Mycobacterium Haemophilum

Abstract Background Mycobacterium haemophilum is a rare and emerging nontuberculous mycobacteria (NTM). It normally causes localized or disseminated systemic diseases, particularly skin infections and arthritis in severely immunocompromised patients. There have been 5 cases of M. haemophilum ocular infections reported in the literature. Only 1 case presented with scleritis with keratitis. Here, we reported 2 cases of M. haemophilum scleritis. One of them was immunocompetent host and had keratitis with radial keratoneuritis as a presenting sign. Case presentation Case 1: A 52-year-old Thai female with rheumatoid arthritis presented with scleritis. Conjunctival scraping was carried out and the culture result was positive for M. haemophilum. Despite receiving systemic and topical antibiotics, her clinical symptoms and signs worsened. Surgical debridement was performed. After surgery, the lesion was significantly improved and finally turned to conjunctival scarring. Case 2: A 32-year old healthy Thai male without underlying disease presented with nodular scleritis and keratouveitis with multiple radial keratoneuritis. Surgical debridement of the scleral nodule was performed. Initial microbiological investigations were negative. Herpes ocular infections was suspected. Topical antibiotics, oral acyclovir, low-dose topical steroids and systemic steroids were started. The scleral inflammation subsided but later the keratitis relapsed, requiring corneal biopsy. Histopathology of the specimen revealed acid-fast bacteria and M. haemophilum was identified by polymerase chain reaction (PCR) and sequencing. The diagnosis of Mycobacterial keratitis was made. Although using the combination of systemic and topical antibiotics, his clinical status progressively deteriorated. Multiple therapeutic penetrating keratoplasties were required to eradicate the infection. No recurrence was found during the 1-year follow-up in both cases. Conclusions M. haemophilum can cause scleritis and keratitis, even in immunocompenent host. Radial keraoneuritis is first described in M. haemophilum keratitis. NTM keratitis should be considered in the differential diagnosis of patients with radial keratoneuritis. Increased awareness and early diagnosis using appropriate culture conditions and molecular techniques are important for the proper treatment of this infection. Prompt surgical intervention appears to be vital for successful management of M. haemophilum scleritis and keratitis.

The Relationship

Terson's sign (TS) is classically defined as vitreous hemorrhage associated with subarachnoid hemorrhage of aneurysmal origin, being an important predictor of severity, indicating greater morbidity and mortality when compared to patients without the sign. The objective of this study is to review the relationship of Terson syndrome/Terson sign with the prognosis of aneurysmal subarachnoid hemorrhage. A search for original articles, research and case reports was performed on the PubMed, Scielo, Cochrane and ScienceDirect platform, with the following descriptors: Terson sign and subarachnoid hemorrhage. Retrospective, prospective articles and case reports published in the last 5 years and which were in accordance with the established objective and inclusion criteria were selected. Ten (10) articles were selected, in which the available results show an unfavorable prognostic relationship of TS and subarachnoid hemorrhage, because these patients had a worse clinical status assessed on the Glasgow scales ≤ 8, Hunt & Hess > III, Fisher > 3, in addition to intracranial hypertension and location of the aneurysm in the anterior communicating artery complex. The early recognition of this condition described by Albert Terson in 1900 brought an important contribution to neurosurgery, being recognized until nowadays.

Tools And Methods

Recent research has highlighted the growing public health concern arising from mismanagement of malarial and non-malarial febrile illnesses that present with similar clinical symptoms. A retrospective examination of patient records suggests that a syndrome-based diagnosis results in over-diagnosis of malaria. Consequently, interventions to mitigate the frequency of presumptive treatment of fever in malaria-endemic settings have been sought, especially for resourcelimited areas. Guidelines that promote the use of microbiological tests and modern diagnostic kits have demonstrated laudable progress in the ongoing challenge of febrile illness management. However, this has brought attention to other factors like the complication of mixed infections. These issues, which remain significant limitations to current tools and methods in the accurate diagnosis and subsequent therapy of febrile illnesses, call for innovative diagnostic interventions. Advancements in biomedical research over the last decade have led to the introduction of state-of-the-art molecular techniques of omics origin that provide the possibility of diverse applications in disease diagnostics. Here, we present notable challenges in febrile illness management, describe currently available tools and methods for diagnosis, and discuss the opportunities for future progress, including harnessing cuttingedge transcriptional profiling and proteomics technology to detect host immunological signatures during infection.

Abstract Purpose To evaluate the efficacy of Lactobacillus paracasei CNCM I-1572 (L. casei DG®) in both prevention of symptomatic recurrences and improvement of quality of life in patients with chronic bacterial prostatitis (CBP). Methods Patients with CBP attending a single Urological Institution were enrolled in this phase IV study. At enrollment, all patients were treated with antibiotics in agreement with EAU guidelines and then were treated with L. casei DG® (2 capsules/day for 3 months). Clinical and microbiological analyses were carried out before (enrollment, T0) and 6 months (T2) after the treatment. Both safety and adherence to the treatment were evaluated 3 months (T1) after the enrollment. NIH Chronic Prostatitis Symptom Index (CPSI), International Prostate Symptom Score (IPSS) and Quality of Well-Being (QoL) questionnaires were used. The outcome measures were the rate of symptomatic recurrence, changes in questionnaire symptom scores and the reduction of antibiotic use. Results Eighty-four patients were included. At T2, 61 patients (72.6%) reported a clinical improvement of symptoms with a return to their clinical status before symptoms. A time dependent improvement in clinical symptoms with significant changes in NIH-CPSI, IPSS and QoL (mean difference T2 vs T0: 16.5 ± 3.58; − 11.0 ± 4.32; + 0.3 ± 0.09; p < 0.001), was reported. We recorded that L. casei DG® treatment induced a statistically significant decrease in both (p < 0.001) symptomatic recurrence [1.9/3 months vs 0.5/3 months] and antibiotic use [− 7938 UDD]. No clinically relevant adverse effects were reported. Conclusions L. casei DG® prevents symptomatic recurrences and improves the quality of life in patients with CBP, reducing the antibiotic use.

AbstractThere has been a recent increase in the feeding of unconventional diets, including whole-prey diets, to domestic pet cats. Our objective was to characterise faecal microbial populations of domestic cats fed whole and ground (6·35 mm grind) raw 1–3-d-old chicks (Rodent Pro). Faecal samples were collected from neutered male domestic cats (mean age = 5·7 years) fed these diet items in a crossover design. Bacterial DNA was isolated from faecal samples and amplicons of the 16S rRNA V4–V6 region were generated and analysed by 454 pyrosequencing. Faecal microbial populations of cats fed whole v. ground chicks did not differ. During the study, three cats presented with symptoms of infection (anorexia or diarrhoea) and tested clinically positive for Salmonella using a standard PCR method. The remaining cats tested negative. Data were analysed post hoc to test for differences in microbial populations due to clinical status. The predominant genera were Clostridium (9–30 %), unidentified Lachnospiraceae (10–28 %), Blautia (4–19 %), Peptococcus (2–19 %) and Fusobacterium (2–14 %). Faeces of cats testing clinically positive for Salmonella had higher (P ≤ 0·05) proportions of the genera Coprococcus (5·6 v. 0·4 %) and Escherichia (subgenera Shigella; 1·1 v. 0·3 %). Salmonella was not detected in faecal samples utilising the pyrosequencing method; however, there was a shift in microbial populations due to clinical status. The clinical symptoms reported herein may be not only due to the Salmonella itself, but also shifts in other gut microbial populations.

Veterinary Hospital of Education Faculty of Veterinary Medicine, Bogor Agricultural University, received a Golden Retriever with clinical symptoms of anorexia, abdominal pain, vomiting and constipation in April 2016. Blood profile examination showed leukocytosis, erythropenia and low hemoglobin level. Radiographic examination without contrast showed a foreign body which is characterized by a large mass radiopaque in intestinal area. Forty-five minutes after the administration of radiographic contrast, contrast material was still in gastrium and only reached partial intestinal. Endoscopy examination showed there was irritation symptoms of the esophagus to gastrium. Black colored liquid was seen while the endoscope inserted into the gastric. Enterotomy was carried out to remove foreign objects. The foreign body is consisted of bones fragments and the plastic that was eaten by the patient. One week after surgery, the animals showed clinical symptoms and had a good appetite. These case can be prevented by not giving foods that contain animal bones and keeping animals in a dirty environment.

Chilaiditi Syndrome

Background. Chilaiditi syndrome is a phenomenon where there is an interposition of the colon between the liver and the abdominal wall leading to clinical symptoms. This is distinct from Chilaiditi sign for which there is radiographic evidence of the interposition, but is asymptomatic. Case Presentation. Here, we present the case of a patient who, despite having clinical symptoms for a decade, had a delayed diagnosis presumably due to the interposition being intermittent and episodic. Conclusions. This case highlights the fact that Chilaiditi syndrome may be intermittent and episodic in nature. This raises an interesting question of whether previous case reports, which describe complete resolution of the syndrome after nonsurgical intervention, are perhaps just capturing periods of resolution that may have occurred spontaneously. Because the syndrome may be intermittent with spontaneous resolution and then recurrence, patients should have episodic follow-up after nonsurgical intervention.

Background:The objective of this study was to document the worldwide decline of dracunculiasis (Guinea worm disease, GWD) burden, expressed as disability-adjusted life years (DALYs), from 1990 to 2016, as estimated in the Global Burden of Disease study 2016 (GBD 2016). While the annual number of cases of GWD have been consistently reported by WHO since the 1990s, the burden of disability due to GWD has not previously been quantified in GBD.Methods:The incidence of GWD was modeled for each endemic country using annual national case reports. A literature search was conducted to characterize the presentation of GWD, translate the clinical symptoms into health sequelae, and then assign an average duration to the infection. Prevalence measures by sequelae were multiplied by disability weights to estimate DALYs.Results:The total DALYs attributed to GWD across all endemic countries (n=21) in 1990 was 50,725 (95% UI: 35,265–69,197) and decreased to 0.9 (95% UI: 0.5–1.4) in 2016. A cumulative total of 12,900 DALYs were attributable to GWD from 1990 to 2016.Conclusions:Using 1990 estimates of burden propagated forward, this analysis suggests that between 990,000 to 1.9 million DALYs have been averted as a result of the eradication program over the past 27 years.

Coexisting anti-NMDAR and MOG antibody (anti-NMDAR-IgG+/MOG-IgG+)-associated encephalitis have garnered great attention. This study aimed to perform a secondary analysis to determine the clinical features of this disease. We searched several databases for related publications published prior to April 2021. A pooled analysis was conducted with the fixed-effects model using the Mante-Haenszel method (I2 ≤ 50%), or the random-effects model computed by the DerSimonian–Laird method (I2 &gt; 50%). Stata software (version 15.0 SE) was used for the analyses. Nine observational studies and 16 case reports (58 cases with anti-NMDAR-IgG+/MOG-IgG+, 21.0 [8.5, 29.0] years, male 58.6%) were included. The incidences (95%CI) of anti-NMDAR-IgG+/MOG-IgG+ in the patients with serum MOG-IgG+ and CSF anti-NMDAR-IgG+ were 0.09 (0.02–0.19) and 0.07 (0.01–0.19), respectively. The median [IQR] of CSF anti-NMDAR antibody titer was 32 [10, 100], and the serum anti-MOG antibody titer was 100 [32, 320]. The prominent clinical symptoms were encephalitic manifestations, including seizures (56.9%) and abnormal behavior (51.7%), rather than demyelinating manifestations, such as speech disorder (34.5%) and optic neuritis (27.6%). Relapse occurred in 63.4% of anti-NMDAR-IgG+/MOG-IgG+ patients, in whom 50.0% of cases relapsed with encephalitic manifestations, and 53.8% relapsed with demyelinating manifestations. The common MRI changes were in the cortex or subcortex (70.7%) and brainstem (31.0%). 31.3% of patients presented with unilateral cerebral cortical encephalitis with epilepsy and 12.5% displayed bilateral frontal cerebral cortex encephalitis. Anti-NMDAR-IgG+/MOG-IgG+ patients showed more frequent mental behavior (OR, 95%CI, 68.38, 1.36–3,434.37), involuntary movement (57.86, 2.53–1,325.11), sleep disorders (195.00, 7.07–5,380.15), and leptomeninge lesions (7.32, 1.81–29.58), and less frequent optic neuritis (0.27, 0.09–0.83) compared to anti-NMDAR-IgG−/MOG-IgG+ patients and presented more common relapse (5.63, 1.75–18.09), preceding infection (2.69, 1.03–7.02), subcortical lesions (116.60, 4.89–2,782.09), basal ganglia lesions (68.14, 2.99–1,554.27), brainstem lesions (24.09, 1.01–574.81), and spinal cord lesions (24.09, 1.01–574.81) compared to anti-NMDAR-IgG+/MOG-IgG−. In conclusion, anti-NMDAR-IgG+/MOG-IgG+ was rarely observed, but the incidence rate of relapse was very high. The overall symptoms seemed to be similar to those of NMDAR encephalitis.

Since December 2019, the world has been shaken by the spread of a highly pathogen virus, causing severe acute respiratory syndrome (SARS-Cov2), which emerged in Wuhan, China. SARS-Cov2 is known to cause acute pneumonia: the cardinal feature of coronavirus disease 2019 (COVID-19). Clinical features of the disease include respiratory distress, loss of spontaneous breathing, and sometimes neurologic signs such as headache and nausea and anosmia, leading to suppose a possible involvement of the nervous system as a potential target of SARS-CoV2. The chapter will shed light on the recent clinical and experimental data sustaining the involvement of the nervous system in the pathophysiology of COVID-19, based on several case reports and experimental data reporting the possible transmission of SARS-CoV2 throughout the peripheral nerves to the brain cardiorespiratory centers. Thus, understanding the role of the nervous system in the course of clinical symptoms of COVID-19 is important in determining the appropriate therapeutic approach to combat the disease.

Abstract Tobacco is one of the most widely cultivated nonfood cash crops, a source of income, model organism for plant molecular research, a natural pesticide and of pharmaceutical importance. First domesticated in South Americas, the modern-day tobacco (Nicotiana tabacum) is now cultivated in more than 125 countries to generate revenues worth billions of dollars each year. However, the production of this crop is highly threatened by the global presence of devastating infectious agents, which cause huge fiscal loss. These threats have been battled through breeding for acquiring disease resilience in tobacco plants, first, via conventional and now with the use of modern molecular breeding approaches. For efficacy and precision, the characterization of the genetic components underlying disease resistance is the key tool in tobacco for resistance breeding programs. The past few decades have witnessed significant progress in resilience breeding through advanced molecular techniques. The current review discusses history of tobacco breeding since its time of origin till date, highlighting the most widely used techniques and recent advances in molecular research and strategies for resistance breeding. In addition, we narrate the budding possibilities for the future. This review will provide a comprehensive and valuable information for the tobacco growers and researchers to deal with the destructive infectious diseases.
