Authors: Russo S. , Yaber Grass M. A. , Fontana H. C. , Leonelli E. 
Published: July 2018

Aphids and thrips are very important pest species of many greenhouse and field plants in the world. In recent years, there have been attempts to identify plants for their insecticidal property with a view to find out suitable alternatives to the indiscriminate use of chemical pesticides, which are a risk for human health and the environment. The aim of this work was to evaluate the insecticidal effect of Eucalyptus globulus Labill essential oil (EO) against Aphis nerii Boyer de Fonscolombe (Hemiptera: Aphididae) and Gynaikothrips ficorum Marchal (Thysanoptera: Ploeothridae). The EO was extracted by hydrodistillation and the bioassay was evaluated by toxicity contact method, using solutions at different concentrations and for different time intervals. The EO was more toxic to G. ficorum (LC50 = 0.031?L cm-2) than A. nerii (LC50 = 0.099?L cm-2) on filter discs at 12 h of exposure. These results suggested that EO from E. globulus constitute a good alternative for the control of A. nerii and G. ficorum, considering their insecticidal effects at low applied concentrations and for short periods of time.

El objetivo fue valorar el efecto de dietas a base de torta de palmiste sobre el rendimiento productivo, calculando el incremento de peso (IP), incremento de peso relativo (IPR), tasa de crecimiento (TC), tasa de crecimiento incremental (TCI), conversión alimenticia (CA), digestibilidad aparente de la materia seca (MS), proteína (PB) y energía bruta (EB), así como, el costo de esta alimentación y la mortalidad del pez nativo vieja colorada en la etapa de cría. Los peces fueron alimentados con cuatro dietas (0, 4, 8 y 12% de palmiste) y cuatro repeticiones por tratamiento, por 30 días, alojados en 16 jaulas en un estanque. Se determinaron: el peso final (PF), IP, IPR, TC, TCI, CA, los coeficientes de digestibilidad MS, PB y EB, costos de alimentación y mortalidad. No se encontraron diferencias significativas en el PF, IP, IPR, TC Y TCI de la vieja colorada, entre los tratamientos T1, T2 y T3 de inclusión de la torta de palmiste; solo la dieta con mayor porcentaje de inclusión (T4) mostró unos peores resultados con respecto a la dieta T1. La CA presentó un mayor valor en la dieta testigo en comparación con la dieta T2 (p<0,05). El T4 evidencio la peor conversión alimenticia (p>0,05). A medida que se incrementó el % de palmiste el costo de la dieta disminuyó significativamente. La inclusión en la dieta de la vieja colorada de hasta un 8% de palmiste no afectó a los parámetros de rendimiento productivo estudiados. Además, se abarata la dieta significativamente

Head injury is a leading cause of death in young age group. Extra Dural hematoma, a complication of head injury, is often fatal if not treated in time. The surgical outcome of EDH is dependent upon many variables including preoperative GCS, time between injury and surgery, associated intracranial injuries, anisocoria and hematoma volume. In order to reduce the mortality near to nil, it is essential to determine the magnitude of effect of affecting factors on surgical outcome which will also help us in preoperative counseling and prioritizing the operative candidates. This study was conducted determine the factors affecting surgical outcome of traumatic intracranial extradural Hematoma in Punjab Institute of Neurosciences/ Lahore general hospital, Lahore. It was a Cross sectional study conducted for 3 years from 28th May 2012 to 28th May 2015.The study was conducted on the patients admitted through emergency and diagnosed as Extramural hematoma. These patients underwent surgical evacuation of EDH on emergent basis and outcome was measured by Glasgow Outcome Scale (GOS) after 48 hours of surgery. Using GOS, good surgical outcome was observed in 80.9% (157 out of 194) patients. Preoperative GCS, anisocoria, hematoma volume, associated intracranial injuries and time between injury and surgery were the factors affecting the outcome significantly (p value=0.000) while age and sex of the patient had no significant effect. In Conclusion, good surgical outcome is associated with patients with solitary Extra Dural Hematoma of volume less than 60 ml, preoperative GCS more than 8, absence of anisocoria and undergoing surgical evacuation within 6 hours of injury.

Published: July 2018

Objective: To evaluate the result of microsurgical excision of vestibular schwannoma by retrosigmoid approach and to correlate the facial nerve outcome with the tumor size.Methods: Retrospective analysis of 84 patients with cerebello-pontine angle lesions (57 vestibular schwannomas) operated at National Institute of Neurological and Allied Sciences, Nepal, from Baisakh 2066 to Chaitra 2073 (eight years). Facial nerve outcomes as per the House and Brackmann grading at six months follow-up were recorded and correlated with tumor size.Result: The mean tumor size was 4.32 ± 1.23 cms and 48 (84.2%) of the patients had tumor size more than 3 cms. Patients presented late with papilloedema documented in 42.1% and preoperative ventriculoperitoneal shunting required in 31.57% patients. Of the patients whose facial nerve functions could be followed up, all patients with tumors < 3cm diameter had good House and Brackmann facial nerve outcome (grade I to III). Larger tumors had poorer facial nerve outcomes; however statistical significance could not be reached. (Fischer Exact test, p-value: 0.077). There were two mortalities (3.5%), one following cavity rebleed and one following malignant brain swelling.Conclusion: Retrosigmoid approach is a versatile surgical corridor to excise large vestibular schwannomas with minimal complications and larger tumors have poorer facial nerve outcomes.

Published: July 2018

The aim of this study was to evaluate (surgical) visual outcomes in patients treated via supraorbital keyhole eyebrow incision approach. Data from 14 patients with TSMs (Tuberculum Sellae Meningioma) who underwent microsurgical treatment by a supraorbital keyhole eyebrow skin incision between September 2006 and September 2013 were retrospectively collected and analyzed. Patients were analyzed on the basis of clinical, radiological, and surgical factors that appeared to affect the outcome. To quantify the extent of ophthalmological disturbances Visual impairment score was used to analyze visual acuity and visual fields, which range from 0 (best) to 100 (worst). Change in visual function was assessed as the main outcome. The mean age of the 10 women and 4 men enrolled in the study was 56.50years (range, 42~74 years). The presenting symptom was asymmetrical visual loss in 71.4% of the patients.And examination revealed decreased visual acuity (Snellen notation) in 100% and impaired visual fields (Goldmann perimetry) in 58.3 % (7/12 cases, central scotoma and temporal anopia n=1, classical bitemporal hemianopia n=4, incongruent homonymous hemianopia n=2 , 2 cases data N/A) of the patients. Simpson grades I resection via a supraorbital keyhole eyebrow skin incision approach, were achieved in 100% of the patients. Quality of life was assessed according to Karnofsky scale and was 86.67 (range: 70~100). The mean follow-up duration was 51.73 months (range: 27~91 months).No recurrent tumors were observed during this period. According to the findings of this study, this approach provides a pleasing cosmetic outcome and also decreases brain manipulation while minimizing the likelihood of procedure-related morbidity. A favorable visual outcome was observed in most of the patients in the late postoperative period. Nepal Journal of Neuroscience, Volume 14, Number 3, 2017, page : 26-32
Post Traumatic Chronic Encapsulated Intracerebral Hematoma in a Child: Case Report and Brief Review of Literature
Authors: Roka Yam Bahadur , Karki Mohan 
Published: July 2018

Chronic encapsulated intracerebral hematoma (CE-ICH) is an uncommon pathology that presents with headache, seizure, focal neurological deficits, or as a tumor. Trauma as a cause for CE-ICH is even rare and we believe this is the first case report as “trauma causing chronic encapsulated intracerebral hematoma “search in PubMed did not reveal any results. Repeated micro-hemorrhages in the CM or AVM are supposed to cause this lesion which progress from an earlier encapsulated phase to a thick capsulated stage with edema and clinical symptoms. CT or MRI is the diagnostic modality and it mimics, tumor, AVM, CM, angiomableed, cerebral abscess, metastatic mass or neurocysticercosis. Burr hole, mini-craniotomy, craniotomy, CT guided stereotactic aspiration or endoscopic excision are some options with equally good results. The present case with history of trauma was managed successfully with craniotomy with no recurrence for past one year. Nepal Journal of Neuroscience, Volume 14, Number 3, 2017, page: 46-48
