Long-term Prognosis of Localized Lymphoid Hyperplasia of the Rectum

Background/Aims@#Although localized lymphoid hyperplasia (LLH) of the rectum is occasionally observed, its clinical implications are unclear. This study aimed to investigate the clinical course and significance of LLH of the rectum. @*Methods@#We identified 65 patients diagnosed with LLH of the rectum using a histopathologic examination and who received follow-up endoscopies between January 2009 and June 2015. Patients with a history of inflammatory bowel disease, lymphoma, familial adenomatous polyposis, or uncontrolled malignancy and patients who underwent scar biopsy after endoscopic resection or surgery were excluded. Endoscopic findings and clinical courses were analyzed. @*Results@#During the median follow-up of 31 months (interquartile range, 19 to 40 months), 81.5% (53/65) of LLHs of the rectum were resolved. Clinically significant diseases, including ulcerative colitis (UC, n=5) and mucosa-associated lymphoid tissue (MALT) lymphoma (n=1), were diagnosed in 9.2% of patients (6/65). The other six patients showed no significant changes in the lesion (n=3) or a waxing and waning appearance (n=3). According to endoscopic findings, all of the 47 polypoid types showed resolution or waxing and waning patterns. Five of the 11 nodular types (45.5%) developed into UC. One of the seven submucosal tumor (SMT)-like types (14.3%) developed into MALT lymphoma. @*Conclusions@#LLH of the rectum with persistent symptoms or the endoscopic appearance of the nodular or SMT-like type may lead to clinically significant disease. Risk stratification according to endoscopic findings and careful surveillance are required for these lesions.

The Usefulness of the Two-Staged Pedicled Latissimus Dorsi (LD) Flap in Fourth-Degree Burns of Upper Extremity

Purpose@#A large defect by fourth-degree burns in the upper limb requires flap reconstruction. Since severe vascular damage and decrease in blood circulation after vascular anastomosis can occur in defects caused by fourth-degree burns. Because of the disadvantages, it is difficult to apply free flap surgery to fourth-degree burns. We reconstructed a upper extremity using the pedicled Latissimus Dorsi (LD) flap in two stages. The purpose of our study is to review our experience and suggest two-staged pedicled Latissimus Dorsi (LD) flap in fourth-degree burns of upper extremities. @*Methods@#A retrospective review was performed from 2016 to 2019, on a total of 12 fourth-degree burn patients undergone two-staged pedicled LD flap surgery as reconstruction of upper extremities in our hospital. We reviewed the location of the injury, etiology, TBSA (%), size of burns requiring flap surgery, period from 1st surgery to secondary division surgery, complications. @*Results@#Using two-staged LD flap as a primary reconstruction, the outcome is satisfactory. This flap preserves the elbow joint and maintains the length of the forearm. We obtain low donor-site morbidity, simplicity and a small incision in the donor site. @*Conclusion@#Using two-staged LD flap in fourth-degree burns of upper extremity is effective, such as preserving elbow joint and maintaining the length of the forearm. Successful reconstruction was achieved with excellent cosmetic results with reducing a postoperative scar, donor-site morbidity. Due to these advantages, two-staged pedicled LD flap can be an optimal option for reconstruction of fourth-degree burns in the upper limb.

Early cicatricial lagophthalmos release with pentagonal wedge resection of the scar, fat redistribution, and full-thickness skin grafting

The specialized structure of the upper eyelid ensures complete closure of the eye and eyeball sealing. An upper eyelid injury can cause various symptoms associated with eyeball trauma, not just scar formation or eyelid deformity. In this report, we describe a case of lagophthalmos observed after wound repair in a patient with a crushing injury caused by a grinder. Several surgical techniques are used to treat lagophthalmos or scar contracture. In most cases, a releasing procedure is performed after 6 months of initial repair. However, if the patient has severe symptoms that are not relieved by conservative care, early revision is inevitable. We describe a case of early lagophthalmos successfully resolved with pentagonal wedge resection, fat redistribution, and full-thickness skin grafting. After the revisional surgery, we observed that the patient regained the ability to completely close the injured eyelid, with restoration of function and favorable cosmetic outcomes. Pentagonal wedge resection to release a retracted structure, fat redistribution to prevent readhesion, and full-thickness skin grafting for enough amount of skin to regain upper eyelid function is useful for scar release and lagophthalmos following crushing injuries of the upper eyelid.

Early management of parotid gland injury with oral nortriptyline and closed drain

Parotid gland plays the most critical role in saliva secretion in the oral cavity. Parotid gland injuries due to facial trauma can cause various complications such as formation of a fistula or sialocele. Thus, such saliva-related complications can interfere with wound healing and increase the risk of infection. Several previous studies have discussed the treatment of fistula or sialocele. Nonetheless, prevention of such complications is of utmost importance. We present a case of parotid gland injury due to trauma to the cheeks that was surgically treated, with early postoperative management involving oral administration of nortriptyline and closed drainage, without complications.

Skin malignancy initially misdiagnosed as a benignepidermal cyst

Skin cancer, which often occurs as a result of skin exposure to ultraviolet light radiation, usuallypresents with characteristic abnormal features, such as ulcerative lesions, irregular morphology,bleeding, and excessive growth. Therefore, skin cancer rarely resembles a benign tumor on visualinspection. Nonetheless, squamous cell carcinoma and basal cell carcinoma with nodular or polypoidfeatures can have a similar appearance to that of benign tumors, meaning that they aresometimes misdiagnosed as benign. As benign and malignant tumors have some overlappingfeatures, clinicians sometimes use additional imaging techniques such as ultrasonography to improvethe accuracy of the diagnosis because even a malignant tumor that externally resembles abenign tumor generally has internal morphological features characteristic of malignancy, such asinvasion and irregular borders. However, these imaging tools also have limitations, and punch orexcisional biopsy can be needed if malignancy cannot be completely ruled out. Herein, we reporta case of skin malignancy initially misdiagnosed as a benign epidermal cyst based on external visualinspection and ultrasonography.

A retrospective computed tomography analysis of maxillary fractures and the clinical outcomes of their unreduced parts

BACKGROUND: Some parts of a maxillary fracture—for example, the medial and posterior walls—may remain unreduced because they are unapproachable or hard to deal with. This study aimed to investigate the self-healing process of unreduced maxillary membranous parts of fractures through a longitudinal computed tomography (CT) analysis of cases of unilateral facial bone injuries involving the maxillary sinus walls.METHODS: Thirty-two patients who had undergone unilateral facial bone reduction surgery involving the maxillary sinus walls without reduction of the medial and posterior walls were analyzed in this retrospective chart review. Preoperative, immediate postoperative, and 3-month postoperative CT scans were analyzed. The maxillary sinus volume was calculated and improvements in bone continuity and alignment were evaluated.RESULTS: The volume of the traumatized maxillary sinuses increased after surgery, and expanded significantly by 3 months postoperatively (p< 0.05). The significant preoperative volume difference between the normal and traumatized sides (p= 0.024) resolved after surgery (p> 0.05), and this resolution was maintained at 3 months postoperatively (p > 0.05). The unreduced parts of the maxillary bone showed improved alignment and continuity (in 75.0% and 90.6% of cases, respectively), and improvements in bone alignment and bone continuity were found to be correlated using the Pearson chi-square test (p= 0.002).CONCLUSION: Maxillary wall remodeling through self-healing occurred concomitantly with an increase in sinus volume and simultaneous improvements in bone alignment and continuity. Midfacial surgeons should be aware of the natural course of unreduced fractured medial and posterior maxillary walls in complex maxillary fractures.

Congenital cutaneous pedicled macrocystic lymphatic malformation on the upper extremity: A rare case report and review of the literature

Congenital cystic lymphatic malformations on the extremities are very rare. The patient described in this case study presented with a cutaneous and pedicled macrocystic lymphatic malformation that was eliminated by electrocauterization. A 4-day-old female infant with a congenital cutaneous mass on the dorsal area of her left first metacarpophalangeal joint presented to an outpatient clinic. An electrocautery device was used to cut the pedicle gently with minimal bleeding to avoid mass rupture and to minimize morbidity. A simple wet dressing was applied for 1 week, and the wound subsequently healed completely. Cutaneous macrocystic lymphatic malformations are very rare, especially on the extremities, and no consensus exists on their treatment, which has not been previously described. This report presents this rare case, along with a review of the literature.

Assessment of Quality of Life and Safety in Postmenopausal Breast Cancer Patients Receiving Letrozole as an Early Adjuvant Treatment / 한국유방암학회지

PURPOSE: There are few reports from Asian countries about the long-term results of aromatase inhibitor adjuvant treatment for breast cancer. This observational study aimed to evaluate the long-term effects of letrozole in postmenopausal Korean women with operable breast cancer. METHODS: Self-reported quality of life (QoL) scores were serially assessed for 3 years during adjuvant letrozole treatment using the Korean version of the Functional Assessment of Cancer Therapy-Breast questionnaires (version 3). Changes in bone mineral density (BMD) and serum cholesterol levels were also examined. RESULTS: All 897 patients received the documented informed consent form and completed a baseline questionnaire before treatment. Adjuvant chemotherapy was administered to 684 (76.3%) subjects, and 410 (45.7%) and 396 (44.1%) patients had stage I and II breast cancer, respectively. Each patient completed questionnaires at 3, 6, 12, 18, 24, 30, and 36 months after enrollment. Of 897 patients, 749 (83.5%) completed the study. The dropout rate was 16.5%. The serial trial outcome index, the sum of the physical and functional well-being subscales, increased gradually and significantly from baseline during letrozole treatment (p<0.001). The mean serum cholesterol level increased significantly from 199 to 205 after 36 months (p=0.042). The mean BMD significantly decreased from −0.39 at baseline to −0.87 after 36 months (p<0.001). CONCLUSION: QoL gradually improved during letrozole treatment. BMD and serum cholesterol level changes were similar to those in Western countries, indicating that adjuvant letrozole treatment is well tolerated in Korean women, with minimal ethnic variation.

Pedicled Anterolateral Thigh Flaps for Reconstruction of Recurrent Trochanteric Pressure Ulcer

The reconstruction of recurrent pressure sores is challenging due to a limited set of treatment options and a high risk of flap loss. Successful treatment requires scrupulous surgical planning and a multidisciplinary approach. Although the tensor fascia lata flap is regarded as the standard treatment of choice-it provides sufficient tissue bulk for a deep trochanteric sore defect-plastic surgeons must always consider the potential of recurrence and accordingly save the second-best tissues. With the various applications of anterolateral thigh (ALT) flaps in the reconstructive field, we report two cases wherein an alternative technique was applied, whereby pedicled ALT fasciocutaneous island flaps were used to cover recurrent trochanteric pressure sores. The postoperative course was uneventful without any complications. The flap provided a sound aesthetic result without causing a dog-ear formation or damaging the lower-leg contour. This flap was used as an alternative to myocutaneous flaps, as it can cover a large trochanteric defect, recurrence is minimized, and the local musculature and lower-leg contour are preserved.

Glomus Tumor of the Hand

BACKGROUND: Glomus tumors were first described by Wood in 1812 as painful subcutaneous tubercles. It is an uncommon benign neoplasm involving the glomus body, an apparatus that involves in thermoregulation of cutaneous microvasculature. Glomus tumor constitutes 1%-5% of all hand tumors. It usually occurs at the subungual region and more commonly in aged women. Its classical clinical triad consists of pain, tenderness and temperature intolerance, especially cold sensitivity. This study reviews 15 cases of glomus tumor which were analyzed according to its anatomic location, surgical approach and histologic findings. METHODS: Fifteen patients with subungual glomus tumors of the hand operated on between January 2006 and March 2013, were retrospectively reviewed. Patients were evaluated preoperatively with standard physical examination including ice cube test and Love's test. Diagnostic imaging consisted of ultrasonography, computed tomography, and magnetic resonance imaging. All procedures were performed with tourniquet control under local anesthesia. Eleven patients underwent excision using the transungual approach, 3 patients using the volar approach and 1 patient using the lateral subperiosteal approach. RESULTS: Total of 15 cases were reviewed. 11 tumors were located in the nail bed, 3 in the volar pulp and 1 in the radial aspect of the finger tip. After complete excision, patients remained asymptomatic in the immediate postoperative period. In the long term follow up, patients exhibited excellent cosmetic results with no recurrence. CONCLUSIONS: Accurate diagnosis should be made by physical, radiologic and pathologic examinations. Preoperative localization and complete extirpation is essential in preventing recurrence and subsequent nail deformity.

Pollicization of the Middle Finger

PURPOSE: Pollicization typically involves surgical migration of the index finger to the position of the thumb. This procedure facilitates the conversion of a useless hand into a well-functioning one in patients who are not amenable to the toe-to-hand transfer. However, middle finger pollicization has been rarely reported. MATERIALS AND METHODS: We reconstructed a thumb by immediate pollicization of the remnants of the middle finger in two patients who sustained a tumor and a trauma, respectively. The former, after cancer ablation was performed, has not been reported literally, and the latter involved free devitalized pollicization of the middle finger using a microsurgical anastomosis. The distal third extensor communis tendon was sutured to the proximal extensor pollicis longus tendon and the distal flexor digitorum superficialis and profundus were sutured to the proximal flexor pollicis longus. The abductor pollicis brevis tendon was sutured to the distal end of the first palmar interosseous muscle. Coaptation of the third digital nerve and the superficial radial nerve branch was performed. RESULTS: Patients showed uneventful postoperative courses without complication such as infection or finger necrosis. Based on the principles of pollicization, a wide range of pinch and grasp movements was successfully restored. They were pleased with the functional and cosmetic results. CONCLUSIONS: Although the index finger has been the digit of choice for pollicization, we could also use the middle finger on specific occasions. This procedure provides an excellent option for the reconstruction of a mutilated thumb and could be performed advantageously in a single step.

Stent Compression in Iliac Vein Compression Syndrome Associated with Acute Ilio-Femoral Deep Vein Thrombosis

OBJECTIVE: This study was conducted to evaluate stent compression in iliac vein compression syndrome (IVCS) and to identify its association with stent patency. MATERIALS AND METHODS: Between May 2005 and June 2014, after stent placement for the treatment of IVCS with acute ilio-femoral deep vein thrombosis, follow-up CT venography was performed in 48 patients (35 women, 13 men; age range 23-87 years; median age 56 years). Using follow-up CT venography, the degree of the stent compression was calculated and used to divide patients into two groups. Possible factors associated with stent compression and patency were evaluated. The cumulative degree of stent compression and patency rate were analyzed. RESULTS: All of the stents used were laser-cut nitinol stents. The proportion of limbs showing significant stent compression was 33%. Fifty-six percent of limbs in the significant stent compression group developed stent occlusion. On the other hand, only 9% of limbs in the insignificant stent compression group developed stent occlusion. Significant stent compression was inversely correlated with stent patency (p < 0.001). The median patency period evaluated with Kaplan-Meier analysis was 20.0 months for patients with significant stent compression. Other factors including gender, age, and type of stent were not correlated with stent patency. Significant stent compression occurred most frequently (87.5%) at the upper end of the stent (ilio-caval junction). CONCLUSION: Significant compression of nitinol stents placed in IVCS highly affects stent patency. Therefore, in order to prevent stent compression in IVCS, nitinol stents with higher radial resistive force may be required.

Four Flaps Technique for Neoumbilicoplasty

The absence or disfigurement of the umbilicus is both cosmetically and psychologically distressing to patients. The goal of aesthetically pleasing umbilical reconstruction is to create a neoumbilicus with sufficient depth and good morphology, with natural-looking superior hooding and minimal scarring. Although many reports have presented techniques for creating new and attractive umbilici, we developed a technique that we term the "four flaps technique" for creating a neoumbilicus in circumstances such as the congenital absence of the umbilicus or the lack of remaining umbilical tissue following the excision of a hypertrophic or scarred umbilicus. This method uses the neighboring tissue by simply elevating four flaps and can yield sufficient depth and an aesthetically pleasing shape with appropriate superior hooding.

Anti-Inflammatory Effect of Violapyrones B and C from a Marine-derived Streptomyces sp

Recently, we reported violapyrones B, C, H and I, unusual 3, 4, 6-trisubstituted alpha-pyrone derivatives, from the culture broth of the marine Streptomyces sp. 112CH148. In previous studies, violapyrones have been shown to have antibacterial and antitumor activities. However, the anti-inflammatory effect of violapyrones has not been reported yet. As part of our ongoing study for the discovery of bioactive metabolites from marine microorganisms, we found that violapyrones also have anti-inflammatory activity. In this study, we investigated the effect of violapyrones on LPS-induced inflammatory responses in vitro. Violapyrones B and C did not affect the viability of RAW 264.7 cells at concentrations up to 25 microM. However, violapyrones B and C inhibited the production of NO compared to the LPS-induced control. In addition, violapyrones B and C down-regulated the expression of iNOS protein in LPS-stimulated RAW 264.7 cells. To the best of our knowledge, this is the first report on the anti-inflammatory activity of violapyrones B and C.

Diagnosing Micro Foreign Bodies with the Microscope

The microscope is a surgical instrument with wide use in plastic surgeries more often than other departments due to the high rate of microscopic surgeries. Unfortunately, because the microscope is used mainly for digital replantations and free flaps, the utilization rate is low compared to the price and usability of the microscope itself. From September 2013 to March 2014, a foreign body which was untraceable with radiology in a patient who desired surgical exploration (one case), and a foreign body which was detected but was smaller than 3 mm (two cases) were removed using the microscope. All foreign bodies, which were fish bone, thin metals, or wooden objects, matching the history of the patients, were completely removed without damage. There were no complications and patient satisfaction was high through follow-up. We have described the microscope as the last and optimal examination tool in removal of micro foreign bodies. A simple change of thought, so that the microscope can be used as a second diagnostic tool will decrease complications by foreign bodies.

Intratendinous Ganglion of the Extensor Digitorum Tendon

Ganglion cyst is the most common benign tumor arising from the hand and wrist. Rarely, they are found within the tendon. To date, only 10 cases in English papers and 7 cases in domestic papers on ganglion cysts in extensor digitorum tendons have been reported. Due to the rarity of this entity, it is difficult to suspect intratendinous ganglion fully based on the physical examination. Accordingly, preoperative studies such as ultrasonography, magnetic resonance imaging are recommended when suspicious result is revealed on the physical examination. Treatment should include en bloc resection of the affected tendon to reduce recurrence. But functional loss always has to be considered. This study reports two cases of intratendinous ganglion cysts that arised from the second and fourth extensor digitorum tendon.
