Psychometric Properties of Assessment Tools for Depression, Anxiety, Distress, and Psychological Problems in Breast Cancer Patients: A Systematic Review

Objective@#Various and accurate psychiatric assessments in patients with breast cancer who frequently suffer from psychological problems due to long-term survivors are warranted. This systematic review aimed to investigate the current evidence on psychometric properties of psychiatric assessment for evaluating psychological problems in breast cancer patients. @*Methods@#This systematic review progressed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Four electronic databases such as Web of Science, PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature were searched. This study protocol was registered on Open Science Framework. @*Results@#Of the 2,040 articles, 21 papers were finally included. Among them, only five studies showed the performance of psychiatric assessment tools. Among 13 assessment tools used in the selected articles, the Hospital Anxiety and Depression Scale (HADS), Distress Thermometer (DT), or Mini-Mental Adjustment to Cancer Scale was frequently used for the evaluation of psychological problems. The DT and Psychosocial Distress Questionnaire-Breast Cancer showed acceptable performances for the prediction of depression and anxiety assessed by the HADS. @*Conclusion@#This systematic review found psychiatric assessment tools with acceptable reliability and validity for breast cancer patients. However, comparative studies on reliability and validity of various scales are required to provide useful information for the selection of appropriate assessment tools based on the clinical settings and treatment stages of breast cancer. Joint research among the fields of psychiatry and breast surgery is needed for research to establish the convergent, concurrent, and predictive validity of psychiatric assessment tools in breast cancer patients.

The analgesic efficacy of a single injection of ultrasound-guided retrolaminar paravertebral block for breast surgery: a prospective, randomized, double-blinded study

Background@#The thoracic paravertebral block is an effective analgesic technique for postoperative pain management after breast surgery. The ultrasound-guided retrolaminar block (RLB) is a safer alternative to conventional paravertebral block.Thus, we assessed the analgesic efficacy of ultrasound-guided RLB for postoperative pain management after breast surgery. @*Methods@#Patients requiring breast surgery were randomly allocated to group C (retrolaminar injection with saline) and group R (RLB with local anesthetic mixture).The RLB was performed at the level of T3 with local anesthetic mixture (0.75% ropivacaine 20 mL + 2% lidocaine 10 mL) under general anesthesia before the skin incision. The primary outcome was cumulative morphine consumption using intravenous patient-controlled analgesia (IV-PCA) at 24 hour postoperatively. The secondary outcomes were the visual analogue scale (VAS) scores at 1, 6, 24, and 48 hour postoperatively and the occurrence of adverse events and patient satisfaction after the surgery. @*Results@#Forty-six patients were included, 24 in group C and 22 in group R. The cumulative morphine consumption using IV-PCA did not differ between the two groups (P = 0.631). The intraoperative use of remifentanil was higher in group C than in group R (P = 0.025). The resting and coughing VAS scores at 1 hour postoperatively were higher in group R than in group C (P = 0.011, P= 0.004). The incidence of adverse events and patient satisfaction was not significantly different between the two groups. @*Conclusions@#A single injection of ultrasound-guided RLB did not reduce postoperative analgesic requirements following breast surgery.

Recurrent late seroma after immediate breast reconstruction with latissimus dorsi musculocutaneous flap

The latissimus dorsi musculocutaneous flap (LDMCF) is widely used for breast reconstruction. However, it has the disadvantage of frequent seroma formation at the donor site, and late seroma has also been reported. The authors report histological findings after the surgical treatment of a late, repeatedly recurrent seroma at 10 years after breast reconstruction with LDMCF. In 2008, a 66-year-old female patient underwent immediate breast reconstruction with LDMCF. In 2015, a late seroma was found at the donor site. After aspiration and drainage, the seroma recurred again in 2018. Total surgical excision of the seroma was performed and bloody-appearing fluid was identified in the capsule. The excised tissue was biopsied. Histological examination revealed no evidence of blood in the fluid, and multinucleated giant cells with amorphous eosinophilic proteinaceous material were identified. The cyst was suggestive of chronic granulomatous inflammation. There was no recurrence at 8 months postoperatively. The patient described herein underwent surgical treatment of late seroma that recurred after immediate breast reconstruction with LDMCF, and histological findings were identified. These results may be helpful for other future studies regarding late seroma after breast reconstruction with LDMCF.

Application of Deep Learning System into the Development of Communication Device for Quadriplegic Patient / 대한신경손상학회지

OBJECTIVE: In general, quadriplegic patients use their voices to call the caregiver. However, severe quadriplegic patients are in a state of tracheostomy, and cannot generate a voice. These patients require other communication tools to call caregivers. Recently, monitoring of eye status using artificial intelligence (AI) has been widely used in various fields. We made eye status monitoring system using deep learning, and developed a communication system for quadriplegic patients can call the caregiver. METHODS: The communication system consists of 3 programs. The first program was developed for automatic capturing of eye images from the face using a webcam. It continuously captured and stored 15 eye images per second. Secondly, the captured eye images were evaluated for open or closed status by deep learning, which is a type of AI. Google TensorFlow was used as a machine learning tool or library for convolutional neural network. A total of 18,000 images were used to train deep learning system. Finally, the program was developed to utter a sound when the left eye was closed for 3 seconds. RESULTS: The test accuracy of eye status was 98.7%. In practice, when the quadriplegic patient looked at the webcam and closed his left eye for 3 seconds, the sound for calling a caregiver was generated. CONCLUSION: Our eye status detection software using AI is very accurate, and the calling system for the quadriplegic patient was satisfactory.

Early Stage Lymphedema in Breast Cancer Patient Detected by Indocyanine Green Lymphography but not by Lymphoscintigraphy: A Case Report

Secondary upper extremity lymphedema after lymph node dissection in breast cancer patients is a major complication affecting their quality of life. As lymphatic function is compromised before symptoms develop in most cases, early diagnosis and intervention before symptomatic manifestation is known to prevent severe progression of lymphedema. In this case report, we present a patient with secondary lymphedema, whose disease could be diagnosed at an early stage using indocyanine green (ICG) lymphography. The patient had mild edema of the left upper extremity that regressed with elevation, had normal lymph vessel distribution without dermal backflow pattern in lymphoscintigraphy. Her symptom improved after early prescription of complex decongestive physiotherapy. We conclude that ICG lymphography could be an effective diagnostic tool in addition to other imaging methods, for early diagnosis and intervention of lymphedema.

A novel technique for placing titanium mesh with porous polyethylene via the endoscopic transnasal approach into the orbit for medial orbital wall fractures

BACKGROUND: The endoscopic transnasal approach is widely used for reconstructing the medial orbital wall by filling it with a silicone sheet or Merocel, but this technique has the disadvantage of retaining the packing for a long time. To overcome this drawback, a method of positioning an absorbable plate in the orbit has been introduced, but there is a risk of defect recurrence after the plate is absorbed. Here, the authors report the results of a novel surgical technique of placing a nonabsorbable titanium mesh with porous polyethylene into the orbit through the endoscopic transnasal approach. METHODS: Fourteen patients underwent surgery using the endoscopic transnasal approach. Preoperative computed tomography (CT) was used to calculate the size of the bone defect due to the fracture, and the titanium mesh was designed to be shorter than the anteroposterior length of the defect and longer than its height. The titanium mesh was inserted into the orbit under an endoscopic view. The authors then confirmed that the titanium mesh supported the orbital contents by pressing the eyeball and finished the operation. Immediately after surgery, CT results were evaluated. RESULTS: Postoperative CT scans confirmed that the titanium mesh was well-inserted and in the correct position. All patients were discharged without any complications. CONCLUSIONS: We obtained satisfactory results by inserting a titanium mesh with porous polyethylene into the orbit via the transnasal approach endoscopically.

Iatrogenic Arteriovenous Fistula after Ultrasonography-Guided Core Needle Biopsy for Breast Lesion

Ultrasonography-guided core needle biopsy has been standard of care for diagnosing suspicious breast lesion. The procedure is safe and has a low rate of complications. Most common complication might be bleeding or hematoma, which could be avoided by careful process or changing it to excisional biopsy or managed by proper management. Rarely, Post-procedural arteriovenous fistula is reported in almost all body fields, which is life quality threatening, not life-threatening. Most of them occur with obvious vessel injury, and their primary end-point of management is the obliteration of fistula by thrombosis. However, we experienced a case of iatrogenic arteriovenous fistula after core needle biopsy for breast lesion with small vessel injury which was not but small ones, and its thrill did not disappear even after thrombosis. We would like to share our clinical learnings from surgical management process of this rare complication.

Surgery for Small Breast Cancer Considering Functional and Cosmetic Aspect / 한국유방암학회지

Sentinel Node Biopsy (SNB) is beneficial for reducing axillary functional impairment and lymphedema due to extended lymph node dissection. We used the Indigo Carmine dye instead of radioisotope, since it can simplify the complicated multistep identifying procedures and has economic benefit because it requires no radioisotope detection equipment. The operation for small breast cancer is continuously changing from a modified radical mastectomy to various type of breast conserving operations. Among these we performed a partial mastectomy with rotation flap using remnant breast tissue (RFB). This method needs small operation field, so we could reduce trauma to the patient, shorten the operation time, and use natural blood supplies and tissues without destructing other organ structures. The cosmetic effect is desirable to Korean women considering their relatively small breast size as to that of western people. In SNB, 5cc indigocarmine was injected intradermally just around main lesion. Sentinel node was able to be identified easily if a proper dose was used. Its approach was achieved in 15 to 20 minutes. Partial mastectomy (quadrantectomy) was done with cancer free margins. Rotation flap which is covering the defect included as much breast tissue as possible sparing the nipple areolar complex. Sentinel node biopsy and rotation flap brought out both satisfactory cosmetic result and cost effective outcome, so this breast conserving method is recommendable to small breast cancers.
