A 56-year-old black woman with diabetes mellitus was admitted for hypoglycemia and confusion. Her past medical history included breast cancer, for which she had undergone a left lumpectomy and then mastectomy for in-breast recurrence. Her oral intake had decreased during the past month because of increasing discomfort from left-sided chest pain. During this period, she continued to take pioglitazone for diabetes at her originally prescribed dose. The patient's mental status improved quickly after taking orange juice and intravenous glucose, but the chest pain persisted. The pain, which was described as an ache along the left costal margin, increased with palpation, deep inspiration, or coughing. She had recently presented with similar complaints at another hospital where she had been prescribed a muscle relaxant that provided no relief from the pain. She also reported a 14-lb weight loss during the previous 3 months, as well as fatigue, weakness, and aches in her legs and arms. She denied fevers, chills, sweats, abdominal pain, nausea, or recent trauma. Laboratory values at the time of admission were: calcium, 11.8 mg/dL; total protein, 11.1 mg/dL; albumin, 3.2 g/dL; creatinine, 1.0 mg/dL; and hematocrit, 29.3%, with a mean corpuscular volume of 89.3. Chest radiography revealed a lytic lesion in the left lateral fourth rib and left humerus (). Serum and urine protein electrophoresis revealed a monoclonal spike in the gamma region consistent with monoclonal gammopathy. The serum spike was quantified at 3.78 g/dL. A skeletal survey showed many small well-defined lytic lesions in the skull (with one 1.5-cm lytic lesion in the upper posterior parietal bone), arms, and legs. A bone scan showed multiple foci of increased uptake in the right and left ribs as well as the proximal portion of the left femur. The peripheral blood smear revealed rouleaux formation () and plasma cells (). What is the diagnosis?

To determine the causes, risk factors and complications of planned extubation failure of critically ill elderly patients, we conducted a prospective study of 175 consecutive patients (> or = 70 years old) admitted with respiratory failure. Thirty-six (21%) failed extubation within 72 h after planned extubation. Compared to a younger age group (< 70 years old) matched for severity of illness, inability to handle secretions (20%) was the most common reason of airway causes leading to extubation failure in the elderly while upper airway obstruction (22%) was the predominant cause in the control group. As for nonairway causes, COPD related hypercapnic respiratory failure accounted for the majority of cases in both groups. After adjusting for severity of illness, elderly patients who required reintubation had a higher risk of developing nosocomial pneumonia. The presence of underlying pulmonary disease (odds ratio (OR), 2.9; 95% confidence interval (CI) 1.2-6.9), length of intubation > 4 days (OR, 4.3; 95% CI 1.8-10.2), and albumin levels < 2.5 g/dl (OR, 2.7; 95% CI 1.2-6.7) were independently associated with extubation failure in the old. Objective measurements of cough strength and secretion volume are needed to reduce the morbidity of elderly patients at risk for extubation failure.

Candesartan cilexetil is the prodrug of candesartan, an angiotensin II receptor antagonist. Candesartan binds selectively and non-competitively to the angiotensin II receptor type 1, thus preventing the actions of angiotensin II. Clinical trials have demonstrated its efficacy at a dose range of 2 to 32 mg once daily in hypertension of all grades, heart failure, in reducing urinary albumin excretion in diabetes mellitus and in coexisting hypertension and renal failure. Pharmacokinetic properties of candesartan cilexetil in elderly patients are not significantly different from those in younger individuals. Hepatic impairment does not change pharmacokinetics of candesartan cilexetil at doses up to 12 mg/day. No dose adjustment is necessary in patients with mild or moderate renal impairment. Tolerability of candesartan cilexetil is not much different from that of placebo. All adverse events are usually of mild to moderate severity and not dose-related. The most common adverse events were headache, upper respiratory tract infection, back pain, and dizziness. The incidence of these adverse effects, as well as of cough, was similar in patients treated with candesartan cilexetil or placebo. The incidence of adverse events in long-term trials was not different from that in short-term trials. Tolerability of candesartan cilexetil does not differ with either age or gender.

This study was designed to compare the short-term (1-y) tolerability and antiproteinuric efficacy of enalapril and valsartan in patients with type 2 diabetes. Forty-two patients with normal renal function or early-stage nephropathy were recruited in Hong Kong and randomized to valsartan 80 mg/day or enalapril 5 mg/day; the doses were increased to 160 mg and 10 mg daily, respectively, as tolerated. Early-morning urine was analyzed for albumin and creatinine and 24-hour urinary albumin excretion at baseline and 1 year after therapy began. Twenty-two patients were randomized to valsartan and 20 to enalapril. The 2 treatment groups were similar in terms of age, sex distribution, and duration of diabetes or hypertension. Blood pressure decreased to a similar extent (-2.5% to -5.0%) with each drug. Similarly, the 24-hour urinary albumin excretion decreased by 5% to 6% with each drug. The albumin-creatinine ratio in early-morning urine samples and plasma creatinine levels decreased in the valsartan group and increased in the enalapril group, but the difference was not significant. Plasma potassium levels were stable in both groups at the end of study. Cough was reported by 7 (35%) patients receiving enalapril and none of those receiving valsartan (P=.003). In conclusion, enalapril and valsartan both reduced blood pressure and albuminuria to a similar extent with 1 year of therapy in Chinese patients with type 2 diabetes and normal renal function or early-stage nephropathy. Fewer adverse events were reported with valsartan, but both drugs appear to be relatively safe.

The characteristics of Pneumocystis carinii pneumonia (PCP) in patients with connective tissue diseases (CTDs) were examined retrospectively. Nine patients were enrolled in this study. Their mean age was 57.1 years. All the patients received a high-dose steroid or immunosuppressant. The onset (mean 6.6 days) of fever, cough, breathlessness, and geographical ground-glass opacities revealed by chest computed tomography was acute. The serum beta-D: -glucan level increased with a simultaneous increase in the Krebs von den Lungen (KL)-6 or surfactant protein D level. The serum immunoglobulin G (IgG) and albumin levels and the peripheral blood lymphocyte count at the onset of PCP were low, but only the serum IgG level decreased significantly. The patients were treated with trimethoprim-sulfamethoxazole or pentamidine isetionate. Six patients died eventually: two patients of progressive respiratory failure, two probably due to a recurrence of the PCP, and two with microbial respiratory infections other than PCP. Five of the six patients required mechanical ventilation. Three patients received secondary prophylaxis and survived. In conclusion, the acute onset was characteristic of PCP in patients with CTDs. High-dose steroids, immunosuppressants, and hypogammaglobulinemia are risk factors; and respiratory failure requiring mechanical ventilation, severe secondary infections, and a lack of secondary prophylaxis are poor prognostic factors. Secondary prophylaxis is recommended for all of these patients.

Imidapril (Tanatril), through its active metabolite imidaprilat, acts as an ACE inhibitor to suppress the conversion of angiotensin I to angiotensin II and thereby reduce total peripheral resistance and systemic blood pressure (BP). In clinical trials, oral imidapril was an effective antihypertensive agent in the treatment of mild to moderate essential hypertension. Some evidence suggests that imidapril also improves exercise capacity in patients with chronic heart failure (CHF) and reduces urinary albumin excretion rate in patients with type 1 diabetes mellitus. Imidapril was well tolerated, with a lower incidence of dry cough than enalapril or benazepril, and is a first choice ACE inhibitor for the treatment of mild to moderate essential hypertension.

Scrub typhus is a mite-borne infectious disease caused by Orientia tsutsugamushi. Acute respiratory distress syndrome (ARDS) is a serious complication of scrub typhus. This study retrospectively reviewed the medical records of 72 patients diagnosed with scrub typhus from January 1998 to August 2006 in Kaohsiung Chang Gung Memorial Hospital in Taiwan. Eight of 72 scrub typhus patients with ARDS were included in the study; the other patients without ARDS were used as controls. The mortality rate for the scrub typhus patients with ARDS was 25%. The eight patients seldom had underlying diseases. Initial presentations of dyspnea and cough, white blood cell count, hematocrit, total bilirubin, and delayed used of appropriate antibiotics use were significant predictors of ARDS. Multivariate analysis showed that albumin, prothrombin time, and delayed use of appropriate antibiotics were independent predictors of ARDS. Identification of these relative risk factors may help clinicians evaluate clinical cases of scrub typhus with ARDS.

To investigate clinical course and outcome of dengue with acute respiratory failure (ARF), and to identify related risk factors for acquiring ARF in dengue, we retrospectively studied 11 dengue patients with ARF. From June to December 2002, a total of 606 adult patients were diagnosed as having dengue. Eleven (1.8%) of 606 dengue patients had complications of ARF. The main causes of ARF were sepsis (n = 6, 54.5%) and upper gastrointestinal (UGI) bleeding (n = 3, 27.3%). The mortality rate was 72.7% (n = 8). Additionally, univariate analysis showed that age, dyspnea, cough, prothrombin time, activated partial thromboplastin time, aspartate aminotransferase, alanine aminotransferase, blood urea nitrogen, creatinine, albumin, renal insufficiency, acute renal failure, acute hepatic failure, UGI bleeding, and combination bacterial infection were significantly predictive variables associated with dengue patients with ARF.

Our aim was to describe the frequency of HIV infection among patients with tuberculosis and compare their characteristics with patients with TB but not infected with HIV. Patients with cough >3 weeks duration attending 8 hospitals in Abuja, Nigeria were screened with smear microscopy and culture and tested for HIV. Chest X-rays were graded by 2 readers. 731 (62%) of 1186 patients had positive cultures and 353 (48%) of these 731 patients were smear positive. 1002 (85%) patients were tested for HIV and 546 (55%) were positive. 53% (329/625) of the culture positive patients and 58% (217/377) of the culture negative patients were HIV positive. Anorexia, weight loss, low BMI (<18.5), haemoglobin (<11 gm/dl) and albumin and high ESR and liver enzymes were more frequently observed among patients with TB coinfected with HIV than in patients without HIV. Coinfected patients had less cavitations and lung involvement on X-rays than patients without HIV. In conclusion, the prevalence of HIV is very high among patients with TB in Abuja, Nigeria. The presence of HIV decreases the sensitivity of smear microscopy and complicates the diagnosis of TB. Selected clinical and laboratory parameters could be used to identify individuals with TB who are likely to be coinfected with HIV.

We describe here hydrothorax that occurred in a patient on continuous ambulatory peritoneal dialysis (CAPD) and highlight the problems of diagnosis and management. A 48 years-old man with history of obstructive uropathy secondary to urolithiasis was stared on CAPD when he reached end-stage renal failure. Two months later, he was admitted with two days history of shortness of breath on exertion and dry cough increasing in supine position. Chest examination was suggestive of right sided pleural effusion confusion confirmed by chest X-ray. Radioisotope Technetium 99m labeled albumin instilled through the peritoneal catheter was detected in the right pleural fluid confirming the peritoneo-pleural leak. The peritoneal dialysis (PD) was discontinued and the patient was switched to hemodialysis. The pleural effusion subsided and has not recurred for the following three years.
