Authors: Manohar G. Syam , Jabbar Khan Majid
Published: January 2020

Background: Chronic rhinosinusitis (CRS) is a common chronic disease, that have considerable impact on quality of life, functional and emotional impairments of affected beings. Post-surgical improvement of quality of life indicates the surgical success. Functional endoscopic sinus surgery (FESS) is the dominating surgical procedure for CRS. This study was designed to assess the symptom profile of patient before and after surgery and the complications after FESS in the post-operative period.

Methods: A total of 50 cases attending ENT outpatient department with clinical features and investigations suggestive of chronic sinusitis with infective pathology were randomly considered for this study. Cases were assessed for CRS symptoms pre and post operatively using grading symptoms.  

Results: Common major symptom was nasal obstruction (93.3%, N=28) followed by post nasal drip (83.33%, N=25), purulent nasal discharge (76.66%, N=23), facial pain/pressure (66.66%, N=20) and hyposmia (60%, N=18). None of the patients reported fever and facial congestion or fullness. Post operatively, cases with nasal obstruction (92.8%), purulent nasal discharge (86.9%), facial pain or pressure (85%), headache (81.8%), post nasal drip (84%), ear pain or fullness or pressure (92.8%) and hyposmia (61.1%) showed improvement after FESS at the end of three follow-up.

Conclusions: The most common symptom pre operatively was nasal obstruction which also responded best to FESS, along with all the other minor symptoms including headache. The results of this study confirm that FESS is an excellent method of treatment in patients with CRS refractory to medical treatment.

Authors: Narayana Mada Lakshmi , Gaur Urvashi , Chaithanya N. Reddy , Sravani Addanki Lakshmi
Published: January 2020

Abscess in the temporal and infratemporal space are very rare. They develop as a result of the extraction of infected maxillary molars. Temporal space infections or abscess can be seen in the superficial or deep temporal regions. A 27-year-old lady who had undergone extraction of 2nd mandibular molar five days ago came with complaints of painful swelling over left cheek and restricted mouth opening. On examination, an ill-defined diffuse parotid swelling was seen and treated with empirical antibiotics for which patient didn't respond. On examination, a diffuse hourglass swelling was seen extending from left parotid region to temporal region. CT scan revealed a bulky parotid gland with abscess involving parotid, masticator, infratemporal and temporal scalp region with reactive cervical lymphadenopathy on the left side. Surgical drainage of the abscess was done from the temporal space; subsequently, all other space abscess resolved. On conclusion, masseteric space infection leads to infratemporal and temporal space abscess as they communicate. Drainage of abscess from temporal space is adequate to resolve the abscess from other masticator spaces.

Published: January 2020

Cavernous haemangioma of the nose and paranasal sinuses is a rare lesion which often misdiagnosed preoperatively. It is slow growing and locally destructive due to pressure effect thus simulating the features of a malignant lesion. In this case we presented a 64-year-old gentleman whom presented with bleeding from right alveolar ridge. On examination revealed a friable mass of 2×2 cm which bled on contact mimicking malignant lesion. CT scan revealed a heterogenously enhancing soft tissue lesion with surrounding bone remodelling which made it difficult to rule out malignancy. The tissue punch biopsy suggestive of inflammatory myofibroblastic tumour, however unable to rule out low grade malignancy. With the dilemma of making an accurate preoperative diagnosis, we proceeded with right total maxillectomy as to provide a total resection of the tumour. Postoperative histopathological examination confirmed to be cavernous haemangioma. This camouflaged presentation of cavernous haemangioma was a challenge in the decision making to provide the best curative treatment. Cavernous haemangioma of maxillary sinus is a complex entity, thus diagnosing this lesion is in grey area for the surgeons. A high index of suspicion combined with the radiological finding is crucial in deciding the treatment option in such camouflaged presentations. An analytical and suspicious mind combined with histopathological and radiological examination is pertinent for confirmation of the diagnosis.

Authors: Mohanty Prabina R. , Fasal Abam
Published: January 2020

The diagnosis is suspected clinically based on microscopic otoscopy, audiometry, and tympanometry. Thin-section computed tomography of the temporal bone helps to confirm the diagnosis. This case report aimed to promote the importance of tympanometry screening as a diagnostic tool for middle ear pathology. A case of 27-year-old patient came to ENT-OPD at Al-Ameen Medical College and Hospital, Vijayapur with the complaint of decreased hearing since 2 years. The history of intermittant tinnitus and swimming habit with head bath regularly were found in the patient. Also, there were no significant family history of hearing loss, ear discharge, and ear pain. This case report concluded that the continuous head bath may leads to middle ear pathologies like otosclerosis and give importance to tympanometry test for early clinical diagnosis and suggesting for avoiding swimming, and also use of ear plugs as necessary during head bath.

Published: January 2020

Tracheobronchial foreign body aspiration is a life threatening emergency that requires prompt removal, but sometimes it may remain undetected because of atypical history, or misleading clinical and radiological findings. We present a case report of a 32 years old female who presented with progressive dyspnoea, misdiagnosed as asthma, not responding to bronchodilators and finally diagnosed as foreign body in trachea. The inclusion of foreign body aspiration in the differential for such patients allows for early recognition and appropriate management.

Published: January 2020

Surgery for the base of the tongue lesions can be challenging since this area is difficult to access and contains important neurovascular structures. External incision in the neck via an approach that varies from a transoral midline glossotomy approach to a lip-split mandibulotomy, which inevitably results in obvious scarring of the face and neck. Transoral robotic surgery can be considered for removal of these difficult neoplasms. But limitations of robotic surgery include the size and cost of the device, a learning curve, and safety concerns. Hence, alternative surgical approaches that allow for good exposure, complete tumour excision, low complication rates, low recurrence rates, and no postoperative neck scarring are preferred.

Published: January 2020

Sphenochoanal polyp is a rare entity. Isolated polyps arising from mucosa covering the anterior wall of the sphenoid sinus or sphenoethmoidal recess extending till oropharynx is extremely rare. We aim to report a rare case of sphenochoanal polyp with a slender, unusually long stalk which extended till nasopharynx leading to a large bulky polypoidal mass extending till oropharynx. Due to its posterior location, sphenochoanal polyps are often diagnosed late as they can be easily missed in clinical examination. We intend to emphasize the combined use of diagnostic nasal endoscopy and computed tomography imaging in patients presenting with unilateral or bilateral nasal obstruction, snoring and recent onset of sleep disturbances. Treatment includes endoscopic excision of polyp and cauterization of the base of the stalk. Widening of the sphenoid sinus ostium is done when necessary. Early and complete removal and regular follow up is essential to prevent complications.

Published: January 2020

Rhinolith or nasal stone is formed by mineralization within nasal cavity. They are calcareous concretions that are formed by the deposition of salts on an intranasal foreign body. It is an uncommon disease that may present asymptomatically or cause symptoms like nasal obstruction, consecutive sinusitis with or without purulent rhinitis, post nasal discharge, epistaxis, anosmia, nasal malodour and headache. They are usually diagnosed incidentally on radiographic examinations or depending on the symptoms. In this paper we report a 28-year-old woman admitted in the ENT department of GGS Medical College and Hospital, Faridkot with a calcified mass in the right nasal cavity causing long standing unilateral nasal obstruction for 3 years, rhinorrhoea (usually malodourous foetid), post nasal discharge and headache for 1 year. The calcified mass was thought to contain the air cell and removed by endonasal approach. The aim of this study is to report a case of rhinolith with chronic maxillary sinusitis along with a review of literature.
Role of bilastine in allergic rhinitis: a review
Authors: Dhingra Rachna
Published: January 2020

The prevalence of allergic diseases is increasing globally, most particularly in middle to low-income countries. Allergic rhinitis and urticaria are common allergic diseases that may have a major negative impact on patient’s quality of life. Bilastine, a novel new-generation antihistamine that is highly selective for the H1 histamine receptor, has a rapid onset and prolonged duration of action. In the fasting state bilastine is quickly absorbed, but the absorption is slowed when it is taken with food or fruit juice. Therefore, it is recommended that bilastine is taken at least one hour before and no sooner than two hours after a meal. This review article describes about the role of bilastine in allergic reactions.

Authors: Bliss Jeremy , Inja Dan Barnabas , Nithyananth Manasseh , Cherian Vinoo Mathew
Published: January 2020

Background: Reconstructive operative procedures for post-traumatic deformities of the tibial plateau have been described in literature, though rarely. We report short term follow-up of eleven such cases of primary intra-articular osteotomy.

Methods: From 2005 through 2011, a primary intra-articular osteotomy for varus malunion of the medial condyle of the tibial plateau was performed in eleven consecutive cases. The patients were assessed clinically and radiologically at a minimum of 28 months post-operatively. The functional outcome was assessed using Rasmussen score.  Paired ‘t’ test was used to determine the statistical significance.

Results: There were eleven male patients. Average follow up was 59 months (range 28 to 159). Articular congruity was restored to acceptable in all patients and varus malalignment was corrected from a mean of 1.5 degrees varus to 5.7 degrees of valgus (statistically significant, two-tailed P value of 0.0056) to an extent comparable to the normal side (mean 5.8 degrees). There were no infections. All patients had good to excellent functional outcome.

Conclusions: A primary intra-articular osteotomy and osteosynthesis for malunited medial condyle fracture of the tibial plateau would help to restore mechanical alignment and improve functional outcome.

Published: January 2020

Background: The objective of the study was to report the experience in the management of traumatic injuries of the limbs.

Methods: This was a retrospective descriptive study involving 342 patients managed in our department from January 2017 to December 2018. Study variables included epidemiology, clinical presentation and management. Open fractures were classified according to Cauchoix Duparc classification.

Results: The study population included 241 males (70, 47%) and 101 females (29, 53%). The mean age was 44, 7 years (18 and 96 years). The lower limbs were involved in 292 patients (85, 4%); the upper limb in 50 patients (14, 6%). Surgical treatment was achieved in 305 patients and orthopedic in 37 patients. The average hospital stay was 35 days for patients managed surgically and 2 months for patients managed orthpedically. A 6 years follow up revealed 9 cases of osteitis on external fixators; 4 cases of aseptic non-union and 13 cases of moderate knee stiffness.

Conclusions: Traumatic injuries of the limbs represent a major problem encountered in our daily practice. The predominance of pelvic limb fractures in most cases is due to road accidents. To prevent these issues actions should be taken such as upgrading the infrastructures and setting a health insurance system for all in order to ensure early and adequate care for all.

Published: January 2020

Background: Facial pigmentary disorders are a group of heterogenous entities, sharing a common clinical feature of altered pigmentation of the face and thus easily visible cosmetic disfigurement. Although the increased melanin provides protection from harmful effects of UV radiation, including photodamage and skin cancers, it also makes darkly pigmented skin more vulnerable to post-inflammatory dyspigmentation. The importance of these disorders is growing, as they form the major percentage of dermatology consultations. The objective of the study was to assess the clinical profile of patients with facial hyperpigmentation.

Methods: The present cross-sectional hospital based observational study was conducted at Dermatology Department of during the period of June 2017 to December 2017 including patients with diagnosis of facial hyperpigmentation. Data analysed with SPSS 24 version.

Commonly observed facial hyperpigmentation type was melasma in our study i.e. 46%. It is followed by post inflammatory hyperpigmentation (PIH) in 16% and ephilides in 8%. Rehl's melanosis and drug induced melanosis was seen in 7% each of the patients. Ephilides, Rehl's melanosis and drug induced was seen in 7% each of the patients. Family history of pigmentaory disorder was found in melasma, PIH and ephilides in our study.

Conclusions: Commonly reported age group was 20-40 with female preponderance. Commonly observed facial hyperpigmentation type was melasma (46%), PIH (16%) and ephilides (8%).
Melodie prefacji pozamszalnych w Pontificale Plocense z XII wieku
Authors: Wiśniewski Piotr
Published: January 2020

Artykuł podejmuje zagadnienie prefacji pozamszalnych w Pontificale Plocense z XII wieku (Biblioteka Seminarium Duchownego w Płocku). Autor przedstawia krótką charakterystykę księgi, przybliża początki śpiewu prefacji i próby zapisywania melodii. Omawiając prefacje pozamszalne zwraca uwagę wyłącznie na kadencje muzyczne zapisane notacją cheironomiczną i dokonuje ich komparacji z Pontyfikałem biskupów krakowskich (XI/XII w.) i Pontyfikałem wrocławskim (XII w.). Pontificale Plocense wykazuje tendencję do podziału tekstu prefacji na krótsze odcinki, co miało istotny wpływ na budowę muzyczną prefacji i dawało możliwości różnej jej interpretacji. Niewykluczone, iż recytatyw prefacji w księdze płockiej podlegał różnym stopniom melodyzacji, tzn. z większą lub mniejszą ingerencją neum złożonych. Wersje melodyczne kadencji prefacji pozamszalnych odwzorowują odmiany in tono solemnis oraz in tono solemniori. Liczne schematy kadencji in tono solemniori wskazują na dążenie do tworzenia nowych, bardziej kunsztownych wzorców melodycznych.

Pensamiento Complejo, Bases Para Una Teoria Holistica De La Educacion Superior En El Rediseño Curricular/Complex Thinking, Bases for a Holistic Theory of Higher Education in Curricular Redesign
Authors: Macías E , Uquillas G , Aquino M , Macias B
Published: January 2020

El objetivo del presente artículo, consiste en realizar una reflexión sobre la perspectiva epistemológica de la complejidad desde las perspectivas de las ciencias. En este sentido, se defiende que un enfoque holístico puede servir de ayuda activa en la enseñanza de la complejidad desde un enfoque crítico y reflexivo amparados en nuevos paradigmas. Después de la relación del pensamiento complejo y la perspectiva holística en el aprendizaje con la dimensión mente que piensa, mente que siente, y mente intuitiva en la educación, trazamos la posibilidad de configurar diseños curriculares de aprendizaje relacionalmente desde la reflexión teórica donde se destaca los nuevos contenidos y asignaturas y la teoría fundamentada en la praxis que radica, en identificar procesos sociales mediante la construcción de teoría a partir de la realidad objetiva. Terminamos formulando desde la perspectiva filosófica y desde la concepción de la realidad se desprende, metódicamente, tres tipos de formaciones profesionales integradas y simultáneas, a partir de las cuales los profesionales en formación adquieren conocimientos, valores y prácticas demostrables transversalmente, durante toda su formación.
The objective of the present article consists of the analysis of the new paradigms of the holistic education and its repercussions on higher education defined by the complexity and multidisciplinary. In this sense it is argued that a holistic approach can serve as an active help in the teaching of complexity from a critical and reflexive approach supported by new paradigms. After the relation complex thought and the holistic perspective in learning with the dimension thinking mind, feeling mind and intuitive mind in education, we design the possibility of figuring out learning curricular designs rationally from the theoretical reflection where the new contents and subject matters are outstanding as well as the theory based on the praxis which leads to identify social processes through the construction of theory from objective reality. We conclude by formulating from the philosophical perspective and the reality conception methodically three types of integrated and simultaneous professional formations from which professionals in formation acquire knowledge, cross demonstrable practices and values during all their formation.
