Radioguided parathyroidectomy in forearm graft for recurrent hyperparathyroidism
No full textWe report a peculiar case of recurrent hyperparathyroidism caused by hyperplasia of a forearm graft implanted following a total parathyroidectomy in a 38-year-old patient with chronic renal failure. The forearm graft hyperplasia was detected using (99)Tc(m)-sestamibi scanning, which identified hyperplastic transplanted parathyroid tissue in the forearm of the patient. During the initial surgery, the surgeon failed to mark the parathyroid tissue with sutures or clips to facilitate locating it. Therefore, we referred the patient for radioguided surgery. This surgical procedure allowed us to locate and completely remove the hyperfunctioning transplanted parathyroid tissue
Extremely Late Recovery of Unusual Cervical Ankylosing Spondylitis-Related Dysphagia: Anesthesiologic, Surgical, and Pathophysiological Considerations, and Review of the Literature
No full textBACKGROUND: Ankylosing spondylitis (AS) is an inflammatory disease that involves above all the spine and the pelvis. In the spine, the inflammatory processes cause the formation of syndesmophytes between the vertebral bodies and the ossification of ligaments, with bony overgrowth. In this setting, dysphagia is a rare but severe complication and only a few cases have been reported in the literature.CASE DESCRIPTION: We describe the case of a 50-year-old man suffering from AS, with a 6-month history of severe dysphagia caused by bone compression of the esophagus at the C3-5 level. Because the patient underwent a 10-kg weight loss 2 months after clinical onset, a gastrostomy tube placement was needed. Complete surgical excision of the bone overgrowth via an anterior cervical approach was performed, but despite continuous intensive swallowing rehabilitation therapy, the patient failed to improve in the first following months. Surprisingly, the patient started to improve 18 months after the operation, with a complete recovery from dysphagia 24 months after.CONCLUSIONS: Among the 5 reports (including the present case) available in the current literature with a clear dysphagia recovery follow-up, the present case (the second one harboring gastrostomy) is associated with the slowest complete recovery published so far. This unusually late recovery suggests a possible role not only of the mechanical decompression of the esophagus but also of the degeneration/regeneration ratio of the myenteric plexus, along with local neurotransmitters sensitivity changes, to better understand the dysphagia recovery time course of this unique patient
Diagnostic and Prognostic Role of HBME-1, Galectin-3, and β-Catenin in Poorly Differentiated and Anaplastic Thyroid Carcinomas.
No full textAIM:: Thyroid cancer represents the first endocrine malignant neoplasm, accounting for 1% of human malignancy. The majority of which are well-differentiated cancer representing up to 90% of thyroid cancer and pursuing a favorable clinical course. The groups of poorly differentiated thyroid cancer (PDC) and anaplastic thyroid cancer (ATC) have a poor outcome and need a strict clinical surveillance. MATERIALS AND METHODS:: Thirty-four cases including 23 PDC/insular cancer and 9 ATC were examined for the expression of an immunohistochemical panel made up by HBME-1, galectin-3, and β-catenin and correlated either with histologic prognostic parameters or the overall surveillance. RESULTS:: HBME-1 and galectin-3 were expressed in 100% of the PDC/insular cases and in none of the ATC cases. The data for β-catenin pointed out an 80% expression (12/15) in the PDCs and only a focal and nonspecific positivity in the ATCs. A β-catenin-positive expression was found in all patients with a worse outcome/death and in the presence of vascular invasion and metastatic disease. All 3 PDC patients with β-catenin negativity are alive, whereas only 41% (5/12) are alive in the β-catenin-positive group. CONCLUSIONS:: Our data set up the idea that PDC represents an intermediate step in the biological process of dedifferentiation of thyroid tumors toward ATC. This shift is underlined by the β-catenin expression, which seems to be related to a worse prognostic behavior. HBME-1 and galectin-3 show a similar pattern in PDC compared with well-differentiated carcinoma, whereas they are not expressed, as well as β-catenin, in anaplastic carcinomas

Prospective evaluation of total thyroidectomy versus ipsilateral versus bilateral central neck dissection in patients with clinically node-negative papillary thyroid carcinoma.
No full textBACKGROUND: Prophylactic central neck dissection (PCND) for papillary thyroid carcinoma (PTC) is controversial. We compared 3 different approaches to the management of central compartment nodes in patients with clinically unifocal and N0 PTC.
METHODS: A total of 186 patients were prospectively assigned to one of the following procedures: total thyroidectomy (TT), TT plus ipsilateral PCND (Ipsi-PCND), and TT plus bilateral PCND (Bil-PCND).
RESULTS: No difference was found concerning demographic, clinical or pathologic characteristics (P = NS). More patients in the Bil-PCND group had transient hypocalcemia (P < .001). One patient in the Bil-PCND group experienced permanent hypoparathyroidism (P = NS). One transient and one permanent unilateral laryngeal nerve palsy occurred in the Ipsi-PCND group (P = NS). Significantly more patients in the Bil-PCND and Ipsi-PCND groups had node metastases recognized (26 vs 18 vs 6; P < .001). Six of 26 pN1 patients (23%) in the Bil-PCND group had bilateral metastases. No difference was found concerning mean postoperative basal and stimulated thyroglobulin and mean postoperative radioiodine uptake. One patient in the Ipsi-PCND group experienced recurrent disease (P = NS).
CONCLUSION: TT seems adequate treatment for most patients with clinically N0 PTC. PCND could be considered for a more accurate staging. Ipsi-PCND could be a valid option, but it includes the risk of overlooking contralateral metastases
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
