Dermatosurgical rounds: shark island pedicle flap for skin defect of the alar crease area after basal cell carcinoma removal

A 67-year-old female presented to the Dermatology Department with a tumor formation located on the left lateral side wall of the nose, measuring 1,5/1,2 cm in size, which had been slowly growing over the past few years. The tumor exhibited a shiny, pink-colored surface with a dome-shaped appearance, irregular borders, and superficial telangiectasias, raising clinical suspicion for basal cell carcinoma. Additionally, there was no reported history of skin cancer in any family member or painful sunburns during childhood. The patient was recommended surgical excision under local anesthesia for the suspected lesion.

Optical emission spectroscopy as a method for evaluating the change in Si etching structures profile in ICP SF6/C4F8 plasma: Microstructures

In this work, a method for in situ diagnostics of the etching profile of silicon structures (etching window sizes 15–400 μm) using optical emission spectroscopy was proposed. To determine the relationship between the etching profile and plasma parameters, the influence of technological parameters on the etching characteristics (vertical and lateral etching rate, selectivity in relation to photoresist, and sidewall angle) was studied. As a general parameter, which reflects the changes in plasma characteristics depending on the selected technological parameters, the parameter X (C/F ratio in SF6/C4F8 plasma) was introduced. Based on the results obtained, a general pattern between the lateral etching rate, sidewall angle, and optical emission spectra was identified. Thus, ranges of X values, at which the lateral etching rate does not exceed 5 nm/min for 15–30 μm structures and 15 nm/min for 100 μm structures, were estimated: 0.38 ≤ X ≤ 0.77 and 0.28 ≤ X ≤ 0.46, respectively. For 250–400 μm structures, ranges of X values, at which the sidewall angle is acute, straight, and obtuse, were determined: 0.16 ≤ X < 0.29, 0.29 ≤ X ≤ 0.41, 0.41 < X ≤ 0.75, respectively.

Precision Rhinoplasty Cylindric Burrs-Sidewall Aesthetics.

The development of power instruments has led to great advances in rhinoplasty. It has helped to reduce operating time, minimize damage to the surrounding soft tissues, and allow precision bony modification compared with the use of manual rasps. Burrs help ensure precise results by (i) creating a smooth transition between the lateral nasal sidewall and the face, (ii) treating bony asymmetries, and (iii) producing homogeneous upper and middle thirds that softy translate into the upper lateral cartilages. The aim of this paper is to show applications of cylindrical burrs in rhinoplasty surgery to treat the dorsal upper and middle thirds as well as lateral sidewalls of the nose, regardless of whether the dorsal preservation or structure technique is used. This approach offers a safe, fast, and precise technique that can be used in conjunction with piezo osteotomy to obtain the optimal outcomes.

Nasal Dorsum Rotation-Transposition Flap Associated with Guitar-String Sutures: One-Stage Reconstruction of Large Defects on the Nose.

(1) Background: The preferred reconstructive option for closing small- or medium-sized defects of the distal half of the nose is the use of local flaps. The dorsal nasal (Rieger) flap is suitable for closing medium-sized defects at this location, especially when they are medially located, and are wider rather than tall. We describe a rotation-transposition dorsal nasal flap reconstruction for large nasal defects. The novelty of this design includes the addition of a small transposition lobe to the rotation flap, enabling the acquisition of tissue from either the lateral sidewall or the nasolabial sulcus, facilitating closure with guitar-string sutures. (2) Methods: We conducted a retrospective chart review of all the patients with large defects (>20 mm) of the nose who underwent nasal dorsum rotation-transposition flap repair between January 2019 and November 2022 at a single academic center. (3) Results: Fourteen patients (eight males, six females; ages 47-83, mean age 60 years) with defects (range: 20.00-35.00 mm) on the dorsum and nasal tip were recruited. Follow-up duration ranged from 12 months to 3 years, with all cases showing good or excellent oncologic and cosmetic results. (4) Conclusions: The rotation-transposition dorsal nasal flap was demonstrated to be a reproducible one-stage technique for large defects of the dorsum and nasal tip, with minimal risk of aesthetic or functional complications. Guitar-string sutures allowed the reduction of the defect size, facilitating a smaller flap design.

Over-rotated Rieger flap for a large lateral nasal tip defect reconstruction

A 65-year-old man presented with a Melanoma in situ of the nasal tip. Complete excision was achieved after 2 “Slow Mohs” stages, resulting in a circular 2.7 X 2.4 cm defect involving the right lateral nasal tip, dorsum and sidewall and extending to the perichondrium.

Increased Plasma Ignition Distance Practice may Prevent the Obturator Reflex Occurrences and Compare of its Effectiveness Versus Obturator Block: A Prospective, Randomized, Controlled Study

ObjectiveTo compare the ability of the obturator nerve block (ONB) and increased plasma ignition distance practice (IPDP) techniques to inhibit obturator nerve reflex (ONR) occurring with bipolar transurethral resection of the bladder. MethodsSixty patients who had a tumor placed at the lateral sidewall or had a tumor in another part of the bladder along with the lateral wall were randomly enrolled. Cystoscopic and ultrasonographic examinations and a computerized tomography scanning of the urinary bladder were used to determine the ONB side. Group 1 consisted of patients who had the ONB procedure. Group 2 consisted of patients who had IPIDP. The severity of the ONR was classified as severe, mild, and very mild. The study's primary endpoint was ONR occurrences and successful completion of the surgery. The secondary endpoints were bleeding and bladder perforation. ResultsThere was a significant difference in the occurrence of ONR between the two groups (P = 0.0011). However, there was no significant difference between the two groups in the ability to resect the tumor and complete the surgery (P = .764). There was no correlation between the ONR and the tumor size (P = 0.478). ConclusionOur study concluded that both ONB and IPIDP have comparable results, especially in resecting tumors and completing the operation. IPIDP has some advantages over ONB, such as shorter operative time, lower total costs, and less trained personnel requirements.

Use of Collagen-glycosaminoglycan Silicone Bilayer Matrix for Closure of Post-Mohs Micrographic Surgery Defects on the Nose: A 5-case Series

Introduction. The use of dermal matrices has shown to be reliable and less invasive than skin grafts or skin flaps for wound management. This case series reports the clinical outcomes of 5 patients with defects on the nose post-MMS managed using collagen-glycosaminoglycan silicone bilayer matrix. Materials and Methods. Patient 1 had a BCC of the left nasal lateral sidewall, patient 2 had a BCC of the right nasal ala, patient 3 had a BCC of the nasal dorsum, patient 4 had a BCC of the left medial canthus, and patient 5 had a BCC of the left alar lobule of the nose. Layers of dermal matrix were stacked to augment soft tissue coverage in patient 5. Results. All patients had spontaneous epithelialization of the nose defects following dermal matrix placement. Time to healing ranged from 4 to 11 weeks after dermal matrix placement for defects ranging from 1.44 cm2 to 6.16 cm2. The covering was stable and resulted in satisfactory cosmesis at time of complete epithelialization. Conclusions. Closure of post-MMS nasal defects using bilayer matrix represents a viable option and an advantage over alternative forms of surgical repair when considering cosmesis and patient satisfaction.

Mapping the Mesentery Using ICG.

Indocyanine green (ICG) fluorescent imaging has been used in colorectal surgery to assess intraoperative blood flow to the colon. However, its use has expanded to allow imaging of the lymphatic drainage within the mesentery in cancer resections. This technique can been used for real-time visualization of lymph nodes, and the detection of sentinel lymph nodes, lateral sidewall nodes, metastatic lymph nodes, and peritoneal metastases. Ultimately, this provides a more informative map of the mesentery displaying lymphatics and blood flow. The technique is economical and easy to use by the surgeon intraoperatively. ICG lymphangiography has the potential to aid the surgeon to ensure complete lymphadenectomy is performed in cancer resections.

METHODS: The patient is placed in the 90 degree flank position. A 5 mm laparoscope is placed 4 cm superior to the umbilicus at the midclavicular line, which will aid in visualizing placement of the working robotic ports. The reflection of the peritoneum at the white line of Toldt is identified in order to mark the robotic camera port site 2 fingerbreadths above the iliac crest. Two medial 8-mm robotic ports are placed 2 fingerbreadths above the iliac crest and 8 cm apart using the robotic camera port as reference. Next, with laparoscopic scissors and Kittner Dissector, the lateral side wall attachments to the colon are taken down creating space to safely place the camera port and lateral most trocar. Using a 30 degree upward scope, the peritoneum along white line of Toldt and lateral kidney attachments are incised up to the splenic flexure or hepatic flexure. Complete incision of the peritoneum allows the kidney to naturally flop medially thereby doubling the working space as compared to the traditional approach. Once the white line of Toldt is mobilized, the 4th arm lifts the kidney to place the hilum on traction. After Gerota’s fascia is incised and the hilum identified, standard partial nephrectomy is performed. RESULTS: A total of 15 patients underwent this new technique without any Clavien 1-4 complications. The technique allows for efficient port placement without the need for: blind finger entry, balloon dilation, tedious dissection and sweeping of the peritoneum required for port placement, and extensive defatting of the pararenal fat to create the retroperitoneal space. The port location in this technique is the same as the traditional retroperitoneal approach, thus affording the same view with increased working space and improved visualization of landmarks. Insufflation is also more consistent given less air leaks from inadvertent peritoneal tears and from the balloon dilating port site. CONCLUSIONS: This modified retroperitoneal approach allows for quick, efficient, and safe port placement resulting in larger working space and excellent visualization of anatomical landmarks without the need for complicated retroperitoneal balloon dilation, sweeping of peritoneum for port placement, and defatting of the pararenal fat. Since the development of this technique, we have abandoned the traditional robotic retroperitoneal approach with balloon dilation at our institution.

Electrochemical machining of a rhombus hole with synchronization of pulse current and low-frequency oscillations

Abstract Metal gratings with rhombus holes are widely applied in lightweight aircraft components. Electrochemical machining (ECM) is a nontraditional processing technology with no tool loss and no thermal deformation that has unique advantages for the high-quality processing of rhombus holes. However, the flow paths of the electrolyte in the lateral gap are quite different, and stray corrosion easily occurs on the sidewall due to the different diagonal lengths of a rhombus hole. In this paper, a method was proposed to improve the flow field and processing localization by the synchronization of the pulse power supply and low-frequency oscillations. The on and off positions of the pulse power supply are symmetrical with respect to the wave trough of the oscillation waveform. Based on the coupled simulation of the gas-liquid two-phase flow field and electric field, the effects of assisting oscillations and synchronization of the pulses and oscillations on the void fraction, electrical conductivity, current density, dissolution rate and evolution of the anode profile were investigated. Moreover, the effects of assisting oscillations and synchronization of the pulses and oscillations on the lateral gap, sidewall slope, machining fillet and surface quality were experimentally studied. The experimental results of different ECM methods showed that the coupled simulation was effective and feasible. Moreover, the simulation analysis and experimental results both revealed that the processing accuracy and surface quality of a rhombus hole could be improved by using the synchronized ECM method. The lateral gap at the rhombus hole entrance was only 0.13 mm, the sidewall slope was 0.026 and the surface roughness was Ra0.134 μm under the optimized parameters.

Multi-stages Aesthetic Refinement Following Anterolateral Thigh Free Flap for Head and Neck Reconstruction

Introduction: Multi-stages refinement of a bulky flap after composite defects reconstruction of multiple facial units has been a challenging situation. Goals including restoration of periorbital and malar area and redefining the aesthetic aspects of the units as well as the surrounding nasolabial area with multiple refinements and microfat graft. Methods: A 50-year-old male patient with a history of solitary fibrous tumor underwent wide excision of left periorbital, infraorbital, lateral nasal sidewall, and malar area. The defect is enclosed with Anterolateral Thigh Free Flap (ALT). Bulkiness of the flap, sunken left nasolabial, and asymmetric alar nasal unit were found during outpatient follow-up. These problems lead to the necessity of refinement procedure to reduce the bulkiness to improve the aesthetic outcome of the patient. Microfat graft was the method chosen to volumized the sunken nasolabial and asymmetric alar nasal unit. Results: Patient is satisfied with the result due to improvement of alar nasal units symmetricity and reduced bulkiness of the flap area. No complication was observed. Conclusion: Meticulous planning and staging of the surgical refinement procedures in conjunction with microfat graft results in good aesthetic outcome and satisfies the patient and reduces the possibility of complications.

Total Nasal Tip Defect: Bilateral Lateral Nasal Artery Flaps for Lining Reconstruction

ABSTRACT Background In full-thickness nasal defects, the internal lining is perhaps the most challenging aspect of the three layers to rebuild. Nasal damage is usually more concentrated on the tip, soft triangles, alar wings, and columella, but the lateral nasal arteries are often left intact and the damage to the dorsal sidewalls are normally superficial. Methods Twelve patients who required total nasal reconstruction received a forehead flap placement as external coverage and autologous rib cartilage as structural support. Residual normal/superficial scar tissue flaps on the dorsal sidewalls with lateral nasal artery pedicles were mobilized and designed for internal lining repair without creating secondary donor site damage. The flaps were then turned 180° downward and placed between the alar medial angles and the fornix. Results No total lining flap necrosis occurred in all the patients. Partial necrosis occurred on the distal edge owing to overpressure of the nostril splint to the flaps; however, the wounds eventually healed, and the nasal structural integrity was preserved. The patients were satisfied with the aesthetic results and had no complaints of airway stenosis. Conclusions Lateral nasal artery pedicle dorsal sidewall skin flaps are appropriately thick, providing enough nostril circumferential support to improve airway stenosis. It allows sufficient blood supply and creates no extra donor site damage. Blood vessels and skin flaps are often undamaged, thereby allowing maximum application in total nasal reconstruction.

Small bowel evisceration: a late complication following vaginal hysterectomy

We present a case of small bowel evisceration occurring as a late complication following vaginal hysterectomy and subsequent vault prolapse.Case history: A 92-year-old female presented with sudden onset severe abdominal pain, followed by the sensation of vaginal fullness and the discovery of a large prolapse per vagina, with no history of trauma or sexual intercourse.Past medical history consisted of vaginal hysterectomy 20 years previously with a subsequent sacrospinous vault fixation.On examination, a vaginal vault prolapse was found with 3 feet of oedematous small bowel prolapsed through it. Peristalsis remained visible.An emergency laparotomy was undertaken as a joint procedure between the gynaecology and general surgery teams. The small bowel was gently manipulated back through a 3 cm defect in the vault. Once in the abdomen, it was found to be viable and no resection was required. The vault defect was closed with 1/0 Vicryl and the vault was then fixed to the left lateral side wall of the peritoneum. Routine closure of the abdomen was performed after saline washout.Recovery was complicated by a postoperative ileus requiring nasogastric tube insertion for two days. She recovered well following this and will be followed up in the gynaecology outpatient clinic.Discussion: Small bowel evisceration is a rare complication following hysterectomy. With relatively few cases reported in the literature, incidence is difficult to determine. The most commonly reported risk factors are postmenopausal atrophy, previous vaginal surgery and enterocele. Cases have been reported following both abdominal and vaginal surgical approaches, and are commonly precipitated by sexual intercourse, introduction of a foreign body into the vagina or increased intra-abdominal pressure (Gandhi and Jha 2011).Vaginal evisceration is a gynaecological emergency. Prompt recognition is vital in order to prevent compromise of intra-abdominal contents (Codd et al. 2010). Management requires a multidisciplinary approach and early transfer to theatre for urgent surgical repair; various different approaches have been described, however, if there is any question about organ viability exploration via a midline laparotomy is indicated (Gandhi and Jha 2011).Educational message/learning point: We have presented this case in order to raise awareness of small bowel evisceration as a late complication following hysterectomy. Clinicians in both general surgery and gynaecology should be aware of its potentially non-specific presenting symptoms, as eviscerated organs may not be particularly evident on admission. This is a life threatening condition that requires immediate recognition and management via a multidisciplinary approach.

Reconstruction des pertes de substance superficielles du carrefour des sous-unités de la pointe, de l’aile et de la face latérale du nez : étude sur 36 patients

Conventionally, articles dealing with nasal defects plan reconstructions regarding the aesthetic subunits, imposing their systematic respect. We propose to study the reconstruction of a crossroad region of three subunits, tip, alar lobule and lateral sidewall, where that full compliance is not possible, in our experience of 36patients. Our retrospective study from January2011 to December2012 focused on patients with a defect in this crossroad region that was repaired by skin graft or flap. We described the population of the study, histological type of the lesions, surgical procedures and complications. We evaluated the reconstructions performed with a photographic review 1year post-surgery according to the criteria of symmetry, discoloration, thickness, shrinkage, and rating on the Vancouver Scar Scale, which helped create an overall aesthetic score for the reconstruction. Of 144patients with a nasal defect, 36 of them (25%) were included, presenting a defect in our study area. The reconstruction was made by eight hatchet flaps, eight frontal flaps, seven bilobed flaps, five advanced-rotated lateronasal flaps, four nasolabial flaps, two Rybka flaps and two total skin grafts. The advanced-rotated flap, hatchet flap and bilobed flap had the highest results and scores, according to the criteria assessed. Rybka flap and total skin grafts had the lowest results. The occurrence of a defect in the crossroads seems common. In this indication, specific local flaps had a favourable outcome, including review of the overall esthetic score which was created to standardize the assessment of reconstructions.

Improved room-temperature luminescence of core-shell InGaAs/GaAs nanopillars via lattice-matched passivation

Optical properties of GaAs/InGaAs/GaAs nanopillars (NPs) grown on GaAs(111)B were investigated. Employment of a mask-etching technique allowed for an accurate control over the geometry of NP arrays in terms of both their diameter and separation. This work describes both the steady-state and time-resolved photoluminescence of these structures as a function of the ensemble geometry, composition of the insert, and various shell compounds. The effects of the NP geometry on a parasitic radiative recombination channel, originating from an overgrown lateral sidewall layer, are discussed. Optical characterization reveals a profound influence of the core-shell lattice mismatch on the carrier lifetime and emission quenching at room temperature. When the lattice-matching conditions are satisfied, an efficient emission from the NP arrays at room temperature and below the band-gap of silicon is observed, clearly highlighting their potential application as emitters in optical interconnects integrated with silicon platforms.

Cystic Fibrosis Sinusitis.

Cystic fibrosis (CF) is an autosomal recessive genetic disorder caused by mutations in the CF transmembrane conductance regulator gene(CFTR) resulting in impaired ion transport. Nearly all people with CF will develop chronic rhino-sinusitis (CRS) and present with the characteristic viscous mucus, impaired mucociliary clearance and chronic inflammation/infection of the sinonasal cavity. While some individuals with CF can appear relatively asymptomatic in terms of their sinus disease, commonly reported symptoms include anosmia, headache, facial pain, nasal obstruction, chronic congestion and nasal discharge. Nasal endoscopy typically reveals mucosal edema, purulent discharge and nasal polyposis. Computed tomography (CT) imaging classically demonstrates the distinguishing findings of sinus hypoplasia or aplasia with generalized opacification, medial bulging of the lateral sinonasal sidewall and a demineralized uncinate process. Current treatment for CF sinusitis includes the use of hypertonic saline, topical and systemic steroids, antibiotics and endoscopic surgery. Research investigating novel therapies designed at targeting the primary defect of CF is showing promise for reversal of CF sinus disease, in addition to potential for disease prevention.

Assessment of racking deformation of rectangular underground structures by centrifuge tests

Seismic safety of buried structures has become increasingly important over the past two decades, especially after the destructive earthquakes such as in Kobe, Japan (1995), Kocaeli, Turkey (1999) and Chi-Chi, Taiwan (1999). Some of the embedded structures including pipelines, subways and tunnels collapsed or suffered severe damage in those earthquakes due to inappropriate design. The main difficulty in seismic design is the incorporation of soil–structure interaction effect governed by the relative stiffness (flexibility ratio) between the soil and the embedded structure. This study aims to clarify the effect of flexibility ratio on the dynamic response of rectangular structures buried in dry sand. For that purpose, a series of dynamic centrifuge tests were conducted on two types of box-shaped models with different rigidities under various harmonic motions. The results reveal that the magnitude of dynamic lateral earth pressure and sidewall deformation is highly dependent on the flexibility ratio of the embedded structure. Based on the flexibility ratios, racking deformations observed in centrifuge tests and racking deformations estimated through analytical approaches were evaluated in a comparative manner.

Acute lower gastrointestinal bleeding originating from an arteriovenous fistula of superior rectal artery

Dear Editor: The most common acute causes of lower gastrointestinal (GI) hemorrhage are diverticulosis and angiodysplasia [1]. Arteriovenous fistula (AVF) of the intestine is an uncommon cause of GI hemorrhage [2]. AVF originating from the distal branch of superior rectal artery has never been described before and up to date as a cause of lower GI bleeding. Herein, we report a case of embolization of an AVF originated from the superior rectal artery end branch as a cause of acute lower GI bleeding. An 80-year-old man, with prior history of acute lower GI bleeding episode resolved with supportive treatment 6 months ago, was admitted to our hospital with bright red blood per rectum bleeding. Flexible colonoscopy revealed proximal fresh bleeding without any specific bleeding site. The patient was then referred for a computed tomography (CT) scan. The CT initially suspected an abnormal vessel on the left lateral side wall of the rectum. However, as the patient’s condition remained stable the hemoglobin value decreased despite transfusion, the patient was transferred to the interventional radiology suite for a mesenteric angiography with possible embolization. Angiography showed left superior rectal artery-originated AVF with the suspicion of bleeding. The superior rectal artery branch of AVF was superselectively catheterized with a 2.7 Fr Progreat microcatheter (Terumo, Tokyo, Japan) and embolized with microcoils. Complete hemostasis was achieved after embolization. Very rare cases of inferior mesenteric AVFs have been reported, and a few of them were responsible of acute GI bleeding in the literature [2]. Most of the cases of acute lower GI hemorrhage are controlled with supportive treatment. Persistent bleeding with hemodynamic instability requires further investigation and management [1, 3]. The major risk of embolization is bowel ischemia. As advancements in microcatheter technology have allowed embolization of distal arteries smaller than 1 mm in diameter, thus, the reported rate of colonic ischemia has reduced to approximately 3–4 % in recent studies [1]. Here, we have presented a very rare case of embolization of an intestinal AVF originated from the end branch of superior rectal artery. We suggest that superselective embolization may be a more safe treatment option in some types of acute lower GI bleeding.
