An odontogenic cutaneous sinus tract is a pathologic canal that initiates in the oral cavity but opens externally at the cutaneous surface of the face or neck. It is frequently misdiagnosed, leading to inappropriate treatment. A 44-year-old female patient referred to us with a chronically draining lesion on his chin. The lesion previously was misdiagnosed by medical doctors and had undergone cryotherapy and surgery with a focus on the skin lesion and had received antibiotic therapy for a prolonged period of time. After clinical and radiologic examination the dental origin of the lesion was evident and proper endodontic treatment was performed followed by surgical treatment after the recurrence of pus discharge 2 weeks after the conventionnel root canal treatment. Five months later, after the treatment, the lesion showed an obvious healing. After 18 months, the patient was comfortable and a significant healing of the sinus tract was noted, the periapical radiograph shows clear regression of the periapical lesion and an improvement in bone trabeculation. The key to successful treatment of cutaneous sinus tract of dental origin must be appropriate communication between the dentist and the physician in order to achieve correct diagnosis and therapy in such cases.

COVID-19 pandemic had caused an unprecedented impact on teachers and students in their teaching and learning process. Diverse teaching and learning tools are essential to ensure that education continues. This confinement provides an opportunity to enculture a new norm for learning among Malaysian students and teachers. Usage of web 2.0 tools has indirectly encouraged students to study on their own and communicate dynamically with peers and teachers during online lessons. A mixed-method quasi-experimental study involving pre-test and post-test was conducted to investigate the impact of using web 2.0 tools on students’ achievement. 60 Form Two students were divided into control and experimental groups where the experimental group had lessons using The Product, Process, Person, and Press model of creative approach with web 2.0 tools while the control group was taught using the teacher-centered instruction. The creative approach using web 2.0 tools has not only produced advancement in students’ achievement in the science subject but has also motivated them to complete the assessments given during online lessons. The findings also emanated that students’ motivation to learn science through online learning was due to the usage of 2.0 tools. Hence, science teachers ought to be better prepared with the skills as well as better-designed learning modules and experiences to incorporate integrated online learning and face-to-face class with a blended learning approach seamlessly.

Synovial sarcoma is a soft tissue sarcoma. Its occurrence as a primary mediastinal neoplasm is very rare. We report a case of mediastinal synovial sarcoma in a 14-year-old girl with exertive dyspnoea at presentation. On physical examination, there was a superior vena cava syndrome and caféau-lait spots. Chest X-ray revealed a white left hemithorax with mediastinal deviation to the opposite side. Thoraco-abdomino-pelvic scanner showed a voluminous posterior cervico-mediastinal tissue mass. Computed tomography (CT)-guided biopsy of the mediastino-pleural mass was performed. Histological examination reported fusocellular malignant mesenchymal proliferation. A complementary immunohistological study with a broad range of antibodies was performed with a high-grade single-phase spindle cell synovial sarcoma of the mediastinum. She presented a respiratory distress, did not respond to resuscitation, and died. Mediastinal synovial sarcoma is a rare tumour that is difficult to diagnose. Its slow progression and delay in diagnosis may lead to a fatal evolution.
