Eyelid fat grafting: indications, operative technique and complications; a systematic review

International audienceIntroduction - Many recent studies concerning autologous fat grafting in the eyelids have been published, mostly consisting of case reports and retrospective case series. However, no study on the overall complication or satisfaction rate associated with the various grafting techniques exists. We performed a comprehensive literature review to determine the outcomes and complications of eyelid fat grafting, as well as patient satisfaction.Methods - A systematic review of the literature using the PRISMA criteria was conducted. This protocol was registered at the Prospective Register of Systematic Reviews at the National Institute for Health Research.Results - Sixteen studies, representing 1,159 patients and published between June 2004 and December 2014, were included. Satisfactory results, judged by clinical examination, were observed in all studies. Few postoperative complications were reported.Conclusions - We demonstrated that the procedures were easy to perform, and achieved satisfactory and sustainable results with few complications in both reconstructive and cosmetic surgery. However, a wide disparity exists in the various fat harvesting, fat purification, and reinjection techniques. Further studies are required to assess the long-term outcomes. Our conclusions should be accepted cautiously due to the small number of articles and the lack of evidence in published studies.<br

Thyroid Cancer Risk Factors and Early Detection Awareness among Umm Al-Qura University Medical Students

Background: Thyroid carcinoma (TC) is the most prevalent head and neck cancer. Pre-clinical students lacked essential knowledge of thyroid cancer. Furthermore, clinical years medical students needed more awareness of thyroid screening and self-examination. Consequently, this study aims to identify the knowledge and understanding of thyroid cancer, among Umm Al-Qura University medical students in Saudi Arabia. Methods: A cross-sectional study was conducted on undergraduate medical students in the third to sixth year of a medical college using an online questionnaire from April to June 2022. Results: A survey of 297 medical students from the 3rd to 6th year found that 46.1% knew all early signs of thyroid cancer, while only 12.5% did not know any diagnostic tools. Most participants (74.4%) knew all desirable candidates for a thyroid cancer screen. 260 (87.5%) students answered positively that any unexplained lump or swelling could be an early sign of cancer. The gender of the participants had a significant correlation with many factors related to student knowledge of thyroid cancer, with gender having a substantial correlation with only two early signs. The student's grade point average (GPA) and academic year also had a significant correlation with many factors related to thyroid cancer knowledge. Conclusion: Thyroid cancer prevalence can be reduced by increasing public awareness and knowledge of risk factors. Students’ knowledge and participation in public education can lead to better results. In addition, increased public awareness about early signs of thyroid cancer can improve overall disease prognosis, morbidity, and mortality

Effect of parathyroidectomy on quality of life and non-specific symptoms in normocalcaemic primary hyperparathyroidism

International audienceBACKGROUND: Normocalcaemic primary hyperparathyroidism (NcPHPT) is a new clinical entity being diagnosed increasingly among patients with mild primary hyperparathyroidism (PHPT). The aim of this study was to evaluate quality of life and non-specific symptoms before and after parathyroidectomy in patients with NcPHPT compared with those with hypercalcaemic mild PHPT (Hc-m-PHPT).METHODS: This was a prospective multicentre study of patients with mild PHPT from four university hospitals. Patients were evaluated before operation, and 3, 6 and 12 months after surgery for quality of life using the SF-36-v2® questionnaire, as well as for 25 non-specific symptoms.RESULTS: Before operation, the only statistically significant difference between the NcPHPT and Hc-m-PHPT groups was in the mean(s.d.) blood calcium level (2·54 versus 2·73 mmol; P &lt; 0·001). At 1 year after surgery, the blood calcium level had improved significantly in both groups, with no significant difference between them. Quality of life improved significantly in each group compared with its preoperative score, with regard to the physical component summary (P = 0·040 and P = 0·016 respectively), whereas the mental component summary improved significantly in the Hc-m-PHPT group only (P = 0·043). Only two non-specific symptoms improved significantly in the NcPHPT group compared with nine in the Hc-m-PHPT group.CONCLUSION: Parathyroidectomy mildly improves quality of life and some non-specific symptoms in patients with NcPHPT.</p

Mild sporadic primary hyperparathyroidism: high rate of multiglandular disease is associated with lower surgical cure rate

International audienceBACKGROUND:Mild primary hyperparathyroidism (serum calcium ≤ 2.85 mmol/L) is the most representative form of pHPT nowadays. The aim of this study was to evaluate its subtypes and the multiglandular disease (MGD) rate as it may lower the sensitivity of preoperative parathyroid scintigraphy and the surgical cure rate.METHODS:We retrospectively included patients with mild pHPT who underwent parathyroid dual-tracer scintigraphy with 99mTc-MIBI SPECT/CT and surgery between January 2013 and December 2015. Cure was defined as normalization of serum calcium (or PTH in the normocalcemic form) at 6 months. MGD was defined by either two abnormal resected glands or persistent disease after resection of at least one abnormal gland.RESULTS:We included 121 patients. Median preoperative serum calcium was 2.68 mmol/L and median PTH was 83.4 pg/mL. A total of 141 glands were resected (95 adenomas, 33 hyperplasias). The subtypes were 57% classic, 32.2% normohormonal, and 10.7% normocalcemic. MGD occurred in 23.5% of patients divided as 13%, 30%, and 64% respectively (p = 0.0011). The surgical cure rate was 85.2%. The normocalcemic form had lower cure rate than the normohormonal (45% vs 84%, p = 0.018) and classic forms (45% vs 93%, p = 0.0006). MIBI scintigraphy identified at least one abnormal lesion, later confirmed by the pathologist in 90/98 patients, making the sensitivity per patient 91.8% (95% CI 84.1-96.2%).CONCLUSIONS:MGD is strongly associated with mild pHPT, especially the normocalcemic form where it accounts for 64% of cases. Bilateral neck exploration should be performed in this population to improve the cure rate, even if the scintigraphy shows a single focus

The locoregional recurrence post-mastectomy for ductal carcinoma in situ: Incidence and risk factors

International audienceBACKGROUND: The objective of this retrospective study was to determine the incidence of recurrence of breast cancer after mastectomy for ductal carcinoma in situ (DCIS) in our institution, and to evaluate the associated risk factors while comparing them to those proposed in the literature. METHODS: The files of 218 patients who had undergone mastectomy for pure DCIS or DCIS with micro-invasion at Centre Eugène Marquis between January 2003 and November 2013 were compared for: age at diagnosis, type of mastectomy and immediate reconstruction, tumor characteristics, and the evaluation of the sentinel axillary lymph node. The mean follow-up period was 30.5 months. RESULTS: In a mean period of 39.13 months, 8 patients (3.67%) developed a recurrence post-mastectomy, 2 of whom with distant metastasis. Two others developed distant metastases subsequently during treatment. All 4 died due to progression of metastases, while the other 4 are alive and disease-free after treatment. The only risk factor was young age at initial diagnosis (\textless40 years). None of the other factors described in the literature, such as high grade or diffuse disease, comedo-necrosis, positive margins or micro-invasion were statistically significant. CONCLUSION: The recurrence of breast cancer after mastectomy for DCIS is rare, however, it carries a high mortality rate for those who do relapse. Patients who have high risk factors such as young age at diagnosis and high risk tumor factors should be followed closely for signs of recurrence and/or metastasi
