RESUMEN
Bronchopulmonary carcinoid tumors are rare, slow-growing malignant neuroendocrine tumors. Early diagnosis is pivotal as surgical resection is the main stay of treatment. A 40-year-old female with typical bronchial carcinoid presented with complaints of breathlessness on mild to moderate exertion, intermittent productive cough, low-grade fever, and loss of appetite since 1 year. Right lobectomy was performed with regional lymph node resection; during resection of the tumor, manipulation led to a massive surge and fluctuations in blood pressure which were managed with deepening of the plane of anesthesia and administration of nitroglycerin infusion. She was discharged home in a good condition. Typical carcinoid tumor involves the central airways causing bronchial obstruction; however, in the present case, non-specific symptomatic presentation led to late detection. The outcome of typical carcinoids even with lymph node metastasis is excellent with complete resection; however, close follow-up is recommended due to a high incidence of recurrence.
RESUMEN
Lung hydatid cyst is a frequently encountered site of echinococcus infection after the liver. Rupture of endobronchial hydatid cyst may lead to hydatemesis or may spread to the normal lung or can cause anaphylactic reactions. Performing bronchoscopy in cases with bronchial hydatid is controversial. The thoracic hydatid cyst may destroy the native lung parenchyma or may cause mass effect on the surrounding structures. Ball valve obstruction of the bronchial hydatid cyst is not documented in the literature and here the authors present such a case as the recognition of the ball valve mechanism is important as it may cause tension pneumothorax.

RESUMEN
The study was carried out to evaluate the effect of prophylactic single-dose intravenous amiodarone in patients undergoing valve replacement surgery. Maintenance of sinus rhythm is better than maintenance of fixed ventricular rate in atrial fibrillation (AF) especially in the presence of irritable left or right atrium because of enlargement. Fifty-six patients with valvular heart disease with or without AF were randomly divided into two groups. Group I or the amiodarone group (n=28) received amiodarone (3 mg/kg in 100 ml normal saline) and group II or the control group received same volume of normal saline. The standardized protocol for cardiopulmonary bypass was maintained for all the patients. AF occurred in 7.14% patients in group I, and in group II, 28.57% (P=0.035); ventricular tachycardia/fibrillation was observed in 21.43% patients in group I and 46.43% patients in group II (P=0.089) after release of aortic clamp. Most of the patients in group I (92.86%) maintained sinus rhythm without cardioversion or defibrillation after release of aortic cross clamp (P=0.002). Defibrillation or cardio version was needed in 7.14% patients in group I and 28.57% patients in group II (P=0.078). A single prophylactic intraoperative dose of intravenous amiodarone decreased post bypass arrhythmia in this study in comparison to the control group. Single dose of intraoperative amiodarone may be used to decrease postoperative arrhythmia in open heart surgery.
