The challenge of pulmonary endobronchial chondromatous hamartomas.

Pulmonary chondromatous (or chondroid) hamartomas are common benign tumours of the lung and may be either parenchymal or endobronchial. The latter are only rarely encountered and have a variation in their clinical presentation related to the endobronchial obstructive lesion, including atelectasis, pneumonia, hemoptysis. If not diagnosed early and treated properly, endobronchial hamartomas can cause irreversible lung damage. We present a review of the recent English literature over the diagnostic approach and management of pulmonary endobronchial chondromatous hamartomas.

Mid-term results following surgical treatment of congenital cardiac malformations in adults.

The long term consequences of untreated of residual or recurrent lesions pose unique challenges in the growing population of adults with congenitally malformed hearts. In our unit, 335 patients aged from 18 to 72 years, with a mean age of 35 plus or minus 14 years, presented for correction of congenital cardiac disease from September, 1997, through December, 2006. Of the group, 42 (12.5%) had undergone one or more prior surgical procedures, 3 were admitted as emergencies, and a further 10 (3%) had suffered prior cardiac related complications. Symptoms had been noted by 181 patients (54%), and 42 (12.5%) had an established arrhythmia. Chromosomal anomalies were identified in 13 (3.8%), and diagnostic catheterisation was required in 201 (60%) patients. Of the overall group, 2 patients died early (0.6%). Complications occurred in 61 patients (18%), including atrial fibrillation, pneumothorax, postoperative haemorrhage, pericardial or pleural effusions requiring drainage, stroke, complete heart block, endocarditis, wound dehiscence, and peripheral neuropathy. The median length of stay in the intensive care unit and hospital were 2 and 7 days, respectively. Death occurred later in 2 further patients (0.6%), due to atrial fibrillation and pulmonary hypertension. At mean follow-up of 63 plus or minus 30 months, the majority of the remaining patients are well with resolution or significant improvement in their symptoms. Despite the long term deleterious effects of untreated, residual or recurrent congenital cardiac lesions in adults, therefore, we conclude that surgical correction can be achieved with low mortality and acceptable morbidity. Most significant complications are related to arrhythmias.

Characteristics of ascitic fluid in cardiac ascites.

OBJECTIVE: Cardiac ascites remains a rare entity with unique clinical and pathogenetic features that are not adequately recognized by clinicians. The purpose of this study was to contribute towards elucidating the nature of cardiac ascites. MATERIAL AND METHODS: We describe a series of 26 ascitic fluid samples from eight patients with cardiac ascites that were referred and further evaluated for the etiology and nature of their ascites. RESULTS: In all samples ascitic fluid was an exudate with an increased serum-ascitic fluid albumin gradient, a pattern unique in ascites. Other causes of ascites were excluded, often through a protracted differential diagnostic procedure. CONCLUSIONS: The unique pattern of cardiac ascites should allow for rapid diagnosis and characterization: The clinical implications of furosemide use in its response and biochemical properties warrant further description.

Echocardiographic evidence of posteromedial hypokinesis of the left ventricle in relation to mitral regurgitation in cardiac sarcoidosis.

We describe herein the case of a 49-year-old female patient with pulmonary sarcoidosis (stage II) with cardiac manifestation. This consisted of systolic dysfunction without dilatation of the left ventricle and severe mitral insufficiency, possibly due to thinning of the posteromedial left ventricular free wall, based on our echocardiographic observations.

Incidental parathyroidectomy during thyroid surgery: an underappreciated complication of thyroidectomy.

The aim of this study was to investigate the incidence, risk factors, and clinical relevance of incidental parathyroidectomy during thyroid surgery. Prospective analysis of data in patients following thyroidectomy, specifically regarding the presence of parathyroid parenchyma in the thyroidectomy specimens, the underlying thyroid pathology, and the presence of postoperative hypocalcemia (biochemical/clinical). The clinical records of 158 patients who underwent thyroid surgery during a 2-year period were reviewed. Pathology reports were carefully reviewed for the nature of the underlying thyroid disease, the presence, number, and size of incidentally resected parathyroid gland(s), their location, and possible parathyroid pathology. Serum calcium levels were measured preoperatively, on the day of surgery, and on postoperative days 1, 2, and 7 or even later as needed. Two groups of patients were studied: a group with incidental parathyroidectomy following thyroidectomy (group A) and a group without incidental parathyroidectomy after thyroidectomy (group B). Total/near-total thyroidectomy was the procedure of choice and was performed in 154 patients; total lobectomy and contralateral subtotal lobectomy was performed in the other 4 patients. Elective central neck lymph node dissection was performed in four patients with neck lymphadenopathy. Inadvertently removed parathyroid tissue was found in 28 cases (17.7 %); in 6 of these patients (21%) the parathyroid tissue was intrathyroidal. The percentage of women in group A was significantly higher than in group B (93% vs. 58.5%, P = 0.0002). There was no statistically significant difference between the two groups (A and B) regarding the preoperative (presumed) diagnosis, the histologic diagnosis of thyroid disease (benign versus malignant), the type/extent of surgery, or the presence of thyroiditis. Biochemical and clinical hypocalcemia was observed in 6 (21%) and 2 (7%) patients in group A, respectively, and in 30 (23%) and 8 (6%) patients of group B, respectively. There was no statistically significant difference regarding the occurrence of postoperative hypocalcemia (clinical/biochemical) between the two groups (P = 0.33). Incidental parathyroidectomy is not uncommon following thyroidectomy and in a significant percentage of cases it may be due to the intrathyroidal location of the parathyroid glands. Incidental parathyroidectomy was not found to be associated with postoperative hypocalcemia (biochemical/clinical). Incidental parathyroidectomy may be considered as a potentially preventable but clinically minor complication of thyroid surgery.

A prospective randomized trial comparing the safety and efficacy of three commercially available closure devices (Angioseal, Vasoseal and Duett).

PURPOSE: We compared the safety and efficacy of three closure devices (Angioseal, Vasoseal and Duett) used to close arterial puncture sites in patients who underwent coronary percutaneous procedures. METHODS: A prospective randomized, single-center trial was carried out of consecutive patients who underwent coronary angiography [705 patients: Angioseal (243),Vasoseal (228) and Duett (234)] or angioplasty [146 patients:Angioseal (47), Vasoseal (52) and Duett (47)]. RESULTS: In the angiography patients the device deployment rates were similar, with the Angioseal been significantly slower in achieving hemostasis (p = 0.0001) but resulting in earlier ambulation (p = 0.0001). In the coronary angioplasty patients the deployment rates were similar to those for angiography: time to hemostasis was longer for the Angioseal (p = 0.003), while ambulation times were not different, although prolonged compared with angiography (p = 0.0001). The three devices had similar major complication rates. The Vasoseal had a higher major complication rate after angioplasty than after angiography (p = 0.004). The incidence rate of peripheral embolization was lower when the Angioseal was utilized. Severe complications were mainly seen in patients who received abciximab. CONCLUSIONS: The three closure devices had high rates of successful deployment and were relatively safe. The Angioseal resulted in earlier ambulation after angiography. Utilization of closure devices after abciximab administration possibly increased the complications.
