ABSTRACT

PURPOSE: Partial nephrectomy is gaining, nowadays, more interest in oncologic kidney surgery. This type of surgery requires the good knowledge of vascular renal anatomy to make it safe and to guarantee good functional and oncological outcomes. This paper exposes the clinical implication of the arterial renal anatomy in nephron-sparing surgery.

METHODS: This is a cadaveric st udy of 71 human kidneys performed at Charles Nicolle mortuary. The right and left kidneys with surrounding tissues were removed en bloc with the adjacent part of the aorta and inferior vena cava, cleared and studied. Colored resin was injected in each artery, vein, and urinary ducts, with a specific color code for each structure. Corrosion technique was used to eliminate the surrounding tissue, leaving only the colored resin matrix. The Ternon anatomic classification of the inferior polar artery, based on its emergence point was used.

RESULTS: Multiple renal arteries were noted in 9.85% of casts. Anterior and posterior division of main renal artery was found in 95.7% of cases. Posterior segmental artery crossed posteriorly the upper caliceal infundibulum and the renal pelvis in 93% of cases. The upper renal pole was vascularized by an apical segmental artery in 16.9% of cases and a superior polar artery in one case (1.4%). The mid pole of the kidney was supplied by a unique an terior branch and a single posterior branch in 40% of cases. Inferior polar artery was found in 52 casts (73.23%). Type I of Ternon was found in 6 casts (11.53%), Type II in 25 cases (48.07%), Type III in 19 cases (36.53%), Type IV in 2 cases (3.84%), and type V in 13 casts (25%).

CONCLUSION: Renal vascular anatomy presents large variations. Good knowledge of the segmental arterial anatomy of the kidney is a primordial to a safe partial nephrectomy. Good preoperative vascular mapping can be of great help for the surgeon.

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2021 Apr 18:S1748-6815(21)00196-0. doi: 10.1016/j.bjps.2021.03.092. Online ahead of print.

ABSTRACT

BACKGROUND: Peripheral facial palsy (PFP) (paralysis) can be a devastating condition that has been shown to have associations with increased depression and worse quality of life. The aim of the present study is to better understand the complex association of psychological distress with the duration, severity, and age of patients with PFP. We hypothesize that a shorter duration of PFP is associated with higher levels of psychological distress.

METHODS: Fifty-nine patients with PFP that existed longer than 3 months were included in this study. The Hospital Anxiety and Depression Scale (HADS) was used to assess the presence and severity of anxiety and depressions. Spearman's correlation analysis was used to determine correlation between psychological distress, duration, severity of the PFP, and age.

< p>RESULTS: Fifty-nine patients were included in this study, of whom 22 were male and 37 were female. The mean age was 55.6 ± 14.6 years and mean duration of PFP from onset ranged from 3 months to 35 years (with a mean duration of 5.39 ± 6.06 years). Twenty-eight patients had left-sided PFP, 30 patients had right-sided PFP, and one patient had bilateral PFP. The majority were caused by Bell's palsy (50.8%). In the group with a duration less than 5 years, there were five (12.8%) patients having a score between 11 and 15 (on HADS) compared to two (10%) patients in the group with a duration of 5 years or more(p = 0.04).

CONCLUSION: There seems to be an association between moderate depression and duration of the PFP. Further studies need to substantiate our findings.

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2021 Apr 20:S1748-6815(21)00188-1. doi: 10.1016/j.bjps.2021.03.085. Online ahead of print.

ABSTRACT

BACKGROUND: Long-term facial nerve palsy has a highly negative impact on patients' quality of life. In 2016, Alam reported one case of facial reanimation with the sternohyoid muscle after publishing a preclinical study in 2013. Despite the potentially ideal characteristics of this muscle for reanimation of facial palsy, this technique is still not widely used. The objective of our description of cases was to present the clinical results obtained with the surgical procedure and the study on cadavers to confirm the anatomical findings.

METHODS: This work describes the anatomical study of the vascular and nervous pedicle of the sternohyoid muscle compared with clinical results from a series of patients with long-term facial paralysis who underwent facial reanimation between June 2016 and September 2019, through the insertion of the sternohyoid muscle into the masseteric nerve.

RESULTS: The anatomical study was conducted in eight human hemi-necks. In five cases (62%), the vascular pedicle was provided by the superior thyroid artery, and the entrance of the ansa cervicalis to the muscle was constant 1.8 cm from the distal insertion. This series included ten patients who underwent the surgery technique of facial reanimation using the sternohyoid muscle, with a 90% (n = 9) of reinnervation; 100% (n = 10) of flaps were viable, and none of the patients showed complications in the donor area.

CONCLUSIONS: The sternohyoid muscle showed itself as a reliable muscle as a free flap in facial reanimation, and alternative to the gracilis flap. The surgical technique was safe, without any complications, with excellent excursion, recovery, and aesthetic results.

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2021 Apr 23:S1748-6815(21)00227-8. doi: 10.1016/j.bjps.2021.03.123. Online ahead of print.

ABSTRACT

Explantation of breast implants has become increasingly common. This study aimed to analyze breast auto-augmentation following implant explantation (using a laterally designed anterior intercostal artery perforator [AICAP] flap) in patients who did not need new implants and required volume preservation. Twenty-four patients (48 breasts) aged 31-67 years (mean, 52.4 years) with body mass index (BMI) between 24.43 and 29.34 (mean, 27.32) kg/m2 underwent this procedure. All patients had implant-related problems, such as recurrent capsular contracture (n=11), seroma (n=2), animation deformity (n=3), rupture-induced bleeding (n=5), and breast implant disease (n=3). Sizes of implants removed ranged from 215 to 355 ml. The mean flap size was 23.9 cm × 7.5 cm, and the average flap thickness was 2.3 cm (range, 2.0- 3.2 cm). Flap survival was clinically examined postoperatively by ultrasonography. Pre- and postoperative final breast volumes were compared by direct patient observation and independent photograph observation by three plastic surgeons according to a 4-point scale (bad=1, regular=2, good=3, and excellent=4) and the brassiere size. All flaps were completely viable after harvesting. No postoperative signs of fat necrosis were observed, and independent plastic surgeon evaluation revealed good and excellent results in all cases. Patient satisfaction evaluated by BREAST-Q data was >90%. This new design, AICAP flap (with a lateral thoracic extension), can be safely used for breast volume restitution after breast implant explantation with high patient satisfaction. This flap exhibited reasonable potential of providing additional volume in patients who undergo implant explantation and require the preservation of similar volume.

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2021 Apr 18:S1748-6815(21)00216-3. doi: 10.1016/j.bjps.2021.03.112. Online ahead of print.

ABSTRACT

BACKGROUND: Changes of the lymph flow from the chest wall after mastectomy and sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (Ax) has yet to be understood. This study aimed to investigate the effect of axillary surgery on lymphatic flow from the chest wall in patients who have undergone mastectomy, including those have undergone breast reconstruction and vascularized lymph node transfer (VLNT).

METHODS: Following mastectomy in 100 breasts, the directions of lymph flow from the chest wall was compared between the SLNB omission, SLNB, Ax, and Ax followed by VLNT groups using indocyanine green (ICG) lymphography in cross-sectional study. Lymph flow on the deep epigastric artery perforator (DIEP) flap was also investigated.

RESULTS: Lymph flow directing to the ipsilateral axill a was observed more frequently after SLNB than Ax (48% vs. 12.5%; p = 0.005); however, no significant difference was observed in the frequency of contralateral axillary route adoption between them (8% vs. 15%; p = 0.65). In the VLNT group, lymph flow to the ipsilateral axilla was not observed at a significantly higher frequency than in the Ax group (12.5% vs. 12.5%, p = 1.00). On the transferred DIEP flap, the lymph flowed anterograde or retrograde parallel to the anatomic course of the lymphatic vessels.

CONCLUSION: To visualize the direction of lymph flow of the chest following mastectomy, ICG lymphography may be useful to discern the direction in which malignant neoplasms, including lymphoma, are transported and to plan for lymph flow restoration.

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2021 Apr 20:S1748-6815(21)00212-6. doi: 10.1016/j.bjps.2021.03.107. Online ahead of print.

ABSTRACT

BACKGROUND: Transgender women and transfeminine spectrum nonbinary individuals may opt for breast augmentation. The aim of the study is to analyze the complications, surgical trends, and long-term follow-up of breast augmentations in this population over the past 30 years.

METHODS: All transgender women and nonbinary individuals who underwent breast augmentation at our center between 01-1990 and 01-2020 were retrospectively identified. A retrospective chart study was conducted, recording individual demographics, implant characteristics, surgical timing, postoperative complications or other reasons requiring reoperation, and implant survival. A literature search was performed in MEDLINE on clinical outcomes and revision surgery of this procedure.

RESULTS: A total of 527 individuals were identifie d. Median clinical follow-up time was 11.2 years (interquartile range 3.3-17.5). Median implant size increased significantly over the last years (1990-1990 median 275cc, 2000-2009 252cc, 2010-2019 375cc, p<0.01). Most individuals underwent breast augmentation and genital gender-affirming surgery in one-stage. Reoperations due to short-term complications were infrequent (hematoma (0.4%) or infection (0.4%)). Reoperations due to long-term complications comprised: implant rupture (5.7%), capsular contracture (4.9%), aesthetic problems (3.8%), low-grade infection (0.4%), or seroma (0.6%). In total, 2.5% of individuals requested larger implants. After performing the literature search and manuscript screening, 9 out of 115 identified studies were included for review. Follow-up time ranged from 30 days to 5.5 years. Reported complications requiring reoperation were capsular contraction (range 0.0-5.6%), asymmetry (3.6%), hematoma (range 0.0-2.9%), infection (range 0.0-0.9%) and implant rupture (0.7%), CONCLUSION: Implant-based breast augmentation is a safe procedure in transgender individuals.

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2021 Apr 22:S1748-6815(21)00226-6. doi: 10.1016/j.bjps.2021.03.121. Online ahead of print.

ABSTRACT

OBJECTIVES: This study aimed to perform a surgery-related and patient-related outcome analysis of a case-matched series of patients treated with computer-assisted surgery (CAS) and traditional freehand surgery.

METHODS: A total of 153 patients who underwent mandibular reconstruction by VFF were included from Jan 1999 to Dec 2019. The mandibular resection and reconstruction were performed by four experienced oral and maxillofacial surgeons. Reasons for reconstruction were oncologic, osteoradionecrosis, trauma, and osteoporosis. All the patients were followed up postoperatively for at least 1 year. Eighteen pairs were formed with the matched cohort consisting of a total of 36 patients who underwent primary mandibular reconstruction without additional combined flaps. The surgery-related and patient-relat ed continuous and categorical parameters were assessed in both groups.

RESULTS: The average operation time and bleeding volume in the CAS group were less than those in the non-CAS group. Additionally, both hospitalization and ICU days were lower in the CAS group without any significant difference. The only significant finding related to surgical parameters was observed for the ischemia time, which was lower in the CAS group.

CONCLUSIONS: Computer-assisted surgery indicated improved efficiency considering reduced ischemia time, operation time, and length of hospital stay with lower early complications than that of conventional surgical procedures. It can thus be considered as an optimized alternative to the freehand approach.

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2021 May 22. doi: 10.1007/s00405-021-06873-8. Online ahead of print.

ABSTRACT

PURPOSE: The scope of this research endeavor was the determination of the applicability of over the counter mouthwash solutions in reducing the viral load in the saliva of COVID-19 patients and hence decreasing their infectivity. Beyond that, new experimental mouthwashes were investigated in terms of a possible positive immune modulation, which might offer an additional opportunity for a positive pharmaceutical effect.

METHODS: The effectivity of the mouth washing solution was determined on 34 hospitalized COVID-19 patients by measuring the viral load by RT-qPCR in pharyngeal swabs, which were taken before and after rinsing. The inflammatory modulation thru the experimental solutions was assayed in an in vitro model of virus infected nasopharyngeal epithelium cells.

RESULTS: The clinical pilot study demonstrated that the mouth rinsing solution was able to reduce the viral load by about 90% in the saliva of most patients. This reduction was determined to persist for about 6 h. In the experimental solutions, the ingredients dexpanthenol and zinc were able to reduce the expression of proinflammatory cytokines in the cell culture model, while the antiviral response was not altered significantly.

CONCLUSION: We recommend the application of mouth wash solutions to COVID-19 patients, since our results indicate a reduction in infectivity and might govern the protection of health care professionals. Further improvement to the over the counter formulation can be made by utilizing zinc and dexpanthenol, as they which might be beneficial for the patients' health.

Abstract

After removal of an infiltrative BCC of the auditory meatus, a soft tissue defect of the temporal-mastoid area with bone exposure, needed reconstruction. Several options have been taken into account and a simple yet effective solution has been found following the spare-parts principle. The ear lobe, preserved during cancer removal, was split and used as a thin skin flap. Adequate coverage of the bone exposure and resurfacing of the external auditory canal was obtained with minimal donor site morbidity and a short surgery in a fragile patient with several comorbidities. The spare-parts strategy can provide successful solution to difficult reconstructive cases regardless of the anatomical area.

Abstract

The current study aimed to adapt and validate the speech handicap index into the Kannada language, and also to investigate its psychometric properties in Kannada speaking individuals with oral and oropharyngeal cancers. This is a cross-sectional study and it was carried out in two phases. The first phase dealt with the translation of the English version of SHI into the Kannada language, and its validation on 95 healthy individuals and 25 individuals with oral or oropharyngeal cancer. The second phase dealt with the investigation of speech-related quality of life among 50 Kannada speaking individuals with oral and oropharyngeal cancers. The SHI-K has very good internal consistency (Cronbach's Alpha is 0.98) and exhibited good test–retest reliability (ICC = 0.94). The mean scores of the disordered group, for the psychosocial scores (t (118) = 25.87, p < 0.01), for speech scores (t (118) = 19.74, p <� ��0.01), for total SHI scores (t (188) = 26.45, p < 0.01), for overall rating (t (118) = 16.81, p < 0.01) were statistically significant and greater than the healthy group (p < 0.01). A statistically significant association was found between clinical-stage, total SHI scores, and rating [χ2 (4, N = 50) = 3.82, p = 0.02], but not for sex, tumor site, and type of treatment received. SHI-K is a valid and reliable tool to assess the speech-related quality of life of individuals with speech disorders. This tool can allow clinicians to plan better rehabilitation, and it can be used as an outcome tool for any treatment studies. The findings of the study emphasize the importance of considering patient priorities before commencing surgical or therapeutic interventions.

“An Observational Study on Association of Clinical Diagnosis of Diphtheria with Smear and Culture Test: A Tertiary Care Hospital, Jaipur“

xlomafota13 shared this article with you from Inoreader

12070.jpg

Abstract

Diphtheria is an acute infectious upper respiratory tract disease caused by toxigenic strains of Corynebacterium diphtheria and can lead to significant morbidity and mortality in all the age groups. Most of the time diagnosis of diphtheria is clinical. There may be a dirty white patch covering one or both tonsils on examination for which throat swabs are collected for Kleb's-Loeffler's Bacillus (KLB) by direct microscopy and for culture and sensitivity of the organism. To find out the association between clinical diagnosis of diphtheria with smear and culture positivity. 674 cases of Clinical diphtheria were admitted from June 2017 to September 2020 at a tertiary care hospital, Sawai Mansingh Hospital, Jaipur. throat, difficulty in swallowing and swelling in the neck. Out of 674 patients of clinical diphtheria, majority 610 cases (90.5%) were found to have both KLB smear and culture negative. 13 cases (1.9%) were found to have both KLB smear and culture posit ive. 19 cases (2.8%) were found to have KLB smear positive and culture negative and remaining 32 cases (4.8%) were found to have KLB smear negative and culture positive. Out of 19 patients of KLB smear positive,11 cases (3.5%) were found to have complications. Out of 32 culture positive patients,24 cases (7.7%) were found to have complications. Out of 13 patients of both KLB smear and culture positive,11 cases (3.5%) were found to have complications. Our study concluded that the negative report of KLB smear and culture does not rule out diphtheria and it is evident that percentage of complication is high in patients with either KLB smear or culture or both positive with respect to both being negative. The correlation is found to be significant (p < 0.001).
