A Rare Presentation of Thyroid Mass- A case report.

Background-Respiratory symptoms are not uncommon in thyroid diseases and can be overlooked and misdiagnosed as acute exacerbation of asthma or COPD. Case report- A 58 years old female presented to emergency department with complaints of fever, shortness of breath from last 3-4 days for which she intubated in emergency department and shifted to ICU. Next day patient was absolutely fine and extubated and was planned to be shifted out surprisingly the same episode was repeated following which patient was intubated again and was found to be absolutely normal after 3-4 h and extubated again. The same episode was repeated next day as well. Eventually she was diagnosed to have cystic thyroid swelling. Immediate aspiration of the cyst done to relieve the symptoms and total thyroidectomy was done subsequently and patient was cured of the symptoms. Conclusion- Acute airway obstruction can occur in asymptomatic goitre patients. The anaesthetic management is crucial for airway till definitive surgery is done.

A prospective randomized study to evaluate the efficacy of pressure support ventilation with and without positive end expiratory pressure for preoxygenation in adult patients.

A primary concern for anesthesiologists is the maintenance of oxygenation during general anesthesia. Extending the safe apnea time, which is the time from the onset of apnea until the oxygen saturation concentration reaches 90% or less, increases the margin of safety with tracheal intubation. Preoxygenation before anesthetic induction has been a widely accepted manoeuver to increase oxygen reserves and hence delay the onset of arterial desaturation during apnea. This study aimed to evaluate the efficacy of pressure support ventilation with/without positive end-expiratory pressure (PEEP) for preoxygenation in adult patients. A total of 132 patients, aged 20 to 50 years, scheduled for elective surgery under general anesthesia, requiring endotracheal intubation, were included and randomly divided into three groups (n = 44 per group): spontaneous ventilation (SV), pressure support ventilation without PEEP (PS), and pressure support ventilation with PEEP (PEEP) groups. In the SV group, the patients breathed spontaneously without any support using a face mask; in the PS group, the patients breathed spontaneously with the inspiratory pressure support of 12 cm H2O without PEEP; and in the PEEP group, the patients were subjected to preoxygenation (similar to the PS group) with PEEP at 6 cm H2O. Preoxygenation was terminated when the fraction of expired oxygen reached 90% and the duration was recorded. Time from 90 seconds after administration of rocuronium bromide until oxygen saturation fell to 93% was recorded and taken as safe apnea time. The time taken for preoxygenation (the expired oxygen fraction reaches 90) was significantly shorter in patients of PEEP and PS groups when compared to the SV group. The safe apnea time was significantly longer in patients of PEEP and PS groups compared with the SV group. Application of inspiratory pressure support of 12 cm H2O and PEEP of 6 cm H2O during preoxygenation significantly reduces the preoxygenation time and prolongs the safe apnea time compared with conventional preoxygenation.

Functional and radiological outcomes of primary ring fixator versus antibiotic nail in open tibial diaphyseal fractures: A prospective study.

BACKGROUND: Management of open fractures of tibia is still a matter of debate due to high incidence of infections. Traditionally external fixators have been advocated in managing open tibial fractures. Due to limited efficacy of systemic antibiotics, recently antibiotic coated intramedullary interlocking nails have been developed for the management of open tibia fractures. Therefore, we conducted this prospective randomized study to compare the functional and radiological outcomes of primary ring fixator versus antibiotic coated nail in open diaphyseal tibial fractures. METHODS: The study included 32 patients with Gustilo-Anderson type II and type IIIA fractures of tibial diaphysis. Out of them 16 patients were managed with Ring External Fixator (Group I) and 16 were managed with OssiproÒ gentamicin intramedullary interlocking tibial nail (Group II). The radiological and functional outcomes were assessed at final follow-up according to and SMFA criteria. Statistical analysis of the data was performed using IBM SPSS statistics 2.0 software. Chi square test and independent student t-test were used and a P value <0.05 was considered statistically significant RESULTS: Union was achieved in 15 patients (93.8%) in group I and 13 patients (81.2%) in group II. Pin tract infection was seen in 6 patients (37.5%) in group I, whereas infection was present in 2 patients (12.5%) in group II. Bone results were excellent in 13 patients (81.3%), good in 2 patients (12.5%), poor in one patient (6.3%). In group II, bone results were excellent in 12 patients (75%), good in one patient (6.2%), poor in 3 patients (18.8%). At 1 year of final follow up, mean SMFA score was 24.41±5.87 in group I, whereas mean SMFA score was 23.703±8.02 in group II. CONCLUSION: Ring fixator as well as antibiotic coated tibial interlocking nail achieved comparable rates of union in the present study. Complication rates were similar in both the groups and the functional and radiological outcomes were comparable in both groups. Results of this study indicate that although ring fixation is an established option for management of open tibial fractures, antibiotic-coated intramedullary nail is also a reliable option in open Grade II and grade IIIA injuries. LEVEL OF EVIDENCE: Level II.

Staphylococcus aureus: Screening for Nasal Carriers in a Community Setting with Special Reference to MRSA.

Introduction. Emergence of MRSA infections among previously healthy persons in community settings (without exposure to health care facilities) has been noted recently. MRSA infections are now classified as health care-associated MRSA (HA-MRSA) and community-associated MRSA (CA-MRSA) infections. Its colonization is an important risk factor for subsequent MRSA infection. Aims and Objectives. The aim was to screen patients and health care workers for staphylococcal carriage, identify risk factors for MRSA colonization, and determine the sensitivity pattern. Materials and Methods. A total of 200 subjects were screened for nasal carriage after obtaining verbal consent. These were both healthy subjects attending various outpatient departments and health care workers. Specimens were collected from the anterior nares using premoistened sterile cotton swabs and inoculated onto blood agar and mannitol salt agar and incubated at 37°C for 24-48 h. Results. Staphylococcus aureus colonisation was found to be 12% (n = 24). MRSA was identified in 5% (n = 10) which represents 41.66% of SA. A total of 10 strains of MRSA were isolated from 200 subjects, giving an overall positivity rate of 5%. Discussion. Staphylococcal colonization was found to be 12% (MRSA 5%). Fluoroquinolone resistance was remarkable whereas all strains were sensitive to vancomycin, teicoplanin, linezolid, quinupristin-dalfopristin.
