    Sweet Syndrome is an acute inflammatory skin eruption which is rare in children. We report a case of childhood Systemic Lupus Erythematosus (SLE) that presented with Sweet syndrome. This case is a unique presentation of a common disorder which provides a new facet for the differential diagnosis of SLE in children. It is also the first paediatric case to be reported in a Caucasian child.

    Sweet syndrome (acute, febrile, neutrophilic dermatosis) is characterized by the acute onset of an eruption of painful nodules or erythematous or violaceous plaques on the limbs, face and neck. These symptoms are accompanied by fever. The diagnostic features include histopathological findings of dermal neutrophilic infiltration without leukocytoclastic vasculitis or peripheral blood leukocytosis. Sweet syndrome is associated with infection, malignancies, autoimmune disease, pregnancy, and drugs. Patients with Sweet syndrome demonstrate a complete and rapid response to systemic steroid administration. Recently, a distinct variant of Sweet syndrome was reported, termed "histiocytoid Sweet syndrome", in which the infiltration of myeloperoxidase-positive histiocytoid mononuclear cells are observed (in contrast to the infiltration of neutrophils). The other clinical features are similar to those of classic Sweet syndrome. Pediatric Sweet syndrome is uncommon, and the histiocytoid type is even rarer. To date, four cases of histiocytoid Sweet syndrome have been reported in children. Herein, we describe a case of histiocytoid Sweet syndrome in an otherwise healthy 10-year-old boy with no underlying systemic disease in whom non-steroidal, anti-inflammatory drug treatment was successful.

    Histiocytoid Sweet syndrome is a rare histopathologic variant of Sweet syndrome. The nature of the histiocytoid infiltrate has generated considerable controversy in the literature. The main goal of this study was to conduct a comprehensive overview of the immunohistochemical phenotype of the infiltrate in histiocytoid Sweet syndrome. We also analyze whether this variant of Sweet syndrome is more frequently associated with hematologic malignancies than classic Sweet syndrome. This is a retrospective case series study of the clinicopathologic, immunohistochemical, and molecular features of 33 patients with a clinicopathologic diagnosis of histiocytoid Sweet syndrome was conducted in the dermatology departments of 5 university hospitals and a private laboratory of dermatopathology. The clinical, histopathological, immunohistochemical, and follow-up features of 33 patients with histiocytoid Sweet syndrome were analyzed. In some cases, cytogenetic studies of the dermal infiltrate were also performed. We compare our findings with those of the literature. The dermal infiltrate from the 33 study patients (20 female; median age, 49 years; age range, 5-93 years; and 13 male; median age, 42 years; age range, 4-76 years) was mainly composed of myeloperoxidase-positive immature myelomonocytic cells with histiocytoid morphology. No cytogenetic anomalies were found in the infiltrate except in 1 case in which neoplastic cells of chronic myelogenous leukemia were intermingled with the cells of histiocytoid Sweet syndrome. Authentic histiocytes were also found in most cases, with a mature immunoprofile, but they appeared to be a minor component of the infiltrate. Histiocytoid Sweet syndrome was not more frequently related with hematologic malignancies than classic neutrophilic Sweet syndrome. The dermal infiltrate of cutaneous lesions of histiocytoid Sweet syndrome is composed mostly of immature cells of myeloid lineage. This infiltrate should not be interpreted as leukemia cutis.

    A case of hypertrophic cranial pachymeningitis associated with Sweet's Syndrome is presented. Both entities have been described in association with several other chronic systemic inflammatory diseases and autoimmune conditions. To our knowledge the coexistence between Sweet's Syndrome and hypertrophic cranial pachymeningitis has not been reported up to date. We suggest a possible autoimmune or dysimmune mechanism in the pathogenesis of these two entities

    Full Text Available Sweet's syndrome is an acute febrile neutrophilic dermatosis which usually presents as an idiopathic disorder but can also be drug induced, associated with hematopoetic malignancies and myelodysplastic disorders, and more, infrequently, observed in autoimmune disorders. Sweet's syndrome has been reported in three cases of neonatal lupus, three cases of hydralazine-induced lupus in adults, and in nine pediatric and adult systemic lupus erythematosus (SLE patients. We describe three additional adult cases of Sweet's associated with SLE and provide a focused review on nondrug-induced, nonneonatal SLE and Sweet's. In two of three new cases, as in the majority of prior cases, the skin rash of Sweet's paralleled underlying SLE disease activity. The pathogenesis of Sweet's remains elusive, but evidence suggests that cytokine dysregulation may be central to the clinical and pathological changes in this condition, as well as in SLE. Further research is needed to define the exact relationship between the two conditions.

    Sweet syndrome is the most representative entity of febrile neutrophilic dermatoses. It typically presents in patients with pirexya, neutrophilia, painful tender erytomatous papules, nodules and plaques often distributed asymmetrically. Frequent sites include the face, neck and upper extremities. Affected sites show a characteristical neutrophilic infiltrate in the upper dermis. Its etiology remains elucidated, but it seems that can be mediated by a hypersensitivity reaction in which cytokines, followed by infiltration of neutrophils, may be involved. Systemic corticosteroids are the first-line of treatment in most cases. We present a concise review of the pathogenesis, classification, diagnosis and treatment update of this entity.

    Full Text Available The association of Crohn's disease (CD and Sweet's syndrome is rare and the presence of Sjögren's syndrome in Crohn's disease is even rarer, with only three reports found in the literature. We describe two cases of Crohn's disease associated with Sweet's syndrome, one of which is the first case of CD and Sweet's concomitantly associated with Sjögren's syndrome. Both cases responded rapidly to Infliximab therapy with complete resolution of the skin lesions.

  8. Acral manifestations of Sweet syndrome (neutrophilic dermatosis of the hands).

    Science.gov (United States)

    Wolf, Ronni; Tüzün, Yalçın

    Neutrophilic dermatosis of the hand (NDH) is a rare localized variant of the syndrome, originally described two decades ago by Strutton et al. The lesions of NDH and Sweet syndrome are similar, as indicated in the first report of NDH. Both diagnoses are characterized by an acute onset of fever, leukocytosis, and tender, erythematous infiltrated plaques. There are also bullae and ulceration in NDH, in contrast to Sweet syndrome, in which bullae are quite uncommon, especially at the early stages. Similar to Sweet syndrome, the majority of NDH patients are women (69%). Patients with NDH present with fever, peripheral neutrophilia, leukocytosis, and/or an elevated erythrocyte sedimentation rate or C-reactive protein level, but at a significantly lower rate than those in Sweet syndrome (33%). Similar to Sweet syndrome, NDH has been associated with the following conditions: Malignancies (particularly hematological [21%], most common of which is acute myelogenous leukemia, but many other malignancies as well), inflammatory bowel disease (19%), medication and vaccination-related eruptions, bacterial and viral infections, rheumatologic diseases, and others. The clues to the diagnosis of NDH are the same as for Sweet syndrome. Awareness of this diagnosis is important not only to avoid unnecessary medical and surgical therapy and to expediently initiate the administration of steroids for this highly responsive dermatosis, but also to conduct an appropriate workup to exclude associated diseases, especially malignancies.

    2009-03-01

    Sweet\\'s syndrome (SS), a rare reactive neutrophilic dermatosis, has been reported to occur in association with a variety of systemic disorders, categorized by von den Diesch into idiopathic, paraneoplastic, pregnancy and parainflammatory subgroups. The parainflammatory group has been well defined, and includes a wide spectrum of infectious triggers and disorders of immune dysregulation. To date, however, no cases of SS have been described in the context of common variable immunodeficiency (CVID). We report a case of paediatric-onset SS, previously reported as idiopathic, with a subsequent diagnosis of CVID.

Se caracteriza por cinco rasgos principales: 1 aparición brusca de placas eritemato-dolorosas en cara, cuello y extremidades; 2 fiebre; 3 leucocitosis polimorfonuclear; 4 denso infiltrado dérmico a predominio neutrofilico; 5 rápida respuesta al tratamiento esteroideo. Se puede clasificar en cinco grupos: idiopático, parainflamatorio, paraneoplásico, secundario a drogas y asociado a embarazo. En el 20% de los casos se asocia a enfermedades malignas, representando las hematológicas el 85% y los tumores sólidos el 15% restante. Se presenta una serie de siete casos de síndrome de Sweet asociado a neoplasias, diagnosticados durante el período 2002-2006, de los cuales seis correspondieron a enfermedades oncohematológicas y el restante a tumores sólidos. Como comentario de dicha casuística, se hace hincapié en la importancia del diagnóstico de este síndrome, debido a que puede anunciar la recaída del tumor o la progresión de la enfermedad de base. De esta manera, mediante el uso de métodos de diagnóstico y tratamiento oportunos, se lograría mejorar la calida de vida de estos pacientes. También debe tenerse en cuenta, que los pacientes oncológicos reciben múltiples medicaciones (factor estimulante de colonias, que pueden estar implicadas en la aparición de esta entidad, debiendo ser las mismas descartadas como posibles causas.Sweet's syndrome was described in 1964 by Robert Douglas Sweet, as an entity he named acute febrile neutrophilic dermatosis.

    Cohen Philip R

    2007-07-01

    Full Text Available Abstract Sweet's syndrome (the eponym for acute febrile neutrophilic dermatosis is characterized by a constellation of clinical symptoms, physical features, and pathologic findings which include fever, neutrophilia, tender erythematous skin lesions (papules, nodules, and plaques, and a diffuse infiltrate consisting predominantly of mature neutrophils that are typically located in the upper dermis. Several hundreds cases of Sweet's syndrome have been published. Sweet's syndrome presents in three clinical settings: classical (or idiopathic, malignancy-associated, and drug-induced. Classical Sweet's syndrome (CSS usually presents in women between the age of 30 to 50 years, it is often preceded by an upper respiratory tract infection and may be associated with inflammatory bowel disease and pregnancy. Approximately one-third of patients with CSS experience recurrence of the dermatosis. The malignancy-associated Sweet's syndrome (MASS can occur as a paraneoplastic syndrome in patients with an established cancer or individuals whose Sweet's syndrome-related hematologic dyscrasia or solid tumor was previously undiscovered; MASS is most commonly related to acute myelogenous leukemia. The dermatosis can precede, follow, or appear concurrent with the diagnosis of the patient's cancer. Hence, MASS can be the cutaneous harbinger of either an undiagnosed visceral malignancy in a previously cancer-free individual or an unsuspected cancer recurrence in an oncology patient. Drug-induced Sweet's syndrome (DISS most commonly occurs in patients who have been treated with granulocyte-colony stimulating factor, however, other medications may also be associated with DISS. The pathogenesis of Sweet's syndrome may be multifactorial and still remains to be definitively established. Clinical and laboratory evidence suggests that cytokines have an etiologic role. Systemic corticosteroids are the therapeutic gold standard for Sweet's syndrome. After initiation of treatment

    Sweet's syndrome (SS) is a neutrophilic dermatosis disorder of unknown aetiology, characterised by acute fever, neutrophilia, painful erythematous papules, nodules and plaques, and an infiltrate consisting predominantly of mature neutrophils in the upper dermis. Classical SS is a rare extra-intestinal manifestation of inflammatory bowel disease (IBD). It is more common in Crohn's disease than in ulcerative colitis (UC). There is a predilection for women, and for patients with colonic disease and active IBD. We report the case of a 39-year-old woman with a flare of moderate severity UC treated with mesalazine who presented with a 5-day history of acute fever, painful papules and plaques on forearms and legs, episcleritis and cervical pain. Skin biopsies showed papillary dermis inflammatory cell infiltration composed mainly of neutrophils, without evidence of leukocytoclastic vasculitis or panniculitis, compatible with SS. The patient had an excellent response to systemic corticosteroids. Symptoms promptly improved and skin lesions resolved after 7 weeks. 2016 BMJ Publishing Group Ltd.

    Ulcerative colitis is occasionally complicated by dermatological disorders presenting as extra-intestinal manifestations, including erythema nodosum and pyoderma gangrenosum. Sweet's syndrome is considered to be a rare cutaneous disease in patients with ulcerative colitis. To date, only 17 cases of Sweet's syndrome complicating ulcerative colitis have been reported in the English literature. Here, we report a case of a 41-year-old male who had been suffering from ulcerative colitis for 20 years. He was admitted to hospital with hematochezia, diarrhea and fever, and painful erythematous nodules on the face and arms. Histological examination of skin biopsies showed inflammatory cell infiltration composed mainly of neutrophils without evidence of necrotizing vasculitis, and the condition was diagnosed as Sweet's syndrome. The patient was treated with prednisolone and leukocytapheresis and the erythematous nodules on the skin, as well as the abdominal symptoms and endoscopic findings of ulcerative colitis, immediately improved. In this paper we report on this case and review the literature concerning ulcerative colitis and Sweet's syndrome.

    Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to neoplasm. Paraneoplastic syndromes may be the first or the most prominent manifestations of cancer. Wilm's tumor is the most frequent pediatric renal malignancy and usually presents with abdominal mass. Unusual presentations like acquired von Willebrand disease, sudden death due to pulmonary embolism and Cushing syndrome have been described in the literature. Cushing syndrome, as the presenting symptom of a malignant renal tumor in children, is a very rare entity. Few case reports are available in the literature exploring the option of preoperative chemotherapy as well as upfront nephrectomy. We report a rare case of paraneoplastic Cushing syndrome due to a Wilm's tumor. Based on gradual decrease of postoperative weight, blood pressure, serum adrenocorticotropic hormone, and plasma cortisol levels, along with histological confirmation of Wilm's tumor, paraneoplastic Cushing syndrome due to Wilm's tumor was confirmed.

Methods : From February to September 2010, the number of patients with Carpal Tunnel Syndrome who volunteered for this clinical study was 16 and 7 out of 16 patients complained both hands. Total 23 cases of hands were randomly divided by 2 groups. We injected Sweet Bee Venom Pharmacopuncture on PC7(Daereung twice a week for 4weeks for experimental group(n=11, and Scolopendrid Pharmacopuncture with the same methods for control group(n=12. One case was dropped out due to itchiness of allergic response in the experimental group. Improvement of the symptoms was evaluated by Visual Analogue Scale, Pain Rating Scale, Tinel’s sign, Phalen’s sign and Nerve Conduction Velocity. Nerve Conduction Velocity was checked at baseline and the end of the trial and others were checked at baseline, after 2 and 4 weeks. Results : Both groups showed significant improvement in Visual Analogue Scale, Pain Rating Scale, but no significant difference between two groups. Only the control group showed significant reduction of the‘ poitive response’in the Tinel’s sign and Phalen’s sign. However, no groups improved in Nerve Conduction Velocity. Conclusions : These results showed that Sweet Bee Venom Pharmacopuncture and Scolopendrid Pharmacopuncture could decrease the symptoms of Carpal Tunnel Syndrome. Further studies will be required to examine more cases for the long period and use more various concentration and amount pharmacopuncture for the effect on Carpal Tunnel Syndrome.

    Sweet's syndrome is rare acute febrile neutrophilic dermatosis whose onset is either idiopathic or associated with other underlying conditions, such as infections, autoimmune diseases, pregnancy, use of certain medications, or malignancy. We report the case of a young male with known history of ulcerative colitis and abrupt onset of high fever, malaise, blurred vision and eruption of painful erythematous nodules and papules, localized on the head, neck, trunk and upper limbs. Ophthalmological examination established the diagnosis of anterior uveitis. Inflammatory markers were positive. Histological examination of skin lesions revealed a dense neutrophilic infiltrate of the dermis. Clinical, laboratory and histological findings were suggestive for the diagnosis of Sweet's syndrome and uveitis on a background of ulcerative colitis. Systemic and ophthalmic administration of corticotherapy leads to a prompt resolution of symptoms and inflammatory syndrome. The particularity of this case is the occurrence of two simultaneous extraintestinal manifestations in a young male with inflammatory bowel disease and colonic involvement. Although a relatively rare condition, Sweet's syndrome should be considered as a differential diagnosis in patients with acute onset of high fever and skin rash, as it may have notable internal involvement and can be easily treated.

    Sweet syndrome is a neutrophilic dermatosis that may be categorized into classic, malignancy-associated, and drug-induced subtypes. Few studies have systematically analyzed this rare disorder. To describe the clinicopathologic characteristics and treatment of Sweet syndrome and identify characteristics associated with concurrent malignancy. We retrospectively reviewed patients with Sweet syndrome at the University of Pennsylvania from 2005 to 2015. We identified 83 patients (mean age, 57 years; 51% male) with Sweet syndrome: 30% with the classic form, 44% with the malignancy-associated form, 24% with the drug-induced form in the setting of malignancy, and 2% with the drug-induced form. Acute myeloid leukemia was the most common malignancy (in 24 of 83 patients [29%]). Filgrastim was the most common medication (used in 8 of 83 patients [10%]).

    Full Text Available At low concentrations, Cu is considered as an essential micronutrient for plants and as a constituent and activator of several enzymes. However, when in excess, Cu can negatively affect plant growth and metabolism. Therefore, the aim of this study was to evaluate physiological responses of sweet potato plants at different Cu concentrations by measuring morphological parameters, antioxidant metabolism, stomatal characteristics, and mineral profile. For this purpose, sweet potato plants were grown hydroponically in complete nutrient solution for six days. Then, the plants were transferred to solutions containing different Cu concentrations, 0.041 (control, 0.082, and 0.164 mM, and maintained for nine days. The main effect of increased Cu concentration was observed in the roots. The sweet potato plants grown in 0.082 mM Cu solution showed increased activity of antioxidant enzymes and no changes in growth parameters. However, at a concentration of 0.164 mM, Cu was transported from the roots to the shoots. This concentration altered morpho-anatomical characteristics and activated the antioxidant system because of the stress generated by excess Cu. On the basis of the results, it can be concluded that the sweet potato plants were able to tolerate Cu toxicity until 0.082 mM.

    A 33-year old pregnant patient (pregnancy week 15) with a past medical history of ulcerative colitis with onset of the disease following the birth of her first child was admitted to the hospital with symptoms of weight loss, pyrexia, leukocytosis and bloody and mucous diarrhoea. Total ileocolonoscopy revealed an acute flare of ulcerative colitis. Within a few days, tender erythematous skin lesions occurred and were histologically proven to be neutrophilic dermatosis. Treatment with highly-dosed prednisone led to a complete remission of both cutaneous and intestinal manifestations. Both pathogenic entities are associated with similar immunological alterations, such as comparable cytokine and chemokine release patterns and recruitment of inflammatory cells. Recent data also indicates that proinflammatory cytokine levels are elevated in pregnancy, which might be pivotal in the pathogenesis and the severity of intestinal and extraintestinal symptoms. We present and discuss a diagnostic algorithm and an overall therapeutic rationale for Sweet's syndrome. Copyright Georg Thieme Verlag KG Stuttgart. New York.

Clinical symptoms realized a Nicolau syndrome, which is characterized by immediate pain, livedoid pattern and a few days later by the appearance of scabs and skin necrosis. This type of complication is rare, but may be dramatic and injectors must be aware of that. A thorough knowledge of facial anatomy is mandatory to avoid the risky facial areas. The use of a flexible cannula instead of a sharp needle has much less risk of hurting vessels and must be preferred. The support of the patient is discussed and a treatment protocol is proposed.

    Full Text Available Background Lacunar syndrome not due to lacunar infarct is poorly characterised. This single centre, retrospective study was conducted to describe the clinical characteristics of patients with lacunar syndrome not due to lacunar infarct and to identify clinical predictors of this variant of lacunar stroke. Methods A total of 146 patients with lacunar syndrome not due to lacunar infarction were included in the "Sagrat Cor Hospital of Barcelona Stroke Registry" during a period of 19 years (1986-2004. Data from stroke patients are entered in the stroke registry following a standardized protocol with 161 items regarding demographics, risk factors, clinical features, laboratory and neuroimaging data, complications and outcome. The characteristics of these 146 patients with lacunar syndrome not due to lacunar infarct were compared with those of the 733 patients with lacunar infarction. Results Lacunar syndrome not due to lacunar infarct accounted for 16.6% (146/879 of all cases of lacunar stroke. Subtypes of lacunar syndromes included pure motor stroke in 63 patients, sensorimotor stroke in 51, pure sensory stroke in 14, atypical lacunar syndrome in 9, ataxic hemiparesis in 5 and dysarthria-clumsy hand in 4. Valvular heart disease, atrial fibrillation, sudden onset, limb weakness and sensory symptoms were significantly more frequent among patients with lacunar syndrome not due to lacunar infarct than in those with lacunar infarction, whereas diabetes was less frequent. In the multivariate analysis, atrial fibrillation (OR = 4.62, sensorimotor stroke (OR = 4.05, limb weakness (OR = 2.09, sudden onset (OR = 2.06 and age (OR = 0.96 were independent predictors of lacunar syndrome not due to lacunar infarct. Conclusions Although lacunar syndromes are highly suggestive of small deep cerebral infarctions, lacunar syndromes not due to lacunar infarcts are found in 16.6% of cases. The presence of sensorimotor stroke, limb weakness and sudden onset in a patient

    To investigate whether palatable sweet foods have a beneficial effect on chronic stress-induced colonic motility and inflammatory cytokines. Adult male rats were divided into 3 groups: control (CON, n = 5), chronic variable stress with chow (CVS-A, n = 6), and chronic variable stress with chow and sweet food (CVS-B, n = 6). The rats were fed standard rodent chow as the chow food and/or AIN-76A as the sweet food. A food preference test for AIN-76A was performed in another group of normal rats (n = 10) for twelve days. Fecal pellet output (FPO) was measured for 6 wk during water bedding stress in the CVS groups. The weight of the adrenal glands, adrenocorticotropic hormone (ACTH) and corticosterone levels in plasma were measured. The expression levels of transforming growth factor-β, interleukin (IL)-2, and interferon-gamma (IFN-γ) were measured in the distal part of colonic tissues and plasma using Western blot analysis. In sweet preference test, all rats initially preferred sweet food to chow food. However, the consumption rate of sweet food gradually decreased and reduced to below 50% of total intake eight days after sweet food feeding. Accumulated FPO was higher in the CVS-A group compared with the CVS-B group over time. All stress groups showed significant increases in the adrenal to body weight ratio (CVS-A, 0.14 ± 0.01; CVS-B, 0.14 ± 0.01) compared with the control group (0.12 ± 0.01, P food ingestion during CVS might have an effect on the reduction of stress-induced colonic hyper-motility and pro-inflammatory cytokine production in rats.

    Full Text Available Abstract Introduction Anton's syndrome describes the condition in which patients deny their blindness despite objective evidence of visual loss, and moreover confabulate to support their stance. It is a rare extension of cortical blindness in which, in addition to the injury to the occipital cortex, other cortical centres are also affected, with patients typically behaving as if they were sighted. Case presentation We present a case report of an 83-year-old white woman with cortical blindness as a result of bilateral occipital lobe infarcts. Despite her obvious blindness, illustrated by her walking into objects, the patient expressed denial of visual loss and demonstrated confabulation in her accounts of her surroundings, consistent with a diagnosis of Anton's syndrome. Conclusions A suspicion of cortical blindness and Anton's syndrome should be considered in patients with atypical visual loss and evidence of occipital lobe injury. Cerebrovascular disease is the most common cause of Anton's syndrome, as in our patient. However, any condition that may result in cortical blindness can potentially lead to Anton's syndrome. Recovery of visual function will depend on the underlying aetiology, with cases due to occipital lobe infarction after cerebrovascular events being less likely to result in complete recovery. Management in these circumstances should accordingly focus on secondary prevention and rehabilitation.

    Full Text Available BACKGROUND Although pulmonary tuberculosis is a common disease in India, tuberculosis of right middle lobe is infrequent. Tuberculosis of the right middle lobe leading to chronic collapse is a cause of Right Middle Lobe syndrome. METHODS The patients attended Pulmonary Medicine Outdoor at Era’s Lucknow Medical College, Lucknow from April 2015 to March 2016. The purpose of this study is to describe the clinicoradiological features of patients of middle lobe syndrome due to tuberculosis. All patients presented with cough with or without expectoration, fever, chest pain, haemoptysis and constitutional symptoms like loss of appetite and weight. Chest X-ray PA view revealed ill-defined opacity abutting the right cardiac border. HRCT thorax was done in each case. The diagnosis of tuberculous aetiology was based on (1 History of chronic cough and fever, not responding to antibiotic therapy and constitutional symptoms, (2 A positive tuberculin test using 2 TU of PPD RT 23 and (3 Detection of acid fast bacilli by direct smear or Mycobacterium tuberculosis by polymerase chain reaction in bronchoalveolar lavage. RESULTS Out of 10 patients, 4 (40% were males and 6 (60% were females. The mean ages of the males were 55.8 years and females were 60.8 years and overall mean age was 59 years. Most of the patients were females and belonged to the middle age and old age group. ATT was started in all the patients. CONCLUSIONS Right middle lobe syndrome predominantly affects the older population and the female gender. Although tuberculosis is a common disease in India, Middle Lobe Syndrome is a very rare presentation of the disease. Due to non-specific symptoms and usually normal chest X-ray PA view in Right Middle Lobe Syndrome, we should keep a high index of suspicion to diagnose the condition.

    Sodium valproate (VPA) is commonly used to treat epilepsy in children. Renal dysfunction is a rare side eff ect but can present as tubulopathy such as Fanconi syndrome. We report on an 8-year-old disabled girl with myoclonic epilepsy who was referred for investigation of recurrent low impact fractures of the distal femur which were initially thought to be caused by her severe immobility. However, she was subsequently found to have hypophosphataemia secondary to Fanconi syndrome due to prolonged VPA use. After VPA withdrawal renal function and serum phosphate levels normalised and X-rays improved dramatically. The possibility of drug-induced osteoporosis and fractures should always be considered in disabled children, even in the presence of severe immobility.

    Constipation is a common health problem that adversely affects quality of life and the prognosis of hospitalized patients with acute coronary syndromes (ACS). The purpose of this study was to develop and test the sweet potato/footbath/acupressure massage (SFA) intervention as a safe treatment for prevention of constipation and to increase satisfaction with bowel emptying in hospitalized patients with ACS. The study was a prospective, randomized controlled trial with a sample of 93 patients (SFA group, n = 44; usual care group, n = 49). Patients in the SFA group received SFA intervention combined with usual care. The results showed that there were statistical differences between the two groups in terms of (1) the incidence of constipation; (2) the use of laxatives and enemas; (3) patients' subjective satisfaction with their bowel emptying during hospitalization; and (4) sensation of incomplete evacuation and anorectal obstruction/blockade. The SFA intervention was more effective, economical, and practical than usual care alone in managing constipation and satisfaction with defecation in patients hospitalized with ACS.

    We present a case of a patient with Anton's syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton's syndrome, he might have had Charles Bonnet syndrome, characterized by both visual loss and hallucinations. Anton syndrome, is not so frequent condition and is most commonly caused by ischemic stroke. In this particular case, the patient had successive bilateral occipital ischemia as a result of massive stenoses of head and neck arteries.

    Full Text Available Envenoming syndrome from Africanized bee stings is a toxic syndrome caused by the inoculation of large amounts of venom from multiple bee stings, generally more than five hundred. The incidence of severe toxicity from Africanized bee stings is rare but deadly. This report reveals that because of the small volume of distribution, having fewer stings does not exempt a patient from experiencing an unfavorable outcome, particularly in children, elderly people or underweight people.

    Full Text Available Some diseases, such as Gitelman′s syndrome, Bartter′s syndrome, and primary hyperaldosteronism (Conn′s syndrome, may bear some similar clinical and laboratory findings. Their treatment modalities being different from one another, the need for a scrupulous diagnostic evaluation arises as far as clinical practice is concerned. In this report, we present a patient with Conn′s syndrome who was initially considered to have Gitelman′s syndrome due to displaying a few overlapping features of both diseases. We also give an account of the hardships encountered during the diagnostic evaluation.

    The elongation or calcification of the stylohyoid ligament that leads to pressure symptoms, or entrapment of nearby glossopharyngeal nerve or carotid artery, is known as Eagle syndrome. A PubMed search leads to finding of rare fatality among the 49 reported cases. In the present case, the deceased was a 40-year-old male who choked on his food. We hypothesise that the impaction of food in the upper respiratory tract, as well as the inability to intubate the person, were both the result of the calcified stylohyoid ligament.

    2014-10-01

    Full Text Available Our aims were to describe the prevalence of pulmonary hypertension in patients with acute respiratory distress syndrome (ARDS, to characterize their hemodynamic cardiopulmonary profiles, and to correlate these parameters with outcome. All consecutive patients over 16 years of age who were in the intensive care unit with a diagnosis of ARDS and an in situ pulmonary artery catheter for hemodynamic monitoring were studied. Pulmonary hypertension was diagnosed when the mean pulmonary artery pressure was >25 mmHg at rest with a pulmonary artery occlusion pressure or left atrial pressure <15 mmHg. During the study period, 30 of 402 critically ill patients (7.46% who were admitted to the ICU fulfilled the criteria for ARDS. Of the 30 patients with ARDS, 14 met the criteria for pulmonary hypertension, a prevalence of 46.6% (95% CI; 28-66%. The most common cause of ARDS was pneumonia (56.3%. The overall mortality was 36.6% and was similar in patients with and without pulmonary hypertension. Differences in patients' hemodynamic profiles were influenced by the presence of pulmonary hypertension. The levels of positive end-expiratory pressure and peak pressure were higher in patients with pulmonary hypertension, and the PaCO2 was higher in those who died. The level of airway pressure seemed to influence the onset of pulmonary hypertension. Survival was determined by the severity of organ failure at admission to the intensive care unit.

    Full Text Available Combined clinical presentation of hemifacial spasm and ipsilateral trigeminal neuralgia is also known as painful tic convulsif (PTC. It is a rare condition and the most common cause is vascular compression. Vertebrobasilar dolichoectasia (VBD is characterized by dilated and tortuous vertebral and basilar arteries. VBD is an uncommon and rarely reported cause of PTC. Magnetic resonance imaging (MRI, due to its inherent excellent contrast resolution, is an excellent modality for demonstrating the nerve compression by dilated and tortuous vessels seen in this condition. For this purpose, 3D MRI sequences are especially useful like constructive interference in steady state (CISS and MR angiography. Both of these have been reported to be helpful in the diagnosis of this condition. We report a case of PTC in which we were able to document facial and trigeminal nerve compression by VBD on MRI, using CISS and time-of-flight MR angiography.

  13. Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma

    Directory of Open Access Journals (Sweden)

    Avradip Santra

    2016-07-01

    Full Text Available Superior vena cava (SVC syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e.g., malignancy. Here, an unusual case of sudden onset SVC syndrome has been reported, which on initial radiologic evaluation was found to have a lung nodule without any significant mediastinal mass or adenopathy compressing SVC. Subsequent investigation with Doppler ultrasonography of the neck showed thrombosis in the right internal jugular, right subclavian and right brachiocephalic vein, which was responsible for SVC syndrome. Histopathological evaluation of lung nodule confirmed presence of an adenocarcinoma. Therefore, venous thromboembolism as a paraneoplastic syndrome should be kept in mind while evaluating a case of SVC obstruction in a cancer patient. Management of the underlying disease is of prime importance in such cases and anticoagulation is the mainstay of therapy. Ability to identify paraneoplastic syndrome may have a significant effect on clinical outcome, ranging from early diagnosis to improved quality of life of the patient.

    Full Text Available Background. Shock syndrome is an acute tissue hypoperfusion. Early diagnosis and adequate symptomatic and causal treatment are mandatory. In spite of different etiologies (dehidration, bleeding, heart failure, sepsis, clinical signs and symptomes are similar (hypotension, tachicardia, tachipnoe, pallor, cold and wet skin, oliguria and metabolic acidosis. Rarely, the shock syndrome is the consequence of the adrenal insufficiency due to hypopituitarism caused by brain tumor where early treatment with hydrocortisone is urgent.Methods. This article presents a patient with a shock syndrome and multiorgan failure. Endocrinological testing and brain CT demonstrated an endocrinologically inactive tumor of hypophysis. The tumor was growing into adjacent hypophyseal tissue and causing hypopituitarism with secondary hypothyroidism and adrenal insufficiency and deficit of both gonadotropins and growth hormone.Conclusions. Primary or secondary adrenal insufficiency are among rare causes of shock syndrome. Whenever it is suspected, estimation of serum levels of cortisol and ACTH is necessary and immediate treatment with hydrocortisone should be instituted.

    Summary Background: Sjögren syndrome (SS) is an autoimmune-lymphoproliferative disorder characterized by mononuclear cell infiltration of exocrine glands. Clinically, Sjögren syndrome (SS) has a wide spectrum, varying from autoimmune exocrinopathy to systemic involvement. There have been few cases reporting that primary SS developed with distal renal tubular acidosis clinically. Case Report: Here, we present a case with primary Sjögren syndrome accompanied by hypopotassemic paralysis due to renal tubular acidosis. Severe hypopotassemia, hyperchloremic metabolic acidosis, alkaline urine and disorder in urinary acidification test were observed in the biochemical examination of the 16-year-old female patient, who had applied to our clinic for extreme loss of muscle force. After the examinations it was determined that the patient had developed Type 1 RTA (distal RTA) due to primary Sjögren syndrome. Potassium and alkaline replacement was made and an immediate total recovery was achieved. Conclusions: Hypopotassemic paralysis due to primary Sjögren syndrome is a rare but severe disorder that could lead to death if not detected early and cured appropriately. Thus, effective treatment should be immediately initiated in cases where severe hypopotassemia is accompanied by metabolic acidosis, and the cases should also be examined for extraglandular involvement of SS.

    2009-09-01

    Full Text Available Cushing syndrome is rare in infancy and usually due to an adrenocortical tumor (ACT. We report an infant with Cushing syndrome due to adrenocortical carcinoma. The patient presented at six months of age with a three-month history of growth failure, rapid weight gain, acne, and irritability. Physical examination showed obesity, hypertension, and Cushingoid features. Biochemical evaluation showed very high serum cortisol, mildly elevated testosterone, and suppressed ACTH. Abdominal MRI revealed a heterogeneous right adrenal mass extending into the inferior vena cava. Evaluation for metastases was negative. The tumor was removed surgically en bloc. Pathologic examination demonstrated low mitotic rate, but capsular and vascular invasion. She received no adjuvant therapy. Her linear growth has improved and Cushingoid features resolved. Hormonal markers and quarterly PET scans have been negative for recurrence 24 months postoperatively. In conclusion, adrenocortical neoplasms in children are rare, but should be considered in the differential diagnosis of Cushing syndrome.

    Full Text Available Orbital apex syndrome is commonly been thought to have a poor prognosis. Many cases of this syndrome have been reported to be caused by paranasal sinus mycosis. We encountered a very rare case (60-year-old woman of sinusitis with orbital apex syndrome due to Pseudomonas aeruginosa infection. She had received insulin and dialysis for diabtes and diabetic nephropathy, moreover anticoagulants after heart by-pass surgery. She underwent endoscopic sinus operation and was treated with antibiotics, but her loss of left vision did not improve. Recently, sinusitis cases due to Pseudomonas aeruginosa were reported to be a increasing. Therefore, we should consider the possibility of Pseudomonas aeruginosa as well as mycosis as infections of the sinus, especially inpatients who are immunocompromised body.

    An informative patient with a MCA/MR syndrome consisting of developmental delay, prenatal onset growth delay, microcephaly, distinctive face, iris coloboma, and a congenital heart defect was found, on chromosome analysis, to have the following complement: 46,XY,rec(4) dup(4p) inv(4)(p14q35.1) mat. He has a partial 4p trisomy/distal 4q deletion due to an unbalanced pericentric inversion inherited from his mother. Dup (4p) trisomy was originally described by Wilson et al. [1970: Am J Hum Genet 22:679-690] in a similar case with the same chromosome 4 inversion. To date, at least 85 cases of dup (4p) syndrome have been published, mostly due to unbalanced translocations. Recent articles suggest that the phenotype is hard to recognize clinically due to the lack of specificity of findings. In contrast, 4p trisomy due to an unbalanced pericentric inversion of chromosome 4(p14q35), i.e., the recombinant 4 syndrome observed in our patient, appears to be a discrete entity with relatively consistent features. In total there are four other kindreds described in the literature with this inversion, and the phenotype seems recognizable. Thus, we suggest that recombinant 4 syndrome is a discrete entity among 4p trisomy patients. Copyright 2002 Wiley-Liss, Inc.

    Adenocorticotropic hormone (ACTH)-dependent Cushing's syndrome in infancy is extremely rare. We describe the case of a sacro-coccygeal ectopic ACTH-secreting immature teratoma in an infant who also presented the triad of defects characteristic of Currarino syndrome. A girl was born with a large immature teratoma in the sacro-coccygeal region associated with anal atresia. At the age of 7 days, the concentration of α-fetoprotein (AFP) was above the age-specific normal range. Two non-radical surgical excisions of the tumour were performed. At the age of 7 months, she developed polyphagia, acne, hirsutism, hypertension and hypokalemia with elevated ACTH and absence of serum cortisol circadian rhythm. Immunostaining of tumour tissue showed ACTH-immunoreactive cells. Due to unsuccessful therapy with ketoconazole and resistance to antihypertensive medications [blood pressure (BP) 210/160 mmHg], metyrapone was administered, which controlled her ACTH and cortisol levels in the normal range. Following further removal of tumour bulk after three operations during the first year of life, there was a decrease of BP to normal values. A rare case of ectopic ACTH syndrome causing Cushing's syndrome in infancy in the context of Currarino syndrome is reported. Radical surgery has resulted in excision of the tumour and current control of Cushing's syndrome.

    Takotsubo syndrome is characterized by predominantly medial-apical transient left ventricular dysfunction, which is typically triggered by physical or emotional stress. The present article reports the case of a 61-year-old female patient presenting with dizziness, excessive sweating, and sudden state of ill feeling following an episode involving intense emotional stress. The physical examination and electrocardiogram were normal upon admission, but the troponin I and creatine kinase-MB concentrations were increased. Acute myocardial infarction without ST segment elevation was suspected, and coronary angiography was immediately performed, which showed severe diffuse left ventricular hypokinesia, medial-apical systolic ballooning, and a lack of significant coronary injury. The patient was referred to the intensive care unit and was successfully treated with supportive therapy. As this case shows, Takotsubo syndrome might simulate the clinical manifestations of acute myocardial infarction, and coronary angiography is necessary to distinguish between both myocardial infarction and myocardial infarction in the acute stage. The present patient progressed with spontaneous resolution of the ventricular dysfunction without any sequelae.

  7. Iliac Vein Compression Syndrome due to Bladder Distention Caused by Urethral Calculi

    Full Text Available We report a rare case of iliac vein compression syndrome caused by urethral calculus. A 71-year-old man had a history of urethral stenosis. He complained of bilateral leg edema and dysuria for 1 week. Physical examination revealed bilateral distention of the superficial epigastric veins, so obstruction of both common iliac veins or the inferior vena cava was suspected. Plain abdominal computed tomography showed a calculus in the pendulous urethra, distention of the bladder (as well as the right renal pelvis and ureter, and compression of the bilateral common iliac veins by the distended bladder. Iliac vein compression syndrome was diagnosed. Bilateral iliac vein compression due to bladder distention (secondary to neurogenic bladder, benign prostatic hyperplasia, or urethral calculus as in this case is an infrequent cause of acute bilateral leg edema. Detecting distention of the superficial epigastric veins provides a clue for diagnosis of this syndrome.

    Full Text Available Purpose: Midline structural defects in the neural axis can give rise to neuro-ophthalmic symptoms. We report a rare case of keyhole aqueduct syndrome presenting after two years of severe cough due to gastroesophageal reflux disease. Observations: A 58-year-old woman with a 2-year history of daily, severe cough presented to the neuro-ophthalmology clinic with progressive diplopia and oscillopsia. Examination revealed a 1–2 Hz down-beating nystagmus in primary gaze that worsened with left, right, and down gazes. Gaze evoked nystagmus and mild paresis were also seen with up gaze. There was an incomitant left hypertropia due to skew deviation that worsened with right and up gazes and improved with down gaze. She also had a right-sided ptosis and a 3 mm anisocoria not due to cranial nerve 3 paresis or Horner's syndrome. Brain magnetic resonance imaging showed a 1.5 mm × 11.7 mm × 6 mm midline cleft in the ventral midbrain communicating with the cerebral aqueduct, consistent with keyhole aqueduct syndrome. Her nystagmus and diplopia improved with oral acetazolamide treatment, at high doses of 2500–3000 mg per day. Conclusions and importance: We report the first case of midbrain keyhole aqueduct syndrome with ocular motor and other neuro-ophthalmic manifestations associated with severe cough. Although her cough was effectively treated and intracranial pressure measurement was normal, her ophthalmic symptoms continued to progress, which is common in previous cases reported. Treatment with acetazolamide led to significant improvement, supporting the use of acetazolamide in this rare condition.

    The prevalence of coronary artery disease is on the rise as the life expectancy of the population increases. However, treatment of acute coronary syndrome in the elderly patients has its own problems that have not been thoroughly addressed in the clinical trials. Since these patients are generally fragile and have multiple co-morbidities, the course of acute coronary syndrome can frequently be complicated. Infection, which co-exists either at the initial presentation or is acquired during the hospital stay, is a condition about which there is little published data. Therefore, in our study, we wanted to assess the impact of infection on mortality in octogenarians who have acute coronary syndrome METHODS: We retrospectively analyzed the data of 174 octogenarians who had been admitted to the coronary care unit with acute coronary syndrome. All-cause mortality was defined as the primary endpoint of the study. Overall 53 octogenarian patients (30.5%) had an infection along with acute coronary syndrome. The mean duration of follow-up was 10 months (1-25 months). Both in-hospital and long-term mortality were higher in these patients (18.9% vs 6.6%, p = 0.01; 52.8% vs 27.5%, p < 0.01; respectively). Kaplan-Meier analysis also showed lower cumulative survival. (p [log-rank] = 0.002). In multivariate Cox regression analysis; undergoing coronary angiography, infection (HR 1.96, 95% CI 1.15-3.34, p = 0.01), left ventricular ejection fraction and maximum C reactive protein levels were found as independent predictors of long-term survival. Infection in octogenarians who were admitted due to acute coronary syndrome was frequent and increased their mortality substantially. Copyright © 2018 Elsevier B.V. All rights reserved.

    2014-12-01

    Three sweet potato cultivars (TNG57, TNG66, and TNG73), provided by the Taiwanese Agricultural Research Institute (TARI), were stored at either 15 °C or under ambient conditions (23.8 ~ 28.4 °C and 77.1 ~ 81.0 % of relative humidity). Sweet potato roots were randomly chosen from each replicate and evaluated for measurement of weight loss, sugar content analysis, and sprouting after 0, 14, 24, 48, 56, 70, 84, and 98 days of storage. Fresh sweet potato roots were baked at 200 °C for 60 min then samples were taken for sugar analysis. After 14 days of ambient condition storage, the sprouting percentages for TNG57, TNG66, and TNG73 were 100, 85, and 95 % respectively. When sweet potatoes were stored at 15 °C, the weight loss became less and no sweet potato root sprouted after 14 days of storage. Because manufacturers can store sweet potatoes at 15 °C for almost 2 month without other treatments, the supply capacity shortage in July and September can be reduced. The total sugar content slowly increased along with increasing the storage time. After baking, the total sugar content of sweet potatoes significantly increased due to the formation of maltose. Maltose became the major sugar of baked sweet potatoes. Raw sweet potatoes stored at 15 °C had higher total sugar contents after baking than those stored under ambient conditions. Raw sweet potatoes were recommended to be stored at 15 °C before baking.

    Background: Recurrent pregnancy loss is a major health problem effecting 1 to 2% of women of reproductive age. Its causes range from chromosomal abnormalities to endocrinological factors and thrombophilia related factors. Treating thrombophilia s especially anti phospholipid syndrome with low dose aspirin and low molecular weight heparin improves foetal outcome. This study will add local data to already existing knowledge. Method: Sixty selected patients from gynaecology OPD of Aero Hospital with clinical and/or serological findings of anti phospholipid syndrome from February 2009 to January 2011 were given aspirin 75 mg once daily and enoxaparine 40 mg subcutaneously once daily from 6 - 8 weeks to 35 and 37 weeks respectively. Results : Ninety-three percent of patients achieved live birth. Out of these 75% patients delivered at term and 18% had preterm delivered. Four (7%) had early pregnancy loss and only one had early neonatal death due to extreme prematurity. None of patients experienced any major hemorrhagic complications . Conclusion: Use of low dose aspirin and low molecular weight heparin is safe in pregnancy and improve foetal outcome in patients with recurrent pregnancy loss due to anti phospholipids syndrome.

    To report a case of Cushing syndrome due to apparently sporadic primary pigmented nodular adrenal disease in a young woman. We describe the clinical, biochemical, radiologic, and histologic findings of Cushing syndrome due to the rare condition of primary pigmented nodular adrenal disease. A 30-year-old woman presented with a 2-year history of worsening itch without rash over her shoulders and arms and weight gain, particularly around the abdomen and face. Careful questioning did not elicit any history of exogenous glucocorticoid use (systemic or topical), including hydrocortisone. On examination, the patient had a slightly rounded and plethoric face, a small buffalo hump, central adiposity, and thin skin with a few small striae on her inner thighs. No features of the Carney complex were observed. Investigations showed hypercortisolism with suppressed corticotropin and normal adrenal imaging despite documentation of enlarged adrenal glands at removal. High-dose dexamethasone administration was followed by a decrease in urinary free cortisol excretion rather than a paradoxical rise as previously reported in primary pigmented nodular adrenal disease. No mutations were detected in the PRKAR1A gene. Primary pigmented nodular adrenal disease should be suspected in patients with corticotropin-independent Cushing syndrome who have normal adrenal imaging. The role of genetic testing in apparently sporadic cases is not established, but cumulative experience may be helpful in defining the frequency of PRKAR1A mutations.

  15. Multiple osteoblastomas in a child with Cushing syndrome due to bilateral adrenal micronodular hyperplasias

    2016-03-01

    Full Text Available Adrenocorticotropin-independent adrenal hyperplasias are rare diseases, which are classified into macronodular (>1 cm and micronodular (≤1 cm hyperplasia. Micronodular adrenal hyperplasia is subdivided into primary pigmented adrenocortical disease and a limited or nonpigmented form 'micronodular adrenocortical disease (MAD', although considerable morphological and genetic overlap is observed between the 2 groups. We present an unusual case of a 44-month-old girl who was diagnosed with Cushing syndrome due to MAD. She had presented with spotty pigmentation on her oral mucosa, lips and conjunctivae and was diagnosed with multiple bone tumors in her femur, pelvis and skull base at the age of 8 years. Her bone tumor biopsies were compatible with osteoblastoma. This case highlights the importance of verifying the clinicopathologic correlation in Cushing syndrome and careful follow-up and screening for associated diseases.

    Patients with resection of stomach and especially with Billroth II reconstruction (gastro jejunal anastomosis), are more likely to develop afferent loop syndrome which is a rare complication. When the afferent part is obstructed, biliary and pancreatic secretions accumulate and cause the distention of this part. In the case of a complete obstruction (rare), there is a high risk developing necrosis and perforation. This complication has been reported once in the literature. A 54-year-old Greek male had undergone a pancreato-duodenectomy (Whipple procedure) one year earlier due to a pancreatic adenocarcinoma. Approximately 10 months after the initial operation, the patient started having episodes of cholangitis (fever, jaundice) and abdominal pain. This condition progressively worsened and the suspicion of local recurrence or stenosis of the biliary-jejunal anastomosis was discussed. A few days before his admission the patient developed signs of septic cholangitis. Our case demonstrates a rare complication with serious clinical manifestation of the afferent loop syndrome. This advanced form of afferent loop syndrome led to the development of huge enterobiliary reflux, which had a serious clinical manifestation as cholangitis and systemic sepsis, due to bacterial overgrowth, which usually present in the afferent loop. The diagnosis is difficult and the interventional radiology gives all the details to support the therapeutic decision making. A variety of factors can contribute to its development including adhesions, kinking and angulation of the loop, stenosis of gastro-jejunal anastomosis and internal herniation. In order to decompress the afferent loop dilatation due to adhesions, a lateral-lateral jejunal anastomosis was performed between the afferent loop and a small bowel loop.

    A 6-year-old, castrated male ferret (Mustela putorius furo) was presented with progressive neurological signs consisting of a right-sided head tilt and ataxia. Neurological examination revealed hemiparesis and absence of proprioception on the right side, consistent with central vestibular syndrome. Measurement of blood glucose excluded hypoglycemia due to insulinoma. Contrast-enhanced computed tomography revealed the presence of an intracranial mass, consistent with either granuloma or neoplasia. Palliative treatment with prednisolone yielded no improvement. At postmortem examination, a final diagnosis of a choroid plexus papilloma originating from the fourth ventricle was made. This is the first report of such a tumor in a ferret.

    Herein we describe a case of microangiopathic antiphospholipid syndrome (MAPS) due to anti-phosphatidylserine/prothrombin complex (aPS/PT) IgM antibody successfully treated with rituximab. A significant correlation was observed between the clinical course and the aPS/PT IgM antibody titer, which can rise earlier before the appearance of clinical symptoms. Rituximab can be safely and effectively used for MAPS. Although detection of only aPS/PT IgM antibody is rare, aPS/PT IgM antibody might be associated with the pathogenesis of MAPS and might be a useful marker of disease activity. © 2017 Japan Pediatric Society.

    A 62-year-old man with well-controlled diabetes mellitus developed numbness of the bilateral feet and hands, followed by subacutely progressive weakness and amyotrophy of extremities. He became bed-ridden state, and dyspnea also appeared, so he was referred to our hospital. Physical examination revealed a lean man, with dark-reddish skin pigmentation, crabbed fingers, bilateral pretibial pitting edema, and bristles in extremities. Thoracoabdominal paradoxical respiration was observed and pulmonary vesicular sounds was decreased markedly in the both lungs. Laboratory data revealed hypoproteinemia, abnormalities of endocrine system, but M-protein was not detected. Serum vascular endothelial growth factor level was quite high. Chest radiography revealed elevation of the bilateral diaphragm, the % vital capacity (%VC) was 24%, and arterial blood gas analysis showed marked hypoxia with hypercapnia. These findings suggested that his respiratory failure was induced by bilateral diaphragmatic paralysis caused by bilateral phrenic nerve palsy due to Crow-Fukase syndrome. He became somnolent because of hypercapnic narcosis, so non-invasive positive pressure ventilation (NIPPV) was started. We treated him with intravenous immunoglobulin and oral corticosteroids therapies, and after these therapies, his symptoms were remarkably recovered and NIPPV became unnecessary soon. The most frequent causes of respiratory failure in Crow-Fukase syndrome are pleural effusion and pulmonary hypertension, and only two cases of this syndrome with respiratory failure caused by bilateral diaphragmatic paralysis were reported until now. When the patients with Crow-Fukase syndrome complain of dyspnea, we should take the diaphragmatic paralysis into consideration, which may be improved by appropriate therapies.

    Budd-Chiari syndrome (BCS) is a rare clinical entity characterized by post-sinusoidal portal hypertension caused by the obstruction to the hepatic vein outflow. The diagnosis is suggested by hepatic scintigraphy and is usually confirmed by hepatic venography, inferior vena cavography and biopsy. The scintigraphic finding of BCS caused by the obstruction of main hepatic vein has been reported to consist typically of hypertrophy of the caudate lobe with increased radionuclide accumulation. Such a typical finding has been accounted for by the fact that the venous outflow from the caudate lobe is preserved when the main hepatic vein is obstructed. But usually, the hepatic venous outflow from the caudate lobe is also obstructed in BCS due to inferior vena caval obstruction. So hepatic scintigraphic findings of BCS due to inferior vena caval obstruction show different findings as compared with the BCS due to hepatic vein obstruction. We evaluate the hepatic scintigrams of the 13 cases of BCS due to inferior vena caval obstruction and review the literatures. The results are as follows: 1) We cannot observe the caudate lobe hypertrophy with increased uptake, which is known as a classic finding in BCS due to hepatic vein obstruction. 2) The most prominent hepatic scintigraphic findings of BCS are nonhomogenous uptake in the liver with extrahepatic uptake in the all cases. 3) We can see cold areas at the superior aspect of right hepatic lobe in 7 cases (54%). This is a useful finding suggesting BCS due to inferior vena caval obstruction.

The results are as follows: 1) We cannot observe the caudate lobe hypertrophy with increased uptake, which is known as a classic finding in BCS due to hepatic vein obstruction. 2) The most prominent hepatic scintigraphic findings of BCS are nonhomogenous uptake in the liver with extrahepatic uptake in the all cases. 3) We can see cold areas at the superior aspect of right hepatic lobe in 7 cases (54%). This is a useful finding suggesting BCS due to inferior vena caval obstruction.

    A 67-year-old woman with asthma visited our hospital with increasing dyspnea and new-onset paresthesia and purpura in her legs. Physical examination showed a wheeze, pretibial edema, and surrounding purpura. Chest X-rays showed cardiac decompensation and an electrocardiogram revealed a new ST-T change. Laboratory data showed leukocytosis, hypereosinophilia (10,450/μL), troponin T(+), elevated BNP, and markedly elevated eosinophil cationic protein (ECP) (> 150 ng/mL). Echocardiography revealed diffuse left ventricular hypokinesis (ejection fraction 30%) with increased wall thickness. Coronary angiography was normal. Cardiac magnetic resonance imaging implied diffuse myocardial edema and subendocardial late gadolinium enhancement. Skin biopsy of purpura showed superfi cial perivascular dermatitis with remarkable eosinophilic infiltrations. No evidence of drug allergies, parasitic infection, or myeloproliferative disorder was detected. Based on these findings, a diagnosis of eosinophilic myocarditis due to Churg-Strauss syndrome was considered. She was administered prednisolone at a dose of 1 mg/kg, cyclophosphamide, and diuretics. Several markers of eosinophilic myocarditis and heart failure gradually improved, including ECP. She was discharged 30 days later with no cardiac event. Eosinophilic myocarditis is characterized by predominantly eosinophilic infi ltration. Eosinophilic granule proteins, such as ECP and major basic protein, play important roles in the pathogenesis of eosinophilic myocarditis. We experienced a rare case of eosinophilic myocarditis due to Churg-Strauss syndrome. Markedly elevated ECP played an important role in the early diagnosis and subsequent reduction in ECP served as a marker of monitoring. In an asthmatic patient with dyspnea, hypereosinophilia, and vasculitis, Churg-Strauss syndrome with eosinophilic myocarditis should be considered.

    We report a case of Angelman syndrome (AS) with paternal uniparental disomy (pUPD) of chromosome 15. This 6-year-old girl with overgrowth had frequent, but only provoked laughter, was mildly ataxic with limb hypertonia, and had no intelligible speech. She had deep-set eyes, protruding tongue, and prominent chin. The karyotype was normal. DNA analysis with microsatellites from chromosome 15 showed no inheritance of maternal alleles both within and outside the AS critical region. Proximal markers showed reduction to homozygosity of paternal alleles, intermediate markers showed nonreduction, and distal markers reduction, thus suggesting a meiosis II nondisjunction event in the father with two crossovers. This is, to our knowledge, the first reported case of AS due to meiosis II nondisjunction. We present detailed physical measurements in this patient, adding to the clinical description of the milder phenotype in AS due to pUPD.

    Dubin-Johnson syndrome is a chronic, benign, intermittent jaundice, mostly of conjugated hyperbilirubinemia. The level of bilirubin is not expected to be more than 20 mg/dl in this syndrome. In this article, we report a patient who was evaluated for hyperbilirubinemia and liver function test abnormalities and diagnosed with Dubin-Johnson syndrome coexisting with hereditary spherocytosis. We suggest that other diseases should be investigated if patients with Dubin-Johnson syndrome present with severe hyperbilirubinemia. Dubin-Johnson syndrome accompanied by hemolytic diseases might also have high coproporphyrin levels (as in Rotor's syndrome) than expected in pure Dubin-Johnson syndrome.

    Refeeding syndrome (RS) is a serious and potentially fatal disorder. It is caused by a shift of fluids, sodium, potassium, magnesium and phosphorus as well changes in the metabolism of glucose, protein, fat and vitamins following the refeeding of malnourished patients, whether enterally or parenterally. RS has rarely been reported in patients with advanced kidney disease probably due to the pre-existing hyperphosphatemia, hypermagnesemia and hyperkalemia in these patients. In the following report, we present a patient with nephronophthisis type 1 deletion syndrome in whom her main previous nutrition was limited to simply rehydration to avoid renal replacement therapy. On presentation, she was cachectic and dehydrated with advanced kidney failure. She was treated with medical nephrectomy using non-steroidal anti-inflammatory drugs and then placed on maintenance hemodialysis. Percutaneous endoscopic gastrostomy was used for her initial feeding. Care was exercised during her early refeeding with regard to correction of fluids and essential electrolytes, viz. potassium, phosphorus and magnesium, as well as multivitamins to avoid the cardiovascular and neurological complications of RS. However, the changes in the gut, pancreas and liver as well as her hyperlipidemia were a clear obstacle. Fortunately, the ileus and pancreatitis she developed on refeeding improved dramatically with a decrease of the feeding dose to half; however, the liver abnormalities and hyperlipidemia were severe and slow to recover. These improved after addition of ursodeoxycholic acid and permitted successful increase of the dose of feeding subsequently.

    Inadequate therapeutic response to parenteral corticosteroids in patients with acute bronchial asthma is infrequent. We report four patients whose bronchial asthma symptoms worsened after treatment with parenteral corticosteroids. All had larvae of Strongyloides stercoralis in the stool. The new attack or the exacerbation of asthma appeared to be precipitated by systemic corticosteroid administration. The paradoxic therapeutic response of asthma to glucocorticoides was the major pulmonary manifestation of Strongyloides superinfection; there was no evidence of other organ involvement. Individuals with new onset of bronchial asthma or worsening of asthmatic episodes concurrent with the use of systemic corticosteroids should have thorough investigation for possible superinfection due to Strongyloides stercoralis. This is particularly important for patients who have resided in areas where intestinal helminthic infections are endemic. Discontinuance of steroid therapy or reduction in dosage of parenteral steroids appears necessary. Treatment with thiabendazole appears to be effective in patients with limited hyperinfection syndrome.

    Incidence of falciparum malaria in developed countries has increased in recent years due to tourism to tropical countries and immigration from Asia and Africa. In Switzerland, about 250 cases of malaria were reported in 1994 to the Federal Office of Health, including three cases with fatal outcome.1 The most commonly described complications of plasmodia infection are cerebral malaria, acute renal failure, and severe anemia with disseminated intravascular coagulation. However, pulmonary involvement occurs in 3 to 10% of cases and represents the most serious complication of this infection, with a lethality of 70%.2,3 Furthermore, a pronounced general immunosuppression has been reported in malaria patients, which may predispose them to opportunistic infections.4 We report a case of Plasmodium falciparum infection complicated by severe acute respiratory distress syndrome (ARDS) with development of systemic cytomegalovirus (CMV) infection leading to death. This evolution implies a severe immune deficiency associated with malaria, as previously suggested in the literature.

    The effect of anxiety and depression on patients with acute coronary syndromes (ACS) warrants investigation, especially during periods of economic crisis. To investigate the relation between anxiety and depression in patients presenting with ACS due to financial crisis and to investigate whether these two entities could predict long-term cardiovascular mortality. Anxiety and depression symptoms were assessed in 350 patients (210 men) presenting with ACS, with 70 (20%) patients showing elevated scores (Hellenic Heart Failure Protocol). Over a mean follow-up of 48 months there were 36 (10%) cardiovascular deaths. Cox proportional hazards models adjusted for other prognostic factors (including age, sex, marital status, creatinine levels, left ventricular ejection fraction, heart failure, atrial fibrillation, previous hospitalisation, and baseline medications) showed that elevated anxiety and depression scores significantly predicted cardiovascular mortality (primary outcome) and all-cause mortality. Elevated anxiety and depression symptoms are related to cardiovascular mortality due probably to financial crisis, even after adjustment for other prognostic indicators in patients with ACS, who received optimised medical treatment.

    Obesity hypoventilation syndrome (OHS) is often diagnosed late. The aim of this study was to analyse gender differences at initiation of long-term mechanical ventilation (LTMV) in patients with (OHS), to analyse gender differences in treatment effect and to study how the prescription of LTMV due to OHS has changed over time. Data on patients on LTMV due to OHS between 1996 and 2014 were obtained from Swedevox, a nationwide health quality registry of patients on LTMV in Sweden. When starting LTMV, women were generally older (age 64.4 ± 11.2 vs. 60.1 ± 12.1 years, p obese (BMI 43.0 ± 8.2 vs. 41.5 ± 7.9 kg/m2, p differ. During the study period, the age of patients at the initiation of LTMV rose by 3.4 years/decade (P = 0.001) in women and with 1.9 years/decade (P = 0.048) in men but there were no significant changes in BMI (P = 0.425). Diagnosis of OHS is more delayed in women and as a consequence the disease is more advanced when diagnosed. In spite of this, there is no gender difference in survival rate in patients with OHS treated with LTMV. More and older patients with OHS nowadays gain access to LTMV. Copyright © 2015 Elsevier Ltd.

    Full Text Available Background: Snakebite is a health issue specific to some parts of the world, especially in the tropical area, where it produces many victims. The main clinical damage caused by snake bite involves hemotoxic, neurotoxic and myotoxic reactions. It is also established that the importance of systemic impairment varies according to individual factors and are related to organ dysfunction, shock or hypotension. We report the case of a young woman suffering from snakebite who developed deep vein thrombosis and compartment syndrome. Case Report: We present the case of a 32-year-old Romanian woman who was injured by her own Crotalinae snake (also known as pit viper or rattlesnake on her left forearm. When admitted to our Emergency Department, she was conscious with a Glasgow coma scale of 12/15, somnolent, febrile, suffering of headache, tachypnea; the marks of the snakebite were located in the distal part of the anterior left forearm; she had pain and bleeding at the bite site and swelling of the left upper limb with lymphangitis up to the axilla. She experienced fasciotomy-requiring compartment syndrome of the upper limb and required unfractionated heparin and closed monitored using activated partial thromboplastin time evolution due micro-thrombosis in the brachial vein. Local improvement was achieved in the next 4 days with progressive diminish of local tenderness and swelling. Conclusion: Limb deep vein thrombosis might be induced by snakebite, despite pro-hemorrhagic general condition induced by the envenomation. High index of clinical suspicion is needed for early diagnosis and timely management which can improve survival of these patients

    Waardenburg syndrome (WS) is an inherited autosomal dominant genetic disorder presenting variable penetrance and expressivity, with an estimated prevalence of 1:42,000. Clinical characteristics of WS include lateral displacement of the internal eye canthus, hyperplasia of the medial portion of the eyebrows, prominent and broad nasal base, congenital deafness, pigmentation of the iris and skin, and white forelock. A 24-year-old male patient, previously diagnosed with WS, was referred to the Special Needs Dental Clinic of Sacred Heart University, Bauru, Brazil. Parents reported that the patient was experiencing self-mutilation, particularly in the oral region. He presented multiple congenital anomalies, including anophthalmia, mental retardation, low-set ears, and leg deformities. Clinical oral examination revealed hypodontia, abnormalities in dental morphology, extensive dental caries, periodontal disease, and fistulae. Extensive scars on the tongue, lips, and hands caused by self-mutilation were also observed. In accordance with his family and neurologist, full-mouth extraction under general anesthesia was performed, especially considering his severe self-aggressive behavior and the necessity to be fed with soft-food diet due to his inability to chew. After the surgical procedure, a significant reduction in the patient's irritability and gain of weight were reported in the follow-ups of 30, 60, and 180 days.

    Professional burnout is defined as a state of depletion and loss of motivation accompanied by different mental and physical symptoms. To assess personal losses suffered by correctional officers due to burnout. This cross-sectional study conducted between June and December 2012 included 201 correctional officers in two Bulgarian prisons. The mean age of the whole group was 41.2 (SD 8.0) years. The respondents was mostly male (56.7%), married (72.6%), had a secondary educational level (61.7%), and 76.1% of them had been in current prison work over 5 years. The demographic characteristics had no influence on the occurrence of burnout but there was a correlation between level of burnout and the number of sick-leaves, the need for medical help, and the expenses spent on medications. Officers affected by burnout took more sick-leaves and this affected adversely their remuneration as they lost 3.1% of their annual wages. Their expenses spent on user fees for medical services were 3 times higher. Their monthly expenses spent on medications were 3.14 times higher than those of people without the burnout syndrome. The high level of burnout has a negative personal economic effect on the prison employees.

    Full Text Available Syncope is a sudden and brief loss of consciousness with postural tone. Its recovery is usually spontaneous. There are various causes of syncope including cardiac, vascular, neurologic, metabolic and miscellaneous origins. The tracing is usually time-consuming and costly. The diagnosis of carotid sinus syncope may sometimes be difficult since the symptoms are nonspecific, especially in older persons. Here, we report the case of a 72-year-old woman who sought medical attention at our hospital due to repeated syncope episodes over the previous 5 years. Neurologic examinations showed negative results (including brain computed tomography. Twenty-four-hour ambulatory electrocardiogram monitoring showed atrial and ventricular premature contractions only. Electrophysiologic study disclosed prolonged corrected sinus node recovery time (1,737 ms with poor atrioventricular conduction. Drop of blood pressure together with sinus bradycardia developed after left side carotid sinus massage. Both carotid sinus hypersensitivity with sick sinus syndrome contributed to this patient's syncope, and after pacemaker placement together with selective serotonin reuptake inhibitor treatment, she was free from syncope thereafter.

    A 20-year-old woman was referred for evaluation after about 2 years of recurrent episodes of localized urticaria during handling of several kinds of raw fish in a sushi shop, where she had worked part-time for 2 years. She had also experienced allergic symptoms such as itching and swelling of her lips, generalized urticaria, laryngeal tightness, stridor and dyspnea immediately after ingestion of raw and cooked seafood, including sole, horse mackerel, sea eel and shellfish, over the previous 1 year before referral. Skin prick tests and blood test for specific IgE antibodies were positive for many kinds of seafood, including sole, horse mackerel, sea eel, eel, crab, and abalone, which belonged to different taxonomic phyla, including Chordata, Arthropoda, and Mollusca. A challenge with a piece of broiled sole induced swelling of the lips, obstruction of the larynx, difficulty with deglutition, and abdominal pain. In addition, serum-specific IgE antibodies to two major fish allergens, parvalbumin and collagen, were detected by ELISA, suggesting that allergic symptoms could be induced by many kinds of seafood in the present patient. She was therefore diagnosed with occupational contact urticaria and oral allergy syndrome due to seafood. At the time of this report, the present patient had been followed for one year and no reactions have occurred since she started to avoid the causative types of seafood.

    B+NK+SCID (severe combined immunodeficiency) due to IL7Rα deficiency represents approximately 10% of American SCID cases. To better understand the spectrum of autoimmune disorders associated with IL7Rα deficiency, we describe two unrelated IL7Rα-deficient female SCID infants whose clinical picture was dominated by autoimmune manifestations: one with intrauterine Omenn syndrome (OS) and another with persistent thrombocytopenic purpura since 4months of age. The OS baby harbored a homozygous p.C118Y mutation in IL7R. She presented dense eosinophilic infiltrates in several organs, including pancarditis, which may have contributed to her death (on the 2nd day of life). B cells were observed in lymph nodes, spleen, bone marrow and thymus. The second patient harbored compound heterozygous p.C118Y and p.I121NfsX8 mutations. She underwent a successful unrelated cord blood transplant. In conclusion, early OS can be observed in patients with IL7R mutations, and autoimmune cytopenias could also complicate the clinical course of SCID babies with this type of defect. Copyright © 2014.

    Thyroid gland disorders are variably associated with Prader-Willi syndrome (PWS). Many of the clinical features in newborns with PWS are similar to those found in congenital hypothyroidism (CH). We report a case of a girl with CH and PWS. At the age of 9 months CH caused by an ectopic sublingual thyroid was diagnosed, and hormone replacement therapy was started. In spite of this treatment a decrease in growth velocity, weight excess and delayed development were observed. At the age of 9 years PWS was suspected on the basis of phenotype and genetic tests confirmed a maternal uniparental disomy of chromosome 15. This is the second reported case of hypothyroidism due to an ectopic sublingual thyroid gland in PWS suggesting that, although rare, an association between CH and PWS may exist. In our case diagnosis of PWS was delayed because mental retardation, hypotonia, obesity and short stature were initially attributed to hypothyroidism. In this context PWS should be considered in obese children with CH who do not improve adequately with l-thyroxine therapy. Also, thyroid function in all PWS children should be assessed regularly in order to avoid delayed diagnosis of hypothyroidism.

    Full Text Available ABSTRACT Sweet sorghum [Sorghum bicolor (L. Moench] stands out as a complementary crop to sugarcane Saccharum spp. for the production of ethanol, since it has juicy stems with directly fermentable sugars. Due to this fact, there is a need for the analysis of sweet sorghum properties in order to meet the agro-industry demand. This work aimed to develop and study the maturation curves of seven sweet sorghum cultivars in ten harvest dates. The results showed a significant difference between cultivars and harvest dates for all parameters analysed (p≤0.01. Regarding the sugar content, the cultivars BRS508, XBWS80147 and CMSX629 showed the highest means for the total reducing sugars (TRS and recoverable sugar (RS. In the production of ethanol per tonne of biomass (EP, the cultivars BRS508 and CMSX629 presented the best results.

  8. Drug versus sweet reward: greater attraction to and preference for sweet versus drug cues.

    Madsen, Heather B; Ahmed, Serge H

    2015-05-01

    Despite the unique ability of addictive drugs to directly activate brain reward circuits, recent evidence suggests that drugs induce reinforcing and incentive effects that are comparable to, or even lower than some nondrug rewards. In particular, when rats have a choice between pressing a lever associated with intravenous cocaine or heroin delivery and another lever associated with sweet water delivery, most respond on the latter. This outcome suggests that sweet water is more reinforcing and attractive than either drug. However, this outcome may also be due to the differential ability of sweet versus drug levers to elicit Pavlovian feeding-like conditioned responses that can cause involuntary lever pressing, such as pawing and biting the lever. To test this hypothesis, rats first underwent Pavlovian conditioning to associate one lever with sweet water (0.2% saccharin) and a different lever with intravenous cocaine (0.25 mg) or heroin (0.01 mg). Choice between these two levers was then assessed under two operant choice procedures: one that permitted the expression of Pavlovian-conditioned lever press responses during choice, the other not. During conditioning, Pavlovian-conditioned lever press responses were considerably higher on the sweet lever than on either drug lever, and slightly greater on the heroin lever than on the cocaine lever. Importantly, though these differences in Pavlovian-conditioned behavior predicted subsequent preference for sweet water during choice, they were not required for its expression. Overall, this study confirms that rats prefer the sweet lever because sweet water is more reinforcing and attractive than cocaine or heroin. © 2014 Society for the Study of Addiction.

  9. Australian print news media coverage of sweet, non-alcoholic drinks sends mixed health messages.

    This study aimed to analyse the contribution of Australian print news coverage to the public profile of sweet, non-alcoholic beverages. News media portrayal of health contributes to individuals' decision-making. The focus on sugar-sweetened beverages reflects their contribution to excessive energy intake. One year's coverage of sweet, non-alcoholic beverages by major Australian newspapers was analysed using content and frame analysis. Research questions addressed which sweet drinks are most prominently covered, what makes sweet drinks newsworthy and how are the health aspects of sweet drinks framed? Fruit juice was the most widely covered sweet drink, closely followed by carbonated, sugar-sweetened soft drinks. Overall coverage was positively oriented towards sweet drinks, with fruit juice primarily portrayed as having health benefits. Some coverage mentioned risks of sweet drinks, such as obesity, tooth decay, metabolic syndrome and heart attack. Sweet drinks often enjoy positive coverage, with their health benefits and harms central to their ability to attract journalists' attention. However, the mix of coverage may be contributing to consumer confusion about whether it is safe and/or healthy to consume sweet non-alcoholic drinks. Framing of sweet drinks as healthy may undermine efforts to encourage individuals to avoid excess consumption of energy-dense drinks which offer few or minimal health benefits. © 2011 The Authors.

    Sucrose can be substituted by intense sweeteners to lower the calorie content of soft drinks. Although the sweetness is kept at the same level as much as possible, the flavour of the product often changes. This change could be due to both the mechanism of sensory perception and interactive effects

    Sweet taste is a powerful factor influencing food acceptance. There is considerable variation in sweet taste perception and preferences within and among species. Although learning and homeostatic mechanisms contribute to this variation in sweet taste, much of it is genetically determined. Recent studies have shown that variation in the T1R genes contributes to within- and between-species differences in sweet taste. In addition, our ongoing studies using the mouse model demonstrate that a sign...

    Age affects the human taste system at peripheral and central levels. Metabolic syndrome is a constellation of risk factors (e.g., abdominal obesity and hypertension) that co-occur, increase with age, and heighten risk for cardiovascular disease, diabetes, and cognitive decline. Little is known about how age, metabolic syndrome, and hunger state interact to influence how the brain processes information about taste. We investigated brain activation during the hedonic evaluation of a pleasant, nutritive stimulus (sucrose) within regions critical for taste, homeostatic energy regulation, and reward, as a function of the interactions among age, metabolic syndrome, and hunger condition. We scanned young and elderly adults, half with risk factors associated with metabolic syndrome twice: Once fasted overnight and once after a preload. Functional magnetic resonance imaging data indicated significant effects of age as well as interactive effects with metabolic syndrome and hunger condition. Age-related differences in activation were dependent on the hunger state in regions critical for homoeostatic energy regulation and basic as well as higher order sensory processing and integration. The effects of age and metabolic syndrome on activation in the insula, orbital frontal cortex, caudate, and the hypothalamus may have particularly important implications for taste processing, energy regulation, and dietary choices.

    Short stature represents one of the main features of children with Noonan syndrome. The reason for impaired growth remains largely unknown. To assess GH and IGF1 secretion in children with Noonan syndrome. 12 prepubertal children with Noonan syndrome due to mutations in the PTPN11 gene [7 males, 6 females; median age, years: 8.6 (range 5.1-13.4)] were studied; 12 prepubertal children with short stature (SS) [7 males, 5 females; median age, years: 8.1 (range 4.8-13.1)] served as the control group. GH secretion after arginine stimulation test; IGF1 generation test by measurement of IGF1 levels before and after recombinant GH (rGH) administration (0.05 mg/kg/day for 4 days). Baseline and stimulated peak values of GH were not significantly different between the two groups. At +120 minutes, GH levels remained significantly higher (p = 0.0121) in comparison with baseline values in children with Noonan syndrome. Baseline IGFI levels in patients and in SS controls were not significantly different, in contrast to values after the rGH generation test [205 ng/mL (interquartiles 138.2-252.5 ng/mL) and 284.5 ng/mL (interquartiles 172-476 ng/mL), respectively; p = 0.0248]. IGF1 values were significantly related to height (baseline: r = 773, p = 0.0320; peak: r = 0.591, p = 0.0428) in children with Noonan syndrome. Blunted increase of IGF1 after the rGH generation test was present in children with Noonan syndrome due to mutations in the PTPN11 gene in comparison with SS children. This finding may be due to partial GH resistance in the former likely related to altered Ras-MAPK signaling pathway.

    Full Text Available We present a case of a patient with Anton’s syndrome (i.e., visual anosognosia with confabulations, who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton’s syndrome, he might have had Charles Bonnet syndrome, characterized by both visual loss and hallucinations. Anton syndrome, is not so frequent condition and is most commonly caused by ischemic stroke. In this particular case, the patient had successive bilateral occipital ischemia as a result of massive stenoses of head and neck arteries.

    Acute fever of unknown origin (AFUO) is established when the anamnesis and physical examination cannot identify the cause. In infants less than 3 months-old this is situation for concern, due to the risk of a serious bacterial infection. To describe the clinical and laboratory variable of patients with AFUO, in order to look for clues in order to base studies on the decisions arising drom this problem. A report is presented on a retrospective study conducted on a cohort of children less than three months-old admitted to the Hospital Roberto del Río (2007-2011) due to an AFUO. Clinical histories were reviewed and the patients were grouped, according to the severity of the admission diagnosis, into severe and non-severe. They were compared in strata determined by the variables of clinical interest. A total of 550 children were admitted with AFUO during the study period. There was low agreement between the severity on admission and at discharge (kappa=0.079; P=.26). There were 23.8% of children in the severe group and 76.2% in the non-severe group. Urinary tract infection predominated in the severe group (68.7%) and 40.7% with acute febrile syndrome in the non-severe group. The cut-off levels for C-reactive protein, white cells, and neutrophils per mm(3), to calculate the fixed and variable indices, only showed negative predictive values of some use for ruling out serious bacterial infection. The ROC curves with white cell and neutrophil counts and C-reactive protein, did not provide andy fixed indices of clinical use. More than one-third (34.6%) of lumbar punctures were traumatic or failures. According to the results of this study, there is an obvious excess of hospital admissions, little usefulness in the examinations to identify serious bacterial infection, a high percentage lumbar punctures traumatic and lumbar punctures failures, and an excess of antibiotic treatments. A review of clinical criteria and procedures is needed. Copyright © 2015 Sociedad Chilena de

    Insulin resistance syndromes without lipodystrophy are an infrequent and heterogeneous group of disorders with variable clinical phenotypes, associated with hyperglycemia and hyperinsulinemia. The three conditions related to mutations in the insulin receptor gene are leprechaunism or Donohue syndrome, Rabson-Mendenhall syndrome, and Type A syndrome. A case is presented on a patient diagnosed with type A insulin resistance, defined by the triad of extreme insulin resistance, acanthosis nigricans, and hyperandrogenism, carrying a heterozygous mutation in exon 19 of the insulin receptor gene coding for its tyrosine kinase domain that is crucial for the catalytic activity of the receptor. The molecular basis of the syndrome is reviewed, focusing on the structure-function relationships of the insulin receptor, knowing that the criteria for survival are linked to residual insulin receptor function. It is also pointed out that, although type A insulin resistance appears to represent a somewhat less severe condition, these patients have a high morbidity and their treatment is still unsatisfactory.

    2012-07-01

    Although frontal dysexecutive disorders are frequently considered to be due to working memory deficit, this has not been systematically examined and very little evidence is available for impairment of working memory in frontal damage. The objective of this study was to examine the components of working memory, their anatomy and the relations with executive functions in patients with stroke involving the frontal or posterior cortex. The study population consisted of 29 patients (frontal: n=17; posterior: n=12) and 29 matched controls. Phonological loop (letter and word spans, phonological store; rehearsal process), visuospatial sketchpad (visuospatial span) and the central executive (working memory span, dual task and updating process) were examined. The group comparison analysis showed impairment in the frontal group of: (i) verbal spans (Pdeficit of the rehearsal process (P=0.006); (iii) visuospatial span (P=0.04); (iv) working memory span (P=0.001) that disappeared after controlling for verbal span and (v) running memory (P=0.05) unrelated to updating conditions. The clinical anatomical correlation study showed that impairment of the central executive depended on frontal and posterior lesion. Cognitive dysexecutive disorders were observed in 11/20 patients with central executive deficit and an inverse dissociation was observed in two patients. Receiver operating characteristic curve analysis indicated that cognitive dysexecutive disorders had the highest ability to discriminate frontal lesions (area under curve=0.844, 95% confidence interval: 0.74-0.95; P=0.0001; central executive impairment: area under curve=0.732, 95% confidence interval: 0.57-0.82; P=0.006). This study reveals that frontal lesions induce mild impairment of short-term memory associated with a deficit of the rehearsal process supporting the role of the frontal lobe in this process; the central executive depends on lesions in the frontal lobe and posterior regions accounting for its low frequency

    Full Text Available Background: Autoimmune hypothyroidism (Hashimoto thyroiditis; HT is the most common postnatal thyroid disease. Clinical manifestations of HT vary according to disease severity. Due to the pleiotropic effects of thyroid hormone, less common signs and symptoms of HT can occur, leading to a delay in diagnosis. Case presentation: A 9-year-old girl of Indian origin was admitted for a one-week history of widespread myalgia, fatigue, muscle weakness, difficulty walking, and a significant increase in weight (approximately 2 kg without any changes in daily habits. The only relevant medical history was several intermittent vaginal bleeding episodes since four years of age. Breast development was consistent with Tanner stage 2 without pubic or axillary hair; while height and weight were at the 10th percentile and the 38th percentile; respectively. Bone age from a left wrist X-ray was delayed 1 year. Pelvic ultrasonography revealed a uterine body/neck ratio of >1 (pubertal stage and multifollicular ovaries. Her external genitalia had a childlike appearance. Laboratory examinations showed an increased thyroid-stimulating hormone, decreased free thyroxine, and positive anti-thyroglobulin antibody titres, as well as elevation of creatine phosphokinase, myoglobin, lactate dehydrogenase, serum aspartate aminotransferase, hypercholesterolemia, and a basal serum prolactin near the upper limit of normal. Follicle stimulating hormone and estradiol were slightly and significantly elevated, respectively. Thyroid ultrasound showed an increased gland size with irregular echostructures and high vascularization. Levothyroxine replacement therapy led to complete normalization of clinical and laboratory findings, including rhabdomyolysis indices. No further vaginal bleeding episodes were reported. Conclusion: This case report highlights how various can be the clinical picture of HT in children, and how rare clinical manifestations can be the only signs of disease at

    2017-01-01

    Abstract Rationale: Saccharated ferric oxide has been shown to lead to elevation of fibroblast growth factor 23, hypophosphatemia, and, consequently, osteomalacia. Moreover, mineral imbalance is often observed in patients with short-bowel syndrome to some degree. Patient concerns: A 62-year-old woman with short-bowel syndrome related with multiple resections of small intestines due to Crohn disease received regular intravenous administration of saccharated ferric oxide. Over the course of treatment, she was diagnosed with tetany, which was attributed to hypocalcemia. Additional assessments of the patient revealed not only hypocalcemia, but also hypophosphatemia, hypomagnesemia, osteomalacia, and a high concentration of fibroblast growth factor 23 (314 pg/mL). Diagnoses: We diagnosed her with mineral imbalance-induced osteomalacia due to saccharated ferric oxide and short-bowel syndrome. Interventions: Magnesium replacement therapy and discontinuation of saccharated ferric oxide alone. Outcomes: These treatments were able to normalize her serum mineral levels and increase her bone mineral density. Lessons: This case suggests that adequate evaluation of serum minerals, including phosphate and magnesium, during saccharated ferric oxide administration may be necessary, especially in patients with short-bowel syndrome.

    Whole-exome sequencing was used to identify the disease gene(s) in a Spanish girl with failure to thrive, muscle weakness, mild facial weakness, elevated creatine kinase, deficiency of mitochondrial complex III and depletion of mtDNA. With whole-exome sequencing data, it was possible to get the whole mtDNA sequencing and discard any pathogenic variant in this genome. The analysis of whole exome uncovered a homozygous pathogenic mutation in thymidine kinase 2 gene ( TK2; NM_004614.4:c.323 C>T, p.T108M). TK2 mutations have been identified mainly in patients with the myopathic form of mtDNA depletion syndromes. This patient presents an atypical TK2-related myopathic form of mtDNA depletion syndromes, because despite having a very low content of mtDNA (TK2 gene in mtDNA depletion syndromes and expanded the phenotypic spectrum.

    Full Text Available Neuropsychiatric symptoms in Alzheimer’s disease (AD are prevalent, however their relationship with patterns of cortical atrophy is not fully known. Objectives To compare cortical atrophy’s patterns between AD patients and healthy controls; to verify correlations between neuropsychiatric syndromes and cortical atrophy. Method 33 AD patients were examined by Neuropsychiatric Inventory (NPI. Patients and 29 controls underwent a 3T MRI scanning. We considered four NPI syndromes: affective, apathy, hyperactivity and psychosis. Correlations between structural imaging and neuropsychiatric scores were performed by Freesurfer. Results were significant with a p-value < 0.05, corrected for multiple comparisons. Results Patients exhibited atrophy in entorhinal cortices, left inferior and middle temporal gyri, and precuneus bilaterally. There was correlation between affective syndrome and cortical thickness in right frontal structures, insula and temporal pole. Conclusion Cortical thickness measures revealed atrophy in mild AD. Depression and anxiety symptoms were associated with atrophy of right frontal, temporal and insular cortices.

    Background and Aims Although the clinical phenotype of Lynch syndrome (also known as Hereditary Nonpolyposis Colorectal Cancer) has been well described, little is known about disease in PMS2 mutation carriers. Now that mutation detection methods can discern mutations in PMS2 from mutations in its pseudogenes, more mutation carriers have been identified. Information about the clinical significance of PMS2 mutations is crucial for appropriate counseling. Here, we report the clinical characteristics of a large series of PMS2 mutation carriers. Methods We performed PMS2 mutation analysis using long range PCR and MLPA for 99 probands diagnosed with Lynch syndrome-associated tumors showing isolated loss of PMS2 by immunohistochemistry. Penetrance was calculated using a modified segregation analysis adjusting for ascertainment. Results Germline PMS2 mutations were detected in 62% of probands (n = 55 monoallelic; 6 biallelic). Among families with monoallelic PMS2 mutations, 65.5% met revised Bethesda guidelines. Compared with the general population, in mutation carriers, the incidence of colorectal cancer was 5.2 fold higher and the incidence of endometrial cancer was 7.5 fold higher. In North America, this translates to a cumulative cancer risk to age 70 of 15–20% for colorectal cancer, 15% for endometrial cancer, and 25–32% for any Lynch syndrome-associated cancer. No elevated risk for non-Lynch syndrome-associated cancers was observed. Conclusions PMS2 mutations contribute significantly to Lynch syndrome but the penetrance for monoallelic mutation carriers appears to be lower than that for the other mismatch repair genes. Modified counseling and cancer surveillance guidelines for PMS2 mutation carriers are proposed. PMID:18602922

    Papillon-Lefevre syndrome (PLS) is an autosomal recessive disease that is characterized by symmetric palmoplantar keratodermatitis and severe periodontal destruction. Mutations in the cathepsin C gene (CTSC) have recently been detected in PLS. Immune dysregulation, due to a mutation in CTSC, increases the risk of pyogenic infections in PLS patients. A child with PLS is presented here with liver abscesses and peritonitis caused by Rhizopus oryzae. His liver abscess and peritonitis were cured with amphotericin B without surgical care. This is the first case in the literature liver abscess due to Rhizopus oryzae in a child with PLS.

    Usher syndrome (USH) is an autosomal recessive condition characterized by sensorineural hearing loss, vestibular dysfunction, and visual impairment due to retinitis pigmentosa. Truncating mutations in the cadherin-23 gene (CDH23) result in Usher syndrome type 1D (USH1D), whereas missense mutations affecting strongly conserved motifs of the CDH23 protein cause non-syndromic deafness (DFNB12). Four missense mutations constitute an exception from this genotype-phenotype correlation: they have been described in USH1 patients in homozygous state. Using a minigene assay, we have investigated these changes (c.1450G>C, p.A484P; c.3625A>G, p.T1209A; c.4520G>A, p.R1507Q; and c.5237G>A, p.R1746Q) for a possible impact on mRNA splicing which could explain the syndromic phenotype. While in silico analysis suggested impairment of splicing in all four cases, we found aberrant splicing for only one mutation, p.R1746Q. However, splicing was normal in case of p.A484P, p.T1209A and p.R1507Q. These three latter CDH23 missense mutations could interfere with functions of both, the auditory and the visual system. Alternatively, they could represent rare non-pathogenic polymorphisms.

    The calcium sensing receptor (CaSR) plays an important role in calcium homeostasis. Activating mutations of CaSR cause autosomal dominant hypocalcemia by affecting parathyroid hormone secretion in parathyroid gland and calcium resorption in kidney. They can also cause a type 5 Bartter syndrome by inhibiting the apical potassium channel in the thick ascending limb of the loop of Henle in the kidney. This study presents a patient who had autosomal dominant hypocalcemia with Bartter syndrome due to an activating mutation Y829C in the transmembrane domain of the CaSR. Symptoms of hypocalcemia occurred 12 days after birth and medication was started immediately. Medullary nephrocalcinosis and basal ganglia calcification were found at 7 years old and at 17 years old. Three hypercalcemic episodes occurred, one at 14 years old and two at 17 years old. The Bartter syndrome was not severe while the serum calcium concentration was controlled, but during hypercalcemic periods, the symptoms of Bartter syndrome were aggravated.

    Nance-Horan Syndrome (NHS) is a rare X-linked syndrome characterized by congenital cataract which leads to profound vision loss, characteristic dysmorphic features and specific dental anomalies. Microcornea, microphthalmia and mild or moderate mental retardation may accompany these features. Heterozygous females often manifest similarly but with less severe features than affected males. We describe two brothers who have the NHS phenotype and their carrier mother who had microcornea but not cataract. We identified a previously unreported frameshift mutation (c.558insA) in exon 1 of the NHS gene in these patients and their mother which is predicted to result in the incorporation of 11 aberrant amino acids prior to a stop codon (p.E186Efs11X). We also discussed genotype-phenotype correlation according to relevant literature. Copyright © 2013 Elsevier B.V. All rights reserved.

    The conditions Juvenile Polyposis Syndrome (JPS) and Hereditary Mixed Polyposis Syndrome (HMPS) are associated with an increased risk of colorectal carcinoma. The genetic mechanisms which explain these conditions have until recently been poorly understood. Recent interest has focused on the transforming growth factor (TGF)-beta signalling pathway and, in particular, on mutations in the SMAD4 gene. However, not all cases of JPS and HMPS have mutations in SMAD4 and focus has now shifted to other components of the TGF-beta pathway to clarify the genetic mechanisms involved in these conditions. In this report, we describe the significance of a bone morphogenetic protein receptor type 1A gene mutation in an Irish family.

    Recent data demonstrate that dry eye (DE) susceptibility and other chronic pain syndromes (CPS) such as chronic widespread pain, irritable bowel syndrome and pelvic pain, may share common heritable factors. Previously, we showed that DE patients describing more severe symptoms tended to report features of neuropathic ocular pain (NOP). We hypothesize that patients with a greater number of CPS would have a different DE phenotype compared to those with fewer CPS. We recruited a cohort of 154 DE patients from the Miami Veterans Affairs Hospital and defined high and low CPS groups by cluster analysis. In addition to worse non-ocular pain complaints and higher PTSD and depression scores (Ppain assessed via 3 different pain scales (Ppain disorder, and that shared mechanistic factors may underlie vulnerability to some forms of DE and other comorbid CPS.

    Full Text Available Cauda equina syndrome (CES is a rare neurologic condition that is caused by compression of the cauda equina. Cauda equina consists of spinal nerves L2-L5, S1-S5 and the coccygeal nerve. The compression of these nerve roots can be caused mainly by lumbar disc herniation (45% of all causes. The diagnosis consists of two critical points: a detailed history and physical examination and b MRI or CT. The gold standard of the treatment of this syndrome is the surgical approach in combination with the timing of onset of symptoms. The surgery as an emergency situation is recommended in the fi rst 48 hours of onset of symptoms. Any delay in diagnosis and treatment leads to a poor prognosis of CES.

    Melnick Needles syndrome (MNS), Treacher Collins syndrome (TCS) and Pierre Robin syndrome (PRS) are congenital abnormalities with characteristic facial appearances that include micrognathia. A 20-year-old girl with MNS, a 16-year-old boy with TCS and a 12-year-old girl with PRS attended the sleep apnoea clinic at our institution at different times. Diagnostic sleep studies were initially performed on all three patients to confirm the diagnosis of obstructive sleep apnoea syndrome (OSAS). They subsequently commenced nasal CPAP (nCPAP) treatment and their progress was followed. A limited sleep study on the patient with MNS demonstrated moderate\\/severe OSAS with an AHI of 33 events\\/h. Commencement of nCPAP resulted in symptomatic improvement. Overnight oximetry in the patient with TCS showed repeated desaturation to SpO2<90%. Subsequent treatment by nCPAP almost completely abolished the desaturation events. Overnight polysomnography in the patient with PRS demonstrated severe OSAS with an AHI of 49 events\\/h. After 3 years of nCPAP therapy, this patient requested discontinuation of treatment. Subsequent polysomnography without nCPAP revealed an AHI of <5 events\\/h. The use of nCPAP in the patients with MNS and TCS resulted in effective control of their sleep abnormalities. Mandibular growth and enlargement of the posterior airway space led to resolution of OSAS in the patient with PRS. There is a definite role for nCPAP therapy in patients with congenital micrognathia and OSAS. The use of nCPAP may obviate the need for more invasive corrective surgery for OSAS and is not necessarily a life-long requirement.

    Venkatraman Thulasi BA

    2017-08-01

    Full Text Available Brown-Vialetto-Van Laere syndrome is a rare disorder characterized by motor, sensory, and cranial neuronopathies, associated with mutations in SLC52A2 and SLC52A3 genes that code for human riboflavin transporters RFVT2 and RFVT3, respectively. The authors describe the clinical course of a 6-year-old girl with Brown-Vialetto-Van Laere syndrome and a novel homozygous mutation c.1156T>C in the SLC52A3 gene, who presented at the age of 2.5 years with progressive brain stem dysfunction including ptosis, facial weakness, hearing loss, dysphagia, anarthria with bilateral vocal cord paralysis, and ataxic gait. She subsequently developed respiratory failure requiring tracheostomy and worsening dysphagia necessitating a gastrostomy. Following riboflavin supplementation, resolution of facial diplegia and ataxia, improvements in ptosis, and bulbar function including vocalization and respiration were noted. However, her sensorineural hearing loss remained unchanged. Similar to other cases of Brown-Vialetto-Van Laere syndrome, our patient responded favorably to early riboflavin supplementation with significant but not complete neurologic recovery.

    We report a case of flexion contractures in a patient's legs secondary to postpartum hypopituitarism. A 56-year-old woman presented with a 3-year history of worsening flexion contractures of the hips and knees. On admission, her hips and knees could not be extended, and she had muscle stiffness and tenderness to palpation of the lower extremities. We first suspected stiff-person syndrome or Isaacs' syndrome because of her muscle stiffness. However, multiple hormones did not respond to stimulation tests, and an MRI of the brain showed atrophy of the pituitary gland with an empty sella. A subsequent interview revealed that she had suffered a severe hemorrhage while delivering her third child. She was diagnosed with panhypopituitarism and started on cortisol replacement therapy. After 1 week of treatment with hydrocortisone (10 mg/day), her symptoms quickly improved. We then added 75 μg/day of thyroid hormone. During the course of her treatment, autoantibodies against VGKC complex were found to be weakly positive. However, we considered the antibodies to be unrelated to her disease, because her symptoms improved markedly with low-dose steroid treatment. There are a few reports describing flexion contractures of the legs in patients with primary and secondary adrenal insufficiency. As these symptoms are similar to those seen in stiff-person syndrome, adrenal and pituitary insufficiency should be taken into account to achieve the correct diagnosis and treatment in patients with flexion contractures and muscle stiffness.

    Posterior reversible encephalopathy syndrome (PRES) is associated with several symptoms; of those, visual acuity loss, light oversensitivity (photophobia), and light flashes (photopsia) are known as PRES-related eye symptoms. We report a post-partum woman with PRES associated with hemolysis, elevated liver enzymes, and low platelets syndrome (HELLP), in whom color vision abnormality (achromatopsia) was the sole manifestation. Cesarean section was performed at 28 weeks due to headache, epigastralgia, and severe hypertension. HELLP became evident after delivery. On post-partum day 1, she complained of achromatopsia, stating: "all things look brownish-gray". Ophthalmologic examination was normal, but brain magnetic resonance imaging showed occipital lobe lesions, indicative of PRES, and, interestingly, also color vision center (area V4) lesions, suggesting that the achromatopsia had been caused by brain damage. It may be prudent to question HELLP patients concerning achromatopsia. © 2017 Japan Society of Obstetrics and Gynecology.

    Most patients with chronic back pain suffer from degenerative thoracolumbovertebral disease. However, the following case illustrates that a localized peripheral nerve entrapment must be considered in the differential diagnosis of chronic back pain. We report the case of a 26-year-old woman with continuous excruciating pain in the lower back area. Previous treatment for nephroptosis was to no avail. On physical examination the pain was present in a 2 x 2 cm area overlying the twelfth rib some 4 cm lateral to the spinal process. Somatosensory testing using swab and alcohol gauze demonstrated the presence of skin hypo- and dysesthesia over the painful area. Local pressure on this painful spot elicited an extreme pain response that did not irradiate towards the periphery. These findings were highly suggestive of a posterior version of the anterior cutaneous nerve entrapment syndrome (ACNES), a condition leading to a severe localized neuropathic pain in anterior portions of the abdominal wall. She demonstrated a beneficial albeit temporary response after lidocaine infiltration as dictated by an established diagnostic and treatment protocol for ACNES. She subsequently underwent a local neurectomy of the involved superficial branch of the intercostal nerve. This limited operation had a favorable outcome resulting in a pain-free return to normal activities up to this very day (follow-up of 24 months).We propose to name this novel syndrome "posterior cutaneous nerve entrapment syndrome" (POCNES). Each patient with chronic localized back pain should undergo simple somatosensory testing to detect the presence of overlying skin hypo- and dysesthesia possibly reflecting an entrapped posterior cutaneous nerve.Key words: Chronic pain, back pain, posterior cutaneous nerve entrapment, peripheral nerve entrapment, surgical treatment for pain, anterior cutaneous nerve entrapment.

    Fracture of the first rib with ensuing callus formation is a rare cause of thoracic outlet syndrome. We report a case of a 17-year-old female volleyball player who presented with months of chronic arm pain. Radiographic imaging demonstrated nonunion fracture of the first rib. Physical therapy had been unsuccessful in relieving the pain, and surgical management was performed with resection of the first rib through a transaxillary approach with complete resolution of symptoms. Inflammation surrounding such fractures may destroy tissue planes, making dissection more technically difficult.

    2018-07-01

    DNA repair pathways are essential for cellular survival as our DNA is constantly under assault from both exogenous and endogenous DNA damaging agents. Five major mammalian DNA repair pathways exist within a cell to maintain genomic integrity. Of these, the DNA mismatch repair (MMR) pathway is highly conserved among species and is well documented in bacteria. In humans, the importance of MMR is underscored by the discovery that a single mutation in any 1 of 4 genes within the MMR pathway (MLH1, MSH2, MSH6 and PMS2) results in Lynch syndrome (LS). LS is a autosomal dominant condition that predisposes individuals to a higher incidence of many malignancies including colorectal, endometrial, ovarian, and gastric cancers. In this review, we discuss the role of PMS2 in the MMR pathway, the evolving testing criteria used to identify variants in the PMS2 gene, the LS phenotype as well as the autosomal recessive condition called constitutional mismatch repair deficiency syndrome, and current methods used to elucidate the clinical impact of PMS2 mutations. © 2017 John Wiley & Sons A/S.

    Burning mouth syndrome (BMS) is a relatively common disease that can severely affect the quality of life of the patient. It causes chronic orofacial pain or oral burning sensation even in the absence of any detectable organic cause. The etiology of BMS is complex and multifactorial. It has been associated with menopause, trigger events and even genetic polymorphisms. Although its etiology remains unclear, there is still much evidence that psychological elements like stress, anxiety or depression do play a significant role. There are several studies in the literature which only report the association of BMS with psychological factors. But to the best of our knowledge, there is no such case reported in the literature which has actually highlighted the management of such a case with psychogenic elements involved. In this case report, apart from discussing the role of psychological factors, the treatment of BMS with emphasis on counseling is also emphasized. Further, it is of interest to know that such patients with psychologically induced burning mouth syndrome have to be evaluated to their deepest details. Even their commonly overlooked gestures and habits like watching a particular television soap opera may be involved in their disease process. It can be concluded that psychological counseling in general dental practice can provide an effective cure for chronic oral burning sensation with psychological factors involved. PMID:25093058

    Full Text Available In pregnancy, advanced vertebral hemangiomas may be seen, and these require treatment. The case reported here is of a 35-year-old female in the 32nd week of pregnancy who was admitted to the orthopaedics clinic with a history of backache and difficulty walking. A burst fracture of L1 associated with a vertebral hemangioma was identified with an L3 compression fracture secondary to osteoporosis. The local kyphosis angle between T12 and L2 was 27°. Kyphotic deformity was corrected and postoperatively, the measured T12–L2 local kyphotic angle was 9°. Twelve hours postoperatively, oral nutrition was allowed, but she developed nausea and vomiting and twenty-four hours postoperatively, an electrolyte imbalance developed. Postoperatively, the patient was diagnosed with superior mesenteric artery syndrome. To the best of our knowledge, this is the first reported case of superior mesenteric artery syndrome, which occurred following the correction of a kyphotic deformity that had developed secondary to an advanced hemangioma in pregnancy.

    Pheochromocytomas in pregnancy are rare but potentially lethal. Even rarer is the combination of pheochromocytoma in pregnancy with subsequent development of ectopic Cushing's syndrome. We report a 36-year-old woman, previously diagnosed with essential hypertension, who developed severe hypertension in pregnancy complicated by insulin-dependent gestational diabetes. A cesarean section was performed at 32 weeks following a hypertensive crisis after routine administration of betamethasone. Postnatal persistence of signs and symptoms of catecholamine excess led to the diagnosis of a left adrenal pheochromocytoma. Between diagnosis and planned tumor removal, the patient developed signs and symptoms of Cushing's syndrome (facial edema and hirsutism, myopathy and fatigue). Biochemical testing confirmed hypercortisolism with extremely elevated levels of plasma adrenocorticotropin, urinary cortisol and multiple steroids of a plasma panel that were all normal at previous testing. The previously noradrenergic tumor also started producing epinephrine. Histopathological examination confirmed the pheochromocytoma, which was also immunohistochemically positive for adrenocorticotropin. Full post-surgical recovery was sustained with normal blood pressure and biochemical findings after one year. This report not only underlines the chameleon behavior of pheochromocytoma but also illustrates its potential for a metamorphosing presentation. Corticosteroid administration in pregnancy requires a cautious approach in patients with hypertension.

    Full Text Available Burning mouth syndrome (BMS is a relatively common disease that can severely affect the quality of life of the patient. It causes chronic orofacial pain or oral burning sensation even in the absence of any detectable organic cause. The etiology of BMS is complex and multifactorial. It has been associated with menopause, trigger events and even genetic polymorphisms. Although its etiology remains unclear, there is still much evidence that psychological elements like stress, anxiety or depression do play a significant role. There are several studies in the literature which only report the association of BMS with psychological factors. But to the best of our knowledge, there is no such case reported in the literature which has actually highlighted the management of such a case with psychogenic elements involved. In this case report, apart from discussing the role of psychological factors, the treatment of BMS with emphasis on counseling is also emphasized. Further, it is of interest to know that such patients with psychologically induced burning mouth syndrome have to be evaluated to their deepest details. Even their commonly overlooked gestures and habits like watching a particular television soap opera may be involved in their disease process. It can be concluded that psychological counseling in general dental practice can provide an effective cure for chronic oral burning sensation with psychological factors involved.

    Wolfram syndrome-1 is a rare and severe autosomal recessive neurodegenerative disease characterized by diabetes mellitus (DM), optic atrophy, diabetes insipidus, and deafness. Poorly controlled type 1 DM increases the risk for thrombosis. However, coexistence of DM and hereditary thrombosis factors is rarely observed. Here we present the case of a 13.5-year-old, nonfollowed girl newly diagnosed with poorly controlled Wolfram syndrome on the basis of the results of clinical and laboratory examinations. On the eighth day after diabetic ketoacidosis treatment, pulmonary embolism developed in the subject. Thrombus identified in the right atrium using echocardiography was treated by emergency thrombectomy. Homozygous mutation in the methylenetetrahydrofolate reductase gene C677T, heterozygous factor-V Leiden mutation, and active protein C resistance were identified in the patient. The patient was lost because of a recurring episode of pulmonary embolism on the 86th day of hospitalization. We present this case to highlight the need for investigating hereditary thrombosis risk factors in diabetic patients in whom thromboembolism develops.

    Drug-induced hypersensitivity syndrome (DIHS)/drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is characterized by late disease onset, fever, rash, hepatic dysfunction, haematological abnormalities, lymphadenopathy and often, human herpesvirus (HHV) reactivation. The diagnosis of DIHS is based on the combined presence of these findings. Anticonvulsants are a major cause of DIHS and may also cause Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). We examined whether SJS/TEN due to anticonvulsants display similar clinical and laboratory features seen in DIHS. Patients diagnosed with SJS or TEN due to anticonvulsants (n = 8) were examined and their clinical features and laboratory findings were compared with patients with anticonvulsant-related DIHS (n = 6). Seven of the eight patients with SJS/TEN developed symptoms > 3 weeks after starting anticonvulsants. Hepatic dysfunction was present in six patients with SJS/TEN and five patients with DIHS. Leucocytosis and/or eosinophilia was noted in seven patients with SJS/TEN and four patients with DIHS. Only one patient in the SJS/TEN group had atypical lymphocytosis; this was present in four patients with DIHS. Reactivation of HHV-6 was detected in one of the four patients tested in the SJS/TEN group, although it was seen in five of the six patients with DIHS. TSJS/TEN due to anticonvulsants may exhibit some clinical and laboratory features of DIHS. The nature of the cutaneous involvement should be emphasized in the diagnosis of DIHS. © 2009 The Author(s).

    Postoperative hemorrhage is a significant cause of morbidity and mortality following liver resection. It typically presents early within the postoperative period, and conservative management is possible in the majority of cases. We present a case of late post-hepatectomy hemorrhage associated with overt abdominal compartment syndrome resulting from a localized functional compartment within the abdomen. A 68-year-old white man was readmitted with sudden onset of upper abdominal pain, vomiting, and hemodynamic instability 8 days after an uneventful hepatic resection for metachronous colon cancer metastasis. A frozen abdomen with adhesions due to complicated previous abdominal surgeries was encountered at the first intervention, but the surgery itself and initial recovery were otherwise unremarkable. Prompt response to fluid resuscitation at admission was followed by a computed tomography of his abdomen that revealed active arterial hemorrhage in the liver resection site and hemoperitoneum (estimated volume abdominal compartment syndrome. Surgical exploration confirmed a small volume of ascites and blood clots (1.2 L) under significant pressure in his supramesocolic region, restricted by his frozen lower abdomen, which we evacuated. Dramatic improvement in his ventilatory pressure was immediate. His abdomen was left open and a negative pressure device was placed for temporary abdominal closure. The fascia was formally closed after 48 hours. He was discharged home at postoperative day 6. Intra-abdominal pressure and radiologic findings of intra-abdominal hemorrhage should be carefully interpreted in patients with extensive intra-abdominal adhesions. A high index of suspicion and detailed understanding of abdominal compartment mechanics are paramount for the timely diagnosis of abdominal compartment syndrome in these patients. Clinicians should be aware that abnormal anatomy (such as adhesions) coupled with localized pathophysiology (such as hemorrhage) can create a so

  8. Sweet Taste Receptor Signaling Network: Possible Implication for Cognitive Functioning

    2015-01-01

    Full Text Available Sweet taste receptors are transmembrane protein network specialized in the transmission of information from special “sweet” molecules into the intracellular domain. These receptors can sense the taste of a range of molecules and transmit the information downstream to several acceptors, modulate cell specific functions and metabolism, and mediate cell-to-cell coupling through paracrine mechanism. Recent reports indicate that sweet taste receptors are widely distributed in the body and serves specific function relative to their localization. Due to their pleiotropic signaling properties and multisubstrate ligand affinity, sweet taste receptors are able to cooperatively bind multiple substances and mediate signaling by other receptors. Based on increasing evidence about the role of these receptors in the initiation and control of absorption and metabolism, and the pivotal role of metabolic (glucose regulation in the central nervous system functioning, we propose a possible implication of sweet taste receptor signaling in modulating cognitive functioning.

    The intriguing observation that leptin decreases sweet-evoked peripheral gustatory responses has aroused much interest (Kawai K, Sugimoto K, Nakashima K, Miura H, Ninomiya Y. 2000. Leptin as a modulator of sweet taste sensitivities in mice. Proc Natl Acad Sci U S A. 97(20):11044-11049.) due to its implied importance in controlling appetite. The effects of this anorexic hormone, however, appear more conditional than originally believed. In this issue of Chemical Senses, a careful study by Glendinning and colleagues, find no effects of leptin on sweet-evoked chorda tympani responses, whereas an equally careful study by Meredith and colleagues, find decreased release of ATP and increased release of 5-HT from taste buds in response to sweet stimuli. © The Author 2015.

    Waardenburg syndrome (WS) is a rare disorder comprising sensorineural deafness and pigmentation abnormalities. Four distinct subtypes are defined based on the presence or absence of additional symptoms. Mutations in six genes have been described in WS. SOX10 mutations are usually associated with a more severe phenotype of WS with peripheral demyelinating neuropathy, central dysmyelinating leukodystrophy, and Hirschsprung disease. Here we report a 32-year-old man with a novel heterozygous missense variant in SOX10 gene, who presented with congenital deafness, Hirschsprung disease, iris heterochromia, foot deformity, and intermediate conduction velocity length-dependent sensorimotor neuropathy. This case highlights that the presence of other non-neuropathic features in a patient with presumed hereditary neuropathy should alert the clinician to possible atypical rare causes. © 2017 Peripheral Nerve Society.

    Rubella virus infection during the first trimester of pregnancy can cause congenital rubella syndrome (CRS). We aimed to describe the abnormalities in order to define the ultrasound features to look for when performing prenatal scans. The goal of this review is to focus specifically on the signs of CRS accessible to prenatal diagnosis. We analyzed every case of CRS described before and/or after birth that we identified in the Pubmed database and classified them as accessible or not to prenatal diagnosis. The most frequently reported malformations accessible to prenatal diagnosis were: cardiac septal defects, pulmonary artery stenosis, microcephaly, cataract, microphtalmia, and hepatosplenomegaly. This extensive literature review shows that the ultrasound features of CRS are not well known, even though rubella was the first teratogenic virus described. This review will help clinicians in the management of rubella during pregnancy by clarifying the findings to be sought.

    Full Text Available ABSTRACT We report one patient with Klippel-Feil (KFS syndrome, other associated anomalies, uncontrolled arterial hypertension, and renal artery stenosis. Because this patient underwent for surgical revascularization with unsuccessful result, all proposed way of treatments are revised, and we have hypothesized that probably for patients with KFS and unilateral renal artery stenosis, medical treatment with ACE inhibitors can provide more benefits than surgical revascularization or percutaneous transluminal angioplasty. We considered that those patients should be manage by a team of medical doctors being aware of their common associated anomalies, identifying all of them when it is possible then, making an integral evaluation of the each individual situation for establishing their medical priorities in order, and then address its treatments accordingly. If at this stage any surgical treatment is required, is important to bring those problems to the anesthesiologist’s attention for a very careful manipulation of the neck and head during induction of anesthesia. The final results will be strongly related with the capacity of management of the underlying cardio-respiratory, renal, skeletal, urogenital, and nervous system problems. . We also propose the term of Klippel-Feil syndrome "Plus" for those patients with cervical vertebral fusion and many other associated deformities rather than to add new eponyms to the long list that already exist. _____________ RESUMEN: HIPERTENSION RENOVASCULAR DEBIDO A ESTENOSIS DE LA ARTERIA RENAL EN EL SÍNDROME DE KLIPPEL-FEIL Reportamos un paciente afectado por un syndrome de Klippel-Feil, otras anormalias congenitas, hipertension arterial incontrolada y una estenosis unilateral de la arteria renal.

    Gouty tophi is a rare cause of CTS. We first report a unique case of repeated CTS with gouty tophi in flexor tendon. In the previous literature, the symptoms cases of CTS were gradually increased. We report a 44-year-old male porter presented with mass on his left distal forearm combined a repeated carpal tunnel syndrome for 5 years. He felt numbness in fingers and his left palmar. The CTS symptoms had been eased through rest and dugs medication. It recurred twice. Monosodium urate crystal deposits were found in surgery. Histologic findings confirmed the diagnosis of gout. We removed partial of gouty tophus and retained the integrity of the tendon. Two years after the surgery, the patient had not experienced any symptom recurrence. Early diagnosis and control of gout are necessary to avoid irreversible complications. The surgery combined with decreasing trioxypurine treatment can improve the treatment outcome of gouty tophus.

    A 41-year-old woman with a history of asthma arrived at the emergency room of our hospital with dyspnea. The electrocardiogram showed no specific results. Echocardiography defects revealed an obvious decrease in the left ventricular systolic function and enlargement of the left chamber. We initially considered her condition to be dilated cardiomyopathy. However, she had eosinophilia in the peripheral blood and elevated cardiac enzymes. The coronary angiography showed normal coronary arteries. Single photon emission computed tomography (SPECT) showed infiltrative myocardial disease. She was then diagnosed with eosinophil infiltrations. Combined with peripheral nerve injury and lung involvement, she was diagnosed as having Churg-Strauss syndrome. After initiating prednisone treatment, her eosinophilia and rising cardiac enzymes recovered to normal, and both her echocardiographic abnormalities and symptoms noticeably improved.

    2016-01-01

    Full Text Available Although posterior reversible encephalopathy syndrome (PRES is rarely associated with subarachnoid hemorrhage, to our knowledge, rupture of a concomitant cerebral aneurysm following PRES has not been reported. We describe a patient with atypical PRES involving the brainstem, thalamus, and periventricular white matter without cortical or subcortical edema of the parietooccipital lobe on magnetic resonance imaging, with rupture of a concomitant cerebral aneurysm. Preexisting extremely high blood pressure may trigger atypical PRES, and failure to lower blood pressure may lead to a concomitant aneurysm rupture. In the future treatment of hypertensive urgency with a recurrence of symptoms and mean arterial blood pressure >150 mmHg, it is advisable to immediately hospitalize the patient for aggressive blood pressure management, especially if PRES is suspected based on clinical and radiological features.

    Symptoms of hypopituitarism are usually chronic and nonspecific, but rarely the disease can have acute and life threatening manifestations. We report a 53 years old female with a pituitary adenoma that was admitted to our hospital because of syncope. The electrocardiogram showed sinus bradycardia with a prolonged QT interval. Frequent runs of non-sustained polymorphic ventricular tachycardia were noted on telemetry. The patient had a history of severe acute headaches in the previous days and laboratory tests revealed severe secondary hypothyroidism, adrenal insufficiency and a decrease in pituitary hormones. A magnetic resonance imaging of the head showed changes in the size and contrast enhancement of the adenoma. A diagnosis of hypopituitarism secondary to pituitary apoplexy was made and treatment with hydrocortisone and, subsequently, levothyroxine was started. Hormonal disorders such as hypothyroidism, adrenal insufficiency or hypopituitarism should be considered as unusual causes for reversible cardiomyopathy, long QT syndrome and ventricular arrhythmias.

    Acute thyroiditis is an extremely rare complication of nocardiosis. We report a patient with hyperthyroidism due to suppurative thyroiditis caused by Nocardia brasiliensis. A 38-year-old Black male presented with features of thyrotoxicosis, sepsis and airway obstruction. He had no evidence of underlying thyroid disease, but was severely immunocompromised as a result of acquired immunodeficiency syndrome. He had previously been diagnosed with pulmonary nocardiosis and also had nocardial abscesses on his anterior chest wall. Investigations revealed thyrotoxicosis, with a FT4 of 43.2 pmol/l and a suppressed TSH Nocardia.

    We report the case of a 19-year-old Chinese female harboring the m.3291T>C mutation in the MT-TL1 gene encoding the mitochondrial transfer RNA for leucine. She presented with a complex phenotype characterized by progressive cerebellar ataxia, frequent myoclonus seizures, recurrent stroke-like episodes, migraine-like headaches with nausea and vomiting, and elevated resting lactate blood level. It is known that the myoclonus epilepsy with ragged-red fibers (MERRF) is characterized by cerebellar ataxia and myoclonus epilepsy, while that the mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is characterized by recurrent stroke-like episodes, migraine-like headaches, and elevated resting lactate blood level. So the patient's clinical manifestations suggest the presence of a MERRF/MELAS overlap syndrome. Muscle biopsy of the patient showed the presence of numerous scattered ragged-red fibers, some cytochrome c oxidase-deficient fibers, and several strongly succinate dehygrogenase-reactive vessels, suggestive of a mitochondrial disorder. Direct sequencing of the complete mitochondrial genome of the proband revealed no mutations other than the T-to-C transition at nucleotide position 3291. Restriction fragment length polymorphism analysis of the proband and her family revealed maternal inheritance of the mutation in a heteroplasmic manner. The analysis of aerobic respiration and glycolysis demonstrated that the fibroblasts from the patient had mitochondrial dysfunction. Our results suggest that the m.3291T>C is pathogenic. This study is the first to describe the m.3291T>C mutation in association with the MERRF/MELAS overlap syndrome.

    Mitochondrial DNA depletion syndrome (MDS) is characterized by a reduction in mtDNA copy number and has been associated with mutations in eight nuclear genes, including enzymes involved in mitochondrial nucleotide metabolism (POLG, TK2, DGUOK, SUCLA2, SUCLG1, PEO1) and MPV17. Recently, mutations in the RRM2B gene, encoding the p53-controlled ribonucleotide reductase subunit, have been described in seven infants from four families, who presented with various combinations of hypotonia, tubulopathy, seizures, respiratory distress, diarrhea, and lactic acidosis. All children died before 4 months of age. We sequenced the RRM2B gene in three unrelated cases with unexplained severe mtDNA depletion. The first patient developed intractable diarrhea, profound weakness, respiratory distress, and died at 3 months. The other two unrelated patients had a much milder phenotype and are still alive at ages 27 and 36 months. All three patients had lactic acidosis and severe depletion of mtDNA in muscle. Muscle histochemistry showed RRF and COX deficiency. Sequencing the RRM2B gene revealed three missense mutations and two single nucleotide deletions in exons 6, 8, and 9, confirming that RRM2B mutations are important causes of MDS and that the clinical phenotype is heterogeneous and not invariably fatal in infancy.

    Reactive airway dysfunction syndrome (RADS) is a type of non-immunologically mediated asthma-like disease. It usually occurs after a massive exposure to an irritating substance in the atmosphere in the form of smoke, fumes, gases, and vapor. Unlike bronchial asthma, there is no latency to the symptoms seen in RADS. A number of agents are known to cause RADS, but tile dust, as an etiological agent, has not been previously reported. We report a 45-year-old male laborer, who presented with an acute onset of cough, chest tightness, breathlessness, and audible wheeze after his first time exposure to porcelain tile dust within 5 hours of exposure. Lab tests, including, chest X-ray, electrocardiogram, air blood gas analysis, and serum IgE, were unremarkable. Spirometry showed a mild obstruction [forced expiratory volume in 1 second (FEV1)=72% of predicted], while the bronchodilator reversibility test was significant(14% increase in FEV1 above the baseline).Bronchial biopsy revealed a chronic inflammatory reaction with lymphocytic and plasma cell infiltration and more importantly a striking absence of eosinophils. To the best of our knowledge, this is the first reported case of RADS as a result of exposure to tile dust (porcelain ceramics).

  2. Occult Breast Cancer due to Multiple Calcified Hamartomas in a Patient with Cowden Syndrome

    Directory of Open Access Journals (Sweden)

    E. B. Gómez García

    2012-01-01

    Full Text Available Cowden syndrome (CS is an autosomal dominant disorder characterized by presence of multiple hamartomas, and other benign and malignant abnormalities of the breasts, skin, thyroid, endometrium, gastrointestinal tract, and central nervous system. Hamartomas are benign, developmentally disorganized tumors that can develop in any of the above mentioned organs. The presence of massive calcifications in the breasts in very young women is an indication to perform a breast MRI to exclude a neoplasm since, like in the current case report, presence of breast calcifications may obscure a neoplasm. Although fibrocystic disease and cooccurrence of fibrocystic disease and breast cancer are much more common than CS, the presence of massive calcifications in the breasts of very young women should elicit the possibility of an underlying genetic disease. Furthermore, breast cancer and macrocephaly are considered major criteria for the diagnosis of CS and the combination of both is enough to establish the clinical diagnosis of this entity. Fibrocystic disease of the breasts and multinodular goiter are minor criteria. Family history is also important for the diagnosis of (any hereditary disease.

    Androgen insensitivity syndrome (AIS) is the most frequent etiology of 46,XY disorders of sex development (DSDs), and it is an X-linked disorder caused by mutations in the androgen receptor (AR) gene. AIS patients present a broad phenotypic spectrum and individuals with a partial phenotype present with different degrees of undervirilized external genitalia. There are more than 500 different AR gene allelic variants reported to be linked to AIS, but the presence of somatic mosaicisms has been rarely identified. In the presence of a wild-type AR gene, a significant degree of spontaneous virilization at puberty can be observed, and it could influence the gender assignment, genetic counseling and the clinical and psychological management of these patients and the psychosexual outcomes of these patients are not known. In this study, we report two patients with AR allelic variants in heterozygous (c.382G>T and c.1769-1G>C) causing a partial AIS (PAIS) phenotype. The first patient was raised as female and she had undergone a gonadectomy at puberty. In both patients there was congruency between gender of rearing and gender identity and gender role. Somatic mosaicism is rare in AIS and nonsense AR variant allelic can cause partial AIS phenotype in this situation. Despite the risk of virilization and prenatal androgen exposure, the gender identity and gender role was concordant with sex of rearing in both cases. A better testosterone response can be expected in male individuals and this should be considered in the clinical management.

    Creutzfeldt-Jakob disease (CJD) is a rare, rapidly progressive, and fatal neurodegenerative disease with neuropsychological sequelae. This study highlighted a rare presentation of CJD (e.g. corticobasal syndrome [CBS]), reviewed updated diagnostic criteria and procedures for CJD (e.g. diffusion weighted imaging [DWI], real-time quaking-induced conversion [RT-QuIC]), and discussed differential diagnoses. Case report methodology focused on a 68-year-old, Hispanic, right-handed man with 11 years of education. He presented with a 1-2-month history of gait and motor difficulties (e.g. rigidity, myoclonus). After evaluation, a 'cortical ribboning' pattern on DWI and positive RT-QuIC was integrated with performance on neurobehavioral exam (i.e. alien limb phenomenon, unilateral ideomotor apraxia) and neuropsychological testing (i.e. frontal-parietal dysfunction pattern) to reach a diagnosis of sCJD-CBS. The patient expired 3 months after onset of symptoms. This literature review and case report highlighted the importance of staying abreast of developments in neurological literature and the added value of neuropsychology, when integrated with newer procedures, for confirming and excluding diagnostic considerations.

    Maternal uniparental disomy (UPD) 15 is one of the molecular causes of Prader-Willi syndrome (PWS), a multisystem disorder which presents with neonatal hypotonia and feeding difficulty. Current diagnostic algorithms differ regarding the use of SNP microarray to detect PWS. We retrospectively examined the frequency with which SNP microarray could identify regions of homozygosity (ROH) in patients with PWS. We determined that 7/12 (58%) patients with previously confirmed PWS by methylation analysis and microsatellite-positive UPD studies had ROH (>10 Mb) by SNP microarray. Additional assessment of 5,000 clinical microarrays, performed from 2013 to present, determined that only a single case of ROH for chromosome 15 was not caused by an imprinting disorder or identity by descent. We observed that ROH for chromosome 15 is rarely incidental and strongly associated with hypotonic infants having features of PWS. Although UPD microsatellite studies remain essential to definitively establish the presence of UPD, SNP microarray has important utility in the timely diagnostic algorithm for PWS. © 2017 S.

    Diencephalic Syndrome is a rare clinical condition of failure to thrive despite a normal caloric intake, hyperalertness, hyperkinesis, and euphoria usually associated with low-grade hypothalamic astrocytomas. We reported an unusual case of diencephalic cachexia due to hypothalamic anaplastic astrocytoma (WHO-grade III). Baseline endocrine function evaluation was performed in this patient before surgery. After histological diagnosis, he enrolled to a chemotherapy program with sequential high-dose chemotherapy followed by hematopoietic stem cell rescue. The last MRI evaluation showed a good response. The patient is still alive with good visual function 21 months after starting chemotherapy. Diencephalic cachexia can rarely be due to high-grade hypothalamic astrocytoma. We suggest that a nutritional support with chemotherapy given to high doses without radiotherapy could be an effective strategy for treatment of a poor-prognosis disease.

    Cushing's syndrome due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions has occasionally been described. We retrospectively reviewed all 164 cases of Cushing's syndrome and 77 cases of pheochromocytomas during 10 years. Of all cases with Cushing's syndrome, only two cases (1.2 %) were due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions (one case of pheochromocytoma and one case of adrenal medullary hyperplasia). Of all pheochromocytomas only the above-mentioned case (1.3 %) also gave rise to an ectopic adrenocorticotropic hormone syndrome. The clinical presentation of adrenocorticotropic hormone-secreting pheochromocytoma and adrenal medullary hyperplasia can be anything from mild to dramatic. These are rare conditions important to bear in mind in the workup of a patient with Cushing's syndrome or with pheochromocytoma. The identification of ectopic adrenocorticotropic hormone secretion from adrenal medullary lesions can be life-saving.

    PURPOSE. To determine the disease course in Usher syndrome type IB (USH1B) caused by myosin 7A (MYO7A) gene mutations. METHODS. USH1B patients (n = 33, ages 2-61) representing 25 different families were studied by ocular examination, kinetic and chromatic static perimetry, dark adaptometry, and optical coherence tomography (OCT). Consequences of the mutant alleles were predicted. RESULTS. All MYO7A patients had severely abnormal ERGs, but kinetic fields revealed regional patterns of visual loss that suggested a disease sequence. Rod-mediated vision could be lost to different degrees in the first decades of life. Cone vision followed a more predictable and slower decline. Central vision ranged from normal to reduced in the first four decades of life and thereafter was severely abnormal. Dark adaptation kinetics was normal. Photoreceptor layer thickness in a wide region of central retina could differ dramatically between patients of comparable ages; and there were examples of severe losses in childhood as well as relative preservation in patients in the third decade of life. Comparisons were made between the mutant alleles in mild versus more severe phenotypes. CONCLUSIONS. A disease sequence in USH1B leads from generally full but impaired visual fields to residual small central islands. At most disease stages, there was preserved temporal peripheral field, a potential target for early phase clinical trials of gene therapy. From data comparing patients' rod disease in this cohort, the authors speculate that null MYO7A alleles could be associated with milder dysfunction and fewer photoreceptor structural losses at ages when other genotypes show more severe phenotypes.

    L-Cysteine, glutathione, inosine, and cepharanthin are the agents which have been widely used to prevent and treat the leukopenic syndrome following radiotherapy. Among these, the efficacy of inosine has been demonstrated in a double-blind comparative study. A double-blind controlled study of L-Cysteine compared to inosine and lactose-placebo was performed. Patients designated to receive radiotherapy for cancer of the lung, breast and uterine cervix were randomly allocated to 3 groups; namely, those to receive L-Cysteine 480 mg TID (CG group), inosine 1,800 mg TID (IN group) and placebo capsules (PL group) for 6 to 7 weeks. Among 159 cases, 152 were subjected to statistical analyses, and the latter consisted of 54 CG, 52 IN and 46 PL subjects. Any discrepancies among these 3 groups concerning sex, age, disease, WBC count, radiation procedure, or combined use of carcinostatics were negligible. According to the life-table analysis, the cumulative rates for the 3 groups were compared with respect to maintenance of WBC counts higher than 4,000/mm/sup 3/. Maintenance was best in the CG group, intermediate in the IN, and poorest in the PL group, the difference between CG and PL being statistically significant at the 5% level. Similar results were obtained in separate analyses of strata with and without concomitant carcinostatics. Furthermore, nearly the same results were obtained as those in the life-table analyses when data concerning efficacy and clinical usefulness as judged by physicians were analyzed. The present study indicates that the oral administration of L-Cysteine is safe and effective in preventing and treating leukopenic complications associated with radiotherapy.

    Invasive pneumococcal disease is an uncommon and notifiable disease in Singapore. It is often associated with significant morbidity and mortality. We report a rare case of invasive pneumococcal bacteraemia due to parotitis in a patient with systemic sclerosis and secondary Sjögren's syndrome. We also present a retrospective review of Streptococcus pneumoniae bacteraemia cases in Singapore General Hospital from January 2011 to April 2016. A 59-year-old Malay lady with a history of systemic sclerosis with secondary Sjögren's syndrome presented with fever and left parotid gland swelling. Clinical examination revealed poor salivary pooling and left parotid swelling without fluctuance. Ultrasound of the left parotid gland confirmed acute parotitis without evidence of abscess or sialolithiasis. Blood cultures were positive for S. pneumoniae . She was diagnosed to have invasive pneumococcal bacteraemia secondary to acute parotitis, and treated with intravenous benzylpenicillin with clearance of bacteraemia after 3 days. Upon discharge, her antibiotics were changed to intravenous ceftriaxone to facilitate outpatient parenteral antibiotic therapy for another 2 weeks. She responded favourably to antibiotics at follow-up, with no complications from the bacteraemia. A review of the microbiological records of the Singapore General Hospital revealed 116 cases of pneumococcal bacteraemia, most (80.3 %) of which were due to pneumonia. None were due to parotitis. S. pneumoniae parotitis and subsequent bacteraemia is rare. Prompt recognition of the disease and appropriate use of antibiotics are important. This case highlights that close communication between healthcare workers (microbiologist, rheumatologist and infectious disease specialist) is essential in ensuring good clinical outcomes in patients with a potentially fatal disease.

    Full Text Available A 70-year-old male patient developed acute paraplegia due to conus medullaris compression secondary to extrusion of D12-L1 disc. After negative epidural examination intraoperatively, a durotomy was performed and an intradural disc fragment was excised. Patient did not regain ambulatory status at two-year follow-up. Intraoperative finding of negative extradural compression, tense swollen dura and CSF leak from ventral dura should alert the surgeon for the possibility of intradural disc herniation. A routine preoperative MRI is misleading and a high index of suspicion helps to avoid a missed diagnosis.

    To estimate breed-specific risk of death due to, and prevalence of, gastric dilatation-volvulus (GDV) in UK pedigree dogs. Data were available on the reported cause of and age at death and occurrence of and age at diagnosis of disease from the 2004 purebred dog health survey. A total of 15,881 dogs of 165 breeds had died in the previous 10 years; GDV was the cause of death in 65 breeds. There were 36,006 live dogs of 169 breeds of which 48 breeds had experienced > or =1 episodes of GDV. Prevalence ratios were used to estimate breed-specific GDV mortality and morbidity risks. Gastric dilatation-volvulus was the cause of death for 389 dogs, representing 2.5% (95% CI: 2.2-2.7) of all deaths reported and the median age at death was 7.92 years. There were 253 episodes in 238 live dogs. The median age at first diagnosis was five years. Breeds at greatest risk of GDV mortality were the bloodhound, Grand Bleu de Gascogne, German longhaired pointer and Neapolitan mastiff. Breeds at greatest risk of GDV morbidity were the Grand Bleu de Gascogne, bloodhound, otterhound, Irish setter and Weimaraner. These results suggest that 16 breeds, mainly large/giant, are at increased risk of morbidity/mortality due to GDV.

    The (18)F-FDG PET/CT scan has been suggested for whole-body imaging to identify ectopic adrenocorticotrophic hormone secreting tumours, but there are some challenges involved. The case of a patient is presented, who was admitted with the pre-diagnosis of ectopic ACTH syndrome. On the CT, a nodular lesion was detected in the medial segment of the right lung. The FDG uptake of the lesion seemed to be increased visually, but was not pathological quantitatively (SUVmax: 1.8) on the PET/CT. There was also diffuse increased uptake (SUVmax: 14.2) in the enlarged adrenal glands. The lesion was reported as a possible malignant lesion with low FDG affinity, such as a low grade neuroendocrine tumour, while the diffuse enlarged adrenal glands with high uptake were interpreted as diffusely hyperplasic, due to Cushing's syndrome. The patient was treated with a surgical wedge resection. The histopathological diagnosis confirmed that the tumour was a grade 1 well-differentiated neuroendocrine carcinoma.

    The most common form of renal involvement in Sjögren's syndrome (SS) is tubulointerstitial nephritis. Renal dysfunction is usually mild and subclinical. Glomerulonephritis (GMN) is rare in patients with SS. We report a 28-year-old multigravida patient with primary Sjögren's syndrome (pSS) and associated manifestations, who presented with acute renal failure in the 20th week of her fifth pregnancy. The complaints and clinical findings, positive Schirmer's test, findings of dry eye on ophthalmologic examination, and the salivary gland biopsy were compatible with SS. The patient exhibited no other clinical or laboratory findings indicative of other collagenous disease and/or rheumatoid arthritis. She refused renal biopsy, hesitating for fear of fetal loss; thus, based on the clinical and laboratory findings indicating rapidly progressive GMN and vasculitis, prednisolone, plasmapheresis, and one dose of cyclophosphamide were administered during the pregnancy. Hemodialysis five times weekly was performed. At the 28th week of gestation, she underwent a cesarean section due to early rupture of membranes and fetal distress. A healthy male boy was delivered. The renal biopsy performed 2 weeks after labor revealed mesangial proliferative glomerulonephritis. After the fourth cyclophosphamide treatment, her urinary output increased and she was discharged from the hemodialysis program. She remains in follow-up at our outpatient clinic free of hemodialysis for 4 months. This is the first report of mesangial proliferative GMN requiring dialysis in a pregnant pSS patient that has featured good maternal and fetal outcomes.

A 29 year old woman with history of a Whipple procedure for pancreatic cancer and nonalcoholic steatohepatitis cirrhosis presented with a massive upper gastrointestinal bleeding (UGIB likely from esophageal varices and developed hemorrhagic shock. Emergent upper endoscopy could not be performed due to hemodynamic instability. Therefore, a Minnesota Tube was placed emergently for balloon tamponade of the bleeding. A transjugular intrahepatic portosystemic shunt was also placed emergently to decrease bleeding by reducing portal pressure. By this time, the patient had received 4 liters of normal saline, 14 units of packed red blood cells, 6 units of platelets, and 4 units of fresh frozen plasma. The Minnesota tube did control the bleeding somewhat, however, there was continued bloody drainage from the stomach port of the Minnesota tube. The patient’s abdomen became remarkably distended and was dull to percussion throughout. A CT scan of the abdomen and pelvis revealed severe dilatation of ...

    A 34-year-old male patient complained of general fatigue, ascites, and edema of the lower extremities. A chest x-ray film showed atelectasis of the right lung and pleural effusion of the right side. Liver ultrasonography revealed stenosis of the middle and right hepatic veins. Venacavography revealed stenosis of the inferior vena cava and collateral circulation. Finally, abdominal NMR-CT clearly visualized lunate stenosis and antero-lateral deviation of the inferior vena cava. He was diagnosed as having secondary Budd-Chiari syndrome resulting from the deviation and stenosis of the inferior vena cava due to distortion of the surrounding tissues by the thickened pleura which was caused by chronic empyema.

    Full Text Available Objective: Ishemic bone disease has multifactorial etiologies. Cronic dental infections should be eliminated to prevent osteonecrosis of the jaw. Case report: We report an unusual case of osteonecrosis due to the pulpal-peridontal syndrome and subsequent pulp necrosis. A case of 38 year old woman who presented with exposed bone, 8 mm in diameter, in the lingual area of the right lower third molar. The patient was otherwise healthy and was not taking any medications. A detailed medical history showed no previous diseases. Patient denied any type of local trauma. A complete blood count showed no abnormalities. The panoramic radiograph revealed a deep periodontal pocket between teeth 47 and 48. The CBCT revealed a deep periodontal pocket between molars and bone sequestrum of the lingual plate. Topical treatment consisted of adhesive periodontal dressing based on the cellulose and betamethasone oitnment together with orabase, without improvement. Therefore, peroral amoxycillin was prescribed for a week. Since there was no improvement, the third molar was removed as well as necrotic bone; the alveolar bone was remodelled and utures were placed. After suturing, the whole area was covered using intraoral resorbable bandage. Microbial swab of the wound aspirate did not reveal polymorphonuclears or the presence of icroorganisms. Microbial swab of the biopsy specimen of the necrotic bone particle and sequestrum showed a large amount of gram-positive coccae, however, polymorphonuclears were not found. Histopathological analysis revealed acute chronic inflammation. One week after the surgery, the area healed completely. Conclusion: This case highlights the fact that in some patients bone exposure might develop due to the pulpal-peridontal syndrome i.e. pulp necrosis.

    Sweetness is one of the main drivers of consumer preference, and thus is given high priority in apple breeding programmes. Due to the complexity of sweetness evaluation, soluble solid content (SSC) is commonly used as an estimation of this trait. Nevertheless, it has been demonstrated that SSC and sweet taste are poorly correlated. Though individual sugar content may vary greatly between and within apple cultivars, no previous study has tried to investigate the relationship between the amount of individual sugars, or ratios of these, and apple sweetness. In this work, we quantified the major sugars (sucrose, glucose, fructose, xylose) and sorbitol and explored their influence on perceived sweetness in apple; we also related this to malic acid content, SSC and volatile compounds. Our data confirmed that the correlation between sweetness and SSC is weak. We found that sorbitol content correlates (similarly to SSC) with perceived sweetness better than any other single sugar or total sugar content. The single sugars show no differentiable importance in determining apple sweetness. Our predictive model based on partial least squares regression shows that after sorbitol and SSC, the most important contribution to apple sweetness is provided by several volatile compounds, mainly esters and farnesene.

    Our objective was to evaluate efficacy and patency of metallic stent placement for symptomatic Budd-Chiari syndrome (BCS) due to prothrombotic disorders. Eleven patients with proved BCS due to prothrombotic disorders were referred for endovascular treatment because of refractory ascites (n=9), abdominal pain (n=8), jaundice (n=6), and/or gastrointestinal bleeding (n=4). Stents were inserted for stenosed hepatic vein (n=7), inferior vena cava (n=2), or mesenterico-caval shunt (n=2). Clinical efficacy and stent patency was evaluated by clinical and Doppler follow-up. After a mean follow-up of 21 months, 6 patients had fully patent stents without reintervention (primary stent patency: 55%). Two patients with hepatic vein stenosis had stent thrombosis and died 4 months after procedure. Restenosis occurred in 3 cases (2 hepatic vein and 1 mesenterico-caval shunt stenosis) and were successfully treated by balloon angioplasty (n=2) and addition of new stents (n=1) leading to a 82% secondary stent patency. Of 9 patients with patent stent, 7 were asymptomatic (77%) at the end of the study. Stent placement is a safe and effective procedure to control of symptomatic BCS. Prothrombotic disorder does not seem to jeopardize patency in anticoagulated patients. (orig.)

    Full Text Available Cushing’s syndrome (CS due to ectopic adrenocorticotrophic hormone (ACTH is associated with a variety of tumours most of which arise in the thorax or abdomen. Prostate carcinoma is a rare but important cause of rapidly progressive CS. To report a case of severe CS due to ACTH production from prostate neuroendocrine carcinoma and summarise previous published cases. A 71-year-old male presented with profound hypokalaemia, oedema and new onset hypertension. The patient reported two weeks of weight gain, muscle weakness, labile mood and insomnia. CS due to ectopic ACTH production was confirmed with failure to suppress cortisol levels following low- and high-dose dexamethasone suppression tests in the presence of a markedly elevated ACTH and a normal pituitary MRI. Computed tomography demonstrated an enlarged prostate with features of malignancy, confirmed by MRI. Subsequent prostatic biopsy confirmed neuroendocrine carcinoma of small cell type and conventional adenocarcinoma of the prostate. Adrenal steroidogenesis blockade was commenced using ketoconazole and metyrapone. Complete biochemical control of CS and evidence of disease regression on imaging occurred after four cycles of chemotherapy with carboplatin and etoposide. By the sixth cycle, the patient demonstrated radiological progression followed by recurrence of CS and died nine months after initial presentation. Prostate neuroendocrine carcinoma is a rare cause of CS that can be rapidly fatal, and early aggressive treatment of the CS is important. In CS where the cause of EAS is unable to be identified, a pelvic source should be considered and imaging of the pelvis carefully reviewed.

    Hyperthyroidism with the syndrome of inappropriate secretion of TSH (SITSH) occurred by a decrease in hydrocortisone dose after surgery for Cushing's syndrome. This is a novel cause of SITSH. The aim of this study was to describe and discuss 2 cases of SITSH patients that were found after surgery for Cushing's syndrome. We also checked whether SITSH occurred in 7 consecutive patients with Cushing's syndrome after surgery. A 45-year-old Japanese woman with ACTH-independent Cushing's syndrome and a 37-year-old Japanese man with ACTH-dependent Cushing's syndrome presented SITSH caused by insufficient replacement of hydrocortisone for postoperative adrenal insufficiency. When the dose of hydrocortisone was reduced to less than 20 mg/d within 18 days after surgery, SITSH occurred in both cases. We examined whether the change of the hydrocortisone dose induced the secretion of TSH. Free T₃ and TSH were normalized by the hydrocortisone dose increase of 30 mg/d, and these were elevated by the dose decrease of 10 mg/d. We also checked TSH and thyroid hormone levels of the 7 consecutive patients with Cushing's syndrome after surgery. Six (66.6 %) of 9 patients showed SITSH. This is the first report that insufficient replacement of hydrocortisone after surgery for Cushing's syndrome caused SITSH. Hyperthyroidism by SITSH as well as adrenal insufficiency can contribute to withdrawal symptoms of hydrocortisone replacement. We need to consider the possibility of SITSH for the pathological evaluation of withdrawal syndrome of hydrocortisone replacement.

    With the purpose of evaluating adaptability to the freezing process of super sweet corn sh2 hybrids Krispy King, Victor and 324, 100 cobs of each type were frozen at -18 degrees C. After 120 days of storage, their chemical, microbiological and sensorial characteristics were compared with a sweet corn su. Industrial quality of the process of freezing and length and number of rows in cobs were also determined. Results revealed yields above 60% in frozen corns. Length and number of rows in cobs were acceptable. Most of the chemical characteristics of super sweet hybrids were not different from the sweet corn assayed at the 5% significance level. Moisture content and soluble solids of hybrid Victor, as well as total sugars of hybrid 324 were statistically different. All sh2 corns had higher pH values. During freezing, soluble solids concentration, sugars and acids decreased whereas pH increased. Frozen cobs exhibited acceptable microbiological rank, with low activities of mesophiles and total coliforms, absence of psychrophiles and fecal coliforms, and an appreciable amount of molds. In conclusion, sh2 hybrids adapted with no problems to the freezing process, they had lower contents of soluble solids and higher contents of total sugars, which almost doubled the amount of su corn; flavor, texture, sweetness and appearance of kernels were also better. Hybrid Victor was preferred by the evaluating panel and had an outstanding performance due to its yield and sensorial characteristics.

    60 Co γ-ray was used to irradiate newly-harvested sweet corn and the results showed that the effects of irradiation on soluble solids, sucrose, starch and total sugar were not significant. The viscosity of starch decreased with the increasing of irradiation dose. The preservation duration of irradiated sweet corn was 7 days longer than that of CK, and the sweet, smell, taste of sweet corn had no abnormal change

  15. Traumatic brain injury is unlikely precipitating Leigh syndrome due to the GJB2 mutation c.35delG

    Full Text Available With interest we read the article by Ashrafi et al. about a 14-year-old female who is regarded to have developed Leigh syndrome (LS after traumatic brain injury (TBI. We have the following comments and concerns:We do not agree with the notion that traumatic brain injury was the precipitating factor for LS. The patient had a history of hypoacusis, which is a typical clinical manifestation of a mitochondrial disorder (MID. Hypoacusis obviously had developed long before the TBI. Additionally, the patient was diagnosed with neuropathy of the peripheral nerves two months after TBI. It is rather unlikely that neuropathy was triggered by TBI and more likely it was already present before the trauma. Thus, the initial manifestations of LS in the presented patient were most likely hypoacusis followed by neuropathy and TBI only might have triggered the seizure but not the MID. Why was the patient put on phenytoin, which is well-known to be mitochondrion-toxic? Phenytoin may worsen epilepsy and MID in general and it is conceivable that in fact phenytoin was responsible for worsening of the phenotype and not the TBI. In a 16-year-old female with MELAS syndrome due to the mutation m.3243A>G, phenytoin caused intestinal pseudo-obstruction one month after intravenous phenytoin for status epilepticus. In a patient with Kearns-Sayre syndrome phenytoin decreased cerebrospinal fluid (CSF folate levels. In rat hepatocytes, phenytoin increased reactive oxygen species (ROS formation, decreased intracellular reduced glutathione, increased intracellular oxidised glutathione, and enhanced lipid peroxidation and mitochondrial damage. In a hepatic microsomal system, phenytoin decreased state-3 respiration, ATP synthesis, and the mitochondrial membrane potential. In this model, phenytoin increased state-4 respiration, impaired Ca++-uptake and release, and inhibited Ca++-induced swelling. It would be interesting to know how the GJB2 mutation was detected.

    Full Text Available Cannabinoid Hyperemesis Syndrome (CHS was first described in 2004. Due to its novelty, CHS is often unrecognized by clinicians leading to expensive workup of these patients with cyclical symptoms. It may take up to 9 years to diagnose CHS. CHS is characterized by cyclical nausea and vomiting, abdominal pain, and an unusual compulsion to take hot showers in the presence of chronic use of cannabinoids. Cannabicyclohexanol is a synthetic cannabinoid, popularly known as K2 spice. It is a popular marijuana alternative among teenagers and young adults since it is readily available as herbal incense. Unlike marijuana, many users know that K2 is not detected in conventional urine drug screens, allowing those users to conceal their intake from typical detection methods. Serum or urine gas chromatography mass spectrophotometry is diagnostic, though not widely available. Thus, it is imperative for clinicians to recognize CHS, even with negative UDS, to provide cost-effective care. We present a 38-year-old man with a 10-year history of cannabis, and 1-year history of K2 abuse admitted with 1-week history of episodes of nausea, vomiting of clear fluids, and epigastric discomfort. Symptoms are relieved only by hot showers. Extensive laboratory, radiologic, and endoscopic evaluation was unrevealing. CHS was diagnosed, based on proposed criteria by Simonetti et al.

    Full Text Available A 37-year-old Caucasian woman presented with acute decrease in central vision in her right eye and was found to have subfoveal choroidal neovascularization (CNV due to presumed ocular histoplasmosis syndrome (POHS. Her visual acuity improved from 20/70 to 20/20 at her 6-month follow-up, after 3 consecutive monthly intravitreal bevacizumab injections were initiated at her first visit. Although no CNV activity was seen on fluorescein angiography (FA or spectral-domain optical coherence tomography (SD-OCT at her 2-month, 4-month, and 6-month follow-up visits, persistent flow in the CNV lesion was detected on optical coherence tomography angiography (OCTA. OCTA shows persistent vascular flow as well as changes in vascular flow in CNV lesions associated with POHS, indicating the continued presence of patent vessels and changes in these CNV lesions, even when traditional imaging of the lesion with OCT and FA indicates stability of the lesion with no disease activity. Additional cases with longitudinal follow-up are needed to assess how OCTA should be incorporated into clinical practice.

    Sweet potatoes were ground and stored in a ground hold. The stored sweet potatoes gave about 90% fermentation efficiency by the koji process. A lower fermentation efficiency by the amylo process was improved by adding 20 to 30 mg/100 ml of organic N. Inorganic N has no effect in improving the fermentation efficiency of the stored sweet potatoes by the amylo process.

    Leigh syndrome (LS) is a progressive untreatable degenerating mitochondrial disorder caused by either mitochondrial or nuclear DNA mutations. A patient was a second child of unconsanguineous parents. On the third day of birth, he was transferred to neonatal intensive care units because of severe lactic acidosis. Since he was showing continuous lactic acidosis, the oral supplementation of dichloroacetate (DCA) was introduced on 31st day of birth at initial dose of 50 mg/kg, followed by maintenance dose of 25 mg/kg/every 12 h. The patient was diagnosed with LS due to a point mutation of an A-C at nucleotide 599 in exon 6 in the pyruvate dehydrogenase E1α gene, resulting in the substitution of aspartate for threonine at position 200 (N200T). Although the concentrations of lactate and pyruvate in blood were slightly decreased, his clinical conditions were deteriorating progressively. In order to overcome the mitochondrial or cytosolic energy crisis indicated by lactic acidosis as well as clinical symptoms, we terminated the DCA and administered 0.5 g/kg/day TID of sodium pyruvate orally. We analyzed the therapeutic effects of DCA or sodium pyruvate in the patient, and found that pyruvate therapy significantly decreased lactate, pyruvate and alanine levels, showed no adverse effects such as severe neuropathy seen in DCA, and had better clinical response on development and epilepsy. Though the efficacy of pyruvate on LS will be evaluated by randomized double-blind placebo-controlled study design in future, pyruvate therapy is a possible candidate for therapeutic choice for currently incurable mitochondrial disorders such as LS.

    A range of psychophysical taste measurements are used to characterize an individual's sweet taste perception and to assess links between taste perception and dietary intake. The aims of this study were to investigate the relationship between four different psychophysical measurements of sweet taste perception, and to explore which measures of sweet taste perception relate to sweet food intake. Forty-four women aged 20-40 years were recruited for the study. Four measures of sweet taste perception (detection and recognition thresholds, and sweet taste intensity and hedonic liking of suprathreshold concentrations) were assessed using glucose as the tastant. Dietary measurements included a four-day weighed food record, a sweet food-food frequency questionnaire and a sweet beverage liking questionnaire. Glucose detection and recognition thresholds showed no correlation with suprathreshold taste measurements or any dietary intake measurement. Importantly, sweet taste intensity correlated negatively with total energy and carbohydrate (starch, total sugar, fructose, glucose) intakes, frequency of sweet food intake and sweet beverage liking. Furthermore, sweet hedonic liking correlated positively with total energy and carbohydrate (total sugar, fructose, glucose) intakes. The present study shows a clear link between sweet taste intensity and hedonic liking with sweet food liking, and total energy, carbohydrate and sugar intake.

    Wolfram syndrome is an autosomal recessive disorder caused by mutations in WFS1 and is characterized by insulin-dependent diabetes mellitus, optic atrophy, and deafness. To investigate the cause of β-cell failure, we used induced pluripotent stem cells to create insulin-producing cells from individuals with Wolfram syndrome. WFS1-deficient β-cells showed increased levels of endoplasmic reticulum (ER) stress molecules and decreased insulin content. Upon exposure to experimental ER stress, Wolfram β-cells showed impaired insulin processing and failed to increase insulin secretion in response to glucose and other secretagogues. Importantly, 4-phenyl butyric acid, a chemical protein folding and trafficking chaperone, restored normal insulin synthesis and the ability to upregulate insulin secretion. These studies show that ER stress plays a central role in β-cell failure in Wolfram syndrome and indicate that chemical chaperones might have therapeutic relevance under conditions of ER stress in Wolfram syndrome and other forms of diabetes.

    Cardiovascular surgery in the setting of chest wall deformities is a clinical challenge. Pectus excavatum, for example, can cause heart displacement to the left thoracic cavity, following the poor operative field. This report highlights a case in which a successful aortic valve-sparing operation via conventional median sternotomy after correction of the heart displacement due to pectus excavatum using Nuss procedure in Marfan syndrome. This technique can be one surgical option in Marfan syndrome patients with pectus excavatum and thoracic aortic aneurysm under close follow up.

  9. Hyponatremia in aneurysmal subarachnoid hemorrhage is due to the syndrome of inappropriate antidiuresis and acute glucocorticoid deficiency

    Hyponatraemia is the most common electrolyte abnormality following subarachnoid haemorrhage (SAH) and contributes to increased morbidity and mortality. Retrospective data suggests that the syndrome of inappropriate diuresis (SIAD) is the most common cause of hyponatraemia in SAH, though cerebral salt wasting has been postulated by some workers to be the predominant abnormality. Data which has shown acute glucocorticoid deficiency following SAH has suggested that some cases of euvolaemic hyponatraemia may also be caused by this mechanism.We prospectively studied the hormonal and haemodynamic influences involved in the development of hyponatraemia in 100 patients (61% female, median age 53 (range 16-82)) with non-traumatic aneurysmal SAH. Each patient had plasma sodium (pNa), urea, osmolality, glucose and 0900h cortisol (PC), and urinary sodium and osmolality measured on days 1, 2, 3, 4, 6, 8, 10 and 12 following SAH. Fluid balance and haemodynamic parameters were recorded daily. Results were compared with 15 patients admitted to ITU following vascular surgery. A PC<300nmol\\/L in a patient in ITU was regarded clinically as inappropriately low.49% of patients developed hyponatraemia (pNa<135 mmol\\/L), including 14% who developed clinically significantly hyponatraemia (pNa<130 mmol\\/L). 36\\/49 (73.4%) developed hyponatraemia between days 1 and 3 post SAH. The median duration of hyponatraemia was 3 days (range 1–10 days).In 35\\/49 (71.4%), hyponatraemia was due to SIAD as defined by standard diagnostic criteria. 14% of SAH patients had at least one PC<300nmol\\/L; 5 of these (35.7%) developed hyponatraemia. In 4 patients hyponatraemia was preceded by acute cortisol deficiency and responded to hydrocortisone treatment. In contrast, all controls had PC>500 nmol\\/L on day 1, and >300 nmol on days 3–12. There were no cases of cerebral salt wasting. There was no relationship between the incidence of hyponatraemia and the defined anatomical territory or severity of

    Carvajal syndrome is an autosomal dominant or autosomal recessive disorder, manifesting with dilated cardiomyopathy, woolly hair, and palmoplantar keratoma. Additional manifestations can be occasionally found. Carvajal syndrome may be due to mutations in the desmocollin-2, desmoplakin, or plakophilin-2 gene. We report a family with Carvajal syndrome which additionally presented with hypoacusis, noncompaction, recurrent pharyngeal infections, oligodontia, and recurrent diarrhoea. Father and brother were also affected and had died suddenly, the father despite implantation of a cardioverter defibrillator (ICD). Genetic studies revealed the novel pathogenic mutation c.1678A > T in the desmoplakin gene resulting in the amino acid change Ile to Phe at position 560 in the index case and her brother. The index case underwent ICD implantation recently. Phenotypic manifestations of Carvajal syndrome are even broader than so far anticipated, the number of mutations in the desmoplakin gene responsible for Carvajal syndrome is still increasing, and these patients require implantation of an ICD as soon as their diagnosis is established.

    Turner syndrome presents with one of the most frequent chromosomal aberrations in female, typically presented with growth retardation, ovarian insufficiency, facial dysmorphism, and numerous other somatic stigmata. Gigantism is an extremely rare condition resulting from an excessive growth hormone (GH) secretion that occurs during childhood before the fusion of epiphyseal growth plates. The major clinical feature of gigantism is growth acceleration, although these patients also suffer from hypogonadism and soft tissue hypertrophy. We presented a girl with mosaic Turner syndrome, delayed puberty and normal linear growth for the sex and age, due to the simultaneous GH hypersecretion by pituitary tumor. In the presented case all the typical phenotypic stigmata related to Turner syndrome were missing. Due to excessive pituitary GH secretion during the period while the epiphyseal growth plates of the long bones are still open, characteristic stagnation in longitudinal growth has not been demonstrated. The patient presented with delayed puberty and primary amenorrhea along with a sudden appearance of clinical signs of hypersomatotropinism, which were the reasons for seeking medical help at the age of 16. Physical examination of children presenting with delayed puberty but without growth arrest must include an overall hormonal and genetic testing even in the cases when typical clinical presentations of genetic disorder are absent. To the best of our knowledge, this is the first reported case of simultaneous presence of Turner syndrome and gigantism in the literature.

    Saccharated ferric oxide has been shown to lead to elevation of fibroblast growth factor 23, hypophosphatemia, and, consequently, osteomalacia. Moreover, mineral imbalance is often observed in patients with short-bowel syndrome to some degree. A 62-year-old woman with short-bowel syndrome related with multiple resections of small intestines due to Crohn disease received regular intravenous administration of saccharated ferric oxide. Over the course of treatment, she was diagnosed with tetany, which was attributed to hypocalcemia. Additional assessments of the patient revealed not only hypocalcemia, but also hypophosphatemia, hypomagnesemia, osteomalacia, and a high concentration of fibroblast growth factor 23 (314 pg/mL). We diagnosed her with mineral imbalance-induced osteomalacia due to saccharated ferric oxide and short-bowel syndrome. Magnesium replacement therapy and discontinuation of saccharated ferric oxide alone. These treatments were able to normalize her serum mineral levels and increase her bone mineral density. This case suggests that adequate evaluation of serum minerals, including phosphate and magnesium, during saccharated ferric oxide administration may be necessary, especially in patients with short-bowel syndrome.

    Full Text Available A middle aged male presented with acute bilateral vision loss, 4 weeks after undergoing gastric bypass surgery for gastric carcinoma. He had normal sensorium, fundoscopy, normal pupillary reaction to light, but had mild opthalmoparesis and nystagmus with ataxia. Magnetic resonance imaging of the brain revealed post-chiasmatic optic tract edema along with other classical features of Wernicke′s syndrome. Thiamine supplementation leads to complete resolution of clinical as well as imaging findings. In appropriate clinical settings, a high index of suspicion and early treatment are essential for managing Wernicke′s syndrome even in patients with atypical clinical and imaging presentation.

    1978-05-01

    A 5-months-old female baby with Down's Syndrome developed an intermittent spastic ectropion of the upper eyelids. The reasons for this are thought to be the flaccidity of the connective tissue, which is typical in Down's Syndrome, and a little anomaly of the eyelids, the tarsus was too short horizontally and very weak and the upper eyelids were somewhat larger than normal and elongated. Suturing Bangerter's lid-sheets on the upper eyelids for 15 days resulted in a scarring of the tarsus with the lax connective tissue of the upper eyelids. The ectropion disappeared and did not recur.

    Valdeorras (the N.W. corner of Spain) wants to promote the production and marketing of new sweet wines. The present work represents the first study on sweet wines manufactured with red grapes Vitis vinifera L. Garnacha Tintorera, a teinturier cultivar. Two different red sweet wines were elaborated: the first one was made with dried grapes; Vitis vinifera L. Garnacha Tintorera has excellent potential to produce wines from raisined grapes; the second one, a fortified sweet wine aged in oak barrels. Different red Garnacha Tintorera-based wines (a dry base wine, GBW; a naturally sweet wine, GNSW; and a fortified sweet wine, GFSW) were characterized. Chromatic characteristics and phenolic compounds were established by spectrophotometric methods in order to assess the technology of Garnacha Tintorera-based sweet wines. High molecular weight brown polymers, produced during the grape drying process and isolated from sweet wines by the dialysis process, were responsible for the brown colour of sweet wines. As a consequence, yellowness of sweet wines was also higher which was confirmed by colorimetric indexes. With respect to phenolic content, GFSW presented the lowest content because the maceration-alcoholic fermentation was stopped through the addition of alcohol before the diffusion of red pigments from skins to must was complete. GNSW presented the highest phenolic content due to the concentration effect resulting from evaporation of water from the grapes. Anthocyanins of sweet wines were polymerised in great extent.

    Full Text Available We present the first case of small cell lung cancer with Lambert-Eaton myasthenic syndrome during hemodialysis (HD. A 72-year-old male patient receiving HD experienced progressive muscle weakness. He was diagnosed with small cell lung cancer with Lambert-Eaton myasthenic syndrome due to an increased serum level of anti-voltage-gated calcium channel antibody and aspiration cytology on endobronchial ultrasonography for the swelling of a subcarinal lymph node. He received chemotherapy consisting of carboplatin (300 mg/m2 and etoposide (50 mg/m2, to which he had a partial response. However, the second therapy course could not be administered because of the unexpected development of severe hematological adverse events, which also prevented him from undergoing further HD. This case indicates that caution should be taken when using chemotherapy for such patients because of hypotension due to chemotherapy, with which it is impossible to undergo HD.

    Full Text Available Ectopic ACTH-syndrome is the most diagnostically challenging  variant of endogenous hypercortisolism. Particularly difficult differential diagnosis of this syndrome is from Cushing's disease (CD, as currently there is no single test sufficiently accurate to differentiate accurately ectopic ACTH production from the pituitary. The main functional tests are based on the fact that the vast majority of ectopic ACTH production is autonomous and suppresses one from pituitary. But in some cases this is not observed, and then the data obtained all necessary laboratory and instrumental research evidence in favor of central genesis of CD in a patient with ACTH ectopic secretion, which can lead to inappropriate treatment. If you confirm the ectopic ACTH-syndrome, it may take quite a long time of searching for the pathological focus, as there is no sufficiently precise imaging and diagnostic method for determining the localization of ectopic source of ACTH production. Thus, the differential diagnosis of ACTH-dependent hypercortisolism and localization of the ectopic tumor is the cornerstone of early and radical treatment of patients. We present a difficult clinical case of a patient having a pituitary hyperplasia with excessive ACTH expression with primary ectopic ACTH syndrome caused by lung carcinoid.

    We hypothesized a sweet potato intervention would prevent high-fat (HF) diet-induced aortic stiffness, which would be associated with decreased arterial oxidative stress and increased mitochondrial uncoupling. Young (8-week old) C57BL/6J mice were randomly divided into 4 groups: low fat (LF; 10% fat), HF (60% fat), low-fat sweet potato (LFSP; 10% fat containing 260.3 μg/kcal sweet potato), or high-fat sweet potato diet (HFSP; 60% fat containing 260.3 μg/kcal sweet potato) for 16 weeks. Compared with LF and LFSP, HF- and HFSP-fed mice had increased body mass and percent fat mass with lower percent lean mass (all, P Sweet potato intervention did not influence body composition (all, P > 0.05). Arterial stiffness, assessed by aortic pulse wave velocity and ex vivo mechanical testing of the elastin region elastic modulus (EEM) was greater in HF compared with LF and HFSP animals (all, P sweet potato attenuates diet-induced aortic stiffness independent of body mass and composition, which is associated with a normalization of arterial oxidative stress possibly due to mitochondrial uncoupling.

    The Child Tourette Syndrome Impairment Scale (CTIM) rates 37 problems in school, social, and home domains separately for tics and for comorbid diagnoses. However, a shorter version would be easier to implement in busy clinics. Using published data from 85 children with Tourette syndrome, 92 controls, and parents, factor analysis was used to generate a "mini-CTIM" composed of 12 items applied to tic and comorbid diagnoses. Child- and parent-rated mini-CTIM scores were compared and correlated across raters and accounting for clinician-rated tic severity and presence of attention-deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). The mini-CTIM achieved domain Cronbach alphas ranging from 0.71 to 0.94 and intra-item correlation coefficients ranging from 0.84 to 0.96. The resulting scale correlated with clinician-rated tic severity and reflected the presence of ADHD and OCD. The mini-CTIM appears promising as a practical assessment tool for tic- and non-tic-related impairment in children with Tourette syndrome.

    Full Text Available Marfan syndrome (MFS, the founding member of connective tissue disorder, is an autosomal dominant disease; it is caused by a deficiency of the microfibrillar protein fibrillin-1 (FBN1 and characterized by involvement of three main systems; skeletal, ocular, and cardiovascular. More than one thousand mutations in FBN1 gene on chromosome 15 were found to cause MFS. Nephrotic syndrome (NS had been described in very few patients with MFS being attributed to membranoproliferative glomerulonephritis secondary to infective endocarditis. Focal segmental glomerulosclerosis (FSGS had been reported in NS in conjunction with MFS without confirming the diagnosis by mutational analysis of FBN1. We hereby present an Egyptian family with MFS documented at the molecular level; it showed a male proband with NS secondary to FSGS, unfortunately, we failed to make any causal link between FBN dysfunction and FSGS. In this context, we review the spectrum of renal involvements occurring in MFS patients.

    Cholesterol side-chain cleavage enzyme (P450scc) deficiency is a rare genetic disorder causing primary adrenal insufficiency with or without a 46,XY disorder of sexual development (DSD). Herein, we report a case of the combination of primary adrenal insufficiency, a DSD (testes with female external genitalia in a setting of a 47,XXY karyotype), and Angelman syndrome. Comprehensive genetic analyses were performed, including a single nucleotide polymorphism microarray and whole-exome sequencing. In vitro studies were performed to evaluate the pathogenicity of the novel mutation that was identified by whole-exome sequencing. The patient was found to have segmental uniparental disomy (UPD) of chromosome 15 explaining her diagnosis of Angelman syndrome. Whole-exome sequencing further revealed a novel homozygous intronic variant in CYP11A1, the gene encoding P450scc, found within the region of UPD. In vitro studies confirmed that this variant led to decreased efficiency of CYP11A1 splicing. We report the first case of the combination of 2 rare genetic disorders, Angelman syndrome, and P450scc deficiency. After 20 years of diagnostic efforts, significant advances in genetic diagnostic technology allowed us to determine that these 2 disorders originate from a unified genetic etiology, segmental UPD unmasking a novel recessive mutation in CYP11A1. © 2018 S.

    The Nance-Horan syndrome is an X-linked disorder characterized by congenital cataract, facial features, microcornea, microphthalmia, and dental anomalies; most of the cases are due to NHS gene mutations on Xp22.13. Heterozygous carrier females generally present less severe features, and up to 30% of the affected males have intellectual disability. We describe two patients, mother and daughter, manifesting Nance-Horan syndrome. The cytogenetic and molecular analyses demonstrated a 46,X,t(X;1)(p22.13;q22) karyotype in each of them. No copy-number genomic imbalances were detected by high-density microarray analysis. The mother had a preferential inactivation of the normal X chromosome; expression analysis did not detect any mRNA isoform of NHS. This is the first report of Nance-Horan syndrome due to a skewed X chromosome inactivation resulting from a balanced translocation t(X;1) that disrupts the NHS gene expression, with important implications for clinical presentation and genetic counseling.

    Community-acquired methicillin-resistant Staphylococcus aureus has been spreading worldwide, including in Japan. However, few cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus have been reported in Japan. We report 2 cases, in middle-aged women, of toxic shock syndrome due to Community-acquired methicillin-resistant Staphylococcus aureus via a vaginal portal of entry. The first patient had used a tampon and the second patient had vaginitis due to a cleft narrowing associated with vulvar lichen sclerosus. Both patients were admitted to our hospital with septic shock and severe acute kidney injury and subsequently recovered with appropriate antibiotic treatment. In our review of the literature, 8 cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus were reported in Japan. In these 8 cases, the main portals of entry were the skin and respiratory tract; however, the portal of entry of Community-acquired methicillin-resistant Staphylococcus aureus from a vaginal lesion has not been reported in Japan previously.

    Full Text Available The aim of the conducted study was to determine to what extent the cultivation of sweet pepper lowers the phytotoxicity of a substrate. The examined material was a highly phytotoxic substrate due to repeated cucumber growing on it. This substrate was a mixture of pine and beech bark, low peat and sawdust. Five sweet pepper cultivars: Amador, Bell Boy, Culinar, Poznańska Słodka and WSE 2/82 were planted. During vegetation of the sweet pepper phytotoxicity and phenolics levels were determined in the substrate. It was found that cultivation of sweet pepper had a significant effect on lowering phytotoxicity and phenolics content in the substrate. Among the five tested cultivars, the highest detoxicating ability was exhibited by Amador, Culinar and WSE 2/82 while the Poznańska Słodka did not show such abilities.

    Full Text Available Introduction Sweet corn is the one of the most important types of corn. There is a high amount of sugar in the endosperm of sweet corn than dent corn. Baby corn is the ear of corn that is being harvested in the silking stage before the end of pollination. This crop has an interesting using methods as salad, conserve production and vegetative consumption. Both two sweet and baby corn is obtained from one plant in different growth stages and could be harvested from one corn hybrid. Best yield and quality of baby corn is obtained from sweet corn hybrids, because of high amounts of sugar in the grains and ears. Sweet corn and baby corn could be harvested at early dough stage (with about 30 % of humidity and early silking stage before the pollination is completed, respectively. Plant density is the most important factor in growing corn, especially in sweet and baby corn. Khuzestan province is one of the main regions of corn production in Iran. In Khuzestan, forage and silage corn have the most production among the summer crops. Corn is planted in two planting date in Khuzestan: early spring and early summer. Spring corn planting produces little grain yield due to Simultaneity of silking stage with hot early summer days. Because of little production and little research about sweet and baby corn, this study was performed and designed. Materials and Methods In order to investigate the effects of plant density and harvesting method on sweet corn and baby corn yield, an experiment was performed during 2012-13, in research farm of Ramin Agriculture and Natural Resources University of Khuzestan, located in southwest of Iran. In this experiment, four plant densities (7, 9, 11 and 13 plants.m-2 and two harvesting methods (baby corn and sweet corn were investigated in an RCB statistical design with four replications.

    People with carpal tunnel syndrome (CTS) exhibit widespread pressure pain and thermal pain hypersensitivity as a manifestation of central sensitization. The aim of our study was to compare the effectiveness of manual therapy versus surgery for improving pain and nociceptive gain processing in people with CTS. The trial was conducted at a local regional Hospital in Madrid, Spain from August 2014 to February 2015. In this randomized parallel-group, blinded, clinical trial, 100 women with CTS were randomly allocated to either manual therapy (n = 50), who received three sessions (once/week) of manual therapies including desensitization manoeuvres of the central nervous system, or surgical intervention (n = 50) group. Outcomes including pressure pain thresholds (PPT), thermal pain thresholds (HPT or CPT), and pain intensity which were assessed at baseline, and 3, 6, 9 and 12 months after the intervention by an assessor unaware of group assignment. Analysis was by intention to treat with mixed ANCOVAs adjusted for baseline scores. At 12 months, 95 women completed the follow-up. Patients receiving manual therapy exhibited higher increases in PPT over the carpal tunnel at 3, 6 and 9 months (all, p < 0.01) and higher decrease of pain intensity at 3 month follow-up (p < 0.001) than those receiving surgery. No significant differences were observed between groups for the remaining outcomes. Manual therapy and surgery have similar effects on decreasing widespread pressure pain sensitivity and pain intensity in women with CTS. Neither manual therapy nor surgery resulted in changes in thermal pain sensitivity. The current study found that manual therapy and surgery exhibited similar effects on decreasing widespread pressure pain sensitivity and pain intensity in women with carpal tunnel syndrome at medium- and long-term follow-ups investigating changes in nociceptive gain processing after treatment in carpal tunnel syndrome. © 2017 European Pain Federation - EFIC®.

  2. Dental phenotype in Jalili syndrome due to a c.1312 dupC homozygous mutation in the CNNM4 gene.

    Directory of Open Access Journals (Sweden)

    Hans U Luder

    Full Text Available Jalili syndrome denotes a recessively inherited combination of an eye disease (cone-rod dystrophy and a dental disorder (amelogenesis imperfecta, which is caused by mutations in the CNNM4 gene. Whereas the ophthalmic consequences of these mutations have been studied comprehensively, the dental phenotype has obtained less attention. A defective transport of magnesium ions by the photoreceptors of the retina is assumed to account for the progressive visual impairment. Since magnesium is also incorporated in the mineral of dental hard tissues, we hypothesized that magnesium concentrations in defective enamel resulting from mutations in CNNM4 would be abnormal, if a similar deficiency of magnesium transport also accounted for the amelogenesis imperfecta. Thus, a detailed analysis of the dental hard tissues was performed in two boys of Kosovan origin affected by Jalili syndrome. Retinal dystrophy of the patients was diagnosed by a comprehensive eye examination and full-field electroretinography. A mutational analysis revealed a c.1312 dupC homozygous mutation in CNNM4, a genetic defect which had already been identified in other Kosovan families and putatively results in loss-of-function of the protein. The evaluation of six primary teeth using light and scanning electron microscopy as well as energy-dispersive X-ray spectroscopy showed that dental enamel was thin and deficient in mineral, suggesting a hypoplastic/hypomineralized type of amelogenesis imperfecta. The reduced mineral density of enamel was accompanied by decreased amounts of calcium, but significantly elevated levels of magnesium. In dentin, however, a similar mineral deficiency was associated with reduced magnesium and normal calcium levels. It is concluded that the c.1312 dupC mutation of CNNM4 results in mineralization defects of both enamel and dentin, which are associated with significantly abnormal magnesium concentrations. Thus, we could not disprove the hypothesis that a

    This article is the first in a series presenting the strongest published evidence for physical and rehabilitation medicine (PRM) to date coming from the Cochrane Collaboration. The intent of the series is to stimulate ideas for reviews and research in neglected areas of PRM. To systematically review the rehabilitation contents of the Cochrane Collaboration on disabilities due to spinal disorders or pain syndromes in adults. The Cochrane Database of Systematic Reviews was searched at the end of June 2013 for articles relevant for PRM about disabilities resulting from spinal disorders or pain syndromes in adults. Retrieved papers were classified according to the PRM approach: active therapies, which require active participation by patients to achieve treatment goals, and passive treatments, which rely on the application of external forces. The quality of the reviews was checked against the AMSTAR checklist. Reviews on spinal disorders or pain syndromes were found in the Cochrane Back Group (CBG) and in the Pain, Palliative and Supportive Care Group (CPPSCG). Thirty-eight (42.8%) of 89 Cochrane reviews in the CBG and 7 (2.4%) of 293 Cochrane reviews in the CPPSCG were included. All were of high quality (range, 8-11 points out of 11 on the AMSTAR checklist). The contents of the reviews are given in detail. This review presents an overview of the current evidence for PRM in the treatment of disabilities due to spinal disorders or pain syndromes in adults. Within PRM there is ample space for research in the Cochrane Collaboration and for producing original studies (randomized controlled trials [RCTs]). To apply evidence-based clinical practice, clinicians must be familiar with the current best evidence.

    Full Text Available Nasal polyps are inflammatory proliferative tumors arising from the mucosa of the nasal cavity and paranasal sinuses. Although many cases concerning nasal polyps have been reported, those involving external nasal deformities are rare. We report a case of nasal polyposis filling the nasal cavity and paranasal sinuses, leading to external nasal and facial deformities. The condition above is known as Woakes’ syndrome, which is characterized by severe recurrent nasal polyps with deformity of the nasal pyramid, leading to broadening of the nose. We performed nasal osteotomy and facial bone-shaving via the midface degloving approach, which improved the patient’s facial appearance.

Case presentation A 32-year old manual laborer man presented with a two-year history of numbness, tingling and burning pain in the palmar surface of the left hand and fingers. His medical history was unremarkable and no trauma episode was reported. According to the clinical examination and the result of median nerve conduction study (NCS the diagnosis of carpal tunnel syndrome was established. Operative release of the transverse carpal ligament was subsequently performed but the patient experienced only temporary relief of his symptoms. MRI examination revealed a deep palmary located mass with well-defined margins and ovoid shape. Intraoperatively, the tumor was in continuity with the flexor digitorum superficialis tendon of the middle finger causing substantial compression to median nerve. Histopathological findings of the resected mass were consistent with leiomyoma. After two years the patient was pain-free without signs of tumor recurrence. Conclusion Despite the fact that reports on deep soft tissue leiomyoma are exceptional, this tumor had to be considered as differential diagnosis in painful non-traumatic hand syndromes especially in young patients.

    Full Text Available The use of conventional cytogenetic techniques in combination with fluorescent in situ hybridization (FISH and single-nucleotide polymorphism (SNP microarrays is necessary for the identification of cryptic rearrangements in the diagnosis of chromosomal syndromes. We report two siblings, a boy of 9 years and 9 months of age and his 7-years- and 5-month-old sister, with the classic Wolf-Hirschhorn syndrome (WHS phenotype. Using high-resolution GTG- and NOR-banding karyotypes, as well as FISH analysis, we characterized a pure 4p deletion in both sibs and a balanced rearrangement in their father, consisting in an insertion of 4p material within a nucleolar organizing region of chromosome 15. Copy number variant (CNV analysis using SNP arrays showed that both siblings have a similar size of 4p deletion (~6.5 Mb. Our results strongly support the need for conventional cytogenetic and FISH analysis, as well as high-density microarray mapping for the optimal characterization of the genetic imbalance in patients with WHS; parents must always be studied for recognizing cryptic balanced chromosomal rearrangements for an adequate genetic counseling.

    2017-09-01

    Full Text Available Stroke is generally considered to be the first preliminary diagnosis in patients presenting with acute hemiparesia in the emergency department. But rarely in unexpected spontaneous neurological pathologies that may lead to hemiparesis. The data from 8 non-traumatic patients who underwent surgical treatment for brown-sequard syndrome (BSS were reviewed retrospectively. All patients were initially misdiagnosed with strokes. Two of the patients had spinal canal stenosis, two had spinal epidural hematomas, one had an ossified herniated disc and three had soft herniated discs. None of the patients complained of significant pain at the initial presentation. All of the patients had a mild sensory deficit that was initially unrecognized. The pain of the patients began to become evident after hospitalization and, patients transferred to neurosurgery department. Cervical spinal pathologies compressing the corticospinal tract in one-half of the cervical spinal canal may present with only hemiparesis, without neck and radicular pain. If it's too late, permanent neurological damage may become inevitable while it is a correctable pathology.

    For 30 years, Phelan and co-workers described a syndrome characterised by neonatal hypotonia, global developmental delay, strongly impaired speech, sleep disturbances and hyperreactivity to sensory stimuli. This Phelan-McDermid syndrome (PMS), also presenting with symptoms from the autism spectrum and a higher risk of developing seizure disorders, may be caused by a deletion of chromosome 22q13 or by a mutation in the SHANK3 gene. Its core psychopathological phenotype comprises symptoms from the bipolar spectrum for which generally treatment with a mood-stabilising anticonvulsant in combination with an atypical antipsychotic seems to be most effective. In addition to two elsewhere published adolescent patients, we here describe in detail the history of an adult male patient with PMS caused by a SHANK3 mutation in whom successive treatment regimens with antipsychotics and mood-stabilising anticonvulsants were all ineffective. Ultimately, addition of lithium to existing olanzapine therapy led to enduring stabilisation of mood and behaviour. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Beckwith-Wiedemann syndrome (BWS) is caused by dysregulation of imprinted genes on chromosome 11.p15.5. The syndrome includes overgrowth, macroglossia, organomegaly, abdominal wall defects, hypoglycemia, and long-term malignancy risk. No patient who has BWS has been reported with hypopituitarism. We describe a patient who presented at birth with macrosomia, macroglossia, respiratory distress, jaundice, and hypoglycemia, and who was followed for 4.5 years. Genetic test for BWS was performed, which detected loss of maternal methylation on region KvDMR1 (11p15.5). The hypoglycemia was attributable to hyperinsulinism and was treated with diazoxide and chlorothiazide. She responded well, but the hypoglycemia returned after reducing the diazoxide. It was possible to stop the diazoxide after 2.5 years. On routine follow-up she was noted to be developing short stature. Baseline pituitary and growth hormone (GH) stimulation tests detected GH deficiency and secondary hypothyroidism. A brain MRI showed a small anterior pituitary gland. Thereafter, thyroxine and replacement therapy with GH were started, which resulted in a remarkable improvement in growth velocity. This is the first patient to be reported as having hypopituitarism and BWS. It is unclear if the BWS and the hypopituitarism are somehow connected; however, further investigations are necessary. Hypopituitarism explains the protracted hypoglycemia and the short stature. In our patient, GH therapy seems to be safe, but strict follow-up is required given the increased cancer risk related to BWS.

    Breast cancer-related lymphedema often causes cellulitis and is one of the most common complications after breast cancer surgery. Streptococci are the major pathogens underlying such cellulitis. Among the streptococci, the importance of the Lancefield groups C and G is underappreciated; most cases involve Streptococcus dysgalactiae subspecies equisimilis. Despite having a relatively weak toxicity compared with group A streptococci, Streptococcus dysgalactiae subspecies equisimilis is associated with a mortality rate that is as high as that of group A streptococci in cases of invasive infection because Streptococcus dysgalactiae subspecies equisimilis mainly affects elderly individuals who already have various comorbidities. An 83-year-old Japanese woman with breast cancer-related lymphedema in her left upper limb was referred to our hospital with high fever and acute pain with erythema in her left arm. She showed septic shock with disseminated intravascular coagulation. Blood culture showed positive results for Streptococcus dysgalactiae subspecies equisimilis, confirming a diagnosis of streptococcal toxic-shock syndrome. She survived after successful intensive care. To the best of our knowledge, this case represents the first report of Streptococcus dysgalactiae subspecies equisimilis-induced streptococcal toxic-shock syndrome in a patient with breast cancer-related lymphedema. Breast cancer-related lymphedema is a common problem, and we must pay attention to invasive streptococcal soft tissue infections, particularly in elderly patients with chronic disease.

    Field sweet potato plants showing virus-like symptoms, as stunting, leaf distortion, mosaic and chlorosis, were collected in southwest Portugal and tested for the presence of four potyviruses, sweet potato virus C (SPVC), sweet potato virus 2 (SPV2), sweet potato feathery mottle virus (SPFMV), sweet potato virus G (SPVG), and the crinivirus sweet potato chlorotic stunt virus (SPCSV). DsRNA fractions were extracted from symptomatic leaves and used as templates in single and multiplex RT-PCR assays using previously described specific primers for each analyzed virus. The amplified reaction products for SPVC, SPV2 and SPFMV were of expected size, and direct sequencing of PCR products revealed that they correspond to the coat protein gene (CP) and showed 98%, 99% and 99% identity, respectively, to those viruses. Comparison of the CP genomic and amino acid sequences of the Portuguese viral isolates recovered here with those of ten other sequences of isolates obtained in different countries retrieved from the GenBank showed very few differences. The application of the RT-PCR assays revealed for the first time the presence of SPVC and SPFMV in the sweet potato crop in Portugal, the absence of SPVG and SPCSV in tested plants, as well as the occurrence of triple virus infections under field conditions.

    Rhabdoid tumors are aggressive malignancies that show loss-of-function mutations of SMARCB1 gene, a member of the SWI/SNF chromatin-remodeling complex controlling gene transcription. One-third of patients affected by rhabdoid tumor harbor a germ-line mutation of SMARCB1 defining a rhabdoid tumor predisposition syndrome. The occurrence of a second somatic mutation determines the development of neoplasia in a two-hit model. Most germ-line mutations occur de novo, and few cases of recurrence in a sibship have been described. Here we report on a new Italian family with recurrence of SMARCB1 germ-line deletion in two siblings due to gonadal mosaicism. The deletion was identified in the 9-month-old proband with malignant rhabdoid tumor of the right kidney and disseminated metastases. Testing of both parents confirmed the de novo origin of the mutation, but recurrence was then detected prenatally in a new pregnancy. This is the sixth family with malignant rhabdoid tumor predisposition syndrome with the recurrence of the same germ-line SMARCB1 mutation in the sibship but not in healthy parents, suggesting that gonadal mosaicism is a less rare event than supposed. The clinical outcome in our patient confirms previous data of poorer outcome in patients with rhabdoid tumor predisposition syndrome.

    This report describes a 66-year-old Caucasian male who acutely developed severe, bilateral impairment of visual acuity at 24 years of age. Leber's hereditary optic neuropathy (LHON) was suspected but the diagnosis was not genetically confirmed until the age of 49 years when the primary LHON mutation m.3460G>A was detected. Since onset, visual acuity had slightly improved. The family history was positive for LHON (brother, two sisters of mother, female cousin) and genetically confirmed in his brother and one aunt. Since the age of 65 years, he had experienced recurrent vertigo. His cardiological history was positive for arterial hypertension, noncompaction, myocardial thickening, intermittent right bundle-branch-block (RBBB) and Wolff-Parkinson-White (WPW) syndrome. In addition to LHON, he presented with polyneuropathy, hyperCKaemia, carotid artery occlusion, and a history of stroke. Cardiological investigations at 66 years of age revealed mildly reduced systolic function, enlarged atria, and nonsustained ventricular tachycardias. He underwent an electrophysiological investigation, but radiofrequency ablation was ruled out due to a 'bizarre' cardiac conduction system. Instead, an implantable cardioverter defibrillator was proposed but refused by the patient. Since the vertigo did not resolve it was attributed to polyneuropathy. This case demonstrates that LHON may be associated with noncompaction, myocardial thickening, reduced systolic function, enlarged atria, RBBB, WPW syndrome and nonsustained ventricular tachycardias. WPW syndrome in LHON may require invasive antiarrhythmic treatment.

    Williams-Beuren syndrome (WBS) is a relatively common, clinically recognizable microdeletion syndrome. In most cases the typical heterozygous deletion of 1.5 Mb on chromosome 7q11.23 spanning about 26 genes can be identified. Also some larger or smaller atypical deletions have been reported and associated with additional or atypical phenotypic aspects. We report on an individual with typical WBS due to the common deletion and with refractory infantile spasms. Using trio-exome sequencing, we identified a de novo truncating variant c.1200del, p (Lys401Serfs*25) in GABRA1 as the likely cause of the early onset epilepsy. This unique case not only allows to further define the phenotypic spectrum of infantile epileptic encephalopathy associated with rare de novo GABRA1 variants but exemplifies the need for a sensitive review of unclear associations in clinically defined syndromes and for extended diagnostic work-up in individuals with unusual presentations of a genetically confirmed diagnosis.

    To present a rare anomaly consisting of uterus didelphys, longitudinal vaginal septum, obstructed hemivagina with pyocolpos, fistula to the open vaginal canal, and ipsilateral renal agenesis, referred as Herlyn-Werner-Wunderlich syndrome (HWWS). A 14-year-old girl with recurring purulent vaginal discharge lasting for a few months. Preoperative examination revealed one vaginal canal with one cervical opening on the right side. There was a fistula leading from the obstructed vaginal canal to the left vagina. Intravaginal ultrasound examination demonstrated a longitudinal vaginal septum and a closed pyocolpos on the right side. The longitudinal vaginal septum was excised by way of electrocauterization under direct vision. HWWS should be considered in the differential diagnosis in patients with uterus didelphys and unusual symptoms such as pyocolpos and vaginal discharge.

    We herein report a 31-year-old Japanese woman with evolving hypopituitarism due to pituitary stalk transection syndrome. She had a history of short stature treated with growth hormone (GH) in childhood and had hypothyroidism and primary amenorrhea at 20 years old. Levothyroxine replacement and recombinant follicle stimulating hormone-human chorionic gonadotropin (FSH-hCG) therapy for ovulation induction were started. GH replacement therapy (GHRT) was resumed when she was 26 years old. She developed mild adrenocortical insufficiency at 31 years old. She succeeded in becoming pregnant and delivered twice. GHRT was partially continued during pregnancy and stopped at the end of the second trimester without any complications. PMID:28250299

    Biochemical changes associated with obesity may accelerate osteoarthritis beyond the effect of mechanical factors. This study investigated whether metabolic syndrome and its components (visceral obesity, hypertension, dyslipidemia and insulin resistance) were risk factors for subsequent total hip replacement (THR) or total knee replacement (TKR) due to primary osteoarthritis. In this prospective cohort study, data from the second survey of the Nord-Trøndelag Health Study 2 (HUNT2) were linked to the Norwegian Arthroplasty Register for identification of the outcome of THR or TKR. The analyses were stratified by age (<50, 50-69.9 and ≥70 years) and adjusted for gender, body mass index, smoking, physical activity and education. Of the 62,661 participants, 12,593 (20.1%) were identified as having metabolic syndrome, and we recorded 1,840 (2.9%) THRs and 1,111 (1.8%) TKRs during a mean follow-up time of 15.4 years. Cox regression analyses did not show any association between full metabolic syndrome and THR or TKR, except in persons <50 years with metabolic syndrome who had a decreased risk of THR (hazard ratio [HR] 0.58, 95% CI 0.40-0.83). However, when including only participants whose exposure status did not change during follow-up, this protective association was no longer significant. Increased waist circumference was associated with increased risk of TKR in participants <50 years (HR 1.62, 95% CI 1.10-2.39) and 50-69.9 years (HR 1.43, 95% CI 1.14-1.80). Hypertension significantly increased the risk of TKR in participants <50 years (HR 1.38, 95% CI 1.05-1.81), and this risk was greater for men. This study found an increased risk of TKR in men <50 years with hypertension and persons <70 years with increased waist circumference. Apart from this, neither metabolic syndrome nor its components were associated with increased risk of THR or TKR due to primary osteoarthritis.

  3. Bitter and sweet tasting molecules: It's complicated.

    "Bitter" and "sweet" are frequently framed in opposition, both functionally and metaphorically, in regard to affective responses, emotion, and nutrition. This oppositional relationship is complicated by the fact that some molecules are simultaneously bitter and sweet. In some cases, a small chemical modification, or a chirality switch, flips the taste from sweet to bitter. Molecules humans describe as bitter are recognized by a 25-member subfamily of class A G-protein coupled receptors (GPCRs) known as TAS2Rs. Molecules humans describe as sweet are recognized by a TAS1R2/TAS1R3 heterodimer of class C GPCRs. Here we characterize the chemical space of bitter and sweet molecules: the majority of bitter compounds show higher hydrophobicity compared to sweet compounds, while sweet molecules have a wider range of sizes. Importantly, recent evidence indicates that TAS1Rs and TAS2Rs are not limited to the oral cavity; moreover, some bitterants are pharmacologically promiscuous, with the hERG potassium channel, cytochrome P450 enzymes, and carbonic anhydrases as common off-targets. Further focus on polypharmacology may unravel new physiological roles for tastant molecules. Copyright © 2018 Elsevier B.V. All rights reserved.

    Lodging is a serious problem in plant growth, especially in crops growth of the natural habitat. In order to determine the influence of lodging on the growth characters of sweet sorghum, plants grown in natural saline-alkali environment were used to investigate the fresh weight, dry weight, sugar content in the stalks and the photosynthesis index of salt tolerant crop sweet sorghum. Results showed that lodging significantly reduced the growth of sweet sorghum, the fresh weight and dry weight was only 28.3% and 22.5% of the normal plants when lodging occurred after 49 days. Lodging also reduced the stalks sugar content of sweet sorghum, the stalk sugar content of lodged plants was only 45.4% of that in the normal plants, when lodging occurred for 49 days. Lodging reduced the growth and sugar content by reducing the photosynthesis parameters of sweet sorghum grown in the saline-alkali field, thus, affected the accumulation of photosynthate. Interestingly, with the extension of the lodging time, lodging led to a decrease in photosynthetic rate of sweet sorghum mainly due to non-stomatal factors.

    Among the available transformation methods reported on sweet potato, Agrobacterium tumefaciens-mediated transformation is more successful and desirable. Stem explants have shown to be ideal for the transformation of sweet potato because of their ready availability as explants, the simple transformation process, and high-frequency-regeneration via somatic embryogenesis. Under the two-step kanamycin-hygromycin selection method and using the appropriate explants type (stem explants), the efficiency of transformation can be considerably improved in cv. Beniazuma. The high efficiency in the transformation of stem explants suggests that the transformation protocol described in this chapter warrants testing for routine stable transformation of diverse varieties of sweet potato.

    Full Text Available A 22-year-old male came to casualty on 5 th May 2012 after a fall from motorcycle. He complained of excruciating pain and swelling over right knee. There was an open wound of 7 × 2 cm over supra-patellar region and diffuse swelling over knee joint with severe tenderness over proximal aspect of right tibia. X-ray showed intra-articular fracture of proximal tibia extending to diaphysis classified as type 6 by Schatzker classification for proximal tibia, with fibula shaft transverse fracture. The skin over the fracture was contused. Debridement with primary wound closure was done in emergency. Skeletal traction was applied through a lower tibial Steinman pin. Patient was operated after 15 days when wound healed and swelling subsided. Locking plate was applied on medial aspect using Minimally invasive percutaneous plate osteosysthesis (MIPPO technique. Post-operatively over 4 hours patient developed severe pain and swelling in operated leg which mimicked compartment syndrome. Suture removal was done immediately in the ward from the distal aspect, which relieved the symptoms but lead to exposure of the plate. A rotational flap was done to cover the plate in coordination with a plastic surgeon on the next day.

    Beauty parlor stroke syndrome (BPSS) is a rare condition characterized by mechanical impingement of a vertebral artery (VA) during neck rotation and/or hyperextension followed by vertebrobasilar insufficiency. However, there have been no reports of BPSS in which the cause of mechanical impingement was identified and no cases for which surgical treatment was reported. The authors report the case of a 56-year-old Japanese man who presented with presyncope that occurred during cervical extension. Given the possibility of vertebrobasilar insufficiency, digital subtraction angiography and CT angiography were performed. These studies revealed that the right VA was hypoplastic and the left VA was dominant. Moreover, in the position of cervical extension, the dominant left VA showed constriction caused by a bone fragment of an osteophyte of the atlas. Removal of the bone fragment was performed. Postoperative left vertebral angiography showed improvement of blood flow in the extended position, and the presyncope completely disappeared. The pathomechanism of this case was a bone fragment compressing the left VA in the C-1 groove during neck extension. In BPSS patients with recurrent transient symptoms, the possibility of this mechanism of VA constriction by a free bone fragment should be considered.

    Brown-Vialetto-Van Laere syndrome (BVVLS [MIM 211530]) is a rare neurological disorder characterized by infancy onset sensorineural deafness and ponto-bulbar palsy. Mutations in SLC52A3 (formerly C20orf54), coding for riboflavin transporter 2 (hRFT2), have been identified as the molecular genetic correlate in several individuals with BVVLS. Exome sequencing of just one single case revealed that compound heterozygosity for two pathogenic mutations in the SLC52A2 gene coding for riboflavin transporter 3 (hRFT3), another member of the riboflavin transporter family, is also associated with BVVLS. Overexpression studies confirmed that the gene products of both mutant alleles have reduced riboflavin transport activities. While mutations in SLC52A3 cause decreased plasma riboflavin levels, concordant with a role of SLC52A3 in riboflavin uptake from food, the SLC52A2-mutant individual had normal plasma riboflavin concentrations, a finding in line with a postulated function of SLC52A2 in riboflavin uptake from blood into target cells. Our results contribute to the understanding of human riboflavin metabolism and underscore its role in the pathogenesis of BVVLS, thereby providing a rational basis for a high-dose riboflavin treatment.

    Uniparental disomy has recently been recognized to cause human disorders, including Prader-Willi syndrome (PWS). The authors describe a particularly instructive case which raises important issues concerning the mechanisms producing uniparental disomy and whose evaluation provides evidence that trisomy may precede uniparental disomy in a fetus. Chorionic villus sampling performed for advanced maternal age revealed trisomy 15 in all direct and cultured cells, though the fetus appeared normal. Chromosome analysis of amniocytes obtained at 15 wk was normal in over 100 cells studied. The child was hypotonic at birth, and high-resolution banding failed to reveal the deletion of 15q11-13, a deletion which is found in 50%-70% of patients with PWS. Over time, typical features of PWS developed. Molecular genetic analysis using probes for chromosome 15 revealed maternal disomy. Maternal nondisjunction with fertilization of a disomic egg by a normal sperm, followed by loss of the paternal 15, is a likely cause of confined placental mosaicism and uniparental disomy in this case of PWS, and advanced maternal age may be a predisposing factor. 38 refs., 3 figs., 2 tabs.

    Non-immune hydrops fetalis may find its origin within genetically determined lymphedema syndromes, caused by mutations in FOXC2 and SOX-18. We describe a newborn girl, diagnosed with non-immune hydrops fetalis at a gestational age of 30 weeks. Family history revealed the presence of an autosomal dominant late-onset form of lymphedema of the lower limbs in her father, associated with an aberrant implantation of the eyelashes in some individuals. The newborn, hydropic girl suffered from severe pulmonary lymphangiectasia, resulting in terminal respiratory failure at the age of 3 months. Genetic analysis in both the father and the newborn girl demonstrated a heterozygous FOXC2 mutation, i.e., c.939C>A, p.Tyr313X. Her two older sisters are currently asymptomatic and the parents decided not to test them for the FOXC2 mutation. Patients with a mutation in the FOXC2 transcription factor usually show lower limb lymphedema with onset at or after puberty, together with distichiasis. However, the eye manifestations can be very mild and easily overlooked. The association between FOXC2 mutation and neonatal hydrops resulting in terminal respiratory failure is not reported so far. Therefore, in sporadic patients diagnosed with non-immune hydrops fetalis, lymphangiogenic genes should be systematically screened for mutations. In addition, all cases of fetal edema must prompt a thorough analysis of the familial pedigree, in order to detect familial patterns and to facilitate adequate antenatal counseling.

    2017-02-01

    Passenger lymphocyte syndrome (PLS) often occurs after ABO-mismatched solid organ and/or bone marrow transplantation between a donor and recipient. Viable donor B-lymphocytes transferred during organ transplantation produce antibodies against recipient red cell antigens, leading to hemolysis. The incidence of PLS has been reported to be around 9% after renal transplantation. A previous report showed that rituximab (Rit) was useful for treatment of PLS in allogeneic stem cell transplantation, bowel transplant and severe cases of hemolysis. However, the effectiveness of Rit in preventing PLS after renal transplantation has not yet been evaluated. The participants in this study were 85 patients who had undergone ABO-mismatched renal transplantation from January 2005 to April 2013. Rit was administered to these patients before transplantation. None of the patients that received Rit treatment developed PLS. Thus administration of Rit before transplantation effectively controlled the production of antibodies by B-lymphocytes, which probably prevented the development of PLS. © 2016 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

    We experienced a 10-year-old boy who had anaphylaxis after eating rose-flavored soft-serve ice cream. The patient felt a sense of discomfort in his throat when eating apple, peach, loquat, Japanese pear, and kiwi fruit. Therefore, we measured specific IgE antibodies to allergen components by ImmunoCAP ISAC. Consequently, the patient gave positive results for all PR-10 proteins from birch, alder, hazel, apple, peach, peanut, hazelnut, and soybean, so we diagnosed him with Pollen Food Allergy Syndrome (PFAS) induced by cross reactivity with pollens of birch family and fruits of rose family. When we conducted the skin prick test as is for red rose syrup because of the belief that anaphylaxis was caused by the rose ingredient contained in rose-flavored soft-serve ice cream, the patient gave a strong positive result. However, the results were negative for rose essence and Food Red No. 2 contained. Subsequently, it was found that red rose syrup contained apple juice. Therefore, we conducted the prick-prick test for apple, and the patient was confirmed to be strongly positive to apple. We thus identified apple as the cause of anaphylaxis. Since there is no legal obligation of labeling specific raw materials when directly selling manufactured and processed food products to general consumers, it is possible for general consumers to mistakenly take them in without knowing the containment of allergic substances. It is believed that the labeling method should be improved in the future.

  13. Long-Term Effect of GPi-DBS in a Patient With Generalized Dystonia Due to GLUT1 Deficiency Syndrome

    Full Text Available Treatment outcomes from pallidal deep brain stimulation are highly heterogeneous reflecting the phenotypic and etiologic spectrum of dystonia. Treatment stratification to neurostimulation therapy primarily relies on the phenotypic motor presentation; however, etiology including genetic factors are increasingly recognized as modifiers of treatment outcomes. Here, we describe a 53 year-old female patient with a progressive generalized dystonia since age 25. The patient underwent deep brain stimulation of the globus pallidus internus (GPi-DBS at age 44. Since the clinical phenotype included mobile choreo-dystonic features, we expected favorable therapeutic outcome from GPi-DBS. Although mobile dystonia components were slightly improved in the long-term outcome from GPi-DBS the overall therapeutic response 9 years from implantation was limited when comparing “stimulation off” and “stimulation on” despite of proper electrode localization and sufficient stimulation programming. In order to further understand the reason for this limited motor symptom response, we aimed to clarify the etiology of generalized dystonia in this patient. Genetic testing identified a novel heterozygous pathogenic SLC2A1 mutation as cause of glucose transporter type 1 deficiency syndrome (GLUT1-DS. This case report presents the first outcome of GPi-DBS in a patient with GLUT1-DS, and suggests that genotype relations may increasingly complement phenotype-based therapy stratification of GPi-DBS in dystonia.

    2018-03-01

    The present study investigates the cerebral effects of chronic occupational stress and its possible reversibility. Forty-eight patients with occupational exhaustion syndrome (29 women) and 80 controls (47 women) underwent structural magnetic resonance imaging (MRI) and neuropsychological testing. Forty-four participants (25 patients, 19 controls) also completed a second MRI scan after 1-2 years. Only patients received cognitive therapy. The stressed group at intake had reduced thickness in the right prefrontal cortex (PFC) and left superior temporal gyrus (STG), enlarged amygdala volumes, and reduced caudate volumes. Except for the caudate volume, these abnormalities were more pronounced in females. They were all related to perceived stress, which was similar for both genders. Thickness of the PFC also correlated with an impaired ability to down-modulate negative emotions. Thinning of PFC and reduction of caudate volume normalized in the follow-up. The amygdala enlargement and the left STG thinning remained. Longitudinal changes were not detected among controls. Chronic occupational stress was associated with partially reversible structural abnormalities in key regions for stress processing. These changes were dynamically correlated with the degree of perceived stress, highlighting a possible causal link. They seem more pronounced in women, and could be a substrate for an increased cerebral vulnerability to stress-related psychiatric disorders. © The Author 2017. Published by Oxford University Press.

    2007-07-01

    Full Text Available Abstract Background Alterations to pulmonary surfactant composition have been encountered in the Acute Respiratory Distress Syndrome (ARDS. However, only few data are available regarding the time-course and duration of surfactant changes in ARDS patients, although this information may largely influence the optimum design of clinical trials addressing surfactant replacement therapy. We therefore examined the time-course of surfactant changes in 15 patients with direct ARDS (pneumonia, aspiration over the first 8 days after onset of mechanical ventilation. Methods Three consecutive bronchoalveolar lavages (BAL were performed shortly after intubation (T0, and four days (T1 and eight days (T2 after intubation. Fifteen healthy volunteers served as controls. Phospholipid-to-protein ratio in BAL fluids, phospholipid class profiles, phosphatidylcholine (PC molecular species, surfactant proteins (SP-A, -B, -C, -D, and relative content and surface tension properties of large surfactant aggregates (LA were assessed. Results At T0, a severe and highly significant reduction in SP-A, SP-B and SP-C, the LA fraction, PC and phosphatidylglycerol (PG percentages, and dipalmitoylation of PC (DPPC was encountered. Surface activity of the LA fraction was greatly impaired. Over time, significant improvements were encountered especially in view of LA content, DPPC, PG and SP-A, but minimum surface tension of LA was not fully restored (15 mN/m at T2. A highly significant correlation was observed between PaO2/FiO2 and minimum surface tension (r = -0.83; p Conclusion We concluded that a profound impairment of pulmonary surfactant composition and function occurs in the very early stage of the disease and only gradually resolves over time. These observations may explain why former surfactant replacement studies with a short treatment duration failed to improve outcome and may help to establish optimal composition and duration of surfactant administration in future

    To study transition zones from normal to abnormal retina in Usher syndrome IB (USH1B) caused by myosin 7A (MYO7A) mutations. Optical coherence tomography (OCT) scattering layers in outer retina were segmented in patients (n = 16, ages 2-42; eight patients had serial data, average interval 4.5 years) to quantify outer nuclear layer (ONL) and outer segments (OS) as well as the locus of EZ (ellipsoid zone) edge and its extent from the fovea. Static perimetry was measured under dark-adapted (DA) and light-adapted (LA) conditions. Ellipsoid zone edge in USH1B-MYO7A could be located up to 23° from the fovea. Ellipsoid zone extent constricted at a rate of 0.51°/year with slower rates at smaller eccentricities. A well-defined EZ line could be associated with normal or abnormal ONL and/or OS thickness; detectable ONL extended well beyond EZ edge. At the EZ edge, the local slope of LA sensitivity loss was 2.6 (±1.7) dB/deg for central transition zones. At greater eccentricities, the local slope of cone sensitivity loss was shallower (1.1 ± 0.4 dB/deg for LA) than that of rod sensitivity loss (2.8 ± 1.2 dB/deg for DA). In USH1B-MYO7A, constriction rate of EZ extent depends on the initial eccentricity of the transition. Ellipsoid zone edges in the macula correspond to large local changes in cone vision, but extramacular EZ edges show more pronounced losses on rod-based vision tests. It is advisable to use not only the EZ line but also other structural and functional parameters for estimating natural history of disease and possible therapeutic effects in future clinical trials of USH1B-MYO7A.

    Full Text Available Abstract Background The aim of this study was to investigate the characteristics and outcomes of patients receiving renal replacement therapy for end-stage kidney disease (ESKD secondary to haemolytic uraemic syndrome (HUS. Methods The study included all patients with ESKD who commenced renal replacement therapy in Australia and New Zealand between 15/5/1963 and 31/12/2010, using data from the ANZDATA Registry. HUS ESKD patients were compared with matched controls with an alternative primary renal disease using propensity scores based on age, gender and treatment era. Results Of the 58422 patients included in the study, 241 (0.4% had ESKD secondary to HUS. HUS ESKD was independently associated with younger age, female gender and European race. Compared with matched controls, HUS ESKD was not associated with mortality on renal replacement therapy (adjusted hazard ratio [HR] 1.14, 95% CI 0.87-1.50, p = 0.34 or dialysis (HR 1.34, 95% CI 0.93-1.93, p = 0.12, but did independently predict recovery of renal function (HR 54.01, 95% CI 1.45-11.1, p = 0.008. 130 (54% HUS patients received 166 renal allografts. Overall renal allograft survival rates were significantly lower for patients with HUS ESKD at 1 year (73% vs 91%, 5 years (62% vs 85% and 10 years (49% vs 73%. HUS ESKD was an independent predictor of renal allograft failure (HR 2.59, 95% CI 1.70-3.95, p  Conclusions HUS is an uncommon cause of ESKD, which is associated with comparable patient survival on dialysis, an increased probability of renal function recovery, comparable patient survival post-renal transplant and a heightened risk of renal transplant graft failure compared with matched ESKD controls.

    Full Text Available Degradation of acetamiprid in sweet cherry samples was evaluated at several intervals from the product application until the end of the pre-harvest interval. An orchard of sweet cherries located at Stepanovićevo village near Novi Sad was used in this study. Acetamiprid was applied according to the manufacturer’s recommendation for protecting sweet cherries from their most important pests. Sweet cherry fruit samples were collected at eight intervals: immediately after acetamiprid application and 2, 4, 6, 8, 10, 12 and 14 days after application. The extraction of acetamiprid from sweet cherry samples was performed using a QuEChERS-based method. Determination was carried out using an HPLC-UV diode array detection system (Agilent 1100, United States with an Agilent Zorbax Eclipse C18 column (50 mm × 4.6 mm internal diameter, 1.8 μm particle size. The method was subjected to a thorough validation procedure. The recovery data were obtained by spiking blank sweet cherry samples at three concentration levels (0.1-0.3 mg/ kg, yielding 85.4% average recovery. Precision values expressed as relative standard deviation (RSD were below 1.61% for the intraday precision. Acetamiprid showed linear calibrations from 0.05 to 2.5 μg/ml with correlation coefficient (R2 of 0.995%. The limit of detection and limit of quantification were found to be 5 μg/kg and 14 μg/kg, respectively. The validated method was applied in the analysis of acetamiprid in sweet cherry samples. During the study period, the concentration of acetamiprid decreased from 0.529 mg/kg to 0.111 mg/kg. The content of acetamiprid in sweet cherry samples at the end of the pre-harvest interval was below the maximum permissible level specified by the Serbian and EU MRLs.

    Sweet potato (Ipomoea batatas) is ranked seventh in global food crop production and is the third most important root crop after potato and cassava. Sweet potatoes are vegetative propagated from vines, root slips (sprouts), or tubers. Therefore, virus diseases can be a major constrain, reducing yields markedly, often more than 50%. The main viruses worldwide are Sweet potato feathery mottle virus (SPFMV) and Sweet potato chlorotic stunt virus (SPCSV). Effects on yields by SPFMV or SPCSV alone are minor, or but in complex infection by the two or other viruses yield losses of 50%. The orthodox way of controlling viruses in vegetative propagated crops is by supplying the growers with virus-tested planting material. High-yielding plants are tested for freedom of viruses by PCR, serology, and grafting to sweet potato virus indicator plants. After this, meristem tips are taken from those plants that reacted negative. The meristems were grown into plants which were kept under insect-proof conditions and away from other sweet potato material for distribution to farmers after another cycle of reproduction. © 2015 Elsevier Inc.

    To compare long-term outcomes of retrievable stents and permanent stents for BCS due to long-segment obstructive IVC. Between July 2000 and August 2016, 42 patients with BCS due to long-segment obstructive IVC were treated with retrievable stents (RS) and 41 patients were treated with permanent stents (PS). The retrievable stents was removed eventually after thrombus disappeared. Patients were subsequently followed-up by color Doppler sonography or CT scanning. All retrievable stent placements were successfully, and 37 retrievable stents were retrieved 8 to 29 days later. Forty-two stents were implanted in PS Group. One failure retrieval of retrievable stents occurred, and two failures of cannulations were found in PS Group. Two deaths may procedure-related and died from acute pulmonary thromboembolism perioperatively. One patient developed acute cerebral infarction and recovered after treatment. In PS Group, minor complications were found in 3 patients. The length of IVC lesion segment, length and thickness of IVC thrombus decreased significantly, and diameter of retrocaval IVC and diaphragm IVC increased significantly in both groups. During follow up, 3 patients died from liver failure in RS Group and 2 patients died in PS Group. RS Group showed a significantly higher primary patency rate than PS Group. Cumulative 1-, 3-, and 5-year secondary patency rates were 95.2%, 89.6%, 89.6% in RS Group, and 100%, 96.6%, 96.6% in PS Group (p= 0.7109). Retrievable stents is effective for BCS due to long-segment obstructive IVC, with a higher primary patency rate. This article is protected by copyright. All rights reserved.

    Acute axonal polyneuropathy and Wernicke-Korsakoff encephalopathy developed simultaneously in three patients. Nerve conduction studies (NCS) detected markedly decreased compound muscle action potentials (CMAPs) and sensory nerve action potentials (SNAPs) with minimal conduction slowing; sympathetic skin responses (SSRs) were also notably decreased. Sural nerve biopsies showed only mild axonal degeneration with scattered myelin ovoid formation. The symptoms of neuropathy lessened within two weeks after an intravenous thiamine infusion. CMAPs, SNAPs, and SSRs also increased considerably. We suggest that this is a new type of peripheral nerve impairment: physiological conduction failure with minimal conduction delay due to thiamine deficiency.

    Anastasia Black (Russian sweet pepper) of Capsicum annuum L. var. angulosum Mill. (Solanaceae) was successively extracted with hexane, acetone, methanol and 70% methanol, and the extracts were further separated into a total of twenty-three fractions by silica gel or octadecylsilane (ODS; C18) column chromatography. These extracts and fractions were investigated for their cytotoxicity, anti-human immunodeficiency virus (HIV), anti-Helicobacter pylori (H. pylori), urease inhibition and multidrug resistance (MDR) reversal activity. Some fractions of hexane and acetone extracts showed higher cytotoxic activity against three human oral tumor cell lines (squamous cell carcinoma HSC-2, HSC-3, submandibular gland carcinoma HSG) than against three normal human oral cells (gingival fibroblast HGF, pulp cell HPC, periodontal ligament fibroblast HPLF), suggesting a tumor-specific cytotoxic activity. No fractions displayed anti-HIV activity, but some hydrophobic fractions showed higher anti-H. pylori activity, urease inhibition activity and MDR reversal activity. The higher MDR activity of these fractions against MDR gene-transfected L5178 mouse lymphoma T cells may possibly be due to their higher content of carotene or polyphenol. These data suggest that Anastasia Black should be further investigated as a potent supplement for cancer chemotherapy.

    Due to depletion of global crude oil, countries are interested to alternate fuel energy resources. Presently bioethanol as a source of energy has been a subject of great interest for the industrialized countries. Therefore, there is need for efficient bioethanol production with low cost raw material and production process. Among energy crops, sweet sorghum is the best candidate for bioethanol production. It has been identified as having higher drought tolerance, lower input cost and higher biomass yield than other energy crops. In addition it has wide adoptability and tolerance to abiotic stresses. Moreover due to the shortage of water in dry and hot countries there is a need to reduce water requirement for bioethanol production and solid state fermentation could be the best process for making bioethanol in these countries. The purpose of this study is to achieve the highest ethanol production with lowest amount of water in solid state fermentation using sweet sorghum stalk. In this study the sweet sorghum particles were used for solid state fermentation. Fermentation medium were: sweet sorghum particles with nutrient media, active yeast powder and different moisture contents. The fermentation medium was incubated for 2-3 days at 30 deg C temperature. The results showed sweet sorghum particles (15% w/w) fermented in medium containing 0.5% yeast inoculums, 73.5% moisture content and 3 days incubation period produced the highest amount of ethanol (13% w/w sorghum)

    Manioc (Manihot esculenta subsp. esculenta), one of the most important tropical food crops, is commonly divided according to cyanide content into two use-categories, "sweet" and "bitter." While bitter and sweet varieties are genetically differentiated at the local scale, whether this differentiation is consistent across continents is yet unknown. • Using eight microsatellite loci, we genotyped 522 manioc samples (135 bitter and 387 sweet) from Ecuador, French Guiana, Cameroon, Gabon, Ghana, and Vanuatu. Genetic differentiation between use-categories was assessed using double principal coordinate analyses (DPCoA) with multivariate analysis of variance (MANOVA) and Jost's measure of estimated differentiation (D(est)). Genetic structure was analyzed using Bayesian clustering analysis. • Manioc neutral genetic diversity was high in all sampled regions. Sweet and bitter manioc landraces are differentiated in South America but not in Africa. Correspondingly, bitter and sweet manioc samples share a higher proportion of neutral alleles in Africa than in South America. We also found seven clones classified by some farmers as sweet and by others as bitter. • Lack of differentiation in Africa is most likely due to postintroduction hybridization between bitter and sweet manioc. Inconsistent transfer from South America to Africa of ethnobotanical knowledge surrounding use-category management may contribute to increased hybridization in Africa. Investigating this issue requires more data on the variation in cyanogenesis in roots within and among manioc populations and how manioc diversity is managed on the farm.

    Previous studies have suggested that patients who are defined as so-called sweet eaters have more difficulties to lose weight and to maintain weight loss after both conservative treatment and restrictive bariatric surgery, such as gastric banding. There is, however, no agreement on the definition of sweet eating. Also, a questionnaire to measure sweet eating is not available. Therefore, the aim of our study was to agree on a definition of sweet eating and to construct a valid and reliable questionnaire that might be of help to assess the influence of sweet eating on weight loss after bariatric surgery. A Delphi Study design was chosen to define sweet eating. Based on the Delphi rounds, a questionnaire with self-reported sweets intake was constructed and validated. Nine experts with different scientific backgrounds participated in the Delphi Study which consisted of four rounds. They finally agreed on the definition that sweet eating can be defined as an eating behavior in which at least 50% of daily consumed carbohydrates consist of simple carbohydrates and which can be triggered by emotional factors (i.e., stress). They did not include the intake of artificial sweeteners in the definition. The Dutch Sweet Eating Questionnaire built on the four Delphi rounds was tested in 138 female patients and appeared to be both valid and reliable. A shortcoming of this study is that the results may not be applicable to males and to non-Western populations. The definition and the questionnaire may be useful in future research regarding sweet eating and bariatric surgery outcomes in morbidly obese patients.

    It is generally accepted that paediatric intranasal foreign bodies should be removed in the emergency setting. In the case of a difficult to access dissolvable foreign body in an uncooperative child, the question must be raised regarding whether or not a watch and wait strategy is more appropriate. We ask: How long does it take for popular sweets (candy) to dissolve in the human nose? Five popular UK sweets were placed in the right nasal cavity of a 29-year-old male (the author) with no sino-nasal disease. Time taken to dissolve was recorded. All five sweets were completely dissolved in under one hour. A watch and wait strategy in favour of examination under anaesthetic may be a viable option in some cases. Limitations of the study include the age of the participant and size of the sweets. It is also important in practice that the clinician is able to elicit an accurate history regarding the exact nature of the foreign body. It remains prudent to perform an examination under anaesthetic of an uncooperative child with a solid or unknown nasal foreign body. However, if the clinician can be certain the foreign body is a small sugar or chocolate based sweet only, a watch and wait strategy may be a reasonable choice. © 2015 John Wiley & Sons Ltd.

  12. Finding your innovation sweet spot.

    Most new product ideas are either uninspired or impractical. So how can developers hit the innovation sweet spot--far enough from existing products to attract real interest but close enough that they are feasible to make and market? They can apply five innovation patterns that manipulate existing components of a product and its immediate environment to come up with something both ingenious and viable, say the authors. The subtraction pattern works by removing product components, particularly those that seem desirable or indispensable. Think of the legless high chair that attaches to the kitchen table. The multiplication pattern makes one or more copies of an existing component, then alters those copies in some important way. For example, the Gillette double-bladed razor features a second blade that cuts whiskers at a slightly different angle. By dividing an existing product into its component parts--the division pattern--you can see something that was an integrated whole in an entirely different light. Think of the modern home stereo--it has modular speakers, tuners, and CD and tape players, which allow users to customize their sound systems. The task unification pattern involves assigning a new task to an existing product element or environmental attribute, thereby unifying two tasks in a single component. An example is the defrosting filament in an automobile windshield that also serves as a radio antenna. Finally, the attribute dependency pattern alters or creates the dependent relationships between a product and its environment. For example, by creating a dependent relationship between lens color and external lighting conditions, eyeglass developers came up with a lens that changes color when exposed to sunlight.

    2006-03-22

    The effect of methyl jasmonate (MeJA) in terms of its induction of inherent bioactive chemicals in sweet basil (Ocimum basilicum L.) was evaluated after MeJA was sprayed on healthy basil plants. The total phenolic content of the sweet basil significantly increased after 0.1 and 0.5 mM MeJA treatments compared with the control not subjected to MeJA. Two phenolic compounds, rosmarinic acid (RA) and caffeic acid (CA), were identified as strong antioxidant constituents of the sweet basil. Their amounts also significantly increased after the MeJA treatment. In addition, eugenol and linalool increased 56 and 43%, respectively, by the 0.5 mM MeJA treatment. Due to the accumulation of RA, CA, and eugenol, which possess strong 2,2-diphenyl-1-picrylhydrazyl (DPPH*) free radical scavenging activities, the antioxidant activity of the sweet basil extract was 2.3-fold greater than that of the control after the 0.5 mM MeJA treatment. In the DPPH* assay, the EC50 values of RA, CA, and eugenol were determined as 23, 46, and 59 microM, respectively, which indicated they were 6-, 3-, and 2.4-fold more efficient than BHT (140 microM). Besides, an unidentified HPLC peak in the methanolic extract of the sweet basil was 4.3-fold higher than that of the control after the 0.5 mM MeJA treatment.

    : Ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome is a rare autosomal dominant disease caused by mutations in the p63 gene. To date, approximately 40 different p63 mutations have been identified, all heterozygous. No definitive treatments are available to counteract and resolve the progressive corneal degeneration due to a premature aging of limbal epithelial stem cells. Here, we describe a unique case of a young female patient, aged 18 years, with EEC and corneal dysfunction, who was, surprisingly, homozygous for a novel and de novo R311K missense mutation in the p63 gene. A detailed analysis of the degree of somatic mosaicism in leukocytes from peripheral blood and oral mucosal epithelial stem cells (OMESCs) from biopsies of buccal mucosa showed that approximately 80% were homozygous mutant cells and 20% were heterozygous. Cytogenetic and molecular analyses excluded genomic alterations, thus suggesting a de novo mutation followed by an allelic gene conversion of the wild-type allele by de novo mutant allele as a possible mechanism to explain the homozygous condition. R311K-p63 OMESCs were expanded in vitro and heterozygous holoclones selected following clonal analysis. These R311K-p63 OMESCs were able to generate well-organized and stratified epithelia in vitro, resembling the features of healthy tissues. This study supports the rationale for the development of cultured autologous oral mucosal epithelial stem cell sheets obtained by selected heterozygous R311K-p63 stem cells, as an effective and personalized therapy for reconstructing the ocular surface of this unique case of EEC syndrome, thus bypassing gene therapy approaches. This case demonstrates that in a somatic mosaicism context, a novel homozygous mutation in the p63 gene can arise as a consequence of an allelic gene conversion event, subsequent to a de novo mutation. The heterozygous mutant R311K-p63 stem cells can be isolated by means of clonal analysis and given their good regenerative

    To preliminarily study the feasibility of oocyte cryopreservation in postpubertal girls aged between 13 and 15 years who were at risk for premature ovarian failure due to the accelerated follicle loss associated with Turner syndrome or cancer treatments. Retrospective cohort and review of literature. Academic fertility preservation unit. Three girls diagnosed with Turner syndrome, 1 girl diagnosed with germ-cell tumor. and 1 girl diagnosed with lymphoblastic leukemia. Assessment of ovarian reserve, ovarian stimulation, oocyte retrieval, in vitro maturation, and mature oocyte cryopreservation. Response to ovarian stimulation, number of mature oocytes cryopreserved and complications, if any. Mean anti-müllerian hormone, baseline follical stimulating hormone, estradiol, and antral follicle counts were 1.30 ± 0.39, 6.08 ± 2.63, 41.39 ± 24.68, 8.0 ± 3.2; respectively. In Turner girls the ovarian reserve assessment indicated already diminished ovarian reserve. Ovarian stimulation and oocyte cryopreservation was successfully performed in all female children referred for fertility preservation. A range of 4-11 mature oocytes (mean 8.1 ± 3.4) was cryopreserved without any complications. All girls tolerated the procedure well. Oocyte cryopreservation is a feasible technique in selected female children at risk for premature ovarian failure. Further studies would be beneficial to test the success of oocyte cryopreservation in young girls. Copyright © 2014 North American Society for Pediatric and Adolescent Gynecology.

    Full Text Available Whey is a major water contaminant due to its high biochemical oxygen demand (BOD, stemming mainly from its lactose (milk sugar content. The objetive of this research was to investigate the conversion of whey into useful, value-added products. Several methods have been developed already, the most important being dehydration, production of drinks, and conversion of the sugar component into organic acids. Lactic acid including its sodium, calcium, iron and antimony salts, is a valuable product in the alimentary industry and is also a raw material in the chemical industry. To maximize lactic acid production we determined the optimal dilution rate (D carrying out eight fermentations, with D = 0.102 h-1, until the acid production was nil (D= 3.0 h-1. Working conditions were 45 ± 0.1 °C, pH 5.6 ± 0.2, and a cell concentration of 30 ± 4.0 g/L, using Lactobacillus bulgaricus, and deproteinized sweet whey as a substrate. Production of lactic acid and sodium lactate was between 0.5 and 24.37 g/L. Stability of production was reached in average after two retention times. Highest productivity was at D= 0.2 h-1 (2.5 g/Lh , where only 30% of the lactose was consumed from the substrate . Highest lactose consumption was found at D= 0.102 h-1 (53.4%, where productivity was nearly maximal (2.49g/Lh, but acid concentration (26.6% was considerably higher than at the corresponding dilution rate D= 0.2 h-1, which was 14.75 g/L.

    Sweet spot supersymmetry is a phenomenologically and cosmologically perfect framework to realize a supersymmetric world at short distance. We discuss a class of dynamical models of supersymmetry breaking and its mediation whose low-energy effective description falls into this framework. Hadron fields in the dynamical models play a role of the messengers of the supersymmetry breaking. As is always true in the models of the sweet spot supersymmetry, the messenger scale is predicted to be 10 5 GeV ∼ mess ∼ 10 GeV. Various values of the effective number of messenger fields N mess are possible depending on the choice of the gauge group

    2016-01-01

    Spring frost is a significant production hazard in nearly all temperate fruit-growing regions. Sweet cherries are among the first fruit varieties starting their development in spring and therefore highly susceptible to late frost. Temperatures at which injuries are likely to occur are widely published, but their origin and determination methods are not well documented. In this study, a standardized method was used to investigate critical frost temperatures for the sweet cherry cultivar 'Summit' under controlled conditions. Twigs were sampled at four development stages ("side green," "green tip," "open cluster," "full bloom") and subjected to three frost temperatures (-2.5, -5.0, -10.0 °C). The main advantage of this method, compared to other approaches, was that the exposition period and the time interval required to reach the target temperature were always constant (2 h). Furthermore, then, the twigs were placed in a climate chamber until full bloom, before the examination of the flowers and not further developed buds started. For the first two sampling stages (side green, green tip), the number of buds found in open cluster, "first white," and full bloom at the evaluation date decreased with the strength of the frost treatment. The flower organs showed different levels of cold hardiness and became more vulnerable in more advanced development stages. In this paper, we developed four empirical functions which allow calculating possible frost damages on sweet cherry buds or flowers at the investigated development stages. These equations can help farmers to estimate possible frost damages on cherry buds due to frost events. However, it is necessary to validate the critical temperatures obtained in laboratory with some field observations.

    Full Text Available Juvenile primary hypothyroidism causing cystic ovaries and pseudoprecocious puberty (Van-Wyk Grumbach syndrome (VWGS is well documented in literature. There are only a few reports of primary hypothyroidism presenting as ovarian cysts in adults. Here we present a case of huge bilateral ovarian cysts in adulthood as the presenting feature of VWGS due to chronic uncontrolled juvenile hypothyroidism. Large uniloculor right ovarian cyst (119 × 81 × 90 mm and a multicystic left ovary (55 × 45 × 49 mm were detected in a 24 year lady with secondary amenorrhea, galactorrhea, and palpable abdominal mass with history of neonatal jaundice, delayed milestones, short stature, and precocious menarche at age of 7.5 years age. She had elevated levels of cancer antigen (CA-125 which normalized post levothyroxine supplementation. Elevated CA-125 may lead to misdiagnosis of ovarian carcinoma and inadvertent treatment. Bilateral ovarian cysts in adults are a rare presentation of juvenile hypothyroidism. It is necessary to screen for primary hypothyroidism in patients presenting with bilateral ovarian cysts to prevent unnecessary evaluation and treatment.

  10. Imaging mass spectrometry visualizes ceramides and the pathogenesis of dorfman-chanarin syndrome due to ceramide metabolic abnormality in the skin.

    Directory of Open Access Journals (Sweden)

    Naoko Goto-Inoue

    Full Text Available Imaging mass spectrometry (IMS is a useful cutting edge technology used to investigate the distribution of biomolecules such as drugs and metabolites, as well as to identify molecular species in tissues and cells without labeling. To protect against excess water loss that is essential for survival in a terrestrial environment, mammalian skin possesses a competent permeability barrier in the stratum corneum (SC, the outermost layer of the epidermis. The key lipids constituting this barrier in the SC are the ceramides (Cers comprising of a heterogeneous molecular species. Alterations in Cer composition have been reported in several skin diseases that display abnormalities in the epidermal permeability barrier function. Not only the amounts of different Cers, but also their localizations are critical for the barrier function. We have employed our new imaging system, capable of high-lateral-resolution IMS with an atmospheric-pressure ionization source, to directly visualize the distribution of Cers. Moreover, we show an ichthyotic disease pathogenesis due to abnormal Cer metabolism in Dorfman-Chanarin syndrome, a neutral lipid storage disorder with ichthyosis in human skin, demonstrating that IMS is a novel diagnostic approach for assessing lipid abnormalities in clinical setting, as well as for investigating physiological roles of lipids in cells/tissues.

  11. A Case of Cushing’s Syndrome due to Ectopic Adrenocorticotropic Hormone Secretion from Esthesioneuroblastoma with Long Term Follow-Up after Resection

    2018-01-01

    Full Text Available We present a case of a 52-year-old male who developed Cushing’s Syndrome due to ectopic adrenocorticotrophic hormone (ACTH secretion from a large esthesioneuroblastoma (ENB of the nasal sinuses. The patient initially presented with polyuria, polydipsia, weakness, and confusion. Computed tomography scan of the head and magnetic resonance imaging showed a 7 cm skull base mass centered in the right cribriform plate without sella involvement. Work-up revealed ACTH-dependent hypercortisolemia, which did not suppress appropriately after high-dose dexamethasone. Subsequent imaging of the chest, abdomen, and pelvis did not reveal other possible ectopic sources of ACTH secretion besides the ENB. His hospital course was complicated by severe hypokalemia and hyperglycemia before successful surgical resection of the tumor, the biopsy of which showed ENB. Postoperatively, his ACTH level dropped below the limit of detection. In the ensuing 4 months, he underwent adjuvant chemoradiation with carboplatin and docetaxel with good response and resolution of hypokalemia and hyperglycemia, with no sign of recurrence as of 30 months postoperatively. His endogenous cortisol production is rising but has not completely recovered.

    Mol, Frédérique Mathilde Ulrike; Roumen, Rudi M H

    2018-04-01

    Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is a debilitating neuropathic pain condition. A small portion of patients do not respond to any currently available treatment modalities. These patients, often young women, might benefit from targeted spinal cord stimulation of the dorsal root ganglion (DRG). This retrospective case series describes five ACNES patients who were referred from a Dutch dedicated tertiary referral center to collaborating sites with extensive experience in DRG stimulation to be implanted with a DRG Axium System (St. Jude/Abbott, IL, USA) in the period of 2013-2016. Numeric pain rating scores at routine 6- and 12-month follow-up visits were analyzed. Three patients experienced >50% pain reduction at 12 months follow-up. Four patients experienced device-related complications, such as lead dislocation, lead breakage, pain at the battery site, and overstimulation. This case series suggests DRG spinal cord stimulation can be safe and effective for some patients with persistent pain due to ACNES. © 2017 International Neuromodulation Society.

  13. Unique Preservation of Neural Cells in Hutchinson- Gilford Progeria Syndrome Is Due to the Expression of the Neural-Specific miR-9 MicroRNA

    Directory of Open Access Journals (Sweden)

    Xavier Nissan

    2012-07-01

    Full Text Available One puzzling observation in patients affected with Hutchinson-Gilford progeria syndrome (HGPS, who overall exhibit systemic and dramatic premature aging, is the absence of any conspicuous cognitive impairment. Recent studies based on induced pluripotent stem cells derived from HGPS patient cells have revealed a lack of expression in neural derivatives of lamin A, a major isoform of LMNA that is initially produced as a precursor called prelamin A. In HGPS, defective maturation of a mutated prelamin A induces the accumulation of toxic progerin in patient cells. Here, we show that a microRNA, miR-9, negatively controls lamin A and progerin expression in neural cells. This may bear major functional correlates, as alleviation of nuclear blebbing is observed in nonneural cells after miR-9 overexpression. Our results support the hypothesis, recently proposed from analyses in mice, that protection of neural cells from progerin accumulation in HGPS is due to the physiologically restricted expression of miR-9 to that cell lineage.

  18. Triggered tremor sweet spots in Alaska

    Gomberg, Joan; Prejean, Stephanie

    2013-01-01

    To better understand what controls fault slip along plate boundaries, we have exploited the abundance of seismic and geodetic data available from the richly varied tectonic environments composing Alaska. A search for tremor triggered by 11 large earthquakes throughout all of seismically monitored Alaska reveals two tremor “sweet spots”—regions where large-amplitude seismic waves repeatedly triggered tremor between 2006 and 2012. The two sweet spots locate in very different tectonic environments—one just trenchward and between the Aleutian islands of Unalaska and Akutan and the other in central mainland Alaska. The Unalaska/Akutan spot corroborates previous evidence that the region is ripe for tremor, perhaps because it is located where plate-interface frictional properties transition between stick-slip and stably sliding in both the dip direction and laterally. The mainland sweet spot coincides with a region of complex and uncertain plate interactions, and where no slow slip events or major crustal faults have been noted previously. Analyses showed that larger triggering wave amplitudes, and perhaps lower frequencies (tremor. However, neither the maximum amplitude in the time domain or in a particular frequency band, nor the geometric relationship of the wavefield to the tremor source faults alone ensures a high probability of triggering. Triggered tremor at the two sweet spots also does not occur during slow slip events visually detectable in GPS data, although slow slip below the detection threshold may have facilitated tremor triggering.

    Bioethanol as a renewable transportation fuel has a great potential for energy and clean environment. Among crops sweet sorghum is one of the best feedstock for ethanol production under hot and dry climatic conditions. Because it has higher tolerance to salt and drought comparing to sugarcane and corn that are currently used for bio-fuel production in the world. Generally mills are used to extract the juice from sweet sorghum stalks. Three roller mills extract around nearly 50 percent of the juice and more mills is needed to extract higher percentage of the juice. More over under cold weather the stalks become dry and juice is not extracted from the stalk, therefore reduce harvesting period. In this study stalks were harvested, leaves were stripped from the stalks and the stalks were chopped to nearly 4 mm length and sun dried. The dry stalks were grounded to 60 mesh powder by a mill. Fermentation medium consists of 15-35% (w/w) sweet sorghum powder, micronutrients and active yeast inoculum from 0.5-1% (w/w) by submerge fermentation method. The fermentation time and temperature were 48-72 hours and 30 deg, respectively. The results showed the highest amount of ethanol (14.5 % w/w sorghum) was produced with 10% sweet sorghum powder and 1% of yeast inoculum, three day fermentation at 30 deg.

  20. The sweet spots in human communication.

    Salem, Philip

    2011-07-01

    In baseball, the sweet spot is a special place on a bat where the batter can hit the ball with the most power. It is the place where the performances of the batter and pitcher collide with maximum effect. It is the place where the dynamic tension between opponents leads to transformation. The dynamic tension in all living systems is between similarity and difference. Chaos and complexity scholars recognized this tension as amounts of information. When the amounts of information were high, but not too high, the system moved to the edge of chaos, to the complexity regime, to strange attractors, or to chaos, depending on the model. The sweet spot is that range of relative variety, just the proper mix of similarity and difference, leading to transformation. This essay contains a model of human communication as an emergent social process with its own sweet spots. The essay also includes a description of current literature highlighting tensions between similarity and difference, and there is an exploration of the potential to move from one basin of attraction to another. The primary constraints on finding communication sweet spots are paradigmatic - adopting a process orientation, discovering the proper parameters, bracketing sequences to define initial conditions, and understanding the strengths and weaknesses of various modeling techniques.

    Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth syndrome that is clinically and genetically heterogeneous. Hyperinsulinemic hypoglycemia occurs in about 50% of children with BWS and, in the majority of infants, it resolves spontaneously. However, in a small group of patients...... the hypoglycemia can be persistent and may require pancreatectomy. The mechanism of persistent hyperinsulinemic hypoglycemia in this group of patients is unclear....

    Full Text Available Traditional sweet pepper cultivars showing susceptibility to the Potato virus Y (PVY are being replaced by resistant hybrids with higher commercial value. Despite of much information about resistance source reaction and their inheritance, there is no knowledge about the genetic background of commercial resistant hybrids. Reaction of sweet pepper (Capsicum annuum L. hybrids to the Potato virus Y (PVYm such as Acuario, Magali R, Nathalie and their respective generations F2 and F3 as well as hybrids Amanda, Corteso W208, CPC-6272, Dagmar, Elisa, Magali, Margarita, Monteiro, Quantum, Vivo W205 was evaluated. Reaction to PVYm was evaluated as resistant or susceptible. Magali R and Nathalie hybrid did not show any mosaic symptoms. Magali R and Nathalie hybrids resistance is due to a single dominant gene indicating resistant versus susceptible parental lines crossing pedigree. Amanda, Acuario, Corteso W208, Dagmar, Elisa, Margarita, Monteiro, Quantum and Vivo W205, considered resistant to PVY, were highly susceptibility to PVY strain m. Hybrids, claimed as resistant to the Pepper mottle virus (PepMoV, were also resistant to PVYm.

  7. SCALING LAW OF RELATIVISTIC SWEET-PARKER-TYPE MAGNETIC RECONNECTION

    2011-01-01

    Relativistic Sweet-Parker-type magnetic reconnection is investigated by relativistic resistive magnetohydrodynamic (RRMHD) simulations. As an initial setting, we assume anti-parallel magnetic fields and a spatially uniform resistivity. A perturbation imposed on the magnetic fields triggers magnetic reconnection around a current sheet, and the plasma inflows into the reconnection region. The inflows are then heated due to ohmic dissipation in the diffusion region and finally become relativistically hot outflows. The outflows are not accelerated to ultrarelativistic speeds (i.e., Lorentz factor ≅ 1), even when the magnetic energy dominates the thermal and rest mass energies in the inflow region. Most of the magnetic energy in the inflow region is converted into the thermal energy of the outflow during the reconnection process. The energy conversion from magnetic to thermal energy in the diffusion region results in an increase in the plasma inertia. This prevents the outflows from being accelerated to ultrarelativistic speeds. We find that the reconnection rate R obeys the scaling relation R≅S -0.5 , where S is the Lundquist number. This feature is the same as that of non-relativistic reconnection. Our results are consistent with the theoretical predictions of Lyubarsky for Sweet-Parker-type magnetic reconnection.

    Full Text Available The sweet potato (Ipomoea batatas L. belongs to very important crops from aspect of its world production. It is grown in large areas in Asia, on the contrary, sweet potato production in Europe presents minimal part of its total world rate. The sweet potato is less-known crop, grown only on small area in home gardens in Slovak Republic. Tubers of sweet potato are characterized by anti-diabetic, anti-oxidant and anti-proliferative properties due to the presence of valuable health-promoting components, such as carotenoids or vitamin C. The main objective of study was testing of sweet potato growing in conditions of southern Slovak Republic with focus on quantity and quality of its yield. The field trial was realised on land of the Slovak University of Agriculture in Nitra in 2015. Within trial, effect of cultivar and mulching on the selected quantitative (average tuber weight; yield per plant; yield in t.ha-1 and qualitative (total carotenoids; vitamin C parameters were tested. One certified cultivar of sweet potato 'Beauregard' was used as a comparative cultivar. Other two cultivars were marked according to the market place at which were purchased and sequentially used for seedling preparation. Tubers of first un-known cultivar were purchased in the Serbian market (marked as 'Serbian'. Tubers of next sweet potato cultivar were purchased on the market in Zagreb (marked as 'Zagrebian'. Outplating of sweet potato seedlings were realised on the 19th May 2015. The sweet potato was grown by hillock system. Each cultivar was planted in two variants (rows: non-mulching (bare soil and mulching by black non-woven textile. All variants were divided to three replications with 6 plants. Difference between rows was 1.20 m and seedlings were planted in distance of 0.30 m in row. The harvested tubers were classified in two size classes: >150 g (marketable yield and <150 g (non-marketable yield. Total carotenoid content was determined spectrophotometrically. The

    Recent studies have suggested that disomic oocyte-mediated uniparental disomy 15 (UPD(15)mat) is increased in patients with Prader-Willi syndrome (PWS) born after medically assisted reproduction (MAR). However, it remains unknown whether the increase is primarily due to MAR procedure itself or advanced maternal childbearing ages as a predisposing factor for the disomic oocyte production. To examine this matter, we studied 122 naturally conceived PWS patients (PWS-NC group) and 13 MAR-conceived patients (PWS-MAR group). The relative frequency of disomic oocyte-mediated UPD(15)mat was significantly higher in PWS-MAR group than in PWS-NC group (7/13 vs 20/122, p = 0.0045), and the maternal childbearing ages were significantly higher in PWS-MAR group than in PWS-NC group [median (range), 38 (26-45) vs 30 (19-42), p = 0.0015]. However, the logistic regression analysis revealed no significant association between the occurrence of disomic oocyte-mediated UPD(15)mat and MAR, after adjusting for childbearing age (p = 0.25). Consistent with this, while the frequency of assisted reproductive technology (ART)-conceived livebirths was higher in the PWS patients than in the Japanese general population (6.4% vs 1.1%, p = 0.00018), the distribution of childbearing ages was significantly skewed to the increased ages in the PWS patients (p < 2.2 × 10(-16) ). These results argue against a positive association of MAR procedure itself with the development of UPD(15)mat. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The purpose of this study was to improve the somatic embryo (SE) system for plant production of sweet potato (Ipomoea batatas L(Lam)). Explants isolated from SE-derived sweet potato plants were compared with control (non SE-derived) plants for their competency for SE production. Leaf explants were cultured on Murashige-Skoog (MS) medium with 2,4-dichlorophenoxy acetic acid (0.2 mg/L) and 6-benzylaminopurine (2.5 mg/L) for 2 weeks in darkness and transferred to MS medium with abscisic acid (2.5 mg/L). Explants isolated from those plants developed through somatic embryogenesis produced new somatic embryos rapidly and in higher frequency than those isolated from control plants They also appeared to grow faster in tissue culture than the control plants. Current studies in the laboratory are examining whether plants derived from a cyclical embryogenesis system (five cycles) would have any further positive impact on the rapidity and frequency of somatic embryo development. More detailed studies using electron microscopy are expected to show the point of origin of the embryos and to allow determination of their quality throughout the cyclical process. This study may facilitate improved plant micropropagation, gene transfer and germplasm conservation in sweet potato.

    Full Text Available The production of microbial protein from agricultural and agroindustrial wastes is an important way to supply the demand of this essential nutritional principle. Sweet potato (Ipomea batata tubercles damaged by weevil (Cylas formicarius are considered a waste due to their unpleasant flavor. This research deal in the characterization of sweet potato damaged by weevil, as an alternative substratefor the culture of the fodder yeast Candida utilis. It was found that the damaged tubercle had a similar composition that the healthy one, concerning dry matter, total reducing sugars, nitrogen and minerals; the high content of reducing sugars (30-40 % dry weight recommends the use of this waste as a substrate for single cell protein production. Several fungal strains were assayed to enzymatic degradation of sweet potato polysaccharides; from these ones, Aspergillus oryzae H/28-1 and Neurospora sp. were the more actives to release reducing sugars to the culture medium, being the last one the more prominent. Theyeast Candida utilis showed a satisfactory growth in media formulated in basis to weevil-damaged sweet potato, reaching reducing sugar consumptions over 80 % and biomass yields of 37-58 %; addition of urea as nitrogen source improved both parameters of the growth. The fermentation’s end-product acquired a pleasant flavor, which suggests a better palatability.

    Full Text Available Adrenocortical tumors (ACTs causing Cushing’s syndrome are extremely rare in children and adolescents. Bilateral macronodular adrenocortical disease which is a component of the McCune-Albright syndrome is the most common cause of endogenous Cushing’s syndrome. We report the case of a boy with Cushing’s syndrome who presented with obesity and growth retardation. The child was hypertensive. The biochemical evaluation revealed that his serum cortisol levels were 25.80 g/dL, with a concomitant plasma ACTH level of 10.0 pg/mL and nonsuppressed serum cortisol on high-dose dexamethasone suppression test (HDDST to be 20.38 g/dL. Computed tomography of the abdomen demonstrated a 8 × 6 × 5 cm left adrenal mass with internal calcifications. Following preoperative stabilization, laparotomy was carried out which revealed a lobulated left adrenal mass with intact capsule weighing 120 grams. Histopathological examination revealed a benign cortical neoplastic lesion, suggestive of adrenal adenoma; composed of large polygonal cells with centrally placed nuclei and prominent nucleoli without capsular and vascular invasion. On the seventh postoperative day, cortisol levels were within normal range indicating biochemical remission of Cushing’s syndrome. On followup after three months, the patient showed significant clinical improvement and had lost moderate amount of weight and adrenal imaging was found to be normal.

    Full Text Available This paper reported an unusual manifestation of a 19-year-old Chinese male patient presented with a complex phenotype of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS syndrome and Kearns–Sayre syndrome (KSS. He was admitted to our hospital with the chief complaint of “acute fever, headache and slow reaction for 21 days”. He was initially misdiagnosed as “viral encephalitis”. This Chinese man with significant past medical history of intolerating fatigue presented paroxysmal neurobehavioral attacks that started about 10 years ago. During this span, 3 or 4 attack clusters were described during which several attacks occurred over a few days. The further examination found that the hallmark signs of this patient included progressive myoclonus epilepsy, cerebellar ataxia, hearing loss, myopathic weakness, ophthalmoparesis, pigmentary retinopathy and bifascicular heart block (Wolff–Parkinson–White syndrome. By young age the disease progression is characterized by the addition of migraine, vomiting, and stroke-like episodes, symptoms of MELAS expression, which indicated completion of the MELAS/KSS overlap syndrome. The m. A3243G mitochondrial DNA mutation and single large-scale mtDNA deletions were found in this patient. This mutation has been reported with MELAS, KSS, myopathy, deafness and mental disorder with cognitive impairment. This is the first description with a MELAS/KSS syndrome in Chinese.

    Gymnemic acids are triterpene glycosides that selectively suppress taste responses to various sweet substances in humans but not in mice. This sweet-suppressing effect of gymnemic acids is diminished by rinsing the tongue with γ-cyclodextrin (γ-CD). However, little is known about the molecular mechanisms underlying the sweet-suppressing effect of gymnemic acids and the interaction between gymnemic acids versus sweet taste receptor and/or γ-CD. To investigate whether gymnemic acids directly interact with human (h) sweet receptor hT1R2 + hT1R3, we used the sweet receptor T1R2 + T1R3 assay in transiently transfected HEK293 cells. Similar to previous studies in humans and mice, gymnemic acids (100 μg/ml) inhibited the [Ca(2+)]i responses to sweet compounds in HEK293 cells heterologously expressing hT1R2 + hT1R3 but not in those expressing the mouse (m) sweet receptor mT1R2 + mT1R3. The effect of gymnemic acids rapidly disappeared after rinsing the HEK293 cells with γ-CD. Using mixed species pairings of human and mouse sweet receptor subunits and chimeras, we determined that the transmembrane domain of hT1R3 was mainly required for the sweet-suppressing effect of gymnemic acids. Directed mutagenesis in the transmembrane domain of hT1R3 revealed that the interaction site for gymnemic acids shared the amino acid residues that determined the sensitivity to another sweet antagonist, lactisole. Glucuronic acid, which is the common structure of gymnemic acids, also reduced sensitivity to sweet compounds. In our models, gymnemic acids were predicted to dock to a binding pocket within the transmembrane domain of hT1R3. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.

    2016-10-01

    Heimler syndrome (HS) is a rare recessive disorder characterized by sensorineural hearing loss (SNHL), amelogenesis imperfecta, nail abnormalities, and occasional or late-onset retinal pigmentation. It is the mildest form known to date of peroxisome biogenesis disorder caused by hypomorphic mutations of PEX1 and PEX6 genes. We report on a second Moroccan family with Heimler syndrome with early onset, severe visual impairment and important phenotypic overlap with Usher syndrome. The patient carried a novel homozygous missense variant c.3140T > C (p.Leu1047Pro) of PEX1 gene. As standard biochemical screening of blood for evidence of a peroxisomal disorder did not provide a diagnosis in the individuals with HS, patients with SNHL and retinal pigmentation should have mutation analysis of PEX1 and PEX6 genes.

    Novelty sweets resemble or can be used as toys, are brightly coloured, with striking imagery, and sold at pocket money prices. They encourage regular consumption as packaging can be resealed, leading to prolonged exposure of these high-sugar and low pH products to the oral tissues, risk factors for dental caries and erosion, respectively. To determine how children conceptualise novelty sweets and their motivations for buying and consuming them. Focus groups conducted using a brief schedule of open-ended questions, supported by novelty sweets used as prompts in the latter stages. Participants were school children (aged 9-10) from purposively selected state primary schools in Cardiff, UK. Key findings related to the routine nature of sweet eating; familiarity with and availability of novelty sweets; parental awareness and control; lack of awareness of health consequences; and the overall appeal of novelty sweets. Parents reported vagueness regarding consumption habits and permissiveness about any limits they set may have diluted the concept of treats. Flexible permissiveness to sweet buying applied to sweets of all kinds. Parents' reported lack of familiarity with novelty sweets combined with their low cost, easy availability, high sugar content, and acidity give cause for concern. © 2012 John Wiley & Sons Ltd, BSPD and IAPD.

    Sweet basil (Ocimum basilicum) is susceptible to downy mildew caused by the oomycete foliar pathogen Peronospora belbahrii. No resistant varieties of sweet basil are commercially available. Here, we report on the transfer of resistance gene Pb1 from the highly resistant tetraploid wild basil O. americanum var. americanum (PI 500945, 2n = 4x = 48) to the tetraploid susceptible O. basilicum 'Sweet basil' (2n = 4x = 48). F1 progeny plants derived from the interspecific hybridization PI 500945 × Sweet basil were resistant, indicating that the gene controlling resistance (Pb1) is dominant, but sterile due to the genetic distance between the parents. Despite their sterility, F1 plants were pollinated with the susceptible parent and 115 first backcross generation to the susceptible parent (BCs1) embryos were rescued in vitro. The emerging BCs1 plants segregated, upon inoculation, 5:1 resistant/susceptible, suggesting that resistance in F1 was controlled by a pair of dominant genes (Pb1A and Pb1A'). Thirty-one partially fertile BCs1 plants were self-pollinated to obtain BCs1-F2 or were backcrossed to Sweet basil to obtain the second backcross generation to the susceptible parent (BCs2). In total, 1 BCs1-F2 and 22 BCs2 progenies were obtained. The BCs1-F2 progeny segregated 35:1 resistant/susceptible, as expected from a tetraploid parent with two dominant resistant genes. The 22 BCs2 progenies segregated 1:1 resistant/susceptible (for a BCs1 parent that carried one dominant gene for resistance) or 5:1 (for a BCs1 parent that carried two dominant genes for resistance) at a ratio of 4:1. The data suggest that a pair of dominant genes (Pb1A and Pb1A') residing on a two homeologous chromosomes is responsible for resistance of PI 500945 against P. belbahrii.

    Wolfram syndrome, also named "DIDMOAD" (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness), is an inherited association of juvenile-onset diabetes mellitus and optic atrophy as key diagnostic criteria. Renal tract abnormalities and neurodegenerative disorder may occur in the third and fourth decade. The wolframin gene, WFS1, associated with this syndrome, is located on chromosome 4p16.1. Many mutations have been described since the identification of WFS1 as the cause of Wolfram syndrome. We identified a new homozygous WFS1 mutation (c.1532T>C; p.Leu511Pro) causing Wolfram syndrome in a large inbred Turkish family. The patients showed early onset of IDDM, diabetes insipidus, optic atrophy, sensorineural hearing impairment and very rapid progression to renal failure before age 12 in three females. Ectopic expression of the wolframin mutant in HEK cells results in greatly reduced levels of protein expression compared to wild-type wolframin, strongly supporting that this mutation is disease-causing. The mutation showed perfect segregation with disease in the family, characterized by early and severe clinical manifestations. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

Therefore, sweet gourd (100% and chili (50% with recommended fertilizer (100% of chili might be economically profitable for chili with sweet gourd intercropping system.

  10. Intrauterine Growth Restriction and the Fetal Programming of the Hedonic Response to Sweet Taste in Newborn Infants

    Full Text Available Intrauterine growth restriction is associated with increased risk for adult metabolic syndrome and cardiovascular disease, which seems to be related to altered food preferences in these individuals later in life. In this study, we sought to understand whether intrauterine growth leads to fetal programming of the hedonic responses to sweet. Sixteen 1-day-old preterm infants received 24% sucrose solution or water and the taste reactivity was filmed and analyzed. Spearman correlation demonstrated a positive correlation between fetal growth and the hedonic response to the sweet solution in the first 15 seconds after the offer (r=0.864, P=0.001, without correlation when the solution given is water (r=0.314, P=0.455. In fact, the more intense the intrauterine growth restriction, the lower the frequency of the hedonic response observed. IUGR is strongly correlated with the hedonic response to a sweet solution in the first day of life in preterm infants. This is the first evidence in humans to demonstrate that the hedonic response to sweet taste is programmed very early during the fetal life by the degree of intrauterine growth. The altered hedonic response at birth and subsequent differential food preference may contribute to the increased risk of obesity and related disorders in adulthood in intrauterine growth-restricted individuals.

    The United States is becoming more dependent on ethanol production as a renewable fuel source to decrease dependency on foreign oil. The increase in demand for renewable fuels, due in part to the Energy Policy Act of 2005, has led to increased research on alternative renewable fuels from biomass. One such avenue of research has been the conversion of biomass to renewable fuels, and specifically sweet sorghum, as an ethanol fuel stock.

    A 3 year-plot experiments were performed to determined the possible persistence of the positive effects of treating soil with compost. For this purpose, a sweet sorghum bagasse compost has been used. Experiments were achieved with sweet sorghum (Sorghum bicolor. L. Moench) vr Dale as energy crop. Similar sorghum productivities were obtained both in plots with consecutive compost applications and in plots amended with mineral fertilizers. No residual effect after three years has been detected. It could be due to the low dose of compost application. (Author) 27 refs.

    Both the percentage of starch transformed by saccharification with malt and the alcohol fermentation efficiency for four varieties of sweet sorghum is determined, and it is compared with those of a corn sample. Seeds of the varieties with low peel content yield values comparable to those of corn. Seeds of the varieties with high peel content give values lower than those of the low peel content, but, if they are previously peeled, the yield of both, in terms of transformed starch and alcohol produced, is improved, the values approaching those obtained with corn.

    The SWEET (sugars will eventually be exported transporters) proteins are sugar efflux transporters containing the MtN3_saliva domain, which affects plant development as well as responses to biotic and abiotic stresses. These proteins have not been functionally characterized in the tetraploid cotton, Gossypium hirsutum , which is a widely cultivated cotton species. In this study, we comprehensively analyzed the cotton SWEET gene family. A total of 55 putative G. hirsutum SWEET genes were identified. The GhSWEET genes were classified into four clades based on a phylogenetic analysis and on the examination of gene structural features. Moreover, chromosomal localization and an analysis of homologous genes in Gossypium arboreum , Gossypium raimondii , and G. hirsutum suggested that a whole-genome duplication, several tandem duplications, and a polyploidy event contributed to the expansion of the cotton SWEET gene family, especially in Clade III and IV. Analyses of cis -acting regulatory elements in the promoter regions, expression profiles, and artificial selection revealed that the GhSWEET genes were likely involved in cotton developmental processes and responses to diverse stresses. These findings may clarify the evolution of G. hirsutum SWEET gene family and may provide a foundation for future functional studies of SWEET proteins regarding cotton development and responses to abiotic stresses.

    Ehlers-Danlos syndrome classical type is a connective tissue disorder characterized by skin hyperextensibility, atrophic scarring, and joint hypermobility. The condition typically results from mutations in COL5A1 or COL5A2 leading to the functional haploinsufficiency. Here, we report of a 24-year-old male with mild intellectual disability, dysmorphic features, and a phenotype consistent with Ehlers-Danlos syndrome classical type. A copy number variant-calling algorithm from panel sequencing data identified the deletions exons 2-11 and duplications of exons 12-67 within COL5A1. Array comparative genomic hybridization confirmed a 94 kb deletion at 9q34.3 involving exons 2-11 of COL5A1, and a 3.4 Mb duplication at 9q34.3 involving exons 12-67 of COL5A1. © 2018 Japanese Teratology Society.

    Leigh syndrome (LS), or subacute necrotizing encephalomyelopathy, is a genetically heterogeneous, relentlessly progressive, devastating neurodegenerative disorder that usually presents in infancy or early childhood. A diagnosis of Leigh-like syndrome may be considered in individuals who do not fulfil the stringent diagnostic criteria but have features resembling Leigh syndrome.We describe a unique presentation of Leigh-like syndrome in a 3-year-old boy with elevated 3-hydroxyisovalerylcarnitine (C5-OH) on newborn screening (NBS). Subsequent persistent plasma elevations of C5-OH and propionylcarnitine (C3) as well as fluctuating urinary markers were suggestive of multiple carboxylase deficiency (MCD). Normal enzymology and mutational analysis of genes encoding holocarboxylase synthetase (HLCS) and biotinidase (BTD) excluded MCD. Biotin uptake studies were normal excluding biotin transporter deficiency. His clinical features at 13 months of age comprised psychomotor delay, central hypotonia, myopathy, failure to thrive, hypocitrullinemia, recurrent episodes of decompensation with metabolic keto-lactic acidosis and an episode of hyperammonemia. Biotin treatment from 13 months of age was associated with increased patient activity, alertness, and attainment of new developmental milestones, despite lack of biochemical improvements. Whole exome sequencing (WES) analysis failed to identify any other variants which could likely contribute to the observed phenotype, apart from the homoplasmic (100%) m.8993T>G variant initially detected by mitochondrial DNA (mtDNA) sequencing.Hypocitrullinemia has been reported in patients with the m.8993T>G variant and other mitochondrial disorders. However, persistent plasma elevations of C3 and C5-OH have previously only been reported in one other patient with this homoplasmic mutation. We suggest considering the m.8993T>G variant early in the diagnostic evaluation of MCD-like biochemical disturbances, particularly when associated with

    Microphthalmic syndrome 9 (OMIM601186) is a genetically and phenotypically variable condition, comprising anophthalmia, pulmonary hypoplasia, diaphragmatic hernia, and cardiac malformations (PDAC syndrome). Reported cases have all been associated with fetal/neonatal death or developmental delay. Recessive stimulated by retinoic acid gene 6 homolog (STRA6) mutations have recently been identified as the cause of cases of PDAC in which distinct, "bushy" eyebrows have been observed. We describe a patient with clinical anophthalmia, bushy eyebrows, patent ductus arteriosus, and normal development at age 30 months, who is a compound heterozygote for two novel STRA6 missense mutations. This patient's phenotype is consistent with the multisystemic malformations of PDAC syndrome, but is somewhat milder. This is the first living patient with compound heterozygous STRA6 mutations, which may explain her milder phenotype. We conclude that STRA6 analysis should be considered in all patients with clinical anophthalmia. Genetic counseling should be cautious with respect to long-term developmental outcomes.

    An increasing number of reports describe mutations in mitochondrial DNA coding regions, especially in mitochondrial DNA- encoded nicotinamide adenine dinucleotide dehydrogenase subunit genes of the respiratory chain complex I, as causing early-onset Leigh syndrome. The authors report the molecular findings in a 24-year-old patient with juvenile-onset Leigh syndrome presenting with optic atrophy, ataxia dystonia, and epilepsy. A brain magnetic resonance imaging revealed bilateral basal ganglia and thalamic hypointensities, and a magnetic resonance spectroscopy revealed an increased lactate peak. The authors identified a T14487C change causing M63V substitution in the mitochondrial ND6 gene. The mutation was heteroplasmic in muscle and blood samples, with different mutation loads, and was absent in the patient's mother's urine and blood samples. They suggest that the T14487C mtDNA mutation should be analyzed in Leigh syndrome, presenting with optic atrophy, ataxia, dystonia, and epilepsy, regardless of age.

Manufacturers now pay more attention to green, environmentally friendly production processes. Two significant tools that can facilitate such a goal are life cycle assessment (LCA and ecological footprint (EF. This study aimed to analyse and determine the damage to the environment, focusing on the canned fruit and vegetable processing. Canned sweet corn (340 g was selected for the case study. All inputs and outputs associated with the product system boundary were collected through field surveys. The acquired inventory was then analysed and evaluated using both LCA and EF methodology. The results were converted into an area of biologically productive land and presented as global hectares (gha. The ecological footprint of one can of sweet corn was calculated as 6.51E-04 gha. The three factors with the highest impact on ecological footprint value were the corn kernels used in the process, the packaging and steam, equivalent to 2.93E-04 gha, 1.19E-04 gha and 1.17E-04 gha respectively. To promote the sustainable development, the company should develop new technology or utilize better management techniques to reduce the ecological footprint of canned food production.

    Full Text Available Harvesting stage of sweet sorghum (Sorghum bicolor L. Moench cane is an important aspect in the content of sugar for production of industrial alcohol. Four sweet sorghum genotypes were evaluated for harvesting stage in a randomized complete block design. In order to determine sorghum harvest growth stage for bioethanol production, sorghum canes were harvested at intervals of seven days after anthesis. The genotypes were evaluated at different stages of development for maximum production of bioethanol from flowering to physiological maturity. The canes were crushed and juice fermented to produce ethanol. Measurements of chlorophyll were taken at various stages as well as panicles from the harvested canes. Dried kernels at 14% moisture content were also weighed at various stages. Chlorophyll, grain weight, absolute ethanol volume, juice volume, cane yield, and brix showed significant (p=0.05 differences for genotypes as well as the stages of harvesting. Results from this study showed that harvesting sweet sorghum at stages IV and V (104 to 117 days after planting would be appropriate for production of kernels and ethanol. EUSS10 has the highest ethanol potential (1062.78 l ha−1 due to excellent juice volume (22976.9 l ha−1 and EUSS11 (985.26 l ha−1 due to its high brix (16.21.

    Full Text Available Abstract Background Drug-Induced Hypersensitivity Syndrome (DIHS is a severe and rare systemic reaction triggered by a drug (usually an antiepileptic drug. We present a case of DISH and we review studies on the clinical features and treatment of DIHS, and on its pathogenesis in which two elements (Herpesvirus infection and the drug interact with the immune system to trigger such a syndrome that can lead to death in about 20% of cases. Case presentation We report the case of a 26-year old woman with fever, systemic maculopapular rash, lymphadenopathy, hepatitis and eosinophilic leukocytosis. She had been treated with antibiotics that gave no benefit. She was taking escitalopram and lamotrigine for a bipolar disease 30 days before fever onset. Because the patient's general condition deteriorated, betamethasone and acyclovir were started. This treatment resulted in a mild improvement of symptoms. Steroids were rapidly tapered and this was followed with a relapse of fever and a worsening of laboratory parameters. Human herpesvirus 6 (HHV-6 DNA was positive as shown by PCR. Drug-Induced Hypersensitivity Syndrome (DIHS was diagnosed. Symptoms regressed on prednisone (at a dose of 50 mg/die that was tapered very slowly. The patient recovered completely. Conclusions The search for rare causes of fever led to complete resolution of a very difficult case. As DIHS is a rare disease the most relevant issue is to suspect and include it in differential diagnosis of fevers of unknown origin. Once diagnosed, the therapy is easy (steroidal administration and often successful. However our case strongly confirms that attention should be paid on the steroidal tapering that should be very slow to avoid a relapse.

    Full Text Available Spontaneous rapture with consequent retroperitoneal hemorrhage (Wunderlich’s syndrome is the complication mostly feared from large renal angiomyolipomas (RAMLs. In hemodynamic stable patients, minimal invasive therapies have superseded open surgery as the mainstay of treatment, with contemporary cases mostly treated by selective arterial embolization. Robotic-assisted laparoscopic partial nephrectomy (RALPN is an established minimal access treatment that has been used in the past for benign and malignant lesions of the kidney in the elective setting, but rarely in urgent situations as primary treatment.

    Taste of a chemical compounds present in food stimulates us to take in nutrients and avoid poisons. However, the perception of taste greatly depends on the genetic as well as evolutionary perspectives. The aim of this work was the development and validation of a machine learning model based on molecular fingerprints to discriminate between sweet and bitter taste of molecules. BitterSweetForest is the first open access model based on KNIME workflow that provides platform for prediction of bitter and sweet taste of chemical compounds using molecular fingerprints and Random Forest based classifier. The constructed model yielded an accuracy of 95% and an AUC of 0.98 in cross-validation. In independent test set, BitterSweetForest achieved an accuracy of 96 % and an AUC of 0.98 for bitter and sweet taste prediction. The constructed model was further applied to predict the bitter and sweet taste of natural compounds, approved drugs as well as on an acute toxicity compound data set. BitterSweetForest suggests 70% of the natural product space, as bitter and 10 % of the natural product space as sweet with confidence score of 0.60 and above. 77 % of the approved drug set was predicted as bitter and 2% as sweet with a confidence scores of 0.75 and above. Similarly, 75% of the total compounds from acute oral toxicity class were predicted only as bitter with a minimum confidence score of 0.75, revealing toxic compounds are mostly bitter. Furthermore, we applied a Bayesian based feature analysis method to discriminate the most occurring chemical features between sweet and bitter compounds from the feature space of a circular fingerprint.

Anti-glomerular basement membrane (AGBM antibodies test was send. He developed massive alveolar haemorrhage in the resolution phase of atypic pneumonia. Laboratory examination revealed proteinuria of 20 mg/ dl, anemia Hb of 8 g/dl, hematocrit of 25%, microscopic hematuria of 350 erythrocite /HPF. AGBM antibodies was found as positive. GPS was diagnosed. Early immunosuppressive treatment with pulse methylprednisolone and cyclophosphamide and plazmaferez was started. Noninvasive positive pressure ventilation (NPPV was used for severe hypoxemia. Haemolytic anemia and thrombocytopenia developed under plasmaphresis treatment. Early treatment resulted with remmission. In conclusion, the current case showed that Goodpasture’s syndrome may have a favorable prognosis with early diagnosis and proper treatments including NPPV.

    Prader-Willi syndrome (PWS) is a complex, multisystem genetic disorder characterized by endocrine, neurologic, and behavioral abnormalities. We report the first case of an unbalanced de novo reciprocal translocation of chromosomes 15 and 19, 45,XY,-15,der(19)t(15;19)(q12;p13.3), resulting in monosomy for the PWS critical chromosome region. Our patient had several typical features of PWS including infantile hypotonia, a poor suck and feeding difficulties, tantrums, skin picking, compulsions, small hands and feet, and food seeking, but not hypopigmentation, a micropenis, cryptorchidism or obesity as common findings seen in PWS at the time of examination at 6 years of age. He had seizures noted from 1 to 3 years of age and marked cognitive delay. High-resolution SNP microarray analysis identified an atypical PWS type I deletion in chromosome 15 involving the proximal breakpoint BP1. The deletion extended beyond the GABRB3 gene but was proximal to the usual distal breakpoint (BP3) within the 15q11q13 region, and GABRA5, GABRG3, and OCA2 genes were intact. No deletion of band 19p13.3 was detected; therefore, the patient was not at an increased risk of tumors from the Peutz-Jeghers syndrome associated with a deletion of the STK11 gene. © 2016 S.

    The present study aims to improve the sweet aftertaste and overall acceptability of green tea infusion by hydrolyzing (-)-epigallocatechin gallate (EGCG) and (-)-epicatechin gallate (ECG) with tannase. The results showed that the intensity of the sweet aftertaste and the score of overall acceptability of the green tea infusion significantly increased with the extension of the hydrolyzing treatment. (-)-Epigallocatechin (EGC) and (-)-epicatechin (EC) were found to be the main contributors for the sweet aftertaste, based on a trial compatibility with EGCG, ECG, EGC, and EC monomers, and a synergistic action between EGC and EC to sweet aftertaste was observed. A 2.5:1 (EGC/EC) ratio with a total concentration of 3.5 mmol/L gave the most satisfying sweet aftertaste, and the astringency significantly inhibited the development of the sweet aftertaste. These results can help us to produce a tea beverage with excellent sweet aftertaste by hydrolyzing the green tea infusion with tannase. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Several epidemiologic studies have reported a positive association between breast cancer risk and high intake of sweets, which may be due to an insulin-related mechanism. We investigated this association in a population-based case-control study of 1,434 cases and 1,440 controls from Long Island, NY. Shortly after diagnosis, subjects were interviewed in-person to assess potential breast cancer risk factors, and self-completed a modified Block food frequency questionnaire, which included 11 items pertaining to consumption of sweets (sweet beverages, added sugars, and various desserts) in the previous year. Using unconditional logistic regression models, we estimated the association between consumption of sweets and breast cancer. Consumption of a food grouping that included dessert foods, sweet beverages, and added sugars was positively associated with breast cancer risk [adjusted odds ratio (OR) comparing the highest to the lowest quartile: 1.27, 95% confidence interval (CI): 1.00-1.61]. The OR was slightly higher when only dessert foods were considered (OR: 1.55, 95% CI: 1.23-1.96). The association with desserts was stronger among pre-menopausal women (OR: 2.00, 95% CI: 1.32-3.04) than post-menopausal women (OR: 1.40, 95% CI: 1.07-1.83), although the interaction with menopause was not statistically significant. Our study indicates that frequent consumption of sweets, particularly desserts, may be associated with an increased risk of breast cancer. These results are consistent with other studies that implicate insulin-related factors in breast carcinogenesis.

    Background Reducing sugar consumption is a primary focus of current global public health policy. Achieving 5% of total energy from free sugars will be difficult acknowledging the concentration of free sugars in sugar sweetened beverages, confectionery and as hidden sugars in many savoury items. The expansion of the novelty sweet market in the UK has significant implications for children and young adults as they contribute to dental caries, dental erosion and obesity.Objective To identify the most available types of novelty sweets within the high school fringe in Cardiff, UK and to assess their price range and where and how they were displayed in shops.Subjects and methods Shops within a ten minute walking distance around five purposively selected high schools in the Cardiff aea representing different levels of deprivation were visited. Shops in Cardiff city centre and three supermarkets were also visited to identify the most commonly available novelty sweets.Results The ten most popular novelty sweets identified in these scoping visits were (in descending order): Brain Licker, Push Pop, Juicy Drop, Lickedy Lips, Big Baby Pop, Vimto candy spray, Toxic Waste, Tango candy spray, Brain Blasterz Bitz and Mega Mouth candy spray. Novelty sweets were located on low shelves which were accessible to all age-groups in 73% (14 out of 19) of the shops. Novelty sweets were displayed in the checkout area in 37% (seven out of 19) shops. The price of the top ten novelty sweets ranged from 39p to £1.Conclusion A wide range of acidic and sugary novelty sweets were easily accessible and priced within pocket money range. Those personnel involved in delivering dental and wider health education or health promotion need to be aware of recent developments in children's confectionery. The potential effects of these novelty sweets on both general and dental health require further investigation.

  8. Medieval emergence of sweet melons, Cucumis melo (Cucurbitaceae).

    Sweet melons, Cucumis melo, are a widely grown and highly prized crop. While melons were familiar in antiquity, they were grown mostly for use of the young fruits, which are similar in appearance and taste to cucumbers, C. sativus. The time and place of emergence of sweet melons is obscure, but they are generally thought to have reached Europe from the east near the end of the 15th century. The objective of the present work was to determine where and when truly sweet melons were first developed. Given their large size and sweetness, melons are often confounded with watermelons, Citrullus lanatus, so a list was prepared of the characteristics distinguishing between them. An extensive search of literature from the Roman and medieval periods was conducted and the findings were considered in their context against this list and particularly in regard to the use of the word 'melon' and of adjectives for sweetness and colour. Medieval lexicographies and an illustrated Arabic translation of Dioscorides' herbal suggest that sweet melons were present in Central Asia in the mid-9th century. A travelogue description indicates the presence of sweet melons in Khorasan and Persia by the mid-10th century. Agricultural literature from Andalusia documents the growing of sweet melons, evidently casabas (Inodorous Group), there by the second half of the 11th century, which probably arrived from Central Asia as a consequence of Islamic conquest, trade and agricultural development. Climate and geopolitical boundaries were the likely causes of the delay in the spread of sweet melons into the rest of Europe.

    Leptin is known to selectively suppress neural and behavioral responses to sweet-tasting compounds. However, the molecular basis for the effect of leptin on sweet taste is not known. Here, we report that leptin suppresses sweet taste via leptin receptors (Ob-Rb) and KATP channels expressed selectively in sweet-sensitive taste cells. Ob-Rb was more often expressed in taste cells that expressed T1R3 (a sweet receptor component) than in those that expressed glutamate-aspartate transporter (a marker for Type I taste cells) or GAD67 (a marker for Type III taste cells). Systemically administered leptin suppressed taste cell responses to sweet but not to bitter or sour compounds. This effect was blocked by a leptin antagonist and was absent in leptin receptor-deficient db/db mice and mice with diet-induced obesity. Blocking the KATP channel subunit sulfonylurea receptor 1, which was frequently coexpressed with Ob-Rb in T1R3-expressing taste cells, eliminated the effect of leptin on sweet taste. In contrast, activating the KATP channel with diazoxide mimicked the sweet-suppressing effect of leptin. These results indicate that leptin acts via Ob-Rb and KATP channels that are present in T1R3-expressing taste cells to selectively suppress their responses to sweet compounds. © 2015 by the American Diabetes Association.

    As one of the important non-grain energy crops, sweet sorghum has attracted the attention of scientific community and decision makers of the world since decades. But insufficient study has been done about the spatial suitability distribution and ethanol potential of sweet sorghum in China. This paper attempts to probe into the spatial distribution and ethanol potential of sweet sorghum in China by ArcGIS methods. Data used for the analysis include the spatial data of climate, soil, topography and land use, and literatures relevant for sweet sorghum studies. The results show that although sweet sorghum can be planted in the majority of lands in China, the suitable unused lands for large-scale planting (unit area not less than 100 hm 2 ) are only as much as 78.6 x 10 4 hm 2 ; and the productive potentials of ethanol from these lands are 157.1 x 10 4 -294.6 x 10 4 t/year, which can only meet 24.8-46.4% of current demand for E10 (gasoline mixed with 10% ethanol) in China (assumption of the energy efficiency of E10 is equivalent to that of pure petroleum). If all the common grain sorghum at present were replaced by sweet sorghum, the average ethanol yield of 244.0 x 10 4 t/year can be added, and thus the productive potentials of sweet sorghum ethanol can satisfy 63.2-84.9% of current demand for E10 of China. In general, Heilongjiang, Jilin, Inner Mongolia and Liaoning rank the highest in productive potentials of sweet sorghum ethanol, followed by Hebei, Shanxi, Sichuan, and some other provinces. It is suggested that these regions should be regarded as the priority development zones for sweet sorghum ethanol in China.

    The objective of this study is to investigate the change in physicochemical properties and digestibility of starches isolated from colored sweet potato varieties under heat-moisture treatment (HMT) or annealing treatment (ANN). The results showed that morphology and X-ray diffraction patterns of the sweet potato starches remained unchanged after the HMT or ANN. The HMT significantly reduced peak viscosity, breakdown and setback and significantly increased pasting temperature, trough and final viscosities of the sweet potato starches. The swelling powers and solubility of the heat-moisture treated starches were significantly lower than those of the native or annealed starches. The decreased rapid digestible starch and the increased slowly digestible and resistant starch contents of the sweet potato starches after HMT or ANN as compared to those of the native starches were observed. The resistant starch (RS) contents of the heat-moisture treated sweet potato starches were in a range of 30.6-39.3%, significantly higher than those of the annealed starches (28.8-32.0%). The strong impact of the HMT on physicochemical properties and RS formation of the sweet potato starches compared to the ANN might be due to the high stability of the occurred interactions between starch molecules and amylopectin chains during treatment.

    Some clonal lines of resistance to black rot were obtained from M 1 V 3 of Xu-18 variety. Through some regional tests, provincial yield trial and production test, the mutant line Nong-Da 601 (12-11-8) as spring sweet potato showed a better yield than the control, the dry matter content of Nong-Da 601 was also better than that of control, further more, the resistance to black rot of mutant selected in M 1 V 3 could be passed onto their progeny. The analysis of esterase isozyme showed zymogram variation between Nong-Da 601 and Xu-18. From the observation of the root tip cells, the chromosome bridge appeared obviously after irradiation, but the frequency of chromosome aberration in M 1 V 6 was decreased almost to the level of control (Xu-18). It seems that the changes of disease resistance from susceptible to resistant by irradiation was not due to chromosome aberration but due to gene mutation

    Herbicides are pesticides used to eradicate unwanted plants in both crop and non-crop environments. These chemistries are toxic to weeds due to inhibition of key enzymes or disruption of essential biochemical processes required for weedy plants to survive. Crops can survive systemic herbicidal applications through various forms of detoxification, including metabolism that can be enhanced by safeners. Field studies were conducted near Louisville, Tennessee and Painter, Virginia to determine how the herbicides mesotrione, topramezone, nicosulfuron, and atrazine applied with or without the safener isoxadifen-ethyl would impact the nutritional quality of "Incredible" sweet corn ( Zea mays L. var. rugosa). Several herbicide treatments increased the uptake of the mineral elements phosphorus, magnesium, and manganese by 8-75%. All herbicide treatments increased protein content by 4-12%. Applied alone, nicosulfuron produced similar levels of saturated, monounsaturated, and polyunsaturated fatty acids when compared to the nontreated check, but when applied with isoxadifen-ethyl, fatty acids increased 8 to 44% relative to the check or control. Nicosulfuron plus isoxadifen-ethyl or topramezone or the combination of all three actives increased the concentrations of fructose and glucose (40-68%), whereas reducing levels of maltose or sucrose when compared to the nontreated check (-15 to -21%). Disruptions in biochemical pathways in plants due to the application of herbicides, safeners, or other pesticides have the potential to alter the nutrient quality, taste, and overall plant health associated with edible crops.

    The following "Sweet 16" rules included in this paper derive from a longer paper by APPL Director Dr. Edward Hoffman and myself entitled " 99 Rules for Managing Faster, Better, Cheaper Projects." Our sources consisted mainly of "war stories" told by master project managers in my book Simultaneous Management: Managing Projects in a Dynamic Environment (AMACOM, The American Management Association, 1996). The Simultaneous Management model was a result of 10 years of intensive research and testing conducted with the active participation of master project managers from leading private organizations such as AT&T, DuPont, Exxon, General Motors, IBM, Motorola and Procter & Gamble. In a more recent study, led by Dr. Hoffman, we learned that master project managers in leading public organizations employ most of these rules as well. Both studies, in private and public organizations, found that a dynamic environment calls for dynamic management, and that is especially clear in how successful project managers think about their teams.

    The distribution of organelles within columella cells of sweet clover was examined by transmission electron microscopy following growth under static or clinorotating conditions. A developmentally conditioned polarity was observed, with a proximal location of the nucleus and a distal accumulation of the endoplasmic reticulum. This polarity was insensitive to clinorotation. In contrast, clinorotation altered the location of amyloplasts. Application of cytoskeletal poisons (colchicine, cytochalasin D, taxol, and phalloidin), especially during clinorotation, had interesting effects on the maintenance of columella cell polarity, with a profound effect on the extent, location, and structure of the endoplasmic reticulum. The site of cytoskeletal interactions with sedimenting amyloplasts is thought to be the amyloplast envelope. An envelope fraction, having over 17 polypeptides, was isolated using immobilized antibody technology, and will provide a means of assessing the role of specific peptides in cytoskeleton/amyloplast interactions.

Every three months, we evaluated the survival (%, shoot height, and shoot viability. In vitro conservation of the sweet potato genotypes IPB-052 and IPB-007 was obtained over three and six months, respectively, using MS medium plus 2.0 mg·L−1 of ABA at either 18 or 25°C. Genotypes IPB-072 and IPB-137 can be kept for three and six months, respectively, in MS medium without ABA at 18°C. It is possible to store IPB-052 and IPB-072 for six months and IPB-007 and IPB-137 for nine months using 30 g·L−1 of sucrose and 50% MS salts.

    This randomized double-blind multicenter trial (NCT01927861) evaluated the growth-promoting effect and safety of Norditropin ® (NN220; somatropin) in Japanese children with short stature due to Noonan syndrome. Prepubertal children aged 3-Noonan syndrome were randomized to receive GH 0.033 mg/kg/day (n = 25, mean age 6.57 years, 11 females) or 0.066 mg/kg/day (n = 26, mean age 6.06 years, eight females) for 104 weeks. Change in height standard deviation score (HSDS) from baseline was analyzed based on an ANCOVA model. Baseline HSDS was -3.24. Estimated change in HSDS [95% CI] after 104 weeks' treatment was 0.84 [0.66, 1.02] and 1.47 [1.29, 1.64] for the lower and higher doses, respectively; estimated mean difference 0.63 [0.38, 0.88], p Noonan syndrome, with a favorable safety profile. The effect was greater with 0.066 mg/kg/day compared with 0.033 mg/kg/day.

    Full Text Available Abstract Background Ataxia-Telangiectasia syndrome is characterized by progressive cerebellar dysfunction, conjuctival and cutaneous telangiectasias, severe immune deficiencies, premature aging and predisposition to cancer. Clinical and radiographic evaluation for malignancy in ataxia-telangiectasia patients is usually atypical, leading to delays in diagnosis. Case presentation We report the case of a 20 year old ataxia-telangiectasia patient with gastric adenocarcinoma that presented as complete gastric outlet obstruction. Conclusion A literature search of adenocarcinoma associated with ataxia-telangiectasia revealed 6 cases. All patients presented with non-specific gastrointestinal complaints suggestive of ulcer disease. Although there was no correlation between immunoglobulin levels and development of gastric adenocarcinoma, the presence of chronic gastritis and intestinal metaplasia seem to lead to the development of gastric adenocarcinoma. One should consider adenocarcinoma in any patient with ataxia-telangiectasia who presents with non-specific gastrointestinal complaints, since this can lead to earlier diagnosis.

    A case is reported of a 26-year-old primiparous woman in the 32nd week of gestation who presented to the emergency department with the symptoms of a severe headache, nausea and vomiting. The patient was diagnosed with preeclampsia that later progressed to eclampsia. This state was characterized by a sudden onset of a headache and diplopia that advanced to cortical blindness and precipitated significant alterations in mental status, most notable being global amnesia that resolved within 48 h. A post-partum magnetic resonance imaging of the brain in FLAIR mode revealed multiple cortico-subcortical areas of hyperintense signals suggestive of edematous lesions that chiefly involved occipital and parietal lobes with additional atypical manifestations. Such radiologic findings suggested a posterior reversible encephalopathy syndrome variant with the global amnesia as an extraordinary constituent. This unique feature should be acknowledged when treating a preeclamptic or hypertensive patient that exhibits neurological symptomatology and vision disturbances.

    Full Text Available ABSTRACT Yellow sweet potato is mostly produced by small farmers, and may be a source of energy and carotenoids in the human diet, but it is a highly perishable crop. To increase its industrial application, yellow sweet potato flour has been produced for use in bakery products. This study aimed to evaluate the technological quality and the carotenoids content in sweet breads produced with the replacement of wheat flour by 0, 3, 6, and 9% yellow sweet potato flour. Breads were characterized by technological parameters and β-carotene levels during nine days of storage. Tukey’s test (p<0.05 was used for comparison between means. The increase in yellow sweet potato flour concentrations in bread led to a decrease of specific volume and firmness, and an increase in water activity, moisture, orange coloring, and carotenoids. During storage, the most significant changes were observed after the fifth day, with a decrease in intensity of the orange color. The β-carotene content was 0.1656 to 0.4715 µg/g in breads with yellow sweet potato flour. This work showed a novel use of yellow sweet potato in breads, which brings benefits to consumers’ health and for the agricultural business.

    Yellow sweet potato is mostly produced by small farmers, and may be a source of energy and carotenoids in the human diet, but it is a highly perishable crop. To increase its industrial application, yellow sweet potato flour has been produced for use in bakery products. This study aimed to evaluate the technological quality and the carotenoids content in sweet breads produced with the replacement of wheat flour by 0, 3, 6, and 9% yellow sweet potato flour. Breads were characterized by technological parameters and β-carotene levels during nine days of storage. Tukey's test (p<0.05) was used for comparison between means. The increase in yellow sweet potato flour concentrations in bread led to a decrease of specific volume and firmness, and an increase in water activity, moisture, orange coloring, and carotenoids. During storage, the most significant changes were observed after the fifth day, with a decrease in intensity of the orange color. The β-carotene content was 0.1656 to 0.4715 µg/g in breads with yellow sweet potato flour. This work showed a novel use of yellow sweet potato in breads, which brings benefits to consumers' health and for the agricultural business.

    Full Text Available In humans, congenital and hereditary skin diseases associated with epidermal cell-cell separation (acantholysis are very rare, and spontaneous animal models of these diseases are exceptional. Our objectives are to report a novel congenital acantholytic dermatosis that developed in Chesapeake Bay retriever dogs. Nine affected puppies in four different litters were born to eight closely related clinically normal dogs. The disease transmission was consistent with an autosomal recessive mode of inheritance. Clinical signs occurred immediately after birth with superficial epidermal layers sloughing upon pressure. At three month of age, dogs exhibited recurrent superficial skin sloughing and erosions at areas of friction and mucocutaneous junctions; their coat was also finer than normal and there were patches of partial hair loss. At birth, histopathology revealed severe suprabasal acantholysis, which became less severe with ageing. Electron microscopy demonstrated a reduced number of partially formed desmosomes with detached and aggregated keratin intermediate filaments. Immunostaining for desmosomal adhesion molecules revealed a complete lack of staining for plakophilin-1 and anomalies in the distribution of desmoplakin and keratins 10 and 14. Sequencing revealed a homozygous splice donor site mutation within the first intron of PKP1 resulting in a premature stop codon, thereby explaining the inability to detect plakophilin-1 in the skin. Altogether, the clinical and pathological findings, along with the PKP1 mutation, were consistent with the diagnosis of ectodermal dysplasia-skin fragility syndrome with plakophilin-1 deficiency. This is the first occurrence of ectodermal dysplasia-skin fragility syndrome in an animal species. Controlled mating of carrier dogs would yield puppies that could, in theory, be tested for gene therapy of this rare but severe skin disease of children.

    To investigate the sudden death of a 36-year-old Chinese man, a medicolegal autopsy was performed, combining forensic pathological examinations and genetic sequencing analysis to diagnose the cause of death. Genomic DNA samples were extracted from blood and subjected to high-throughput sequencing. Major findings included a dilated aortic root with a ruptured and dissected aorta and consequent tamponade of the pericardial sac. Moreover, arachnodactyly and other skeletal deformities were noted. By sequencing the fibrillin-1 gene (FBN1), five genetic variations were found, including four previously known single nucleotide polymorphisms (SNPs) and a novel frameshift mutation, leading to the diagnosis of Marfan syndrome. The frameshift mutation (c.4921delG, p.glu1641llysFsX9) detected in exon 40 led to a stop codon after the next 8 amino acids. The four SNPs included a splice site mutation (c.3464-5 G>A, rs11853943), a synonymous mutation (p.Asn625Asn, rs25458), and two missense mutations (p.Pro1148Ala, rs140598; p.Cys472Tyr, rs4775765). Genetic screening was recommended for the relatives as it was reported that the father and brother of the deceased had died at the ages of 40 and 25, respectively, from sudden cardiac failure. The son of the deceased lacked the relevant mutations. This report emphasizes the important contribution of medicolegal postmortem analysis on the molecular pathogenesis study of Marfan syndrome and early diagnosis of at-risk relatives.

    Background and Aims Prader-Willi syndrome (PWS) is a complex, multisystem genetic disorder characterized by endocrine, neurologic and behavioral abnormalities. We report the first case of an unbalanced de-novo reciprocal translocation of chromosome 15 and 19: 45,XY,-15, der (19)t(15;19)(q12;p13.3) resulting in monosomy for the PWS chromosome critical region. We performed high resolution SNP microarray to characterize the breakpoints. Case report Our patient had several typical features for PWS including infantile hypotonia, a poor suck and feeding difficulties, tantrums, skin picking, compulsions, small hands and feet and food seeking but not hypopigmentation, a micropenis, cryptorchidism or obesity as common findings seen in PWS at the time of examination at 6 years of age. He had seizures noted from 1 to 3 years of age and marked cognitive delay. Results High resolution SNP microarray analysis identified an atypical PWS Type I deletion of chromosome 15 involving proximal breakpoint BP1. The deletion extended beyond the GABRB3 gene but was proximal to the usual distal breakpoint (BP3) within the 15q11-q13 region and GABRA5, GABRG3 and OCA2 genes were intact. Conclusion We report a case with atypical features for PWS associated with an unbalanced de-novo reciprocal translocation resulting in monosomy for the 15q11.1–15q12 with intact GABRA5, GABRG3 and OCA2 genes. No deletion of 19p13.3 band was detected therefore the patient was not at an increased risk of tumors from Peutz-Jeghers syndrome associated with a deletion of the STK11 gene. PMID:27894106

    In this study, two sh2 sweet corn cultivars (i.e., the initial seed dry weight for FT018 and TB010 was 0.16+-0.02 g/grain and 0.09+-0.01 g/grain, respectively) were used to determine the physiological characteristics of seed reserve utilization in germination. The data implied that the weight of mobilized seed reserve (WMSR) and seed reserve utilization efficiency (SRUE) increased with seed germination. FT018 exhibited higher SRUE than TB010 due to its sufficient energy production for growth. Sugar (sucrose and fructose) contents were at different levels in the germinating seed of sh2 sweet corn. The protein content and number of protein species were highest in the early stage of germination. Enzyme activity in the germinating seed indicated that enzymes for starch and sugar hydrolysis were important and that enzyme activities significantly differed at each germination stage and between the cultivars under dark conditions. Succinate dehydrogenase, sucrose synthase, and glucose-6-phosphate dehydrogenase accumulated in the late germination stage. Thus, appropriate efforts should be focused on improving the seed reserve utilization in sweet corn by identifying the physiological mechanism of germinating seed. (author)

    Shelled sweet corn kernels are prone to microbial contaminations due to high moisture and nutrient contents. Post harvest handling further aggravates the condition and makes the product highly perishable and unsafe. In freshly shelled kernels total aerobic plate count, yeast mold count and presumptive coliforms were found to be ∼ 8, 7, and 4 log cfu/g, respectively. IMViC analysis confirmed presence of opportunistic pathogens like Escherichia coli and Enterobacteraerogenes in these samples. Besides, occurrence of mycotoxin such as ochratoxin A (OTA), classified as a possible carcinogenic compound, was found to be high in sweet corn samples spiked with toxigenic strain. To address this issue, a combination process including NaOCl washing (200 ppm for 5 min), hot water blanching (60℃ for 5 min), air drying, LDPE packaging, and finally gamma radiation (5 kGy) treatment was developed. The developed combination process was found to reduce microbial load to below detectable level and quite effectively inactivated Aspergillusochraceus spores as well as pre-formed toxin. These treatments were not found to affect the contents of biochemical constituents such as total and reducing sugars, proteins, phenolics, and flavonoids during storage. Prophylactic properties in terms of antioxidant capacity and potential to suppress chemical induced mutagenesis were not affected in these samples. Physical properties and sensory qualities were also found to be similar to fresh (control). Thus, the developed combination process ensured microbiological safety and extended shelf life of sweet corn kernels up to 30 days at 4℃ . (author)

    Full Text Available Sweet maize seeds present lower physiologic quality, when compared to regular maize seeds, due to the influence of several features, such as the seed size and shape. Thus, this study aimed at evaluating the seed physiologic quality of two sweet maize cultivars (BR-401 and BR-402, separately classified according to thickness, by using slotted screen sieves (8/64" x 3/4, 9/64" x 3/4, 10/64" x 3/4, 11/64" x 3/4, 12/64" x 3/4 and 13/64" x 3/4, and width, with round screen sieves (17/64", 18/64", 19/64", 20/64", 21/64" and 22/64". For each cultivar, sorted lots were compared with the unrated batch, following a completely randomized design, in a 2x7 factorial scheme, with four replications. The biometric parameters evaluated were sieve retention, 100 seeds weight and water content. The physiologic quality was determined according to the first counting, germination, cold test, accelerated aging, electric conductivity and seedling emergence in the field. The classification with sieves improved the physiologic quality of sweet maize seeds. Seeds with intermediate thickness, for both cultivars, generally presented greater vigor. Concerning width, larger seeds, for the BR-401 cultivar, and intermediate seeds, for the BR-402 cultivar, showed better physiologic quality.

    Pitanga has been used by the Brazilian food industry mainly for juice production. This fruit shows good economic potential due to its high concentration of vitamins and minerals. The aim of the present work was to characterize the time-intensity profile of pitanga nectar sweetened with different sweeteners to verify differences on the perception of sweet and bitter tastes. The sweeteners used to replace sucrose were sucralose, aspartame, stevia 40% rebaudioside A, stevia 95% rebaudioside A, neotame, and 2:1 cyclamate/saccharin blend. Fifteen assessors were selected according to their discriminating capability and trained to participate in the time-intensity analysis for sweetness and bitterness. The samples prepared with sucralose and 2:1 cyclamate/saccharin blend presented a similar sweetness profile to the sample prepared with sucrose, and the samples prepared with sucralose and aspartame presented a similar bitterness profile to the sample prepared with sucrose. Thus, sucralose would be the most suitable sweetener to replace sucrose in pitanga nectar. © The Author(s) 2015.

    For centuries wood containers have been used in aging of wines and spirits, due to the pleasant flavors they give to the beverages. Together with oak, sweet chestnut wood (Castanea sativa) have been often used for such purpose. The maturation process involves the transfer of secondary metabolites, mainly phenolics, from the wood to the liquid. At the same time, other metabolites, such as triterpenoids and their glycosides, can also be released. Searching for the extractable triterpenoids from sweet chestnut heartwood (C. sativa), two new ursane-type triterpenoid saponins named chestnoside A (1) and chestnoside B (2), together with two known oleanen-type analogs (3 and 4) were isolated and characterized. The cytotoxicity of isolated compounds was tested against two cancer cell lines (PC3 and MCF-7), and normal lymphocytes. Breast cancer cells (MCF-7) were more affected by tested compounds than prostate cancer cells (PC3). Chestnoside B (2) exhibited the strongest cytotoxicity with an IC 50 of 12.3 μM against MCF-7 cells, lower than those of positive controls, while it was moderately active against normal lymphocytes (IC 50  = 67.2 μM). These results highlight the occurrence of triterpenoid saponins in sweet chestnut heartwood and their potential for the chemoprevention of breast cancer. Copyright © 2017 Elsevier Ltd.

    Full Text Available Caffeoylquinic acid (CQA derivatives are known to possess antioxidative potential and have many beneficial effects on human health. The present study compared the CQA contents and antioxidant activities of aerial parts of sweet potato plants. The effects of drying methods (freeze drying, and drying at 30°C, 70°C, and 100°C on these two parameters of the first fully expanded leaves were also assessed. The results indicated that the CQA derivatives were detectable in leaves, stem, and flowers of sweet potato plants (varied from 39.34 mg/g dry weight to 154.05 mg/g dry weight, with the leaves (particularly expanding and first fully expanded leaves containing more CQA derivatives than other aerial plant parts. The expanding and first fully expanded leaves also exhibited greater antioxidant activities than other aerial plant parts, possibly due to their higher contents of CQA derivatives. Drying method significantly affected the content of CQA derivatives in dried sweet potato leaf tissues. Drying treatments at both 70°C and 100°C significantly reduced the CQA derivative content and antioxidant activity in the first fully expanded leaves. Among the tested drying methods, the freeze-drying method demonstrated the preservation of the highest amount of CQA derivatives (147.84 mg/g and antioxidant property. However, 30°C cool air drying was also a desirable choice (total CQA derivative content was reduced to only 129.52 mg/g, compared to 70°C and 100°C hot air drying, for commercial-scale processing of sweet potato leaves, if the higher operation cost of freeze drying was a major concern.

    Full Text Available Mead is a traditional alcoholic beverage obtained by fermenting mead wort; however, its production still remains frequently an empirical exercise. Different meads can be produced, depending on fermentation conditions. Nevertheless, to date few studies have been developed on factors that may influence mead quality. The main objective of this work was to study the influence of sweetness and ethanol content on mead acceptability. Different meads were produced with two sweetness levels (sweet and dry meads and three ethanol contents (18, 20, 22% (v/v, adjusted by brandy addition. Afterwards, meads acceptability was evaluated by sensory analysis through a consumers’ panel (n=108 along with chemical analysis by HPLC-RID of glucose, fructose, ethanol, glycerol and acetic acid. The sweet (75 gglucose+fructose/L and dry (23 gglucose+fructose/L meads presented glycerol contents equal to 5.10±0.54 and 5.96±0.95 g/L, respectively, that were desirable since glycerol improves mead quality. Low concentrations of acetic acid were determined (0.46±0.08 and 0.57±0.09 g/L, avoiding the vinegar off-character. Concerning sensory analysis, the alcohol content of mead had no effect on the sensory attributes studied, namely, aroma, sweetness, flavour, alcohol feeling and general appreciation. Regarding sweetness, the “sweet meads” were the most appreciated by the consumers (score of 5.4±2.56, whereas the “dry meads” (score of 2.7±2.23 showed low acceptability. In conclusion, this work revealed that sweetness is a sensory key attribute for mead acceptance by the consumers, whereas ethanol content (18 to 22% (v/v is not.

    The major obstacle to a sweet sorghum-for-ethanol industry in the Piedmont of Virginia is the short harvest season of eight weeks. A Piedmont harvesting system is described that will enable the Piedmont to compete with Louisiana in production of sweet sorghum for ethanol. The cost to supply feedstock (up to the point fermentation begins) for a one million GPY ethanol plant was estimated to be $2.35/gal expected ethanol yield. This amount compared favorably with two other options

  11. Shifts in species interactions due to the evolution of functional differences between endemics and non-endemics: an endemic syndrome hypothesis.

    Directory of Open Access Journals (Sweden)

    Courtney E Gorman

    Full Text Available Species ranges have been shifting since the Pleistocene, whereby fragmentation, isolation, and the subsequent reduction in gene flow have resulted in local adaptation of novel genotypes and the repeated evolution of endemic species. While there is a wide body of literature focused on understanding endemic species, very few studies empirically test whether or not the evolution of endemics results in unique function or ecological differences relative to their widespread congeners; in particular while controlling for environmental variation. Using a common garden composed of 15 Eucalyptus species within the subgenus Symphyomyrtus (9 endemic to Tasmania, 6 non-endemic, here we hypothesize and show that endemic species are functionally and ecologically different from non-endemics. Compared to non-endemics, endemic Eucalyptus species have a unique suite of functional plant traits that have extended effects on herbivores. We found that while endemics occupy many diverse habitats, they share similar functional traits potentially resulting in an endemic syndrome of traits. This study provides one of the first empirical datasets analyzing the functional differences between endemics and non-endemics in a common garden setting, and establishes a foundation for additional studies of endemic/non-endemic dynamics that will be essential for understanding global biodiversity in the midst of rapid species extinctions and range shifts as a consequence of global change.

  12. Lipid-Lowering Pharmaceutical Clofibrate Inhibits Human Sweet Taste

    Science.gov (United States)

    Kochem, Matthew

    2017-01-01

    T1R2-T1R3 is a heteromeric receptor that binds sugars, high potency sweeteners, and sweet taste blockers. In rodents, T1R2-T1R3 is largely responsible for transducing sweet taste perception. T1R2-T1R3 is also expressed in non-taste tissues, and a growing body of evidence suggests that it helps regulate glucose and lipid metabolism. It was previously shown that clofibric acid, a blood lipid-lowering drug, binds T1R2-T1R3 and inhibits its activity in vitro. The purpose of this study was to determine whether clofibric acid inhibits sweetness perception in humans and is, therefore, a T1R2-T1R3 antagonist in vivo. Fourteen participants rated the sweetness intensity of 4 sweeteners (sucrose, sucralose, Na cyclamate, acesulfame K) across a broad range of concentrations. Each sweetener was prepared in solution neat and in mixture with either clofibric acid or lactisole. Clofibric acid inhibited sweetness of every sweetener. Consistent with competitive binding, inhibition by clofibric acid was diminished with increasing sweetener concentration. This study provides in vivo evidence that the lipid-lowering drug clofibric acid inhibits sweetness perception and is, therefore, a T1R carbohydrate receptor inhibitor. Our results are consistent with previous in vitro findings. Given that T1R2-T1R3 may in part regulate glucose and lipid metabolism, future studies should investigate the metabolic effects of T1R inhibition. PMID:27742692

    Full Text Available Background: Ipomoea batatas (L. Lam. from the family Convolvulaceae is the world’s sixth largest food crop. The tubers of Ipomoea batatas commonly known as sweet potato are consumed as a vegetable globally. The tubers contain high levels of polyphenols such as anthocyanins and phenolic acids and vitamins A, B and C, which impart a potent antioxidant activity that can translate well to show wound healing effects. To check their effects on wound healing, the peels and peel bandage were tested on various injury models in rats in the present study.Methods: The methanolic extracts of the peels and peel bandage of Ipomoea batatas tubers (sweet potato were screened for wound healing by excision and incision wound models on Wistar rats. Three types of gel formulations were prepared, viz., gel containing 3.0% (w/w peel extract, gel containing 6.0% (w/w peel extract and gel containing 10% (w/w peel extract. Betadine (5% w/w povidone iodine cream was used as a reference standard. In the incision wound model, Tensile strength of the skin was measured. Epithelization time, wound contraction, hydroxyproline content of the scab, and ascorbic acid and malondialdehyde content of the plasma were determined in the excision wound model.Results: In the incision wound model, high tensile strength of the wounded skin was observed in animals treated with the peel extract gels and the peel bandage when compared with wounded control animals. The increase in tensile strength indicates the promotion of collagen fibers and that the disrupted wound surfaces are being firmly knit by collagen. In the excision wound model, significant wound closure was observed on the 4th day in rats treated with all three gel formulations when compared with the wounded control rats.

    Sweet potato is grown extensively from tropical to temperate regions and is an important food crop worldwide. In this study, we established detection methods for 17 major sweet potato viruses using single and multiplex RT-PCR assays. To investigate the current incidence of viral diseases, we collected 154 samples of various sweet potato cultivars showing virus-like symptoms from 40 fields in 10 Korean regions, and analyzed them by RT-PCR using specific primers for each of the 17 viruses. Of the 17 possible viruses, we detected eight in our samples. Sweet potato feathery mottle virus (SPFMV) and sweet potato virus C (SPVC) were most commonly detected, infecting approximately 87% and 85% of samples, respectively. Furthermore, Sweet potato symptomless virus 1 (SPSMV-1), Sweet potato virus G (SPVG), Sweet potato leaf curl virus (SPLCV), Sweet potato virus 2 ( SPV2), Sweet potato chlorotic fleck virus (SPCFV), and Sweet potato latent virus (SPLV) were detected in 67%, 58%, 47%, 41%, 31%, and 20% of samples, respectively. This study presents the first documented occurrence of four viruses (SPVC, SPV2, SPCFV, and SPSMV-1) in Korea. Based on the results of our survey, we developed multiplex RT-PCR assays for simple and simultaneous detection of the eight sweet potato viruses we recorded.

    Full text. In order to evaluate the profile of the sex steroids gonadotropin and prolactin in polycystic ovarian syndrome (POS), 24 patients with POS were studied and compared with 20 normal women during the early follicular phase of the menstrual cycle. Radioimmunoassay techniques for androstenedione (A) and estrone (E 1 ) were standardized for the purpose of the study. Androstenedione and estrone were extracted from plasma with ethyl ether. The assays were maintained in equilibrium and the labelled hormone-antibody complex was then separated from the free hormone using dextran charcoal. The sensitivity of the method was 6.8 pg/tube for A and 3.7 pg/tube for E 1 . Nonspecific binding ws 3.4 for A and 3.3 for E 1 . The interessay error at the D50 level was 15.6 for A and 8.6 for E 1 . Patients with POS had significantly higher basal levels of LH, A, T E 1 and PRL and similar FSH and DHEA-S levels when compared with normal women. The LH/FSH ratio was significantly elevated and the A/T ratio was significantly decreased. The A/E 1 and T/E 2 ratios were elevated and the E 1 /E 2 was decreased, although the differences were not statistically significant. A positive correlation between A and E 1 was observed in patients with POS. In view of the above data, it was concluded that: the quality control parameters of the radioimmunoassay for A and E 1 standardized in the present study are considered satisfactory, and the assay could be used for diagnosis and research; the patients with POS have a different sex steroid and gonadotropin profile when compared normal women during the early follicular phase of the menstrual cycle

  17. Fatal cardiac arrhythmia and long-QT syndrome in a new form of congenital generalized lipodystrophy with muscle rippling (CGL4 due to PTRF-CAVIN mutations.

    Full Text Available We investigated eight families with a novel subtype of congenital generalized lipodystrophy (CGL4 of whom five members had died from sudden cardiac death during their teenage years. ECG studies revealed features of long-QT syndrome, bradycardia, as well as supraventricular and ventricular tachycardias. Further symptoms comprised myopathy with muscle rippling, skeletal as well as smooth-muscle hypertrophy, leading to impaired gastrointestinal motility and hypertrophic pyloric stenosis in some children. Additionally, we found impaired bone formation with osteopenia, osteoporosis, and atlanto-axial instability. Homozygosity mapping located the gene within 2 Mbp on chromosome 17. Prioritization of 74 candidate genes with GeneDistiller for high expression in muscle and adipocytes suggested PTRF-CAVIN (Polymerase I and transcript release factor/Cavin as the most probable candidate leading to the detection of homozygous mutations (c.160delG, c.362dupT. PTRF-CAVIN is essential for caveolae biogenesis. These cholesterol-rich plasmalemmal vesicles are involved in signal-transduction and vesicular trafficking and reside primarily on adipocytes, myocytes, and osteoblasts. Absence of PTRF-CAVIN did not influence abundance of its binding partner caveolin-1 and caveolin-3. In patient fibroblasts, however, caveolin-1 failed to localize toward the cell surface and electron microscopy revealed reduction of caveolae to less than 3%. Transfection of full-length PTRF-CAVIN reestablished the presence of caveolae. The loss of caveolae was confirmed by Atomic Force Microscopy (AFM in combination with fluorescent imaging. PTRF-CAVIN deficiency thus presents the phenotypic spectrum caused by a quintessential lack of functional caveolae.

    To perform a cost-effectiveness analysis of subacromial corticosteroid injection combined with exercise compared with exercise alone in patients with moderate to severe shoulder pain from subacromial impingement syndrome. A within-trial cost-effectiveness analysis with 232 patients randomized to physiotherapy-led injection combined with exercise (n = 115) or exercise alone (n = 117). The analysis was from a health care perspective with 24-week follow-up. Resource use information was collected from all patients on interventions, medication, primary and secondary care contacts, private health care use and over-the-counter purchases. The measure of outcome was quality-adjusted life years (QALYs), calculated from EQ-5D responses at baseline and three further time points. An incremental cost-effectiveness analysis was conducted. Mean per patient NHS costs (£255 vs £297) and overall health care costs (£261 vs £318) were lower in the injection plus exercise arm, but this difference was not statistically significant. Total QALYs gained were very similar in the two trial arms (0.3514 vs 0.3494 QALYs), although slightly higher in the injection plus exercise arm, indicating that injection plus exercise may be the dominant treatment option. At a willingness to pay of £20,000 per additional QALY gained, there was a 61% probability that injection plus exercise was the most cost-effective option. Injection plus exercise delivered by therapists may be a cost-effective use of resources compared with exercise alone and lead to lower health care costs and less time off work.

  19. Evaluation of multiple approaches to identify genome-wide polymorphisms in closely related genotypes of sweet cherry (Prunus avium L.

    Directory of Open Access Journals (Sweden)

    Seanna Hewitt

    Full Text Available Identification of genetic polymorphisms and subsequent development of molecular markers is important for marker assisted breeding of superior cultivars of economically important species. Sweet cherry (Prunus avium L. is an economically important non-climacteric tree fruit crop in the Rosaceae family and has undergone a genetic bottleneck due to breeding, resulting in limited genetic diversity in the germplasm that is utilized for breeding new cultivars. Therefore, it is critical to recognize the best platforms for identifying genome-wide polymorphisms that can help identify, and consequently preserve, the diversity in a genetically constrained species. For the identification of polymorphisms in five closely related genotypes of sweet cherry, a gel-based approach (TRAP, reduced representation sequencing (TRAPseq, a 6k cherry SNParray, and whole genome sequencing (WGS approaches were evaluated in the identification of genome-wide polymorphisms in sweet cherry cultivars. All platforms facilitated detection of polymorphisms among the genotypes with variable efficiency. In assessing multiple SNP detection platforms, this study has demonstrated that a combination of appropriate approaches is necessary for efficient polymorphism identification, especially between closely related cultivars of a species. The information generated in this study provides a valuable resource for future genetic and genomic studies in sweet cherry, and the insights gained from the evaluation of multiple approaches can be utilized for other closely related species with limited genetic diversity in the breeding germplasm.

    Salinity is one of the serious abiotic stresses adversely affecting the majority of arable lands worldwide, limiting the crop productivity of most of the economically important crops. Sweet basil ( Osmium basilicum ) plants were grown in a non-saline soil (EC = 0.64 dS m -1 ), in low saline soil (EC = 5 dS m -1 ), and in a high saline soil (EC = 10 dS m -1 ). There were differences between arbuscular mycorrhizal ( Glomus deserticola ) colonized plants (+AMF) and non-colonized plants (-AMF). Mycorrhiza mitigated the reduction of K, P and Ca uptake due to salinity. The balance between K/Na and between Ca/Na was improved in +AMF plants. Growth enhancement by mycorrhiza was independent from plant phosphorus content under high salinity levels. Different growth parameters, salt stress tolerance and accumulation of proline content were investigated, these results showed that the use of mycorrhizal inoculum (AMF) was able to enhance the productivity of sweet basil plants under salinity conditions. Mycorrhizal inoculation significantly increased chlorophyll content and water use efficiency under salinity stress. The sweet basil plants appeared to have high dependency on AMF which improved plant growth, photosynthetic efficiency, gas exchange and water use efficiency under salinity stress. In this study, there was evidence that colonization with AMF can alleviate the detrimental salinity stress influence on the growth and productivity of sweet basil plants.

    This study examines the feasibility of producing sweet sorghum (Sorghum bicolor (L.) Moench) as an ethanol feedstock in the southeastern United States through representative counties in Mississippi. We construct enterprise budgets along with estimates of transportation costs to estimate sweet sorghum producers' breakeven costs for producing and delivering sweet sorghum biomass. This breakeven cost for the sweet sorghum producer is used to estimate breakeven costs for the ethanol producer based on wholesale ethanol price, production costs, and transportation and marketing costs. Stochastic models are developed to estimate profits for sweet sorghum and competing crops in two representative counties in Mississippi, with sweet sorghum consistently yielding losses in both counties. -- Highlights: → We examine the economic feasibility of sweet sorghum as an ethanol feedstock. → We construct enterprise budgets along with estimates of transportation costs. → We estimate breakeven costs for producing and delivering sweet sorghum biomass. → Stochastic models determine profits for sweet sorghum in two Mississippi counties.

    These studies examined the differences in sweet taste perception and implicit attitude toward sweet between normal-weight and overweight/obese adults; and tested the effects of soft drink consumption on sweet taste, explicit preference and implicit attitude toward sweet in normal-weight subjects. In study 1, normal-weight (n = 22) and overweight/obese (n = 11) adults were assessed for sweet taste intensity and pleasantness. Implicit attitude toward sweet was assessed by implicit association test (IAT). In study 2, normal-weight, lightly active adults (n = 12) underwent one month soft drink supplementation (≈760 ml/day). This increased their daily carbohydrate intake by 2.1 ± 0.2g/kg body weight. Sweet taste perception, explicit preference and implicit attitudes to sweet were assessed. In both studies salty taste was also assessed as a contrasting perception. Overweight/obese subjects perceived sweet and salty tastes as less intense (-23% and -19%, respectively) and reported higher IAT scores for sweet than normal-weight controls (2.1-fold). The supplementation changed sweet intensity/pleasantness ratings and it increased explicit preference (2.3-fold) for sweet in a subgroup of initial sucrose-dislikers. In conclusion, overweight/obese individuals are more implicitly attracted to sweet. One month of soft drink supplementation changed sweet taste perception of normal-weight subjects.

    Full Text Available Sugar production in sweet sorghums is affected by the environment. Therefore, in this study on the effects of the genotype x environment interaction on sugar accumulation, plant traits associated with the sugar content in the stem were evaluated in ten sorghum genotypes grown in six contrasting environments. The results indicated that the stem dry weight, juice sugar concentration (°Brix, stem sugar content and juice volume were controlled by the genetic constitution of the genotype, with a large environmental contribution to their expression. The results allowed for the identification of the sweet sorghum genotypes that have a high potential for the biofuel agroindustry due to their high sugar contents in the environmental conditions of Palmira, Espinal, Cerete and Codazzi. Humid tropical environments such as Gaitan and Villavicencio were less favorable for the competitive production of sweet sorghums for bioethanol due to their low levels of solar radiation and soil fertility.

    Corn is the main source for biofuel production in North America. However, both sweet pearl millet and sweet sorghum crops represent an interesting alternative to corn for ethanol production because of their high biomass yield under a wide range of environmental conditions and high concentration of readily fermentable sugars. Coproducts such as pressing residues can be also be utilized so that nothing is lost in the process. However, in order to improve the extraction of juice for ethanol production, the pressing process of this biomass must be optimized. Preliminary experiments were therefore conducted to optimize the juice extraction from sweet pearl millet and sweet sorghum using 2 different presses, notably a screw press and a manually operated hydraulic press. Both types of biomass were either chopped finely or coarsely and were exposed to various pressures with the hydraulic press. The volume of juice extracted from both crops increased linearly with increasing pressure. Sweet sorghum appeared to be a better feedstock for ethanol production because it produced about 0.03 to 0.06 litre of juice per kg of biomass more than sweet pearl millet. Juice extraction was more effective with the screw press, but only a small difference was noted between the 2 chopping modes.

    Aroma compounds in sweet whey powder were investigated in this study. Volatiles were isolated by solvent extraction followed by solvent-assisted flavor evaporation. Fractionation was used to separate acidic from nonacidic volatiles. Gas chromatography/mass spectrometry and gas chromatography/olfactometry were used for the identification of aroma compounds. Osme methodology was applied to assess the relative importance of each aroma compound. The most aroma-intense free fatty acids detected were acetic, propanoic, butanoic, hexanoic, heptanoic, octanoic, decanoic, dodecanoic, and 9-decenoic acids. The most aroma-intense nonacidic compounds detected were hexanal, heptanal, nonanal, phenylacetaldehyde, 1-octen-3-one, methional, 2,6-dimethylpyrazine, 2,5-dimethylpyrazine, 2,3-dimethylpyrazine, 2,3,5-trimethylpyrazine, furfuryl alcohol, p-cresol, 2-acetylpyrrole, maltol, furaneol, and several lactones. This study suggested that the aroma of whey powder could comprise compounds originating from milk, compounds generated by the starter culture during cheese making, and compounds formed during the manufacturing process of whey powder.

    The pathogenesis and optimal treatments for severe acute respiratory syndrome (SARS) are unclear, although corticosteroids were used to reduce lung and systemic inflammation. Because the pulmonary pathology of porcine respiratory coronavirus (PRCV) in pigs resembles SARS, we used PRCV as a model to clarify the effects of the corticosteroid dexamethasone (DEX) on coronavirus (CoV)-induced pneumonia. Conventional weaned pigs (n = 130) in one of four groups (PRCV/phosphate-buffered saline [PBS] [n = 41], PRCV/DEX [n = 41], mock/PBS [n = 23], and mock/DEX [n = 25]) were inoculated intranasally and intratracheally with the ISU-1 strain of PRCV (1 x 10(7) PFU) or cell culture medium. DEX was administered (once daily, 2 mg/kg of body weight/day, intramuscularly) from postinoculation day (PID) 1 to 6. In PRCV/DEX pigs, significantly milder pneumonia, fewer PRCV-positive cells, and lower viral RNA titers were present in lungs early at PID 2; however, at PID 4, 10, and 21, severe bronchointerstitial pneumonia, significantly higher numbers of PRCV-positive cells, and higher viral RNA titers were observed compared to results for PRCV/PBS pigs. Significantly lower numbers of CD2(+), CD3(+), CD4(+), and CD8(+) T cells were also observed in lungs of PRCV/DEX pigs than in those of PRCV/PBS pigs at PID 8 and 10, coincident with fewer gamma interferon (IFN-gamma)-secreting cells in the tracheobronchial lymph nodes as determined by enzyme-linked immunospot assay. Our results confirm that DEX treatment alleviates PRCV pneumonia early (PID 2) in the infection but continued use through PID 6 exacerbates later stages of infection (PID 4, 10, and 21), possibly by decreasing cellular immune responses in the lungs (IFN-gamma-secreting T cells), thereby creating an environment for more-extensive viral replication. These data have potential implications for corticosteroid use with SARS-CoV patients and suggest a precaution against prolonged use based on their unproven efficacy in humans

    Full Text Available Sweet potato (Ipomoea batatas L. is a nutritious food crop and, based on the high starch content of its storage root, a potential bioethanol feedstock. Enhancing the nutritional value and starch quantity of storage roots are important goals of sweet potato breeding programs aimed at developing improved varieties for direct consumption, processing, and industrial uses. However, developing improved lines of sweet potato is challenging due to the genetic complexity of this plant and the lack of genome information. Short sequence repeat (SSR markers are powerful molecular tools for tracking important loci in crops and for molecular-based breeding strategies; however, few SSR markers and marker-trait associations have hitherto been identified in sweet potato. In this study, we identified 1,824 SSRs by using a de novo assembly of publicly available ESTs and mRNAs in sweet potato, and designed 1,476 primer pairs based on SSR-containing sequences. We mapped 214 pairs of primers in a natural population comprised of 239 germplasms, and identified 1,278 alleles with an average of 5.972 alleles per locus and a major allele frequency of 0.7702. Population structure analysis revealed two subpopulations in this panel of germplasms, and phenotypic characterization demonstrated that this panel is suitable for association mapping of starch-related traits. We identified 32, 16, and 17 SSR markers associated with starch content, β-carotene content, and starch composition in the storage root, respectively, using association analysis and further evaluation of a subset of sweet potato genotypes with various characteristics. The SSR markers identified here can be used to select varieties with desired traits and to investigate the genetic mechanism underlying starch and carotenoid formation in the starchy roots of sweet potato.

    We report an African-American family that was identified after the proposita was referred for diagnostic evaluation at 4½ months with a history of Hirschsprung and dysmorphic features typical of Waardenburg syndrome (WS). Family evaluation revealed that the father had heterochromidia irides and hypertelorism supporting the clinical diagnosis of WS; however, examination of the mother revealed characteristic facial and digital features of Coffin-Lowry syndrome (CLS). Molecular testing of the mother identified a novel 2 bp deletion (c.865_866delCA) in codon 289 of RPS6KA3 leading to a frame-shift and premature termination of translation 5 codons downstream (NM_004586.2:p.Gln289ValfsX5). This deletion also was identified in the proposita and her three sisters with a clinical suspicion of CLS, all of whom as carriers for this X-linked disorder had very subtle manifestations. The molecular confirmation of WS type 4 (Shah-Waardenburg; WS4) was not as straightforward. To evaluate WS types 1-4, multiple sequential molecular tests were requested, including Sanger sequencing of all exons, and deletion/duplication analysis using MLPA for PAX3, MITF, SOX10, EDN3 and EDNRB. Although sequencing did not identify any disease causing variants, MLPA identified a heterozygous deletion of the entire EDNRB in the father. This deletion was also found in the proposita and the oldest child. Since the heterozygous deletion was the only change identified in EDNRB, this family represents one of the few cases of an autosomal dominant inheritance of WS4 involving the endothelin pathway. Altogether, clinical evaluation of the family revealed one child to be positive for WS4 and two positive for CLS, while two children were positive for both diseases simultaneously (including the proposita) while another pair test negative for either disease. This kinship is an example of the coincidence of two conditions co-segregating in one family, with variable phenotypes requiring molecular testing to

    This work provides the bioinformatics, expression pattern and functional analyses of cryptochrome 1a from sweet sorghum (SbCRY1a), together with an exploration of the signaling mechanism mediated by SbCRY1a. Sweet sorghum [Sorghum bicolor (L.) Moench] is considered to be an ideal candidate for biofuel production due to its high efficiency of photosynthesis and the ability to maintain yield under harsh environmental conditions. Blue light receptor cryptochromes regulate multiple aspects of plant growth and development. Here, we reported the function and signal mechanism of sweet sorghum cryptochrome 1a (SbCRY1a) to explore its potential for genetic improvement of sweet sorghum varieties. SbCRY1a transcripts experienced almost 24 h diurnal cycling; however, its protein abundance showed no oscillation. Overexpression of SbCRY1a in Arabidopsis rescued the phenotype of cry1 mutant in a blue light-specific manner and regulated HY5 accumulation under blue light. SbCRY1a protein was present in both nucleus and cytoplasm. The photoexcited SbCRY1a interacted directly with a putative RING E3 ubiquitin ligase constitutive photomorphogenesis 1 (COP1) from sweet sorghum (SbCOP1) instead of SbSPA1 to suppress SbCOP1-SbHY5 interaction responding to blue light. These observations indicate that the function and signaling mechanism of cryptochromes are basically conservative between monocotyledons and dicotyledons. Moreover, SbCRY1a-overexpressed transgenic Arabidopsis showed oversensitive to abscisic acid (ABA) and salinity. The ABA-responsive gene ABI5 was up-regulated evidently in SbCRY1a transgenic lines, suggesting that SbCRY1a might regulate ABA signaling through the HY5-ABI5 regulon.

    Sweet preference has been reported to be associated with various health problems. This study examined the influence of sweet taste preference on the risk of dyslipidemia in Korean middle-aged women. The study selected 3,609 middle-aged women from the Korean Genome and Epidemiology Study (KoGES) and classified them into two groups on the basis of whether or not they preferred sweet taste. Dietary intake was analyzed using a semiquantitative food frequency questionnaire. Serum lipid profiles and anthropometric variables were measured. Subjects who preferred the sweet taste had significantly higher intakes of sugar products and sweet drink than those who did not prefer the sweet taste. Subjects who preferred the sweet taste showed higher carbohydrate and fat intake and less fiber intake than those who did not prefer the sweet taste. The serum concentrations of total cholesterol and low-density lipoprotein (LDL) cholesterol were significantly higher in subjects who preferred the sweet taste than those who did not prefer. Furthermore, subjects who preferred the sweet taste showed a significantly higher odds ratio (OR) for hypercholesterolemia (OR 1.22; 95% CI (1.01-1.45)) and hyper-LDL cholesterolemia (OR 1.33; 95% CI (1.11-1.60)) than those who did not prefer the sweet taste. Our results suggested that preference for sweet taste may increase the consumption of sugar products and sweet drinks, which is partially linked to the risk of hypercholesterolemia and hyper-LDL cholesterolemia in Korean middle-aged women.

    The SWEET (sugars will eventually be exported transporter) family is a newly characterized group of sugar transporters. In plants, the key roles of SWEETs in phloem transport, nectar secretion, pollen nutrition, stress tolerance, and plant-pathogen interactions have been identified. SWEET family genes have been characterized in many plant species, but a comprehensive analysis of SWEET members has not yet been performed in wheat. Here, 59 wheat SWEETs (hereafter TaSWEETs) were identified through homology searches. Analyses of phylogenetic relationships, numbers of transmembrane helices (TMHs), gene structures, and motifs showed that TaSWEETs carrying 3-7 TMHs could be classified into four clades with 10 different types of motifs. Examination of the expression patterns of 18 SWEET genes revealed that a few are tissue-specific while most are ubiquitously expressed. In addition, the stem rust-mediated expression patterns of SWEET genes were monitored using a stem rust-susceptible cultivar, 'Little Club' (LC). The resulting data showed that the expression of five out of the 18 SWEETs tested was induced following inoculation. In conclusion, we provide the first comprehensive analysis of the wheat SWEET gene family. Information regarding the phylogenetic relationships, gene structures, and expression profiles of SWEET genes in different tissues and following stem rust disease inoculation will be useful in identifying the potential roles of SWEETs in specific developmental and pathogenic processes.

Some hours after, he developed severe pain in his legs and a diagnosis of neuroleptic malignant syndrome (NMS was considered. Even with treatment for NMS he still complained of pain. A diagnosis of lower limb compartment syndrome (CS was done only 12 hours after the initial event, being submitted to fasciotomy in both legs, disclosing very pale muscles, due to previous ischemia. This syndrome was not explained only by facial surgery, his position and duration of the procedure. It can be explained by a sequence of events. He had a history of pain in his legs during physical exercises, usually seen in chronic compartment syndrome. He used to take anabolizant and venlafaxine, not previously related, and the agitation could be related to serotoninergic syndrome caused by interaction between venlafaxine and haloperidol. Rhabdomyolisis could lead to oedema and ischmemia in both anterior leg compartment. This report highlights the importance of early diagnosis of compartment syndrome, otherwise, even after fasciotomy, a permanent disability secondary to peripheral nerve compression could occur.Logo após ritidoplastia bilateral, um jovem de 25 anos apresentou agitação, necessitando uso de haloperidol.

    The paper presents the results on modification occurred in biochemical properties of sweet potato (Ipomea batatus L.) after gamma irradiation. Two varieties, named Victoria Ianb (a white variety) and Portocaliu (a red variety), were selected and acclimatized for the agrometeorological conditions of Romania. The samples consist of roots from both usual and experimental crops. They were irradiated in batch, one week after harvesting, with a ICPR Co-60 gamma-ray source by approx. 370 TBq, dose range 100-500 Gy, dose rate 100±5 Gy/hour, dose uniformity ±5%, temperature 10 o C, 80±5% relative humidity (rh). The irradiation doses received were checked using the Fricke ferrous sulphate dosimeter procedure. The roots were kept two months at relative darkness, 6-11 o C, 60-75% rh and analyzed from time to time (initial, 5, 7, 14, 30 and 60 days). The following parameters are analyzed by conventional methods: total and reducing sugars (in De equivalent, %, on dry weight basis), starch content and the activities of sugar metabolizing enzymes. The red variety had a better behaviour towards irradiation that the white one. The sugar contents (both total and reducing), as well as starch, varied more in the white variety. The sugar metabolizing enzyme activities were influenced by both irradiation and storage conditions. Their activities were maximal at 200 and 300 Gy, and decreased significantly at higher doses. The activities also decreased in time, their variations being higher at lower doses (100 and 200 Gy). The results showed no significant influence of gamma irradiation on storage life. The modifications induced in sugar contents and enzyme activities had maximal effects at 200-300 Gy. (author)

    A laboratory-silo study was conducted to evaluate the fermentation quality, feed-nutritive value and aerobic stability of sweet sorghum silage with or without oil-extracted microalgae supplementation. Sweet sorghum was mixed with four microalgae levels (0%, 1%, 2% and 3% on a dry matter basis; Control, M1, M2 and M3, respectively) and ensiled for 45 d. Further, the four experimental silages were subjected to an aerobic stability test lasting 7 d. All the silages except M3 silage had good fermentative characteristics with low pH and ammonia nitrogen concentrations, and high lactic acid concentrations and favorable microbial parameters. Meanwhile, oil-extracted microalgae supplementation improved the feed-nutritional value of sweet sorghum silage. Fibre (neutral detergent fibre, acid detergent fibre, acid detergent lignin and cellulose) and acid detergent insoluble protein concentrations decreased (P sweet sorghum silage by 43.8 and more than 143%, respectively, and decreased the clostridia spore counts during the stage of air exposure. Sweet sorghum silage produced with 2% oil-extracted microalgae addition was the most suitable for animal use due to the optimal balance of fermentation quality, feed-nutritional value and aerobic stability, which is merit further in vivo studies using grazing ruminants.

    Eagle syndrome occurs due to elongation of the styloid process or calcification of the stylohyoid ligament, which then may produce a pain sensation due the pressure exerted on various structures in the head and neck. When suspected, imaging helps in identifying the abnormally elongated styloid process or the calcified ligament. In recent years, three-dimensional CT (3DCT) has proved to be valuable in these cases. We report the case of a 62-year-old man with this syndrome in whom imaging with 3DCT conclusively established the diagnosis

    We undertake a critical appraisal of the existence of the so- called 'sweet spot' in ethical trade at which the interests of buyers, suppliers, and workers intersect to enable benefits for commercial buyers and suppliers and improvements in the conditions of workers at the base of global production...... networks. In turn, we take the perspectives of three central actors typically involved in ethical trade: buyers/brands, suppliers in the Global South, and workers at the base of these networks. By applying all three perspectives, we theorize about the circumstances in which the sweet spot in ethical trade...... might emerge, reflecting an amended version of Gereffi et al.'s (2005) theory of value chain governance. We conclude that the possibility of identifying a sweet spot in ethical trade improves as we move from market-based transactions toward hierarchical governance in global production networks....

    The coat protein (CP) gene of cucumber mosaic virus (CMV) was cloned from a Chinese CMV isolate, the CaMV promoter and NOS terminator added and the gene construct was transformed into both sweet pepper and tomato plants to confer resistance to CMV. Safety assessments of these genetically modified (GM) plants were conducted. It was found that these two GM products showed no genotoxicity either in vitro or in vivo by the micronucleus test, sperm aberration test and Ames test. Animal feeding studies showed no significant differences in growth, body weight gain, food consumption, hematology, blood biochemical indices, organ weights and histopathology between rats or mice of either sex fed with either GM sweet pepper or tomato diets compared with those with non-GM diets. These results demonstrate that the CMV-resistant sweet pepper and tomato are comparable to the non-GM counterparts in terms of food safety

  4. Sweet proteins – Potential replacement for artificial low calorie sweeteners

    2005-02-01

    Full Text Available Abstract Exponential growth in the number of patients suffering from diseases caused by the consumption of sugar has become a threat to mankind's health. Artificial low calorie sweeteners available in the market may have severe side effects. It takes time to figure out the long term side effects and by the time these are established, they are replaced by a new low calorie sweetener. Saccharine has been used for centuries to sweeten foods and beverages without calories or carbohydrate. It was also used on a large scale during the sugar shortage of the two world wars but was abandoned as soon as it was linked with development of bladder cancer. Naturally occurring sweet and taste modifying proteins are being seen as potential replacements for the currently available artificial low calorie sweeteners. Interaction aspects of sweet proteins and the human sweet taste receptor are being investigated.

  5. The bamboo-eating giant panda (Ailuropoda melanoleuca) has a sweet tooth: behavioral and molecular responses to compounds that taste sweet to humans.

    A growing body of behavioral and genetic information indicates that taste perception and food sources are highly coordinated across many animal species. For example, sweet taste perception is thought to serve to detect and motivate consumption of simple sugars in plants that provide calories. Supporting this is the observation that most plant-eating mammals examined exhibit functional sweet perception, whereas many obligate carnivores have independently lost function of their sweet taste receptors and exhibit no avidity for simple sugars that humans describe as tasting sweet. As part of a larger effort to compare taste structure/function among species, we examined both the behavioral and the molecular nature of sweet taste in a plant-eating animal that does not consume plants with abundant simple sugars, the giant panda (Ailuropoda melanoleuca). We evaluated two competing hypotheses: as plant-eating mammals, they should have a well-developed sweet taste system; however, as animals that do not normally consume plants with simple sugars, they may have lost sweet taste function, as has occurred in strict carnivores. In behavioral tests, giant pandas avidly consumed most natural sugars and some but not all artificial sweeteners. Cell-based assays revealed similar patterns of sweet receptor responses toward many of the sweeteners. Using mixed pairs of human and giant panda sweet taste receptor units (hT1R2+gpT1R3 and gpT1R2+hT1R3) we identified regions of the sweet receptor that may account for behavioral differences in giant pandas versus humans toward various sugars and artificial sweeteners. Thus, despite the fact that the giant panda's main food, bamboo, is very low in simple sugars, the species has a marked preference for several compounds that taste sweet to humans. We consider possible explanations for retained sweet perception in this species, including the potential extra-oral functions of sweet taste receptors that may be required for animals that consume

    SWEET (Sweet Will Eventually be Exported Transporter) proteins have been recently discovered and form one of the three major families of sugar transporters. Homologs of SWEET are found in both prokaryotes and eukaryotes. Bacterial SWEET homologs have three transmembrane segments forming a triple-helical bundle (THB) and the functional form is dimers. Eukaryotic SWEETs have seven transmembrane helical segments forming two THBs with a linker helix. Members of SWEET homologs have been shown to be involved in several important physiological processes in plants. However, not much is known regarding the biological significance of SWEET homologs in prokaryotes and in mammals. We have collected more than 2000 SWEET homologs from both prokaryotes and eukaryotes. For each homolog, we have modeled three different conformational states representing outward open, inward open and occluded states. We have provided details regarding substrate-interacting residues and residues forming the selectivity filter for each SWEET homolog. Several search and analysis options are available. The users can generate a phylogenetic tree and structure-based sequence alignment for selected set of sequences. With no metazoan SWEETs functionally characterized, the features observed in the selectivity filter residues can be used to predict the potential substrates that are likely to be transported across the metazoan SWEETs. We believe that this database will help the researchers to design mutational experiments and simulation studies that will aid to advance our understanding of the physiological role of SWEET homologs.

    The University of Arizona undertook a “pilot” project to grow sweet sorghum on a field scale (rather than a plot scale), produce juice from the sweet sorghum, deliver the juice to a bio-refinery and process it to fuel-grade ethanol. We also evaluated the bagasse for suitability as a livestock feed and as a fuel. In addition to these objectives we evaluated methods of juice preservation, ligno-cellulosic conversion of the bagasse to fermentable sugars and alternative methods of juice extraction.

    2009-01-01

    Sweet-Parker (collisional) magnetic reconnection at high Lundquist number is modified by secondary islands. Daughton et al. [Phys. Rev. Lett. 103, 065004 (2009)] suggested the Sweet-Parker model governs the fragmented current sheet segments. If true, the reconnection rate would increase by the square root of the number of secondary islands. High Lundquist number resistive magnetohydrodynamic simulations are presented which agree, in a time-averaged sense, with the predicted scaling. This result may have important implications for energy storage before a solar eruption and its subsequent release.

    Full Text Available Objectives : The aim of this study was to observe prevention of allergic reactions of Sweet Bee Venom (removing enzyme components from Bee Venom. Methods : Content analysis of Sweet Bee Venom and Bee Venom was rendered using HPLC method and characterization of Anti-Sweet Bee Venom in Rabbit Serum. Clinical observation was conducted for inducement of allergic responses to Sweet BV. Results : 1. Analyzing melittin content using HPLC, Sweet BV contained 34.9% more melittin than Bee venom pharmacopuncture at same concentration. 2. Observing chromatogram of HPLC, removal of the enzyme was successfully rendered on Sweet BV. 3. The anti-serum of Sweet BV showed high titers against melittin and bee venom and relatively low titer against phospholipase A2. 4. After conducting approximately 3,000 cases of Sweet BV administration, not a single case of generalized anaphylatic reaction occurred in clinical observation. 5. Mild compared to the bee venom pharmacopuncture, Sweet BV showed some acute hypersensitive reactions of edema, itchiness, and aching locally. 6. Sweet BV was administered on six patients with previous history of suffering from generalized acute hypersensitive reactions with the bee venom. None of the patients showed allergic reactions with Sweet BV, suggesting it can effectively prevent anaphylatic shock which may occur after the bee venom pharmacopuncture procedure. Conclusion : Summarizing above results, Sweet Bee Venom appears to be an effective measurement against allergic reactions from the bee venom pharmacopuncture especially against anaphylatic shock.

    Full Text Available The effect of autoclaving (120 °C/30 min, debranching (2% pullulanase/1 h and storage at 4 °C (DS4 or 32 °C (DS32 or 60 °C (DS60 for 24 h on starch fractions, functional, pasting, thermal and structural properties of sweet potato starch was investigated. Results showed that DS4 sample displayed the lower functional properties than other modified starches. Debranching showed a significant increase in the apparent amylose content of native starch from 18.56% to 25%. A higher yield of RS (28.76% was observed in debranched starch stored at 4 °C (DS4 due to the higher degree of retrogradation. All debranched starches showed a substantial decrease in pasting profile and higher gelatinization temperatures than in native starch. B + V X-ray diffraction pattern was observed in debranched starches with increased crystallinity value. The scanning electron micrographs of debranched starches showed rough plate-like surfaces with irregularly shaped structures were observed due to debranching and retrogradation during storage. The study concludes that a combination of autoclaving, debranching and subsequent storage at 4 °C is best technique to produce a higher amount of resistant starch in the sweet potato starch.
