Compressive femoral neuropathy is a disabling condition accompanied by difficulty in hip flexion and knee extension. It may result from retroperitoneal hematoma or bleeding, or from complications associated with pelvic, hip surgery, and renal transplants. A 55-year-old female with autosomal dominant polycystic kidney disease presented with proximal muscle weakness in lower extremities. The patient experienced recurrent renal cyst infection, with aggravated weakness during each event. Electromyography and nerve conduction study revealed bilateral femoral neuropathy. Computed tomography and magnetic resonance images were added to further identify the cause. As a result, a diagnosis of femoral neuropathy caused by enlarged polycystic kidney was made. Cyst infection was managed with antibiotics. Renal function was maintained by frequent regular hemodialysis. While avoiding activities that may increase abdominal pressure, rehabilitation exercises were provided. Motor strength in hip flexion and knee extension improved, and was confirmed via electrodiagnostic studies.

Objective:
To investigate the epidemiologic and demographic characteristics of patients with spinal cord injury (SCI) who were admitted to a department of rehabilitation of a university hospital.
Methods:
This was a descriptive cross-sectional study. Medical records including sex, age at injury, type of disability, traumatic or non-traumatic etiology and presence of ossification of posterior longitudinal ligament (OPLL) of patients with SCI who were admitted to the department of rehabilitation between 2012 and 2018 were reviewed.
Results:
Of the 221 cases of SCI, 161 were traumatic and 60 were non-traumatic. The mean age at injury was 52.8 years. People aged 40–49 years showed highest proportion among overall SCI patients (19.0%). The proportion of male patients was higher in traumatic SCI at 4.96:1 than in non-traumatic SCI at 1.30:1. The most common cause of traumatic SCI was falling off (37.3%), followed by motor vehicle crash (35.4%) and tripping over (19.3%). Meanwhile, the most common cause of non-traumatic SCI was neoplasm (35.0%). Tripping over was the leading cause of traumatic SCI in patients aged ≥60 years (42.6%). A high proportion of traumatic SCI patients were found to have underlying OPLL (26.1%), particularly those who were injured by tripping over (64.5%).
Conclusion
The mean age of SCI patients was higher than that of previous studies. Falls was the single most common cause of traumatic SCI, and tripping over was the most common cause of injury in the elderly patients. OPLL was prevalent in patients who were injured from tripping over.

Cardiac arrhythmia is a rare manifestation of the Wallenberg syndrome; lesions are located in the brainstem, especially the lower medulla, which regulates sympathetic and parasympathetic activity. A 55-year-old man was admitted to the university hospital with symptoms including ataxia, left ptosis, decreased sensation of pain and temperature on the right side, left facial numbness, and dizziness. Brain magnetic resonance imaging revealed an infarction in the left dorsolateral medulla. Therefore, he was diagnosed with Wallenberg syndrome. While he underwent conservative treatment for Wallenberg syndrome, he experienced several events of self-limiting heart pounding, which required an evaluation of cardiac function. The 24-hour Holter monitor showed an increased RR interval with bradycardia and prolonged sinus pause. As a result, the diagnosis of sick sinus syndrome combined with Wallenberg syndrome was made. Sick sinus syndrome is a rare cardiac complication of the Wallenberg syndrome, and clinicians could overlook it when the initial electrocardiography shows a normal sinus rhythm. Sick sinus syndrome can cause sudden death without appropriate medical intervention. Therefore, clinicians should consider further evaluation, including a 24-hour Holter monitor, to check for the potential presence of sick sinus syndrome in the acute phase of Wallenberg syndrome.

Objective:
Shoulder pain is a common post-mastectomy complication. This research aims to evaluate the role of shoulder structure changes in developing shoulder pain in post-mastectomy patients and determine ultrasonographic findings.
Methods:
Medical records of post-mastectomy patients with ipsilateral shoulder pain were reviewed. Ultrasonographic findings, visual analogue scale (VAS), Shoulder Pain and Disability Index (SPADI), age, body mass index, time from mastectomy, operation type, lymph node dissection type, presence of lymphedema, and radiation therapy were checked.
Results:
Of 40 patients, rotator cuff tear, subacromial-subdeltoid bursitis, calcific tendinitis, biceps brachii tendon sheath fluid accumulation, and tendinopathy were seen in ultrasonography. Age was statistically higher in the rotator cuff tear group than non-rotator cuff tear group. Time from mastectomy, VAS, and SPADI were statistically correlated with biceps brachii sheath fluid accumulation. Shoulders with tendinopathy developed pain shortly after surgery. VAS and SPADI were statistically correlated with presence of subscapularis or supraspinatus tendinopathy. Nine of thirteen patients (69.2%) with subscapularis tendinopathy had post-mastectomy lymphedema. Only two of fifteen (18.2%) patients with supraspinatus tendinopathy had a history of radiation therapy.
Conclusion
Shoulder pain and rotator cuff tendinopathy may occur soon after surgery; therefore, shoulder range of motion exercises and muscle strengthening exercises are necessary in the early days after surgery. Elderly patients have a risk of rotator cuff tear, which physicians should pay more attention to. Even though there is no history of lymphedema and radiation therapy, shoulder lesions may occur. Therefore, prevention of shoulder pain in all patients after breast cancer surgery is needed.

PURPOSE: Circular stapled hemorrhoidopexy (CSH) is widely used to treat patients with grades III–IV hemorrhoids because of less pain and short hospital stay. However, this procedure is associated with some complications, such as urge to defecate, anal stenosis, staple line dehiscence, abscess and sepsis. To avoid these complications, surgeons perform a partial stapled hemorrhoidopexy (PSH). The aim of this study is to present our early experience with the PSH. METHODS: We retrospectively reviewed the medical records of 58 patients with hemorrhoids who were treated with a PSH at Busan Hang-Un Hospital from January 2016 to June 2016. A specially designed tri-window anoscope was used, and a purse string suture was made at the mucosae of the protruding hemorrhoids through the window of the anoscope. The hemorrhoidopexy was done by using a circular stapler. RESULTS: Of the 58 patients included in this study, 34 were male and 24 were female patients (mean age, 50.4 years). The mean operation time was 12.4 minutes, and the mean postoperative hospital stay was 3.8 days. Three patients experienced bleeding (5.1%) 5 urinary retention (8.6%) and 5 skin tags (8.6%). Urge to defecate, tenesmus, abscess, rectovaginal fistula, anal stricture, incontinence, and recurrence did not occur. CONCLUSION: PSH is a minimally invasive, feasible, and safe technique for treating patients with grades III–IV hemorrhoids. A PSH, instead of a CSH, can be used to treat certain patients with hemorrhoids.

OBJECTIVE: To evaluate the long termeffect of custom-molded foot orthoses on foot pain and balance ability in children with symptomatic flexible flat feet after 1 year.METHOD: A total of 35 children over 6 year-old with flexible flat feet and foot pain for at least 6 months were recruited. Individual custom-molded rigid foot orthoses fabricated with the inverted orthotic technique was prescribed. Pain related parameters (pain sites, degree, and frequency) were obtained through questionnaires. Pain assessment was performed prior to application of the foot orthoses, and 1, 3, 6, 12 months after applying the orthoses. Balance ability was tested by computerized posturography. Such measures were evaluated prior to, 3 months, and 12 months after applying the foot orthoses. Additionally, the difference inbalance ability between barefoot and withfoot orthosesat 12 months was assessed to estimate carryover effect.RESULTS: 17 out of 35 children completed the study. Significant improvements were noted upto 12 months in pain parameters and balance ability. The carry over effect of the orthoses was confirmed.CONCLUSION: There were significant improvements offoot pain and balance ability in children with symptomatic flexible flat foot after wearing foot orthoses fabricated with the inverted orthotic technique over 1year period.

BACKGROUND: Sugammadex is a novel neuromuscular reversal agent, but its associated hypersensitivity reaction and high cost have been obstacles to its widespread use. In the interest of reducing the necessary dosage of sugammadex, the reversal time of the combined use of sugammadex and neostigmine from moderate neuromuscular blockade were investigated. METHODS: The patients enrolled ranged in age from 18 to 65 years old with American Society of Anesthesiologists class 1 or 2. The subjects were randomly assigned into one of the four groups (Group S2, S1, SN, and N; n = 30 per group). The reversal agents of each groups were as follows: S2 - sugammadex 2 mg/kg, S1 - sugammadex 1 mg/kg, SN - sugammadex 1 mg/kg + neostigmine 50 microg/kg + glycopyrrolate 10 microg/kg, N - neostigmine 50 microg/kg + glycopyrrolate 10 microg/kg. The time to recovery of the train-of-four (TOF) ratio was checked in each group. RESULTS: The time to 90% recovery of TOF ratio was 182.6 +/- 88.9, 371.1 +/- 210.4, 204.3 +/- 103.2, 953.2 +/- 379.7 sec in group S2, S1, SN and N, respectively. Group SN showed a significantly shorter recovery time than did group S1 and N (P < 0.001). However, statistically significant differences between the S2 and SN groups were not be observed (P = 0.291). No hypersensitivity reactions occurred in all groups. CONCLUSIONS: For the reversal from rocuronium-induced moderate neuromuscular blockade, the combined use of sugammadex and neostigmine may be helpful to decrease the recovery time and can also reduce the required dosage of sugammadex. However, the increased incidence of systemic muscarinic side effects must be considered.

PURPOSE: The most common risk factor for fecal incontinence (FI) is obstetric injury. FI affects 1.4%–18% of adults. Most patients are unaware when they are young, when symptoms appear suddenly and worsen with aging. Autologous fat graft is widely used in cosmetic surgical field and may substitute for injectable bulky agents in treating FI. Authors have done fat graft for past several years. This article reports the effectiveness of the fat graft in treating FI and discusses satisfaction with the procedure. METHODS: Fat was harvested from both lateral thighs using 10-mL Luer-loc syringe. Pure fat was extracted from harvests and mixed with fat, oil, and tumescent through refinement. Fats were injected into upper border of posterior ano-rectal ring, submucosa of anal canal and intersphincteric space. Thirty-five patients with FI were treated with this method from July 2016 to February 2017 in Busan Hangun Hospital. They were 13 male (mean age, 60.8 years) and 22 female patients (mean age, 63.3 years). The Wexner score was checked before procedure. We evaluated outcome in outpatients by asking the patients. For 19 patients we checked the Wexner score after procedure. RESULTS: Symptom improved in 29 (82.9%), and not improved in 6 (17.1%). In 2 of 6 patients, they felt better than before procedure, although not satisfied. No improvement in 4. Mean Wexner score was 9.7 before procedure. There were no serious complications such as inflammation or fat embolism. CONCLUSION: Autologous fat graft can be an effective alternative treatment for FI. It is safe and easy to perform, and cost effective.

Purpose:
The objective of this study was to propose a deep-learning model for the detection of the mandibular canal on dental panoramic radiographs.
Materials and Methods:
A total of 2,100 panoramic radiographs (PANs) were collected from 3 different machines: RAYSCAN Alpha (n=700, PAN A), OP-100 (n=700, PAN B), and CS8100 (n=700, PAN C). Initially, an oral and maxillofacial radiologist coarsely annotated the mandibular canals. For deep learning analysis, convolutional neural networks (CNNs) utilizing U-Net architecture were employed for automated canal segmentation. Seven independent networks were trained using training sets representing all possible combinations of the 3 groups. These networks were then assessed using a hold-out test dataset.
Results:
Among the 7 networks evaluated, the network trained with all 3 available groups achieved an average precision of 90.6%, a recall of 87.4%, and a Dice similarity coefficient (DSC) of 88.9%. The 3 networks trained using each of the 3 possible 2-group combinations also demonstrated reliable performance for mandibular canal segmentation, as follows: 1) PAN A and B exhibited a mean DSC of 87.9%, 2) PAN A and C displayed a mean DSC of 87.8%, and 3) PAN B and C demonstrated a mean DSC of 88.4%.
Conclusion
This multi-device study indicated that the examined CNN-based deep learning approach can achieve excellent canal segmentation performance, with a DSC exceeding 88%. Furthermore, the study highlighted the importance of considering the characteristics of panoramic radiographs when developing a robust deep-learning network, rather than depending solely on the size of the dataset.
