The aim of this prospective study was to determine the efficacy and safety of levofloxacin in the treatment of community-aquired pneumonia (CAP) in outpatient with ineffective antibiotic management, requiring hospitalization. The examined group included 25 patients (11 M, 14 F) of mean age 70+/-17,5 years with abnormalities in X-ray on admission to hospital. Risk factors for pneumonia and previous antibacterial therapy were analyzed. In the hospital they were treated for 7 days with levofloxacin 500 mg twice a day administred intravenously. Body temperature, blood cell count, ESR, CRP, AST, ALT, LDH, CPK, creatine, urea, potassium, sodium, ABG, and ECG were measured on admission and in the 3-rd and 7- th day of therapy. The chest X-rays were performed and analyzed on hospital discharge. 18 patients were aged > 65 yrs, cardiovascular diseases co-existed in 14, COPD in 9, smoking habit in 12, renal failure in 3, diabetes in 3 and alkohol addiction in 1 cases. On admission 4 patients had respiratory failure, 10 hypoxaemia. During therapy a decrease of body temperature (p<0,001), concentration of CRP (p<0,004) and LDH (p<0,03), CPK (p<0,04) and increase of PaO2 (p<0,012) were observed. The changes of other parameters were not statistically significant. We did not observe any changes in ECG. On discharge from the hospital in 16 patients complete regression and in 6 patients partial regression of lesions in chest X-ray examination were observed. In 3 patients levofloxacin therapy was noneffective: in 2 because of persistent high body temperature after 3 days of treatment and in 1 patients because of recurrent of fever. Adverse events were mild. Transient exacerbation of renal failure was observed in 3 patients. Our study demonstrates that levofloxacine ni dose 2x500 mg given intravenously for 7 days is effective and safe in treatment of CAP in patients with previously ineffective antibacterial therapy.

Chronic hypoxia is related to many pathological conditions: aging, heart and respiratory failure, sleep apneas, smoke, chronic obstructive pulmonary disease (COPD), diabetes, hypertension and arteriosclerosis, all characterized by reductions of sleep-related erections (SREs) and by erectile dysfunction (ED). Sleep-related erections occur naturally during rapid eye movement (REM) sleep in sexually potent men. Hypoxia is also a physiological condition at altitude. The level of inspired oxygen decreases progressively with the increase of altitude; for this reason, this study was performed to evaluate the relationship of SREs with hypoxic environment. SREs have been recorded by an erectometer (RigiScan) on three mountain climbers (mean age: 32.5) during a 26-day stay at an altitude ranging from 2000 to 5600 m above sea level. Twenty-four records have been made at progressively increasing altitudes. A data analysis was carried out on a statistical mean of the three values of each variable and an analysis of variance (ANOVA) and Newman-Keuls test were carried out for multiple comparison among groups. At altitudes over 4450 m, we found lack of rigidity at 80-100% and 60-79%. Mean % of rigidity and rigidity time of 80-100% (tip and base) decreased progressively with altitude. No significant reductions were shown in rigidity time at 0-19% and at 20-39% (tip and base), of total number, of total and mean duration of SREs. Pathological rigidometric records at high altitude in sexually potent men at sea level clarify the primary role of hypoxia in physiopathological ED pathway.

A 65-year-old man with diabetes mellitus reporting fever and urination disturbance on a flight from Bangkok back to Japan in July 2003 was admitted elsewhere for acute prostatitis. Despite intravenous antibiotics, his condition deteriorated. On admission to our hospital, he suffered from respiratory failure, with laboratory data showing disseminated intravascular coagulation (DIC). Computed tomography (CT) shows infiltrative and nodular shadows in both lung fields and low-density areas in the left kidney and prostate gland, consistent with pneumonia and abscesses in these organs. He also developed broad osteomyelitis in the right lower extremity with cellulitis and arthritis in the right hand, knee, and foot. Blood, urine, and joint fluid culture all yielded Burkholderia pseudomallei, so he was diagnosed with melioidosis. Treatment was started with meropenem and minocycline, then meropenem was changed to imipenem. His symptoms gradually improved after ciprofloxacin was added, so all intravenous antibiotics were discontinued and he underwent oral treatment with chloramphenicol, minocycline, and sulfamethoxazole/trimethoprim in September 2003. He developed fever again, however, and oral therapy was discontinued and intravenous antibiotics restarted. After resolution of fever, oral maintenance therapy was initiated again with levofloxacin and minocycline in October, and his condition remained stable. After discharge in April 2004, he has been followed up with no evidence of relapse. This is considered to be the seventh case of melioidosis reported in Japan. Our patient manifested multiple organ lesions with sepsis and DIC, and was difficult to treat, but clinical symptoms improved in long-term antibiotic administration. With travelers to Southeast Asia increasing, greater attention must be paid to imported infectious diseases, such as melioidosis.

Little is known about the incidence and clinical outcomes of infective endocarditis (IE) involving native valves in Asian countries. This nationwide study investigated epidemiologic features and in-hospital mortality associated with IE in adults (age > or =18 years) based on Taiwan's National Health Insurance database from 1997 through 2002. Of 7,240 enrolled patients with IE involving native valves, the mean age was 53 +/- 19 years and 70% were men. The mean annual crude incidence was 7.6 per 100,000 inhabitants. The incidence was significantly higher in men than in women (10.4 vs 4.6 per 100,000; p <0.001). The incidence of IE increased steadily with age, ranging from 3.8 per 100,000 persons in patients <30 years of age to 33 per 100,000 persons in patients > or =80 years of age (p <0.001). Staphylococcal (32%) and streptococcal species (61%) were the most common causative pathogens. The mean in-hospital mortality rate was 18%. Multivariate analysis showed that male gender, older age (> or =50 years), diabetes mellitus, heart failure, neurologic complications, renal insufficiency, respiratory failure, shock, and Staphylococcus species as the causative microorganism were independent predictors of in-hospital mortality. In conclusion, this Taiwanese study revealed a high incidence of IE in men and elderly subjects. The in-hospital mortality rate remained high. Patients with IE who also developed shock and respiratory failure were the most likely to have a poor outcome.

Solitary fibrous tumor of the pleura (SFTP) is rare. A 73-year-old man, without past history of diabetes mellitus, was admitted to hospital with profound hypoglycemia, loss of consciousness and respiratory failure. CT indicated a huge heterogenous mass lesion (12 x 12 x 17 cm) at the right thoracic cavity with total atelectasis of the right lower lung. He underwent a standard thoracotomy with complete excision of the tumor. Pathology indicated malignant SFTP with insulin-like growth factor-binding protein-2 production. There were no further incidences of hypoglycemia or respiratory failure after excision of the tumor. Hypoglycemia resulting from a solitary fibrous tumor is uncommon. Standard thoracotomy and complete resection of this giant tumor provided a good result for the present patient.

Sarco(endo)plasmic reticulum (SER) Ca2+ ATPases represent a highly conserved family of Ca2+ pumps which actively transport Ca2+ from the cytosol to the SER against a large concentration gradient. In humans, 3 genes (ATP2A1-3) generate multiple isoforms (SERCAla,b, SERCA2a-c, SECA3a-f) by developmental or tissue-specific alternative splicing. These pumps differ by their regulatory and kinetic properties, allowing for optimized function in the tissue where they are expressed. They play a central role in calcium signalling through regenerating SER Ca2+ stores, maintaining appropriate Ca2+ levels in this organelle and shaping cytosolic and nuclear Ca2+ variations which govern cell response. Defects in ATP2A1 encoding SERCA1 cause recessive Brody myopathy, mutations in ATP2A2 coding for SERCA2 underlie a dominant skin disease, Darier disease and its clinical variants. SERCA2a expression is reduced in heart failure in human and in mice models. Gene-targeting studies in mouse confirmed the expected function of these isoforms in some cases, but also resulted in unexpected phenotypes: SERCA1 null mutants die from respiratory failure, SERCA2 heterozygous mutant mice develop skin cancer with age and SERCA3 null mice display no diabetes. These unique phenotypes have provided invaluable information on the role of these pumps in specific tissues and species, and have improved our understanding of Ca2+ regulated processes in muscles, the heart and the skin in human and in mice. Although the understanding of the pathogenesis of these diseases is still incomplete, these recent advances hold the promise of improved knowledge on the disease processes and the identification of new targets for therapeutic interventions.

Oxidative stress plays an important role in aging and various diseases such as cancer, cardiovascular diseases, diabetes mellitus and bronchial asthma. However, little is known about a potential role of oxidative stress in the pathogenesis of severe motor and intellectual disabilities (SMID) in terms of respiratory disturbance, which is the most common complication. In the present study, we examined the urinary levels of oxidative stress markers, 8-hydroxy-2'-deoxyguanosine (8-OHdG), hexanoyl-lysine adduct (HEL) and acrolein-lysine adduct (ACR) in patients with SMID. The mean level of urinary 8-OHdG in SMID patients was significantly higher than that in normal controls (18.8 +/- 9.0 ng/mg Cre and 10.5 +/- 2.9 ng/mg Cre, respectively) (p < 0.01). There was no significant difference of the mean level of urinary HEL between patients with SMID and normal controls (81.9 +/- 40.3 pmol/mg Cre and 69.2 + /-37.7 pmol/mg Cre, respectively), while the mean level of ACR in patients with SMID was higher than that of normal controls (220.5 +/- 118.6 nmol/mg Cre and 144.9 +/- 62.0 nmol/mg Cre, respectively) (p < 0.05). In addition, the level of 8-OHdG was strongly correlated with the severity of respiratory disturbance evaluated as the respiratory disturbance score (RDS) (Spearman r = 0.73, n = 14, p < 0.01). In contrast, there was no correlation between the levels of these oxidative stress markers and age or medication of antiepileptic drugs. These results suggest that urinary 8-OHdG is a potentially useful biomarker for evaluating the severity of respiratory failure in patients with SMID.

Pancreatic agenesis is a rare cause of neonatal diabetes mellitus (NDM). It can be associated with malformations of the heart, the biliary tract, and the cerebellum. We report an infant with NDM because of pancreatic agenesis, intra-uterine growth retardation, dysmorphic features, and recurrent bacterial infections. He was born to healthy consanguineous parents. With adequate replacement of insulin and pancreatic enzymes, his blood glucose levels were controlled and his weight slowly increased. However, he continued to develop recurrent serious bacterial infections and died at the age of 11 months with sepsis and respiratory failure. Analysis of the PTF1A and PDX1 genes, which have been associated with congenital agenesis of the pancreas, did not reveal any mutation. Genetic abnormalities of chromosome 6 associated with transient neonatal diabetes as well as mutations in the KCNJ11 and ABCC8 genes encoding the pancreatic potassium channel were also excluded as a cause of the NDM in this patient. The association of permanent neonatal diabetes because of pancreatic agenesis, dysmorphism, and non-specific immunodeficiency is previously undescribed and may represent a new possibly autosomal recessive syndrome.

An 82-year-old male Bangkokian with hypertension, diabetes mellitus, end-stage renal disease, and coronary artery disease for many years, was hospitalized due to deterioration of a 3-day influenza-like-illness with one-day chest oppression and respiratory failure. At the emergency room, oxygen saturation was 79% on room air Chest X-ray revealed bilateral diffuse pulmonary infiltrates. He was intubated and hemodialysis was initiated. Emergency coronary angiography revealed patent coronary artery. Sputum gram stain revealed numerous leukocytes with no bacteria. On day three of hospitalization, empiric treatment with oseltamivir and clarithromycin was administered Seventy-two hours later his clinical condition began to improve and fever subsided 7 days later Rapid test of tracheal secretion with immunofluorescence assay was positive for moderate amount of influenza A virus. Viral isolation yielded influenza A virus subtype H1N1. Review of in-patient records at this hospital using ICD-10 codes as J10 and J11 during 1995-2005, discovered 32 cases with claim diagnosis of influenza. However this is the first case with proven influenza pneumonia that was given empiric oseltamivir. Rapid deterioration of influenza-like illness due to human influenza virus in the elderly and pathogenesis of pulmonary in this case are discussed to alert physicians to recognize this dreadful illness and treat it in timely fashion.

Leigh syndrome (also termed subacute, necrotizing encephalopathy) is a devastating neurodegenerative disorder, characterized by almost identical brain changes, e.g., focal, bilaterally symmetric lesions, particularly in the basal ganglia, thalamus, and brainstem, but with considerable clinical and genetic heterogeneity. Clinically, Leigh syndrome is characterized by a wide variety of abnormalities, from severe neurologic problems to a near absence of abnormalities. Most frequently the central nervous system is affected, with psychomotor retardation, seizures, nystagmus, ophthalmoparesis, optic atrophy, ataxia, dystonia, or respiratory failure. Some patients also present with peripheral nervous system involvement, including polyneuropathy or myopathy, or non-neurologic abnormalities, e.g., diabetes, short stature, hypertrichosis, cardiomyopathy, anemia, renal failure, vomiting, or diarrhea (Leigh-like syndrome). In the majority of cases, onset is in early childhood, but in a small number of cases, adults are affected. In the majority of cases, dysfunction of the respiratory chain (particularly complexes I, II, IV, or V), of coenzyme Q, or of the pyruvate dehydrogenase complex are responsible for the disease. Associated mutations affect genes of the mitochondrial or nuclear genome. Leigh syndrome and Leigh-like syndrome are the mitochondrial disorders with the largest genetic heterogeneity.
