A 64-year-old man came to the hospital complaining of recurrent chest pain and shortness of breath for the previous two days. Diagnoses included diabetes mellitus and hypertension for about six years and documented coronary artery disease. He was not compliant with treatment for any of these disorders. The initial 12-lead ECG and rhythm strip are shown below.

A 67-year-old woman with hypertension, diabetes, hypothyroidism and chronic renal failure reported to the hospital for her regularly scheduled hemodialysis, complaining of shortness of breath. Despite fluid removal during her hemodialysis, she remained tachypneic and developed stridor. She was admitted to the hospital for a work-up of a known mediastinal mass, thought to be a goiter. However, she deteriorated over the next several hours and expired. A post-mortem examination confirmed fatal pulmonary emboli. This case illustrates the fact that, while most patients with chronic renal failure are considered to be at low risk for pulmonary emboli, it is often not diagnosed when present. In this paper, we will review the epidemiological data supporting this notion, examine proposed pathophysiological mechanisms, and review the diagnostic approach that should be considered in the setting of chronic renal failure.

A 52-year-old lady with a history of hypertension, dilated cardiomyopathy and diabetes mellitus type 2, presented with severe upper abdominal pain and vomiting of 4 hours duration. Acute pancreatitis was diagnosed based on high serum amylase and an abdominal computerized tomography scan. On the 3rd day she developed fever, increasing abdominal pain and shortness of breath. A repeated computerized tomography scan showed severe pancreatic necrosis and right adrenal hemorrhage.

Increasing evidence suggests that neurohumoral manifestations of heart failure may lead to insulin resistance, predisposing patients with heart failure to the development of glucose intolerance or worsening of existing diabetes. Theoretically, insulin-sensitizing thiazolidinediones (TZDs) should be beneficial in this patient population. A 74-year-old man with well-compensated systolic dysfunction and longstanding type 2 diabetes mellitus treated with glyburide began therapy with rosiglitazone 4 mg/day, which was increased to 8 mg/day after 1 month. Two weeks later he was seen with a 5-kg weight gain, shortness of breath, bibasilar rales, +S3 gallop, and increased jugular venous distention. Twelve days later symptoms worsened, with pulmonary edema on chest radiograph, continued weight gain, and +4 pitting edema resistant to oral diuretics. The patient was admitted to the hospital for exacerbation of heart failure. Five days after discharge he was readmitted for similar symptoms, including an 11.8-kg weight gain. He reported adherence to drug therapy and diet. Rosiglitazone was immediately discontinued and 11 days later the man's weight stabilized to 79 kg and remained between 79 and 80 kg 2 and 3 months after discharge. This case demonstrates that TZDs may precipitate weight gain and pulmonary and peripheral edema in patients with stable heart failure. Earlier reports documented similar symptoms in patients without a history of heart failure. Although current recommendations state that TZDs should not be administered to patients with New York Heart Association class III or IV disease, practitioners should be aware that these adverse effects also may occur in patients with milder forms heart failure as well as those without heart failure.

Pheochromocytoma is a rare entity. When it presents during pregnancy, rapid recognition and diagnosis are crucial in order to avoid the maternal and fetal morbidity and mortality associated with severe, uncontrolled hypertension. Difficulties arise from the differential diagnosis of pre-eclampsia. We report two patients operated on for pheochromocytoma during pregnancy. The first patient developed new-onset hypertension in early pregnancy. Prior to presentation, there had been non-specific signs of endocrine disorder, namely a mild diabetes, but no hypertension requiring medication. The second patient sought medical care for irregular heartbeat, shortness of breath, and fatigue during the 6th week of pregnancy. She was found to be hypertensive; diagnostic evaluation revealed substantially increased catecholamine levels. The diagnosis was made by elevated urinary catecholamines and by MRI scan as well as ultrasonography, both of which demonstrated an adrenal mass. Both patients underwent surgical extirpation of the affected adrenal gland. The procedure was performed laparoscopically in the case of the second patient. Pre-operatively, both patients were pre-treated with alpha-blockade followed by secondary beta-blockade. Patient two also received methyldopa for control of hypertension. Both patients were readily weaned from antihypertensive medications post-operatively, with complete resolution of hypertension within a few hours. Each pregnancy progressed normally to term.

Thrombotic microangiopathy (TMA) is a recognized complication of malignant hypertension (HTN). Such patients have blood pressures > or = 200/140 mmHg but the condition is defined by the presence of papilledema and is frequently complicated by acute renal failure. Here we report two patients with severe HTN (systolic > or = 180 mmHg or diastolic > or = 120 mmHg), TMA, thrombocytopenia, renal failure, and, in one case, neurological changes (4 of 5 manifestations of the TTP pentad). A 50-year-old male with HTN presented with blurred vision, dizziness, headache, confusion, renal failure, and a TMA (PLT = 39 x 10(9)/L and LD = 2,781 normal <600 U/L). On presentation, BP was 214/133 mmHg and an ophthalmic exam demonstrated no papilledema. With HTN control over 7 days, his platelet count rebounded (220 x 10(9)/L), LD declined (1,730 U/L), and mental status improved. A 60-year-old female with diabetes, HTN, Lupus erythematosus, mild chronic anemia, and thrombocytopenia presented with abdominal pain, shortness of breath, renal failure, and a TMA (PLT = 83 x 10(9)/L and LD = 2,929 U/L). Blood pressures were 180-210/89-111 mmHg and ophthalmic exam demonstrated no papilledema. With HTN control over 8 days, her platelet count rebounded (147 x 10(9)/L), and LD declined (1,624 U/L). Although in both cases a diagnosis of TTP was considered because of overlap with the classic diagnostic pentad, neither received plasmapheresis. TTP is a diagnosis of exclusion, where there is no other likely diagnosis to explain the TMA. In cases of severe HTN (with or without papilledema), the diagnosis of TTP should be held in abeyance until the effect of HTN control can be assessed.

In our study we have examined 198 patients admitted to hospital for shortness of breath at rest due to left ventricle failure. We have divided the patients into two groups according to the presence of diabetes mellitus. We have excluded the patients with noncardiac cause of pulmonary congestion, with valvular or congenital heart disease and with acute coronary syndromes. We have evaluated the presence of hypertension, value of blood sugar on admission, systolic and diastolic blood pressure, heart rate and medication given for heart insufficiency. We have also compared two dimensional transthoracal echocardiogaphic examination in diabetics to nondiabetics. Finally we compared hospital mortality in both groups. Diabetes mellitus (all the patients were type 2 diabetics) was present in 94 patients (47,5 %), in the group of diabetics there were 50 women, in nondiabetics 52 women (n.s.). The average age of diabetics was 75,5 +/- 8 years and 76,6 +/- 10,1 years in nondiabetics (n.s.). History of hypertension had 45 nondiabetics (43 %) and 69 diabetics (73,5 %), p < 0.05. Systolic blood pressure was significantly higher in diabetics 151 +/- 20,8 mm Hg to 140,5 +/- 18,4 mm Hg in nondiabetics, p < 0.05. The values of diastolic pressure and heart rate were comparable in both groups. We have not noticed any significant difference in the application of ACE inhibitors, beta blockers and diuretics for heart failure in both groups. Echocardiographic examination revealed the significantly higher ejection fraction of left ventricle in diabetics as well as the thicker septum and posterior wall of left ventricle. These findings support the role of the diastolic dysfunction in pathogenesis of left ventricle failure. In hospital mortality rate was 8,5 % in diabetics and 7,6 % in nondiabetics (n.s.). Our results confirmed that in pathogenesis of left ventricle failure hypertension and elevated systolic blood pressure play the important part. Apart from the complex secondary prevention of ischemic heart disease the correct treatment of hypertension represents the very important part of the prevention of left ventricle failure. The role of the proper compensation of diabetes mellitus in the prevention of left ventricle failure is also discussed.

Symptomatic ascites as a presenting symptom of hypothyroidism is quite rare. In most of the case reports, patients with ascites requiring therapeutic abdominal paracentesis have long-standing hypothyroidism. We present a case of symptomatic ascites in a subject with hypothyroidism following radioiodine therapy for Graves disease. A 70-year-old African-American man presented with increasing weakness, shortness of breath, weight gain, constipation, and abdominal distention. Past history was significant for coronary artery disease, diabetes, hypertension and history of radioiodine therapy for Graves disease 9 months prior to the presentation. He was taking levothyroxine at 50 microg per day for 3 months prior to the presentation. Physical examination findings were significant for puffiness around the eyes, decreased breath sounds at the lung bases, and distended abdomen with free fluid, hung-up reflexes, and cold extremities. The thyroid-stimulating hormone level at the time was 64 with a free T4 less than 0.4 ng/dL. Analysis of the ascitic fluid revealed an exudative effusion with a serum to ascitic fluid albumin gradient of 1.2. The patient required therapeutic abdominal paracentesis twice, with 4 L each time, to relieve the symptoms. Work-up to rule out other causes did not reveal any other relevant abnormality. After initiation of thyroid hormone replacement, the patient responded very well and the ascites resolved within 2 months. We conclude that ascites associated with hypothyroidism is rare but must be recognized early, since thyroid replacement is the definitive therapy.

An 85-year-old woman presented at the emergency ward. She had had shortness of breath for several days and no bowel movements for 3 days. On the day ofhospitalisation she experienced sudden abdominal pain and collapsed as she went to the toilet. She was being treated for multiple conditions, including type-2 diabetes. She appeared to have lactic acidosis. At first, the symptoms were not attributed to metformin because she was receiving a low dose and serum-creatinine concentrations were within the normal range (98 micromol/l). Bowel ischaemia was suspected and surgery was performed but no defects were found. She was subsequently treated for metformin-related lactic acidosis but died shortly thereafter due in part to postoperative complications. Lactic acidosis is a rare side effect of metformin. In this patient, the retrospectively calculated glomerular filtration rate (GFR) was extremely low (23 ml/min). The serum-creatinine concentration was normal because the patient's body weight was low (40 kg). Impaired renal function is a risk factor for metformin-related lactic acidosis. Renal function can appear to be normal when measured by serum-creatinine concentration in older patients with reduced muscle mass, but calculation of GFR often reveals impairment. Metformin is contraindicated in patients with poor renal function. The increasing use of metformin in older patients for the treatment of diabetes mellitus warrants renewed attention to this severe side effect.

To assess the associations between job stress and somatic symptoms and to investigate the effect of individual coping on these associations. In July 2006, a cross-sectional study was conducted during a periodic health check-up of 185 Japanese male office workers (21-66 yr old) at a Japanese company. Job stress was measured by job demand, control, and strain (=job demand/control) based on the Job Content Questionnaire (JCQ). Major somatic symptoms studied were headache, dizziness, shoulder stiffness, back pain, shortness of breath, abdominal pain, general fatigue, sleep disturbance, and skin itching. Five kinds of coping were measured using the Job Stress Scale: active coping, escape, support seeking, reconciliation, and emotional suppression. Comorbidities of hypertension, diabetes, obesity, depression, and anxiety were also evaluated. The most frequently cited somatic symptom was general fatigue (66%), followed by shoulder stiffness (63%) and sleep disturbance (53%). Of the five kinds of coping, only "active coping" was significantly and negatively associated with the number of somatic symptoms. The generalized linear models showed that the number of somatic symptoms increased as job strain index (p=0.001) and job demand (p=0.001) became higher, and decreased as active coping (p=0.018) increased, after adjusting for age and comorbidities. There was no statistical interaction among active coping, the number of somatic symptoms, and the three JCQ scales. Reporting somatic symptoms may be a simple indicator of job stress, and active coping could be used to alleviate somatization induced by job stress.
