Streptococcus suis, a major global porcine pathogen, is an emerging zoonosis in Southeast Asia that triggered a 2005 outbreak in China. S. suis causes meningitis, sepsis, and endocarditis in both pigs and humans and involves significant mortality. We report the case of a previously healthy 50-year-old dairy farmer who developed S. suis type 2 endocarditis complicated by pulmonary embolism and spondylitis. He experienced a high fever, chills, fatigue, and worsening low back pain in the 6 weeks prior to admission. On physical examination, he had lumbar spine tenderness and weakness of the left leg. Blood culture identified penicillin-sensitive S. suis type 2. Echocardiography showed vegetation on the tricuspid valve, and magnetic resonance imaging (MRI) showed signs of spondylitis. The man reported sudden chest pain several days after admission, which computed tomography (CT) showed what was diagnosed as a septic pulmonary embolism. He was treated with penicillin G for 4 weeks and gentamicin for the first 2 weeks, followed by 2 weeks of oral amoxicillin, after which his symptoms gradually improved. The infection source was probably his dairy herd, since calves often bit his fingers while feeding and S. suis was found in their oral mucus. Over 400 cases of human S. suis infection have been reported globally, but this is, to our knowledge, the first known case of bovine transmission. All of Japan's 8 other cases involved occupational swine exposure, 5 of whom had injuries to their fingers. This emerging situation should be made known to all possibly involved in unprotected direct contact with swine and cattle, particularly when the skin could be compromised by cuts or abrasions.

This flu season, health care providers must be prepared to treat patients who have the seasonal flu and also those who have contracted a novel strain of the H1N1 influenza virus. Although H1N1 flu is sometimes incorrectly called "swine flu," the virus is transmitted from person to person; it cannot be contracted from pigs or from eating pork products. Symptoms of the H1N1 flu include fever, chills, nausea, vomiting, body aches, lethargy, and fatigue, which usually appear in rapid succession. People at high risk include children, pregnant women, and those with certain medical conditions. The most common cause of death from the virus is respiratory failure, but other causes of mortality include sepsis, dehydration, and electrolyte imbalance. The first line of defense against H1N1 flu is vaccination. Treatment includes use of antiemetics, antipyretics, and respiratory support.

A 64-year old hospitalized male for severe bronchial asthma began to complain fatigue and appetite loss. His asthma had been treated with oral bethamethasone. The Chest CT at this time revealed a bilateral consolidation of the lower lung. Despite a week of treatment with antibiotics and anti-fungals, the patient expired from DIC progression. His premortem sputum and blood culture grew Cryptococcus Neoformans. We concluded his diagnosis as cryptococcal pneumonia and sepsis. Sepsis by Cryptococcus neoformans is a rare clinical event, and only 20 cases have been reported in Japan. Although 16 of the 20 had preexisting medical conditions, a case with underlying bronchial asthma has never been reported. A comparison of the reported cases of the US and Europe to that of Japan revealed differences in the patients' underlying conditions. We report a case with a brief review of the literature and summarize the 20 cases that have been reported in Japan.

Sphingomyelinase (SMase) hydrolyzes membrane sphingomyelin into ceramide, which increases oxidants in nonmuscle cells. Serum SMase activity is elevated in sepsis and heart failure, conditions where muscle oxidants are increased, maximal muscle force is diminished, and fatigue is accelerated. We tested the hypotheses that exogenous SMase and accumulation of ceramide in muscle increases oxidants in muscle cells, depresses specific force of unfatigued muscle, and accelerates the fatigue process. We also anticipated that the antioxidant N-acetylcysteine (NAC) would prevent SMase effects on muscle function. We studied the responses of C2C12 myotubes and mouse diaphragm to SMase treatment in vitro. We observed that SMase caused a 2.8-fold increase in total ceramide levels in myotubes. Exogenous ceramide and SMase elevated oxidant activity in C2C12 myotubes by 15-35% (P < 0.05) and in diaphragm muscle fiber bundles by 58-120% (P < 0.05). The SMase-induced increase in diaphragm oxidant activity was prevented by NAC. Exogenous ceramide depressed diaphragm force by 55% (P < 0.05), while SMase depressed maximal force by 30% (P < 0.05) and accelerated fatigue--effects opposed by treatment with NAC. In conclusion, our findings suggest that SMase stimulates a ceramide-oxidant signaling pathway that results in muscle weakness and fatigue.

Fatigue is a common symptom of advanced cancer limiting one's activity and affecting the quality of life. It is a multidimensional symptom complex with subjective and objective components. Hence, its definition and assessment seems arbitrary, incomplete, and elusive. Components of fatigue often merge with other 'disease states' as anemia, depression and so on, compounding difficulty to assess it separately. Fatigue has a high prevalence rate, and lasts longer in chronic diseases like cancer. Its association with treatment modalities like chemotherapy, radiotherapy alongside the primary disease process makes it seemingly ubiquitous in many cases. Systemic manifestation of cancer causes excess demand on body resources on cell repair, uncontrolled growth with metabolite accumulation causing fatigue. Co-morbid conditions of organic and psychological nature causes fatigue. There are many assessment tools for fatigue with different uses and objectives, simple and reproducible tools like Brief Fatigue Inventory, Edmonton Symptom assessment scale seem feasible in everyday practice. Management of fatigue is not straightforward and rewarding. Although treatment of cause appears to be an attractive option, it is not possible in all cases. Therapeutic agents targeting cytokine load is in early stages of study and available results are not favorable. Specific measures aimed at pain relief, prevention/treatment of sepsis, management of depression, avoidance of drugs causing fatigue, restoring the metabolic profile are important. Methyl phenidate, megestrol, and modafinil are some drugs with promising effect to treat fatigue, though confirmatory studies are yet to be established. Non-pharmacological methods are also helpful. Forewarning patients on upcoming fatigue, active regular exercise, and stress management are some of them. Fatigue being a multidimensional entity, single mode of therapy is insufficient. Combined modality tailored to individual patient need and understanding may be the right way to battle this ill-understood symptom. This review article examines the etiopathogenesis and management strategies of fatigue in cancer.

The systemic capillary leak syndrome (SCLS) is a rare disease of reversible plasma extravasation and vascular collapse accompanied by hemoconcentration and hypoalbuminemia. Its cause is unknown, although it is believed to be a manifestation of transient endothelial dysfunction due to endothelial contraction, apoptosis, injury, or a combination of these. Fewer than 150 cases of SCLS have been reported, but the condition is probably underrecognized because of its nonspecific symptoms and signs and high mortality rate. Patients experience shock and massive edema, often after a nonspecific prodrome of weakness, fatigue, and myalgias, and are at risk for ischemia-induced organ failure, rhabdomyolysis and muscle compartment syndromes, and venous thromboembolism. Shock and edema reverse almost as quickly as they begin, at which time patients are at risk for death from flash pulmonary edema during rapid fluid remobilization. Diagnosis is made clinically and by exclusion of other diseases that cause similar symptoms and signs, most notably sepsis, anaphylaxis, and angioedema. Acute episodes are treated with vasopressor therapy and judicious fluid replacement, possibly with colloid solutions for their osmotic effects, to prevent the sequelae of underperfusion. Between episodes, patients may be treated with theophylline and terbutaline, which clinical experience suggests may reduce the severity and frequency of acute episodes. Prognosis is uncertain, but patients who survive an initial severe SCLS episode are estimated to have a 10-year survival rate greater than 70%. Much remains to be learned about SCLS, and clinicians should consider the diagnosis in patients with unexplained edema, increased hematocrit, and hypotension.

Clinicians are becoming more aware of the risks of sleep deprivation and unrecognized sleep-disordered breathing in hospitalized patients, most importantly in those patients planning to undergo surgical procedures. Polysomnography is difficult to perform in the hospital setting, such that actigraphy or urinary metabolites of melatonin are often used as surrogate measures, and show that sleep is markedly impaired. Patients in the medical intensive care unit with sepsis or requiring mechanical ventilation may show complete absence of the normal circadian rhythm pattern, and many centers have initiated sleep-enhancement protocols. In postoperative patients, rapid-eye-movement sleep is nearly obliterated, especially in the first 1-2 days after surgery, and this appears closely related to the use of high-dose opioids. Sleep-disordered breathing is common in postoperative patients, and tools such as the Sleep Apnea Clinical Score or the STOP-BANG (Snoring, Tiredness, Observed apnea, and high blood Pressure - Body mass index, Age, Neck circumference, and Gender) questionnaires have been utilized to predict the possibility of obstructive sleep apnea (OSA) and postoperative respiratory complications. Protocols to evaluate patients that determine the need and process for positive-airway-pressure treatment in the hospital patient with OSA are being developed. An obstructive apnea systematic intervention strategy protocol to deal with patients with suspected OSA can help guide diagnostic and therapeutic decision making. Hospitals that are proactive in the development of protocols for identification and management of patients with sleep-disordered breathing are likely to be rewarded with reduced complications and costs, and the issue is sure to be incorporated in future pay-for-performance evaluations.

Tuberculosis which mainly involves the lungs, can also cause infection in almost all other organs and tissues in the body. One of the most common forms of extrapulmonary tuberculosis is tuberculous lymphadenitis. In this study, tuberculous lymphadenitis cases reported from Turkey in national and international journals in the last 12 years, were reviewed systematically with pooled-analysis method. Related articles were retrieved by search of three national (Ulakbim Turkish Medical literature databases, http://www.turkishmedline.com, http://medline.pleksus.com.tr) and two international databases [PubMed and Science Citation Index (SCI)]. Between the years 1997-2009, tuberculous lymphadenitis cases have been published in a total of 44 articles (13 international, 31 national data base). These articles included a total of 694 tuberculous lymphadenitis cases (62.4% women, 37.6% men; mean age 37.5 years). The distribution of the lymph nodes involved was determined in 528 cases and the most commonly involved areas were cervical (61.4%), mediastinal (20.5%) and axillary (6.4%) areas. The most common complaints of patients were fever (15.8%), weight loss (14.5%), malaise-fatigue (13.1%) and sweating (12.4%). Tuberculous lymphadenitis was identified in 10.6% (51/479) of the cases by direct microscopical examination, in 15.9% (65/408) by culture and in 648 cases from whom biopsies were taken, by histopathological examination. Tuberculin skin test positivity was detected in 78.9% (377/478) cases. History of contact with active tuberculosis patients was determined in 24.2% (88/364) of the patients. Coexisting lung tuberculosis was detected in 7.8% (54/694) of the cases. The total number of cases that had died was four; two cases due to malignancy, one due to sepsis and one due to central nervous system tuberculosis that have developed four years following the diagnosis of tuberculous lymphadenitis. Since microbiological diagnosis is difficult in tuberculous lymphadenitis and not available in all centers, evaluation of the patients' history and clinical findings are of great importance. This pooled analysis which enabled the evaluation of a large number of tuberculous lymphadenitis cases, indicated that in countries where tuberculosis is widespread, careful evaluation of clinical findings and a good microbiological and histopathological investigation will provide valuable support for diagnosis and treatment of tuberculous lymphadenitis.

Meningococcal infections may develop as episodic or endemic cases particularly among children attending day-care centers, boarding schools or among military personnel. Bivalent (A/C) meningococcal vaccine is applied to all new military stuff since 1993 in Turkey. In this report two cases of meningococcemia and meningitis, developed in two soldiers vaccinated with meningococcal vaccine, were presented. The first case was a 21 years old male patient who was admitted to the emergency service with the complaints of high fever, headache, fatigue and vomiting. He was conscious, cooperative and oriented with normal neurological findings. Maculopapular exanthems were detected at the lower extremities. The patient was hospitalized with the initial diagnosis of sepsis or meningococcemia and empirical treatment was initiated with ceftriaxone and dexamethasone. Cerebrospinal fluid (CSF) examination yielded 10 cells/mm3 (lymphocytes) with normal CSF biochemical parameters. A few hours later skin rashes spread over the body rapidly, the symptoms got worse, confusion, disorientation and disorientation developed, and the patient died due to cardiac and respiratory arrest at the seventh hour of his admission. The second case was also a 21 years old male patient who was admitted to the hospital with the complaints of fever, headache, painful urination, confusion and agitation. He was initially diagnosed as acute bacterial meningitis due to clinical (stiff neck, positive Kernig and Brudzinsky signs) and CSF (8000 cells/mm3; 80% polymorphonuclear leukocytes, increased protein and decreased glucose levels) findings. Empirical antibiotic therapy with ceftriaxone was initiated and continued for 14 days. The patient was discharged with complete cure and no complication was detected in his follow-up visit after two months. The first case had an history of vaccination with bivalent (A/C) meningococcal vaccine three months ago and the second case had been vaccinated one month ago. The bacteria isolated from the blood culture of the first case and the CFS culture of the second case, were identified as Neisseria meningitidis by conventional and API NH system (BioMerieux, France). The isolates were serogrouped as W135 by slide agglutination method (Difco, USA), and both were found to be susceptible to penicillin and ceftriaxone. As far as the last decade's literature and these two cases were considered, it might be concluded that N.meningitidis W135 strains which were not included in the current bivalent meningococcal vaccine, gained endemic potential in Turkey. Since N.meningitidis W135 strains may lead to serious diseases, vaccination of the risk population with the conjugate tetravalent meningococcal vaccine (A/C/Y/W135) should be taken into consideration in Turkey.

Intravascular large B cell lymphoma (IVLBCL) is a rare type of extranodal large B cell lymphoma in the lumina of small vessels. Low high-density lipoprotein cholesterol (HDL-C) is associated with sepsis, malignancy, and death. Recent evidence suggests an inverse relationship between HDL-C and non-Hodgkin lymphoma. We report the case of a 71-year-old female who presented with decreasing HDL-C for years prior to diagnosis of IVLBCL. The patient developed nonspecific symptoms, including dizziness, gait instability, fatigue, tinnitus, and weight loss. Although malignancy was high on the differential, no diagnosis was made antemortem. The diagnosis of disseminated intravascular large B cell lymphoma was made postmortem in multiple organ systems. The presentation of IVLBCL is nonspecific and misleading. To our knowledge this is the second known case report of low HDL-C preceding diagnosis of IVLBCL, but the first case documenting low HDL-C years prior to diagnosis.
