Fluctuation of Corrected Serum Calcium Levels Following Partial and Total Thyroidectomy

Objectives: To identify any fluctuation of corrected serum calcium levels and to determine the presence of sub-clinical hypocalcaemia following partial and total thyroidectomy with preservation of at least two parathyroid glands. Design: A prospective study. Setting: Tertiary Head & Neck referral unit. Patients: Eighty five patients undergoing partial or total thyroidectomy with or without laryngectomy from April 2003 to April 2009 were included in the study. Corrected serum calcium levels (CCSL) were noted preoperatively and postoperatively on day 1, day 7 and 6 months. results: Forty six patients underwent hemi-thyroidectomy (HT), 29 underwent total thyroidectomy (TT) and 10 underwent total thyroidectomy with laryngectomy (TTL). Nine (19.56%) patients in the HT group, 6 (24.14%) in the TT group and 3 (30.0%) in the TTL group developed hypocalcaemia postoperatively which was most significant on 1st postoperative day. This improved by 7th postoperative day in each group when the change in calcium levels became statistically insignificant. Six patients (3 patients had HT, 2 had TT and 1 had TTL) developed sub-clinical mild hypocalcaemia which was persistent at 6 months follow-up. Conclusion: The most significant changes in corrected serum calcium levels occur within first 24 hours after thyroid surgery. Thereafter most patients return to normocalcaemia within a seven-day period. Despite preservation of parathyroid glands there is a subgroup of patients who develop sub-clinical hypocalcaemia which persists even at six months but does not require treatment.

原发进展性失语症患者词汇提取困难的反常表现

Impaired word retrieval is a main symptom of primary progressive aphasia (PPA) . The cognitive features of this impairment in PPA are poorly understood. We stu died 12 patients with PPA(6 English-speaking and 6 Dutch-speak- ing), 7 patients with early-stage clinically probable Alzheimer’s disease (P rAD), 5 patients with mild cognitive impairment (MCI), and 15 age matched,cognit ively intact, control subjects. Subjects had to name a picture (the probe), whic h was preceded by a written word (the prime) that could be the correct name of t he picture,a noun belonging to the same semantic subcategory (related prime), a semantically unrelated noun (unrelated prime), or a pseudoword (neutral control) . Naming latencies were longer in PPA and prad.patients than in control subjects . Critically, the interaction between group and prime type was highly significan t. PPA patients named the probe more slowly after a related compared with an unr elated prime. In contrast, prad.patients,mild cognitive impairment patients, and healthy control subjects tended to name the probe faster when it was preceded b y a related prime. The semantic interference effect in PPA generalized across la nguages and PPA subtypes. Selection among competing word forms sharing a same se mantic field is abnormal in PPA. The semantic interference effect constitutes ap ositive distinguishing feature between PPA and prad.
