Although it is well known that diabetics have high mortality rates due to ischemic heart disease (IHD), controversies still exist about the severity of coronary artery disease in diabetics compared to nondiabetics. We compared coronary arteriographies of 50 diabetics with IHD to those of 50 nondiabetics with IHD. In regard to coronary risk factors, incidence of obesity was significantly higher in diabetics. Incidence of hypertension, hypercholesteremia, hyperuricemia was higher, although not significant, in diabetics. Incidence of smoking was significantly higher in nondiabetics. The diabetic group showed a significantly higher incidence of patients with more than two or three diseased vessels, and a significantly higher number of diseased coronaries with more than 50% stenosis per patient compared to nondiabetics (5.6 +/- 3.7 vs 3.7 +/- 3.2). The distribution of diseased coronaries with more than 75% stenosis showed no difference between diabetics and nondiabetics. The incidence of coronary spasm was significantly lower in diabetics (12% vs 28%). The high incidence of multiple vessel disease in diabetics was thought to be due to other complicated coronary risk factors, especially hypertension and hypercholesteremia.

The obturator nerve passes in close proximity to the inferolateral bladder wall. Transurethral resection of bladder tumors close to these areas may stimulate the obturator nerve, causing violent adductor contraction and possible inadvertent bladder perforation. To avoid this reaction, local anesthetic blockade of the obturator nerve as it passes through the obturator canal is effective to stop adductor spasm during spinal anesthesia. We performed obturator nerve block in 107 cases by use of insulated needle and nerve stimulator, and measured the depth of the obturator nerve and that of the pubic tubercle. Obesity index was positively correlated with the depth of the obturator nerve as well as the pubic tubercle. However, no correlation was found between the obesity index and the difference of the depth of the obturator nerve and the depth of the pubic tubercle. It is suggested that if the needle is advanced in the direction of the obturator canal about 40mm further after reaching the pubic tubercle, the needle reaches the obturator nerve.

During the past ten years, 145 patients (130 with ulcerative colitis and 15 with polyposis) have undergone colectomy and endorectal ileal pull-through operations at the UCLA Medical Center. The mean age of the patients at operation was 22.4 years (a range of seven to 56 years). All of the patients had a two stage operation with temporary ileostomy. Five had an S-shaped reservoir (SR), one patient had a J-shaped reservoir (JR), 12 patients had no reservoir (NR), 97 had a lateral reservoir with the reservoir constructed at the second operation (LR-2) and 30 had a lateral reservoir constructed at the first operation (LR-1). The most common complications were reservoir inflammation, obstruction of the reservoir outlet, stricture of the ileoanal anastomosis, superficial wound infection and sinus tracts extending upward between the rectal muscle cuff and the pull-through segment of ileum. Forty-four patients underwent reoperation for one or more of the complications. Reoperation was performed upon 60 per cent of the patients with SR, 36 per cent with LR-2, 10 per cent with LR-1 and 17 per cent with NR. Of the reoperations, 33 were performed upon the first 50 patients. Only 11 of the last 95 patients required a corrective operation. Of the last 95 patients, 97.5 per cent are currently functioning well. Important features of the operative technique include using a short rectal muscle cuff (5 centimeters or less), constructing a short reservoir (less than 15 centimeters) and having a short reservoir spout (less than 2 centimeters). Although a reservoir reduces fecal urgency and frequency in most instances, patients with obesity, anorectal muscle spasm, severe rectal disease and thick mesentery may be best treated with no reservoir. In our experience, the LR-1 procedure is technically easy to construct, has a low incidence of complications and is the preferred technique.

Clinical criteria for diagnosis of osteoarthritis are not yet formally established; at present, diagnosis is usually made through physical and radiologic examination and evaluation of synovial fluid. Severe trauma and possibly repeated microtrauma, excessive activity, inactivity, and obesity are believed to aggravate symptoms. Treatment objectives are to reduce pain and improve, or at least preserve, function. Antiinflammatory agents provide relief for many patients, although gastrointestinal reactions may accompany their use. Antispasmodics may be helpful for pain caused by muscle spasm, and intraarticular injections of depocorticosteroids are useful for inflammation. Agents that provide analgesia are an appropriate part of the therapeutic program. Patients should be taught to protect weakened joints through use of orthotics, strengthening exercises, and proper body movement and posture. A supportive physician who encourages a healthy life-style and positive outlook will see better physical as well as emotional results with these patients.

From among 899 consecutive patients who underwent their first coronary arteriography, we selected 147 pts with vasospastic angina (VA) and 356 pts with classic angina (CA) and divided them into three different age groups: -49 years old, 50 to 59, and 60-. In these 899 pts, incidences of VA showed no increase with aging. Prevalence of coronary risk factors in CA, such as diabetes, hypercholesterolemia, hypertension, and obesity, was higher than in VA, although prevalence of smoking in CA was lower than in VA. In VA, we found an age-related increase in the incidence of smoking only, in contrast to the other four risk factors. The VA showed no age-related increase in the incidence of complication of fixed coronary stenosis. These findings suggest that aging and atherosclerosis might not play a major role in pathogenesis of VA, although the mere presence of atherosclerosis irrespective of its severity could interact with local susceptibility to spasm, leading to coronary vasospasm.

An epidemiological and clinical study was carried out on 31 patients with spasm of normal coronary arteries. The series comprised 24 males and 7 females aged 30 to 68 years (mean age: 48 years) with isolated resting chest pain (61 p. 100) or with resting and effort chest pains (39 p. 100). Their cardiovascular risk factors were compared to 735 unselected patients with coronary insufficiency undergoing coronary coronary angiography. Abnormalities of lipid metabolism (45 p. 100) and obesity (14 p. 100) were less common but there was a higher incidence of smoking (74 p. 100 compared to 48 p. 100). Sixteen patients had a psychological test: repressed aggressivity and severe anxiety were found in all patients, a state of separation coincided wtih the onset of the illness in 10 of the 16 patients. On admission, 13 patients presented with attacks of Prinzmetal variant angina, with myocardial infarction in 2 cases. Eighteen patients had non-invalidating angina with sporadic attacks. Coronary angiography was normal in 8 patients and showed lesions with less than 50 p. 100 narrowing in the other 23 patients. Mitral valve prolapse was found on left ventriculography in four patients. Exercise electrocardiography was positive in 7 out of 20 patients, and notably in those who had not had effort angina. All patients were treated with calcium antagonist drugs (25 Nifedipine, 6 Diltiazem), the efficacity of which was tested in 20 patients with a control ergometrine test. Thirty patients were followed up for 6 to 46 months (mean: 15 months). The exercise stress tests were repeated in the 7 patients with positive results before treatment and the results were negative in all cases. Twenty three patients were completely pain free or significantly improved, although 25 p. 100 of control tests remained positive (4/16). Six patients continued to have as much chest pain, and three had positive control tests. One patient with a negative control test developed acute myocardial infarction six months later in the territory of the spasm: during hospitalisation the ergometrine test became positive again.

All contributory factors to the unusual occurrence of stroke in young people were evaluated in patients under age 40 admitted to the Stroke Unit of the Austin Hospital in Melbourne, Australia. Over the August 1977 to December 1980 period there were 700 admissions. Of these 14 patients were under the age of 40. There were 7 males and 7 females whose ages ranged from 17-38 years. Each patient was screened for factors which might contribute to premature vascular disease including hypertension, diabetes, smoking, obesity, and hyperlipidemia. In addition, the following tests were performed to exclude an arteritic process: full blood examination; ESR; protein electrophoresis; syphilis serology; and the presence of antinuclear factor. Each of the 14 patients suffered cerebral infarction. A summary of each case is presented in a table. In 9 patients, infarction occurred in the carotid territory of supply. Large cortical infarcts with or without subcortical involvement occurred in cases 1-8, of whom 5 had major vessel occlusion demonstrated angiographically and another had stenosing and ulcerative atheromatous disease at the extracranial carotid bifurcation. In a further 4 patients, infarction occurred within the vertebrobasilar territory and was either confined to the brain stem, the occiptal cortex, or involved both. Angiograms were performed in 2 of these patients and showed irregular narrowing of the vertebral artery which was interpreted as spasm and segmentally narrowing of the basilar artery. The final patient had several ischemic events which included right sided amaurosis fugax, and left frontal, right parieto-occipital and left occipital infarctions. Angiography was normal. All patients survived the stroke and were able to go home. There may be an interrelationship between the pathological findings of Irey et al. (1978) and the effect oral contraceptives (OCs) has on migraine. This is relevant to Case 13. Sustained exposure to OCs may produce the pathological changes described (visible as segmental narrowing angiographically). In 2 patients cerebral infarction was caused by atheromatous or hypertensive occlusive vascular disease. In Case 3 an embolus occluded the middle cerebral artery. Infarction complicating migraine was diagnosed confidently in 4 patients on the basis of typical migrainous symptomatology in the past and accompanying the stroke. Of the 12 patients fully evaluated, there were no cases of polycythemia or thrombocytosis. There were no abnormalities of the clotting factors. Almost every patient had some form of emotional upset, and there were 7 who had significant psychiatric illness and emotional problems of extreme magnitide.

The authors studied 31 cases of coronary artery disease with normal or minimally diseases coronary arteries in black Africans, 29.8% of 104 coronary patients undergoing coronary angiography in this series. These 31 cases comprised 16 cases of infarction, 10 cases of angina, 3 ventricular aneurysms and 2 cases of silent ischemia in diabetic patients. Twenty-five patients were men (80.6%). There were 6 women (19.3%) two of whom presented in the post-partum period. The average age of these patients was 45 years (males: 47.7 years; females: 41.8 years). The following risk factors were noted: smoking (60%), hypertension (25.8%), obesity (29%), diabetes (12.9%), serum cholesterol (average 2.15 g/l), serum triglycerides (average 1.25 g/l). The risk index per patient was 1.29. In comparison with coronary patients with angiographic coronary lesions (n = 73), the patients with normal angiography were significantly younger, comprised more females and had fewer risk factors (especially hypertension and diabetes), though this was not statistically significant. The prevalence of inaugural infarction was 81.2% in the cases of infarction with normal coronary arteries. These infarcts may be complicated by ventricular aneurysm formation. Spontaneous spasm was observed in 3 out of 31 patients (9.6%) at coronary angiography. A provocative test was performed in only 2 cases and 1 was positive. This deserves further study and may have therapeutic implications. The authors emphasise the high incidence of hemoglobin S or C traits (57.1%). These heterozygotic hemoglobinopathies could be a risk factor in these coronary patients with normal coronary angiography.

Atherosclerotic lesions usually occur in the proximal and middle portion of the coronary arteries. Multiple obstructive lesions appearing only in the peripheral branches without lesions in the proximal or distal portion have not been reported. We encountered a patient with ischemic heart disease showing multiple obstruction in the peripheral branches of the right and left coronary arteries without significant stenotic lesions in the proximal or middle portion. This 49-year-old male was admitted to Yamada Red Cross Hospital due to angina pectoris. Coronary risk factors for him included hypertension, abnormal glucose tolerance, smoking habit, and obesity. Laboratory studies showed a complete blood count and normal blood chemistries, as well as thromboplastin and prothrombin times. Coronary angiography showed multiple obstruction or marked stenosis in the distal portion and peripheral branches; there was no stenosis in the proximal and middle portions. Left ventriculography showed severe hypokinesis in the diaphragmatic segment. Biopsy of the left ventricular endocardium showed interstitial fibrosis but showed no abnormalities in the myocardial fibers or cell infiltration to perivascular areas and vascular walls. Coronary angiography after two months showed multiple lesions, as previously observed. Although ischemic heart disease is caused by various types of vasculitis, embolism, coronary spasm, and fibromuscular dysplasia, in this patient, there were no findings suggestive of causes other than atherosclerosis. This case is interesting in terms of rare angiographic findings and its cause.

Coronary angiographic and risk factor (RF) characteristics were analyzed in 133 Japanese patients with ischemic heart disease (IHD) who were less than 40 years old and who had undergone coronary angiography (CAG) during the past 10 years at six university hospitals in the Tokyo area. We compared the coronary angiographic characteristics of the subject group with those of 216 controls with coronary sclerosis detected by CAG who were more than 40 years old (older control group) and the RF characteristics with those of 133 sex- and age-matched volunteers (younger control group). Sixty seven percent of the subjects (89 cases) were diagnosed as having myocardial infarction (MI) and 33% (44 cases) had angina pectoris (AP). Coronary artery disorders in this group consisted of 103 (77%) cases of coronary sclerosis, 20 (15%) cases of coronary spasm and 10 (8%) cases of miscellaneous diseases, eg, possible vasculitis with connective tissue disease, congenital anomalies, etc. The incidences of significant (> or = 75%) sclerotic narrowing in 0 vessels (31%) and 1 vessel (49%) in the subject group were significantly (p < 0.01) higher than those in the older control group, while the incidence of multivessel disease was significantly (p < 0.05) less in the subject group than in the older control group. The incidences of the following coronary risk factors were significantly (p < 0.05) higher in the subjects than in the younger controls: smoking (83% vs 35%), hypercholesteremia (44% vs 10%), obesity (31% vs 9%), hypertension (29% vs 3%), familial IHD (28% vs 7%) and diabetes mellitus (19% vs 2%). Thus, zero- or single-vessel disease predominated in the younger subject group and the prevalence of coronary risk factors was significantly higher in the subject.
