1. A therapeutic trial of intravenous hematin is presented. Eleven cases of AIP and one of VP who did not improve with conventional treatment (high carbohydrate intake) received this new agent. 2. Urinary ALA, PBG and, when possible, uroporphyrin and coproporphyrin were used to monitor the chemical response to the treatment. Objective clinical parameters of hypertension and tachycardia were followed when present in addition to subjective estimates of acute porphyric symptomatology (abdominal pain, backache, extremity pain and paresthesias, weakness, depression, etc.). 3. At a dosage of approximately 3 mg/kg, diminution of urinary ALA and PBG excretion was achieved in every patients. Hypertension and tachycardia improved in those instances where they were observed in association with the attack. Also, subjective improvements in the clinical status of the patients were observed frequently. 4. Hematin appears to be a promising therapeutic agent for the treatment of acute attack forms of porphyria.

We reviewed 166 cases of renal cell carcinoma. The presenting symptoms varied from vague backache to hypovolemic shock. The most common symptoms were pain, hematuria, a palpable mass and hypertension. Most cases involved were clear cell carcinoma (83 per cent) and survival was no better than in cases of granular cell carcinoma. The tumors metastasized to almost every organ of the body. Bilateral simultaneous primary renal cell carcinoma is described in 1 patient, who has survived for more than 5 years. The over-all 5-year survival rates of simple and radical nephrectomy were 32 and 66.6 per cent, respectively. Radiation therapy does not improve survival irrespective of stage. The 5-year survival rate with renal vein involvement was 32 per cent. Nephrectomy in patients with distant metastasis did not alter survival. Among the patients with metastasis 74 per cent were dead before 1 year and 96 per cent before 3 years.

Prior experience with the rare combination of horseshoe kidney and significant atherosclerotic vascular disease suggests difficulty in intraoperative management, often requiring division of the renal isthmus or sacrifice of some renal tissue. Seven patients have been managed successfully over the past ten years at The Ohio State University Hospital. There were six men and one woman, ranging in age from 39 to 66 years. Of the five patients with abdominal aortic aneurysm, four had a pulsatile abdominal mass, three had abdominal pain, and one had back pain. The other two patients had progressively symptomatic aortoiliac disease. All seven patients had hypertension, easily controlled by medication. Critical diagnostic procedures are preoperative intravenous pyelogram (IVP) and abdominal aortic arteriogram. The IVP detected the previously unsuspected diagnosis in 100% of the cases. The arteriogram accurately located the aneurysm in relation to the renal vascular supply, and disclosed aberrant blood supply in three of four patients with aberrant vessels. All seven horseshoe kidneys were fused at the lower pole. The operative approach involves meticulous dissection of the aberrant blood supply to the kidneys, and mobilization of the isthmus for adequate retrorenal aortic exposure. In six of the seven patients, the grafts were placed posterior to the isthmus. There were no deaths, and there were no complications related to the presence of the horseshoe kidney. In three of the seven patients, hypertension improved. Patients with horseshoe kidney and aortic disease may be safely operated upon without damage to the kidney. IVP and selective angiography are essential to provide preoperative information.

The clinical, roentgenologic and laboratory findings in 124 patients with dissecting aneurysm of the aorta are reported. In 53 patients the dissection occurred in the ascending aorta ("proximal" dissection), and in 71 patients the site of origin was the descending thoracic aorta ("distal" dissection). Certain distinct clinical differences between the groups were apparent. Although hypertension was an important predisposing factor, it was significantly more common in distal dissection, as was atherosclerosis. Back pain and hypertension on hospital presentation characterized patients with distal dissection. Conversely patients with proximal dissection were younger and had a significantly higher incidence of Marfan's syndrome, cystic medial necrosis, anterior chest pain, pulse deficits, neurologic compromise, aortic insufficiency and congestive heart failure. In both groups, syncope appeared to correlate well with the occurrence of cardiac tamponade. Chest roentgenograms almost always showed an abnormal aortic contour. Aortic angiography, when performed, was usually confirmatory of the diagnosis.

Prolonged ingestion of mixed analgesics containing phenacetin has been associated significantly with the development of a chronic interstitial nephritis frequently associated with papillary necrosis. This disease is frequently underdiagnosed. If an adequate history of headache and/or backache (of which most of these patients complain) is not taken, the central causative effect of phenacetin ingestion may never be appreciated. Laboratory tests show the usual abnormalities seen in any form of chronic interstitial nephritis such as poor urinary concentration, renal failure with large urine output, and no hypertension. Papillary necrosis is helpful but not pathognomonic. The type of medications ingested appears to be changing to prescription compounds. The with significant improvement in renal function.

Renovascular hypertension is common in nonspecific aortoarteritis (Takayasu disease). The utility of percutaneous transluminal renal angioplasty in managing this disease has been reported infrequently, and technical problems in using this treatment method have not been described. We retrospectively evaluated the results of renal angioplasty in treating 33 stenoses in 20 patients. Each patient's diagnosis was based on the criteria established by the Aortitis Syndrome Research Committee of Japan. Criteria for selection of patients for angioplasty were (1) severe hypertension uncontrolled by single-drug therapy, (2) angiographic evidence of at least 70% stenosis of the renal artery with a pressure gradient of more than 20 mm Hg, and (3) a normal sedimentation rate. The transfemoral route was used to treat all 33 stenoses. Follow-up examinations included blood pressure and medication evaluation 1 day, 1 week, and 4-6 weeks after treatment, and thereafter at 6-month intervals. Technical success was obtained in 28 lesions (85%) in 17 patients (85%). All failures occurred in the presence of coexistent abdominal aortic disease and tight, proximal stenosis of the renal artery. Technical difficulties were attributed to the tough, noncompliant nature of the stenoses, which were difficult to cross and resisted repeated, prolonged balloon inflations. These patients experienced backache and a fall in systemic blood pressure during balloon inflation. In one patient, the ipsilateral renal vein was injured during angioplasty and required surgery. Clinical success was obtained in 14 (82%) of the 17 patients in whom technical success was achieved and included cure in six patients and improvement in eight others. Follow-up 1-18 months (mean, 8 months) after treatment showed restenosis in six (21%) of 28 lesions. We conclude that renal angioplasty in nonspecific arteritis is associated with technical difficulties; however, the short-term results are good and the complication rate is acceptable.

In an effort to determine the relationship between low-back pain and intraosseous hypertension, in vivo vertebral pressure measurements were performed on 19 patients. A cannulated screw was placed percutaneously into the middle of the vertebral body by a transpedicular route. Pressure measurements were recorded with the patient in various positions. Pressures were greatest in the sitting position, lowest in the prone position, and intermediate in the standing position. A correlation was found between intravertebral body pressure and patient position. Pressures were highest in the positions most commonly associated with low-back pain.

We compared the self-reported illnesses (heart disease, back pain, rheumatoid arthritis, hypertension, and pulmonary disease) and smoking histories of 100 cases and 100 controls matched for age and sex with reports of this information from proxy informants from the same household in two areas in the city of Beirut. In addition, both cases and controls were given physical examinations to evaluate the accuracy of the responses. The level of agreement between the responses of subjects and of their informants varied from one condition to the other. Heart disease had the highest level of agreement, with the proportion of agreement greater than 93% for the cases and the controls and having chi values of 0.79 and 1.0, respectively. The report of back pain exhibited the lowest level of agreement, with responses showing a proportion of agreement of 74% for the cases and 90% for the controls, with chi values of 0.49 and 0.50, respectively. In comparing the responses of subjects and proxy informants with the results of physical examinations, heart disease had the highest level of agreement (J index ranged from 0.69 to 0.84), and back pain had the lowest level of agreement (J index ranged 0.42 to 0.48). These results show that proxy informants are good respondents for members of the same household and that health interview surveys are accurate for data collection of well defined chronic conditions.

The size of a thoracic aortic aneurysm (TAA) is an important factor of the operative indication. We experienced a ruptured TAA the diameter of which was only 4 cm. A 71 years old man was admitted due to the severe back pain under the shocked condition. We diagnosed him a ruptured TAA by CT scan. Because he had no progressive anemia and the hemodynamics was very stable, we followed him conservatively. Two months later, the operation was performed. We resected the aneurysm and inserted an aortic prosthetic graft. From the operative findings, the aneurysm was certified as a true aneurysm, and the maximal diameter was only 4 cm. First choice for the treatment of ruptured TAA is the emergent operation. But when the hemodynamics is extremely stable and the anemia does not progress at all, a conservative therapy can be selected. Even if the aneurysm is very small, the control of hypertension is quite important.

To understand the content of ambulatory family practice and find effective ways to improve clinical service, education and research in the Department of Family Medicine of Kaohsiung Medical College Hospital, we surveyed 14,064 patients from Jan. 1984 to Feb. 1991 and analysed (a) their basic demographic data including sex, age, insurance type, source and residential district and (b) clinical health problems covering 25,679 diagnoses and 148,994 diagnostic visits. Clinical health problems were recorded by the ICHPPC-2 code system. Results of basic demographic survey were as follow: 49.1% of patients was male and 50.9% female; 58.9% fell in the age group of 16-40 years and 22.4%, 12.0% and 6.7% of patients fell into the age groups of 41-65, under 16 and over 65 years respectively; 62.8% was insured usually by labor insurance and 26.9% had no insurance; the commonest referrals were other patients, colleagues, company personnel, doctors, media ... etc.; 58.8% lived in Kaohsiung City and 19.6% in Kaohsiung county. As for clinical health problems, the data showed that the commonest thirty diagnoses encountered at our clinic accounted for 69.3% of 25,679 diagnoses and the commonest ten diagnoses in descending order were medical health examination, acute URI, abdominal pain, uncomplicated hypertension, prophylactic immunization, hepatitis B carrier, back pain, anxiety disorder, viral hepatitis and irritable bowel syndrome. By calculating the average value of each diagnosis in a sample of 148,994 diagnostic visits to evaluate the habits of practice, we found that the commonest ten diagnostic visits at clinic in descending order were diabetes mellitus, hypertension involving target organ, uncomplicated hypertension, gout, hyperthyroidism, duodenal ulcer, tuberculosis, lipid metabolism disorder, other peptic ulcer and depressive disorders; all were chronic diseases. We concluded it was very important and helpful for the development of family medicine program and primary care unit to understand the content of their own ambulatory practice.
