Microbiota restoration for recurrent Clostridioides difficile: Getting one step closer every day!

Clostridioides difficile infection (CDI) is an urgent health threat being the most common healthcare-associated infection, and its management is a clinical conundrum. Over 450 000 infections are seen in the United States with similar incidence seen in the rest of the developed world. The majority of infections seen are mild-moderate with fulminant disease and mortality being rare complications seen in the elderly and in those with comorbidities. The most common complication of CDI is recurrent infection with rates as high as 60% after three or more infections. A dilemma in the management of primary and recurrent CDI is testing due to the high sensitivity of the nucleic acid amplification tests such as the polymerase chain reaction, which leads to clinical false positives if patients are not chosen carefully (with symptoms) before testing. A newer testing regimen involving a 2-step strategy is emerging using glutamate dehydrogenase as a screening strategy followed by enzyme immunoassay for the C. difficile toxin. Microbiota restoration therapies are the cornerstone of management of recurrent CDI to prevent future recurrences. The most common modality of microbiota restoration is faecal microbiota transplantation, which has been tainted with heterogeneity and adverse events such as serious infectious transmission. The success rates for recurrence prevention from microbiota restoration therapies are over 90% compared with less than 50% of recurrence prevention with courses of antibiotics. This has led to development and emergence of standardized microbiota restoration therapies in capsule and enema forms. Capsule-based therapies include CP101 (positive phase II results), RBX7455 (positive phase I results), SER-109 (positive phase III results) and VE303 (ongoing phase II trial). Enema-based therapy includes RBX2660 (positive phase III data). This review summarizes the principles of management and diagnosis of CDI and focuses on emerging and existing data on faecal microbiota transplantation and standardized microbiota restoration therapies.

Thermophilic ligno-cellulolytic fungi: The future of efficient and rapid bio-waste management.

To accelerate the process of decomposition using consortia of thermophilic ligno-cellulolytic fungi, different crop residues viz. sorghum (SG), soybean (SS), maize (MS), sugarcane (SC), cotton (CS) and pigeon pea (PS) with a varied C:N ratio and sawdust (SD) having high lignin content were collected and used for decomposition process. Compost quality assessed by evaluating different maturity and stability indices at five succeeding stages [first mesophilic (M1), thermophilic (T), second mesophilic (M2), cooling (C) and humification (H)]. A significant reduction was observed in the C:N ratio, biodegradability index, nitrification index, ratio of water-soluble carbon to organic nitrogen (WSC/Org.N) with an increase in concomitant over time while Ash (%), organic matter loss (%), CEC/TOC ratio, cellulose biodegradation ratio (BR) and lignin/cellulose ratio were significantly increased with time. By correlation study, biodegradability index (BI) and fluorescein diacetate (FDA) hydrolysis emerged as the most suitable compost maturity and stability parameters, respectively. Principal component analysis (PCA) results confirmed that BI, BR, WSC/Org. N and FDA can be regarded as key indicators for assessing compost quality. Our findings conclude that fungal consortia of Tricoderma viride, Rhizomucor pusillus, Aspergillus awamori and Aspergillus flavus can accelerate decomposition time from 8 to 12 months (which is normal farming practice) to 120 days.

Suppressed heat shock protein response in the kidney of exercise-trained diabetic rats.

Impaired expression of heat shock proteins (HSPs) and increased oxidative stress may contribute to the pathophysiology of diabetes by disrupted tissue protection. Acute exercise induces oxidative stress, whereas exercise training up-regulates endogenous antioxidant defenses and HSP expression. Although diabetic nephropathy is a major contributor to diabetic morbidity, information regarding the effect of HSPs on kidney protection is limited. This study evaluated the effects of eight-week exercise training on kidney HSP expression and markers of oxidative stress at rest and after acute exercise in rats with or without streptozotocin-induced diabetes. Induction of diabetes increased DNA-binding activity of heat shock factor-1, but decreased the expression of HSP72, HSP60, and HSP90. The inflammatory markers IL-6 and TNF-alpha were increased in the kidney tissue of diabetic animals. Both exercise training and acute exercise increased HSP72 and HSP90 protein levels only in non-diabetic rats. On the other hand, exercise training appeared to reverse the diabetes-induced histological changes together with decreased expression of TGF-beta as a key inducer of glomerulosclerosis, and decreased levels of IL-6 and TNF-alpha. Notably, HSP72 and TGF-beta were negatively correlated. In conclusion, impaired HSP defense seems to contribute to kidney injury vulnerability in diabetes and exercise training does not up-regulate kidney HSP expression despite the improvements in histopathological and inflammatory markers.

Efficacy of different methods for detecting the onset of ovarian cyclicity in post-partum Murrah buffaloes.

This study was designed to investigate the sensitivity and specificity of three methods for detecting the onset of cyclicity in post-partum Murrah buffaloes. The methods investigated were visual signs, transrectal ultrasonography, and serum progesterone (P4) assay. For this study, 102 post-partum Murrah buffalo cows were grouped for monitoring their ovarian activity. The first group of buffaloes was between 26 and 35 days post-partum. Thereafter, the buffalo cows that calved were grouped after every 10 days for the study sample. Thus, the study animals were adjudged between 26 and 35, 36-45, 46-55, 56-65, 66-75, 76-85, and 86-95 days post-partum with an average of 30, 40, 50, 60, 70, 80, and 90 days post-partum, respectively. Visual estrus signs were monitored twice daily, and simultaneously, ultrasound examination was carried out at 10 days interval for accessing the presence of corpus luteum (CL). Serum P4 was estimated in the animals which were adjudged cyclic by ultrasound examination, and the assay was repeated after 10 days. The buffalo cows in estrus were inseminated artificially, and pregnancy status was assessed after 30 days post-insemination. In this study, the sensitivity and specificity of visual observation were low (39.37 and 70.73%, respectively) when compared to P4 assay (98.80 and 96.47%) and ultrasound examination (single, 97.59 and 97.59%; double, 100 and 100%), respectively. Furthermore, the sensitivity and specificity of single and double ultrasound examination and P4 assay were comparable. In conclusion, this study reports that single and double ultrasound examination and P4 assay are more efficient than visual observation in detecting the onset of ovarian cyclicity in post-partum Murrah buffaloes.

Surotomycin versus vancomycin in adults with Clostridium difficile infection: primary clinical outcomes from the second pivotal, randomized, double-blind, Phase 3 trial.

BACKGROUND: The available treatment options for Clostridium difficile infection (CDI) are limited by high recurrence rates. Surotomycin was a novel bactericidal cyclic lipopeptide in development to treat CDI that demonstrated non-inferiority to vancomycin in a Phase 2 trial. OBJECTIVES: To assess surotomycin safety and clinical response (non-inferiority versus vancomycin) at the end of treatment (EOT) of CDI. Additionally, to assess surotomycin response over time and sustained response at 30-40 days post-EOT (superiority versus vancomycin). PATIENTS AND METHODS: Patients with CDI were randomized (1:1) to receive twice-daily oral surotomycin 250 mg alternating with twice-daily placebo or four-times-daily oral vancomycin 125 mg for 10 days in this Phase 3, double-blind, multicentre, international trial. Clinical response over time and sustained clinical response were monitored until the end of the trial, through a follow-up period of 30-40 days. Clinical Trial Registration: NCT01598311. RESULTS: A total of 285 and 292 patients with confirmed CDI were randomized to receive surotomycin and vancomycin, respectively. Surotomycin-associated clinical response at EOT was non-inferior to vancomycin (surotomycin/vancomycin: 83.4%/82.1%; difference 1.4%, 95% CI - 4.9, 7.6). Following treatment with surotomycin, both clinical response over time (stratified log-rank test, P = 0.277) and sustained clinical response (63.3%/59.0%; difference 4.3%, 95% CI - 3.6, 12.2) did not demonstrate superiority versus vancomycin at end of trial. Both treatments were generally well tolerated. CONCLUSIONS: Surotomycin demonstrated non-inferiority to vancomycin for CDI clinical response at EOT. Surotomycin did not demonstrate superiority to vancomycin for clinical response over time or sustained clinical response rate.

Matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) for rapid identification of micro-organisms in the routine clinical microbiology laboratory.

The study evaluates the utility of matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS) Vitek MS for identification of microorganisms in the routine clinical microbiology laboratory. From May 2013 to April 2014, microbial isolates recovered from various clinical samples were identified by Vitek MS. In case of failure to identify by Vitek MS, the isolate was identified using the Vitek 2 system (bioMerieux, France) and serotyping wherever applicable or otherwise by nucleic acid-mediated methods. All the moulds were identified by Lactophenol blue mounts, and mycobacterial isolates were identified by molecular identification systems including AccuProbe (bioMerieux, France) or GenoType Mycobacterium CM (Hain Lifescience, Germany). Out of the 12,003 isolates, the Vitek MS gave a good overall ID at the genus and or species level up to 97.7% for bacterial isolates, 92.8% for yeasts and 80% for filamentous fungi. Of the 26 mycobacteria tested, only 42.3% could be identified using the Saramis RUO (Research Use Only) database. VITEK MS could not identify 34 of the 35 yeast isolates identified as C. haemulonii by Vitek 2. Subsequently, 17 of these isolates were identified as Candida auris (not present in the Vitek MS database) by 18S rRNA sequencing. Using these strains, an in-house superspectrum of C. auris was created in the VITEK MS database. Use of MALDI-TOF MS allows a rapid identification of aerobic bacteria and yeasts in clinical practice. However, improved sample extraction protocols and database upgrades with inclusion of locally representative strains is required, especially for moulds.

Relationship of temperament with oestrous behaviour, resumption of ovarian cyclicity and milk yield in post-partum Murrah buffaloes.

This study was designed to investigate the relationship of temperament with oestrus, resumption of ovarian cyclicity and milk yield in post-partum buffaloes. For this study, 102 post-partum Murrah buffaloes were observed for temperament in open paddock and during milking. Based on the temperament score (1-5 score), they were classified into docile, slightly restless, restless, aggressive and nervous. Oestrous behaviour was monitored twice daily in all the buffaloes along with milk yield (weekly), body weight (BW) and body condition score (BCS) at day 0, 30, 60 and 90 post-partum. Based on the temperament score, the number of buffaloes classified as docile, slightly restless, restless and aggressive was 37 (36.27%), 28 (27.45%), 30 (29.41%) and 7 (6.86%), respectively, but none under nervous category. Number of buffaloes resuming cyclicity in various temperaments groups were as follows: docile (n = 35; 94.59%), slightly restless (n = 22; 78.57%), restless (n = 20; 66.67%) and aggressive (n = 7; 85.71%). Temperament was not correlated (p = .128; r=-.152) with oestrous behaviour. But, temperament was correlated (p < .0001; r = .384) with the resumption of cyclicity as docile and slightly restless buffaloes resumed cyclicity (p < .0016) earlier. Temperament of buffaloes was weakly correlated (p = .0017; r=-.306) with milk production with higher (p < .0358) total milk yield in docile (1022 ± 23.75 kg) and slightly restless buffaloes (948 ± 35.86 kg) as compared to other temperament groups. In summary, temperament of post-partum buffaloes was related with resumption of ovarian cyclicity and milk yield, but not oestrous behaviour.

Mid-infrared photodetectors operating over an extended wavelength range up to 90 K.

We report a wavelength threshold extension, from the designed value of 3.1 to 8.9 µm, in a p-type heterostructure photodetector. This is associated with the use of a graded barrier and barrier offset, and arises from hole-hole interactions in the detector absorber. Experiments show that using long-pass filters to tune the energies of incident photons gives rise to changes in the intensity of the response. This demonstrates an alternative approach to achieving tuning of the photodetector response without the need to adjust the characteristic energy that is determined by the band structure.

Clostridium difficile infection after restorative proctocolectomy and ileal pouch anal anastomosis for ulcerative colitis.

AIM: Clostridium difficile infection (CDI) of the ileal pouch following restorative proctocolectomy (RPC) is becoming increasingly recognized. We aimed to understand better (i) the associated risk factors, (ii) treatment practices and (iii) the pouch diversion and failure rate in patients who developed CDI of the pouch after RPC for ulcerative colitis (UC). METHOD: Patients who tested positive for C. difficile of the pouch between 2007 and 2010 were included in the analysis. Data collected included patient demographics, time from RPC to documented CDI, the treatment of CDI and rate of excision of the pouch. RESULTS: Of 2785 patients recorded in the hospital CDI database, 15 had had an RPC with ileal pouch anal anastomosis. The median age was 44 years and the median interval from RPC to first documented episode of CDI was 3 years. Thirteen (81%) patients had had multiple episodes of pouchitis before and after CDI infection, and all were symptomatic at the time of testing for CDI. Within 30 days of the diagnosis of CDI, six (40%) patients were taking immunosuppressive medication, seven (47%) were taking a proton pump inhibitor and 12 (80%) had received antibiotics. Five patients required hospitalization for CDI and four had severe infections characterized by a serum creatinine more than 1.5 times baseline (n = 3) and a white cell count above 15 000 (n = 1). Six patients who underwent endoscopy had severe inflammation of the pouch including the presence of a pseudomembrane in one case. Ten patients were treated with metronidazole alone and five with vancomycin. Two patients had recurrent CDI of the pouch during a median follow-up period of 2.9 years and one had CDI refractory to medical management. This patient required diversion of the pouch with an ileostomy for refractory CDI but no patient required excision of the pouch. CONCLUSION: All 15 patients developing CDI of the pouch were successfully treated with antibiotics and only one required surgery in the form of an ileostomy.

Electrically pumped photonic-crystal terahertz lasers controlled by boundary conditions.

Semiconductor lasers based on two-dimensional photonic crystals generally rely on an optically pumped central area, surrounded by un-pumped, and therefore absorbing, regions. This ideal configuration is lost when photonic-crystal lasers are electrically pumped, which is practically more attractive as an external laser source is not required. In this case, in order to avoid lateral spreading of the electrical current, the device active area must be physically defined by appropriate semiconductor processing. This creates an abrupt change in the complex dielectric constant at the device boundaries, especially in the case of lasers operating in the far-infrared, where the large emission wavelengths impose device thicknesses of several micrometres. Here we show that such abrupt boundary conditions can dramatically influence the operation of electrically pumped photonic-crystal lasers. By demonstrating a general technique to implement reflecting or absorbing boundaries, we produce evidence that whispering-gallery-like modes or true photonic-crystal states can be alternatively excited. We illustrate the power of this technique by fabricating photonic-crystal terahertz (THz) semiconductor lasers, where the photonic crystal is implemented via the sole patterning of the device top metallization. Single-mode laser action is obtained in the 2.55-2.88 THz range, and the emission far field exhibits a small angular divergence, thus providing a solution for the quasi-total lack of directionality typical of THz semiconductor lasers based on metal-metal waveguides.

Terahertz inverse synthetic aperture radar imaging using self-mixing interferometry with a quantum cascade laser.

We propose a terahertz (THz)-frequency synthetic aperture radar imaging technique based on self-mixing (SM) interferometry, using a quantum cascade laser. A signal processing method is employed which extracts and exploits the radar-related information contained in the SM signals, enabling the creation of THz images with improved spatial resolution. We demonstrate this by imaging a standard resolution test target, achieving resolution beyond the diffraction limit.

A randomized double-blind, placebo-controlled trial to evaluate the safety and efficacy of live Bifidobacterium longum CECT 7347 (ES1) and heat-treated Bifidobacterium longum CECT 7347 (HT-ES1) in participants with diarrhea-predominant irritable bowel syndrome.

To determine the efficacy of the probiotic Bifidobacterium longum CECT 7347 (ES1) and postbiotic heat-treated Bifidobacterium longum CECT 7347 (HT-ES1) in improving symptom severity in adults with diarrhea-predominant irritable bowel syndrome (IBS-D), a randomised, double-blind, placebo-controlled trial with 200 participants split into three groups was carried out. Two capsules of either ES1, HT-ES1 or placebo were administered orally, once daily, for 84 days (12 weeks). The primary outcome was change in total IBS-Symptom Severity Scale (IBS-SSS) score from baseline, compared to placebo. Secondary outcome measures were stool consistency, quality of life, abdominal pain severity and anxiety scores. Safety parameters and adverse events were also monitored. The change in IBS-SSS scores from baseline compared to placebo, reached significance in the ES1 and HT-ES1 group, on Days 28, 56 and 84. The decrease in mean IBS-SSS score from baseline to Day 84 was: ES1 (-173.70 [±75.60]) vs placebo (-60.44 [±65.5]) (p < .0001) and HT-ES1 (-177.60 [±79.32]) vs placebo (-60.44 [±65.5]) (p < .0001). Secondary outcomes included changes in IBS-QoL, APS-NRS, stool consistency and STAI-S and STAI-T scores, with changes from baseline to Day 84 being significant in ES1 and HT-ES1 groups, compared to the placebo group. Both ES1 and HT-ES1 were effective in reducing IBS-D symptom severity, as evaluated by measures such as IBS-SSS, IBS-QoL, APS-NRS, stool consistency, and STAI, in comparison to the placebo. These results are both statistically significant and clinically meaningful, representing, to the best of the authors' knowledge, the first positive results observed for either a probiotic or postbiotic from the same strain, in this particular population.

What is already known on this topicIBS is a chronic functional gastrointestinal disorder characterized by abdominal pain, bloating and abnormalities in stool frequency or form. The gut microbiota of people living with IBS differs markedly to the microbiota of healthy individuals. Gut microbiota may play a key role in IBS aetiology and IBS symptoms may be alleviated by modulating the gut microbiota. Several proposed ways to modulate gut health include normalizing the gut microbiota, preventing the overgrowth of pathogenic bacteria, modulating visceral afferent pathways, and enhancing intestinal barrier function. However, significant heterogeneity between studies, study quality and population, study design and concerns about sample size have limited national and supranational bodies from recommending probiotics for IBS. Further well-powered, randomized, repeatable and controlled trials are warranted.What this study addsThe results of this study substantially contribute to the IBS research field, firstly by providing clinically meaningful and statistically significant results from a rigorous, well designed randomized, placebo-controlled trial and secondly, by exploring the use of postbiotics in IBS, an area of research still in its infancy. Probiotic (ES1) and postbiotic (HT-ES1) supplementation significantly reduced IBS symptom severity scores compared to placebo. This study met primary and secondary outcomes and strongly suggest that ES1 and HT-ES1 could be beneficial in the management of IBS.How this study might affect research, practice, or policyThis study adds to the current evidence base, supporting the use of probiotic/postbiotics for IBS. This research could be used to inform health professionals about using probiotics in IBS and help improve the quality of life and wellbeing for people living with the condition.

Anterior neck lipoma with anterior mediastinal extention - a rare case report.

Lipomas are the most common benign mesenchymal tumour. Thirteen percent of lipomas are seen in head and neck region. Anterior neck lipoma is a rare one. Anterior neck lipoma with mediastinal extension is extremely rare. We are presenting a case of 52 years old male reported to Central Referral Hospital, Sikkim Manipal Institute of Medical Sciences, Gangtok, Sikkim with complains of swelling in left side of neck for last 18 months along with occasional history of dyspnoea. Physical examination, ultrasound, computed tomography and fine needle aspiration cytology are in favor of lipoma. Due to its location up to the anterior mediastinum, the surgery could not be done in this hospital and patient was referred to higher center having cardiothoracic surgical back up.

Measurement of the intrinsic linewidth of terahertz quantum cascade lasers using a near-infrared frequency comb.

We report the measurement of the frequency noise power spectral density of a quantum cascade laser emitting at 2.5THz. The technique is based on heterodyning the laser emission frequency with a harmonic of the repetition rate of a near-infrared laser comb. This generates a beatnote in the radio frequency range that is demodulated using a tracking oscillator allowing measurement of the frequency noise. We find that the latter is strongly affected by the level of optical feedback, and obtain an intrinsic linewidth of ~230Hz, for an output power of 2mW.

Mode-locking of a terahertz laser by direct phase synchronization.

A novel scheme to achieve mode-locking of a multimode laser is demonstrated. Traditional methods to produce ultrashort laser pulses are based on modulating the cavity gain or losses at the cavity roundtrip frequency, favoring the pulsed emission. Here, we rather directly act on the phases of the modes, resulting in constructive interference for the appropriated phase relationship. This was performed on a terahertz quantum cascade laser by multimode injection seeding with an external terahertz pulse, resulting in phase mode-locked terahertz laser pulses of 9 ps duration, characterized unambiguously in the time domain.

Integrated injection seeded terahertz source and amplifier for time-domain spectroscopy.

We used a terahertz (THz) quantum cascade laser (QCL) as an integrated injection seeded source and amplifier for THz time-domain spectroscopy. A THz input pulse is generated inside a QCL by illuminating the laser facet with a near-IR pulse from a femtosecond laser and amplified using gain switching. The THz output from the QCL is found to saturate upon increasing the amplitude of the THz input power, which indicates that the QCL is operating in an injection seeded regime.

Pulmonary coccidiomycosis in New Delhi, India.

Coccidioidomycosis is an endemic disease of the western hemisphere. In cases occurring in non-endemic areas, eliciting a history of exposure as well as a high index of suspicion is imperative for timely and accurate diagnosis. In this case, a 65-year-old male presented to our hospital with fever, dry cough and malaise, and on X-ray chest, was found to have a lower lobe consolidation left lung with nodular lesions in both lungs and necrotic mediastinal lymphadenopathy. He lived in Arizona, USA, for 6 months before admission. Pulmonary coccidioidomycosis was confirmed by the isolation of Coccidioides spp. in pure culture from both broncho-alveolar lavage and lung biopsy specimens. The identity of the isolate was confirmed as C. posadasii by gene sequencing. The patient improved after being treated with fluconazole.

Structural changes of Pd13 upon charging and oxidation/reduction.

First-principle generalized gradient corrected density functional calculations have been performed to study the stability of cationic and anionic Pd(13) (+∕-), and neutral Pd(13)O(2) clusters. It is found that while cationic Pd(13) (+) favors a C(s) geometry similar to the neutral Pd(13), both anionic Pd(13)(-) and neutral Pd(13)O(2) favor a compact ~I(h) structure. A detailed analysis of the electronic structure shows that the stabilization of the delocalized 1P and 2P cluster orbitals, and the hybridization of the 1D orbitals with the oxygen atomic p orbitals play an important role in the energetic ordering of C(s) and ~I(h) isomers. A structural oscillation is predicted during an oxidation/reduction cycle of Pd(13) in which small energy barriers between 0.3 and 0.4 eV are involved.

A comparison of the effect of two types of vibration exercise on the endocrine and musculoskeletal system.

BACKGROUND: Whole body vibration (WBV) is a novel training intervention but a comparison of different methods of WBV has rarely been performed. AIM: To compare the short and medium term effects of two regimens of WBV on endocrine status, muscle function and markers of bone turnover. PATIENTS AND METHODS: Over a period of 16 weeks, 10 men with a median age of 33 yrs (range, 29,49), were randomised to stand on the Galileo platform (GP) or Juvent1000 platform (JP) 3 times/wk. The total study duration was 16 weeks with measurements performed in a 4 week period of run-in, 8 weeks of WBV and a 4 week period of washout. These measurements included an assessment of anthropometry, body composition, muscle function and biochemical markers of endocrine status and bone turnover. To assess immediate effects of WBV, measurements were also performed at 60 mins before and 5, 30 and 60 mins after WBV. To assess immediate effects of WBV, measurements were also performed at 60 mins before and 5, 30 and 60 mins after WBV. RESULTS: GP at 22 Hz was associated with an immediate increase in serum GH, rising from 0.07 µg/l (0.04,0.69) to 0.52 µg/l (0.06,2.4) (p=0.06), 0.63 µg/l (0.1,1.18) (p=0.03), 0.21 µg/l (0.07,0.65) (p=0.2) at 5 mins, 20 mins and 60 mins after WBV, respectively. An immediate effect was also observed in median serum cortisol which reduced from 316 nmol/l (247,442) before WBV to 173 nmol/l (123,245) (p=0.01),165 nmol/l (139,276) (p=0.02) and 198 nmol/l (106,294) (p=0.04) at 5 mins, 20 mins and 60 mins after WBV, respectively. Median serum CTX reduced significantly after 8 weeks of WBV training in the GP group from 0.42 ng/ml (0.29,0.90) pre-WBV to 0.29 ng/ml (0.18,0.44) at the end of WBV training (p=0.03). Over the 8 weeks, there was a reduction in median serum cortisol in the GP group from 333 nmol/l (242,445) (pre-WBV) to 270 nmol/l (115,323) (WBV) (p=0.04). None of the changes observed in the JP group reached statistical significance. Neither group showed any significant effect on muscle function, IGF-1, testosterone, leptin, CRP, creatine kinase, insulin or other markers of bone turnover. CONCLUSION: WBV can stimulate GH secretion, reduce circulating cortisol and reduce bone resorption. These effects are independent of clear changes in muscle function and depend on the type of WBV that is administered.

A novel variant of esophageal atresia with tracheo-esophageal fistula with a crossed-over proximal esophageal pouch: a diagnostic dilemma.

Diagnosis of esophageal atresia (EA) with tracheo-esophageal fistula (TEF) can be easily done in newborns with symptoms of excessive salivation and failure to pass infant-feeding tube (IFT) into the stomach. There are many reports in the literature which describe the diagnostic pitfall of this IFT test. We describe a case of a neonate with EA with TEF in which the upper atretic esophageal pouch had grown long enough to reach up to the level of diaphragm, thus allowing the IFT to go up to significant distance from the alveolus giving the radiograph as if the tube is in the upper part of stomach, thus creating a diagnostic dilemma.
