A 60-year-old man who developed a nephrotic syndrome underwent a renal biopsy, and the case was diagnosed as membranoproliferative glomerulonephritis (MPGN). Despite chemotherapy using steroid, immunosuppresive and anticoagulant drugs, the patient exhibited persistently high urinary protein levels (above 8 g/day), and the renal function deteriorated gradually.
One and half years later, hemodialysis was started, but soon he had a high fever (above 38-40°C). Laboratory data revealed high levels of both antinuclear antibody titer and immune complex (IC) titer, and a low level of CH50.
Considering an active collagen disease like SLE, steroid pulse therapy and plasma exchange were instituted. The therapy was very effective this time.
It is well known that many patients with SLE and a long term history of hemodialysis develop a condition of so called “burn out” in which the activity of SLE declined to allow the withdrawal of steroid therapy. Also well known is the developement of hypocomplementemia in many patients with MPGN.
In our case, it was difficult to clarify what caused the high fever and other clinical symptoms. We must carefully observe the clinical symptoms of SLE.

We report two cases of farm chemical poisoning which were treated successfully. Two elderly men separately swallowed down paraquat/diquat solutions in an attempt to kill themselves, and resultantly developed pulmonary fibrosis. After steroid therapy, clinical symptoms desappeared, although a slight degree of abnormality remained on chest X-rays. Case 1: a 57-year-old man; the amount of ingestion, 100 ml; hospitalized 2 hours after ingestion; shock, (-); urinary PQ reactoin, (2); serum PQ level, 1.14 ug/ml; pulmonary injury at first examinatoin, (-); pulmonary manifestation of symptoms, at day 3 after hospitalization; minimum Pao₂, 67.6 mmHg. Case 2: a 65-year-old man; the amount of ingestion, one gulp; hospitalized 27 minutes after ingestion ; shock, (-); urinary PQ reactoin, (3+); serum PQ level, 6.6ug/mg; pulmonary injury at first examination, (-); pulmonary manifestation of symptoms, at day 5 after hospitalization; minimum Pao₂, 58.3mmHg. For treatment, gastrointestinal lavage, forced diuresis and direct hemoperfusion were performed in both cases. Steroid pulse therapy was followed by repeated oral administration of large doses of steroid.
Hepatic and renal disorders were transient. Pao₂ was normal when the patients were discharged. The primary reasons we could save their lives are probably that the amount of PQ ingestion was relatively small, hemodialysis was performed repeatedly at early stages, and that large amounts of steroid were used immediately after the onset of pulmonary fibrosis.

We studied 494 patients with lung cancer who had been treated in our hospital from January 1985 through December 1994. Of the total number of cases, 20.4% were stage I; 4.5%, stage II; 12.1%, stage IIIA; 23.8%, stage IIIB; and 34.3%, stage IV. The 5-year-survival rate of patients with non-small cell lung cancer (NSCLC) was 61.0% in stage I, 43.4% in stage II, 21.2% in stage IIIA, 0% in stage IIIB and 0.9% in stage IV. The 3-year-survival rate and median survival time (MST) of patients with small cell lung cancer was 10.3% and 13.7 months in limited disease, and 0% and 4.8 months in extensive disease.
By histologic type, the 5-year-survival rate of patients with NSCLC was 19.7% in squamous cell carcinoma, 19.5% in adenocarcinoma and 5.3% in large cell carcinoma. The 5-year-survival rate of patients who were discovered by health screening was 39.4%; by subjective symptoms, 9.8%; and during the observation of other diseases, 14.7%. The 5-year-survival rate and MST of the patients with NSCLC treated in the Department of Internal Medicine of our hospital (stage III or IV) from 1985 through 1989, and from 1990 through 1994, were 1.9% and 7.4 months in the former period, and 3.7% and 9.9 months in the latter. Approximately 75% of the cases of lung cancer treated in our hospital were stage III or IV disease, and prognosis was very poor. Therefore, prevention and detection in the early stage of lung cancer are important.

A 48-year-old man was readmitted to the hospital because of severe intraventricular conduction defects (QRS duration was 0.30 sec). The patient had been given pilsicainide hydrochloride (150 mg/day) prior to the hospitalization. The blood tests revealed that the concentration of pilsicainide was 3.30 μg/ml, which was several times higher than the average value in patients given in a dosage of 150 mg per day. Five months before the second admission, impaired left ventricular (LV) myocardial function and paroxymal atrial fibrillation were observed in the patient. His illness was diagnosed as myotonic dystrophy as the patient presented with skeletal muscle atrophy, premature frontal baldness, hatchet face, cataract, and testicular atrophy. The trial of remedication with pilsicainide in the same dosage for seven days did not produce the toxic effects as seen previously. Both load-dependent LV dysfunction in myotonic muscular dystrophy and moderately impaired renal function in the patient probably underlay the state of intoxication.

We examined the clinical features, 12-leads ECG, Holter ECG, monitor ECG, and electrophysiologic study (EPS) in nine consecutive paroxysmal atrioventricular block (PAVB) patients treated in our hospital between 1995 and 2000. In some of them, parasympathetic nerve stimulating maneuvers, drug administration and head-up tilt test (HUT) were performed as provocative tests. EPS documented that the sites of AV block were within the His-Purkinje system (H-PSB) in five patients, proximal to the His bundle potential (AHB) in three patients. In the remaining one patient, the His bundle potential was not recorded. The main features of the patients with H-PSB were as follows: 1) often wide QRS complex with or without axis deviation; 2) variable degrees of AV conduction disturbance in a short period; 3) sinus tachycardia, and normal length and constant PQ intervals in a daytime being apt to precede PAVB; 4) rather long ventricular asystoles leading to abrupt syncope; 5) easy induction of the block by intravenousadministration of atropine. In the other hand, the features of the patients with AHB included: 1) narrow QRS; 2) progressively increasing or decreasing in PQ intervals preceding PAVB; 3) ventricular asystole lasting about 3 to 10 seconds; 4) the failure to induce PAVB by any probale provocative tests.
Although we treated all the patients with permanent pacemakers, there might have been other management method for AHB patients who had about 3-second ventricular asystole.

The objective of this study was to assess the possibility of developing a clinical minimally invasive and standardized method to evaluate the relationship between the microstructure of the jaw bone and systemic bone turnover. For this purpose, we performed standardized bone biopsy of the alveolar bone, and compared the 3D bone microstructure using micro-computed tomography (micro-CT) with bone mineral density (BMD) of the lumbar spine and biochemical markers of bone turnover. We evaluated a total of 9 samples taken from 6 patients by standardized biopsy using a trephine bur. BMD was evaluated using dual energy X-ray absorptiometry (DXA). Regarding the biochemical markers of bone turnover, serum bone-specific alkaline phosphatase (BAP) and serum osteocalcin (OC) were used as bone formation markers, and urinary cross-linked N-telopeptides of type I collagen (NTx) and urinary deoxypyridinoline (DPD) were selected as bone resorption markers. We scanned micro-CT images of these samples. Bone volume fraction (BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N), trabecular spacing (Tb.Spac), fractal dimension, trabecular bone pattern factor (TBPf) and node-strut (Nd.Nd/TV, TSL/TV) were measured. Regarding the correlations between the parameters of bone microstructures, TB/TV, Tb.N, fractal dimension, and node-strut seemed to be positively correlated and Tb.Spac and TBPf seemed to be negatively correlated with each other, but Tb.Th seemed to have a low correlation with other parameters. OC and/or BAP showed a significantly high correlation with many structural parameters (p<0.05%). In conclusion, some microstructural parameters may change according to the systemic bone turnover.

Objective: Many patients in Kagawa University Hospital are administered medicines prepared by the simple suspension method.  Pharmacists in charge of these patients receive inquiries from doctors and nurses regarding the suitability of medicines for the simple suspension method.  Answering these inquiries is complicated and time-consuming as multiple data sources need to be searched.  In order to simplify these complicated procedures, we herein attempted to develop a novel database to provide valuable information that could contribute to the safe performance of the simple suspension method, and evaluated its usefulness.
Method: The specifications of the database were determined by analyzing previously answered inquiries.  To evaluate the usefulness of the database, we used test prescriptions and compared the amount of time required to gather information using the database and the conventional method, i.e., using books alone.  We also analyzed previous prescriptions with the database in order to determine what kinds of problems could be detected.
Results: The investigation of previous prescriptions indicated that some medicines needed to be examined not only for their suitability for the simple suspension method, but also their incompatibility.  Therefore, we added a feature regarding the incompatibility of medicines to the database.  The time required to gather the information needed to answer the test prescription was shorter with our database than with the conventional method.  Furthermore, the database improved the detection of medicines that require particular attention for their properties including incompatibility.  An analysis of previous prescriptions using our database indicated the possibility of incompatibility in half of the previous prescriptions examined.
Conclusion: Our database could rapidly provide information related to the simple suspension method, including the incompatibility of medicines.

A 73-year-old man was admitted to the hospital on March 31, 2000 because of nonsustained ventricular tachycardia (VT). In 1983, he was diagnosed as having apical hypertrophic cardiomyopathy (APH). Electrocardiograms showed high amplitude of R waves and giant negative T waves (GNT), and left ventriculography (LVG) revealed spade like configuration. He stopped medication without leave six months after the diagnosis. The latest ECG showed a decrease in amplitude of R waves, no signs of GNT, ST elevation in precordial leads, and an increase in QRS duration. LVG demonstrated midventricular obstruction, apical aneurysm, and the intraventricular pressure gradient in systolic phase was 56 mm Hg. No stenotic lesion was observed in coronary arteriography. Early diastolic paradoxic flow from the apical chamber toward the outflow of the left ventricle was detected by pulsed Doppler echocardiography. VT was successfully treated with beta-blocker and amiodarone, but he needed hospital treatment again one month later because of congestive heart failure. During the follow-up of APH, the decrease in amplitude of R waves and disappeasance of GNT, ST elevation, and the increase in QRS duration in electrocardiograms, and the detection of early diastolic paradoxic flow by echocardiography could be the predictors of developing apical aneurysm and/or left ventricular dysfunction.

As regards to low back pain of agricultural worker, there are many problems still as to a syndrom of “Nofusho” in rural medicine, a disease in ocupational medicine and clinic of orthopedic.
Agricultural worker who complained of low back pain varies with their country and farm products, and it tend to increase with adding to their age. Further, the female rate of low back pain showed slightly high tendency than the made rate, 8.5-12.5 % of male, 6.5-13.4 % of female always complained of low back pain.
According to the findings of roentogenographic examination of back bone, the deformed vertebrae was found clearly, especially, low back pain caused by a trauma of soft tissue and iscogenic pain showed in farmers. Therefor, it is necessary to be improved working posture and condition.
In comparrison with non-farmer, it is located in order of truck drivers. bus drivers and repairmen.

Methods: We included 62 patients who underwent combined LLIF surgery and PPS fixation for degenerative lumbar spondylolisthesis with spinal canal stenosis. We compared the patient demographics and the accuracy of fluoroscopy-guided PPS placement between two groups: patients who remained in the lateral decubitus position for the pedicle screw fixation (single-position surgery [SPS] group) and those who were turned to the prone position (dual-position surgery [DPS] group). Results: There were 40 patients in the DPS group and 22 in the SPS group. Of the 292 PPSs, only 12 were misplaced. In other words, 280/292 screws (95.9%) were placed correctly in the pedicle’s cortical shell (grade 0). PPS insertion did not cause neurological, vascular, or visceral injuries in either group. The breach rates for the DPS and SPS groups were 4.1% (grade 1, 5 screws; grade 2, 3 screws; grade 3, 0 screw) and 4.1% (grade 1, 2 screws; grade 2, 2 screws; grade 3, 0 screw), respectively. Although there were no statistically significant differences, the downside PPS had more screw malpositioning than the upside PPS. Conclusions We found that PPS insertion with the patient in the decubitus position under fluoroscopic guidance might be as safe and reliable a technique as PPS insertion in the prone position, with a misplacement rate similar to that previously published.
