Ruptured intracranial aneurysms in infants are rare and infantile fusiform anterior cerebral artery (ACA) aneurysms are much rarer. In this report, we described the case of a 7-month-old infant with a ruptured fusiform ACA aneurysm who presented with seizure and underwent endovascular treatment. The patient was initially in a coma and the neurologic condition did not improve after treatment. The clinical characteristics of the case and literature review were discussed.

A helical blade type of hip screw is used widely for the operative management of femoral trochanteric fractures. A 73-year-old female patient was admitted for femoral trochanteric fracture AO/OTA type 31A2.2. A helical blade locking sleeve dissembled 18 weeks after surgery did not achieve accurate reduction. The patient underwent bipolar hip hemiarthroplasty because the fracture reduction was lost, and it was impossible to remove the remaining helical blade without bone loss. The authors report this case of a rare complication of helical blade.

A genomic instability called chromothripsis occurs as a single catastrophic event, generating massive complex genomic rearrangement with a possible characteristic pattern of copy number oscillations. Here, we report a case of secondary plasma cell leukaemia (PCL) showing chromothripsis identified by single nucleotide polymorphism array (SNP-A)-based karyotyping. A 53-year-old male patient was diagnosed as having secondary PCL four years after he was diagnosed with multiple myeloma, and he died four days later due to intracerebral haemorrhage. Chromosomal analysis and fluorescence in situ hybridization (FISH) revealed the deletions of 13q and 17p and an insertion of 1q. Further, genomic aberrations that were not detected by chromosomal analysis and FISH were identified by SNP-A. In particular, SNP-A revealed numerous alternating copy number state switches involving one, two, or three copy number states on chromosome 7q, suggesting the presence of chromothripsis. The present case suggests that chromothripsis may occur in secondary PCL and can be inferred from genomic copy number profiles identified by SNP-A.

BACKGROUND: Tourniquets are used to provide a bloodless surgical field for extremities. Hypotension due to vasodilation and bleeding after tourniquet deflation is a common event. Hemodynamic stability is modulated by the autonomic nervous system (ANS). Heart rate variability (HRV) is a sensitive method for detecting individuals who may be at risk of hemodynamic instability during general anesthesia. The purpose of this study was to investigate ANS function to predict hypotension after tourniquet deflation. METHODS: Eighty-six patients who underwent total knee replacement arthroplasty (TKRA) were studied. HRV, systolic blood pressure variability (SBPV) and baroreflex sensitivity (BRS) were analyzed. We assigned two groups depending on the lowest systolic blood pressure (SBP) or mean BP (MBP) after tourniquet release (Group H; SBP < 80 mmHg or MBP < 60 mmHg, Group S; SBP > 80 mmHg and MBP > 60 mmHg). RESULTS: Fifteen patients developed severe hypotension and ten patients were treated with ephedrine. Of the parameters of HRV, SBPV, and BRS, only BRSSEQ was significant being low in Group H. BRS and high-frequency SBPV were correlated with the degree of MBP change after tourniquet deflation. CONCLUSIONS: Preoperative low BRS is associated with hypotension after tourniquet deflation, suggesting the importance of baroreflex regulation for intraoperative hemodynamic stability.

PURPOSE: The aim of this study was to provide sex-matched three-dimensional (3D) statistical shape models of the mandible, which would provide cephalometric parameters for 3D treatment planning and cephalometric measurements in orthognathic surgery. MATERIALS AND METHODS: The subjects used to create the 3D shape models of the mandible included 23 males and 23 females. The mandibles were segmented semi-automatically from 3D facial CT images. Each individual mandible shape was reconstructed as a 3D surface model, which was parameterized to establish correspondence between different individual surfaces. The principal component analysis (PCA) applied to all mandible shapes produced a mean model and characteristic models of variation. The cephalometric parameters were measured directly from the mean models to evaluate the 3D shape models. The means of the measured parameters were compared with those from other conventional studies. The male and female 3D statistical mean models were developed from 23 individual mandibles, respectively. RESULTS: The male and female characteristic shapes of variation produced by PCA showed a large variability included in the individual mandibles. The cephalometric measurements from the developed models were very close to those from some conventional studies. CONCLUSION: We described the construction of 3D mandibular shape models and presented the application of the 3D mandibular template in cephalometric measurements. Optimal reference models determined from variations produced by PCA could be used for craniofacial patients with various types of skeletal shape.

BACKGROUND: Blood transfusion is often performed to support successful brain surgery. In this study, we looked at two groups of surgery patients to analyze the transfusion requirements for patients undergoing brain surgery in our hospital. Group A patients received elective surgery, whereby blood products were prepared in advance, and Group B patients required emergency surgery which is often accompanied massive bleeding, and therefore adequate transfusion blood may not be available in advance. METHODS: During a one year period, patients who received brain surgery were classified as requiring either elective (Group A) or emergency (Group B) surgery. In each group, operation time and blood transfusion requirements were compared. RESULTS: Of the 35 total patients included in this study, 14 cases were Group A and 21 cases were group B. Average operation time was 4 hours and 13 minutes (253 minutes), and 2 hours and 50 minutes (170 minutes), respectively for Groups A and B. Red Blood Cell (RBC) transfusion was conducted in more than 90% of all patients. Average volume of RBC transfusion per operation was 2.5 units (Group A) and 3.1 units (Group B). Fresh frozen plasma (FFP) was transfused in 21% of Group A patients and in 38% of Group B patients. Platelet Concentrate (PC) was transfused in 19% of Group B patients, only. CONCLUSION: FFP and PC were more frequently transfused in patients who received emergency surgery than those who received elective surgery. Preparation of, not only RBC, but FFP and PC is required for emergency brain surgery. Therefore, efforts to retain adequate amounts of blood are needed to support emergency brain surgery.

PURPOSE: Although infants with bronchopulmonary dysplasia (BPD) are at risk of developing secondary pulmonary hypertension (PH), which is associated with significant morbidity and mortality, little has been reported about the incidence, clinical course and prognosis of PH secondary to BPD in premature infants. This study was done to investigate the incidence, risk factors, clinical course, and the ultimate prognosis of PH developed secondary to BPD in very low birth weight infants (<1,500 g). METHODS: Medical records of very low birth weight infant (VLBWI) admitted to Samsung Medical Center NICU from January 2000 to July 2007 were reviewed retrospectively. BPD was defined by Jobe's classification. The diagnosis of pulmonary hypertension was established as velocity of tricuspid valve regurgitation (TR) > or =3 m/s and a flattening of the intraventricular septum by conducting Doppler echocardiography. RESULTS: The incidence of pulmonary hypertension was 6% in VLBWI with BPD and it developed in moderate to severe BPD. The diagnosis of pulmonary hypertension was made on postnatal 133 days (range 40-224 days) and the risk factors related to developing pulmonary hypertension were severe BPD, small for gestational age and outborn infants. The mortality rate was 57% and especially higher in severe BPD (70%). The time to recovery spent 3 months (range 1-10 months) in survived patients. CONCLUSION: Based on the results of this research, pulmonary hypertension secondary to BPD in VLBWI related to severity of BPD and had a poor prognosis. We expect that regular long-term echocardiography may be helpful in treating reversible in VLBWI with moderate to severe BPD.

Periorbital edema is a rare manifestation of systemic lupus erythematosus (SLE). We describe here a patient with bilateral periorbital edema as a presenting symptom of SLE. A 23-year-old woman was admitted for a sudden onset of severe periorbital edema that developed 7 days previously. On the basis of the malar rash, arthritis of the right hand and left wrist, leukopenia, proteinuria and the positive anti-nuclear and anti-dsDNA antibodies, she was diagnosed with SLE. Kidney biopsy revealed lupus nephritis (WHO class IV). After treatment with high dose of steroids, intravenous cyclophosphamide and daily hydroxychloroquine, her symptoms resolved, including the periorbital edema. She was discharged with prescriptions for prednisolone and hydroxychloroquine and she remains well.

We report a unique case of bilateral mirror image M1 aneurysms, one of which was an unruptured aneurysm arising from the proximal end of right middle cerebral artery fenestration with long loop and the other ruptured aneurysm from the contralateral side. We clipped ruptured aneurysm first and unruptured one in three months after the first operation. The difficulties of identifying this unusual vascular anomaly and possible problems during the surgery of an aneurysm at the site of fenestration are discussed with a review of the literature.
