The triangular prism approximation method for volume estimation of deep inferior epigastric artery perforator flap in breast reconstruction.

Background: Many methods to predict the amount of tissue needed for breast reconstruction have been reported, but some require complicated software and special systems. The purpose of this report was to present a simpler method for predicting the volume required for deep inferior epigastric artery perforator (DIEP) flaps. The accuracy of this method was evaluated based on both actual flap design and computed tomography.

Prognosis of Subcutaneous Mastectomy for Special Types of Breast Cancer.

In the treatment of the special type of breast cancer (STBC), the choice of chemotherapeutic agents is often based on the characteristic features of the histological type. On the other hand, the surgical strategy is usually determined by the tumor size and presence of lymph node metastasis, and the indication for immediate reconstruction is rarely discussed based on the histological type. The prognoses of STBC and invasive ductal carcinoma of the breast (IDC) patients who underwent subcutaneous mastectomy (SCM) with immediate reconstruction at our institution were compared.

[A Case of Laparoscopic Total Gastrectomy for Gastric Cancer after Rectus Abdominis Flap Reconstruction for Breast Cancer].

A 60-year-old woman underwent laparoscopic total gastrectomy for gastric cancer with a good postoperative course. At the age of 45, she had underwent skin-sparing total mastectomy, sentinel node biopsy, and right rectus abdominis flap reconstruction for left breast cancer. Since there is a certain risk of abdominal wall hernia after the abdominal flap reconstruction, laparoscopic surgery with less abdominal wall damage might be useful.

Comparative Blink Analysis in Patients With Established Facial Paralysis Using High-Speed Video Analysis.

This study analyzed the blink characteristics of patients with incomplete and complete facial paralysis. The authors measured and compared the palpebral distance, eyelid movement distance, and the eye-closing ratio of blinks in 55 patients with Bell's palsy or Ramsay Hunt syndrome (Bell & Hunt group) and 14 with complete paralysis (Complete Paralysis group). in the Bell & Hunt group, the palpebral distance (7.

Influence of Marker Number and Position on Accuracy of Breast Measurement With Three-Dimensional Camera.

Background: The VECTRA H1 three-dimensional (3D) imaging system (Canfield Scientific, Parsippany, NJ) enables easy 3D image construction and measurement. Although the number and positions of markers on the skin for image synthesis might affect accuracy of measurements, few studies have mentioned the possibility. This study investigated the accuracy and reproducibility of distance measurements using VECTRA H1, focusing on the number and positions of markers.

Immediate breast reconstruction is oncologically safe for node-positive patients: Comparison using propensity score matching.

The oncological safety of immediate breast reconstruction (IBR) in lymph node-positive patients is unclear. In the present study, the impact of IBR on recurrence based on data of patients with axillary lymph node metastases only was examined.The subjects were 232 patients who underwent breast surgery.

Higher body mass index is a more important risk factor than sarcopenia for complications in reconstruction of the deep inferior epigastric perforator.

Background: In recent years, breast reconstruction using autologous tissue after breast cancer surgery has become a common procedure. This study investigated the association between the occurrence of complications in breast reconstruction using deep inferior epigastric perforator (DIEP) flaps and patient risk factors among Asian women.

Methods: This study included cases of breast reconstruction using DIEP flaps performed at our institution.

Study of the protocol used to evaluate skin-flap perfusion in mastectomy based on the characteristics of indocyanine green.

Background: Indocyanine green angiography enables real-time visualization of blood vessels at depths of up to 10 mm beneath the body surface, thereby aiding the evaluation of the viability of skin flaps and predicting necrosis in surgical fields requiring good tissue perfusion. Although skin-flap necrosis also occurs in mastectomy without reconstruction, most studies have focused on reconstructive plastic surgery. Several patients undergoing mastectomy are eligible for postoperative adjuvant therapy, but complications can lead to delays in treatment and thus require prevention.

Chimeric Latissimus Dorsi Flap in One-Stage Reconstruction of Depressor Muscle Dysfunction and Depression Deformity in the Perimandibular Area.

Background: Depression deformity and paralysis of depressor muscles (DMs) may occur following tumor resection in the perimandibular region. Obtaining satisfactory results is challenging. The authors report 3 cases of 1-stage reconstruction by transferring neurovascular chimeric latissimus dorsi (LD) musculo-adipose flaps, with satisfactory results.

One-Stage Simultaneous Augmentation of 2 Regions of 3 Facial Reanimations After Mid Skull Base Surgery by Using a Neurovascular Latissimus Dorsi Chimeric Flap.

We report a patient who underwent secondary reconstruction for facial paralysis involving 2 regions of augmentation and 3 facial reanimations using a neurovascular latissimus dorsi (LD) chimeric flap.A 53-year-old man underwent mid-skull base surgery for a chondrosarcoma at the temporomandibular joint and primary reconstruction using a free anterolateral thigh flap. At 28 months after surgery, he showed temporal and buccal depression and incomplete facial paralysis.

Axillary lymph node recurrence in patients with breast cancer who underwent breast reconstruction using a latissimus dorsi flap after mastectomy.

At our institution (Tokyo Medical and Dental University, Medical Hospital), latissimus dorsi flap (LD flap) reconstruction without a prosthetic implant is a popular surgical strategy following total mastectomy in patients with breast cancer. The LD flap, especially the extended LD flap, is usually rotated anteriorly through the axilla. However, if future additional surgery is required for axillary recurrence after LD flap reconstruction, the flap interferes with the visual field, making the surgical procedure more difficult.

A postzygotic KRAS mutation in a patient with Schimmelpenning syndrome presenting with lipomatosis, renovascular hypertension, and diabetes mellitus.

Schimmelpenning syndrome is a rare neurocutaneous disorder categorized as a mosaic RASopathy due to postzygotic HRAS or KRAS mutations. We report a 6-year-old girl diagnosed with Schimmelpenning syndrome due to a postzygotic KRAS G12D mutation. The patient had three atypical symptoms of Schimmelpenning syndrome: renovascular hypertension, congenital lipomatosis, and diabetes mellitus.

Antiorganic Fouling and Low-Protein Adhesion on Reverse-Osmosis Membranes Made of Carbon Nanotubes and Polyamide Nanocomposite.

We demonstrate efficient antifouling and low protein adhesion of multiwalled carbon nanotubes-polyamide nanocomposite (MWCNT-PA) reverse-osmosis (RO) membranes by combining experimental and theoretical studies using molecular dynamics (MD) simulations. Fluorescein isothiocyanate (FITC)-labeled bovine serum albumin (FITC-BSA) was used for the fouling studies. The fouling was observed in real time by using a crossflow system coupled to a fluorescence microscope.

Simultaneous Surgical Treatment for Smile Dysfunction and Lagophthalmos Involving a Dual Latissimus Dorsi Flap.

Paralytic lagophthalmos and smile dysfunction are serious complications of facial paralysis and various reconstructive procedures have been developed to treat them. Among these procedures, there is no doubt that dynamic procedures are more effective than static ones. The 1-stage simultaneous surgical treatment of these 2 dysfunctions with a dynamic procedure involving a single muscle would be ideal, but no such methods have been reported.
