Unmanned air vehicles (UAV) have been used for many years and it mainly focus on military purposes. Numerous UAV development have been popular worldwide because the low in development cost, operating cost and ability to provide accurate surveillance information and it is a better option for performing reconnaissance missions in hostile environment. However, in the past years a new type of UAV has appeared that possessed lighter weight and smaller in size and it is categorized as a micro unmanned air vehicle (μ-UAV). Although the non-autonomous ready-to-fly tailless μ-UAV exists among local universities, the development of non-autonomous ready-to-fly tailless μ-UAV is still open to be explored. Thus, this project demonstrates the development of the non-autonomous ready-to-fly tailless μ-UAV named as Neo-Ptero. A special CNC hot wire cutter machine was used in the Neo-Ptero fuselage and wing development in which has evidently produced high accuracy of shapes and geometry based on the CAD design. A 3D printing process was used to produce few parts in the Neo-Ptero μ-UAV model. The model was equipped with on shelves RC components for future flight testing purpose. The actual Neo-Ptero weigh around 1.3kg and has a wingspan of 120.6cm.
Warthin's tumor, also known as adenolymphoma or papillary cystadenoma lymphomatosum, is a benign tumor almost exclusively found in the parotid gland and is the second most common type of benign parotid tumor. Its manifestation as an extraparotid lesion is rare, with a low incidence in the submandibular gland. In this context, we present a case of Warthin's tumor of the submandibular gland in a 66-year-old man who presented with a painless lateral cystic cervical mass. This case highlights the clinical and radiological evidence of an uncommon extraparotid tumor location, with the diagnosis becoming evident only after the enucleation of the mass. Despite the rarity of extraparotid Warthin's tumor and its potential variation in location, the authors recommend considering Warthin's tumor of the submandibular gland in the differential when assessing lateral cervical masses.
Tuberculosis is a highly contagious granulomatous disease which is endemic in South East Asia. Most common presentation is pulmonary tuberculosis which is spread by droplets inhalation of mycobacterium tuberculosis bacterium. Nasopharyngeal tuberculosis is a rare entity which poses a diagnostic difficulty as its presentation is greatly similar to that of nasopharyngeal carcinoma. Herein, we describe two cases of nasopharyngeal tuberculosis which mimics nasopharyngeal malignancy leading to diagnostic difficulties.
A retrospective case series was conducted to determine the clinical characteristics and bronchoscopy findings of children with foreign body aspiration in Paediatric Institute, Hospital Kuala Lumpur. Ten boys and two girls were included (range 2-177 months; median 26 months old). They commonly presented with cough (12/100%) and difficulty in breathing (9/75%). All patients had unilateral auscultatory findings and the commonest radiographic findings were unilateral hyperinflation (7/58.3%). The majority of foreign bodies removed was organic (8/66.6%) and more frequently found in the left bronchial tree (7/58.3%). Major complications were pneumonia (11/91.6%) and airway oedema (11/ 91.6%). Eight patients had delayed diagnosis due to parents unawareness (6/50%) and missed diagnosis (2/16.7%).
