    Southern tick-associated rash illness (STARI) is a rash occurring after a tick bite. It is a form of erythema migrans, an annular rash with central clearing that is almost identical with the erythema migrans seen in Lyme disease. The etiologic agent is not known but may be a Borrelia species. The tick vector is different in the two diseases. Serious systemic complications are not currently recognized with STARI but treatment with doxycycline is prudent. Differentiating STARI from Lyme disease is discussed.

    Lyme disease, the most commonly reported vector-borne disease in the United States, results from infection with Borrelia burgdorferi. Early clinical diagnosis of this disease is largely based on the presence of an erythematous skin lesion for individuals in high-risk regions. This, however, can be confused with other illnesses including southern tick-associated rash illness (STARI), an illness that lacks a defined etiological agent or laboratory diagnostic test, and is coprevalent with Lyme disease in portions of the eastern United States. By applying an unbiased metabolomics approach with sera retrospectively obtained from well-characterized patients, we defined biochemical and diagnostic differences between early Lyme disease and STARI. Specifically, a metabolic biosignature consisting of 261 molecular features (MFs) revealed that altered N -acyl ethanolamine and primary fatty acid amide metabolism discriminated early Lyme disease from STARI. Development of classification models with the 261-MF biosignature and testing against validation samples differentiated early Lyme disease from STARI with an accuracy of 85 to 98%. These findings revealed metabolic dissimilarity between early Lyme disease and STARI, and provide a powerful and new approach to inform patient management by objectively distinguishing early Lyme disease from an illness with nearly identical symptoms.

    Southern tick-associated rash illness (STARI) is a Lyme disease-like infection described in patients in the southeastern and south-central United States, where classic Lyme disease is relatively rare. STARI develops following the bite of a lone star tick (Amblyomma americanum) and is thought to be caused by infection with an "uncultivable" spirochete tentatively named Borrelia lonestari. In this study, wild lone star ticks collected from an area where B. lonestari is endemic were cocultured in an established embryonic tick cell line (ISE6). The cultures were examined by dark-field microscopy for evidence of infection, and spirochete identity and morphology were evaluated by flagellin B and 16S rRNA gene sequence, by reaction to Borrelia-wide and B. burgdorferi-specific monoclonal antibodies, and by electron microscopy. Live spirochetes were first visualized in primary culture of A. americanum ticks by dark-field microscopy 14 days after the cell culture was inoculated. The sequences of the flagellin B and 16S rRNA genes of cultured spirochetes were consistent with previously reported sequences of B. lonestari. The cultured spirochetes reacted with a Borrelia-wide flagellin antibody, but did not react with an OspA antibody specific to B. burgdorferi, by indirect fluorescent antibody testing. Electron microscopy demonstrated organisms that were free and associated with ISE6 cells, with characteristic Borrelia sp. morphology. This study describes the first successful isolation of B. lonestari in culture, providing a much needed source of organisms for the development of diagnostic assays and forming a basis for future studies investigating the role of the organism as a human disease agent.

    Full Text Available A 30-year-old Iban woman presented to a rural primary healthcare clinic located along the Batang Rejang in Sarawak. She had a 2-day history of rash, which started over her trunk and later spread to her face and limbs. What started out as individual erythematous maculopapular spots later coalesced to form larger raised blotches. The rash was extremely pruritic and affected her sleep, and hence her visit. The rash was preceded by high grade, persistent fever that was temporarily relieved by paracetamol. She also complained of malaise, arthralgia and myalgia. Her appetite had been poor since the onset of the fever. She lived in a long house at the edge of the jungle. Although she did not have a history of going into the jungle to forage, she went regularly to the river to wash clothes. Clinically, she appeared lethargic and had bilateral conjunctival injection. Her left anterior cervical lymph nodes were palpable. There were erythematous macules measuring 5 to 15 mm distributed over her whole body but predominantly over the chest and abdominal region (Figure 1. An unusual skin lesion was discovered at the right hypochondriac region. This lesion resembled a cigarette burn with a necrotic centre (Figure 2. There was no evidence of hepato-splenomegaly. Examination of the other systems was unremarkable. On further questioning, the patient admitted being bitten by a ‘kutu babi’ or mite 3 days before the onset of her fever.

    Full Text Available Rashes can occur in any part of the body. But rash which appears on face has got both psychological and cosmetic effect on the patient. Rashes on face can sometimes be very challenging to physicians and dermatologists and those associated with oral manifestations pose a challenge to dentists. Butterfly rash is a red flat facial rash involving the malar region bilaterally and the bridge of the nose. The presence of a butterfly rash is generally a sign of lupus erythematosus (LE, but it can also include a plethora of conditions. The case presented here is of a female with butterfly rash along with typical bright red discoloration of gingiva. The clinical, histopathological and biochemical investigations suggested the presence of rosacea.

    Full Text Available Adverse skin reactions are an important type of adverse drug reactions which have been reported with a wide variety of psychotropics including both typical and atypical antipsychotics. Like typical antipsychotics, atypical antipsychotics such as olanzapine, risperidone, and paliperidone have been documented to cause skin reactions. Reports of aripiprazole-induced skin reactions are sparse. We report a case of skin rash that developed after starting aripiprazole in a male patient suffering from schizophrenia and which remitted after the drug was stopped.

    Crushell, Ellen

    2012-09-01

    We report on the case of a 2-year-old girl recently diagnosed with Methylenetetrahydrofolate reductase (MTHFR) deficiency who originally presented in the neonatal period with a distinctive rash. At 11 weeks of age she developed seizures, she had acquired microcephaly and developmental delay. The rash deteriorated dramatically following commencement of phenobarbitone; both rash and seizures abated following empiric introduction of pyridoxine and folinic acid as treatment of possible vitamin responsive seizures. We postulate that phenobarbitone in combination with MTHFR deficiency may have caused her rash to deteriorate and subsequent folinic acid was helpful in treating the rash and preventing further acute neurological decline as commonly associated with this condition.

    A study of ticks associated with wild animals was carried out from September 1996 to April 1998 at the Fazenda Alegria (21,000 ha), in the Nhecolândia Pantanal, State of Mato Grosso do Sul, Brazil, a sunken plain bordering the upper Paraguay river, located 19 x 08'S; 56 x 46'W. A total of 81 wild animals (13 species, 6 orders) were captured with the aid of nets, and ticks were found on 63 (78%). Tick species identified included Boophilus microplus (Canestrini), Amblyomma cajennense (F.), A. parvum (Aragão), A pseudoconcolor (Aragão), A. scalpturatum (Neumann), A. nodosum (Neumann), A. ovale (Koch), and A. tigrinum (Koch). Dragging from grasslands (campos) yielded negative results compared to the high concentration of ticks, mainly nymphs, that were collected from leaves in the forests (capão). Predominance of immature instars (Amblyomma genera) was observed in the end of winter (August-September). Ticks were associated mainly with coatis, deer (Mazama gouazoubira) and anteater, and these animals may play a role in the epidemiology of tick-transmitted pathogens in the Pantanal if one considers their co-existence with local domestic animals.

    Full Text Available History of present illness: A 20-year-old female on day nine of amoxicillin for a recent diagnosis of pharyngitis presented to the emergency department with a complaint of rash for two days. The patient’s clinical course started two weeks prior and included fever, tonsillar exudates, and fatigue. Initial vitals were temperature of 37.6oC, blood pressure 122/82, heart rate 135, respiratory rate 18, and oxygen saturation 100% on room air. Significant findings: Her physical exam was significant for bilateral tonsillar exudates, cervical lymphadenopathy, and a morbilliform rash that included the palms (Figure 1-4. Laboratory testing was significant for white blood cell (WBC count of 16.5 thous/mcl with an elevation in absolute lymphocytes of > 10 thous/mcl. The monospot and EBV (Epstein-Barr virus panel were positive. Discussion: Infectious mononucleosis (IM is a clinical syndrome characterized by a triad of fever, tonsillar pharyngitis, and lymphadenopathy, and is most commonly associated with primary Epstein-Barr virus (EBV infection.1,2 The incidence of IM in the United States is 500 cases/100,000 person-years, with the highest incidence between ages 15 to 24 years.1 EBV transmission occurs predominantly through exposure to infected saliva3, with an incubation period of 30 – 50 days.1 The majority of patients with IM recover without apparent sequelae and most clinical and laboratory findings resolve by 1 month after diagnosis. Cervical adenopathy and fatigue may resolve more slowly ( > 6 months for fatigue.4,5 IM may be associated with several acute complications including splenic rupture (0.5 – 1% and airway obstruction (1%.6 A morbilliform rash occurs in up to 95% of patients with IM who are treated with beta-lactam antibiotics for presumed group A streptococcal infection.1 Diagnosis is typically made in the setting of the clinical syndrome combined with laboratory test to detect antibodies to certain EBV-associated antigens.7 Primary EBV

    Infants exhibit many skin rashes. Erythema toxicum neonatorum presents as erythematous macules, papules, and pustules on the face, trunk, and extremities; it typically resolves spontaneously within 1 week. Neonatal acne presents as comedones or erythematous papules on the face, scalp, chest, and back. Infantile acne is similar but starts after the neonatal period. Both conditions typically resolve spontaneously; failure to resolve within 1 year warrants evaluation for androgen excess. Neonatal cephalic pustulosis is an acne variant caused by hypersensitivity to Malassezia furfur. It is typically self-limited, but severe cases are managed with topical ketoconazole. Miliaria and milia are caused by sweat retention and present as tiny vesicles or papules; they resolve spontaneously. Contact diaper dermatitis is managed by keeping the diaper area clean and with open air exposure. Diaper dermatitis due to Candida albicans is managed with topical antifungals. Seborrheic dermatitis causes scaling on the scalp. Management involves shampooing and removing scales with a soft brush after applying mineral oil or petrolatum; severe cases are managed with tar or ketoconazole shampoo. Atopic dermatitis is related to food allergy in approximately one-third of children. Food allergy can be confirmed with oral food challenges or skin prick tests. Management includes elimination of irritants and triggers and use of low-potency topical steroids.

    Measles is a major cause of infant mortality in third world countries, leading to approximately one million deaths each year. The WHO aims to globally eradicate measles virus at the beginning of the next century, which will need a major effort in particular in countries like Sudan. To achieve goal epidemiological studies I am needed to estimate the magnitude of the problem for which accurate diagnostic test are needed. We therefore conducted a study in El hag Yousif area (population 500 000) in Khartoum North where measles is prevalent despite vaccination effort by EPI. We studied the accuracy of the WHO criteria for clinical diagnosis in comparison with laboratory diagnosis during a one-year period. A total of 145 under five suspected measles cases were identified by active, case finding and examined. 111 cases fully complied with the WHO criteria for diagnosis of clinical measles. Out of 103 clinical measles cases, tested using prototype rapid measles test IgM Elisa and Pcr, 77(75%) were measles positive. A battery of virus test was run on 21 sera out of the 26(25%) measles negatives: Herpes virus-6, Epstein-Bar and Dengue viruses were detected in five, one and one case, respectively. It was concluded that one out of every four cases diagnosed by the clinical as measles rash is probably caused by other viruses. (Author)

    Skin in the diapered area is continuously threatened by exposure to changes in pH levels, overhydration, mechanical friction, and fecal enzymes, making diaper rash a common occurrence among babies. Up to one third of infants may exhibit clinical symptoms of diaper rash at any time, and more than half of babies between the ages of 4 and 15 months develop diaper rash at least once in a 2-month period. Despite misperceptions that disposable diapers are related to an increase in diaper rash, the incidence of diaper dermatitis is on the decline, largely due to significant improvements in disposable diaper construction and materials. Modern-day disposable diapers are specifically designed to limit exposure to irritants in the diaper area, reduce overhydration, inhibit skin barrier compromise, and help maintain normal skin pH levels and have been thoroughly evaluated for safety and skin compatibility. © The Author(s) 2014.

  6. A Case Report of Rash at Peritoneal Dialysis Exit Site

    2015-11-01

    Full Text Available The International Society for Peritoneal Dialysis recommends the regular application of topical antibiotic-containing preparations in addition to a routine exit site care to reduce the risk of exit site infection (ESI. Among these prophylactic antimicrobial preparations, topical gentamicin is one of the widely used and effective antibiotics for prevention of ESI and peritonitis in peritoneal dialysis (PD patients. Overall, topical gentamicin is well tolerated; however, its use can be associated with the development of allergic contact dermatitis (ACD. We describe a first reported case of PD catheter exit site contact ACD due to topical gentamicin mimicking ESI. The patient in this report developed worsening violaceous in color and pruritic rash surrounding the PD catheter exit site that appeared 3 weeks after the initiation of gentamicin cream. The association between development of rash and initiation of topical gentamicin led to a suspicion of local reaction to gentamicin rather than ESI. Skin biopsy confirmed ACD. Discontinuation of the provoking agent and subsequent treatment with topical hydrocortisone application led to a resolution of the exit site rash. Any rash at a PD catheter exit site should be considered infectious until proven otherwise. However, it is important to be aware of noninfectious etiologies of exit site rashes as the treatment of these 2 conditions differs.

    Full Text Available Introduction. Varicella zoster virus (VZV encephalomyelitis with cranial nerve involvement is rare. Characteristically it is preceded by a rash and primarily presents in the immunocompromised. The spectrum of VZV neurologic disease is extensive and it is not uncommon to present without rash. We report the case of an elderly otherwise immunocompetent patient who presented with diverse manifestations of VZV CNS infection all occurring without rash. Case Report. A 78-year-old man presented with 1 week of progressive paraparesis and sensory loss, malaise, and fevers. MRI of the neuraxis demonstrated numerous enhancing lesions: intramedullary, leptomeningeal, pachymeningeal, and cranial nerves. Cerebrospinal fluid (CSF showed a white blood cell count of 420/μL with elevated protein (385 mg/dL. CSF VZV qualitative PCR was positive and CSF VZV immunofluorescence assay detected IgM antibody, confirming the diagnosis of VZV encephalomyelitis. Clinical and radiological improvement was observed after intravenous acyclovir treatment. Conclusion. This is a rare report of an immunocompetent patient with extensive VZV encephalomyelitis. We highlight the importance of considering this diagnosis even in the absence of the characteristic rash, and the potential risk of premature discontinuation of antiviral therapy once HSV has been excluded. Prompt recognition and treatment can dramatically reduce morbidity and mortality in patients.

    Diaper rash is one of the most common skin disorders of infancy and childhood. Some studies have shown that Shampoo-clay was effective to treat chronic dermatitis. Then, it is supposed that it may be effective in diaper rash; however, no published studies were found in this regard. This study aimed to compare the effects of Shampoo-clay (S.C) and Calendula officinalis (C.O) to improve infantile diaper rash. A randomized, double blind, parallel controlled, non-inferiority trial was conducted on 60 outpatient infants referred to health care centers or pediatric clinics in Khomein city and diagnosed with diaper rash. Patients were randomly assigned into two treatment groups including S.C group (n = 30) and C.O group (n = 30) by using one to one allocation ratio. The rate of complete recovery in three days was the primary outcome. Data was collected using a checklist and analyzed using t-test, Chi-square and Fisher's exact tests and risk ratio. Totally, 93.3% of lesions in the S.C group healed in the first 6 hours, while this rate was 40% in C.O group (P < 0.001). The healing ratio for improvement in the first 6 hours was 7 times more in the S.C group. In addition, 90% of infants in the SC group and 36.7% in the C.O group were improved completely in the first 3 days (P < 0.001). S.C was effective to heal diaper rash, and also had faster effects compared to C.O.

    One of the major routes of transmission of rickettsial and ehrlichial diseases is via ticks that infest numerous host species, including humans. Besides mammals, reptiles and amphibians also carry ticks that may harbor Rickettsia and Ehrlichia strains that are pathogenic to humans. Furthermore, reptiles and amphibians are exempt from quarantine in Japan, thus facilitating the entry of parasites and pathogens to the country through import. Accordingly, in the current study, we examined the presence of Rickettsia and Ehrlichia spp. genes in ticks associated with reptiles and amphibians originating from outside Japan. Ninety-three ticks representing nine tick species (genera Amblyomma and Hyalomma) were isolated from at least 28 animals spanning 10 species and originating from 12 countries (Ghana, Jordan, Madagascar, Panama, Russia, Sri Lanka, Sudan, Suriname, Tanzania, Togo, Uzbekistan, and Zambia). None of the nine tick species are indigenous in Japan. The genes encoding the common rickettsial 17-kDa antigen, citrate synthase (gltA), and outer membrane protein A (ompA) were positively detected in 45.2% (42/93), 40.9% (38/93), and 23.7% (22/93) of the ticks, respectively, by polymerase chain reaction (PCR). The genes encoding ehrlichial heat shock protein (groEL) and major outer membrane protein (omp-1) were PCR-positive in 7.5% (7/93) and 2.2% (2/93) of the ticks, respectively. The p44 gene, which encodes the Anaplasma outer membrane protein, was not detected. Phylogenetic analysis showed that several of the rickettsial and ehrlichial sequences isolated in this study were highly similar to human pathogen genes, including agents not previously detected in Japan. These data demonstrate the global transportation of pathogenic Rickettsia and Ehrlichia through reptile- and amphibian-associated ticks. These imported animals have potential to transfer pathogens into human life. These results highlight the need to control the international transportation of known and

    A 57-year-old right-handed woman with a history of left frontal lobe stroke had experienced episodes of language-expression difficulty followed by paraphasia lasting for approximately 30 seconds two years earlier. She was diagnosed with left frontal lobe epilepsy, and a lamotrigine regimen was initiated. This treatment had to be stopped five weeks after initiation because she developed a rash, and her drug lymphocyte stimulation test result was positive. Interestingly, she has since remained seizure free without requiring any antiepileptic medications. This adult case with a peculiar clinical course provides support for the hypothesis of immunomodulation process involvement in epilepsy, a phenomenon that was previously mainly seen in pediatric patients.

In this retrospective cohort study, clinical data were obtained in patients starting efavirenz or nevirapine between 2004-2010. Factors associated with rashes were explored using a multivariate Cox proportional hazards regression model. Of 3,999 patients who started NNRTI-based ART, 281 (7.0% experienced at least one episode of NNRTI-related rash with an incidence of 2.63 events/100 person-years, occurring in 10.2% and 5.6% of patients taking nevirapine and efavirenz respectively. Most rashes (94% were grade 1 or 2 and were reported a median of 2 months following initiation of ART. In multivariate analysis developing a rash was associated with nevirapine use (aHR 1.67, 95% CI 1.28-2.10, female gender (aHR of 1.39, 95% CI 1.01-1.92 and lower baseline CD4 counts (aHR 0.88, 95% CI 0.82-0.95 per 50 cells/mm³ increment. Patients with nevirapine-associated rash were 11 times more likely to discontinue treatment as patients with efavirenz-associated rash. In contrast to findings in other studies, NNRTI-associated rashes in Ghanaians appear more common in patients with lower baseline CD4 counts. Given the increased frequency of rashes with nevirapine and subsequent discontinuations in many patients, along with other treatment-limiting toxicities, this provides further impetus for the replacement of nevirapine by efavirenz as the first-line NNRTI treatment of choice in Africa.

    We examined the possible correlation between biotypes of Propionibacterium acnes, lipase activity, and rash degree in acne patients. Among 5 P. acnes biotypes, P. acnes biotype 3 (B3) was the most common, followed by P. acnes biotypes 1, 2 and 4; P. acnes biotype 5 was not found. P. acnes B3 was isolated from more severe skin rashes than those of the other biotypes. Production of propionic acid (PA) and butyric acid (BA) by P. acnes B3 was higher than those by the other P. acnes biotypes. As the rash degree in acne patients was more severe, the production of PA and BA elevated. Although only a few P. acnes strains were examined in the present study, P. acnes B3 had the highest lipase activity and might have the greatest influence on skin rash in acne patients.

    We describe a 26-year-old woman who presented with a nodular rash on the elbows following an insect bite. Two days later, she developed erythema nodosum. Both these lesions were treated symptomatically. One week later, she had purpura, abdominal pain, hematuria, and arthralgias, following which steroids were administered. Her investigations revealed only microscopic hematuria that disappeared with therapy. This pattern of sequential appearance of rash and a nodular morphology are both unique features not previously reported. PMID:24696039

    Herpes zoster is a common disorder characterized by a painful rash along a dermatome caused by reactivation of the varicella zoster virus (VZV). Muscle denervation injury from motor involvement is an uncommon phenomenon. Discordant distribution of the skin rash and motor nerve involvement, presenting as a skin rash in one body part and muscle weakness or pain from nerve involvement in another body part is an even more uncommonly reported finding. We present an unusual case of muscle denervation injury resulting from motor involvement of a peripheral nerve by VZV diagnosed by magnetic resonance imaging with cutaneous manifestations in a different dermatomal distribution. To the best of our knowledge, there has been no similar case reported in the English radiology literature. We suggest that whenever a radiologist notices MRI findings suggesting denervation injury and a cause not readily identified, VZV-related denervation injury should be included in the differential diagnosis, especially in an older immunocompromised patient.

    Full Text Available Legionella pneumophila is the most common cause of legionellosis and is one of the organisms causing atypical pneumonia. We report the presentation of disseminated intravascular coagulation (DIC and skin rash in a single case of severe Legionella pneumonia. The unique clinical presentation of a diffuse rash diagnosed as purpura fulminans and the unpredictable variations encountered during the diagnostic work-up of the case make this write-up crucial. This article synthesizes all reported cases of L. pneumonia associated with cutaneous manifestations as well as cases presenting with DIC. Furthermore, this manuscript illustrates the correlation between cutaneous and coagulopathic manifestations, and morbidity and mortality from L. pneumonia.

    Full Text Available Linear IgA disease of childhood (LAD also known as chronic bullous disease of childhood is an autoimmune disease with IgA deposition at the basement membrane zone leading to a vesiculobullous rash. It has a clinical appearance which frequently is described as resembling “strings of pearls” or rosette-like. Diagnosis is usually clinical but sometimes biopsy is required. Dapsone is widely considered to be the first line therapy in the treatment of LAD. A 5-year-old girl presented with 4-day history of a widespread painful rash and pyrexia. The rash transformed into painful blisters. A recent contact with chickenpox was present. She remained apyrexial but hemodynamically stable and was treated as chickenpox patient with secondary infection. Due to persistent symptoms after repeated attendance she was reviewed by Dermatology team and diagnosed with linear IgA disease also known as chronic bullous disease of childhood. This was based on the presence of blistering rash with rosette appearance and string of pearl lesions. The clinical features of LAD can be difficult to distinguish from more common skin infections. Benefiting from the experience of other multidisciplinary teams can sometimes be a game changer and can lead to the correct diagnosis and treatment.

    2014-12-01

    Full Text Available Parvovirus B19 can cause different skin rashes like maculopapular, erythematous, petechial, or purpuric lesions. In addition, parvovirus B19 can cause some important hematologic disorders like aplastic anemia, leukopenia, neutropenia, and thrombocytopenia. We report a child who was admitted to the hospital with petechial-purpuric rashes. On laboratory analysis, leukopenia and thrombocytopenia were found and serologic testing of parvovirus B19 IgM was determined to be positive. After the third day of hospitalization, the petechial-purpuric rashes began to decline and laboratory results were in the normal range. We think that the disease was parvovirus B19 infection. The patient was treated with only antipyretic drugs. On follow up, the clinical and laboratory findings had completely returned to normal. In conclusion, parvovirus B19 can cause clinical signs such as petechiae and purpura. Also, hematologic disorders may be a complication. Because of this, it should be considered in the differential diagnosis in patients with rash, thrombocytopenia, and leukopenia.

    To assess whether the cutaneous features in patients with dengue fever are associated with abnormal blood biochemistry, complications, and poor disease outcome. Forty five patients with dengue fever were identified at a medical center in Kaohsiung, Taiwan, from September to November 2014. All cases were exclusively caused by type 1 dengue virus. Patients were classified into two groups, based on the presence or absence of skin rash, and their rash was subclassified into maculopapular, morbilliform, and petechial types. Clinical symptoms, laboratory data, disease outcome, and complications were compared between the two groups. Thirty two patients with dengue fever developed skin rash (SP group, n = 32) while the rest of 13 did not (SN group, n = 13). The patient numbers in the maculopapular, morbilliform, and petechial group were 4, 21, and 7, respectively. The SP group was younger (P = 0.001), experienced more pruritus (P = 0.008) and more swollen palms/soles (P = 0.015) than the SN group. However, the SN group had greater genital mucosa involvement (P = 0.008), higher platelet transfusion rate (P = 0.003), and lower hemoglobin and hematocrit levels (P = 0.030) than the SP group. Patients with morbilliform lesions had a higher incidence of palm/sole swelling, less genital mucosal involvement, and a lower platelet transfusion rate than did patients with maculopapular or petechial lesions. Cutaneous manifestations provide an important clue to dengue fever. In patients with dengue fever, those with skin rash tend to have itching and swelling of the palms/soles, however, those without skin rash tend to have more complications and poor disease outcomes.

    Full Text Available OBJECTIVE: The clinical differential diagnosis of rash due to viral infections is often difficult, and misdiagnosis is not rare, especially after the introduction of measles and rubella vaccination. A study to determine the etiological diagnosis of exanthema was carried out in a group of children after measles vaccination. METHODS: Sera collected from children with rash who received measles vaccine were reported in 1999. They were analyzed for IgM antibodies against measles virus, rubella virus, human parvovirus B19 (HPV B19 using ELISA commercial techniques, and human herpes virus 6 (HHV 6 using immunofluorescence commercial technique. Viremia for each of those viruses was tested using a polimerase chain reaction (PCR. RESULTS: A total of 17 cases of children with exanthema after measles immunization were reported in 1999. The children, aged 9 to 12 months (median 10 months, had a blood sample taken for laboratory analysis. The time between vaccination and the first rash signs varied from 1 to 60 days. The serological results of those 17 children suspected of measles or rubella infection showed the following etiological diagnosis: 17.6% (3 in 17 HPV B19 infection; 76.5% (13 in 17 HHV 6 infection; 5.9% (1 in 17 rash due to measles vaccine. CONCLUSIONS: The study data indicate that infection due to HPV B19 or HHV 6 can be misdiagnosed as exanthema due to measles vaccination. Therefore, it is important to better characterize the etiology of rash in order to avoid attributing it incorrectly to measles vaccine.

  13. Risk of severe rash in cancer patients treated with EGFR tyrosine kinase inhibitors: a systematic review and meta-analysis.

    2016-12-01

    We performed a meta-analysis to evaluate the incidence and risk factors of severe rash associated with the use of EGFR tyrosine kinase inhibitors (TKIs). PubMed, EMBASE and oncology conference proceedings were searched for articles published till March 2016. A total of 18,309 patients from 37 randomized controlled trials were available for the meta-analysis. The overall incidence for severe rash was 6.6% (95% CI: 5.2-8.3%) among patients receiving EGFR-TKIs. The use of EGFR-TKIs significantly increased the risk of developing severe rash (risk ratio: 7.70; 95% CI: 5.79-10.23) in cancer patients. On subgroup analysis, the increased risk of severe rash was driven predominantly by drug type (p = 0.002). EGFR-TKIs significantly increase the risk of developing severe rash in cancer patients.

    Herpes zoster ophthalmicus, in which orbital symptoms and signs appear before the onset of a skin rash, is very rare. We experienced such a case and therefore report on it via magnetic resonance imaging. A 48-year-old man with pain and swelling of left eye and headache presented 2 days before onset of a zoster skin rash. On orbit-al MRI, edematous thickening of the left lateral rectus muscle with high signal intensity was revealed. After contrast injection, the lateral rectus muscle demonstrated heterogenous enhancement. Also, diffuse contrast enhancement was noted at left preseptal space, lacrimal gland and periorbital soft tissue. The man was treated with antiviral agents and prednisolone. Two weeks later, he recovered from the skin manifestations and most of the orbital manifestations except for the diplopia and restricted lateral movement.

    The application of carbon nanotubes (CNTs) as biomaterials is of wide interest, and studies examining their application in medicine have had considerable significance. Biological safety is the most important factor when considering the clinical application of CNTs as biomaterials, and various toxicity evaluations are required. Among these evaluations, carcinogenicity should be examined with the highest priority; however, no report using transgenic mice to evaluate the carcinogenicity of CNTs has been published to date. Here, we performed a carcinogenicity test by implanting multi-walled CNTs (MWCNTs) into the subcutaneous tissue of rasH2 mice, using the carbon black present in black tattoo ink as a reference material for safety. The rasH2 mice did not develop neoplasms after being injected with MWCNTs; instead, MWCNTs showed lower carcinogenicity than carbon black. Such evaluations should facilitate the clinical application and development of CNTs for use in important medical fields.

  16. Association between Rash and a Positive Drug Response Associated with Vinorelbine in a Patient with Primary Peritoneal Carcinoma

    2013-01-01

    Full Text Available Vinorelbine (Navelbine, VRL is commonly used for platinum-resistant ovarian cancer and has been shown to be effective in patients with recurrent primary peritoneal carcinoma. Of VRL’s major side effects, skin rash is uncommon, and, if it does occur, it is usually localized to site of injection. In this case report, a 71-year-old Hispanic female with primary peritoneal carcinoma received single agent VRL as fourth-line regimen, which she tolerated very well except for a skin rash related to VRL. The rash continued to progress throughout 6 cycles of VRL, and follow-up CT/PET scan demonstrated complete metabolic and radiological responses. We, therefore, believe that this rash was linked to VRL administration and correlated with response to therapy. Rash has been recognized as a useful surrogate marker with targeted agents such as cetuximab and erlotinib; to the best of our knowledge, this case report describes the first patient with a possible drug rash and its association with a positive outcome. This case report incites interest in further investigation of similar cases to support this observation, since there is a lack of reports of skin rash with VRL therapy.

    A 4-month-old infant was seen with hypokalemic metabolic alkalosis that was associated with prior application of liberal amounts of sodium bicarbonate (baking soda) to a diaper rash. After exclusion of other etiologies of the infant's acid-base disturbance, a complete resolution occurred following discontinuation of the baking soda applications. This case report provides a reminder of the significant side effects that may result from the excessive use of a seemingly harmless household substance.

    We have reviewed 47 drug rash with eosinophilia and systemic symptoms (DRESS) cases associated to strontium ranelate reported up to March 2011 to the Marketing Holder. The main signs were skin rash, fever, face oedema hypereosinophilia and liver involvement. For ten patients, persistence of DRESS symptoms was reported at the latest news obtained, and DRESS was identified as the direct cause of death in one case. The maximum incidence of DRESS associated with strontium ranelate was 1/24,112 [95 % CI (1/14,859; 1/42,194)] newly treated patients in France. Because DRESS is a severe drug reaction, the occurrence of a rash in a patient treated with strontium ranelate should lead to prompt and permanent treatment discontinuation. This study aims to describe cases of DRESS reported to the Marketing Authorisation Holder worldwide for patients receiving strontium ranelate by practitioner or by regulatory authorities. Spontaneously reported hypersensitivity events from the strontium ranelate pharmacovigilance database since marketing authorisation (2004) to March 2011 were reviewed by an expert committee. Cases of DRESS were classified as established, probable, possible or no DRESS according to expert judgement. National incidences of DRESS were estimated in relation to the number of newly treated patients. Up to March 2011, 325 cases of strontium ranelate-induced hypersensitivity events were assessed from which 47 DRESS cases were confirmed. Mean age was 68.7 years and besides skin rash, the main signs and symptoms were hypereosinophilia, liver involvement, fever and face oedema. Median time to skin reaction was 33.5 days after treatment start. Most patients (62 %) recovered at the time of reporting or were recovering. For ten patients, persistence of DRESS symptoms was reported at the latest news obtained. Relapses were observed in a single case. The mortality rate was 8.5 %. The maximum incidence of DRESS associated with strontium ranelate was 1/24,112 [95 % CI (1

    2017-10-01

    A 32-year-old man was admitted to our hospital with fever, chills, malaise, leukopenia, and a rash. About 3 weeks earlier, he'd had oral maxillofacial surgery and started a 10-day course of prophylactic amoxicillin/clavulanic acid. Fifteen days after the surgery, he developed a fever (temperature, 103° F), chills, arthralgia, myalgia, cough, diarrhea, and malaise. He was seen by his physician, who obtained a chest x-ray showing a lingular infiltrate. The physician diagnosed influenza and pneumonia in this patient, and prescribed oseltamivir, azithromycin, and an additional course of amoxicillin/clavulanic acid. Upon admission to the hospital, laboratory tests revealed a white blood cell count (WBC) of 3.1 k/mcL (normal: 3.2-10.8 k/mcL). The patient's physical examination was notable for lip edema, white mucous membrane plaques, submandibular and inguinal lymphadenopathy, and a morbilliform rash across his chest. Broad-spectrum antibiotics were initiated for presumed sepsis. On hospital day (HD) 1, tests revealed a WBC count of 1.8 k/mcL, an erythrocyte sedimentation rate of 53 mm/hr (normal: 20-30 mm/hr for women, 15-20 mm/hr for men), and a C-reactive protein level of 6.7 mg/dL (normal: leukopenia persisted and he had elevated levels of alanine transaminase ranging from 40 to 73 U/L (normal: 6-43 U/L) and aspartate aminotransferase ranging from 66 to 108 U/L (normal range: 10-40 U/L), both downtrending during his hospitalization. He also had elevated levels of antinuclear antibodies and anti-Smith antibody titers. A posterior-auricular biopsy was consistent with lymphocytic perivasculitis. The rash continued to progress, involving his chest, abdomen, and face. Bacterial and viral cultures remained negative and on HD 4, broad-spectrum antibiotics were discontinued.

    To study the characteristics of infants and children presenting with iatrogenic Cushing's Syndrome due to nappy rash ointments. The descriptive study was conducted at the Children's Hospital, Lahore, from April to September 2013, and comprised patients presenting with cushingoid features and history of using nappy rash ointments. Patients having Cushing's Syndrome due to causes other than iatrogenic were excluded and so were those taking oral or parenteral steroids due to skin allergy, renal or respiratory disease. Demographic data, history and examination of all patients were recorded on a proforma and results were analysed using SPSS 16. Of the total 18 patients, 13(72%) were girls and 5(27%) were boys. Eight (44.4%) patients were younger than 6 months, 6(33.3%) were between 6 months to 1 year, while 4(22.2%) were between 12 and 18 months of age. Clobetasol alone was the most frequently used agent responsible in 13(72%) cases. Duration of use of steroid ointment was as short as 3 weeks to as much as 1 year. All the patients were using disposable diapers. Ointment was prescribed by a doctor in 5(27%) cases and self-prescribed (relative or neighbour) in 13(72%). Self-medication and prolonged use of potent steroid ointments are major contributors in development of iatrogenic Cushing's Syndrome in infants and children. Younger age, female gender and use of disposable diapers were other important predisposing factors.

    Full Text Available Patients who present with papular rashes have a wide differential diagnosis particularly in the setting of immune compromise. A 30-year-old male diagnosed with HIV since 2009, never on antiretroviral therapy, with a nadir CD4 count of 333 cells/mm3 and a current viral load of 44,300 copies/mL, presented with a diffuse monomorphic papular eruption that began on his trunk and extremities and subsequently spread to the penis and scrotum, sparing the distal acral sites. A thorough infectious workup revealed a positive rapid plasma reagin (RPR and varicella IgM and IgG antibodies. Interestingly, the patient had been diagnosed and treated for syphilis in the past with a recent downtrending RPR drawn prior to hospitalization. Repeat RPR was elevated and a preliminary histopathology report demonstrated folliculocentric inflammation with lymphocytes, plasma cells, and polymorphonuclear leukocyte predominance supported the diagnosis of syphilis. After receiving intramuscular penicillin G benzathine, he developed intermittent fevers and new papules. Intravenous (IV acyclovir was initiated for presumed disseminated varicella given his positive varicella-zoster virus IgM and IgG. However, final pathology results revealed a large spirochete burden. The fevers and rash progression were attributed to the development of a Jarisch-Herxheimer reaction. IV acyclovir was discontinued and he completed a course of intramuscular penicillin G benzathine. He was also given a course of doxycycline for rectal chlamydia which was diagnosed during hospitalization.

Physical examination demonstrated crusting of the scalp, erythematous papules with surrounding petechiae on the lower abdomen, and an intraoral palatal ulcer. Further imaging demonstrated bone involvement. Histopathologic examination of involved skin and the intraoral ulcer demonstrated epithelioid histiocytes with “coffee bean-shaped” nuclei, staining positive for CD1a and langerin by immunohistochemistry, consistent with Langerhans cell histiocytosis (LCH. LCH is a disease entity of unknown etiology characterized by histiocytic proliferation that most commonly presents in young children. The cutaneous findings of LCH include a seborrheic dermatitis-like and/or red-brown papular eruption. Intraoral examination is crucial as oral mucosal and maxillofacial skeletal disease can also be seen in LCH. When a child presents with a recalcitrant seborrheic dermatitis-like eruption or chronic diaper rash, the clinician should be alerted to the possibility of LCH. Timely recognition and diagnosis of LCH is important for oncologic referral, evaluation, and treatment.

    Full Text Available A 25-year-old otherwise healthy male presented with new-onset odynophagia, rash, and orogenital ulcers. Despite treatment with antibiotics for presumed bacterial pharyngitis, the patient remained symptomatic, with abnormal vital signs and laboratory values. Upon dermatology consultation and histopathologic correlation, he was diagnosed with Behçet disease. Behçet disease is a rare rheumatologic condition that presents with recurrent oral ulcers and varying degrees of ophthalmic, neurologic, cardiac, and vascular disease. Given its protean nature, the treatment of Behçet disease is tailored to the patient's presentation and severity of organ involvement. Following treatment with colchicine and prednisone, the patient's symptoms improved rapidly.

    Full Text Available Purpura, particularly when accompanied by fever, is a worrisome finding in children. Acute hemorrhagic edema of infancy (AHEI is a benign type of small-vessel leukocytoclastic vasculitis that presents with progressive purpura and has an excellent prognosis. Patients with AHEI present with large, target-like purpuric plaques affecting the face, ear lobes, and extremities. While the rapid onset of these skin findings can be dramatic, the child with AHEI is usually well appearing with reassuring laboratory testing. We describe a case of a previously healthy 8-month-old female who presented with progressive purpura in a nondependent distribution, low-grade fevers, and extremity swelling. An extensive workup was performed prior to making the diagnosis of AHEI. Coronavirus was implicated as the likely triggering pathogen, and the patient suffered a recurrence of purpuric rash and swelling several weeks after her initial presentation.

    Chikungunya fever (CHIK-F) has been increasingly documented among Western travelers returning from areas with chikungunya virus transmission, which are also popular tourist sites. We present three Israeli travelers who developed fever, maculopapular rash and long-standing arthralgias while visiting northern Indian states not known to be involved in the chikungunya fever epidemic. We also present an epidemiological review of the chikungunya epidemic over the past decades. Rare systemic manifestations of this disorder, like catastrophic antiphospholipid syndrome (CAPS) and adult-onset Still's syndrome, are discussed. The present era of international travel poses a new diagnostic and epidemiologic challenge that demands increased awareness to the possibility of an exotic tropical infectious disease.

    Background. Bilateral reduction mammoplasty is a common plastic surgery procedure that can be complicated by unfavorable scar formation along incision sites. Surgical adhesives can be utilized as an alternative or as an adjunct to conventional suture closures to help achieve good wound tension and provide an adequate barrier with excellent cosmesis. The recently introduced DERMABOND PRINEO Skin Closure System Skin Closure System combines the skin adhesive 2-octyl cyanoacrylate with a self-adhering polyester-based mesh. Proposed benefits of wound closure with DERMABOND PRINEO Skin Closure System, used with or without sutures, include its watertight seal, easy removal, microbial barrier, even distribution of tension, and reduction in wound closure time. Although allergic reactions to 2-octyl cyanoacrylate have been reported, few allergic reactions to DERMABOND PRINEO Skin Closure System have been noted in the literature. This case series describes three patients who experienced an allergic reaction to DERMABOND PRINEO Skin Closure System after undergoing elective bilateral reduction mammoplasties at our institution to further explore this topic. Methods. Retrospective chart review of bilateral reduction mammoplasty patients who received DERMABOND PRINEO Skin Closure System dressing at our institution was performed. Results. Three patients were identified as having a rash in reaction to DERMABOND PRINEO Skin Closure System after bilateral reduction mammoplasty. All three patients required systemic steroid treatment to resolve the rash. One patient was identified as having a prior adhesive reaction. Conclusions. DERMABOND PRINEO Skin Closure System has demonstrated its efficacy in optimizing scar healing and appearance. However, as we demonstrate these three allergic reactions to DERMABOND PRINEO Skin Closure System, caution must be utilized in its usage, namely, in patients with a prior adhesive allergy and in sites where moisture or friction may be apparent.

    Coxsackie viruses are enteroviruses most common in children. Coxsackie B viral infections often present with biphasic fever, headache, pharyngitis, nausea/vomiting, diarrhea and a maculopapular rash that spares the palms and soles. These clinical features may be present in other viral infections. We present a case of a hospitalized adult with rash and fever with highly elevated ferritin levels later found to be due to Coxsackie B5. We believe this is the first case of Coxsackie B infection with otherwise unexplained highly elevated ferritin levels.

    Juvenile dermatomyositis (JDM) is the most common form of idiopathic inflammatory myopathy in children. While outcomes are generally thought to be good, persistence of skin rash is a common problem. The goal of this study was to describe the development of clinical treatment plans (CTP) for children with JDM characterized by persistent skin rash despite complete resolution of muscle involvement. The Childhood Arthritis and Rheumatology Research Alliance, a North American consortium of pediatric rheumatologists and other healthcare providers, used a combination of Delphi surveys and nominal group consensus meetings to develop CTP that reflected consensus on typical treatments for patients with JDM with persistent skin rash. Consensus was reached on patient characteristics and outcome assessment. Patients should have previously received corticosteroids and methotrexate (MTX). Three consensus treatment plans were developed. Plan A added intravenous immunoglobulin (IVIG) if it was not already being used. Plan B added mycophenolate mofetil, while Plan C added cyclosporine. Continuation of previous treatments, including corticosteroids, MTX, and IVIG, was permitted in plans B and C. Three consensus CTP were developed for use in children with JDM and persistent skin rash despite complete resolution of muscle disease. These CTP reflect typical treatment approaches and are not to be considered treatment recommendations or standard of care. Using prospective data collection and statistical methods to account for nonrandom treatment assignment, it is expected that these CTP will be used to allow treatment comparisons, and ultimately determine the best treatment for these patients.

    "Impulsivity" has been consistently identified as a key personality predictor of alcohol-related problems and subsequent alcohol use disorder. Multiple prior studies have demonstrated impulsivity is an individual difference factor that strengthens the effects of some risk factors, such as alcohol consumption and depressive symptoms, on alcohol problems. However, recent research indicated common measures of impulsivity actually reflect multiple dispositions toward rash action, and that alcohol problems were most consistently related to one of those dispositions, negative urgency. Little research has examined how specific dispositions to rash action may act as putative moderators of other risk factors for alcohol problems. The goal of the current study was to test which dispositions to rash action moderated the effects of concurrent alcohol use or depressive symptoms on alcohol problems. Using a large cross-sectional sample of college students (n = 573), the current study utilized semicontinuous regression models, which allow prediction of both the likelihood and level of alcohol problems. Negative urgency was found to be the main predictor of alcohol problems, above and beyond other dispositions to rash action, which replicates prior research. However, each of the other dispositions exhibited risk-enhancing effects on the relations between either depressive symptoms or alcohol use and concurrent alcohol problems. Specifically, lower levels of premeditation enhanced the association between depressive symptoms and alcohol problems, while lower perseverance and higher sensation seeking were related to more alcohol problems at higher levels of alcohol use. Results suggest that multiple dispositions to rash action were related to problematic alcohol use both directly and via their interaction with other risk factors. (c) 2011 APA, all rights reserved.

    BACKGROUND Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome (CSS), is a rare vasculitis of unknown etiology. Most of the patients have a long history of asthma and then develop autoimmune inflammation of small and medium-sized blood vessels, with consequent reduction of blood flow to various organs and tissues. EGPA can cause disorders in multiple systems; the most seriously affected organs are the retina, kidney, brain, cardiovascular system, and skin. CASE REPORT The patient was hospitalized for high fever and skin rashes and then developed right upper abdominal pain, decreased visual acuity, coma, and convulsions. Laboratory investigations showed marked eosinophilia (9412/mm3). Following cholecystectomy, histopathological examination revealed a marked inflammatory cell infiltrate composed mainly of eosinophils. Retinal vasculitis and medium and peripheral vascular closure were confirmed by fundus fluorescence angiography (FFA). The coma and convulsions were controlled successfully by high-dose methylprednisolone. After gradual tapering of the methylprednisolone, the patient's blood count recovered to a normal level, and the other systematic disorders disappeared; however, she was left with irreversible blindness. CONCLUSIONS EGPA can cause eosinophilic cholecystitis, retinal vasculitis, and neuropathy in the short term and calls for effective treatments in order to avoid binocular blindness.

    Data comparing the cutaneous side effects of light emitting diode (LED) phototherapy (LP) and conventional phototherapy (CP) devices in jaundiced newborn infants are very limited. We investigated the incidence and extent of skin eruptions caused by different phototherapy devices in preterm infants who are more prone to neonatal jaundice. This prospective, randomized controlled trial was conducted in the neonatal intensive care unit (NICU) of Hacettepe University Ihsan Dogramaci Childrens' Hospital in Ankara, Turkey. Preterm infants without skin lesions before and requiring phototherapy in the first week of life were included in the study. The infants were randomly assigned to receive CP or LP and were monitored closely for skin eruptions during phototherapy. Fifty-eight infants were included in the study: 25 (43.1%) received CP while 33 (56.9%) received LP. The duration of phototherapy was similar in the two groups (30.4 ± 9.6 hours and 31.8 ± 15.6 hours, respectively). Baseline and control bilirubin levels were similar for the two groups (p = 0.101 and p = 0.105, respectively). The frequency of skin eruptions was 36% in the CP group and 33% in the LP group (p = 0.83). The skin eruptions were macules in 13 (22.4%), papules in 5 (8.6%), and maculopapular rashes in 2 (3.4%) infants.There were no differences in the incidence and extent of skin eruptions in preterm infants who received CP or LP. © 2013 Wiley Periodicals, Inc.

    Hand-foot-and-mouth disease (HFMD) is a common cause of viral rash in children with classic skin findings which are easily recognized by pediatricians. Recently, several atypical cutaneous manifestations of HFMD have been described. Awareness of these patterns may lead providers to appropriate diagnosis and management. This review also highlights the epidemiological patterns of more virulent strains and emerging research in disease prevention. Classic HFMD presents with tender lesions on the hands, feet, and oral mucosa. Atypical skin findings in HFMD may be seen in children with atopic dermatitis. These include 'eczema coxsackium', in which eczematous skin is superinfected with coxsackie virus, resembling herpes infection. Nail changes, such as shedding, may follow HFMD after a latency period. Enterovirus 71 is responsible for epidemic outbreaks of HFMD in Asia, with systemic manifestations and occasionally neurological sequelae. Research is underway to develop a vaccine which could curb epidemics, but for the present, supportive care and hygiene measures are the standard of care. Atypical manifestations of HFMD in children with atopic dermatitis may mimic herpetic superinfection. In a child presenting with nail changes, consider antecedent HFMD in the differential diagnosis. The mainstay of treatment for HMFD remains supportive care.

    In late 2004, NSW Health received several reports of a serious desquamating rash among clients of the methadone program. We sought to identify the extent and likely cause of this outbreak. We initiated active surveillance for cases throughout Australia, a survey of dosing points in NSW, and a case control study of clients receiving methadone syrup (MS) at two clinics. Between October 2004 and March 2005, 388 cases were identified, largely in NSW. The dosing point survey found almost all cases were clients prescribed MS (attack rate 4.5%). In multivariate analysis of data from dosing points that dispensed MS, use of take away doses or location of the dosing point in greater western Sydney were associated with illness. In the case control study, MS injection, use of street MS, high doses of MS, frequent takeaway doses, or use of benzodiazepines were associated with illness. Testing found no abnormality in associated batches of MS. Batches of MS temporally associated with the outbreak were quarantined from use and the outbreak subsided. While a direct causal link could not be established, available evidence suggests that a contaminant may have caused the outbreak. Epidemiological analyses are important for assessing concerns about product safety following marketing approval.

    2017-06-01

    Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a hypersensitivity reaction associated with a variety of drugs, mainly anticonvulsants, which is characterized by systemic symptoms and erythematous lesions, common to other toxicodermas. It is an uncommon clinical entity that requires a high suspicion by clinical staff given its varied initial presentation, and the fact that symptoms can overlap with those of other adverse cutaneous reactions to drugs. Without early diagnosis and appropriate treatment, mortality increases.We report the case of a 22-year-old patient with impaired neurodevelopment who received treatment with carbamazepine. Two months later he presented with general symptoms and skin erythematous lesions that began on his trunk. The patient received outpatient care with antihistamines and antipyretics without an appropriate response. His case progressed with increased skin lesions and systemic symptoms that met the diagnostic criteria for DRESS syndrome. He was hospitalized and received medical treatment according to recommended guidelines. The patient's condition improved as his symptoms and associated complications resolved. He was discharged with gradual clearing of the steroid therapy.

  19. Etiology of maculopapular rash in measles and rubella suspected patients from Belarus.

    Full Text Available As a result of successful implementation of the measles/rubella elimination program, the etiology of more and more double negative cases remains elusive. The present study determined the role of different viruses as causative agents in measles or rubella suspected cases in Belarus. A total of 856 sera sent to the WHO National Laboratory between 2009 and 2011 were tested for specific IgM antibodies to measles virus (MV, rubella virus (RV and human parvovirus B19 (B19V. The negatives were further investigated for antibodies to enterovirus (EV and adenovirus (AdV. Children of up to 3 years were tested for IgM antibodies to human herpesvirus 6 (HHV6. A viral etiology was identified in 451 (52.7% cases, with 6.1% of the samples being positive for MV; 2.6% for RV; 26.2% for B19V; 9.7% for EV; 4.6% for AdV; and 3.6% for HHV6. Almost all measles and rubella cases occurred during limited outbreaks in 2011 and nearly all patients were at least 15 years old. B19V, EV and AdV infections were prevalent both in children and adults and were found throughout the 3 years. B19V occurred mainly in 3-10 years old children and 20-29 years old adults. EV infection was most common in children up to 6 years of age and AdV was confirmed mainly in 3-6 years old children. HHV6 infection was mostly detected in 6-11 months old infants. Laboratory investigation of measles/rubella suspected cases also for B19V, EV, AdV and HHV6 allows diagnosing more than half of all cases, thus strengthening rash/fever disease surveillance in Belarus.

    This phase II, open-label, randomised study evaluated whether patients with metastatic pancreatic cancer receiving erlotinib/gemcitabine derived survival benefits from increasing the erlotinib dose. After a 4-week run-in period (gemcitabine 1000 mg m(-2) once weekly plus erlotinib 100 mg per day), patients with metastatic pancreatic cancer who developed grade 0/1 rash were randomised to receive gemcitabine plus erlotinib dose escalation (150 mg, increasing by 50 mg every 2 weeks (maximum 250 mg); n=71) or gemcitabine plus standard-dose erlotinib (100 mg per day; n=75). The primary end point was to determine whether overall survival (OS) was improved by increasing the erlotinib dose. Secondary end points included progression-free survival (PFS), incidence of grade ⩾2 rash, and safety. Erlotinib dose escalation induced grade ⩾2 rash in 29 out of 71 (41.4%) patients compared with 7 out of 75 (9.3%) patients on standard dose. Efficacy was not significantly different in the dose-escalation arm compared with the standard-dose arm (OS: median 7.0 vs 8.4 months, respectively, hazard ratio (HR), 1.26, 95% confidence interval (CI): 0.88-1.80; P=0.2026; PFS: median 3.5 vs 4.5 months, respectively, HR, 1.09, 95% CI: 0.77-1.54; P=0.6298). Incidence of adverse events was comparable between randomised arms. The erlotinib dose-escalation strategy induced rash in some patients; there was no evidence that the higher dose translated into increased benefit.

    To examine the tumor-promoting effect of troglitazone (TRG), a novel thiazolidinedione insulin-sensitizing agent, on splenic hemangiosarcomas in rasH2 mice, histopathological and molecular analyses were performed in the spleen of female rasH2 mice fed a diet containing 6,000 or 0 ppm TRG for 16 weeks after 1,000 or 0 mg/kg urethane (UR) initiation. Histopathologically, splenic hemangiosarcomas were observed in the UR-alone and UR+TRG groups, but there was no significant difference in the incidence of splenic hemangiosarcomas between the UR-alone and UR+TRG groups. There were increasing tendencies in the number of positive cells for anti-PCNA antibody and gene expression in the UR+TRG group, but such a change was not statistically significant as compared to that in the UR-alone group. The gene expressions of VEGF, VEGFR1, VEGFC, VEGFR2 and Tie2 related to angiogenesis; c-fos related to MAPK cascade activation; and cyclin D1 related to cell cycle in the UR-alone and UR+TRG groups were significantly higher than those in the untreated control group. However, only the Tie2 gene in the UR+TRG group was significantly increased as compared to that in the UR-alone group. These results suggest that the vascular tumor-promoting activity of TRG in rasH2 mice is extremely low in the present experimental condition and a part of the gene related to angiogenesis probably contributes to the promotion of splenic hemangiosarcomas in rasH2 mice given TRG.

In clinical trials, rash was common, although severe rash was infrequent. To examine rash in patients with MDS treated with lenalidomide in the real world, the Celgene Global Drug Safety database was analyzed and compared with clinical trials.Materials and methods: Adverse event reports in the post-marketing setting and in the MDS-003/004 clinical trials were analyzed by action taken with lenalidomide, seriousness/grade, time to onset, and treatment duration.Results: Globally, 16,942 reports representing 36,793 adverse events from the post-marketing setting were submitted to the Global Drug Safety database between December 27, 2005 and June 13, 2013. Most rash adverse events were non-serious (Global Drug Safety database, 91% or grade 1/2 (MDS-003/004 trials, 87%–93%. Unexpectedly, rash, occurring at a median of 9 days after treatment initiation, was the leading cause of permanent discontinuation of lenalidomide. Seventy-two percent of non-serious rash adverse events led to early permanent discontinuation within two cycles, while in the MDS-003/004 pivotal clinical trials, only 2%–3% of rash adverse events led to permanent discontinuation.Conclusion: Non-serious rash was the most common reason for permanent discontinuation of lenalidomide in real-world settings. Managing lenalidomide-related rash using published recommendations might improve treatment duration and optimize patient outcomes. Keywords: adverse events, safety, post-marketing setting 

  3. Neisseria lactamica Causing a Lung Cavity and Skin Rash in a Renal Transplant Patient: First Report from India

    Full Text Available Neisseria lactamica, a commensal, has been very rarely reported to cause diseases in immunocompromised hosts. In medical literature, there is only one report of a cavitatory lung lesion caused by it. The patient was a kidney transplant recipient. Neisseria lactamica was found to be the cause of his pulmonary cavity and a desquamating rash on feet. With the rapidly spreading medical advance, more and more patients are getting organ transplants, so the population of immunocompromised people is on the rise.

    Pseudomonas oryzihabitans is a Pseudomonas bacterial organism rarely implicated in human infections. The bacterium has been isolated in a few reported cases of neurosurgical infections and patients with end-stage cirrhosis, sickle cell disease, and community-acquired urinary tract infections. Limited information exists in developing countries, however, because of the lack of advanced microbiological tools for identification and characterization of this bacterium. This case report describes the isolation of a rare Pseudomonas bacterium in a patient presenting with sepsis and skin infection. A 1-year-old girl was presented to a hospital in the northeastern part of Ghana with a 1-week history of pustular rashes on her scalp and neck, which occasionally ruptured, along with discharge of yellowish purulent fluid. The child is of Mole-Dagbon ethnicity and hails from the northern part of Ghana. Pseudomonas oryzihabitans was identified in the patient's blood culture using the 16S ribosomal deoxyribonucleic acid sequencing technique. The rash on the patient's scalp and skin resolved after continuous treatment with gentamicin while her condition improved clinically. This finding suggests the potential of this bacterium to cause disease in unsuspected situations and emphasizes the need to have evidence for the use of the appropriate antibiotic in clinical settings, particularly in rural settings in Africa. It also brings to the fore the unreliability of conventional methods for identification of Pseudomonas bacteria in clinical samples and thus supports the use of 16S ribosomal deoxyribonucleic acid in making the diagnosis.

    Purpose: To evaluate the severity of cetuximab-induced skin rash and its correlation with clinical outcome and late skin toxicity in patients with head and neck squamous cell carcinoma treated with chemoradiation therapy and cetuximab. Methods and Materials: Analysis included patients who received loading dose and ≥1 cetuximab dose concurrent with definitive chemoradiation therapy (70 Gy + cisplatin) or postoperative chemoradiation therapy (60-66 Gy + docetaxel or cisplatin). Results: Six hundred two patients were analyzed; 383 (63.6%) developed grade 2 to 4 cetuximab rash. Patients manifesting grade 2 to 4 rash had younger age (P<.001), fewer pack-years smoking history (P<.001), were more likely to be males (P=.04), and had p16-negative (P=.04) oropharyngeal tumors (P=.003). In univariate analysis, grade 2 to 4 rash was associated with better overall survival (hazard ratio [HR] 0.58, P<.001) and progression-free survival (HR 0.75, P=.02), and reduced distant metastasis rate (HR 0.61, P=.03), but not local-regional failure (HR 0.79, P=.16) relative to grade 0 to 1 rash. In multivariable analysis, HRs for overall survival, progression-free survival, distant metastasis, and local-regional failure were, respectively, 0.68 (P=.008), 0.85 (P=.21), 0.64 (P=.06), and 0.89 (P=.48). Grade ≥2 rash was associated with improved survival in p16-negative patients (HR 0.28 [95% confidence interval 0.11-0.74]) but not in p16-positive patients (HR 1.10 [0.42-2.89]) (P=.05 for interaction). Twenty-five percent of patients with grade 2 to 4 acute in-field radiation dermatitis experienced grade 2 to 4 late skin fibrosis, versus 14% of patients with grade 0 to 1 acute in-field radiation dermatitis (P=.002). Conclusion: Grade 2 to 4 cetuximab rash was associated with better survival, possibly due to reduction of distant metastasis. This observation was noted mainly in p16-negative patients. Grade 2 to 4 acute in-field radiation dermatitis was associated with higher rate of

    Cutaneous lupus erythematosus (CLE) may have prognostic implications for systemic lupus erythematosus (SLE). We aimed to determine the impact of discoid lupus erythematosus (DLE) and malar rash on SLE disease activity. Data were analyzed from the Toronto Lupus Clinic prospective cohort study. We compared SLE patients with active DLE or malar rash at SLE diagnosis to SLE patients who never developed CLE. Outcomes were assessed at one and five years, including Adjusted Mean Systemic Lupus Erythematosus Disease Activity Index 2000 (AMS). A total of 524 SLE patients (284 without CLE, 65 with DLE, and 175 with malar rash) were included. Mean AMS scores in patients without CLE at one and five years were 5.96 ± 5.06 and 4.00 ± 3.52, which did not differ significantly from scores at one (6.93 ± 5.31, p = 0.17) and five years (4.29 ± 2.62, p = 0.63) in the DLE group. In patients with malar rash, AMS scores at one (8.30 ± 6.80, p < 0.001) and five years (5.23 ± 3.06, p = 0.004) were higher than controls without CLE. Malar rash may be a marker of more severe systemic disease over time, while DLE has no significant impact on general SLE disease activity. © The Author(s) 2015.

    Full Text Available Background: Pityriasis rosea is an acute disseminated rash of unknown etiology and prolonged duration, characterized by erythematous- squamous plaques. Despite having an ostentatious clinical picture for both the patient and family, it is self-limited and usually resolves without sequelae. Pityriasis rosea is often erroneously diagnosed as mycosis and given unnecessary treatment. Objective: To describe the clinical and demographical features of pity- riasis rosea in a group of Mexican pediatric patients. Patients and methods: Retrospective and descriptive study in which the clinical and demographic features of patients attended at the department of dermatology of the National Institute of Pediatrics with diagnosis of pityriasis rosea within a ten year period were analysed. Results: Thirty patients with pityriasis rosea, with a frequency of 3.6 per 1000 dermatological patients. Pityriasis rosea was more frequent in females with a ratio of 1.5 to 1 and a mean age of 10 years. More than half of the patients (56% had an atypical presentation, and biopsy was mandatory in 7 patients to establish the final diagnosis. Conclusions: The knowledge of the clinical features of pityriasis rosea by primary care physicians will prevent from unnecessary work-up and treatments.

    Adult onset Still's disease (AOSD) is a systemic auto-inflammatory condition of unknown etiology, characterized by high fever, an evanescent, salmon-pink maculopapular skin rash, arthralgia or arthritis and leukocytosis. AOSD can also present with atypical cutaneous manifestations, such as persistent pruritic coalescent papules or plaques and linear lesions that have highly distinctive pathological features and are usually associated with severe disease. Herein, we present a 31-year-old Brazilian man with both typical Still's rash and atypical persistent polymorphic cutaneous manifestations associated with severe systemic inflammatory response syndrome. Eosinophils that are consistently lacking in the AOSD-associated skin lesions were evident in the skin biopsy of the persistent atypical cutaneous manifestations and were either drug-related or AOSD-associated.

    The Kata-Rash arc fragment is an allochthonous thrust-bound body situated near Penjween, 100 km northeast of Sulymannia city, Kurdistan Region, within the Iraqi portion of the Zagros suture zone. It forms part of the suprasubduction zone 'Upper Allochthon' terranes (designated as the Gimo-Qandil Group), which is dominated by calc-alkaline andesite and basaltic-andesite, rhyodacite to rhyolite, crosscut by granitic, granodioritic, and dioritic dykes. Previously, rocks of the Kata-Rash arc fragment were interpreted as a part of the Eocene Walash volcanic group. However, SHRIMP zircon U-Pb dates on them of 108.1 ± 2.9 Ma (Harbar volcanic rocks) and 107.7 ± 1.9 Ma (Aulan intrusion) indicate an Albian-Cenomanian age, which is interpreted as the time of igneous crystallisation. The Aulan intrusion zircons have initial εHf values of + 8.6 ± 0.2. On a Nb/Yb-Th/Yb diagram, all Kata-Rash samples fall within the compositional field of arc-related rocks, i.e. above the mid-ocean-ridge basalt (MORB)-ocean island basalt (OIB) mantle array. Primitive-mantle-normalised trace-element patterns for the Kata-Rash samples show enrichment in the large ion lithophile elements and depletion in the high-field-strength elements supporting their subduction-related character.

    A patient with Parkinson's disease taking levodopa/carbidopa, selegiline, buproprion, aspirin and niacin had decreased rigidity and bradykinesia when his niacin dose was steadily escalated for treatment of high triglycerides, but ultimately the patient could not tolerate niacin because of severe nightmares and skin rash. If further research can reproduce this patient's initial beneficial experience while avoiding the adverse effects, niacin could be a useful adjunctive agent for Parkinson's disease, either population-wide or in a pharmacogenomically defined set of responders.

    Full Text Available Abstract Introduction Anti-neutrophil cytoplasmic antibody-associated vasculitis has been associated with many drugs and it is a relatively rare side effect of the antihypertensive drug hydralazine. The diagnosis and management of patients who have anti-neutrophil cytoplasmic antibody-associated vasculitis may be challenging because of its relative infrequency, variability of clinical expression and changing nomenclature. The spectrum of anti-neutrophil cytoplasmic antibody-associated vasculitis is wide and can be fatal. This case documents a 62-year-old woman who presented with hydralazine-induced anti-neutrophil cytoplasmic antibody-positive renal vasculitis with a puzzling cutaneous rash. Case presentation We report a rare case of hydralazine-induced anti-neutrophil cytoplasmic antibody-associated vasculitis in a 62-year-old Caucasian woman who presented with a vasculitic syndrome with a sore throat, mouth ulcers and otalgia after several months of constitutional symptoms. She then proceeded to develop a rash over her right lower limb. Clinically, the rash had features to suggest Sweet’s syndrome, but also had some appearances consistent with embolic phenomena and did not have the appearance of palpable purpure usually associated with cutaneous vasculitis. Differential diagnoses were hydralazine-associated Sweet’s syndrome, streptococcal-induced cutaneous eruption or an unrelated contact dermatitis. A midstream urine sample detected glomerular blood cells in the setting of anti-neutrophil cytoplasmic antibody-positive renal vasculitis and Streptococcus pyogenes bacteremia. A renal biopsy revealed a pauci-immune, focally necrotizing glomerulonephritis with small crescents. Her skin biopsy revealed a heavy neutrophil infiltrate involving the full thickness of the dermis with no evidence of a leucocytoclastic vasculitis, but was non-specific. She was initially commenced on intravenous lincomycin for her bloodstream infection and subsequently

    The presence of an aberrantly activated epidermal growth factor receptor (EGFR) in many epithelial tumors, due to its overexpression, activating mutations, gene amplification and/or overexpression of receptor ligands, represent the fundamental basis underlying the use of EGFR tyrosine kinase inhibitors (EGFR-TKIs). Drugs inhibiting the EGFR have different mechanisms of action; while erlotinib and gefitinib inhibit the intracellular tyrosine kinase, monoclonal antibodies like cetuximab and panitumumab bind the extracellular domain of the EGFR both activating immunomediated anti-cancer effect and inhibiting receptor function. On the other hand, interleukin-8 has tumor promoting as well as neo-angiogenesis enhancing effects and several attempts have been made to inhibit its activity. One of these is based on the use of the old sulfone antibiotic dapsone that has demonstrated several interleukin-8 system inhibiting actions. Erlotinib typically gives a rash that has recently been proven to come out via up-regulated keratinocyte interleukin-8 synthesis with histological features reminiscent of typical neutrophilic dermatoses. In this review, we report experimental evidence that shows the use of dapsone to improve quality of life in erlotinib-treated patients by ameliorating rash as well as short-circuiting a growth-enhancing aspect of erlotinib based on increased interleukin-8 secretion.

    Renbök phenomenon describes the inhibition of a lesion when a different one appears. We describe the first case of Renbök phenomenon occurring in a context of erythema migrans (EM) spared by an amoxicillin-induced skin rash and we also present a literature review. A 60-year-old patient was treated with amoxicillin for EM on the right knee and subsequently developed generalized erythema as a result of an antibiotic-induced skin rash, with sparing of the area previously affected by EM. Renbök phenomenon was diagnosed. In 1981, Cochran et al. first described a maculopapular drug reaction, which spared the sites of previous X irradiation for a tumor. Since then, nearly 40 cases have been reported, mostly describing patient with alopecia areata of the scalp with hair growth within plaques of psoriasis. One of the mechanisms suggested is a role played by cytokine cross-regulation in competition among distinct immune responses. We report the first case of Renbök phenomenon involving EM spared by a drug reaction. This phenomenon provides an insight into inflammatory response competition within a single patient.

    Lamotrigine is an antiepileptic drug used for the treatment of epilepsy, bipolar disorder and numerous off-label uses. The development of rash significantly affects its use. The most concerning of these adverse reactions is Stevens-Johnson syndrome/toxic epidermal necrolysis. We performed a systematic review of randomized controlled trials using lamotrigine as a monotherapy to quantify the incidence of cutaneous reactions, particularly Stevens-Johnson syndrome/toxic epidermal necrolysis. Of a total of 4,364 papers regarding lamotrigine, 122 studies met our inclusion and exclusion criteria. In total, 18,698 patients were included with 1,570 (8.3%) of patients experiencing an adverse dermatologic reaction. The incidence of Stevens-Johnson syndrome/toxic epidermal necrolysis was 0.04%.

    2015-02-01

    Mycoplasma pneumoniae infection is associated with extrapulmonary complications, including mucocutaneous eruptions. These eruptions, which have been termed either "Stevens-Johnson syndrome" or "erythema multiforme" in the literature, may differ from drug-induced Stevens-Johnson syndrome or viral-associated erythema multiforme. We sought to review the literature characterizing morphology and disease course of M pneumoniae-associated mucocutaneous disease. A comprehensive literature search identified 95 articles with 202 cases. Patients were often young (mean age: 11.9 years) and male (66%). Cutaneous involvement ranged from absent (34%), to sparse (47%), to moderate (19%). Oral, ocular, and urogenital mucositis was reported in 94%, 82%, and 63% of cases, respectively. Treatments included antibiotics (80%), systemic corticosteroids (35%), supportive care alone (8%), and/or intravenous immunoglobulin (8%). Complications included mucosal damage (10%), cutaneous scarring (5.6%), recurrence (8%), and mortality (3%). Mild cases may not have been published; thus this review may have a bias toward more severe disease. M pneumoniae-associated mucocutaneous disease has prominent mucositis and sparse cutaneous involvement, although cutaneous involvement varies. Because of the distinct morphology, mild disease course, and potentially important clinical implications regarding treatment, we propose a revision of the nomenclature system and suggest the term "Mycoplasma-induced rash and mucositis" for these cases.

    2016-03-01

    Skin rashes are infrequently encountered in the intensive care units, either as a result or as a cause of admission. The entities of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) form a spectrum of desquamating skin diseases that have multiple etiologies, the most common being drug-related reactions; very rarely, the cause may be cutaneous malignancies. We herein present a unique case of a 54-year-old male patient with psoriasis treated with methotrexate, who presented with a cellulitis-like clinical picture, then developed a severe progressive systemic inflammatory response syndrome, and progressed clinically to SJS, then TEN even after discontinuing the antibiotics and methotrexate. A skin biopsy demonstrated an aggressive and rapidly-progressing T-cell lymphoma. The present case highlights the necessity of skin biopsy when encountering SJS and TEN in the ICU in order to identify potentially treatable/controllable causes. Although it appeared reasonable to correlate TEN solely to medications, the skin biopsies clearly demonstrated an aggressive T-cell skin lymphoma. In a patient with a better general condition it may have been helpful to treat this malignancy. TEN is a life-threatening condition and skin biopsy is the cornerstone of diagnosis, despite the presence of multiple risk factors and the typical physical findings of a drug-induced reaction.

This study aimed to determine the incidences of hepatotoxicity and skin rashes within 4 weeks of initiation of cART containing 1 nNRTI plus 2 NRTIs.Between June, 2012 and November, 2015, all antiretroviral-naive HIV-positive adult patients initiating nNRTI-containing cART at 8 designated hospitals for HIV care were included in this retrospective observational study. According to the national HIV treatment guidelines, patients were assessed at baseline, 2 and 4 weeks of cART initiation, and subsequently every 8 to 12 weeks. Plasma HIV RNA load, CD4 cell count and aminotransferases were determined. The toxicity grading scale of the Division of AIDS (DAIDS 2014 was used for reporting clinical and laboratory adverse events.During the 3.5-year study period, 2,341 patients initiated nNRTI-containing cART: NVP in 629 patients, EFV 1,363 patients, and RPV 349 patients. Rash of any grade occurred in 14.1% (n = 331 of the patients. In multiple logistic regression analysis, baseline CD4 cell counts (per 100-cell/μl increase, adjusted odds ratio [AOR], 1.125; 95% confidence interval [95% CI], 1.031-1.228 and use of NVP (AOR, 2.443; 95% CI, 1.816-3.286 (compared with efavirenz were independently associated with the development of skin rashes.

    Phenolphthalein has carcinogenic activity, causing malignant lymphomas in B6C3F1 mice at a dietary dose of 3000 ppm in a 2-year carcinogenicity study and in heterozygous p53-deficient female mice at the same dose in a 6-month study. To examine whether phenolphthalein carcinogenic potential can be detected in male and female transgenic (Tg) mice carrying the human c-Ha-ras gene (rasH2 mice) and their wild-type littermates (non-Tg mice), a diet containing 3000, 6000 or 12000 ppm was given for 6 months. Unequivocal induction of neoplastic lesions was not apparent, suggesting that rasH2 mice are resistant to the induction of malignant lymphomas by the treatment of phenolphthalein.

    Eleven open multicentre studies were conducted to evaluate the efficacy of tioconazole cream 1% as a treatment for diaper rash with or without fungal (Candida) involvement, or impetigo in neonates and infants. In the dermal candidiasis/diaper rash group, 320 patients had either tioconazole (n = 220), a comparative imidazole (n = 43), or vehicle cream (n = 57) applied to the affected area twice daily. Twenty-one impetigo patients had only tioconazole cream 1% applied three times daily to lesions. The overall cure rate (patients with both clinical and mycological cure) at the end of treatment for tioconazole treated patients was 78%, for the comparative imidazole group it was 76% and for vehicle cream it was 39%. At the long-term follow-up evaluation approximately 6 weeks after treatment for patients with diaper rash, the overall cure rate was about the same in both tioconazole- and comparative imidazole-treated patients (87% and 90%, respectively), and 14% in patients using vehicle cream. Side-effects were coincident with disease symptoms and consisted primarily of erythema localized to the treatment area; they occurred in 5.4% (13/241) of the patients who received tioconazole and in 21% (9/43) of the patients who received comparative imidazole (econazole or miconazole). No side-effects were reported in this open study for the 57 patients who used vehicle cream. The results of these studies show that tioconazole cream 1% is safe and effective for the treatment of neonates and infants with dermal candidiasis, diaper rash and impetigo.

Several studies have shown that hangeshashin-to (TJ-14 might be useful for chemotherapy-induced diarrhea and oral mucositis. In this study, we investigated the prophylactic effects of TJ-14 for afatinib-induced diarrhea and oral mucositis and minocycline for afatinib-induced skin rash.Patients and methods: First- and second-generation epidermal growth factor receptor (EGFR-tyrosine kinase inhibitors have become the standard first-line treatment in patients with EGFR-mutated non-small cell lung cancer. The incidence of diarrhea was higher with afatinib than with gefitinib, and we conducted a single-arm Phase II study with afatinib. Patients who had previously undergone treatment with afatinib were ineligible. Both TJ-14 (7.5 g/day and minocycline (100 mg/day were administered simultaneously from the start of afatinib administration. The primary end point was the incidence of ≥ grade 3 (G3 diarrhea (increase of ≥7 stools/day over baseline during the first 4 weeks of treatment. The secondary end points were the incidence of ≥ G3 oral mucositis (severe pain interfering with oral intake and ≥ G3 skin toxicity (severe or medically significant but not immediately life-threatening.Results: A total of 29 patients (nine men and 20 women; median age, 66

  12. Not All Erythema Migrans Lesions Are Lyme Disease.

    Science.gov (United States)

    Goddard, Jerome

    2017-02-01

    Lyme disease is the number one arthropod-transmitted disease in the US, and one of the diagnostic criteria for the illness is development of an erythematous bull's-eye rash around a tick bite that may expand over time, hence the term erythema migrans. However, there are other erythema migrans-like rashes, such as those from a condition known as southern tick-associated rash illness. This article describes a patient with an erythema migrans-like lesion similar to that associated with Lyme disease, resulting from a bite by a nymphal-stage lone star tick, Amblyomma americanum. A tick removed from the center of an erythema migrans-like lesion in a patient was identified to species and then submitted to the Centers for Disease Control and Prevention for testing for the agent of Lyme disease, Borrelia burgdorferi. The patient was evaluated by an internist 7 weeks later. After another 3 weeks, the patient's blood was tested serologically for Lyme disease by American Esoteric Laboratories, Memphis, Tenn. Both the tick and human blood sample from this patient were negative for evidence of Lyme disease. Clinically, other than the erythema migrans-like lesion, the patient displayed no signs or symptoms consistent with Lyme disease. This case presents clinical, serological, and molecular evidence that erythema migrans lesions may occur after tick bites in patients and that these lesions may not be due to infection with the agent of Lyme disease.

    The Southern Ocean includes the only latitude band where the ocean circles the earth unobstructed by continental boundaries. This accident of geography has profound consequences for global ocean circulation, biogeochemical cycles, and climate. The Southern Ocean connects the ocean basins and links the shallow and deep limbs of the overturning circulation (Rintoul et al., 2001). The ocean's capacity to moderate the pace of climate change is therefore influenced strongly by the Southern Ocean's...

    1987-08-01

    A retrospective study of biopsies taken at three hospitals in Southern Ethiopia has been carried out to describe the cancer pattern in the Sidamo and Gamu Gofa regions. A histologically verified cancer diagnosis was recorded in 1154 patients. The bias that appear in the data are discussed. This includes aspects of hospital coverage, age and sex distribution and bias that arise from a lack of diagnostic facilities, especially to diagnose deep seated tumours. Taking these bias into consideration, the cancer pattern in Southern Ethiopia is outlined. Among men, hepatic carcinoma, lymphomas and superficial malignancies (skin cancers including melanomas and superficial soft tissue sarcomas) are the most common malignancies while among women, cervical, breast and ovarian cancers predominate. It is noted that most of the Kaposi's sarcomas recorded are from the Sidamo area. Hodgkin's disease and Burkitt's lymphoma are most common among childhood lymphomas, whereas non-Hodgkin lymphomas of other types dominate among adults. Cancer of the stomach is the second most common internal malignancy among both men and women.

  20. Epidemiological surveillance of low pathogenic avian influenza virus (LPAIV from poultry in Guangxi Province, Southern China.

    Directory of Open Access Journals (Sweden)

    Yi Peng

    Full Text Available Low pathogenic avian influenza virus (LPAIV usually causes mild disease or asymptomatic infection in poultry. However, some LPAIV strains can be transmitted to humans and cause severe infection. Genetic rearrangement and recombination of even low pathogenic influenza may generate a novel virus with increased virulence, posing a substantial risk to public health. Southern China is regarded as the world "influenza epicenter", due to a rash of outbreaks of influenza in recent years. In this study, we conducted an epidemiological survey of LPAIV at different live bird markets (LBMs in Guangxi province, Southern China. From January 2009 to December 2011, we collected 3,121 cotton swab samples of larynx, trachea and cloaca from the poultry at LBMs in Guangxi. Virus isolation, hemagglutination inhibition (HI assay, and RT-PCR were used to detect and subtype LPAIV in the collected samples. Of the 3,121 samples, 336 samples (10.8% were LPAIV positive, including 54 (1.7% in chicken and 282 (9.1% in duck. The identified LPAIV were H3N1, H3N2, H6N1, H6N2, H6N5, H6N6, H6N8, and H9N2, which are combinations of seven HA subtypes (H1, H3, H4, H6, H9, H10 and H11 and five NA subtypes (N1, N2, N5, N6 and N8. The H3 and H9 subtypes are predominant in the identified LPAIVs. Among the 336 cases, 29 types of mixed infection of different HA subtypes were identified in 87 of the cases (25.9%. The mixed infections may provide opportunities for genetic recombination. Our results suggest that the LPAIV epidemiology in poultry in the Guangxi province in southern China is complicated and highlights the need for further epidemiological and genetic studies of LPAIV in this area.

    2008-02-01

    Full Text Available Abstract Background Dermatological remedies make up at least one-third of the traditional pharmacopoeia in southern Italy. The identification of folk remedies for the skin is important both for the preservation of traditional medical knowledge and in the search for novel antimicrobial agents in the treatment of skin and soft tissue infection (SSTI. Our goal is to document traditional remedies from botanical, animal, mineral and industrial sources for the topical treatment of skin ailments. In addition to SSTI remedies for humans, we also discuss certain ethnoveterinary applications. Methods Field research was conducted in ten communities in the Vulture-Alto Bradano area of the Basilicata province, southern Italy. We randomly sampled 112 interviewees, stratified by age and gender. After obtaining prior informed consent, we collected data through semi-structured interviews, participant-observation, and small focus groups techniques. Voucher specimens of all cited botanic species were deposited at FTG and HLUC herbaria located in the US and Italy. Results We report the preparation and topical application of 116 remedies derived from 38 plant species. Remedies are used to treat laceration, burn wound, wart, inflammation, rash, dental abscess, furuncle, dermatitis, and other conditions. The pharmacopoeia also includes 49 animal remedies derived from sources such as pigs, slugs, and humans. Ethnoveterinary medicine, which incorporates both animal and plant derived remedies, is addressed. We also examine the recent decline in knowledge regarding the dermatological pharmacopoeia. Conclusion The traditional dermatological pharmacopoeia of Vulture-Alto Bradano is based on a dynamic folk medical construct of natural and spiritual illness and healing. Remedies are used to treat more than 45 skin and soft tissue conditions of both humans and animals. Of the total 165 remedies reported, 110 have never before been published in the mainland southern Italian

    Full Text Available Although world-systems theory was originally formulated with our modern economic system in mind (Wallerstein 1974, it was not long before archaeologists began to apply it to ancient societies. Archaeologists and world-system theorists alike both argued that Wallerstein had disregarded evidence of interconnected, hierarchical systems in prehistoric times (Schneider 1977; Chase-Dunn & Hall 1991, 1997; Kardulias 1999a. Pailes and Whitecotton (1979 were among the first to modify world-systems theory for use in pre-capitalist settings. Since then many archaeologists have looked at data and regions with a world-systems perspective in mind (e.g. Champion 1989; Bilde et al. 1993; Rowlands & Larsen 1987; Kardulias 1999a. Some have attempted to map Wallerstein's theory directly onto prehistory (Kohl 1979; Whitecotton & Pailes 1986; Ekholm & Friedman 1982. Others have found the world systems model heuristically useful but lacking the analytical power needed for their prehistoric cases (Blanton et al. 1981; Upham 1982; Plog 1983; Alcock 1993. Building on the assumption that ancient societies were not qualitatively, but only quantitatively, different from modern capitalist ones (Schneider 1977; Sherratt & Sherratt 1991, this study applies world systems theory to the Southern Aegean during the Middle and Late Bronze Age (ca. 2000-1550 BC.

  3. Erythema Migrans

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available History of present illness: A 28-year-old male presented to the emergency department with a chief complaint of two weeks of headache, chills, and numbness in his hands. He reported removing a tick from his upper back approximately two weeks ago, but did not know how long the tick had been embedded. His review of symptoms was otherwise unremarkable. Significant findings: On physical examination, an 8-cm non-raised, erythematous lesion with central clearing was noted on the right posterior thorax. A small scab was located at the center of the lesion with no evidence of retained tick. No other rashes were present. Discussion: Lyme disease is a tick-borne illness caused primarily by the spirochete Borrelia burgdorferi. Ticks must be attached for a minimum of 48 hours in order to transmit the spirochete.1 Erythema migrans (EM is the most common clinical manifestation of Lyme disease. EM is characterized by a slowly-expanding erythematous rash at the site of the tick bite, typically appearing between 7 and 14 days following tick attachment. Rashes range from 5cm to 30cm and may develop central clearing.2 EM must be differentiated from initial erythema at the site of the bite due to a reaction to tick saliva. The differential includes southern tick-associated rash illness, erythema multiforme, cellulitis, contact dermatitis, and tinea corporis. The presence of erythema migrans has a sensitivity of 69% and a specificity of 98% for Lyme disease.3 Serological testing is not indicated in patients with EM, as only about 30% will be seropositive at presentation.4 Treatment of early Lyme disease consists of doxycycline preferentially, or amoxicillin, or cefuroxime for 14 days.6 Recurrence of erythema migrans after a full course of antibiotics is most likely due to re-infection rather than relapse.7 Prognosis is excellent with antibiotic treatment; however, those in endemic areas are at high risk for re-infection.8

  16. Banking in southern Europe

    Directory of Open Access Journals (Sweden)

    Lazarević Žarko

    2014-01-01

    Full Text Available The nations discussed here (Italy, Spain, Portugal and Greece have in common - with the exception of Italy, that is - that they used to be on the margins of European economic and social developments. Only Italy succeeded in industrialising itself already prior to World War I. This fundamental trait also determined the developmental path of modern-era banking. Hereby, two important points in the course of development of banking in the Southern European countries need to be emphasised. To begin with, if the lands of the North-Western Europe were large capital exporters, then the South European nations were the importers of this capital. The role of foreign capital, i.e., foreign banks, was great and irreplaceable in the development of banking. The second element in common was a large role of state in the economy in general. Under the circumstances of underdeveloped entrepreneurial environment, the state, through its economic activities, would become the driving force of overall economic and social development. This was also or especially the case with banking. Role played by the state only began to diminish towards the end of the 1980s, in the course of the processes of deregulation and liberalisation both at the international level as well as within the then European Economic Community or subsequent European Union. Already during the preparatory processes prior to the admission into the European Economic Community, Spain, Greece and Portugal, and, however, Italy as well, but due to European Directives it had to abide by, began comprehensive processes of restructuring their national banking systems. Since the second half of the 1980s, banking systems were subjected to liberalisation, deregulation and privatisation.

  17. Treasures of the Southern Sky

    CERN Document Server

    Gendler, Robert; Malin, David

    2011-01-01

    In these pages, the reader can follow the engaging saga of astronomical exploration in the southern hemisphere, in a modern merger of aesthetics, science, and a story of human endeavor. This book is truly a celebration of southern skies.  Jerry Bonnell, Editor - Astronomy Picture of the Day The southern sky became accessible to scientific scrutiny only a few centuries ago, after the first European explorers ventured south of the equator. Modern observing and imaging techniques have since revealed what seems like a new Universe, previously hidden below the horizon, a fresh astronomical bounty of beauty and knowledge uniquely different from the northern sky. The authors have crafted a book that brings this hidden Universe to all, regardless of location or latitude. Treasures of the Southern Sky celebrates the remarkable beauty and richness of the southern sky in words and with world-class imagery. In part, a photographic anthology of deep sky wonders south of the celestial equator, this book also celebrates th...

  18. An Introduction: Around Southern Modernisms

    Directory of Open Access Journals (Sweden)

    Cunha Leal, Joana

    2016-07-01

    Full Text Available In this special issue you will find a discussion on southern modernisms stemming from an exploratory research project funded by the Portuguese Science Foundation (FCT between 2014 and 2015. As a project, southern modernisms had a theoretical and historiographical focus driven to discuss the resonances of the two words associated in its title, as well as the disquieting effect of their combination in the fields of visual arts and architecture. The first word – modernisms – stood against the standardized canon of modernism, thus bonding the research to the critical revision of that concept occurring in art history since the closing decades of the 20th century; the second word based the project in southern Europe, meaning that Portugal, Spain, Italy and Greece would set the ground for selecting case studies.

  13. Unprecedented emergency in Southern Africa.

    Science.gov (United States)

    1999-03-01

    Despite knowledge of better prevention strategies, AIDS continues to be an unprecedented emergency in southern Africa. Statistics show that in 1998, 1.4 million people between the ages of 15 and 49 in the 9 countries of southern Africa were infected, with nearly three-quarters of a million of these new infections occurring in South Africa. In addition, some 2 million people died of AIDS in sub-Saharan Africa in 1998 and millions of new infections are occurring every year. Factors such as the loneliness suffered by migrant laborers, the wars and armed conflicts in Rwanda, and the stigma of shame, silence, and denial associated with AIDS all generate fertile conditions for the spread of HIV in southern Africa. Overcoming silence and denial, and bringing AIDS out into the open, has been considered by some countries in southern Africa. In Botswana and South Africa, appeals for greater awareness and openness by the top leadership have been coupled with a decision to set up government funding and AIDS. The challenge now will be to translate these into effective prevention and care programs.

  16. Unprecedented Fires in Southern Africa

    Science.gov (United States)

    2002-01-01

    The fires that raged across southern Africa this August and September produced a thick 'river of smoke' over the region. NASA-supported studies currently underway on the event will contribute to improved air pollution policies in the region and a better understanding of its impact on climate change. This year the southern African fire season peaked in early September. The region is subject to some of the highest levels of biomass burning in the world. The heaviest burning was in western Zambia, southern Angola, northern Namibia, and northern Botswana. Some of the blazes had fire fronts 20 miles long that lasted for days. In this animation, multiple fires are burning across the southern part of the African continent in September 2000. The fires, indicated in red, were observed by the Advanced Very High Resolution Radiometer (AVHRR) instrument on board the NOAA-14 satellite. The fires generated large amounts of heat-absorbing aerosols (the dark haze), which were observed with the Earth Probe Total Ozone Mapping Spectrometer (TOMS) instrument. These observations were collected as part of a NASA-supported field campaign called SAFARI 2000 (Southern African Regional Science Initiative). The recent six-week 'dry-season' portion of this experiment was planned to coincide with the annual fires. SAFARI 2000 planners tracked the changing location of fires with daily satellite maps provided by researchers at NASA's Goddard Space Flight Center. 'Every year African biomass burning greatly exceeds the scale of the fires seen this year in the western United States,' says Robert Swap of the University of Virginia, one of the campaign organizers. 'But the southern African fire season we just observed may turn out to be an extreme one even by African standards. It was amazing how quickly this region went up in flames.' The thick haze layer from these fires was heavier than campaign participants had seen in previous field studies in the Amazon Basin and during the Kuwati oil fires

    Tannebaum, R D; Arnold, J L; De Negri Filho, A; Spadoni, V S

    2001-02-01

    Emergency medicine is developing rapidly in southern Brazil, where elements of both the Franco-German and the Anglo-American models of emergency care are in place, creating a uniquely Brazilian approach to emergency care. Although emergency medical services (EMS) in Brazil have been directly influenced by the French mobile EMS (SAMU) system, with physicians dispatched by ambulances to the scenes of medical emergencies, the first American-style emergency medicine residency training program in Brazil was recently established at the Hospital de Pronto Socorro (HPS) in Porto Alegre. Emergency trauma care appears to be particularly developed in southern Brazil, where advanced trauma life support is widely taught and SAMU delivers sophisticated trauma care en route to trauma centers designated by the state.

  18. Pteropods in Southern Ocean ecosystems

    Science.gov (United States)

    Hunt, B. P. V.; Pakhomov, E. A.; Hosie, G. W.; Siegel, V.; Ward, P.; Bernard, K.

    2008-09-01

    To date, little research has been carried out on pelagic gastropod molluscs (pteropods) in Southern Ocean ecosystems. However, recent predictions are that, due to acidification resulting from a business as usual approach to CO 2 emissions (IS92a), Southern Ocean surface waters may begin to become uninhabitable for aragonite shelled thecosome pteropods by 2050. To gain insight into the potential impact that this would have on Southern Ocean ecosystems, we have here synthesized available data on pteropod distributions and densities, assessed current knowledge of pteropod ecology, and highlighted knowledge gaps and directions for future research on this zooplankton group. Six species of pteropod are typical of the Southern Ocean south of the Sub-Tropical Convergence, including the four Thecosomes Limacina helicina antarctica, Limacina retroversa australis, Clio pyramidata, and Clio piatkowskii, and two Gymnosomes Clione limacina antarctica and Spongiobranchaea australis. Limacina retroversa australis dominated pteropod densities north of the Polar Front (PF), averaging 60 ind m -3 (max = 800 ind m -3) and 11% of total zooplankton at the Prince Edward Islands. South of the PF L. helicina antarctica predominated, averaging 165 ind m -3 (max = 2681 ind m -3) and up to >35% of total zooplankton at South Georgia, and up to 1397 ind m -3 and 63% of total zooplankton in the Ross Sea. Combined pteropods contributed food with a mucous web. The ingestion rates of L. retroversa australis are in the upper range for sub-Antarctic mesozooplankton (31.2-4196.9 ng pig ind -1 d -1), while those of L. helicina antarctica and C. pyramidata are in the upper range for all Southern Ocean zooplankton, in the latter species reaching 27,757 ng pig ind -1 d -1 and >40% of community grazing impact. Further research is required to quantify diet selectivity, the effect of phytoplankton composition on growth and reproductive success, and the role of carnivory in thecosomes. Life histories are a

  20. Dusty Skies over Southern California

    Science.gov (United States)

    2002-01-01

    Southern California's 'Santa Anas' are dry, north-easterly winds having speeds in excess of 25 knots (46 kilometers/hour). Santa Ana conditions are commonly associated with gusts of more than twice this level. These offshore winds usually occur in late fall and winter when a high pressure system forms in the Great Basin between the Sierra Nevadas and the Rocky Mountains. The air warms as it flows downslope from the high plateau, and its speed increases dramatically when forced through narrow canyons and mountain passes. Due to Southern California's uneven terrain, the strength of the winds varies greatly from place to place, and the Santa Anas can be sufficiently strong to pick up surface dust.This view from the Multi-angle Imaging SpectroRadiometer shows the pattern of airborne dust stirred up by Santa Ana winds on February 9, 2002. The image is from MISR's 70-degree forward-viewing camera, and airborne particulates are especially visible due to the camera's oblique viewing angle. Southeast of the Los Angeles Basin, a swirl of dust, probably blown through the Banning Pass, curves toward the ocean near Dana Point. The largest dust cloud occurs near Ensenada, in Baja California, Mexico. Also visible in this image is a blue-gray smoke plume from a small fire located near the southern flank of Palomar Mountain in Southern California.This image was acquired during Terra orbit 11423, and represents an area of about 410 kilometers x 511 kilometers.MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

  4. Youth Unemployment in Southern Europe

    OpenAIRE

    João Leão; Guida Nogueira

    2013-01-01

    The youth unemployment rate in Europe increased to very high levels after the great recession of 2008, reaching 23% in European Union and 45% in southern European countries. We examine the causes of the high youth unemployment rate which is consistently bigger than the overall unemployment rate. The empirical evidence shows that the youth unemployment rate depends crucially of the level of the overall unemployment rate and on the variation of the unemployment rate.

  5. Agro-fuels: southern impacts

    International Nuclear Information System (INIS)

    Duterme, B.

    2011-01-01

    At a time of controversies about global warming, agro-fuels production is often presented as a future solution for automotive fuels and as a new way of development for southern countries. However, in Asia, South America and Africa, it very often takes the form of huge mono-culture areas of sugar cane, palm oil and soy bean in the hands of multinational companies of the agriculture and food industry. The consequences of these land, social and environmental impacts in Southern countries is an increase of disequilibria and a threat for the diet of local populations by changing the appropriation of lands. Deforestation, private monopolization of lands, concentration of profits, soils and water pollution, biodiversity impoverishment, exploitation of vulnerable manpower, populations migration, violation of human rights are today the consequences of mass production of agro-fuels in Southern countries. To what conditions a fair re-appropriation and a sustainable development of agro-fuels production and consumption is foreseeable? The solutions require a re-shaping of economical and agricultural politics. The book gathers testimonies and analyses from specialists who have evaluated locally the consequences of these energy choices. (J.S.)

  6. Southern Appalachian Regional Seismic Network

    Energy Technology Data Exchange (ETDEWEB)

    Chiu, S.C.C.; Johnston, A.C.; Chiu, J.M. [Memphis State Univ., TN (United States). Center for Earthquake Research and Information

    1994-08-01

    The seismic activity in the southern Appalachian area was monitored by the Southern Appalachian Regional Seismic Network (SARSN) since late 1979 by the Center for Earthquake Research and Information (CERI) at Memphis State University. This network provides good spatial coverage for earthquake locations especially in east Tennessee. The level of activity concentrates more heavily in the Valley and Ridge province of eastern Tennessee, as opposed to the Blue Ridge or Inner Piedmont. The large majority of these events lie between New York - Alabama lineament and the Clingman/Ocoee lineament, magnetic anomalies produced by deep-seated basement structures. Therefore SARSN, even with its wide station spacing, has been able to define the essential first-order seismological characteristics of the Southern Appalachian seismic zone. The focal depths of the southeastern U.S. earthquakes concentrate between 8 and 16 km, occurring principally beneath the Appalachian overthrust. In cross-sectional views, the average seismicity is shallower to the east beneath the Blue Ridge and Piedmont provinces and deeper to the west beneath the Valley and Ridge and the North American craton. Results of recent focal mechanism studies by using the CERI digital earthquake catalog between October, 1986 and December, 1991, indicate that the basement of the Valley and Ridge province is under a horizontal, NE-SW compressive stress. Right-lateral strike-slip faulting on nearly north-south fault planes is preferred because it agrees with the trend of the regional magnetic anomaly pattern.

    The seismic activity in the southern Appalachian area was monitored by the Southern Appalachian Regional Seismic Network (SARSN) since late 1979 by the Center for Earthquake Research and Information (CERI) at Memphis State University. This network provides good spatial coverage for earthquake locations especially in east Tennessee. The level of activity concentrates more heavily in the Valley and Ridge province of eastern Tennessee, as opposed to the Blue Ridge or Inner Piedmont. The large majority of these events lie between New York - Alabama lineament and the Clingman/Ocoee lineament, magnetic anomalies produced by deep-seated basement structures. Therefore SARSN, even with its wide station spacing, has been able to define the essential first-order seismological characteristics of the Southern Appalachian seismic zone. The focal depths of the southeastern U.S. earthquakes concentrate between 8 and 16 km, occurring principally beneath the Appalachian overthrust. In cross-sectional views, the average seismicity is shallower to the east beneath the Blue Ridge and Piedmont provinces and deeper to the west beneath the Valley and Ridge and the North American craton. Results of recent focal mechanism studies by using the CERI digital earthquake catalog between October, 1986 and December, 1991, indicate that the basement of the Valley and Ridge province is under a horizontal, NE-SW compressive stress.

    2011-01-01

    During the southern African dry season, regional haze from mixed industrial pollution, biomass burning aerosol and gases from domestic and grassland fires, and biogenic sources from plants and soils is worsened by a semi-permanent atmosphere gyre over the subcontinent. These factors were a driver of several major international field campaigns in the 1990s and early 2000s, and attracted many scientists to the region. Some researchers were interested in understanding fundamental processes governing chemistry of the atmosphere and interaction with climate change. Others found favorable conditions for evaluating satellite-derived measurements of atmospheric properties and a changing land surface. With that background in mind a workshop on atmospheric chemistry was held in South Africa. Sponsored by the International Commission for Atmospheric Chemistry and Global Pollution (ICACGP; http://www.icacgp.org/), the workshop received generous support from the South African power utility, Eskom, and the Climatology Research Group of the University of the Witwatersrand, Johannesburg, South Africa. The purpose of the workshop was to review some earlier findings as well as more recent findings on southern African climate vulnerability, chemical changes due to urbanization, land-use modification, and how these factors interact. Originally proposed by John Burrows, president of ICACGP, the workshop was the first ICACGP regional workshop to study the interaction of air pollution with global chemical and climate change. Organized locally by the University of the Witwatersrand, the workshop attracted more than 60 delegates from South Africa, Mozambique, Botswana, Zimbabwe, France, Germany, Canada, and the United States. More than 30 presentations were given, exploring both retrospective and prospective aspects of the science. In several talks, attention was focused on southern African chemistry, atmospheric pollution monitoring, and climate processes as they were studied in the field

  9. Thunderstorms caused by southern cyclones in Estonia

    2014-05-01

    Full Text Available The relationships between the frequency and duration of thunderstorms, lightning and southern cyclones over Estonia are presented for the period 1950–2010. A total of 545 southern cyclones and 2106 thunderstorm days were detected, whereas 11.3% of the observed thunder days were associated with southern cyclones. At the same time, 29.2% of all southern cyclones were accompanied by thunderstorms. In the thunder season, however, this percentage was much higher, reaching up to 80% in summer months. The number of thunder days was largest when the centres of southern cyclones passed a measuring station at a distance less than 500 km. The number of cloud-to-ground lightning strikes related to southern cyclones was larger than that of any other thunder events. The results of our study demonstrate that the intensity of thunderstorms related to southern cyclones is higher than that of other thunderstorms. Correlation analysis revealed statistically significant relationships between the frequency of thunder days related to southern cyclones and the frequency of southern cyclones, also between the frequency of thunder days related to southern cyclones and days of other thunder events.

  10. Geothermal resources of southern Idaho

    Mabey, Don R.

    1983-01-01

    The geothermal resource of southern Idaho as assessed by the U.S. Geological Survey in 1978 is large. Most of the known hydrothermal systems in southern Idaho have calculated reservoir temperatures of less than 150?C. Water from many of these systems is valuable for direct heat applications, but is lower than the temperature of interest for commercial generation of electricity at the present time. Most of the known and inferred geothermal resources of southern Idaho underlie the Snake River Plain. However, major uncertainties exist concerning the geology and temperatures beneath the plain. By far the largest hydrothermal system in Idaho is in the Bruneau-Grand View area of the western Snake River Plain with a calculated reservoir temperature of 107?C and an energy of 4.5? 10 20 joules. No evidence of higher temperature water associated with this system has been found. Although the geology of the eastern Snake River Plain suggests that a large thermal anomaly may underlie this area of the plain, direct evidence of high temperatures has not been found. Large volumes of water at temperatures between 90? and 150?C probably exist along the margins of the Snake River Plain and in local areas north and south of the plain. Areas that appear particularly promising for the occurrence of large high-temperature hydrothermal systems are: the area north of the Snake River Plain and west of the Idaho batholith, the Island Park area, segments of the margins of the eastern Snake River Plain, and the Blackfoot lava field.

    The National Geophysical Data Center (NGDC), an office of the National Oceanic and Atmospheric Administration (NOAA), in conjunction with the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado at Boulder, has developed a 24 arc-second integrated bathymetric-topographic digital elevation model of Southern Alaska. This Coastal Relief Model (CRM) was generated from diverse digital datasets that were obtained from NGDC, the United States Geological Survey, and other U.S. and international agencies. The CRM spans 170° to 230° E and 48.5° to 66.5° N, including the Gulf of Alaska, Bering Sea, Aleutian Islands, and Alaska’s largest communities: Anchorage, Fairbanks, and Juneau. The CRM provides a framework for enabling scientists to refine tsunami propagation and ocean circulation modeling through increased resolution of geomorphologic features. It may also be useful for benthic habitat research, weather forecasting, and environmental stewardship. Shaded-relief image of the Southern Alaska Coastal Relief Model.

    2016-02-01

    The Southern Ocean is fundamental to the operation of the Earth system, as it plays a central role in global climate and planetary-scale biogeochemical cycles. The Southern Ocean is changing rapidly, and the critical need to observe and understand the Southern Ocean is well established; however, the harsh conditions and remote location have led to it being the most under-sampled region of the world. Sustained observations are required to detect, interpret, and respond to the physical, chemical, and biological changes that are, and will continue to be measured. The Southern Ocean Observing System (SOOS) is an international initiative with the mission to integrate the global assets and efforts of the international community to enhance data collection, provide access to datasets, and guide the development of strategic-sustained-multidisciplinary science in the Southern Ocean. This presentation will provide an update on SOOS implementation activities, key products and tools, and data management efforts.

  4. The southern cone petroleum market

    International Nuclear Information System (INIS)

    Pisani, W.

    1992-01-01

    The Argentine oil sector has been moving strongly toward complete deregulation since 1989. Price controls on byproducts has been lifted, old petroleum contracts became into concessions, and the state oil company, YPF, is under process of privatization. In this context, the international companies scouting for opportunities can find an important menu of potential investments But here remain some problems connected with this deregulation, too. The lack of a reference crude and product market price is one of them. This paper focuses how to overcome this trouble with the establishment of an institutional market for crude and products, not only for Argentina but also for the entire Southern Cone Region (Argentina, Bolivia, Brazil, Chile, Paraguay and Uruguay), inquiring into the benefits of its creation

    Crinum macowanii is a deciduous bulbous plant which grows in east, central and southern Africa. Crinum macowanii has been used as herbal medicine by the indigenous people of east and southern Africa has for several centuries. The bulb, leaves and roots of C. macowanii are reported to possess diverse medicinal properties and used to treat or manage various human and animal diseases and ailments throughout its distributional range. Crinum macowanii is used traditionally as a remedy for boils, diarrhoea, fever, inflammation, respiratory system problems, skin rashes, tuberculosis, wounds and urinary tract problems. The present review aims to summarize comprehensively the research that has been done on the ethnomedicinal uses, botany, phytochemistry and pharmacology of C. macowanii in different locations throughout its geographical range in east, central and southern African region so as to highlight research gaps and provide a foundation for further investigations on the plant species. A review of the literature was undertaken and an in-depth analysis of previous research on ethnobotany, therapeutic value, phytochemistry and pharmacology of C. macowanii throughout its distributional range in east, central and southern Africa. Literature sources included papers published in international journals, reports from international, regional and national organizations, conference papers, books, theses, websites and other grey literature. Electronic search engines such as Google, Google scholar, publishing sites such as Elsevier, scienceDirect, BMC, PubMed and other scientific database sites such as ChemSpider, PubChem were used as well as searching the library collections of the National Herbarium and Botanic Gardens (SRGH), Harare, Zimbabwe and the University of Fort Hare, South Africa. A total of 32 ethnomedicinal uses of C. macowanii are documented in literature, which can be grouped into seven major ethnomedicinal general purpose usages, namely "fever", "wounds, sores and

    2013-03-01

    This study evaluates the business case for additional bulk electric energy storage in the Southern Company service territory for the year 2020. The model was used to examine how system operations are likely to change as additional storage is added. The storage resources were allowed to provide energy time shift, regulation reserve, and spinning reserve services. Several storage facilities, including pumped hydroelectric systems, flywheels, and bulk-scale batteries, were considered. These scenarios were tested against a range of sensitivities: three different natural gas price assumptions, a 15% decrease in coal-fired generation capacity, and a high renewable penetration (10% of total generation from wind energy). Only in the elevated natural gas price sensitivities did some of the additional bulk-scale storage projects appear justifiable on the basis of projected production cost savings. Enabling existing peak shaving hydroelectric plants to provide regulation and spinning reserve, however, is likely to provide savings that justify the project cost even at anticipated natural gas price levels. Transmission and distribution applications of storage were not examined in this study. Allowing new storage facilities to serve both bulk grid and transmission/distribution-level needs may provide for increased benefit streams, and thus make a stronger business case for additional storage.

  12. Slowly Spinning Southern M Dwarfs

    2018-01-01

    M dwarf stars are the most common type of star in the galaxy, but their ages are challenging to determine due to their trillion-year lifetimes on the main sequence. Consequently, the evolution of rotation and magnetism at field ages is difficult to investigate observationally. M dwarfs in the Solar Neighborhood provide a unique opportunity to make progress in this area due to the availability of parallaxes and the accessibility of spectroscopy. We have used new rotation period measurements and our compilation of H-alpha emission for nearby M dwarfs to explore two questions: 1) What is the longest rotation period an M dwarf can have? And 2) Do M dwarfs undergo an era of rapid angular momentum evolution? Here, we focus on the view from the Southern hemisphere, presenting approximately 200 new rotation periods for fully convective M dwarfs. Amongst the highest-quality datasets, we identify rotation periods in three-quarters of all stars; of these, half have rotation periods longer than 70 days. The longest rotation period we detect is 148 days, which is for a 0.15 solar-mass star. The lack of M dwarfs with intermediate rotation periods that we previously identified persists, supporting our hypothesis that M dwarfs rapidly spin down from 10-day to 100-day periods.ERN is supported by the National Science Foundation Astronomy & Astrophysics Postdoctoral Fellowship.

    2009-01-01

    Efforts to form this Alliance began in 2008 to showcase the impact testing capabilities within the southern United States. Impact testing customers can utilize SITA partner capabilities to provide supporting data during all program phases-materials/component/ flight hardware design, development, and qualification. This approach would allow programs to reduce risk by providing low cost testing during early development to flush out possible problems before moving on to larger scale1 higher cost testing. Various SITA partners would participate in impact testing depending on program phase-materials characterization, component/subsystem characterization, full-scale system testing for qualification. SITA partners would collaborate with the customer to develop an integrated test approach during early program phases. Modeling and analysis validation can start with small-scale testing to ensure a level of confidence for the next step large or full-scale conclusive test shots. Impact Testing Facility (ITF) was established and began its research in spacecraft debris shielding in the early 1960's and played a malor role in the International Space Station debris shield development. As a result of return to flight testing after the loss of STS-107 (Columbia) MSFC ITF realized the need to expand their capabilities beyond meteoroid and space debris impact testing. MSFC partnered with the Department of Defense and academic institutions as collaborative efforts to gain and share knowledge that would benefit the Space Agency as well as the DoD. MSFC ITF current capabilities include: Hypervelocity impact testing, ballistic impact testing, and environmental impact testing.

    2018-02-01

    The Southern Ocean is the largest sink of anthropogenic carbon in the present-day climate. Here, Southern Ocean pCO2 and its dependence on wind forcing are investigated using an equilibrium mixed layer carbon budget. This budget is used to derive an expression for Southern Ocean pCO2 sensitivity to wind stress. Southern Ocean pCO2 is found to vary as the square root of area-mean wind stress, arising from the dominance of vertical mixing over other processes such as lateral Ekman transport. The expression for pCO2 is validated using idealised coarse-resolution ocean numerical experiments. Additionally, we show that increased (decreased) stratification through surface warming reduces (increases) the sensitivity of the Southern Ocean pCO2 to wind stress. The scaling is then used to estimate the wind-stress induced changes of atmospheric pCO_2 in CMIP5 models using only a handful of parameters. The scaling is further used to model the anthropogenic carbon sink, showing a long-term reversal of the Southern Ocean sink for large wind stress strength.

  15. Emigration dynamics in southern Africa.

    Milazi, D

    1995-01-01

    This review of the dynamics of international migration in Southern Africa focuses on four aspects of labor migration: 1) while migrant workers suffer from discrimination and lack of protection, there are few alternatives for them; 2) the regulations imposed by the Chamber of Mines in South Africa favor the mining industry at the expense of the workers; 3) worker supplier states have few options for negotiating a commercialized migration policy to achieve economic benefits; and 4) foreign mine workers must unionize in order to escape perpetual subordination. The review opens with a consideration of how migrant mine workers from Botswana, Lesotho, and Swaziland have provided a source of cheap labor which has enhanced the economic prosperity of South Africa. The role of the Chamber of Mines in regulating the supply of labor and employment policy for its members is described. Attention is then turned to Lesotho where land pressure has exacerbated poverty levels. Large-scale migration has led the citizens of Lesotho to consider it a place to live or retire to, not a place to work. Labor migration from Lesotho is organized, is supported by the government, is recurrent, and remains a viable alternative despite faltering demand. The discussion of Lesotho includes a consideration of its political, economic, and demographic situation as well as of ecological factors. Briefer analyses are then provided for Botswana, Swaziland, and Mozambique. The receiving country, South Africa, is shown to be suffering a decline in economic growth which is marked by widespread unemployment. More than 250,000 Whites are prospective emigrants from South Africa. After considering the issues surrounding refugees, regional concerns created by changing economic and political scenarios, and labor strategies which could be adopted by supplier states, the report reiterates a series of recommendations which arose from two major conferences on the problem of unemployment. It is concluded that the

  16. Detection of Borrelia burgdorferi and Borrelia lonestari in birds in Tennessee.

    Lyme disease in the United States is caused by the bacterial spirochete Borrelia burgdorferi s.s. (Johnson, Schmid, Hyde, Steigerwalt, and Brenner), which is transmitted by tick vectors Ixodes scapularis (Say) and I. pacificus (Cooley and Kohls). Borrelia lonestari, transmitted by the tick Amblyomma americanum L., may be associated with a related syndrome, southern tick-associated rash illness (STARI). Borrelia lonestari sequences, reported primarily in the southeastern states, have also been detected in ticks in northern states. It has been suggested that migratory birds may have a role in the spread of Lyme disease spirochetes. This study evaluated both migratory waterfowl and nonmigratory wild turkeys (Meleagris gallopavo silvestris, Eastern wild turkey) for B. burgdorferi and B. lonestari DNA sequences. A total of 389 avian blood samples (163 migratory birds representing six species, 125 wild turkeys harvested in habitats shared with migratory birds, 101 wild turkeys residing more distant from migratory flyways) were extracted, amplified, and probed to determine Borrelia presence and species identity. Ninety-one samples were positive for Borrelia spp. Among migratory birds and turkeys collected near migration routes, B. burgdorferi predominated. Among turkeys residing further away from flyways, detection of B. lonestari was more common. All A. americanum ticks collected from these areas were negative for Borrelia DNA; no I. scapularis were found. To our knowledge, this represents the first documentation of B. lonestari among any birds.

    Southern tick-associated rash illness (STARI), also known as Masters disease, affects people predominantly in the Southeast and South Central United States. These patients exhibit skin lesions that resemble erythema migrans (EM), the characteristic skin lesion in early Lyme disease. The etiology of STARI remains unknown, and no serologic test is available to aid in its diagnosis. The C6 Lyme enzyme-linked immunosorbent assay was used to evaluate coded serum specimens from patients with STARI at two laboratory sites. The specimens tested at one site consisted of acute- and convalescent-phase samples that were obtained from nine STARI patients from Missouri and from one patient with documented Borrelia lonestari infection who acquired this infection in either North Carolina or Maryland. All of these samples were C6 negative. Seventy acute- or convalescent-phase specimens from 63 STARI patients from Missouri were C6 tested at the second site. All but one of these STARI specimens were also negative. In contrast, of nine acute- and nine convalescent-phase serum specimens obtained from culture-confirmed Lyme disease patients with EM from New York state, seven were C6 positive at the acute stage, and eight were positive at convalescence. The C6 test is negative in patients with STARI, providing further evidence that B. burgdorferi is not the etiologic agent of this disease.

    Southern and eastern African populations that speak non-Bantu languages with click consonants are known to harbour some of the most ancient genetic lineages in humans, but their relationships are poorly understood. Here, we report data from 23 populations analysed at over half a million single-nucleotide polymorphisms, using a genome-wide array designed for studying human history. The southern African Khoisan fall into two genetic groups, loosely corresponding to the northwestern and southeastern Kalahari, which we show separated within the last 30,000 years. We find that all individuals derive at least a few percent of their genomes from admixture with non-Khoisan populations that began ∼1,200 years ago. In addition, the East African Hadza and Sandawe derive a fraction of their ancestry from admixture with a population related to the Khoisan, supporting the hypothesis of an ancient link between southern and eastern Africa.

    Full Text Available The objective of this paper is to estimate the indirect tax burden on food for ten income classes, based on income and household total expenditure in southern Brazil. Thus it can be seen as indirect taxes on foods affect the monetary income and consumption pattern of households. To reach the objectives proposed, will be used the Pintos-Payeras (2008 model. The database iscomposed by microdata from the Household Budgeting Survey (POF 2008-2009 and the tax regulations of the country and the southern states of Brazil. The results show that indirect taxes on food in Southern Brazil is regressive when based on income and expenditure of household , ie , the poorest people pay proportionately more taxes and have their consumption pattern highest taxed ICMS (Brazilian value added tax is the tax that contributes most to the regressivity.

    Full Text Available Abstract Southern Alberta Information Resources (SAIR is a collaborative bibliography of published resources significant to southern Alberta. Objectives and progress with evolving methodology, technology, issues and challenges are explored within the context of the library field. We investigate a collaborative digital library that allows librarians and non-librarians alike to share information on specific topics through MARC records. An outcome of a collaborative digital library is how to create and sustain interest within the library community. Southern Alberta region was selected based on the authors’ familiarity with the region. Some issues and questions remain to be resolved. Digital formats present a number of challenges in terms of selection and presentation. Legal issues relating to technology such as linking and location information have emerged. Basic technical issues remain, such as, how best to update links.

  1. Reducing Tick-Borne Disease in Alabama: Linking Health Risk Perception with Spatial Analysis Using the NASA Earth Observing System

    Lyme disease (LD) accounts for most vector-borne disease reports in the U.S., and although its existence in Alabama remains controversial, other tick-borne illnesses (TBI) such as Southern Tick-Associated Rash Illness (STARI) pose a health concern in the state. Phase One of the Marshall Space Flight Center-UAB DEVELOP study of TBI identified the presence of the chain of infection for LD (Ixodes scapularis ticks carrying Borrelia burgdorferi bacteria) and STARI (Amblyomma americanum ticks and an as-yet-unconfirmed agent) in Alabama. Both LD and STARI are associated with the development of erythema migrans rashes around an infected tick bite, and while treatable with oral antibiotics, a review of educational resources available to state residents revealed low levels of prevention information. To improve prevention, recognition, and treatment of TBI in Alabama, Phase Two builds a health communication campaign based on vector habitat mapping and risk perception assessment. NASA Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite imagery identified likely tick habitats using remotely sensed measurements of vegetation vigor (Normalized Difference Vegetation Index) and soil moisture. Likely tick habitats, identified as those containing both high vegetation density and soil moisture, included Oak Mountain State Park, Bankhead National Forest, and Talladega National Forest. To target a high-risk group -- outdoor recreation program participants at Alabama universities -- the study developed a behavior survey instrument based on existing studies of LD risk factors and theoretical constructs from the Social Ecological Model and Health Belief Model. The survey instrument was amended to include geographic variables in the assessment of TBI knowledge, attitudes, and prevention behaviors, and the vector habitat model will be expanded to incorporate additional environmental variables and in situ data. Remotely sensed environmental data combined with

  2. The Southern Kalahari: a potential new dust source in the Southern Hemisphere?

    Most sources of atmospheric dust on Earth are located in the Northern Hemisphere. The lower dust emissions in the Southern Hemisphere in part limit the supply of micronutrients (primarily soluble iron) to the Southern Ocean, thereby constraining its productivity. Climate and land use change can alter the current distribution of dust source regions on Earth. Can new dust sources be activated in the Southern Hemisphere? Here we show that vegetation loss and dune remobilization in the Southern Kalahari can promote dust emissions comparable to those observed from major contemporary dust sources in the Southern African region. Dust generation experiments support the hypothesis that, in the Southern Kalahari, aeolian deposits that are currently mostly stabilized by savanna vegetation are capable of emitting substantial amounts of dust from interdune areas. We show that dust from these areas is relatively rich in soluble iron, an important micronutrient for ocean productivity. Trajectory analyses show that dust from the Kalahari commonly reaches the Southern Ocean and could therefore enhance its productivity. (letter)

    This study was conducted in October 1998 and November 1999 in the Emas National Park (131,868 ha), a savanna-type cerrado region situated in the far south of Goias State, Brazil, near the geographic center of South America (15 degrees -23 degrees S; 45 degrees -55 degrees W). Animals were captured with the aid of nets and anesthetized (15 mg/kg ketamine + 1 mg/kg xylasine) in order to collect ticks for identification and to establish laboratory colonies. They included giant anteaters (Myrmecophaga tridactyla) (n = 4) and yellow armadillos (Euphractus sexcinctus) (n = 6). Free-living ticks (larvae, nymphs, and adults) were collected from the field by using a 1 x 2-m flannel cloth. Free-living ticks were identified as Amblyomma sp., A. cajennense, and A. triste. Adult ticks collected from anteaters were identified as Amblyomma cajennense and A. nodosum and from armadillos as A. pseudoconcolor and A. nodosum. The relevance of these host-tick relationships to possible mechanisms underlying emergence of tick-borne pathogens of importance to public health is discussed.

  7. Faulkner's Southern belle - myth or reality?

    Directory of Open Access Journals (Sweden)

    Nataša Intihar Klančar

    2011-12-01

    Full Text Available The article deals with heroines of William Faulkner's novels Light in August, Absalom, Absalom!, The Sound and the Fury, The Unvanquished, The Town and his short story "A Rose for Emily". The Southern belle features as a recurring character in Faulkner's fiction, her fragility, modesty, weakness yet strength, beauty, sincerity, generous nature, status and her fall from innocence comprise her central characteristics. Confronted with various expectations of Southern society and with the hardships of war, the belle is faced with many obstacles and challenges. Faulkner's heroines face a wide array of problems that prevent them from being and/or remaining a Southern belle. Let us name a few: Lena's inappropriate social status, Joanna's wrong roots, Mrs. Hightower's inability to fulfill her duties as the minister's wife, Ellen's miserable marriage, Judith's sad love life, Rosa's feelings of inferiority and humiliation, Mrs. Compson's failure as a mother, Caddy's weak rebellion against male convention, Drusilla's male characteristics, Linda's unrequited love and Emily's dark secret, to name a few. Through these characters and their destinies Faulkner shows a decaying South whose position has changed considerably over the years. Can the Southern belle save it? Can she save herself?

    Full Text Available A subset of invasive alien plant species in southern Africa was analysed in terms of their history of introduction, rate of spread, countries/region of origin, taxonomy, growth forms, cultivated uses, weed status and current distribution in southern Africa, and comparisons made of those originating from south of the tropic of Capricorn, north of the tropic of Cancer and from the tropics. The subset of 233 species, belonging to 58 families, includes all important declared species and some potentially important species. Almost as many species originate from temperate regions (112 as from the tropics (121. Most southern temperate species came from Australia (28/36, most tropical species from tropical America (92/121 and most northern temperate species from Europe (including the Mediterranean and Asia (58/76. Transformers account for 33% of  all species. More transformers are of tropical origin (36 than of northern temperate (24 and southern temperate origin (18. However. 50% of southern temperate species are transformers, compared to 32% of northern temperate and 29% of tropical species. Southern temperate transformer species are mainly woody trees and shrubs that were established on a grand scale as silvicultural crops, barriers (hedges, windbreaks and screens and cover/binders. Most aquatics, herbs, climbers and succulent shrubs an. trom the tropics. Ornamentals are the single largest category of plants from all three regions, the tropics having contributed twice as many species as temperate regions.

  7. Support for the Confederate Battle Flag in the Southern United States: Racism or Southern Pride?

    Directory of Open Access Journals (Sweden)

    Joshua D. Wright

    2017-05-01

    Full Text Available Supporters of the Confederate battle flag often argue that their support is driven by pride in the South, not negative racial attitudes. Opponents of the Confederate battle flag often argue that the flag represents racism, and that support for the flag is an expression of racism and an attempt to maintain oppression of Blacks in the Southern United States. We evaluate these two competing views in explaining attitudes toward the Confederate battle flag in the Southern United States through a survey of 526 Southerners. In the aggregate, our latent variable model suggests that White support for the flag is driven by Southern pride, political conservatism, and blatant negative racial attitudes toward Blacks. Using cluster-analysis we were able to distinguish four distinct sub-groups of White Southerners: Cosmopolitans, New Southerners, Traditionalists, and Supremacists. The greatest support for the Confederate battle flag is seen among Traditionalists and Supremacists; however, Traditionalists do not display blatant negative racial attitudes toward Blacks, while Supremacists do. Traditionalists make up the majority of Confederate battle flag supporters in our sample, weakening the claim that supporters of the flag are generally being driven by negative racial attitudes toward Blacks.

    2009-04-01

    Full Text Available Abstract Purpura fulminans (PF is an ominous cutaneous condition usually associated with meningococcemia. PF in the newborn is rarely reported. We report the case of a female preterm infant with extensive PF due to group B streptococcus (GBS septicemia. She developed multi-organ system failure despite neonatal intensive care support and succumbed 9 days later. GBS, sensitive to penicillin, was isolated from the blood cultures of the mother and the infant. Invasive early GBS infection is common in the newborn and is empirically treated with prompt institution of intravenous antibiotics. PF associated with GBS is a rare cutaneous sign that must not be missed. Mortality remains high despite aggressive treatment and ICU support.

    2011-01-01

    Full Text Available Introduction. The authors are presenting a case of Thrombotic Thrombocytopenic Purpura (TTP that presented with complaints of altered mental status and found to have petechiae. Case Presentation. An 81-year-old female patient presented to the Emergency Department (ED of a tertiary care hospital with chief complains of dizziness, slurred speech, and weakness. She was found to have lower extremity petechiae on physical examination. On blood exam, she had thrombocytopenia, and her peripheral blood smear showed schistocytes. Her renal function was also impaired. The CT scan of head was without any abnormality. She was finally diagnosed as having TTP and transferred to ICU but ultimately passed away. Conclusion. TTP is a rare syndrome with preventable mortality if diagnosed early and managed appropriately with plasmapheresis. The Emergency Department physicians should be aware of the presenting symptoms and signs of TTP.

  18. Emerging arboviral human diseases in Southern Europe.

    Science.gov (United States)

    Papa, Anna

    2017-08-01

    Southern Europe is characterized by unique landscape and climate which attract tourists, but also arthropod vectors, some of them carrying pathogens. Among several arboviral diseases that emerged in the region during the last decade, West Nile fever accounted for high number of human cases and fatalities, while Crimean-Congo hemorrhagic fever expanded its geographic distribution, and is considered as a real threat for Europe. Viruses evolve rapidly and acquire mutations making themselves stronger and naive populations more vulnerable. In an effort to tackle efficiently the emerging arboviral diseases, preparedness and strategic surveillance are needed for the early detection of the pathogen and containment and mitigation of probable outbreaks. In this review, the main human arboviral diseases that emerged in Southern Europe are described. © 2017 Wiley Periodicals, Inc.

    During a dengue epidemic in northern Mexico, enhanced surveillance identified 53 laboratory-positive cases in southern Texas; 26 (49%) patients acquired the infection locally, and 29 (55%) were hospitalized. Of 83 patient specimens that were initially IgM negative according to ELISA performed at a commercial laboratory, 14 (17%) were dengue virus positive by real-time reverse transcription PCR performed at the Centers for Disease Control and Prevention. Dengue virus types 1 and 3 were identified, and molecular phylogenetic analysis demonstrated close identity with viruses that had recently circulated in Mexico and Central America. Of 51 household members of 22 dengue case-patients who participated in household investigations, 6 (12%) had been recently infected with a dengue virus and reported no recent travel, suggesting intrahousehold transmission. One household member reported having a recent illness consistent with dengue. This outbreak reinforces emergence of dengue in southern Texas, particularly when incidence is high in northern Mexico.

  20. Marketing of organic products in southern Poland

    Directory of Open Access Journals (Sweden)

    Kuboń Maciej

    2018-01-01

    Full Text Available The article presents an outline of the issue concerning formulation of a marketing strategy and the possibility of using the knowledge on consumers' preferences for organic development of farms and their products on the example of southern Poland. The paper analyses the distribution process of organic food in the aspect of developing innovative marketing strategies. The studies were performed in 50 organic farms and on the example of 100 respondents from the region of southern Poland. In the opinion of the surveyed representatives of the organic food producers, a competitive advantage of their offer depends the most on the health values, brand, reputation, and taste. Moreover, information on products and the form and place of their sale are significant. The analysis shows that the knowledge is the most eagerly obtained from the Internet. Thus, producers should publish their profiles and pages on social media and business portals.

  7. Contemporary Russia Policy for the Southern Caucasus

    Directory of Open Access Journals (Sweden)

    Karen P. Marabyan

    2014-01-01

    Full Text Available The bilateral relations between Russia on the one hand, and the countries of the Southern Caucasus region on the other hand are examined in the article. The main directions of Russian policy in the Southern Caucasus region are examined there. The article focusses attention to the value of the Southern Caucasus region for Russia and also to the key role of Russia in the Southern Caucasus region. The overview of Russian-Azerbaijani, Russian-Armenian and Russian- Georgian relations is given in the article. Russian relations with unrecognized Nagorno-Karabakh Republic and with partially recognized Abkhazia and South Ossetia are examined in the context of above-mentioned bilateral relations. The Caucasian direction of Russian foreign policy is of great importance in questions of ensuring Russian national security. The Caucasian crisis of2008 showed potential conflictness of the region and safety hazard of Russia. Now other processes proceed already in the region. Armenian intention to join the Customs union, the change of Georgian leadership and signing of the agreement on association with EU by Georgia start new mechanisms of interaction between the region countries on the one hand and Russia on the other hand. The relation format between region republics can be changed. The main purpose of the article is to show Russian role in questions of the South Caucasus regional security. The region has the conflict territories, from which the Nagorno-Karabakh Republic, the Abkhazian Republic and the South Ossetia Republic are distinguished especially. And Russia won't be able to keep aloof in case of escalation of the conflicts around above-mentioned subjects. The vital questions for the region are peace and stability. And Russia plays a key role in these questions.

  8. Parameterized and resolved Southern Ocean eddy compensation

    Science.gov (United States)

    Poulsen, Mads B.; Jochum, Markus; Nuterman, Roman

    2018-04-01

    The ability to parameterize Southern Ocean eddy effects in a forced coarse resolution ocean general circulation model is assessed. The transient model response to a suite of different Southern Ocean wind stress forcing perturbations is presented and compared to identical experiments performed with the same model in 0.1° eddy-resolving resolution. With forcing of present-day wind stress magnitude and a thickness diffusivity formulated in terms of the local stratification, it is shown that the Southern Ocean residual meridional overturning circulation in the two models is different in structure and magnitude. It is found that the difference in the upper overturning cell is primarily explained by an overly strong subsurface flow in the parameterized eddy-induced circulation while the difference in the lower cell is mainly ascribed to the mean-flow overturning. With a zonally constant decrease of the zonal wind stress by 50% we show that the absolute decrease in the overturning circulation is insensitive to model resolution, and that the meridional isopycnal slope is relaxed in both models. The agreement between the models is not reproduced by a 50% wind stress increase, where the high resolution overturning decreases by 20%, but increases by 100% in the coarse resolution model. It is demonstrated that this difference is explained by changes in surface buoyancy forcing due to a reduced Antarctic sea ice cover, which strongly modulate the overturning response and ocean stratification. We conclude that the parameterized eddies are able to mimic the transient response to altered wind stress in the high resolution model, but partly misrepresent the unperturbed Southern Ocean meridional overturning circulation and associated heat transports.

    Only in Southern California did space-age style really come into its own as a unique expression of Cold War scientific culture. The corporate campuses of General Atomic in San Diego and North American Aviation in Los Angeles perfectly expressed the exhilarating spirit of Southern California's aerospace era, scaling up the residential version of California modernism to industrial proportion. Architects William Pereira and A.C. Martin Jr., in collaboration with their scientific counterparts, fashioned military-industrial `dream factories' for industrial physics that embodied the secret side of the space-age zeitgeist, one the public could only glimpse of in photographs, advertisements, and carefully staged open houses. These laboratories served up archetypes of the California dream for a select audience of scientists, engineers, and military officers, live-action commercials for a lifestyle intended to lure the best and brightest to Southern California. Paradoxically, they hid in plain sight, in the midst of aerospace suburbs, an open secret, at once visible and opaque, the public face of an otherwise invisible empire. Now, at the end of the aerospace era, these places have become an endangered species, difficult to repurpose, on valuable if sometimes highly polluted land. Yet they offer an important reminder of a more confident time when many physicists set their sights on the stars.

  10. Towards Marine Spatial Planning in Southern Taiwan

    Full Text Available Due to population growth, rapid economic development and inadequate marine control, the use of ocean and coastal regions in Taiwan has become more frequent and intense in recent years. However, the lack of comprehensive marine and coastal planning in this island nation has led to many conflicts over space and resources and limited its ability to prepare for and respond to environmental hazards, thus threatening national security as well as the safety and property of its citizens. This study proposes a marine zoning scheme for southern Taiwan. The results show that many important habitats in the southern sea areas have not been properly protected due to the extremely small size of the marine protected area. Furthermore, the majority of the conflicts derive from the exclusive fishing right vs. other uses such as marine conservation. Therefore, it is crucial to establish the marine spatial planning (MSP for the Southern Taiwan to deal with the conflicts of use seas and uncertainties associated with complex, heterogeneous, and dynamic marine system.

  11. Propagation characteristics of thunderstorms in southern Germany

    Energy Technology Data Exchange (ETDEWEB)

    Hagen, M.; Bartenschlager, B.; Finke, U.

    1998-05-01

    The propagation of thunderstorms in southern Germany was investigated. The thunderstorms were observed by a lightning position system during the summer months of the years 1992 to 1996. On average every second day thunderstorms were observed anywhere in southern Germany. In general thunderstorms approach from westerly and south-westerly directions. The average speed is 13 m/s. No significant relation between the occurrence of thunderstorms and the large scale synoptic pattern described by the Grosswetterlagen (large scale weather pattern) was found. Thunderstorms were observed during almost all Grosswetterlagen. The reduction to 8 weather pattern based on the low-level flow in southern Germany showed that thunderstorms are likely when the flow has westerly directions (43%) or easterly directions (20%). Three distinct groups of different lightning patterns could be identified; stationary, moving thunderstorms and thunderstorm lines. The convective available potential energy (CAPE) and the wind shear were retrieved from the radio soundings from Muenchen and Stuttgart. On average CAPE was 583 J/kg for stationary, 701 J/kg for moving thunderstorms, and 876 J/kg for thunderstorm lines. The average bulk Richardson numbers are 152, 80 and 52 for stationary, moving thunderstorms and thunderstorm lines, respectively. The steering level was found to be at about 3 and 6 km m.s.l. However, it should be noted, that in most cases the soundings do not completely describe the local environment of thunderstorms, since radio soundings are only available twice a day. (orig.)

  12. The Economic Impact of Southern Sudan Secession

    2013-07-01

    Full Text Available This paper aims at examining the economic impact of Southern Sudan secession on the economy of both the North and the South, especially its impact on certain economic indicators which include: the exchange rate; government revenue; external debt; and balance of payment; and GDP and per capita income. In addition, the proposed policies to mitigate the negative impact which may take place as a result will be assessed critically.     The results indicate that the economy of the North has been badly affected by the Southern Sudan secession. Hence, the value of the Sudanese Pound against the dollar has deteriorated drastically, while the balance of payment deficit has even widened, and at the same time inflation rates rise steadily to around 28%. In contrast, per capita income has increased, but this was due mainly to the reduction in number of population that took place as a result of Southern Sudan secession. Alternatively, public debt still remains high at 38 billion dollar, with the two parties yet to reach to an agreement over debt apportionment issue.

  13. Ambient Seismic Noise Tomography of Southern Norway

    Köhler, Andreas; Weidle, Christian; Maupin, Valerie

    2010-05-01

    The noise cross-correlation technique is especially useful in regions like southern Norway since local seismicity is rare and teleseismic records are not able to resolve the upper crust. Within the TopoScandiaDeep project, which aims to investigate the relation between surface topography and lithosphere-asthenosphere structure, we process seismic broadband data from the temporary MAGNUS network in Southern Norway. The receivers were recording 20 months of continuous data between September 2006 and June 2008. Additionally, permanent stations of the National Norwegian Seismic Network, NORSAR and GSN stations in the region are used. After usual preprocessing steps (filtering, prewhitening, temporal normalization), we compute 820 cross-correlation functions from 41 receivers for three month time windows. Evaluation of the azimuthal and temporal variation of signal to noise ratios and f-k analysis of NORSAR array data shows that the dominant propagation direction of seismic noise is south-west to north, corresponding well to the Norwegian coast line. During summer months, the signal to noise ratios decrease and the azimuthal distribution becomes smoother. Time-frequency analysis is applied to measure Rayleigh and Love wave group velocity dispersion curves between each station pair for each three-month correlation stack. The mean and variance of all dispersion curves is computed for each path. After rejection of low-quality data using a signal to noise ratio, minimum wavelength and velocity variance criterion, we obtain a large number of reliable velocity estimates (about 600) for periods between 2 and 15 seconds, which we invert for group velocity maps at respective periods. At all inverted periods, we find positive and negative velocity anomalies for Rayleigh and Love waves that correlate very well with local surface geology. While higher velocities (+5%) can be associated with the Caledonian nappes in the central part of southern Norway, the Oslo Graben is reflected

    A wide range of sea surface temperature (SST) expressions have been observed during the El Niño–Southern Oscillation events of 1950–2010, which have occurred simultaneously with different global atmospheric circulations. This study examines the atmospheric circulation and precipitation during December–March 1950–2010 over the African Continent south of 15∘S, a region hereafter known as Southern Africa, associated with eight tropical Pacific SST expressions characteristic of El Niño and La Niña events. The self-organizing map method along with a statistical distinguishability test was used to isolate the SST expressions of El Niño and La Niña. The seasonal precipitation forcing over Southern Africa associated with the eight SST expressions was investigated in terms of the horizontal winds, moisture budget and vertical motion. El Niño events, with warm SST across the east and central Pacific Ocean and warmer than average SST over the Indian Ocean, are associated with precipitation reductions over Southern Africa. The regional precipitation reductions are forced primarily by large-scale mid-tropospheric subsidence associated with anticyclonic circulation in the upper troposphere. El Niño events with cooler than average SST over the Indian Ocean are associated with precipitation increases over Southern Africa associated with lower tropospheric cyclonic circulation and mid-tropospheric ascent. La Niña events, with cool SST anomalies over the central Pacific and warm SST over the west Pacific and Indian Ocean, are associated with precipitation increases over Southern Africa. The regional precipitation increases are forced primarily by lower tropospheric cyclonic circulation, resulting in mid-tropospheric ascent and an increased flux of moisture into the region.

    Edwin M. Southern is a professor emeritus at the University of Oxford. He is perhaps best known for development of the "Southern blot" (Dr. Southern was at the University of Edinburgh when he wrote his landmark paper). The Southern blot provided a scientific breakthrough by allowing scientists to detect a particular DNA sequence without first purifying it from the rest of the genome; the basic method involves the transfer of the DNA to a membrane, followed by detection with a specific probe. Although few people perform Southern blots as originally carried out by Southern, due in part to the more recent technique of the polymerase chain reaction, the basic concept continues to play an important role in molecular biology.

  16. Late-glacial of southern South America

    Science.gov (United States)

    Heusser, C. J.

    Overall trends in late-glacial paleoenvironments of southern South America are interpretable from the pollen stratigraphy of radiocarbon dated sections of mires in Tierra del Fuego (55°S), the Chilotan archipelago (42-43°S), and the Chilean Lake District (39-41°S). In Tierra del Fuego, southern beech ( Nothofagus) and shrub and herb taxa (Gramineae, Empetrum, Acaena, Gunnera, Compositae and Cyperaceae) serve as indicators of the changing climate; in the Chilotan archipelago and in the Chilean Lake District, southern beech and other trees (species of Myrtaceae, Podocarpus, Prumnopitys, Pseudopanax and Weinmannia) suffice as indices of climatic change. Pollen records from each of these regions, although in need of greater dating control, indicate climatic sequences that are broadly similar. The records, however, are not regionally consistent in all aspects and differ in their indicator value with the implication of fossil beetle evidence. Attempts at correlation can be unsatisfactory at times and can stem inter alia from the different ecophysiological responses of both plants and beetles to environmental pressures. These differences, which affect the timing of reproduction and migration, may result in the variable occurrence of different species in the records. The broad implication of the pollen data is that following a glacial readvance culminating at about 15,000-14,500 BP, late-glacial climate was generally warmer during intervals before 13,000 and between 12,000 and 11,000 BP, and was cooler between 13,000 and 12,000 and from 11,000 to 10,000 BP.

  17. Southern Hemisphere Upper Thermospheric Wind Climatology

    Dhadly, M. S.; Emmert, J. T.; Drob, D. P.

    2017-12-01

    This study is focused on the poorly understood large-scale upper thermospheric wind dynamics in the southern polar cap, auroral, and mid latitudes. The gaps in our understanding of the dynamic high-latitude thermosphere are largely due to the sparseness of thermospheric wind measurements. Using data from current observational facilities, it is unfeasible to construct a synoptic picture of the Southern Hemisphere upper thermospheric winds. However, enough data with wide spatial and temporal coverage have accumulated to construct a meaningful statistical analysis of winds as function of season, magnetic latitude, and magnetic local time. We use long-term data from nine ground-based stations located at different southern high latitudes and three space-based instruments. These diverse data sets possess different geometries and different spatial and solar coverage. The major challenge of the effort is to combine these disparate sources of data into a coherent picture while overcoming the sampling limitations and biases among the datasets. Our preliminary analyses show mutual biases present among some of them. We first address the biases among various data sets and then combine them in a coherent way to construct maps of neutral winds for various seasons. We then validate the fitted climatology against the observational data and compare with corresponding fits of 25 years of simulated winds from the National Center for Atmospheric Research Thermosphere-Ionosphere-Electrodynamics General Circulation Model. This study provides critical insight into magnetosphere-ionosphere-thermosphere coupling and sets a necessary benchmark for validating new observations and tuning first-principles models.

  18. Building the Southern California Earthquake Center

    Jordan, T. H.; Henyey, T.; McRaney, J. K.

    2004-12-01

    Kei Aki was the founding director of the Southern California Earthquake Center (SCEC), a multi-institutional collaboration formed in 1991 as a Science and Technology Center (STC) under the National Science Foundation (NSF) and the U. S. Geological Survey (USGS). Aki and his colleagues articulated a system-level vision for the Center: investigations by disciplinary working groups would be woven together into a "Master Model" for Southern California. In this presentation, we will outline how the Master-Model concept has evolved and how SCEC's structure has adapted to meet scientific challenges of system-level earthquake science. In its first decade, SCEC conducted two regional imaging experiments (LARSE I & II); published the "Phase-N" reports on (1) the Landers earthquake, (2) a new earthquake rupture forecast for Southern California, and (3) new models for seismic attenuation and site effects; it developed two prototype "Community Models" (the Crustal Motion Map and Community Velocity Model) and, perhaps most important, sustained a long-term, multi-institutional, interdisciplinary collaboration. The latter fostered pioneering numerical simulations of earthquake ruptures, fault interactions, and wave propagation. These accomplishments provided the impetus for a successful proposal in 2000 to reestablish SCEC as a "stand alone" center under NSF/USGS auspices. SCEC remains consistent with the founders' vision: it continues to advance seismic hazard analysis through a system-level synthesis that is based on community models and an ever expanding array of information technology. SCEC now represents a fully articulated "collaboratory" for earthquake science, and many of its features are extensible to other active-fault systems and other system-level collaborations. We will discuss the implications of the SCEC experience for EarthScope, the USGS's program in seismic hazard analysis, NSF's nascent Cyberinfrastructure Initiative, and other large collaboratory programs.

    Current climate models display a consistent deficit of reflected shortwave radiation over the Southern Ocean which is mainly due to the poor representation of clouds. Recent work has also shown that reanalysis also perform poorly relative to satellite observations in terms of cloud fraction. In particular, satellite observations have shown that low-level clouds (with tops below 3 km) are ubiquitous over the Southern Ocean. But, most satellite instruments, even the current generation of active satellite instruments, have difficulties in sampling low level clouds. As part of the New Zealand Deep South challenge project focussed on improving the representation of clouds in the Southern Ocean, we have begun to deploy autonomous instruments on 'ships of opportunity'. This study discusses measurements from a Väisälä CL51 laser ceilometer and ancillary instruments on the first two research voyages in the Southern Ocean and initial results. The route of the first voyage covers a return trip from Wellington (New Zealand) to Terra Nova Bay (Antarctica) onboard the R/V Tangaroa and occurred in January to mid-February 2015. The second deployment is onboard the Aurora Australis Australian Antarctic Division supply ship and began in October 2015 and is planned to finish at Macquarie Island in March 2016. The sampling provided by the ships route allows the ceilometer measurements of the height of the cloud base in a region where limited data apart from, potentially biased, satellite measurements of low-level cloud exist. Analysis of the boundary layer height derived from the ceilometer is also presented. The climatological structure derived from the ceilometer measurements is first detailed. We then compare these measurements with satellite and ground-based observations. We then examine variations in these measurements relative to their meteorological context. Details of plans for future voyages are also detailed. We will also present a preliminary analysis of a case study of

This species, which occurs throughout the tropics and substropics of the world, is found abundantly in the northern Cape, Swaziland, northern Natal, Transvaal and northwards through South West Africa/Namibia and Botswana. Thoughout its wide distribution the species is uniform. A scrutiny o f herbarium specimens revealed that what appeared as a distinct species or subspecies was without doubt an abnormality, probably caused by insect injury.

    Full Text Available The herpetofauna of the southern Kalahari has mixed affinities, as this area lies on a rainfall gradient in a critical area where a transition between the arid south-west and the moister north-east takes place. As the variation in substrate type is relatively limited, the effect of the rainfall gradient appears to influence and determine the range limits of many taxa in both directions, resulting in an area in which of 55 recorded reptiles, 11 western taxa overlap or form a parapatric zone with 25 eastern taxa, while the remaining taxa are endemic or wideranging.

    With low annual rainfall and high potential of evaporation in southern districts of Tamil Nadu, it is difficult to grow the crops, successfully. Drylands of this tract are vulnerable to high radiation, high temperature and variable rainfall. Hence, dryfarming has become a risky enterprise in this zone and all the above factors altogether reduce the choice of agricultural crops. Considering the magnitude of the area and it's untapped potential, which offers enormous scope for dryland horticulture in this region and thereby improving the soil productivity for other crops too

    Full Text Available Abstract Background The present paper is a brief survey on the ethnobotanical works published by the Authors since 1981, concerning the research carried out in some southern and central Italian regions. Before Roman domination these territories were first inhabited by local people, while the southern areas were colonized by the Greeks. These different cultural contributions left certain traces, both in the toponyms and in the vernacular names of the plants and, more generally, in the culture as a whole. Methods Field data were collected through open interviews, mainly of farmers, shepherds and elderly people, born or living in these areas for a long time. Voucher specimens of collected plants are preserved in the respective herbaria of the Authors and in the herbarium of "Roma Tre" University. Important contributions have been made by several students native to the areas under consideration. A comparative analysis with local specific ethnobotanical literature was carried out. Results The paper reports several examples concerning human and veterinary popular medicine and in addition some anti-parasitic, nutraceutic, dye and miscellaneous uses are also described. Moreover vernacular names and toponyms are cited. Eight regions of central and southern Italy (particularly Latium, Abruzzo, Marche and Basilicata were investigated and the data obtained are presented in 32 papers. Most of the species of ethnobotanical interest have been listed in Latium (368 species, Marche (274 and Abruzzo (203. The paper also highlights particularly interesting aspects or uses not previously described in the specific ethnobotanical literature. Conclusion Phyto-therapy in central and southern Italy is nowadays practised by a few elderly people who resort to medicinal plants only for mild complaints (on the contrary food uses are still commonly practised. Nowadays therapeutic uses, unlike in the past, are less closely or not at all linked to ritual aspects. Several

    With the launch of the South African National Laser Centre, new programs will need to be defined. Medical, environmental and industrial laser applications must obviously take top priority -- as opposed to the uranium isotope separation and military applications of the past. We argue however, that a small effort in laser ablation for space propulsion is justifiable, since a few very large CO2 lasers are available and since two tentative propulsion experiments have already been conducted in South Africa. We attempt to give LISP (Laser Impulse Space Propulsion) an equatorial and a Southern dimension.

    The spread of rabies since 1950 in Southern Rhodesia is described, and its probable causes analysed; the outbreak is attributed chiefly to the vast domestic-dog population, but cases have been noted among many other species of animal. The difficulties encountered in enforcing general control measures are discussed; however, the advent of Flury-strain avianized vaccine has allowed of a successful inoculation campaign which, in spite of some failure in immunization, is satisfactorily controlling the disease in most of the areas involved.

    The Southern Annular Mode (SAM) is the main driver of climate variability at mid to high latitudes in the Southern Hemisphere, affecting wildfire activity, which in turn pollutes the air and contributes to human health problems and mortality, and potentially provides strong feedback to the climate system through emissions and land cover changes. Here we report the largest Southern Hemisphere network of annually resolved tree ring fire histories, consisting of 1,767 fire-scarred trees from 97 sites (from 22 °S to 54 °S) in southern South America (SAS), to quantify the coupling of SAM and regional wildfire variability using recently created multicentury proxy indices of SAM for the years 1531-2010 AD. We show that at interannual time scales, as well as at multidecadal time scales across 37-54 °S, latitudinal gradient elevated wildfire activity is synchronous with positive phases of the SAM over the years 1665-1995. Positive phases of the SAM are associated primarily with warm conditions in these biomass-rich forests, in which widespread fire activity depends on fuel desiccation. Climate modeling studies indicate that greenhouse gases will force SAM into its positive phase even if stratospheric ozone returns to normal levels, so that climate conditions conducive to widespread fire activity in SAS will continue throughout the 21st century.

    To estimate the seroprevalence of human leptospirosis in southern Vietnam. All pupils (n=961) of two primary schools in two communes in southern Vietnam were screened for the presence of serum Leptospira immunoglobulin (Ig)G. Leptospira IgM was tested in 92 randomly selected samples. IgM and IgG were tested with a commercially available enzyme-linked immunosorbent assay (ELISA). Leptospira IgG was found in 123 (12.8%, 95% CI: 10.8-15.1) children with a male:female ratio of 1.5:1. At the age of 7 years the prevalence was 11%. Log-linear binary regression of the IgG seroprevalence by age showed a mean seroconversion rate of 1.5% (95% CI: 1.23-1.75) per year. Five (5.4%, 95% CI: 2.3-12.1) samples were definitely positive for IgM. Presence of serum Leptospira IgG antibodies was significantly associated with swimming in rivers (RR: 1.745, 95% CI: 1.117-2.724) and wading through water (RR 1.793, 95% CI: 1.181-2.722). Our data emphasize the importance of leptospirosis among children in Vietnam, despite the absence of severe disease, and stress the need for adequate and cheap diagnostics.

    We present early results from the SOAR + SMARTS Southern White Dwarf SURVEY (SSSWDS). Our initial sift of relatively bright (15 color relation of Oppenheimer et al. 2001 are obtained and permit prioritized follow-up. For confirmation of luminosity class, we use the SOAR telescope atop Cerro Pachon equipped with the Goodman Spectrograph and a moderate resolution grating. In tandem, we acquire multi-epoch, optical Johnson-Kron-Cousins BVRI photometry using the SMARTS 1.0m telescope atop CTIO. Combined with JHK from 2MASS, we compare the photometric SED to relevant white dwarf model atmospheres to estimate physical parameters (e.g., effective temperature, mass) and distance. For the nearest targets, specifically those within the RECONS (www.recons.org) horizon of 25 pc, we aim to obtain trigonometric parallaxes as part of the Cerro Tololo Inter-American Observatory Parallax Investigation (CTIOPI) project being conducted at the SMARTS 0.9m telescope. To date, we have confirmed 100 relatively bright, new white dwarfs in the southern hemisphere. Of those, 13 are estimated to be within our 25 pc horizon-of-interest, including two that are estimated to be within 15 pc. Ongoing observations will boost these figures by the end of the project.

    Cooling-tower water is a critical utility for many industries. In the past, inexpensive water coupled with moderate regulation of discharge water led to the neglect of the cooling tower as an energy resource. Now, with the increased cost of chemical treatment and tough EPA rules and regulations, this situation is rapidly changing. The operator of the DOE Y-12 Plant in Oak Ridge as well as many other industries are forced to develop an alternate method of water treatment. The cooling tower is one of the major elements in large energy systems. The savings accrued from a well engineered cooling tower can be a significant part of the overall energy conservation plan. During a short-term ozonation study between 1987-1988, the Y-12 Plant has been successful in eliminating the need for cooling tower treatment chemicals. However, the long-term impact was not available. Since April 1988, the ozone cooling water treatment study at the Y-12 Plant has been moved to the site at Southern University in Baton Rouge, Louisiana. The purpose of this continued study is to determine whether the use of ozonation on cooling towers is practical from an economic, technical and environmental standpoint. This paper discusses system design, operating parameter and performance testing of the ozonation system at Southern University

    The fundamental objectives of this study were to review and improve the seismological data base as an aid in more realistic evaluation of seismic hazard in southern Ontario. For this purpose, the following procedures have been undertaken: In the first stage, the types of errors in earthquake location files are identified, sources of uncertainties are discussed and a sensitivity analysis of the errors to different parameters is presented. In the second stage, a group location technique, Joint Hypocenter Determination (JHD), has been utilized to improve the locations of a group of 67 well-recorded events, mostly from the more active region near the Ottawa River and in western Quebec. The third stage, to relocate smaller and less reliably detected events in southern Ontario, utilized a nw algorithm, 'HYPOCENTER', which proved very efficient and flexible in the test runs for handling local explosion and natural events. A preliminary interpretation of the seismicity patterns in the study regions shows that earthquakes of magnitude 3 and larger tend to align along preferred seismic trends which may, in turn, be controlled by weakness planes in the Earth's crust. These inferred trends coincide with dominant northwesterly and northeasterly striking structural directions. For earthquakes smaller than magnitude 4 prior to 1970 and for microearthquakes (M<3) which occurred near the Lake Ontario shoreline, the detection coverage was not sufficient to conclusively discuss accurate locations and causative mechanisms

  17. Megaliths and Neolithic astronomy in southern Egypt

    The Sahara west of the Nile in southern Egypt was hyperarid and unoccupied during most of the Late Pleistocene epoch. About 11,000 years ago the summer monsoons of central Africa moved into Egypt, and temporary lakes or playas were formed. The Nabta Playa depression, which is one of the largest in southern Egypt, is a kidney-shaped basin of roughly 10km by 7km in area. We report the discovery of megalithic alignments and stone circles next to locations of Middle and Late Neolithic communities at Nabta, which suggest the early development of a complex society. The southward shift of the monsoons in the Late Neolithic age rendered the area once again hyperarid and uninhabitable some 4,800 radiocarbon years before the present (years BP). This well-determined date establishes that the ceremonial complex of Nabta, which has alignments to cardinal and solstitial directions, was a very early megalithic expression of ideology and astronomy. Five megalithic alignments within the playa deposits radiate outwards from megalithic structures, which may have been funerary structures. The organization of the megaliths suggests a symbolic geometry that integrated death, water, and the Sun. An exodus from the Nubian Desert at ~4,800 years BP may have stimulated social differentiation and cultural complexity in predynastic Upper Egypt.

  18. New Perspectives on Southern Ocean Frontal Variability

    2017-04-01

    The frontal structure of the Southern Ocean is investigated using a the Wavelet/Higher Order Statistics Enhancement (WHOSE) frontal detection method, introduced in Chapman (2014). This methodology is applied to 21 years of daily gridded sea-surface height (SSH) data to obtain daily maps of the locations of the fronts. By forming frontal occurrence frequency maps and then approximating these occurrence-maps by a superposition of simple functions, the time-mean locations of the fronts, as well as a measure of their capacity to meander, are obtained and related to the frontal locations found by previous studies. The spatial and temporal variability of the frontal structure is then considered. The number of fronts is found to be highly variable throughout the Southern Ocean, increasing (`splitting') downstream of large bathymetric features and decreasing (`merging') in regions where the fronts are tightly controlled by the underlying topography. In contrast, frontal meandering remains relatively constant. Contrary to many previous studies, little no southward migration of the fronts over the 1993-2014 time period is found, and there is only weak sensitivity to atmospheric forcing related to SAM or ENSO. Finally, the implications of splitting and merging for the flux of tracers will be discussed.

  19. Climate change induced by Southern Hemisphere desertification

    Some 10-20% of global dry-lands are already degraded, and the ongoing desertification threatens the world's poorest populations. Studies on desertification effects are essential for humans to adapt to the environmental challenges posed by desertification. Given the importance of the much larger southern ocean to the global climate and the Southern Hemisphere (SH) climate changes in phase with those in the north, the biogeophysical effects of the SH desertification on climate are assessed using an Earth system model of intermediate complexity, MPM-2. This analysis focuses on differences in climate among the averages of simulations with desert expansion in different latitude bands by year 2000. The localized desertification causes significant global changes in temperature and precipitation as well as surface albedo. On the global scale, cooling dominates the SH desertification effects. However, the biogeophysical effects are most significant in regions with desertification, and the cooling is also prominent in northern mid-latitudes. Desert expansion in 15°-30°S reveals statistically most significant cooling and increased precipitation over the forcing regions during spring. The global and regional scale responses from desertification imply the climate teleconnection and address the importance of the effects from the SH which are contingent on the location of the forcing. Our study indicates that biogeophysical mechanisms of land cover changes in the SH need to be accounted for in the assessment of land management options especially for latitude band over 15°-30°S.

    Full Text Available The observed and projected changes in the climate of southern Africa in the period 1900–2100 were analysed. Ten observed, reanalysed and model-simulated climate data sets were explored for changes in surface air temperature, rainfall, air pressure, winds, ocean currents and sea surface height. The analysis of spatial and temporal climate trends from historical observations provided a context to assess two coupled model simulations (IPSL, MIROC based on the A1B emission scenario. Temperatures in the satellite era exhibited upward trends greater than +0.4 °C/year in the MIROC and IPSL A1B model simulations; between +0.02 °C/year and +0.03 °C/year in NCDC, HADCRU, CFS-R and NCEPe data sets; +0.01 °C/year in NCEPr and GHCN observations; and +0.002 °C/year in the ECMWF data set. Although rainfall trends in the satellite era were minimal in many data sets because of drought in the early 1980s, there was a significant downtrend in the IPSL simulation of -0.013 mm/day per year. When averaging the longer data sets together over the 20th century, the southern African rainfall trend was -0.003 mm/day per year. Other key features of the analyses include a poleward drift of the sub-tropical anticyclones and a +1.5 mm/year rise in sea surface height along the coast.

    The accumulation of large boulders related to extreme waves are well documented in different areas of the Mediterranean coasts, such as in Turkey, Algeria, Egypt, Greece (Lesbos and Crete islands), France, Spain, Malta, Italy (Sicily and Apulia regions). These deposits have been associated to storm or tsunami events or both, depending on the local history. If compared to the Mediterranean Sea, the Adriatic Sea is considered a shallow basin, with very low wave energy. In particular the NE Adriatic, where Istria Peninsula (Croatia) is located, geological and geomorphological evidences of extreme wave events have never been described, as well as no tsunamis have been registered. We present the boulder deposits that have been recently found out in southern Istria, at Premantura and Marlera localities and we discuss the mechanisms that could have been responsible of the detachment and movement of these large rocky blocks from the emerged part of the coast and from the sea bottom inland. A multidisciplinary approach was adopted: geological and geomorphological surveyings, UAV and digital photogrammetric analysis, applying of the hydrodynamic equations as well as underwater profiles were carried out between 2012 and 2016. The southern Istrian coasts are composed of Cretaceous bedded limestones, sub-horizontal or gently inclined toward the sea and are exposed to southern winds, Scirocco and Libeccio, with wide fetch. The boulder deposits occur in correspondence of flat promontories or ancient quarry pavements, where the topography, together with the bedding planes and a dense fracture pattern constitute the predisposing factors of the boulder sizing and detachment. Boulder sizes, density, position and elevation have been measured in order to apply the hydrodynamic equations, which provide wave height values that can discriminate a storm from a tsunami origin. Biogenic marine encrustations, sometimes very recent, have been observed on large part of the boulders, attesting

    The stabilized linear dunefields in the southern Kalahari show signs of reactivation due to reduced vegetation cover owing to drought and/or overgrazing. It has been demonstrated with a laboratory dust generator that the southern Kalahari soils are good emitters of dust and that large-scale dune reactivation can potentially make the region an important dust source in the relatively low-dust Southern Hemisphere. We show that emergence of the southern Kalahari as a new dust source may affect ocean biogeochemistry as the soils are rich in soluble iron and the dust from the southern Kalahari commonly reaches the Southern Ocean. We investigate the biogeochemical properties of the fine fraction of soil from the Kalahari dunes and compare them to those of currently active dust sources such as the Makgadikgadi and the Etosha pans as well as other smaller pans in the region. Using field measurements of sediment fluxes and satellite images, we calculate the rates of dust emission from the southern Kalahari under different land cover scenarios. To assess the reversibility of dune reactivation in the southern Kalahari, we investigate the resilience of dunefield vegetation by looking at changes in soil nutrients, fine soil fractions, and seed bank in areas affected by intense denudation.

    2001-01-01

    Four case studies involving the use of the environmental isotopes 14 C and 3 H, in the and to semi-arid Kalahari region of Southern Africa are described and general conclusions regarding the qualitative aspects of recharge and discharge characteristics of the systems are based on these measurements. In each of the studies, diffuse, local recharge was found to be the dominant recharge mechanism. Recharge via river beds was found to be limited at the regional scale. The balancing discharge mechanism for groundwater was found to be via evapotranspiration. Groundwater salinity and mineralisation as well as the regional hydrogeology are controlled by geological structure rather than lithologies or residence times and the absence of hypersaline groundwaters indicates that the aquifers are periodically flushed during pluvial periods, thus pointing to long-term hydroclimatic controls over the observed present-day hydrology.

  2. [Toxicity and apple production in southern Brazil].

    Science.gov (United States)

    Klanovicz, Jó

    2010-03-01

    The article explores the links between the controversial apprehension of contaminated apples in southern Brazil in 1989 and the reactions of the apple industry to press reports on the use of pesticides in Brazilian orchards. The issue is framed within a broader analysis of the notions of toxicity and 'danger' surrounding the consumption of healthier food and the idea of 'food security,' notions that have begun taking hold in public and private life. It is argued that apple growers' responses to the problem can be better understood through a historical reading of the interactions between the biology of the apple tree, the agroecology of this monoculture, and the structures, actors, and discourses of the human and non-human groups in Brazil's apple-producing region.

  3. Brazil to Join the European Southern Observatory

    Science.gov (United States)

    2010-12-01

    The Federative Republic of Brazil has yesterday signed the formal accession agreement paving the way for it to become a Member State of the European Southern Observatory (ESO). Following government ratification Brazil will become the fifteenth Member State and the first from outside Europe. On 29 December 2010, at a ceremony in Brasilia, the Brazilian Minister of Science and Technology, Sergio Machado Rezende and the ESO Director General, Tim de Zeeuw signed the formal accession agreement aiming to make Brazil a Member State of the European Southern Observatory. Brazil will become the fifteen Member State and the first from outside Europe. Since the agreement means accession to an international convention, the agreement must now be submitted to the Brazilian Parliament for ratification [1]. The signing of the agreement followed the unanimous approval by the ESO Council during an extraordinary meeting on 21 December 2010. "Joining ESO will give new impetus to the development of science, technology and innovation in Brazil as part of the considerable efforts our government is making to keep the country advancing in these strategic areas," says Rezende. The European Southern Observatory has a long history of successful involvement with South America, ever since Chile was selected as the best site for its observatories in 1963. Until now, however, no non-European country has joined ESO as a Member State. "The membership of Brazil will give the vibrant Brazilian astronomical community full access to the most productive observatory in the world and open up opportunities for Brazilian high-tech industry to contribute to the European Extremely Large Telescope project. It will also bring new resources and skills to the organisation at the right time for them to make a major contribution to this exciting project," adds ESO Director General, Tim de Zeeuw.

    The etiology of fever in rural Lao People's Democratic Republic (Laos) has remained obscure until recently owing to the lack of laboratory facilities. We conducted a study to determine the causes of fever among 229 patients without malaria in Savannakhet Province, southern Laos; 52% had evidence of at least one diagnosis (45% with single and 7% with apparent multiple infections). Among patients with only one diagnosis, dengue (30.1%) was the most common, followed by leptospirosis (7.0%), Japanese encephalitis virus infection (3.5%), scrub typhus (2.6%), spotted fever group infection (0.9%), unspecified flavivirus infection (0.9%), and murine typhus (0.4%). We discuss the empirical treatment of fever in relation to these findings. © The American Society of Tropical Medicine and Hygiene.

    In May 2003, the World Health Organization received reports about a possible outbreak of a hemorrhagic disease of unknown cause in the Imatong Mountains of southern Sudan. Laboratory investigations were conducted on 28 serum samples collected from patients in the Imatong region. Serum samples from 13 patients were positive for immunoglobulin M antibody to flavivirus, and serum samples from 5 patients were positive by reverse transcription–polymerase chain reaction with both the genus Flavivirus–reactive primers and yellow fever virus–specific primers. Nucleotide sequencing of the amplicons obtained with the genus Flavivirus oligonucleotide primers confirmed yellow fever virus as the etiologic agent. Isolation attempts in newborn mice and Vero cells from the samples yielded virus isolates from five patients. Rapid and accurate laboratory diagnosis enabled an interagency emergency task force to initiate a targeted vaccination campaign to control the outbreak. PMID:15207058

    1985-08-01

    Thyroid stimulating hormone (TSH) determination by a radioimmunoassay on dried blood spots was selected as the screening method for congenital hypothyroidism in Southern Thailand. Blood from the infant's heel was obtained in 7814 newborns on the fifth day of life. Infants with TSH values greater than 25 mU/L were recalled for a more careful clinical examination and to have their T4 (thyroxine) and TSH re-estimated. Fifty-four infants with TSH values between 25 and 50 mU/L were found to be normal at re-evaluation. These are still being followed longitudinally for full confirmation. Two with values above 50 mU/L, although clinically euthyroid, were found to be hypothyroid by T3, T4, thyroid scintigraphy and bone age on roentgenography. Replacement therapy has been started. We have shown that a screening program for neonatal hypothyroidism can be done, and is probably worthwhile and perhaps even cost-effective

    In November of 1989, the US Nuclear Regulatory Commission (NRC) conducted an electrical safety system functional inspection (ESSFI) at the San Onofre nuclear generating station (SONGS), which was followed by an NRC audit on instrument setpoint methodology in January 1991. Units 2 and 3 at SONGS are 1100-MW(electric) Combustion Engineering (C-E) pressurized water reactors (PWRs) operated by Southern California Edison (SCE). The purpose of this paper is to summarize the results of the NRC audit and SCE's follow-up activities. The NRC team inspection reinforced the need to address several areas relative to the SCE setpoint program. The calculations withstood the intensive examination of four NRC inspectors for 2 weeks and only a few minor editorial-type problems were noted. Not one of the calculated plant protections system setpoints will change as a result of the audit. There were no questions raised relative to setpoint methodology

    Law, Nicholas M.; Ziegler, Carl; Tokovinin, Andrei

    2016-08-01

    We present plans for SRAO, the first Southern Robotic AO system. SRAO will use AO-assisted speckle imaging and Robo-AO-heritage high efficiency observing to confirm and characterize thousands of planet candidates produced by major new transit surveys like TESS, and is the first AO system to be capable of building a comprehensive several-thousand-target multiplicity survey at sub-AU scales across the main sequence. We will also describe results from Robo-AO, the first robotic LGS-AO system. Robo-AO has observed tens of thousands of Northern targets, often using a similar speckle or Lucky-Imaging assisted mode. SRAO will be a moderate-order natural-guide-star adaptive optics system which uses an innovative photoncounting wavefront sensor and EMCCD speckle-imaging camera to guide on faint stars with the 4.1m SOAR telescope. The system will produce diffraction-limited imaging in the NIR on targets as faint as mν = 16. In AO-assisted speckle imaging mode the system will attain the 30-mas visible diffraction limit on targets at least as faint as mν = 17. The system will be the first Southern hemisphere robotic adaptive optics system, with overheads an order of magnitude smaller than comparable systems. Using Robo-AO's proven robotic AO software, SRAO will be capable of observing overheads on sub-minute scales, allowing the observation of at least 200 targets per night. SRAO will attain three times the angular resolution of the Palomar Robo-AO system in the visible.

    High-resolution spectroscopic observations have been made of a number of southern binary Cepheids to determine their dynamical masses. The stars are part of a long-term program to observe southern variable starsf or which a valuable long-term database has been obtained. The most recent radial velocities have a precision of ~300 ms-1, allowing the detection of velocity differences of ~1 kms-1 with confidence. Masses were determined for three systems: the 9-day Cepheid S Mus (6.0±0.4 MSolar), the double-mode Cepheid Y Car (4.5±1.8 MSolar) and the 5-day Cepheid V350 Sgr (6.0±0.9 MSolar). For five Cepheids (YZ Car, AX Cir, V636 Sco, W Sgr and T Mon) new or improved orbital solutions were found. Line level effects have been observed in several species of lines. Most Cepheids were observed to show the same progression of line level effects. Using non-linear radiative hydrodynamical models, we have compared the results of these models with our observations. These have shown that AX Cir and YZ Car have the following properties: L = 2050 LSolar, M = 4.8 MSolar, Teff = 5900 K and L = 9350 LSolar, M = 7.7 MSolar, Teff = 5590 K. Our models show no strong shockwaves being produced. Good agreement was found between the observed and modelled spectral lines Fe I 5576Å, SiII 6347Å, BaII 5853Å and CaII 8542Å.

  13. Northerners versus southerners: Italian anthropology and psychology faced with the "southern question".

    2014-11-01

    Following the Unification of Italy (1861), when confronted with the underdevelopment problems of the south that had given rise to the so-called "southern question," some Italian anthropologists and psychologists began to study the populations of the south from the psycho-anthropological point of view. These scientists, at times subject to preconceived ideas toward the southerners, conveyed observations and descriptions of the southern character traits that, in general, were considered different, in a negative sense, with respect to those of the northern peoples. To explain such diversity in the "psychological" characteristics between the north and south of the country (presumed cause also of the south's backwardness), various hypotheses were advanced related to the kind of heredity theory adopted, which could be of, more or less, an "innatist" or "transformist" or "environmentalist" kind. The distinction proposed in this article between at least 2 different "hereditarian" theories formulated by the Italian scientists, and the confrontation of these theories with the hypotheses expressed by the "southernist" sociologists, contrary to the idea of "racial varieties" present in the Italian population, allows one to understand in what way and in what sense, at the threshold of the 20th century, there arose the ideology of "Nordicism" and the roots of racism were planted.

    Southern Sudan has been ravaged by decades of conflict and is thought to have one of the highest burdens of neglected tropical diseases (NTDs) in the world. Health care delivery, including efforts to control or eliminate NTDs, is severely hampered by a lack of infrastructure and health systems. However, the post-conflict environment and Southern Sudan's emerging health sector provide the unprecedented opportunity to build new, innovative programmes targeting NTDs. This article describes the current status of NTDs and their control in Southern Sudan and outlines the opportunities for the development of evidence-based, innovative implementation of NTD control.

  16. Stars and Seasons in Southern Africa

    Science.gov (United States)

    Snedegar, K. V.

    Although the indigenous people of Southern Africa traditionally viewed the sky as a place quite apart from the Earth, they believed celestial phenomena to be natural signs united with those of the Earth in a harmonious synchronicity. There is no substantial evidence that the precolonial Africans imagined a casual relationship between celestial bodies and the seasonal patterns of life on Earth. They did, however, recognize a coincidental relationship. The traditional African cosmos, then, worked as a noetic principle unifying the observed motions of celestial bodies, the sequence of seasons, and the behavior of plants and animals. Such a cosmos, with local peculiarities, was widely understood in Southern Africa before the end of the last century. By the early 20th century European colonial paradigms had largely obliterated this African worldview. This paper will offer a partial reconstruction. Pre-colonial South African people viewed time as a sequence of discrete natural events; through annual repetition these events served as a guide for proper human action. The South Africans analyzed the passage of time in terms of the motions of celestial bodies, the maturation of beneficial plants, and the mating patterns of animals. The rightful course of human life was seen to fit within the seasonal context of these natural phenomena. The visibility of conspicuous stars and asterisms marked significant times of year. For instance, the Lovedu people greeted the dawn rising of Canopus with joy: "The boy has come out." The star was a signal for rainmaking and boys' initiation ceremonies to proceed. The Venda constellation Thutlwa, the giraffes, comprises α and β Crucis and α and β Centauri. In October Thutlwa skims the trees of the evening horizon. The Venda Thutlwa literally means 'rising above the trees,' an allusion to the majestic vegetarian creatures and the stars advising the people to be done with their spring planting. This paper will describe stellar associations

    Transport of carbonyl sulfide (OCS) from the troposphere to the stratosphere contributes sulfur to the stratospheric aerosol layer, which reflects incoming short-wave solar radiation, cooling the climate system. Previous analyses of OCS observations have shown no significant trend, suggesting that OCS is unlikely to be a major contributor to the reported increases in stratospheric aerosol loading and indicating a balanced OCS budget. Here we present analyses of ground-based Fourier transform spectrometer measurements of OCS at three Southern Hemisphere sites spanning 34.45°S to 77.80°S. At all three sites statistically significant positive trends are seen from 2001 to 2014 with an observed overall trend in total column OCS at Wollongong of 0.73 ± 0.03%/yr, at Lauder of 0.43 ± 0.02%/yr, and at Arrival Heights of 0.45 ± 0.05%/yr. These observed trends in OCS imply that the OCS budget is not balanced and could contribute to constraints on current estimates of sources and sinks.

    EOS Space Systems (EOSSS) is a research and development company which has developed custom observatories, camera and telescope systems for space surveillance since 1996, as well as creating several evolutions of systems control software for control of observatories and laser tracking systems. Our primary reserach observatory is the Space Reserach Centre (SRC) at Mount Stromlo Asutralia. The current SRC control systems are designed such that remote control can be offered for real time data collection, noise filtering and flexible session management. Several imaging fields of view are available simultaneously for tracking orbiting objects, with real time imaging to Mag 18. Orbiting objects can have the centroids post processed into orbital determination/ orbital projection (OD/OP) elements. With or without laser tracking of orbiting objects, they can be tracked in terminator conditions and their OD/OP data created, then enhanced by proprietary methods involving ballistic coefficient estimation and OD convergence pinning, using a priori radar elements. Sensors in development include a thermal imager for satellite thermal signature detection. Extending laser tracking range by use of adaptive optics beam control is also in development now. This Southern Hemisphere observatory is in a unique position to facilitate the study of space debris, either stand-alone or as part of a network such as Falcon. Current national and international contracts will enhance the remote control capabilities further, creating a resource ready to go for a wide variety of SSA missions.

    The Southern Regional Center for Lightweight Innovative Design (SRCLID) has developed an experimentally validated cradle-to-grave modeling and simulation effort to optimize automotive components in order to decrease weight and cost, yet increase performance and safety in crash scenarios. In summary, the three major objectives of this project are accomplished: To develop experimentally validated cradle-to-grave modeling and simulation tools to optimize automotive and truck components for lightweighting materials (aluminum, steel, and Mg alloys and polymer-based composites) with consideration of uncertainty to decrease weight and cost, yet increase the performance and safety in impact scenarios; To develop multiscale computational models that quantify microstructure-property relations by evaluating various length scales, from the atomic through component levels, for each step of the manufacturing process for vehicles; and To develop an integrated K-12 educational program to educate students on lightweighting designs and impact scenarios. In this final report, we divided the content into two parts: the first part contains the development of building blocks for the project, including materials and process models, process-structure-property (PSP) relationship, and experimental validation capabilities; the second part presents the demonstration task for Mg front-end work associated with USAMP projects.

    Full Text Available The aim of this research was to survey current mechanization level of coppice harvesting in Southern Italy. The cooperation of the General Direction of the National Forest Service (NFS has been a basic tool of survey. A questionnaire compiled on purpose was sent to each Forest Station (hereinafter referred to as CS in the following regions: Basilicata, Campania and Calabria. A high percentage (80% of the CSs did fulfill the questionnaire. The answers highlight that: i the main assortment currently produced is firewood; ii the level of harvesting mechanization is rather low, equipment being quite obsolete: indeed, the most widely used machineries are farm tractors partly adapted to forest harvesting and equipped with cages or back winch; iii the use of animals for hauling (mules and oxen, the latter in Calabria is still quite frequent, while forest tractors, polyethylene chutes and cable cranes are almost absent; iv the use of individual protection (DPI and machinery protection devices (DPM is on average quite low.

    Little is known about pyrethroid fate and effects in estuarine and marine environments. In the present study, the extent and magnitude of pyrethroids in coastal embayments of the Southern California Bight (SCB), USA, were assessed. Using a stratified probabilistic design, 155 sediment samples were collected from four embayment habitats (estuaries, marinas, open bays, and ports) and analyzed for eight common-use pyrethroids. Total pyrethroid concentrations ranged from less than 0.5 to 230 µg/kg dry weight (area-weighted mean concentration=5.1 ± 3.1 µg/kg) and were detected in 35% of the total SCB embayment area. Estuaries and marinas had the greatest areal extent of detectable concentrations (up to 65%) and the greatest area-weighted mean concentrations (22.1 ± 26.5 µg/kg). Sites with the greatest pyrethroid concentrations were located near sources of runoff from urban watersheds. Bifenthrin and cyfluthrin were detected in 32 and 15% of all samples, respectively, whereas the other six pyrethroids were detected in ≤ 5% of samples. Permethrin and bifenthrin had the highest concentrations at 132 and 65 µg/kg. Toxic units estimated for the marine amphipod Eohaustorius estuarius ranged from 0 to 5.8, exceeding unity in 9 and 32% of the total and estuary habitat areas, respectively, and were not correlated with mortality, suggesting that other factors (e.g., co-occurring contaminants, reduced bioavailability) may affect the predictive capability using a single test species.

  2. Southern Clusters for Standardizing CCD Photometry

    2017-06-01

    Standardizing photometric measurements typically involves undertaking all-sky photometry. This can be laborious and time-consuming and, for CCD photometry, particularly challenging. Transforming photometry to a standard system is, however, a crucial step when routinely measuring variable stars, as it allows photoelectric measurements from different observers to be combined. For observers in the northern hemisphere, standardized UBVRI values of stars in open clusters such as M67 and NGC 7790 have been established, greatly facilitating quick and accurate transformation of CCD measurements. Recently the AAVSO added the cluster NGC 3532 for southern hemisphere observers to similarly standardize their photometry. The availability of NGC 3532 standards was announced on the AAVSO Variable Star Observing, Photometry forum on 27 October 2016. Published photometry, along with some new measurements by the author, provide a means of checking these NGC 3532 standards which were determined through the AAVSO's Bright Star Monitor (BSM) program (see: https://www.aavso.org/aavsonet-epoch-photometry-database). New measurements of selected stars in the open clusters M25 and NGC 6067 are also included.

    Multi-aperture photometry of 262 bright southern galaxies in the Johnson UBV system is given. Most of these are south of delta = -30 0 , although some northward to delta = -10 0 are included. A total of 169 objects have published radial velocity determinations. These provide distances, and enable construction of colour-magnitude diagrams for this subset of objects througha physical diameter of 2.0 kpc (with H 0 = 100). The two-colour diagrams for the inner regions of the galaxies differ from those of integrated galaxies due to the colour changes towards their centres. Comparison with theoretical models of Larson and Tinsley (1978) suggest that the colours of the inner portions of most ellipticals and lenticulars are consistent with their having all stars formed at nearly one epoch with little subsequent star formation, while for spirals larger amounts of star formation, either in bursts of continuously, are suggested. This simple picture is complicated by the presence of certain objects having peculiar colours indicative of large amounts of recent star formation. (Auth.)

    The surface mass balance of the Greenland ice sheet has decreased in recent decades with important implications for global sea level rise. Here a climate reanalysis model is used to examine observed circulation variability and changes in precipitation across southern Greenland to gain insight into the future climate in the region. The influence on precipitation from the North Atlantic Oscillation (NAO), Atlantic Multidecadal Oscillation (AMO), Icelandic Low, Azores High, regional blocking patterns, and near-surface temperature and winds are explored. Statistically significant correlations are higher between precipitation and the Icelandic Low and near-surface winds (0.5-0.7; p < 0.05) than correlations between precipitation and either the NAO or AMO climate indices (southwest Greenland: r = 0.12 and 0.28, respectively; and southeast Greenland: r = 0.25 and -0.07, respectively). Moreover, the recent enhanced warming in the Arctic (Arctic amplification) and the increase in the Greenland Blocking Index coincide with increased mean annual precipitation and interannual variability in southwest Greenland.

    To review a regional experience with the treatment of snakebites. Five major southern Arizona hospitals, including two Level I trauma centers. A review of all snakebite admissions over a five-year period was performed. During the period reviewed, 164 patients were admitted for snakebites. Rattlesnakes were responsible for 98 percent of identified envenomations. Thirty-six percent of the patients were transported by air to the admitting facility. Eighty percent of patients were admitted to the intensive care unit for an average of 1.6 days. Total hospital stays averaged 2.8 days. Ninety percent of patients received antivenin, usually only on the day of admission. Of those receiving antivenin, 20 percent had an anaphylactoid reaction, and 1 percent required readmission for serum sickness. Laboratory evaluation indicated abnormalities in platelet count, coagulation parameters, and fibrinogen levels, but these rarely required treatment. Thirteen percent of patients underwent surgical intervention, including a 4 percent fasciotomy rate, and a single amputation. The use of field treatment, including "cut and suck," tourniquets, and cryotherapy, increased the likelihood of surgery. The authors concluded that the intensive care unit and helicopter transport system were overused. They recommend that established objective envenomation severity scores be used to dictate patient treatment, specifically the use of antivenin.

    Full Text Available This paper aimed to describe milk production in Southern Rio Grande do Sul state, Brazil, and to identify factors that affect milk quality at this region. The average age of regional dairy farmers is 49, and 67.9% has not concluded elementary school. Dairy farming is carried out on properties with an average of 26.06 hectares and 8.4 lactating cows. Most of them (32.83% yield 50 to 100 L/day. Among the properties, 13.21% yield up to 30 L/day, and only 1.89% produces over 500 milk liters a day. Average yield was 6.8 L/day. Regarding to milking procedure, 39.3% farmers milk manually the animals, only 14.2% performed pre-milking teat disinfection, and 53.9% uses a single cloth to dry all animal teats. For infrastructure, 52.8% milks animals in wooden cowsheds. We observed that the average somatic cell count (SCC was within legal parameters, presenting negative correlation with milk production (r = -0.23 and lactose content (r = -0.39. However, the total bacterial count (TBC was above legal parameters. Education level seems to interfere in management and milk quality, because the less educated groups are, the less adequate are infrastructure, management, and product quality. Data show that there is a lower quality milk production where poor management techniques are adopted and owner education level affects milk quality.

    Contaminant loading associated with stormwater runoff from recently burned areas is poorly understood, despite the fact that it has the potential to affect downstream water quality. The goal of the present study is to assess regional patterns of runoff and contaminant loading from wildfires in urban fringe areas of southern California. Postfire stormwater runoff was sampled from five wildfires that each burned between 115 and 658 km(2) of natural open space between 2003 and 2009. Between two and five storm events were sampled per site over the first one to two years following the fires for basic constituents, metals, nutrients, total suspended solids, and polycyclic aromatic hydrocarbons (PAHs). Results were compared to data from 16 unburned natural areas and six developed sites. Mean copper, lead, and zinc flux (kg/km(2)) were between 112- and 736-fold higher from burned catchments and total phosphorus was up to 921-fold higher compared to unburned natural areas. Polycyclic aromatic hydrocarbon flux was four times greater from burned areas than from adjacent urban areas. Ash fallout on nearby unburned watersheds also resulted in a threefold increase in metals and PAHs. Attenuation of elevated concentration and flux values appears to be driven mainly by rainfall magnitude. Contaminant loading from burned landscapes has the potential to be a substantial contribution to the total annual load to downstream areas in the first several years following fires.

  8. Wastewater effluent dispersal in Southern California Bays

    2014-03-01

    The dispersal and dilution of urban wastewater effluents from offshore, subsurface outfalls is simulated with a comprehensive circulation model with downscaling in nested grid configurations for San Pedro and Santa Monica Bays in Southern California during Fall of 2006. The circulation is comprised of mean persistent currents, mesoscale and submesoscale eddies, and tides. Effluent volume inflow rates at Huntington Beach and Hyperion are specified, and both their present outfall locations and alternative nearshore diversion sites are assessed. The effluent tracer concentration fields are highly intermittent mainly due to eddy currents, and their probability distribution functions have long tails of high concentration. The dilution rate is controlled by submesoscale stirring and straining in tracer filaments. The dominant dispersal pattern is alongshore in both directions, approximately along isobaths, over distances of more than 10. km before dilution takes over.

    Northwest directed slip from the southern San Andreas Fault is transferred to the Mission Creek, Banning, and Garnet Hill fault strands in the northwestern Coachella Valley. How slip is partitioned between these three faults is critical to southern California seismic hazard estimates but is poorly understood. In this paper, we report the first slip rate measured for the Banning fault strand. We constrain the depositional age of an alluvial fan offset 25 ± 5 m from its source by the Banning strand to between 5.1 ± 0.4 ka (95% confidence interval (CI)) and 6.4 + 3.7/-2.1 ka (95% CI) using U-series dating of pedogenic carbonate clast coatings and 10Be cosmogenic nuclide exposure dating of surface clasts. We calculate a Holocene geologic slip rate for the Banning strand of 3.9 + 2.3/-1.6 mm/yr (median, 95% CI) to 4.9 + 1.0/-0.9 mm/yr (median, 95% CI). This rate represents only 25-35% of the total slip accommodated by this section of the southern San Andreas Fault, suggesting a model in which slip is less concentrated on the Banning strand than previously thought. In rejecting the possibility that the Banning strand is the dominant structure, our results highlight an even greater need for slip rate and paleoseismic measurements along faults in the northwestern Coachella Valley in order to test the validity of current earthquake hazard models. In addition, our comparison of ages measured with U-series and 10Be exposure dating demonstrates the importance of using multiple geochronometers when estimating the depositional age of alluvial landforms.

How slip is partitioned between these three faults is critical to southern California seismic hazard estimates but is poorly understood. In this paper, we report the first slip rate measured for the Banning fault strand. We constrain the depositional age of an alluvial fan offset 25 ± 5 m from its source by the Banning strand to between 5.1 ± 0.4 ka (95% confidence interval (CI)) and 6.4 + 3.7/−2.1 ka (95% CI) using U-series dating of pedogenic carbonate clast coatings and 10Be cosmogenic nuclide exposure dating of surface clasts.

    Knowledge of population structure is very important for forensic genetics. However, the population substructure in Central-Southern China Han nationality has still not been fully described. In this study, we investigated the genetic diversity of 15 forensic autosomal STR loci from 6879 individuals in 12 Han populations subdivided by administrative provinces in Central-Southern China. The statistical analysis of genetic variation showed that genetic differentiation among these populations was very small with a F st value of 0.0009. The Discriminant Analysis of Principal Components (DAPC) showed that there were no obvious population clusters in Central-Southern China Han population. In practice, the population structure effect in Central-Southern China Han population can be negligible in forensic identification and paternity testing. Copyright © 2017. Published by Elsevier B.V.

  8. Radioactive fallout in the southern hemisphere from nuclear weapons tests

    International Nuclear Information System (INIS)

    Moroney, J.R.

    1979-11-01

    Fallout in the southern hemisphere, and its origins in the national programs of atmospheric nuclear weapons testing in both hemispheres, are reviewed. Of the 390 nuclear tests conducted in the atmosphere to date, 53 were carried out in the southern hemisphere and it is the second phase of these, between 1966 and 1974, that is seen to have been responsible for the main fallout of short-lived fission products in the southern hemisphere. In contrast to this, the programs of atmospheric nuclear testing in the northern hemisphere up to 1962 are shown to have been the main source of long-lived fission products in fallout in the southern hemisphere. The course followed by this contamination through the environment of the southern hemisphere is traced for the national programs of nuclear testing after 1962 taken separately (France, China) and for the earlier national programs taken together (U.S.S.R., U.S.A. and U.K.). The impact on populations in the southern hemisphere of fallout from atmospheric nuclear weapons tests to date is assessed

  11. Characteristics of Southern California coastal aquifer systems

    Science.gov (United States)

    Edwards, B.D.; Hanson, R.T.; Reichard, E.G.; Johnson, T.A.

    2009-01-01

    Most groundwater produced within coastal Southern California occurs within three main types of siliciclastic basins: (1) deep (>600 m), elongate basins of the Transverse Ranges Physiographic Province, where basin axes and related fluvial systems strike parallel to tectonic structure, (2) deep (>6000 m), broad basins of the Los Angeles and Orange County coastal plains in the northern part of the Peninsular Ranges Physiographic Province, where fluvial systems cut across tectonic structure at high angles, and (3) shallow (75-350 m), relatively narrow fluvial valleys of the generally mountainous southern part of the Peninsular Ranges Physiographic Province in San Diego County. Groundwater pumped for agricultural, industrial, municipal, and private use from coastal aquifers within these basins increased with population growth since the mid-1850s. Despite a significant influx of imported water into the region in recent times, groundwater, although reduced as a component of total consumption, still constitutes a significant component of water supply. Historically, overdraft from the aquifers has caused land surface subsidence, flow between water basins with related migration of groundwater contaminants, as well as seawater intrusion into many shallow coastal aquifers. Although these effects have impacted water quality, most basins, particularly those with deeper aquifer systems, meet or exceed state and national primary and secondary drinking water standards. Municipalities, academicians, and local water and governmental agencies have studied the stratigraphy of these basins intensely since the early 1900s with the goals of understanding and better managing the important groundwater resource. Lack of a coordinated effort, due in part to jurisdictional issues, combined with the application of lithostratigraphic correlation techniques (based primarily on well cuttings coupled with limited borehole geophysics) have produced an often confusing, and occasionally conflicting

    Full Text Available One of the greatest problems observed in Brazilian urban watersheds are concerned to the amount of solid residues, domestic sewerage and sediments that are disposed in the rivers and streams that drain those areas. This project aims to present these problems through a study of case taken in an urban watershed in Porto Alegre city, Southern Brazil. For this study, different procedures were used, such as field surveys, interviews with the inhabitants, satellite images, sediment samples, flow measures and morphology assessment of part of the local fluvial system to check the degree of instability of the channel. In 2005, it was verified that 42.57% of the watershed was impermeable, considering the paved streets, the residential and commercial buildings and stone pavements. As there was no sewer treatment, most of this sewerage was directly disposed into the stream and the TOC has reached 20% (m/m. Moreover, the occupation of riparian areas, a great amount of soil exposed in the watershed, the nonpaved streets and a great volume of solid residues were causing the instability in the channel, silting the stream bed. The metals (Zn, Pb and Cr selected for this study are most frequently found in high concentrations in urban areas. The results suggest the occurrence of a high enrichment of the fluvial sediment by these metals. The concentrations of these elements vary temporally during storms due to the input of impervious area runoff containing high concentration of elements associated to vehicular traffic and other anthropogenic activities. Then, it is possible to conclude that the contamination of the urban watershed is reflected in the results obtained in the fluvial suspended sediments.

    Full Text Available Current evidence of phenological responses to recent climate change is substantially biased towards northern hemisphere temperate regions. Given regional differences in climate change, shifts in phenology will not be uniform across the globe, and conclusions drawn from temperate systems in the northern hemisphere might not be applicable to other regions on the planet. We conduct the largest meta-analysis to date of phenological drivers and trends among southern hemisphere species, assessing 1208 long-term datasets from 89 studies on 347 species. Data were mostly from Australasia (Australia and New Zealand, South America and the Antarctic/subantarctic, and focused primarily on plants and birds. This meta-analysis shows an advance in the timing of spring events (with a strong Australian data bias, although substantial differences in trends were apparent among taxonomic groups and regions. When only statistically significant trends were considered, 82% of terrestrial datasets and 42% of marine datasets demonstrated an advance in phenology. Temperature was most frequently identified as the primary driver of phenological changes; however, in many studies it was the only climate variable considered. When precipitation was examined, it often played a key role but, in contrast with temperature, the direction of phenological shifts in response to precipitation variation was difficult to predict a priori. We discuss how phenological information can inform the adaptive capacity of species, their resilience, and constraints on autonomous adaptation. We also highlight serious weaknesses in past and current data collection and analyses at large regional scales (with very few studies in the tropics or from Africa and dramatic taxonomic biases. If accurate predictions regarding the general effects of climate change on the biology of organisms are to be made, data collection policies focussing on targeting data-deficient regions and taxa need to be financially

    This project was designed to demonstrate the potential of intrinsic bioremediation and phytoremediation in the Southern Sector of the A/M-Area at the Savannah River Site. A subsurface plume of trichloroethylene (TCE) and perchloroethylene (PCE) is present in the Lost Lake aquifer upgradient of the study site and is predicted to impact the area at some point in the future. The surface area along the Lost lake aquifer seep line where the plume is estimated to emerge was identified. Ten sites along the seep line were selected for biological, chemical, and contaminant treatability analyses. A survey was undertaken in this area to to quantify the microbial and plant population known to be capable of remediating TCE and PCE. The current groundwater quality upgradient and downgradient of the zone of influence was determined. No TCE or PCE was found in the soils or surface water from the area tested at this time. A TCE biodegradation treatability test was done on soil from the 10 selected locations. From an initial exposure of 25 ppm of TCE, eight of the samples biodegraded up to 99.9 percent of all the compound within 6 weeks. This biodegradation of TCE appears to be combination of aerobic and anaerobic microbial activity as intermediates that were detected in the treatability test include vinyl chloride (VC) and the dichloroethenes (DCE) 1,2-cis-dichloroethylene and 1,1-dichloroethylene. The TCE biological treatability studies were combines with microbiological and chemical analyses. The soils were found through immunological analysis with direct fluorescent antibodies (DFA) and microbiological analysis with direct fluorescent antibodies (DFA) and microbiological analysis to have a microbial population of methanotrophic bacteria that utilize the enzyme methane monooxygenase (MMO) and cometabolize TCE

    Aerial gamma ray surveys are an important tool for national security, scientific, and industrial interests in determining locations of both anthropogenic and natural sources of radioactivity. There is a relationship between radioactivity and geology and in the past this relationship has been used to predict geology from an aerial survey. The purpose of this project is to develop a method to predict the radiologic exposure rate of the geologic materials by creating a high resolution background model. The intention is for this method to be used in an emergency response scenario where the background radiation environment is unknown. Two study areas in Southern Nevada have been modeled using geologic data, images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), geochemical data, and pre-existing low resolution aerial surveys from the National Uranium Resource Evaluation (NURE) Survey. Using these data, geospatial areas that are homogenous in terms of K, U, and Th, referred to as background radiation units, are defined and the gamma ray exposure rate is predicted. The prediction is compared to data collected via detailed aerial survey by the Department of Energy's Remote Sensing Lab - Nellis, allowing for the refinement of the technique. By using geologic units to define radiation background units of exposed bedrock and ASTER visualizations to subdivide and define radiation background units within alluvium, successful models have been produced for Government Wash, north of Lake Mead, and for the western shore of Lake Mohave, east of Searchlight, NV.

  18. The Southern African Large Telescope project

    Buckley, David A. H.; Charles, Philip A.; Nordsieck, Kenneth H.; O'Donoghue, Darragh

    The recently completed Southern African Large Telescope (SALT) is a low cost, innovative, 10 m class optical telescope, which began limited scientific operations in August 2005, just 5 years after ground-breaking. This paper describes the design and construction of SALT, including the first-light instruments, SALTICAM and the Robert Stobie Spectrograph (RSS). A rigorous systems engineering approach has ensured that SALT was built to specification, on budget, close to the original schedule and using a relatively small project team. The design trade-offs, which include an active spherical primary mirror array and a fixed altitude telescope with a prime focus tracker, although restrictive in comparison to conventional telescopes, have resulted in an affordable 10 m class telescope for South Africa and its ten partners. Coupled with an initial set of two seeing-limited instruments that concentrate on the UV-visible region (320 - 900 nm) and featuring some niche observational capabilities, SALT will have an ability to conduct some unique science. This includes high time resolution studies, for which some initial results have already been obtained. Many of the versatile modes available with the RSS - which is currently being commissioned - are unique and provide unparallelled opportunities for imaging polarimetry and spectropolarimetry. Likewise, Multi-Object Spectroscopy (with slit masks) and imaging spectroscopy with the RSS, the latter using Fabry-Perot étalons and interference filters, will extend the multiplex advantage over resolutions from 300 to 9000 and fields of view of 2 to 8 arcminutes. Future instrumentation plans include an extremely stable, fibre-fed, high resolution échelle spectrograph and a near-IR (to between 1.5 to 1.7 μm) extension to the RSS. Future development possibilities include phasing the primary mirror and AO. Finally, extrapolations of the SALT/HET designs to ELT proportions remain viable and are surely more affordable than conventional

    The Southern African Large Telescope (SALT) is a low cost (19.7M), innovative, 10-m class optical telescope, which was inaugurated on 10 November 2005, just 5 years after ground-breaking. SALT and its first-light instruments are currently being commissioned, and full science operations are expected to begin later this year. This paper describes the design and construction of SALT, including the first-light instruments, SALTICAM and the Robert Stobie Spectrograph (RSS). A rigorous Systems Engineering approach was adopted to ensure that SALT was built to specification, on budget, close to the original schedule and using a relatively small project team. The design trade-offs, which include an active spherical primary mirror array in a fixed altitude telescope with a prime focus tracker, although restrictive in comparison to conventional telescopes, have resulted in an affordable and capable 10-m class telescope for South Africa and its ten partners. Coupled with an initial set of two seeing-limited instruments that concentrate on the UV-visible region (320 - 900nm) and featuring some unique observational capabilities, SALT will have an ability to conduct a wide range of science programs. These will include high time resolution studies, for which some initial results have already been obtained and are presented here. Many of the versatile modes available with the RSS will provide unparalleled opportunities for imaging polarimetry and spectropolarimetry. Likewise, Multi-Object Spectroscopy (using laser cut graphite slit masks) and imaging spectroscopy with the RSS, the latter using Fabry-Perot etalons and interference filters, will extend the multiplex advantage over resolutions from R = 300 to 9000 over fields of view of 2 to 8 arcminutes.

    Full Text Available The occurrence of tuberculosis (TB in prisons has been described as an alarming public health problem in many countries, especially in developing nations. The objective of this study was to conduct a survey among prisoners with TB respiratory symptoms in order to estimate the incidence of the disease, to analyze the drug susceptibility profile and genotype the isolates of Mycobacterium tuberculosis in the city of Charqueadas, southern of Brazil. The TB incidence was 55/1,900 inhabitants in the prison; this corresponds to an incidence of 3,789/100,000 inhabitants, with a prevalence of 72/1,900 (4,960/100,000 inhabitants. Drug susceptibility test was performed and, among the analyzed isolates, 85% were susceptible to all drugs tested and 15% were resistant to at least one drug, of which 89% were resistant only to isoniazid (INH or in combination with another drug. The genotype classification of spoligotyping analysis showed that 40% of the isolates belong to LAM family, 22% to T family, 17.5% to Haarlem family, 12.5% to U family and 3% to X family. The shared international spoligotypes most frequently found were 729 (27%, 50 (9.5%, 42 (8%, 53 (8% and 863 (8%. In conclusion, it was observed that TB in this specific population had been caused, mostly, by strains that have been transmitted in the last few years, as demonstrated by the large level of genotype clustering. In addition, it was found specific large clusters, which were not often found in the general population from the same period and in the same region.
