Spontaneous cervical epidural hematoma treated by the combination of surgical evacuation and steroid pulse therapy

A 70-year-old man on antiplatelet therapy developed sudden severe back pain in his neck with numbness and weakness in his extremities. On admission, he presented with complete quadriplegia, hypoesthesia, and anuria. Magnetic resonance imaging (MRI) revealed cervical cord compression due to an epidural hematoma posterior to the spinal cord and intramedullary hyperintensity. Surgical evacuation was performed about 12 hours after the onset, but the recovery of neurological deficits was poor. After performing 2 additional administrations of steroid pulse therapy, the patient's motor dysfunction began to improve and spinal MRI showed a recovery as well. These observations suggest that steroid administration should be considered as a post-operative additional therapy for cases with severe neurological deficits even after surgery.     

A three-year review of acute respiratory tract infections caused by Streptococcus milleri group

The objective of our study is to understand the clinical features of patients with acute respiratory tract infection associated with Streptococcus milleri group (SMG). Fifteen patients with SMG respiratory tract infection visited our hospital from July, 1997 through May, 2000. There were seven cases of pneumonia, two pulmonary abscess, three thoracic empyema and three acute bronchitis. The mean age of the patients was 57.8 years (range 16-87), twelve were males, and seven were smokers. The moderately to severe underlying diseases existed in thirteen patients (86.7%) and included the following: respiratory diseases (20.0%), history of the esophageal or gastric surgery (26.7%), central nerve system diseases (13.3%), alcohol intake (60.0%), hepatitis and pancreatitis (33.3%), diabetes mellitus (13.3%) and malignancy (6.7%). The species of SMG detected were as follows: S. constellatus, 8, S. anginosus, 6 and S. intermedius, 1. Anaerobic organism and other microorganisms were detected in five patients. A patient with SMG nosocominal pneumonia who previously had thoracic surgery for esophageal cancer died. Antibiotics therapy with carbapenem or combination therapy, drainage and no surgery, were successful in 14 of the 15 cases (93.3%). The number of intermediately or complete resistant strains against penicillin G, ampicillin and cefmetazole were 5 (33.3%), 8 (53.3%) and 12 (80.0%), respectively in this series. Recently, it is seemed that acute respiratory tract infections caused by SMG are increasing in the patients with moderately to severe underlying diseases, and several clinical strains of SMG are acquiring a tolerance to antibiotics.     

Decreased CTLA4+ and Foxp3+ CD25highCD4+ Cells in Induced Sputum from Patients with Mild Atopic Asthma

BackgroundDetails of the comparisons between airway and peripheral blood regulatory T cells (Tregs) in patients with atopic asthma are still unclear. The objective of this study is to investigate the profiles of both airway and circulating Tregs in atopic asthma.MethodsWe measured the numbers of Tregs and eosinophils in induced sputum and peripheral blood in 28 patients with mild atopic asthma and compared these with numbers in 18 healthy controls. The frequency (%) of Tregs (surface CTLA4⁺, intracellular Foxp3⁺, and CTLA4⁺Foxp3⁺ on CD25^highCD4⁺ T cells) in sputum and blood was determined by intracellular 5-color flow cytometry. We also correlated the numbers with the level of airway hyperresponsiveness (AHR) in asthmatics.ResultsThe mean frequencies of cells expressing CTLA4⁺ (19.4 ± 2.1%, p = 0.075), Foxp3⁺ (16.4 ± 3.3%, p = 0.001), and CTLA4⁺Foxp3⁺ (7.0 ± 1.1%, p = 0.008) in induced sputum from asthmatics were significantly lower than controls (27.2 ± 3.7%, 37.4 ± 4.7%, and 18.2 ± 3.6%, respectively), whereas in peripheral blood, there was no inter-group difference in the frequencies of cells expressing CTLA4⁺ (7.1 ± 1.5% vs 5.7 ± 1.7%, p > 0.05), Foxp3⁺ (35.7 ± 3.2% vs 21.1 ± 3.9%, p > 0.05), and CTLA4⁺Foxp3⁺ (6.6 ± 1.5% vs 4.2 ± 1.0%, p > 0.05). Moreover, the frequency of CD25^highCD4⁺ cells expressing CTLA4⁺, but not Foxp3⁺, in induced sputum was associated with AHR (r = 0.60, p = 0.009) and airway eosinophilic inflammation (r = ? 0.60, p = 0.008) in asthmatics.ConclusionsAirway, but not circulating, Tregs are decreased in mild atopic asthmatics, and are negatively correlated to an increase of airway eosinophilic inflammation and AHR.     

Two cases with hepatic amyloidosis suspected of having primary sclerosing cholangitis

Sclerogenic biliary changes in hepatic amyloidosis are seldom observed. Here, we report two recent cases initially suspected as primary sclerosing cholangitis (PSC), which were later diagnosed as hepatic amyloidosis (AL type). Case 1: On the basis of magnetic resonance cholangiopancreatography (MRCP) findings, PSC was suspected in a 41‐year‐old woman with jaundice. Computed tomography (CT) showed nodular pulmonary lesions and swollen cervical, mediastinal and para‐aortic lymph nodes, the cause of which was unknown despite detailed examinations. Because of rapid deterioration in the patient's liver function, living donor liver transplantation was performed. She was then diagnosed with hepatic amyloidosis, but died of heart failure due to cardiac amyloidosis 74 days after surgery. Case 2: On the basis of MRCP findings, PSC was suspected in a 49‐year‐old woman with jaundice. CT showed multiple cystic pulmonary lesions, and hypogammaglobulinemia was also observed (immunoglobulin G, 481 mg/dL). After a biliary plastic stent was placed, liver and lung biopsy confirmed the presence of amyloid deposition. These two cases indicate that it is important to consider hepatic amyloidosis as a differential diagnosis of PSC. The presence of atypical extrahepatic lesions may be useful clues for confirming the diagnosis.     

Pseudoaneurysm of the Cystic Artery Secondary to Cholecystitis as a Cause of Hemobilia: Report of a Case

Spontaneous intracholecystic bleeding is very rare. We report herein a very rare case of a pseudoaneurysm of the cystic artery due to acute cholecystitis. A 58-year-old man presented at the emergency department complaining of colicky pain in the right upper quadrant. Dynamic magnetic resonance imaging demonstrated an early-enhanced pooling of contrast material (suggestive of a pseudoaneurysm of the cystic artery) inside the neck of the gallbladder. After the proximal control of the hepatic artery, the patient underwent a cholecystectomy and a ligation of the cystic artery. The resected specimen of the gallbladder showed evidence of a massive intracholecystic hematoma. Proximal to the impacted gallstone in the neck, a 2-cm diameter saccular-type pseudoaneurysm was identified. Although a pseudoaneurysm of the cystic artery is very rare, it should be included in the differential diagnosis of hemobilia. Once the pseudoaneurysm is confirmed, its embolization before a cholecystectomy (which can be attempted laparoscopically) may be useful to ensure the safety of the patient.     

Recurrent pancreatitis caused by ampullary carcinoma and minor papilla adenoma in familial polyposis: Report of a case

We report a case of relapsing pancreatitis in familial adenomatous polyposis (FAP) with severe duodenal adenomatosis (Spigelman’s stage IV). A 58-year-old man who had undergone total colectomy for FAP 18 years earlier was hospitalized for carcinoma arising from the residual rectum. He had experienced several episodes of upper abdominal pain and ultrasonography and computed tomography (CT) showed diffuse calcification of the atrophic pancreas, suggestive of chronic pancreatitis. He had severe diabetes mellitus, but had no symptoms of pancreatic exocrine dysfunction. Upper endoscopy showed multiple duodenal adenomas including carcinoma involving the papilla of Vater. To remove these duodenal adenomas and ampullary carcinoma and prevent recurrent pancreatitis, we performed pancreaticoduodenectomy. On pathologic examination, the major duodenal papilla was completely obstructed by the carcinoma, and the minor papilla was also involved by the adenoma. The patient has no evidence of disease and has experienced no pancreatitis in 3 years of follow-up.
