Background: The variable relationship between the orbicularis supercilii and frontalis muscles may cause side effects with botulin toxin; steadily frowning is the usual recommendation. Eliminating the need to frown until all injections are over might enhance efficacy and lessen the neurotoxicity risks related to muscle exhaustion., Objectives: The goal of this study was to investigate whether the digital caliper-assessed distances between the medial and lateral corrugator injection sites and the midline differed significantly in patients persistently frowning from patients resting., Methods: Seventy-six individuals with glabellar wrinkles treated with botulinum toxin in the authors' private practices for glabellar lines voluntarily contributed their retrospective data about the positions of injection sites. The investigators had freely chosen to inject the medial and lateral sections of the corrugator supercilii during persistent maximum frown or at rest., Results: The mean differences in distances between the medial and lateral injection points and the estimated midline were clinically trivial (1.0 ± 1.28 and 1.5 ± 2.53 mm, respectively), although the distances between the relaxed and contracted medial and lateral injection sites exceeded 1.8 and 2.5 mm in 33.9% and 46.4% of patients, respectively. Distance differences, not significant before 40 years old, were statistically significant only for the lateral injections in older patients (on average, 1.9 ± 3.01 mm)., Conclusions: The average distances from the medial and lateral injection points and the midline appear minimally different in patients who frown until all injections are over and, conversely, patients who rest. Persistently frowning might be advisable only in patients older than 40. Facial asymmetries may be a confounding factor., (© The Author(s) 2023.

Upper blepharoplasty is a common aesthetic surgery procedure which is frequently performed wide awake, under local anesthesia. However, advancements concerning the patients' perception during and after the procedure are still needed. This study aimed to evaluate the efficacy of a new method for local anesthetic infiltration in the upper eyelid comparing it to the traditional needle injections.A prospective, randomized, and clinical trial was conducted on 20 patients who underwent upper eyelid blepharoplasty in local anesthesia. After randomization, one eyelid was infiltrated using a Nanosoft technology needle, while on the contralateral side traditional needle injections were performed. Preoperative demographics, Fitzpatrick, and SNAP test were recorded. Postoperative patients visual analog scale (VAS) scores for both infiltration methods and ecchymosis and edema were recorded.Our results showed that the mean VAS scores for perceived pain were significantly lower on the eye infiltrated with Nanosoft technology ( p  < 0.05). Furthermore, the rate of postoperative ecchymosis and edema were also significantly lower with Nanosoft technology ( p  = 0.0012 and 0 = 0.0197, respectively). All 20 patients were satisfied with outcomes, and there were no major complications or need for a revision.Our case series study suggests that Nanosoft technology may be a more effective and efficient method for the local anesthetic infiltration in upper eyelid blepharoplasty in reducing discomfort and downtime for the patient., Competing Interests: None declared., (Thieme.

Objectives and background: Tissue stabilized-guided subcision (TS-GS) treatment has emerged as a single session treatment for cellulite dimples. To date, studies on a few patients were reported. We present data concerning efficacy and safety of TS-GS for cellulite in a cohort of Italian patients. Patients and Methods: This is a retrospective study involving 122 patients requiring cellulite treatment, classified according to validate cellulite dimples scale at rest, at T0. TS-GS technique is assessed in terms of efficacy (masked evaluations of pre- and post-treatment pictures, satisfaction of patients and variations in cellulite dimples scale at rest), safety of results at 12 months follow-up (T1). U nivariate and multivariate analyses were carried out to evaluate variables associated with the size effect. Results: Masked evaluations of 112 patients completing the study resulted in the correct selection of pre- and post-treatment images in all cases and all patients were satisfied. The mean cellulite dimples scale at rest score improved ≥1 point at T1. We found a significant association between size effect, higher satisfaction ( p < .01), cellulite grading at T0 ( p < .01), higher BMI ( p = .037); a higher BMI was correlated to an increased cellulite grading at T0 ( p = .02). Only minor and temporary adverse events were reported. Conclusions: We confirm herein the clinical efficacy and safety of TS-GS for cellulite dimples treatment in a cohort of Italian patients assessed with the validated cellulite dimples scale at rest.

Adrenal myelolipoma is an uncommon tumour of the adrenal gland, usually unilateral, frequently associated with hypertension and obesity, with a benign biological behaviour and without hormonal activity, first described in 1905. The neoplasm consists of adipose tissue and myelopoietic cells of the bone marrow. These tumours have a very slow but continued growth and their volume and weight vary significantly from small lesions of a few grams to huge masses weighing up to several kilograms. If symptoms occur, surgery should be performed without delay, especially for large myelolipomas that are at high risk of spontaneous rupture with haemorrhage and life-threatening shock. In this report a case of a 43-year-old male with a 22 x 18 x 9 cm giant myelolipoma, weighing 3500 g and originating from the right adrenal gland is described. The large mass dislocating and compressing the inferior vena cava, was removed surgically. The early postoperative course and the late outcome were favourable without recurrence after 30 months. The different aetiological hypotheses of this rare neoplasm and its clinical features, diagnosis and treatment are discussed.

Multicentricity of gastrointestinal stromal tumors (GISTs) has been described only in patients with neurofibromatosis type 1 (NF1) or within the small intestine, and different pathogenetic mechanisms are involved. We report a case of synchronous sporadic gastric and jejunal GISTs, which were resected laparoscopically in a 67-year-old man. Immunohistochemical analysis revealed that both lesions were KIT (CD117)-positive, but that the gastric lesion was CD34-positive, whereas the jejunal one was Vimentin-, S-100-, and SMA-positive. Molecular analysis of mutations in KIT exons 9, 11, 13, and 17, and in PDGFRA exons 12 and 18 revealed the presence of a gastric sporadic GIST with a KIT mutation of the exon 11 and a jejunal sporadic GIST without KIT or PDGFRA mutations. To our knowledge, this is the first report of laparoscopically resected synchronous sporadic gastric and jejunal GISTs.

We describe a case of female patient presenting with acute biliary symptoms and severe haemobilia due to the presence of a large metastasis in the gallbladder wall from renal cell carcinoma treated by radical nephrectomy 16 years before. CT examination also showed the presence of multiple small round metastases from renal carcinoma in the pancreas, subsequently confirmed surgically and pathologically.

Zenker's diverticula commonly occur in the elderly, and quality of life is often impaired by typical symptoms such as dysphagia, regurgitation, halitosis, cough and aspiration pneumonia, malnutrition and weight loss. The "gold standard" treatment for pharyngo-oesophageal diverticula is the resection of the sac via left lateral cervicotomy and cricopharingeal myotomy. In the last decade, with the fast development of minimally invasive techniques, an endoscopic stapled approach has been proposed. This procedure rapidly encountered the favour of gastroenterologists because patients with Zenker's diverticulum often present serious co-morbidities and seem to benefit from the minimally invasive technique; but the crucial point in the treatment of Zenker's diverticula, in addition to the sac resection, is the myotomy of the cricopharyngeal muscle fibres and this could not be safely and completely achieved in endoscopic stapling owing to the risk of vascular lesions and incomplete sectioning of the sac. Moreover, many studies have reported similar results between open and endoscopic procedures in terms of postoperative morbidity and mortality, showing better functional outcomes in surgical patients even if elderly and presenting co-morbidities. In this report, the case of a 95 year-old patient, one of the oldest operated on for this disease and reported in the literature, is described. He was affected by a massive 8 cm Zenker's diverticulum and an oesophageal motility disorder (dyskinesia), with significant co-morbidity. Surgical diverticulectomy combined with cricopharyngeal myotomy was performed with excellent early and late results.

Small bowel metastases from primary lung cancer have rarely been reported and a single symptomatic metastasis to the small bowel is a rare occurrence. In the case reported here there was no evident additional site of metastatic disease and the diagnosis was made on the basis of morphology and immunohistochemistry analysis using CK 07, CK 20 and TTF-1 monoclonal antibodies. However, even in patients in whom the intestine is the sole metastatic site, the prognosis is dismal and most of patients die within 2 months.

We describe the case of a young woman with a recurrent right Bernard-Horner's syndrome associated with the onset of intermittent supraclavicular mass. Surgical excision of the mass revealed the endometrial pattern of the tumor and the close relationship between Bernard-Horner's syndrome and thoracic endometriosis. No other case of this syndrome has been reported in the literature.

Over the past few years, incidental thyroid microcarcinoma has become a frequent disease and its incidence in some reports is considerable. Discovering new cases depends on the extended indications for total thyroidectomy for benign disease, on progress in the field of diagnostic instruments (ultrasound, scintigram, fine needle biopsy for cytology, CT scan, MRI), and on the pathology examination of very thin slices of specimens. In spite of the high incidence reported in some autopsy series, suggesting that this tumour may have a good prognosis, some Authors report an overall incidence of up to 11% of local recurrence, metastasis or mortality. For all these reasons the surgical treatment of incidental thyroid microcarcinoma is still controversial. The aim of this study was to estimate the incidence and examine the clinical-pathological findings of incidental thyroid microcarcinoma in a series of 100 consecutive thyroidectomies and to evaluate whether complete removal of the gland should be adopted in all cases. In the present series the incidence of incidental thyroid microcarcinoma was 21.6% (19/88). Total thyroidectomy was considered the treatment of choice for diffuse benign disease and appeared to be necessary for both the diagnosis and treatment of incidental thyroid microcarcinoma.

We hereby present the case of a 55-year-old woman with an iatrogenic tracheal laceration that occurred during double lumen intubation for left pneumonectomy. Conservative treatment was performed and the patient was discharged 12 days after surgery. No major sequelae after 3 months of follow-up were observed.

Over the last few years, incidental thyroid microcarcinoma (TMC) has become a frequent disease and its incidence in some reports is considerable. The discovery of new cases depends on the progress of the diagnostics (US scan, fine needle biopsy and cytology, CT, MRI), on the extended indications to thyroidectomy for benign disease and on the attention in pathologic examination of the specimen. The clinical evolution of this disease is not well known: in spite of a high incidence reported in some autoptic series, suggesting that this tumour could have a good prognosis, some authors report an overall incidence of up to 11% of local recurrence, metastasis and mortality. For these reasons the treatment of TMC is still controversial today. Aim of this study was to estimate the incidence and the clinico-pathological findings of TMC over a one year period of total thyroidectomies for diffuse benign thyroid diseases, and to evaluate, on the basis of the frequency of incidental microcarcinoma, if the surgical procedure of complete removal of the gland should be adopted in any case. In this series no patient had pre-operative diagnosis or tentative diagnosis of carcinoma and the incidence of TMC at the final histologic examination was 27.4%. Total thyroidectomy confirmed to be the treatment of choice for diffuse benign diseases and appeared necessary to obtain both, diagnosis and treatment of incidental TMC.
