We assessed the possibility of improvements in the management of the potentially fatal acute hyperglycaemic complications of diabetes by a review of all deaths in patients who presented to the Alfred Hospital, Melbourne, with diabetic ketoacidosis or hyperosmolar coma during the 16 years, 1973-1988. All late deaths of patients during hospitalization were included in the mortality data. In the 610 episodes of diabetic ketoacidosis (pH, 7.30 or lower) or hyperosmolar coma (osmolality, 350 mOsmol/kg or greater), only one death occurred as a result of the acute metabolic disturbance--in a patient who had suffered a cardiac arrest before admission to hospital. The over-all mortality rate was 6.2% (38 deaths). The mortality rate was 4.9% (26 deaths) for 528 episodes of diabetic ketoacidosis and 14.6% (12 deaths) for 82 episodes of hyperosmolar coma. Patients with diabetic ketoacidosis who died were older than were those who survived (64 +/- 13 years compared with 40 +/- 21 years, respectively; P less than 0.001). Mortality in patients with hyperosmolar coma did not relate to age, initial blood-glucose level or osmolality. Twelve deaths resulted from bacterial pneumonia and two deaths resulted from aspiration pneumonia. Other major causes of death were mesenteric and iliac thromboses (six cases), myocardial infarction (eight cases) and cerebral haemorrhage (two cases). Of the 26 deaths that were associated with diabetic ketoacidosis, only two deaths--as a result of aspiration pneumonia and bowel infarction, respectively--were assessed as potentially avoidable after the patient's admission to hospital. Eight of the 12 hyperosmolar-coma-associated deaths occurred in newly recognized diabetic patients in whom there were avoidable delays in diagnosis. We conclude that further improvements in outcome will be difficult to achieve, but that efforts should be directed towards the earlier diagnosis of diabetes and the earlier recognition and treatment of associated acute pulmonary and vascular complications.

To assess the meaning of hospital-associated death rates, we studied whether mortality within 30 days of hospital admission (30-day mortality) is more informative than inpatient mortality and whether detailed assessment of additional discharge diagnoses helps in understanding death rates. We examined hospitalizations for elderly Medicare patients with principal diagnoses of stroke, bacterial pneumonia, myocardial infarction, and congestive heart failure; these conditions account for 30.8% of Medicare 30-day mortality. Average hospital stays for these conditions were 99.0% longer, and inpatient mortality was 25.0% higher in New York than in California, but 30-day mortality was 1.6% higher in California. We conclude that inpatient death rates depend on length-of-stay patterns and give a biased picture of mortality. Additional diagnoses such as shock and pneumonia were strongly associated with increased mortality, but Medicare data do not reveal which patients had these conditions at the time of admission. Recorded diagnoses of chronic diseases such as hypertension, diabetes mellitus, obesity, benign prostatic hypertrophy, and osteoarthritis were commonly associated with reduced risk of death; such reduced risk is not clinically plausible. Several lines of evidence suggest that chronic disorders are underreported for patients with life-threatening disorders. We recommend great caution in using discharge diagnoses of comorbid conditions to adjust hospital death rates for clinical differences in the patient populations.

Pulmonary infections can be a major complication of heart transplantation. Bacterial pneumonia has decreased markedly in the last few years among heart recipients receiving cyclosporine as immunosuppressive therapy. Fungal infections of the lung can cause serious problems in the compromised condition of these patients, with several deaths attributed to Aspergillus and Candida. To our knowledge, however, there has been no report of pulmonary mucormycosis in heart transplant recipients. We describe, therefore, a heart transplant patient with insulin-dependent diabetes mellitus who developed serious cavitary pulmonary mucormycosis. Diagnosis was made by transbronchial biopsy, and treatment required both prolonged administration of amphotericin B and surgical resection to effect a cure. The diagnostic problems and therapeutic considerations associated with pulmonary mucormycosis are discussed.

One hundred and thirty-five patients with bacterial pneumonia who had risk factors (alcoholism, chronic obstructive pulmonary disease, corticosteroid therapy diabetes mellitus, advanced age, solid tumours) were randomly allocated in a double-blind fashion to receive either ceftizoxime (2-4 g every 8 h), cefotaxime (1-2 g every 4 h), or latamoxef (2-4 g every 8 h). Of the 84 patients evaluable for efficacy, clinical cure was achieved in 91%, 85%, and 89% of ceftizoxime- (20/22), cefotaxime-(23/27), and latamoxef-treated (31/35) patients, respectively. Adverse reactions occurred in one of 45 ceftizoxime-treated patients, one of 43 cefotaxime-treated patients, and seven of 47 latamoxef-treated patients. Abnormal laboratory values during therapy were seen in 50% of latamoxef-treated and 43% of cefotaxime-treated patients and in 29% of ceftizoxime-treated patients. Hypoprothrombinaemia occurred in five latamoxef-treated patients and one of these patients experienced an episode of haematemesis. In this study, ceftizoxime, cefotaxime, and latamoxef were similarly effective; however, the incidence of side effects was most frequent with latamoxef.

The feasibility of on-site primary care services and their use by human immunodeficiency virus HIV-seropositive and seronegative injecting drug users within an outpatient methadone maintenance program are examined. A 16-month prospective study was conducted within an ongoing cohort study of HIV infection at a New York City methadone program with on-site primary care services. The study group consisted of 212 seropositive and 264 seronegative drug injectors. A computerized medical encounter data base, with frequencies of primary care visits and with diagnoses for each visit, was linked to the cohort study data base that contained information on patients' demographic characteristics, serologic status, and CD4+ T-lymphocyte counts. Eighty-one percent of the drug injectors in the study voluntarily used on-site primary care services in the methadone program. Those who were HIV-seropositive made more frequent visits than those who were seronegative (mean annual visits 8.6 versus 4.1, P < .001), which increased with declining CD4+ T-lymphocyte counts; 79 percent of those who were seropositive with CD4 counts of less than 200 cells per cubic millimeter received on-site zidovudine therapy or prophylaxis against Pneumocystis carinii pneumonia, or both. Common primary care diagnoses for patients seropositive for HIV included not only conditions specific to the human immunodeficiency virus but also bacterial pneumonia, tuberculosis, genitourinary infections, asthma, dermatologic disease, psychiatric illness, and complications of substance abuse; those who were seronegative were most frequently seen for upper respiratory infection, psychiatric illness, complications of substance abuse, musculoskeletal disease, hypertension, asthma, and diabetes mellitus. Vaginitis and cervicitis,other gynecologic diseases, and pregnancy were frequent primary care diagnoses among both seropositive and seronegative women.

Recently, it has been recognized that oral infection, especially periodontitis, may affect the course and pathogenesis of a number of systemic diseases, such as cardiovascular disease, bacterial pneumonia, diabetes mellitus, and low birth weight. The purpose of this review is to evaluate the current status of oral infections, especially periodontitis, as a causal factor for systemic diseases. Three mechanisms or pathways linking oral infections to secondary systemic effects have been proposed: (i) metastatic spread of infection from the oral cavity as a result of transient bacteremia, (ii) metastatic injury from the effects of circulating oral microbial toxins, and (iii) metastatic inflammation caused by immunological injury induced by oral microorganisms. Periodontitis as a major oral infection may affect the host's susceptibility to systemic disease in three ways: by shared risk factors; subgingival biofilms acting as reservoirs of gram-negative bacteria; and the periodontium acting as a reservoir of inflammatory mediators. Proposed evidence and mechanisms of the above odontogenic systemic diseases are given.

Although there have been substantial evidences on the usefulness of electrolytes for the diagnosis of disease, the evidences for a direct link between serum sodium and serum potassium in relation to a specific disease are very limited. This study was performed to investigate an association between diseases and Na:K ratios in dogs. From January 1997 to December 1999, a total of 39 cases with an Na:K ratio less than 27 were retrieved from the medical records of Veterinary Medical Teaching Hospital, Seoul National University. Ten dogs (25.6%) had a renal or urinary disease, and six (15.4%) had a parasitism. Other miscellaneous diseases included deep pyoderma, grade III patellar luxation, bacterial pneumonia, diabetes, pancreatitis, and pyometra. The Na:K ratio was significantly lower in dogs with renal failures than those with parasitic diseases (p=0.0735). With the criterion of the Na:K ratio < 27, twenty seven dogs (69.2%) had hyperkalemia, whereas thirteen dogs (33.3%) had hyponatremia. Of 13 dogs with Na:K ratios between 20 and 24, six were diagnosed as a renal or urinary tract disease, two as diabetes, and two as a parasitism. The Na:K ratios of 9 dogs were < 20, being with the most prevalent with the disease of renal failures (55.6%). The serum Na:K ratios were more closely related to serum potassium concentrations ( gamma= -0.8710) than serum sodium concentrations ( gamma=0.4703). Two dogs with diabetes had an electrolyte pattern of hyperkalemia with normonatremia. Further studies are needed to determine the usefulness of Na:K ratio for diagnosis of hypoadrenocorticism, and to establish a relationship between patellar luxation and electrolyte unbalance.

In this case, a 65-year-old man complained of fever and productive cough while being treated for diabetes mellitus at the outpatient clinic. His chest CT scan revealed multiple infiltrative lesions in both the right and left lower pulmonary lobes. He was therefore given an antibiotic on suspicion of having bacterial pneumonia, and he also received nutritional instruction in relation to diabetes mellitus, and remission resulted. However, he could not maintain sufficient glycemic control thereafter, and his pulmonary lesions persisted. Because his lesions changed into cavitied multiple nodular lesions, as seen on a chest CT scan, a transbronchial lung biopsy was performed. Histopathological examination of the biopsy specimen demonstrated Cryptococcus organisms, and the Cryptococcus antigen titer was high, which led to a diagnosis of pulmonary cryptococcosis. After oral treatment with fluconazole for 1 year and 4 months, only a small nodule in the right lower lobe and a funicular lesion in the left lower lobe remained on a chest CT scan, and the patient had neither subjective symptoms nor evidence of inflammation, although he still had a positive antigen titer for Cryptococcus. Thus, the treatment was terminated. Improvement of the clinical symptoms and of the laboratory and radiological findings demonstrated the therapeutic efficacy of this treatment.

Recently, it has been recognized, that oral infection especially periodontitis may affect the pathomechanism and course of a number of systemic diseases, such as: cardiovascular, cerebrovascular diseases, atheromatous peripheral vascular disease bacterial pneumonia, diabetes mellitus, osteoporosis, or cause adverse pregnancy outcome. This review will focus on the current knowledge linking periodontal infections to a set of above mentioned systemic diseases. While a number of their mutual interactions have been already identified, additional research will be required to determine with certainty, whether these associations are casual or coincidental and to evaluate disease pathogenesis and potential therapeutic interventions.

Tumor necrosis factor (TNF) inhibitors, such as infliximab (INF) and etanercept (ETA), are highly effective in patients with active rheumatoid arthritis (RA), but have the potential of serious toxicity. For evaluation of treatment with TNF inhibitors, RA patients should be determined for the ACR core set of measures, including tender joint count, swollen joint count, pain score, patient global assessment, physician global assessment, patient-reported functional disability, and acute phase reactants (ESR and CRP), and more practically for the 28-joint Disease Activity Score (DAS28) within the first 3-6 months, and the efficacy could be assessed using the ACR preliminary criteria and the EULAR criteria. Post-marketing surveillance of INF and ETA in Japan indicated that the most serious adverse effects were bacterial pneumonia, pneumocytosis, and interstitial pneumonia, as well as tuberculosis. Infections must be carefully monitored in the patients, particularly those with > or =65 years of age, diabetes, and pulmonary disease. So far no clinical predictors of response to TNF inhibitors have been identified, but genetic variation in the HLA-DRB1 and the LTA-TNF regions was shown to influence the response.
