Statistical observations of pemphigus at the Nara University Hospital from 1975 to 1989

From 1975 to 1989, 12 patients with pemphigus vulgaris (PV) and 19 with pemphigus foliaceus (PF) were treated with systemic or topical corticosteroids at the Nara University Hospital. All 12 patients with PV were treated with oral corticosteroids (initial dose of prednisolone: 15-70 mg/day) and 4 of 12 patients showed prolonged clinical remission (up to 9 years) without corticosteroids. Of 19 patients with PF, 16 patients were treated with oral corticosteroids (initial dose of prednisolone: 8-40 mg/day) and 3 patients were treated with only topical application of corticosteroids. In PF, 7 of 16 patients treated with systemic corticosteroids and all 3 patients treated with topical corticosteroids also showed prolonged clinical remission (up to 10 years). These observations suggest that most of the patients with pemphigus respond well to the treatment of relatively small or moderate dosage of corticosteroids.     

Carpal instability in rheumatoid wrists

This study was conducted to identify patterns of carpal instability in the rheumatoid wrist. One hundred patients with proven rheumatoid arthritis were randomly chosen, and posteroanterior and lateral radiographs of right wrists were taken. The most common isolated pattern was volar intercalated segmental instability, apparent in 16 wrists, while nine wrists had scapholunate dissociations. Larsen grading scores revealed a correlation between disease duration, carpal height ratio, and ulnar translocation index. In the early stages of disease, the scapholunate angle was significantly increased and the lunate rotated volarly due to loosening of the intrinsic carpal ligament. In later phases, the capitolunate angle significantly increased and the capitate rotated dorsally. Patterns of carpal instability in rheumatoid wrists seem to be complicated, involving combined laxity of the intrinsic and extrinsic carpal ligaments.No benefits have been received from a commercial party directly or indirectly related to the subject of this article.An erratum to this article can be found at     

Mediastinal neurilemmoma originating in the right phrenic nerve: a case report]

We report on a 31-year-old man with a mediastinal neurilemmoma originating in the right phrenic nerve. The patient was admitted because of abnormal chest X-ray shadows observed during a routine checkup. A preoperative diagnosis of bronchial cyst in the mediastinum was made. The tumor was resected by video-assisted thoracic surgery. It was 3 x 4 x 3 cm in size, weighted 15 g, and originated in the right phrenic nerve. The histopathologic diagnosis was mediastinal neurilemmoma. Only 14 cases have been reported in the Japanese literature.     

A case of pulmonary squamous cell carcinoma coexisting with pulmonary actinomycosis]

A 71-year-old man was referred to our hospital complaining of cough. Chest radiography revealed a mass opacity in the right upper lung field. A transbronchial biopsy specimen revealed non-specific inflammatory changes. Percutaneous lung aspiration biopsy under ultrasound guidance demonstrated gram-positive rods, suggesting actinomyces. On the diagnosis of pulmonary actinomycosis, the patient was treated with penicillin-G and his symptoms were relieved. In a three-month follow-up, the mass shadow in the right upper lung field was found to have increased in size. Squamous cell lung cancer was diagnosed on the basis of repeated transbronchial tumor biopsies, and right upper lobectomy was performed. Most cases of pulmonary actinomycosis have been diagnosed from post-surgical tumor specimens taken on suspicion of the presence of lung cancer. However, the lung cancer in this case was difficult to diagnose because the lung cancer was co-existent with pulmonary actinomycosis.     

Urinary reconstruction in vertebral,anorectal, cardiac,trachea‐esophageal,renal abnormalities and limb defects association with chronic renal failure and penile duplication

Various urological complications in VATER association require careful management. A 15‐year‐old boy with VATER association, including a hypoplastic lower urinary tract and diphallia, presented with chronic kidney disease and incontinence after a right loop ureterostomy. In order to acquire urinary continence without renal function impairment, an ileocecal reservoir with umbilical catheterizable stoma was created as a urinary reconstruction. The ectopic posterior penis was resected for cosmetic reasons, and the stump of the hypoplastic urethra was opened at the perineal skin. Clean intermittent self‐catheterization through the umbilicus using disabled bilateral limbs was then achieved. This report describes the management of VATER association in a patient with complicated urological anomalies.     

Comparison of myocardial perfusion by distal protection before and after primary stenting for acute myocardial infarction: angiographic and clinical results of a randomized controlled trial.

OBJECTIVES: To assess the myocardium-reperfusing effect of a distal protection device, GuardWire Plus (GuardWire Plus), in patients with acute myocardial infarction (AMI). BACKGROUND: Distal embolization may result in reduced myocardial perfusion, increasing the risk of non-Q-wave myocardial infarction and death. Distal protection devices may protect the microcirculation from embolic debris, improving short- and long-term clinical outcomes. METHODS: From February 2002 to July 2003, a total of 341 AMI patients at 22 institutions in Japan were enrolled in the present, multicenter, prospective, randomized trial. Patients experiencing AMI within 12 hr of symptom onset, who were considered treatable by stenting and who met the inclusion criteria, were eligible for randomization. Stenting with and without GuardWire Plus was conducted to examine whether the device provides faster and more complete ST-segment resolution, smaller infarct size, and improved myocardial blush score. RESULTS: The rates of slow flow and no-reflow immediately after PCI were 5.3 and 11.4% in the GuardWire Plus and control groups, respectively (P = 0.05). Blush score 3 acquisition rates immediately after PCI were 25.2 and 20.3% in the GuardWire Plus and control groups, respectively (P = 0.26), and the rates at 30 days after PCI were 42.9 and 30.4%, respectively (P = 0.035). CONCLUSIONS: A significant difference was found between the GuardWire Plus and control groups with respect to the total incidence of distal embolization, indicating that GuardWire Plus angiographically improved myocardial perfusion without demonstrating the preventive effect of myocardial damage.     

Early effects of lafutidine or rabeprazole on intragastric acidity: which drug is more suitable for on-demand use?

Background Medication for the relief of heartburn should have the rapid onset of action required for on-demand use. We studied the inhibition of gastric acid secretion by lafutidine and rabeprazole, given in single doses to fasting and postprandial subjects.Methods A total of 22 healthy male, Helicobacter pylori-negative volunteers participated in this randomized, two-way crossover study. They were randomly assigned to receive a single oral dose of 10mg lafutidine or 20mg rabeprazole after fasting overnight (12 subjects, fasting study) or after eating a test meal (noodles, 364kcal; protein, 10.1g; fat, 16g; carbohydrates, 44.9g; NaCl, 1.1g; 10 subjects, postprandial study). Intragastric pH was monitored continuously for 6h after treatment. The other drug was given after a washout period of at least 7 days, and intragastric pH was similarly monitored.Results In the fasting study, lafutidine sustained pH at >3 and >4 during the second, third, fourth, fifth, and sixth hours of the study for significantly longer than rabeprazole. During the first 6h after treatment, lafutidine sustained pH at more than 2, 3, 3.5, 4, 5, 6, and 7 longer than rabeprazole. In the postprandial study, lafutidine sustained pH >3 and >4 for longer periods than rabeprazole during the third, fourth, fifth, and sixth hours of the study. During the first 6h after treatment, lafutidine sustained pH at more than 2, 3, 3.5, 4, 5, 6, and 7 longer than rabeprazole.Conclusions Lafutidine 10mg produces a prompter rise in intragastric pH than rabeprazole 20mg in fasting and postprandial Helicobacter pylori-negative male subjects.
