Authors: Singhvi Shreyans D. , Singh Preksha , Khan Rafe , Patel Monila , Acharya Pavan
Published: March 2020

Microscopic polyangiitis (MPA) is a small blood vascular disorder, but with presence of no granulomas. This is a pauci- immune disorder vessels which lead to vascular inflammation and then later, it can lead to organ microscopic polyangiitis. This disorder affects multiple organs as it is a systemic disease, but usually presents with renal dysfunction - rapidly progressive glomerulonephritis. There is a possible association of p- ANCA (antineutrophil cytoplasmic antibodies) and can help with the diagnosis of the disorder. This case report is of a 70-year-old female, who presented with symptoms of diffuse pulmonary hemorrhage. After routine blood examination, radiological examination- X ray (chest) and HRCT- thorax, routine urine examination, ANA and ANCA test, the final diagnosis of microscopic polyangiitis with no renal involvement was made. The case was given immunosuppressant therapy and the patient reported of mitigation of symptoms. This case report is unique as MPA usually presents with renal dysfunction, but in this case, the patient had particularly pulmonary involvement with completely normal renal function. This case report will help future physicians for quick diagnosis of similar cases and treatment for the same.

Authors: Abualiat Abdullah , Edris Hala , Alfadni Salaheldin , Aziz Tariq , Hussein Mahmoud
Published: March 2020

Pyoderma Gangrenosum (PG) is a rare chronic immune-mediated inflammatory dermatosis manifested as painful skin ulceration, commonly affecting the lower limbs. The pathogenesis of the disease is complex. Abnormalities in neutrophil function, dysregulation of the innate immune system, and Tumor Necrosis Factor (TNF) were postulated. An underlying associated systemic disease was reported in more than 50% of PG patients, including inflammatory bowel disease, rheumatoid arthritis, and malignancies, with few cases reported an associated thyroid disease. Authors report a case of extensive PG associated with both ulcerative colitis and thyrotoxicosis co-morbidities not mentioned before in one patient. The patient was successfully treated with the anti-TNF alpha infliximab.
Knowledge, attitude and practice of laparoscopic surgery among medical doctors in Port Harcourt, Nigeria
Authors: Ijah Rex F. O. A. , Manuel Amabra Dodiyi
Published: March 2020

Background: The use of minimal access techniques to achieve similar objectives as in open surgical procedures has witnessed a steady progress in the last two decades. The efficacy and safety of this mode of surgery has long been established. Medical doctors are not only members of the society; with their level of knowledge, their opinion is a strong mirror image of the pulse of the patients they treat. Aim of the study was to ascertain the knowledge, attitude, extent of practice, and factors affecting laparoscopic surgery among medical doctors in Port Harcourt, Nigeria.Methods: A cross sectional study of four hundred and fourteen (414) practicing medical doctors was conducted. Using stratified sampling method, self-administered semi-structured questionnaires was distributed to respondents in Port Harcourt in 2018. Data obtained was analysed using the Statistical Package for the Social Sciences (SPSS) version 20.0.Results: Knowledge of laparoscopic surgery among respondents was 89.6% (371). Three hundred and twelve respondents (75.4%) were willing to pay if such surgery is necessary and offered in Port Harcourt. Only 2.4%. of respondents asserted that laparoscopic surgery services are offered regularly in their hospital. Only 1 respondent (0.2%) was willing to pay ₦151,000.00 - 200,000.00 ($430 - $570) for commonly performed laparoscopic abdominal surgical procedures.Conclusions: Willingness to accept and knowledge of laparoscopic surgery was relatively high among medical doctors, hence a high prospect for laparoscopic surgery practice in Port Harcourt is therefore likely. The practice of laparoscopic surgery seems low and willingness to pay, even among doctors seem to be a challenge.

Authors: Deshmukh Santoshkumar N. , Parikh Hirav P.
Published: March 2020

Background: Surgery is the mainstay of the treatment for perforated duodenal ulcer by closing the perforation with or without omental patch. There are no controversies in the surgical treatment of perforated duodenal ulcer but the best approach to surgery is still debatable. Advances in minimal access surgery has made it possible to close the perforated duodenal ulcer laparoscopically. The present study was conducted to compare the results of open and laparoscopic repair of perforated duodenal ulcer in terms of operative time, postoperative pain, hospital stay, and post-operative complications etc.Methods: The study was conducted in Dr. V. M. Government Medical College and Hospital located in Solapur (Maharashtra) from December 2008 to December 2010. It was a prospective comparative study. Patients were randomly divided into 2 groups alternately where group A and B were operated by conventional and laparoscopic techniques respectively and their outcomes were compared.Results: Most commonly affected age in this study was 51 to 60 years with male preponderance. Post-operative pain, analgesic requirement, wound infection, hospital stay, was significantly less in laparoscopic group as compared to open group (p<0.05).Conclusions: Laparoscopic repair of perforated duodenal ulcer is safe and feasible in properly selected patients and has superior results as compared to open surgery.

Authors: Khan Hosni Mubarak , Ramesh B. S. , Bobburi Viraja
Published: March 2020

Background: The Desarda repair for inguinal hernias is a new tissue-based technique. Application of the external oblique muscle aponeurosis in the form of un-detached strip has been established as a new concept in tissue-based hernia repair.Methods: A prospective study was conducted among 126 cases with 148 inguinal hernias repaired by Desarda’s technique for a period of 3 years in Dr. B. R. Ambedkar Medical College and Hospital, Bangalore, Karnataka, India. The details pertaining to duration of hospital stay, pain, ambulation and complications were recorded.Results: The mean age of the patients was 38.4 years. Mean operating time was 62.5 min for unilateral and 123 min for bilateral hernias. About 97.8% patients were ambulatory within 6.42 hours and were freely mobile within 19.26 hours after surgery. About 96.4% patients returned to work within 6-14 days. About 91.26% patients were discharged on same day. The mean hospital stay duration of the patients was 1.11 days. Postoperative pain on movement out of bed was described as mild and tolerable in 92.6% patients on day 1. Two patients had seroma that subsided on its own. There were no long-term complications, recurrence of the hernias or chronic groin pain.Conclusions: The results of this new technique (Desarda repair) using continuous absorbable sutures appear promising. The continuous suturing saves time and just one packet of suture material without mesh saves cost.

Authors: Metta Vipul , Nichkaode Prabhat B. , Panchbhai Sunil V. , Charan Sai , Purohit Aishwarya
Published: March 2020

Background: Chronic non healing ulcers are a challenge to the patient and health care professional. They require special care and intensive treatment often for prolonged periods. These ulcers do not generally heal with conventional types of treatment within a reasonable time period and need special types of treatment like collagen particles, vacuum dressing, chemical debridement etc. The aim of the study was to compare the effect of sterile collagen particles with saline dressings in treatment of chronic non healing ulcers.Methods: 30 test subjects were dressed using sterile collagen particles and 30 controls using saline gauze on day 2 and every 3rd day. The condition of the ulcer was followed up using the Bates-Jensen wound assessment score (BJWA score).Results: BJWA score was significantly lesser at 4th week in test group. The p value was 0.00021. Test group mean score was 17.23 and for control group it was 21.467. BJWA score was significantly lesser even at 8th week in Test group. The p value was 0.00026. Test group mean score was 12.47 and control group it was 17.43. This signifies that healing rate is better in test group compared to control group.Conclusions: Comparing the components in BJWA score we can conclude from our study that; collagen dressings are superior to saline dressing in all type of ulcers and irrespective of gender and age of a person. The best response was seen in non diabetic ulcer without Saphenofemoral incompetence who are non smokers.

Authors: Thakur Bhushankumar A. , Mukhamale Vivek , Deotale Snehal
Published: March 2020

Background: Trans abdominal preperitoneal (TAPP) a novel approach for inguinal hernia was introduced by Arregui (1991) and Dion in early 1990’s has brought the revolutionary change in the era of hernia surgery over open preperitoneal inguinal hernia repair procedure introduce by Stoppa. Based on this we have done single institution retrospective study of TAPP and open preperitoneal procedure for inguinal hernia.Methods: This study was single institution retrospective study, where we have analyzed the data of 93 male and 7 female patients out of which 50 underwent standard TAPP procedure and 50 patients who underwent open preperitoneal procedure for inguinal hernia, with median 1 year of follow up. Their data analyzed for demographics, surgical site occurrence and short terms recurrence.Results: 100 patients with mean age of 55 years, median ASA of 1, ratio of left: right: bilateral for open 18:30:2 and for laparoscopic 26:20:4. Mean time for surgery was 102.3 min for open and 142.4 mins for TAPP. There was surgical site infection in 3 patients operated by open procedure and 2 patients in TAPP procedure. 4 patients from open procedure group and no one with TAPP group developed seroma which were managed conservatively and resolved at 6 weeks and 8 weeks. One recurrence in TAPP group patient at the 1 week follow.Conclusions: Open preperitoneal repair is hence a technique as effective as laparoscopic hernia repair with a minimal learning curve, ability to be performed under regional anaesthesia and cost effective. It can hence be used to carry out inguinal hernia repairs effectively in rural areas.

Authors: Lamani Yamanur P. , Reddy M. Amarnath , Kalburgi E. B. , Suhas B. S.
Published: March 2020

Background: Split skin grafting is widely used surgical procedure for the treatment of ulcers. Graft survival depends on number of factors like vascularity, wound infection etc, diabetes is associated with endothelial dysfunction, neuropathy, wound infection which collectively affect the graft survival. Objective of this study was to compare the amount of graft uptake, the post-operative complications and survival of split thickness skin graft in diabetic and non-diabetic ulcer.Methods: In our prospective comparative study total 112 patients with ulcer were included of which 56 were diabetic and 56 were non-diabetic. All of t7hem underwent split skin grafting as part of their wound management. Comparison was made between two groups in terms of amount of graft uptake, post-operative wound infection, revisional surgery, donor site infection.Results: Compared with non-diabetics, diabetics have significantly less graft uptake (p<0.001). out of 56 patients in diabetic group 4 (66.7%) underwent revisional surgery, out of 56 patients in non-diabetic group 2 (33.3) patients underwent revisional surgery (p value is <0.68) which is statistically insignificant. 3 (60%) out of 56 in diabetic group developed post-operative graft infection, 2 (40%) out of 56 in non-diabetic group developed graft infection (p=1, not significant). One patient in the study developed donor site infection. Among 112 cases, only 1 case had donor site infection with diabetic.Conclusions: Diabetes is associated with poor graft uptake and post-operative complication rates in patients undergoing split skin grafting.
Predictive factors for intraoperative excessive bleeding in Grave’s disease
Authors: Srinivas A.
Published: March 2020

Background: Grave’s disease frequently results in and is the most common cause of hyperthyroidism. It also often results in an enlarged thyroid. It also known as toxic diffuse goiter, is an autoimmune disease that affects the thyroid. This study evaluates all the factors that cause intra-operative blood loss and how it affects the grave’s disease.Methods: This study was conducted on 100 patients with Grave’s disease, who underwent thyroidectomy during the period from May 2010 to April 2016.Results: The majority of patients were females which constitute about 76.3% with a median age of 33 years. The median period between the onset of the disease and operation was 15 months. Weight of thyroid in grams was 40. Post-operative hospital stay was 3 days. Univariate analysis revealed that the strongest correlation of amount of intraoperative blood loss (AIOBL) was noted with the weight of thyroid (p<0.001). Additionally, AIOBL was correlated positively with the period be- tween disease onset and surgery (p<0.001) and negatively with preoperative free T4 (p<0.01). Occurrences of postoperative complications, such as recurrent laryngeal nerve palsy or hypoparathyroidism, and postoperative hospital stay were not correlated with AIOBL.Conclusions: For Grave’s disease, for excessive bleeding during surgery, a large goiter presented as a predictive factor, and transfusion of blood should be considered in cases in which goiter weighs more than 200 g.

Authors: Raza Mohammed , Gupta Mohit
Published: March 2020

Sialolithiasis is the most common disease that affects the major salivary glands and occurs mainly in the submandibular gland (80-90%), and to a lesser degree in the parotid gland (5-20%). In literature many papers have been published regarding the parotid calculi and their treatment. However, data on salivary duct strictures management is less with variable opinion. We present a case of 45-year-old female with swelling of right parotid for 6 months, USG showed duct calculi with sialadenitis and sialogram showed large duct calculi with high grade strictures. Duct calculi was removed by intra-oral approach and parotidectomy was done as endoscopic management of strictures failed. This was highlighted case as parotid duct calculi along with high grade strictures are rare.

Authors: Madzharova Kalina I. , Beshkova Ana P.
Published: March 2020

Background: Vestibular evoked myogenic potential (VEMP) testing is used in the diagnosis of vestibular disorders. It is an objective method for testing the the otolith organs of the vestibular system. VEMP test is an additional method for diagnosing vestibular neuritis (VN). The combination of cervical VEMP (cVEMP) and ocular VEMP (oVEMP) testing has an advantage in long-term monitoring of patients with VN. The VEMP test is well-studied for adults but studies involving children are insufficient. The aim of this study was to analysis and evaluation of the results from VEMP testing of children diagnosed with vestibular dysfunction. Analysis and evaluation of the results from VEMP testing of children diagnosed with vestibular dysfunction.

Methods: History, examination of ENT organs, tone threshold audiometry, tympanometry, otoneurological examination, VEMP test.  

Results: Children with vestibular dysfunction who were examined showed changes predominantly in the oVEMP test. The upper branch of the vestibular nerve is affected.   

Conclusions: The VEMP test is an additional method for diagnosing patients with vestibular dysfunction. It is safe when used for children.

Authors: Pradhananga Rabindra Bhakta , Gyawali Bigyan Raj , Bhattarai Bebek
Published: March 2020

Background: Vestibular neuronitis is one of the common causes of peripheral vertigo. Mostly the diagnosis of this entity is on clinical grounds. With the advent of video head impulse test (VHIT), assessment of function of all the semicircular canals has been possible based on principle of vestibulo-ocular reflex (VOR). The rationale of our study was to identify the affected branch of vestibular nerve in cases with clinical suspicion of vestibular neuronitis by measuring VOR gain and saccades using VHIT.

Methods: This was a retrospective study carried out in the Department of ENT, Head & Neck Surgery of Institute of Medicine, Kathmandu, Nepal. Record files of patients who attended OPD between October 2017 to October 2018 with the clinical diagnosis of peripheral vestibular neuronitis were assessed. A total of 13 cases were included in the study. VHIT records of the cases were assessed for VOR gain and saccades. Normal contralateral canals were taken as control. Paired t-test was used to compare the statistical significance of gain asymmetry and presence of saccades between the affected side and normal side.  

Results: Of 13 cases, 11 had isolated involvement of lateral semicircular canal and 2 cases had isolated involvement of posterior semicircular canal. Average gain was 0.68 in both groups. Presence of overt and covert saccades was seen in all the affected canals.

Conclusions: VHIT, in cases with vestibular neuronitis, is a good test not only to confirm the diagnosis but also to identify the division of vestibular nerve involved.

Authors: Munjal Manish , Kaur Amanjot , Bajwa G. S. , Vohra Hitant , Sohi Akashdeep , Munjal Shubham
Published: March 2020

Background: Dacryocystography is a simple radiological procedure in which a radiographic water-soluble dye like iohexal or neohydriol is injected into the lacrimal system and free flow of dye is noted from the eyes into the nose and any restriction in the flow of indicates obstruction and site of the same.

Methods: This is a prospective study of role of dacryocystography in 31 cases of dacrocystitis who presented to the ENT outpatient clinic of Dayanand Medical College and Hospital over a period of 1.5 years i.e. from June 2016 to December 2017 who were planned for dacrocystorhinostomy. Patient was placed in dorsal decubitus position and local anaesthesia was administered. No. 15 catheter was connected to a syringe containing contrast medium and its ends are introduced into both lacrimal puncta. Head of the patient is fixed and the contrast medium was administered through both the puncta simultaneously and serial radiographs were obtained

Results: The role of dye study, prior to endoscopic dacrocystorhinostomy dacrocystography was studied in 31 subjects. Of the 22 subjects who underwent surgical intervention, 18 (81.8%) had a complete obstruction while 4 (18.2%) had a partial block.

Conclusions: Dacryocystography is a useful and cost-effective investigation to delineate the obstruction in the nasolacrimal system. It aids in confirmation of clinical diagnosis as well as making a diagnosis in doubtful cases.
Results of cartilage shield tympanoplasty in revision cases of myringoplasty
Authors: Wadhera Raman , Gupta Keshav
Published: March 2020

Background: Cartilage shield tympanoplasty (CST) is seen as a good option for revision surgery in cases of myringoplasty failure. Cartilage serves as rigid material which resists retraction. However, there have been concerns regarding hearing outcome and surveillance in follow up period.

Methods: A prospective study was conducted at our tertiary institute. 25 patients of either sex in age group of 18-50 years with one or more failed tympanoplasties underwent CST. Pre-operative and post-operative audiograms were obtained, and patients were regularly followed up to calculate graft uptake and hearing outcome. Quantitative data was analyzed by using Student t-test and for qualitative data chi square test was used.  

Results: The mean pre-operative pure tone air-bone gap was 25.09±8.10 dB while the mean postoperative pure tone air-bone gap was 13.47±5.18 dB, one case (4%) presented with failure as there was a residual perforation antero-inferiorly. Since it was a small residual perforation, it was planned for closure by fat myringoplasty. No complications were recorded. We obtained graft take rate of 96% and mean postoperative gain of 11.62±7.11 dB in PTA-ABG.

Conclusions: We recommend CST for revision cases of tympanoplasty.

Authors: Reddy D. Indraneel , Narayana M. Lakshmi , Viswambharan Vivek , Chaithanya N. Reddy
Published: March 2020

Background: Among all forms of tobacco, smokeless tobacco is known to be more carcinogenic than smoking according to various studies. Smokeless tobacco is consumed through various forms in our region like kaddipudi, gutkha, khaini, pan, etc. This study aims at evaluating the different chewing patterns of tobacco and to assess their impact on the oral mucosa.

Methods: The patients who attended ENT department with the habit of chewing tobacco were taken into this study after considering the inclusion and exclusion criteria. A detailed questionnaire including various habits and chewing patterns were filled and received from all the subjects, and a comprehensive ENT examination was done for them.  

Results: In our study, a total of 120 subjects were included who chewed tobacco in various combinations, which we divided into 6 categories; of which 97 users were under category 2 (betel leaf, betel nut, slaked lime and kaddipudi). Among 120 subjects, 35 had malignancy, 51 potentially malignant lesions, 30 early changes and 4 had no changes. There was a statistically significant correlation noted between the duration of chewing for >15 years (p=0.000); frequency of chewing >5 times/day (p=0.004) and also overnight tobacco placement (p=0.027) with the occurrence of potentially malignant lesions and malignancy.

Conclusions: In our study, the combination of betel leaf, betel nut, slaked lime with kaddipudi was the most commonly used combined form of smokeless tobacco. The duration, frequency of tobacco chewing, and overnight placement were statistically significant associated with potentially malignant lesions and malignant lesions.

 
A prospective analytic study of invasive fungal rhinosinsitis
Authors: Parmar Bhagirathsinh D. , Jha Sushil G. , Sinha Vikas , Chaudhari Nirav P. , Dave Gavendra P.
Published: March 2020

Background: Fungal sinusitis is more commonly found in immunocompromised patients with systemic illnesses, e.g., uncontrolled diabetes mellitus, chronic renal failure, patient on prolonged systemic steroid therapy, hematological malignancies, HIV/AIDS, etc. Invasive fungal sinusitis is subdivided into acute and chronic. Less than 4 weeks duration separates the acute stage from the chronic stage of the disease. Management of invasive fungal sinusitis consists of sinonasal debridement with or without Caldwell-Luc surgery followed by antifungal therapy.

Methods: Total 30 cases of both types of invasive fungal sinusitis were included in this study. The demographic profile, clinical presentation, underlying immunocompromised status, complication, mortality and management of all these 30 patients were analyzed.  

Results: Invasive fungal sinusitis was most commonly observed in 3rd and 4th decade of life with male predominance. Prolonged uncontrolled diabetic mellitus was the most common underlying immunocompromised status. Mucor was the most common isolated fungal species. Preseptal cellulitis was the most common complication.

Conclusions: For early detection of mucosal changes one has to do endoscopic examination in all immunocompromised patients with symptoms like headache, facial or periorbital pain and swelling, purulent nasal discharge, etc. All clinician should think vigilantly in immunocompromised patients with above symptoms or in pyrexia of unknown origin not responding to antibiotics. To reduce mortality, one has to go for immediate sinonasal debridement even in local anaesthesia also if patient is not fit for general anaesthesia.

 
Angiectatic nasal polyp diagnostic quandary of sinonasal malignancy
Authors: Kashaf Nur Afeena A. F. A. , Chin Andrew H. K. , Ibrahim Zambri M. , Rahman Irnawati W. A. , Rahman Shakir K. A.
Published: March 2020

Angiectatic nasal polyp (ANP) is a rare entity of inflammatory nasal polyp accounts for only 4 to 5% of all nasal polyp.It is often misdiagnosed as a malignant neoplasm due to its aggressive clinical presentation and radiological findings mimicking a neoplastic characteristic. achieving the diagnosis of ANP can be a challenge but crucial as management and prognosis of malignant and benign sinonasal tumour differs significantly. We describe a unique case of an ANP in a 33 year old gentleman presented with left sided nasal obstruction associated with blood stained nasal discharge, facial pain and left eye epiphora. There was proptosis of the left eye and his left nasolabial fold was obliterated due to a vague left cheek swelling. Clinical presentation was highly suspicious of malignancy. CT scan finding was also suggestive of malignant tumour with surrounding bony bowing and erosions, while MRI was reported as haemangioma. Post-surgery of left endoscopic medial maxillectomy, histopathology result was negative for malignancy. After revision of specimen done and further discussions, the diagnosis of ANP was made. Patient was postoperatively well with regression of symptoms along 5 months follow-up. ANPs are relatively uncommon pseudoneoplastic lesion that can cause a significant diagnostic dilemma as illustrated in this case. awareness of distinctive radiological and histopathological findings of ANP is important to establish the diagnosis and managed accordingly. However, little is known to guide the approach in such cases, therefore we find the case report to be noteworthy in this field.

Suriname: Natureza e Cultura - Memórias de uma experiência pessoal
Authors: Francisco Julio Bittencourt
Published: March 2020

O presente artigo é um relato de uma experiência pessoal de trabalho, quando passei 10 meses na vizinha República do Suriname, em 2001. Originário do Rio de Janeiro para onde voltava em um período de folga de duas semanas, ficava de cada vez 6 ou 7 semanas no país. Meu caminho de ingresso e retorno ao Suriname se dava via área do Rio de Janeiro até Belém/PA onde pernoitava, e de lá outra conexão aérea ao país vizinho, onde assumia meu posto de trabalho em Paramaribo ou Grönigen. Essas entradas e saídas do país, além das visitas que fiz à Belém, enriqueceu minha experiência pois a cada vez que voltava ao Suriname, no curso daquele ano, no período de folga em casa refletia sobre minhas relações com o país, colaboradores e fornecedores e, também, aclimatava-me com o Norte do Brasil e a população de Belém. No artigo, descrevo características culturais, geográficas, históricas e sociais do Suriname que, embora próximo ao Brasil, tem elementos totalmente diversos, apesar de semelhanças em seu passado colonial.

“Salvem o Hospital!”: Sobre patrimônios dissonantes da psiquiatria no Brasil e em Portugall
Authors: Borges Viviane
Published: March 2020

Abandonados, devolutos, subutilizados, os hospitais que tratarei aqui são patrimônios dissonantes, marcados por contradições e discordâncias quanto aos significados patrimoniais. O presente artigo parte da tessitura de dois museus: o Museu Bispo do Rosário de Arte Contemporânea, no Rio de Janeiro, e o Museu Miguel Bombarda, em Lisboa, tendo como fio condutor Arthur Bispo do Rosário e Jaime Fernandes. O objetivo é problematizar o processo de patrimonialização dos antigos hospitais psiquiátricos onde se localizam tais museus e onde viveram os personagens citados: a Colônia Juliano Moreira e o Hospital Miguel Bombarda. Assim, buscaremos perceber os sentidos históricos e patrimoniais a eles atribuídos, bem como o contraste em relação ao processo de apagamento em que se encontram no presente, problematizando o conceito de patrimônio hospitalar.

Published: March 2020

The use of veils for Muslim women is still menui pros and cons. The existence of different attitudes is in accordance with the beliefs, values and knowledge of religious beliefs. This study aims to explain the radicalization narratives that have weakened veiled Muslim women by building a more interesting and conceptual comparative narrative, namely, the narrative of de-radicalization. This study uses an ethnographic approach by analyzing the comments column of various parties who argue. The results showed that veiled Muslim women affiliated in @niqabsquad_official were not terrorists, not terrorist wives and not radical Islamists. The @niqabsquad_official account becomes a virtual veiled Muslim group oriented to Mulimah's hijrah concerning obedience to her religion. Each column of comments was filled with opinions and motivations of deradicalization which did not corner a particular religion.

Durante los meses de octubre y diciembre del año 2016, en el municipio de San José del Fragua (Caquetá-Colombia); se realizó un estudio sobre la identificación de la biodiversidad de macroinvertebrados acuáticos y su papel como bioindicadores de calidad del agua. Se establecieron 3 estaciones de monitoreo, con un total de 13 puntos de muestreo. Las variables físicas (temperatura, conductividad) y químicas (pH, STD, %OD) se evaluaron con un multiparámetros (Hanna), las muestras biológicas se recolectaron con redes surber (área muestreada 0,36 m2; ojo de malla 500 µm), redes de pantalla (área muestreada 1,6 m2; ojo de malla 350 µm) y redes D (área muestreada 0,9 m2; ojo de malla 500 µm), encontrándose 1357 individuos distribuidos en 13 órdenes y 36 familias, siendo el orden Trichoptera el más diverso con 9 familias (Glossossomatidae, Leptoceridae, Hydropsychidae, Odontoceridae, Calamoceratidae, Helicopsychidae, Philopotamidae e Hydroptilidae). La calidad biológica del agua se determinó implementando el índice BMWP/Col que arrojo resultados de aguas de buena calidad (Clase I). Concluyendo que el estado del agua del río Fragua Chorroso presenta buena calidad, con excelente capacidad de auto-depuración y apta para ser preservada y utilizada como un recurso para la conservación de la flora y fauna de la zona así como fuente abastecedora para el consumo human.

Se estima que más del 70% de los murciélagos son consumidores de insectos y por lo tanto contribuyen al control de poblaciones de insectos. Algunos de esos insectos pueden ser plagas en cultivos agrícolas o vectores de enfermedades. Por lo anterior, estudiar la dieta de los murciélagos insectívoros es importante para determinar su valor potencial para los humanos. En este trabajo de investigación, se analizó la dieta de una colonia de Saccopteryx leptura, una especie tolerante a ambientes urbanos neotropicales de zonas bajas.  Se recolectaron 24 muestras de heces de una colonia compuesta por entre siete y nueve individuos.  Entre las presas de S. leptura se encontraron insectos de los órdenes Hymenoptera (dos morfoespecies), Coleoptera (dos morfoespecies), Hemiptera (dos morfoespecies), Blattodea (una morfoespecie) y Lepidoptera (una morfoespecie),  siendo los dos primeros casi el 80% de las presas. Los últimos cuatro órdenes no habían sido registrados en la dieta de S. leptura. Entre las presas encontradas se incluyen coleópteros de la familia Curculionidae, y hemípteros de la familia Cicadellidae que con frecuencia son plagas en cultivos agrícolas. Estudios posteriores se centrarán en explorar estrategias para aprovechar los posibles servicios de este murciélago.

A pesar de su importancia como vectores de patógenos, es escasa la información sobre la biología y la ecología de los cicadélidos en Colombia. Por esta razón, se analizó la composición, la abundancia y la riqueza de Cicadellidae en el campus de la Universidad Militar Nueva Granada (UMNG) en Cajicá, Cundinamarca (Colombia). El campus se encuentra en un contexto rural exurbano. Se realizaron recorridos lineales de 50 m de longitud y 2 m de ancho, en tres zonas diferentes: pastizal corto, pastizal largo y meandro del río Bogotá. Los muestreos se llevaron a cabo entre las 11:30 h y las 12:30 h, durante tres semanas entre marzo y abril del 2015. Los insectos se capturaron con una red entomológica y se preservaron en etanol al 70%. Se capturaron un total de 2399 individuos, y fueron Amplicephalus funzaensis y Exitianus atratus las especies más abundantes. La similitud de la composición entre las tres zonas fue superior al 40% y la mayor similitud se presentó entre el pastizal largo y el meandro. No se encontró correlación entre el número de especies de Cicadellidae y el número de especies vegetales. La zona con menor riqueza fue el pastizal corto. Los datos sugieren que el corte frecuente del pasto afecta la estructura de la comunidad de Cicadellidae e incrementa la abundancia de vectores de fitoplasmas. Los resultados brindan una aproximación sobre la composición, la abundancia y la riqueza de cicadélidos en el campus de la UMNG, y se sugiere de qué manera las características del campus podrían manejarse.

En el presente trabajo de investigación se evaluó el porcentaje de rendimiento de la extracción etanólica de las plantas medicinales Alegría (Scutellaria incarnata) y Amansatoros (Justicia pectoralis), al aplicar dos métodos de maceración con y sin agitación, con el material vegetal entero y molido, además de realizarse pruebas en diferentes tiempos de maceración (6, 12, 24, 48 y 92 horas) hasta llegar a la estabilización de la extracción. Para el análisis de los datos se empleó un modelo de análisis estadístico correspondiente a un diseño experimental en bloques completos al azar con arreglo factorial (Anova), con el fin de determinar los valores estadísticos más relevantes en el proceso de extracción, de acuerdo con el factor tiempo, el método empleado y el tamaño de partícula. Tanto para la planta Alegría como para Amansatoros los resultados indican que, en la obtención del extracto etanólico, el mejor tiempo fue de 48 horas, con el uso de material molido y la aplicación de agitación. Estas condiciones permitieron obtener rendimientos del 37.000 y 37.600% para el extracto etanólico de Amansatoros y Alegría, respectivamente.
Fontes sociais do conhecimento físico: uma investigação com professores graduados em ciências biológicas
Authors: Silva Alexandre Leite dos Santos , Lopes Suzana Gomes , Takahashi Eduardo Kojy
Published: March 2020

Este artigo teve por objetivo ampliar a compreensão sobre a formação e os saberes dos professores de Ciências com relação ao conhecimento físico a partir dos sentidos atribuídos por eles às suas experiências formativas e da identificação das fontes sociais do seu conhecimento. Para isso, foi desenvolvida uma investigação narrativa com quatro professores de Ciências dos anos finais do Ensino Fundamental de escolas públicas de um município mineiro. A interpretação das narrativas aponta que os professores de Ciências participantes da pesquisa tiveram acesso a uma série de fontes sociais para a construção dos conhecimentos físicos utilizados em sua prática docente, sendo apontadas como mais significantes a formação escolar antes da graduação, a formação profissional continuada, as “ferramentas” de ensino e a experiência profissional. Os resultados apontam que há fragilidades na formação profissional inicial docente para o ensino de Física no Ensino Fundamental em Cursos de Licenciatura em Ciências Biológicas. Entretanto, as outras fontes sociais citadas também possuem fragilidades. Por isso, aponta-se neste estudo a importância da formação continuada para suprir a carência de conhecimentos físicos e o desenvolvimento da reflexão crítica de professores de Ciências para atuarem como atores sociais.

Published: March 2020

Objetivo: utilizando herramientas de revisiones sistemáticas, describir los efectos de la obesidad en el embarazo para la madre y el feto, así como describir las complicaciones perinatales, intraparto y posnatales en pacientes a las que se les ha practicado cirugía bariátrica.Metodología: se utilizó la base de datos Pubmed/Medline, los términos de búsqueda fueron: bariatric surgery AND/OR obstetric complications, pregnance, abortion, pregnancy outcomes, adverse pregnancy outcomes. Se hizo énfasis en guías de práctica clínica, se realizó búsqueda en sitios de sinopsis de la literatura médica del Database of Abstracts or Reviews of Effectiveness (DARE).Resultados: se seleccionaron 50 artículos, los cuales fueron sintetizados en la sección de resultados de la revisión. La cirugía bariátrica predispone a la isquemia intestinal y formación de hernias en los embarazos posteriores. También se han descrito deficiencias específicas de micronutrientes. Por otra parte, existen informes contradictorios sobre el efecto en el peso fetal.Conclusiones: el seguimiento de los embarazos después del primer año de la cirugía para pérdida de peso no informa episodios importantes de malnutrición materna o fetal. La evidencia muestra que los resultados del embarazo después de la cirugía bariátrica son favorables, en comparación con los resultados en los obesos no tratados quirúrgicamente, se necesitan más estudios prospectivos diseñados cuidadosamente para evaluar áreas de incertidumbre en este campo.
