Management of cardiorespiratory function of rabbits by a customized chest drain: An experimental study.

OBJECTIVE: This study aimed to salvage the study population from the fatality that occurs due to iatrogenic injury to the thoracic cavity's pleural membrane. MATERIALS AND METHODS: An experimental study of temporomandibular joint arthroplasty with costochondral graft was carried out on 72 healthy 'Oryctolagus cuniculus' species of male rabbits. The rabbits were distributed into two age groups: growing (3-4 months) and adult (12-18 months). All the procedures were carried out under general anesthesia with xylazine hydrochloride and ketamine hydrochloride after calculating the doses, maintained by halothane and O2 inhalations. Out of 72 rabbits, 33 rabbits had accidental perforation of the pleural membrane observed that required a chest drain. RESULTS: In this study, 21 (63.64%) rabbits received chest drain and salvaged. The rest of the rabbits (n = 12; 36.36%) that did not receive any chest drain and died. Most of the rabbits (n = 17; 81%) were under the growing group, weighing less than 2 kg and four (19%) were adult rabbits. CONCLUSION: This manual chest drain is life-saving for rabbits. It is a new addition to the advancement of thoracic surgery on animals. It is cost-effective and safe. The developed customized drainage system may make it easier to harvest the costochondral graft-related experiments.

Global Burden of Head and Neck Cancer.

Head and neck cancer is increasing globally owing to rising rates of tobacco use and human papillomavirus infection. Today, cancer is the leading cause of death and disabilities in developed countries and the second leading cause of death in countries with developing economies. Understanding the global landscape of head and neck cancer will empower oral and maxillofacial surgeons to play a critical role among patients and societal education regarding the importance of addressing modifiable risk factors and continuing to play an important role in the diagnosis and management of head and neck cancer.

Effectiveness of Preoperative Lymphoscintigraphy for the Detection of Cervical Lymph Node Metastasis in Patients with Oral Squamous Cell Carcinoma.

BACKGROUND: Oral squamous cell carcinoma (OSCC) is one of the most common malignant tumor. OSCC is the malignancy of squamous epithelium of oral cavity, which is the sixth most common malignancy reported worldwide and one with highest mortality rate among all malignancies. AIMS: The aims of this study is to assess the diagnostic performance of lymphoscintigraphy (LSG) for the detection of cervical lymph node metastasis in patients with OSCC. MATERIALS AND METHODS: This was a prospective study done in Oral and Maxillofacial Surgery Department and National Institute of Nuclear Medicine and Allied Science, Bangabandhu Sheikh Mujib Medical University during July 2015-June 2016. Thirty-six patients with OSCC were included in this study. Radioisotope technique was used in the detection of cervical metastases in patients with histologically proven OSCC. Patients were assessed by LSG after diagnosis of OSCC, and then, it was compared with postoperative histopathology report. RESULTS: Lymphoscintigraphically out of 36 patients, 23 had lymphatic channel obstruction where histologically 20 patients had lymph node metastasis. There were 20 true positive cases, 13 true negative cases, and 3 false positive cases but no false negative case was found. The test of validity result reveals that sensitivity 100.0%, specificity 81.25%, accuracy 96.66%, positive predictive value 86.96%, and negative predictive value 100.0%. CONCLUSION: LSG for the detection of cervical lymph node metastasis has an important role for the management of OSCC. It is also cost-effective and decreases the morbidity.
