Middle to Upper Pleistocene and Holocene volcanic eruptions are difficult to date by Ar/Ar techniques when K-rich minerals such as sanidines are not present, as is the case in mafic and some intermediate rocks. However, these may contain phlogopite crystals suitable for Ar/Ar dating. Direct luminescence dating of volcanic feldspar is hampered by a poorly understood phenomenon of long-term signal instability called "anomalous fading" which, however, is apparently not present in quartz. To circumvent the fading problem involved in luminescence dating of volcanic rocks lacking quartz we sampled quartz-bearing crustal xenoliths from the Quaternary West and the East Eifel Volcanic Fields. Sufficient heating for zeroing of the acquired geological TL during eruption is sometimes but not always visible in the field and among others depends on the size of the xenolith. Quartz grains were extracted from the xenoliths by crushing, density separation and etching in HF or H2SiF6. The orange-red TL emission from quartz is known to have a very high saturation dose and was therefore employed using a new "lexsyg" luminescence reader equipped with a special detection unit for measuring this orange-red TL emission. Additionally, the existing data base of Ar/Ar dating results is increased by a series of new laser ablation step heating Ar/Ar dating results from samples extracted from identical volcanic eruptions. These can serve as verification of the luminescence dating attempts. Some first preliminary TL dating results in the range up to ca. 500 ka will be presented and discussed. Apparently, some TL ages from quartz extracts underestimate the Ar/Ar ages significantly. Possible explanations of age underestimates will be presented for discussion.

Clinical presentations of childhood leukaemia have been reported in case-only studies. The timing when these presentations start to occur prior to diagnosis is less clear. In this nested case-control study, 1,025 and 334 children with lymphoid and myeloid leukaemia, respectively, were matched (1:30) to population-based controls by sex, region and year of birth. An index date was assigned for each control when the matched case was diagnosed. Healthcare access records of cases and controls in the year before the index date were extracted. Children with lymphoid leukaemia started to visit doctors more often at least 2 months before leukaemia diagnosis (P < 0.05). Various presentations were recorded in these visits: rates of haematological presentations, musculoskeletal presentations, and injuries started to increase significantly at least 3 months before diagnosis; rates of respiratory, gastrointestinal and urinary tract presentations did not increase significantly until the last month. The findings for myeloid lymphoma were less clear, but children appeared to visit doctors more often at least 4 months before diagnosis, and the rate of haematological presentations also started to increase at least 4 months before leukaemia diagnosis. Although haematological presentations were most strongly associated with undiagnosed leukaemia (odds ratio > 290 in the last month), the majority (>96%) of children with haematological presentations did not have leukaemia if they had not been diagnosed in their first visit. We described a clinical picture in the year before leukaemia diagnosis. These findings revealed ongoing difficulties in early diagnosis of childhood leukaemia in healthcare settings. © 2016 Wiley Periodicals, Inc.

Synchronous colonic tumours of dual pathology are extremely rare. A review of the literature revealed that few cases have been reported to date. Because of their rarity and lack of specific symptoms, preoperative diagnosis is not easy and there is no protocol as yet for the ideal management of these cases. We present such a case which was treated by a combination of surgery and chemotherapy.

2010-09-01

Intraoral presentation of follicular lymphoma is rare, and only three cases in the palate have been reported to date. The present case report describes an uncommon case of follicular lymphoma affecting the palate. The clinical aspect was similar to salivary gland neoplasm, and an incisional biopsy was important to establish the correct diagnosis and consequently to plan the treatment. Also discussed is the differential diagnosis among follicular lymphoma, mucosa-associated lymphoid tissue lymphoma, and follicular lymphoid hyperplasia with regard to the histopathologic and immunohistochemical features.

Plutonium age dating reloaded

Sturm, Monika; Richter, Stephan; Aregbe, Yetunde; Wellum, Roger; Mayer, Klaus; Prohaska, Thomas

2014-05-01

Although the age determination of plutonium is and has been a pillar of nuclear forensic investigations for many years, additional research in the field of plutonium age dating is still needed and leads to new insights as the present work shows: Plutonium is commonly dated with the help of the 241Pu/241Am chronometer using gamma spectrometry; in fewer cases the 240Pu/236U chronometer has been used. The age dating results of the 239Pu/235U chronometer and the 238Pu/234U chronometer are scarcely applied in addition to the 240Pu/236U chronometer, although their results can be obtained simultaneously from the same mass spectrometric experiments as the age dating result of latter. The reliability of the result can be tested when the results of different chronometers are compared. The 242Pu/238U chronometer is normally not evaluated at all due to its sensitivity to contamination with natural uranium. This apparent 'weakness' that renders the age dating results of the 242Pu/238U chronometer almost useless for nuclear forensic investigations, however turns out to be an advantage looked at from another perspective: the 242Pu/238U chronometer can be utilized as an indicator for uranium contamination of plutonium samples and even help to identify the nature of this contamination. To illustrate this the age dating results of all four Pu/U clocks mentioned above are discussed for one plutonium sample (NBS 946) that shows no signs of uranium contamination and for three additional plutonium samples. In case the 242Pu/238U chronometer results in an older 'age' than the other Pu/U chronometers, contamination with either a small amount of enriched or with natural or depleted uranium is for example possible. If the age dating result of the 239Pu/235U chronometer is also influenced the nature of the contamination can be identified; enriched uranium is in this latter case a likely cause for the missmatch of the age dating results of the Pu/U chronometers.

Rao, K V L N; Beniwal, Manish; Vazhayil, Vikas; Somanna, Sampath; Yasha, T C

2017-12-01

Hemangiomas of the bone are benign, uncommon, slow-growing lesions accounting for <1.0% of all bony neoplasms. Intraosseous occipital hemangiomas are rare, and occipital hemangiomas presenting with features of raised intracranial tension are, with only 2 cases reported to date. In this case report, we describe the unique case of a 30-year-old male patient presenting with raised intracranial pressure due to venous obstruction at the torcula. The patient underwent excision of the lesion and became symptom free. Although these are benign lesions, they can have a varied clinical presentation. An understanding of the different clinical presentations and surgical nuances in excising such tumors can lead to early diagnosis and good patient outcome. Copyright © 2017 Elsevier Inc.

Choricarcinoma is a beta human chorionic gonadotrophin secreting neoplasm pertinent to uterus and pregnancy mostly. It occurs primarily in gonads but rarely in extragonadal sites. Primary hepatic choriocarcinoma is an extremely rare tumor. Most of the reported cases are seen in infants representing metastasis from an occult placental choriocarcinoma. Till date, only 7 cases of primary hepatic choriocarcinoma in adults have been reported in literature. We present a case of a 40-yearold male presenting as haemoperitoneum due to ruptured hepatic tumor. He underwent emergency left lateral segmentectomy. He died on 10th postoperative day. The surgical specimen and autopsy findings confirmed it to be primary hepatic choriocarcinoma. This is the first case report from Indian Subcontinent. A brief case report and review of literature is presented. PMID:24765472

2007-07-13

The diagnosis of crusted scabies is becoming more relevant due to the increase in number of immunocompromised patients. To date, more than 200 cases have been reported in the literature. However, crusted scabies seems to be under-diagnosed because of its unusual presentations. In this case series we present history, clinical manifestations, KOH smear, and histopathological findings of a series of four patients with crusted scabies. Scaly scalp was a prominent feature of the disease in all cases. Examination of and treatment of the scalp of patients with suspected crusted scabies should not be neglected. A KOH smear from the scalp offers a simple and reliable technique for diagnosis.

Physical and psychological dating violence in young men and women in Chile: Results from a 2005 survey of university students

2010-01-01

Numerous studies have documented high levels of intimate partner violence in Chile. Yet to date, research and prevention/ response programs have focused almost exclusively on cohabiting and married couples. This study presents a comparative analysis of dating violence prevalence in a sample of male and female college students in Chile and describes the contexts in which such violence takes place. Based on a survey of students enrolled in general education courses at a large, public university in Santiago during the Winter 2005 term (n= 484 women, 466 men), we find a high prevalence of physical and psychological dating violence, with patterns resembling those documented for other countries. We also find a high prevalence of having witnessed interparental violence during childhood. Our results present a compelling case for not continuing to neglect dating violence in Chile and other Latin-American countries: further research in this area, and the development and evaluation of prevention programs for youth, could go far in reducing the opportunity for aggression to become an established style of conflict resolution.

Age determination of subdural hematomas: survey among radiologists.

PubMed

Postema, F A M; Sieswerda-Hoogendoorn, Tessa; Majoie, C B L M; van Rijn, R R

2014-08-01

Abusive head trauma is a severe form of child abuse. One important diagnostic finding is the presence of a subdural hematoma. Age determination of subdural hematomas is important to relate radiological findings to the clinical history presented by the caregivers. In court this topic is relevant as dating subdural hematomas can lead to identification of a suspect. The aim of our study is to describe the current practice among radiologists in the Netherlands regarding the age determination of subdural hematomas in children. This is a cross-sectional study, describing the results of an online questionnaire regarding dating subdural hematomas among pediatric and neuro-radiologists in the Netherlands. The questionnaire consisted of sociodemographic questions, theoretical questions and eight pediatric cases in which the participants were asked to date subdural hematomas based on imaging findings. Fifty-one out of 172 radiologists (30 %) filled out the questionnaire. The percentage of participants that reported it was possible to date the subdural hematoma varied between 58 and 90 % for the eight different cases. In four of eight cases (50 %), the age of the subdural hematoma as known from clinical history fell within the range reported by the participants. None of the participants was "very certain" of their age determination. The results demonstrate that there is a considerable practice variation among Dutch radiologists regarding the age determination of subdural hematomas. This implicates that dating of subdural hematomas is not suitable to use in court, as no uniformity among experts exists.

Arabia Terra is a region of Mars where occurrence of past-water manifests at surface and subsurface. To date, several landforms associated with this activity were recognized and mapped, directly influencing the models of fluid circulation. In particular, within several craters such as Firsoff and an unnamed southern crater, putative mud volcanoes were described by several authors. In fact, numerous mounds (from 30 m of diameter in the case of monogenic cones, up to 3-400 m in the case of coalescing mounds) present an apical vent-like depression, resembling subaerial Azerbaijan mud volcanoes and gryphons. To this date, landform analysis through topographic position index and curvatures based on topography was never attempted. We hereby present a landform classification method suitable for mounds automatic mapping. Their resulting spatial distribution is then studied in terms of self-similar clustering.

Background Edema associated with quetiapine has been described in only one case report to date and represents a potentially serious adverse reaction. Methods We present a case series of three patients who developed bilateral leg edema following initiation of quetiapine. Results One of these patients had a recurrence of edema with subsequent rechallenge. Another patient developed quetiapine-induced edema following a prior episode of olanzapine-induced edema. All the cases present a compelling temporal relationship between the drug challenge and the adverse event. Conclusions Prompt recognition and intervention with discontinuation of the offending agent is important for this potentially serious, seemingly idiosyncratic, vascular complication. PMID:19439156

Effects of perpetrator identity on suicidality and nonsuicidal self-injury in sexually victimized female adolescents

2016-01-01

Purpose Child sexual abuse and sexual dating violence victimization are common problems that are known to have long-term negative consequences. This study aimed to compare the sociodemographic, abuse-related, and clinical features of female adolescents who were sexually abused by different perpetrators, and identify the factors associated with suicidality and nonsuicidal self-injury (NSSI) in these cases. Patients and methods Data of 254 sexually abused female adolescents between the ages of 12–18 years were evaluated. The cases were classified into three groups, namely “sexual dating violence”, “incest”, and “other child sexual abuse”, according to the identity of the perpetrator. The three groups were compared in terms of sociodemographic, abuse-related, and clinical features. Results Major depressive disorder was the most common psychiatric diagnosis, which was present in 44.9% of the cases. Among all victims, 25.6% had attempted suicide, 52.0% had suicidal ideation, and 23.6% had NSSI during the postabuse period. A logistic regression analysis revealed that attempted suicide was predicted by dating violence victimization (adjusted odds ratio [AOR] =3.053; 95% confidence interval [CI] =1.473, 6.330) and depression (AOR =2.238; 95% CI =1.226, 4.086). Dating violence victimization was also the strongest predictor of subsequent suicidal ideation (AOR =3.500; 95% CI =1.817, 6.741). In addition, revictimization was determined to be an important risk factor for both suicidal ideation (AOR =2.897; 95% CI =1.276, 6.574) and NSSI (AOR =3.847; 95% CI =1.899, 7.794). Conclusion Perpetrator identity and revictimization are associated with negative mental health outcomes in sexually victimized female adolescents. Increased risk of suicidality and NSSI should be borne in mind while assessing cases with dating violence and revictimization histories, in particular. PMID:27382291

2013-01-01

Background and Purpose Epidemiologic studies of intracerebral hemorrhage (ICH) have consistently demonstrated variation in incidence, location, age at presentation, and outcomes among non-Hispanic white, black, and Hispanic populations. We report here the design and methods for this large, prospective, multi-center case-control study of ICH. Methods The ERICH study is a multi-center, prospective case-control study of ICH. Cases are identified by hot-pursuit and enrolled using standard phenotype and risk factor information and include neuroimaging and blood sample collection. Controls are centrally identified by random digit dialing to match cases by age (+/−5 years), race, ethnicity, gender and metropolitan region. Results As of March 22, 2013, 1,655 cases of ICH had been recruited into the study which is 101.5% of the target for that date and 851 controls had been recruited which is 67.2% of the target for that date (1,267 controls) for a total of 2,506 subjects which is 86.5% of the target for that date (2,897 subjects). Of the 1,655 cases enrolled, 1,640 cases had the case interview entered into the database of which 628 (38%) were non-Hispanic black, 458 (28%) were non-Hispanic white and 554 (34%) were Hispanic. Of the 1,197 cases with imaging submitted, 876 (73.2%) had a 24 hour follow-up CT available In addition to CT imaging, 607 cases have had MRI evaluation. Conclusion The ERICH study is a large, case-control study of ICH with particular emphasis on recruitment of minority populations for the identification of genetic and epidemiologic risk factors for ICH and outcomes after ICH.

We consider whether the long term perturbation of radiocarbon dates, which is known to be approximately a sin function of period about 8000 years and amplitude of about 8% peak-to-peak, could have been caused in any major part by vulcanism. We conclude that this is not the case. On the contrary, present day volcanoes are a far less important source of inert CO{sub 2} (about 100 fold less) than is man's burning of fossil fuels which has caused the Suess dilution of about 2%.

Cannabinoid hyperemesis has recently been described in the literature. It is a syndrome characterized by severe nausea and hyperemesis in the setting of chronic marijuana abuse and, to date, has been described only in adults. We describe the syndrome in 2 pediatric patients, for whom extensive gastrointestinal workups failed to identify a clear cause and cessation of marijuana use resulted in the alleviation of their symptoms. As in most published adult cases, compulsive bathing was present in both of these cases.

Coupling of Uranium and Thorium Series Isotope Systematics for Age Determination of Late Pleistocene Zircons using LA-ICP-MS

NASA Astrophysics Data System (ADS)

Sakata, S.; Hirakawa, S.; Iwano, H.; Danhara, T.; Hirata, T.

2014-12-01

Zircon U-Th-Pb dating method is one of the most important tools for estimating the duration of magmatism by means of coupling of uranium, actinium and thorium decay series. Using U-Pb dating method, its reliability is principally guaranteed by the concordance between 238U-206Pb and 235U-207Pb ages. In case of dating Quaternary zircons, however, the initial disequilibrium effect on 230Th and 231Pa should be considered. On the other hands, 232Th-208Pb dating method can be a simple but powerful approach for investigating the age of crystallization because of negligible influence from initial disequilibrium effect. We have developed a new correction model for accurate U-Pb dating of the young zircon samples by taking into consideration of initial disequilibrium and a U-Pb vs Th-Pb concordia diagram for reliable age calibration was successfully established. Hence, the U-Th-Pb dating method can be applied to various zircons ranging from Hadean (4,600 Ma) to Quaternary (~50 ka) ages, and this suggests that further detailed information concerning the thermal history of the geological sequences can be made by the coupling of U-Th-Pb, fission track and Ar-Ar ages. In this presentation, we will show an example of U-Th-Pb dating for zircon samples from Sambe Volcano (3 to 100 ka), southwest Japan and the present dating technique using LA-ICP-MS.

Agricultural biotechnology is being rapidly adopted as evidenced by the acreage of genetically modified (GM) crops planted and tonnes of product (grain and fiber) harvested. Concurrent with this technological progress, is a growing concern that the worlds biological diversity is coming under increasing threat from human activities. As such, ecological risk assessment approaches are being developed for GM crop plants as international agreements regulating the transboundary movements of these products are being implemented. This paper reviews the ecological risk assessment approach that has been used to date to approve GM crops to date. The process has been case-by-case, using a comparative, science-based approach balancing the potential risks and benefits of the new technology versus those present with the currently accepted practices. The approach used to evaluate and approve these products is consistent with the conditions and requirements outlined in the Cartagena Protocol.

Shadows and darkness in the brain of a genius: Aspects of the neuropsychological literature about the final illness of Maurice Ravel (1875–1937)

PubMed Central

Cavallera, Guido M.; Giudici, Simonetta; Tommasi, Luca

2012-01-01

Summary In 1948 the famous French neurologist Théophile Alajouanine published the article “Aphasia and artistic realization”, a landmark in the field of research about aphasia, which discussed the case of the composer Maurice Ravel (1875–1937). Since then, many researchers have explored the final illness of the composer. In 2003 Medical Science Monitor published 2 articles about the case. In this article we intend to present works published on the Ravel case, to discuss them, and to suggest a general overview on the topic. Many hypotheses have been proposed by researchers, but complete diagnosis is still an enigma, since no post-mortem was made. The most up-to-date perspective seems to point to comorbidity of superimposed elements, which might date back to the composer’s fragile youth. PMID:23018361

Human Nipah encephalitis outbreaks have been identified almost yearly in Bangladesh since 2001. Though raw date palm sap consumption and person-to-person contact are recognized as major transmission pathways, alternative pathways of transmission are plausible and may not have been identified due to limited statistical power in each outbreak. We conducted a risk factor analysis using all 157 cases and 632 controls surveyed in previous investigations during 2004-2012 to identify exposures independently associated with Nipah, since date palm sap was first asked about as an exposure in 2004. To further explore possible rare exposures, we also conducted in-depth interviews with all cases, or proxies, since 2001 that reported no exposure to date palm sap or contact with another case. Cases were 4.9 (95% 3.2-7.7) times more likely to consume raw date palm sap and 7.3 (95% 4.0-13.4) times more likely to have contact with a Nipah case than controls. In-depth interviews revealed that 39/182 (21%) of Nipah cases reporting neither date palm sap consumption nor contact with another case were misclassified. Prevention efforts should be focused on interventions to interrupt transmission through date palm sap consumption and person-to-person contact. Furthermore, pooling outbreak investigation data is a good method for assessing rare exposures.

Adolescent muscle dysmorphia and family-based treatment: a case report.

PubMed

Murray, Stuart B; Griffiths, Scott

2015-04-01

A growing body of evidence suggests that the prevalence of male body dissatisfaction and muscle dysmorphia is rising. To date, however, there is no published evidence on the efficacy of treatments for muscle dysmorphia. We present the case of a 15-year-old boy who met full diagnostic criteria for muscle dysmorphia, whose symptoms were treated into remission with eating disorder-focused, family-based treatment. The age of this patient fell within the time period in which symptoms of muscle dysmorphia are most likely to develop and this case represents the first published case report of family-based treatment for muscle dysmorphia in this age group. Thus, this case report has important implications for clinicians considering treatment options for presentations of muscle dysmorphia when first presenting in adolescence. Implications for the development of treatment guidelines for muscle dysmorphia and for the diagnostic debate surrounding muscle dysmorphia are also discussed. © The Author(s) 2014.

2018-01-01

Autoerythrocyte sensitization syndrome (Gardner Diamond syndrome or GDS) is a rare syndrome characterized by painful and spontaneous purpura commonly affecting adult women, and is mostly associated with psychiatric illness. Diagnosis is mainly based on clinical presentation, exclusion of other simulating diseases, and psychiatric evaluation. Only few cases have been reported till date. We report five cases of spontaneous purpura with a normal investigation profile, except for iron deficiency anemia in 1 patient, of which three had associated underlying psychiatric illness. Autoerythrocyte sensitization test was positive in all our cases. Patients presenting with painful bruises without significant medical history such as underlying bleeding disorder or drug history or history of trauma should be considered for autoerythrocyte sensitization syndrome, and managed accordingly. The present study is a case series of patients with characteristic features of autoerythrocyte sensitization syndrome, considering the rarity of the reports on its clinical spectra. PMID:29644197

2015-01-01

Gastric volvulus is a rare post-pneumonectomy complication. Although it has been described previously, published cases are limited to an older patient population. We report the youngest case of postpneumonectomy gastric volvulus to date, occurring in an 18-year-old male with a history of inflammatory myofibroblastic pseudotumor who underwent left intrapericardial pneumonectomy, and presented 13 years later with chronic intermittent mesenteroaxial gastric volvulus. While postpneumonectomy gastric volvulus is a rare occurrence, it should remain in the differential diagnosis in postoperative thoracic surgical patients presenting with chest pain. PMID:26504742

Monocephalus diprosopus is a form of conjoined twinning characterized by a single body, one unusual head and two faces or a spectrum of duplication of the craniofacial structures. Such cases have been mainly described according to postmortem pathologic examination. This presented case is a 26-week-stillborn female fetus, with unusual facial appearance with four eyes, two mouths, two noses, two ears and a defective cranial vault. To our knowledge, a detailed computerized tomography (CT) examination of the aberrant facial and cranial bones of such a case has not been reported to date. In this reported case, we present an anencephalic monocephalus diprosopus "headed twin", and describe the CT findings with emphasis on the cranial bones.

2016-01-01

Emergency departments (EDs) serve a wide range of patients who present at risk of impending suicide and homicide. Two statewide surveillance systems were probabilistically linked to understand who utilizes EDs and then dies violently within 6 weeks. Each identified case was matched with four randomly selected controls on sex, race, date of birth, resident zip code, and date of ED visit vs. date of death. Matched-pair odds ratios were estimated by conditional logistic regression to assess differences between cases and controls on reported diagnoses and expected payment sources. Of 1,599 suicides and 569 homicides in the 3-year study period, 10.7% of decedents who died by suicide (mean = 13.6 days) and 8.3% who died by homicide (mean = 16.3 days) were seen in a state ED within 6 weeks prior to death. ED attendees who died by suicide were more likely to have a diagnosis of injury/ poisoning diagnosis or mental disorder and more likely to have Medicare. Those who died by homicide were more likely to have a diagnosis of injury/poisoning and less likely to have commercial insurance. It is essential for research to further explore risk factors for imminent suicide and homicide in ED patients who present for psychiatric conditions and general injuries.

Intraocular gnathostomiasis is a rare parasitic infection caused by the third-stage larvae of spiruroid nematode Gnanthostoma spp. seen mostly in tropical and subtropical regions. It is a food-borne zoonosis caused by ingestion of raw or undercooked freshwater fish, amphibians, reptiles, birds, and mammals, all of which are known to harbor advanced third-stage larvae of Gnanthostoma spp. To date, 74 cases of intraocular gnathostomiasis have been reported from 12 different countries. Only four countries have reported more than 10 cases each, and India shares the rare distinction of being one of them, with 14 cases. Surprisingly, not a single case of cutaneous gnanthostomiasis has ever been reported from India. We present one such case of intraocular gnathostomiasis in a 41-year-old male who presented with an actively motile worm attached to the iris, and we review the pertinent literature of all such cases reported from India.

Enterobius vermicularis infestation leading to Meckel's diverticulitis in an adolescent boy: An extremely rare presentation.

PubMed

Sharma, Manupriya; Kaul, Rashmi; Chander, Bal

2018-01-01

Enterobius vermicularis is an intestinal nematode commonly affecting children worldwide. Its transmission is by feco-oral route. Meckel's diverticulitis due to E. vermicularis infestation is an extremely rare presentation. An 11-year-old boy presented with acute abdomen. During surgery inflamed Meckel's diverticulum (M.D) was seen. Histopathology examination of specimen revealed E. vermicularis . Till date, only one case of E. vermicularis infestation of M.D is reported around five decades ago. This histopathological confirmation is extremely important as the required treatment (Mebendazole) of the infected case along with household contacts can prevent the spread of infection and may avoid surgery in known contacts.

2017-07-01

Radial nerve palsy is a rare but serious complication following elbow external fixation. Only 11 cases have been reported in the literature to date, but the incidence may be underreported. We present three new cases of this complication. We analyzed the three cases of radial palsy seen in our center following the application of an external fixator as treatment for complex elbow injuries. Mean patient age at surgery was 50 years. Two patients were female and one was male. In the three cases, the initial lesion was a posterior elbow dislocation, associated with a fracture of the radial shaft in one and a radial head fracture and coronoid fracture, respectively, in the other two. Due to persistent elbow instability, an external fixator was applied in all three cases. The fixator pins were introduced percutaneously in two cases and under direct vision in an open manner in the third case. Radial palsy was noted immediately postoperatively in all cases. It was permanent in two cases and temporary in the third. Radial nerve palsy after placement of an external elbow fixator was resolved in only 1 of our 3 cases and in 6 of the 11 cases in the literature to date. Although the event is rare, these alarming results highlight the need for recommendations to avoid this complication.

Dating human skeletal remains using 90Sr and 210Pb: case studies.

PubMed

Schrag, Bettina; Uldin, Tanya; Mangin, Patrice; Bochud, François; Froidevaux, Pascal

2014-01-01

In legal medicine, the post mortem interval (PMI) of interest covers the last 50 years. When only human skeletal remains are found, determining the PMI currently relies mostly on the experience of the forensic anthropologist, with few techniques available to help. Recently, several radiometric methods have been proposed to reveal PMI. For instance, (14)C and (90)Sr bomb pulse dating covers the last 60 years and give reliable PMI when teeth or bones are available. (232)Th series dating has also been proposed but requires a large amount of bones. In addition, (210)Pb dating is promising but is submitted to diagenesis and individual habits like smoking that must be handled carefully. Here we determine PMI on 29 cases of forensic interest using (90)Sr bomb pulse. In 12 cases, (210)Pb dating was added to narrow the PMI interval. In addition, anthropological investigations were carried out on 15 cases to confront anthropological expertise to the radiometric method. Results show that 10 of the 29 cases can be discarded as having no forensic interest (PMI>50 years) based only on the (90)Sr bomb pulse dating. For 10 other cases, the additional (210)Pb dating restricts the PMI uncertainty to a few years. In 15 cases, anthropological investigations corroborate the radiometric PMI. This study also shows that diagenesis and inter-individual difference in radionuclide uptake represent the main sources of uncertainty in the PMI determination using radiometric methods.

A solitary polypoid gastric metastasis 20 years after renal cell carcinoma: an event to be considered, and a brief review of the literature.

PubMed

Onorati, M; Petracco, G; Uboldi, P; Redaelli, D G; Romagnoli, S; Albertoni, M; Di Nuovo, F

2013-08-01

The incidence of gastric metastasis is 2.6%. Although all primary neoplasms can metastasize to the stomach, most originate from melanoma or breast and lung cancer. Their most common endoscopic appearance is a "volcano-like" polypoid mass covered by normal mucosa that may show a central ulceration. Renal cell carcinoma, clear cell type, is known to spread hematogenously, and isolated metastasis to the stomach is a rare event. In this report, we describe a gastric recurrence of RCC, clear-cell type, in a 80-year-old patient who had undergone nephrectomy 20 years before. We also performed a brief review of the literature to update the number of cases described to date. Metastatic involvement of the stomach should be suspected in any patient with a previous history of renal cell carcinoma, clear cell type, presenting with gastrointestinal symptoms, even if many years after nephrectomy. The peculiarity of our case is due to the very late presentation of the gastric metastasis. Only two cases of very late gastric metastases from RCC, clear cell type, have been described in the literature, to date.

ETHNOBOTANICAL SURVEY OF PHOENIX DACTYLIFERA L. POLLEN USED FOR THE TREATMENT OF INFERTILITY PROBLEMS IN ALGERIAN OASES

PubMed Central

Selmani, Cherifa; Chabane, Djamila; Bouguedoura, Nadia

2017-01-01

Background: The Phoenix dactylifera L. (date palm) is known for its traditional medicinal properties across the history of native population in Algerian Sahara. There is a large trend of consumption of date palm pollen preparations in many human infertility cases in our country. However, the validity has not been scientifically tested. There has been no direct scientific research on this application. This study was undertaken to identify cultivars with greater potential in the traditional medicine uses. To evaluate the effects of date palm pollen on some sexual behavioural parameters of male adult rats, we tested the role of pollen powder from Deglet Nour cultivar on some male reproductive parameters. Materials and Methods: An Ethnobotanical survey was conducted in 17 oases in southern Algeria to identify all cultivars with medicinal interest. Local people were interviewed with open questions. A questionnaire and personal interviews for data collection were designed to record important cultivars, parts used and preparations. To determine the active constituents of date palm pollen used in traditional medicine, a phytochemical screening was performed. The effects of oral administration of date palm pollen suspension on male adult rats were investigated on body and testicle weights, serum testosterone level. Results: 131 prominent cultivars were found within 12 cultivars containing various parts with medicinal effects. Some primary and secondary metabolites were detected by phytochemical screening. The pollen increased the weight of the body, testicles and enhanced the serum testosterone level of male rats treated. Conclusion: The present survey has provided the identification and recognition of date palm cultivars used in traditional Saharan medicine. Date palm pollen could improve sexual activities in male infertility cases and may be attempted to derive drugs. PMID:28480429

Pectin extraction from lemon by-product with acidified date juice: rheological properties and microstructure of pure and mixed pectin gels.

PubMed

Masmoudi, M; Besbes, S; Ben Thabet, I; Blecker, C; Attia, H

2010-04-01

The microstructure and the rheological properties of lemon-pectin mixtures were studied and compared to those of pure lemon (high methoxyl: HM) and date (low methoxyl: LM) pectins. Rheological properties were carried out in the presence of 30%, 45% and 60% sucrose, and increasing calcium concentrations (0-0.1%). The presence of date with lemon pectin led to a gel formation at 45% sucrose and in the presence of calcium, which was not the case for lemon pectin alone under the same conditions. It is suggested that lemon and date pectins interacted, leading to gel formations at different gelling temperatures, which were strongly dependent on degree of methylation. These results were confirmed by scanning electron microscopy, which revealed inhomogeneous gels where dense aggregated network and loose, open network areas were present. Addition of calcium to pectin mixture gels led to stronger and faster gel formation.

Vascular Ehlers-Danlos Syndrome (VEDS) is a rare autosomal dominant collagen vascular disorder. Different from other Ehler-Danlos Syndrome subtypes, VEDS has poor prognosis due to severe fragility of connective tissues and association with life-threatening vascular and gastrointestinal complications. Spontaneous splenic rupture is a rare but hazardous complication related to this syndrome. To date, only 2 cases have been reported in the literature. Here we present another case of this uncommon complication, occurring in a 54-year-old woman in clinical follow-up for VEDS who presented with sudden onset of abdominal pain and hypotension. © The Author(s) 2015.

The non-Langerhans cell histiocytosis (LCH) juvenile xanthogranulomatosis (JXG) is usually a benign disease limited to the skin. Only a few cases of systemic disease with at least two affected organs and lethal outcomes have been reported to date. Treatment is controversial and no standard protocol is available. We report the rare case of a 22-month-old boy presenting multiple erythematous brownish papules of the head, trunk and legs, which had developed starting from his 6th month of life. Additional symptoms were delayed psychomotor development, hydrocephalus and hepatosplenomegaly. Further diagnostics revealed a systemic JXG with involvement of the skin, central nervous system, liver and spleen. The patient did not respond to initial therapy with prednisone and vinblastine according to protocol III for LCH. However, further therapy with cytarabine and 2-chlorodeoxyadenosine followed by a consolidation phase with 2-chlorodeoxyadenosine alone was successful and the patient is in his 4th year of remission. We provide a comprehensive review of the reported cases of systemic JXG to date. © 2016 British Association of Dermatologists.

De Garengeot hernia was first described in 1731. It is rare type of hernia and there is no established mode of treatment for it to date. This work has been reported in line with the SCARE criteria (Agha et al., 2016). We present a case of a 72 years old male with a non-reducible right inguinal swelling diagnosed to be a femoral hernia with congested appendix within. There are less than 100 cases like this reported to date in the literature. Acute appendicitis within the femoral hernia is not a common problem to cross paths with. Prompt early treatment is recommended and directed at repairing the hernia after appendectomy. The method of treatment is controversial and not well established due to the scarcity of cases but open repair without mesh is the preferred approach. De Garengeot hernia is a rare hernia to encounter. Imaging modalities are a major tool in early diagnosis and early prompt surgery is crucial in preventing major complications that may lead to unnecessary morbidity and mortality. Copyright © 2018.

Interferon-γ receptor 1 (IFN-γR1) deficiency is one of the primary immunodeficiencies conferring Mendelian Susceptibility to Mycobacterial Disease (MSMD). Some cases of neoplasms have been recently reported in patients with MSMD, underlying the already known link between immunodeficiency and carcinogenesis. We report the first case of intracranial tumour, i.e. pineal germinoma, in a 11-year-old patient with complete IFN-γR1 deficiency. The first clinical presentation of the genetic immunodeficiency dates back to when the child was aged 2 y and 10 mo, when he presented a multi-focal osteomyelitis caused by Mycobacterium scrofulaceum. The diagnosis of IFN-γR1 deficiency (523delT/523delT in IFNGR1 gene) was subsequently made. The child responded to antibiotic therapy and remained in stable clinical condition until the age of 11 years, when he started complaining of frontal, chronic headache. MRI revealed a solid pineal region mass lesion measuring 20 × 29 × 36 mm. Histological findings revealed a diagnosis of pineal germinoma. The patient received chemotherapy followed by local whole ventricular irradiation with boost on pineal site, experiencing complete remission, and to date he is tumor-free at four years follow-up. Four other cases of tumors have been reported in patients affected by MSMD in our knowledge: a case of Kaposi sarcoma, a case of B-cell lymphoma, a case of cutaneous squamous cell carcinoma and a case of oesophageal squamous cell carcinoma. In conclusion, in patients with MSMD, not only the surveillance of infectious diseases, but also that of tumors is important.

Pitt-Hopkins syndrome (PTHS) is a rare, genetic disorder caused by a molecular variant of TCF4 which is involved in embryologic neuronal differentiation. PTHS is characterized by syndromic facies, psychomotor delay, and intellectual disability. Other associated features include early-onset myopia, seizures, constipation, and hyperventilation-apneic spells. Many also meet criteria for autism spectrum disorder. Here the authors present a series of 23 PTHS patients with molecularly confirmed TCF4 variants and describe 3 unique individuals. The first carries a small deletion but does not exhibit the typical facial features nor the typical pattern of developmental delay. The second exhibits typical facial features, but has attained more advanced motor and verbal skills than other reported cases to date. The third displays typical features of PTHS, however inherited a large chromosomal duplication involving TCF4 from his unaffected father with somatic mosaicism. To the authors' knowledge, this is the first chromosomal duplication case reported to date.

OSL surface exposure dating of wave-emplaced coastal boulders - Research concept and first results from the Rabat coast, Morocco

NASA Astrophysics Data System (ADS)

2017-04-01

Fields of wave-emplaced blocks and boulders represent impressive evidence of cyclone and tsunami flooding over Holocene time scales. Unfortunately, their use for coastal hazard assessment is in many cases impeded by the absence of appropriate dating approaches, which are needed to generate robust chronologies. The commonly applied AMS-14C, U/Th or ESR dating of coral-reef rocks and marine organisms attached to the clasts depends on a - mostly hypothetical - coincidence between the organisms' death and boulder displacement, and inferred event chronologies may be biased by the marine 14C-reservoir effect and reworked organisms. Here we discuss the potential of the recently developed optically stimulated luminescence (OSL) surface exposure dating technique to directly date the relocation process of wave-emplaced boulders. By measuring the depth-dependent resetting of luminescence signals in exposed rock surfaces and comparing it to the signal-depth profiles of known-age samples, OSL surface exposure dating may be capable to model direct depositional ages for boulder transport. Thereby, it promises to overcome the limitations of existing dating techniques, and to decipher complex transport histories of clasts that underwent multiple phases of exposure and burial. The concept and some first results of OSL surface exposure dating shall be presented for coastal boulders from the Rabat coast, Morocco, where the preconditions for successful dating are promising: (i) Several coastal boulders show clear indication of overturning during wave transport in the form of downward-facing bio-eroded surfaces; (ii) the boulders are composed of different types of sandstone that contain quartz and feldspar, the required dosimeters for OSL dating; (iii) all boulders are of Holocene age and, therefore, in the dating range of OSL surface exposure dating. The main challenges for a successful application are the intensive bio-erosion and weathering of some surfaces exposed after transport, and the need for method calibration using surfaces with similar lithology and known exposure ages. However, in the best case, OSL surface exposure dating will provide quantitative information about the frequency-magnitude relationship of extreme wave events at the Rabat coast, in particular determining whether severe tsunami-induced flooding can be expected (e.g. during the 1755 Lisbon tsunami and similar events), or if boulders were only moved during flooding by exceptional winter storms.

The author, based on up to date published dates, intends to present the classification and ethiopathogeny of the diaphragmatic hernias, except the aesophagic hiatus oms. This is an interesting chapter of the borderline surgery (abdominal and thorax). They are placed on the second position in frequency (after the hiatal hernias) in the diaphragmatic pathology; they are internal hernias, through congenital or obtained holes which allow to abdominal viscera to pass into thorax. They are--in the most cases, even elderly ones-congenital, result of the abnormalities in the embrionary growth of the diaphragm. A special place' is represented by the traumatic hernias.

The association of paracoccidioidomycosis with AIDS is apparently less frequent than expected. The authors present an unusual case of paracoccidioidomycosis in a 13-year-old female student which was later found to be the first opportunistic infection in the course of the patient's HIV-infection. The clinical presentation followed an accidental incised wound on the palmar region initially described as a 'sporotrichotic-chancre'. After good response under sulfamethoxazole-trimethoprin, the patient relapsed and presented an associated oral candidiasis. HIV-infection was documented and additional investigation showed CD4(+) T-cells=22/mm(3), CD8(+)=280 cell/mm(3) and viral load=4,043 log. This case report presents an uncommon dermatological-clinical picture in the youngest patient in which such association has been reported to date.

Primary cancer arising from multiple organs is a well known fact. Synchronous tumours have been most commonly associated with kidney cancer. Bladder, prostate, colorectal and lung cancer are the most common synchronous primaries with Renal Cell Carcinoma (RCC) identified till date. We found metachronous tumours of breast with RCC in literature search which included both metastatic tumours as well second primaries. Overall, 25 cases of metastatic breast tumours and eight cases of second primary in previously treated RCC have been reported in the literature. Here, we are reporting a case of synchronous presentation of carcinoma breast with RCC which is very rare because most of the multiple malignancies reported in the literature are metastatic tumours or metachronous breast malignancy with RCC.

This article reports the largest familial aggregation of Chiari malformation in a single family to date as reported in the literature. This study is a retrospective case series of a family of whom five individuals have a confirmed case of Chiari malformation and three additional individuals have Chiari signs and symptoms. This contribution further supports the implication of genetics in the transmission of Chiari malformation. The family reported in this study also has a significant incidence of Ehlers-Danlos. Three sisters, including a set of twins, presented with confirmed cases of Chiari malformation and four of the five children of the twin sisters presented with confirmed or suspected Chiari malformation. Of note, the non-twin sister has three children who are unaffected. This report provides further evidence for a shared loci between the Chiari malformation and Ehlers-Danlos.

Phyllodes tumour (PT) is a rare tumour of the female breast. The tumour clinically and radiologically mimics the features of a fibroadenoma. Ductal carcinoma in situ (DCIS) in the epithelial component of PT is a very rare finding. We present youngest ever case of a 23-year-old nulliparous woman with high-grade ductal carcinoma in situ arising within a benign phyllodes tumor. Macroscopically, it is a homogeneous tumour with solid components. Microscopically, it features typical leaf-like pattern with hypercellular stroma with high-grade ductal carcinoma in situ. To date, eight such rare cases of benign phyllodes tumour with ductal carcinoma in situ have been documented. We report the youngest case known in literature so far. As this is a very rare presentation, it poses several challenges in regard to both management and follow-up. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

Inverted follicular keratosis (IFK) is a rare benign tumor which usually appears as a firm papule on the face. The diagnosis is generally made by histopathology because the clinical appearance is difficult to differentiate from other lesions. Dermoscopic features of IFK have not been established to date. Herein we describe the dermoscopic findings of 4 cases of IFK. Radial peripheral hairpin vessels surrounded by a whitish halo arranged around a central white-yellowish amorphous area were observed in 3 cases, and glomerular vessels were present in the central area of one of them. The fourth case also presented a central white amorphous area but showed arborizing vessels. Reflectance confocal microscopy (available in 1 case) revealed a broadened honeycomb pattern, epidermal projections and hairpin and glomerular vessels. To our knowledge this is the first case series describing the dermoscopic features of inverted follicular keratosis and the first confocal microscopy description of this entity.

Fibrolamellar carcinoma (FLC) has been considered a distinct clinical entity vs. hepatocellular carcinoma, with respect to its epidemiology, etiology, and prognosis. We describe the unusual case of a 23-year-old female patient with FLC and ovarian (Krukenberg) and peritoneal metastases, clinically mimicking an ovarian carcinoma. Multiple recurrences occurred despite initial R0 resection and chemotherapy, requiring surgical treatment. The patient survived five years and died from generalized disease. The particularities of our case are discussed by comparison with the other two similar cases and other date from the literature. To our knowledge, the ovarian involvement encountered in our case is the third case published in literature, being explained by the superficial location of the liver tumor.

Cysts of the bile duct or choledochal cysts are rare diseases in our area. The aetiology is unknown, with the most accepted hypothesis being a pancreatobiliary maljunction anomaly. To analyse the clinical data, diagnosis and treatment of a number of patients with choledochal cyst, as well as presenting an update on this condition. A retrospective descriptive study was performed on paediatric patients diagnosed with choledochal cyst in the last 20 years in a tertiary hospital. A total of 4 choledochal cyst cases in childhood, predominantly female, are pre- sented. The most frequent reason for consultation was vomiting, and presenting with jaundice and choluria in all cases. Patients with choledochal cyst were classified as type I in 3 cases, and one case of type IVa. In all cases surgical treatment was performed; any patient had complications to date. Cysts of the bile ducts have a low prevalence. The treatment of choice is surgical, requiring close monitoring due to the risk of cholangiocarcinoma. Copyright © 2015 Sociedad Chilena de Pediatría.

Bhopal, R. S.; Diggle, P.; Rowlingson, B.

OBJECTIVES--To test the hypothesis that many non-outbreak cases of legionnaires' disease are not sporadic and to attempt to pinpoint cases clustering in space and time. DESIGN--Descriptive study of a case series, 1978-86. SETTING--15 health boards in Scotland. PATIENTS--203 probable cases of non-outbreak, non-travel, community acquired legionnaires' disease in patients resident in Scotland. MAIN MEASURES--Date of onset of disease and postcode and health board of residence of cases. RESULTS--Space-time clustering was present and numerous groups of cases were identified, all but two being newly recognised. Nine cases occurred during three months within two postcodes in Edinburgh, and an outbreak was probably missed. In several places cases occurred in one area over a prolonged period--for example, nine cases in postcode districts G11.5 and G12.8 in Glasgow during five years (estimated mean annual incidence of community acquired, non-outbreak, non-travel legionnaires' disease of 146 per million residents v 4.8 per million for Scotland). Statistical analysis showed that the space time clustering of cases in the Glasgow and Edinburgh areas was unusual (p = 0.036, p = 0.068 respectively). CONCLUSION--Future surveillance requires greater awareness that clusters can be overlooked; case searching whenever a case is identified; collection of complete information particularly of date of onset of the disease and address or postcode; ongoing analysis for space-time clustering; and an accurate yet workable definition of sporadic cases. Other researchers should re-examine their data on apparently sporadic infection. PMID:1586784

Central nervous system filariasis masquerading as a glioma: case report.

Filariasis, an endemic zoonosis in the Southeast Asia region, has been reported to affect various organs as well as the central nervous system (CNS). Inflammatory reactions mimicking those from neoplastic lesions clinically and radiologically have been reported in the breast and urinary bladder. To date, a CNS manifestation of filarial infestation has been reported in the form of meningoencephalitis. The authors here present an interesting case of a young man presenting in status epilepticus, which on radiological evaluation appeared to be a glioma. However, postoperative histopathological examination changed the provisional diagnosis to a filarial infection of the CNS mimicking a primary CNS neoplasm.

Gonadal dysgenesis, Turner syndrome with 46,XX,del(18p)3

The authors report a case of a female infant with gonadal dysgenesis, clinical features of Turner syndrome and a de novo del(18p). The factors controlling gonadal dysgenesis and Turner syndrome are unknown to date. The genes involved could be located not only on X chromosome but also on autosomes. The present case suggests that one of these genes is situated on the short arm of chromosome 18. We conclude that patients with del(18p) syndrome should be evaluated for gonadal dysgenesis.

After a differential diagnosis that includes erosive osteoarthritis and psoriatic arthritis, we believe rheumatoid arthritis (RA) to be the most probable cause. This example may therefore add to the evidence for an early date for the appearance of RA in Europe. Copyright © 2013 Elsevier Inc. All rights reserved.

SUMMARY Mucoepidermoid carcinoma is the most common malignant salivary gland tumour. However, short series or individual case reports have identified this tumour in the maxilla, mandible, breast tissue and thymus. Mucoepidermoid carcinoma originates from minor salivary glands, and it is therefore surprising that it is not more commonly seen in the tonsil. To date, we believe there has been only one previously reported case in the world literature of mucoepidermoid carcinoma occurring in the tonsil 1. We present a very rare case of mucoepidermoid carcinoma arising from within the structure of the palatine tonsil, rather from the adjacent pharyngeal wall, together with a short review of the literature.

Estimating a Markovian Epidemic Model Using Household Serial Interval Data from the Early Phase of an Epidemic

PubMed Central

Black, Andrew J.; Ross, Joshua V.

2013-01-01

The clinical serial interval of an infectious disease is the time between date of symptom onset in an index case and the date of symptom onset in one of its secondary cases. It is a quantity which is commonly collected during a pandemic and is of fundamental importance to public health policy and mathematical modelling. In this paper we present a novel method for calculating the serial interval distribution for a Markovian model of household transmission dynamics. This allows the use of Bayesian MCMC methods, with explicit evaluation of the likelihood, to fit to serial interval data and infer parameters of the underlying model. We use simulated and real data to verify the accuracy of our methodology and illustrate the importance of accounting for household size. The output of our approach can be used to produce posterior distributions of population level epidemic characteristics. PMID:24023679

A First Case of Human Trichuriasis from a Roman Lead Coffin in France.

Dufour, Benjamin; Segard, Maxence; Le Bailly, Matthieu

2016-10-01

A paleoparasitological study was carried out on 2 lead coffins recovered from the Roman site of Jaunay-Clan (near Poitiers, France). For the first time, this particular type of burial gave positive parasitological results, and eggs of the whipworm Trichuris trichiura were identified in 1 individual. In the present case, thanatomorphose associated with funerary practices may explain the scarcity of the recovered eggs. However, human whipworm has now been observed in 9 individuals dated to the Roman period. The very high frequency of Trichuris sp. eggs in Roman archaeological sites (up to 80%) suggests that fecal peril, hygiene, and waste management were problematic during this period. Finally, due to the fact that very few analyses have been conducted on human bodies dated to the Roman period, more analyses must be performed in the future to provide further information about diseases in the Roman world.

2017-07-01

In this paper, we review literature on antiforensics published between 2010 and 2016 and reveal the surprising lack of up-to-date research on this topic. This research aims to contribute to this knowledge gap by investigating different antiforensic techniques for devices running Windows 7, one of the most popular operating systems. An approach which allows for removal or obfuscation of most forensic evidence is then presented. Using the Trojan software DarkComet RAT as a case study, we demonstrate the utility of our approach and that a Trojan Horse infection may be a legitimate possibility, even if there is no evidence of an infection on a seized computer's hard drive. Up-to-date information regarding how forensic artifacts can be compromised will allow relevant stakeholders to make informed decisions when deciding the outcome of legal cases involving digital evidence. © 2017 American Academy of Forensic Sciences.

Severe pediculosis capitus: a case of "crusted lice" with autoeczematization.

PubMed

Connor, Cody J; Selby, John C; Wanat, Karolyn A

2016-03-16

Pediculosis humanus capitus infestations are common and classically present with intense pruritus of the scalp. Although many treatment options are available, lice are becoming more resistant to conventional therapies and severe clinical presentations are bound to become more prevalent. We present a case of treatment-resistant pediculosis capitus resulting in diffuse autoeczematization of the torso and extremities and severe crusting and scaling of the scalp, which we called "crusted lice." This eruption differs from the well-described id reaction known as "pediculid" and represents a more dramatic manifestation of rampant infestation. This paper provides an up-to-date review of treatment options available for pediculosis humanus capitus, including newer medications like the ones that eventually led to resolution of our patient's extreme infestation.

Improved arrival-date estimates of Arctic-breeding Dunlin (Calidris alpina arcticola)

Doll, Andrew C.; Lanctot, Richard B.; Stricker, Craig A.; Yezerinac, Stephen M.; Wunder, Michael B.

2015-01-01

The use of stable isotopes in animal ecology depends on accurate descriptions of isotope dynamics within individuals. The prevailing assumption that laboratory-derived isotopic parameters apply to free-living animals is largely untested. We used stable carbon isotopes (δ13C) in whole blood from migratory Dunlin (Calidris alpina arcticola) to estimate an in situ turnover rate and individual diet-switch dates. Our in situ results indicated that turnover rates were higher in free-living birds, in comparison to the results of an experimental study on captive Dunlin and estimates derived from a theoretical allometric model. Diet-switch dates from all 3 methods were then used to estimate arrival dates to the Arctic; arrival dates calculated with the in situ turnover rate were later than those with the other turnover-rate estimates, substantially so in some cases. These later arrival dates matched dates when local snow conditions would have allowed Dunlin to settle, and agreed with anticipated arrival dates of Dunlin tracked with light-level geolocators. Our study presents a novel method for accurately estimating arrival dates for individuals of migratory species in which return dates are difficult to document. This may be particularly appropriate for species in which extrinsic tracking devices cannot easily be employed because of cost, body size, or behavioral constraints, and in habitats that do not allow individuals to be detected easily upon first arrival. Thus, this isotopic method offers an exciting alternative approach to better understand how species may be altering their arrival dates in response to changing climatic conditions.

The first case study of 230Th/U and 14C dating of mid-valdai organic deposits

From the viewpoint of precision and reliability of radioisotopic dating, deposits whose quantitative age can be determined through several methods of geochronometry are of special interest. The mutually conforming finite 14C and 230Th/U dates of buried Neopleistocene organic deposits, taken from the Tolokonka section by the North Dvina River (100 km downstream from the city of Kotlas), have been obtained for the first time in Russia. The stratigraphical reference of these results to those obtained via the optically induced luminescence for upper and lower bedding layers has been established. The presented geochronometric data have allowed us to consider the age of oxbow lake organic deposits completely reliable and refer the time of their formation to the Tyrbei warming within the MIS-3. The applicability of the new version of the 230Th/U method for dating of interglacial and interstadial deposits, for the purpose of solving the Middle and Late Neopleistocene chronostratigraphy issues, is confirmed.

Pediatric constrictive asphyxia a rare form of child abuse: A report of two cases.

2018-04-01

We present two cases of infants who died under suspicious circumstances. After clinical and legal investigations, non-accidental constrictive asphyxia inflicted by one of the parents was established. The first case presents a to date not yet reported, unique mechanism of trauma. In order to stop his daughter from crying, the father admitted that he sometimes sat on his baby while she was lying on the bed. Occasionally increasing his force by pulling with his hands on the bottom of the bed. In the second case tight swaddling and encircling chest compression was the causative mechanism. In both cases the father was sentenced to imprisonment with mandate psychiatric care. Only two previous reports of this uncommon and relatively unknown cause of child abuse, called constrictive asphyxia, are known. In all reported cases static loading of the chest resulted in rib fractures and demise of the child. This rare abusive mechanism should be known to pediatric radiologists and pathologists.

Introduction Foetus-in-foetu is a very rare congenital abnormality where a malformed foetus is included within the body of another foetus. Less than 200 cases have been reported with over 80% occurring in the abdomen. Only three cases of cervical foetus in foetu have been reported. The present case of giant orocervical foetus-in-foetu appears to be an index case. Case presentation This is a report of an extremely rare orocervical foetus-in-foetu with grotesque oddity diagnosed on prenatal ultrasonography at 35 weeks gestational age in a 28-year-old, G2P1+0, Nigerian woman who was unsure of her last menstrual date or month. The included foetus had two eyes, cranium, nose, long bones and a spine. The mother's attempts at vaginal delivery rather than the elective Caesarean delivery she was offered resulted in obstructed labour and intrauterine foetal demise. Conclusion Giant cervical foetus-in-foetu is extremely rare. It could result in obstructed labour if vaginal delivery is attempted. PMID:19055795

[Use of Cone Beam Computed Tomography in endodontics: rational case selection criteria].

PubMed

Rosen, E; Tsesis, I

2016-01-01

To present rational case selection criteria for the use of CBCT (Cone Beam Computed Tomography) in endodontics. This article reviews the literature concerning the benefits of CBCT in endodontics, alongside its radiation risks, and present case selection criteria for referral of endodontic patients to CBCT. Up to date, the expected ultimate benefit of CBCT to the endodontic patient is yet uncertain, and the current literature is mainly restricted to its technical efficacy. In addition, the potential radiation risks of CBCT scan are stochastic in nature and uncertain, and are worrying especially in pediatric patients. Both the efficacy of CBCT in supporting the endodontic practitioner decision making and in affecting treatment outcomes, and its long term potential radiation risks are yet uncertain. Therefore, a cautious rational decision making is essential when a CBCT scan is considered in endodontics. Risk-benefit considerations are presented.

Fanconi's syndrome is a complex of multiple tubular dysfunctions of proximal tubular cells occurring alone or in association with a variety of inherited (primary) or acquired (secondary) disorders. It is characterized by aminoaciduria, normoglycaemic glycosuria, tubular proteinuria without hematuria, metabolic acidosis without anion gap and excessive urinary excretion of phosphorous, calcium, uric acid, bicarbonate, sodium, potassium, and magnesium. Whereas diabetes insipidus is a disease of collecting tubules and child mainly presents with dehydration and hypernatremia. Though all the cases published till date were secondary to drugs, myeloma, hematological disorders, etc., we are reporting the first case of idiopathic Fanconi's syndrome along with nephrogenic diabetes insipidus in a child who presented to us as resistant rickets. Medline search did not reveal any case of nephrogenic diabetes insipidus associated with idiopathic Fanconi syndrome. We hypothesized that the NDI may be due to of severe hypokalemia induced tubular dysfunction.

Large bowel and small bowel obstruction due to gallstones in the same patient

PubMed Central

Ranga, Natasha

2011-01-01

This is the case report of an 85-year-old woman who on two consecutive occasions presented with acute abdominal pain. The first presentation was large bowel obstruction. CT abdomen revealed this was due to a cholecystocolic fistula, allowing a large gallstone to pass and obstruct in the sigmoid colon. The second presentation was after laparotomy; the second CT abdomen revealed another gallstone causing small bowel obstruction. This case is interesting because cholelithiasis rarely leads to sigmoid colon obstruction (gallstone coleus)1 and gallstone ileus. Unfortunately, this patient had both. A gallstone causing obstruction in either the small or large bowel is rare, but occurrence of both in the same patient has not been reported to date. This case also shows how the elderly unwell surgical patient was mismanaged and she could have been spared surgery and irradiation if she was managed appropriately from the start. PMID:22696674

Solid organ transplantation is an accepted therapy for end-stage diseases of the kidneys, liver, heart, and lungs. Unfortunately, transplantation is associated with infectious complications. Here, we present a case report of Prototheca wickerhamii olecranon bursitis and review all of the cases in solid organ transplant (SOT) recipients published in the literature to date. In our patient, the infection resolved with surgical therapy and limited antifungal therapy, and no symptoms have recurred over 24 months of follow-up. A review of the literature suggests that 50% of SOT recipients with Prototheca infection present with disseminated infection, and the overall mortality is 75%. More studies are required to determine the optimal management of protothecosis in this population. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background . Date palm's pollen has been identified as a source of allergy; the rate of sensitization of this pollen is between 6 and 29%. Objective . To determine the prevalence of sensitization to date palm in Marrakesh and to identify the clinical profile. Patients and Methods . This study is based on a questionnaire and the prick test on 7 allergens, in population aged 5 years and above with clinical symptoms suggesting allergic diseases, from November 2012 to February 2013 in Marrakech. Results . We included 468 patients (women: 79.5%). The prick tests were considered interpretable in 467 cases. The prevalence of skin sensitization to pollen of date palm was 6.6%. The 31 cases of sensitization to date palm involved 7 men and 24 women with an average age of 37.5 years. Cutaneous monosensitization to date palm's pollen was observed in 2 cases. Asthma, rhinitis, and conjunctivitis were recorded, respectively, in 48.4%, 93.5%, and 67.7%. Conclusion . Skin sensitization to pollen of date palm does not seem unusual among allergic patients in Marrakech and is comparable to that found in Casablanca (7%), Barcelona (6.6%), and Cartagena (6.1%).

[Sinonasal hemangiopericytoma: review of four cases].

PubMed

Luna, B Azoulay; Chraibi, M; Abd, I Alsamad; Coste, A; Babin, E

2010-01-01

The aim of this paper is to discuss, through four cases, the characteristics of sinonasal hemangiopericytoma (SNHP) and its diagnostic difficulties. Description of four recent, histologically proven cases of SNHP. Bibliographic research was conducted using the following principal key word: "sinonasal hemangiopericytoma". The four patients complained of non-specific rhino-sinusal symptoms. In each case, physical examination revealed a voluminous unilateral polyploïd tumour of the nasal cavities, documented by CT Scan and MRI. Each patient underwent complete tumour resection by endoscopic sinus surgery. Histological and immunohistochemical examination confirmed SNHP diagnosis, although no specific marker was constantly observed. To date, none of the patients has presented with recurrence. SNHP is of poorly specific clinical and histological presentation. This tumour is difficult to distinguish from solitary fibrous tumour (SFT), with which it is often confused. SNHP is of good prognosis, however lifelong follow-up must be observed.

Introduction Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a rare benign vascular lesion with unknown etiopathogenesis and with definite features of imaging, histopathology, and immunohistochemistry. It was first described by Martel et al. in 2004, and to date, only 151 cases have been reported. Case Description We report a case of SANT of the spleen detected in a 66-year-old Caucasian, without comorbidities, presented to our department with epigastric pain. We, also, presented a review of the literature. Conclusions SANT is a benign incidentally vascular condition in the majority of cases. The wide age and gender distribution in our review is in accordance with that in previous studies in English literature. In our opinion, splenectomy is the choice treatment because it is at the same time diagnostic and therapeutic in a definitive way. PMID:29854543

2015-01-01

Lipomatous hemangiopericytomas are rare soft-tissue tumors that show areas of hemangiopericytoma like vascular pattern admixed with lipid containing cells. It is now considered a subtype of solitary fibrous tumor due to histopathological and immunohistochemical similarities. To date, only a few cases have been adequately reported in the medical literature. A case of lipomatous hemangiopericytoma in an 11-year-old female patient is presented and the clinical, histopathological and immunohistochemical features are discussed, along with a literature review. To the best of our knowledge, this is the first known case of a lipomatous hemangiopericytoma in a pediatric patient. Our case report further emphasizes that a number of studies should be evaluated to delineate hemangiopericytomas from solitary fibrous tumors. PMID:26097315

Modified-Fibonacci-Dual-Lucas method for earthquake prediction

NASA Astrophysics Data System (ADS)

Boucouvalas, A. C.; Gkasios, M.; Tselikas, N. T.; Drakatos, G.

2015-06-01

The FDL method makes use of Fibonacci, Dual and Lucas numbers and has shown considerable success in predicting earthquake events locally as well as globally. Predicting the location of the epicenter of an earthquake is one difficult challenge the other being the timing and magnitude. One technique for predicting the onset of earthquakes is the use of cycles, and the discovery of periodicity. Part of this category is the reported FDL method. The basis of the reported FDL method is the creation of FDL future dates based on the onset date of significant earthquakes. The assumption being that each occurred earthquake discontinuity can be thought of as a generating source of FDL time series The connection between past earthquakes and future earthquakes based on FDL numbers has also been reported with sample earthquakes since 1900. Using clustering methods it has been shown that significant earthquakes (<6.5R) can be predicted with very good accuracy window (+-1 day). In this contribution we present an improvement modification to the FDL method, the MFDL method, which performs better than the FDL. We use the FDL numbers to develop possible earthquakes dates but with the important difference that the starting seed date is a trigger planetary aspect prior to the earthquake. Typical planetary aspects are Moon conjunct Sun, Moon opposite Sun, Moon conjunct or opposite North or South Modes. In order to test improvement of the method we used all +8R earthquakes recorded since 1900, (86 earthquakes from USGS data). We have developed the FDL numbers for each of those seeds, and examined the earthquake hit rates (for a window of 3, i.e. +-1 day of target date) and for <6.5R. The successes are counted for each one of the 86 earthquake seeds and we compare the MFDL method with the FDL method. In every case we find improvement when the starting seed date is on the planetary trigger date prior to the earthquake. We observe no improvement only when a planetary trigger coincided with the earthquake date and in this case the FDL method coincides with the MFDL. Based on the MDFL method we present the prediction method capable of predicting global events or localized earthquakes and we will discuss the accuracy of the method in as far as the prediction and location parts of the method. We show example calendar style predictions for global events as well as for the Greek region using planetary alignment seeds.

Prototype and Evaluation of AutoHelp: A Case-based, Web-accessible Help Desk System for EOSDIS

NASA Technical Reports Server (NTRS)

Mitchell, Christine M.; Thurman, David A.

1999-01-01

AutoHelp is a case-based, Web-accessible help desk for users of the EOSDIS. Its uses a combination of advanced computer and Web technologies, knowledge-based systems tools, and cognitive engineering to offload the current, person-intensive, help desk facilities at the DAACs. As a case-based system, AutoHelp starts with an organized database of previous help requests (questions and answers) indexed by a hierarchical category structure that facilitates recognition by persons seeking assistance. As an initial proof-of-concept demonstration, a month of email help requests to the Goddard DAAC were analyzed and partially organized into help request cases. These cases were then categorized to create a preliminary case indexing system, or category structure. This category structure allows potential users to identify or recognize categories of questions, responses, and sample cases similar to their needs. Year one of this research project focused on the development of a technology demonstration. User assistance 'cases' are stored in an Oracle database in a combination of tables linking prototypical questions with responses and detailed examples from the email help requests analyzed to date. When a potential user accesses the AutoHelp system, a Web server provides a Java applet that displays the category structure of the help case base organized by the needs of previous users. When the user identifies or requests a particular type of assistance, the applet uses Java database connectivity (JDBC) software to access the database and extract the relevant cases. The demonstration will include an on-line presentation of how AutoHelp is currently structured. We will show how a user might request assistance via the Web interface and how the AutoHelp case base provides assistance. The presentation will describe the DAAC data collection, case definition, and organization to date, as well as the AutoHelp architecture. It will conclude with the year 2 proposal to more fully develop the case base, the user interface (including the category structure), interface with the current DAAC Help System, the development of tools to add new cases, and user testing and evaluation at (perhaps) the Goddard DAAC.

Graft thrombosis rates after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms vary widely in published series. When thrombosis does occur, it usually involves a single limb and occurs within 3 months of stent-graft insertion. If the entire endoprosthesis is thrombosed, treatment may be challenging because femoro-femoral crossover graft insertion is not an option and a greater volume of thrombus is present, thus making thrombolysis more difficult. We present two cases of delayed thrombosis after EVAR involving the entire stent-graft. These were successfully treated by a combined surgical and endovascular technique, and patency has been maintained in both cases tomore » date.« less

Nipah virus (NiV) is a paramyxovirus, and Pteropus spp. bats are the natural reservoir. From December 2010 through March 2014, hospital-based encephalitis surveillance in Bangladesh identified 18 clusters of NiV infection. The source of infection for case-patients in 3 clusters in 2 districts was unknown. A team of epidemiologists and anthropologists investigated these 3 clusters comprising 14 case-patients, 8 of whom died. Among the 14 case-patients, 8 drank fermented date palm sap (tari) regularly before their illness, and 6 provided care to a person infected with NiV. The process of preparing date palm trees for tari production was similar to the process of collecting date palm sap for fresh consumption. Bat excreta was reportedly found inside pots used to make tari. These findings suggest that drinking tari is a potential pathway of NiV transmission. Interventions that prevent bat access to date palm sap might prevent tari-associated NiV infection. PMID:26981928

Congenital tracheo-or-bronchobiliary fistula or congenital he-patopulmonary fistula is a rare malformation with high morbidity and mortality if the diagnosis is not made early. The tracheo-or-bronchobiliary fistula is a communication between the respiratory (trachea or bronchus) and biliary tract. To date, only 35 cases have been published worldwide. We report a case of a neonate with right pneumonia and bilious fluid in the endotracheal tube. Diagnosis was made using bronchoscopy with fluoroscopy. Videothoracoscopy was used to remove the bronchobiliary fistula. Subsequently, a left he-patectomy with Roux-en-Y biliary-digestive anastomosis was performed as bile ductus hypoplasia was present.

Accidental infection with animal filarial worms in humans is a dilemma for clinicians and parasitologists throughout the world. To date a variety of such rare parasitoses have been reported mostly in tropics and subtropics. Human dirofilariasis is among those unusual zoonotic infections that occasionally have been observed in the eye and in subcutaneous areas exhibiting with nodule formation. Filarial worms are transmitted to humans through invertebrate biological vectors such as certain species of mosquitoes. The present report describes a peculiar case of ocular dirofilariasis in a 49-year-old man resident in Iran. PMID:22347257

Robison, Steve G; Liko, Juventila

2017-04-01

To assess whether, during a 2012 pertussis outbreak, unvaccinated and poorly vaccinated cases occurred earlier on a community level. Pediatric pertussis among children 2 months to 10 years of age in the Oregon Sentinel Surveillance region during an epidemic starting at the beginning of 2012 were stratified by immunization status, age, zip code, and calendar date of disease onset. Differences in median onset as days between fully or mostly vaccinated, poorly vaccinated, and unvaccinated cases were examined overall and within local zip code areas. Disease clusters also were examined using SatScan analysis. Overall, 351 pertussis cases occurred among children aged 2 months to 10 years of age residing in 72 distinct zipcodes. Among unvaccinated or poorly vaccinated cases, their median date of onset was at calendar day 117 (April 26, 2012), whereas for those who were fully or mostly vaccinated the median date of onset was 41 days later, at day 158 (June 6, 2012). Within each local zip code area, the unvaccinated cases were 3.2 times more likely than vaccinated cases to have earlier median dates of onset (95% CI 2.9-3.6). In this outbreak, pertussis cases among unvaccinated children represented an earlier spread of disease across local areas. Controlling outbreaks may require attention to the composition and location of the unvaccinated. Copyright © 2016 Elsevier Inc. All rights reserved.

SUMMARY Drinking raw date palm sap is the primary route of Nipah virus (NiV) transmission from bats to people in Bangladesh; subsequent person-to-person transmission is common. During December 2010 to March 2011, we investigated NiV epidemiology by interviewing cases using structured questionnaires, in-depth interviews, and group discussions to collect clinical and exposure histories. We conducted a case-control study to identify risk factors for transmission. We identified 43 cases; 23 were laboratory-confirmed and 20 probable. Thirty-eight (88%) cases died. Drinking raw date palm sap and contact with an infected person were major risk factors; one healthcare worker was infected and for another case transmission apparently occurred through contact with a corpse. In absence of these risk factors, apparent routes of transmission included drinking fermented date palm sap. For the first time, a case was detected in eastern Bangladesh. Identification of new epidemiological characteristics emphasizes the importance of continued NiV surveillance and case investigation. PMID:26122675

Simultaneous Median and Ulnar Compression Neuropathy Secondary to a Giant Palmar Lipoma: A Case Report and Review of the Literature

PubMed Central

Unal, Melih; Demirayak, Engin; Acar, Baver

2018-01-01

Lipomas are benign tumors that rarely settle in the hand. They usually present with mass, pain, and nerve compression symptoms. Although isolated median or ulnar nerve compression neuropathy secondary to a lipoma of the hand has been widely reported, simultaneous median and ulnar nerve compression neuropathy are exceedingly rare and there are only three reported cases in the current literature to date. Herein, a case of a 50-year-old woman with a giant palmar lipoma that caused median and ulnar compression neuropathy is presented. The removal of the tumor resulted in the complete recovery of the patient’s symptoms. A deep-seated palmar lipoma should be kept in mind in patients with unilateral compression neuropathy symptoms with a palmar mass. PMID:29666776

2017-06-01

Thyroglossal duct cysts followed by branchial cleft anomalies are the most common congenital neck masses encountered in practice, second branchial cleft cysts and sinuses are the most common type (LaRiviere and Waldhausen in Surg Clin North Am 92(3):583-597, 2012). Although both abnormalities are common individually, but rarely seen associated in same patient as described in our case. Congenitalcervical anomalies are important to consider in the differential of head and neck masses in children and adults. These lesions can present as palpable cystic masses, infected masses, draining sinuses, or fistulae. Thyroglossal duct cysts are most common, followed by branchial cleft anomalies. A synchronous presentation of both type of cyst and fistula in a same child patient is very rare with no such cases reported in literature till date.

Growth hormone deficiency and diabetes insipidus as a complication of endoscopic third ventriculostomy.

PubMed

Tafuri, Kimberly S; Wilson, Thomas A

2012-12-01

Endoscopic third ventriculostomy (ETV) has become the procedure of choice for the treatment of obstructive hydrocephalus in children and adults. Endocrinological complications of ETV in children are rare. Diabetes insipidus (DI) is the most common and accounts for only 0.5% of complications from ETV. The majority of documented cases are transient. To date, there are no documented cases of multiple pituitary hormone deficiencies. We present here a 6-year-old girl with growth hormone deficiency and permanent DI which developed as a complication of ETV. This patient is unique in both demonstrating multiple pituitary hormone deficiencies and the classical triphasic response of DI after ETV. We postulate that these complications were caused by compression of the pituitary stalk and hypothalamic injury during the procedure. We compare our case presentation to experimental studies conducted in rats.

Coralline hydroxyapatite bone graft substitutes.

Elsinger, E C; Leal, L

1996-01-01

The authors present a review of the various bone grafts currently available with special attention to coral bone grafts. Several of the benefits of coralline hydroxyapatite bone graft substitutes, such as safety and biocompatibility, will be addressed in this article, part of an ongoing investigation of coral bone grafts used in triple arthrodesis procedures. To date, eight cases have been performed. In seven cases, granular chips were employed to pack the subtalar joint. The final case, presented in this article, represents a 26-year-old male who, 2 years previously, sustained a calcaneal fracture with resultant shortening along the lateral column. A coralline hydroxyapatite block was used at the calcaneocuboid joint to achieve distraction. Clinically, the patient is progressing well at 10 months postoperatively. Radiographically, one can still clearly appreciate the margins of the bone graft at 5 months.

A case study of anorexia nervosa driven by religious sacrifice.

PubMed

Davis, Amelia A; Nguyen, Mathew

2014-01-01

Anorexia nervosa (AN) is considered a relatively "modern" disorder; however, a number of scholarly works have cited examples of voluntary self-starvation dating back to several centuries. In particular, there are many examples of female starvation for religious reasons during the medieval period, with many being elevated to sainthood. We present a case of an elderly woman with AN who began restricting her diet when she was 13-years old while studying to be a nun at a Catholic convent. She reports that, during the development of her disease, she had no mirrors and, rather than restricting her diet to be thin or attractive, she restricted her diet to be closer to God in hopes of becoming a Saint. This unique case presents an opportunity to deepen our understanding of AN and the cultural context that affects its development.

2018-01-01

Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a rare benign vascular lesion with unknown etiopathogenesis and with definite features of imaging, histopathology, and immunohistochemistry. It was first described by Martel et al. in 2004, and to date, only 151 cases have been reported. We report a case of SANT of the spleen detected in a 66-year-old Caucasian, without comorbidities, presented to our department with epigastric pain. We, also, presented a review of the literature. SANT is a benign incidentally vascular condition in the majority of cases. The wide age and gender distribution in our review is in accordance with that in previous studies in English literature. In our opinion, splenectomy is the choice treatment because it is at the same time diagnostic and therapeutic in a definitive way.

2012-01-01

We investigated a cluster of patients with encephalitis in the Manikgonj and Rajbari Districts of Bangladesh in February 2008 to determine the etiology and risk factors for disease. We classified persons as confirmed Nipah cases by the presence of immunoglobulin M antibodies against Nipah virus (NiV), or by the presence of NiV RNA or by isolation of NiV from cerebrospinal fluid or throat swabs who had onset of symptoms between February 6 and March 10, 2008. We classified persons as probable cases if they reported fever with convulsions or altered mental status, who resided in the outbreak areas during that period, and who died before serum samples were collected. For the case-control study, we compared both confirmed and probable Nipah case-patients to controls, who were free from illness during the reference period. We used motion-sensor-infrared cameras to observe bat's contact of date palm sap. We identified four confirmed and six probable case-patients, nine (90%) of whom died. The median age of the cases was 10 years; eight were males. The outbreak occurred simultaneously in two communities that were 44 km apart and separated by a river. Drinking raw date palm sap 2-12 days before illness onset was the only risk factor most strongly associated with the illness (adjusted odds ratio 25, 95% confidence intervals 3.3-∞, p<0.001). Case-patients reported no history of physical contact with bats, though community members often reported seeing bats. Infrared camera photographs showed that Pteropus bats frequently visited date palm trees in those communities where sap was collected for human consumption. This is the second Nipah outbreak in Bangladesh where date palm sap has been implicated as the vehicle of transmission. Fresh date palm sap should not be drunk, unless effective steps have been taken to prevent bat access to the sap during collection.

Human plague--four states, 2006.

PubMed

2006-09-01

Plague is a zoonotic disease caused by the bacterium Yersinia pestis. In 2006, a total of 13 human plague cases have been reported among residents of four states: New Mexico (seven cases), Colorado (three cases), California (two cases), and Texas (one case). This is the largest number of cases reported in a single year in the United States since 1994. Dates of illness onset ranged from February 16 to August 14; two (15%) cases were fatal. The median age of patients was 43 years (range: 13-79 years); eight (62%) patients were female. Five (38%) patients had primary septicemic plague, and the remaining eight (62%) had bubonic plague. Two (15%) patients developed secondary plague pneumonia, leading to administration of antibiotic prophylaxis to their health-care providers. This report summarizes six of the 13 cases, highlighting the severity and diverse clinical presentations of plague and underscoring the need for prompt diagnosis and treatment when plague is suspected.

Sharing Rare Attitudes Attracts.

Alves, Hans

2018-04-01

People like others who share their attitudes. Online dating platforms as well as other social media platforms regularly rely on the social bonding power of their users' shared attitudes. However, little is known about moderating variables. In the present work, I argue that sharing rare compared with sharing common attitudes should evoke stronger interpersonal attraction among people. In five studies, I tested this prediction for the case of shared interests from different domains. I found converging evidence that people's rare compared with their common interests are especially potent to elicit interpersonal attraction. I discuss the current framework's theoretical implications for impression formation and impression management as well as its practical implications for improving online dating services.

The LDEF deintegration team and several experimenters noted severe fastener damage and hardware removal difficulties during post-flight activities. The System SIG has investigated all reported instances, and in all cases examined to date, the difficulties were attributed to galling during installation or post-flight removal. To date, no evidence of coldwelding was found. Correct selection of materials and lubricants as well as proper mechanical procedures is essential to ensure successful on-orbit or post-flight installation and removal of hardware.

Buchholz, B A

Radiocarbon dating can be used to determine the age of objects that contain components that were once alive. In the case of human remains, a radiocarbon date can distinguish between a crime scene and an archeological site. Documents, museum artifacts and art objects can be dated to determine if their age is correct for the historical context. A radiocarbon date does not confirm authenticity, but it can help identify a forgery.

Dedifferentiated liposarcoma (DDLS) has a relatively poor prognosis, however this neoplasm rarely occurs in the head and neck. To date, no definite protocol has been established for the diagnosis and treatment of head and neck DDLS. The present study reports the case of a 69-year-old male patient with DDLS of the oral floor. To the best of our knowledge, this is the first documented case of oral floor DDLS. In addition, this is the first reported case with the development of a second primary malignancy following the treatment of head and neck DDLS. A literature review of 50 cases of head and neck DDLS revealed that preoperative biopsy is not reliable for the diagnosis of these tumors and an accurate pathological diagnosis with total resection is preferred.

2001-01-01

The nasogastric tube syndrome is a potentially life-threatening complication of an indwelling nasogastric (NG) tube. The syndrome is thought to result from ulceration and infection of the posterior cricoid region with subsequent dysfunction of vocal cord abduction. This dysfunction may present as complete loss of vocal cord abduction manifested as serious airway compromise. Reports of this syndrome are infrequent, with only 29 cases published to date. Two additional cases of nasogastric tube syndrome diagnosed at the University of Iowa Hospitals and Clinics over a 2-year period are presented. A search of MEDLINE (1966 through February 1999), including review of those articles' references identified seven previous publications, including 29 case reports. These 29 cases are reviewed and the findings summarized. Twenty-nine cases of NG tube syndrome are identified, with 16 of these occurring in the preantibiotic period. Including the two cases presented here, 15 contemporary patients are examined. Among these 15 cases, 10 required tracheostomy, on average 8.5 days after NG tube placement. Although the fully manifested syndrome presents quite dramatically, we suspect that a clinical spectrum of severity exists with less severe cases going unrecognized. Consistent with previous reports, we found that direct visualization of the postcricoid region is required to rule out the diagnosis and recommend such action be taken whenever the diagnosis is suspected. Treatment should include establishment of a safe airway, removal of the tube whenever possible, antibiotic therapy, and antireflux therapy.

Plasma oxidation was used to obtain radiocarbon dates on six different materials from a naturally mummified baby bundle from the Lower Pecos River region of southwest Texas. This bundle was selected because it was thought to represent a single event and would illustrate the accuracy and precision of the plasma oxidation method. Five of the materials were clearly components of the original bundle with 13 dates combined to yield a weighted average of 2135 {+-} 11 B.P. Six dates from a wooden stick of Desert Ash averaged 939 {+-} 14 B.P., indicating that this artifact was not part of themore » original burial. Plasma oxidation is shown to be a virtually non-destructive alternative to combustion. Because only sub-milligram amounts of material are removed from an artifact over its exposed surface, no visible change in fragile materials has been observed, even under magnification. The method is best applied when natural organic contamination is unlikely and serious consideration of this issue is needed in all cases. If organic contamination is present, it will have to be removed before plasma oxidation to obtain accurate radiocarbon dates.« less

A 90-year-old man with factious disorder: Separating fact from fiction.

PubMed

Amladi, Anjani K; DePry, Dwayne R

2018-07-01

Objective Factitious disorders are known to exist in the medical community but are not commonly diagnosed in clinical practice. The majority of the literature on factitious disorder comes from case reports or case series. This particular case is unusual because it describes a patient who initially presented with purely physical complaints, but over time, the symptoms transitioned into predominantly psychiatric concerns. This case describes the patient's unique presentation and is followed by a discussion of the management of factitious disorder. Methods The patient was seen during the course of an inpatient psychiatric hospitalization. Electronic chart review was conducted, and information from each prior hospitalization was gathered between the dates of first initial documented presentation available in the electronic record in 1995 to most recent hospitalization in 2017. Results The patient still continues to present to the emergency department. Upon each presentation, staff work to objectively assess his complaints to be sure that there is no true underlying medical emergency. There is also a focus on providing non-judgmental, supportive, and compassionate care. Conclusion This case highlights the importance of corroborating objective findings with the patient's subjective reports gathered during a history and physical, and to recognize that patients with this disorder can present to any specialty. Thus, the collaboration between specialties is critical in the care of these patients to minimize unnecessary, costly, and sometimes dangerous interventions.

Heterozygote to homozygote related living donor liver transplantation in maple syrup urine disease: a case report.

Liver transplantation is an accepted treatment modality in the management of MSUD. To our knowledge, ours is only the second successful case to date of a patient with MSUD receiving an allograft from an RLD who is a heterozygous carrier for the disease. In view of the worldwide shortage of available organs for transplantation, heterozygote to homozygote transplantation in the setting of MSUD may provide a viable alternative for those awaiting transplantation. We report on the case of a two-yr-old infant with MSUD, who received a left lateral segment (segments II and III) liver transplant from his mother, a heterozygote carrier of one of the three abnormal genes implicated in MSUD. Post-operative BCAA levels normalized in our patient and remained so on an unrestricted protein diet and during times of physiological stress. To date, this is only the second case of a successful RLD liver transplant in a child with MSUD. Preliminary results indicate that RLD liver transplants are at least equivalent to deceased donor liver transplants in the treatment of MSUD, although longer term follow-up is required. Heterozygote to homozygote RLD transplant in patients with MSUD presents a new pool of potential liver donors. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Tuberculous Otitis Media Leading to Sequentialib Bilateral Facial Nerve Paralysis

Gupta, Nitin; Dass, Arjun; Goel, Neha; Tiwari, Sandeep

2015-01-01

Introduction: Tuberculous otitis media (TOM) is an uncommon, insidious, and frequently misdiagnosed form of tuberculosis (TB). In particular, TOM is usually secondary to direct transmission from adjacent organs, while the primary form has been rarely reported. The main aim of treatment is to start the patient on an antitubercular regime and early surgical intervention to decompress the facial nerve if involved. Case Report: The case report of a twenty year-old male with bilateral tuberculous otitis media, who presented himself with fever followed by sequential bilateral facial nerve paralysis, bilateral profound hearing loss, and abdominal tuberculosis leading to intestinal perforation, is presented. To the best available knowledge and after researching literature, no such case depicting the extensive otological complications of tuberculosis has been reported till date. Conclusion: Tuberculosis of the ear is a rare entity and in most cases the clinical features resemble that of chronic otitis media. The diagnosis is often delayed due to varied clinical presentations and this can lead to irreversible complications. Early diagnosis is essential for prompt administration of antitubercular therapy and to prevent complications. PMID:26082906

AG 85, a major secretion protein of Mycobacterium tuberculosis, can be identified in ancient bone.

Schmidt-Schultz, Tyede H; Schultz, Michael

2015-06-01

For the confirmation of Ag 85 in ancient and recent ECM of native macerated human bone, five cases were investigated. In three individuals, highly positive results for Ag 85 were identified in Western blot: 1) a male from Arzhan, South Siberia, dating from the 7th century BC, 2) a male from Kirchberg in Hesse, Germany, dating from the 10th - 12th century AD and 3) a recent female with a proven diagnosis of TB. As a negative control, a recent male is presented who did not suffer from TB. In another recent male, Ag 85 could be identified only very weakly. From cases in the literature it is well-known that highly positive results for Ag 85 indicate active TB, however, weakly positive results indicate a silent initial infection with Mtb. Thus, apparently, also in ancient individuals, it might well be possible to differentiate between diseased persons and disease carriers using paleoproteomic techniques. Copyright © 2015 Elsevier Ltd.

Squamous cell carcinoma (SCC) of the breast is an extremely rare form of cancer, accounting for approximately 0.04% of all malignant breast tumors. To date, only a limited number of cases of SCC of the breast have been reported, and most of them presented like the usual breast carcinomas. A 39-year-old woman presented with a large breast abscess and signs of sepsis. After surgical debridement of the lesion, histopathological examination of the abscess capsule revealed the presence of SCC of the breast. The definitive treatment for the tumor consisted of modified radical mastectomy with resection of the residual lesion in the right breast. This unusual case illustrates how an apparently benign disorder such as a breast abscess might be related to a clinically occult malignancy. A review of the literature on SCC of the breast is presented.

The aim of this study was to estimate the effect of cervical screening in the prevention of invasive cervical cancer among age groups, using a population-based case-control study in the province of Ontario, Canada. Exposure was defined as cervical cytology history greater than 3 months before the diagnosis date of cervical cancer (index date). Cases were women who were diagnosed with cervical cancer between January 1, 1998, and December 31, 2008. Controls were women without a diagnosis of cervical cancer on, or before, December 31, 2008. Two controls were matched to each case on year of birth and income quintile, as of the index date. Conditional logistic regression was used to estimate the odds ratio for having been screened among those with cervical cancer. Cervical cancer screening performed between 3 and 36 months before the index date was protective against invasive cervical cancer in women aged 40 through 69 years. In women younger than 40 years, cervical cancer screening performed 3 to 36 months before the index date was not protective. Cervical screening is associated with a reduced risk for invasive cervical cancer among women older than 40 years. Cervical cancer resources should be focused on maximizing the risk reduction.

Zircon is probably the most important mineral used in the dating formation of high-pressure (HP) and ultrahigh-pressure (UHP) metamorphic rocks. The origin of zircon, i.e., magmatic or metamorphic, is commonly assessed by its external morphology, internal structure, mineral inclusions, Th/U ratios and trace element composition. In this study, we present an unusual case of metamorphic zircon from the Qiangtang eclogite, north-central Tibet. The zircon grains contain numerous eclogite-facies mineral inclusions, including omphacite, phengite, garnet and rutile; hence, they are clearly of metamorphic origin. However, they display features similar to common magmatic zircon, including euhedral crystal habit, high Th/U ratios and enriched heavy rare earth elements pattern. We suggest that these zircon grains formed from a different reservoir from that for garnet where no trace elements was present and trace element equilibrium between zircon and garnet was achieved. U-Pb dating of zircon gave an age of 232-237 Ma for the eclogite, and that of rutile yielded a slightly younger age of ca. 217 Ma. These ages are consistent with the reported Lu-Hf mineral isochron and phengite Ar-Ar ages. The zircon U-Pb and mineral Lu-Hf isochron ages are interpreted as the time of the peak eclogite-facies metamorphism, whereas the rutile U-Pb and phengite Ar-Ar ages represent the time of exhumation to the middle crust. Thus, the distinction between metamorphic and magmatic zircons cannot be made using only Th/U ratios and heavy REE compositions for HP-UHP metamorphic rocks of oceanic derivation.

Leiomyoma is a benign tumor of the smooth muscle that rarely occurs in the mouth as an intraosseous lesion. The purposes of this paper are to: (1) present a case of an intraosseous solid leiomyoma of the mandible in a 13-year-old child, who presented with a well-defined unilocular radiolucency in the right mandible incidentally discovered during a routine dental radiographic examination; and (2) conduct a review of the literature to describe clinicopathological features and management of intraosseous jaw leiomyoma (IJL). A total of 17 articles describing 18 cases of IJL satisfied the selection criteria; including the present patient, to date a total of 19 cases of IJL have been reported. IJL occurs mainly in young patients (36.8 percent), more often in boys (1:5:1 male-to-female ratio), and reaches a larger size in children than in adults. The treatment of choice for IJL is surgical excision, which should be as minimally invasive as possible, especially in children.

Downward displacement of cerebellar tonsils more than 5 mm below the foramen magnum is named as Chiari type I malformation and named benign tonsillar ectopia if herniation is less than 3 mm. It does not just depend on congenital causes. There are also some reasons for acquired Chiari Type 1 and benign tonsillar ectopia/herniation. Trauma is one of them. Trauma may increase tonsillar ectopia or may be the cause of new-onset Chiari type 1. The relationship between the tonsil contusion and its position is unclear. We present a case of pediatric age group with tonsillar herniation with a hemorrhagic contusion. Only 1 case has been presented so far in the literature. A case with unilateral tonsil contusion has not been presented to date. We will discuss the possible reasons for taking the place of the tonsils to the above level of the foramen magnum in the follow-up period, by looking at the literature. PMID:29104687

The application of hybrid artificial intelligence systems for forecasting

NASA Astrophysics Data System (ADS)

Lees, Brian; Corchado, Juan

1999-03-01

The results to date are presented from an ongoing investigation, in which the aim is to combine the strengths of different artificial intelligence methods into a single problem solving system. The premise underlying this research is that a system which embodies several cooperating problem solving methods will be capable of achieving better performance than if only a single method were employed. The work has so far concentrated on the combination of case-based reasoning and artificial neural networks. The relative merits of artificial neural networks and case-based reasoning problem solving paradigms, and their combination are discussed. The integration of these two AI problem solving methods in a hybrid systems architecture, such that the neural network provides support for learning from past experience in the case-based reasoning cycle, is then presented. The approach has been applied to the task of forecasting the variation of physical parameters of the ocean. Results obtained so far from tests carried out in the dynamic oceanic environment are presented.

Implicit Large Eddy Simulation of a wingtip vortex at Rec =1.2x106

2015-11-01

We present recent developments in numerical methods for performing a Large Eddy Simulation (LES) of the formation and evolution of a wingtip vortex. The development of these vortices in the near wake, in combination with the large Reynolds numbers present in these cases, make these types of test cases particularly challenging to investigate numerically. To demonstrate the method's viability, we present results from numerical simulations of flow over a NACA 0012 profile wingtip at Rec = 1.2 x106 and compare them against experimental data, which is to date the highest Reynolds number achieved for a LES that has been correlated with experiments for this test case. Our model correlates favorably with experiment, both for the characteristic jetting in the primary vortex and pressure distribution on the wing surface. The proposed method is of general interest for the modeling of transitioning vortex dominated flows over complex geometries. McLaren Racing/Royal Academy of Engineering Research Chair.

Immune checkpoint inhibitors, such as ipilimumab (an anti-CTLA4 antibody), have become a commonly used therapy in cancer. To date, safety data of patients with underlying autoimmune disease is limited. We present a case of a patient with rheumatoid arthritis who was diagnosed of a BRAF-mutant metastatic melanoma. The patient was treated with ipilimumab and presented with high-grade colitis requiring immunosuppressors. Despite of the immune-related adverse event, no exacerbation of the rheumatoid arthritis was observed and the patient achieved a complete response. This case report contributes to the scarce literature on the use of immune checkpoint inhibitors in patients with an underlying autoimmune condition. PMID:27843587

Diethylstilbestrol (DES) was used widely in the late 1940s in an attempt to prevent adverse pregnancy outcomes. In 1971 the US Food and Drug Administration proscribed its use for pregnancy support secondary to its association with clear cell adenocarcinoma of the vagina. Several studies in animal models demonstrated an association with endometrial cancer among offspring following in utero DES exposure. To date, there is only one case report of endometrial cancer in women exposed to DES in utero. We present the first case, to our knowledge, of a woman exposed to DES in utero who presented with double primaries of clear cell cancer of the vagina concomitant with endometrial cancer.

Raoultella planticola bacteremia following consumption of seafood

Lam, Philip W; Salit, Irving E

2014-01-01

Raoultella planticola is a Gram-negative bacillus commonly found in water, soil and aquatic environments. There have only been 16 cases of R planticola infection documented in the literature to date. R planticola possesses the ability to convert histidine to histamine and can produce symptoms of scombroid poisoning when poorly prepared seafood is consumed in large amounts. The present report describes a case involving a 56-year-old woman who presented with R planticola bacteremia and symptoms consistent with cholangitis four days after consuming a seafood salad containing squid and octopus. She was successfully treated with intravenous ceftriaxone followed by oral ciprofloxacin. Recent chemotherapy, proton pump inhibitor use and altered biliary flow secondary to hepatic metastases may have been contributing factors to the pathogenesis of disease. PMID:25285133

Drug rash, eosinophilia, and systemic symptoms syndrome is a type of drug hypersensitivity reaction characterized by the clinical triad of skin eruption, fever, and internal organ involvement. Drug rash, eosinophilia, and systemic symptoms syndrome has rarely been reported in association with vancomycin or in the pediatric population. There have only been four pediatric case reports of drug rash, eosinophilia, and systemic symptoms syndrome and three cases of drug rash, eosinophilia, and systemic symptoms syndrome involving vancomycin published in the English literature to date. We describe two pediatric cases of drug rash, eosinophilia, and systemic symptoms syndrome to illustrate the range in severity of presentation. The first case illustrates drug rash, eosinophilia, and systemic symptoms syndrome associated with vancomycin exposure in a 14-yr-old boy with Duchenne muscular dystrophy after posterior spinal fusion, whose clinical presentation was indistinguishable from toxic shock syndrome. The second case illustrates a milder and more typical presentation of drug rash, eosinophilia, and systemic symptoms syndrome in a 14-yr-old boy being treated with minocycline for acne. We also present a review of the literature relevant to this syndrome. : Drug rash, eosinophilia, and systemic symptoms syndrome is relatively unknown among general pediatricians and pediatric intensivists and may potentially become more common with the increasing use of long-term medications in the pediatric population. Our cases demonstrate the importance of an awareness of drug rash, eosinophilia, and systemic symptoms syndrome among general pediatricians and pediatric intensivists because drug rash, eosinophilia, and systemic symptoms syndrome may present in any range of severity, from indolent illness to frank and refractory shock.

Does Angiotensin-Converting Enzyme Inhibitor and β-Blocker Use Reduce the Risk of Primary Liver Cancer? A Case-Control Study Using the U.K. Clinical Practice Research Datalink.

It has been suggested that use of the antihypertensive drugs angiotensin-converting enzyme (ACE) inhibitors and β-blockers may decrease the risk of primary liver cancer; thus, the objective of this study was to evaluate whether use of ACE inhibitors and/or β-blockers is associated with a lower risk of liver cancer. Nested case-control study. United Kingdom Clinical Practice Research Datalink. We identified 490 cases with hypertension and a first-time (incident) diagnosis of primary liver cancer between 1988 and 2011. To account for an induction period, the index date was defined as the date of the first recorded liver cancer diagnosis minus 1 year. Controls were selected from patients with hypertension in the CPRD during the study period with a recorded diagnosis of hypertension who had no diagnosis of liver cancer and were free of any other cancer (except nonmelanoma skin cancer) before the index date; they were matched up to a 4:1 ratio to cases based on index date (same index date as that of their matched case), age (same year of birth), sex, general practice, and number of years of recorded history in the CPRD before the index date (1909 controls). Both cases and controls were required to have at least 2 years of recorded activity in the database before the index date. Exposure was defined as receipt of two or more prescriptions for ACE inhibitors and/or β-blockers before the index date; the reference group was nonuse (0-1 prescription) of ACE or β-blocker prescriptions before the index date. We also examined the effect of duration of use and, separately, the effect of individual drugs within each medication class on risk of liver cancer, and conducted analyses restricted to patients without liver disease or diabetes mellitus. Conditional logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs). No association was found between use of ACE inhibitors and/or β-blockers and the risk of liver cancer compared with nonuse (adjusted OR 1.14, 95% CI 0.85-1.55). No significant differences were noted in risk by duration of use or by individual drugs, or after restricting the analyses to patients without diabetes or liver disease. Use of ACE inhibitors and/or β-blockers was not associated with reduced risk of primary liver cancer compared with nonuse of these drugs in persons with hypertension. © 2016 Pharmacotherapy Publications, Inc.

Sarcoidosis affects multiple organs including lung, heart and kidney. Sarcoidosis causes hypercalcemia, hypergammaglobulinemia, and rarely, granulomatous interstitial nephritis, resulting in renal stromal damage. Granulomatous interstitial nephritis is characterized as interstitial nephritis with noncaseating epithelioid granulomas. Diagnosing granulomatous interstitial nephritis before patient's death is challenging; hence, only few cases proven by renal biopsy have been reported till date. We present a case of acute kidney injury caused by granulomatous interstitial nephritis as a renal manifestation of sarcoidosis proven by renal biopsy, which can be confirmed by 18 F-fluorodeoxyglucose positron emission tomography/computed tomography. Glucocorticoid therapy was helpful for improving and maintaining her renal function over a 6-year period.

To date, the only instance of tick-borne encephalitis (TBE) in Japan was reported from the southern part of Hokkaido Island in 1993; no other cases have been reported since then. We herein report the first case of TBE reported in the central part of Hokkaido Island, and describe the fatal clinical course of a patient who presented with meningoencephalomyelitis, which partly involved the nerve root. Magnetic resonance imaging (MRI) of the patient's cranium and spine revealed characteristic central nervous system involvement. Our case report is extremely relevant to efforts to protect public health and for precautions against TBE pandemics.

To present a case of bilateral vocal fold immobility (BVCI) in a patient with acromegaly and review the current literature describing this presentation. Case report and literature review. Academic tertiary care center. English language literature search of online journal databases. A 56-year-old man presented with 3 months of progressive stridor and shortness of breath. Transnasal flexible endoscopy revealed BVCI. A tracheostomy was performed to secure his airway. Further history was suggestive of acromegaly and imaging demonstrated a pituitary macroadenoma. The diagnosis of acromegaly was made. The patient was treated with octreotide followed by an endoscopic trans sphenoidal resection of the pituitary adenoma. Sixteen months after his initial presentation, a right laser arytenoidectomy was performed and the patient was subsequently decannulated. In the literature to date, 11 cases of BVCI in acromegaly have been reported. These patients often present with stridor and require a tracheostomy. With treatment of their acromegaly, these patients may regain vocal fold mobility and may be decannulated. Acromegaly with BVCI is a rare presentation. Acute management of the airway of patients with acromegaly presenting with BVCI typically requires a tracheostomy. A period of 15 months should be allowed for restoration of vocal fold mobility before airway opening procedures are considered. Copyright © 2016 The Voice Foundation. Published by Elsevier Inc.

Dating the Origin of Language Using Phonemic Diversity

PubMed Central

2012-01-01

Language is a key adaptation of our species, yet we do not know when it evolved. Here, we use data on language phonemic diversity to estimate a minimum date for the origin of language. We take advantage of the fact that phonemic diversity evolves slowly and use it as a clock to calculate how long the oldest African languages would have to have been around in order to accumulate the number of phonemes they possess today. We use a natural experiment, the colonization of Southeast Asia and Andaman Islands, to estimate the rate at which phonemic diversity increases through time. Using this rate, we estimate that present-day languages date back to the Middle Stone Age in Africa. Our analysis is consistent with the archaeological evidence suggesting that complex human behavior evolved during the Middle Stone Age in Africa, and does not support the view that language is a recent adaptation that has sparked the dispersal of humans out of Africa. While some of our assumptions require testing and our results rely at present on a single case-study, our analysis constitutes the first estimate of when language evolved that is directly based on linguistic data.

SHRIMP U-Pb detrital zircon dating to check subdivisions in metamorphic complexes: a case of study in the Nevado-Filábride complex (Betic Cordillera, Spain)

Santamaría-López, Ángel; Sanz de Galdeano, Carlos

2018-04-01

U-Pb dating on inherited detrital zircons has been applied to obtain the probable maximum age of deposition of the detrital protolith of the Nevado-Filábride complex (Betic Cordillera, Spain). Five of eight samples correspond to the lower part of the lithologic sequence of this complex, where radiometric dating of metasediments has not been presented till the present. The youngest age populations in the majority of samples are Carboniferous. The estimation of the maximum age of deposition in the lower and upper units is 349.1 ± 1.6 and 334.6 ± 2.9 Ma, respectively. In addition, samples show common age populations at ca. 490-630 and ca. 910-1010 Ma. Observations agree with the Carboniferous to early Permian U-Pb ages previously obtained in orthogneisses levels which are situated in the upper part of the complex. Combination of the minimum age of deposition deducible from the orthogneisses studies and the maximum ages of deposition obtained from the detrital zircons of this work, allow establishing the deposition of de studied lithological succession comprised between ca. 282 and 349 Ma or a shorter period.

Northern peatland initiation lagged abrupt increases in deglacial atmospheric CH4.

PubMed

Reyes, Alberto V; Cooke, Colin A

2011-03-22

Peatlands are a key component of the global carbon cycle. Chronologies of peatland initiation are typically based on compiled basal peat radiocarbon (14C) dates and frequency histograms of binned calibrated age ranges. However, such compilations are problematic because poor quality 14C dates are commonly included and because frequency histograms of binned age ranges introduce chronological artefacts that bias the record of peatland initiation. Using a published compilation of 274 basal 14C dates from Alaska as a case study, we show that nearly half the 14C dates are inappropriate for reconstructing peatland initiation, and that the temporal structure of peatland initiation is sensitive to sampling biases and treatment of calibrated 14C dates. We present revised chronologies of peatland initiation for Alaska and the circumpolar Arctic based on summed probability distributions of calibrated 14C dates. These revised chronologies reveal that northern peatland initiation lagged abrupt increases in atmospheric CH4 concentration at the start of the Bølling-Allerød interstadial (Termination 1A) and the end of the Younger Dryas chronozone (Termination 1B), suggesting that northern peatlands were not the primary drivers of the rapid increases in atmospheric CH4. Our results demonstrate that subtle methodological changes in the synthesis of basal 14C ages lead to substantially different interpretations of temporal trends in peatland initiation, with direct implications for the role of peatlands in the global carbon cycle.

A numerical approach to 14C wiggle-match dating of organic deposits: best fits and confidence intervals

NASA Astrophysics Data System (ADS)

Blaauw, Maarten; Heuvelink, Gerard B. M.; Mauquoy, Dmitri; van der Plicht, Johannes; van Geel, Bas

2003-06-01

14C wiggle-match dating (WMD) of peat deposits uses the non-linear relationship between 14C age and calendar age to match the shape of a sequence of closely spaced peat 14C dates with the 14C calibration curve. A numerical approach to WMD enables the quantitative assessment of various possible wiggle-match solutions and of calendar year confidence intervals for sequences of 14C dates. We assess the assumptions, advantages, and limitations of the method. Several case-studies show that WMD results in more precise chronologies than when individual 14C dates are calibrated. WMD is most successful during periods with major excursions in the 14C calibration curve (e.g., in one case WMD could narrow down confidence intervals from 230 to 36 yr).

Long-term follow-up after cervical cancer treatment and subsequent successful surrogate pregnancy.

Agorastos, T; Zafrakas, M; Mastrominas, M

2009-08-01

Preservation of fertility is a major concern for premenopausal women after diagnosis of cervical cancer. Successful surrogate pregnancy after treatment for cervical cancer has very rarely been reported. In the present report, a case of successful surrogate pregnancy after radical hysterectomy, lymphadenectomy and ovarian transposition for cervical cancer, followed by radiation therapy, is presented. After stimulation of the transposed ovaries using the short gonadotrophin-releasing hormone (GnRH) analogue protocol, four oocytes were retrieved transabdominally from the genetic mother. IVF followed and two embryos were transferred to the surrogate mother, leading to an uneventful singleton pregnancy, and ultimately normal vaginal delivery of a healthy female infant at term. The unique aspect in this case is the long-lasting favourable outcome for both genetic mother and child, observed during 8.5 years of follow-up, the longest follow-up period reported to date in such cases.

Primary synovial sarcoma (SS) of the kidney is a rare neoplasm and its presenting features are similar to other common renal tumors, making early diagnosis difficult. To date, few cases have been reported in the literature. Primary renal SSs can exist in either a monophasic or a biphasic pattern, the former being more common and tending to have a better prognosis than the biphasic variant. Herein we describe a case of primary renal SS that was diagnosed based on histopathology and immunohistochemistry after radical nephrectomy. Fusion gene product analysis was also done by FISH and RT-PCR. Patient follow-up and literature review are presented, focused on systemic therapy. We highlight that these tumors should be correctly diagnosed as clinical results and specific treatment are distinct from primary epithelial renal cell carcinoma. Adjuvant chemotherapy should be tailored for each patient in the management of disease, although its role still remains unclear. PMID:24137053

  The purpose of the present study was to evaluate the correlation between clinical and histopathological diagnoses of periapical inflammatory lesions, focusing mainly on cystic conditions.   Files dating from 1998 to 2006 at the Oral Pathology Laboratory, School of Dentistry, Alfenas Federal University, Brazil, were reviewed to identify cases with histopathological diagnoses of periapical inflammatory lesions. A total of 1788 files were analyzed, and 255 cases were identified with clinical diagnoses of periapical inflammatory lesions.   The most prevalent clinical diagnosis was apical periodontal cyst (59%), followed by periapical granuloma (20%), and dentoalveolar abscess (2%). After histopathological analysis, 53% of the cases represented apical periodontal cyst, 42% periapical granuloma, and 5% dentoalveolar abscess.   The outcomes of the present study show a high prevalence of periapical cysts among periapical inflammatory lesions. Moreover, this study highlights the importance of histopathological evaluation for the correct diagnosis of periapical inflammatory lesions. © 2011 Blackwell Publishing Asia Pty Ltd.

2017-05-16

Cuticular hydrocarbons (CHC) have been successfully used in the field of forensic entomology for identifying and ageing forensically important blowfly species, primarily in the larval stages. However in older scenes where all other entomological evidence is no longer present, Calliphoridae puparial cases can often be all that remains and therefore being able to establish the age could give an indication of the PMI. This paper examined the CHCs present in the lipid wax layer of insects, to determine the age of the cases over a period of nine months. The two forensically important species examined were Calliphora vicina and Lucilia sericata. The hydrocarbons were chemically extracted and analysed using Gas Chromatography - Mass Spectrometry. Statistical analysis was then applied in the form of non-metric multidimensional scaling analysis (NMDS), permutational multivariate analysis of variance (PERMANOVA) and random forest models. This study was successful in determining age differences within the empty cases, which to date, has not been establish by any other technique.

Finger drop sign-Characteristic pattern of distal weakness in Guillain-Barré Syndrome: A case report and review of the literature.

PubMed

Chee, Yong Chuan; Ong, Beng Hooi

2018-01-01

Guillain-Barré Syndrome is an acquired acute autoimmune polyradiculoneuropathy that commonly presents with limb weakness and occasional cranial nerve, respiratory and autonomic involvement. Although the classic description of Guillain-Barré Syndrome is that of a demyelinating neuropathy with ascending weakness, predominant bilateral finger drop as presenting feature has rarely been reported. A characteristic pattern of weakness involving the extensor components of the fingers known as "finger drop sign" has been first described to be specific in acute motor axonal neuropathy form of Guillain-Barré Syndrome in the literature. We report a case of acute motor-sensory axonal neuropathy, which showed characteristic pattern of predominant finger extensor weakness, and provide a summary of all reported cases to date. While previous reports suggested that this is a sign that carries good prognosis, our case report suggested otherwise as the patient succumbed to respiratory and autonomic complications. Further studies are needed to evaluate the clinical significance of this peculiar sign.

To date, only one case of BK polyomavirus (BKPyV) encephalitis combined with transplant-associated thrombotic microangiopathy has been reported in an hematopoietic stem cell transplantation (HCT) recipient. We report the case of an HCT recipient who developed thrombotic microangiopathy and subsequent BKPyV encephalitis. She died despite treatment with cidofovir, ciprofloxacin, and intravenous immunoglobulin without improvement in mental status. Early suspicion of BKPyV encephalitis in an HCT recipient presenting with altered mental status and hemorrhagic cystitis is important. © 2016 John Wiley & Sons A/S.

Various possible causes of proventriculitis include virus, bacteria, fungus, protozoans, nematodes, biogenic amines and excessive copper sulphate. In the present case, parasites were found in the lumen of the proventriculus, gizzard and duodenum of a poultry bird. Characteristic features of the parasite were studied and confirmed as Ascaridia galli. An ulcerative proventriculitis evident as denuded superficial epithelium, sub-epithelial hemorrhages, infiltration of the inflammatory cells and fibrosis were seen at histopathology. Proventriculitis caused by A. galli has not been reported till date. Here, we report a case of ulcerative proventriculitis in a poultry bird caused by nematode, A. galli.

Leaflet embolisation from Duromedics valves: a report of two cases.

PubMed

Kumar, N; Balasundaram, S; Rickard, M; al Halees, Z; Duran, C M

1991-12-01

Embolization of parts of mechanical valves has been reported since the inception of prosthetic valve implantation. We report here two cases of embolization of one hemileaflet of a Duromedic bileaflet prosthesis in the mitral position due to a pivot fracture. Both presented with moderately severe mitral regurgitation and pulmonary edema and were successfully managed by replacement of the malfunctioning prostheses. The embolised disc was located in the left common iliac artery by abdominal ultrasound and removed by an inguinal, retroperitoneal approach with low morbidity. Both patients left hospital and are doing well to-date.

Composite Adrenocortical Carcinoma and Neuroblastoma in an Infant With a TP53 Germline Mutation: A Case Report and Literature Review.

Tang, Yue-Jia; Yu, Ting-Ting; Ma, Jing; Zhou, Ying; Xu, Min; Gao, Yi-Jin

2018-05-09

Li-Fraumeni syndrome is a kind of hereditary cancer predisposition syndromes, and is caused by TP53 gene mutation. Adrenocortical carcinoma (ACC) is commonly described as the most closely related tumor with this disease. Here, we present a case of a male infant with composite ACC and neuroblastoma who inherited a TP53 gene mutation from his mother, a 20-year-old carrier without any tumor to date. This TP53 gene mutation may be pathogenic and lead to composite malignancies of ACC and neuroblastoma.

Clinical characteristics and public health management of invasive meningococcal group W disease in the East Midlands region of England, United Kingdom, 2011 to 2013.

PubMed

Bethea, Jane; Makki, Sophia; Gray, Steve; MacGregor, Vanessa; Ladhani, Shamez

2016-06-16

In England and Wales, meningococcal disease caused by group W has historically been associated with outbreaks of disease among travellers to high-risk countries. Following a large outbreak associated with travel to the Hajj in 2000, the number of cases declined and, in 2008, only 19 laboratory-confirmed cases were identified nationally. In 2013, in the East Midlands region of England, eight cases of meningococcal disease caused by this serogroup were recorded, compared with six from 2011 to 2012. To explore this further, data for all cases with a date of onset between 1 January 2011 and 31 December 2013 were collected. Data collected included geographical location, clinical presentation and outcome. Fourteen cases were identified; two died as a result of their illness and two developed long-term health problems. No commonality in terms of geographical location, shared space or activities was identified, suggesting that group W is circulating endemically with local transmission. Clinical presentation was variable. Half presented with symptoms not typical of a classical meningococcal disease, including two cases of cellulitis, which may have implications for clinicians, in terms of timely identification and treatment, and public health specialists, for offering timely antibiotic chemoprophylaxis to close contacts.

2016-11-01

Inverse comorbidity is disease occurring at lower rates than expected among persons with a given index disease. The objective was to identify inverse comorbidity in MS. We performed a combined case-control and cohort study in a total nationwide cohort of cases with clinical onset of MS 1980-2005. We randomly matched each MS-case with five population controls. Comorbidity data were obtained from multiple, independent nationwide registries. Cases and controls were followed from January 1977 to the index date, and from the index date through December 2012. We controlled for false discovery rate and investigated each of eight pre-specified comorbidity categories: psychiatric, cerebrovascular, cardiovascular, lung, and autoimmune comorbidities, diabetes, cancer, and Parkinson's disease. A total of 8947 MS-cases and 44,735 controls were eligible for inclusion. We found no inverse associations with MS before the index date. After the index date, we found a decreased occurrence of chronic lung disease (asthma and chronic obstructive pulmonary disease) (HR 0.80 (95% CI 0.75-0.86, p<0.00025)) and overall cancer (HR 0.88 (95% CI 0.81-0.95, p=0.0005)) among MS-cases. This study showed a decreased risk of cancers and pulmonary diseases after onset of MS. Identification of inverse comorbidity and of its underlying mechanisms may provide important new entry points into the understanding of MS. Copyright © 2016 Elsevier B.V. All rights reserved.

Intradural Extramedullary Capillary Hemangioma in the Upper Cervical Spine: First Report.

PubMed

Bouali, Sofiene; Maatar, Nidhal; Bouhoula, Asma; Abderrahmen, Khansa; Kallel, Jalel; Jemel, Hafedh

2016-08-01

The occurrence of intradural extramedullary capillary hemangiomas is exceedingly rare. To date, only 39 cases of intradural extramedullary capillary hemangiomas have been reported in the English literature, and all of these cases have been described at the lumbar and thoracic spinal levels. To our knowledge, this report is the first case of capillary hemangiomas of the cervical spine in the literature. In general, this entity is misdiagnosed preoperatively as a neoplasm. A 29-year-old man presented with neck pain and progressive gait disturbance, and was diagnosed with an intradural extramedullary capillary hemangioma in the cervical region. Although rare, our case demonstrates that capillary hemangioma should be considered in the differential diagnosis of intradural extramedullary tumor of the cervical spine.

Extraocular Sebaceous Carcinoma on the Chest Wall – A Case Report

PubMed Central

SR, Diwakar; Thulasi, Vasudevaiah; Shenoy, K Manjunath

2014-01-01

Sebaceous carcinoma is a rare aggressive skin cancer derived from the epithelium of sebaceous glands. Sebaceous carcinomas are generally divided as ocular or extraocular locations. Very few cases of extra ocular sebaceous carcinomas have been reported till date. Among them only six cases were reported which were on the chest wall. We are hereby reporting the seventh case of sebaceous carcinoma on the chest wall. The disease exhibits diverse clinical presentations and histologic patterns, often resulting in a delay in an accurate diagnosis as it may mimic many other cutaneous malignancies like Dermatofibrosarcoma protuberance Basal Cell Carcinoma or Squamous Cell Carcinoma. High degree of suspicion is required and sebaceous carcinoma should be considered as one of the differential diagnosis for an ulceroproliferative growth on the skin. PMID:25121026

Cranio-orbital primary intraosseous haemangioma.

PubMed

Gupta, T; Rose, G E; Manisali, M; Minhas, P; Uddin, J M; Verity, D H

2013-11-01

Primary intraosseous haemangioma (IOH) is a rare benign neoplasm presenting in the fourth and fifth decades of life. The spine and skull are the most commonly involved, orbital involvement is extremely rare. We describe six patients with cranio-orbital IOH, the largest case series to date. Retrospective review of six patients with histologically confirmed primary IOH involving the orbit. Clinical characteristics, imaging features, approach to management, and histopathological findings are described. Five patients were male with a median age of 56. Pain and diplopia were the most common presenting features. A characteristic 'honeycomb' pattern on CT imaging was demonstrated in three of the cases. Complete surgical excision was performed in all cases with presurgical embolisation carried out in one case. In all the cases, histological studies identified cavernous vascular spaces within the bony tissue. These channels were lined by single layer of cytologically normal endothelial cells. IOCH of the cranio-orbital region is rare; in the absence of typical imaging features, the differential diagnosis includes chondroma, chondrosarcoma, bony metastasis, and lymphoma. Surgical excision may be necessary to exclude more sinister pathology. Intraoperative haemorrhage can be severe and may be reduced by preoperative embolisation.

Hodgkin's lymphoma arising in a case of mycosis fungoides: An unusual association.

Sharma, Preeti; Goyal, Surbhi; Yadav, Amit Kumar; Singh, Jasmeet; Mandal, Ashish Kumar

2018-01-01

Mycosis fungoides is a cutaneous T-cell lymphoma with a high risk for developing secondary malignancies, especially B-cell lymphoproliferative disorders. About 40 cases of Hodgkin's lymphoma associated with mycosis fungoides have been reported in literature till date. We report a case of a 35-year-old gentleman who presented with intensely itchy reddish lesions all over the body. Multiple skin biopsies taken from the lesions on scalp and back confirmed the clinical diagnosis of mycosis fungoides. While on treatment, he presented with multiple bilateral cervical, axillary and inguinal lymphadenopathy 9 years after the primary diagnosis of mycosis fungoides. Excision biopsy of a cervical lymph node revealed partial effacement of architecture by a tumor comprising polymorphous background. Histopathology and immunohistochemistry revealed a diagnosis of Hodgkin's lymphoma - nodular sclerosis subtype. The patient was started on chemotherapy for stage IV Hodgkin's lymphoma. Our case emphasizes the importance of keeping secondary Hodgkin's lymphoma in mind while dealing with a patient of mycosis fungoides. Our case immunohistochemically supports the distinct etiopathogenesis of Epstein-Barr virus-negative Hodgkin's lymphoma vis-à-vis cutaneous mycosis fungoides.

Hepatic Cell Adenoma: A Report of Four Cases

Four patients with hepatic cell adenoma have been treated at the UCLA Hospital since 1965. The most recent was a 22-year-old woman who underwent subtotal resection of a giant hepatic cell adenoma after an unusual and confusing clinical presentation. The tumor may be the largest reported to date and may have excreted metabolically-active substances. Increased familiarity with the varying clinical and radiographic presentations of these rare tumors may facilitate earlier diagnosis and management. ImagesFig. 1.Fig. 2.Fig. 3.Fig. 6.Fig. 7.

Digital database of the Holocene tephras of the Mono-Inyo Craters, California

USGS Publications Warehouse

Bursik, Marcus; Sieh, Kerry

2013-01-01

This digital product comprises a collection of age and isopach data for the Holocene tephras of the Mono-Inyo Craters, California. Data on the most recent eruptions from this volcanic chain are relatively comprehensive, getting less so the further back in time. For the most recent eruptions to about 1,500 years ago, tephra beds within separate eruptive sequences have been studied and isopached. Before this, from about 2,000 years ago to about 5,000 years ago, there are insufficient data for isopaching. However, one isolated tephra of about 9,000 years ago was studied and isopached in detail. Regarding ages, there are many tens of radiocarbon ages that have been obtained on the Holocene Mono-Inyo volcanic products. The vast majority of these radiocarbon dates are associated with tephras at locales that can be considered distal (basically where the primary tephra is less than several centimeters (cm) thick). These dates represent carbon that was sequestered perhaps within several hundred years of the eruption but do not represent the ages of separate eruptive pulses. There are two reasons for this. In some cases, it is clear that the dated material is not associated with the eruption products. This is the case in some lake strata where carbon is either not physically close to a given tephra layer or where an age for a tephra layer was obtained by interpolation assuming a sedimentation rate. In other cases, it is not clear that a given tephra layer represents a primary tephra; in such cases the layer could instead be redeposited. At most distal localities (beyond about 5 kilometers (km) from the chain), there was no record made of whether tephra was primary or redeposited, and at these distances where tephra is thin, it is generally redeposited during later events such as fires or thunderstorms. These age data are not appropriate for use in dating the eruptive history of the volcanic chain, and are therefore not included in the present contribution. The carbon age data in the present contribution were obtained by careful consideration of the material being collected. In the best instances, carbon was collected from new growth on plants that were probably killed by an eruption event through burning and burial. Slightly poorer data were collected from burned and buried forest duff that is renewed frequently. Finally, some dates for older Holocene tephra layers at Black Lake, Nevada, downwind of the Mono-Inyo Craters, appear to allow correlation of the layers to proximal occurrences. In cases where these poorer data were collected but yielded ages statistically indistinguishable from better data, the poorer data were included in the analysis. In the most difficult cases, usually the furthest back in time, poorer data that were nevertheless statistically indistinguishable were weighted together to generate the age estimate. There are some known Holocene eruptions from the Mono-Inyo Craters that are not included in this tabulation, as so far a tephra has not been associated with the eruptions. A good example of this is the Java blocks. The Java block eruption, from a vent underlying the northwestern corner of Negit Island in Mono Lake, expelled numerous blocks that were rafted within the lake and that are mostly deposited on the southwestern and northern lakeshore. No tephra that can be correlated to this deposit has been found, and therefore the eruption is not included in this tabulation.

Blended learning in health education: three case studies.

PubMed

de Jong, Nynke; Savin-Baden, Maggi; Cunningham, Anne Marie; Verstegen, Daniëlle M L

2014-09-01

Blended learning in which online education is combined with face-to-face education is especially useful for (future) health care professionals who need to keep up-to-date. Blended learning can make learning more efficient, for instance by removing barriers of time and distance. In the past distance-based learning activities have often been associated with traditional delivery-based methods, individual learning and limited contact. The central question in this paper is: can blended learning be active and collaborative? Three cases of blended, active and collaborative learning are presented. In case 1 a virtual classroom is used to realize online problem-based learning (PBL). In case 2 PBL cases are presented in Second Life, a 3D immersive virtual world. In case 3 discussion forums, blogs and wikis were used. In all cases face-to-face meetings were also organized. Evaluation results of the three cases clearly show that active, collaborative learning at a distance is possible. Blended learning enables the use of novel instructional methods and student-centred education. The three cases employ different educational methods, thus illustrating diverse possibilities and a variety of learning activities in blended learning. Interaction and communication rules, the role of the teacher, careful selection of collaboration tools and technical preparation should be considered when designing and implementing blended learning.

Estimating sowing and harvest dates based on the Asian summer monsoon

NASA Astrophysics Data System (ADS)

Mathison, Camilla; Deva, Chetan; Falloon, Pete; Challinor, Andrew J.

2018-05-01

Sowing and harvest dates are a significant source of uncertainty within crop models, especially for regions where high-resolution data are unavailable or, as is the case in future climate runs, where no data are available at all. Global datasets are not always able to distinguish when wheat is grown in tropical and subtropical regions, and they are also often coarse in resolution. South Asia is one such region where large spatial variation means higher-resolution datasets are needed, together with greater clarity for the timing of the main wheat growing season. Agriculture in South Asia is closely associated with the dominating climatological phenomenon, the Asian summer monsoon (ASM). Rice and wheat are two highly important crops for the region, with rice being mainly cultivated in the wet season during the summer monsoon months and wheat during the dry winter. We present a method for estimating the crop sowing and harvest dates for rice and wheat using the ASM onset and retreat. The aim of this method is to provide a more accurate alternative to the global datasets of cropping calendars than is currently available and generate more representative inputs for climate impact assessments. We first demonstrate that there is skill in the model prediction of monsoon onset and retreat for two downscaled general circulation models (GCMs) by comparing modelled precipitation with observations. We then calculate and apply sowing and harvest rules for rice and wheat for each simulation to climatological estimates of the monsoon onset and retreat for a present day period. We show that this method reproduces the present day sowing and harvest dates for most parts of India. The application of the method to two future simulations demonstrates that the estimated sowing and harvest dates are successfully modified to ensure that the growing season remains consistent with the internal model climate. The study therefore provides a useful way of modelling potential growing season adaptations to changes in future climate.

Imaging findings of anaplastic astrocytoma in a child with maple syrup urine disease: a case report.

PubMed

2015-09-01

Maple syrup urine disease (MSUD) is an inborn error of branched-chain amino acid metabolism, which usually presents in childhood with encephalopathy due to cerebral edema and dysmyelination. Even with treatment, metabolic stressors may precipitate later episodes of acute decompensation. Changes related to cerebral and white matter edema have been described by magnetic resonance imaging (MRI), and imaging can aid in both initial diagnosis and evaluation of decompensation. To date, there are no published known reports of cancer in patients with MSUD. Here, we present the first case report of an anaplastic astrocytoma in a teenager with MSUD, with a discussion of imaging findings and the use of magnetic resonance spectroscopy (MRS) to help distinguish between tumor and metabolic changes.

Ecstasy-Associated Pneumomediastinum

Marasco, Silvana F; Lim, H Kiat

2007-01-01

INTRODUCTION Ecstasy, also known as MDMA (3,4, methylenedioxymethamphetamine), is a popular illicit party drug amongst young adults. The drug induces a state of euphoria secondary to its stimulant activity in the central nervous system. PATIENTS AND METHODS A database review at two major inner city hospitals was undertaken to identify patients presenting with pneumomediastinum and their charts reviewed. A Medline review of all reported cases of pneumomediastinum associated with ecstasy abuse was undertaken. RESULTS A total of 56 patients presenting with pneumomediastinum were identified over a 5-year period. Review of the charts revealed a history of ecstasy use in the hours prior to presentation in six of these patients, representing the largest series reported to date. CONCLUSIONS Review of previously reported cases reveals the likely mechanism is due to Valsalva manoeuvre during periods of extreme physical exertion, and not a direct pharmacological effect of the drug.

Cecal duplication is a rare congenital anomaly and to the best of our knowledge, only 43 cases have been reported in the literature till date. Most of them present within the first year of life. They can mimic intussusception, and the delay in diagnosis can lead to high morbidity. A five-year boy presented with pain abdomen for a week. He was found to have ileocolic intussusception. The intussusception could only be partially reduced by the hydrostatic method. On laparotomy, a submucosal solid mass was found in the cecum with multiple enlarged lymph nodes. Mass was resected with clear margins and lymph nodes sampled. Histopathology was conclusive of cecal duplication. Post-operative course was uneventful, and the child is thriving well, last reviewed at three-year follow-up. Incomplete reduction of intussusception, intussusception with atypical presentation or intussusception in atypical age group should alert to the possibility of cecal duplication.

Identification of abnormalities in the developmental trajectory during infancy of future schizophrenia cases offers the potential to reveal pathogenic mechanisms of this disorder. Previous studies of head circumference in pre-schizophrenia were limited to measures at birth. The use of growth acceleration of head circumference (defined as the rate of change in head circumference) provides a more informative representation of the maturational landscape of this measure compared to studies based on static head circumference measures. To date, however, no study has examined whether HC growth acceleration differs between pre-schizophrenia cases and controls. In the present study, we employed a nested case control design of a national birth cohort in Finland. Cases with schizophrenia or schizoaffective disorder (N=375) and controls (N=375) drawn from the birth cohort were matched 1:1 on date of birth (within 1 month), sex, and residence in Finland at case diagnosis. Longitudinal data were obtained on head circumference from birth through age 1. Data were analyzed using a new nonparametric Bayesian inversion method which allows for a detailed understanding of growth dynamics. Adjusting for growth velocity of height and weight, and gestational age, there was significantly accelerated growth of head circumference in females with schizophrenia from birth to 2 months; the findings remained significant following Bonferroni correction (p < 0.0125). This is the first study to report abnormal HC growth acceleration, a more sensitive measure of somatic developmental deviation of this measure, in schizophrenia. PMID:27818077

Luminescence dating of river terrace formation - methodological challenges and complexity of result interpretation: a case study from the headwaters of the River Main, Germany

River terraces are widespread geomorphic features of Quaternary landscapes. Besides tectonics, their formation is predominantly controlled by climatic conditions. Changes in either conditions cause changes in fluvial discharge and sediment load. Therefore, fluvial terraces are widely used as important non-continuous sedimentary archives for paleotectonic and paleoenvironmental reconstruction. The informative value of fluvial archives and their significance for paleoenvironmental research, however, strongly depend on a precise dating of the terrace formation. Over the last decades, various luminescence dating techniques have successfully been applied on fluvial deposits and were able to provide reliable age information. In contrast to radiocarbon dating, modern luminescence dating techniques provide an extended dating range, which enables the determination of age information for fluvial and other terrestrial archives far beyond the last glacial-interglacial cycle. Due to the general abundance of quartz and feldspar minerals, there is almost no limitation of dateable material, so that luminescence dating methods can be applied on a wide variety of deposits. When using luminescence dating techniques, however, some methodological difficulties have to be considered. Due to the mechanism of fluvial transport, this is especially true for fluvial sediments, for which two major problems have been identified to be the main reasons of incorrect age estimations: (1) incomplete resetting of the luminescence signal during transport and (2) dosimetric inaccuracies as a result of the heterogeneity of terrace gravels. Thus, luminescence dating techniques are still far from being standard methods for dating fluvial archives and the calculated sedimentation ages always demand a careful interpretation. This contribution reveals some of the difficulties that may occur when luminescence dating techniques are applied on river terraces and illustrates several strategies used for overcoming these problems and for determining correct sedimentation ages. The presented results are based on a case study, located in the headwaters of the River Main, the longest right bank tributary of the Rhine drainage system. Here, within an oversized dry valley in Northern Bavaria (Germany), five Pleistocene terraces are distinguished. The terraces are interpreted as the result of a complex landscape evolution, which is characterized by multiple river deflections. The need for a careful interpretation of luminescence results is illustrated by some optically stimulated luminescence (OSL) ages calculated for the youngest of these five Pleistocene terraces. These results show different sedimentation ages of samples originating from the same morphological unit. Thus, these ages may be interpreted as evidence for a diachronic character of river incision and, hence, point to the complexity of fluvial systems' response to climatically and/or tectonically forced changes in local and regional paleoenvironmental conditions.

The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome) is a rare autosomal dominant syndrome caused due to mutations in the patched gene found on chromosome arm 9 q. It shows high penetrance and variable expressivity; is characterized by basal cell carcinomas, odontogenic keratocysts, palmar and/or plantar pits and ectopic calcifications of the falx cerebri. Until date, very few cases of GGS have been reported in India. Early diagnosis and treatment as well as genetic counseling are essential for this syndrome. A rare case report of a patient with characteristic features of GGS diagnosed at a rural dental college of Gujarat, India is presented here. This case report draws attention of the valuable role of dentist in diagnosis and early management of this syndrome.

This essay examines my work as expert witness in the case of U.S. v. Michigan, a Indigenous use-rights case. I was charged with parsing the intention of a specific article of the 1836 Treaty of Washington compelling land cession by Anishinaabe peoples and with writing a history of land use in the area from that date to the present for the Chippewa Ottawa Resource Authority (my employer). The challenges were not only methodological (how do you estimate use from ownership?) and epistemological (what constitutes proof that will satisfy both historians and lawyers?), but also sociological and psychological: what happens when an associate professor puts her progress toward full professor on hold for the sake of a court case?

Mothers’ Reports of Play Dates and Observation of School Playground Behavior of Children Having High-Functioning Autism Spectrum Disorders

PubMed Central

Frankel, Frederick D.; Gorospe, Clarissa M.; Chang, Ya-Chih; Sugar, Catherine A.

2010-01-01

Background Children with high functioning autism spectrum disorders (ASD) are generally included with typically developing peers at school. They have difficulties interacting with peers on the school play ground. Previous literature suggests that having play dates in the home may be related to better peer acceptance at school. Methods This study examines the relationship between mother-reported play date frequency and amount of conflict, and peer interaction observed on the school playground for a sample of 27 boys and 4 girls meeting structured interview and observation criteria for ASD. Measures of intellectual functioning, adaptive behavior, and social skills were included in a stepwise regression analysis to account for their impact on relationships between maternal play date reports, general peer acceptance at school (as rated by the child’s teacher) and observations of school playground behavior. Results Results revealed that children with autism spectrum disorders who had more play dates in their home tended to spend a greater amount of time engaged in behaviors such as mutual offering of objects, conversing and other turn taking activities with peers on the school playground. They also received more positive responses to their overtures from peers. These relationships remained highly significant even after accounting for other demographic, general social, and cognitive variables. Conclusions The present results suggest that play date frequency is strongly related to school playground behavior. Due to the design of this study, future research must assess whether play dates in the home promote better peer relationships on the playground or the reverse. In either case, the assessment of play dates, as well as observation of spontaneous unsupervised social interactions are important outcome measures to consider in social skills interventions for children with high functioning ASD.

Achondroplasia with 47, xxy karyotype: a case report of the neonatal diagnosis of an extremely unusual association

PubMed Central

2012-01-01

Background The association of achondroplasia and Klinefelter syndrome is extremely rare. To date, five cases have been previously reported, all of them diagnosed beyond the postnatal period, and only one was molecularly characterized. We describe the first case of this unusual association diagnosed in the neonatal period, the clinical findings and the molecular studies undertaken. Case presentation The boy was born at term with clinical and radiological features indicating the diagnosis of achondroplasia or hypochondroplasia combined with the prenatal karyotype of Klinefelter syndrome (47,XXY). Neonatal FGFR3 mutation screening showed that the newborn was heterozygous for the classic achondroplasia G340R mutation. Microsatellite marker analysis showed that the sex chromosome aneuploidy had arisen from a non-disjunction error in paternal meiosis I, with a recombination event in the pseudoautosomal region 1 (PAR1). Conclusion Specific mutation analysis is appropriate to confirm the clinical diagnosis of achondroplasia for appropriate diagnosis, prognosis, and genetic counseling, especially when the karyotype does not explain the abnormal prenatal sonographic findings. In the present case, a recombination event was observed in the PAR1 region, although recombinational events in paternally derived Klinefelter syndrome cases are much rarer than expected.

2018-01-01

Background: Anaplastic posterior fossa ganglioglioma in adults is exceedingly rare. To date, only one case of adult anaplastic posterior fossa ganglioglioma has been reported in the English literature and none has been described at the cerebellum. To our knowledge, this report is the third case of malignant posterior fossa ganglioglioma in adults and the first at the cerebellum. In general, this entity can be misdiagnosed preoperatively as a primary posterior fossa neoplasm, and by reporting our clinical and radiographic observations we want to add to the existing literature on this rare entity. Case Description: A 40-year-old man presented with a history of headaches and dizziness and progressive gait disturbance and was diagnosed with anaplastic ganglioglioma in the posterior fossa. Conclusions: Although rare, our case demonstrates that anaplastic ganglioglioma should be considered in the differential diagnosis of infratentorial tumors in adult patients. PMID:29527389

We report a rare case in which hemothorax occurred in addition to hemoperitoneum due to spontaneous rupture of hepatocellular carcinoma (HCC) originating from the caudate lobe of the liver. The case pertains to a 56-year-old female who was transported to our hospital for impaired consciousness due to hemorrhagic shock. Computed tomography (CT) demonstrated ruptured HCC originating from the caudate lobe and accompanying hemoperitoneum and right hemothorax. Hemostasis was carried out by transcatheter arterial embolization (TAE), and surgery was conducted approximately one month after TAE. In the present case, no lesions as possible sources of bleeding were observed inside the pleural cavity, and, moreover, the diaphragm had no abnormalities in the intraoperative findings, suggesting that blood from the ruptured tumor may have traversed the intact diaphragm to enter the right pleural cavity soon after the HCC rupture. However, to the best of our knowledge, no similar cases of HCC have been reported to date, and this case is thus believed to be very rare. This unusual phenomenon may therefore be strongly associated with the location of the ruptured tumor and the formation of a hematoma inside the omental bursa. We discuss the mechanism causing hemothorax in the present case and also review the previously reported cases of ruptured HCC complicated by hemothorax.

 Existing information on acute idiopathic scrotal edema relies on small case series and textbooks.  We searched reports with no date limits on acute idiopathic scrotal edema.  Thirty-seven studies were included. Sixteen case series addressed the prevalence of acute idiopathic scrotal edema among males with acute scrotum: among 3,403 cases, the diagnosis of acute idiopathic scrotal edema was made in 413 cases (12%). Twenty-four reports addressed history, findings, management, and course of acute idiopathic scrotal edema in 311 patients. The patients mostly ranged in age from 5 to 8 years, presented with acute scrotal redness and swelling, associated or not with mild pain. Ninety percent or more of the cases developed in patients without atopic diathesis and were not preceded by inguinoscrotal surgery, acute febrile illnesses, or trauma. They were afebrile; in good general condition; and presented without pruritus, nausea or vomiting, or abdominal pain. The lesions were bilateral in two-thirds and unilateral in one-third of the cases. The condition resolved spontaneously within 2 to 3 days without sequelae. Approximately 10% of the cases experienced a recurrence.  Acute idiopathic scrotal edema is a self-limiting condition that accounts for ≥ 10% of cases of acute scrotum in children and adolescents.

Malaria in U.S. military forces: a description of deployment exposures from 2003 through 2005.

Ciminera, Paul; Brundage, John

2007-02-01

U.S. service members are often deployed to regions endemic for malaria. Preventive measures play an important role in mitigating the risk of disease and adverse effects on mission performance. Currently, a large contingent of U.S. forces is deployed in malarious regions in southeast and southwest Asia. The purpose of this study was to describe malaria cases reported by the tri-service reportable medical events system in terms of exposure (deployment history) and latency of infection. We conducted a retrospective analysis of population health data routinely collected for disease surveillance. All malaria reports received into the Defense Medical Surveillance System by January 3, 2006 with a date of onset between January 1, 2000 and December 31, 2005 in which the individual diagnosed is a member of the active or reserve military components linked to personnel and deployment data were analyzed to determine assignment and deployment history. The main outcome measure was the ICD9-CM diagnosis of malaria (Plasmodium vivax, P. falciparum, P. ovale, P. malaria, and unspecified malaria) by date of onset and days from exposure. A total of 423 cases of malaria were reported during the study period. The Army (n = 325) and the Marine Corps (n = 46) had the highest number of reported cases. Plasmodium vivax (n = 242) and P. falciparum (n = 92) caused nearly four-fifths of all reported cases. During the period from 2003 through 2005, 34% of deployed cases were exposed to more than one malaria-endemic region. Seventy-four cases had been assigned in the Republic of Korea, and all were present in Korea during the high risk transmission period. Seventy-eight cases had documented service in Afghanistan; only 4 had off-season exposure and no other documented exposures. Sixty cases had documented exposure during Operation Iraqi Freedom (OIF). Only six seasonally exposed and six off seasonally exposed OIF cases had no other documented exposure. Fifty percent of Korean cases were diagnosed during an exposure season, and only 3% of Afghan cases were diagnosed during an exposure season. Soldiers in today's military can be exposed to more than one malaria-endemic region prior to diagnosis. This presents new complexities for disease monitoring and prevention policy development.

Northern peatland initiation lagged abrupt increases in deglacial atmospheric CH4

PubMed Central

Reyes, Alberto V.; Cooke, Colin A.

2011-01-01

Peatlands are a key component of the global carbon cycle. Chronologies of peatland initiation are typically based on compiled basal peat radiocarbon (14C) dates and frequency histograms of binned calibrated age ranges. However, such compilations are problematic because poor quality 14C dates are commonly included and because frequency histograms of binned age ranges introduce chronological artefacts that bias the record of peatland initiation. Using a published compilation of 274 basal 14C dates from Alaska as a case study, we show that nearly half the 14C dates are inappropriate for reconstructing peatland initiation, and that the temporal structure of peatland initiation is sensitive to sampling biases and treatment of calibrated 14C dates. We present revised chronologies of peatland initiation for Alaska and the circumpolar Arctic based on summed probability distributions of calibrated 14C dates. These revised chronologies reveal that northern peatland initiation lagged abrupt increases in atmospheric CH4 concentration at the start of the Bølling–Allerød interstadial (Termination 1A) and the end of the Younger Dryas chronozone (Termination 1B), suggesting that northern peatlands were not the primary drivers of the rapid increases in atmospheric CH4. Our results demonstrate that subtle methodological changes in the synthesis of basal 14C ages lead to substantially different interpretations of temporal trends in peatland initiation, with direct implications for the role of peatlands in the global carbon cycle.

Symptomatic Acute-on-Chronic Subdural Hematoma: A Clinicopathological Study.

PubMed

Castellani, Rudy J; Mojica-Sanchez, Gruschenka; Schwartzbauer, Gary; Hersh, David S

2017-06-01

The pathophysiology of acute-on-chronic subdural hematoma (ACSDH) is complex and incompletely understood. Evidence to date indicates that the overall process is initiated by rotational force with movement of the brain inside the skull, which exerts tensile strain and rupture of bridging veins, leading in turn to acute hemorrhage in the subdural potential space. This is followed by the proliferation of mesenchymal elements with angiogenesis and inflammation, which in turn becomes a substrate for repeated hemorrhage and expansion of the lesion. Given the prevalence of traumatic subdural processes in the forensic setting and the importance of proper assessment of timing, etiology, risk factors, and clinicopathological correlation, we studied 47 patients presenting to the University of Maryland Shock Trauma Center, all of whom underwent craniotomy with resection of the outer membrane due to symptomatic ACSDH. The surgically resected tissue was examined for histopathologic features in all cases. Our findings highlight that ACSDH is a condition precipitated by trauma that affects middle-aged and older adults, is relatively indolent, is unilateral or asymmetric, and has a low in-hospital mortality rate. Pathological analysis demonstrates a substantial outer membrane in all cases with varying degrees of inflammation and organization that cannot be precisely dated as a function of clinical presentation. The extrapolation of adult ACSDH to mixed acute and chronic subdural hemorrhage in the pediatric setting is problematic due to substantial differences in clinical presentation, severity of underlying brain injury, gross and microscopic findings, and outcome.

Cohen, J D; Thomas, E; Garnier, N; Hellier, I; Durand, L; Guilhou, J J; Baldet, P; Blotman, F

2000-11-01

Kaposi's disease is an angiogenic multifocal cancer process that has several forms, namely Mediterranean, African, HIV-associated, and secondary to a preexisting immunodepressive state (hematological disorder, corticosteroid therapy, immunodepressive treatment). Whatever its form, Kaposi's sarcoma is probably associated with a chronic viral human herpes type 8 infection (HHV8). This virus has been implicated in the pathogenesis of multiple myeloma (17 cases recorded to date). In the present study, a further case of Kaposi's sarcoma associated with multiple myeloma has been reported. However, Epstein-Barr virus, cytomegalovirus, hepatitis B and C, HIV and HHV8 serologies were negative. Radiotherapy on the lower limbs was initiated. It is concluded that HHV8 does not appear to play a pathogenic role in cases of multiple myeloma, given the rarity of the association between Kaposi's sarcoma/multiple myeloma/HHV8.

Anaplastic posterior fossa ganglioglioma in adults is exceedingly rare. To date, only one case of adult anaplastic posterior fossa ganglioglioma has been reported in the English literature and none has been described at the cerebellum. To our knowledge, this report is the third case of malignant posterior fossa ganglioglioma in adults and the first at the cerebellum. In general, this entity can be misdiagnosed preoperatively as a primary posterior fossa neoplasm, and by reporting our clinical and radiographic observations we want to add to the existing literature on this rare entity. A 40-year-old man presented with a history of headaches and dizziness and progressive gait disturbance and was diagnosed with anaplastic ganglioglioma in the posterior fossa. Although rare, our case demonstrates that anaplastic ganglioglioma should be considered in the differential diagnosis of infratentorial tumors in adult patients.

Wegener granulomatosis as an uncommon cause of panhypopituitarism in childhood.

2013-01-01

Wegener granulomatosis (WG) is a cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA)-associated, multi-system, necrotizing granulomatous vasculitis. Inflammation of the nasal or oral mucosa, and lung and kidney involvements are typical in the course of the disease. In rare cases, pituitary involvement may occur and cause panhypopituitarism. Pituitary involvement is very rare, and only two pediatric case reports have been published to date out of a total of 24 cases. This is a case report of an adolescent patient who presented with panhypopituitarism symptoms and was later diagnosed with WG. A 16-year-old female patient complained of fever, headache, purulent nasal discharge and severe muscle and joint pain. Additionally, she had polyuria and polydipsia. Investigations revealed a pituitary mass and panhypopituitarism. Positivity of c-ANCA and renal biopsy result compatible with WG confirmed the diagnosis.

A rare case of giant occipital meningocele with Dandy Walker Syndrome: Can it grow bigger than this?

2016-01-01

Association of Dandy-Walker syndrome with occipital meningocele (OMC) is extremely rare and about thirty cases are reported till date in the Western literature. However, OMC is classified by Talamonti et al . into small, large, and giant categories with respective diameters were upto 5 cm in small, large with 5-9 cm, and giant with >9 cm. Usually the size of OMC progressively increases as raised intracranial pressure leads to compensatory cerebrospinal fluid escape into sac with the growth of children. Authors report an interesting case of an 18-month-old female child with extra-gigantic OMC, whose size was almost same since birth, representing the first case of its kind, who underwent successful surgical repair. Clinical presentation, radiological features, and surgical management options in literature are reviewed briefly for this rare disease association.

The traumatic experience, which dates back to the Franco-Algerian War, could have gradually started making sense in the context of its onset and of the state in which the relationship between the patient and his father remained at the time. Something along the lines of an irrevocable mistake, irrevocable since logically referred to as a serious moral mistake on the part of the father towards his son, renders humanely comprehensible his upkeep of his atrocity as represented by the repetition of the revival symptoms.

Intrathecal patient-controlled analgesia (IT-PCA) through implanted intrathecal infusion pumps has been increasingly utilized for severe cancer and chronic noncancer pain management. However, its application for acute postoperative pain management has not been reported to date. We present a case of a patient with an implanted intrathecal pump for chronic nonmalignant back pain who underwent an extensive spinal fusion surgery. The IT-PCA functionality of her intrathecal pump was successfully integrated into her postoperative multimodal pain regimen. Hence, IT-PCA can be safely incorporated into acute postoperative pain management with vigilant monitoring and close multidisciplinary collaboration.

We report the case of a 55-year-old woman presenting with progressive memory impairment secondary to a transsphenoidal encephalocele involving her dominant medial temporal lobe. Her clinical deterioration was accompanied by radiological progression in the encephalocele's size and associated encephalomalacia. Through a temporal craniotomy, her encephalocele was resected and the defect closed. Baseline neuropsychological assessment indicated global cognitive impairment, but post-operatively, she reported improved memory and concentration. Standardized assessment reflected an improvement in perceptual skills and an associated improved recall of a complex figure. This is the first case report to date of a patient's memory improving following treatment of a basal encephalocele.

Mucoceles of the sphenoid sinus.

PubMed

Weaver, R G; Gates, G A

1979-01-01

Mucoceles of the sphenoid sinuses are uncommon; 60 cases have been reported in the world literature to date. Signs and symptoms are caused by local expansion of the mucocele and include headache (the most common symptom), ocular field deficits, external ophthalmoplegia (particularly the sixth cranial nerve), and proptosis. Radiologic correlation in the form of plain films and polytomorgraphy is the most reliable guide in the diagnosis of sphenoid sinus disease. Therapy of these lesions is surgical, and drainage can be achieved via the external ethmoid or sublabial transseptal route. Three cases are presented: two had classical findings and the third was conspicuous by the presence of aseptic meningitis in the absence of local findings.

Laugier-Hunziker syndrome: A case report and review of the literature.

PubMed

Rangwala, Sophia; Doherty, Christy B; Katta, Rajani

2010-12-15

Laugier-Hunziker syndrome (LHS) is a rare acquired disorder characterized by diffuse macular hyperpigmentation of the oral mucosa and, at times, longitudinal melanonychia. Although LHS is considered a benign disease with no systemic manifestations or malignant potential, it is important to rule out other mucocutaneous pigmentary disorders that do require medical management. Prompt clinical recognition also averts the need for excessive and invasive procedures and treatments. To date, only four cases have been reported in the United States. We present a 77-year-old man who had clinical features typical of LHS and we then provide a review of the literature on LHS and its mimickers.

Transition between morule-like and solid components may occur in solid-predominant adenocarcinoma of the lung: report of 2 cases with EGFR and KRAS mutations.

PubMed

Tajima, Shogo; Koda, Kenji

2015-01-01

A limited number of pulmonary adenocarcinoma cases with morule-like components have been described to date, and the most frequent histological subtype is papillary-predominant adenocarcinoma. Occasionally, this type of adenocarcinoma is associated with solid-predominant adenocarcinoma. EGFR mutations are predominant in adenocarcinoma with morule-like components, followed by ALK rearrangements. Herein, we present 2 cases of solid-predominant adenocarcinoma with morule-like components harboring either an EGFR or KRAS mutation. This KRAS-mutant case is the first to be associated with morule-like components, to the best of our knowledge. Both cases showed transition between micropapillary and morule-like components. Transition between morule-like and solid components was also observed in both cases. Although a few cases of solid-predominant adenocarcinoma have been shown to harbor morule-like components, this type of transition has not been previously well described. We surmised that the solid components of some EGFR-mutant adenocarcinomas might be derived from morule-like components.

Intra-grain Common Pb Correction and Detrital Apatite U-Pb Dating via LA-ICPMS Depth Profiling

NASA Astrophysics Data System (ADS)

Boyd, P. D.; Galster, F.; Stockli, D. F.

2017-12-01

Apatite is a common accessory phase in igneous and sedimentary rocks. While apatite is widely employed as a low-temperature thermochronometric tool, it has been increasingly utilized to constrain moderate temperature cooling histories by U-Pb dating. Apatite U-Pb is characterized by a thermal sensitivity window of 375-550°C. This unique temperature window recorded by the apatite U-Pb system, and the near-ubiquitous presence of apatite in igneous and clastic sedimentary rocks makes it a powerful tool able to illuminate mid-crustal tectono-thermal processes. However, as apatite incorporates only modest amounts of U and Th (1-10s of ppm) the significant amounts of non-radiogenic "common" Pb incorporated during its formation presents a major hurdle for apatite U-Pb dating. In bedrock samples common Pb in apatite can be corrected for by the measurement of Pb in a cogenetic mineral phase, such as feldspar, that does not incorporate U or from determination of a common Pb composition from multiple analyses in Tera-Wasserburg space. While these methods for common Pb correction in apatite can work for igneous samples, they cannot be applied to detrital apatite in sedimentary rocks with variable common Pb compositions. The obstacle of common Pb in apatite has hindered the application of detrital apatite U-Pb dating in provenance studies, despite the fact that it would be a powerful tool. This study presents a new method for the in situ correction of common Pb in apatite through the utilization of novel LA-ICP-MS depth profiling, which can recover U-Pb ratios at micron-scale spatial resolution during ablation of a grain. Due to the intra-grain U variability in apatite, a mixing line for a single grain can be generated in Tera-Wasserburg Concordia space. As a case study, apatite from a Variscan alpine granite were analyzed using both the single and multi-grain method, with both methods giving identical results. As a second case study the intra-grain method was then performed on detrital apatite from the Swiss Northern Alpine Foreland Basin, where the common Pb composition and age spectra of detrital apatite grains were elucidated. The novel intra-grain apatite method enables the correction for common Pb in detrital apatite, making it feasible to incorporate detrital apatite U-Pb dating in provenance and source-to-sink studies.

Describing the profile of victims and assaults by gunshot, where the outcome was death. An ecological study conducted in the city of Maceió/AL, in 2012. Data were collected from the death statements. The variables studied were: the death circumstances, gender, age, marital status, place, date, time, month and proportion according to the occurring neighborhood. The homicide mortality rate was 65.2 per 100,000 inhabitants, with 130.6 per 100,000 men and 7.8 per 100,000 women. Of the total number of homicides, 93.6% of the victims were men. The age group between 15 and 29 years of age was the most affected, with 68.8%. In 97.6% of cases the death occurred at the site of aggression, 74.1% in the streets. In relation to the date, 54.2% of cases occurred between Friday and Sunday. 59.7% of the homicides were concentrated in seven neighborhoods. The map of violence presented shows heterogeneous areas for the occurrence of assaults with firearms, characterizing the existing urban inequality in violence distribution.

From Shell Midden to Midden-Mound: The Geoarchaeology of Mound Key, an Anthropogenic Island in Southwest Florida, USA

2016-01-01

Mound Key was once the capital of the Calusa Kingdom, a large Pre-Hispanic polity that controlled much of southern Florida. Mound Key, like other archaeological sites along the southwest Gulf Coast, is a large expanse of shell and other anthropogenic sediments. The challenges that these sites pose are largely due to the size and areal extent of the deposits, some of which begin up to a meter below and exceed nine meters above modern sea levels. Additionally, the complex depositional sequences at these sites present difficulties in determining their chronology. Here, we examine the development of Mound Key as an anthropogenic island through systematic coring of the deposits, excavations, and intensive radiocarbon dating. The resulting data, which include the reversals of radiocarbon dates from cores and dates from mound-top features, lend insight into the temporality of site formation. We use these insights to discuss the nature and scale of human activities that worked to form this large island in the context of its dynamic, environmental setting. We present the case that deposits within Mound Key’s central area accumulated through complex processes that represent a diversity of human action including midden accumulation and the redeposition of older sediments as mound fill.

Gupta, Nitin; Dass, Arjun; Goel, Neha; Tiwari, Sandeep

2015-05-01

Tuberculous otitis media (TOM) is an uncommon, insidious, and frequently misdiagnosed form of tuberculosis (TB). In particular, TOM is usually secondary to direct transmission from adjacent organs, while the primary form has been rarely reported. The main aim of treatment is to start the patient on an antitubercular regime and early surgical intervention to decompress the facial nerve if involved. The case report of a twenty year-old male with bilateral tuberculous otitis media, who presented himself with fever followed by sequential bilateral facial nerve paralysis, bilateral profound hearing loss, and abdominal tuberculosis leading to intestinal perforation, is presented. To the best available knowledge and after researching literature, no such case depicting the extensive otological complications of tuberculosis has been reported till date. Tuberculosis of the ear is a rare entity and in most cases the clinical features resemble that of chronic otitis media. The diagnosis is often delayed due to varied clinical presentations and this can lead to irreversible complications. Early diagnosis is essential for prompt administration of antitubercular therapy and to prevent complications.

A Rare Case of Cavitary Lesion of the Lung Caused by Mycoplasma pneumoniae in an Immunocompetent Patient

PubMed Central

Dudekula, Rizwan Ahmed

2017-01-01

Mycoplasma pneumoniae is an atypical bacterium that most commonly causes upper respiratory tract infections, but it can also cause pneumonia, referred to as “walking pneumonia.” Although cavitary lesions are present in a wide variety of infectious and noninfectious processes, those attributable to M. pneumoniae are extremely uncommon; thus, to date, epidemiological studies are lacking. Here, we present a rare case of a 20-year-old male, referred to us from a psychiatric facility for evaluation of a cough, who was found to have a cavitary lesion in the right upper lobe. An extensive workup for cavitary lesion was negative, but his mycoplasma IgM level was high. A computed tomography (CT) of the chest confirmed the presence of a cavitary lesion. After treatment with levofloxacin antibiotics, a follow-up CT showed complete resolution of the lesion. Our case is a rare presentation of mycoplasma pneumonia as a cavitary lesion in a patient without any known risk factors predisposing to mycoplasma infection. Early recognition and treatment with an appropriate antibiotic may lead to complete resolution of the cavitary lesion. PMID:28912822

Patterns of ambulatory medical care utilization and rheumatologist consultation predating the diagnosis of systemic lupus erythematosus: a national population-based study.

To investigate the records of ambulatory medical care from patients predating the diagnosis of systemic lupus erythematosus (SLE) using nationwide, population-based claims data. The frequencies and costs of ambulatory medical care utilization in 337 newly-diagnosed SLE cases between 2004 and 2010, identified from Taiwan's National Health Insurance Research Database, were compared with 1,348 controls who were frequency matched for sex, age, and the catastrophic illness certificate application year of the cases. Patients with SLE had a median frequency of ambulatory medical care utilization compared with controls one year prior to the index date (22 vs. 2, P<0.001). The differences were significant throughout all eight annual periods. Similarly, the inflation-adjusted costs of ambulatory medical care utilization in patients with SLE increased annually over the study period, from a median of US$18 eight years prior to the index date to US$680 one year prior to the index date. Diseases of the respiratory system (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] codes 460-519), digestive system (ICD-9-CM codes 520-579), musculoskeletal system and connective tissue (ICD-9-CM codes 710-739, excluding 710.0), and skin and subcutaneous tissue (ICD-9-CM codes 680-709) were the top four common causes of visits in the 0.5 to 2 year period preceding the index date and percentages of SLE patients suffered from these disorders increased progressively over the study period. Only 56.4% of the patients with SLE had consulted a rheumatologist and most of the serology tests were done within one year predating the index date. Increased frequencies and costs of ambulatory care utilization among Taiwanese patients with SLE occurred several years predating their definitive SLE diagnosis. When multisystemic disorders are presented in young female patients, the possibility of SLE should be considered and screened with tools such as the antinuclear antibody test.

Phylogenies are usually dated by calibrating interior nodes against the fossil record. This relies on indirect methods that, in the worst case, misrepresent the fossil information. Here, we contrast such node dating with an approach that includes fossils along with the extant taxa in a Bayesian total-evidence analysis. As a test case, we focus on the early radiation of the Hymenoptera, mostly documented by poorly preserved impression fossils that are difficult to place phylogenetically. Specifically, we compare node dating using nine calibration points derived from the fossil record with total-evidence dating based on 343 morphological characters scored for 45 fossil (4--20 complete) and 68 extant taxa. In both cases we use molecular data from seven markers (∼5 kb) for the extant taxa. Because it is difficult to model speciation, extinction, sampling, and fossil preservation realistically, we develop a simple uniform prior for clock trees with fossils, and we use relaxed clock models to accommodate rate variation across the tree. Despite considerable uncertainty in the placement of most fossils, we find that they contribute significantly to the estimation of divergence times in the total-evidence analysis. In particular, the posterior distributions on divergence times are less sensitive to prior assumptions and tend to be more precise than in node dating. The total-evidence analysis also shows that four of the seven Hymenoptera calibration points used in node dating are likely to be based on erroneous or doubtful assumptions about the fossil placement. With respect to the early radiation of Hymenoptera, our results suggest that the crown group dates back to the Carboniferous, ∼309 Ma (95% interval: 291--347 Ma), and diversified into major extant lineages much earlier than previously thought, well before the Triassic.

Primary effusion lymphoma (PEL) or body cavity lymphoma is a rare type of extra nodal lymphoma of B-cell origin that presents as lymphomatous effusion(s) without any nodal enlargement or tumor masses. It belongs to the group of AIDS related non-Hodgkin's lymphomas. First described in 1996 in HIV infected individuals who were coinfected with Kaposi's sarcoma-associated herpesvirus (KSHV) or HHV-8 virus, it was included as a separate entity in WHO classification of tumors of hematopoietic and lymphoid tissue in the year 2001. The definition included association with HHV-8 virus as a mandatory diagnostic criterion. However, cases were later reported where PEL-like disease process was diagnosed in HHV-8 negative patients. This was eventually recognized as a rare but distinct entity termed as “HHV-8-unrelated PEL-like lymphoma”. Herein, we are reporting a case of an elderly patient who presented with a large pleuropericardial effusion and was eventually diagnosed with this entity. Till date, only around 50 cases of HHV-8-unrelated PEL-like lymphoma have been reported and our case being EBV, HIV, and Hepatitis C negative makes it very unique and rare occurrence. We are also presenting a review of relevant literature focused mainly on comparing outcomes in patients treated with and without chemotherapy. PMID:24716045

How many published cases of serious adverse events after yellow fever vaccination meet Brighton Collaboration diagnostic criteria?

To perform a systematic review of all serious adverse events (SAEs) after yellow fever vaccination and to assess them according to Brighton Collaboration criteria. Nine electronic databases were searched with the terms "yellow fever vaccine" and "adverse events" to 10 July 2013 (no language/date limits). Two reviewers independently assessed studies, entered data, and assessed cases with Brighton Collaboration criteria. One hundred and thirty-one cases met Brighton Collaboration criteria: 32 anaphylaxis, 41 neurologic (one death), 56 viscerotropic (24 deaths), and 2 both neurologic and viscerotropic criteria. All SAEs occurred following first yellow fever (YF) vaccination. Two additional cases which met Brighton Collaboration criteria were proven due to wild virus. An additional 345 cases were presented with insufficient detail to meet Brighton Collaboration criteria:173 neurological, 68 viscerotropic (24 deaths), 67 anaphylaxis, and 34 cases from a UK database and 3 from a Swiss database described as "serious adverse events" but not further classified into neurologic or viscerotropic. A further 253 cases were excluded as presenting insufficient data to be regarded as yellow fever vaccine (YFV) related SAEs. One hundred and thirty-one cases met Brighton Collaboration criteria for serious adverse events after yellow fever vaccination. Another 345 cases did not meet Brighton criteria and 253 were excluded as presenting insufficient data to be regarded as serious adverse events after YFV. There are likely to be cases in areas that are remote or with insufficient diagnostic resources that are neither correctly assessed nor not published. Copyright © 2013 Elsevier Ltd.

Isolated unilateral temporalis muscle hypertrophy in a child: a case report with literature review.

PubMed

Ranasinghe, Jagath C; Wickramasinghe, Chandani; Rodrigo, Ganganath

2018-02-19

Temporalis muscle hypertrophy is a rare entity of masticatory muscle hypertrophy. All types of masticatory muscle hypertrophies have been documented of which temporalis muscle hypertrophy is one. Temporalis muscle hypertrophy is most commonly bilateral and usually associated with other types of masticatory muscles hypertrophy such as masseter or pterygoid hypertrophy. However, isolated unilateral temporalis muscle hypertrophy is extremely rare and only 9 cases have been reported to date in English literature since 1990 with only two patients less than 18 years. There is no exact etiology identified and the diagnosis is made by muscle biopsy combined with imaging study to exclude other possibilities. Age at presentation is ranges from 15 to 65 years with involvement of both sexes. We report the youngest child who is a seven year old girl with right side isolated unilateral temporalis muscle hypertrophy. In this patient, we discuss the youngest child with isolated unilateral temporalis muscle hypertrophy and literature review to date. The patient is a seven year old female presenting with painless swelling of the right temporalis muscle. There had no features of inflammation, trauma, neoplasm or history of parafunctions such as bruxism. The child was not complaining significantly headache or visual disturbances as well. She had undergone radiological assessment with ultrasound scan and contrast MRI. The diagnosis was confirmed by muscle biopsy which shows normal muscle architecture. She was managed conservatively with regular follow up. Isolated unilateral temporalis muscle hypertrophy is extremely rare in children. However this case raises the importance of considering alternative diagnoses despite the condition being rare in the pediatric population.

Background: Clostridium perfringens gas gangrene is an extremely rare and fatal infection. Necrosis of the myometrium is rarely seen and has only been recorded in 18 cases to date. Of these 18 reported cases, only 5 have occurred in nonpregnant women. This article presents the 6th case of myometrium necrosis from C. perfringens. Case: A 72-year-old woman, gravida 2, para 2, presented with abdominal pain and vaginal bleeding. After examinations, laboratory testing, and several surgical interventions, she was found to have C. perfringens infection and advanced high-grade serous adenocarcinoma of the endometrium with >50% invasion into the myometrium. Results: Despite the surgical interventions and use of several antibiotics, this patient did not improve. She was weaned from treatment per her advance directive and died after weaning. Conclusions: Awareness of the many etiologies for peritonitis is of great importance when a fatal infection may be the cause of the condition. Correct diagnosis and proper treatment is essential for the survival of patients infected with C. perfringens . (J GYNECOL SURG 32:182).

Kirschsteiniothelia is a saprophytic fungus that is abundantly present in the environment. To date, there have been no reports of human infection caused by this fungus. We report a case of Kirschsteiniothelia infection superimposed on a pre-existing non-infectious bursitis of the ankle. An 81-year-old immunocompetent female local farmer noticed the presence of a nodule on her right ankle 5 years before her first visit to our hospital. A cystic mass of approximately 45 mm × 30 mm was present at the tip of the right lateral malleolus. Culture of the aspirated fluid revealed visibly black colonies and characteristic blackish hyphae; nucleotide sequence of the internal transcribed spacer region was determined and compared in a GenBank database. The results indicated Kirschsteiniothelia infection. We described the first case of Kirschsteiniothelia infection manifested as ankle bursitis. The disease seemed to be localized and systemic antibiotics had not been used in this case. However, continued observation is needed because of the possibility of disease progression with the pathogen.

The influence of taxon sampling on Bayesian divergence time inference under scenarios of rate heterogeneity among lineages.

PubMed

Soares, André E R; Schrago, Carlos G

2015-01-07

Although taxon sampling is commonly considered an important issue in phylogenetic inference, it is rarely considered in the Bayesian estimation of divergence times. In fact, the studies conducted to date have presented ambiguous results, and the relevance of taxon sampling for molecular dating remains unclear. In this study, we developed a series of simulations that, after six hundred Bayesian molecular dating analyses, allowed us to evaluate the impact of taxon sampling on chronological estimates under three scenarios of among-lineage rate heterogeneity. The first scenario allowed us to examine the influence of the number of terminals on the age estimates based on a strict molecular clock. The second scenario imposed an extreme example of lineage specific rate variation, and the third scenario permitted extensive rate variation distributed along the branches. We also analyzed empirical data on selected mitochondrial genomes of mammals. Our results showed that in the strict molecular-clock scenario (Case I), taxon sampling had a minor impact on the accuracy of the time estimates, although the precision of the estimates was greater with an increased number of terminals. The effect was similar in the scenario (Case III) based on rate variation distributed among the branches. Only under intensive rate variation among lineages (Case II) taxon sampling did result in biased estimates. The results of an empirical analysis corroborated the simulation findings. We demonstrate that taxonomic sampling affected divergence time inference but that its impact was significant if the rates deviated from those derived for the strict molecular clock. Increased taxon sampling improved the precision and accuracy of the divergence time estimates, but the impact on precision is more relevant. On average, biased estimates were obtained only if lineage rate variation was pronounced. Copyright © 2014 Elsevier Ltd. All rights reserved.

An automated procedure for developing hybrid computer simulations of turbofan engines

NASA Technical Reports Server (NTRS)

Szuch, J. R.; Krosel, S. M.

1980-01-01

A systematic, computer-aided, self-documenting methodology for developing hybrid computer simulations of turbofan engines is presented. The methodology makes use of a host program that can run on a large digital computer and a machine-dependent target (hybrid) program. The host program performs all of the calculations and date manipulations needed to transform user-supplied engine design information to a form suitable for the hybrid computer. The host program also trims the self contained engine model to match specified design point information. A test case is described and comparisons between hybrid simulation and specified engine performance data are presented.

Genotypic analysis of the earliest known prehistoric case of tuberculosis in Britain.

PubMed

Taylor, G Michael; Young, Douglas B; Mays, Simon A

2005-05-01

The earliest known case of human tuberculosis in Britain dates to the middle period of the Iron Age, approximately 2,200 years before present. Bone lesions on the spine of a male skeleton excavated at Tarrant Hinton in Dorset, United Kingdom, show evidence of Pott's disease and are supported by molecular evidence of Mycobacterium tuberculosis complex DNA amplified by IS6110 PCR (19). In the present study, we used a further series of sensitive PCR methods to confirm the diagnosis of tuberculosis and to determine the genotype of the infecting strain. These tests demonstrated that this individual was infected with a strain of M. tuberculosis rather than Mycobacterium bovis. The strain had undergone the tuberculosis D1 deletion affecting the mmpS6 and mmpL6 genes and can therefore be identified as a member of the family of "modern" M. tuberculosis isolates. All evidence obtained was consistent with surviving mycobacterial DNA being highly fragmented in this case.

Traumatic Pulmonary Herniation at the Diaphragmatic Junction in a Pediatric Patient: A Rare Complication of Blunt Chest Trauma.

2016-07-01

We present a case of traumatic intercostal pulmonary herniation in an 11-year-old boy after blunt trauma to the chest, without associated chest wall disruption or pneumothorax. This condition is especially uncommon in children, with only 5 previously reported cases and most occurring after penetrating chest trauma. To date, there are no reports in literature describing traumatic intercostal lung herniation at the diaphragmatic junction with a closed chest cavity in a child. The number of traumatic lung herniation diagnoses may be expanded by a more liberal use of computed tomography when serious injury is suspected. Computed tomography and advanced imaging should be considered in pediatric trauma patients presenting with concern for intrathoracic injury that may not be seen on plain film. Traumatic blunt intrathoracic and intra-abdominal injuries in the pediatric population that are within proximity of diaphragmatic insertion should be thoroughly evaluated to rule out diaphragmatic injury. As in our case, invasive surgical intervention such as thoracoscopy may be necessary.

Hand-arm vibration syndrome from exposure to high-pressure hoses.

Cooke, R; House, R; Lawson, I J; Pelmear, P L; Wills, M

2001-09-01

Hand-arm vibration syndrome has been reported in the literature to occur following exposure to vibration from the use of many tools, but to date there have been no case reports of its occurrence in workers who have used high-pressure hoses, alone or with other tools. To remedy this, the case histories of nine subjects (two without mixed exposure) examined in the UK and Canada are presented, together with their severity classified according to the Stockholm scales. Attention is drawn to the need to use multiple diagnostic tests to establish the diagnosis and the need to implement vibration isolation and damping methodologies, as and when feasible, with respect to hose nozzles in order to minimize the hazard. The ultimate goal for tool manufacturers, hygienists and engineers should be to reduce workplace vibration levels to meet national and international guidelines and legislation, including UK Health & Safety Executive guidelines and European Economic Community directives. The respective risk levels are presented, together with vibration measurements on hoses used by some of the cases.

Unexplained dyspnea in a patient of chronic arsenicosis: A diagnostic challenge and learning curve for physicians

2015-01-01

Chronic arsenic exposure causes cutaneous effects like hyperkeratosis, peripheral vascular disease, hypertension, ischemic heart disease, non-cirrhotic portal hypertension, hepatomegaly, peripheral neuropathy, respiratory involvement, bad obstetrical outcome, hematological disturbances, and diabetes mellitus. Here we present a case of a 24-year-old lady, with chronic exposure to arsenic, presenting to us with progressive dyspnea. We found pulmonary arterial hypertension (PAH) as a cause of her dyspnea. PAH can occur in arsenicosis, secondary to arsenic-induced chronic obstructive pulmonary disease (COPD), lung fibrosis, and portal hypertension, which we excluded by appropriate investigations in our case. We also excluded a familial or heritable form of PAH. Thus, with the exclusion of all these secondary causes of PAH, as well as a hereditary cause, we came to a conclusion that this PAH might be due to chronic arsenic exposure. To the best of our knowledge, no case of PAH in chronic arsenicosis has been reported to date. PMID:25814805

On October 29, 2012, Hurricane Sandy made landfall and devastated New York's metropolitan area, causing widespread damage to homes and the utility infrastructure. Eight days later, snow and freezing temperatures from a nor'easter storm delayed utility restoration. To examine carbon monoxide (CO) exposures in the 2 weeks following Hurricane Sandy. Methods. This was a retrospective review of prospectively collected, standardized, and de-identified data sets. CO exposures and poisonings identified from two electronic surveillance systems, the New York City Poison Control Center (NYCPCC) and New York City's Syndromic Surveillance Unit, were compared with CO exposures from identical dates in 2008-2011. Data collected from the poison center included exposure type, CO source, poisoning type, treatment, and outcomes. Data collected from the Syndromic Surveillance Unit cases, which were identified by CO-related chief complaints presenting to NYC hospitals, included visit date and time, and patient demographics. Four hundred thirty-seven CO exposures were reported to the NYCPCC, 355 from NYC callers, and the remainder from surrounding counties, which represented a significant increase when compared with CO exposures from identical dates in the preceding 4 years (p < 0.001). The total cases that were reported to the NYCPCC in 2008, 2009, 2010, and 2011 were 18, 13, 24, and 61, respectively. Excluding a single apartment fire that occurred (n = 311), the more common sources of CO were grilling indoors (26.2%) and generators (17.5%). Syndromic surveillance captured 70 cases; 6 cases were captured by both data sets. CO exposures following weather-related disasters are a significant public health concern, and the use of fuel-burning equipment is a clear source of storm-related morbidity and mortality. Multiple real-time epidemiologic surveillance tools are useful in estimating the prevalence of CO exposure and poisoning and are necessary to assist public health efforts to prevent CO poisoning during and after disasters.

Urban Growth Scenarios of a Future MEGA City: Case Study Ahmedabad

Lehner, A.; Kraus, V.; Steinnocher, K.

2016-06-01

The study of urban areas and their development focuses on cities, their physical and demographic expansion and the tensions and impacts that go along with urban growth. Especially in developing countries and emerging national economies like India, consistent and up to date information or other planning relevant data all too often is not available. With its Smart Cities Mission, the Indian government places great importance on the future developments of Indian urban areas and pays tribute to the large-scale rural to urban migration. The potentials of urban remote sensing and its contribution to urban planning are discussed and related to the Indian Smart Cities Mission. A case study is presented showing urban remote sensing based information products for the city of Ahmedabad. Resulting urban growth scenarios are presented, hotspots identified and future action alternatives proposed.

Being altered by the unexpected: understanding the perioperative patient's experience: a case study.

PubMed

Rudolfsson, Gudrun

2014-08-01

The present paper focuses on the process of understanding the patient in the context of perioperative caring and reports a story narrated by a perioperative nurse as well as her emerging understanding of the patient prior to surgery at an operating department. This qualitative case study had a dual purpose; firstly, to describe how the perioperative nurse's understanding of the patient emerged and, secondly, to establish how the researcher interpreted the situation. As a perioperative nurse and researcher, the author is both the narrator and interpreter. To date we have rarely discussed the fact that, in a perioperative context, the patient might feel ashamed of his/her body, even before arriving at the operating department. This new understanding emerged from the hermeneutical dialogue in the present study. © 2013 Wiley Publishing Asia Pty Ltd.

2013-01-01

Purpose Primary intraosseous haemangioma (IOH) is a rare benign neoplasm presenting in the fourth and fifth decades of life. The spine and skull are the most commonly involved, orbital involvement is extremely rare. We describe six patients with cranio-orbital IOH, the largest case series to date. Patients and methods Retrospective review of six patients with histologically confirmed primary IOH involving the orbit. Clinical characteristics, imaging features, approach to management, and histopathological findings are described. Results Five patients were male with a median age of 56. Pain and diplopia were the most common presenting features. A characteristic ‘honeycomb' pattern on CT imaging was demonstrated in three of the cases. Complete surgical excision was performed in all cases with presurgical embolisation carried out in one case. In all the cases, histological studies identified cavernous vascular spaces within the bony tissue. These channels were lined by single layer of cytologically normal endothelial cells. Discussion IOCH of the cranio-orbital region is rare; in the absence of typical imaging features, the differential diagnosis includes chondroma, chondrosarcoma, bony metastasis, and lymphoma. Surgical excision may be necessary to exclude more sinister pathology. Intraoperative haemorrhage can be severe and may be reduced by preoperative embolisation. PMID:23989119

Methicillin-sensitive Staphylococcus aureus (MSSA) meningitis is a rare disease when not related to neurosurgery: there are only few reported cases in the literature to date. We describe a case that highlights not only meningeal but also diffuse and rapidly progressive systemic involvement with multi-organ failure. A 64-year-old male presented to our hospital with a chief complaint of acute worsening of his usual chronic lower back pain, progressive weakness in lower extremities and subjective fevers at home. Hospital course demonstrated MSSA bacteremia, of questionable source, that resulted in endocarditis affecting right and left heart in a patient with no history of intravenous drug use. The case was complicated by septic emboli to systemic circulation involving the kidneys, vertebral spine, lungs and brain with consequent meningitis and stroke, even when treated empirically with vancomycin and then switched to nafcillin as indicated. Even though MSSA infections are well known, there are very few case reports describing such an acute-simultaneous-manifestation of multi-end-organ failure, including meningitis and stroke. Our case, also presented with an uncommon manifestation of persistent infection dissemination despite adequate antibiotic treatment.

Ramped PyrOx 14C With a Twist: Improving Radiocarbon Chronologies on Highly Detrital Marginal Antarctic Sediments

NASA Astrophysics Data System (ADS)

Subt, C.; Yoon, H.; Yoo, K. C.; Lee, J. I.; Domack, E. W.; Rosenheim, B. E.

2016-02-01

Highly detrital sediments can be difficult to date when the detritus includes material similar to that from which dates are sought. For radiocarbon dating, samples with a high degree of pre-aged detrital carbon contamination necessitate measurement of a very small portion of the sample to remove that contamination from the targeted component, even when using advanced techniques such as Ramped PyrOx (RP) 14C dating. Here we present three case studies of alternative RP approaches, producing accurate and precise chronologies for highly detrital sediments near the Larsen C ice shelf, near the Drygalski Ice Tongue in Ross Sea, and in Lapeyrère Bay, Anvers Island. For sediments where the proportion of organic carbon that was modern at the time of deposition is too small for a traditional AMS analysis after RP treatment, we have developed an innovative multiple RP analyses approach to minimize the cost in precision from using smaller temperature intervals, while maximizing the benefit in accuracy. Resulting sub ice-shelf chronologies show vastly improved dates down-core, significantly younger than the equivalent 14C chronology from the bulk acid insoluble organic (AIO) carbon with increasing ages down-core. By comparison, bulk AIO 14C dates in the study areas are not only older, but are subject to age reversals and nearly constant ages that make sedimentation rates impossible to resolve. Using our new approaches, we can reduce pre-aged carbon contamination in Lapeyrère Bay, and date sediments within layers of siliceous mud and ooze in the Ross Sea, and near the Larsen C ice shelf. Improved accuracy for 14C dates of highly detrital sediments can sometimes require the incorporation of a larger blank correction to account for multiple analyses, decreasing the precision. Application of this method refines ages of hard-to-date sediments, removing limits on what to include in a regional approach to chronicle ice shelf collapse.

To determine population-based estimates of medical costs attributable to venous thromboembolism (VTE) among patients currently or recently hospitalized for acute medical illness. Population-based cohort study conducted in Olmsted County, Minnesota. Using Rochester Epidemiology Project (REP) resources, we identified all Olmsted County residents with objectively diagnosed incident VTE during or within 92 days of hospitalization for acute medical illness over the 18-year period of 1988 to 2005 (n=286). One Olmsted County resident hospitalized for medical illness without VTE was matched to each case for event date (±1 year), duration of prior medical history, and active cancer status. Subjects were followed forward in REP provider-linked billing data for standardized, inflation-adjusted direct medical costs (excluding outpatient pharmaceutical costs) from 1 year before their respective event or index date to the earliest of death, emigration from Olmsted County, or December 31, 2011 (study end date). We censored follow-up such that each case and matched control had similar periods of observation. We used generalized linear modeling (controlling for age, sex, preexisting conditions, and costs 1 year before index) to predict costs for cases and controls. Adjusted mean predicted costs were 2.5-fold higher for cases ($62,838) than for controls ($24,464) (P<.001) from index to up to 5 years post index. Cost differences between cases and controls were greatest within the first 3 months after the event date (mean difference=$16,897) but costs remained significantly higher for cases compared with controls for up to 3 years. VTE during or after recent hospitalization for medical illness contributes a substantial economic burden.

Schizophrenia and organic brain syndrome with trisomy 8 (group-C trisomy 8 [47, XX, 8+]).

Sperber, M A

1975-02-01

A supernumerary autosomal syndrome in the C group of submetacentric autosomes has not yet been delineated phenotypically, although cases of an extra C-group autosome have been reported. Recent technical advances (fluorescence and Giemsa banding) now permit positive identification of each autosome. The present case reports the presence of schizophrenia and organic brain syndrome in association with trisomy 8. It is the sixth case of trisomy 8 reported to date. A stress-diathesis model is used to explain the development of the psychiatric disturbances. The patient's autosomal aberration is regarded as diathetic, and the multiple congenital anomalies, surgical interventions, infections, familial, and other environmental responses as stress. This report provides further data for the phenotypic delineation of a trisomy 8 syndrome.

Social media activities have gained popularity amongst children and adolescents as a means of communication; giving them the opportunity for independence and social development as well as rendering them vulnerable to negative influences. In traditionally collectivistic societies like India, moving rapidly towards modernisation, not only is there a divide between parents and adolescents over the endorsement of these sites, but also regarding value systems related to autonomy and dating that are facilitated by such activities. We present cases of two adolescent girls to highlight adolescent parent conflict that arises in the age of social media in a cultural context. Further, the cases underscore that value systems and culture play an important role in resolution of such conflict. Copyright © 2016. Published by Elsevier B.V.

Cholera cases cluster in time and space in Matlab, Bangladesh: implications for targeted preventive interventions.

: Cholera remains a serious public health threat in Asia, Africa and in parts of the Americas. Three World health Organization (WHO) pre-qualified oral cholera vaccines are now available but their supply is limited, so current supplies must be administered strategically. This requires an improved understanding of disease transmission and control strategies. : We used demographics and disease surveillance data collected from 1991 to 2000 in Matlab, Bangladesh, to estimate the spatial and temporal extent of the zone of increased risk around cholera cases. Specifically, we compare the cholera incidence among individuals living close to cholera cases with that among individuals living close to those without medically-attended cholera in this rural endemic setting. : Those living within 50 m of a confirmed cholera case had 36 times (95% confidence interval: 23-56) the risk of becoming a cholera case in the first 3 days (after case presentation) compared with risk elsewhere in the community. The relative risk gradually declined in space and time, but remained significantly high up to 450 me away within 3 days of case presentation, and up to 150 m away within 23 days from the date of presentation of the case. : These findings suggest that, if conducted rapidly, vaccinating individuals living close to a case (ring vaccination) could be an efficient and effective strategy to target vaccine to a high-risk population in an endemic setting. © The Author 2016; all rights reserved.

Yakoushina, Tatiana V.; Lavi, Ehud; Hoda, R. S.

2010-01-01

Pituitary carcinoma (PC) is a very rare entity (0.2% of all pituitary tumors), with only about 140 cases reported in English literature. There are no reliable histological, immunohistochemical or ultrastructural features distinguishing pituitary adenoma (PA) from PC. By definition, a diagnosis of PC is made after a patient with PA develops non-contiguous central nervous system (CNS) or systemic metastases. To date, only three cases of PC have been reportedly diagnosed on fine needle aspiration (FNA). Two of the reported cases were diagnosed on FNA of the cervical lymph nodes and one on FNA of the vertebral bone lesion. Herein, we present a case of PC, diagnosed on FNA of the liver lesion. In this case, we describe cytologic features of PC and compare them to histologic features of the tumor in the pituitary. Clinical behavior of tumor, pathogenesis of metastasis and immunochemical and prognostic markers will also be described. PMID:20806088

Angiocentric glioma is a rare tumor that was recognized by the WHO Classification of Tumours of the Central Nervous System as a distinct clinicopathological entity in 2007. Since this initial description, the vast majority of cases of angiocentric glioma reported in the literature have involved tumors of the cerebral hemispheres. To date, only 1 case of angiocentric glioma arising from the posterior midbrain has been reported. The authors present the cases of 2 pediatric patients who were found to have brainstem angiocentric gliomas. The clinical course, radiological and pathological features, treatment, and follow-up are described. The first case is one of a 5-year-old girl who presented with double vision, headache, and nausea and was found to have a midbrain lesion with pathological features consistent with angiocentric glioma. She was treated with resection and endoscopic third ventriculostomy (ETV), followed by close observation and serial neuroimaging. The second case is one of a 6-year-old boy who presented with progressive mouth drooping and problems with balance. He was found to have a pontine lesion with pathological features consistent with angiocentric glioma. This patient was treated with ETV, followed by close observation and serial neuroimaging. This report includes 6 and 1.5 years of follow-up of the patients, respectively. While there are limited data regarding the prognosis or long-term management of patients with brainstem angiocentric gliomas, the cases described in this report suggest an indolent course for this tumor, similar to the course of angiocentric gliomas located in the cerebral hemispheres.

On 4th February 2015, a group of Senior High School students from Fanteakwa district presented to the emergency unit of the district hospital with complaints of abdominal pain, vomiting and diarrhoea. All the students had eaten from a specific food vendor and had neither eaten any other common meal that day nor the previous day. A foodborne disease outbreak was suspected. We investigated to verify the outbreak, determine its magnitude, identify the source and implement control measures. A retrospective cohort study was conducted. We reviewed medical records and interviewed patrons of the food vendor. We collected data on age, sex, signs and symptoms, date of illness onset, date of admission, date of discharge, treatments given and outcome. A case of foodborne disease was any person in the school with abdominal pain, vomiting and or diarrhoea from 4th to 11th February 2015 and had eaten from the food vendor. We conducted active case search to identify more cases. We conducted environmental assessment and collected clinical and food samples for laboratory testing. Descriptive and inferential statistical analyses were performed using Stata 12.0. A total of 68 cases were recorded giving overall attack rate of 35.79 % (68/190) with no death. Of these, 51.47 % (35/68) were males. Mean age of case-patients was 17.8 (standard deviation +/-1.62). The index case, a 17-year-old female student ate from the food vendor on 4th February at 9:00 am and fell ill at 3:40 pm later that day. Compared to those who ate other food items, students who drank water from container at the canteen were more likely to develop foodborne disease at statistically significant levels [RR = 2.6, 95 % CI = (2.11-3.15)]. Clostridium perfringens (C. perfringens) and Salmonella species (Salmonella spp) were isolated from water and stew respectively. Clinical features of case-patients were compatible with both organisms. A foodborne gastroenteritis outbreak occurred in a Senior High School in Fanteakwa District from 4th to 7th February 2015. The most probable aetiologic agent was C. perfringens with contaminated water at canteen as the vehicle of transmission. Concurrent Salmonella spp infection could not be ruled out. Rapid outbreak response helped in controlling the outbreak.

Atypical coastal environmental change during Copper Age - Bronze Age transition (Rio de Moinhos, NW Portugal) - preliminary results

NASA Astrophysics Data System (ADS)

Granja, Helena; Danielsen, Randi

2015-04-01

The research is part of an ongoing project of geo-archaeology from Rio de Moinhos beach (Esposende, NW Portugal), where an extensive area of dark sedimentary outcrops and a large amount of ceramic remains from a Roman shipwreck are present. The dark sedimentary deposit, presenting tree stumps and roots in life position, partially covers a rocky platform that extends seawards. Over the platform, that presents many pits of sea urchins (infralittoral environment) as well as salt pans (supratidal environment), a marine rusty conglomerate is present in some places. Several hand gauge cores were extracted in the sedimentary deposit whose maximum depth do not exceed 50cm. Samples from cores and outcrops were analysed for grain size, mineralogical composition, pollen and diatom content and radiocarbon dated. This work concerns sediment size analysis, dating and pollen. Tree stumps and roots of Alnus glutinosa dated 6310-6220 cal BP are in the base of the sedimentary sequence that presents a gradual passage from very fine sands to clayey silts, all of them organic and very poorly sorted. Pollen analysis revealed an initial wetland habitat containing Alnus, inundated ca 5645-5585 cal BP due to rising sea level at the time. A brackish lagoon formed at the site presumably protected by a clastic barrier seaward. Similar formations of lagoons are detected all along the Portuguese coast, typically disappearing with time due to sand infilling. In this case, however, the brackish lagoon turned into a fresh water lake ca 4485-4440 cal BP. This may have been a natural development caused by permanent closing of the clastic barrier but human interference cannot be excluded as anthropic activity was detected since formation of the lagoon. The lake seems to have filled in with sand at some point in time subsequent to ca 3750-3725 cal BP, the date of the top lake sediment. However, shipwreck vestiges from the Roman Period presently dispersed over the lake sediment, suggests a later date for its infilling. Furthermore dating of wooden remains of what was interpreted as a fish trap, found on the sediment surface gave the age 2055-1770 cal BP (Roman Period). The old age of the top level may hence be the result of truncation of the sediment sequence at least in parts of the platform. Landwards, the Roman period is represented by fine and dark sediments similar to those of Rio de Moinhos beach, found in deeper cores. Acknowledgments This research is included in the project PTDC/EPH-ARQ/5204/2012 supported by FCT (Foundation for Science and Technology, Portugal).

Identification of abnormalities in the developmental trajectory during infancy of future schizophrenia cases offers the potential to reveal pathogenic mechanisms of this disorder. Previous studies of head circumference in pre-schizophrenia were limited to measures at birth. The use of growth acceleration of head circumference (defined as the rate of change in head circumference) provides a more informative representation of the maturational landscape of this measure compared to studies based on static head circumference measures. To date, however, no study has examined whether HC growth acceleration differs between pre-schizophrenia cases and controls. In the present study, we employed a nested case control design of a national birth cohort in Finland. Cases with schizophrenia or schizoaffective disorder (N=375) and controls (N=375) drawn from the birth cohort were matched 1:1 on date of birth (within 1month), sex, and residence in Finland at case diagnosis. Longitudinal data were obtained on head circumference from birth through age 1. Data were analyzed using a new nonparametric Bayesian inversion method which allows for a detailed understanding of growth dynamics. Adjusting for growth velocity of height and weight, and gestational age, there was significantly accelerated growth of head circumference in females with schizophrenia from birth to 2months; the findings remained significant following Bonferroni correction (p<0.0125). This is the first study to report abnormal HC growth acceleration, a more sensitive measure of somatic developmental deviation of this measure, in schizophrenia. Copyright © 2016 Elsevier B.V.

Brazil has experienced an unprecedented epidemic of Zika virus (ZIKV), with ~30,000 cases reported to date. ZIKV was first detected in Brazil in May 2015, and cases of microcephaly potentially associated with ZIKV infection were identified in November 2015. We performed next-generation sequencing to generate seven Brazilian ZIKV genomes sampled from four self-limited cases, one blood donor, one fatal adult case, and one newborn with microcephaly and congenital malformations. Results of phylogenetic and molecular clock analyses show a single introduction of ZIKV into the Americas, which we estimated to have occurred between May and December 2013, more than 12 months before the detection of ZIKV in Brazil. The estimated date of origin coincides with an increase in air passengers to Brazil from ZIKV-endemic areas, as well as with reported outbreaks in the Pacific Islands. ZIKV genomes from Brazil are phylogenetically interspersed with those from other South American and Caribbean countries. Mapping mutations onto existing structural models revealed the context of viral amino acid changes present in the outbreak lineage; however, no shared amino acid changes were found among the three currently available virus genomes from microcephaly cases. Municipality-level incidence data indicate that reports of suspected microcephaly in Brazil best correlate with ZIKV incidence around week 17 of pregnancy, although this correlation does not demonstrate causation. Our genetic description and analysis of ZIKV isolates in Brazil provide a baseline for future studies of the evolution and molecular epidemiology of this emerging virus in the Americas.

In this study, Electron Spin Resonance (ESR) spectroscopy is used to determine the geological ages of fossil mollusc shells systematically collected from two different geological splitting at İsmil Location (37.72769° N, 33.17781° E) in eastern part of Konya. According to the assessment of obtained ESR ages, the importance of pre-annealing treatment emphasize in the case of g=2.0007 dating signal is overlapped with the other signals arisen from short lived radicals that cause the wrong age calculation. To overcome this problem, the samples are pre-annealed at 180°C for 16 minutes and, in this case ESR ages are re-calculated for g=1.9973 dating signal. Dose response curves are obtained using 1.9973 signals after pre-annealing treatments for each samples. ESR ages of samples are obtained in the range of 138 ± 38 ka and 132 ± 30 ka (Upper Pleistocene) according to the Early Uranium Uptake model and the results are in good agreement with the estimated ages from stratigraphic and paleontological correlation by geologists. Thus, it is suggested that especially in the case of 2.0007 dating signal cannot been used due to superimposition case, the signal with 1.9973 g value can be used for dating after pre-annealing treatment. The results reports the first ESR ages on shells collected from İsmil Location and highlight the importance of pre-annealing treatment. This study is supported by TUBITAK 114Y237 research project.

Dating of Modern Human Evolution

NASA Astrophysics Data System (ADS)

Grun, R.

Dating studies on palaoeanthropological sites is usually carried out on material associ- ated with the human remains, such as the sediment, charcoal or other fauna rather than the human specimen itself. The reason lies in the fact that most dating techniques are destructive and because the hominid remains are too rare to be sacrificed for dating. This indirect dating approach is in many cases not satisfactory, because: (i) the human remains are often buried into the sediments and the association with other materials is uncertain (e.g. Skhul, Qafzeh, etc.); (ii) faunal remains or minerals from the sediment are re-worked from older deposits (see e.g. present discussion of the age of the Homo erectus remains in Indonesia; (iii) the hominid fossils were discovered at a time when no careful excavations were carried out and it is impossible to correlate the specimen with other datable material (which applies tonearly 90% of all palaeoanthropological specimens). For example, the hominid burial site of Qafzeh in Israel has been dated by several independent dating laboratories with a multitude of methods. However, the data are still not accepted by some because the dating has not been carried out on the hominid specimen. Until recently, hominid fossils could only be dated by radiocarbon. This method reaches back to about 40,000 years. As a consequence, all the older fossils could not be analysed and many important questions in our understanding of human evolution could not be addressed. Human remains are scarce and extremely valuable, therefore any sort of destruction has to be kept to an absolute minimum. This is of particular importance in Australia where any human fossils are sacred. Thus, for the analysis of hominid material it was necessary to develop a more or less non-destructive techniques. This has been ac- complished in recent years by the application of ESR dating of tooth enamel and a combination of gamma spectrometric and TIMS U-series dating of bones. The exam- ples of Florisbad, Mungo 3, Shkul and Tabun are used to illustrate the potential and pitfalls of these methods in palaeoanthropology.

2007-01-01

Background Documentation of superfoetation is extremely rare in humans., The younger foetus has invariably been small for gestational age (estimated from the date of the last menstrual bleed) in all the cases reported in the literature. We report a case where the younger twin was of appropriate size for gestation. Case Presentation The first of twins was of 32 weeks gestation and the baby was of appropriate size and development for the gestational age. The second twin was of 36 weeks gestation. Gestational age was estimated with the New Ballard score, x-ray of the lower limbs, dental age on x-ray, and ophthalmic examination. Conclusion Bleeding on implantation of the first foetus probably helped demarcate the two pregnancies. Dental age and the New Ballard score can be used to diagnose superfoetation in discordant twins, when detailed first trimester ultra-sound data is not available. PMID:17239246

A rare case of giant occipital meningocele with Dandy Walker Syndrome: Can it grow bigger than this?

2016-01-01

Association of Dandy–Walker syndrome with occipital meningocele (OMC) is extremely rare and about thirty cases are reported till date in the Western literature. However, OMC is classified by Talamonti et al. into small, large, and giant categories with respective diameters were upto 5 cm in small, large with 5–9 cm, and giant with >9 cm. Usually the size of OMC progressively increases as raised intracranial pressure leads to compensatory cerebrospinal fluid escape into sac with the growth of children. Authors report an interesting case of an 18-month-old female child with extra-gigantic OMC, whose size was almost same since birth, representing the first case of its kind, who underwent successful surgical repair. Clinical presentation, radiological features, and surgical management options in literature are reviewed briefly for this rare disease association. PMID:28217162

Methods for the identification and selection of patients (cases) with severe or very severe pneumonia and controls for the Pneumonia Etiology Research for Child Health (PERCH) project were needed. Issues considered include eligibility criteria and sampling strategies, whether to enroll hospital or community controls, whether to exclude controls with upper respiratory tract infection (URTI) or nonsevere pneumonia, and matching criteria, among others. PERCH ultimately decided to enroll community controls and an additional human immunodeficiency virus (HIV)-infected control group at high HIV-prevalence sites matched on age and enrollment date of cases; controls with symptoms of URTI or nonsevere pneumonia will not be excluded. Systematic sampling of cases (when necessary) and random sampling of controls will be implemented. For each issue, we present the options that were considered, the advantages and disadvantages of each, the rationale for the methods selected for PERCH, and remaining implications and limitations.

Guillain-Barré syndrome presenting with Raynaud's phenomenon: a case report.

PubMed

Gunatilake, Sonali Sihindi Chapa; Wimalaratna, Harith

2014-09-03

Guillain-Barré syndrome is an immune mediated acute inflammatory polyradiculo-neuropathy involving the peripheral nervous system. Commonest presentation is acute or subacute flaccid ascending paralysis of limbs. Rarely autonomic dysfunction can be the presenting feature of Guillain-Barré syndrome. Raynaud's phenomenon, although had been described in relation to many disease conditions, has not been described in association with Guillain-Barré syndrome up to date. We report the first case of Guillain-Barré syndrome presenting with Raynaud's phenomenon in a 21-year-old previously well boy. New onset Raynaud's phenomenon was experienced followed by acute ascending flaccid paralysis of lower limbs and upper limbs together with palpitations and postural giddiness. Nerve conduction studies showed acute inflammatory demyelinating polyneuropathy with cerebrospinal fluid cyto-protein dissociation. He was treated with intravenous immunoglobulin and showed a satisfactory clinical recovery of muscle weakness, Raynaud's phenomenon and autonomic disturbances. Guillain-Barré syndrome presenting with Raynaud's phenomenon is not being reported in literature previously. Although the underlying mechanism is not fully understood, Raynaud's phenomenon should prompt the physician to consider Guillain-Barré syndrome with a complimentary clinical picture.

A multi-country outbreak of Mycobacterium chimaera infection associated with contaminated heater–cooler devices (HCDs) has been reported, with more than 70 cases in Europe and the United States and two cases in Canada to date. The epidemiological and microbiological characteristics of this outbreak provide evidence for common-source transmission of M. chimaera from the exhaust air of intrinsically contaminated HCDs to patients during cardiac surgery. To date, all reported cases have been associated with Stöckert 3T HCDs manufactured at one plant by LivaNova prior to September 2014. Implantation of prosthetic material increases the risk of infection. Infections usually present as prosthetic valve endocarditis, vascular graft infection or disseminated infection. Reported mortality rates have varied, but were often over 40%. Several measures are recommended to facilitate case-finding and mitigate risk of exposure. The feasibility of some risk mitigation measures and their effectiveness in reducing the risk of exposure are yet to be determined. Until HCDs are redesigned in a manner that prevents water contamination and aerosolization, separating the HCD exhaust air from the operating room air during surgery may be the most effective risk mitigation strategy. However, possible unintended consequences of this approach should be considered. This overview summarizes findings from peer-reviewed and other relevant national documents on key features of the outbreak, including the source, identified risk factors for infection, signs and symptoms of infection, burden of disease, risk mitigation measures, management challenges and knowledge gaps.

2017-01-01

Background Oral submucous fibrosis (OSF) is an insidious chronic condition characterized by restricted mouth opening. Prosthetic rehabilitation is challenging for OSF patients as obtaining a good impression requires adequate mouth opening. The aim of the present review is to systematically present the data from case reports published in the English-language literature. Method A comprehensive search of the literature databases (PubMed, Medline, SCOPUS, Web of Science and Google Scholar) along with the references of published articles on prosthetic rehabilitation in OSF patients published to date was conducted. Keywords included a combination of ‘Oral submucous fibrosis’, ‘prosthesis’, ‘dentures’ and/or ‘restricted mouth opening’. Citations from selected references and bibliographic linkages taken from similar cases were included in this review. The inclusion criteria selected for case reports on prosthetic rehabilitation in OSF patients, and cases of restricted mouth opening due to causes other than OSF were excluded from the study. Results A total of 21 cases were identified and analysed from 17 papers published in the English-language literature. Of these, 9 cases employed the sectional denture technique, 4 cases emphasized the need-based treatment approach in which conventional methods were modified, and 4 cases used mouth exercising devices. Finally, 1 case each involved, flexible denture, oral screen prosthesis, oral stents, surgery in conjunction with dentures. Conclusion Prosthetic rehabilitation in OSF patients is a multifaceted approach and should be patient specific, although sectional dentures have achieved the best results. PMID:28877246

To study the doping substances used in sport and their toxicity. Retrospective analysis from January 1992 to December 2000 of the cases of use of doping substances in sport reported by telephone to the anti-poison center in Marseilles. Fifty-one cases were reported concerning 48 men and 3 women with a mean age of 30, ranging from 10 to 55 years. Sixty-three percent of cases were reported over the last four years. The sport practiced was bodybuilding, except in 2 cases (cycling in one case and running in the other). The products used were mainly anabolizing hormones (15 times), clenbuterol (14 times) and creatine (7 times). A third of cases concerned associations of substances and 19 cases presented with symptomatology. The diversity in nature and status of the substances mentioned and their association requires enhanced vigilance with regard to the use of drugs in sport. The recent measures voted within the framework of the anti-doping law dated 23/3/99 are aimed at increasing surveillance with the development of anti-doping antennae.

Dendrochronologically dated pine stumps document phase-wise bog expansion at a northwest German site between ca. 6700 and ca. 3400 BC

The investigated northwest German mire site at Totes Moor is densely covered with subfossil pine stumps (Pinus sylvestris L.) from the fen-bog transition. This facilitates the spatio-temporal reconstruction of mire development, which is based on 212 in situ tree stumps in the case study presented here. Six dendrochronologically dated site chronologies together cover 2345 years between 6703 and 3403 BC. The gaps in between are 6 to 550 years long. Additionally, a floating chronology of 309 years, containing 30 trees, was radiocarbon-dated to the beginning of the 7th millennium cal BC. Peat-stratigraphical survey was carried out additionally, and elevations a.s.l. were determined at several locations. Tree dying-off phases, which indicate water level rise at the site, mostly in context of the local fen-bog transition, are evident for ca. 6600-6450, ca. 6350-5750, ca. 5300-4900, ca. 4700-4550, ca. 3900-3850, ca. 3700-3600, ca. 3500-3450 and ca. 3400 BC. The spatial distribution of the dated in situ trees illustrates the phase-wise expansion of raised bog over fen peat at the site. The documented bog expansion pulses likely correspond to climatic wet sifts.

Year of birth determination using radiocarbon dating of dental enamel

Radiocarbon dating is typically an archaeological tool rather than a forensic one. Recently however, we have shown that the amount of radiocarbon present in tooth enamel, as a result of nuclear bomb testing during the cold war, is a remarkably accurate indicator of when a person is born. Enamel isolated from human teeth is processed to form graphite and carbon-14 (14C) levels are measured using accelerator mass spectrometry. Since there is no turnover of enamel after it is formed, 14C levels in the enamel represent 14C levels in the atmosphere at the time of its formation. In this paper we describe the strategy used to determine the date of birth of an individual based on radiocarbon levels in tooth enamel, focusing on the methodology of this strategy. Year of birth information can significantly assist police investigators when the identity of a deceased individual is unknown. In such cases police will try to match particulars of the unidentified individual (which is often only gender and/or an estimate of age), with particulars from missing persons lists. PMID:20976120

2010-08-01

We examined birth-related malpractice civil litigation cases in Japan to clarify the actual status related to the implementation of an obstetrical no-fault compensation system in 2009. In this retrospective review, we analyzed legal and medical information from 64 cases with a delivery date after 1987 and a judgment date between April 1997 and March 2007. The malpractice claim was accepted in 44 cases and rejected in 20 cases. The period from the delivery to the judgment date was lengthy (90.1 months overall). The average amount of damages awarded was yen97 810,000 for cases of cerebral palsy (CP). Preterm births and less than 2500 g infants represented a higher incidence rate in the rejected cases. There were 32 cases (50.0%) with CP, 18 (28.1%) with infant death, 10 (15.6%) with neonatal death, and 4 (6.3%) with fetal death. Twenty-three of 44 accepted cases (52.3%) and 11/20 rejected cases (55.0%) had a gestational age of more than 33 weeks at birth and weighed more than 2000 g. Forced deliveries were performed in 45/64 cases (70.3%), and augmentation/induction of labor was performed in 28/64 cases (43.8%). There were 13/16 (81.3%) accepted cases that underwent vacuum and/or forceps extraction after labor augmentation/induction. More than half of our cases could be sufficient for a no-fault compensation system in Japan. Though the system is considered to have some problems that need to be solved, this finding suggests that many children and their families may benefit from the new system without having to file.

To report a case series of ischemic gastritis and discuss its etiology, management, and associated mortality according to our results and the published English literature. Ischemic gastritis is rare, given the rich blood supply of the stomach. It has been reported in isolated case reports and small case series. Most cases are vascular in origin and associated with a high mortality. Pathology databases from 3 hospitals affiliated with the University of Minnesota Medical School were searched for cases of ischemic gastritis in the last 10 years. Patients' demographics, clinical course, and 1-month and 1-year mortalities were collected from electronic medical records. A total of 12 patients were identified (age range, 32.1 to 83.2), the largest series reported to date. The presenting symptom was gastrointestinal bleeding (8), abdominal pain (2), nausea (1), and symptomatic anemia (1). The etiology included postinterventional radiology embolization (2), hemodynamic changes in the setting of celiac axis stenosis (2), vasculitis (1), systemic hypotension (1), and unknown (6). Treatment included steroid therapy, revascularization by interventional radiology, surgery, or supportive treatment. Thirty-day and 1-year mortalities were 33% and 41%, respectively. Ischemic gastritis is rare, but associated with a high mortality. Evaluation for treatable etiologies should be sought and corrected if present.

To report 2 cases of nonoperable intracranial bleeding associated with apixaban managed by 3-factor prothrombin complex concentrate (PCC3). Case 1 presented with a 1.3-cm left parieto-occipital hemorrhage and a thin subdural hematoma (SDH) on the left tentorium of the brain about 6 hours after his last dose of apixaban. Case 2 presented with a 4-mm left parafalcine SDH with time of most recent apixaban dose unknown. The patients received 24.9 to 25.5 U/kg of PCC3 with none to 1 U fresh frozen plasma (FFP) and demonstrated minimal or no progression in lesions measured by repeat computed tomography (CT) after treatment. One patient was discharged to a skilled nursing facility after 8 days; the other patient was discharged to home after 18 days. Apixaban has no specific antidote. Current bleeding management strategies are based on expert opinion. The risks and benefits for differing strategies are unclear, and little clinical experience for managing apixaban-associated intracranial bleeding has been reported to date. These cases describe the clinical use of PCC3 to manage parieto-occipital and subdural hemorrhage associated with apixaban in events not requiring surgical intervention. In these 2 cases, 25 U/kg PCC3, with none to one unit FFP, ceased apixaban-associated intracranial bleeding without apparent thrombogenic complications.

Growth hormone abuse and bodybuilding as aetiological factors in the development of bilateral internal laryngocoeles. A case report.

Moor, James W; Khan, M Iqbal J

2005-07-01

A 36-year-old man presented with hoarseness and stridor. He was an elite professional bodybuilder and admitted to having abusing anabolic steroids and growth hormone in the recent past. A CT scan showed bilateral laryngocoeles. The patient was initially managed with intravenous corticosteroids and broad-spectrum antibiotics, and the stridor resolved sufficiently to permit discharge from the hospital. He proceeded to undergo endoscopic marsupialisation of his laryngocoeles and to date has made a full recovery. This is the first reported case where anabolic steroid and growth hormone abuse combined with an elite bodybuilder's exercise regime has been implicated in the aetiology of bilateral laryngocoeles.

Goldmann, Stefan

2011-01-01

Starting from a passage in the Dora case history where Freud suggests some differences between a literary and a clinical narrative of female homosexuality, this paper presents examples which he might have had in mind. Besides Balzac's "La fille aux yeux d'or" (1834/35) it is in particular Alfred v. Berger's novella "Die Italienerin [The Italian woman]" (1904) which may have served as a model and counterpoint to the literary strategies used in Freud's case history. Freud had a relationship of long standing with Berger. This newly discovered source may provide a clue for the date at which Freud finalized the Dora manscript which he had held back for years.

Case reports of 16 crashes involving pregnant occupants are presented that illustrate the main conclusions of a crash-investigation program that includes 42 crashes investigated to date. Some unusual cases that are exceptions to the overall trends are also described. The study indicates a strong association between adverse fetal outcome and both crash severity and maternal injury. Proper restraint use, with and without airbag deployment, generally leads to acceptable fetal outcomes in lower severity crashes, while it does not affect fetal outcome in high-severity crashes. Compared to properly restrained pregnant occupants, improperly restrained occupants have a higher risk of adverse fetal outcome in lower severity crashes, which comprise the majority of all motor-vehicle collisions.

Intravascular papillary endothelial hyperplasia is a benign vascular lesion caused by proliferation of endothelium. It is reactive to thrombotic or inflammatory stimuli in the vessel wall.We report the case of a 14-yearold male patient with a violet-colored erythematous tumoral lesion of progressive growth in the occipital region. The diagnosis of intravascular papillary endothelial hyperplasia (IPEH) was confirmed by clinical and histopathological findings. Total lesion exeresis was performed with no recurrence up to date. IPEH presents clinical importance due to its clinical and histological resemblance to angiosarcoma. In order to differentiate it from angiosarcoma, distinguishing features of the benign disease should be considered, such as lack of cellular atypia and rare mitotic activity.Prognosis is good.

Head salvage of an infected neck of femur fracture in an adult: a case report.

PubMed

Joseph, Christina Marie; Jepegnanam, Thilak Samuel

2018-05-23

Head preservation of an infected neck of femur fracture appears to be extremely rare with no described cases in literature till date. We present the outcome of head salvage in a young adult with an infected neck of femur nonunion who in addition had chronic osteomyelitic sequelae of his entire femur with reactivation of latent infection in the distal femoral diaphysis. Osteosynthesis was performed by means of cancellous screw fixation augmented with bone substitute following a failed attempt at salvage with a valgus intertrochanteric osteotomy. The patient had an excellent functional outcome with near normal hip range of movements at a follow-up of 5 years after union.

The authors have drawn attention to a rare disease called infant botulism, which raises some difficulties with regard to differential diagnosis. In the case of the six-month-old infant portrayed, infant botulism and food-born botulism appeared together. As a result of the severity of the disease and due to its rapid course observed in the presented case as well, the diagnosis has to be raised relying on the accurate patient's history and on the clinical examination, then it should be confirmed by appropriate examinations. In relation to presenting a case, the authors examine the microbiological background of the disease, its symptomatology, its epidemiological characteristics, the appropriate methods of electrophysiological examination and laboratory analysis as recommended in current literature, together with the difficulties that arise in differential diagnosis and also the possibilities of treatment. They pay special attention to the particular characteristics of the infant form of the disease, to the difficulties of making a diagnosis due to the characteristics of the age group and also to the questions in relation to the guiding principles of therapy. The rapid and fatal process observed in the presented case warns us that serious complications can occur even when up-to-date therapy is used. Therefore, despite the improvement in prognosis we have to strive to prevent the disease by spreading the proper regulations of nutritional hygiene.

Epidemiologic data on phocomelia are scarce. This study presents an epidemiologic analysis of the largest series of phocomelia cases known to date. Data were provided by 19 birth defect surveillance programs, all members of the International Clearinghouse for Birth Defects Surveillance and Research. Depending on the program, data corresponded to a period from 1968 through 2006. A total of 22,740,933 live births, stillbirths and, for some programs, elective terminations of pregnancy for fetal anomaly (ETOPFA) were monitored. After a detailed review of clinical data, only true phocomelia cases were included. Descriptive data are presented and additional analyses compared isolated cases with those with multiple congenital anomalies (MCA), excluding syndromes. We also briefly compared congenital anomalies associated with nonsyndromic phocomelia with those presented with amelia, another rare severe congenital limb defect. A total of 141 phocomelia cases registered gave an overall total prevalence of 0.62 per 100,000 births (95% confidence interval: 0.52-0.73). Three programs (Australia Victoria, South America ECLAMC, Italy North East) had significantly different prevalence estimates. Most cases (53.2%) had isolated phocomelia, while 9.9% had syndromes. Most nonsyndromic cases were monomelic (55.9%), with an excess of left (64.9%) and upper limb (64.9%) involvement. Most nonsyndromic cases (66.9%) were live births; most isolated cases (57.9%) weighed more than 2,499 g; most MCA (60.7%) weighed less than 2,500 g, and were more likely stillbirths (30.8%) or ETOPFA (15.4%) than isolated cases. The most common associated defects were musculoskeletal, cardiac, and intestinal. Epidemiological differences between phocomelia and amelia highlighted possible differences in their causes.

Gold, Jessica A; Sher, Yelizaveta; Maldonado, José R

2016-01-01

Frontal lobe epilepsy (FLE) can masquerade as a primary psychiatric condition, be misdiagnosed in-lieu of a true psychiatric disorder, or may be comorbid with psychiatric illness. To (1) qualitatively review psychiatric manifestations of FLE and (2) to systematically review the cases/case series of psychiatric manifestations of FLE presented in the literature to date. A systematic review of the literature was performed following the PRISMA guidelines and using PubMed/Medline, PsychInfo, and Cochrane database of systematic reviews to identify cases and case series of psychiatric manifestations of FLE. A total of 35 separate articles were identified. Further, 17 patients primarily presented with psychosis, 33 with affective symptoms, and 16 with personality changes. Also, 62% of cases were males and 38% were females. Ages ranged from 2-83 years with the average age of 32.7. Prior psychiatric history was reported in 27.3% of cases. Causes of seizure were known in 53%, with the most common causes being dysplasia and tumor. Only 6 cases (<10%) did not have electroencephalographic correlations. Psychiatric manifestations were primarily ictal in 74.3% of the cases. Associated manifestations included motor (63.6%), cognitive (34.8%), and medical (9.0%) findings. Surgery was required in 31.8% of the cases, whereas others were treated with medications alone. All, but 3, patients were seizure free and saw an improvement in symptoms with treatment. Given the complexity and multifunctionality of the frontal lobes, FLE can present with complex, psychiatric manifestations, with associated motor, cognitive, and medical changes; thus, psychiatrists should keep FLE on the differential diagnosis of complex neuropsychiatric cases.

Zdanowicz, Martin M; Lynch, Launa M J

2011-09-10

To provide doctor of pharmacy (PharmD) students with highly integrated, comprehensive and up-to-date instruction related to the pharmacology of antiarrhythmic drugs. Students were taught the medicinal chemistry, pharmacology, and therapeutics of antiarrhythmic agents in the cardiology module presented in quarter 7 of the PharmD curriculum. Important foundational information for this topic was presented to students in prerequisite physiology courses and pathophysiology courses offered earlier in the curriculum. Emphasis was placed on student critical thinking and active involvement. Weekly recitation sessions afforded students the opportunity to apply the information they learned regarding arrhythmia pharmacotherapy to comprehensive patient cases. Student comprehension was measured using class exercises, short quizzes, case write-ups, comprehensive examinations, group exercises, and classroom discussion. Students were afforded the opportunity to evaluate the course, and the instructors as well as rate the degree to which the course achieved its educational outcomes. Students learned about cardiac arrhythmias through a high-quality, interdisciplinary series of classes presented by faculty members with extensive experience related to the pharmacology and pharmacotherapy of cardiac arrhythmias.

Dorsally exophytic glioblastoma arising from the medulla oblongata in an adult presenting as 4th ventricular mass.

Brainstem gliomas are relatively rare in adults (<2% of all gliomas). Exophytic gliomas are focal brainstem lesions, which project into the 4 th ventricle or cerebellopontine angles. These exophytic lesions are usually of low-grade histology (pilocytic astrocytoma or ganglioglioma) and have a relatively better outcome compared with brainstem gliomas as a whole. Glioblastoma is the commonest primary glial cell neoplasm and mostly occurs in the supratentorial compartment. It is rather uncommon in the brainstem and seldom has been described as having an exophytic growth pattern. Here we describe an exophytic brainstem glioblastoma arising from the medulla oblongata in a 55-year-old lady who presented with a 4 th ventricular mass, and present a brief review of the literature. Till now, six cases of glioblastoma arising from the medulla oblongata have been reported. So, ours is the seventh such report. To the best of our knowledge, it also happens to be the sixth reported case of dorsally exophytic brainstem glioblastoma till date.

Case report: traumatic displacement of a cochlear implant magnet.

Keereweer, Stijn; Van der Schroeff, Marc P; Pullens, Bas

2014-04-01

To date, over 200 000 cochlear implants (CIs) have been implanted worldwide and the incidence is still increasing. We present a case of traumatic displacement of CI magnet to raise awareness about this complication and to highlight the need for vigilance during surgery as well as for proper counseling. The clinical presentation of a 1.5-year-old boy with a traumatic displacement of a CI magnet was presented and the literature was reviewed for this rare complication. After minor head injury, the sound processor could no longer connect to the CI. X-ray imaging demonstrated displacement of the CI magnet. During revision surgery, the magnet was replaced by a new magnet in the silicon holding cap. Intraoperative impedance measurements were normal and the CI was successfully activated 4 weeks postoperatively. Clinicians and patients should be aware of the risk of displacement of the CI magnet after (minor) head injury. Young boys tend to have a higher risk for this complication.

Munchausen syndrome by proxy is an illness which is very difficult to diagnose. It has a high morbidity and mortality rate. The knowledge of the characteristics of the victim and the perpetrator can be quite useful for its early recognition. The American Professional Society on the Abuse of Children, has recently brought the terms for the syndrome up to date. We look at this updating and present six cases diagnosed in our hospital, analysing their main features and comparing them with the medical literature.

Splenic rupture in infectious mononucleosis (Pfeiffer disease, or glandular fever) is a rare but life-threatening complication. The exact mechanism of rupture of the spleen is unknown to date. A case of a spontaneous, asymptomatic, subcapsular haematoma of the spleen of an eighteen-year old female with infectious mononucleosis is presented with special reference to the echographic findings. A complete remission without any complication was obtained. The contribution of the sonographic examination and follow-up in the diagnosis of infectious mononucleosis is emphasised.

Several studies have associated the earlobe crease sign, discovered by Sanders T. Frank in 1973, with cardiovascular pathology, yet very few studies have focused on the antiquity of this trait, with the most ancient one thought to date back to the Roman Emperor Hadrian (76-138CE). This article presents two more cases from the Italian Renaissance in the works of the artist Andrea Mantegna (1431-1506) and examines them in a multidisciplinary fashion.

Cepeda, María de Los Ángeles; Sosa, Ana Julia; Mora, Glenda

Osteosarcoma is one of the most common types of cancer in childhood and adolescence and it is the most common malignant bone tumor in this group of age. Osteosarcoma is frequently found in long bones of the extremities. There are very few cases described in children under 5 years of age, and according to this review, none in infants. The telangiectatic variant is uncommon, and there are no reported cases before preschool age. A 10-month-old female infant with a lithic tumor of the ninth right rib, which was classified after resection as a telangiectatic osteosarcoma, is presented. Telangiectatic osteosarcoma in the pediatric age is very uncommon. To date, the patient has presented good response to treatment, although the prognosis and survival of this condition is unknown.

2008-10-01

This article presents a case study of how the evaluation design for a dating violence prevention and/or youth development program for American Indian youth in Arizona evolved throughout the project. Particular attention is given to how the evaluation design was guided by the tribal participatory research model. A brief rationale for the project is presented along with literature on culturally competent evaluation and research with American Indians. A description of the project and the unique communities in which it was implemented is provided. The focus of the article is the process of how the evaluation plan changed and how various factors influenced this process (e.g., feedback from community stakeholders, conversations with funder, results of process evaluation, suggestions from literature, the authors' experience working in American Indian communities). The authors conclude with lessons learned for others to consider as they develop working relationships and evaluation plans in similar communities.

Pernicious anemia appears classically by macrocytosis. We report a case of a late discovered Biermer disease, on a 42-year-old young black woman. The reason was an unusual aspect of this disease in a context of betathalassemia. The patient presented chronic anemia which evolved during about ten year. Biology showed a normocytosis and signs of hemolysis according to beta-thalassemia. This was confirmed by an electrophoresis showing 9.1 % of fraction F some haemoglobin. Since this date, the patient was treated by folic acid alone with periodic transfusions of red blood cell. She presented eight years after the beginning of her disease, neurological deterioration. Diagnosis of pernicious anemia was finally established up on histological gastritis, low level of the blood rate of vitamin B12, macrocytosis, and presence of intrinsic anti-factor and parietal anti-cells antibodies.

Acute epiglottitis due to Serratia marcescens in an immunocompetent adult.

PubMed

Musham, Chaitanya K; Jarathi, Archana; Agarwal, Abhishek

2012-08-01

Acute epiglottitis (AE) is inflammation of the epiglottis and contiguous tissues, which carries a potential for complete airway obstruction. With routine pediatric immunization for Hemophilus influenzae serotype b, epiglottitis is now more prevalent in adults, with a shift in the causative organisms and a change in the natural history of this disease. Over the past 5 decades, Serratia marcescens has gone from being recognized as a harmless saprophyte to an important opportunistic human pathogen. It is known to be associated with outbreaks of nosocomial infections, but it is an uncommon cause of serious invasive infections in patients presenting from the community. The authors present a fatal case of AE caused by S marcescens in a previously immunocompetent 58-year-old woman, which was complicated by fasciitis, myositis and bacteremia. To the authors' knowledge, till date, only 3 cases of AE by S marcescens have been reported, all in immunocompromised patients.

Orocervical foetus-in-foetu with prenatal sonographic diagnosis: a case report.

PubMed

Braimoh, Kolawole T; Abdulkadir, Adekunle Y; Balogun, Rabiu O

2008-12-04

Foetus-in-foetu is a very rare congenital abnormality where a malformed foetus is included within the body of another foetus. Less than 200 cases have been reported with over 80% occurring in the abdomen. Only three cases of cervical foetus in foetu have been reported. The present case of giant orocervical foetus-in-foetu appears to be an index case. This is a report of an extremely rare orocervical foetus-in-foetu with grotesque oddity diagnosed on prenatal ultrasonography at 35 weeks gestational age in a 28-year-old, G2P1+0, Nigerian woman who was unsure of her last menstrual date or month. The included foetus had two eyes, cranium, nose, long bones and a spine. The mother's attempts at vaginal delivery rather than the elective Caesarean delivery she was offered resulted in obstructed labour and intrauterine foetal demise. Giant cervical foetus-in-foetu is extremely rare. It could result in obstructed labour if vaginal delivery is attempted.

Seismic Moment and Recurrence using Luminescence Dating Techniques: Characterizing brittle fault zone materials suitable for luminescence dating

NASA Astrophysics Data System (ADS)

Tsakalos, E.; Lin, A.; Bassiakos, Y.; Kazantzaki, M.; Filippaki, E.

2017-12-01

During a seismic-geodynamic process, frictional heating and pressure are generated on sediments fragments resulting in deformation and alteration of minerals contained in them. The luminescence signal enclosed in minerals crystal lattice can be affected and even zeroed during such an event. This has been breakthrough in geochronological studies as it could be utilized as a chronometer for the previous seismic activity of a tectonically active area. Although the employment of luminescence dating has in some cases been successfully described, a comprehensive study outlining and defining protocols for routine luminescence dating applied to neotectonic studies has not been forthcoming. This study is the experimental investigation, recording and parameterization of the effects of tectonic phenomena on minerals luminescence signal and the development of detailed protocols for the standardization of the luminescence methodology for directly dating deformed geological formations, so that the long-term temporal behaviour of seismically active faults could be reasonably understood and modeled. This will be achieved by: a) identifying and proposing brittle fault zone materials suitable for luminescence dating using petrological, mineralogical and chemical analyses and b) investigating the "zeroing" potential of the luminescence signal of minerals contained in fault zone materials by employing experimental simulations of tectonic processes in the laboratory, combined with luminescence measurements on samples collected from real fault zones. For this to be achieved, a number of samples collected from four faults of four different geographical regions will be used. This preliminary-first step of the study presents the microstructural, and mineralogical analyses for the characterization of brittle fault zone materials that contain suitable minerals for luminescence dating (e.g., quartz and feldspar). The results showed that the collected samples are seismically deformed fault zone materials (mylonites, tectonites, and tectonic breccias etc) and contained enough quantity of minerals suitable for luminescence dating.

Mothers' reports of play dates and observation of school playground behavior of children having high-functioning autism spectrum disorders.

2011-05-01

Children with high-functioning autism spectrum disorders (ASD) are generally included with typically developing peers at school. They have difficulties interacting with peers on the school playground. Previous literature suggests that having play dates in the home may be related to better peer acceptance at school. This study examines the relationship between mother-reported play date frequency and amount of conflict, and peer interaction observed on the school playground for a sample of 27 boys and 4 girls meeting structured interview and observation criteria for ASD. Measures of intellectual functioning, adaptive behavior, and social skills were included in a stepwise regression analysis to account for their impact on relationships between maternal play date reports, general peer acceptance at school (as rated by the child's teacher) and observations of school playground behavior. Results revealed that children with autism spectrum disorders who had more play dates in their home tended to spend a greater amount of time engaged in behaviors such as mutual offering of objects, conversing and other turn-taking activities with peers on the school playground. They also received more positive responses to their overtures from peers. These relationships remained highly significant even after accounting for other demographic, general social, and cognitive variables. The present results suggest that play date frequency is strongly related to school playground behavior. Owing to the design of this study, future research must assess whether play dates in the home promote better peer relationships on the playground or the reverse. In either case, the assessment of play dates, as well as observation of spontaneous unsupervised social interactions, are important outcome measures to consider in social skills interventions for children with high-functioning ASD. © 2010 The Authors.

Once a year, every country that participates in the European Surveillance Scheme for Travel Associated Legionnaires' Disease (EWGLINET) is asked to submit a dataset comprising all cases of Legionnaires' disease (not only travel-associated) with date of onset in the previous year. This paper presents the data collected for 2005 and 2006. In this period, 11,980 cases were reported by 35 countries, showing a continued increase compared with earlier years. 214 outbreaks or clusters were reported, involving 1028 cases. 377 cases died, giving a case fatality rate of 6.6%. The highest incidence rates in both years were recorded in Spain, while six countries reported a rate of less than one case per million population in at least one of the years. Incidence rates by age group were included in the dataset for the first time, showing an increase of the overall rate with age. Main method of diagnosis was the urinary antigen test (76.0%), whilst the percentage of cases diagnosed by culture fell from 10.0% in previous years to 8.9% in 2005-2006.

Five cases of congenital toxoplasmosis consecutive to a maternal toxoplasma infection that had preceded pregnancy were observed. One woman with normal immune system had developed a well-documented lymph node toxoplasmosis 2 months before conceiving. Four women had chronic toxoplasmosis diagnosed in the course of an immunosuppressive disease: Hodgkin's disease in 1 case, systemic lupus erythematosus in 2 cases and pancytopenia in 1 case. Toxoplasmosis had been recognized 3, 5 and 10 years respectively before conception in 3 women, and at an uncertain date in 1 woman. Three women had received corticosteroids during pregnancy, and 2 had undergone splenectomy. Among the 6 children (2 were twins), 1 presented with severe foetal disease at birth, 1 developed lethal systemic toxoplasmosis after birth, 1 showed hydrocephalus with therapeutically well-controlled chorioretinitis, 1 had isolated eye lesion and 2 had asymptomatic infection. The parasite seems to have been transmitted after the 20th week of pregnancy in all cases. The physiopathology of mother-to child toxoplasma transmission, the role played by maternal immunodeficiency and the practical implications of these exceptional cases are discussed.

Malignant craniopharyngioma or anaplastic craniopharyngioma was first reported in 1987 by Akachi. It has a malignant clinical and histological feature; remarkably rapid progression, atypical pathology like squamous cell carcinoma and poor prognosis. To date seventeen cases of malignant craniopharyngioma have been reported and of these cases, most were of secondary malignant tumor in nature. With respect to traditional benign craniopharyngioma, adjunctive treatment after gross total removal is not necessary, but in the case of malignant types of the tumor, adjunctive treatment is important. This paper presents the first case of malignant craniopharyngioma reactive to adjunctive Gamma knife stereotactic radiosurgery and chemotherapy. Malignant craniopharyngioma is very rare, and we report Gamma knife stereotactic radiosurgery and chemotherapy (Carboplatine and etoposide chemotherapy), as well as Temozolomide chemotherapy were effective and could control progression of the tumor temporarily. Since adjunctive Gamma knife stereotactic radiosurgery and chemotherapy of malignant craniopharyngioma cases affects follow-up strategies, we propose supporting the need to a revision to the WHO classification regarding malignancy evaluation of craniopharyngioma.

Internal fixation combined with bone grafting for large intraosseous calcaneal lipoma: A case report

PubMed Central

Cao, Yongxing

2017-01-01

Intraosseous lipoma is a rare benign bone tumor that has been reported to occur in the calcaneus and long bones. The etiology of intraosseous lipoma is unknown, although several theories have been proposed. The majority of the cases of intraosseous calcaneal lipoma reported in the literature were localized in the anterior portion of the calcaneus and were treated by curettage and bone grafting. However, for larger lipomas, no specific treatment protocol has been developed to date. We herein present a rare case involving a large intraosseous lipoma of the calcaneus in a 36-year-old man following hindfoot trauma. The lesion was treated by decortication followed by bone grafting and internal fixation, a surgical approach that, to the best of our knowledge, has not been previously described in the literature.

2016-01-01

In the majority of cases published between 1907 and 2014, FAS is due to a neurogenic etiology. Only a few reports about FAS with an assumed psychogenic origin have been published. The present article discusses the findings of a careful database search on psychogenic FAS. This review may be particularly relevant as it is the first to analyze the salient features of psychogenic FAS cases to date. This article hopes to pave the way for the view that psychogenic FAS is a cognate of neurogenic FAS. It is felt that this variant of FAS may have been underreported, as most of the psychogenic cases have been published after the turn of the century. This review may improve the diagnosis of the syndrome in clinical practice and highlights the importance of recognizing psychogenic FAS as an independent taxonomic entity. PMID:27199699

The association of Down syndrome (DS) with Dandy Walker malformation (DWM) is extremely rare, with only 3 cases reported to date. All cases reported have shown a bad life expectancy and a bad developmental outcome. The present case reveals the possibility of a good prognosis. A 19-month-old male patient had successful endoscopic hydrocephalus treatment and a good developmental outcome. He probably had a better outcome because of good DS and DWM prognostic parameters. Our patient suffered from a DWM with vermis identification of 2 fissures and 3 lobes and a DS with a well-preserved tonus, which was not associated with other congenital systemic defects. We may conclude that the prognosis of DS-DWM association may separately depend on the degree of clinical and neurological involvement of each malformation. PMID:24932176

A 7-month-old boy presented with gastrointestinal disturbance, mild neurologic deficit of the left lower extremity and levo-scoliosis of the thoracic spine. Magnetic resonance imaging demonstrated a large intramedullary lesion involving the thoracic spine, from level T1 to T11. Histologic analysis showed a glial tumor with fibrillary processes arranged in radial pattern around mucoid fibrovascular cores with a high proliferative index (focally up to 80%) and prominent vascular endothelial hyperplasia. These findings were consistent with an anaplastic myxopapillary ependymoma. Subtotal resection was performed via a T3-T10 laminoplasty. A ventricular shunt was placed, and the patient subsequently received chemoradiation therapy. To date, this is the second case of a myxopapillary ependymoma with high-grade anaplastic features and the first case in an infant reported in the literature.

To date, mental health professionals' attitudes toward posttraumatic stress disorder (PTSD), compared to other psychiatric disorders such as schizophrenia or depression, have rarely been studied. We assessed mental health professionals' attitudes toward patients with PTSD compared to patients suffering from depression. Case vignettes of a patient with either PTSD or depression were presented to two samples of mental health professionals: attendees of a conference on posttraumatic stress (N=226) or of a lecture for psychiatry residents (N=112). Participants subsequently completed a questionnaire that assessed their attitude reactions to the presented case. Participants showed similarly positive attitudes toward depression and PTSD. PTSD elicited a more favorable attitude with regard to prosocial reactions, estimated dependency, attributed responsibility, and interest in the case, particularly in mental health professionals specializing in psychotraumatology. Across diagnoses, higher age and longer professional experience were associated with more positive attitudes toward patients. Mental health professionals' positive attitudes toward patients with depression and PTSD correlate with their specific knowledge about the disorder, their level of professional training, and their years of professional experience. The instruments used, although based on established theoretical concepts in attitude research, were not validated in their present versions.

INTRODUCTION Primary Pulmonary Mucinous Cystadenocarcinoma PPMC is an extremely rare subtype of pulmonary adenocarcinoma, with only a few dozen cases reported in the literature to date. PRESENTATION OF CASE We report a extremely rare case of pulmonary mucinous cystadenocarcinoma presenting as a pleural mesothelioma. 53-year-old man exposed to asbestos, he is admitted in hospital with a 5 cm mass in right pleura. He was treated by wedge resection. Sparse groups of malignant cells were microscopically observed in pools of mucin. The postoperative histopathological findings were in accordance with the diagnosis of pulmonary mucinous cystadenocarcinoma on cystic adenoid malformation of lung. 5 years later, the patient has no recurrence. DISCUSSION PPMC is usually asymptomatic; hemoptysis is seen occasionally. Preoperative diagnosis is very difficult to establish. Both FNA cytology and transbronchial lung biopsy seem inadequate. Our patient went on to undergo open lung biopsy and histopathological testing that confirmed the diagnosis of PMC. CONCLUSION It is important to differentiate this rare pathological feature of the lung from other lung tumors as the treatment is surgical rather than medical. Thoracic surgeons should bear in mind this rare tumor for the differential diagnosis of a pleural mesothelioma because this tumor has a favorable prognosis. PMID:24055913

Posterior reversible encephalopathy as the first manifestation of Bickerstaff's brainstem encephalitis.

Posterior reversible encephalopathy syndrome (PRES) has been associated with Guillain-Barre syndrome in rare cases. Here we report a patient in whom PRES was the presenting manifestation of Bickerstaff's brainstem encephalitis. A 75-year-old woman presented with acute onset of hypertension, headache, blurred vision, and left eyelid drooping. Magnetic resonance imaging of the brain showed characteristic PRES lesions involving the parietal and occipital lobes bilaterally. On the 6th day after symptom onset, the patient developed complete ptosis and external ophthalmoplegia of both eyes, progressive ataxia, and bilateral lower limb weakness. Cerebrospinal fluid analyses revealed albuminocytological dissociation (protein: 66.6 mg/dL, WBC: 0/μl), and nerve conduction studies showed demyelinating sensorimotor polyneuropathy. The patient developed somnolence and a left extensor plantar response on the 8th day. A diagnosis of Bickerstaff's brainstem encephalitis was made. Treatment with plasmapheresis led to a rapid improvement of clinical symptoms. To date, only five similar cases have been reported, but this is the only case in which PRES developed prior to treatment. PRES can be a comorbid condition with Bickerstaff's brainstem encephalitis, either preceding or following treatment; caution should be used in patients with either syndrome who exhibit atypical presentations.

Core biopsy as a simple and effective diagnostic tool in head and neck focal myositis.

2015-12-01

Most unilateral head and neck masses are benign, although malignancy is a possibility in some cases. However, there are other rare causes of unilateral neck masses, such as focal myositis, which is a rare, benign condition belonging to the family of inflammatory pseudotumors of the skeletal muscles, with rare presentations in the head and neck region. Focal myositis presents as a rapidly enlarging neck mass that can be misdiagnosed by fine-needle aspiration biopsy and/or radiologic imaging as either an infective or a neoplastic process. To date, there are only 5 reported cases of adult focal myositis of the sternocleidomastoid muscle in the medical literature. In this article, the authors present 2 cases involving patients with focal myositis of the sternocleidomastoid muscle that were successfully diagnosed with core-needle biopsy and managed conservatively. The pros and cons of fine-needle aspiration biopsy and core-needle biopsy are discussed. Based on the authors' results, fine-needle aspiration biopsy universally fails to provide the diagnosis of focal myositis. In contrast, core-needle biopsy successfully diagnosed focal myositis in both of our patients. Both of them had complete resolution with conservative management.

In Ecuador, cutaneous leishmaniasis (CL) is prevalent countrywide, but only one case of diffuse-CL and two cases of disseminated-CL were experienced during our research activities more than 30 years from 1982 to date. These three patients suffered from multiple lesions distributed at a wide range of the body surface, revealing difficulty to clinically differentiate each other. There is a considerable confusion of the use and/or differentiation of the terminologies (terms) between the two disease forms, diffuse-CL and disseminated-CL. One of the aims of the present study is to clarify the difference between the two disease forms, mainly based on the cases experienced in Ecuador. The disseminated-CL case newly reported here was clinically very similar to the diffuse-CL case, but the former showed the following marked differences from the latter: (1) the organisms isolated were identified as the parasites of Leishmania (Viannia) guyanensis/panamensis, which are also known as the causative agents of disseminated-CL in different endemic countries of the New World; (2) the patient was sensitive against antimonials; and (3) mucosal involvement was observed, which is never observed in diffuse-CL. In the text, three clinical cases, one diffuse-CL and two disseminated-CL, were presented. Furthermore, a bibliographic comparison of the features between the two disease forms was made, and a brief comment was also given.

A Calendar Savant with Episodic Memory Impairments

Patients with memory disorders have severely restricted learning and memory. For instance, patients with anterograde amnesia can learn motor procedures as well as retaining some restricted ability to learn new words and factual information. However, such learning is inflexible and frequently inaccessible to conscious awareness. Here we present a case of patient AC596, a 25-year old male with severe episodic memory impairments, presumably due to anoxia during a preterm birth. In contrast to his poor episodic memory, he exhibits savant-like memory for calendar information that can be flexibly accessed by day, month, and year cues. He also has the ability to recollect the exact date of a wide range of personal experiences over the past 20 years. The patient appears to supplement his generally poor episodic memory by using memorized calendar information as a retrieval cue for autobiographical events. These findings indicate that islands of preserved memory functioning, such as a highly developed semantic memory system, can exist in individuals with severely impaired episodic memory systems. In this particular case, our patient’s memory for dates far outstripped that of normal individuals and served as a keen retrieval cue, allowing him to access information that was otherwise unavailable.

Is there a Lyme-like disease in Australia? Summary of the findings to date.

PubMed

Chalada, Melissa Judith; Stenos, John; Bradbury, Richard Stewart

2016-12-01

Lyme Borreliosis is a common tick-borne disease of the northern hemisphere caused by the spirochaetes of the Borrelia burgdorferi sensu lato ( B. burgdorferi s. l.) complex. It results in multi-organ disease with arthritic, cardiac, neurological and dermatological manifestations. In the last twenty-five years there have been over 500 reports of an Australian Lyme-like syndrome in the scientific literature. However, the diagnoses of Lyme Borreliosis made in these cases have been primarily by clinical presentation and laboratory results of tentative reliability and the true cause of these illnesses remains unknown. A number of animals have been introduced to Australia that may act as B. burgdorferi s. l. reservoirs in Lyme-endemic countries, and there are some Australian Ixodes spp. and Haemaphysalis spp. ticks whose geographical distribution matches that of the Australian Lyme-like cases. Four published studies have searched for Borrelia in Australian ticks, with contradicting results. The cause of the potential Lyme-like disease in Australia remains to be defined. The evidence to date as to whether these illnesses are caused by a Borrelia species, another tick borne pathogen or are due to a novel or unrelated aetiology is summarised in this review.

The estimation of the postmortem interval (PMI) is still one of the most challenging issues in forensic investigations, especially in cases in which advanced transformative phenomena have taken place. The dating of skeletal remains is even more difficult and sometimes only a rough determination of the PMI is possible. Recent studies suggest that plant analysis can provide a reliable estimation for skeletal remains dating, when traditional techniques are not applicable. Forensic Botany is a relatively recent discipline that includes many subdisciplines such as Palynology, Anatomy, Dendrochronology, Limnology, Systematic, Ecology, and Molecular Biology. In a recent study, Cardoso et al. (Int J Legal Med 2010;124:451) used botanical evidence for the first time to establish the PMI of human skeletal remains found in a forested area of northern Portugal from the growth rate of mosses and shrub roots. The present paper deals with a case in which the study of the growth rate of the bryophyte Leptodyctium riparium (Hedw.) Warnst, was used in estimating the PMI of some human skeletal remains that were found in a wooded area near Perugia, in Central Italy. © 2012 American Academy of Forensic Sciences.

To analyse publication and citations trends of case reports within otolaryngology - head and neck surgery literature, with specific attention to the most-cited reports.Study designDatabase query. Web of Science was searched for article type 'case reports' published in the leading otolaryngology - head and neck surgery journals since 1945. Variables including publication dates, citation dates and numbers, author, author number, and others were recorded and analysed for trends. The reports with the most citations (classics) were further studied. Of nearly 67 000 published articles in leading otolaryngology - head and neck surgery journals, the overall number of case reports as a percentage of the total has substantially decreased over time. A total of 110 case report classics were identified for which citations have increased. Although the case report may not be worthy of its tarnished record, declining trends in publication suggest a limited future for this valuable research and educational resource.

Monitoring and evaluating surgical care: defining perioperative mortality rate and standardising data collection.

Case volume per 100 000 population and perioperative mortality rate (POMR) are key indicators to monitor and strengthen surgical services. However, comparisons of POMR have been restricted by absence of standardised approaches to when it is measured, the ideal denominator, need for risk adjustment, and whether data are available. We aimed to address these issues and recommend a minimum dataset by analysing four large mixed surgical datasets, two from well-resourced settings with sophisticated electronic patient information systems and two from resource-limited settings where clinicians maintain locally developed databases. We obtained data from the New Zealand (NZ) National Minimum Dataset, the Geelong Hospital patient management system in Australia, and purpose-built surgical databases in Pietermaritzburg, South Africa (PMZ) and Port Moresby, Papua New Guinea (PNG). Information was sought on inclusion and exclusion criteria, coding criteria, and completeness of patient identifiers, admission, procedure, discharge and death dates, operation details, urgency of admission, and American Society of Anesthesiologists (ASA) score. Date-related errors were defined as missing dates and impossible discrepancies. For every site, we then calculated the POMR, the effect of admission episodes or procedures as denominator, and the difference between in-hospital POMR and 30-day POMR. To determine the need for risk adjustment, we used univariate and multivariate logistic regression to assess the effect on relative POMR for each site of age, admission urgency, ASA score, and procedure type. 1 365 773 patient admissions involving 1 514 242 procedures were included, among which 8655 deaths were recorded within 30 days. Database inclusion and exclusion criteria differed substantially. NZ and Geelong records had less than 0·1% date-related errors and greater than 99·9% completeness. PMZ databases had 99·9% or greater completeness of all data except date-related items (94·0%). PNG had 99·9% or greater completeness for date of birth or age and admission date and operative procedure, but 80-83% completeness of patient identifiers and date related items. Coding of procedures was not standardised, and only NZ recorded ASA status and complete post-discharge mortality. In-hospital POMR range was 0·38% in NZ to 3·44% in PMZ, and in NZ it underestimated 30-day POMR by roughly a third. The difference in POMR by procedures instead of admission episodes as denominator ranged from 10% to 70%. Age older than 65 years and emergency admission had large independent effects on POMR, but relatively little effect in multivariate analysis on the relative odds of in-hospital death at each site. Hospitals can collect and provide data for case volume and POMR without sophisticated electronic information systems. POMR should initially be defined by in-hospital mortality because post-discharge deaths are not usually recorded, and with procedures as denominator because details allowing linkage of several operations within one patient's admission are not always present. Although age and admission urgency are independently associated with POMR, and ASA and case mix were not included, risk adjustment might not be essential because the relative odds between sites persisted. Standardisation of inclusion criteria and definitions is needed, as is attention to accuracy and completeness of dates of procedures, discharge and death. A one-page, paper-based form, or alternatively a simple electronic data collection form, containing a minimum dataset commenced in the operating theatre could facilitate this process. None.

"This paper investigates birth-date dependent principles for social evaluation in an intertemporal framework in which population size may vary. We weaken the strong Pareto principle in order to allow individuals' birth dates to matter in establishing a social ordering. Using the axiom independence of the utilities of the dead, we characterize population principles with a recursive structure. If the individual substitution principle and an individual intertemporal equivalence axiom are added, birth-date dependent generalizations of the critical-level generalized utilitarian principles result. Stationarity leads to the special case of geometric discounting." excerpt

NASA 9-Point LDI Code Validation Experiment

Hicks, Yolanda R.; Anderson, Robert C.; Locke, Randy J.

2007-01-01

This presentation highlights the experimental work to date to obtain validation data using a 9-point lean direct injector (LDI) in support of the National Combustion Code. The LDI is designed to supply fuel lean, Jet-A and air directly into the combustor such that the liquid fuel atomizes and mixes rapidly to produce short flame zones and produce low levels of oxides of nitrogen and CO. We present NOx and CO emission results from gas sample data that support that aspect of the design concept. We describe this injector and show high speed movies of selected operating points. We present image-based species maps of OH, fuel, CH and NO obtained using planar laser induced fluorescence and chemiluminescence. We also present preliminary 2-component, axial and vertical, velocity vectors of the air flow obtained using particle image velocimetry and of the fuel drops in a combusting case. For the same combusting case, we show preliminary 3-component velocity vectors obtained using a phase Doppler anemometer. For the fueled, combusting cases especially, we found optical density is a technical concern that must be addressed, but that in general, these preliminary results are promising. All optical-based results confirm that this injector produces short flames, typically on the order of 5- to-7-mm long at typical cruise and high power engine cycle conditions.

Assessing TNT and DNT groundwater contamination by compound-specific isotope analysis and 3H-3He groundwater dating: a case study in Portugal.

PubMed

Amaral, Helena I F; Fernandes, Judite; Berg, Michael; Schwarzenbach, René P; Kipfer, Rolf

2009-10-01

Trinitrotoluene (TNT) and dinitrotoluene (DNT) originating from 50 years of explosives production have heavily contaminated two stacked aquifers in the vicinity of Lisboa, Portugal. To assess if these poly-nitroaromatic compounds (P-NACs) are being degraded in the subsurface, tracer-based groundwater dating techniques combined with compound-specific isotope analyses (CSIA) were applied. The groundwater residence times were distinctly different in the two aerobic aquifers, as determined by the tritium ((3)H)-(3)He method. In the contaminated zones, the upper aquifer exhibited groundwater ages of 25 years, whereas the lower (presumably confined) aquifer contained hardly any tritium which indicates water ages >55 years. P-NACs-containing waste waters are known to have leaked into the upper, unconfined aquifer. However, P-NACs were present in both aquifers in high concentrations (up to 33000 microg L(-1) TNT), which implies a hydraulic connection, although tritium concentrations and chemical data suggest two separated aquifers. Based on the (3)H-(3)He groundwater dating and the presence of very high P-NAC concentrations, the contamination of the lower aquifer must have happened during the early stage of the explosive production, i.e. >50 years ago. Despite this 'old' contamination, TNT and DNT have not been transformed until to date as is demonstrated by the negligible changes in their carbon isotopic signatures (delta(13)C). Thus, P-NACs are very recalcitrant to degradation at the investigated site. If the aquifers remain aerobic, TNT and DNT are expected to persist in the subsurface for many decades to centuries. The presented approach of assessing time scales of natural attenuation at the field scale by the combination of CSIA and (3)H-(3)He water dating has the potential to be applied to any other groundwater contaminants, such as chlorinated hydrocarbons, gasoline components, heterocyclic carbenes, or polyaromatic hydrocarbons.

Posttraumatic Intracranial Tuberculous Subdural Empyema in a Patient with Skull Fracture

PubMed Central

Kim, Jiha; Kim, Choonghyo; Ryu, Young-Joon

2016-01-01

Intracranial tuberculous subdural empyema (ITSE) is extremely rare. To our knowledge, only four cases of microbiologically confirmed ITSE have been reported in the English literature to date. Most cases have arisen in patients with pulmonary tuberculosis regardless of trauma. A 46-year-old man presented to the emergency department after a fall. On arrival, he complained of pain in his head, face, chest and left arm. He was alert and oriented. An initial neurological examination was normal. Radiologic evaluation revealed multiple fractures of his skull, ribs, left scapula and radius. Though he had suffered extensive skull fractures of his cranium, maxilla, zygoma and orbital wall, the sustained cerebral contusion and hemorrhage were mild. Eighteen days later, he suddenly experienced a general tonic-clonic seizure. Radiologic evaluation revealed a subdural empyema in the left occipital area that was not present on admission. We performed a craniotomy, and the empyema was completely removed. Microbiological examination identified Mycobacterium tuberculosis (M. tuberculosis). After eighteen months of anti-tuberculous treatment, the empyema disappeared completely. This case demonstrates that tuberculosis can induce empyema in patients with skull fractures. Thus, we recommend that M. tuberculosis should be considered as the probable pathogen in cases with posttraumatic empyema. PMID:27226867

Forensic applications of 14C at CIRCE

NASA Astrophysics Data System (ADS)

Marzaioli, F.; Fiumano, V.; Capano, M.; Passariello, I.; Cesare, N. De.; Terrasi, F.

2011-12-01

The decreasing trend of the radiocarbon pulse produced during the atmospheric tests of nuclear weapons (bomb-carbon) coupled with high sensitivity accelerator mass spectrometry (AMS) measurements, drastically increased the precision of radiocarbon age determinations since the second part of the sixties, allowing the application of radiocarbon AMS to a wide range of studies previously not directly involving conventional radiocarbon dating (i.e. food authenticity, forensic, biochemistry). In the framework of authenticity evaluation of artworks, high precision radiocarbon ( 14C) AMS measurements (Δ R/ R < 0.3%) reduce the conventional uncertainty of the dating to few decades, allowing precise age estimation of materials containing carbon (C). The Centre for Isotopic Research on Cultural and Environmental heritage (CIRCE) during its activity on AMS 14C dating achieved high precision measurements opening the opportunity to these kinds of applications. This paper presents the main results obtained from radiocarbon measurements on a set of bone samples analyzed for the determination of the post-mortem interval in the framework of an unsolved case investigated by the Rome prosecutor office. The chronological characterization of the wooden support of the "Acerenza portrait" is also presented with the aim to evaluate its age and to further investigate the possibility to attribute this artwork to Leonardo da Vinci. Bomb- 14C dating on the lipid and collagen fractions of bones allows the evaluation of the year of the death of the individuals by means of ad hoc calibration data sheet with the typical few years precision and difference between collagen apparent age and the year of death appeared in agreement with the age of one individual estimated by dating of tooth collagen. Conventional radiocarbon dating on both wood and wood extracted cellulose leads to an estimation of the portrait wood board age (2σ) of 1459-1524 AD (57% relative probability), 1571-1631 AD interval (42% relative probability).and 1559-1563 AD (1% relative probability). These results attribute with the highest relative probability an age comprised within the life span of Leonardo (1452-1519) to the support.

Rare presentation of subcapsular hepatic steatosis in a woman with uncontrolled diabetes without peritoneal dialysis: a case report.

PubMed

Chowdhary, Varun; Pernicka, Jennifer S Golia; Sharma, Richa

2016-12-20

Subcapsular hepatic steatosis is a rare atypical pattern of fatty deposition of the liver reported in patients with diabetic nephropathy receiving peritoneal dialysis with intraperitoneal insulin. To date, there has been only one pediatric and zero adult cases of subcapsular hepatic steatosis with no history of continuous ambulatory peritoneal dialysis. We report the first published case of subcapsular hepatic steatosis in an adult diabetic patient without any history of peritoneal dialysis or evidence of chronic renal disease. A 46-year-old Caucasian woman with type 2 diabetes mellitus without renal disease presented to our emergency department with vague abdominal symptoms and vomiting. Her blood glucose levels were poorly controlled with a range of 400 to 500 mg/dL. She was diagnosed as having subcapsular hepatic steatosis based on magnetic resonance imaging. Of note, after improved glucose control her subcapsular hepatic steatosis had nearly resolved. Subcapsular hepatic steatosis has been exclusively described in patients with continuous ambulatory peritoneal dialysis and those on intraperitoneal insulin, except for one pediatric case, which was probably due to incorrect insulin administration. Our case demonstrates that a diagnosis of subcapsular hepatic diagnosis should not be restricted to those getting continuous ambulatory peritoneal dialysis, but rather expanded to all patients with uncontrolled blood glucose levels.

Preventing emergence of new zoonotic viruses depends on understanding determinants for human risk. Nipah virus (NiV) is a lethal zoonotic pathogen that has spilled over from bats into human populations, with limited person-to-person transmission. We examined ecologic and human behavioral drivers of geographic variation for risk of NiV infection in Bangladesh. We visited 60 villages during 2011–2013 where cases of infection with NiV were identified and 147 control villages. We compared case villages with control villages for most likely drivers for risk of infection, including number of bats, persons, and date palm sap trees, and human date palm sap consumption behavior. Case villages were similar to control villages in many ways, including number of bats, persons, and date palm sap trees, but had a higher proportion of households in which someone drank sap. Reducing human consumption of sap could reduce virus transmission and risk for emergence of a more highly transmissible NiV strain. PMID:28820130

Fatal Intracranial Hemorrhage in a Patient with Severe Dengue Fever

PubMed Central

Sam, Jo Ee; Gee, Teak Sheng; Wahab, Nasser Abdul

2018-01-01

Dengue fever has been a major cause of morbidity and mortality in subtropical and tropical countries. We report a rare case of severe dengue with spontaneous intracranial hemorrhage. A search of literature through PubMed revealed that the largest series analyzed so far only included five cases. A 47-year-old man presented with 7 days history of fever, headache, myalgia, and vomiting with hematemesis. On the day of presentation, he had reduced consciousness and an episode of generalized tonic-clonic seizure. His Glasgow Coma Scale was E1V1M3 with anisocoria. Postresuscitation computed tomography of the brain revealed a right subdural and left thalamic hemorrhage. His blood investigations revealed thrombocytopenia, dengue virus type 1 nonstructural protein antigen test was positive, dengue IgM negative, and dengue IgG positive. A right decompressive craniectomy was done. Unfortunately, the patient died soon after. Spontaneous intracranial hemorrhage in patients with dengue fever is an uncommon entity but usually carry a grave prognosis. To date, there has been no clear management guideline for such cases, as both operative and nonoperative approaches have their own inherent risks. PMID:29492121

Medulloblastoma is the most common malignant brain tumor in children. To date only few cases of medulloblastoma with hemorrhages have been reported in the literature. Although some studies speculate on the pathogenesis of this anomalous increased vascularization in medulloblastoma, the specific mechanism is still far from clearly understood. A correlation between molecular medulloblastoma subgroups and hemorrhagic features has not been reported, although recent preliminary studies described that WNT-subtype tumors display increased vascularization and hemorrhaging. Herein, we describe a child with a Wnt-medulloblastoma presenting as cerebellar-vermian hemorrhagic lesion. Brain magnetic resonance imaging (MRI) showed the presence of a midline posterior fossa mass with a cystic hemorrhagic component. The differential diagnosis based on imaging included cavernous hemangioma, arteriovenous malformation and traumatic lesion. At surgery, the tumor appeared richly vascularized as documented by the preoperative angiography. The case we present showed that Wnt medulloblastoma may be associated with anomalous vascularization. Further studies are needed to elucidate if there is a link between the hypervascularization and the Wnt/β-catenin signaling activation and if this abnormal vasculature might influence drug penetration contributing to good prognosis of this medulloblastoma subgroup.

Chronic traumatic encephalopathy in contact sports: a systematic review of all reported pathological cases.

2015-01-01

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease associated with head trauma. Although initially believed to affect only boxers, the at-risk population has expanded to encompass a much wider demographic, including American football players, hockey players, wrestlers, and military veterans. This expansion has garnered considerable media attention and public concern for the potential neurodegenerative effects of head trauma. The main aim of this systematic review is to give a complete overview of the common findings and risk factors for CTE as well as the status quo regarding the incidence and prevalence of CTE. This systematic review was performed using PubMed and MEDLINE and includes all neuropathologically confirmed cases of CTE in the medical literature to date, from the first published case in 1954 to August 1, 2013 (n = 153). The demographics, including the primary source of mTBI (mild Traumatic Brain Injury), age and cause of death, ApoE genotype, and history of substance abuse, when listed, were obtained from each case report. The demographics of American football players found to have CTE are also presented separately in order to highlight the most prevalent group of CTE cases reported in recent years. These 153 case reports of CTE represent the largest collection to date. We found that a history of mTBI was the only risk factor consistently associated with CTE. In addition, we found no relationships between CTE and age of death or abnormal ApoE allele. Suicide and the presence of premorbid dementia was not strongly associated with CTE. We conclude that the incidence of CTE remains unknown due to the lack of large, longitudinal studies. Furthermore, the neuropathological and clinical findings related to CTE overlap with many common neurodegenerative diseases. Our review reveals significant limitations of the current CTE case reporting and questions the widespread existence of CTE in contact sports.

Environment and Paediatric Cancer (PC) in the Region of Murcia (RM) is an on-going research project that has the following aims: to collect a careful paediatric environmental history (PEH) and to use geographical information systems (GIS) to map the incidence and analyze the geographic distribution of the PC incidence in the RM. The objectives are to present the methodology used for the collection and processing of data and disseminate initial results on the spatial and temporal incidence of PC in the RM (Spain). A descriptive and georeference study of all PC cases under 15 years, diagnosed from 1 January 1998 to December 31, 2009. Three postal addresses were assigned to each case, residence during pregnancy, postnatal, and at the time of diagnosis. Other variables such as sex, date of birth, date of diagnosis, and histopathology classification were collected. No increase was observed in the trend of incidence of PC. The crude annual incidence rate was 14.3 cases per 100,000 children under 15 years. The standardised incidence ratio was higher in the north-west of the RM. Before diagnosis, 30% of cases had a different postal address than during the pregnancy. Integrating the spatial and temporal information through the PEH in a GIS should allow the identification and study of space-time clusters through an environmental monitoring system in order to know the importance of associated risk factors.

Local brain herniation after removal of chronic subdural haematoma is extremely rare, especially in adult patients. This study reports a case of local brain herniation after partial membranectomy for organized chronic subdural haematoma. A 77-year-old man presented with dysarthria and dysphasia caused by local brain herniation of the right frontal lobe through a defect of the inner membrane. The herniated brain was detected by magnetic resonance (MR) imaging. The patient underwent a craniotomy to release the herniated and strangulated brain, which were consistent with the MR imaging findings. The patient recovered fully within 1 month after surgery. To date, five cases of brain herniation through the internal subdural membrane have been reported as complications of chronic subdural haematomas. All but one case occurred in the paediatric population. Urgent surgery should be performed, even if an adult patient suffers from local brain herniation, for preservation of brain function. This is the sixth reported case of brain herniation through a defect of the inner membrane and the second reported case in the adult population.

Larval cases of caddisfly (Insecta: Trichoptera) affinity in Early Permian marine environments of Gondwana

Caddisflies (Trichoptera) are small, cosmopolitan insects closely related to the Lepidoptera (moths and butterflies). Most caddisflies construct protective cases during their larval development. Although the earliest recognisable caddisflies date back to the early Mesozoic (Early and Middle Triassic), being particularly numerous and diverse during the Late Jurassic and Early Cretaceous, the first records of their larval case constructions are known exclusively from much younger, Early to Middle Jurassic non-marine deposits in the northern hemisphere. Here we present fossils from the Early Permian (Asselian-Sakmarian) marine deposits of Brazil which have strong morphological and compositional similarity to larval cases of caddisflies. If they are, which is very probable, these finds not only push back the fossil record of true caddisflies, but also indicate that their larvae constructed cases at the very beginning of their evolution in marine environments. Since modern caddisflies that construct larval cases in marine environments are only known from eastern Australia and New Zealand, we suggest that this marine ecology may have first evolved in western Gondwana during the Early Permian and later spread across southern Pangea.

An increase in cases of pertussis, mainly in young infants, has been reported in the last few years. The clinical presentation of this disease is very similar to that produced by respiratory syncytial virus (RSV), which makes the diagnosis difficult. To compare the clinical and epidemiological characteristics between Bordetella pertussis and RSV infections in infants admitted to hospital. An analytical matched case-control study was conducted during the period 2008-2011. Cases were defined as infants admitted with pertussis confirmed by PCR in nasopharyngeal aspirate. Each case was matched by age, sex and date of admission to two controls defined as patients with RSV infection detected by immunochromatography in nasal aspirate. Demographic, clinical, laboratory data were compared. Seventy eight patients (26 cases of pertussis and 52 controls RSV+) were included. Sociodemographic characteristics were similar in both groups. Cases had more days of symptoms prior to admission, longer hospital stays, and increased frequency of epidemic family environment. Apnoea and cyanosis were more frequent. Cases of pertussis were more likely to have apnoea, cyanosis, and lymphocytosis while RSV infections had more frequent fever, vomiting and respiratory distress. The clinical presentations of pertussis and RSV infection are similar, but there are some characteristics that can help to distinguish between them.

Trisomy 18 is the second most common chromosomal syndrome and has multiple dysmorphic features. However, ocular findings in trisomy 18 are rarely reported. Retinal folds are the most common ocular finding described to date, although retinal hypopigmentation, dysplasia, and areas of hemorrhage and gliosis are also found in trisomy 18. Dandy-Walker syndrome is a brain malformation that has been reported in association with numerous chromosomal abnormalities, although it has rarely been reported in association with trisomy 18. Here, we present a case of trisomy 18 with ocular pathology and variant of Dandy-Walker syndrome, a combination that has not previously been reported. Copyright © 2010 Taiwan Pediatric Association.

Necrotising otitis externa in the immunocompetent patient: case series.

PubMed

Unadkat, S; Kanzara, T; Watters, G

2018-01-01

Necrotising otitis externa can be a devastating form of otitis externa. It typically tends to affect patients who are immunocompromised or diabetic. To date, there is very little in the literature about necrotising otitis externa in the immunocompetent patient population. The present paper discusses both the clinical and radiological findings in three cases of necrotising otitis externa in an immunocompetent patient cohort. The common factor among all three patients was their advanced age. Diagnosing necrotising otitis externa can be challenging because of the potentially non-specific symptoms and the absence of early radiological signs, particularly if patients are neither immunocompromised nor diabetic. Elderly patients should be considered in the same light as immunocompromised and diabetic patients in the context of necrotising otitis externa.

Gravity-Assist Trajectories to the Ice Giants: An Automated Method to Catalog Mass- Or Time-Optimal Solutions

NASA Technical Reports Server (NTRS)

Hughes, Kyle M.; Knittel, Jeremy M.; Englander, Jacob A.

2017-01-01

This work presents an automated method of calculating mass (or time) optimal gravity-assist trajectories without a priori knowledge of the flyby-body combination. Since gravity assists are particularly crucial for reaching the outer Solar System, we use the Ice Giants, Uranus and Neptune, as example destinations for this work. Catalogs are also provided that list the most attractive trajectories found over launch dates ranging from 2024 to 2038. The tool developed to implement this method, called the Python EMTG Automated Trade Study Application (PEATSA), iteratively runs the Evolutionary Mission Trajectory Generator (EMTG), a NASA Goddard Space Flight Center in-house trajectory optimization tool. EMTG finds gravity-assist trajectories with impulsive maneuvers using a multiple-shooting structure along with stochastic methods (such as monotonic basin hopping) and may be run with or without an initial guess provided. PEATSA runs instances of EMTG in parallel over a grid of launch dates. After each set of runs completes, the best results within a neighborhood of launch dates are used to seed all other cases in that neighborhood-allowing the solutions across the range of launch dates to improve over each iteration. The results here are compared against trajectories found using a grid-search technique, and PEATSA is found to outperform the grid-search results for most launch years considered.

EMTG finds gravity-assist trajectories with impulsive maneuvers using a multiple-shooting structure along with stochastic methods (such as monotonic basin hopping) and may be run with or without an initial guess provided. PEATSA runs instances of EMTG in parallel over a grid of launch dates. After each set of runs completes, the best results within a neighborhood of launch dates are used to seed all other cases in that neighborhood---allowing the solutions across the range of launch dates to improve over each iteration. The results here are compared against trajectories found using a grid-search technique, and PEATSA is found to outperform the grid-search results for most launch years considered.

Rhodotorula species are increasingly being identified as a cause of fungal infection in the central nervous system, especially in patients with compromised immunity. The diagnosis could easily be missed due to low index of suspicion, as cryptococcus meningitis and cerebral toxoplasmosis are more common amongst immunocompromised hosts. To date, there are six cases of Rhodotorula-related meningitis reported, and three are associated with human immunodeficiency virus infection. In this report, a case of a Malaysian male with underlying human immunodeficiency virus infection who developed Rhodotorula mucilaginosa meningitis is presented. High-grade fever and severe headaches were the complaints presented in three previous case reports. India ink and nigrosin stainings were performed in the two previous reports and both revealed positive results. R. mucilaginosa were isolated from the culture of the patient's cerebrospinal fluid in all three previous reports. Predominant lymphocyte infiltration in the cerebrospinal fluid examination was documented in two reports. CD4 counts were above 100/µl in two previously published reports, while another report documented CD4 count as 56/µl. Amphotericin B and itraconazole are identified to be the first line of antifungal used and as the maintenance therapy, respectively. The possibility of relapse cannot be excluded as it was reported in the first report. It was also revealed that the current case has almost similar clinical presentation and therapeutic outcome as compared to the published reports, but some differences in diagnostic details were to be highlighted.

Following almost 30 years of relative silence, chikungunya fever reemerged in Kenya in 2004. It subsequently spread to the islands of the Indian Ocean, reaching Southeast Asia in 2006. The virus was first detected in Cambodia in 2011 and a large outbreak occurred in the village of Trapeang Roka Kampong Speu Province in March 2012, in which 44% of the villagers had a recent infection biologically confirmed. The epidemic curve was constructed from the number of biologically-confirmed CHIKV cases per day determined from the date of fever onset, which was self-reported during a data collection campaign conducted in the village after the outbreak. All individuals participating in the campaign had infections confirmed by laboratory analysis, allowing for the identification of asymptomatic cases and those with an unreported date of fever onset. We develop a stochastic model explicitly including such cases, all of whom do not appear on the epidemic curve. We estimate the basic reproduction number of the outbreak to be 6.46 (95% C.I. [6.24, 6.78]). We show that this estimate is particularly sensitive to changes in the biting rate and mosquito longevity. Our model also indicates that the infection was more widespread within the population on the reported epidemic start date. We show that the exclusion of asymptomatic cases and cases with undocumented onset dates can lead to an underestimation of the reproduction number which, in turn, could negatively impact control strategies implemented by public health authorities. We highlight the need for properly documenting newly emerging pathogens in immunologically naive populations and the importance of identifying the route of disease introduction.

Mosqueda-Taylor, Adalberto; Domínguez-Malagon, Hugo; Cano-Valdez, Ana-Maria; Montiel-Hernandez, Ana-Maria

2009-04-01

Meningiomas are benign tumors of mesodermal origin that arise from arachnoid cell clusters that penetrate the dura to form arachnoid villi. These neoplasms represent one of the most common neoplasms developing within the central nervous system and are usually located at points of entry of vessels and nerves through the dura. Extracranial meningiomas (EM) comprise only 2% of all meningiomas, and only six cases of primary EM of the jawbones have been described to date. They may arise as an extension of intracranial meningiomas or as primary tumors and may be clinically indistinguishable from other benign tumours of the jaws, as they usually present as a well-delineated unencapsulated tumors. In this article a case of primary intramandibular primary EM that appeared as a well-defined osteolytic radiolucent lesion of the jaw is reported. The salient clinico-pathological features of this case is compared to those previously reported in the literature and differential diagnosis and therapeutic considerations are discussed.

Lupus mastitis as a first manifestation of systemic disease: About two cases with a review of the literature.

2017-07-01

Lupus mastitis is an uncommon manifestation of systemic lupus erythematosus (SLE) that affects the subcutaneous fat in the breast, much like lupus panniculitis, but additionally involves the mammary gland. We report on two women for whom lupus mastitis was the initial manifestation of SLE and provide a literature review of 34 additional cases reported in the Anglo-Saxon and French literature since 1971, making this the largest review to date. Lupus mastitis (LM) can manifest clinically as subcutaneous masses that may be painful, or may present cutaneous involvement such as thickening and discolouration. The radiologic manifestations of LM are broad and include calcifications, masses and asymmetries. Most often, excluding malignancy requires percutaneous biopsy, with histologic findings that are virtually pathognomonic for SLE. Thus, surgery is avoided and medical management can begin, antimalarial drugs and corticosteroids in most cases. Copyright © 2017 Elsevier B.V. All rights reserved.

Orthognathic Surgery for the Correction of Severe Skeletal Class III Malocclusion.

PubMed

Kafle, D; Upadhayaya, C; Chaurasia, N; Agarwal, A

2016-01-01

Skeletal Malocclusions results from the abnormal position of maxilla and mandible in relation with cranial base. These types of malocclusion are commonly treated by orthodontic teeth movement known as camouflage orthodontics. However severe skeletal malocclusions cannot be treated by orthodontics alone. Such cases need surgical intervention to align the position of the jaw along with orthodontic correction. This procedure is commonly known as Orthognathic Surgery. Orthognathic Surgery dates back to early eighteenth century but became popular on mid twentieth century. Though the prevalence of skeletal malocclusion is more than 1% the treatment facility was not available in Nepal till 2012. Here we present a case of Skeletal Class III malocclusion treated at Dhulikhel Hospital, Kathmandu University Hospital. For this case, double jaw surgery was performed by le-Fort I osteotomy and Bilateral Sagital Split Osteotomy. Orthognathic surgery has been routinely performed at this centre since then.

Iatrogenic orthodontic dental trauma: a case report.

2013-01-01

Iatrogenic trauma can be defined as any adverse condition in a patient resulting from treatment by a physician or dentist. Orthodontic treatment carries with it the risks of tissue damage and treatment failure. The aim of this article is to present traumatic oral tissue lesions resulting from iatrogenic orthodontic origin with a 2-year follow-up period based on orthodontic intervention followed by periodontal surgery. The management of traumatic injuries is dependent on the severity of the involvement of the periodontal tissues. While, in most cases, the elimination of the offending agent and symptomatic therapy is sufficient, in severe cases, or when the injury resulted in permanent defects, periodontal/regenerative therapy may be necessary. The dentist must be aware of these risks in order to help the patient make a fully informed choice whether to proceed with orthodontic treatment. The skill, experience, and up-to-date knowledge of dentists are the main factors to prevent possible iatrogenic traumas.

Cutaneous Collagenous Vasculopathy

PubMed Central

Ortleb, Melanie; Boyd, Alan S.; Powers, Jennifer

2015-01-01

Cutaneous collagenous vasculopathy is a rare microangiopathy of dermal blood vessels. Clinically indistinguishable from generalized essential telangiectasia, this condition is diagnosed by its unique histological appearance. In contrast to other primary telangiectatic processes, cutaneous collagenous vasculopathy has dilated vascular structures that contain deposits of eosinophilic hyaline material within the vessel walls. To date, cutaneous collagenous vasculopathy has been described in a total of 19 cases in the medical literature. The first several cases were described exclusively in middle-aged to elderly men. Though it has now been described in both men and women, cutaneous collagenous vasculopathy is still most often described in middle-aged to older adults. No particular disease or medication has been linked to the development of cutaneous collagenous vasculopathy, and the etiology remains unknown. In this case series, the authors present three additional patients diagnosed with cutaneous collagenous vasculopathy and discuss their clinical and histopathologic features. PMID:26705441

A case of melanocytic cervical adenosquamous carcinoma complicated with Cushing's syndrome.

2017-01-01

To date, cervical carcinoma complicated with Cushing's syndrome were all diagnosed as small cell carcinoma histo- logically, but not adenosquamous carcinoma. Here the authors present the diagnosis, management, and prognosis of a case of melanocytic cervical adenosquamous carcinoma complicated with Cushing's syndrome. A 28-year-old woman was admitted with the chief complaint of post-coital bleeding for one month. Gynecological examination revealed a nodular yellowish-pigmented vegetation (6x5 cm) on the cervix. Laboratory findings proved the diagnosis of Cushing's syndrome. Histopathological diagnosis showed the adenosquamous carcinoma with melanoma differentiation. Immunohistochemical stainings for melanoma A and anti- adrenocorticotropic hormone (ACTH) were positive in the majority of the tumor cells, which indicated that this melanocytic cervical carcinoma lesion was the source of ectopic ACTH production resulting in Cushing's syndrome. This is a unique case of a rare type of cervical carcinoma.

An interesting case of isolated pancreatic teratoma: lessons to learn.

Mature cystic teratomas of the pancreas are extremely rare tumours encountered in day-to-day clinical practice. Only few cases have been reported to date involving all age groups. The management, diagnosis and evaluation of this tumor are questionable, with definitive diagnosis taking place intra-operatively. We hereby report the case in a 30 year-old-male who presented with newly diagnosed diabetes mellitus and during the follow up he was noted to have elevated liver enzymes clinically, he was asymptomatic. The computerized tomography revealed a retropancreatic mass and pushing the mesenteric veins anteriorly. The mass was hypodense in nature and there was presence of calcification. Although the patient was asymptomatic, the decision for resecting the mass was made in view of the size and possibility of malignancy. In conclusion, considering the size and approximity of the mass to the pancreas, Whipple procedure's is the most appropriate approach although the histological diagnosis has not been established preoperatively.

A case of non-arteritic anterior ischemic optic neuropathy after completion of Harvoni therapy.

Manoharan, Niranjan; Subramanian, Prem Sagar

2017-06-01

To report the first reported case of non-arteritic anterior ischemic optic neuropathy (NAION) associated with the use of Harvoni (Gilead Sciences, Foster City, CA, USA), a newly approved treatment for Hepatitis C. We report a case of NAION in a hepatitis C patient who completed Harvoni therapy just prior to presentation. Harvoni was suspected to be the causative agent given a lack of NAION risk factors in an otherwise healthy young patient. NAION is an acute, painless vision loss that typically affects adults over 50. The mechanism of NAION remains uncertain although numerous associations have been identified including certain medications. Harvoni, a combination drug of ledipasvir/sofosbuvir, is a recently FDA-approved treatment for Hepatitis C. To date, however, no ophthalmological side effects have been reported with its use. Continued surveillance of patients treated with Harvoni will be needed to determine if additional events are observed in the future.

Integrating age information from different localities for stratigraphic marker beds: discussion of the Eltville Tephra age (Western Europe)

NASA Astrophysics Data System (ADS)

Zeeden, Christian; Zens, Joerg; Lehmkuhl, Frank

2015-04-01

Stratigraphic marker beds are often used in geosciences for regional and global correlation. For various reasons dating those layers directly proves to be difficult sometimes. In such cases ages from above and below such a horizon represent minimum- and maximum-ages. If these ages are determined from more than one location, it is possible to combine these ages, test their consistency and finally derive an age in agreement with the findings from most localities. Several approaches to integrate the age information from different localities are discussed, resulting in combined ages consistent with both stratigraphy and most of the dating results. All approach rely on assumptions, most importantly the correctness of ages and their reported uncertainty. The Eltville Tephra originates from an unknown eruption in the Eifel volcanic field is an important maker bed in Rhine-Meuse Area nearby the boundary between the deposition of reworked and primary loess during the LGM (ca. 20 ka). The Eltville Tephra is usually imbedded in loess; dates from directly above and below come almost exclusively from luminescence dating. As different luminescence dating techniques were applied to samples over- and underlying the Eltville Tephra a systematic bias of the sum of these techniques seems unlikely, but may be present due to the fact that most ages are feldspar ages uncorrected for fading. The results of several statistical approaches to deal with ages from various localities are compared, and their chances and shortcomings using well understood artificial data are discussed. These are also used to obtain an integrated datum for the Eltville Tephra including a reproducible uncertainty. This has the potential to improve on existing dates for various other stratigraphic marker beds especially in the terrestrial realm, where often dates for (or around) correlative sediments are obtained from various localities.

Temporal overlap of humans and giant lizards (Varanidae; Squamata) in Pleistocene Australia

An obvious but key prerequisite to testing hypotheses concerning the role of humans in the extinction of late Quaternary 'megafauna' is demonstrating that humans and the extinct taxa overlapped, both temporally and spatially. In many regions, a paucity of reliably dated fossil occurrences of megafauna makes it challenging, if not impossible, to test many of the leading extinction hypotheses. The giant monitor lizards of Australia are a case in point. Despite commonly being argued to have suffered extinction at the hands of the first human colonisers (who arrived by 50 ka), it has never been reliably demonstrated that giant monitors and humans temporally overlapped in Australia. Here we present the results of an integrated U-Th and 14C dating study of a late Pleistocene fossil deposit that has yielded the youngest dated remains of giant monitor lizards in Australia. The site, Colosseum Chamber, is a cave deposit in the Mt Etna region, central eastern Australia. Sixteen new dates were generated and demonstrate that the bulk of the material in the deposit accumulated since ca. 50 ka. The new monitor fossil is, minimally, 30 ky younger than the previous youngest reliably dated record for giant lizards in Australia and for the first time, demonstrates that on a continental scale, humans and giant lizards overlapped in time. The new record brings the existing geochronological dataset for Australian giant monitor lizards to seven dated occurrences. With such sparse data, we are hesitant to argue that our new date represents the time of their extinction from the continent. Rather, we suspect that future fossil collecting will yield new samples both older and younger than 50 ka. Nevertheless, we unequivocally demonstrate that humans and giant monitor lizards overlapped temporally in Australia, and thus, humans can only now be considered potential drivers for their extinction.

Adrenal tumors with more than one cellular component are uncommon. Furthermore, an adrenal tumor composed of a pheochromocytoma and a malignant peripheral nerve sheath tumor is extremely rare. A composite pheochromocytoma with malignant peripheral nerve sheath tumor in a 42-year-old man is reported here. After adequate preoperative control, left adrenalectomy was performed simultaneously with resection of the ipsilateral kidney for spontaneous rupture of the left adrenal tumor. Pathological findings demonstrated pheochromocytoma and malignant peripheral nerve sheath tumor in a ruptured adrenal tumor. To date, there have been only four reported cases of composite pheochromocytoma with malignant peripheral nerve sheath tumor, so the present case is only the fifth case in the world. Despite the very poor prognosis of patients with pheochromocytoma and malignant peripheral nerve sheath tumors reported in the literature, the patient remains well without evidence of recurrence or new metastatic lesions at 36 months postoperatively.

Through August 2013, 105 cases of intracranial extraventricular neurocytoma (EVN) had been described; 6% were located in cerebellum and 22% were atypical EVN. A rare morphologic form of neurocytoma, atypical EVN has had only 24 cases reported to date. Its prognosis is poorer than the typical central neurocytoma. This case report describes an atypical cerebellar EVN, a form that has not been reported yet, hence the interest of this article. We emphasise its cystic nature and mural nodule, in an infrequent presentation. EVN are low-incidence tumours that we need to take into consideration when making the differential diagnosis of cystic cerebellar lesions with mural nodule. Given that the prognosis of atypical EVNs depends on the atypical nature and on the grade of resection, medical follow up has to be more constant, due to the greater degree of recurrence.

2017-07-01

In the last 30 years there were numerous model generated software systems offered targeting problems with the development productivity and the resulting software quality. CASE tools developed due today's date are being advertised as having "complete code-generation capabilities". Nowadays the Object Management Group (OMG) is calling similar arguments in regards to the Unified Modeling Language (UML) models at different levels of abstraction. It is being said that software development automation using CASE tools enables significant level of automation. Actual today's CASE tools are usually offering a combination of several features starting with a model editor and a model repository for a traditional ones and ending with code generator (that could be using a scripting or domain-specific (DSL) language), transformation tool to produce the new artifacts from the manually created and transformation definition editor to define new transformations for the most advanced ones. Present paper contains the results of CASE tool (mainly UML editors) comparison against the level of the automation they are offering.

Apatinib treatment combined with chemotherapy for advanced epithelial ovarian cancer: a case report.

PubMed

2017-01-01

Apatinib is a novel oral tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2, which has been proved by clinical trials to be effective and safe for patients with chemotherapy-refractory gastric cancer. To date, there is no study or case report on apatinib treatment for patients with ovarian cancer. Here, we present the case of a 50-year-old Chinese woman with advanced ovarian cancer, who received apatinib at a daily dose of 500 mg for 28 days per cycle after failure of fourth-line chemotherapy. Favorable oncologic outcome was achieved in this case after treatment with apatinib. The patient's progression-free survival is now 11.3 months, and she is taking apatinib and capecitabine as maintenance treatment. The common side effect of apatinib was fatigue; however, the toxicity of apatinib was controllable and tolerable. Thus, apatinib may be an option for chemotherapy-refractory advanced epithelial ovarian cancer, but this still warrants further investigation.
