Paraffin injection has been widely used to improve body contouring or to augment various body parts, although it has now been abandoned owing to serious complications. Paraffin injection may lead to complications after a long latency period, ranging from several years to several decades. Here, we present the rare case of a 77-year-old woman who suffered from recurrent wound problems after a bilateral paraffin injection into her hands 40 years ago. Initially, conservative debridement was carried out due to the patient’s reluctance to undergo extensive surgery and cost concerns. However, this resulted in recurrent wound dehiscence and infection. After serial debridement procedures, a skin graft was performed on her right hand. The patient complained of a depressed contour and numbness at the skin graft site, and tightness and discomfort of her right hand during flexion of the metacarpophalangeal joint. Three years later, the patient presented with a highly similar wound on her left hand. Thorough excision of the soft tissue infiltrated by paraffin was performed, followed by reconstruction using a sensate free anterolateral thigh flap. The patient responded well postoperatively without complications, displaying a fair range of motion without discomfort, sensory restoration of the flap, and satisfaction with the contour of the dorsum. This case report highlights the importance of complete excision of soft tissues infiltrated by paraffin for definitive treatment. Among the various reconstruction options, a sensate free flap is a good choice for achieving favorable functional and esthetic outcomes in hand reconstruction after radical excision of a paraffinoma.

OBJECTIVE: Minimal data exist regarding non-operative management of suspected pseudarthrosis after pedicle subtraction osteotomy (PSO). This study reports radiographic and clinical outcomes of non-operative management for post-PSO pseudarthrosis at a minimum 5 years post-detection.METHODS: Nineteen consecutive patients with implant breakage indicating probable pseudarthrosis after PSO surgery (13 women/six men; mean age at surgery, 58 years) without severe pain and disability were treated with non-operative management (mean follow-up, 5.8 years; range, 5–10 years). Non-operative management included medication, intermittent brace wearing and avoidance of excessive back strain. Radiographic and clinical outcomes analysis was performed.RESULTS: Sagittal vertical axis (SVA), proximal junctional angle, thoracic kyphosis achieved by a PSO were maintained after detection of pseudarthrosis through ultimate follow-up. Lumbar lordosis and PSO angle decreased at final follow-up. There was no significant change in Oswestry Disability Index (ODI) scores and Scoliosis Research Society (SRS) total score, or subscales of pain, self-image, function, satisfaction and mental health between detection of pseudarthrosis and ultimate follow-up. SVA greater than 11 cm showed poorer ODI and SRS total score, as well as the pain, self-image, and function subscales (p<0.05).CONCLUSION: Non-operative management of implant failure of probable pseudarthrosis after PSO offers acceptable outcomes even at 5 years after detection of implant breakage, provided SVA is maintained. As SVA increased, outcome scores decreased in this patient population.

Müllerian duct aplasia-renal aplasia-cervicothoracic somite dysplasia (MURCS) association is a unique development disorder with four common types of malformations that include uterine aplasia or hypoplasia, renal ectopy or agenesis, vertebral anomalies, and short stature. The majority of MURCS patients are diagnosed with primary amenorrhea from late-adolescence. However, a few cases with MURCS association are not well diagnosed during childhood and long-term outcomes are not well reported. We report a case of an 8-year-old girl with MURCS association who presented with recurrent urinary tract infections and multiple congenital malformations, and who was followed for 10 years until adulthood. MURCS association should be considered as one of the differential diagnoses when evaluating prepubertal females with vertebral and renal malformations.

Endometriosis is one of the most common diseases in reproductive ages, and it affects patients' quality of life and fertility. However, few Korean guidelines are available for the evaluation and management of endometriosis. Korean Society of Endometriosis reviewed various literatures and trials, and to provide seventy-one evidence-based recommendations. This review presents guidelines for the diagnosis and management of endometriosis with emphasis on: it's role in infertility, treatment of recurrence, asymptomatic women, endometriosis in adolescents and menopausal women, and possible association of endometriosis with cancer.

Asian-lineage H5 highly pathogenic avian influenza (HPAI) viruses have caused continuous outbreaks in poultry and wild birds. Development of rapid and accurate diagnostic methods is needed for preventing further spread of the virus and reducing the time required for eradication of the virus. We developed a low-density microarray for the rapid detection and identification of avian influenza virus subtypes H5, H7, and H9 and their pathotypes in a previous study. In the present study, we evaluated previously developed diagnostic microarray using avian influenza viruses isolated in Mongolia, including H5 HPAI viruses. All H5 HPAI viruses isolated in Mongolia were shown as H5-specific and highly pathogenic pattern in the microarray. H2, H3 and H12 viruses isolated in Mongolia used in this study did not show any H5, H7 and H9 patterns. These results indicated that this diagnostic microarray has enormous potential for the rapid subtyping and pathotyping of influenza viruses, including viruses isolated in Mongolia.

OBJECTIVE: The objective of this study was to determine the correlations between changes in thrombogenesis or thrombolysis related factors, and the acute increase of a spontaneous intracerebral hemorrhage (sICH). MATERIALS AND METHODS: From January 2009 to October 2011, 225 patients with sICH were admitted to our hospital within 24 hours of onset. Among them, 111 patients with hypertensive sICH were enrolled in this study. Thrombogenic or thrombolytic factors were checked at admission. The authors checked computed tomography (CT) scans at admission and followed up the next day (between 12-24 hours) or at any time when neurologic signs were aggravated. Cases in which the hematoma was enlarged more than 33% were defined as Group A and the others were defined as Group B. RESULTS: Group A included 30 patients (27%) and group B included 81 patients (73%). Factors including activated partial thromboplastin time, prothrombin time, fibrinogen, and D-dimer showed a greater increase in group A than in group B. Factors including antithrombin III, factor V, and factor X showed a greater increase in group A than in group B. CONCLUSION: Based on the results of this study, it seems that the risk of increase in hematoma size can be predicted by serum thrombogenic or thrombolytic factors at admission.

BACKGROUND: Degenerative lumbar scoliosis (DLS) progresses with aging after 50-60 years, and the genetic association of DLS remains largely unclear. In this study, the genetic association between collagen type II alpha 1 (COL2A1) gene and DLS was investigated. METHODS: COL2A1 gene polymorphism was investigated in DLS subjects compared to healthy controls to investigate the possibility of its association with COL2A1 gene. Based on a single nucleotide polymorphism (SNP) database, SNP (rs2276454) in COL2A1 were selected and genotyped using direct sequencing in 51 patients with DLS and 235 healthy controls. The SNP effects were analyzed using three models of codominant, dominant, and recessive. Logistic regression models were calculated for odds ratios (ORs) with 95% confidence intervals (CIs) and corresponding p-values, controlling age and gender as co-variables. RESULTS: SNP (rs2276454) in COL2A1 was significantly associated with the degenerative lumbar scoliosis in the codominant (OR, 1.90; 95% CI, 1.17 to 3.10; p = 0.008) and dominant models (OR, 3.58; 95% CI, 1.59 to 9.29; p = 0.001). CONCLUSIONS: The results suggest that COL2A1 is associated with the risk of DLS in Korean population.

The blood blister-like aneurysm (BBA) of the internal carotid artery (ICA) is a rare but clinically important cause of subarachnoid hemorrhage (SAH), which accounts for 0.5% of incidences of ruptured intracranial aneurysms. BBA is a thin-walled, broad-based aneurysm that lacks an identifiable neck and is one of the most difficult lesions to treat. In this paper, a case is presented of a 57-year-old woman with SAH. Her cerebral angiography demonstrated a small BBA on the dorsal wall of her right ICA. Endovascular treatment that consisted of a stent-within-a-stent was attempted, but the replacement of the second stent failed, and the aneurysm became bigger. Surgery was performed by clipping the BBA with a Sundt slim-line encircling graft clip. The patient completely recovered with no complications. This treatment may be a salvageable option for BBA, especially when endovascular treatment has failed.

Glossopharyngeal neuralgia is a relatively rare condition characterized by severe, paroxysmal episodes of lancinating pain in the tongue, throat, ear, and tonsil. This disorder is assumed to be due to compression of the glossopharyngeal nerve by vascular structures. A 47-year-old woman complaining of sharp and lancinating pain in the right periauricular and submandibular areas visited our hospital. Swallowing, chewing, and lying on her right side triggered the pain. Her neurologic examination revealed no specific abnormalities. The results of routine hematologic and blood chemistry studies were all within normal limits. Carbamazepine and gabapentin were given, but her symptoms persisted. Her pain was temporarily relieved only by narcotic pain medication. MRI showed an arachnoid cyst located in the right cerebellomedullary cistern extending to the cerebellopontine cistern. Cyst removal was performed via a right retrosigmoid approach. Lateral suboccipital craniotomy was performed using the right park-bench position. After opening the dura and cerebellopontine angle, the arachnoid cyst was exposed. The arachnoid cyst was compressing the flattened lower cranial nerves at the right jugular fossa. Her symptoms resolved postoperatively. Two months after the operation, she was completely free from her previous symptoms.

PURPOSE: Several treatment options have been reported for post-traumatic kyphosis (PTK) and neurologically compromised osteoporotic fractures. However, there is no ideal surgical procedure. This study evaluated the effectiveness of posterolateral decompression and anterior support with a titanium mesh in PTK by posterior surgery. MATERIALS AND METHODS: Seventeen patients with PTK and neurologically compromised osteoporotic fractures underwent a single posterior approach. During posterior decompression, a titanium mesh was inserted through the posterior approach after a transpedicular intracorporeal corpectomy. Complications, operating time and blood loss were noted, and radiographic studies and neurological status were evaluated before surgery, after surgery, and at final follow-up. RESULTS: The mean kyphosis was 35+/-9.7degrees (range; 17-58degrees) before surgery, 3.2+/-1.8degrees after surgery (correction; 90.5%) and 5.5+/-3.2degrees at the final follow-up (correction; 85.5%). There was 29.6degrees correction of the kyphosis with a 6% loss of correction. Postoperative neurological improvement using the Frankel classification was demonstrated in all patients. There was no new onset or progressive neurological deterioration, additional surgery or extrusion of mesh. Three complications were encountered: one care each of pneumonia, prolonged ventilator support and distal adjacent vertebral fracture. CONCLUSION: The posterior insertion of a titanium mesh for anterior support appears to maintain the length of the anterior column, stabilize the injured vertebra and facilitate spinal fusion. Posterolateral decompression allows as direct a decompression as the anterior approach.
