    2016-01-01

    Dilation of the ascending aorta and aortic dissections are often seen in Marfan syndrome; however, true aneurysms of the subclavian and axillary arteries rarely seem to develop in patients who have this disease. We present the case of a 58-year-old man with Marfan syndrome who had undergone a Bentall procedure and thoracoabdominal aortic repair for an aortic dissection and who later developed multiple aneurysmal dilations of his right subclavian and axillary arteries. The aneurysms were successfully repaired by means of a surgical bypass technique in which a Dacron graft was placed between the carotid and brachial arteries. We also discuss our strategy for determining the optimal surgical approach in these patients. PMID:27777529

    Pericarditis in conjunction with nephritis is an uncommon clinical scenario with a broad differential diagnosis. We present the case of a 58-year-old male who developed nephritis and pericardial effusion with tamponade physiology. In the following, we discuss the differential diagnosis for concomitant nephritis and pericarditis and discuss the work-up performed on our patient. We also review the epidemiology of postinfectious glomerulonephritis in adults and describe previous cases of Streptococcus pyogenes pericarditis in the literature. PMID:27826373

    Cavitary pneumonia in immunocompromised patients is a challenging entity. Establishing accurate diagnosis and starting effective antibiotics are essential steps towards improving outcome. A 58-year-old stem cell transplant patient was admitted to the hospital with necrotizing pneumonia caused by nocardia. The disease progressed despite of aggrieve antimicrobial therapy. Nocardiosis continues to be a difficult disease to diagnose and treat. PMID:27872648

  4. The influence of maternal self-objectification, materialism and parenting style on potentially sexualized 'grown up' behaviours and appearance concerns in 5-8year old girls.

    There is widespread concern about young girls displaying 'grown up' or sexualized behaviours, as well as experiencing body image and appearance concerns that were previously thought to only impact much older girls. The present study examined the influence of three maternal attributes, self-objectification, materialism and parenting style, on sexualized behaviours and appearance concerns in young girls. A sample of 252 Australian mothers of 5-8year old girls reported on the behaviours and appearance concerns observed in their daughters and also completed measures of their own self-objectification, materialism and parenting style. It was found that a significant proportion of young girls were engaging with 'teen' culture, using beauty products and expressing some degree of appearance concern. Maternal self-objectification was related to daughters' engagement in teen culture, use of beauty products and appearance concern. Maternal materialism was related to girls' engagement in teen culture and appearance concern, while an authoritative parenting style was negatively related to girls' use of beauty products. The findings suggest that maternal self-objectification and materialism play a role in the body image and appearance concerns of young girls, and in so doing, identify these maternal attributes as novel potential targets for intervention.

    2014-06-01

    We report on a 58-year-old man who presented with simultaneous kappa-restricted chronic lymphocytic leukemia (CLL) and a lambda-restricted plasma cell dyscrasia causing AL amyloidosis involving the kidney and GI tract. While monoclonal immunoglobulins occasionally produced by CLL has previously been implicated in AL amyloidosis, this is the first case of AL amyloidosis resulting from a distinct plasma cell dyscrasia that is not clonally related to the concurrent CLL. Appropriate treatment depended on detailed pathologic diagnosis of both disease processes.

  9. Late-onset congestive heart failure in a patient with a 58-year-old huge traumatic carotid-jugular fistula and pseudoaneurysm: endovascular treatment with a stent-graft.

    PubMed

    2010-10-01

    We report a case of successful stent-graft endovascular treatment of a huge traumatic carotid-jugular fistula with a pseudoaneurysm that had resulted from a bullet injury. A 77-year-old man with a pulsatile neck mass came to our hospital complaining of dyspnea and chest pain at rest; about 58 years ago, a gunshot accident had inflicted a penetrating bullet wound on the right side of his neck. Computerized tomography angiogram had demonstrated a huge vascular mass protruding into the right anterior neck with a pseudoaneurysm. The calcified pseudoaneurysm had an oval-shaped opening in the right common carotid artery, with a large base into the right internal jugular vein. Echocardiography showed deteriorating congestive heart failure, wherein left ventricular (LV) enlargement with a LV end-diastolic diameter of 6.1 cm, severe tricuspid valve regurgitation, and LV ejection fraction of 60% was seen. The surgical approach was considered risky because of the severe deformity of the native vasculature, the severe calcified pseudoaneurysm, and the context of advanced age with congestive heart failure. Thus, we decided to treat this patient with endovascular devices. Fortunately, a stent-graft was delivered successfully across the carotid-jugular fistula and immediate follow-up angiogram demonstrated a small filling defect at the base of stent-graft representing thrombus. The follow-up computerized tomography angiograms obtained 2 weeks and 4 months later further demonstrated a patent stent-graft, no evidence of thrombus progression, and no abnormal shunt flow. The patient did not experience any neurologic complications nor did he show any evidence of pulmonary embolism for 8 months.

  10. A young man presenting with paralysis after vigorous exercise

    PubMed Central

    Gubran, Christopher; Narain, Rajay; Malik, Luqmaan; Saeed, Saad Aldeen

    2012-01-01

    Thyrotoxic periodic paralysis (TPP) is a rare metabolic disorder characterised by muscular weakness and paralysis in predisposed thyrotoxic patients. Although patients with TPP are almost uniformly men of Asian descent, cases have been reported in Caucasian and other ethnic populations. The rapid increase in ethnic diversity in Western and European nations has led to increase in TPP reports, where it was once considered exceedingly rare. Correcting the hypokalaemic and hyperthyroid state tends to reverse the paralysis. However, failure to recognise the condition may lead to delay in diagnosis and serious consequences including respiratory failure and death. We describe a young man who was diagnosed with hyperthyroidism who presented with acute paralysis. The clinical characteristics, pathophysiology and management of TTP are reviewed. PMID:22927268

  11. Data for the Reference Man: skeleton content of chemical elements.

    PubMed

    Zaichick, Vladimir

    2013-03-01

    This study was undertaken to provide reference values of chemical element mass fractions in intact bone of Reference (European Caucasian) Man/Woman. The rib bone samples investigated were obtained from autopsies of 84 apparently healthy 15-58-year-old citizens (38 females and 46 males) of a non-industrial region in the Central European part of Russia who had suffered sudden death. The mass fractions (mg/kg given on a wet mass basis) of 69 elements in these bone samples were measured by using neutron activation analysis with high-resolution spectrometry of short-lived and long-lived radionuclides, particle-induced gamma-ray emission, inductively coupled plasma atomic emission spectrometry, and inductively coupled plasma mass spectrometry including necessary quality control measures. Using published and measured data, mass fraction values of the 79 elements for the rib bone have been derived. Based on accepted rib to skeleton mass fractions and reference values of skeleton mass for Reference Man, the elemental burdens in the skeleton were estimated. These results may provide a representative bases for establishing related reference values for the Russian Reference Man/Woman and for revising and adding current reference values for the International Commission on Radiological Protection. The data presented will also be very valuable for many other applications in radiation protection, radiotherapy radiation dosimetry, and other scientific fields.

    2016-01-01

    Summary Clostridium perfringens bacteraemia is a potentially fatal condition, and its early identification is paramount to maximise chances of survival. Prompt recognition of intravascular haemolysis, a known complication of C. perfringens bacteraemia, can help guide clinical decision-making before microbiology data becomes available. We present a novel finding of severe hypertension in a fatal case of Clostridial bacteraemia with massive haemolysis. A 58-year-old man with no known medical history presented to the emergency department with malaise, fever and hypertension. He developed abdominal pain and a hepatic abscess was identified on CT imaging. Within 4 h of presentation, he developed massive intravascular haemolysis, extreme hypertension, pulmonary oedema and respiratory failure. He died less than 8 h after presentation. His blood cultures subsequently grew C. perfringens. This case underscores the importance of early recognition of intravascular haemolysis complicating C. perfringens bacteraemia, and discusses the rare complication of hypertensive emergency in this setting.

    2015-04-01

    Kaposi sarcoma (KS) is a malignant proliferation of endothelial cells within the skin. The clinical presentation is characterized by clusters of violaceous macules and papules that often appear on the distal extremities or trunk with or without oral mucosal involvement. Mucocutaneous lesions are present at onset of diagnosis in a minority of cases. The lesions can evolve to include the mucous membranes of the gastric mucosa and the lungs. We present a unique case of KS in a 45-year-old, asymptomatic, human immunodeficiency virus (HIV)-positive man with mucocutaneous involvement to highlight the importance of recognizing KS in immunocompromised patients.

    2016-01-01

    Limited data exist on the association between breast cancer treatments and coronary artery disease anatomy, particularly in males. We describe an unusual case of diffuse coronary ectasia in a man with breast cancer presenting with acute coronary syndrome (ACS). A 66-year-old man with breast cancer on paclitaxel, tamoxifen, and carboplatin chemotherapy regimen, presents with new onset chest pain. Electrocardiogram reveals anterolateral ST-segment depressions and elevated troponin I level. Emergent angiography revealed grossly ectatic coronary arteries with a total thrombotic occlusion of the mid right coronary artery. Serial intracoronary aspiration thrombectomy revealed fragments of red thrombus. Intracoronary tenectaplase was ultimately administered to restore perfusion. The patient clinically improved and warfarin was added to his cardiac regimen. Laboratory work up for connective tissue disease was negative. Although paclitaxel has been implicated in coronary artery neointima and media proliferation in the setting of drug-eluting stents, we believe our case is the first to describe massive coronary ectasia with significant thrombus burden requiring complex coronary intervention and thrombolysis in the setting of breast cancer therapy in a man.

    Russell-Silver syndrome (RSS) is a type of primordial dwarfism. Only one case of testicular cancer in RSS has been reported, the pathology of which was nonseminoma. Here, we report a case of seminoma in a 36-year-old man who was diagnosed with RSS at birth. The seminoma was diagnosed when the patient presented with testicular torsion. This is the first report of testicular seminoma in an RSS patient in the literature. We also discussed the correlation between seminoma and RSS. PMID:27034882

  18. Stroke as the presenting feature of new onset diabetes in a young man.

    Jones, Ruth; McMurray, Emily; Robinson, Oliver

    2014-06-25

    A 34-year-old man presented to a hospital with a 7-day history of nausea, vertigo, ataxia and frontal headache. Examination revealed ipsilateral cerebellar signs. CT of the brain demonstrated left cerebellar hypodensity suggestive of ischaemic stroke or space occupying lesion. Full blood count showed a markedly raised haemoglobin (219 g/L) and haematocrit (0.56). Admission urinalysis was performed but the results not reviewed. Owing to patient deterioration, an arterial blood gas was performed. This showed profound metabolic acidosis. Repeat urinalysis was positive for glucose and ketones. MRI of the brain confirmed ischaemic stroke. The underlying cause of this was hyperviscosity secondary to relative polycythaemia, resulting from undiagnosed diabetic ketoacidosis as a first presentation of diabetes. This case report highlights ischaemic stroke as an unusual presenting feature of diabetic ketoacidosis. Notably, the underlying diagnosis of diabetic ketoacidosis was initially missed, thereby emphasising the importance of performing an admission urinalysis and acting on the results.

    2014-04-01

    Acute intermittent porphyria, the most common porphyria affecting the nervous system, typically presents with neurovisceral crises followed by a motor neuropathy. We describe a 23-year-old black South African man presenting with a progressive stuttering, lower motor neuron syndrome developing over months. He had not experienced pain or neuropsychiatric symptoms. One year after symptom onset he was bed-bound with a flaccid quadriparesis. There was marked amyotrophy, but without fasciculations. Sensation was intact apart from a hypo-aesthetic patch over the thigh. Electrophysiological investigations showed an active motor axonopathy. Urinary porphyrins, delta-aminolaevulinic acid and porphobilinogen were elevated. Mutation analysis revealed the c445C>T (R149X) mutation in the porphobilinogen deaminase gene. The patient responded dramatically to haem arginate and could walk with assistance 2 weeks later. We identified the first molecularly confirmed acute intermittent porphyria in a black South African. The clinical presentation mimicked a progressive lower motor neuron syndrome.

    2015-01-01

    Patients with cat-scratch disease (CSD), which is caused by Bartonella henselae, typically present with local lymphadenopathy with a brief period of fever and general symptoms. Most cases are self-limiting and usually afflict children and young adults. Although rare, CSD can lead to serious complications, especially in immunocompromised patients. These rare complications often require intensive treatment. We describe the case of a 79-year-old man who presented with general malaise and a high fever. The physical examination findings were unremarkable. Of note, the lymph nodes were not enlarged. An abdominal CT scan with intravenous contrast revealed a solitary splenic abscess and no lymphadenopathy. The initial antibiotic treatment was ineffective and a splenectomy was indicated. A history of contact with cats raised the possibility of CSD, which was confirmed by a positive serology test result for B henselae. Antibiotic treatment with azithromycin successfully treated the splenic abscess and splenectomy was avoided. PMID:25804947

    A 29-year-old man with a history of oculocutaneous albinism presented to the ED complaining of progressive dyspnea on exertion. One month prior to admission, the patient had begun to experience worsening dyspnea provoked by routine household activities. Additionally, he had developed a nonproductive cough, exacerbated by cold weather. He denied associated chest pain, hemoptysis, fever, chills, or night sweats. He denied any new exposures or sick contacts in the recent past. A review of systems was significant for a history of epistaxis and frequent bruising. Born in Honduras, he had immigrated to the United States approximately 10 years prior to his presentation to our facility. Furthermore, there was no family history of albinism, bleeding disorders, or pulmonary disease.

    We present the clinical, electrophysiological and molecular genetic findings of a 58-year-old male with genetically confirmed Huntington's disease (HD) and concurrent clinically definite ALS by El Escorial criteria. The patient presented with asymmetric upper limb amyotrophy and weakness, and subsequently developed chorea and cognitive change. Genetic testing confirmed the presence of expanded trinucleotide repeats in huntingtin, consistent with a diagnosis of Huntington's disease. This case confirms the rare coexistence of Huntington's disease and motor neuron degeneration.

  5. ANA-Negative Presentation of SLE in Man with Severe Autoimmune Neutropenia

    PubMed Central

    2016-01-01

    Background. Systemic lupus erythematosus (SLE) is a chronic, inflammatory, connective tissue disease that commonly affects the joints and a variety of organs due to an overactivation of the body's immune system. There is wide heterogeneity in presentation of SLE patients, including lung, central nervous system, skin, kidney, and hematologic manifestations. Case Presentation. We report a case of atypical manifestation of SLE in a 53-year-old man who presented with neutropenic fever. Physical findings of interest included oral ulcers on the lower lip, a malar-like rash across the bridge of the nose, and a discoid-like rash on extensor surfaces of the elbows and knees. Labs include ANC <100, weakly positive anti-dsDNA, negative ANA, ferritin 1237 ng/mL, low C3/C4, and positive direct Coombs' test. A thorough workup for infection and hematologic malignancy was negative. Two days after initiation of therapy with 25 mg IV solumedrol twice a day, the patient's daily fevers resolved. ANC drastically improved to 2000 after two weeks of steroid treatment. He was later found to have a high titer of anti-neutrophil antibodies. Discussion. Autoimmune leukopenia is a common presentation in SLE, occurring in 50–60% of patients. Severe autoimmune neutropenia is uncommon and may correlate with high anti-neutrophil antibody activity despite a negative ANA. As neutropenia is usually mild, there are currently no guidelines for therapy. For our patient, we started him on low dose IV solumedrol and found that he responded drastically to treatment. Given strongly positive nonspecific anti-neutrophil antibodies in the setting of a negative ANA noted in our patient, it is likely that there are other currently unknown antibodies associated with SLE which may correlate strongly with autoimmune neutropenia.

    The authors describe a case of aneurysmal subarachnoid haemorrhage in a 53-year-old man with background of osteogenesis imperfecta (OI). CT brain revealed diffuse subarachnoid haemorrhage (SAH) and cerebral angiogram subsequently confirmed vertebral artery aneurysm rupture leading to SAH. To the authors knowledge this is the first case of vertebral artery aneurysmal SAH described in OI. A previously undiagnosed OI was confirmed by genetic analysis (COL1A1 gene mutation). This aneurysm was successfully treated by endovascular route. Post interventional treatment patient developed stroke secondary to vasospasm. Communicating hydrocephalus, which developed in the process of management, was successfully treated with ventriculo-peritoneal shunt. The aetio-pathogenesis and management of this condition is described. The authors have reviewed the literature and genetic basis of this disease. PMID:22674700

    Atypical presentation of emergency abdominal aortic aneurysm comprises a wide spectrum of symptoms. Lower limbs' involvement is infrequent, usually monolateral and with clear vascular features. We report the case of a 58-year-old patient who complained exclusively about symmetric lower limb myalgias without vascular features, after having repeatedly climbed the stairs of the school he worked in. The surprising final diagnosis was of rupturing abdominal aortic aneurysm; the patient was sent to emergency surgery and survived.

    We report a case of a chronic infiltrate of the intestinal wall of the transverse colon by the eggs of Enterobius vermicularis in a man who had immigrated to Taiwan from mainland China 50 years ago. During surgery for suspected transverse colon carcinoma, histologic examination of the tumor mass revealed eggs of E. vermicularis embedded in granulation tissue in the submucosa of the transverse colon. Results of a stool examination were negative for eggs but strongly positive for occult blood. The mass in the transverse colon was completely removed during surgery. At the present time, the patient remains asymptomatic.

    2010-01-01

    Background Primary squamous cell carcinomas of the colorectum are very uncommon. Until now, to the best of our knowledge, only 114 cases of squamous cell carcinoma in the colorectum exist in the reported literature. Here we report a case of squamous cell carcinoma of the rectum in the ethnic Kashmiri population in northern India. Case Presentation The case of a 60-year-old male patient (Asian) with a pure squamous cell carcinoma of the rectum is presented here. The patient underwent a curative surgery with concomitant chemotherapy. Two years after the initial curative resection of the tumor he is still alive. Conclusion The prognosis for squamous cell carcinoma of the colorectum is worse than for that of adenocarcinoma, because of the delayed diagnosis. The etiopathogenicity of squamous cell carcinoma of the colorectum is discussed. Surgical resection of the lesion seems to be the treatment of choice. Chemotherapy also helps in improvement of the prognosis. PMID:21118539

    We present the case of a non-alcoholic man, who, following severe malnutrition, presented with dysphagia that necessitated gastrostomy tube placement. The patient subsequently developed encephalopathy, at which point thiamine deficiency was suspected and thiamine supplementation initiated. The encephalopathy and the dysphagia resolved, but the patient was left with a dense amnestic deficit consistent with Korsakoff syndrome. MRI at the time of the encephalopathy revealed lesions consistent with Wernicke-Korsakoff syndrome. This case represents a remarkable example of Wernicke-Korsakoff syndrome that for a prolonged time period had as its sole manifestation severe dysphagia. To our knowledge, there is only one similar case reported in the literature. This case serves to alert neurologists that isolated dysphagia may be the presenting symptom of this classic neurological syndrome even in the absence of alcoholism.

    Hereditary haemochromatosis is a multisystem disorder of iron metabolism. Hepatic manifestations include hepatomegaly, cirrhosis and hepatocellular carcinoma. Hepatocellular carcinoma is almost always preceded by cirrhosis. We present a case of an 83-year-old man without history of liver disease or iron overload who presented with abdominal pain. Workup revealed mildly elevated transaminases, ferritin of 3996 and a solitary liver tumour. Biopsy was consistent with hepatocellular carcinoma in a background of haemosiderosis without cirrhosis. He was diagnosed with hereditary haemochromatosis and hepatocellular carcinoma. He underwent a partial hepatectomy and was started on routine phlebotomy and surveillance imaging. He has improved and has not had signs of recurrence or new complications of haemochromatosis. We suggest a possible reason for his unique and late presentation.

    Schwannomas are slow-growing tumors with symptoms manifesting progressively. We report the case of a patient who manifested a sudden loss of consciousness as clinical presentation of an intracranial schwannoma with no acute hemorrhage or hydrocephalus. A 30-year-old male presented comatose and posturing. Cerebral CT revealed an extra-axial lesion with a heterogeneous enhancement and a cystic component located on the right cerebellopontine angle (CPA), displacing the brain stem. No acute hemorrhage or hydrocephalus was documented. Through a retrosigmoid suboccipital craniotomy, an extended subtotal tumor resection was performed. The patient experienced no functional hearing impairment and resumed his daily-life activities 3 months after surgery. Histopathological examination was compatible with a benign schwannoma. An exuberant lymphoplasmacytic infiltrate was found in many areas, signing the presence of an unusual inflammatory reaction with adjacent important intratumoral edema. We propose that the exuberant inflammatory infiltrate and the associated intratumoral edema acted as determining elements in the increase of mass effect and sudden clinical deterioration.

    Progressive supranuclear palsy (PSP) is a neurodegenerative disorder with diverse clinical phenotypes characterized by supranuclear gaze palsy, parkinsonism with postural instability, and frontal dementia. The early and accurate diagnosis of PSP remains difficult because of the variable combination of symptoms and frequent lack of gaze abnormalities early in the disease course. Moreover, a subset of PSP shows behavioral changes as the initial presentation, which considerably overlaps with the clinical picture of frontotemporal dementia (FTD). Thus, this subgroup possibly needs psychiatric assessments. Here, we describe a clinical case of PSP difficult to differentiate from FTD because the frontal presentation persisted without gaze palsy until the late stage of the clinical course. A 58-year-old man was admitted to our hospital for the reconsideration of a diagnosis of FTD. Disinhibited and gambling behaviors inconsistent with his previous personality first appeared at around the age of 45, with gradual progression, followed by memory deficits, executive dysfunction, and a slowing of mental processes. Recurrent sexual disinhibition led him to undergo psychiatric consultation at the age of 57. Downward gaze palsy and postural instability with recurrent falls emerged 8 months after the first psychiatric examination, and he was clinically diagnosed with PSP 13 years after the initial frontal presentation. PSP should be considered in the differential diagnosis of patients presenting with frontal lobe symptoms, even in psychiatric practice.

    A 30-year-old man attended the emergency department with a 4-day history of progressive, bilateral upper limb weakness. He had mild shortness of breath and occasional swallowing difficulties. One month prior to presentation, he had flu-like symptoms and diarrhoea. Examination revealed upper limb hypotonia, symmetrical distal arm weakness and hyporeflexia. Power and reflexes in the lower limbs were normal. Nerve conduction studies and lumbar puncture demonstrated features consistent with Guillain-Barré syndrome (GBS). The patient was treated with a 5-day course of intravenous immunoglobulins. He improved significantly over the next 2 weeks. Breathing and swallow function did not deteriorate and required no further intervention. He had a sustained improvement, and remained at baseline 1 year later. Work-up for underlying structural, infectious, inflammatory and paraneoplastic aetiologies were negative. Serum antiganglioside antibodies were positive for the anti-GT1a IgG isotype supporting the clinical diagnosis of the pharyngeal-cervical-brachial variant of GBS.

    We are reporting a case of familial thoracic aortic aneurysm and dissection in a 26-year-old man with no significant past medical history and a family history of dissecting aortic aneurysm in his mother at the age of 40. The patient presented with cough, shortness of breath, and chest pain. Chest X-ray showed bilateral pulmonary infiltrates. CT scan of the chest showed a dissection of the ascending aorta. The patient underwent aortic dissection repair and three months later he returned to our hospital with new complaints of back pain. CT angiography showed a new aortic dissection extending from the left carotid artery through the bifurcation and into the iliac arteries. The patient underwent replacement of the aortic root, ascending aorta, total aortic arch, and aortic valve. The patient recovered well postoperatively. Genetic studies of the patient and his children revealed no mutations in ACTA2, TGFBR1, TGFBR2, TGFB2, MYH11, MYLK, SMAD3, or FBN1. This case report focuses on a patient with familial TAAD and discusses the associated genetic loci and available screening methods. It is important to recognize potential cases of familial TAAD and understand the available screening methods since early diagnosis allows appropriate management of risk factors and treatment when necessary.

    Prolonged bisphosphonate use has been associated with increased risk of atypical femoral fractures. Very few cases of atypical femoral fractures have been reported with denosumab. We report a case of bilateral tibial stress reactions in a 60-year-old man with no history of osteoporosis who was on prolonged high-dose denosumab for the treatment of giant cell tumor of bone. He presented with a 3-month history of pain in his bilateral shins worsening with activity and improving with rest. Although initial radiographs were unremarkable, he was found to have changes consistent with a stress reaction on magnetic resonance imaging of the distal tibia. To our knowledge, bilateral tibial stress reactions have not been previously reported with anti-resorptive therapies (neither bisphosphonates nor denosumab). Our case is intriguing in terms of the development of stress reactions as a precursor to stress fractures which may also relate to atypical fractures. Our case suggests a possible association between denosumab use and stress reactions. Of note the indication for denosumab in our case was for the treatment of giant cell tumor of bone where the Food and Drug Administration (FDA) approved dose is substantially higher than the FDA approved dose for osteoporosis treatment. Although rare, clinicians should consider the possibility of stress fractures in patients on anti-resorptive medications such as denosumab, especially when a patient presents with new onset thigh pain, hip pain or pain over an area affecting the long bones. Evaluation by imaging of affected areas should be pursued to enable early detection and intervention, as well as prevention of morbidity and associated ongoing risk to the patient.

    We report a 58-year-old man showing spastic paraparesis due to medulla oblongata compression by tortuous vertebral arteries. He noticed weakness of both legs and gait disturbance at the age of 58 years and his symptoms progressively worsened during the following several months. General physical findings were normal. Blood pressure was normal and there were no signs of arteriosclerosis. Neurological examination on admission revealed lower-limb-dominant spasticity in all four extremities, lower-limb weakness, hyperreflexia in all extremities with positive Wartenberg's, Babinski's and Chaddock's signs, mild hypesthesia and hypopallesthesia in both lower limbs, and spastic gait. Cranial nerves were all normal. Serum was negative for antibodies against human T-cell lymphotropic virus-1 antibody. Nerve conduction and needle electromyographic studies of all four limbs revealed normal findings. Cervical, thoracic and lumbo-sacral magnetic resonance imaging (MRI) findings were all normal. Brain MRI and magnetic resonance angiography demonstrated bilateral tortuous vertebral arteries compressing the medulla oblongata. Neurovascular decompression of the right vertebral artery was performed because compression of the right side was more severe than that of the left side. Post-operative MRI revealed outward translocation of the right vertebral artery and relieved compression of the medulla oblongata on the right side. The patient's symptoms and neurological findings improved gradually after the operation. Bilateral pyramidal tract signs without cranial nerve dysfunction due to compression of the medulla oblongata by tortuous vertebral arteries are extremely rare and clinically indistinguishable from hereditary spastic paraplegia (HSP). Although we did not perform a genetic test for HSP, we consider that the spastic paraparesis and mild lower-limb hypesthesia were caused by compression of the medulla oblongata by bilateral tortuous vertebral arteries based on the post

    Metastatic ovarian cancer uncommonly presents with skin metastasis. When present, skin metastases of ovarian cancer are usually localized in the vicinity of the primary tumor. We report a case of a 58-year-old woman with a rapid growing erythematous, well-defined nodule localized on the left nasal ala. A skin biopsy was performed and histopathological and immunohistochemical findings were compatible with a cutaneous metastasis of adenocarcinoma. A systematic investigation revealed a bilateral ovarian cystadenocarcinoma associated with visceral dissemination, likely associated with nose cutaneous metastasis. We report a very uncommon case because of the presentation of ovarian carcinoma as cutaneous metastasis. To our knowledge, this atypical localization on the nose has not been described yet in the literature. PMID:28300910

    We describe the case of a 23-year-old man presenting with recurrent pleuritic chest pain and prolonged fever after electrophysiology testing and placement of an implantable cardioverter-defibrillator because of a suspected arrhythmogenic right ventricular dysplasia. The clinical suspicion was initially directed toward pneumonia with pleural effusion and later toward an infection of the cardiac device complicated by septic pulmonary embolism. The definitive diagnosis of pulmonary embolism and infarction was suggested by a point-of-care thoracic sonography, performed at the bedside by a clinician caring for the patient, and then confirmed by contrast enhanced computed tomography, which also showed thrombosis of the left iliofemoral vein, site of percutaneous puncture for cardiac catheterization. Prolonged fever was attributable to a concomitant Epstein-Barr virus primary infection that acted as confounding factor. The present report confirms the value of bedside thoracic sonography in the diagnostic evaluation of patients with nonspecific respiratory symptoms. PMID:26576159

    Serotonin syndrome (SS) is a potentially life-threatening condition resulting from excessive central and peripheral serotonergic activity. Clinically, it is a triad of mental-status changes, neuromuscular abnormalities, and autonomic disturbances. It can be caused by intentional self-poisoning, overdose, or inadvertent drug interactions. We report the case of a 58-year-old male with type 2 diabetes mellitus and obsessive compulsive disorder who developed pulmonary edema as a possible complication of SS. SS was caused by a combination of three specific serotonin re-uptake inhibitors (fluoxetine, fluvoxamine, and sertraline), linezolid, and fentanyl. The hospital course was further complicated by difficult weaning from the ventilator. SS was identified and successfully treated with cyproheptadine and lorazepam. The case highlights the importance of effective consultation-liaison and prompt recognition of SS as the presentation may be complex in the presence of co-morbid medical illness. PMID:26997733

    Extramedullary plasmacytoma (EMP) is a plasma cell neoplasm without bone marrow involvement or other systemic characteristics of multiple myeloma. Few large-scale clinical studies have been conducted because of the rarity of EMP, especially when it arises from the mediastinum. Herein we report a rare case of solitary mediastinal plasmacytoma with reactive pleural effusion. A 58-year-old female presented with grade 4 dyspnea and dysphagia, with a mediastinal mass observed with on PET. CT-guided biopsy results were suggestive of IgG kappa-type EMP arising from the anterior mediastinum. The patient was treated with local radiotherapy to the mediastinum, and had clinical and radiological response s were good. Radiotherapy is an effective treatment for mediastinal EMP, but a complete workup is mandatory, including PET, as the majority of such masses coexist with multiple myeloma.

    A 58-year-old immunocompetent man gradually developed loss of appetite, cognitive decline, gait disturbances, and personality changes over 4 months. Brain magnetic resonance imaging (MRI) revealed bilateral diffuse leukoencephalopathy without mass formation on admission. His condition progressively deteriorated, and we treated him with intravenous high-dose steroids. His symptoms improved rapidly, but exacerbated when therapy was withdrawn. A brain biopsy was performed, and the diagnosis of primary central nervous system lymphoma (PCNSL) was confirmed. He was successfully treated with high-dose methotrexate therapy. Although it is difficult to diagnose PCNSL without mass formation in the early stages, steroid responsiveness is important and brain biopsy is essential for the correct diagnosis of PCNSL.

We report a patient with an atypical presentation of NMS. A 60-year-old man with schizophrenia was admitted to our hospital with disturbed consciousness, fever and marked extrapyramidal rigidity both in the upper and lower extremities. He had been given i.m. zuclopenthixol 200 mg/month but had not taken the last dose. Laboratory investigations showed that creatinine phosphokinase 428 IU/l (normal up to 130), lactate dehydrogenase 772 IU/l (normal up to 450), blood glucose 256 mg/dl (65-110). Urine analyses revealed ketonuria. White blood cell (WBC) count was 6100 cells/mm(3). Therefore, the patient was diagnosed as having NMS and antipsychotic medications were stopped. Adequate hydration was provided and bromocryptine 5 mg was started three times a day. Despite treatment, the patient died due to acute myocardial infarction after 3 days of hospitalization.

    2012-01-01

    Introduction Campylobacter is an important causative agent of intestinal infections in humans. Bacteremia is detected in less than 1% of patients, mainly in immunocompromised patients and in extreme age groups. Cellulitis is a relatively common manifestation of Campylobacter infection, but concomitant bacteremia is a rare event. Infections of the pacemaker area are caused primarily by staphylococci, followed by fungi, streptococci and Gram-negative rods. To the best of our knowledge, this is the first case report of pacemaker pocket infection and bacteremia caused by Campylobacter fetus. Case presentation A 72-year-old Croatian Caucasian man with myelodysplasia, impaired fasting glucose levels and a recently implanted permanent pacemaker was admitted to hospital after six days of fever, development of red swelling of the pacemaker pocket area and worsening of his general condition. No antibiotic therapy was introduced in the outpatient setting. He denied any recent gastrointestinal disturbances. With the exception of an elevated leukocyte count, erythrocyte sedimentation rate, and C-reactive protein and blood glucose levels, other laboratory findings were normal. Treatment with vancomycin plus netilmicin was introduced, and a surgical incision with drainage of the pacemaker pocket was performed. The entire pacemaker system was removed and a new one re-implanted after 14 days of antibiotic therapy. Transesophageal echocardiography showed no pathological findings. Three subsequent blood cultures obtained on admission as well as swab culture of the incised pacemaker area revealed Campylobacter fetus; stool and pacemaker lead cultures were negative. According to the microbiological results, antibiotic therapy was changed to ciprofloxacin plus netilmicin. A clinical examination and the results of a laboratory analysis performed after two weeks of therapy were within normal limits. Conclusion Myelodysplasia, impaired fasting glucose levels and older age could be

    Thromboembolism and atherosclerotic stenosis both can cause arterial occlusion. Aortoiliac occlusive disease involving bifurcation of the aortoiliac artery induces symptoms of ischemia such as claudication and pain of buttocks and thighs, decreased bilateral femoral pulses, and impotence. Here, we describe a 58-year-old woman with a past history of atrial fibrillation and lacuna stroke with minimal right side weakness. She presented to our emergency department with sudden onset bilateral pain in the legs and paraplegia. A comprehensive examination revealed paresthesia and decreasing bilateral distal pulses. Computed tomographic imaging showed filling defects over the low abdominal aorta just above the bifurcation of the common iliac artery and bilateral femoral arteries. Acute aortic embolic occlusion was suspected. Her symptoms were resolved after emergent thrombectomy for acute limb ischemia. Physicians need to be aware of aortoiliac embolic occlusive disease which may present as acute paraplegia.

However, many still celebrate Von Braun, who died in 1977, as the man who put the astronauts on the Moon. While this is not strictly true, there is no doubt that Von Braun was one of the most influential engineers, lobbyists and personalities in the Moon-landing project.

    Asterixis is not yet considered a common neurological sign of cerebellum infarction, and the pathogenic mechanism for asterixis remains elusive. We report a 58-year-old male with moderate hypertension who presented to our emergency department for acute headache in both cervical and occipital regions of the left side. About 2 hours later the patient developed ipsilateral asterixis in the upper left limb; 3 days later the asterixis disappeared. Magnetic resonance imaging of the brain disclosed cerebellar infarctions at the left superior cerebellar artery. In conclusion, we observed that a transitory asterixis associated with ipsilateral headache can be an initial clinical manifestation of ipsilateral cerebellar infarctions in the superior cerebellar artery area.

    Introduction Staphylococcus hyicus is a coagulase-variable Staphylococcus spp. well-known by veterinarians since it is the major agent of a severe cutaneous infection in piglets called exudative epidermitis. In other species the symptoms of infection are quite different. Human cases are uncommon but seem to occur more frequently after repeated contacts with farm animals. Case report We report the case of a 58-year-old man suffering from debilitating subacute lumbar pain, in whom diagnosis of infectious spondylodiscitis was based on spine MRI and positive microbiological results. A strain of S. hyicus was surprisingly isolated from blood cultures and bone biopsy. Identification was confirmed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS, Bruker, USA), and the patient was successfully cured with a six-week course of anti-staphylococcal antibiotic regimen. Conclusion The prevalence of S. hyicus in human clinical samples is very low, but may be underestimated. This pathogen may enter the bloodstream through a skin injury, and then induce various pyogenic manifestations in people working with farm animals. S. hyicus exfoliative toxins, responsible for dermatological lesions in piglets, seem unable to damage the human epidermis, explaining the absence of cutaneous blisters in the previously reported cases. Precise data about its pathogenicity in humans and the adequate therapy are lacking. PMID:27622163

  8. Remeasuring man.

    Weisberg, Michael

    2014-05-01

    Samuel George Morton (1799-1851) was the most highly regarded American scientist of the early and middle 19th century. Thanks largely to Stephen Jay Gould's book The Mismeasure of Man, Morton's cranial capacity measurements of different races is now held up as a prime example of and cautionary tale against scientific racism. A team of anthropologists recently reevaluated Morton's work and argued that it was Gould, not Morton, who was biased in his analysis. This article is a reexamination of the Morton and Gould controversy. It argues that most of Gould's arguments against Morton are sound. Although Gould made some errors and overstated his case in a number of places, he provided prima facia evidence, as yet unrefuted, that Morton did indeed mismeasure his skulls in ways that conformed to 19th century racial biases. Gould's critique of Morton ought to remain as an illustration of implicit bias in science.

    With an increasing pandemic of HIV/AIDS, the incidence of HIV-associated lymphoma is expected to rise. Here, the authors report a case of a 41-year-old man who presented with right upper quadrant pain and mass, and was subsequently diagnosed with HIV-associated diffuse large B cell lymphoma (DLBCL) with cardiac involvement. This case illustrates some of the uncommon and interesting aspects of DLBCL: primary extramedullary extranodal stage IV disease as the presenting feature; cardiac involvement at presentation; DLBCL as the only clue to the diagnosis of HIV; and management of HIV-associated DLBCL. This case is also a reminder of the importance of the routine HIV screening for all patients between the ages of 13-64 years, as advocated by centres of disease control and prevention.

    Cnidarian envenomations are common occurrences in the tropics that can affect holidaymakers. The cutaneous reactions are classified as immediate or delayed types. Delayed allergic reactions are persistently recurring dermatitis, which can occur within 1-4 weeks from the initial sting, and may last for several months. Hypertrophic scar-like or keloid-like reactions are rare, and are believed to be a type IV hypersensitivity reaction to sequestered antigens from stinging filaments. We report an unusual case of delayed allergic dermatitis with keloid-like presentation caused by Physalia utriculus.

    A 58 year old female attended our A&E department following a fall in the garden with swelling and bruising of the right arm and the elbow. Anteroposterior and lateral radiographs were interpreted as showing a normal elbow joint. A diagnosis of soft tissue injury to the elbow was made and the patient was discharged with advice. She returned 2 days later, did not have an x ray, and again given advice. Three weeks later she was referred back to A&E by the general practitioner with persistent swelling of the elbow. Further radiographs showed a posterolateral dislocation of the elbow. The elbow was reduced under sedation but was subsequently dislocated at follow up, and was treated by external fixator and transolecranon pin. The fixator was removed at 4 weeks and the elbow was then stable. This case highlights that recurrent elbow dislocations due to significant ligament injuries can present in joint and subsequently dislocate. A high index of suspicion is necessary and appropriate referral to the specialist must be made to avoid the morbidity associated with recurrent dislocation. It also emphasises the need to always assess the patient on his or her own merits despite previously normal investigations.

    Introduction: Tuberculosis tenosynovitis of the wrist and hand is an unusual condition. It mimics a number of other clinical conditions such as ganglion, De quervan’s disease, carpal tunnel syndrome, granulomatous gout, neurofibroma, and haemangioma. Case Report: We present case of 58-year-old male patient with swelling over thenar region of left hand where the initial fine needle aspiration cytology (FNAC) report suggested diagnosis of ganglion/synovial cyst, but the patient did not improve with conservative treatment. FNAC was repeated which showed granulomatous inflammation consistent with the clinical diagnosis of tuberculosis and antitubercular therapy for 9 months was given. Swelling disappeared and normal range of movements was attained in adjacent joints at final follow-up of 12 months from initiation of antitubercular treatment (ATT). Conclusion: The literature on the management of tubercular tenosynovitis has mostly incorporated surgical method as one of the first-line treatments. We report an unusual case, where the tenosynovitis of wrist completely responded within 12 months of ATT without any need of surgical treatment. PMID:28164057

    Glucose phosphate isomerase (GPI, glucose 6-phosphate ketol-isomerase, EC 5.3.1.9) is a housekeeping gene expressed in all tissues and organisms that utilize glycolysis and gluconeogenesis. Deficiency in humans leads to a rare form of nonspherocytic hemolytic anemia. The authors have isolated a 3.2-kb mouse cDNA containing glucose phosphate isomerase coding sequence and a 2.1-kb intronic sequence and a large proportion of the human gene (approaching 55 kb) in four phage [lambda] recombinants. A 4-kb intronic fragment from the human gene showing homology to the mouse intronic sequence has been isolated and sequenced. The fragment contains approximately 1.5 kb of sequence that is composited of 30 repeat units of a novel 50-kb tandemly repeated unit. The mouse intronic sequence contains 18 similar units. The human consensus sequence differs from the mouse consensus sequence at only 7 positions out of 50 (positions 16, 26, 27, 42, 43, 47, and 48). A probe containing the repeat element detects polymorphisms, specific to glucose phosphate isomerase, in human DNA. The repeat element does not appear to be present at any other loci in human DNA. The conservation of this intronic repeat element extends to pig and Chinese hamster. 26 refs., 4 figs.

    The potential costs of several options of a manned Mars mission are examined. A cost estimating methodology based primarily on existing Marshall Space Flight Center (MSFC) parametric cost models is summarized. These models include the MSFC Space Station Cost Model and the MSFC Launch Vehicle Cost Model as well as other modes and techniques. The ground rules and assumptions of the cost estimating methodology are discussed and cost estimates presented for six potential mission options which were studied. The estimated manned Mars mission costs are compared to the cost of the somewhat analogous Apollo Program cost after normalizing the Apollo cost to the environment and ground rules of the manned Mars missions. It is concluded that a manned Mars mission, as currently defined, could be accomplished for under $30 billion in 1985 dollars excluding launch vehicle development and mission operations.

    Introduction. Bilateral vocal cord paralysis (BVCP) is a potential medical emergency. The Otolaryngologist plays a crucial role in the diagnosis and management of BVCP and must consider a broad differential diagnosis. We present a rare case of BVCP secondary to anti-Hu paraneoplastic syndrome. Case Presentation. A 58-year-old female presented to an Otolaryngology clinic with a history of progressive hoarseness and dysphagia. Flexible nasolaryngoscopy demonstrated BVCP. Cross-sectional imaging of the brain and vagus nerves was negative. An antiparaneoplastic antibody panel was positive for anti-Hu antibodies. This led to an endobronchial biopsy of a paratracheal lymph node, which confirmed the diagnosis of small cell lung cancer. Conclusion. Paraneoplastic neuropathy is a rare cause of BVCP and should be considered when more common pathologies are ruled out. This is the second reported case of BVCP as a presenting symptom of paraneoplastic syndrome secondary to small cell lung cancer. PMID:27668114

    A viable power system technology for a surface transportation vehicle to explore the planet Mars is presented. A number of power traction systems were investigated, and it was found that a regenerative hydrogen-oxygen fuel cell appears to be attractive for a manned Mars rover application. Mission requirements were obtained from the Manned Mars Mission Working Group. Power systems weights, power, and reactants requirements were determined as a function of vehicle weights for vehicles weighing from 6,000 to 16,000 lb (2,722 to 7,257 kg), (Earth weight). The vehicle performance requirements were: velocity, 10 km/hr; range, 100 km; slope climbing capability, 30 deg uphill for 50 km; mission duration, 5 days; and crew, 5. Power requirements for the operation of scientific equipment and support system capabilities were also specified and included in this study. The concept developed here would also be applicable to a Lunar based vehicle for Lunar exploration. The reduced gravity on the Lunar surface, (over that on the Martian surface), would result in an increased range or capability over that of the Mars vehicle since many of the power and energy requirements for the vehicle are gravity dependent.

    Man's ability to live and perform useful work in space was demonstrated throughout the history of manned space flight. Current planning envisions a multi-functional space station. Man's unique abilities to respond to the unforeseen and to operate at a level of complexity exceeding any reasonable amount of previous planning distinguish him from present day machines. His limitations, however, include his inherent inability to survive without protection, his limited strength, and his propensity to make mistakes when performing repetitive and monotonous tasks. By contrast, an automated system does routine and delicate tasks, exerts force smoothly and precisely, stores, and recalls large amounts of data, and performs deductive reasoning while maintaining a relative insensitivity to the environment. The establishment of a permanent presence of man in space demands that man and machines be appropriately combined in spaceborne systems. To achieve this optimal combination, research is needed in such diverse fields as artificial intelligence, robotics, behavioral psychology, economics, and human factors engineering.

    Fewer than 20 patients with lymphocytic adenohypophysitis have been reported, all of them women, and it usually occurs during pregnancy or the postpartum period. We report the recognition of lymphocytic adenohypophysitis in a man. The patient presented with anterior hypopituitarism and an intrasellar mass on computed tomography. Antipituitary antibodies, found in only one of the previous patients, were not present in this man, although low titer antinuclear antibodies were found. The implications of this latter finding are unclear. The patient's histocompatibility antigen (HLA) types were A2, B8, Bw58, DR1, and DR5. The degree of pituitary failure seemed out of proportion to the size of the mass seen on computed tomographic scan.

The capabilities of the interactive software package being presently developed by the SRS for the mission/program analysis are described, and it is shown that the interactive package can be used to investigate the impact of various mission concepts on the sensitivity of mass required in LEO, schedules, relative costs, and risk. The results, to date, indicate the need for an earth-to-orbit transportation system much larger than the present STS, reliable long-life support systems, and either advanced propulsion or aerobraking technology.

    2016-01-01

    Light in the form of solar radiation influenced early civilisations and resulted in the independent development of a number of sun-worshipping dieties. These were of particular importance as hunter gatherers transformed into settled agricultural societies. All artificial light sources were synonymous with fire, and early civilisations began to expand their visual day by burning brands, oil, and candles. Fire-based light sources extended for thousands of years and were still present in the era of gas lighting. Light meant fire risk. The advent of incandescent bulbs and the era of electric lighting really only expanded in the early part of the twentieth century. Fluorescent lighting became available in the 1940s, and today the drive for low energy has resulted in a plethora of novel light sources—in particular, light-emitting diodes (LEDs). Evolution governed the development of the eye in relation to roughly 12 h of light gradually changing to 12 h of darkness. Today almost daylight levels can be achieved abruptly at the flick of a switch. Many studies have demonstrated the spectral dependence of eye health, with the retinal hazard zone associated with wavelengths in the blue, peaking at 441 nm— many of today's low-energy sources peak in this region. Given the increased longevity and artificial light sources emitting at biologically unfriendly wavelengths, attention has to be directed towards light in man's environment as a risk factor in age-related ocular diseases.

    2013-10-01

    As the population is ageing globally, both ageing and obesity are recognized as major public health challenges. The aim of this narrative review is to present and discuss the current evidence on the changes in body composition, energy balance and endocrine environment that occur in the ageing man. Obesity in the ageing man is related to changes in both body weight and composition due to alterations in energy intake and total energy expenditure. In addition, somatopenia (decreased GH secretion), late-onset hypogonadism (LOH), changes in thyroid and adrenal function, as well as changes in appetite-related peptides (leptin, ghrelin) and, most importantly, insulin action are related to obesity, abnormal energy balance, redistribution of the adipose tissue and sarcopenia (decreased muscle mass). A better understanding of the complex relationship of ageing-related endocrine changes and obesity could lead to more effective interventions for elderly men.

  2. Symbolism in prehistoric man.

    2000-12-01

    The aptitude for symbolization, characteristic of man, is revealed not only in artistic representations and funerary practices. It is exhibited by every manifestation of human activity or representation of natural phenomena that assumes or refers to a meaning. We can recognize functional symbolism (tool-making, habitative or food technology), social symbolism, (language and social communication) and spiritual symbolism (funerary practices and artistic expressions). On the basis of these concepts, research into symbolism in prehistoric man allows us to recognize forms of symbolism already in the manifestations of the most ancient humans, starting with Homo habilis (or rudolfensis). Toolmaking, social organization and organization of the territory are oriented toward survival and the life of the family group. They attest to symbolic behaviors and constitute symbolic systems by means of which man expresses himself, lives and transmits his symbolic world. The diverse forms of symbolism are discussed with reference to the different phases of prehistoric humanity.

    1994-10-01

    The 70-kg Standard Man or Reference Man has been used in physiological models since at least the 1920s to represent adult males. It came into use in radiation protection in the late 1940s and was developed extensively during the 1950s and used by the International Commission on Radiological Protection (ICRP) in its Publication 2 in 1959. The current Reference Man for Purposes of Radiation Protection is a monumental book published in 1975 by the ICRP as ICRP Publication 23. It has a wealth of information useful for radiation dosimetry, including anatomical and physiological data, gross and elemental composition of the body and organs and tissues of the body. The anatomical data includes specified reference values for an adult male and an adult female. Other reference values are primarily for the adult male. The anatomical data include much data on fetuses and children, although reference values are not established. There is an ICRP task group currently working on revising selected parts of the Reference Man document.

    Fibrodysplasia ossificans progressiva (FOP) is a rare hereditary connective tissue disease characterized by the progressive ectopic ossification of ligaments, tendons, and facial and skeletal muscles throughout life. Symptoms begin in childhood as localized soft tissue swellings. Immobility and articular dysfunction appear with involvement of the spine and proximal extremities. The temporomandibular joint (TMJ) is a critical component involved in the maxillofacial region, resulting in severe limitation of masticatory function, although TMJ involvement is rare. The aim of this article is to present a 28-year-old man with dental problems and slowly progressive limitation of motion in the jaw, knees, shoulders and hips as well as neck distortion.

  11. A Case of Mysterious Impacted Duodenal Foreign Body Presenting with Halitosis

    The majority of gastrointestinal (GI) foreign bodies (FBs) discovered in adults are the result of intentional ingestion, most of which are found in patients with a preexisting psychiatric illness, with substance abuse disorders, or in people seeking secondary gain. No similar case of internal injuries following unintentional ingestion of a barbecue grill cleaning brush bristle has been reported. A 58-year-old Caucasian male with no significant history presented with complaint of halitosis, not improving after oral care and dental hygiene measures. He denied any other symptoms. After ruling out oral causes of halitosis, an esophagogastroduodenoscopy was performed, which revealed a black wire-shaped metallic FB embedded in the duodenum. The FB was identified as a silver metallic flexible wire resembling the bristle of a barbecue grill cleaning brush. The halitosis resolved completely within 3 weeks of the removal of the FB. To the best of our knowledge, this is the first case of duodenal impaction of a barbecue grill cleaning brush bristle atypically presenting with halitosis. Physicians’ awareness of this potential injury from grill cleaning brush bristles would lead to a quick diagnosis after a focused history. Also avid grillers must be made aware of this potential hazard and should be encouraged to carefully examine the barbecue grill surface for any remnant bristle of the grill cleaning brush. Appropriate history taking, considering GI causes as potentially inducing halitosis, and an awareness of this entity among providers are important to facilitate prompt diagnoses and prevent major adverse outcomes.

  12. Specific killing of cytotoxic T cells and antigen-presenting cells by CD4+ cytotoxic T cell clones. A novel potentially immunoregulatory T-T cell interaction in man

    PubMed Central

    1990-01-01

    Mycobacterial antigens not only stimulate Th cells that produce macrophage-activating factors, but also CD4+ and CD8+ CTL that lyse human macrophages. The mycobacterial recombinant 65-kD hsp was previously found to be an important target antigen for polyclonal CD4+ CTL. Because of the major role of 65-kD hsp in the immune response to mycobacterial as well as autoantigens, we have studied CTL activity to this protein at the clonal level. HLA-DR or HLA-DQ restricted, CD4+CD8- T cell clones that recognize different peptides of the M. leprae 65-kD hsp strongly lysed EBV-BLCL pulsed with specific but not irrelevant peptide. No bystander lysis of B cells, T cells, or tumor cells was seen. Target cell lysis could not be triggered by PMA + Ca2+ ionophore alone and depended on active metabolism. Interestingly, these CD4+ CTL also strongly lysed themselves and other HLA-class II compatible CD4+ (TCR-alpha/beta or -gamma/delta) or CD8+ CTL clones in the presence of peptide, suggesting that CTL are not actively protected from CTL- mediated lysis. Cold target competition experiments suggested that EBV- BLCL targets were more efficiently recognized than CD4+ CTL targets. These results demonstrate that hsp65 peptide-specific HLA class II- restricted CD4+ T cell clones display strong peptide-dependent cytolytic activity towards both APCs, and, unexpectedly, CD4+ and CD8+ CTL clones, including themselves. Since, in contrast to murine T cells human T cells express class II, CTL-mediated T cell killing may represent a novel immunoregulatory pathway in man. PMID:1972178

    Typhoon Man-Yi was pummeling the Japanese island of Okinawa with winds between 230 and 295 kilometers per hour (125-160 knots, 144-184 miles per hour) and heavy rain on the morning of July 13, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured this image. The immense storm covered hundreds of kilometers with spiraling bands of thunderstorms, though it had lost the distinctive cloud-free eye it exhibited the day before. Typhoons are common in Japan, but powerful typhoons usually strike the island nation later in the year. The Japan Meteorological Agency said that Man-Yi is the fourth typhoon of the 2007 season and may be the most powerful ever observed in the northwest Pacific in July, reported Kyodo News. The Joint Typhoon Warning Center expected the typhoon to strike Kyushu, a southern Japanese island, on July 14, and then curve northeast along the eastern shore of Japan. By the time the storm reaches Tokyo on July 15, it should be degraded to a tropical storm. As of July 13, Typhoon Man-Yi had injured eight and flooded twenty houses in Okinawa, and forced airlines to cancel hundreds of flights, said Kyodo News. The storm was expected to bring heavy rain to Japan's Pacific coast. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response team.

    Manned orbiting stopover round trips to Venus are studied for departure dates between 1975 and 1986 over a range of trip times and stay times. The use of highly elliptic parking orbits at Venus leads to low initial weights in Earth orbit compared with circular orbits. For the elliptic parking orbit, the effect of constraints on the low altitude observation time on the initial weight is shown. The mission can be accomplished with the Apollo level of chemical propulsion, but advanced chemical or nuclear propulsion can give large weight reductions. The Venus orbiting mission weights than the corresponding Mars mission.

    The resiliency and adaptive ability of microbial life in real time on Earth relies heavily upon horizontal gene transfer. Based on that knowledge, how likely is earth based microbial life to colonize extraterrestrial targets such as Mars? To address this question, we consider manned and unmanned space exploration, the resident microbiota that is likely to inhabit those vehicles, the adaptive potential of that microbiota in an extraterrestrial setting especially with regards to mobile genetic elements, and the likelihood that Mars like environments could initiate and sustain colonization.

  16. The manned space station

    NASA Astrophysics Data System (ADS)

    Kovit, B.

    The development and establishment of a manned space station represents the next major U.S. space program after the Space Shuttle. If all goes according to plan, the space station could be in orbit around the earth by 1992. A 'power tower' station configuration has been selected as a 'reference' design. This configuration involves a central truss structure to which various elements are attached. An eight-foot-square truss forms the backbone of a structure about 400 feet long. At its lower end, nearest the earth, are attached pressurized manned modules. These modules include two laboratory modules and two so-called 'habitat/command' modules, which provide living and working space for the projected crew of six persons. Later, the station's pressurized space would be expanded to accommodate up to 18 persons. By comparison, the Soviets will provide habitable space for 12 aboard a 300-ton station which they are expected to place in orbit. According to current plans the six U.S. astronauts will work in two teams of three persons each. A ninety-day tour of duty is considered.

  18. A Case Report Describing a Rare Presentation of Simultaneous Occurrence of MPO-ANCA-Associated Vasculitis and Rheumatoid Arthritis

    PubMed Central

    Papireddy, Muralidhar; Gao, John

    2016-01-01

    Background. Renal-limited myeloperoxidase vasculitis with simultaneous rheumatoid arthritis is reported as a rare occurrence. Review of literature suggests that most patients had a diagnosis of rheumatoid arthritis for several years prior to presenting with renal failure from myeloperoxidase vasculitis. Case Presentation. A 58-year-old Caucasian male presented to the hospital experiencing malaise, fevers, decreased oral intake, nausea, and vomiting for one week duration. His past medical history consisted of newly diagnosed but untreated rheumatoid arthritis, hypertension, and non-insulin-dependent diabetes mellitus. He was found to have acute renal failure, proteinuria, and hypoglycemia. Standard therapy, including intravenous fluids, did not improve his acute renal failure. A vasculitis workup resulted in a positive myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA). Renal biopsy revealed crescentic glomerulonephritis (GN) pauci-immune type, suggestive of MPO-ANCA-associated vasculitis (MPO-AAV). Treatment consisted of prednisone, cyclophosphamide, and seven cycles of plasmapheresis, in addition to hemodialysis for uremia. Upon discharge, he received hemodialysis for another week and continued treatment with cyclophosphamide and prednisone. Conclusion. Patients with longstanding rheumatoid arthritis may develop renal failure due to nonsteroidal anti-inflammatory medication use and AA type amyloidosis; however, necrotizing glomerulonephritis with crescent formation has been rarely reported. This stresses the importance of early recognition and swift initiation of treatment. PMID:27891268

    1973-01-01

    The present work reports on a study of the technology required to advance the state of the art in man/machine communications. The study involved the development and demonstration of both hardware and software to effectively implement man/computer interactive channels of communication. While tactile and visual man/computer communications equipment are standard methods of interaction with machines, man's speech is a natural media for inquiry and control. As part of this study, a word recognition unit was developed capable of recognizing a minimum of one hundred different words or sentences in any one of the currently used conversational languages. The study has proven that efficiency in communication between man and computer can be achieved when the vocabulary to be used is structured in a manner compatible with the rigid communication requirements of the machine while at the same time responsive to the informational needs of the man.

  20. Design and finite element analysis of oval man way

    SciTech Connect

    Hari, Y.; Gryder, B.

    1996-12-01

    This paper presents the design of an oval man way in the side wall of a cylindrical pressure vessel. ASME Code Section 8 is used to obtain the design parameters of the oval man way, man way cover and bolts. The code calculations require some assumptions which may not be valid. A typical design example is taken. STAAD III finite element code with plate elements is used to model the oval man way, man way cover and bolts. The stresses calculated using ASME Code Section 8 and other analytical formulas for plate and shells are compared with the stresses obtained by Finite Element Modeling. This paper gives the designer of oval man way the ability to perform a finite element analysis and compare it with the analytical calculations and assumptions made. This gives added confidence to the designer as to the validity of his calculations and assumptions.

    1973-01-01

    A computerized anatomical man (CAM) model, representing the most detailed and anatomically correct geometrical model of the human body yet prepared, has been developed for use in analyzing radiation dose distribution in man. This model of a 50-percentile standing USAF man comprises some 1100 unique geometric surfaces and some 2450 solid regions. Internal body geometry such as organs, voids, bones, and bone marrow are explicitly modeled. A computer program called CAMERA has also been developed for performing analyses with the model. Such analyses include tracing rays through the CAM geometry, placing results on magnetic tape in various forms, collapsing areal density data from ray tracing information to areal density distributions, preparing cross section views, etc. Numerous computer drawn cross sections through the CAM model are presented.

    We present a case of transient cortical blindness secondary to contrast medium toxicity. A 58-year-old man had successful endovascular coiling of a right posterior inferior cerebellar artery aneurysm but became confused and unable to see after the procedure. His visual acuity was no light perception bilaterally. Clinically, there was no new intra-ocular pathology. An urgent non-contrast computed tomography scan of the brain showed cortical hyperdensity in both parieto-occipital cortices, consistent with contrast medium leakage through the blood-brain barrier from the coiling procedure. The man remained completely blind for 72 hours, after which his visual acuity improved gradually back to his baseline level.

    Human explorers had a fundamental role in the success of the APOLLO moon programme, they were at the same time the indispensable pilots, scientific operators and on the last missions lead scientists. Since, man did not either return to the moon or land on Mars but manned operation centres on the earth are now conducting extensive telescience on both celestial bodies. Manned flights to moon, Mars and asteroids are however still on the agenda and even if the main drive of these projects is outside science, it is to the planetary scientists to both prepare the data bases necessary for these flights and to ensure that the scientific advantage of conducting research in real time and in situ is exploited to the maximum. The current manned flight programme in Europe concentrates on the use of the International Space Station, the scientific activities can be roughly divided between the pressurized payloads and the external payloads. Technology developments occur also in parallel and prepare new exploration techniques. The current planning leads to exploitation up to 2020 but the space agencies study further extensions, the date of 2028 having already been considered. The relation of these programmes to future manned planetary exploration will be described both from the science and development point of view. The complementary role of astronauts and ground operation centres will be described on the basis of the current experience of operation centres managing the International Space Station. Finally, the NASA ORION project of exploration in the solar system will be described with emphasis on its current European participations. The science opportunities presented by independent ventures as Inspiration Mars or Mars One will be presented.

  14. Asphalt and risk of cancer in man.

    PubMed Central

    Chiazze, L; Watkins, D K; Amsel, J

    1991-01-01

    Epidemiological publications regarding the carcinogenic potential of asphalt (bitumen) are reviewed. In 1984 the International Agency for Research on Cancer (IARC) stated that there is "inadequate evidence that bitumens alone are carcinogenic to humans." They did, however, conclude that animal data provided sufficient evidence for the carcinogenicity of certain extracts of steam refined and air refined bitumens. In the absence of data on man, IARC considered it reasonable to regard chemicals with sufficient evidence of carcinogenicity in animals as if they presented a carcinogenic risk to man. Epidemiological data for man accumulated since the IARC report do not fulfil the criteria for showing a causal association between exposure to asphalt and development of cancer. The studies cited all suffer from a lack of data on exposure or potential confounders, which are necessary to establish whether or not such an association may or may not exist. In view of the evidence (or lack thereof) regarding asphalt today, an appropriate public health attitude suggests at least that action be taken to protect those working with asphalt by monitoring the workplace, taking whatever steps are possible to minimise exposures and to inform workers of potential hazards. At the same time, a need exists for well designed analytical epidemiological studies to determine whether a risk of cancer in man exists from exposure to asphalt. PMID:1878310

  16. Poor man`s parallelism in environmental management

    SciTech Connect

    Johnson, V.M.; Rogers, L.L.

    1995-02-01

    Poor man`s parallelism is a term to describe the harnessing of commonly available computational approaches containing a high degree of implicit or explicit parallelism with distributed computer resources to produce a large gain in processing time. The distinguishing features of poor man`s techniques are their accessibility and relatively low cost. In some circumstances, the clever exploitation of existing hardware and software may achieve as much improvement in the timely completion of tasks as do high-end, state-of-the-art parallel technologies. The ANN-GA approach to the optimization of environmental remediation strategies is an example of poor man`s parallelism: it integrates two well-known computational technologies, artificial neural networks (ANNs) and the genetic algorithm (GA), with a simple scheme for exploiting a network of Unix workstations to solve a nonlinear combinatorial optimization problem. Although this work has been motivated by the need to tame a computational tiger rather than to experiment with different flavors of parallelism, the approach has reached a level of maturity where it is instructive to examine how parallelism is embodied in its various components. It also stands as a demonstration of how even resource-lean organizations can take advantage of parallelism to solve problems.

  17. Estimation of dose to man from environmental tritium

    SciTech Connect

    Rohwer, P S; Etnier, E L

    1980-01-01

    Factors important for characterization of tritium in environmental pathways leading to exposure of man are reviewed and quantification of those factors is discussed. Parameters characterizing the behavior of tritium in man are also subjected to review. Factors to be discussed include organic binding, bioaccumulation, quality factor and transmutation. A variety of models are presently in use to estimate dose to man from environmental releases of tritium. Results from four representative models are compared and discussed. Site-specific information is always preferable when parameterizing models to estimate dose to man. There may be significant differences in dose potential among geographic regions due to variable factors. An example of one such factor examined is absolute humidity. It is concluded that adequate methodologies exist for estimation of dose to man from environmental tritium although a number of areas are identified where additional tritium research is desirable.

    Wierzbanowski, Theodore; Kasten, Terry D.

    1990-10-01

    The assessment of unmanned approaches to experimental aerospace vehicles in general and to the NASP program in particular is summarized. Technical requirements for NASP demonstration are presented and unmanned options for satisfying requirements are discussed. The X-30 sensitivities to technical requirements are described. A correlation of the NASP program to prior flight test programs, both manned and unmanned, is also presented. It is noted that subscale vehicles may reduce risk by as much as 18 percent for approximately $200 M. It is concluded that half-scale vehicles may reduce program risk by 60 percent, while reducing X-30 costs by 40 percent. Also, an unmanned X-30 will probably cost more than a manned X-30 due to costs associated with additional software development and ground support systems costs.

  2. Hermes - A manned European system

    NASA Astrophysics Data System (ADS)

    Cretenet, J.-C.

    Features of a European hypersonic winged reentry vehicle, Hermes, are presented, together with the technology requirements for its development and the missions it would serve. LEO is beginning to hold promise for the manufacture of materials in microgravity and/or vacuum conditions in orbiting facilities which need to be serviced. A manned, reusable, winged reentry vehicle would permit the delivery and return of payloads from space, recovery of the first stage of the Ariane V rocket for reuse, and return of the Hermes to a landing at the Kourou launch site. The avionics would be similar to those of modern aircraft, as would the landing system. In-orbit operational techniques would be needed, as would an internal environment similar to Spacelab, a rigid turnaround time, high utilization rate, and a 10 yr lifetime. The length of the Hermes is projected as 12.5 m, wingtip to wingtip breadth of 7.4 m, and a total mass of 11,400 kg for a heliosynchronous orbit mission, while 15,400 kg are available for a circular, 490 m/sec orbit.

    For realizing the flexible man-machine collaboration, understanding of facial expressions and gestures is not negligible. In our method, we proposed a hierarchical recognition approach, for the understanding of human emotions. According to this method, the facial AFs (action features) were firstly extracted and recognized by using histograms of optical flow. Then, based on the facial AFs, facial expressions were classified into two calsses, one of which presents the positive emotions, and the other of which does the negative ones. Accordingly, the facial expressions belonged to the positive class, or the ones belonged to the negative class, were classified into more complex emotions, which were revealed by the corresponding facial expressions. Finally, the system architecture how to coordinate in recognizing facil action features and facial expressions for man-machine collaboration was proposed.

  6. Manning's roughness coefficient for Illinois streams

    Soong, David T.; Prater, Crystal D.; Halfar, Teresa M.; Wobig, Loren A.

    2012-01-01

    Manning's roughness coefficients for 43 natural and constructed streams in Illinois are reported and displayed on a U.S. Geological Survey Web site. At a majority of the sites, discharge and stage were measured, and corresponding Manning's coefficients—the n-values—were determined at more than one river discharge. The n-values discussed in this report are computed from data representing the stream reach studied and, therefore, are reachwise values. Presentation of the resulting n-values takes a visual-comparison approach similar to the previously published Barnes report (1967), in which photographs of channel conditions, description of the site, and the resulting n-values are organized for each site. The Web site where the data can be accessed and are displayed is at URL http://il.water.usgs.gov/proj/nvalues/.

    1989-01-01

    A method to achieve man-in-the-control-loop simulation is presented. Emerging real-time dynamics simulation suggests a potential for creating an interactive design workstation with a human operator in the control loop. The recursive formulation for multibody dynamics simulation is studied to determine requirements for man-in-the-control-loop simulation. High speed computer graphics techniques provides realistic visual cues for the simulator. Backhoe and robot arm simulations are implemented to demonstrate the capability of man-in-the-control-loop simulation.

  8. GD goal - Lower-cost manned lunar missions

    Lenorovitz, Jeffrey M.

    1993-01-01

    A proprietary feasibility evaluation is presented for more cost-effective means of accomplishing manned lunar missions than those of the Apollo program. The proposal involves a series of flights employing the Space Shuttle Orbiter and an expendable launcher such as the Ariane 5, which would be supplied by the ESA. The crew module would be externally similar to the Apollo three-man capsule, but would be smaller due to a two-man crew. Cost projections are made which encompass hardware development, production, testing, and operations (including those of the Space Shuttle and Ariane 5).

  9. Mannans and endo-β-mannanases (MAN) in Brachypodium distachyon: expression profiling and possible role of the BdMAN genes during coleorhiza-limited seed germination

    PubMed Central

    González-Calle, Virginia; Barrero-Sicilia, Cristina; Carbonero, Pilar; Iglesias-Fernández, Raquel

    2015-01-01

    Immunolocalization of mannans in the seeds of Brachypodium distachyon reveals the presence of these polysaccharides in the root embryo and in the coleorhiza in the early stages of germination (12h), decreasing thereafter to the point of being hardly detected at 27h. Concurrently, the activity of endo-β-mannanases (MANs; EC 3.2.1.78) that catalyse the hydrolysis of β-1,4 bonds in mannan polymers, increases as germination progresses. The MAN gene family is represented by six members in the Brachypodium genome, and their expression has been explored in different organs and especially in germinating seeds. Transcripts of BdMAN2, BdMAN4 and BdMAN6 accumulate in embryos, with a maximum at 24–30h, and are detected in the coleorhiza and in the root by in situ hybridization analyses, before root protrusion (germination sensu stricto). BdMAN4 is not only present in the embryo root and coleorhiza, but is abundant in the de-embryonated (endosperm) imbibed seeds, while BdMAN2 and BdMAN6 are faintly expressed in endosperm during post-germination (36–42h). BdMAN4 and BdMAN6 transcripts are detected in the aleurone layer. These data indicate that BdMAN2, BdMAN4 and BdMAN6 are important for germination sensu stricto and that BdMAN4 and BdMAN6 may also influence reserve mobilization. Whether the coleorhiza in monocots and the micropylar endosperm in eudicots have similar functions, is discussed. PMID:25922488

    A view of the facility and operational requirements involved in performing a manned thermal vacuum test is presented. The requirements fall into two major categories. The first category deals with placing the suited crewmen in a hazardous environment and assuring their safety. The second category deals with the constraints and special requirements involved with a suited crewman operating flight hardware in a 1-G environment. Design areas that deal with man rating a chamber, including fire suppression, emergency repress, emergency power, backups, reliable instrumentation and data systems, communications, television monitoring, biomedical monitoring, material compatibilities, and equipment supporting the Extravehicular Mobility Unit (EMU) are discussed. The operational issues that are peculiar to manned testing such as test rules, test procedures, test protocol, emergency drills, availability of hyperbaric facilities, test team training and certification engineering concerns for a safe mechanical and instrumentation buildup, hazard analysis, and Failure Modes and Effects Analysis are discussed. The constraints and special requirements involved with a suited crewman operating flight hardware in a 1-G environment are addressed.

    A 58-year-old man re-presented with symptoms of angina 3 months after percutaneous transluminal coronary angioplasty (PTCA) and stenting to his proximal left anterior descending artery (LAD). Angiography revealed ostial in-stent restenosis of the LAD, which was treated with rotational atherectomy and a cutting balloon PTCA. Combining two useful technologies for treating in-stent restenosis may prove to yield better results than using either technique alone. Long-term benefit will need to be assessed by randomized studies.

    Myofibroma is a rare benign neoplasm of myofibroblastic origin. It typically occurs in the skin and subcutaneous tissues of the head and neck in infants and young children as multicentric lesions known as infantile myofibromatosis. Intraosseous myofibromas are very rare and are typically destructive lesions that predominantly affect craniofacial bones in the setting of myofibromatosis. Solitary, intraosseous myofibromas in adults are exceedingly rare. Herein, we report a myofibroma involving the middle phalanx of the right index finger in a 58-year-old man who presented with a pathologic fracture. Twelve other cases of adult-onset, intraosseous myofibroma were compiled from the English language literature and integrated with this report.

    We report the case of a 58-year-old man presented with bleeding ulcer of the left arm caused by a high-flow type-C arteriovenous malformation (AVM), feed by branches from both the subclavian arteries. He had been previously treated with AVM sclerotherapy, embolization, humeral artery endografting, and open surgery. We urgently performed coil embolization of the left vertebral artery, and we covered the huge subclavian artery by a thoracic endograft. Then, we embolized the right tyrocervical trunk. The result was an immediate interruption of bleeding. At 12 months, the patient had no neurologic complications, and the upper limb continued to decompress.

    A 58-year-old man with a history of severe invalidating claudicatio intermittens underwent femoropopliteal bypass with a human umbilical vein graft. Seven years later he presented with a painful enlarging mass in the middle portion of his right thigh. The duplex scan showed a pseudoaneurysm of the body of the prosthesis, which was confirmed by angiography. As an alternative to surgical management, Wallgraft endoprosthesis was used for endoluminal exclusion of the pseudoaneurysm. To our knowledge, this technique has never been used before in such a case.

Although the diagnosis of pulmonary embolism had been considered, chest radiograph and pulmonary perfusion scintigraphy showed a mass in the right hilum and no perfusion in the right lung. (18)F-fluorodeoxyglucose positron emission computed tomography (FDGPET) showed increased FDG uptake in the mass obstructing the right pulmonary artery. Fine-needle biopsy revealed a pathological diagnosis of pulmonary artery intimal sarcoma. The patient was successfully treated with radiotherapy and adjuvant chemotherapy. FDG-PET was used for monitoring the response to therapy.

    1961-01-01

    The author reviews the published findings on the carriage of Staphylococcus pyogenes var. aureus during the last two decades, dealing mainly with observations made in British Commonwealth countries, Scandinavia and the USA. The importance of the role played by staphylococcal carriers in the spread of infection both in hospitals and among adults and children in the general population is clearly brought out and is of particular interest in view of the current increase in resistance of staphylococcal strains to antibiotics. There does not appear to have been any well-defined trend towards either an increase or a decrease in staphylococcal carriage in the past twenty years; annual variations have been quite considerable and the precipitate drop in the carriage rate in hospitals in 1949 (perhaps due to the extensive use of penicillin) has since been made up. A particularly high carriage rate was found among hospital staff and twice as high a rate among children born in hospitals as among those delivered at home. Closer study and better control of staphylococcal infections in hospital wards are clearly necessary. It is appreciated, however, that, before more effective control measures can be taken, there must be improvements in the present methods of sampling, in the testing of strains for pathogenicity and in other techniques.

    The primary change in crew capsule definition is a smaller MOTV crew capsule, switching from a 3-man capsule to a 2-man capsule. A second change permitted crew accommodations for sleeping and privacy to be combined with the flight station. The current baseline DRM, ER1, requires 2 men for 3 to 4 days to repair a multi-disciplined GOE Platform and a modest amount of mission dedicated hardware. A 2-man MOTV crew capsule to be used as a design reference point for the OTV, and its interfaces between the STS and other associated equipment or facilities are described in detail. The functional capabilities of the 2-man capsule, as well as its application to a wide range of generic missions, is also presented. The MOTV turnaround is addressed and significant requirements for both space based and ground based scenarios are summarized.

    The literature dealing with the protection of man against rabies over the past 70 years in many parts of the world is reviewed, and the salient problems of our present state of knowledge analysed. The author discusses the measures currently in use for eliminating canine rabies by quarantine, regulation of the dog population, and—in particular—mass vaccination of dogs, with a detailed survey of the questions of immunological research which this method raises. Measures for suppressing the disease in other vectors are also described. It is concluded that, given effective education of the public and the widespread use of canine mass vaccination, human rabies is a preventable disease. PMID:13182607

  1. RenderMan design principles

    NASA Technical Reports Server (NTRS)

    Apodaca, Tony; Porter, Tom

    1989-01-01

    The two worlds of interactive graphics and realistic graphics have remained separate. Fast graphics hardware runs simple algorithms and generates simple looking images. Photorealistic image synthesis software runs slowly on large expensive computers. The time has come for these two branches of computer graphics to merge. The speed and expense of graphics hardware is no longer the barrier to the wide acceptance of photorealism. There is every reason to believe that high quality image synthesis will become a standard capability of every graphics machine, from superworkstation to personal computer. The significant barrier has been the lack of a common language, an agreed-upon set of terms and conditions, for 3-D modeling systems to talk to 3-D rendering systems for computing an accurate rendition of that scene. Pixar has introduced RenderMan to serve as that common language. RenderMan, specifically the extensibility it offers in shading calculations, is discussed.

    The quantity of online documentation and viewing tools is overwhelming, with the World Wide Web, vendor-supported and local-site documentation and tools, etc. Maintaining the information and tools is equally overwhelming. However, statistics show that MAN usage far exceeds usage of other online documentation tools. But as one knows, MAN has its own problems, and at the forefront are MAN`S many inconsistencies. MAN is the standard Unix (and POSIX) tool which provides good summary information for those already familiar with a command. Well-written manual pages provide a good overall documentation. However, when a particular manual becomes too long, it becomes a cumbersome method to use for reading documentation. The paper describes MAN`s problems and the National Energy Research Supercomputer Center requirements for MAN.

    The multiple man machine interfaces inherent in military pilot training, their social implications, and the issue of possible negative feedback were explored. Modern technology has produced machines which can see, hear, and touch with greater accuracy and precision than human beings. Consequently, the military pilot is more a systems manager, often doing battle against a target he never sees. It is concluded that unquantifiable human activity requires motivation that is not intrinsic in a machine.

    Nine reports published in this volume study the uneasy coexistence of modern man and the complex society he has wrought. Man's apparent disorganized behavior is attributed to his inability to adapt readily to the charged pace of technological change. To combat the advancement of machine over man, he must, therefore, insist that moral and…

  10. [Anaesthetic management of Stiff Man syndrome].

    PubMed

    Marín, T; Hernando, D; Kinast, N; Churruca, I; Sabate, S

    2015-04-01

    Stiff Man syndrome or stiff-person syndrome is a rare autoimmune disorder. It is characterized by increased axial muscular tone and limb musculature, and painful spasms triggered by stimulus. The case is presented of a 44-year-old man with stiff-person syndrome undergoing an injection of botulinum toxin in the urethral sphincter under sedation. Before induction, all the surgical team were ready in order to minimise the anaesthetic time. The patient was monitored by continuous ECG, SpO2 and non-invasive blood pressure. He was induced with fractional dose of propofol 150 mg, fentanyl 50 μg and midazolam 1mg. Despite careful titration, the patient had an O2 saturation level of 90%,which was resolved by manual ventilation. There was no muscle rigidity or spasm during the operation. Post-operative recovery was uneventful and the patient was discharged 2 days later. A review of other cases is presented. The anaesthetic concern in patients with stiff-person syndrome is the interaction between the anaesthetic agents, the preoperative medication, and the GABA system. For a safe anaesthetic management, total intravenous anaesthesia is recommended instead of inhalation anaesthetics, as well as the close monitoring of the respiratory function and the application of the electrical nerve stimulator when neuromuscular blockers are used.

    A natural seismicity of Kuznetsk Basin is confined in the main to mountain frame of Kuznetsk hollow. In this paper materials of experimental work with local station networks within sediment basin are presented. Two types of seismicity display within Kuznetsk hollow have been understood: first, man-caused seismic processes, confined to mine working and concentrated on depths up to one and a half of km; secondly, seismic activations on depths of 2-56 km, not coordinated in plan with coal mines. Every of studied seismic activations consists of large quantity of earthquakes of small powers (Ms=1-3). From one to first tens of earthquakes were recorded in a day. The earthquakes near mine working shift in space along with mine working, and seismic process become stronger at the instant a coal-plough machine is operated, and slacken at the instant the preventive works are executed. The seismic processes near three lavas in Kuznetsk Basin have been studied in detail. Uplift is the most typical focal mechanism. Activated zone near mine working reach in diameter 1-1,5 km. Seismic activations not linked with mine working testify that the subsoil of Kuznetsk hollow remain in stress state in whole. The most probable causes of man-caused action on hollow are processes, coupled with change of physical state of rocks at loss of methane from large volume or change by mine working of rock watering in large volume. In this case condensed rocks, lost gas and water, can press out upwards, realizing the reverse fault mechanism of earthquakes. A combination of stress state of hollow with man-caused action at deep mining account for activations nascent in Kuznetsk Basin. Today earthquakes happen mainly under mine workings, and damages of workings themselves do not register, but intensive shaking felt on surface calls for intent study of so dangerous phenomena.

    Human capabilities and requirements on space missions are discussed. Utilitarian and humanistic motivations for manned missions are considered, and a general program of development from easy space access and return, to a permanent LEO presence, to the limited self-sufficiency of man in space, is proposed. Man's potential as scientific observer, operator, and engineer/technician is illustrated with examples from the Apollo and Skylab missions. It is shown that future increases in man's space presence will require significant improvements in habitation technology, crew comfort and safety, operational effectiveness and reliability, and man/machine interactions: man-tended systems must be standardized and adapted to (mainly EVA) human servicing; permanently manned systems must be designed to attain levels of comfort, privacy, and overall habitability more like those expected on the ground.

    The program for the Apollo 16 flight was designed to include both safeguards against and investigations of the physiological problems arising from increase in the period of manned space flight. Precautions included the provision of a controlled diet with high potassium content, carefully controlled work loads and work-rest cycles, and an emergency cardiology consultation service, and investigations were made to enable preflight vs postflight comparisons of metabolic, cardiovascular, and central nervous system data. Results of these investigations indicate that adjustment to weightlessness can be satisfactorily assisted by appropriate countermeasures, including attention to diet.

    An overview of the conceptual study of spacecraft used for validating technologies which will be necessary for manned space development conducted by Japan in the future is presented. An Environmental Control and Life Support System (ECLSS) and two-phase liquid loop radiator experiment equipment were selected as the major and optional equipment to be installed onboard the manned engineering test satellites, respectively. Mission items for ECLSS experiment equipment were extracted and traded off from the following on-ground technologies: (1) technology for removing toxic substances, offensive substances, and fine particles from the atmosphere; (2) N2 and O2 partial pressure control and CO2 removal technologies; (3) gas sensing technology; and (4) temperature and humidity control technology. Comparison was conducted on three base-line configurations such as follows: (1) pressurized module (expendable) plus bus section (expendable); (2) pressurized module (retrievable) plus bus section (expendable); and (3) pressurized module (expendable) plus bus section (expendable) plus recovery section. The results of the review on the satellite system base on configuration of the above case (1) are outlined.

  18. Proposal for a remotely manned space station

    Minsky, Marvin

    1990-01-01

    The United States is in trouble in space. The costs of the proposed Space Station Freedom have grown beyond reach, and the present design is obsolete. The trouble has come from imagining that there are only two alternatives: manned vs. unmanned. Both choices have led us into designs that do not appear to be practical. On one side, the United States simply does not possess the robotic technology needed to operate or assemble a sophisticated unmanned space station. On the other side, the manned designs that are now under way seem far too costly and dangerous, with all of its thousands of extravehicular activity (EVA) hours. More would be accomplished at far less cost by proceeding in a different way. The design of a space station made of modular, Erector Set-like parts is proposed which is to be assembled using earth-based remotely-controlled binary-tree telerobots. Earth-based workers could be trained to build the station in space using simulators. A small preassembled spacecraft would be launched with a few telerobots, and then, telerobots could be ferried into orbit along with stocks of additional parts. Trained terrestrial workers would remotely assemble a larger station, and materials for additional power and life support systems could be launched. Finally, human scientists and explorers could be sent to the space station. Other aspects of such a space station program are discussed.

    1986-01-01

    A set of roving vehicle design requirements were postulated, corresponding to an idealized Mars transport vehicle operational scenario which could serve as a reference for a manned Mars mission. The ability of conventional vehicles to satisfy these requirements were examined. The study indicated that no conventional vehicle could satisfy all of the requirements, as the vehicles are presently configured. Consequently, the requirements have to either be relaxed and/or an alternative, less conventional vehicle design will have to be developed. A possible unconventional vehicle design which has received considerable attention for DARPA and the Army is the walker vehicle. The design issues associated with this vehicle are presented, along with a comparison of the performance capabilities of this technology vs. conventional vehicle technology.

  1. The rights of man and animal experimentation.

    PubMed

    Martin, J

    1990-09-01

    Since emotions give contradictory signals about animal experimentation in medical science, man's relationship to animals must be based upon reason. Thomas Aquinas argues that man is essentially different from animals because man's intellectual processes show evidence of an abstract mechanism not possessed by animals. Man's rights arise in association with this essential difference. The consequence is that only man possesses true rights by Aquinas's definition; animals have them only by analogy. However, cruelty to animals is illicit and they should be protected, principally not because they have rights, but because he who is cruel to animals is more likely to be cruel to his fellowman. If there is a need for animal experimentation in science for the good of man, this approach gives philosophical justification for experimentation, since man's well-being must come before that of animals because of his unique possession of rights. However, those experiments should be carried out in the kindest way possible, to promote kindness towards man. To see man as solely part of a biological continuum in competition for rights with those beings close to him biologically, detracts from man's dignity.

    The requirements for extended-duration space missions in earth orbit beyond those anticipated for the 7- to 30-day Shuttle Spacelab system have been examined. It has been determined that a continuously manned, free-flying orbital facility provides a realistic and cost-effective space platform for multidiscipline payloads designed to support research, applications, and system implementation programs such as the assembly of large space structures, and on-orbit space manufacturing. A conceptual description of such a manned facility (early Space Station) and the accommodations that it can provide using agencies and organizations is presented in this paper.

    This compilation of papers constitutes an interim report on the results of experiments conducted during the Gemini V manned space flight. The results of experiments conducted on Gemini III and IV manned space flights have been published previously in a similar interim report, "Manned Space Flight Experiments Symposium, Gemini Missions III and IV," which is available upon request from MSC Experiments Program Office, Houston, Texas (Code EX, Attention of R. Kinard). The Gemini V mission provided the greatest opportunity to date for conducting experiments; the increased mission duration of eight days provided this added capability. The total mission experiment complement was seventeen. Five experiments were designed to obtain basic scientific knowledge, five were medical, and seven were technological and engineering in nature. Six of the experiments had flown previously on Gemini IV, and eleven were new. The results of the experiments, including real-time modification to preflight plans made necessary by abnormal spacecraft system operation, are presented.

    The contemporary presence of organomegaly, skin manifestations, polyneuropathy, endocrinopathy and monoclonal component characterises the POEMS syndrome, often associated with osteosclerotic myeloma and Castelman's disease and more frequent in the Japanese. Clinical manifestations seem to be related to the production of many interleukins, mainly IL-1, IL-6 and TNF. Several endocrinopathies have been described, the most frequent being diabetes. Only one previous case of hypoparathyroidism associated with the syndrome has been described in medical reviews. Polyneuropathy is often sensitivo-motory and skin disease accounts for Raynaud phenomenon, skin pigmentation, hypertricosis and others. We describe the case of a 74-year-old man who underwent clinical examination for weakness mainly in the legs. Clinical and instrumental data showed rhabdomyolysis due to hypoparathyroidism. The contemporary presence of a monoclonal band of light chains on proteic electrophoresis, organomegaly and distal leg neuropathy allowed us to make a diagnosis of POEMS syndrome.

    2017-01-01

    Background Medical treatment of cranio-cervical pain can be suboptimal in patients with internal carotid artery (ICA) dissection. We report the use of cervical sympathetic block for treatment of pain in two patients with ICA dissection. Case Reports A 58-year-old man and a 43-year-old woman presented with severe cranio-cervical pain associated with left and right ICA dissection confirmed by magnetic resonance imaging and cerebral angiography. Due to suboptimal control of pain with medical treatment, cervical sympathetic block was performed under fluoroscopic guidance using 20 ml of bupivacaine injected lateral to the posterior aspect of sixth vertebral body in both patients. On self-reported pain scale, the 58-year-old man reported improvement in pain intensity from 8/10 pain to 0/10 within 1 h of blockade. The patient remained relatively pain free for the 24-h post blockade. Mild recurrence of pain was noted on Day 2. The 43-year-old woman reported improvement in pain intensity from 6/10 pain to 0/10 within 1 h of blockade. The patient remained pain free for five days with recurrence to previous intensity. Conclusion Cervical sympathetic blockade in patients with ICA dissection may be an effective option in the event of suboptimal pain control with medical treatment; however, the technique may be limited due to relatively short duration of action.

    We describe a 26-year-old man with metastatic choriocarcinoma who presented with hyperthyroidism associated with elevated β-human chorionic gonadotropin (B-HCG) and respiratory failure secondary to diffuse lung metastasis. After the first cycle of chemotherapy, the concentration of B-HCG dramatically decreased and the patient became euthyroid, allowing us to discontinue antithyroid medications. The patient's hyperthyroidism was caused by stimulation of the thyroid gland by high B-HCG levels, as shown by the marked improvement of the patient's thyroid function panel after chemotherapy.

    He was sitting on a large slab of rock. As he looked at the cloud of dust hanging hazily on the horizon, the piece of antler and the block of flint he held in his hand hung as if they were suspended from their previous rapid motion. The man gazed intently across the swaying grass which rose in wave-like billows across the distant hills. What was that dust - a herd of buffalo, a band of hunters, or were coyotes chasing the antelope again? After watching for a while he started again to chip the flint with a rapid twisting motion of the bone in his right hand. The little chips of flint fell in the grass before him. It is the same hill but the scene has changed. Seated on the same rock, holding the reins of a saddle horse, a man dressed in buckskin took the fur cap off his head and wiped his brow. He was looking intently across a brown and desolate landscape at a cloud of dust on the far horizon. Was it the hostile tribe of Indians? It could be buffalo. Nervously he kicked at the ground with the deerhide moccasin, pushing the flint chips out of the way. He wiped the dust from his long rifle. What a terrible place - no water, practically no grass, everything bare and brown. Now at sunset, slanting across the hills green with springtime, a cowman sits on a big rock, pushes his sombrero back on his head, and looks across the valley at a large but quiet herd of stock, moving slowly as each steer walks from one lush patch of grass to another, nibbling. Suddenly he stood up. Far on the horizon some dark objects were moving. Is it the sheepmen? Could it be the stage coach from Baggs to the Sweetwater Crossing?Same hill - a gray truck was grinding slowly toward the summit. It pulled up near a small fenced enclosure where there were some instruments painted a bright silver color. A man stepped out of the truck and turned to his younger companion, "You've never found an arrowhead? Maybe you have never thought about it correctly. If you want to find where an Indian camped long

    The universe has always aroused people's curiosity. It fascinates and at the same time scares in its vastness. Encourages us to reflect of the meaning of human life. This begs the questions: whether there is a life beyond Earth? Whether is it possible that the man is alone in such a large space? These questions still remain unanswered, and topics concerning "the cosmos" constantly evoke many emotions. It is especially fascinating for the youngest students. Quite often, preschoolers can flawlessly name the planets according to their order of appearance in relation to the sun. They are happy to take the fun inspired by journeys into space. Teaching through action is extremely important for the development of the child-man* (Piaget, 2006). The thinking originates primarily from the action. Therefore, students should undertake independent research activities, perform experiments and conduct observations and thus raise questions about the world, looking for meanings and solutions. Adults (a teacher, a person with a passion) are to be the support in the search for knowledge, its processing and cleaning. Its role is to ensure a proper development of environment that is conducive to research activity. The answer to these requirements was to create in the oldest technical school in Poland (Railway Technical College, now Technical College No. 7) the astronomical observatory, which can be used by pupils of Warsaw's kindergartens and schools. There are organized activities for children and youth in this school, as well as trainings for teachers. Younger students during such an interdisciplinary courses are, among others, the opportunity to get acquainted with the construction of the telescope, they can build their own rockets and organize their racing or create your own star constellations. Older students as a result of observations and experiments may confirm or refute the hypothesis that the universe is within each of us. The classes are enriched using applications on

  1. Biomedical support of man in space

    NASA Astrophysics Data System (ADS)

    Pendergast, D. R.; Olszowka, A. J.; Rokitka, M. A.; Farhi, L. E.

    In its broadest sense, biomedical support of man in space must not be limited to assisting spacecraft crew during the mission; such support should also ensure that flight personnel be able to perform properly during landing and after leaving the craft. Man has developed mechanisms that allow him to cope with specific stresses in his normal habitat; there is indisputable evidence that, in some cases, the space environment, by relieving these stresses, has also allowed the adaptive mechanisms to lapse, causing serious problems after re-entry. Inflight biomedical support must therefore include means to simulate some of the normal stresses of the Earth environment. In the area of cardiovascular performance, we have come to rely heavily on complex feedback mechanisms to cope with two stresses, often combined: postural changes, which alter the body axis along which gravitational acceleration acts, and physical exercise, which increases the total load on the system. Unless the appropriate responses are reinforced continuously during flight, crew members may be incapacitated upon return. The first step in the support process must be a study of the way in which changes in g, even of short duration, affect these responses. In particular we should learn more about effects of g on the "on" and "off" dynamics, using a variety of approaches: increased acceleration on one hand at recumbency, immersion, lower body positive pressure, and other means of simulating some of the effects of low g, on the other. Once we understand this, we will have to determine the minimal exposure dose required to maintain the response mechanisms. Finally, we shall have to design stresses that simulate Earth environment and can be imposed in the space vehicle. Some of the information is already at hand; we know that several aspects of the response to exercise are affected by posture.

    Two frameworks for the study of man are discussed. The Cartesian model views man as a physical object. A dialectic framework, with the emphasis on the self, grew out of nineteenth century romanticism and reflects the theories of Hegel. Both models have had an effect on social psychology and the study of interpersonal communication. (BH)

    NASA Technical Reports Server (NTRS)

    Zimmerman, W. F.; Bard, J.; Feinberg, A.

    1985-01-01

    The man machine automation tradeoff methodology presented is of four research tasks comprising the autonomous spacecraft system technology (ASST) project. ASST was established to identify and study system level design problems for autonomous spacecraft. Using the Space Station as an example spacecraft system requiring a certain level of autonomous control, a system level, man machine automation tradeoff methodology is presented that: (1) optimizes man machine mixes for different ground and on orbit crew functions subject to cost, safety, weight, power, and reliability constraints, and (2) plots the best incorporation plan for new, emerging technologies by weighing cost, relative availability, reliability, safety, importance to out year missions, and ease of retrofit. A fairly straightforward approach is taken by the methodology to valuing human productivity, it is still sensitive to the important subtleties associated with designing a well integrated, man machine system. These subtleties include considerations such as crew preference to retain certain spacecraft control functions; or valuing human integration/decision capabilities over equivalent hardware/software where appropriate.

    NASA Technical Reports Server (NTRS)

    Parker, L. E.; Pin, F. G.

    1987-01-01

    This report presents a methodological approach to the dynamic allocation of tasks in a man-machine symbiotic system in the context of dexterous manipulation and teleoperation. This report addresses a symbiotic system containing two symbiotic partners which work toward controlling a single manipulator arm for the execution of a series of sequential manipulation tasks. It is proposed that an automated task allocator use knowledge about the constraints/criteria of the problem, the available resources, the tasks to be performed, and the environment to dynamically allocate task recommendations for the man and the machine. The presentation of the methodology includes discussions concerning the interaction of the knowledge areas, the flow of control, the necessary communication links, and the replanning of the task allocation. Examples of task allocation are presented to illustrate the results of this methodolgy.

  19. Space nuclear reactor shields for manned and unmanned applications

    NASA Technical Reports Server (NTRS)

    Mckissock, Barbara I.; Bloomfield, Harvey S.

    1990-01-01

    Missions which use nuclear reactor power systems require radiation shielding of payload and/or crew areas to predetermined dose rates. Since shielding can become a significant fraction of the total mass of the system, it is of interest to show the effect of various parameters on shield thickness and mass for manned and unmanned applications. Algorithms were developed to give the thicknesses needed if reactor thermal power, separation distances, and dose rates are given as input. The thickness algorithms were combined with models for four different shield geometries to allow tradeoff studies of shield volume and mass for a variety of manned and unmanned missions. Shield design tradeoffs presented in this study include the effects of: higher allowable dose rates; radiation hardened electronics; shorter crew exposure times; shield geometry; distance of the payload and/or crew from the reactor; and changes in the size of the shielded area. Specific NASA missions that were considered in this study include unmanned outer planetary exploration, manned advanced/evolutionary Space Station, and advanced manned lunar base.

    This report consolidates research carried out at Clemson University and Stanford University where a series of measurements were undertaken to identify the man-made radiation present in four bands used by rather different services, namely, L1 Band (1563.42 1587.42 MHz), the Unified S-Band (2025 2110 MHz), the 2.4 GHz Industrial, Scientific and Medical (ISM) Band (2400 2482.50 MHz), and the 23.6-24.0 GHz Passive Sensing Band. Results show that there were distinctive differences in the measurement data in the frequency bands, which should be expected based on the function/regulation associated with each. The GPS L1 Band had little to none terrestrial man-made sources, but the ISM 2.4 GHz Band had a large number of man-made sources regardless of the site and the time. The Unified S Band showed mixed results depending on the sites. The Passive Sensing Band does not contain appreciable man-made radiation.

    Kennewick Man, referred to as the Ancient One by Native Americans, is a male human skeleton discovered in Washington state (USA) in 1996 and initially radiocarbon-dated to 8340–9200 calibrated years BP1. His population affinities have been the subject of scientific debate and legal controversy. Based on initial study of cranial morphology it was asserted that Kennewick Man was neither Native American nor closely related to the Claimant Plateau tribes of the Pacific Northwest, who claimed ancestral relationship and requested repatriation under the Native American Graves Protection and Repatriation Act (NAGPRA). The morphological analysis was important to judicial decisions that Kennewick Man was not Native American and that therefore NAGPRA did not apply. Instead of repatriation, additional studies of the remains were permitted2. Subsequent craniometric analysis affirmed Kennewick Man to be more closely related to circumpacific groups such as the Ainu and Polynesians than he is to modern Native Americans2. In order to resolve Kennewick Man’s ancestry and affiliations, we have sequenced his genome to ~1× coverage and compared it to worldwide genomic data including the Ainu and Polynesians. We find that Kennewick Man is closer to modern Native Americans than to any other population worldwide. Among the Native American groups for whom genome wide data is available for comparison, several appear to be descended from a population closely related to that of Kennewick Man, including the Confederated Tribes of the Colville Reservation (Colville), one of the five tribes claiming Kennewick Man. We revisit the cranial analyses and find that, as opposed to genomic-wide comparisons, it is not possible on that basis to affiliate Kennewick Man to specific contemporary groups. We therefore conclude based on genetic comparisons that Kennewick Man shows continuity with Native North Americans over at least the last eight millennia. PMID:26087396

    QX MAN is a grid and solution file manipulation program written primarily for the PARC code and the GRIDGEN family of grid generation codes. QX MAN combines many of the features frequently encountered in grid generation, grid refinement, the setting-up of initial conditions, and post processing. QX MAN allows the user to manipulate single block and multi-block grids (and their accompanying solution files) by splitting, concatenating, rotating, translating, re-scaling, and stripping or adding points. In addition, QX MAN can be used to generate an initial solution file for the PARC code. The code was written to provide several formats for input and output in order for it to be useful in a broad spectrum of applications.

    PubMed Central

    Dissanaike, A. S.

    1979-01-01

    This article gives an account of the filarial parasites found in man and their potential transmissibility to and from other vertebrate animals under natural and experimental conditions. Those species that are regarded as being primarily parasites of other vertebrates, but which also infect man, are then dealt with in greater detail. These include the subperiodic strain of Brugia malayi and perhaps also B. pahangi, both of which are found in wild and domestic carnivores and monkeys, and Dirofilaria species of dogs and racoons. The Brugia parasites develop to maturity with the production of microfilaraemia and clinical manifestations in man similar to those caused by periodic B. malayi in man. Human dirofilariasis, on the other hand, represents a transmission cul-de-sac for the parasite. Clinical manifestations are mild or absent and generally the worms do not mature and, even if they do, they rarely give rise to microfilaraemia. D. immitis causes pulmonary dirofilariasis, and D. repens and D. tenuis give rise to subcutaneous nodules in man. The diagnosis of dirofilariasis depends on an awareness of the infection in the animal reservoirs and of the possibility of man being exposed to bites of infected vectors.

  19. Landing Energy Dissipation for Manned Reentry Vehicles

    NASA Technical Reports Server (NTRS)

    Fisher, Lloyd J., Jr.

    1960-01-01

    Analytical and experimental investigations have been made to determine the landing-energy-dissipation characteristics for several types of landing gear for manned reentry vehicles. The landing vehicles are considered in two categories: those having essentially vertical-descent paths, the parachute-supported vehicles, and those having essentially horizontal paths, the lifting vehicles. The energy-dissipation devices discussed are crushable materials such as foamed plastics and honeycomb for internal application in couch-support systems, yielding metal elements as part of the structure of capsules or as alternates for oleos in landing-gear struts, inflatable bags, braking rockets, and shaped surfaces for water impact. It appears feasible to readily evaluate landing-gear systems for internal or external application in hard-surface or water landings by using computational procedures and free-body landing techniques with dynamic models. The systems investigated have shown very interesting energy-dissipation characteristics over a considerable range of landing parameters. Acceptable gear can be developed along lines similar to those presented if stroke requirements and human-tolerance limits are considered.

  20. Man-machine cooperation in advanced teleoperation

    NASA Technical Reports Server (NTRS)

    Fiorini, Paolo; Das, Hari; Lee, Sukhan

    1993-01-01

    Teleoperation experiments at JPL have shown that advanced features in a telerobotic system are a necessary condition for good results, but that they are not sufficient to assure consistently good performance by the operators. Two or three operators are normally used during training and experiments to maintain the desired performance. An alternative to this multi-operator control station is a man-machine interface embedding computer programs that can perform some of the operator's functions. In this paper we present our first experiments with these concepts, in which we focused on the areas of real-time task monitoring and interactive path planning. In the first case, when performing a known task, the operator has an automatic aid for setting control parameters and camera views. In the second case, an interactive path planner will rank different path alternatives so that the operator will make the correct control decision. The monitoring function has been implemented with a neural network doing the real-time task segmentation. The interactive path planner was implemented for redundant manipulators to specify arm configurations across the desired path and satisfy geometric, task, and performance constraints.

The disease progression risk depends on endogenous and exogenous factors. Indigenous communities are a high-risk group for infection and development of tuberculosis. In addition to factors such as geographical isolation, social and cultural neglect and malnutrition, susceptibility to genetic polymorphisms has been identified in them. Spinal tuberculosis is the most destructive form of the disease, which represents approximately half of all cases of skeletal tuberculosis. The case of an HIV negative, indigenous Colombian man is presented. His diagnosis was done based on clinical and image findings, and it was confirmed with the rapid molecular assay Genotype MTBDRplus® and IS6110 PCR.The culture in solid media was negative after 16 weeks. We briefly discuss the pathogenesis, diagnosis and treatment. Finally, we comment on some aspects of the situation of tuberculosis among indigenous Colombian communities.

  2. Enhanced performance for the manned maneuvering unit

    NASA Astrophysics Data System (ADS)

    Bingham, Paul E.

    We have all seen the Manned Maneuvering Unit (MMU) on television, in the newspaper, magazines and any number of other places. It is probably one of the most widely recognized articles ever put into orbit. This paper briefly describes the MMU. The description includes an overview of the controls and physical features and a discussion of the propulsion and electrical systems. Operational experience to date is briefly covered. The MMU was first used on STS 41-B for the first untethered space walk on February 7, 1984. Next usage was for the Solar Max mission on STS 41-C, followed by the retrieval of the Westar and Palapa communication satellites on mission STS 51-A in November, 1984. One of the "lessons learned" during these space operations was the need for enhanced performance by the MMU, and leads into a discussion of how that increased performance capability will be provided. Current work on a Propellant Tank Kit (PTK), which will provide enhanced performance, is shown. The PTK will provide sufficient propellant storage capability such that the MMU with PTK will have twice the previous delta velocity capability; i.e., double the MMU's maneuvering ability. Results of development testing in the NASA/JSC Weightless Environment Test Facility are included. Current status of PTK development is presented. This paper ends with a brief discussion of proposed space operations using the enhanced MMU performance in erecting space structures from the Space Shuttle, assembling and maintaining Space Station, rescue-transfer of astronauts and other space operations.

  3. Manned interplanetary missions: prospective medical problems.

    PubMed

    Grigoriev, A I; Svetaylo, E N; Egorov, A D

    1998-12-01

    The present review aimed to suggest approaches to prospective medical problems related to the health maintenance of space crews during future manned interplanetary, particularly Martian, missions up to 2-3 years with a possible stay on a planet with gravity different from that on Earth. The approaches are based on knowledge so far obtained from our analysis of the medical support of long-term orbital flights up to one year, as well as on the consideration of specific conditions of interplanetary missions. These specific conditions include not only long-term exposure to microgravity, but also a prolonged stay of unpredictable duration (2-3 years) on board a spacecraft or on a planet without direct contact with Earth, and living in a team with a risk of psychological incompatibility and the impossibility of an urgent return to Earth. These conditions necessitate a highly trained medical person in the crew, diagnostic tools and equipment, psychophysiological support, countermeasures, as well as the means for urgent, including surgical, treatment on board a spacecraft or on a planet. In this review, the discussion was focused on the following predictable medical problems during an interplanetary mission; 1) unfavorable effects of prolonged exposure to microgravity, 2) specific problems related to Martian missions, 3) medical monitoring, 4) countermeasures, 5) psychophysiological support and 6) the medical care system.

    Substantiating data developed by a NASA-industry team (NIT) for subsequent NASA decisions on the 'right' set of manned transportation elements needed for human access to space are discussed. Attention is given to the framework for detailed definition of these manned transportation elements. Identifying and defining architecture evaluation criteria, i.e., attributes, specified the amount and type of data needed for each concept under consideration. Several architectures, each beginning with today's transportation systems, were defined using representative systems to explore future options and address specific questions currently being debated. The present solutions emphasize affordability, safety, routineness, and reliability. Key issues associated with current business practices were challenged and the impact associated with these practices quantified.

  9. Apollo experience report: Manned thermal-vacuum testing of spacecraft

    NASA Technical Reports Server (NTRS)

    Mclane, J. C., Jr.

    1974-01-01

    Manned thermal-vacuum tests of the Apollo spacecraft presented many first-time problems in the areas of test philosophy, operational concepts, and program implementation. The rationale used to resolve these problems is explained and examined critically in view of actual experience. The series of 12 tests involving 1517 hours of chamber operating time resulted in the disclosure of numerous equipment and procedural deficiencies of significance to the flight mission. Test experience and results in view of subsequent flight experience confirmed that thermal-vacuum testing of integrated manned spacecraft provides a feasible, cost-effective, and safe technique with which to obtain maximum confidence in spacecraft flight worthiness early in the program.

    Review of the feasibility of manned earth orbiting laboratories in the 1980s for solving problems identified with operational communication and navigation systems. A program of experiments recommended for implementation in the 1980 to 1990 period is presented. Equipment for conducting experiments is listed. Conceptual designs of laboratories which could be carried to orbit by the forthcoming NASA Space Shuttle Orbiter and then operated on orbit by an experimenter crew are discussed. Studies of the expected benefits, together with investigations of the configurations, mission considerations, and equipment selection result in the conclusion that manned communication/navigation research laboratories in earth orbit would be practical and effective, and that the experiments performed could derive meaningful information having application to future unmanned operational systems.

    1961-01-01

    This document presents the results of the second United States manned suborbital space flight. The data and flight description presented form a continuation of the information provided at an open conference held under the auspices of the National Aeronautics and Space Administration, in cooperation with the National Institutes of Health and the National Academy of Sciences, at the U.S. Department of State Auditorium on June 6, 1961. The papers presented herein generally parallel the presentations of the first report and were prepared by the personnel of the NASA Manned Spacecraft Center in collaboration with personnel from other government agencies, participating industry, and universities. The second successful manned suborbital space flight on July 21, 1961, in which Astronaut Virgil I. Grissom was the pilot was another step in the progressive research, development, and training program leading to the study of man's capabilities in a space environment during manned orbital flight. Data and operational experiences gained from this flight were in agreement with and supplemented the knowledge obtained from the first suborbital flight of May 5, 1961, piloted by Astronaut Alan B. Shepard, Jr. The two recent manned suborbital flights, coupled with the unmanned research and development flights, have provided valuable engineering nd scientific data on which the program can progress. The successful active participation of the pilots, in much the same way as in the development and testing of high performance aircraft, has. greatly increased our confidence in giving man a significant role in future space flight activities. It is the purpose of this report to continue the practice of providing data to the scientific community interested in activities of this nature. Brief descriptions are presented of the Project Mercury spacecraft and flight plan. Papers are provided which parallel the presentations of data published for the first suborbital space flight.

  3. The Centauri project: Manned interstellar travel

    NASA Technical Reports Server (NTRS)

    Ciesla, Thomas M.

    1990-01-01

    The development of antimatter engines for spacecraft propulsion will allow man to expand to the nearest stellar neighbors such as the Alpha Centuri system. Compared to chemically powered rockets like the Apollo mission class which would take 50,000 years to reach the Centauri system, antimatter propulsion would reduce one way trip time to 30 years or less. The challenges encountered by manned interstellar travel are formidable. The spacecraft must be a combination of sublight speed transportation system and a traveling microplanet serving an expanding population. As the population expands from the initial 100 people to approximately 300, the terraformed asteroid, enclosed by a man-made shell will allow for expansion over its surface in the fashion of a small terrestrial town. All aspects of human life - birth; death; physical, emotional, and educational needs; and government and law must be met by the structure, systems, and institutions on-board.

    1982-01-01

    The start of the Third Millennium will be highlighted by the establishment of man's extraterrestrial civilization with three technical cornerstones leading to the off-planet expansion of the human resource base. These are (1) the availability of compact energy sources for power and propulsion, (2) the creation of permanent manned habitats in space, and (3) the ability to process materials anywhere in the Solar System. In the 1990s and beyond, nuclear reactors could represent the prime source of both space power and propulsion. The manned and unmanned space missions of tomorrow will demand first kilowatt and then megawatt levels of power. Various nuclear power plant technologies will be discussed, with emphasis on derivatives from the nuclear rocket technology.

  5. The cost of landing man on Mars

    NASA Technical Reports Server (NTRS)

    Mandell, H. C., Jr.

    1984-01-01

    In a period where the space program budget is generally static at about 1/3 of the level reached during the Apollo program, manned planetary flight is not considered by NASA planners to be a realistic near term goal. Much of NASA's current planning is based on the perception that manned planetary flight would be more costly than the Apollo lunar landing. This paper demonstrates that with current technological improvements in avionics, structure, and space transportation, the landing of an American on Mars would cost only 1/3 to 2/3 of the lunar landing; on a per capita basis such a program would cost less than $200, compared to Apollo's $325 (all dollars in 1981 base). Given the fact that a manned Mars landing is the last such exploration feat left to this generation, the cost should clearly not be a major deterrent.

    Pluvial lake deposits are found throughout western North America and are frequently used to reconstruct regional paleoclimate. In Death Valley, California, USA, we apply the beach particle technique (BPT) of Adams (2003), Sedimentology, 50, 565-577 and Adams (2004), Sedimentology, 51, 671-673 to Lake Manly deposits at the Beatty Junction Bar Complex (BJBC), Desolation Canyon, and Manly Terraces and calculate paleowind velocities of 14-27 m/s. These wind velocities are within the range of present-day wind velocities recorded in the surrounding area. Sedimentary structures and clast provenance at Desolation Canyon and the Manly Terraces indicate sediment transport from north to south. Lake level, based on the elevation of constructional features, indicates that the hill west of the BJBC was an island and that the BJBC spits formed during simple lake regression. The data are consistent with the hypothesis that the present wind regime (velocity and direction) formed the pluvial Lake Manly features.

    NASA's Constellation Program is developing its next generation manned space systems for missions to the International Space Station (ISS) and the Moon. The Program is embarking on a path towards standards based Internet Protocol (IP) networking for space systems communication. The IP based communications will be paired with industry standard security mechanisms such as Internet Protocol Security (IPsec) to ensure the integrity of information exchanges and prevent unauthorized release of sensitive information in-transit. IPsec has been tested in simulations on the ground and on at least one Earth orbiting satellite, but the technology is still unproven in manned space mission situations and significant obstacles remain.

  11. Further diagnostic thoughts about the Elephant Man.

    PubMed

    Cohen, M M

    1988-04-01

    Further evidence for a diagnosis of the Elephant Man's condition is reviewed. It is known that the Elephant Man had "mocassin" lesions, hyperostoses of the skull, and absence of café-au-lait spots, all of which are characteristic of Proteus syndrome. Recently, questions have been raised about his skeletal findings and their relevance to neurofibromatosis. However, other skeletal diagnoses have been entertained, including Maffucci syndrome, Paget's disease of bone, pyarthrosis, and fibrous dysplasia. These diagnostic possibilities are discussed and evaluated critically. It is concluded that the skeletal findings are most consistent with Proteus syndrome and coincidental hip disease secondary to childhood trauma.

  17. An Assessment of Environmental Health Needs for Manned Spacecraft

    NASA Technical Reports Server (NTRS)

    2013-01-01

    Environmental health fundamentally addresses the physical, chemical, and biological risks external to the human body that can impact the health of a person by assessing and controlling these risks in order to generate and maintain a health-supportive environment. Environmental monitoring coupled with other measures including active and passive controls and the implementation of environmental standards (SMACs, SWEGs, microbial and acoustics limits) are used to ensure environmental health in manned spacecraft. NASA scientists and engineers consider environmental monitoring a vital component to an environmental health management strategy for maintaining a healthy crew and achieving mission success. Environmental monitoring data confirms the health of ECLS systems, in addition to contributing to the management of the health of human systems. Crew health risks associated with the environment were reviewed by agency experts with the goal of determining risk-based environmental monitoring needs for future NASA manned missions. Once determined, gaps in knowledge and technology, required to address those risks, were identified for various types of Exploration missions. This agency-wide assessment of environmental health needs will help guide the activities/hardware development efforts to close those gaps and advance the knowledge required to meet NASA manned space exploration objectives. Details of this assessment and findings are presented in this paper.

    1997-05-01

    The research introduces MARTI (man-machine animation real-time interface) for the realization of natural human-machine interfacing. The system uses simple vocal sound-tracks of human speakers to provide lip synchronization of computer graphical facial models. We present novel research in a number of engineering disciplines, which include speech recognition, facial modeling, and computer animation. This interdisciplinary research utilizes the latest, hybrid connectionist/hidden Markov model, speech recognition system to provide very accurate phone recognition and timing for speaker independent continuous speech, and expands on knowledge from the animation industry in the development of accurate facial models and automated animation. The research has many real-world applications which include the provision of a highly accurate and 'natural' man-machine interface to assist user interactions with computer systems and communication with one other using human idiosyncrasies; a complete special effects and animation toolbox providing automatic lip synchronization without the normal constraints of head-sets, joysticks, and skilled animators; compression of video data to well below standard telecommunication channel bandwidth for video communications and multi-media systems; assisting speech training and aids for the handicapped; and facilitating player interaction for 'video gaming' and 'virtual worlds.' MARTI has introduced a new level of realism to man-machine interfacing and special effect animation which has been previously unseen.

The toolbox, written in Python, can be used to evaluate seismic velocities of new mineral physics data or geodynamic models, and as the forward model in inversions for mantle composition. The user can define the composition from a list of minerals provided for the lower mantle or easily include their own. BurnMan provides choices in methodology, both for the EoS and for the multiphase averaging scheme. The results can be visually or quantitatively compared to observed seismic models. Example user scripts show how to go through these steps. This paper includes several examples realized with BurnMan: First, we benchmark the computations to check for correctness. Second, we exemplify two pitfalls in EoS modeling: using a different EoS than the one used to derive the mineral physical parameters or using an incorrect averaging scheme. Both pitfalls have led to incorrect conclusions on lower mantle composition and temperature in the literature. We further illustrate that fitting elastic velocities separately or jointly leads to different Mg/Si ratios for the lower mantle. However, we find that, within mineral physical uncertainties, a pyrolitic composition can match PREM very well. Finally, we find that uncertainties on specific input parameters result in a considerable amount of variation in both magnitude and gradient of the seismic velocities.

    Malignant breast lymphoma is a rare condition and primary breast lymphoma is extremely rare in the male population. We present a case of a 26-year-old man (transgender) who presented with a large palpable mass in the right breast. This mass was rapidly growing in size associated with right axillary lymphadenopathy. Ultrasound and MRI findings were consistent with BIRADS IV lesion which was suspicious of malignancy. Core biopsy was performed and histopathology confirmed the diagnosis of primary non Hodgkin B cell lymphoma of the breast.

    This case illustrates some of the issues that may affect a Latino patient’s presentation. Although the patient’s constellation of symptoms are classically representative of major depression, the patient also raises themes regarding the process of immigration, subsequent challenges in acculturation and identification with the host culture versus the culture of origin, and culture-specific notions about causes of symptoms. In addition to some of the special features of stigma in Latino cultures, the prominence of physical concerns in the presentation and the use of traditional healers contribute to the complexity of selecting appropriate interventions for this young man.

    Eccrine Angiomatous Hamartoma (EAH) is a benign rare skin neoplasm characterised histologically by abnormal proliferation of sweat glands and surrounding capillaries and other dermal elements like fatty lobules and hair. It usually presents at birth or in early childhood in the form of solitary nodules mostly affecting the extremities. Here, we report a case of angiomatous hamartoma over the face which presented as a cystic swelling in preauricular region in a 55-year-old man. The late onset and a rare site for presentation of EAH prompted us to report the case. There is not even a single case of EAH arising in the “preauricular” region, reported. PMID:27790478

    A 58-year-old male farmer, with no significant history of any chronic morbidity, was admitted via the Emergency Department of SMHS Hospital, Srinagar, with a history of an injury to the hand 20 days earlier followed by a three-day history of dysmasesis (difficulty chewing), progressing to trismus and generalized stiffness interfering with his daily activities. The patient was clinically managed as tetanus on grounds of high clinical suspicion. The patient was treated for a week and discharged without any sequelae to follow-up in the Neurology Outpatient Department of the SMHS Hospital and is currently doing well. After a week of successful management, we received the blood and wound culture reports of the patient that had been sent at the time of his admission to the hospital, which overwhelmingly tested positive for Clostridium tetani. Tetanus is a disease to be suspected post-trauma in patients, especially in developing countries like India. Despite active and passive immunization, it continues to be a significant public health problem in developing countries and should be readily suspected and treated. Although prevention is important for tetanus, the outcomes can be improved by early clinical diagnosis and treatment. PMID:27433422

  16. [Albert Schweitzer. The man as a symbol].

    PubMed

    Urdaneta-Carruyo, Eliexer

    2007-01-01

    Albert Schweitzer, the great missionary physician from the XXth century, had a versatile personality that integrated multiple talents, leading to the slightly frequent conjunction of the thinker with the man of action, and the humanist with the scientist and the artist. He studied all these disciplines in a brilliant manner: Philosophy, Theology, Music and Medicine; he was also a great scholar of Bach's work, Jesus Christ and the civilization history. In his maturity, this great man renounced to the fame and glory gained as intellectual and musician, to dedicate his life as a physician for the forgotten African natives. His deeply religious spirit allowed him to penetrate into the most recondite of the human soul; in his personality, he expressed in its entire dimension the eternally unsatisfied desire of the solitary man, against the immensity of the universe. His philosophy, based on the respect for life, was realized throughout the practice of the medical profession. His noble character and personality was based on the man as symbol, since it was not so much what he did helping people but what people could do to others due to him. His singular example represented a moral force in the world, superior to millions of men armed for a war. In 1953, he received the Nobel Peace Prize for his philanthropic work in Africa during more that fifty years, and for his deep love to the living beings. He was transformed in a perennial legend as the Lambaréné doctor.

  1. Animals, disease, and man: making connections.

    PubMed

    Hardy, Anne

    2003-01-01

    The intricate causal relationships between disease in man and disease in animals first began to be elucidated in the mid-19th century. Although the connections between animal and human disease are now generally understood, individuals as well as societies remain slow to act on this knowledge. This paper examines the gradual recognition of these disease connections and explores the parallel theme of man's reluctance to appreciate the implications of these connections. It identifies factors that have inhibited the realization of the links between disease in man and animals, and discusses several milestones in the scientific elucidation of these links. Beginning with emerging concerns over the relationship between bovine and human tuberculosis in the 1860s, it follows the discovery of insect vectors, animal reservoirs, and the links between animals, influenza, and man. Despite warnings of the potential significance for human disease of patterns of changes in the relationship with animals and the natural world, scientists have continued to treat human and animal health as largely independent disciplines, while historians too have neglected this important aspect of human disease.

    1992-10-01

    Since the first U.S. manned entry, Mercury (May 5, 1961), seventy-five manned entries have been made resulting in significant progress in the understanding and development of Thermal Protection Systems (TPS) for manned rated spacecraft. The TPS materials and systems installed on these spacecraft are compared. The first three vehicles (Mercury, Gemini, Apollo) used ablative (single-use) systems while the Space Shuttle Orbiter TPS is a multimission system. A TPS figure of merit, unit weight lb/sq ft, illustrates the advances in TPS material performance from Mercury (10.2 lb/sq ft) to the Space Shuttle (1.7 lb/sq ft). Significant advances have been made in the design, fabrication, and certification of TPS on manned entry vehicles (Mercury through Shuttle Orbiter). Shuttle experience has identified some key design and operational issues. State-of-the-art ceramic insulation materials developed in the 1970's for the Space Shuttle Orbiter have been used in the initial designs of aerobrakes. This TPS material experience has identified the need to develop a technology base from which a new class of higher temperature materials will emerge for advanced space transportation vehicles.

  10. How was the Turin Shroud Man crucified?

    PubMed

    Bevilacqua, M; Fanti, G; D'Arienzo, M; Porzionato, A; Macchi, V; De Caro, R

    2014-12-01

    As the literature is not exhaustive with reference to the way the Turin Shroud (TS) Man was crucified, and it is not easy to draw significant information from only a "photograph" of a man on a linen sheet, this study tries to add some detail on this issue based on both image processing of high resolution photos of the TS and on experimental tests on arms and legs of human cadavers. With regard to the TS Man hands, a first hypothesis states that the left hand of the TS Man was nailed twice at two different anatomical sites: the midcarpal joint medially to the pisiform between the lunate/pyramidal and capitate/uncinate bones (Destot's space) and the radiocarpal joint between the radio, lunate and scaphoid; also the right hand would have been nailed twice. A second hypothesis, preferred by the authors, states that the hands were nailed only once in the Destot's space with partial lesion of the ulnar nerve and flexion of the metacarpophalangeal joint of the thumbs. With regard to the TS Man feet, the imprint of the sole of the right foot leads to the conclusion that TS Man suffered a dislocation at the ankle just before the nailing. The entrance hole of the nail on the right foot is a few inches from the ankle, and excludes a double nailing. The nail has been driven between the tarsal bones. The TS Man suffered the following tortures during crucifixion: a very serious and widespread causalgia due to total paralysis of the upper right limb (paradoxical causalgia); a nailing of the left wrist with damage to the ulnar nerve; a similar nailing of the right wrist; and a nailing to both feet using one only nail that injured the plantaris medialis nerves. The respiratory limitation was probably not sufficient to cause death by asphyxiation. Also considering the hypovolemia produced by scourging and the many other tortures detectable on the TS, the principal cause of death can be attributed to a myocardial infarction.

  11. Manned Spacecraft Landing and Recovery

    NASA Technical Reports Server (NTRS)

    Hammel, Don

    2004-01-01

    As recent history has tragically demonstrated, a successful space mission is not complete until the crew has safely returned to earth and has been successfully recovered. It is noted that a safe return to earth does not guarantee a successful recovery. The focus of this presentation will be a discussion of the ground operation assets involved in a successful recovery. The author's experience in land and water-based recovery of crewed vehicles and flight hardware at Kennedy Space Center (KSC), Edwards Air Force Base, international landing sites, and the Atlantic Ocean provides for some unique insight into this topic. He has participated in many aspects of Space Shuttle landing and recovery operations including activation of Transatlantic Abort Landing (TAL) sites and Emergency Landing Sites (ELS) as an Operations Test Director, execution of post landing convoy operations as an Orbiter Move Director, Operations Test Director, and Landing and Recovery Director, and recovery of solid rocket boosters, frustum and their parachutes 140 miles offshore in a wide range of sea states as a Retrieval Diver/Engineer. The recovery operations for the Mercury, Gemini, and Apollo were similar from a landing and recovery perspective in th t they all were capsules with limited "flying" capability and had a planned End of Mission (EOM) in an ocean with a descent slowed by parachutes. The general process was to deploy swim teams via helicopters to prepare the capsule for recovery and assist with crew extraction when required. The capsule was then hoisted onto the deck of a naval vessel. This approach required the extensive use and deployment of military assets to support the primary landing zone as well as alternate and contingency locations. The Russian Soyuz capsule also has limited "flying" capability; however, the planned EOM is terrestrial. In addition to use of parachutes to slow the reentry descent, soft-landing rockets on the bottom of the vehicle are employed to cushion the

    Novelo-Casanova, D. A.; Suarez, G.

    2010-12-01

    Located in the western Caribbean Sea to the northwest of Jamaica, the Cayman Islands are a British overseas territory comprised of three islands: Grand Cayman, Cayman Brac, and Little Cayman. These three islands occupy around 250 km2 of land area. In this work, historical and recent data were collected and classified to identify and rank the natural and man-made hazards that may potentially affect the Cayman Islands and determine the level of exposure of Grand Cayman to these events. With this purpose, we used the vulnerability assessment methodology developed by the North Caroline Department of Environment and Natural Resources. The different degrees of physical vulnerability for each hazard were graphically interpreted with the aid of maps using a relative scoring system. Spatial maps were generated showing the areas of different levels of exposure to multi-hazards. The more important natural hazard to which the Cayman Islands are exposed is clearly hurricanes. To a lesser degree, the islands may be occasionally exposed to earthquakes and tsunamis. Explosions or leaks of the Airport Texaco Fuel Depot and the fuel pipeline at Grand Cayman are the most significant man-made hazards. Our results indicate that there are four areas in Grand Cayman with various levels of exposure to natural and man-made hazards: The North Sound, Little Sound and Eastern West Bay (Area 1) show a very high level of exposure; The Central Mangroves, Central Bodden Town, Central George Town and the West Bay (Area 2) have high level of exposure; The Northwestern West Bay, Western Georgetown-Bodden Town, and East End-North Side (Area 3) are under moderate levels of exposure. The remainder of the island shows low exposure (Area 4). It is important to underline that this study presents a first evaluation of the main natural and man-made hazards that may affect the Cayman Islands. The maps generated will be useful tools for emergency managers and policy developers and will increase the overall

    A mathematical model of the waveform generated by man-made high frequency (HF) noise and interference is presented and discussed. The model is based on wideband (800 kHz) recordings of the noise and interference at various frequencies in the HF band. Representative examples of first- and higher-order statistics of the measured waveforms are described, including probability distributions of the envelope and phase of the noise and interference in the time and frequency domains, power spectra, autocorrelation functions, and level crossing distributions. The statistics of waveforms generated by the model closely resemble the statistics of the measured data.

    2016-01-01

    Cough is often a distressing feature and may be caused due to varied reasons. A 39-year-old man presented with complaints of cough and had significant pigeon exposure. His chest X-ray revealed mediastinal enlargement and computed tomography chest revealed air trapping and mediastinal lymphadenopathy. Both endobronchial and transbronchial biopsies revealed granulomas. Thus, the patient was diagnosed as a case of sarcoidosis and started on steroids. Hypersensitivity pneumonitis may often mimic sarcoidosis; however, the presence of endobronchial granulomas will diagnose the latter condition. PMID:27890996

    Granuloma inguinale, or Donovanosis, is a rare, sexually transmitted ulcerative disease primarily affecting the genital area. In this report, we present a case of a 50-year-old man that was diagnosed with granuloma inguinale after a 2-month history of a penile ulcer. Histological analysis demonstrated the presence of Donovan bodies within macrophages, confirming the diagnosis. He was subsequently treated with trimethoprim/sulfamethoxazole with improvement in the ulcer. This case serves as a reminder to clinicians that although granuloma inguinale is rarely encountered in the US, it should still be suspected in patients with non-healing penile ulcers.

    A 58-year-old man has been under our care with an inguinal hernia that has recurred 8 times. This stimulated us to review the biochemistry of wound repair. We studied the composition of his collagen and tried to find out whether it was intrinsically faulty or whether its fault had been caused by the medication he was taken.

  11. Physiologically constrained aerocapture for manned Mars missions

    NASA Technical Reports Server (NTRS)

    Lyne, James Evans

    1992-01-01

    Aerobraking has been proposed as a critical technology for manned missions to Mars. The variety of mission architectures currently under consideration presents aerobrake designers with an enormous range of potential entry scenarios. Two of the most important considerations in the design of an aerobrake are the required control authority (lift-to-drag ratio) and the aerothermal environment which the vehicle will encounter. Therefore, this study examined the entry corridor width and stagnation-point heating rate and load for the entire range of probable entry velocities, lift-to-drag ratios, and ballistic coefficients for capture at both Earth and Mars. To accomplish this, a peak deceleration limit for the aerocapture maneuvers had to be established. Previous studies had used a variety of load limits without adequate proof of their validity. Existing physiological and space flight data were examined, and it was concluded that a deceleration limit of 5 G was appropriate. When this load limit was applied, numerical studies showed that an aerobrake with an L/D of 0.3 could provide an entry corridor width of at least 1 degree for all Mars aerocaptures considered with entry velocities up to 9 km/s. If 10 km/s entries are required, an L/D of 0.4 to 0.5 would be necessary to maintain a corridor width of at least 1 degree. For Earth return aerocapture, a vehicle with an L/D of 0.4 to 0.5 was found to provide a corridor width of 0.7 degree or more for all entry velocities up to 14.5 km/s. Aerodynamic convective heating calculations were performed assuming a fully catalytic, 'cold' wall; radiative heating was calculated assuming that the shock layer was in thermochemical equilibrium. Heating rates were low enough for selected entries at Mars that a radiatively cooled thermal protection system might be feasible, although an ablative material would be required for most scenarios. Earth return heating rates were generally more severe than those encountered by the Apollo vehicles

    1989-01-01

    Many lobbyists in Washington have argued that artificial intelligence (AI) is an alternative to manned space activity. In actuality, this is the opposite of the truth, especially as regards artificial neural networks (ANNs), that form of AI which has the greatest hope of mimicking human abilities in learning, ability to interface with sensors and actuators, flexibility and balanced judgement. ANNs and their relation to expert systems (the more traditional form of AI), and the limitations of both technologies are briefly reviewed. A Few highlights of recent work on ANNs, including an NSF-sponsored workshop on ANNs for control applications are given. Current thinking on ANNs for use in certain key areas (the National Aerospace Plane, teleoperation, the control of large structures, fault diagnostics, and docking) which may be crucial to the long term future of man in space is discussed.

    An integrated water vapor electrolysis (WVE) hydrogen depolarized CO2 concentrator (HDC) system sized for one man support over a wide range of inlet air conditions was designed, fabricated, and tested. Data obtained during 110 days of testing verified that this system can provide the necessary oxygen, CO2 removal, and partial humidity control to support one man (without exceeding a cabin partial pressure of 3.0 mmHg for CO2 and while maintaining a 20% oxygen level), when operated at a WVE current of 50 amperes and an HDC current of 18 amperes. An evaluation to determine the physical properties of tetramethylammonium bicarbonate (TMAC) and hydroxide was made. This provides the necessary electrolyte information for designing an HDC cell using TMAC.

    A Manned Mars Mission (M3) design study is proposed. The purpose of M3 is to transport 10 personnel and a habitat with all required support systems and supplies from low Earth orbit (LEO) to the surface of Mars and, after an eight-man surface expedition of 3 months, to return the personnel safely to LEO. The proposed hardware design is based on systems and components of demonstrated high capability and reliability. The mission design builds on past mission experience, but incorporates innovative design approaches to achieve mission priorities. Those priorities, in decreasing order of importance, are safety, reliability, minimum personnel transfer time, minimum weight, and minimum cost. The design demonstrates the feasibility and flexibility of a Waverider transfer module.

  15. Hermes: A European manned space system

    NASA Astrophysics Data System (ADS)

    Cretenet, J. C.

    Designs for manned and automatic versions of the Hermes maneuverable reentry system are outlined. The reentry glider would go piggyback or the launcher's upper stage, with its own autonomous avionics. A round trip to low Earth orbit would take 10 days, with a touchdown in Europe or Guyana. The form would be similar to the NASA shuttle. Reentry trajectory would ensure a constant flux density of 500 kw/sqm on the nose, with thermal protection keeping structural temperature below 175C. Hydrogen oxygen fuel cells would be used for auxiliary power. A 15 kN propulsion unit with sixteen 400N attitude control engines would be mounted astern, and twelve 400N engines forward. Ariane 4 is not considered powerful enough for Hermes, except for low, circular orbits. Ariane 5 could take a 50 cu m hold automatic version, or 70 cu m manned.

    The ability to service satellites has thus far been limited to low earth orbit platforms within reach of the Space Shuttle. Other orbits, such as geosynchronous orbits containing high-value spacecraft have not been attainable by a servicing vehicle. The useful life of a satellite can be extended by replacing spent propellant and damaged orbital replacement units, forestalling the need for eventual replacement. This growing need for satellite on-orbits servicing can be met by the Manned On-Orbit Servicing Equipment (MOOSE). Missions requiring orbit transfer capability, precision manipulation and maneuvering, and man-in-the-loop control can be accomplished using MOOSE. MOOSE is a flexible, reusable, single operator, aerobraking spacecraft designed to refuel, repair, and service orbiting spacecraft. MOOSE will be deployed from Space Station Freedom, (SSF), where it will be stored, resupplied, and refurbished.

  17. Man-midwifery history: 1730-1930.

    PubMed

    Shelton, D C

    2012-11-01

    This paper seeks to determine whether the man-midwives William Smellie and William Hunter deserve continuing approbation as 'Founding Fathers' of the obstetrics profession. Scrutiny of their careers reveals their involvement in murders for dissection. In addition, the man-midwifery initiative of delivery in lying-in hospitals resulted in around 1 million more deaths in Britain and Ireland between 1730 and 1930, than would have occurred had home-births remained as the norm. While some may still credit Smellie and Hunter with obstetric discoveries, their knowledge was obtained by murder-for-dissection. That indictment, together with the lying-in hospital legacy, far outweighs their discoveries. The paper invites further constructive discussion and debate, but concludes the accolade of Founding Fathers is undeserved. Any continuing endorsement of Smellie and Hunter effectively demeans the high ethical standards and reputation of current obstetric professionals.

  18. Potential teleoperator applications in manned aerospace systems

    NASA Technical Reports Server (NTRS)

    Johnsen, E. G.

    1973-01-01

    The trend of teleoperator development is toward digital computer controlled systems which utilize local sensor-computer-actuator loops to avoid obstacles and to sense manipulator grip-and-slip. The potential applications of advanced teleoperator technology to manned aerospace systems include long manipulator booms to be mounted on the shuttle. These can transfer cargo from the space shuttle and can acquire and retrieve objects in space. Free-flying teleoperators capable of acquiring, inspecting, repairing or refurbishing satellites in orbit are another space application. Another potential application of teleoperator technology is the concept of using an anthropomorphous teleoperator in lieu of man to control aircraft or spacecraft normally controlled by a human pilot.

    2013-01-01

    From the analysis of its epistemological status, the article focuses on the philosophical fundament of bioethics, stressing the need for an authentic anthropology as a reference or starting point. Being an applied ethics, the first fundament of bioethics is in ethics. It shows how only personalistic ethics, which takes as reference the nature or essence of man, can offer objective and universal criteria. Philosophical anthropology studies man as a whole, in an integral manner, from the perspective of its nature or fundamental aspects of his being. It analyzes the distinction and relationship between the philosophical anthropology and the positive anthropologies, as well as with the physical, human and social sciences. Finally, it reflects on the current anthropological crisis and its ethical consequences.

    Eliminating middlemen from security protocols helps less than one would think. EMV electronic payments, for example, can be made fairer by adding an electronic attorney - a middleman which mediates access to a customer’s card. We compare middlemen in crypto protocols and APIs with those in the real world, and show that a man-in-the-middle defence is helpful in many circumstances. We suggest that the middleman has been unfairly demonised.

    2004-09-01

    The Man craton in West Africa is an Archaean craton formerly joined to the Guyana craton (South America) that was rifted apart in the Mesozoic. Kimberlites of the Man craton include three Jurassic-aged clusters in Guinea, two Jurassic-aged clusters in Sierra Leone, and in Liberia two clusters of unknown age and one Neoproterozoic cluster recently dated at ˜800 Ma. All of the kimberlites irrespective of age occur as small pipes and prolific dykes. Some of the Banankoro cluster pipes in Guinea, the Koidu pipes in Sierra Leone and small pipes in the Weasua cluster in Liberia contain hypabyssal-facies kimberlite and remnants of the so-called transitional-facies and diatreme-facies kimberlite. Most of the Man craton kimberlites are mineralogically classified as phlogopite kimberlites, although potassium contents are relatively low. They are chemically similar to mica-poor Group 1A Southern African examples. The Jurassic kimberlites are considered to represent one province of kimberlites that track from older bodies in Guinea (Droujba 153 Ma) to progressively younger kimberlites in Sierra Leone (Koidu, 146 Ma and Tongo, 140 Ma). The scarcity of diatreme-facies kimberlites relative to hypabyssal-facies kimberlites and the presence of the so-called transitional-facies indicate that the pipes have been eroded down to the interface between the root and diatreme zones. From this observation, it is concluded that extensive erosion (1-2 km) has occurred since the Jurassic. In addition to erosion, the presence of abundant early crystallizing phlogopite is considered to have had an effect on the relatively small sizes of the Man craton kimberlites.

    1993-01-10

    .A recent discovery (8/14/92) of a near-earth object containing materials potentially useful for space activities could perhaps change the entire way humans access and operate in space. A near-Earth object ([number sign]4015, 1979 VA, comet Wilson-Harrington) contains water ice that could be used for space propulsion. In addition, this type of object may contain structural and lifesustaining materials (complex hydrocarbons, ammonia and/or bound nitrogen compounds) for space structures, manned planetary bases, or planetary surface terraforming. The retrieval and utilization of rocket propellant from near-Earth objects, for manned Mars missions in particular, has been investigated and the benefits of this scenario to over performing a Mars mission with terrestrial propellants have been documented. The results show water extracted from these objects and retrieved to Earth orbit for use in going to Mars may actually enable manned Mars exploration by reducing the number of Heavy Lift Launch Vehicle (HLLV) flights or eliminating the need for HLLV's altogether. The mission can perhaps be supported with existing launch vehicles and not required heavy lift capability. Also, the development of a nuclear thermal rocket for this alternate approach may be simplified substantially by reducing the operating temperature required.

  14. Freud, evolution, and the tragedy of man.

    PubMed

    Holmes, K R

    1983-01-01

    It is argued that Freud was not, as Sulloway (1979) contends, a "crypto-biologist" of the mind, but rather a cultural anthropologist of the mind. Freud's genetic conception of the psychic apparatus was neither exclusively nor critically derived from biology. Rather, it was based on an anthropogenetic approach to the archaic heritage of mind inspired in part by the moral philosophy of Nietzsche. The idea of tragedy was the unifying theme of Freud's cultural interpretation of evolutionary psychology. The historical search for the primal origins of neurosis led Freud to the unavoidable conclusion that neurosis was in the beginning a prehistoric moral dilemma which, over the course of mental evolution, eventually evolved into guilt, discontent, and neurosis as modern-day phylogenetically endowed facts of life. Freud (1930) made it clear that the source of man's biological and cultural evolutionary progress--self-denial--was also responsible for the tragedy of the human condition, namely, repression, eternal psychic ambivalence, and chronic mental illness. He believed that neurosis began, as Nietzsche (1887) exclaimed, with the "reduction of the beast of prey 'man' to a tame and civilized animal..." (p. 42). For both Freud and Nietzsche, the cause of the human tragedy was not merely the fall from Nature, but the inexorable knowledge that Man's denial of his biological heritage was the very basis for being human.

    A 25-year-old man presented with a 2-month history of dysphagia and past history of pulmonary and intestinal tuberculosis. A barium swallow showed a point of constriction 42 mm above the gastroesophageal junction. Computed tomography revealed large opacities in bilateral lung fields, encroaching more on the esophagus. The lesion progressively compressed the esophagus as it moved inferiorly. A right posterolateral thoracotomy was performed for sub-anatomical resection of the mass. A biopsy revealed homogenous whirling hyalinized collagen fibers, highly suggestive of pulmonary hyalinizing granuloma, with no evidence of malignancy. Pulmonary hyalinizing granuloma should be considered in the differential diagnosis of longstanding dysphagia.

  8. Man-made objects cuing in satellite imagery

    SciTech Connect

    Skurikhin, Alexei N

    2009-01-01

    We present a multi-scale framework for man-made structures cuing in satellite image regions. The approach is based on a hierarchical image segmentation followed by structural analysis. A hierarchical segmentation produces an image pyramid that contains a stack of irregular image partitions, represented as polygonized pixel patches, of successively reduced levels of detail (LOOs). We are jumping off from the over-segmented image represented by polygons attributed with spectral and texture information. The image is represented as a proximity graph with vertices corresponding to the polygons and edges reflecting polygon relations. This is followed by the iterative graph contraction based on Boruvka's Minimum Spanning Tree (MST) construction algorithm. The graph contractions merge the patches based on their pairwise spectral and texture differences. Concurrently with the construction of the irregular image pyramid, structural analysis is done on the agglomerated patches. Man-made object cuing is based on the analysis of shape properties of the constructed patches and their spatial relations. The presented framework can be used as pre-scanning tool for wide area monitoring to quickly guide the further analysis to regions of interest.

  9. The fate of Don Juan: the myth and the man.

    PubMed

    Brockman, D D

    1992-01-01

    The literary character of Don Juan has offered an opportunity to study certain characteristics in an adult man who began a behavior pattern in adolescence that resembled the legendary and mythical Don Juan. Power and dominating control issues were paramount defenses against a narcissistic depression in this man as seen in his relationships with women and in the transference relationship with me. The transference data have been put to use in providing a formulation for an explanation of the phenomena observed. Other clinical data concerning women and some homosexual men are presented in a more abbreviated fashion. This research effort is a retrospective construction of the dynamics that led to this man's neurosis. In my opinion, a self psychological interpretation offers the more felicitous fit than the classic oedipal interpretation. In fact, at first I tried interpretations based on classic oedipal theory--concerning issues of competition with me as father and fear of retaliation and castration--but this strategy resulted in little or no response. More important than symptomatic response, however, the data minimally and weakly supported those interpretations. To be sure, there were and still are competitive and phallic oedipal issues. Moreover, when the patient's mother died, he was drawn into a closer relationship with his father, a relationship accompanied by wishes and fantasies of taking his mother's place. These wishes were quite real, but, as the analysis preceeded, this negative oedipal configuration occupied a much less prominent place in the dynamics. Power and control issues dominated the clinical picture, masking a depression emanating from a deeper narcissistic focus. Interpretation of these narcissistic issues provided my patient with the relief he was seeking, while the main effect of the antidepressant medication was to help him sleep. By giving him something, a deeply seated wish was gratified and was in keeping with an idealized mother

  13. Portal Hypertension and Ascites Due to an Arterioportal Fistula: Sequela of a Remote Traumatic Liver Laceration

    PubMed Central

    Hulkower, Benjamin M.; Butty, Sabah

    2016-01-01

    Arterioportal fistulas (APFs) are a group of vascular disorders, in which systemic arteries communicate with the portal circulation, presenting as a congenital syndrome or more commonly acquired from iatrogenic instrumentation or abdominal trauma. We report the case of a 58-year-old man who developed ascites without underlying risk factors for portal hypertension, which was attributed to an APF found on imaging, manifesting 43 years after sustaining a liver laceration. After angiographic embolization of the APF, the patient’s ascites resolved completely. The prolonged latent period between the patient’s abdominal trauma and eventual presentation with ascites highlights the need to consider vascular malformations in the differential diagnosis of unexplained noncirrhotic portal hypertension.

    2010-01-01

    A 58-year-old man presented with a 6-month history of progressive cervical myelopathy. Magnetic resonance imaging and computed tomography of the cervical spine revealed a bone tumor arising from the posterior arch of the atlas and osteophytes at a pseudoarthrosis between the tumor and the lamina of the axis, resulting in marked spinal cord compression. The patient's symptoms resolved after en bloc resection of the tumor and removal of the osteophytes. The histological diagnosis was osteochondroma. The primary cause of myelopathy in the present case was osteochondroma arising from the posterior arch of the atlas, but the osteophyte formations appearing at the pseudoarthrosis between the atlas osteochondroma and the lamina of the axis might also have contributed to the symptoms, which appeared when the patient was in his late 50s.

    2016-01-01

    We present the case of a 58-year-old man who underwent urgent blowhole colostomy for toxic megacolon (TM) secondary to Clostridium difficile infection (CDI). This infection occurred under antibiotic coverage with amoxicillin-clavulanic acid, four days after laparoscopic sigmoidectomy in our hospital. Although prospective clinical research regarding the surgical management of TM is lacking, decompressive procedures like blowhole colostomy are reported to carry a high risk of postoperative morbidity and mortality and are widely regarded as obsolete. Subtotal or total colectomy with end ileostomy is currently considered the procedure of choice. After presenting our case, we discuss the literature available on the subject to argue that the scarce evidence on the optimal surgical treatment for TM is primarily based on TM associated with inflammatory bowel diseases (IBD) and that there might be a rationale for considering minimally invasive procedures like blowhole colostomy for CDI-associated TM.

    The Taurus Lightweight Manned Spacecraft (LMS) was developed by students of the University of Maryland's Aerospace Engineering course in Space Vehicle Design. That course required students to design an Alternative Manned Spacecraft (AMS) to augment or replace the Space Transportation System and meet the following design requirements: (1) launch on the Taurus Booster being developed by Orbital Sciences Corporation; (2) 99.9 percent assured crew survival rate; (3) technology cutoff data of 1 Jan. 1991; (4) compatibility with current space administration infrastructure; and (5) first flight by May 1995. The Taurus LMS design meets the above requirements and represents an initial step towards larger and more complex spacecraft. The Taurus LMS has a very limited application when compared to the Space Shuttle, but it demonstrates that the U.S. can have a safe, reliable, and low cost space system. The Taurus LMS is a short mission duration spacecraft designed to place one man into low earth orbit (LEO). The driving factor for this design was the low payload carrying capabilities of the Taurus Booster--1300 kg to a 300 km orbit. The Taurus LMS design is divided into six major design sections. The human factors system deals with the problems of life support and spacecraft cooling. The propulsion section contains the abort system, the Orbital Maneuvering System (OMS), the Reaction Control System (RCS), and power generation. The thermal protection systems and spacecraft structure are contained in the structures section. The avionics section includes navigation, attitude determination, data processing, communication systems, and sensors. The mission analysis section was responsible for ground processing and spacecraft astrodynamics. The systems integration section pulled the above sections together into one spacecraft and addressed costing and reliability.

    1984-01-01

    Although both the epidemiologic and experimental studies have led to the identification of chemical carcinogens, the limitations in epidemiologic approaches and the need for primary prevention of cancer require a greater reliance on experimental studies. Long-term carcinogenicity studies in experimental animals have been instrumental in identifying chemicals with carcinogenic activity, and, in some cases, the experimental evidence has preceded the epidemiologic evidence (for 4-aminobiphenyl, aflatoxin B1, diethylstilbestrol, melphalan, mustard gas, and vinyl chloride). A better understanding of the multistage process of carcinogenesis and the findings from various short-term tests available more recently may provide a more solid basis for extrapolating experimental findings to man.

The properties of the waves recordable within the interval from 1 to 10 msec after the stimuli strike the eardrum are discussed along with factors influencing the waves in the 100 to 500 msec epoch. So-called brainstem responses from a normal young adult are considered. No waves were observed for clicks to weak to be heard. With increasing stimulus strength the waves become larger in amplitude and their latency shortens.

    Building manned lunar base is one of the core aims of human lunar exploration project, which is also an important way to carry out the exploitation and utilization of lunar in situ resources. The most important part of manned lunar base is the design and construction of living habitation and many factors should be considered including science objective and site selection. Through investigating and research, the scientific goals of manned lunar base should be status and characteristics ascertainment of lunar available in situ resources, then developing necessary scientific experiments and utilization of lunar in situ resources by using special environment conditions of lunar surface. The site selection strategy of manned lunar base should rely on scientific goals according to special lunar surface environment and engineering capacity constraints, meanwhile, consulting the landing sites of foreign unmanned and manned lunar exploration, and choosing different typical regions of lunar surface and analyzing the landform and physiognomy, reachability, thermal environment, sunlight condition, micro meteoroids protection and utilization of in situ resources, after these steps, a logical lunar living habitation site should be confirmed. This paper brings out and compares three kinds of configurations with fabricating processes of manned lunar base, including rigid module, flexible and construction module manned lunar base. 1.The rigid habitation module is usually made by metal materials. The design and fabrication may consult the experience of space station, hence with mature technique. Because this configuration cannot be folded or deployed, which not only afford limit working and living room for astronauts, but also needs repetitious cargo transit between earth and moon for lunar base extending. 2. The flexible module habitation can be folded in fairing while launching. When deploying on moon, the configuration can be inflatable or mechanically-deployed, which means under

A zippered opening in the floor allows entry and facilitates the use of a constant diameter tube. An airtight fabric bulkhead divides the peripheral tube longitudinally into inflatable tube sections, where if either tube section were punctured, the bulkhead would move into the punctured section to substitute for the punctured wall portion and maintain the inflatable volume of the tube. The floor member is attached to the central portion of the tube wall so that either side of the raft can be the up side.

    Inasmuch as orf, milker's nodules and bovine papular stomatitis pox are clinically identical in man and are induced by currently indistinguishable parapox viruses, we propose a new generic term 'farmyard pox' for these diseases. This affords the clinician a diagnosis based on a common set of clinical and electron microscopic findings rather than one based on an uncertain or even misleading history. A case in point is reported in which the history failed to reveal a specific animal source of the virus, but electron microscopy confirmed the presence of parapox infection.

    The kinetochore, located at the primary constriction or centromere in mammalian metaphase chromosomes, is the site of attachment of spindle microtubules to the mitotic chromosome, and is thus essential for correct chromosome movement and segregation at anaphase. Errors in organization of the kinetochore and/or centromere may therefore lead to non-disjunction and aneuploidy. The centromeres of most, if not all, mammalian chromosomes contain repetitive DNA sequences, which are observed at the cytogenetic level as heterochromatin. We have combined immunofluorescence with primed in situ hybridization (PRINS) techniques to study the organization of repetitive DNA families in relation to chromosomal proteins located at centromeres in both man and mouse species.

    Although there is a long history of consanguineous marriage in China, information on its prevalence is very limited. The Man (Qing) dynasty ruled China for over 250 years, but no consanguinity studies have been reported on this important population. The objective of the present investigation was to determine the present-day level of consanguineous marriage in the Man community, and to compare the data with existing consanguinity information on other Chinese populations. The study was conducted in a group of 11 rural Man communities in the north-eastern Chinese province of Liaoning. Household-based interviews were conducted by local staff on 513 couples, 418 of whom were Man with another 95 Man-Han inter-ethnic marriages. Basic pedigrees were constructed to determine the biological relationship between each set of spouses. Thirty of the 418 couples were in a consanguineous union, with a mean coefficient of inbreeding alpha = 0.0012. The small population sizes of the study may have contributed to the spatial variation in the patterns of inbreeding. Across generations there was a reduction in consanguineous marriages and an increase in inter-ethnic unions, which paralleled changes in civil marriage regulations.

    1976-02-01

    The role of glucagon in regulating peripheral tissue metabolism in man was assessed in the present studies. To do this, glucagon was infused for two hours into the brachial artery to produce a high but physiologic increment in the glucagon content of arterial blood supplying ipsilateral tissues. Metabolic effects on muscle and on subcutaneous adipose tissue plus skin were sought in seven overnight-fasting subjects and seven subjects starved briefly (60 hours). In the overnight-fasted group the infusion increased bassl glucagon concentration by 1,216 pg./ml. but was without effect on forearm tissue metabolism of glucose, lactate,glycerol, or amino acids. Starvation significantly reduced basal insulin (11.0 to 7.4 muU./ml.) and increased endogenous glucagon (116 to 134 pg./ml.). Basally, there was substantial ketone utilization and a decrease in glucose consumption by both muscle and subcutaneous adipose tissue plus skin. The glucagon infusion increased basal glucagon by 784 pg./ml. Muscle balances of glucose, lactate, acetoacetate, amino acids, and glycerol were unaffected. The metabolism of glucose, lactate, acetoacetate, glycerol, and free fatty acids by subcutaneous adipose tissue plus skin was also unchanged. It is concluded that physiologic increments of glucagon lasting two hours are without effect on forearm tissues in overnight-fasted and briefly starved man.

    2014-01-01

    The author has collaborated with NASA astronauts, scientists and engineers since 2006. Manned deep space missions, beyond the Moon’s orbit, are being planned in this post-Shuttle era. The spacecraft required for longer flights will have relatively restricted crew interior volume. To decrease the negative impact of these tight quarters, the author has proposed recruiting smaller astronauts (abbreviated SAs), persons about one-half the height of current near-Earth crewmembers. This includes achondroplastic dwarfs, lower extremity amputees and persons with certain height-reducing birth defects such as phocomelia. To overcome issues of physical competence, strength and mobility of SAs, the author describes using advanced cybernetic prostheses for those with limb amputations or deformities, and motorized exoskeletons for the others. Muscle and bone-sparing space exercise programs for SAs should be simpler. For example, a motorized exoskeleton used for routine duties in space would also provide both resistance workouts and passive range of motion conditioning for the astronauts, even while resting. Complex personalized artificial intelligence functions may be added. These initial suggestions previously presented to NASA offer a starting point for deep space manned missions to the asteroid belt, Mars and beyond.

    Epidermal growth factor (EGF) is localised in man to salivary and Brunner's glands. It is present in large concentrations in saliva and duodenal contents but the mechanisms of its release have been little studied. This study carried out on four groups of healthy subjects was designed to determine the distribution and the release of immunoreactive EGF (IR-EGF) in salivary, gastric, duodenal, and pancreatic secretions. Under basal conditions, the concentrations of IR-EGF in salivary, gastric, duodenal and pancreatic secretions were; 2.7 (0.4), 0.42 (0.12), 21 (5) and 8.5 (1.2) ng/ml, respectively. Chewing of Parafilm* significantly increased salivary but not gastric or duodenal EGF output while atropinisation led to the reduction in basal salivary and duodenal EGF output without affecting the increment in EGF release induced by chewing. Cigarette smoking caused a marked reduction in basal salivary and duodenal EGF output. Infusion of pentagastrin increased salivary and duodenal EGF output and this was blocked by the addition of somatostatin. Injection of secretin lead to an increase in pancreatic output of EGF. We conclude that in man the major sources of EGF are salivary glands, duodenum, and pancreas and that the release of EGF remains under neurohormonal control. PMID:2806986

    RNA is highly sensitive to the ionic environment, and typically requires Mg2+ to form compact structures. There is a need for models capable of describing the ion atmosphere surrounding RNA with quantitative accuracy. We present a model of RNA electrostatics and apply it within coarse-grained molecular dynamics simulation. The model treats Mg2+ ions explicitly to account for ion-ion correlations neglected by mean field theories. Since mean-field theories capture KCl well, it is treated implicitly by a generalized Manning counterion condensation model. The model extends Manning condensation to deal with arbitrary RNA conformations, non-limiting KCl concentrations, and the ion inaccessible volume of RNA. The model is tested against experimental measurements of the excess Mg2+ associated with the RNA, Γ2+, because Γ2+ is directly related to the Mg2+-RNA interaction free energy. The excellent agreement with experiment demonstrates the model captures the ionic dependence of the RNA free energy landscape. PMID:26197147

  15. A proof of the Kontsevich-Soibel'man conjecture

    It is well known that the 'Fukaya category' is actually an A{sub {infinity}-}precategory in the sense of Kontsevich and Soibel'man. This is related to the fact that, generally speaking, the morphism spaces are defined only for transversal pairs of Lagrangian submanifolds, and higher multiplications are defined only for transversal sequences of Lagrangian submanifolds. Kontsevich and Soibel'man made the following conjecture: for any graded commutative ring k, the quasi-equivalence classes of A{sub {infinity}-}precategories over k are in bijection with the quasi-equivalence classes of A{sub {infinity}-}categories over k with strict (or weak) identity morphisms. In this paper this conjecture is proved for essentially small A{sub {infinity}-}(pre)categories when k is a field. In particular, this implies that the Fukaya A{sub {infinity}-}precategory can be replaced with a quasi-equivalent actual A{sub {infinity}-}category. Furthermore, a natural construction of the pretriangulated envelope for A{sub {infinity}-}precategories is presented and it is proved that it is invariant under quasi-equivalences.

    2016-01-01

    The current ISS Water Recovery System (WRS) reclaims water from crew urine, humidity condensate, and Sabatier product water. Urine is initially processed by the Urine Processor Assembly (UPA) which recovers 75% of the urine as distillate. The remainder of the water is present in the waste brine which is currently disposed of as trash on ISS. For future missions this additional water must be reclaimed due to the significant resupply penalty for missions beyond Low Earth Orbit (LEO). NASA has pursued various technology development programs for a brine processor in the past several years. This effort has culminated in a technology down-select to identify the optimum technology for future manned missions. The technology selection is based on various criteria, including mass, power, reliability, maintainability, and safety. Beginning in 2016 the selected technology will be transitioned to a flight hardware program for demonstration on ISS. This paper summarizes the technology selection process, the competing technologies, and the rationale for the technology selected for future manned missions.

  17. An algorithm for nasal pungency thresholds in man.

    Nasal pungency thresholds (NPT) in man have been determined by Cometto-Muniz and Cain for 44 varied compounds, including esters, aldehydes, ketones, alcohols, carboxylic acids, aromatic hydrocarbons and pyridine. With the exclusion of acetic acid, 43 of these NPT values are well correlated through the general linear free energy equation of Abraham, leading to the algorithm, log(1/NPT) = -8.519 + 2.154 pi(2)H + 3.522 sigma alpha(2)H + 1.397 sigma beta(2)H + 0.860 logL16. N = 43, r2 = 0.955, SD = 0.27, F = 201 (i) where the independent variables are solute descriptors: pi(2)H is the dipolarity/polarizability, sigma alpha(2)H and sigma beta(2)H are the overall or effective hydrogen-bond acidity and basicity, and L16 is the solute Ostwald solubility coefficient on hexadecane at 25 degrees C. Surprisingly, the aliphatic aldehydes and carboxylic acids fit the correlation and with respect to nasal pungency thresholds in man for brief (1-3 s) presentations must be regarded as 'nonreactive' compounds. It is suggested mere transport of the compound from the air stream to the receptor area largely determines the potency to produce pungency. Various chemical properties of the receptor area are deduced from the coefficients in Eq. i.

  18. Response of topside ionosphere to man-made electromagnetic emissions

    Investigation of electromagnetic measurements in the VLF range, obtained by DEMETER satellite revealed that terrestrial navigational stations are clearly "visible" in the ionosphere. Statistical studies were performed in the frequency range between 10kHz and 20kHz for one component of electric and magnetic field. We used data collected with ICE and IMSC in-struments placed on-board DEMETER. Global maps of man-made emissions show significant ionospheric response. This first satellite from the CNES MYRIADE micro-satellite series was launched on a polar orbit in June 2004 and provides permanent in-situ observations of ionospheric plasma parameters at the altitude of 700 km. As there are now more than five years of operational data a statistical study on both, the bulk ionospheric parameters and electromagnetic emissions, is possible. Since, statistical analysis have shown how easily are detectable man-made signals in the ionosphere, it has implied further studies on other plasma parameters. Using Langmuir probe experiment ISL ("Instrument Sonde de Langmuir") we develop global maps for electron temperature and density. Data are represented in geographic coordinates and averaged over one-month period. We present comparison analysis, that give the statistical background for further studies of noises occurring in the upper layers of ionosphere.

    1980-09-01

    A 51-year-old man was admitted for evaluation and treatment of scrotal pain of 20 years' duration following unilateral orchiectomy for right testicular injury. Past attempts had failed to provide definitive or persistent relief. Physical examination and investigations were unremarkable. Psychiatric assessment revealed an angry, depressed man with a drasmatic, hypermasculine manner and hysterical and obsessive personality traits. Review of systems with a structured interview indicated that the patient had numerous medically unexplained symptoms and that he fulfilled both the Feighner and the Diagnostic and Statistical Manual of Mental Disorders 3rd edition (DSM-III) diagnostic criteria for Briquet syndrome. The case is important because it demonstrates the usefulness of recognizing Briquet syndrome in patients with the single presenting complaint of chronic, intractable pain, and the fact that Briquet syndrome, commonly considered a female disorder, can occur in men regardless of sexual orientation and in the absence of expected compensation. In addition, the case confirms the utility of a structured interview and defined criteria for making the diagnosis of Briquet syndrome.

  20. Solar particle event predictions for manned Mars missions

    NASA Technical Reports Server (NTRS)

    1986-01-01

    Manned space missions to Mars require consideration of the effects of high radiation doses produced by solar particle events (SPE). Without some provision for protection, the radiation doses from such events can exceed standards for maximum exposure and may be life threatening. Several alternative ways of providing protection require a capability for predicting SPE in time to take some protective actions. The SPE may occur at any time during the eleven year solar cycle so that two year missions cannot be scheduled to insure avoiding them although they are less likely to occur at solar minimum. The present forecasts are sufficiently accurate to use for setting alert modes but are not accurate enough to make yes/no decisions that have major mission operational impacts. Forecasts made for one to two year periods can only be done as probabilistic forecasts where there is a chance of SPE occurring. These are current capabilities but are not likely to change significantly by the year 2000 with the exception of some improvement in the one to ten day forecasts. The effects of SPE are concentrated in solar longitudes near where their parent solar flares occur, which will require a manned Mars mission to carry its own small solar telescope to monitor the development of potentially dangerous solar activity. The preferred telescope complement includes a solar X-ray imager, a hydrogen-alpha scanner, and a solar magnetograph.

    2004-01-01

    New surgical procedures, novel concepts, and/or the presentation of very good results with an apparently discredited technique meet varying degrees of resistance among the establishment of any profession. In hand surgery this phenomenon was exemplified in a striking fashion with the presentation of a controversial report entitled, "Primary repair of flexor tendons in no man's land" by Kleinert, Kutz, Ashbell, and Martinez of Louisville, KY, at the 1967 American Society for Surgery of the Hand (ASSH) annual meeting. The discussant, Joseph Boyes, expressed such skepticism that a special ASSH committee was appointed to go to Louisville and review the results to determine if they were as good as claimed. They were, and today primary flexor tendon repair is the procedure of choice for most flexor tendon lacerations.

    Using whole-exome sequencing, we identified homozygous mutations in two unlinked genes, SEC23A c.1200G>C (p.M400I) and MAN1B1 c.1000C>T (p.R334C), associated with congenital birth defects in two patients from a consanguineous family. Patients presented with carbohydrate-deficient transferrin, tall stature, obesity, macrocephaly, and maloccluded teeth. The parents were healthy heterozygous carriers for both mutations and an unaffected sibling with tall stature carried the heterozygous mutation in SEC23A only. Mutations in SEC23A are responsible for craniolenticosultura dysplasia (CLSD). CLSD patients are short, have late-closing fontanels, and have reduced procollagen (pro-COL1A1) secretion because of abnormal pro-COL1A1 retention in the endoplasmic reticulum (ER). The mutation we identified in MAN1B1 was previously associated with reduced MAN1B1 protein and congenital disorders of glycosylation (CDG). CDG patients are also short, are obese, and have abnormal glycan remodeling. Molecular analysis of fibroblasts from the family revealed normal levels of SEC23A in all cells and reduced levels of MAN1B1 in cells with heterozygous or homozygous mutations in SEC23A and MAN1B1. Secretion of pro-COL1A1 was increased in fibroblasts from the siblings and patients, and pro-COL1A1 was retained in Golgi of heterozygous and homozygous mutant cells, although intracellular pro-COL1A1 was increased in patient fibroblasts only. We postulate that increased pro-COL1A1 secretion is responsible for tall stature in these patients and an unaffected sibling, and not previously discovered in patients with mutations in either SEC23A or MAN1B1. The patients in this study share biochemical and cellular characteristics consistent with mutations in MAN1B1 and SEC23A, indicating a digenic disease. PMID:27148587

    2011-03-01

    A 58-year-old man presented to the hospital with fever and headache after amoxicillin intake. Physical examination, laboratory, and a cranial CT scan were unremarkable. Cerebrospinal fluid (CSF) testing revealed lymphocytic pleocytosis. After discontinuation of amoxicillin and symptomatic care, the patient quickly improved. Interestingly, he had had two prior episodes of aseptic meningitis that were probably also related to the administration of amoxicillin. Aseptic meningitis can be caused by multiple non-infectious conditions including drugs, malignancy, and autoimmune diseases. We report a case associated with amoxicillin that meets the criteria of drug-induced aseptic meningitis. Considering the wide utilization of amoxicillin, healthcare providers should be aware of it as a possible cause of drug-induced aseptic meningitis.

    A 58-year-old man was brought to our hospital with left upper abdominal pain which suddenly appeared on the previous evening. An abdominal CT scan showed localized retention of ascites, a slightly high density mass under the left upper abdominal wall, with a high density area detected within the mass, which was suggestive of leakage of contrast medium from peripheral branches of the omental artery. From these findings intraperitoneal hemorrhage caused by bleeding from the greater omentum was suspected. Angiographic examination of the abdomen indicated extravasation of contrast medium from blood vessels of the right gastroepiploic artery. Transarterial embolization was carried out and permanent hemostasis was achieved. Injury, anticoagulant, neoplasms, varix, torsion of the omentum, and segmental arterial mediolysis (SAM) etc have been reported as causes of omental bleeding, but none of these were found in our case. We diagnosed the present case as idiopathic omental bleeding.

    While neck of femur fractures are common it is rare to see this injury in a bilateral leg amputee. Special consideration needs to be given to the management of these patients. We report the case of a 58-year-old man with bilateral leg amputation who presented to the emergency department with left hip pain following a fall. A fracture of the left neck of femur with extension into the femoral shaft was diagnosed. Internal fixation was planned with a dynamic hip screw. Standard fracture table setup, which allows for traction of the fractured limb and positioning of the contralateral limb such that anteroposterior and lateral X-rays can be obtained, was not possible in this case due to the amputations. We highlight considerations that need to be made in positioning a bilateral amputee for neck of femur fracture fixation and also highlight an improvised technique that can be utilised by other surgeons.

    Scrotal elephantiasis is a pathology of often unknown etiology. Symptomatology is characterized by an oedematius infiltration of skin and subcutaneous tissue, hard-bound aspect and purplished color. The scrotum, the penis and the perineal area are gradually affected. This pathology is very invalidating for the patient, on functional, sexual and aesthetic aspects. The authors present the case of a 58-year-old man with an enormous scrotal mass invading the penis and drowning the testicular elements, which were impossible to palpate. The aetiology was determined by exclusion and an iatrogenic origin following the cure of bilateral inguinal hernia was retained. Resection of the scrotal mass was performed. The reconstruction of the scrotal purse and the cutaneous sleeve of the penis were carried out using local flaps of the remaining healthy skin.

    A 58-year-old man was admitted to our hospital. Laboratory data showed severe liver injury and that the patient was positive for immunoglobulin M anti-hepatitis A virus (HAV) antibodies. He was also complicated with severe renal dysfunction and had an extremely high level of serum hepatocyte growth factor (HGF). Therefore, he was diagnosed with severe acute liver failure with acute renal failure (ARF) caused by HAV infection. Prognosis was expected to be poor because of complications by ARF and high serum HGF. However, liver and renal functions both improved rapidly without intensive treatment, and he was subsequently discharged from our hospital on the 21(st) hospital day. Although complication with ARF and high levels of serum HGF are both important factors predicting poor prognosis in acute liver failure patients, the present case achieved a favorable outcome. Endogenous HGF might play an important role as a regenerative effector in injured livers and kidneys.

    Sjögren's syndrome (SS) is a systemic autoimmune disease that mainly affects the exocrine glands. It has been reported that the association between SS and respiratory involvement occurs in 11% and 45% of cases, and can be the initial manifestation of the disease. The diagnosis is based on the integration of clinical, immunological and histopathological criteria. This paper examines a 58-year-old man with SS, severe dyspnea and recurrent exacerbations associated with bronchiolitis-bronchiectasis. The absence of anti-Ro and anti-La antibodies associated with severe bronchiolitis is a clinical presentation that is poorly characterized in this group of patients; moreover, how to treat them remains unclear.

    A 58-year-old man presented to our hospital with effort angina. Ten months prior, he was treated with a Bioresorbable vascular scaffold (BVS). During the current admission, an image angiographically compatible with in-BVS restenosis at the circumflex ostium with a radiolucent image in the ostial left anterior descending artery was shown. BVS failure is very infrequent and this is one of the first cases of BVS restenosis described. Thus, data on the best management option are scarce. We treated it like a drug-eluting stent restenosis, performing first an intracoronary optical coherence tomography scan in order to identify the left descending radiolucent image and to prepare the best treatment strategy.

  11. Postural Control in Man: The Phylogenetic Perspective

    PubMed Central

    Gramsbergen, Albert

    2005-01-01

    Erect posture in man is a recent affordance from an evolutionary perspective. About eight million years ago, the stock from which modern humans derived split off from the ape family, and from around sixty-thousand years ago, modern man developed. Upright gait and manipulations while standing pose intricate cybernetic problems for postural control. The trunk, having an older evolutionary history than the extremities, is innervated by medially descending motor systems and extremity muscles by the more recent, laterally descending systems. Movements obviously require concerted actions from both systems. Research in rats has demonstrated the interdependencies between postural control and the development of fluent walking. Only 15 days after birth, adult-like fluent locomotion emerges and is critically dependent upon postural development. Vesttibular deprivation induces a retardation in postural development and, consequently, a retarded development of adult-like locomotion. The cerebellum obviously has an important role in mutual adjustments in postural control and extremity movements, or, in coupling the phyiogenetic older and newer structures. In the human, the cerebellum develops partly after birth and therefore is vulnerable to adverse perinatal influences. Such vulnerability seems to justify focusing our scientific research efforts onto the development of this structure. PMID:16097476

    1992-01-01

    GridMan is an interactive grid manipulation system. It operates on grids to produce new grids which conform to user demands. The input grids are not constrained to come from any particular source. They may be generated by algebraic methods, elliptic methods, hyperbolic methods, parabolic methods, or some combination of methods. The methods are included in the various available structured grid generation codes. These codes perform the basic assembly function for the various elements of the initial grid. For block structured grids, the assembly can be quite complex due to a large number of clock corners, edges, and faces for which various connections and orientations must be properly identified. The grid generation codes are distinguished among themselves by their balance between interactive and automatic actions and by their modest variations in control. The basic form of GridMan provides a much more substantial level of grid control and will take its input from any of the structured grid generation codes. The communication link to the outside codes is a data file which contains the grid or section of grid.

    Fourteen monogenic cutaneous disorders of man are compared to similar gene defects in animals. The traits are classified into two groups. In the first group, an identity (homology) of the underlying gene defects is likely. This group includes oculo-cutaneous albinism, Chédiak-Higashi syndrome, aplasia cutis congenita, Ehlers-Danlos syndrome (type I), hypohidrotic ectodermal dysplasia of the Christ-Siemens-Touraine type, X-linked dominant chondrodysplasia punctata, ichthyosis congenita gravis, Menkes syndrome, erythropoetic porphyria, porphyria cutanea tarda, and acrodermatitis enteropathica. In the second group, the traits are similar but the question of their homology cannot be settled. It includes alopecia congenita, hidrotic ectodermal dysplasia of the Clouston type, and hereditary lymphedema. The existence of identical mutations in man and animals provides evidence for the close relationship between the various mammalian species. Homologous traits affecting the skin are of practical importance since the use of these animal models may help to answer those questions which cannot be answered by performing research in human patients.

  14. Integrated shielding systems for manned interplanetary spaceflight

    1992-01-01

    The radiation environment encountered by manned interplanetary missions can have a severe impact on both vehicle design and mission performance. This study investigates the potential impact of radiation protection on interplanetary vehicle design for a manned Mars mission. A systems approach was used to investigate the radiation protection requirements of the sum interplanetary environment. Radiation budgets were developed which result in minimum integrated shielding system masses for both nuclear and non-nuclear powered missions. A variety of system configurations and geometries were assessed over a range of dose constraints. For an annual dose equivalent rate limit of 50 rem/yr, an environmental shielding system composed of a habitat shield and storm shelter was found to result in the lowest total mass. For a limit of 65 rem/yr, a system composed of a sleeping quarters shield was least massive, and resulted in significantly reduced system mass. At a limit of 75 rem/yr, a storm shelter alone was found to be sufficient, and exhibited a further mass reduction. Optimal shielding system results for 10 MWe nuclear powered missions were found to follow along similar lines, with the addition of a reactor shadow shield. A solar minimum galactic cosmic ray spectrum and one anomalously large solar particle event during the course of a two year mission were assumed. Water was assumed for environmental radiation shielding.

  16. Fixing the skin barrier: past, present and future--man and dog compared.

    PubMed

    Marsella, Rosanna

    2013-02-01

    Skin barrier dysfunction exists in both human and canine atopic dermatitis, leading to increased water loss and potentially facilitating allergen penetration and sensitization. Both lipid (e.g. ceramides) and protein (e.g. filaggrin) abnormalities have been described. Some are genetically inherited (e.g. filaggrin mutations are one of the major risk factors in humans) and some are secondary and linked to inflammation. In humans, numerous studies have shown efficacy of emollients and moisturizers in barrier restoration, and this approach has been for years the mainstay of therapy. Recently, this strategy has shown promise as a preventative function. In veterinary medicine, evidence regarding skin barrier impairment is rapidly building. Decreased ceramides and filaggrin (in some subsets of dogs) have been described. Altered metabolism of ceramides has also been proposed. Despite these preliminary data and the availability of products marketed to improve the skin barrier, evidence regarding the clinical benefit of skin repair intervention is still limited. Preliminary studies have demonstrated that topical application of fatty acids and ceramides and systemic administration of fatty acids improve lipid deficiencies in the skin of dogs with atopic dermatitis, but limited clinical evidence exists. Disease remission in humans is paralleled by an improved skin barrier, both with calcineurin inhibitors and glucocorticoids. In veterinary medicine, a preliminary study on ciclosporin and prednisone failed to detect significant improvement of water loss, while successful immunotherapy correlated with an improved skin barrier. Controlled, large studies are needed to address the question of which skin repair approach is clinically most effective and whether this can be used as a preventative strategy.

    1989-01-01

    As the 21st century approaches, there is an ever-increasing interest in launching manned missions to Mars. A major concern to mission planners is exposure of the flight crews to highly penetrating and damaging space radiations. Beyond the protective covering of the Earth's magnetosphere, the two main sources of these radiations are galactic cosmic rays and solar particle events. Preliminary analyses of potential exposures from galactic cosmic rays (GCR's) were presented elsewhere. In this Note, estimates of shielding thicknesses required to protect astronauts on interplanetary missions from the effects of large solar flare events are presented. The calculations use integral proton fluences for the February 1956, November 1960, and August 1972 solar particle events as inputs into the NASA Langley Research Center nucleon transport code BRYNTRN. This deterministic computer code transports primary protons and secondary protons and neutrons through any number of layers of target material of arbitrary thickness and composition. Contributions from target nucleus breakup (fragmentation) and recoil are also included. The results for each flare are presented as estimates of dose equivalent [in units of roentgen equivalent man (rem)] to the skin, eye, and bloodforming organs (BFO) behind various thicknesses of aluminum shielding. These results indicate that the February 1956 event was the most penetrating; however, the August 1972 event, the largest ever recorded, could have been mission- or life-threatening for thinly shielded (< or = 5 g/cm2) spacecraft. Also presented are estimates of the thicknesses of water shielding required to reduce the BFO dose equivalent to currently recommended astronaut exposure limits. These latter results suggest that organic polymers, similar to water, appear to be a much more desirable shielding material than aluminum.

    We hereby present the case of a 25-year-old man who presented at the emergency department of Civil Hospital Karachi, Pakistan with signs and symptoms of acute viral hepatitis. Serology tests revealed that the patient was suffering from hepatitis E viral (HEV) infection. Concurrently, the patient was also found to have thrombocytopaenia (TCP). His TCP became better after the resolution of his jaundice, with the patient requiring a transfusion of one mega unit of platelets. After ruling out other common causes of TCP and after a thorough literature search, we concluded that an immune-mediated mechanism secondary to HEV infection might have been the cause behind his low platelet counts. Hence, we propose considering the possibility of HEV infection in patients presenting with acute liver failure and TCP, irrespective of age, gender, and geographical location of the patient.

    This article reports a case of colovesical fistula presenting with epididymitis. A 75-year-old man with a recent conservatively managed localised diverticular perforation presented to hospital with acute pain and swelling of his left testicle and epididymis. On further questioning, the patient reported passing air in his urine. Urine cultures grew Enterococcus faecalis. Ultrasound scan confirmed a diagnosis of bacterial epididymitis and the patient was treated with intravenous antibiotics. Subsequent CT imaging revealed air in the bladder and a colovesical fistula. The patient went on to have Hartmann's procedure with repair of the bladder defect. This case highlights that: (1) Colovesical fistulae may rarely present with epididymitis. (2) Colovesical fistulae are the most common cause of pneumaturia.

A dynamic evaluation tool is presented to provide for a determination of the effectiveness of the man-machine interface in terms of the sequence of operations (task and task sequences) and in terms of the physical characteristics of the interface. This dynamic checklist approach is recommended for shuttle and shuttle payload man-machine interface evaluations based on reduced preparation time, reduced data, and increased sensitivity of critical problems.

  4. Methods of space radiation dose analysis with applications to manned space systems

    NASA Technical Reports Server (NTRS)

    Langley, R. W.; Billings, M. P.

    1972-01-01

    The full potential of state-of-the-art space radiation dose analysis for manned missions has not been exploited. Point doses have been overemphasized, and the critical dose to the bone marrow has been only crudely approximated, despite the existence of detailed man models and computer codes for dose integration in complex geometries. The method presented makes it practical to account for the geometrical detail of the astronaut as well as the vehicle. Discussed are the major assumptions involved and the concept of applying the results of detailed proton dose analysis to the real-time interpretation of on-board dosimetric measurements.

  5. Fibroadenoma of the breast in a man associated with adenocarcinoma of the rectum and polyposis coli.

    2010-01-01

    Fibroadenoma of the breast is an uncommon cause of breast lumps in men. Only a few cases have been reported in the literature, the majority of which were prescribed estrogen. We present herein the first case of a fibroadenoma of the breast in a 68-year-old man with adenocarcinoma of the rectum and polyposis coli. In this case, there was neither estrogen treatment nor any other medications which have been discussed in the literature as inducing fibroadenomas. Fibroadenomas in men without hormone treatment and with normal hormone levels are extremely rare and the developmental mechanism of the breast fibroadenoma in this man is under question.

  6. Manned orbital systems concept study. Book 4: Programmatics for extended-duration missions

    NASA Technical Reports Server (NTRS)

    1975-01-01

    The cost estimates, schedule data, and funding distributions generated in the Manned Orbital Systems Concepts (MOSC) study are presented. The overall objectives were to examine the requirements for, and to describe, a cost-effective concept for an orbital facility capable of supporting manned operations in earth orbit beyond the 7-to-30-day mission duration provided by the Shuttle/Spacelab system. The cost, schedule, and other programmatic data were developed to provide information useful for their long-range planning activities. The major portion of the data documented and discussed consists of project- and system-level schedule and funding information and also project-, system-, and subsystem-level cost summaries.

  7. From the APOLLO legacy to Mars, what can the manned exploration programme bring to planetary science?

    NASA Astrophysics Data System (ADS)

    Muller, C.

    Manned space began with the promise of setting foot on the Moon in the first decade of the space age; this was done by the APOLLO project which combined unprecedented technological innovation with space and moon science. The scientific results of APPOLO will be briefly reviewed together with the lessons to be learnt from this unique experience. In the last 34 years, manned space was limited to low earth orbit and it can be reasonably argued that the science return from continuing will be to the maximum incremental, however, the full use of the present space station could still be considered for external instrument platforms as, for example, a planetary telescope. Independently of the science objectives, the Presidential Vision in the United States and the Lisbon declaration of the European Union have led to new manned exploration programmmes returning to the Moon, going to Mars and beyond. The current status of these ambitious projects and their return for planetary science will be reviewed.

  8. Modelling radiation fluxes in simple and complex environments: basics of the RayMan model.

    PubMed

    Matzarakis, Andreas; Rutz, Frank; Mayer, Helmut

    2010-03-01

    Short- and long-wave radiation flux densities absorbed by people have a significant influence on their energy balance. The heat effect of the absorbed radiation flux densities is parameterised by the mean radiant temperature. This paper presents the physical basis of the RayMan model, which simulates the short- and long-wave radiation flux densities from the three-dimensional surroundings in simple and complex environments. RayMan has the character of a freely available radiation and human-bioclimate model. The aim of the RayMan model is to calculate radiation flux densities, sunshine duration, shadow spaces and thermo-physiologically relevant assessment indices using only a limited number of meteorological and other input data. A comparison between measured and simulated values for global radiation and mean radiant temperature shows that the simulated data closely resemble measured data.

    Sir Frederick Treves first showed Joseph Merrick, the famous Elephant Man, to the Pathological Society of London in 1884. A diagnosis of neurofibromatosis was suggested in 1909 and was widely accepted. There is no evidence, however, of café au lait spots or histological proof of neurofibromas. It is also clear that Joseph Merrick's manifestations were much more bizarre than those commonly seen in neurofibromatosis. Evidence indicates that Merrick suffered from the Proteus syndrome and had the following features compatible with this diagnosis: macrocephaly; hyperostosis of the skull; hypertrophy of long bones; and thickened skin and subcutaneous tissues, particularly of the hands and feet, including plantar hyperplasia, lipomas, and other unspecified subcutaneous masses.

  8. Urinary Excretion of Antidiuretic Hormone in Man

    NASA Technical Reports Server (NTRS)

    Miller, M.

    1972-01-01

    It is shown that urinary excretion of ADH can be detected readily and quantitated accurately. The ADH excretion in normal subjects is inhibited following the administration of a water load and stimulated following water deprivation. It appears that measurement of ADH excretion in man provides a means of quantitating alterations in neurohypophyseal ADH secretion. By determining not only the basal excretion of ADH but also the response to such physiological influences as water loading and dehydration, it becomes possible to study the dynamics of ADH release. Thus, the ability to extract ADH efficiently from urine combined with a sensitive and specific technique for determination of ADH concentration allows the exploration of regulatory systems for ADH control in the normal state as well as the etiological role of altered ADH secretion in clinical disorders of water balance.

    2013-01-01

    Using two books by Adolphe Quetelet, I analyze his theory of the 'average man', which associates biological and social normality with the frequency with which certain characteristics appear in a population. The books are Sur l'homme et le développement de ses facultés and Du systeme social et des lois qui le régissent. Both reveal that Quetelet's ideas are permeated by explanatory strategies drawn from physics and astronomy, and also by discursive strategies drawn from theology and religion. The stability of the mean as opposed to the dispersion of individual characteristics and events provided the basis for the use of statistics in social sciences and medicine.

    Danon disease is a rare, codominant X-linked genetic disorder characterized by the triad of left ventricular hypertrophy, mental retardation, and peripheral myopathy. This disease is caused by mutations in the gene that encodes lysosomal associated membrane protein 2 (LAMP2), a deficiency of which results in the accumulation of autophagic granular débris within the vacuoles of muscle cells. This is a report of an asymptomatic 19-year-old man with Danon disease in the absence of mental retardation or clinically significant skeletal myopathy. This case underscores the importance of accurate diagnosis of unexplained left ventricular hypertrophy, in order to establish an appropriate treatment plan and to advise genetic counseling.

  12. Manned remote work station development article

    NASA Technical Reports Server (NTRS)

    1978-01-01

    The two prime objectives of the Manned Remote Work Station (MRWS) Development Article Study are to first, evaluate the MRWS flight article roles and associated design concepts for fundamental requirements and embody key technology developments into a simulation program; and to provide detail manufacturing drawings and schedules for a simulator development test article. An approach is outlined which establishes flight article requirements based on past studies of Solar Power Satellite, orbital construction support equipments, construction bases and near term shuttle operations. Simulation objectives are established for those technology issues that can best be addressed on a simulator. Concepts for full-scale and sub-scale simulators are then studied to establish an overall approach to studying MRWS requirements. Emphasis then shifts to design and specification of a full-scale development test article.

  13. Earth orbital operations supporting manned interplanetary missions

    NASA Technical Reports Server (NTRS)

    Sherwood, Brent; Buddington, Patricia A.; Whittaker, William L.

    1989-01-01

    The orbital operations required to accumulate, assemble, test, verify, maintain, and launch complex manned space systems on interplanetary missions from earth orbit are as vital as the flight hardware itself. Vast numbers of orbital crew are neither necessary nor desirable for accomplishing the required tasks. A suite of robotic techniques under human supervisory control, relying on sensors, software and manipulators either currently emergent or already applied in terrestrial settings, can make the job tractable. The mission vehicle becomes largely self-assembling, using its own rigid aerobrake as a work platform. The Space Station, having been used as a laboratory testbed and to house an assembly crew of four, is not dominated by the process. A feasible development schedule, if begun soon, could emplace orbital support technologies for exploration missions in time for a 2004 first interplanetary launch.

    Drawing upon worldwide examples, the author traces mankind's interaction with nature and examines human interference with environmental systems at various stages of social development. Succeeding chapters take up man's specific impact on vegetation, animals, the soil, the waters, landforms, climate, and the atmosphere. With the aid of maps, diagrams, and graphs, the book analyzes the causes and consequences of environmental changes associated with such large-scale events as agricultural expansion, domestication, deforestation, and urbanization, including the spread of salination, extinction, erosion, and pollution. Interrelations, often dynamic and unpredictable, between these phenomena make it difficult to isolate the causes of changes and to determine the resiliency of natural systems to change. 505 references, 82 figures, 97 tables.

    1981-01-01

    From a study that identified over 100 possible geosynchronous orbit-related applications for manned orbit transfer vehicles (MOTV), a group of 20 are chosen for consideration. These generic missions can be grouped into five categories: (1) inspection service and repair, (2) operation of large systems, (3) debris removal, (4) construction, and (5) unmanned cargo. Among the findings of this study is that space basing permits more efficient use of Space Shuttle flights, since the core propulsion system, crew cabin and general purpose mission hardware need not be launched into space each time. A conservative traffic model shows that $600 million may be saved over five years by space basing, due to the decreased number of Shuttle flights needed to support the space-based MOTV. Crew information, payloads, characteristics of the vehicle, and mission requirements are covered in detail.

The concept elements include a Mach 3 staging unmanned glideback booster and a 149-ft long winged orbiter with an external payload canister with a 15-ft diameter and 30-ft long payload bay. The booster and orbiter main propulsion system is a lightweight derivative of the current Space Shuttle Main Engine. The primary mission is the Space Station Freedom logistics mission, 40,000-lb payload with two crew members and eight passengers. The structural design and material selection, the thermal protection system, the integral cryogenic tanks and insulation, the propulsion system, and the modular payload canister system are described. The ground and flight operations approach analysis, the manufacturing and certification plan, and the technology development requirements are also discussed.

  18. Preconception selection of sex in man.

    PubMed

    Stolkowski, J; Choukroun, J

    1981-11-01

    The determination of sex is influenced by ionic factors. In man, ionic imbalance is responsible for the sex ratio in at least 80% of cases, the possible mechanism being one of selective fertilization. These facts constitute the scientific basis for the medicodietary method of selecting sex. The intervention of ions in ovarian metabolism is obtained by controlling the diet of the woman, the decisive factor being the ratio of K+ + Na+ to Ca2+ + Mg2+ in the daily diet. High values of this ratio lead to boys, and low values to girls. Using this method since 1970 in 47 births, only 7 of them failed to produce the expected sex. The interactions and the causes of failure are analyzed.

    1995-06-01

    Classical mechanics is based upon a mechanical picture of nature that is fundamentally incorrect. It has been replaced at the basic level by a radically different theory: quantum mechanics. This change entails an enormous shift in one`s basic conception of nature, one that can profoundly alter the scientific image of man himself. Self-image is the foundation of values, and the replacement of the mechanistic self-image derived from classical mechanics by one concordant with quantum mechanics may provide the foundation of a moral order better suited to today`s times, a self-image that endows human life with meaning, responsibility, and a deeper linkage to nature as a whole.

  20. Boscovich: scientist and man of letters

    NASA Astrophysics Data System (ADS)

    Proverbio, E.

    Ruggiero Giuseppe Boscovich (1711-1781) is known as one of the most important scientists of the second half of XVIII century, but he was active also as a man of letters, especially through an abundant production of poems in Latin verse. We try to interpret these two, apparently antinomic, aspects of his character in the framework of the culture of his epoch, in which science and literary productions were not considered as two separate or opposite fields, but only two different aspects of human knowledge. In particular we review the field of his poetic production in which this fundamental unity of knowledge is most evident, namely his poems with didactic-scientific subjects, which are examples of high-level popularization of the latest progresses in science (in particular astronomy and Newtonian physics) by means of elegant Latin verse.

  1. [Hemoptysis in a young man smoking cannabis].

    PubMed

    Monfort, M; Larakeb, A; Gouraud, F

    2013-06-01

    The respiratory toxicity of cannabis is well known today. Along with the classic cannabis 'joint', there are other ways of consuming it, which should be known. Smoking cannabis that has been cut with micro-particles of silicon dioxide may cause hemoptysis. We will describe here the case of a young 16-year-old man who was in the hospital because of hemoptic expectoration. The etiologic investigation was negative, in particular a thoracic scan and a bronchial fiberscope. Questioning the patient afterwards allowed us to discover the inhalation of cannabis 2 h before the hemoptysis, cannabis mixed with micro-particles of silicon dioxide. Stopping inhalation stopped the symptoms. Pediatricians should be familiarized with such practices. Silicon dioxide particles cause ENT problems or bronchial ones (coughing, spitting, hemoptysis, wheezing). Over the long term, the risk of silicosis cannot be excluded, although a longer and more complete exposure is necessary.

    1974-01-01

    A four-state random stimulus generator, considered to function as an ESP teaching machine was used to investigate an approach to facilitating interactions between man and machines. A subject tries to guess in which of four states the machine is. The machine offers the user feedback and reinforcement as to the correctness of his choice. Using this machine, 148 volunteer subjects were screened under various protocols. Several whose learning slope and/or mean score departed significantly from chance expectation were identified. Direct physiological evidence of perception of remote stimuli not presented to any known sense of the percipient using electroencephalographic (EEG) output when a light was flashed in a distant room was also studied.

    We describe the case of a 62-year-old man who presented with shortness of breath that had progressed over several years. He had a history of a paralyzed right hemidiaphragm for at least the previous 10 years. He also reported weakness in his proximal legs and daytime sleepiness. On examination, he was found to have thoracoabdominal paradox when in supine position. Pulmonary function testing revealed severe restriction; arterial blood gas showed chronic respiratory acidosis. Electromyography showed chronic phrenic neuropathy bilaterally, with mild proximal myopathy. Serum aldolase level was mildly elevated, but serologic tests for connective tissue disorders were within reference range. After extensive clinical investigations, the patient was found to have severely reduced acid α-glucosidase. Genetic analysis confirmed the diagnosis of adult-onset Pompe disease. The patient started treatment with bilevel positive airway pressure titrated during polysomnography, and acid α-glucosidase enzyme replacement was recommended. PMID:27141434

    Exposure to thermal environment is one of the main concerns for manned space exploration. By focusing on the works performed on thermoregulation at microgravity or simulated microgravity, we endeavored to review the investigation on space thermal environmental physiology. First of all, the application of medical requirements for the crew module design from normal thermal comfort to accidental thermal emergencies in a space craft will be addressed. Then, alterations in the autonomic and behavioral temperature regulation caused by the effect of weightlessness both in space flight and its simulation on the ground are also discussed. Furthermore, countermeasures like exercise training, simulated natural ventilation, encouraged drink, etc., in the protection of thermoregulation during space flight is presented. Finally, the challenge of space thermal environment physiology faced in the future is figured out.

  5. [An aphasic man with high fever; difficulty with diagnostic procedure].

    A 73-year-old man, with known motor aphasia presented with high fever, dyspnoea, and vomiting. Only after several days it appeared that these signs were due to a sepsis as a consequence of a phlegmon of the neck, caused by an aspired part of his set of false teeth. The delay before diagnosis was due to the fact that adequate medical history taking was difficult because of the aphasia and attempts at non-verbal communication were poorly understood. The localization of the corpus alienum was a second pitfall, because it could not be visualized during physical examination or on the initial chest X-ray. The increased risk of colonization of dentures with pathogenic micro-organisms in nursing home residents may have played a role in the severe course of this infection. This case illustrates the diagnostic problems that may exist in patients who are unable to communicate adequately.

    Metastasis of an extracranial malignant neoplasm to a meningioma is a rare event.We report a case of a 72-year-old man who presented abruptly with a grand mal seizure. Neuroradiological examination revealed an extraaxial lesion located in the posterior right frontal convexity with poorly defined boundaries. Histological and immunohistochemical examination showed that the lesion was a meningothelial meningioma harboring metastatic renal cell carcinoma.The MRI could be indicative but not specific of this type of lesion.Some cases of intracranial meningiomas containing metastatic carcinomas have been published, but to our knowledge only five cases of renal cell carcinoma metastasizing to a meningioma have been reported. Possible explanations for this type of "tumor in tumor" lesion are reviewed.

    Radiation measurements obtained on board U.S. and Soviet spacecraft are presented and discussed. A considerable amount of data has now been collected and analyzed from measurements with a variety of detector types in low-Earth orbit. The objectives of these measurements have been to investigate the dose and Linear Energy Transfer (LET) spectra within the complex shielding of large spacecraft. The shielding modifies the external radiation (trapped protons, electrons, cosmic ray nuclei) which, in turn, is quite dependent on orbital parameters (altitude, inclination). For manned flights, these measurements provide a crew exposure record and a data base for future spacecraft design and flight planning. For the scientific community they provide useful information for planning and analyzing data from experiments with high sensitivity to radiation. In this paper, results of measurements by both passive and active detectors are described. High-LET spectra measurements were obtained by means of plastic nuclear track detectors (PNTD's) while thermoluminescent dosimeters (TLD's) measured the dose.

    Dermatophilus congolensis infection (dermatophilosis) is an acute, subacute or chronic skin disease affecting a wide range of species of animals and man. It is world widely distributed but more prevalent in the humid, tropics and subtropics. The disease is now being reviewed in detail. In the present review, the geographical distribution, history and nomenclature, animal hosts affected, aetiological agent and clinical signs of the disease are discussed extensively. Emphasis is also given on the predisposing factors such as rainfall, humidity, ectoparasites etc. under epizootiology. Pathogenesis, pathology, immunology treatment, control and prophylaxis are other areas well covered. The economic importance of the disease is also stressed and a new approach (biological approach) to treatment and control of the disease is being described in this review. It was concluded that in view of the importance of the disease for the increase of livestock and leather production in the tropical and subtropical region especially in Africa, an international centre for dermatophilosis research is highly needed.

    The purpose of this paper is to present the engineering design of the advanced Man-Machine Interface (MMI) of the Integrated system for Radwaste Treatment and Storage (RTS) facility in Institute of Nuclear Energy Research (INER) Taiwan, ROC. To build the RTS, a multi-function radwaste facility with a total storage of about 10,000 drums, is a five-year project starting in 2000 including intermediate activity waste treatment and combustible waste storage. The completed engineering design of the MMI is based on proven technologies and digital control systems, enhancing the radwaste management efficiency and reliability of operator's performance as well as assuring the dose exposure of personnel meeting the regulation standard. Over past few years, INER has accumulated extensive experience in the area of radwaste treatment and storage. Therefore, we are confident that we will complete this project with fulfillment of the requirements of RTS.

  11. Proprietary Manned Space Flight Proposals, 1973 to 2013, plus

    In 1973 a concept for a manned space flight experiment was submitted to NASA as an unsolicited proprietary proposal,*. In 1998*, 2004*, and 2013* proposals successively more details were provided. An abbreviation of the 1998 proposal was published. By 2013 the five technical variables of 1998 had increased to over ten. Some technical and management details of the proposals will be presented and updated. The first flight of two could use some hardware now being developed. The experiment seems superior to any mission publicly advocated by NASA, so this talk's purpose is to encourage NASA to delay landing humans on Mars until the first spacecraft can be developed and activated. *Complete proposals are in the Philip C. Fisher papers, Niels Bohr Library and Archives, American Institute of Physics (available one year after author's death). Work after 1982 supported by successive forms of Ruffner Associates.

    A trajectory optimization method of the nuclear propulsion manned asteroids exploration is presented. In the case of launching between 2035 and 2065, based on the Lambert transfer orbit, the phases of departure from and return to the Earth are searched at first. Then the optimal flight trajectory in the feasible regions is selected by pruning the flight sequences. Setting the nuclear propulsion flight plan as propel-coast-propel, and taking the minimal mass of aircraft departure as the index, the nuclear propulsion flight trajectory is separately optimized using a hybrid method. With the initial value of the optimized local parameters of each three phases, the global parameters are jointedly optimized. At last, the minimal departure mass trajectory design result is given.

  13. Intracranial metallic foreign bodies in a man with a headache

    We report the case of a 22-year old man with intracranial metallic foreign bodies who presented complaining of a headache. His history of headaches had begun when he was five years old and continued with increasing severity. Six months before hospital admission, nausea and vomiting began to accompany his headache. Computed tomography scan revealed that 2 metallic foreign bodies were located adjacent to the vertex and another was next to the ambient cistern. The location and position of foreign bodies suggested that they were introduced in infancy through the anterior fontanelle before its closure in an unsuccessful homicide attempt. This case is one of the few reported cases combining headache and intracranial foreign bodies and we discuss the relationship between headache and these metallic materials. PMID:23355931

  14. Considerations for policy on man-made debris propagation control

    NASA Technical Reports Server (NTRS)

    Fielder, D.

    1985-01-01

    The present rates of man-made, space object propagation are such that there is a real probability of self propagation which, if uncontrolled can lead to a serious limitation to future uses of spacecraft for beneficial purposes. Effective control over the debris issue requires adoption and adherence to policy at a world wide level (any one nation's unknowing, selfish or deliberately adverse action can conceivably jeopardize other useful applications of space satellites for years into the future). The near-term environment may not seriously jeopardize the near-term missions. However, absence of control and/or nonadherence to a control policy in the near-term can result in a debris environment that can severely limit long - term mission opportunities. The data upon which these observations are based continues to be investigated. These investigations tend to validate the preceding observations and emphasize the need for near-term action to establish responsible control policy and implementation actions.
