Cardiopulmonary exercise testing in long covid shows the presence of dysautonomia or chronotropic incompetence independent of subjective exercise intolerance and fatigue.

BACKGROUND: After COVID-19 infection, 10-20% of patients suffer from varying symptoms lasting more than 12 weeks (Long COVID, LC). Exercise intolerance and fatigue are common in LC. The aim was to measure the maximal exercise capacity of the LC patients with these symptoms and to analyze whether this capacity was related to heart rate (HR) responses at rest and during exercise and recovery, to find out possible sympathetic overactivity, dysautonomia or chronotropic incompetence. METHODS: Cardiopulmonary exercise test was conducted on 101 LC patients, who were admitted to exercise testing. The majority of them (86%) had been treated at home during their acute COVID-19 infection. Peak oxygen uptake (VO2peak), maximal power during the last 4 min of exercise (Wlast4), HRs, and other exercise test variables were compared between those with or without subjective exercise intolerance, fatigue, or both. RESULTS: The measurements were performed in mean 12.7 months (SD 5.75) after COVID-19 infection in patients with exercise intolerance (group EI, 19 patients), fatigue (group F, 31 patients), their combination (group EI + F, 37 patients), or neither (group N, 14 patients). Exercise capacity was, in the mean, normal in all symptom groups and did not significantly differ among them. HRs were higher in group EI + F than in group N at maximum exercise (169/min vs. 158/min, p = 0.034) and 10 min after exercise (104/min vs. 87/min, p = 0.028). Independent of symptoms, 12 patients filled the criteria of dysautonomia associated with slightly decreased Wlast4 (73% vs. 91% of sex, age, height, and weight-based reference values p = 0.017) and 13 filled the criteria of chronotropic incompetence with the lowest Wlast4 (63% vs. 93%, p < 0.001), VO2peak (70% vs. 94%, p < 0.001), the lowest increase of systolic blood pressure (50 mmHg vs. 67 mmHg, p = 0.001), and the greatest prevalence of slight ECG-findings (p = 0.017) compared to patients without these features. The highest prevalence of chronotropic incompetence was seen in the group N (p = 0.022). CONCLUSIONS: This study on LC patients with different symptoms showed that cardiopulmonary exercise capacity was in mean normal, with increased sympathetic activity in most patients. However, we identified subgroups with dysautonomia or chronotropic incompetence with a lowered exercise capacity as measured by Wlast4 or VO2peak. Subjective exercise intolerance and fatigue poorly foresaw the level of exercise capacity. The results could be used to plan the rehabilitation from LC and for selection of the patients suitable for it.

Incidence of sexually transmitted infections is lower among kidney transplant recipients compared to the general population-A nationwide cohort study.

AIM: The burden of sexually transmitted infections (STI) among solid-organ transplant recipients is currently unknown. We studied the risk of STIs among kidney transplant recipients compared with the general population in a nationwide cohort. METHODS: Between 2002 and 2019, all microbiological findings of Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum (syphilis), and human immunodeficiency virus among kidney transplant recipients <65 years and transplanted between 1995 and 2017 in our country were captured from statutory national registries. Data from the general population of Finland, population 5.5 million, were used for comparisons. Incidence of STIs and age and sex-adjusted standardized incidence ratios (SIR) were calculated. RESULTS: Altogether 3612 transplantations, with a total follow-up of 27 069 person-years were included. A total of 30 STIs microbiological findings of STI were confirmed in 25 patients: C. trachomatis (N = 27), N. gonorrhoeae (N = 2), and syphilis (N = 1). No hospitalizations associated with STIs were detected. The risk of STI after kidney transplantation was significantly lower compared to the general population (SIR, 0.57, 95% CI 0.39-0.80). The lower risk of STIs was more pronounced in female patients (SIR 0.40, 95% CI 0.20-0.74), whereas in male patients the difference was statistically not significant (SIR 0.69, 95% CI 0.44-1.04). Of the confirmed STI cases, 30% were detected in patients who received their transplants during adolescence. CONCLUSIONS: Within the Finnish kidney transplant population, the age and sex-adjusted incidence of sexually transmitted infections is not higher compared to the general population. Highest frequency of infections was seen among patients transplanted during adolescence.

Oral Doxycycline Compared to Intravenous Ceftriaxone in the Treatment of Lyme Neuroborreliosis: A Multicenter, Equivalence, Randomized, Open-label Trial.

BACKGROUND: Lyme neuroborreliosis (LNB) is often treated with intravenous ceftriaxone even if doxycycline is suggested to be noninferior to ceftriaxone. We evaluated the efficacy of oral doxycycline in comparison to ceftriaxone in the treatment of LNB. METHODS: Patients with neurological symptoms suggestive of LNB without other obvious reasons were recruited. The inclusion criteria were (1) production of Borrelia burgdorferi-specific antibodies in cerebrospinal fluid (CSF) or serum; (2) B. burgdorferi DNA in the CSF; or (3) an erythema migrans during the past 3 months. Participants were randomized in a 1:1 ratio to receive either oral doxycycline 100 mg twice daily for 4 weeks, or intravenous ceftriaxone 2 g daily for 3 weeks. The participants described their subjective condition with a visual analogue scale (VAS) from 0 to 10 (0 = normal; 10 = worst) before the treatment, and 4 and 12 months after the treatment. The primary outcome was the change in the VAS score at 12 months. RESULTS: Between 14 September 2012 and 28 December 2017, 210 adults with suspected LNB were assigned to receive doxycycline (n = 104) or ceftriaxone (n = 106). The per-protocol analysis comprised 82 patients with doxycycline and 84 patients with ceftriaxone. The mean change in the VAS score was -3.9 in the doxycycline group and -3.8 in the ceftriaxone group (mean difference, 0.17 [95% confidence interval, -.59 to .92], which is within the prespecified equivalence margins of -1 to 1 units). Participants in both groups improved equally. CONCLUSIONS: Oral doxycycline is equally effective as intravenous ceftriaxone in the treatment of LNB.

Epidemiology of laboratory-confirmed influenza among kidney transplant recipients compared to the general population-A nationwide cohort study.

Seasonal influenza causes morbidity and mortality after organ transplantation. We quantified the detection of laboratory-confirmed influenza among kidney transplant recipients compared to the general population in a nationwide cohort. All laboratory-confirmed cases of influenza and hospitalizations due to influenza among all kidney transplant recipients in our country between 1995 and 2017 were captured with database linkage from statutory national registries. Data from the general population of Finland, population 5.5 million, were used for comparisons. Annual incidences of influenza and hospitalizations due to influenza, and standardized incidence ratios (SIR) were calculated. Altogether 3904 kidney transplant recipients with a total follow-up of 37 175 patient-years were included. Incidence of laboratory-confirmed influenza was 9.0 per 1000 patient years in 2003-2019, and 18.0 per 1000 patient years during 2015-2019. The risk of laboratory-confirmed influenza was significantly higher among kidney transplant recipients compared to the general population (SIR 5.1, 95% CI 4.5-5.7). SIR for hospitalization due to influenza was 4.4 (95% CI 3.4-4.7). Mortality of the hospitalized patients was 9%, and 5% of the patients with laboratory-confirmed influenza. Detection of laboratory-confirmed influenza is increased fivefold and risk of hospitalization due to influenza more than fourfold among kidney transplant recipients compared to the general population.

Prognosis of patients with post-Covid-19 condition: Prospective cohort cluster analysis at one year.

OBJECTIVE: We aimed to identify clinically relevant clusters among patients with post-Covid-19 condition (PCC) and assess prognosis overall and within clusters. METHODS: Prospective cohort study of patients with PCC attending a rehabilitation clinic. We monitored patient reported outcome measures (PROMs): EuroHIS quality of life and symptoms. Unsupervised hierarchical cluster analyses were performed to identify clusters of patients with different quantity of symptoms, and symptoms presenting together. Preliminary findings on symptom prevalence and quality of life at 12 months are reported. RESULTS: Among 409 patients, 70.4% were women, with an average baseline of 20.3 (SD 6.8) symptoms. Three clusters emerged based on symptom quantity, labelled by the average number of symptoms at baseline: Cluster-11 (17% of all patients), Cluster-17 (35%), and Cluster-25 (48%). Multinomial logistic regression showed female sex, multiple comorbidities predicting more symptoms. Four symptom-based clusters were defined: fatigue and cognitive complaints; pain, trouble sleeping, palpitations and other symptoms; gastrointestinal symptoms; and emotion-related symptoms. Linear regression models showed that female sex, multiple comorbidities, anxiety, use of antidepressants, BMI and smoking were among the determinants of symptom clusters. In 12-month follow-up, symptom count decreased, and quality of life improved across all clusters, with 9% having good quality of life at baseline and 33% at 12 months. CONCLUSION: Four patient clusters based on symptoms were identified in the PCC cohort. Prognosis was favorable across all clusters, with symptom reduction and improved quality of life observed. Female sex, comorbidities, BMI, and mental-health related variables predicted higher symptom burden, suggesting multifactorial origins of PCC.

Maturing neutrophils of lower density associate with thrombocytopenia in Puumala orthohantavirus-caused hemorrhagic fever with renal syndrome.

Puumala orthohantavirus-caused hemorrhagic fever with renal syndrome (PUUV-HFRS) is characterized by strong neutrophil activation. Neutrophils are the most abundant immune cell type in the circulation and are specially equipped to rapidly respond to infections. They are more heterogenous than previously appreciated, with specific neutrophil subsets recently implicated in inflammation and immunosuppression. Furthermore, neutrophils can be divided based on their density to either low-density granulocytes (LDGs) or "normal density" polymorphonuclear cell (PMN) fractions. In the current study we aimed to identify and characterize the different neutrophil subsets in the circulation of PUUV-HFRS patients. PMNs exhibited an activation of antiviral pathways, while circulating LDGs were increased in frequency following acute PUUV-HFRS. Furthermore, cell surface marker expression analysis revealed that PUUV-associated LDGs are primarily immature and most likely reflect an increased neutrophil production from the bone marrow. Interestingly, both the frequency of LDGs and the presence of a "left shift" in blood associated with the extent of thrombocytopenia, one of the hallmarks of severe HFRS, suggesting that maturing neutrophils could play a role in disease pathogenesis. These results imply that elevated circulating LDGs might be a general finding in acute viral infections. However, in contrast to the COVID-19 associated LDGs described previously, the secretome of PUUV LDGs did not show significant immunosuppressive ability, which suggests inherent biological differences in the LDG responses that can be dependent on the causative virus or differing infection kinetics.

Severe infections in peritoneal dialysis and home hemodialysis patients: An inception cohort study.

OBJECTIVES: Infections are the most common non-cardiovascular cause of death among dialysis patients. Earlier studies have shown similar or higher risk of infectious complications in peritoneal dialysis (PD) compared to hemodialysis (HD) patients, but comparisons to home HD patients have been rare. We investigated the risk of severe infections after start of continuous ambulatory PD (CAPD) and automated PD (APD) as compared to home HD. METHODS: All adult patients (n = 536), who were on home dialysis at day 90 from starting kidney replacement therapy (KRT) between 2004 and 2017 in Helsinki healthcare district, were included. We defined severe infection as an infection with C-reactive protein of 100 mg/l or higher. Cumulative incidence of first severe infection was assessed considering death as a competing risk. Hazard ratios were estimated using Cox regression with propensity score adjustment. RESULTS: The risk of getting a severe infection during the first year of dialysis was 35% for CAPD, 25% for APD and 11% for home HD patients. During five years of follow-up, the hazard ratio of severe infection was 2.8 [95% CI 1.6-4.8] for CAPD and 2.2 [95% CI 1.4-3.5] for APD in comparison to home HD. Incidence rate of severe infections per 1000 patient-years was 537 for CAPD, 371 for APD, and 197 for home HD patients. When excluding peritonitis, the incidence rate was not higher among PD than home HD patients. CONCLUSIONS: CAPD and APD patients had higher risk of severe infections than home HD patients. This was explained by PD-associated peritonitis.

Prognosis of patients with long COVID symptoms: a protocol for a longitudinal cohort study at a primary care referred outpatient clinic in Helsinki, Finland.

INTRODUCTION: After COVID-19, many continue to experience persistent debilitating symptoms, that is, long COVID. Its most prevalent symptoms are chest pain, difficulties with breathing, painful muscles, ageusia or anosmia, tingling extremities and general tiredness. This paper describes the protocol of the Long COVID Cohort Study to assess the prognosis and prognostic determinants of patients with long COVID by implementing patient-reported outcome measures (PROMs), patient-reported experience measures (PREMs) and clinical examinations during a 1-year follow-up. METHODS AND ANALYSIS: This is a prospective, single-site cohort study consisting of administering questionnaires and clinical examinations to adult patients referred to the Clinic for Long-Term Effects of COVID-19 at Helsinki University Hospital (Hospital district of Helsinki and Uusimaa). The referrals are from all healthcare units within HUS and other hospital districts during years 2021-2023. All admitted patients have had laboratory-confirmed COVID-19. The targeted study sample size is 500 participants. The questionnaires are administered at 0, 3, 6 and 12 months. The main outcome variables are the changes in self-reported functional abilities and quality of life. In addition, we will evaluate functional abilities at baseline using neurocognitive evaluation, a 6MWT and a measurement of hand grip strength. The Long COVID Cohort Study will form a quality register for the clinic and characterise the first systematic collection of PROMs, PREMs, questionnaire and clinical examinations related to long COVID in Finland. The Study belongs to a study consortium Long COVID-HORIZON-HLTH-2021-DISEASE-04 that aims to reveal the biomechanisms of long COVID. ETHICS AND DISSEMINATION: This study has been approved by the Helsinki University Hospital research ethics committee board, ID HUS/1493/2021 on 6 March 2021. All study participants sign written informed consent for participation. The study findings will be reported for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05699512; Pre-results.

[Gut bacteria and antimicrobial resistance--what to worry about]. / Suolistoperäiset moniresistentit bakteerit kliinikon huolenaiheena.

Gram negative and anaerobic bacteria from gut microbiota are important pathogens both in community-acquired and hospital infections. Escherichia coli is the the most common cause of adult bacteraemias in Finland. Antimicrobial resistance in these bacteria is a threatening phenomenon. Enterobacteriacae producing extended spectrum beta-lactamase (ESBL) have spead worldwide. The use of antimicrobial agents shifts the balance in gut microbiota and induces and selects bacterial resistance. When resistant bacteria cause infections, empiric antimicrobial therapy may not cover them, which may increase lenght of hospital stay, costs and mortality due to infections.

Borrelia burgdorferi specific serum and cerebrospinal fluid antibodies in Lyme neuroborreliosis.

We used definite Lyme neuroborreliosis (LNB) adult patient acute and convalescent phase serum (n = 63 and 61, respectively) and cerebrospinal fluid (CSF; acute n = 63, 3 weeks timepoint n = 41) samples to characterize Borrelia burgdorferi specific antibody responses in patient subgroups categorized by demographics, infection manifestation and phase, infecting B. burgdorferi genospecies, received antibiotic treatments, and treatment outcome. B. burgdorferi antibodies were analyzed using 4 different assays incorporating a large array of antigens. We observed that B. burgdorferi specific serum antibodies show a universal, antigen independent declining trend after antibiotic treatment of LNB at 1 year. Antibodies declined similarly among women and men over time, and the decline was independent of patient age. The antibody responses were independent of the predominant LNB manifestation, treatment received by the patient, infecting B. burgdorferi genospecies, or the subjective improvement experienced by the patients. Finally, the antibody specificities in CSF reflected the specificities observed in serum samples.

Consumption of healthcare services and antibiotics in patients with presumed disseminated Lyme borreliosis before and after evaluation of an infectious disease specialist.

Our objective was to study the consumption of healthcare services and antibiotics in patients with suspicion of disseminated Lyme borreliosis (LB) before and after consultation of an infectious disease specialist. We evaluated retrospectively all presumed disseminated LB patients (n = 256) with a referral to the Department of Infectious Diseases (DID) in Helsinki University Hospital in 2013. Medical records from all healthcare providers in the area were reviewed and the number of physician contacts because of symptoms leading to LB suspicion and antimicrobial purchases were calculated 1 year before and after consultation or treatment at the DID. Patients were divided into three groups according to certainty of LB: unlikely, possible or probable/definite LB. The number of healthcare contacts 1 year before referral was higher among 121 patients with unlikely LB (6; interquartile range [IQR] 3-10), than 65 possible (4; IQR 2.5-7; p = 0.018) or 66 probable/definite LB patients (4; IQR 2.8-7; p = 0.010). The median number of contacts to healthcare during one year after consultation or treatment was 3 (IQR 0.5-7), 1 (IQR 0-3) and 0.5 (IQR 0-2.3), respectively, with a statistically significant difference between the groups (p<0.001). Antibiotics were purchased by 151 (60%) patients one year before referral and by 127 (50%) patients year after consultation or treatment at DID without statistically significant difference between groups with different LB certainty. These antibiotic purchases do not include the treatments prescribed by infectious disease specialists. In the case of 27 patients, an antimicrobial treatment was recommended in the consultation reply. In conclusion, patients with unlikely LB used more healthcare services than patients with possible or probable/definite LB. Antimicrobial consumption was similar between groups of different LB certainty.

Benchmarking antibiotic use in Finnish acute care hospitals using patient case-mix adjustment.

OBJECTIVES: It is difficult to draw conclusions about the prudence of antibiotic use in different hospitals by directly comparing usage figures. We present a patient case-mix adjustment model of antibiotic use to rank hospitals while taking patient characteristics into account. PATIENTS AND METHODS: Data on antibiotic use were collected during the national healthcare-associated infection (HAI) prevalence survey in 2005 in Finland in all 5 tertiary care, all 15 secondary care and 10 (25% of 40) other acute care hospitals. The use of antibiotics was measured using use-days/100 patient-days during a 7day period and the prevalence of patients receiving at least two antimicrobials during the study day. Case-mix-adjusted antibiotic use was calculated by using multivariate models and an indirect standardization method. Parameters in the model included age, sex, severity of underlying diseases, intensive care, haematology, preceding surgery, respirator, central venous and urinary catheters, community-associated infection, HAI and contact isolation due to methicillin-resistant Staphylococcus aureus. RESULTS: The ranking order changed one position in 12 (40%) hospitals and more than two positions in 13 (43%) hospitals when the case-mix-adjusted figures were compared with those observed. In 24 hospitals (80%), the antibiotic use density observed was lower than expected by the case-mix-adjusted use density. CONCLUSIONS: The patient case-mix adjustment of antibiotic use ranked the hospitals differently from the ranking according to observed use, and may be a useful tool for benchmarking hospital antibiotic use. However, the best set of easily and widely available parameters that would describe both patient material and hospital activities remains to be determined.

Point prevalence survey is useful for introducing effective surveillance of healthcare-associated infections.

BACKGROUND: In Finland, the surveillance of healthcare-associated infections (HAI) became obligatory by the renewed Communicable Diseases Act on the 1st March 2017. AIM: To introduce HAI surveillance protocol (HALT-2 by ECDC) in primary care hospitals in the largest hospital district in Finland, and to measure the burden of HAIs and antimicrobial use patterns for improvement. METHODS: Two identical point prevalence surveys (PPS) were organized in autumn 2015 and in spring 2017. The infection control persons (ICP) in the hospitals were inducted to the HAI definitions and the study protocol to collect the data with questionnaires on the study days. The data were checked and analyzed by the areal infection control unit. The hospitals were provided feedback of the results and HAI prevention methods. FINDINGS: In 2015, 2218 patients from 22 hospitals and in 2017, 2343 patients from 25 hospitals were studied. The prevalence of HAI was 11% in both surveys (ranges per hospital 4-24% and 4-31%, respectively). Of all HAIs, 37% originated from referring hospitals. Respiratory tract, urinary tract and skin were the most frequent sites of infection. One fourth of all patients received at least one systemic antimicrobial. The process showed that recognition of HAIs may be difficult for non-experienced ICPs. CONCLUSIONS: The HALT-2 protocol proved useful in introducing HAI surveillance and prevention in primary care hospitals with active patient transfer from other hospitals and relatively high prevalence of HAI and antimicrobial use. For annually repeated surveys, slightly shorter electronic questionnaires are essential.

Lyme neuroborreliosis-associated cerebrovascular events in the Finnish endemic area.

OBJECTIVES: Neuroborreliosis is a rare cause of cerebral vasculitis and stroke. The incidence of Lyme borreliosis in Finland has been increasing in the last 20 years, so we expect that Lyme neuroborreliosis-associated vasculitis can be a more common cause of stroke in the future. MATERIALS & METHODS: We have retrospectively identified all adult patients (>16 years old) diagnosed with borreliosis (A69.2 Lyme borreliosis), transient ischemic attack (TIA, G45), and ischemic stroke (I63) at Helsinki University Hospital during 1.1.2014-31.10.2019 at our neurological emergency department. Medical data and follow-up data were retrospectively collected from medical records. Neuroborreliosis was diagnosed according to the European Federation of Neurological Societies guidelines. RESULTS: We have identified 10 cases of neuroborreliosis-associated stroke or TIA and/or vasculitis. Vasculitis as a manifestation of borreliosis was diagnosed in six patients of 1454 (0.4%) and stroke or TIA in nine (0.6%) of all borreliosis patients at Helsinki University Hospital. Clinical outcomes for all our patients were good with a modified Rankin scale (mRS) 0-2. CONCLUSIONS: Lyme neuroborreliosis-associated vasculopathy and cerebrovascular events still remain rare but should be considered especially in Lyme borreliosis endemic areas. Prognosis is good with appropriate antibiotic treatment, but additional immunosupressive treatment is sometimes needed.

Suspicion of Lyme borreliosis in patients referred to an infectious diseases clinic: what did the patients really have?

OBJECTIVE: To evaluate the conditions behind the symptoms in patients with suspected Lyme borreliosis (LB) who were referred to an infectious diseases clinic. METHODS: In this retrospective, population-based study, we collected data from the medical records of all patients referred for infectious disease consultations in 2013 due to presumed LB from a population of 1.58 million. The patients were classified according to the certainty of LB on the basis of their symptoms, signs and laboratory results. Data on the outcomes and subsequent alternative diagnoses during the 4-year follow-up period were reviewed from all of the available patient records from public, private and occupational healthcare providers. RESULTS: A total of 256 patients (16/100 000) were referred as a result of suspicion of LB; 30 (12%) of 256 were classified with definite, 36 (14%) with probable and 65 (25%) with possible LB. LB was unlikely in 121 (47%) patients. A novel diagnosis was discovered in the background symptoms in 73 (29%) of patients. Previously diagnosed comorbidities caused at least some of the symptoms in 48 (19%) patients. Other explanations for symptoms were found in 81 (67%) of 121 of unlikely and 22 (34%) of 65 of possible LB patients. The spectrum of conditions behind the symptoms was quite broad and most often were musculoskeletal, neurological, psychological or functional disorders. CONCLUSIONS: LB was unlikely in half of the patients with presumed LB. In most cases the patients had other conditions that explained their symptoms.

C6 peptide enzyme immunoassay in Lyme borreliosis serology.

The cut-off values used in C6 peptide-based enzyme immunoassay (EIA), a widely used test in Lyme borreliosis (LB) serology, have not been thoroughly analysed. The objective of the study was to examine the performance of the C6 EIA, and to determine optimal cut-off values for the test. The analysed data contained results of 1368 serum samples. C6 EIA index values were compared statistically with the immunoblot (IB) test results. The identified cut-off values were further tested in a well-defined LB patient cohort. Cut-off value 1.6 appeared to be optimal when C6 EIA was used as a stand-alone test. When using C6 EIA as the first-tier test, the optimal cut-off values were 0.9 and 2.4 for negative and positive results. When C6 EIA was used as a second-tier test, samples yielding C6 index values ≥3.0 could be considered positive. The identified cut-off values had also a high sensitivity to identify seropositivity among definite LB patients. The identified cut-off values refine the role of C6 EIA in LB serology. Importantly, the use of C6 EIA leads to a reduction in the number of samples that need to be analysed using an IB, thus also reducing the costs. Two alternative workflows for LB serology including the C6 EIA are suggested.

Human cases of methicillin-resistant Staphylococcus aureus CC398, Finland.

Nationwide surveillance identified 10 human isolates of methicillin-resistant Staphylococcus aureus clonal complex (CC) 398. Further typing in comparison with animal isolates identified 4 clusters: 1 related to a horse epidemic and 3 to persons who had no direct contact with animals or each other. These findings may indicate unrecognized community transmission.

[Rabies]. / Vesikauhu.

Rabies is a mammalian zoonosis caused by a virus belonging to the family of rhabdoviruses. In Finland, the risk of rabies is associated with imported animals and traveling. We describe the second case of human rabies diagnosed in Finland. Strong hydrophobia was present in the initial phase of the disease. The patient had encephalomyelitis, and he died 11 days after the onset of symptoms. Diagnosis was confirmed by RT-PCR using Saliva. Rabies infection leads invariably to death, but can. be prevented after the exposure with vaccine and immunoglobulin therapy.

Community-associated methicillin-resistant Staphylococcus aureus isolated in Finland in 2004 to 2006.

A nationwide population-based study on community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in Finland during 2004 to 2006 showed that both incidence (1.9/100,000 population) and strain variation increased in comparison to years 1997 to 1999. There were 7 community-associated epidemic and 25 sporadic MRSA strain types. Half of these had Panton-Valentine leukocidin genes.

Focal atrophy of the unilateral masticatory muscles caused by pure trigeminal motor neuropathy: case report.

Patients with unknown clinical or radiological asymmetry in the face structures combined with atrophy and weakness of the masticatory muscles should be comprehensively examined clinically and with MRI, neurophysiological measurements, and serologically. Malignant lesions or benign idiopathic unilateral trigeminal motor neuropathy should be considered as an etiological explanation for the asymmetry.
