worsen the psychosocial impact of this illness. This study aims to evaluate the laboratory and clinical correlates of SLUs. One hundred sixty-seven patients who had been diagnosed with sickle cell anemia (homozygous S) had their steady-state hemoglobin concentration (Hb), hematocrit, white cell count, platelet count, serum bilirubin, and aspartate transaminase (AST) as well as frequency of crisis per annum evaluated with respect to their relationship to the occurrence of leg ulcers. They were aged 6-53 years (mean age 24.3 years), and prevalence of leg ulcer was found to be 2.75 per 1000 (2.54 per 1000 in females and 2.83 per 1000 in males). The independent sample t-test showed a significant difference in the serum AST levels in those with SLU (p = 0.029), though a positive correlation did not exist. Other predictors of disease severity found to have positive relationship with each other were the AST and total serum bilirubin 0.207 (p = 0.012); Hb and age 0.130 (p = 0.035); Hb and white cell count -0.159 (p = 0.010), white cell count and age -0.113 (p = 0.018). SLUs do not occur in patients with severe disease in sickle cell. The clinical and laboratory indicators of severe sickle cell disease do not correlate positively with the occurrence of SLU. Serum AST may have a relationship with leg ulceration in these patients. Environmental factors most likely play a major part in the etiopathogenesis of leg ulcer and this may require further studies in different sociocultural settings.

  7. Amalgam tattoo (amalgam pigmentation) of the oral mucosa: clinical manifestations, diagnosis and treatment.

    2004-07-01

    Amalgam tattoo is an iatrogenic lesion caused by traumatic implantation of dental amalgam into soft tissue. Amalgam tattoo is the most common localized pigmented lesion in the mouth. In a study of a mass screening oral examination in the United States, it was found in about 0.4-0.9% of the adult population and in Sweden in about 8%. Clinically, amalgam tattoo presents as a dark gray or blue, flat macule located adjacent to a restored tooth. Most are located on the gingiva and alveolar mucosa followed by the buccal mucosa and the floor of the mouth. Microscopic examination reveals that amalgam is present in the tissues in two forms: as irregular dark, solid fragments of metal or as numerous, discrete fine, brown or black granules dispersed along collagen bundles and around small blood vessels and nerves. In most lesions, it is presented in both forms. The biologic response to the amalgam is related to particle size, quantity and elemental composition of the amalgam. Large fragments often become surrounded by dense fibrous connective tissue. Smaller particles are associated with mild to moderate chronic inflammatory response with individual macrophages engulfing small amalgam particles. Occasionally, the reaction takes the form of foreign body granuloma in which macrophages and multinucleated giant cells are present. Some of the multinucleated giant cells also contain amalgam particles. Diagnosis of amalgam tattoo is usually obvious from the location and clinical appearance. A radiograph is recommended to confirm the presence of metallic particles, but absence of radiographic evidence does not rule out the possibility, since particles are often too fine or widely dispersed to be visible on radiographs. When there is no radiographic evidence or an adjacent restored tooth, biopsy is recommended to rule out an early melanoma. Once the diagnosis of amalgam tattoo has been established, no additional treatment is necessary except for cosmetic reasons. If the pigmentation

    Full Text Available The paper considers a case of adult-onset Still's disease that occurred as acute pericarditis, two-spike hectic fever, and neutrophilic leukocytosis in a young man. It was difficult to establish a correct diagnosis because there were no characteristic clinical symptoms of Still's disease, such as salmon colored rash, arthralgia, and sore throat. The diagnosis of adult-onset Still's disease was verified on the basis of the classification criteria described by M. Yamaguchi et al. The special feature of the clinical case was the development of steroid resistance and the effective use of a combination of the interleukin-6 receptor blocker tocilizumab (8 mg/kg body weight, given intravenously dropwise once every four weeks and methotrexate (15 mg/week orally. During this treatment, a sustained clinical and laboratory response was achieved, which could reduce the dose of glucocorticoids to the maintaining one.

  9. The epidemiology and clinical manifestations of dysexecutive syndrome in Parkinson’s disease

    2012-11-01

    Full Text Available This mini-review summarizes the evidence of the cognitive and behavioural features of dysexecutive syndrome in Parkinson’s disease (PD. Deficits in response inhibition, set-shifting, mental flexibility and strategy have been frequently described from the earliest stages of PD, although there are inconsistencies in study findings due to the complexity of the executive function (EF construct and methodological limitations. Behavioural disorders of PD, e.g. apathy, distractibility, perseverative behaviour and impulse-control disorders, may be viewed as the other side of dysexecutive syndrome. Despite the interrelationship between the cognitive and behavioural domains, some reports reveal that the two syndromes may be dissociated, suggesting that both aspects must be clinically assessed. EFs are widely associated with the prefrontal areas, although dysexecutive syndrome may be observed in patients with damage to other brain regions. EFs drive numerous abilities essential to daily life, such as prospective remembering and language comprehension, which may be impaired in PD subjects. Considering the impact of dysexecutive syndrome on independence and quality of life, early detection of executive impairment is crucial in the management of PD.

    The study aimed to identify the clinical characteristics of coexisting chronic lymphocytic thyroiditis (CLT) in papillary thyroid carcinoma (PTC) and to evaluate the influence on prognosis. A total of 1,357 patients who underwent thyroid surgery for PTC were included. The clinicopathological characteristics were identified. Patients who underwent total thyroidectomy (n = 597) were studied to evaluate the influence of coexistent CLT on prognosis. Among the total 1,357 patients, 359 (26.5%) had coexistent CLT. In the CLT group, the prevalence of females was higher than in the control group without CLT (P < 0.001). Mean tumor size and mean age in the patients with CLT were smaller than without CLT (P = 0.040, P = 0.047, respectively). Extrathyroidal extension in the patients with CLT was significantly lower than without CLT (P = 0.016). Among the subset of 597 patients, disease-free survival rate in the patients with CLT was significantly higher than without CLT (P = 0.042). However, the multivariate analysis did not reveal a negative association between CLT coexistence and recurrence. Patients with CLT display a greater female preponderance, smaller size, younger and lower extrathyroidal extension. CLT is not a significant independent negative predictive factor for recurrence, although presence of CLT indicates a reduced risk of recurrence.

    Full Text Available Epstein-Barr virus (EBV, or human herpesvirus 4 (HHV-4, infects the vast majority of adults worldwide, and establishes both nonproductive (latent and productive (lytic infections. Host immune responses directed against both the lytic and latent cycle-associated EBV antigens induce a diversity of clinical symptoms in patients with chronic active EBV infections who usually contain an oligoclonal pool of EBV-infected lymphocyte subsets in their blood. Episomal EBV genes in the latent infection utilize an array of evasion strategies from host immune responses: the minimized expression of EBV antigens targeted by host cytotoxic T lymphocytes (CTLs, the down-regulation of cell adhesion molecule expression, and the release of virokines to inhibit the host CTLs. The oncogenic role of latent EBV infection is not yet fully understood, but latent membrane proteins (LMPs expressed during the latency cycle have essential biological properties leading to cellular gene expression and immortalization, and EBV-encoded gene products such as viral interleukin-10 (vIL-10 and bcl-2 homologue function to survive the EBV-infected cells. The subsequent oncogenic DNA damage may lead to the development of neoplasms. EBV-associated NK/T cell lymphoproliferative disorders are prevalent in Asia, but quite rare in Western countries. The genetic immunological background, therefore, is closely linked to the development of EBV-associated neoplasms.

    Full Text Available Abstract Aim Clinical and molecular cytogenetic investigations of a newborn girl exhibiting facial dysmorphism with developmental delay. Methods Phenotypic evaluation was first applied to examine the proband's developmental status. Computed tomography and colour transcranial Doppler were used then to investigate her brain structure and function. Subsequently, chromosomal abnormalities were examined by karyotyping and fluorescent in situ hybridization was performed to investigate size of fragments lost at the two distal ends of the ring chromosome 7. In addition, multicolour banding was applied to rule out structural rearrangement occurs in between the ring chromosome 7. Results The proband was born with mosaic supernumerary ring chromosome 7, without a normal karyotype detected in the peripheral blood lymphocytes. The distal arm of chromosome 7p (at least 255 kb from the telomere was part of an extra ring chromosome 7. In addition, the distal arm of 7q, at least 8 kb from the telomere, was missing. There was no other chromosomal rearrangement detected by multicolour banding. Interpretation This is the 19th reported case of complete ring chromosome 7 mosaicism and the first survived case with mosaic supernumerary ring 7 without a normal karyotype detected in the peripheral lymphocytes.

    A retrospective study was performed to investigate the clinical and radiological results of the Sauvé-Kapandji (S-K) procedure for the rheumatoid wrist. One hundred and eight rheumatoid wrists in 98 patients were operated on in our institute from 1992 to 2000, and in 82 wrists we used the S-K procedure. In other cases, synovectomy alone was performed on 16 wrists, and partial and total arthrodeses were performed concurrently on 5 wrists each. Carpal bones and/or radiocarpal joints in which the union could not be assessed radiologically were found in 49 wrists (59.8%) after the S-K procedure, and among them there was definite non-fusion of the carpal bone and radiocarpal joints in 29 wrists (35.4%). However, definite fusion of carpal bones and/or radiocarpal joints was found in 33 wrists (40.2%). The formation of carpal bones and partial radiocarpal fusion with some mobility was detected in some cases. Therefore, the S-K procedure may stabilize the carpus in the rheumatoid wrist to some extent while maintaining a functionally important range of motion and relieving pain. However, it does not stop the disease process and cannot reestablish or maintain carpal height. We concluded that the S-K procedure is the treatment of choice for the rheumatoid wrist, and if the wrist is unstable, as seen with arthritis mutilans, we then perform either radio-lunate partial arthrodesis or total wrist arthrodesis.

    In a 12-month period, metastatic cancer was diagnosed in eight patients. Six of them presented with pain mimicking toothache, temporomandibular joint disorders or trigeminal neuralgia, while two showed osteopenic bone lesions in the panoramic radiography, and perimandibular swelling. Anesthesia of the lower lip was the only common clinical feature. In seven of the eight patients, a whole body bone scintigraphy and single photon emission computed tomography (SPECT) of the skull in combination with a whole body and SPECT anti-granulocyte (Tc-99m MAK 250/183) bone marrow scintigraphy was performed. One patient did not have combined scintigraphy performed secondary to severe systemic illness. In six of the seven, the results were conclusive for a metastatic bone lesion. Biopsies confirmed three patients to have a previously unrecognized primary cancer, one patient to have previously unrecognized recurrent cancer, and three patients to exhibit new metastatic spread of an already diagnosed cancer. Histology revealed breast, lung, renal cancer and a malignancy of inconclusive origin. In the remaining patient, combined scintigraphy suggested osteomyelitis, yet biopsy revealed a prostate cancer metastasis with acute inflammatory cell infiltration. Thus, the scintigraphy pattern of a hot spot in the bone scan and a cold lesion in the bone marrow scintigraphy is highly suggestive of a mandibular metastasis, if accompanied by anesthesia of the lower lip.

    Full Text Available Introduction. Non-Hodgkin lymphoma (NHL is the most frequent malignancy associated with primary immune deficiency disease (PID. We aimed to present the clinical characteristics and outcomes of Belarusian children with PID who developed NHL. Procedure. We reviewed 16 patients with PID and NHL. Eight patients had combined PID: 5—Nijmegen breakage syndrome, 1—Bloom syndrome, 1—Wiskott-Aldrich syndrome, and 1—Х-linked lymphoproliferative syndrome. Results. In 75% cases PID was diagnosed simultaneously or after the NHL was confirmed. PID-associated NHL accounted for 5.7% of all NHL and was characterized by younger median age (6.3 versus 10.0 years, P<0.05 and by prevalence of large-cell types (68.8% versus 24.5%, P<0.001. Children with combined PID had median age of 1.3 years; 5 of them developed EBV-associated diffuse large B-cell lymphoma with lung involvement. Five of 6 patients with chromosomal breakage syndrome developed T-NHL. Six patients died of infections; two died after tumor progression; one child had early relapse; two died of second NHL and one of secondary hemophagocytic syndrome. Overall, 4 children are alive and disease-free after a follow-up from 1.4 to 5.7 years. Conclusions. PID needs to be diagnosed early. Individualized chemotherapy, comprehensive supportive treatment, and hematopoietic stem cell transplantation may improve survival of children with PID and NHL.

    Full Text Available This study is conducted to investigate the clinical characteristics of patients with bacteremia caused by Aeromonas species.Patients with bacteremia caused by Aeromonas species during the period 2009 to 2013 were identified from a computerized database of a regional hospital in southern Taiwan. The medical records of these patients were retrospectively reviewed.A total of 91 patients with bacteremia due to Aeromonas species were identified. In addition to 16 (17.6% primary bacteremia, the most common source of secondary infection is peritonitis (n = 27, 29.7%, followed by biliary tract infection (n = 18, 19.8%, and SSTI (n = 12, 13.2%, pneumonia (n = 9, 9.9%, catheter-related bloodstream infection (n =  5, 5.5%, and genitourinary tract infection (n = 4, 4.4%. A. hydrophila (n = 35, 38.5% was the most common pathogen, followed by A. veronii biovar sobria (n = 31, 34.1%, A. caviae (n = 14, 15.4%, and A. veronii biovar veronii (n = 9, 9.9%. Forty-three (47.3% patients were classified as healthcare-associated infections (HCAI causes by Aeromonas species, and patients with HCAI were more likely to have cancer, and receive immunosuppressant than patients with community-acquired bacteremia. The overall outcomes, including rate of ICU admission, acute respiratory failure, and mortality were 33.3%, 28.6%, and 23.1%, respectively. Multivariate analysis showed that the in-hospital day mortality was significantly associated only with underlying cancer (P <.001, and initial shock (P <.001.Aeromonas species should be considered one of the causative pathogens of healthcare-associated bacteremia, especially in immunocompromised patients. In addition, it can be associated with high fatality. Cancer and initial shock were the poor prognostic factors.

    Alternating hemiplegia of childhood (AHC) is a rare neurodevelopmental disorder characterized by early-onset recurrent distinctive hemiplegic episodes commonly accompanied by other paroxysmal features and developmental impairment. De novo mutations in ATP1A3 were recently identified as a genetic cause of AHC. To describe the entire Danish cohort of paediatric AHC patients we approached neuropaediatricians nationwide. All currently acknowledged Danish patients ≤16 years with AHC were genetically tested and seen by the same child neurologist (PU). Ten patients; seven girls and three boys were identified. Mean present age was 10.0 years (range 1-16). Mean age at presentation was 7.4 months (range 1-18 months). Sequencing of ATP1A3 in all ten patients revealed a pathogenic mutation in seven. Two females with moderate psychomotor impairment were heterozygous for the known p.G947R mutation, whereas one severely retarded boy was heterozygous for the common p.E815K mutation. The prevalent p.D801N mutation was identified in two moderate to severely retarded children. Interestingly, in a set of monochorionic male twins a novel p.D801E mutation was identified, underscoring that the asparagine at position 801 is a mutation hotspot. Three girls aged 5-13 years did not reveal any ATP1A3 mutations. They were rather mildly clinically affected and displayed a normal or near-normal psychomotor development. This is the first study of AHC in the Danish paediatric population. The patients harboured a wide range of psychomotor difficulties. Patients with no mutation detected tended to be less severely affected. Prevalence was approximately 1 per 100,000 children.

    Nevoid basal cell carcinoma syndrome (NBCC; Gorlin syndrome), an autosomal dominant disorder linked to 9q22.3-q31, and caused by mutations in PTC, the human homologue of the Drosophila patched gene, comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies and calcification of the falx cerebri. We reviewed the findings on 105 affected individuals examined at the NIH since 1985. The data included 48 males and 57 females ranging in age from 4 months to 87 years. Eighty percent of whites (71/90) and 38% (5/13) of African-Americans had at least one basal cell carcinoma (BCC), with the first tumor occurring at a mean age of 23 (median 20) years and 21 (median 20) years, respectively. Excluding individuals exposed to radiation therapy, the number of BCCs ranged from 1 to >1,000 (median 8) and 1 to 3 (median 2), respectively, in the 2 groups. Jaw cysts occurred in 78/105 (74%) with the first tumor occurring in 80% by the age of 20 years. The number of total jaw cysts ranged from 1 to 28 (median 3). Palmar pits and plantar pits were seen in 87%. Ovarian fibromas were diagnosed by ultrasound in 9/52 (17%) at a mean age of 30 years. Medulloblastoma occurred in 4 patients at a mean age of 2.3 years. Three patients had cleft lip or palate. Physical findings include {open_quotes}coarse face{close_quotes} in 54%, relative macrocephaly in 50%, hypertelorism in 42%, frontal bossing in 27%, pectus deformity in 13%, and Sprengel deformity in 11%.

    Full Text Available In-house software development for use in a clinical laboratory is a controversial issue. Many of the objections raised are based on outdated software development practices, an exaggeration of the risks involved, and an underestimation of the benefits that can be realized. Buy versus build analyses typically do not consider total costs of ownership, and unfortunately decisions are often made by people who are not directly affected by the workflow obstacles or benefits that result from those decisions. We have been developing custom software for clinical use for over a decade, and this article presents our perspective on this practice. A complete analysis of the decision to develop or purchase must ultimately examine how the end result will mesh with the departmental workflow, and custom-developed solutions typically can have the greater positive impact on efficiency and productivity, substantially altering the decision balance sheet. Involving the end-users in preparation of the functional specifications is crucial to the success of the process. A large development team is not needed, and even a single programmer can develop significant solutions. Many of the risks associated with custom development can be mitigated by a well-structured development process, use of open-source tools, and embracing an agile development philosophy. In-house solutions have the significant advantage of being adaptable to changing departmental needs, contributing to efficient and higher quality patient care.

    Generalized epilepsy with febrile seizures plus (GEFS+) is a childhood genetic epilepsy syndrome. GEFS+ includes a wide spectrum of clinical manifestations, and SCN1A mutations have frequently been reported among the GEFS+-related gene abnormalities. In this study, to clarify the distributions of the clinical subtypes, we analyzed 34 families with GEFS+ in Indonesia using the hospital records of the patients and questionnaires for the family members. The number of patients with febrile seizures plus (FS+), FS+ and afebrile generalized/partial seizures, borderline severe myoclonic epilepsy in infancy (SMEB) and severe myoclonic epilepsy in infancy (SMEI) were 9, 11, 7, and 7, respectively. Most patients had a family history of febrile seizures. Next, we performed molecular analyses to clarify the contributions of SCN1A mutations to the development of the GEFS+ subtypes. Only 3 of 34 probands showed SCN1A mutations. These mutations were two missense mutations, p.V1612I and p.C1756G, in two patients with SMEI and SMEB, and one silent mutation, p.G1762G, in a patient with FS+ and afebrile partial seizures. In conclusion, the majority of GEFS+ patients in Indonesia were not associated with SCN1A mutations. To detect the GEFS+-causing mutations, we must search and analyze other genes in these patients.

    The virulence of Soromba-R, a Lassa virus strain recently isolated from southern Mali, was assessed in 2 animal models of Lassa fever: inbred strain 13 guinea pigs and cynomolgus macaques. In both models, the Malian isolate demonstrated tissue tropism and viral titers similar to those of historical Lassa virus isolates from Sierra Leone (Josiah) and Liberia (Z-132); however, the Soromba-R isolate was found to be less pathogenic, as determined by decreased mortality and prolonged time to euthanasia in macaques. Interestingly, in addition to the classic indicators of Lassa fever, Soromba-R infection presented with moderate to severe pulmonary manifestations in the macaque model. Analysis of host responses demonstrated increased immune activation in Soromba-R-infected macaques, particularly in neutrophil-activating or -potentiating proinflammatory cytokines or growth factors, including tumor necrosis factor α, macrophage inflammatory protein 1α, interleukin 1β, and granulocyte colony-stimulating factor, as well as interleukin 5, which may be responsible for the decreased lethality and uncharacteristic clinical presentation. These results suggest that the strain of Lassa virus circulating in Mali might be less pathogenic than strains circulating in the historical region of endemicity and may result in an atypical presentation for Lassa fever, which could complicate clinical diagnosis.

    The scope of clinical and laboratory manifestations of the antiphospholipid syndrome (APS) has increased dramatically since its discovery in 1983, where any organ system can be involved. Musculoskeletal complications are consistently reported in APS patients, not only causing morbidity and mortality, but also affecting their quality of life. We reviewed all English papers on APS involvement in the musculoskeletal system using Google Scholar and Pubmed; all reports are summarized in a table in this review. The spectrum of manifestations includes arthralgia/arthritis, avascular necrosis of bone, bone marrow necrosis, complex regional pain syndrome type-1, muscle infarction, non-traumatic fractures, and osteoporosis. Some of these manifestations were reported in good quality studies, some of which showed an association between aPL-positivity and the occurrence of these manifestations, while others were merely described in case reports.

    Full Text Available Rheumatoid arthritis (RA leads not only to a rapid development of disability, but can influence the life of these patients. One-third of patients with rheumatoid arthritis may have signs of disability during the first 3 years of the onset of the disease, while mortality in patients with RA almost two times higher in comparison with the general population. Analysis of recent prospective studies on the progression of the pathological process and predicting of the long-term outcomes in RA clearly indicate the need for clinical evaluation and a comprehensive laboratory and instrumental diagnosis of the disease in the initial manifestations of the most followed by early adequate pathogenetic therapy. The purpose of this survey was to determine modern clinical aspects of diagnosis, the possibility of standard and specialized instrumental examinations in patients with eRA, followed by predicting long-term results. We studied 52 specialized publications on clinical classification and a modern laboratory and diagnostic tests for eRA. This review presents the data of the importance of differentiation of several stages of RA in relation to the time factor. The data on the sensitivity and specificity of the diagnostic classification and clinical criteria of eRA and an algorithm for the identification of the disease were presented. It was shown prognostic value of the main serological markers of RA, and the predictive value for early detection of antibodies to the circulating peptide as a marker of the severity of bone-destructive changes in patients with certain clinical manifestations. Antibodies to the circulating peptide (ACPA can be detected many years before the onset of RA. Study of anti-citrulline mutated vimentin (anti-MCV in patients with eRA can be applied as a marker of activity of the process and the subsequent possibility of use for predicting long-term results. This review presents the major diagnostic errors using standard instrumental

    Full Text Available Spirocercosis is an important disease in South Africa. The object of this study was to determine if there had been a change in the prevalence, clinical manifestations and treatment of Spirocerca lupi over a 14-year period. A questionnaire was sent to 577 veterinary practices throughout South Africa in 2012. Of responders, 76% indicated that S. lupi occurred in their area, whilst 24% indicated that it did not; 84% considered S. lupi not to be a new phenomenon, whereas 16% considered it to be new. Monthly or seasonal distribution of the disease was not reported, and 76% of responders reported it to occur in no specific breed of dog, whereas 24% reported a breed risk, most considering large breeds to be at greater risk. No specific age or sex was identified as at higher risk. Common owner complaints were vomiting, weight loss, cough, or regurgitation. Reported clinical findings tended to mirror the clinical signs reported by owners. Most common diagnostic methods used were radiology, endoscopy, faecal flotation, and post mortem examination. Forty-four percent did not report seeing asymptomatic cases, 40% reported asymptomatic cases and 16% did not know. Associated complications were reported by 85% of responders, and included oesophageal neoplasia, hypertrophic osteopathy and acute haemothorax. Four different drugs were used as therapy: doramectin, ivermectin, milbemycin and Advocate®, with 9% of the responders using a combination of these four; 85% considered treatment to be effective and 15% ineffective. Treatment was considered more effective if the disease was diagnosed early and there were no complications. Two important conclusions were that more cases are being seen and that efficacy of therapy has increased, with a decrease in the mortality rate.

    Leptospirosis is an illness with a wide spectrum of clinical manifestations and severe illness affects nearly all organ systems. Serious and potentially life-threatening clinical manifestations of acute leptospirosis are caused by both direct tissue invasion by spirochaetes and by the host immune responses. In its severe form, leptospirosis can cause multi-organ dysfunction and death in a matter of days. Therefore it is critical to suspect and recognize the disease early, in order to initiate timely treatment. While the classical presentation of the disease is easily recognized by experienced clinicians practising in endemic regions, rarer manifestations can be easily missed. In this systematic review, we summarize the atypical manifestations reported in literature in patients with confirmed leptospirosis. Awareness of these unusual manifestations would hopefully guide clinicians towards early diagnosis.

    Online laboratory manuals have developed into an important gateway to the laboratory. Clinicians increasingly expect up-to-date laboratory test information to be readily available online. During the past decade, sophisticated Internet search technology has developed, permitting rapid and accurate retrieval of a wide variety of content. We studied the role of search in an online laboratory manual. We surveyed the utilization of search technology in publicly available online manuals and examined how users interact with the search feature of a laboratory handbook. We show how a laboratory can improve its online handbook through insights gained by collecting information about each user's activity. We also discuss future applications for search-related technologies and the potential role of the online laboratory manual as the primary laboratory information portal.

    @@ The pathogenesis of childhood primary nephrotic syndrome (PNS) is unclear. However, an immune mechanism has generally been accepted as a cause. Imbalance of T lymphocyte and a variety of inflammatory cytokines, chemotactic and transcription factors are involved in the pathophysiology and manifestations of PNS,1,2 and nuclear factor kappa B (NF-κB) transcriptionally regulates the expression of these factors.3 Research has been focused on NF-κB and inflammatory regulated mediators of renal diseases, but seldom on different clinical manifestations and histopathological changes. In order to explore a potential mechanism for the pathogenesis of PNS in children and a basis for preventing its advance, we determined NF-κB activity in the kidney of children with PNS in vitro using immunohistochemical staining and the multimedia coloured pathological image analysis system and its relations to clinical manifestations, histopathological changes and 24-hour urinary protein excretion.

  17. Clinical Manifestations of Kaposi Sarcoma Herpesvirus (KSHV Lytic Activation: Multicentric Castleman Disease (KSHV-MCD and the KSHV Inflammatory Cytokine Syndrome (KICS

    2012-03-01

    Full Text Available Soon after the discovery of Kaposi sarcoma associated herpesvirus (KSHV, it was appreciated that this virus was associated with most cases of multicentric Castleman disease (MCD arising in patients infected with human immunodeficiency virus (HIV. It has subsequently been recognized that KSHV-MCD is a distinct entity from other forms of MCD. Like MCD that is unrelated to KSHV, the clinical presentation of KSHV-MCD is dominated by systemic inflammatory symptoms including fevers, cachexia and laboratory abnormalities including cytopenias, hypoalbuminemia, hyponatremia, and elevated C-reactive protein. Pathologically KSHV-MCD is characterized by polyclonal, IgM-lambda restricted plasmacytoid cells in the intrafollicular areas of affected lymph nodes. A portion of these cells are infected with KSHV and a sizable subset of these cells express KSHV lytic genes including a viral homolog of interleukin-6 (vIL-6. Patients with KSHV-MCD generally have elevated KSHV viral loads in their peripheral blood. Production of vIL-6 and induction of human (h IL-6 both contribute to symptoms, perhaps in combination with overproduction of IL-10 and other cytokines. Until recently, the prognosis of patients with KSHV-MCD was poor. Recent therapeutic advances targeting KSHV-infected B cells with the anti-CD20 monoclonal antibody rituximab and utilizing KSHV enzymes to target KSHV-infected cells have substantially improved patient outcomes. Recently another KSHV-associated condition, the KSHV inflammatory cytokine syndrome (KICS has been described. Its clinical manifestations resemble those of KSHV-MCD but lymphadenopathy is not prominent and the pathologic nodal changes of KSHV-MCD are absent. Patients with KICS exhibit elevated KSHV viral loads and elevation of vIL-6, hIL-6 and IL-10 comparable to those seen in KSHV-MCD; the cellular origin of these is a matter of investigation. KICS may contribute to the inflammatory symptoms seen in some patients with severe Kaposi

    Kidney transplantation is the treatment-of-choice for a significant number of patients with end-stage renal disease. Renal transplant recipients (RTRs) benefit from a longer life expectancy, with a better quality of life. Despite, recent accomplishments in the field of kidney transplantation, both short- and long-term, surgical and medical complications still exist. Among these complications, cardiovascular disease, carcinogenesis and infections are the most important. Infectious diseases constitute the most common complications after renal transplantation and the second most common cause of death among RTRs with a functioning graft. Theoretically, all infectious pathogens could cause disease in immunocompromised RTRs, yet among these, one could identify more important ones, such as the Enterobacteriaceae, causing urinary tract infections; pneumonia due to Pneumocystis jirovecii; Candida species which cause invasive fungal infections; herpes viruses; hepatitis viruses and parasites. Early diagnosis and effective treatment are key elements in salvaging both the allograft and the patient. However, clinical manifestations and diagnosis of such infectious diseases are not easily identified due to the altered state of immune response of the RTR. Thus, apart from possessing a deep knowledge of the etiology and the treatment options in each case, transplant physicians should also always remain alert when dealing with RTRs.

    A relatively small region of human chromosome 21 (Hsa21) is considered to play a major role in Down syndrome (DS) phenotypes, and the concept of a Down syndrome critical region (DSCR) has been proposed. The goal of the phenotype-genotype correlation study is to discover which genes are responsible for each DS phenotype. Loss of the genomic copy numbers of Hsa21 can give us important suggestion to understand the functions of the involved genes. Genomic copy number aberrations were analyzed by micro-array-based comparative genomic hybridization (aCGH) in 300 patients with developmental delay. Partial deletions of Hsa21 were identified in three patients with developmental delay, epilepsy, microcephaly, and distinctive manifestations. Two of the patients had mosaic deletions of 21q22-qter including a part of DSCR; one of whom whose mosaic ratio was higher than the other showed more severe brain morphogenic abnormality with colpocephaly, which was similar to the previously reported patients having pure deletions of 21q22-qter, indicating the critical region for cortical dysplasia at this region. The remaining patient had the smallest microdeletion with 480 kb in DSCR including DYRK1A and KCNJ6. Although we could not identify any nucleotide alteration in DYRK1A and KCNJ6 in our cohort study for 150 patients with mental retardation with/without epilepsy, this study underscores the clinical importance of DSCR not only for DS but also for developmental disorders.

    Full Text Available Aim. To determine the frequency of macroprolactinemia, its etiology, and the clinical manifestations in patients with hyperprolactinemia presenting with menstrual irregularities, galactorrhea, and/or infertility who were attended by the gynecology-endocrinology service. Methods. In a cross-sectional study, 326 hyperprolactinemic women were tested for serum prolactin (PRL concentrations before and after chromatographic separation (gel filtration and affinity with protein G and extraction of free PRL with polyethylene glycol (PEG. Results. Sera from 57 patients (17.5% were found to have macroprolactinemia. The presence of macroprolactinemia was attributable to anti-PRL autoantibodies in 54 (94.7% patients. The median serum PRL levels were similar in patients with or without macroprolactinemia (42.0 versus 38.1 ng/mL. In contrast, patients with macroprolactinemia had lower serum-free PRL levels (median 9.2 versus 31.7 ng/mL, . Patients without macroprolactinemia had a higher frequency of galactorrhea and abnormal pituitary imagine findings (. Conclusions. We can conclude that macroprolactinemia should be considered as a benign variant, and it must be ruled out in women presenting with menstrual irregularities, galactorrhea, and/or infertility in order to investigate other causes different than hyperprolactinemia. Serum PRL precipitated with PEG is a convenient and simple procedure to screen for the presence of macroprolactinemia.

    In this paper, we report an investigation on cat-scratch disease (CSD) in Northern Italy. Seventy-four cases of CSD were diagnosed at the San Matteo hospital, Pavia, during the period 2005-2010. Of these 74 patients, 18 (24.3 %) reported atypical clinical manifestations such as ocular papillitis, maculopapular eruptions, vertebral infection, pulmonary infiltrates, and granulomatous hepatitis. Contact with cats was documented for 61 patients (82.4 %), while cat-related trauma was reported for 49 patients (66.2 %). We subsequently investigated the presence of Bartonella infection in cats belonging to the above patients and in other domestic and stray cats from three provinces of Northern Italy. Among the 27 domestic cats tested, nine of the 11 belonging to the CSD patients and two of the remaining 16 were infected by B. henselae (81.8 % vs. 12.5 %). Out of over 1,300 stray cats examined, 23.1 % were seropositive for B. henselae; after culturing and genotyping, 17 % were found to be infected by B. henselae (15.5 %) or B. clarridgeiae (1.5 %).

    Synpolydactyly (SPD) is an autosomal dominant limb malformation caused by mutations in the gene HOXD13. We investigated a Chinese family in which three individuals across three generations were affected with distinctive limb malformations. We extracted genomic DNA from the affected and three unaffected individuals from this family as well as 100 unrelated controls, for mutation detection by DNA sequencing. The family was characterized by camptodactyly and symphalangism of fingers two to five, transverse phalanx and osseous fusion of the third metacarpal with the proximal phalanx, as well as the coexistence of mild and more severe bilateral phenotypes. We identified a duplication mutation, c. 186-212dup, in exon 1 of the HOXD13 gene in the affected individuals from this family; it was not present in the unaffected individuals or the 100 unrelated individuals. And we also did not find polymorphism among the controls. This study has expanded the phenotypic spectrum of known HOXD13 polyalanine repeat mutations and provided more information about the polymorphic nature of the polyalanine repeat. In addition, new clinical manifestations have been added to the spectrum of possible synpolydactyly phenotypes.

    Systemic lupus erythematosus (SLE) is an inflammatory rheumatic disease characterized by production of autoantibodies and organ damage. Elevated levels of cytokines have been reported in SLE patients. In this study we have investigated the effect of proinflammatory cytokines (IL-6, TNF-α, and IL-1β) on clinical manifestations in 145 Indian SLE patients. One hundred and forty-five healthy controls of the same ethnicity served as a control group. Clinical disease activity was scored according to SLEDAI score. Accordingly, 110 patients had active disease and 35 patients had inactive disease. Mean levels of IL-6, TNF-α, and IL-1β were found to be significantly higher in SLE patients than healthy controls (P < 0.001). Mean level of IL-6 for patients with active disease (70.45±68.32 pg/mL) was significantly higher (P = 0.0430) than those of inactive disease patients (43.85±63.36 pg/mL). Mean level of TNF-α was 44.76±68.32 pg/mL for patients with active disease while it was 25.97±22.03 pg/mL for those with inactive disease and this difference was statistically significant (P = 0.0161). Similar results were obtained for IL-1β (P = 0.0002). Correlation between IL-6, TNF-α, and IL-1β serum levels and SLEDAI score was observed (r = 0.20, r = 0.27, and r = 0.38, resp.). This study supports the role of these proinflammatory cytokines as inflammatory mediators in active stage of disease. PMID:25548434

    Full Text Available Epidemiological, clinical and laboratory data were collected during an outbreak of trichinellosis, which occurred in Izmir, Turkey, between January and March 2004. The source of the infection was raw meatballs made with a mixture of uncooked beef and pork. Of 474 persons who were admitted at the Ataturk Training and Research Hospital during this period with a history of raw meatball consumption, the diagnosis of trichinellosis was confirmed for 154 (32.5 %, 87 males and 67 females; mean age 31 years, range 6-67 years. Among persons with a confirmed diagnosis, 79 % had myalgia, 77 % weakness and malaise, 63 % arthralgia, 40 % jaw pain, 68 % fever, 63 % periorbital and/or facial oedema, 49 % oedema at the trunk and limb, 42 % abdominal pain, 40 % nausea and vomiting, 28 % diarrhoea, 23 % subconjunctival haemorrhage, 25 % macular or petechial rash, 4 % subungual haemorrhage, 15 % cardiac complaints and 0.2 % neurological complaints. Nine patients (5.8 % were hospitalised due to severe myalgia (n = 2, high fever (n = 3, neurological manifestations (n = 1, thrombophlebitis (n = 2 and palmar erythema (n = 1. Eosinophilia was present in 88 % of the confirmed cases at the admission. Elevated levels of serum creatine phosphokinase, lactic dehydrogenase and aspartate aminotransferase were detected in 72 %, 70 % and 16 % of the confirmed cases, respectively. The seroconversion occurred in most of the infected people between the 4th and 6th weeks after the infection. All of the confirmed cases were treated with mebendazole. People with severe symptoms were treated also with prednisolone (60 mg/day for three days and those with a moderately severe clinical pattern received a non-steroid anti-inflammatory drug (naproxen sodium, 550 mg/day. All confirmed cases recovered without any clinical sequela.

    Several studies have described a wide spectrum of hyperandrogenism diseases, many of which are difficult to distinguish from each other. In order to better understand diseases of hyperandrogenism, the authors performed a retrospective study of the cutaneous features and metabolic findings in women with hyperandrogenism. A retrospective chart analysis compiled by three dermatologists in both academic and private settings was performed, including patients presenting with > or = 2 manifestations of hyperandrogenism. Relevant dermatologic and associated manifestations and laboratory and imaging study findings were reviewed. Moderate to severe acne was the most common manifestation. Other common manifestations that patients first presented with include hirsutism, acanthosis nigricans, androgenic alopecia, and skin tags. Oligomenorrhea was the most common systemic presenting sign. Statistical analysis of various clinical markers revealed correlations with hyperandrogenemia. Acanthosis nigricans and hirsutism were found to be useful clinical markers for hyperandrogenism, whereas androgenic alopecia was not. This study provides some insights into the presentation and diverse manifestations seen in hyperandrogenism.

    Full Text Available OBJECTIVE: To assess whether a difference exists in coronary heart disease clinical manifestations and the prevalence of risk factors between Japanese immigrants and their descendents in the city of São Paulo. METHODS: Retrospective analysis of coronary artery disease clinical manifestations and the prevalence of risk factors, comparing 128 Japanese immigrants (Japanese group with 304 Japanese descendents (Nisei group. RESULTS: The initial manifestation of the disease was earlier in the Nisei group (mean = 53 years, a difference of 12 years when compared with that in the Japanese group (mean = 65 years (P<0.001. Myocardial infarction was the first manifestation in both groups (P = 0.83. The following parameters were independently associated with early coronary events: smoking (OR = 2.25; 95% CI = 1.35-3.77; P<0.002; Nisei group (OR = 10.22; 95% CI = 5.64-18.5; P<0.001; and female sex (OR = 5.04; 95% CI = 2.66-9.52; P<0.001. CONCLUSION: The clinical presentation of coronary heart disease in the Japanese and their descendents in the city of São Paulo was similar, but coronary heart disease onset occurred approximately 12 years earlier in the Nisei group than in the Japanese group.

    Full Text Available Background: Diagnostic health laboratory services are regarded as an integral part of the national health infrastructure across all countries. Clinical laboratory tests contribute substantially to health system goals of increasing quality of care and improving patient outcomes.Objectives: This study aimed to analyse current laboratory expenditures at the primary healthcare (PHC level in South Africa as processed by the National Health Laboratory Service and to determine the potential cost savings of introducing laboratory demand management.Methods: A retrospective cross-sectional analysis of laboratory expenditures for the 2013/2014 financial year across 11 pilot National Health Insurance health districts was conducted. Laboratory expenditure tariff codes were cross-tabulated to the PHC essential laboratory tests list (ELL to determine inappropriate testing. Data were analysed using a Microsoft Access database and Excel software.Results: Approximately R35 million South African Rand (10% of the estimated R339 million in expenditures was for tests that were not listed within the ELL. Approximately 47% of expenditure was for laboratory tests that were indicated in the algorithmic management of patients on antiretroviral treatment. The other main cost drivers for non-ELL testing included full blood count and urea, as well as electrolyte profiles usually requested to support management of patients on antiretroviral treatment.Conclusions: Considerable annual savings of up to 10% in laboratory expenditure are possible at the PHC level by implementing laboratory demand management. In addition, to achieve these savings, a standardised PHC laboratory request form and some form of electronic gatekeeping system that must be supported by an educational component should be implemented.

    This study aims to evaluate the performance of a few biochemistry analysis and make recommendations to the place of the stakeholders. It is a cross-sectional study conducted between the October 1(st), 2012 and the July 31, 2013 bearing on the results of 5 common examinations of clinical biochemistry, provided by 11 laboratories volunteers opening in the public and private sectors. These laboratories have analysed during the 3 cycles, 2 levels (medium and high) of serum concentration of urea, glucose, creatinine and serum aminotransferases. The performance of laboratories have been determined from the acceptable limits corresponding to the limits of total errors, defined by the French Society of Clinical Biology (SFBC). A system of internal quality control is implemented by all laboratories and 45% of them participated in international programs of external quality assessment (EQA). The rate of acceptable results for the entire study was of 69%. There was a significant difference (p<0.002) between the performance of the group of laboratories engaged in a quality approach and the group with default implementation of the quality approach. Also a significant difference was observed between the laboratories of the central level and those of the peripheral level of our health system (p<0.047). The performance of the results provided by the laboratories remains relatively unsatisfactory. It is important that the Ministry of Health put in place a national program of EQA with mandatory participation.

    Impairments in social relatedness and communication, repetitive behaviors, and stereotypic abnormal movement patterns characterize autism spectrum disorders (ASDs). It is clear that while genetic factors are important to the pathogenesis of ASDs, mercury exposure can induce immune, sensory, neurological, motor, and behavioral dysfunctions similar to traits defining or associated with ASDs. The Institutional Review Board of the Institute for Chronic Illnesses (Office for Human Research Protections, U.S. Department of Health and Human Services, IRB number IRB00005375) approved the present study. A case series of nine patients who presented to the Genetic Centers of America for a genetic/developmental evaluation are discussed. Eight of nine patients (one patient was found to have an ASD due to Rett's syndrome) (a) had regressive ASDs; (b) had elevated levels of androgens; (c) excreted significant amounts of mercury post chelation challenge; (d) had biochemical evidence of decreased function in their glutathione pathways; (e) had no known significant mercury exposure except from Thimerosal-containing vaccines/Rho(D)-immune globulin preparations; and (f) had alternate causes for their regressive ASDs ruled out. There was a significant dose-response relationship between the severity of the regressive ASDs observed and the total mercury dose children received from Thimerosal-containing vaccines/Rho (D)-immune globulin preparations. Based upon differential diagnoses, 8 of 9 patients examined were exposed to significant mercury from Thimerosal-containing biologic/vaccine preparations during their fetal/infant developmental periods, and subsequently, between 12 and 24 mo of age, these previously normally developing children suffered mercury toxic encephalopathies that manifested with clinical symptoms consistent with regressive ASDs. Evidence for mercury intoxication should be considered in the differential diagnosis as contributing to some regressive ASDs.

    2015-01-01

    Full Text Available Objective: to estimate the contribution of HLA-B5/51 genotype to the clinical manifestations and risk of Behcet’s disease (BD in two ethnic groups.Subjects and methods. 146 BD patients fulfilling the International Criteria for BD (ICBD were divided into two ethnic groups: 1 86 patients from Dagestan (representatives of 8 ethnic nationalities in this region with mean age 30.7±9.6 years; disease duration – 8.8±10.1 years; 2 60 ethnic Russian patients, nonresidents of Dagestan with mean age 32.9±11.1 years; disease duration – 11.2±10.1 years. All patients were examined at the V.A. Nasonova Research Institute of Rheumatology in 1990 to 2014. HLA class I antigens were typed by a microlymphocytotoxic technique using a Gisans anti-leukocyte sera kit (Saint Petersburg.Results. HLA-B5/51 was detected in 87 (59.6% patients, much more often in men than in women (70 and 38%, respectively; p<0.01. Genital ulcers and erythema nodosum were significantly more common in HLA-B5/51-positive Dagestani (87.3 and 57% than in HLA-B5/51-negative ones (56.5 and 26%; p=0.0019 and р=0.01; respectively. There were no significant differences in these signs in the Russian group of patients with BD depending on the presence of this allele. In HLA-B5/51-positive male Dagestani patients with BD, the risk of erythema nodosum was twice as high as that in HLA-B5/51-negative patients (p=0.054. In HLA-B5/51 female Dagestani carriers, the risk of genital ulcers and generalized uveitis proved to be 3.5 (p=0.057 and 2.7 times higher than that in HLA-B5/51 noncarriers. Frequency of HLA-B5/51 was 73.2% among the Dagestanis and 40% among the Russians. Furthermore, this investigation revealed HLA-B5/51 carriage mainly in the male BD patients. Therefore, in addition to ethnicity, gender should be borne in mind when analyzing the clinical associations with HLA-B5/51.

    Full Text Available HLA-linked genes are relevant to celiac disease (CD; the potential genetic differences present worldwide are not fully understood. Previous results suggest that the distribution of HLA-DQ2/DQ7/DQ8 in Chile may differ from that in Europe and North America. In celiac patients and their first-degree relatives (FDRS, we assessed their clinical, serological and histological characteristics, determined HLA-DQ2, HLA-DQ7 and HLA-DQ8 alleles and genotypes, and evaluated the relations between them. A total of 222 individuals were assessed (56 cases, 166 FDRs. 16.9% of FDRs were tTG positive; 53.6% of them showed overweight/obesity and 3% undernourishment; they spontaneously declared being asymptomatic, but detailed questioning revealed that 60.7% experienced symptoms, which had not been investigated. DQ2 was present in 53.9% and 43.9.0% of cases and FDRs (p < 0.05. The most frequent genotype distribution was DQ2/DQ7 (fr 0.392 (cases and 0.248 (FDRs, respectively, p < 0.02. The next most common genotypes were HLA-DQ2/DQ8 (fr 0.236 in FDRs and 0.176 in cases, p < 0.05. 3.92% cases were not HLA-DQ2/DQ8 carriers. Among tTG positive FDRs, 57.4%, 22.3% and 20.2% carried DQ2, DQ7 and DQ8, respectively. In cases, 72.7% of the biopsies classified Marsh ≥3 carried at least one DQ2; 91.7% of DQ2/DQ2 and 88.3% of DQ2/DQ7 were Marsh ≥3. Thus, DQ2 frequency is lower than reported; the higher frequency found for DQ8 and DQ7 concur with recent publications from Argentine and Brazil. These results suggest that although CD may manifest clinically in ways similar to those described in other populations, some genetic peculiarities in this region deserve further study.

    2015-10-01

    Test anxiety is a highly prevalent and impairing syndrome. However, research on clinically relevant manifestations of test anxiety and especially on effective treatment components is still very sparse. In the present study we examined the predictive validity of constructs derived from the self-regulative model for evaluation anxiety proposed by Zeidner and Matthews (2007) for discriminating clinical and non-clinical levels of test anxiety. We compared self-report data from 47 clinically test anxious patients with those from 41 healthy university students. Results showed that learning goals, self-concept of abilities, self-incrimination, elaboration and perfectionism were the constructs that independently separated clinical from non-clinical levels of test anxiety, thus providing the strongest discriminant validity even when controlling for an effect of the global severity of mental health problems. These constructs spread across all three domains proposed in the model, thus providing important implications for possible targets of interventions to reduce clinical levels of test anxiety.

    Better biomarkers are urgently needed to cancer detection, diagnosis, and prognosis. While the genomics community is making significant advances in understanding the molecular basis of disease, proteomics will delineate the functional units of a cell, proteins and their intricate interaction network and signaling pathways for the underlying disease. Great progress has been made to characterize thousands of proteins qualitatively and quantitatively in complex biological systems by utilizing multi-dimensional sample fractionation strategies, mass spectrometry and protein microarrays. Comparative/quantitative analysis of high-quality clinical biospecimen (e.g., tissue and biofluids) of human cancer proteome landscape has the potential to reveal protein/peptide biomarkers responsible for this disease by means of their altered levels of expression, post-translational modifications as well as different forms of protein variants. Despite technological advances in proteomics, major hurdles still exist in every step of the biomarker development pipeline. The National Cancer Institute's Clinical Proteomic Technologies for Cancer initiative (NCI-CPTC) has taken a critical step to close the gap between biomarker discovery and qualification by introducing a pre-clinical "verification" stage in the pipeline, partnering with clinical laboratory organizations to develop and implement common standards, and developing regulatory science documents with the US Food and Drug Administration to educate the proteomics community on analytical evaluation requirements for multiplex assays in order to ensure the safety and effectiveness of these tests for their intended use.

  18. Liposomal drug delivery system from laboratory to clinic

    2005-01-01

    Full Text Available The main objective of drug delivery systems is to deliver a drug effectively, specifically to the site of action and to achieve greater efficacy and minimise the toxic effects compared to conventional drugs. Amongst various carrier systems, liposomes have generated a great interest because of their versatility. Liposomes are vesicular concentric bilayered structures, which are biocompatible, biodegradable and nonimmumnogenic. They can control the delivery of drugs by targeting the drug to the site of action or by site avoidance drug delivery or by prolonged circulation of drugs. Amphotericin B (Amp B remains the drug of choice in most systemic mycoses and also as a second line treatment for Kala azar. However, its toxic effects often limit its use. Although the liposome delivery system has been tried for several drugs, only a few have been used in patients due to the slow development of necessary large-scale pharmaceutical procedures. This paper reviews the development of the technique for liposomal Amphotericin B (L-Amp-LRC-1, FungisomeTM drug delivery system in our laboratory in collaboration with the department of Biochemistry, Delhi University in India and proving the safety and efficacy of this preparation in clinical practice. It also attempts to compare the efficacy and benefits of our product for Indian patients with those of similar products and it includes facts from the publications that flowed from our work. As compared to conventional Amp B, Fungisome is infused over a much shorter period requiring a smaller volume and no premedication. It was found to be safe in patients who had developed serious unacceptable toxicity with conventional Amp B. In renal transplant patients, Fungisome did not produce any nephrotoxicity. Fungisome is effective in fungal infections resistant to fluconazole, conventional Amp B and in virgin and resistant cases of visceral leishmaniasis. The cost of any drug is of great significance, especially in India

    This commentary will introduce lean concepts into the clinical microbiology laboratory. The practice of lean in the clinical microbiology laboratory can remove waste, increase efficiency, and reduce costs. Lean, Six Sigma, and other such management initiatives are useful tools and can provide dividends but must be accompanied by organizational leadership commitment to sustaining the lean culture in the laboratory setting and providing resources and time to work through the process.

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

    The subacute spongiform encephalopathies are prion diseases characterized by acute and rapid neurodegeneration that lead to the death of the patient within months to a few years. The epidemiology of CJD is complicated and the frequency in Mexico is unknown. We aim to describe the cases of prion disease in Mexico. Consecutive patients who met the diagnostic criteria by the WHO were enrolled. We describe 26 patients with clinical manifestations, imaging and laboratory studies compatible with prion disease. The mean age at onset was 52 years old. The main clinical manifestations were cognitive alterations (69%) followed by extrapyramidal movements (50%), abnormal cerebellar function (46%), behavioral alterations (46%), myoclonus (46%), and mood depression (23%), among other features. Half of the patients progressed rapidly to a state of akinetic mutism (53%). Only 2 (7.6%) patients had a family history of a similar disease. Time interval between onset and diagnosis varied between 71 days to 24 months, with a median of 6 months. The classical bilateral basal ganglia hyperintensities were present in the very early stage of the disease. Protein 14-3-3 immuneassay in the CSF was positive in all measured cases. Bilateral basal ganglia hyperintensities was the most important early finding, while protein 14-3-3 was a late finding and the results were usually obtained after the patient was discharged. Around 1.5 cases of CJD cases per year are reported in our country. When suspected, MRI can support the diagnosis earlier than other studies.

    Full Text Available In Brazil, current trends of the AIDS epidemic include an increase in transmission through heterosexual contact, predominantly from men to women, with more cases of AIDS in women and more children contaminated by vertical transmission. There is also a high proportion of cases in poor people or people living in small towns. HIV-infected patients with high levels of immunodeficiency are frequently hospitalized after their first visit to the clinic due to opportunistic infections, characteristic of advanced disease. This study characterized the clinical and laboratory pattern of AIDS in a sample of patients attended for the first time in the AIDS clinic of the Federal University of Bahia Hospital (HUPES in Salvador, Brazil. We revised medical charts of cases of subjects registered at the outpatient AIDS clinic from January 1997 to December 2003. The demographics, clinical data, and laboratory characteristics were analyzed to determine the degree of immunodeficiency at the time of admission. A total of 377 patients were evaluated (58.6% were male, with a mean sample age of 33.4 years. The most frequent clinical manifestations were asthenia, weight loss, fever, anemia, dermatitis, oral thrush and diarrhea. CDC criteria were not adequate to define the initial cases. After admission to the outpatient clinic, nearly 25% of the patients were hospitalized immediately, indicating delay in the diagnosis. In Bahia, the initial presentation of HIV-infected patients to health care assistance is occurring at a late stage of the disease, when signs and symptoms of immunodeficiency are already established. Efforts are necessary to construct strategies to make an early diagnosis of these patients, improve the quality of care, and guarantee the benefits of antiretroviral therapy, when it is indicated.

    Hepatitis A virus (HAV) infection has several atypical manifestations, including fulminant hepatitis, relapsing hepatitis, prolonged cholestasis and extrahepatic manifestations. In this study, we aimed to describe the characteristics and outcomes of the pediatric patients with atypical manifestations of HAV infection. Four hundred twelve children with symptomatic hepatitis A infection admitted to Gaziantep Children's Hospital Department of Pediatric Infectious Disease between August 2011 and January 2013 were analyzed retrospectively. Atypical presentations were present in 53 (12.8%) children of 412 children with HAV infection. Patients with atypical presentations (8.3±3.7 years) were older than patients with typical presentations (5.9±3.1 years) (p=0.001). Children with atypical features of hepatitis A statistically had higher initial and peak values of alanine aminotransferase (ALT), aspartate aminotransferase (AST), international normalized ratio (INR), serum total and direct bilirubin than typical manifested group. We can conclude that older age is the major risk factor for atypical presentation of HAV infections. Higher initial and peak levels of AST, ALT, INR, total and direct bilirubin could predict the atypical manifestation.

    Full Text Available La oftalmopatía es una manifestación común de la enfermedad tiroidea autoinmune. El edema periorbitario, la retracción palpebral, el exoftalmos y las alteraciones visuales son signos y síntomas frecuentes. De un 25 a un 50% de los pacientes con hipertiroidismo de Graves tendrán algunas manifestaciones de oftalmopatía. Todos los síntomas clínicos visuales significativos y los hallazgos de los pacientes con oftalmopatía de Graves pueden ser englobados dentro de dos fenómenos: el engrosamiento del espacio retrobulbar debido al depósito de glicosaminoglicanos (GAG o a la restricción de la motilidad extraocular, que se atribuye a un engrosamiento inicial y posterior fibrosis. Los pacientes con enfermedad de Graves típicamente se quejan de dolor ocular o periocular, lagrimeo, fotofobia, visión borrosa, diplopia, o percepción cromática alterada. A la exploración, muestran congestión orbitaria, proptosis, neuropatía óptica, restricción de la motilidad ocular extrínseca, ejes visuales divergentes, exposición corneal, retracción palpebral y edema periorbitario. En este trabajo se describen las principales manifestaciones clínicas de la oftalmopatía de Graves con el objetivo de establecer unas clasificaciones medibles y reproducibles que puedan ser empleadas en la clínica diaria para objetivar cambios y guiar y adecuar la terapia. Finalmente, recomendamos el uso de medidas objetivas para la proptosis, movimientos extraoculares, alteraciones corneales y del nervio óptico, usando una escala de actividad clínica o cambios en medidas objetivas para poder establecer la actividad de la enfermedad, y finalmente, reflejar la percepción de los pacientes de su estado de enfermedad.Ophthalmopathy is a common manifestation of autoimmune thyroid disease.

    Full Text Available Adult-onset Still’s disease is an inflammatory multisystemic disease of unknown etiology. Pleuritis is the most common pulmonary manifestation and pleural effusions are usually exudates with a predominance of neutrophils. We report a case of an eosinophilic pleural effusion as a novel and hitherto unrecognized manifestation of active adult-onset Still’s disease. We also observed a marked NLRP3 inflammasome activation with increased production of IL-1β which coincided with the development and resolved upon remission of the pleural effusion suggesting a possible novel pathogenetic pathway for the development of pleural effusions in the context of the auto-inflammatory disorders.

    We performed customer satisfaction surveys for physicians and nurses regarding clinical laboratory services, and for outpatients who used phlebotomy services at a tertiary care unit level to evaluate our clinical laboratory and phlebotomy services. Thus, we wish to share our experiences with the customer satisfaction survey for clinical laboratory and phlebotomy services. Board members of our laboratory designed a study procedure and study population, and developed two types of questionnaire. A satisfaction survey for clinical laboratory services was conducted with 370 physicians and 125 nurses by using an online or paper questionnaire. The satisfaction survey for phlebotomy services was performed with 347 outpatients who received phlebotomy services by using computer-aided interviews. Mean satisfaction scores of physicians and nurses was 58.1, while outpatients' satisfaction score was 70.5. We identified several dissatisfactions with our clinical laboratory and phlebotomy services. First, physicians and nurses were most dissatisfied with the specimen collection and delivery process. Second, physicians and nurses were dissatisfied with phlebotomy services. Third, molecular genetic and cytogenetic tests were found more expensive than other tests. This study is significant in that it describes the first reference survey that offers a survey procedure and questionnaire to assess customer satisfaction with clinical laboratory and phlebotomy services at a tertiary care unit level.

    Full Text Available A retrospective study of 42 cases of acute flaccid paralysis (AFP in children aged between 7 months and 15 years, registered at the Municipal Clinical Hospital №1 throughout a 7 year period (2007—2014, was performed to investigate the features of pediatric Guillian-Barre Syndrome (GBS. GBS has shown to be the most common cause of AFP in children, with prevalence of 74% of all 31 cases. Clinical manifestations, functional status, laboratory and electrodiagnostic data were evaluated in group of 31 children in order to highlight particular features of childhood GBS in Russia. The highest frequency of GBS was observed in children aged between 1 to 3 with the median 6 [3; 11] years. Boys with GBS outnumbered girls by a 2,1:1 ratio. No seasonal dependence has been observed, with children equally suffering from this disease without a seasonal pattern throughout the year. According to the electrophysiological and clinical data, 24 children were diagnosed with acute inflammatory demyelinating polyradiculoneuropathy (AIDP (77%, 5 with acute motor axonal neuropathy (AMAN (16% and 2 with аcute motor-sensory axonal neuropathy (AMSAN in a total of cases (7%. Several exclusive features of GBS in children for Russia were discovered. The most common initial symptom was limb pain, with the impartial sensory disturbance found only in 13% of the patients observed, 10% of which were paresthesias and the remaining 3% belonging to hypostesias. Children reached the nadir state rapidly, the median time from onset to nadir was 9.5 [6,25; 12,5] days. Cranial nerve dysfunction at nadir was observed in a greater percentage of patients (51% compared to that of 23% cases at the onset, with the facial palsy increasing from 10 to 32% and the bulbar palsy from 12 to 19%.

    2013-09-01

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

  1. Pre-analytical phase in clinical chemistry laboratory

    2016-07-01

    Full Text Available The laboratory testing process is divided into the pre-analytical, analytical and post-analytical phases. For obtaining reliable test results, the prevention and detection of errors at all steps is required. While analytical standards have been developed by recognized quality control criteria, there is a scarcity in the development of standards for the preanalytical phase. This phase is most prone to errors as the steps involved are directly dependent on humans and are out of direct control of the laboratory. Such errors in preanalytical stage often only become apparent in the analytical or post-analytical phase. The development of a pre-analytical quality manual is essential in achieving total quality control. Correct practices and strategies of error prevention can reduce preanalytical errors. This review focuses on prevention of pre-analytical errors that occur while collecting a specimen of blood, urine and cerebrospinal fluid. Most of these can be easily prevented with understanding and education of the personnel involved in and responsible for executing this crucial pre-analytical phase.

    2005-10-01

    Hepatitis C affects approximately 170 million people worldwide. Extrahepatic manifestations of chronic hepatitis C infection are clinically evident in nearly 40% of patients. Much research has been done over the last decade to better understand their incidence, clinical presentation, mechanism of disease, and the role of antiviral therapy in their treatment. Of the commonly reported manifestations, cryoglobulinemia, membranoproliferative glomerulonephritis, and porphyria cutanea tarda remain the best understood manifestations. More recently, the association of insulin resistance and diabetes mellitus with chronic hepatitis C has been demonstrated. This paper serves to review the growing body of literature detailing the extrahepatic manifestations of chronic hepatitis C.

  3. Experimental Psychopathology: From laboratory studies to clinical practice

    2006-03-01

    Full Text Available Recently, David Barlow (2004, a pioneer in the field of anxiety disorders, has proposed that psychologists should abandon the concept of psychotherapy and rather use the one of “psychological treatment”. The provoking idea behind this proposal is that the concept of psychotherapy, relying on the notion of “therapeutic school” should be discarded by professional psychologists because it relies too much on conceptions based on pre-scientific models. Barlow (2004 insists that, today, psychology as an empirical science has gathered sufficient knowledge and know-how to found clinical practice. It is no longer necessary to rely on pre-scientific theories. Further, Barlow’s perspective opens clinical practice to the entire field of psychology, i.e. to the advances accomplished by research on emotion, cognition, learning, development, etc.

    2010-01-01

    Full Text Available DOCK8 immunodeficiency syndrome (DIDS is a combined immunodeficiency characterized by recurrent viral infections, severe atopy, and early onset malignancy. Genetic studies revealed large, unique deletions in patients from different families and ethnic backgrounds. Clinical markers of DIDS include atopic dermatitis, allergies, cutaneous viral infections, recurrent respiratory tract infections, and malignancy. Immune assessments showed T cell lymphopenia, hyper-IgE, hypo-IgM, and eosinophilia. The impaired lymphocyte functions in DIDS patients appear central for disease pathogenesis.

    Studies on serotype-specific features of dengue and disease severity on adults are limited. We prospectively recruited adult febrile patients without alternate diagnosis to dengue from April 2005 to December 2011. Outcomes were defined using both the World Health Organization (WHO) 1997 and 2009 criteria; Dengue hemorrhagic fever (DHF) and severe dengue (SD). Infecting serotype was identified in 469 dengue-confirmed patients comprising 22.0% dengue virus serotype 1 (DENV-1), 57.1% DENV-2, 17.1% DENV-3, and 3.8% DENV-4. Cases infected with DENV-1 were more likely to present with red eyes whereas presence of joint pain and lower platelet count was associated with DENV-2 cases. After adjusting for potential confounders, DENV-1 was associated with both DHF (adjusted Relative Risk [aRR] = 1.74) and SD (aRR = 2.1) whereas DENV-2 had a lower risk of DHF (aRR = 0.5). DENV-1 genotype 1 and DENV-2 cosmopolitan were the predominant genotypes identified. Infecting dengue serotype and possibly genotype may play an important role in disease severity among adult dengue patients in Singapore.

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

    Full Text Available Background and Objective: laboratory personnel have always accidental exposure to clinical samples, which can cause the transmission of infection. This threat can be prevented and controlled by education for the use of safety instruments. The purpose was to determine the frequency of accidental exposure to laboratory samples among Yazd laboratory personnel in 2011. Material and Methods: This descriptive cross-sectional study was conducted on 100 of Yazd clinical laboratory personnel. The data was collected, using a valid and reliable questioner, via interview and analyzed by means of SPSS software. Results: Eighty-six percent of the subjects reported an experience of accidental exposure to clinical samples, such as blood, serum and urine. The causes were carelessness (41% and work overload (29%. Needle- stick was the most prevalent injury (52% particularly in sampler workers (51% and in their hands (69%. There wasn’t significant relationship between accidental exposure to laboratory samples and the variables such as private and governmental laboratories (p=0.517, kind of employment (p=0.411, record of services (p=0.439 and academic degree (p=0.454. The subjects aged 20-29 (p=0.034 and worked in sampling unit had the highest accidental exposure. Conclusion: based on the results, inexperience of the personnel especially in sampling room, overload at work and ignorance of applying safety instruments are known as the most important reasons for accidental exposure to clinical samples.

    Full Text Available Leptospirosis has a spectrum of presentation which ranges from mild disease to a severe form comprising of jaundice and renal failure. Involvement of the lung can vary from subtle clinical features to deadly pulmonary hemorrhage and acute respiratory distress syndrome. Of late, it has been identified that leptospirosis can present atypically with predominant pulmonary manifestations. This can delay diagnosis making and hence optimum treatment. The purpose of this review is to bring together all the reported pulmonary manifestations of leptospirosis and the recent trends in the management.

    Full Text Available I laboratori clinici operano in stretto contatto con i pazienti e collaborano direttamente alla loro cura, in modo corresponsabile con i medici e i reparti ospedalieri. L’importanza della loro attività per la salute pubblica rende obbligatoria l’esplicitazione di alcuni punti finora spesso considerati ovvii. Ai pazienti dev’essere infatti garantito che: - i metodi di analisi utilizzati siano stati preliminarmente valutati, per confermare la loro rispondenza agli obiettivi dell’analisi stessa, verificati, per controllarne l’effettiva efficacia e, se necessario, validati per garantire che siano appropriati allo scopo; - il personale che esegue le analisi sia stato adeguatamente formato e quindi tecnicamente competente; - il laboratorio assicuri un’adeguata consulenza allo staff clinico che richiede le analisi, allo scopo di ottenere una sinergia tra il laboratorio e il clinico che ha in cura il paziente, sia nella fase di prelievo di materiale biologico, sia nella fase di interpretazione dei risultati.

    Full Text Available CONTEXT: Renal allograft biopsies have been used as a good method for monitoring the evolution of kidney transplants for at least 20 years.1 Histological analysis permits differential diagnosis of the causes of allograft dysfunction to be made. OBJECTIVES: To correlate the data of urinalysis and serum creatinine with histological diagnosis of renal graft in a group of renal transplant patients. DESIGN: Accuracy study, retrospective analysis. SETTING: A university terciary referral center. SAMPLE: 339 percutaneous allograft biopsies obtained from 153 patients. Blood and urine samples were obtained before the graft biopsy. MAIN MEASUREMENTS: Laboratory evaluation and hystological analysis (light microscopy, imunofluorescent eletronic microscopy. RESULTS: Most of the biopsies (58.9% were performed during the first month post-transplant. An increase in serum creatinine was associated with acute tubular and/or cortical necrosis. Proteinuria and normal serum creatinine were associated with glomerular lesions. Non-nephrotic range proteinuria and an increase in serum creatinine were associated with chronic rejection. CONCLUSIONS: Evaluation of serum creatinine and urinalysis can be useful in suggesting the histological graft diagnosis.

  19. Trigeminal Neuralgia as the First Clinical Manifestation of Anti-Hu Paraneoplastic Syndrome Induced by a Borderline Ovarian Mucinous Tumor

    Directory of Open Access Journals (Sweden)

    Hossein Kalanie

    2014-01-01

    Full Text Available Paraneoplastic neurologic syndrome (PNS is an uncommon manifestation of cancer that is not caused by the tumor or metastasis. Trigeminal neuralgia (TN is an initial symptom of this disease, but it has rarely been reported in the literature. Here, we report the case of a 76-year-old woman who presented with classic TN, followed by limbic encephalitis due to an underlying ovarian intestinal-type mucinous borderline tumor, with the presence of anti-Hu antibodies. She recovered quickly after removal of the tumor and was essentially free of symptoms 2 weeks after surgery. Because PNS precedes the tumor in approximately 60% of cases, its rapid detection and treatment are crucial. Therefore, we propose that PNS be considered during the management of TN when brain imaging is normal, as it is followed by other central and/or peripheral neurological manifestations as well as the presence of systemic symptoms such as anemia, fatigability, loss of appetite, or weight loss.

    Patients involved on coeliac disease (CD) have atypical symptoms and often remain undiagnosed. Specific oral manifestations are effective risk indicators of CD and for this reason an early diagnosis with a consequent better prognosis can be performed by the dentist. There are not researches analysing the frequency of these oral manifestations in potential coeliac patients. The aim of this study is to investigate the oral hard and soft tissue lesions in potential and ascertained coeliac children in comparison with healthy controls. 50 ascertained children, 21 potential coeliac patients, and 54 controls were recruited and the oral examination was performed. The overall oral lesions were more frequently present in CD patients than in controls. The prevalence of oral soft tissue lesions was 62% in ascertained coeliac, 76.2% in potential coeliac patients, and 12.96% in controls (P coeliac and 42.5% of the potential coeliac versus 11.11% of the controls (P coeliac and 19% in potential coeliac versus 0% in controls (P villous atrophy.

    Hepatitis C does not only affect the liver, but also manifests outside the liver. The skin, kidneys and nervous system are often involved due to mixed cryoglobulinaemia. Porphyria cutanea tarda, lymphoma and thyroid diseases among others can also attend a chronic infection, but the exact pathogenesis behind these manifestations is not clearly mapped. Antiviral treatment is reported to induce sustained virological response in more than half of the treated patients with a variable clinical response in the extrahepatic manifestations.

    In the early 80s, the word automation was used in the clinical laboratory setting referring only to analyzers. But in late 80s and afterwards, automation found its way into all aspects of the diagnostic process, embracing not only the analytical but also the pre- and post-analytical phase. While laboratories in the eastern world, mainly Japan, paved the way for laboratory automation, US and European laboratories soon realized the benefits and were quick to follow. Clearly, automation and robotics will be a key survival tool in a very competitive and cost-concious healthcare market. What sets automation technology apart from so many other efficiency solutions are the dramatic savings that it brings to the clinical laboratory. Further standardization will assure the success of this revolutionary new technology. One of the main difficulties laboratory managers and personnel must deal with when studying solutions to reengineer a laboratory is familiarizing themselves with the multidisciplinary and technical terminology of this new and exciting field. The present review/glossary aims at giving an overview of the most frequently used terms within the scope of laboratory automation and to put laboratory automation on a sounder linguistic basis.

    In 2010-2013, the quality of microscopic detection of the causative agents ofparasitic diseases in the feces has been assessed by the specialists of the laboratories of the therapeutic-and-prophylactic institutions (TPIs) and Hygiene and Epidemiology Centers, Russian Inspectorate for the Protection of Consumer Rights and Human Welfare, which are participants of the Federal System of External Quality Assessment of Clinical Laboratory Testing. Thirty-two specimens containing 16 species of human helminths and 4 species of enteric protozoa in different combinations were examined. The findings suggest that the quality of microscopic detection of the causative agents of parasitic diseases is low in the laboratories of health care facilities and that the specialists of the laboratories of TPIs and Hygiene and Epidemiology Centers, Russian Inspectorate for the Protection of Consumer Rights and Human Welfare, do not not possess the knowledge and skills necessary to make a laboratory diagnosis of helminths and enteric protozoa. The average detection rates of helminths and protozoa were at a level of 64 and 36%, respectively. The correct results showed that the proportion of helminths and protozoa were 94.5 and 5.5%, respectively. According to the biological and epidemiological classification of helminths, there were higher detection rates for contact group parasites (Enterobius vermicularis and Hymenolepis nana) and geohelminths (Ascaris, Trichuris trichiura, and others). Biohelminths (Opisthorchis, tapeworms, and others) Were detectable slightly worse.

    Despite recent advances in diagnostic technology, microscopic examination of stool specimens remains central to the diagnosis of most pathogenic intestinal protozoa. Microscopy is, however, labor-intensive and requires a skilled technologist. New, highly sensitive diagnostic methods have been developed for protozoa endemic to developed countries, including Giardia lamblia (syn. G. intestinalis/G. duodenalis) and Cryptosporidium spp., using technologies that, if expanded, could effectively complement or even replace microscopic approaches. To date, the scope of such novel technologies is limited and may not include common protozoa such as Dientamoeba fragilis, Entamoeba histolytica, or Cyclospora cayetanensis. This minireview describes canonical approaches for the detection of pathogenic intestinal protozoa, while highlighting recent developments and FDA-approved tools for clinical diagnosis of common intestinal protozoa.

    In the reported study the role of single-photon emission tomography (SPET) with technetium-99m hexamethylpropylene amine oxime (HMPAO) in the evaluation of CNS involvement in SLE was assessed and the relations between SPET perfusion defects, EEG examination, magnetic resonance imaging (MRI) findings and clinical presentation were examined. Twenty SLE patients with different NP manifestations were studied. Multiple areas of hypoperfusion, especially in the territory of the middle cerebral artery, were demonstrated by SPET analysis in all 20 patients. The number of hypoperfused areas and the degree of hypoperfusion, expressed by an asymmetry index (AI), were more marked in patients with multiple NP manifestations. MRI and EEG evaluations were positive for 14 of 18 and for 12 of 20 patients, respectively. In the patients with positive SPET and MRI, 87 MRI focal lesions and 63 hypoperfused areas were found, and for 51 of these 63 at least one MRI lesion was found in the same anatomical region. SPET examination of patients with a normal EEG showed fewer hypoperfused areas and a lower degree of asymmetry compared to patients with an abnormal EEG. SPET of patients with focal EEG abnormalities showed more hypoperfused areas (difference not statistically significant) and a higher AI than did SPET of the patients with diffuse EEG abnormalities. Seven of 11 anatomical regions with focal EEG abnormalities. Seven of 11 anatomical regions with focal EEG abnormalities had co-localized hypoperfused areas and in two of these seven no detectable MRI lesions were found. The analysis of SPET and NP manifestations showed that 12 of 20 patients had at least one positive correlation, always involving the areas with the highest AI. In total, 51/88 (58%) hypoperfused areas correlated with the MRI findings and 31/88 (35%) with NP manifestations; for seven of the latter no concurrent MRI lesions were detected in the same anatomical region.

    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.

    Full Text Available In the last 20 years in medical laboratories, numerous activities regarding quality and accreditation system were taken. Approach to this problem in European countries is different, so the task of the Accreditation Work Group of the Confederation of European societies for clinical chemistry (EC 4 to help the efforts to harmonize this issue. External quality control in clinical-chemical laboratories imposed the need for the implementation of quality management system. »Good laboratory practice« and its principles were adopted by nominated bodies, both international and national. In the beginning, the standard ISO 9001 was applied for certification and for accreditation EN 45001 and ISO Guide 25, which are prepared for testing and calibration laboratories. Standard ISO 17025 is the successor of the previous documents and for now it is a reference for mentioned laboratories. Accreditation Work Group of the Confederation of European societies for clinical chemistry (EC 4 made an amendment of the requirements
