Differentiated thyroid cancer is a rare disease in children and adolescents and manifests exclusively in the form of papillary thyroid cancer (PTC). We present a rare case of PTC who presented initially with lung symptoms and miliary nodules on chest X-ray. This case emphasises the important differential of miliary mottling of the lungs.A 7-year-old girl presented with history of neck swelling and change in voice for the past 9 months and progressively worsening dyspnoea for 5 months. She was assessed elsewhere and treated with multiple courses of antibiotics without relief, as well as levothyroxine 50 µg daily for new hypothyroidism...

The association achalasia and non tuberculous Mycobacteria lung infection is described in the literature. Most of the time Mycobacterium Fortuitum is responsible of aspiration pneumonia that didn't respond to usual antibiotic therapy. We report a new case about a 15 year-old woman with Allgrove's syndrome history. The chest imaging showed a right pulmonary condensation and the diagnosis was bacteriological. Mycobacterium Fortuitum resistant to Rifampicin, isoniazid, Pyrazinamide and ethamabutol was isolated...

Although pyrazinamide (PZA) is a key component of first and second line tuberculosis treatment regimens, there is no gold standard to determine PZA resistance. Approximately 50% of multidrug-resistant tuberculosis (MDR-TB) and over 90% of extensively drug resistant tuberculosis (XDR-TB) strains are also PZA resistant. pnc A sequencing is the endorsed test to evaluate PZA susceptibility. However, molecular methods have limitations for their wide application.In this study we standardized and evaluated a new method to determine PZA resistance: MODS-Wayne...

As current treatment of tuberculosis is burdensomely long, provoking non-adherence and drug resistance, effective short-course treatments are needed. Using the output-driven parabolic response surface (PRS) platform, we have identified drug regimens that treat tuberculosis more rapidly in mice than the current Standard Regimen used in humans. We show that PRS Regimen III, comprising clofazimine, SQ109, bedaquiline and pyrazinamide, rapidly sterilizes the lung both in conventionally studied BALB/c mice and in C3HeB/FeJ mice, highly susceptible mice that develop massive necrotic granulomatous lung lesions akin to those in humans, achieving relapse-free cure in only 4 weeks (p<0...

Approximately 2 billion people, which is about one third of the world's population, are infected with tuberculosis (TB). Around 10% of infected people will develop active TB at one point in their lifetime. We present a rare case of a 68-year-old male who presented to the emergency department with a 2-week progressive dyspnea. In addition, the patient complained of generalized weakness, subjective fevers, and abdominal pain in the right upper quadrant. Ascites was noted on physical exam, and the patient underwent a diagnostic paracentesis with initial workup that was unrevealing for underlying etiology...

In the present study, electrochemical studies and potentiometric determination of captopril (CAP) drug were presented using a glassy carbon electrode (GCE) and carbon paste electrode (CPE), respectively; which is modified with a synthetic nano-structured molecularly imprinted polymer (MIP). CAP-MIP sample with an average particle size of 95 nm was synthesized using a precipitation polymerization method. The electrochemical behavior of CAP was studied on a MIP modified GCE, in an aqueous solution at pH 3...

INTRODUCTION: Contrasting findings have been published regarding the effect of human immunodeficiency virus (HIV) on tuberculosis (TB) drug pharmacokinetics (PK). OBJECTIVES: The aim of this systematic review was to investigate the effect of HIV infection on the PK of the first-line TB drugs (FLDs) rifampicin, isoniazid, pyrazinamide and ethambutol by assessing all published literature. METHODS: Searches were performed in MEDLINE (through PubMed) and EMBASE to find original studies evaluating the effect of HIV infection on the PK of FLDs...

Pyrazinamide (PZA) is an important component of first-line anti-tuberculosis drugs which is converted into active form, pyrazinoic acid (POA), by Mycobacterium tuberculosis (MTB) pncA gene encoded, pyrazinamidase (PZase). Mutations in pncA are detected in >70% of PZA resistant isolates but, noticeably, not in all. In this study, we selected 18 PZA-resistant but wild type pncA (pncAWT ) MTB isolates. Drug susceptibility testing (DST) of all the isolates were repeated at the critical concentration of PZA drug...

BACKGROUND AND OBJECTIVES: To treat organ transplant patients with mycobacterial infection, physicians need to pay attention to interaction between drugs used against mycobacteria and immunosuppressants. The purpose of this report is to describe the clinical features of and treatment for mycobacterial infection in lung transplant (LTx) recipients. METHODS: To investigate the incidence, treatment, and outcome for mycobacterial infection, we retrospectively reviewed 100 LTx recipients in our program since 2000...

Dear Editor, Eczema is an inflammatory dermatitis mediated by cellular immunity, with an etiology in which environmental, immunological, and genetic factors are involved. Skin inflammation through proinflammatory cytokines creates a favorable environment for microbial antigens and optimal conditions for infection (1). In case of underlying immunosuppression, inflammatory features of dermatitis and superimposed infections are more severe. The presence of minor trauma of the skin in the form of fissures can favor both easier inoculation of some bacterial germs, leading to a dermatitis superinfection, and/or the transcutaneous inoculation of atypical mycobacteria, with a possibility of developing localized types of tuberculous lymphadenitis (TLA)...

Pyrazinamide is an essential first-line antitubercular drug which plays pivotal role in tuberculosis treatment. It is a prodrug that requires amide hydrolysis by mycobacterial pyrazinamidase enzyme for conversion into pyrazinoic acid (POA). POA is known to target ribosomal protein S1 (RpsA), aspartate decarboxylase (PanD), and some other mycobacterial proteins. Spontaneous chromosomal mutations in RpsA have been reported for phenotypic resistance against pyrazinamide. We have constructed and validated 3D models of the native and Δ438A mutant form of RpsA protein...

Drug-resistant tuberculous meningitis has been reported worldwide. Isoniazid mono-resistance is the most frequent cause of drug-resistant tuberculous meningitis, a life-threatening disease. Extensive drug-resistant tuberculous meningitis has also been reported in some isolated case reports. Areas covered: We reviewed the current literature on drug-resistant tuberculous meningitis, as well as drug-resistant tuberculosis. Expert commentary: Drug-resistant tuberculous meningitis is a life-threatening disease and needs prompt diagnosis and treatment...

Although rare, erythema induratum is the most common entity presenting as lobular panniculitis with vasculitis. It is usually caused by a hypersensitivity reaction to Mycobacterium tuberculosis , although other aetiologies have been reported. We present a case of a 73-year-old male with multiple recurring tender erythematous nodules on the backs of both calves and shins. Prior to arrival in our clinic, the patient underwent a 9-month course of isoniazid with no improvement and subsequently received a diagnosis of idiopathic erythema induratum...

This study aimed to identify the epidemio-clinic, diagnostic, therapeutic and evolutionary features of genital tuberculosis (GT) among Tunisian women. We conducted a retrospective, descriptive study in the Department of Infectious Diseases at the La Rabta Hospital, Tunisia, over a period of 15 and a half years (January 2000 - June 2014). All patients hospitalized for genital TB were included in the study. The study focused on 47 cases. The average age of patients was 42.2 years. Eighteen women were from rural areas...

BACKGROUND: In the REMoxTB study of 4-month treatment-shortening regimens containing moxifloxacin compared to the standard 6-month regimen for tuberculosis, the proportion of unfavourable outcomes for women was similar in all study arms, but men had more frequent unfavourable outcomes (bacteriologically or clinically defined failure or relapse within 18 months after randomisation) on the shortened moxifloxacin-containing regimens. The reason for this gender disparity in treatment outcome is poorly understood...
