A large unilocular mucinous cystadenoma in third trimester of pregnancy

Ovarian malignancy is the second most common gynaecological malignancy diagnosed during pregnancy. A grand multipara, aged 30 years presented with gestational amenorrhea with abdominal discomfort and breathlessness for last 15 days. Sonographic examination demonstrated a huge, unilocular ovarian cyst and an alive fetus of about 30 weeks gestation. Intraoperative findings were huge left ovarian cyst (42x40x20 cm) with straw coloured mucinous fluid. Left salpingo-oophorectomy was performed followed by peritoneal washings and omental biopsy. Histopathology revealed mucinous cystadenomas with inflammatory changes in omentum and no malignant cells in peritoneal washings. She delivered vaginally a female baby of 3.5 kg at 38 weeks with good Apgar score.     

An outbreak of Burkholderia cepacia associated with contamination of albuterol and nasal spray

BACKGROUND: Species within the Burkholderia cepacia complex (Bcc) can contaminate medications and disinfectants and cause severe pneumonia in critically ill patients or persons with cystic fibrosis. In March 2004, we investigated a hospital outbreak of Bcc possibly associated with a contaminated nasal spray. METHODS: We conducted a matched case-control study, environmental sampling, and observations of infection control practices. Case patients had infection or colonization with Bcc, and control patients had sputum culture not yielding Bcc. Isolates from patients and environmental samples were compared by pulsed-field gel electrophoresis (PFGE). RESULTS: Bcc was recovered from sputum in 18 patients. Compared with matched control patients (n = 18), case patients were more likely to be receiving mechanical ventilation (p = 0.01), to have been hospitalized > 6 days (p = 0.01), and to have received antimicrobial treatment within 7 days before sputum collection (p = 0.03). Bcc was cultured from opened, but not unopened, multidose albuterol bottles, a nebulizer attached to a ventilator, and opened and unopened nasal spray bottles from contaminated lots. PFGE showed that isolates from albuterol samples and from patients were indistinguishable but unrelated to the nasal spray strain. Observations revealed improper aseptic techniques during respiratory therapy procedures and inadequate nebulizer cleaning. CONCLUSIONS: Despite a temporal association with use of a contaminated nasal spray, this outbreak was caused by extrinsic contamination of multidose albuterol used for nebulization treatments and lack of adherence to infection control precautions. Implementation and re-enforcement of infection control measures successfully terminated the outbreak.     

Antioxidant constituents from Cotoneaster racemiflora

A new lignan rhamnoside, racemiside (1), has been isolated from the ethyl acetate-soluble fraction of Cotoneaster racemiflora, along with scopoletin (2), 7,8-dimethoxy-6-hydroxycoumarin (3), 3,3′,4′-tri-O-methylellagic acid (4), and cereotagloperoxide (5), reported for the first time from this species. All of them showed profound antioxidative activities in the DPPH assay.     

Gross tracheal deviation: airway challenges and concerns--two case reports

Practical guidelines and algorithms may not always help in difficult airway management. Large thyroid swellings may be responsible for several difficulties during the perioperative period, such as distortion of the airway, endocrine disturbances and metabolic effects. We here discuss the airway management of two patients with huge thyroid enlargement and gross tracheal deviation. One of those patients had also retrosternal extension of goiter. Both patients were scheduled for an excision of their colloid goiter.
