ABSTRACT
It is common to see patients with atherosclerotic coronary disease and peripheral arterial disease in routine clinical practice. One needs to have a comprehensive and integrated multi-speciality approach and panvascular revascularization in such patients. We report a 54-year-old diabetic hypertensive male with extensive atherosclerotic coronary and peripheral arterial disease, who presented with congestive heart failure, claudication of both lower limbs and mesenteric ischemia. He underwent successful percutaneous panvascular revascularization of coronary, renal, mesenteric, aorto-iliac and superficial femoral arteries. Long-term patency of all the stents was also documented.
ABSTRACT
INTRODUCTION: Heroin overdose can cause various rare neurological complications like spongiform leukoencephalopathy, seizures, stroke, toxic amblyopia, transverse myelopathy, mononeuropathy, plexopathy, acute inflammatory demyelinating polyradiculoneuropathy, rhabdomyolysis, compartment syndrome, fibrosing myopathy, and acute bacterial myopathy. We report here the simultaneous presentation of multiple complications of heroin toxicity. CASE REPORT: A young heroin addict was found unarousable lying in the lotus posture. Examination showed quadriplegia and left leg gangrene. He subsequently developed heroin-induced transverse myelitis, rhabdomyolysis, left leg compartment syndrome, and myoglobin-induced acute renal failure. DISCUSSION: This case leads us to consider a common linked or systemic mechanism of injury rather than a local mechanism when multiple simultaneous organ failure occurs complicating heroin abuse.

Cardiovascular events are the principal cause of mortality in patients with chronic kidney disease (CKD). Secondary hyperparathyroidism (SHPT), a common complication of CKD, contributes to cardiac dysfunction. This study is an attempt to demonstrate the effects of parathyroid hormone suppression with oral calcitriol on cardiovascular hemodynamics. Twenty predialysis CKD patients with SHPT were given calcitriol therapy for 12 weeks. Ten similar patients received placebo. Echocardiographic assessment of cardiac function was performed at baseline and after 12 weeks of treatment. Calcitriol therapy effectively suppressed SHPT. Baseline left ventricular (LV) end diastolic diameter and LV end systolic diameter were 4.86+/-0.48 and 2.86+/-0.33 cm, and the mean FS was 41.02+/-4.79%. Left ventricular end systolic and end diastolic volumes were normal (42.30+/-9.07 and 91.40+/-19.68 mL). The ejection fraction was slightly reduced (53.54+/-3.57%). Pretreatment Doppler indices including E velocity (0.816+/-0.087 m/s), A velocity (0.696+/-0.089 m/s), and E/A ratio (1.193+/-0.210) were significantly impaired. After 12 weeks of calcitriol therapy, there was no significant change in the LV dimensions or ejection fraction, but there was a significant improvement in the diastolic parameters, namely the A velocity (0.680+/-0.084) and E/A ratio (1.238+/-0.180). Secondary hyperparathyroidism is an important factor in the pathogenesis of cardiovascular complications in CKD. There is evidence to support that correction of hyperparathyroidism can improve the systolic dysfunction seen in advanced kidney disease. This study shows that diastolic dysfunction seen in predialysis CKD patients may also be possibly improved with calcitriol therapy.

Anemia is common with connective tissue disorders, but pancytopenia is rare. We report a 22-year-old female who presented with menorrhagia, seizures, anemia, leukocytosis, thrombocytopenia, pericardial effusion, positive ANA, and evidence of vasculitis on CT head scan and was diagnosed with systemic lupus erythematosus (SLE). After 7 months of remission, she was readmitted with menorrhagia and pancytopenia. Investigations revealed aplastic anemia. She survived on transfusion support for 6 weeks, during which period she received methylprednisolone and cyclophosphamide pulses, and phenytoin was omitted but to no avail. Cyclosporine (300 mg/day) was started and the aplastic anemia responded. After 4 months of therapy, the cyclosporine was gradually tapered over the next 2 months. The patient has been on 10 mg/day of prednisolone for the last 6 months. Aplastic anemia is rare in SLE and the response to immunosuppressants is variable, but here is a success story.

A 34-year-old female with end-stage renal disease was admitted for severe metabolic acidosis, uremic encephalopathy, pericarditis and severe anemia following a bout of acute gastroenteritis. She improved on aggressive medical management including intensive hemodialysis and was initiated onto maintenance heparin-free hemodialysis (twelve hours per week) and discharged. After a week, she presented with fever with chills and rigors for three days, was toxic, severely orthopenic and had a pulsus paradoxus of 36 mmHg. Echocardiography suggested cardiac tamponade. Aspiration revealed frank pus with polymorphonuclear predominance and Staphylococcus aureus on culture. CT of the thorax revealed pericardial effusion. In the absence of any obvious septic foci, concomitant pleuro-pulmonary sepsis, mediastinal or intra-abdominal pathology; a diagnosis of "acute primary purulent pericarditis" was made. Patient was put on parenteral antibiotics-ceftriaxone and metrogyl. Vancomycin was added after sensitivity results. Pericardial drainage was required initially. After toxemia improved, paradox decreased and fever subsided, the pericardial catheter was removed and antibiotics continued for a period of four weeks. Maintenance hemodialysis was continued during hospital stay and after discharge.
