We studied to assess the relationship between intrauterine growth retardation and theincreased nucleated red blood cell counts (NRBC) in small for gestational age (SGA) and appropriatefor gestational age (AGA) neonates with low birth weight. We also evaluated the nucleated red blood cell counts in low birth weight neonates who had either perinatal asphyzia or hyaline membrane disease (HMD) or died within 7 days after birth. The results were as follows: 1) In low birth weight neonates, the mean value for NRBC counts was 9.02/100 WBCs and the mean absolute value for NRBC counts was 0.9210E9/L. 2) The mean values for NRBC counts were 13.4/100 WBCs in SGA and 6.4/100WBCs in AGA. The mean absolute values for NRBC were 1.32x10E9/L in AGA neonates 3) In SGA neonates with low birth weight, the mean NRBC counts wers 19.6/100WBCs in asphyxiated group and 4.5/100WBCs in control group. The mean absolute NRBC counts were 1.9810E9/L in control group. 4) In AGA neonates with low birth weight, the mean NRBC countswere 9.1/100WBCs in asphyxiated group and 2.4/100WBCs in control group. The meanabsolute NRBC counts were 0.98x10E9/L in asphyxiated group and o.23x10E9/L in controlroup. 5) The mean NRBC counts were 13.8/100WBCs in neonates with HMD and 7.1/100WBCs in control group. The mean absolute NRBC counts were 1.50x10E9/L in neonates withHMD and 0.70x10E9/L in control group. 6) The mean NRBC counts were 19.9/100 WBCs in expired group and 6.8/100WBCs in suvived group. The mean absolute NRBC counts were 2.1810E9/L in expired group and 0.66x10E9/L in survived group. 7) The NRBC counts of SGA neonates were significantly higher than that of AGA neonates with low birth weight. 8) The NRBC counts of asphyxiated neonates were significantly higher than that of the control group. 9) The NABC counts of expired neonates were significantly higher than that of the control group. 10) The NRBC counts of expired neonates were significantly higher than that of the survived neonates.

An inflammatory myofibroblastic tumor (IMT) is a rare tumor that is currently classified as an intermediate cancer according to the World Health Organization classification system. The pathophysiology of its occurrence is still unknown. Imaging tests, such as CT or MRI, can be helpful in diagnosis, but the final diagnosis is confirmed by a pathological examination through a biopsy and immunohistochemistry stain. The patient, in this case, presented an asymptomatic intrahepatic mass discovered incidentally on an imaging examination. Initially, intrahepatic cholangiocarcinoma was suspected, but she was finally diagnosed with IMT through a histological examination after a liver resection.

Tuberculoma of the lungs is not an uncommon finding, but an ectopic liver in the lung is extremely rare. Pulmonary tuberculosis presenting as tuberculoma can be diagnosed radiologically, but its definite diagnosis is established by confirmation of the acid-fast bacillus or the unique histology. We report here on a case of tuberculoma of the left lower lobe that was erroneously diagnosed as ectopic liver by ultrasono-guided fine needle aspiration biopsy. An understanding of the normal variants of the liver can prevent a patient from undergoing an unnecessary invasive procedure.

OBJECTIVE: Anterior cervical discectomy and fusion (ACDF) is a choice of surgical procedure for cervical degenerative diseases associated with radiculopathy or myelopathy. However, the patients undergoing ACDF still have problems. The purpose of the present study is to evaluate the radiologic results of 3 different methods in single-level ACDF. METHODS: We conducted a retrospective collection of radiological data from January 2011 to December 2014. A total of 67 patients were included in this study. The patients were divided into 3 groups by operation procedure: using stand-alone cage (group cage, n=20); polyether-ether-ketone (PEEK)-titanium combined anchored cage (group AC, n=21); and anterior cervical cage-plate (group CP, n=26). Global cervical lordosis (C2-C7 Cobb angle), fused segment height, fusion rate, and cervical range of motion (ROM) were measured and analyzed at serial preoperative, postoperative, 6-month, and final 1-year follow-up. RESULTS: Successful bone fusion was achieved in all patients at the final follow-up examination; however, the loss of disc height over 3 mm at the surgical level was observed in 6 patients in group cage. Groups AC and CP yielded significantly better outcomes than group cage in fused segment height and cervical ROM(p=0.01 and p=0.02, respectively). Furthermore, group AC had similar radiologic outcomes to those of group CP. CONCLUSION: The PEEK-titanium combined anchored cage may be a good alternative procedure in terms of reducing complications induced by plate after ACDF.

A case of a patient diagnosed as the chronic spinal epidural hematoma in the lumbar region is reported. There was no history of trauma except the repeated epidural block for controlling the lower back pain at the pain clinic. The symptoms were occurred after epidural block and were exaggerated by repeated injections. Magnetic resonance imaging showed a spinal epidural mass located dorsolaterally at the level of L3-L4. After removal of the hematoma, the symptoms were completely relieved. The diagnosis of a chronic spinal epidural hematoma was confirmed with both operative and histological findings.

There are few reported cases of post-operative spondylitis caused by Mycobacterium intracellulare. A 75-year-old female presented to our hospital with low back pain and paraparesis after a fall. The radiologic examination revealed compression fractures of L1, L3 and L4 and an epidural hematoma compressing the spinal cord. The dark-red epidural hematoma was urgently evacuated. Four weeks post-operatively, neurologic deficits recurred with fever. On magnetic resonance image, an epidural abscess and osteomyelitis were detected in the previous operative site. Five weeks post-operatively, revision was performed with multiple biopsies. The specimen were positive for acid-fast bacilli and traditional anti-tuberculous medications were started. Because the Polymerase Chain Reaction for non-tuberculous mycobacterium (NTM) was positive, the anti-tuberculous medications were changed to anti-NTM drugs. However, the neurologic deficits did not improve and persistent elevation of erythrocyte sedimentation rate and C-reactive protein were noted. Eight weeks after the revision, Mycobacterium intracellulare was detected in the specimen cultures. Despite supportive care with medication, the patient died due to multiple organ failure.

OBJECTIVE: This study evaluated the efficiency of a curved polyetheretherketone (PEEK) cage in comparison with a wedge PEEK cage according to radiologic and clinical outcomes in patients with cervical degenerative disease. METHODS: A total of 37 patients who suffering from cervical disc disease with radiculopathy or myelopathy were reviewed retrospectively. Seventeen patients were underwent anterior cervical discectomy and interbody fusion with a curved shape PEEK cage (curved cage group), and twenty patients with wedge shape PEEK cage (wedge cage group). Clinical assessment was graded using Odom's criteria, NDI score and VAS score. For radiologic analysis, disc height (DH), segmental angle (SA), subsidence were measured at the preoperative and last follow up. RESULTS: A comparison of the preoperative and postoperative results revealed improvements after the surgery in the DH and SA in both cage groups. The change of postoperative DH between the preoperative and the last follow-up in wedge cage group and curved cage group was 6.85% and 25.5%, respectively. The change of postoperative SA was 1.75degrees and 0.95degrees, respectively. There was no statistically significant difference in the DH and SA between the 2 groups. The subsidence rate in the wedge cage group and curved cage group was 20% and 6%, respectively. CONCLUSION: The 2 different cage groups showed significant improvements in the disc height, segmental angle and clinical outcomes. However, the shape of PEEK Cage influences the tendency for subsidence. Increasing contact surface area and fitting into two adjacent vertebral body prevent significant subsidence.

OBJECTIVE: This study evaluated the prognostic factors that influence the surgical outcomes of elderly patients older than 65 years old with an aneurysmal subarachnoid hemorrhage. METHODS: Ninety-two patients older than 65 years old, who were operated in our hospital between 1998 and 2005, were reviewed retrospectively. The clinical outcomes were evaluated using the modified Rankin Scale three months after surgery. RESULTS: The preoperative neurological status, such as the Hunt-Hess grade (p<0.001), World Federation of Neurological Surgeons (WFNS) grade (p<0.001), and the Fisher grade (p=0.001), was significantly associated with the surgical outcomes in this series. The vasospasm (0.016) and ventriculostomy (0.039) are factors influencing the surgical outcomes. However, the other factors including hypertension (0.831), smoking (0.228), accompanying disorder (0.706), size of aneurysms (0.177), location of aneurysms (0.755), shunt operation (0.356), and timing of surgery (0.194) had no influence on the surgical outcome. CONCLUSION: In elderly patients with intracranial aneurysms, the preoperative neurological status, vasospasm, and ventriculostomy are the most significant prognostic factors.

Cervicomedullary junction arteriovenous malformation(AVM) is extremely rare. The authors present a case of a cervicomedullary junction AVM in a 31-year-old woman presenting with recurrent intraventricular hemorrhage(IVH). Magnetic resonance imaging revealed the AVM(of a size of approximately 2X2.5X4cm) extending from a lower medulla to C2-3 level. Vertebral angiography demonstrated a tightly coiled vascular mass with multiple feeders (radiculomedullary arteries) and irregular-shaped aneurysm at distal part of feeder originating at right C-1 level. The patient underwent superselective embolization of upper nidus and the aneurysm. The pertinent literature is reviewed, and diagnostic and therapeutic implications are discussed.

Cholesterol granuloma of frontal bone is a rare disease which usually occurs at the lateral part of the supraorbital ridge. This expanding lesion grows slowly and extends into the orbit and anterior cranial fossa. The most common symptom is proptosis. This granuloma is composed of a granulomatous reaction surrounding cholesterol crystals. Surgical treatment involves aspiration of contents and stripping or curettage of the lining which is highly successful. We experienced a case of cholesterol granuloma of frontal bone with huge intracranial extension, which was cured by surgical removal. The clinical features, radiologic, and pathologic finding were discussed and the pertinent literatures were reviewed.
