Published: July 2015

<p class="Default">In this study, an effective and time-saving strategy for groundwater exploration in alluvium basins in arid-semiarid lands was applied by integrating GIS and geophysics. Three steps were followed to locate productive local groundwater aquifers prone to annual recharge in the Region of Petra, which covers an area of 800 km². In the first step, geological, structural and geomorphological knowledge was applied to determine the parts of the sedimentary basin having potentials of being local groundwater aquifers. Some locality of the selected area with suitable hydrological conditions for recharge was chosen for an optimization process using GIS. In the second step, the selected locality of the basin was given emphasize on its detailed geology and hydrology to choose suitable locality for applying gravity visualization. Evaluation of this data leads to step number three. Now at localities with promising conditions vertical electrical soundings was applied to enable the authors to determine productive and renewable groundwater aquifers. As it is known that geophysical methods are considered as expensive and time-consuming work, therefore, in this strategy of groundwater surveying a special attention is given to budgets of time, efforts and funds constraints</p><p class="Default"> </p><p class="Default"><strong>Resumen</strong></p>En este estudio se aplicó una estrategia efectiva y eficaz para la exploración de aguas subterráneas en cuencas con depósitos aluviales para terrenos áridos y semiáridos a través de la integración del Sistema de Información Geográfica (GIS, inglés) y herramientas geofísicas. Se siguieron tres pasos para localizar acuíferos locales de aguas subterráneas propensos a las recargas anuales en la región de Petra, que cubre un área de 800 km2. En el primer paso se aplicó el conocimiento teórico para determinar las partes de la cuenca sedimentaria con el potencial de ser un acuífero local de aguas subterráneas. Se escogió una de las localidades del área seleccionada con condiciones hidrológicas apropiadas de recarga para un proceso de optimización con el GIS. En el segundo paso se hizo énfasis en la geología e hidrología detallada de la localidad seleccionada de la cuenca para así escoger un lugar apropiado para la aplicación del método de visualización gravitacional. La evaluación de los datos condujo el estudio al tercer paso. Se realizaron sondeos eléctricos en los lugares con evidencias para permitirle a los autores determinar los depósitos de aguas subterráneas productivos y renovables. Si bien los métodos geofísicos son considerados costosos y demandantes de tiempo, con esta estrategia de exploración de aguas subterráneas se hizo un énfasis especial a los presupuestos de tiempo, esfuerzo y limitaciones de fondos.
Comportamientos y prejuicios de los jóvenes con relación al VIH/Sida: un estudio cualitativo con jóvenes universitarios nicaragüenses
Authors: Pérez-Pérez Itahisa , Morón-Marchena Juan Agustín , Cobos-Sanchiz David 
Published: July 2015

Objetivos: determinar conocimientos, actitudes y prácticas de riesgo de los jóvenes universitarios nicaragüenses con respecto al VIH para desarrollar propuestas de mejora socio-educativa que permitan contribuir a controlar la pandemia en este contexto. Métodos: se trata de un estudio cualitativo desarrollado en la Facultad Regional Multidisciplinar de Chontales (Universidad Nacional Autónoma de Nicaragua-Managua). Se realizaron dos grupos de discusión con estudiantes, entrevistas a informantes clave del mismo centro, así como un grupo de discusión con expertos de la Comisión Nicaragüense contra el SIDA. Resultados: las expectativas sociales del machismo suponen un obstáculo en materia de educación sexual. Existe una clara diferenciación de género en el discurso explícito sobre el sexo en general y sobre las Infecciones de Transmisión Sexual (ITS) en particular. Se dan diferencias significativas de percepción y conocimientos entre el mundo rural y urbano. Persisten gran cantidad de prejuicios, estereotipos y fobia al contagio. Interpretación y conclusiones: el machismo influye en las relaciones sexuales en cuanto a la utilización de métodos de protección. La cultura tradicional dificulta hablar abiertamente de la sexualidad en las familias y entre iguales. Las prácticas de riesgo no se producen tanto por falta de información como sí por la escasa concienciación entre los jóvenes.

During 2011–2012, a total of 1008 serum samples from randomly selected inhabitants of seven Croatian counties located on the Adriatic Coast were tested for the presence of chikungunya virus (CHIKV) IgG antibodies using indirect immunofluorescence assay.
Nine participants (0.9%) from four counties were found to be seropositive to CHIKV. Seroprevalence varied from 0.5% to 1.8% between counties. Additionally, a total of 3,699 mosquitoes were captured in 126 localities from August 16 to September 24, 2011. Three mosquito species were found: Ae. albopictus (3010/81.4%), Cx. pipiens (688/18.6%) and only one specimen of the Cs. longiareolata. Female mosquitoes (N = 1,748) were pooled. All pools tested negative for CHIKV RNA using a real-time RT-PCR.

Published: July 2015

Background
Lucid dreams are frequently pleasant and training techniques have been developed to teach dreamers to induce them. In addition, the induction of lucid dreams has also been used as a way to ameliorate nightmares. On the other hand, lucid dreams may be associated with psychiatric conditions, including Post-Traumatic Stress Disorder (PTSD) and Reward Deficiency Syndrome-associated diagnoses. In the latter conditions, lucid dreams can assume an unpleasant and frequently terrifying character.

Case presentations
We present two cases of dramatic alleviation of terrifying lucid dreams in patients with PTSD. In the first case study, a 51-year-old, obese woman, diagnosed with PTSD and depression, had attempted suicide and experienced terrifying lucid nightmares linked to sexual/physical abuse from early childhood by family members including her alcoholic father. Her vivid “bad dreams” remained refractory in spite of 6 months of treatment with Dialectical Behavioral Therapy (DBT) and standard pharmaceutical agents which included prazosin, clonidie and Adderall. The second 39-year-old PTSD woman patient had also suffered from lucid nightmares.

Results
The medication visit notes reveal changes in the frequency, intensity and nature of these dreams after the complex putative dopamine agonist KB220Z was added to the first patient’s regimen. The patient reported her first experience of an extended period of happy dreams. The second PTSD patient, who had suffered from lucid nightmares, was administered KB220Z to attenuate methadone withdrawal symptoms and incidentally reported dreams full of happiness and laughter.

Conclusions
These cases are discussed with reference to the known effects of KB220Z including enhanced dopamine homeostasis and functional connectivity of brain reward circuitry in rodents and humans. Their understanding awaits intensive investigation involving large-population, double-blinded studies.
Enchondroma of the Distal Phalanx
Authors: Ivey Christopher J. , Kane Edward J. 
Published: July 2015

The patient was a 29-year-old woman who was evaluated by a physical therapist in a direct-access capacity for an enlarged distal phalanx on the fourth digit of her left hand. After discussing the patient's presentation with an orthopaedic hand surgeon due to concern for nonmusculoskeletal pathology, radiographs were ordered and findings were thought to be consistent with an enchondroma, which is a benign lesion commonly seen in the hand.

Compliance to Hypertension Treatment in Residents of a Fishermen Colony in District Kollam, Kerala
Authors: Aslami Ahmad Nadeem , Jobby Abraham 
Published: July 2015

Background: Hypertension is an important underline cause for cardiovascular deaths worldwide. Treatment compliance for hypertension depends on a lot of factors. There is paucity of studies about awareness and compliance to antihypertensive treatment particularly in coastal areas. Our aim was to know the awareness, treatment, compliance and control of blood pressure among hypertensive patients in a fishermen colony of Jonakapuram, Kollam. Material and Methods: A community based cross sectional study was done in a coastal area of Kollam. A house-to-house survey was conducted with a pretested semi-structure questionnaire. Three blood pressure readings were taken and mean value was calculated. The study period was one year. Data was analyzed by using Statistical Package of Social Sciences 12. Appropriate statistical tests were applied. Results: A total of 276 persons were found to be hypertensive. The percentage of awareness, treatment among aware subjects, treatment compliance and control of BP among patients taking anti-hypertensives was 71.74%, 85.86%, 73.53% and 50.58%. The awareness and treatment was significantly more among females as compared to males. The advices received by the patients were medicines, diet restrictions and lifestyle changes. Financial problems were the main reason for non-compliance to medicines. Conclusion: Nearly 3/4th of the study subjects were aware that they have hypertension. Monetary problems were an important cause for non-compliance. Half of the patients taking antihypertensive medication had their blood pressure uncontrolled. Patient’s economic status should be considered before advising them medications. This will increase compliance and help in improving the quality of patient care.

Left pterional craniotomy for thrombectomy and clipping of ruptured left MCA giant aneurysm
Authors: Couldwell William T. , Cutler Aaron , Neil Jayson A. 
Published: July 2015

Giant aneurysms present a challenge to cerebrovascular surgeons on many fronts. These lesions have significant mass effect on surrounding tissues and are often partially thrombosed with thickened or calcified walls; these difficulties are amplified in cases of subarachnoid hemorrhage. The treatment of these lesions often requires debulking or resection of the aneurysm with or without trapping and bypassing the aneurysm segment. The case presented is of a man with a ruptured giant left middle cerebral artery (MCA) aneurysm presenting with seizure. The treatment of this giant aneurysm involves dissection, opening and internal evacuation including the use of ultrasonic aspiration, resection, and clipping. The patient was given aspirin preoperatively in preparation for possible superficial temporal artery-MCA or saphenous vein bypass if clipping was not possible. Vessel patency was evaluated using intraoperative Doppler and indocyanine green angiography. Intraoperative somatosensory and motor evoked potential monitoring is performed in all cases. Postoperatively, the patient was neurologically intact. At 1 year his modified Rankin Scale is 1, with his only symptom being intermittent headache.The video can be found here: http://youtu.be/8dimNdiIObE.

Authors: Kalakoti Piyush , Bir Shyamal C. , Murray Richard D. , Ahmed Osama , Nanda Anil 
Published: July 2015

Broad-necked middle cerebral artery aneurysms present unique challenges for the vascular neurosurgeon, who must contend with smaller vessels and often a complex clipping strategy. Due to their superficial location, these lesions are still commonly selected for microsurgical clipping. We present a case of a 42-year-old woman with significant vascular disease with a right middle cerebral artery aneurysm. We discuss the key surgical steps, demonstrate the microsurgical dissection and intraoperative rupture encountered and the final clipping strategy, as well as the postoperative course in this operative video presentation.The video can be found here: http://youtu.be/qZ2gvqz7XdQ.
Ophthalmic artery aneurysm treated by surgical clipping and balloon-assisted temporary carotid occlusion
Authors: Dehdashti Amir R. 
Published: July 2015

A 29-year-old woman is diagnosed with a large broad-base right ophthalmic artery aneurysm. Despite an intact visual field, she complained of mild right visual blurriness. Between endovascular and surgical treatments, surgery was favored due to her young age. It was decided to perform the surgery with simultaneous endovascular temporary carotid balloon occlusion. A right pterional craniotomy and intradural anterior clinoidectomy were performed, the balloon was positioned in the petrous carotid, and the distal durai ring was opened exposing the proximal neck. Under temporary proximal carotid balloon occlusion and distal carotid clip occlusion, the aneurysm was fully dissected and clipped. Intraoperative angiogram confirmed complete aneurysm occlusion and patency of the ophthalmic artery. The patient's neurological exam remained unchanged.The video can be found here: http://youtu.be/BIQKTl9bDqA.

Published: July 2015

Aneurysms of the posterior circulation remain challenging lesions given their proximity to the brainstem and cranial nerves. Many of these aneurysms may best be approached through a retrosigmoid-suboccipital craniectomy with a far-lateral transcondylar extension. In this narrated video illustration, we present the case of a 37-year-old man with an incidentally discovered right-sided anterior inferior cerebellar artery (AICA) aneurysm. Diagnostic studies included CT angiography and cerebral angiography. A suboccipital craniectomy and far-lateral transcondylar extension were performed for microsurgical trapping and excision of the AICA aneurysm. The techniques of the retrosigmoid craniectomy, C-1 laminectomy, condylectomy and microsurgical trapping of the aneurysm are reviewed.The video can be found here: http://youtu.be/JiM3CXVwXnk.

Published: July 2015

We present surgical clipping of a giant middle cerebral artery aneurysm. The patient is a 64-year-old woman who suffered subarachnoid hemorrhage in 2005. She was treated with coiling of the aneurysm at an outside institution. She presented to our clinic with headaches and was found on angiography to have giant recurrence of the aneurysm. To allow adequate exposure for clipping, we performed the surgery through a cranio-orbito-zygomatic (COZ) skull base approach, which is demonstrated. The surgery was performed in an operating room/angiography hybrid suite allowing for high quality intraoperative angiography. The technique and room flow are also demonstrated.The video can be found here: http://youtu.be/eePcyOMi85M.
Microsurgical technique of symptomatic intracavernous aneurysm
Authors: Liao Chih-Hsiang , Lin Chun-Fu , Hsu Sanford PC. , Chen Min-Hsiung , Shih Yang-Hsin 
Published: July 2015

Symptomatic intracavernous aneurysm is rare. Cranial nerves in the cavernous sinus are subjected to the mass effect of an expanding aneurysm. Microsurgical clipping is the treatment of choice to relieve compressive cranial neuropathy. In this video, the authors present a case of intracavernous aneurysm causing diplopia, ptosis, and facial numbness. The patient was operated on via a pretemporal transclinoid-transcavernous approach. The aneurysm was completely obliterated through direct clipping. There were no new-onset neurologic deficits and complications after the operation. Complete recovery of the diplopia, ptosis, and facial numbness was observed at the 6-month postoperative follow up.The video can be found here: http://youtu.be/4w5QUoNIAQM.

Published: July 2015

Giant posterior circulation aneurysms pose a significant challenge to neurovascular surgeons. Among various treatment methods that have been applied individually or in combination, clipping under hypothermic circulatory arrest (HCA) is rarely used. We present a 62-year-old man who initially underwent coil occlusion of the right vertebral artery (VA) for a 2.5 cm giant vertebrobasilar junction (VBJ) aneurysm. His neurological condition had declined gradually and the aneurysm grew to 4 cm in size. The patient underwent clip reconstruction of giant VBJ aneurysm under HCA. His postoperative course was prolonged due to his preexisting neurological deficits. His preoperative Modified Rankin Score was 5, and improved postoperatively to 3 at three and six months, and to 2 at one year.The video can be found here: http://youtu.be/L53SiLV8eJY.
ICA aneurysm surgically treated utilizing a choroidal to PCOM bypass and vein bypass
Authors: Patel Nirav J. , Morgan Michael K. 
Published: July 2015

This video shows the surgical repair of a 2.3 cm ICA aneurysm found in a 58-year-old woman, who presented for right eye vision changes. The patient underwent a right modified orbitozygomatic craniotomy and saphenous vein bypass from the common carotid to the temporal M2. The aneurysm was then opened and repaired. However, since the anterior choroidal artery was not filling, a salvage bypass between the anterior choroidal and the PCOM was done. Both bypasses were patent and the patient has done well with a mRS of 1 for vision symptoms.The video can be found here: http://youtu.be/ciMyzfXgo8I.
Clipping of posteriorly projecting large posterior communicating aneurysm via transsylvian anterior temporal approach
Authors: Yamamoto Junichi 
Published: July 2015

Clipping of a posterior projecting large posterior communicating aneurysm via transsylvian anterior temporal approach is presented. To expose and clip this large aneurysm, retraction of the temporal lobe is required via the conventional pterional approach. In this video, we demonstrate microsurgical techniques as to how to dissect and mobilize the sylvian veins as well as a bridging vein to the sphenoparietal sinus, and the middle cerebral artery branches to the frontal lobe side. After the microsurgical dissection, a wide anteriolateral temporal space is obtained without significant temporal lobe retraction. The aneurysm was completely obliterated via this approach.The video can be found here: http://youtu.be/vU9Nxm7Yn-A.
Microsurgical confirmation of perforating arteries arising from the fundus of a posterior communicating artery aneurysm

Published: July 2015

Perforating arteries rarely project from the fundus of an aneurysm. We present the case of a 35-year-old woman who was found to have a right posterior communicating artery (PCOM) aneurysm via catheter angiography. Superselective microcatheter angiography revealed that perforating arteries arose from the aneurysm fundus that supplied the anterolateral thalamus. Microsurgical exploration confirmed several small perforating arteries arising from the aneurysm dome as well as an atretic distal PCOM artery. Given the complex anatomy, the lesion was unsuitable for clipping. We propose that this aneurysm represents a developmental variant whereby the proximal PCOM artery becomes atretic and terminates in PCOM perforators.The video can be found here: http://youtu.be/iDcp9fsDjq4.
“Picket Fence” clipping technique for large and complex aneurysms
Authors: Davies Jason M. , Lawton Michael T. 
Published: July 2015

The “picket fence” clipping technique is a method for clipping large aneurysms when conventional clipping across the neck is not feasible, either due to complex anatomy, atherosclerosis, calcification, or compromise of branch origins. This has also been described as a dome fenestration tube. Parallel straight clips, simple and/or fenestrated, are stacked vertically from dome to neck with the tips reconstructing the neck. In this video, the “picket fence” clipping technique is demonstrated on a large middle cerebral artery (MCA) aneurysm. A total of 14 clips reconstructed the neck, completely occluding the aneurysm and preserving outflow in all branch vessels.The video can be found here: http://youtu.be/0N5rYR6Op8Y.
Microsurgical management of a large ICA bifurcation aneurysm
Authors: Rangel-Castilla Leonardo , Spetzler Robert F. 
Published: July 2015

A 70-year-old man with progressive visual disturbances, left superior quadrantanopsia, and right-sided papilledema underwent imaging that demonstrated a right internal carotid artery (ICA) terminus aneurysm with third-ventricle mass effect and ipsilateral optic nerve and chiasm compression. We performed a right modified orbitozygomatic craniotomy, with proximal control and dissection of the aneurysm and small perforator arteries. Temporary ICA and anterior cerebral artery (ACA) clips allowed placement of a large curved permanent clip, reconstructing the ICA bifurcation and maintaining adequate patency of the ACA and middle cerebral artery. Complete aneurysm obliteration was confirmed by intraoperative indocyanine green angiography and postoperative CT angiography.The video can be found here: http://youtu.be/5WEEgmA-g2A.
k-jump: A strategy to design publicly-known algorithms for privacy preserving micro-data disclosure
Authors: Liu Wen Ming , Wang Lingyu , Zhang Lei , Zhu Shunzhi 
Published: July 2015

Abstract Data owners are expected to disclose micro-data for research, analysis, and various other purposes. In disclosing micro-data with sensitive attributes, the goal is usually two fold. First, the data utility of disclosed data should be maximized for analysis purposes. Second, the private information contained in such data must be to an acceptable level. Typically, a disclosure algorithm evaluates potential generalization functions in a predetermined order, and then discloses the first generalization that satisfies the desired privacy property. Recent studies show that adversarial inferences using knowledge about such disclosure algorithms can usually render the algorithm unsafe. In this paper, we show that an existing unsafe algorithm can be transformed into a large family of safe algorithms, namely, k-jump algorithms. We then prove that the data utility of different k-jump algorithms is generally incomparable. The comparison of data utility is independent of utility measures and syntactic privacy models. Finally, we analyze the computational complexity of k-jump algorithms, and confirm the necessity of safe algorithms even when a secret choice is made among algorithms.
