Eight years experience from a skeletal dysplasia referral center in a tertiary hospital in Southern India: A model for the diagnosis and treatment of rare diseases in a developing country.

We report on a series of 514 consecutive diagnoses of skeletal dysplasia made over an 8-year period at a tertiary hospital in Kerala, India. The most common diagnostic groups were dysostosis multiplex group (n = 73) followed by FGFR3 (n = 49) and osteogenesis imperfecta and decreased bone density group (n = 41). Molecular confirmation was obtained in 109 cases. Clinical and radiographic evaluation was obtained in close diagnostic collaboration with expert groups abroad through Internet communication for difficult cases. This has allowed for targeted biochemical and molecular studies leading to the correct identification of rare or novel conditions, which has not only helped affected families by allowing for improved genetic counseling and prenatal diagnosis but also resulted in several scientific contributions. We conclude that (1) the spectrum of genetic bone disease in Kerala, India, is similar to that of other parts of the world, but recessive entities may be more frequent because of widespread consanguinity; (2) prenatal detection of skeletal dysplasias remains relatively rare because of limited access to expert prenatal ultrasound facilities; (3) because of the low accessibility to molecular tests, precise clinical-radiographic phenotyping remains the mainstay of diagnosis and counseling and of gatekeeping to efficient laboratory testing; (4) good phenotyping allows, a significant contribution to the recognition and characterization of novel entities. We suggest that the tight collaboration between a local reference center with dedicated personnel and expert diagnostic networks may be a proficient model to bring current diagnostics to developing countries. © 2014 Wiley Periodicals, Inc.

Panobacumab adjunctive immuno-therapy for Pseudomonas aeruginosa hospital-acquired pneumonia versus a cohort group

Objectives: To assess the efficacy of Panobacumab, a fully human IgM monoclonal antibody against P. aeruginosa serotype O11, by comparing a phase IIa trial with a standard care cohort trial both in hospital acquired pneumonia (HAP) caused by P. aeruginosa O11. Methods: Demographics, outcome and survival of HAP including Ventilator Associated Pneumonia (VAP) in patients either treated with standard antimicrobial therapy in a retrospective cohort trial (CT) or with adjunctive Panobacumab therapy during an open phase IIa trial were compared. Both trials applied the same inclusion exclusion criteria and the same trial period of 30 days. Results: 17 patients with VAP/HAP (14 / 3) caused by P. aeruginosa O11 were enrolled in a phase IIa trial (ITT population) and treated with Panobacumab, 13 of them received the full treatment course of 3 infusions (PP population, 12 VAP, 1 HAP) and 4 patients received only one infusion. In the cohort trial 14 patients (VAP/HAP: 12 / 2) treated with standard antibiotic therapy were included. The mean age and weight were 65.8 y (years) (SD 17.2) and 78.0 kg (SD 22.1) in the PP, 67.8 y (SD 15.4) and 77.1 kg (SD 20.2) in the ITT population and 51.8 y (SD 22.3) and 67.1 kg (SD 13.0) in the CT. At the time of suspicion of pneumonia a mean APACHE II and CPIS of 19.4 (13 - 33) and 8.7 (7 - 11) in the PP, 18.9 (13-33) and 8.5 (7 -11) in the ITT and 14.5 (2 - 24) and 7.5 (3 -12) in the CT population were observed. Tracheostomy was present in 53.8% and 52.9% in the PP and ITT populations and 38.4% in the CT. The pneumonia was polymicrobial in 69.2%, 70.6% and 85.7% in the PP, ITT and CT respectively. Stay at ICU and hospital before diagnosis of pneumonia were similar in the 3 groups. All 13 patients that received 3 doses of Panobacumab achieved resolution of pneumonia with only two relapsing during the study. Hence 85% achieved resolution and 15% recurrence at day 30. In the ITT group 64.7% of the pneumonia resolved 11.8% recurred and 23.5% continued while in the CT 57% resolved, 7% recurred and 34% continued. Resolution of pneumonia occurred markedly earlier in the Panobacumab trial (8.9 days, SD: 3.3) than in the cohort trial (15.3 days, SD: 9.5). The expected mortality derived from APACHE II score was 31% and 32% in the PP and ITT population and 22% in the cohort group. All patients who received 3 doses of Panobacumab survived, 18% died in the ITT group while in the CT 21% mortality matched the predicted mortality. Conclusions: Treatment of VAP/HAP caused by P. aeruginosa O11 with 3 doses of Panobacumab resulted in 100% survival, with highest pneumonia resolution (85%), and in a shorter time when compared with patients under standard therapy. The results indicate that Panobacumab may be effective in such life-threatening indication and warrants larger controlled trials.

Cerebral and extracerebral cholesterol metabolism and CSF markers of Alzheimer's disease.

The disturbances of the cholesterol synthesis and metabolism described in Alzheimer's disease (AD) may be both a consequence of the neurodegenerative process and a contributor to the pathogenesis. These putative relationships and their underlying mechanisms are not well understood. The aim of this study was to evaluate the relationship between the cerebral and extracerebral cholesterol synthesis and metabolism, and the AD pathology as reflected by CSF markers in humans. We evaluated the relationships between the plasma and the cerebrospinal fluid (CSF) concentrations of cholesterol, the cholesterol precursors lanosterol, lathosterol and desmosterol, and the cholesterol elimination products 24S-hydroxycholesterol and 27-hydroxycholesterol, and the CSF markers for AD pathology Aβ1-42 and p-tau181 in 86 subjects with normal cognition and in 107 AD patients. CSF desmosterol, cholesterol and 24S-hydroxycholesterol in the AD group, and CSF 24S-hydroxycholesterol in the control group correlated with the p-tau181 levels. Neither CSF nor plasma concentrations of the included compounds correlated with the CSF Aβ1-42 levels. In multivariate regression tests including age, gender, albumin ratio, number of the APOEε4 alleles, and diagnosis, p-tau181 levels independently predicted the CSF desmosterol, cholesterol and 24S-hydroxycholesterol concentrations. The associations remained significant for CSF cholesterol and 24S-hydroxycholesterol when analyses were separately performed in the AD group. The results suggest that alterations of CNS cholesterol de novo genesis and metabolism are related to neurodegeneration and in particular to the cerebral accumulation of phosphorylated tau.

Intratympanic application of an antiviral agent for the treatment of Ménière's disease.

It has been suggested that Ménière's disease is part of a polyganglionitis in which symptoms result from the reactivation of neurotropic virus within the internal auditory canal, and that intratympanic applications of an antiviral agent might be an efficient therapy. In 2002, we performed a pilot study ending with encouraging results. Control of vertigo was achieved in 80% of the 17 patients included. We present here a prospective, double-blind study, with a 2-year follow-up, in 29 patients referred by ENT practitioners for a surgical treatment after failure of a medical therapy. The participation in the study was offered to patients prior to surgery. A solution of ganciclovir 50 mg/ml or of NaCl 9% was delivered for 10 consecutive days via a microwick inserted into the tympanic membrane in the direction of the round window or through a ventilation tube. One patient was withdrawn from the study immediately after the end of the injections. He could not complete the follow-up period, because of persisting vertigo. As he had received the placebo, he was then treated with the solution of ganciclovir. Symptoms persisted and he underwent a vestibular neurectomy. Among the remaining 28 patients, surgery could be postponed in 22 (81%). Surgery remained necessary to control vertigo in 3 patients from the group that received the antiviral agent, and in 3 from the control group. Using an analogical scale, patients of both groups indicated a similar improvement of their health immediately after the intratympanic injections. The scores obtained with a 36-item short-form health survey quality of life questionnaire and the Dizziness Handicap Inventory were also similar for both groups. In conclusion, most patients were improved after the intratympanic injections, but there was no obvious difference between the treated and control groups. The benefit might be due to the middle ear ventilation or reflect an improvement in the patients' emotional state.

Follow-up care amongst long-term childhood cancer survivors: a report from the Swiss Childhood Cancer Survivor Study.

In the Swiss Childhood Cancer Survivor Study, we aimed to assess the proportion of long-term survivors attending follow-up care, to characterise attendees and to describe the health professionals involved. We sent a questionnaire to 1252 patients, of whom 985 (79%) responded, aged in average 27 years (range 20-49). Overall, 183 (19%) reported regular, 405 (41%) irregular and 394 (40%) no follow-up. For 344, severity of late effects had been classified in a previous medical examination. Only 17% and 32% of survivors with moderate and severe late effects respectively had made regular visits a decade later. Female gender, after a shorter time since diagnosis, had radiotherapy, and having suffered a relapse predicted follow-up. In the past year, 8% had seen a general practitioner only, 10% a paediatric or adult oncologist and 16% other health specialists for a cancer related problem. These findings underline the necessity to implement tailored national follow-up programmes.

Oral and intravenous methadone use: some clinical and pharmacokinetic aspects.

A sample of 15 patients participating in an injectable methadone trial and of 15 patients in an oral methadone maintenance treatment, who admitted injecting part or all of their methadone take-home doses, were compared to 20 patients in maintenance treatment who use methadone exclusively by mouth. The present study confirms the poorer general health, the higher levels of emotional, psychological or psychiatric problems, the higher use of illicit drugs, and the higher number of problems related to employment and support associated with the use of the intravenous mode of administration of methadone. As expected, due to the shunt of metabolism in the gut wall and of the liver first-pass effect, higher concentration to dose ratios of (R)-methadone, which is the active enantiomer, were measured in the intravenous group (23% increase). This difference reached an almost statistically significant value (P = 0.054). This raises the question whether the effect of a higher methadone dose could be unconsciously sought by some of the intravenous methadone users.

Evolution of anaesthesia care and related events between 1996 and 2010 in Switzerland.

BACKGROUND: Anaesthesia Databank Switzerland (ADS) is a voluntary data registry introduced in 1996. Its ultimate goal is to promote quality in anaesthesiology. METHODS: The ADS registry analyses routinely recorded adverse events and provides benchmark comparisons between anaesthesia departments. Data collection comprises a set of 31 variables organised into three modules, one mandatory and two optional. RESULTS: In 2010, the database included 2,158,735 anaesthetic procedures. Over time, the proportions of older patients have increased, the largest group being aged 50-64 years. The percentage of patients with American Society of Anesthesiologists (ASA) status 1 has decreased while the percentage of ASA status 2 or 3 patients has increased. The most frequent comorbidities recorded were hypertension (21%), smoking (16%), allergy (15%) and obesity (12%). Between 1996 and 2010, 125,579 adverse events were recorded, of which 34% were cardiovascular, 7% respiratory, 39% technical and 20% non-specific. The most severe events were resuscitation (50%), oliguria (22%), myocardial ischaemia (17%) and haemorrhage (10%). CONCLUSION: Routine ADS data collection contributes to the monitoring of trends in anaesthesia care in Switzerland. The ADS system has proved to be usable in daily practice, although this remains a constant challenge that is highly dependent on local quality management and quality culture. Nevertheless, success in developing routine regular feedback to users to initiate discussions about anaesthetic events would most likely help strengthen departmental culture regarding safety and quality of care.

Rapid Improvement In Health-Related Quality Of Life In Gouty Arthritis Patients Treated With Canakinumab (Acz885) Compared To Triamcinolone Acetonide

Background : Canakinumab, a fully human anti-IL-1b antibody has been shown to control inflammation in gouty arthritis. This study evaluated changes in health-related quality of life (HRQoL) in patients treated with canakinumab or triamcinolone acetonide (TA).Methods : An 8-wk, dose-ranging, active controlled, single-blind study in patients (_18 to _80 years) with acute gouty arthritis flare, refractory to or contraindicated to NSAlDs and/or colchicine, were randomized to canakinumab 10, 25, 50, 90, 150mg sc or TA 40mg im. HRQoL was assessed using patient reported outcomes evaluating PCS and MCS, and subscale scores of SF-36_ [acute version 2]) and functional disability (HAQ-DI_).Results : In canakinumab 150mg group, the most severe impairment at baseline was reported for physical functioning and bodily pain; levels of 41.5 and 36.0, respectively, which improved in 7 days to 80.0 and 72.2 (mean increases of 39.0 and 35.6) and at 8 wks improved to 86.1 and 86.6 (mean increases of 44.6 and 50.6); these were higher than levels seen in the general US population. TA group, showed less improvement in 7 days (mean increases of 23.3 and 21.3 for physical function and bodily pain). Functional disability scores, measured by the HAQ-DI_ decreased in both treatment groups (Table 1).Conclusions : Gouty arthritis patients treated with canakinumab showed a rapid improvement in physical and mental well-being based on SF-36_ scores. In contrast to the TA group, patients treated with canakinumab showed improvement in 7 days in physical function and bodily pain approaching levels of the general population.Disclosure statement : U.A., A.F., V.M., D.R., P.S. and K.S. are employees and shareholders of Novartis Pharma AG.

A comparison of the accuracy of peritoneoscopy and liver biopsy in the diagnosis of cirrhosis

The accuracy of peritoneoscopy and liver biopsy in the diagnosis of hepatic cirrhosis was compared in 473 consecutive patients submitted to both procedures. One hundred and fifty-two of them had cirrhosis diagnosed by one or both methods. There was 73% agreement between the two procedures. `Apparent' false-negative results were 17·7% for peritoneoscopy and 9·3% for liver biopsy. The incidence of false-negative results in the diagnosis of cirrhosis can be reduced by combining both procedures.

Synovial fluid examination for the diagnosis of synovial amyloidosis in patients with chronic renal failure undergoing haemodialysis

The diagnosis of synovial amyloidosis is based upon synovial biopsy. Synovial fluid (SF) in seven patients with amyloid arthropathy associated with chronic renal failure undergoing haemodialysis were studied. The SF and synovial samples of 10 consecutive patients with seronegative mono- or oligoarthritis served as controls. Six of the seven patients with amyloid positive synovial biopsy specimens showed amyloid in their SF. No amyloid was found in the synovial tissue or fluid of the 10 patients in the control group, the sensitivity being 87.7%. The finding of amyloid in SF was highly reproducible, showing its presence in the same joint on several occasions. The deposits were Congophilia resistant to potassium permanganate pretreatment, and the immunohistochemical analysis proved that they contained beta 2 microglobulin. The high sensitivity and good reproducibility of the method shows that the finding of amyloid in SF is sufficient for the diagnosis of synovial amyloidosis. It is possible to perform immunohis

Role of technetium-99m diphosphonate and gallium-67 citrate bone scanning in the early diagnosis of infectious spondylodiscitis: a comparative study

A comparative study of the parts played by technetium-99m diphosphonate and gallium-67 citrate bone scanning in the early diagnosis of infectious spondylodiscitis is presented. Nineteen patients were included in the study. All patients (11 men aged 19-70 years and eight women aged 18-72 years) had a history of back pain varying in duration from one to 15 weeks. A 99mTc diphosphonate bone scan was positive in 17 patients. The two patients with negative results had less than two weeks of back pain. The 67Ga citrate bone scan showed uptake in all patients.

ESCMID* guideline for the diagnosis and management of Candida diseases 2012: patients with HIV infection or AIDS.

Mucosal candidiasis is frequent in immunocompromised HIV-infected highly active antiretroviral (HAART) naive patients or those who have failed therapy. Mucosal candidiasis is a marker of progressive immune deficiency. Because of the frequently marked and prompt immune reconstitution induced by HAART, there is no recommendation for primary antifungal prophylaxis of mucosal candidiasis in the HIV setting in Europe, although it has been evidenced as effective in the pre-HAART era. Fluconazole remains the first line of therapy for both oropharyngeal candidiasis and oesophageal candidiasis and should be preferred to itraconazole oral solution (or capsules when not available) due to fewer side effects. For patients who still present with fluconazole-refractory mucosal candidiasis, oral treatment with any other azole should be preferred based on precise Candida species identification and susceptibility testing results in addition to the optimization of HAART when feasible. For vaginal candidiasis, topical therapy is preferred.
