The authors report a case of primary breast lymphoma in a 29-year-old female patient. The patient had a growing, nontender, palpable mass in the left breast. Film-screen mammogram showed a sharply marginated mass with a thin perimeter of radiolucency, halo and slight lobulation.Sonography revealed a well marginated hypoechoic mass with posterior acoustic enhancement. The patient had undergone wide excision of mass and ipsilateral axillary dissection. Histologic examination and immuno-histochemistry confirmed a diagnosis of diffuse B-cell type non-Hodgkin's lymphoma. Abdominal ultrasonography, thoracic computed tomography and bone scan, checked postoperatively, showed non-specific findings. We concluded a final diagnosis of primary breast lymphoma, and report the case with a brief review of the literatures.

BACKGROUND: The objective of this article is to evaluate clinical outcomes of combined orbital floor and medial wall fracture repair using a three-dimensional pre-bent titanium implant in an East Asian population. METHODS: Clinical and radiologic data were analyzed for 11 patients with concomitant orbital floor and medial wall fractures. A combined transcaruncular and inferior fornix approach with lateral canthotomy was used for the exposure of fractures. An appropriate three-dimensional preformed titanium implant was selected and inserted according to the characteristics of a given defect. RESULTS: Follow-up time ranged from 2 to 6 months (median, 4.07 months). All patients had a successful treatment outcome without any complications. Clinically significant enophthalmos was not observed after treatment. CONCLUSIONS: Three-dimensional pre-bent titanium implants are appropriate for use in the East Asian population, with a high success rate of anatomic restoration of the orbital volume and prevention of enophthalmos in combined orbital floor and medial wall fracture cases.

PURPOSE: There have been few case reports regarding treatment plans for long-term, neglected scalp defects and calvarial defects with subdural abscess. The purpose of this case report is to present our experience with a free latissimus dorsi musculocutaneous flap for scalp and calvarial defects and to discuss flap options in comparison with a literature review. METHODS: A 60-year-old man who fell down from a four-story-height that resulted in a craniotomy in 1979; he visited our outpatient clinic for a chronic, purulent scalp and calvarial defects with unidentified artificial bone. The artificial bone was removed by a neurosurgeon and reconstructed with a free latissimus dorsi musculocutaneous flap. The deep temporal artery was used as a recipient artery. The postoperative flap status was excellent until the 6th day post-operation when the patient experienced a seizure, and an arterial insufficiency occurred at the flap probably due to an arterial spasm. Emergency exploration with arterial re-anastomosis was performed and the flap status was stabilized. RESULTS: Complete wound healing was achieved after 3 weeks without infectious and systemic postoperative complications. During the 6 month follow-up period, there were no complications. CONCLUSION: We suggest the latissimus dorsi myocutaneous free flap as a good treatment option for a chronic, purulent, complicated scalp with calvarial defect, as a well as treatment for an acute traumatic defect.

PURPOSE: Dermatofibrosarcoma protuberans is a relatively rare tumor that originates from the dermis and subcutaneous tissue. It is generally known that this tumor easily recurs but can be successfully treated with a wide excision. Therefore, this study was conducted to investigate postoperative outcomes and risk factors for recurrence in patients with dermatofibrosarcoma protuberans who were treated at a single institution for 20 years. METHODS: We retrospectively reviewed the medical records of 35 patients who had underwent surgery between June 1992, and September 2010. The patients were assessed in terms of predilection site and size of the tumor, the incidence according to sex, discrepancy between biopsy results and histopathological diagnosis of the surgical specimen, additional treatment after recurrence, recurrence rate and the time interval to recurrence. RESULTS: In multivariate analysis, the depth and site of the tumor were significant risk factors for tumor recurrence. The recurrence rate was significantly higher in tumors occurring in the upper extremity than those occurring in other regions(p=0.0348). In addition, the recurrence rate was significantly higher in tumors with involvement of the fascia and the deeper structures(p=0.0324, odds ratio=6, relative risk=1.588). Since dermatofibrosarcoma protuberans has strong invasiveness, its tissue involvement is difficult to evaluate accurately. CONCLUSION: The results of this study shows that involvement of the fascia and the deeper structures and occurrence in the upper extremity were associated with tumor recurrence. Therefore, clinicians should be aware of these risk factors to achieve better treatment outcomes.

Electroconvulsive therapy (ECT) is indicated for various mental disorders (e.g., major depressive disorder, schizophrenia, and bipolar disorder) and the behavioral and psychological symptoms of dementia in elderly patients. Furthermore, ECT is a useful first-line treatment in emergency and crisis situations such as suicide risk, violent behavior, catatonia, and food refusal, which are more frequent in elderly patients. ECT is also effective in the treatment of the motor symptoms of neurological disorders, such as Parkinson’s disease and Huntington’s disease. Due to the high risk of various physical diseases, the comorbid physical conditions of elderly patients should be individually controlled to optimize ECT treatment. Compared to young adults, in elderly patients the seizure threshold is higher, the seizure duration is shorter, and the anesthetic dose is lower. On the contrary, the response rate in the elderly is both faster and higher. Considering potential cognitive decline and the prevention of further deterioration of cognitive function in elderly patients, in the absence of significant comorbidities, twice weekly sessions and right unilateral electrode placement with a lower seizure threshold and less cognitive effect are preferred to bilateral electrode placement, which has a high risk of adverse cognitive effects. After an acute course of ECT, continuation and maintenance of ECT, combined with prescription of therapeutic drugs, may prevent possible relapse or recurrence of mental disorders. In conclusion, ECT can be used to treat mental disorders in elderly adults, with safety and effectiveness comparable to that in young adults.

Pulmonary cryptococcosis is a non-infectious opportunistic or silent infection caused by Cryptococcus neoformans. It enters the body through the respiratory tract and spreads to lung, skin, liver, and lymphoid organs. Recently its incidence has been gradually increasing because of developing diagnostic tools, increased use of steroids and immunosuppressive drugs, increased survival rate of patients with chronic diseases, and increased incidence of immunodeficiency syndrome. We report a case of pulmonary cryptococcosis in a patient with rheumatoid arthritis who was being treated with low dose glucocorticoid, methotrexate and cyclosporine for 14 months.

Commotio cordis is induction of sudden cardiac arrest and ventricular fibrillation (VF) by chest blunt trauma and nonpenetrating injury without damage to the rib, sternum, and heart in a person without underlying cardiovascular disease. Commotio cordis has been rarely reported worldwide, and it is particularly rare in the case of traffic accident (TA). We experienced a case of commotio cordis in a healthy 20-year-old man who was involved in a TA. The patient had no other signs of trauma except blunt chest trauma, and the initial electrocardiography (ECG) rhythm checked by the emergency medical technician (EMT) team was VF. They performed defibrillation and cardiopulmonary resuscitation (CPR) during transfer. CPR including defibrillation was performed because VF continued upon arrival at the emergency department, and therapeutic hypothermia (THT) was performed because glasgow coma scale (GCS) score was 3 after return of spontaneous circulation (ROSC). The patient's mental status became alert after performance of THT and cerebral performance category (CPC) score was 1 without neurological symptoms at the time of discharge. In trauma patients who may be have blunt chest trauma, including TA, emergency medical service providers must perform continuous monitoring with commotio cordis in mind, and perform defibrillation and CPR immediately if VF arises. With training in basic CPR and a supply of automated external defibrillators (AED) for application to trauma patients, the survival rate of commotio cordis patients can be increased.

OBJECTIVES: In order to search for new parameters for the evaluation of the adequacy of electroconvulsive therapy (ECT) the authors performed a non-linear analysis of electroencepha-logram(EEG)recorded during the course of electroconvulsive therapy(ECT)in a single female patient with depression. METHODS: Digitized EEG recordings from two ECT sessions spaced one week were analyzed at five different stages; pretreatment stable, postanesthetic-preictal, ictal, postictal suppression and posttreatment stable stages. RESULTS: Our analysis showed that 1)EEG signals had low dimensional (below 10 dimensions) deterministic characteristics 2) although EEG was nonstationary signal, non-linear parameters could reliably differentiate between various stages we examined. 3)the deterministic property of ictal EEG increased according to the progression of sessions and 4)the primary Lyapunov exponent(PLE)and correlation dimension of pre- and post-treatment stable stage EEG increased according to the progression of sessions. CONCLUSION: In this single case study, results of various non-linear analyses suggested that non-linear variables extracted from EEG recordings during ECT may have utilities as tools for the quantitative evaluation of ECT.

Infective endocarditis is a life-threatening condition caused by microbial infection of the heart's endocardial surface. This condition can also be associated with bacterial infections of other organs. We experienced an unusual case of recurrent infective endocarditis associated with pyogenic spondylodiskitis. A 70-year-old man presented with persistent fever and lower back pain visited our hospital. The patient had a past history of recurrent infective endocarditis. He was diagnosed with infective endocarditis again based on clinical symptoms and echocardiographic findings. Magnetic resonance imaging was used to evaluate lower back pain, which showed acute spondylodiskitis on L3 and L4 vertebrae. The patient completely recovered following four weeks of antibiotic therapy.
