Online ahead of print. ABSTRACT BACKGROUND: Cinematic Rendering (CR) is a recently introduced post-processing three-dimensional (3D) visualization imaging tool. The aim of this study was to assess its clinical value in the preoperative planning of deep inferior epigastric artery perforator (DIEP) or muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flaps, and to compare it with maximum intensity projection (MIP) images. The study presents the first application of CR for perforator mapping prior to autologous breast reconstruction. METHODS: Two senior surgeons independently analyzed CR and MIP images based on computed tomography angiography (CTA) datasets of 20 patients in terms of vascular pedicle characteristics, the possibility to harvest a DIEP or MS-TRAM flap, and the side of the flap harvest. We calculated inter- and intra-observer agreement in order to examine the accordance of both image techniques. RESULTS: We observed a good inter- and intra-observer agreement concerning the type of flap and the side of the flap harvest. However, the agreement on the pedicle characteristics varies depending on the considered variable. Both investigators identified a significantly higher number of perforators with MIP compared with CR (observer 1, p<0.0001 and observer 2, p<0.0385). CONCLUSION: The current study serves as an explorative study, showing first experiences with CR in abdominal-based autologous breast reconstruction. In addition to MIP images, CR might improve the surgeon's understanding of the individual's anatomy. Future studies are required to compare CR with other 3D visualization tools and its possible effects on operative parameters. PMID:34756655 | DOI:10.1016/j.bjps.2021.09.011 View on the web Inoreader.

Improvement of Pulmonary Function in Arthrogryposis Multiplex Congenita Patients Undergoing Posterior Spinal Fusion Surgery for Concomitant Scoliosis: A Minimum of 3-Year Follow-up

xlomafota13 shared this article with you from Inoreader Improvement of Pulmonary Function in Arthrogryposis Multiplex Congenita Patients Undergoing Posterior Spinal Fusion Surgery for Concomitant Scoliosis: A Minimum of 3-Year Follow-up Via leak of cerebrospinal fluid World Neurosurg. 2021 Oct 20:S1878-8750(21)01612-0. doi: 10.1016/j.wneu.2021.10.115. Online ahead of print. ABSTRACT OBJECTIVE: We sought to investigate the long-term outcome of pulmonary function for arthrogryposis multiplex congenita (AMC) patients undergoing posterior spinal fusion (PSF) and to further determine influential factors. METHODS: Eighteen AMC patients with a minimum of 3-year follow-up after PSF were prospectively collected. All the patients underwent a pulmonary function test before surgery and at the final follow-up. The percentage predicted values of vital capacity (VC%) and forced vital capacity (FVC%) were recorded. The following radiographic parameters were collected including Cobb angle and thoracic kyphosis. The total lung volumes (TLV) were measured on the image of 3-dimensional computed tomography scan by the reconstruction software. RESULTS: There were 10 males and 8 females with a mean age of 13.8 ± 6.1 years. The mean preoperative VC% and FVC% were 40.5% ± 7.6% and 39.5% ± 4.7%, which were significantly increased to 52.0% ± 7.5% and 51.2% ± 6.8% at the final follow-up (P < 0.001). Besides, there was remarkable improvement in terms of TLV (1.57 ± 0.2 L vs. 2.39 ± 0.6 L, P < 0.001). Remarkable correlations were observed between TLV and pulmonary function tests (r = 0.79, P < 0.001 for VC%; r = 0.78, P < 0.001 for FVC%). Multiple regression analysis showed that 2 variables including Δ thoracic kyphosis and Δ Cobb angle were independently associated with the improvement of pulmonary function. CONCLUSIONS: The pulmonary function of AMC patients can be well improved through PSF surgery. It was remarkably associated with the correction of curve magnitude and restoration of thoracic kyphosis.

Pediatric Intracranial Hypotension and Post-Dural Puncture Headache

xlomafota13 shared this article with you from Inoreader Pediatric Intracranial Hypotension and Post-Dural Puncture Headache Via leak of cerebrospinal fluid Semin Pediatr Neurol. 2021 Dec;40:100927. doi: 10.1016/j.spen.2021.100927. Epub 2021 Sep 3. ABSTRACT Pediatric intracranial hypotension can occur acutely following iatrogenic dural puncture for diagnostic or therapeutic purposes, or chronically from cerebrospinal fluid leak. The incidence of intracranial hypotension in children is not fully known. However, many steps can be taken to reduce the risk of a child developing a post-dural puncture headache. Other causes of intracranial hypotension, such as spontaneous intracranial hypotension or CSF fistulas, are rare and with little pediatric data to guide evaluation and management. This manuscript reviews the risk factors, diagnostic evaluations, and treatments for post-dural puncture headache, as well as a limited discussion of spontaneous intracranial hypotension as it may pertain to children and adolescents.

Epidemiological investigation of tinnitus

xlomafota13 shared this article with you from Inoreader Epidemiological investigation of tinnitus in Sichuan and Chongqing Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Nov 7;56(11):1164-1173. doi: 10.3760/cma.j.cn115330-20201019-00816. ABSTRACT Objectives: To investigate the prevalence and associated risk factors of tinnitus in Sichuan and Chongqing. Methods: We designed a tinnitus epidemiological questionnaire. The multi-stage stratified cluster random sampling methods was applied to obtain study subjects in six areas (Nanchong, Jiangjin, Fengdu, Yunyang, Suining and Ya'an), which were selected for epidemiological investigation. Home visit completion of epidemiological questionnaires was conducted. The trained investigators guided the respondents to fill in the tinnitus epidemiological questionnaires, and the epidemiological status of six areas on prevalence and risk factor was investigated. SPSS 22.0 software was used for statistical analysis. Results: Sampling population were 10 289, in which 9 273 were valid questionnaires. There were 4 281 males and 4 992 females, with an average age of 47.3 years, among which 34.83% (3 230/9 273) had tinnitus. 3.99% (370/9 273) were diagnosed with bothersome tinnitus. In a multivariable logistic regression mod, the following factors were associated with onsetting of tinnitus: sleep disorder [Odds Ratio(OR)=3.74] and noise exposure(OR=1.99). The risk of disease was lowest in the age of 30-40 years old, while the risk of disease was higher for people under 30 and over 40. In another multivariable logistic regression mode, the following factors were associated with having bothersome tinnitus: older people were more likely to suffer from tinnitus, sleep disorders (OR=4.68) and noise exposure (OR=1.56). Conclusions: The prevalence of tinnitus in Sichuan and Chongqing is about 34.83%, but most of the tinnitus is short-lived and has low loudness, which will not affect the patients. Only a small number of patients with tinnitus (3.99%) pers ist and affect their health and need treatment. The occurrence and exacerbation of tinnitus may be related to sleep, age, and noise exposure. PMID:34749455 | DOI:10.3760/cma.j.cn115330-20201019-00816 View on the web Inoreader.

ABSTRACT Objective: To investigate the treatment method and effect of surgical resection and free flap repair of recurrent malignant tumors of maxillofacial paranasal sinus and skull base. Methods: The clinical data of 9 patients with recurrent maxillofacial paranasal sinus and skull base malignant tumors who underwent surgical resection and free flap repair in the Department of Otorhinolaryngology Head and Neck Surgery of Shandong Provincial Hospital from August 2009 to May 2019 were analyzed retrospectively, including 5 males and 4 females, aged 32-69 years. There were 4 cases of squamous cell carcinoma, 3 cases of adenoid cystic carcinoma, 1 case of myoepithelial carcinoma and 1 case of malignant fibrous histiocytoma. All patients were repaired with anterolateral femoral flap. The treatment process an d postoperative effect were analyzed by descriptive statistics. Results: All patients were followed up from 16 months to 6 years. There were 6 cases of recurrence after operation, including 1 case of local recurrence and 5 cases of skull base and craniocerebral recurrence. The median tumor free survival time of recurrent patients was 35 months. Conclusion: Surgical resection and free flap repair can effectively prolong the life of patients with recurrent maxillofacial paranasal sinus and skull base malignant tumors.
