Fulltext Rhinosporidiosis presenting as recurrent nasal polyps

Khoo JJ, Kumar KS

Med J Malaysia, 2003 Jun;58(2):282-5.
PMID: 14569751 MyJurnal

Rhinosporidiosis is a chronic granulomatous disease of the mucous membrane, predominantly of the nose and nasopharynx. It is uncommon in Malaysia but has been seen in immigrant workers from endemic areas like India and Sri Lanka. A case seen in Johor is reported here to highlight the need of awareness among clinicians at a time where there is increasing numbers of immigrant workers in our country. The causative organism of this disease is Rhinosporidium seeberi, which is found in stagnant waters. Sporangia and endospores of R. seeberi are seen in the granulomatous polypoidal lesions. The patients commonly present with epistaxis and nasal blockage. Complete excision is the treatment of choice for this disease. Recurrences are common despite anti-microbial treatment.
Fulltext Blended learning for reinforcing dental pharmacology in the clinical years: A qualitative analysis

OBJECTIVES: Blended learning has become the method of choice in educational institutions because of its systematic integration of traditional classroom teaching and online components. This study aims to analyze student's reflection regarding blended learning in dental pharmacology.
SUBJECTS AND METHODS: A cross-sectional study was conducted in Faculty of Dentistry, Melaka-Manipal Medical College among 3(rd) and 4(th) year BDS students. A total of 145 dental students, who consented, participate in the study. Students were divided into 14 groups. Nine online sessions followed by nine face-to-face discussions were held. Each session addressed topics related to oral lesions and orofacial pain with pharmacological applications. After each week, students were asked to reflect on blended learning. On completion of 9 weeks, reflections were collected and analyzed.
STATISTICAL ANALYSIS: Qualitative analysis was done using thematic analysis model suggested by Braun and Clarke.
RESULTS: The four main themes were identified, namely, merits of blended learning, skill in writing prescription for oral diseases, dosages of drugs, and identification of strengths and weakness. In general, the participants had a positive feedback regarding blended learning. Students felt more confident in drug selection and prescription writing. They could recollect the doses better after the online and face-to-face sessions. Most interestingly, the students reflected that they are able to identify their strength and weakness after the blended learning sessions.
CONCLUSIONS: Blended learning module was successfully implemented for reinforcing dental pharmacology. The results obtained in this study enable us to plan future comparative studies to know the effectiveness of blended learning in dental pharmacology.
Management of postintubation tracheal stenosis with bronchoscope methods-An experience from two centers

Tracheal stenosis is a common complication of endotracheal intubation or tracheostomy, resulting in significant morbidity and mortality. Bronchoscope interventions have been proposed as a safe alternative for the management of post-intubation post-intubation tracheal stenosis (PITS). Data for patients diagnosed with PITS across two hospitals, between 2021 and 2022, encompassing demographic, clinical, and procedural details were gathered from electronic medical records, and analysed. Primary outcomes centred on assessing the incidence and severity of PITS through bronchoscope examination and radiological imaging, and the efficacy of bronchoscope interventions, including stenting and the application of mitomycin C. Twelve patients were managed for PITS. Majority of patients were females (9/12) with mean age of 46.41 years. Presenting signs and symptoms were dyspnea, rhonchi and failed extubation, the mean duration of intubation/ tracheostomy is 16.41 days (range: 3-40 days). Most common comorbidity was type 2 diabetes, (5 patients, 41.6%). The lesions mean length was 3.09 cm and Cotton-Meyer Grade II and III. Prompt evaluation is crucial, in these patients. The Cotton-Meyer grade is pivotal in treatment decisions, with intubating times correlating with the severity of stenotic disease. Our case series demonstrates the increasing utility of bronchoscopy in managing these cases.
Fulltext Pathological evaluation for sterilization of routinely used prosthodontic and endodontic instruments

Kumar KV, Kiran Kumar KS, Supreetha S, Raghu KN, Veerabhadrappa AC, Deepthi S

J Int Soc Prev Community Dent, 2015 May-Jun;5(3):232-6.

In daily practice of dentistry, we use same instruments on many patients. Before use, all instruments must be cleaned, disinfected, and sterilized to prevent any contamination. Pre-cleaning and sterilization of some devices can be difficult because of their small size and complex architecture. Dental burs and endodontic files are such instruments. Dental burs come in a variety of shapes and sizes, all with highly complex and detailed surface features.
