Tools to implement the World Health Organization End TB Strategy: Addressing common challenges in high and low endemic countries.

AIM: The purpose of this viewpoint is to summarize the advantages and constraints of the tools and strategies available for reducing the annual incidence of tuberculosis (TB) by implementing the World Health Organization (WHO) End TB Strategy and the linked WHO TB Elimination Framework, with special reference to Oman. METHODS: The case-study was built based on the presentations and discussions at an international workshop on TB elimination in low incidence countries organized by the Ministry of Health, Oman, which took place from September 5 to September 7, 2019, and supported by the WHO and European Society of Clinical Microbiology and Infectious Diseases (ESCMID). RESULTS: Existing tools were reviewed, including the screening of migrants for latent TB infection (LTBI) with interferon-gamma release assays, clinical examination for active pulmonary TB (APTB) including chest X-rays, organization of laboratory services, and the existing centres for mandatory health examination of pre-arrival or arriving migrants, including examination for APTB. The need for public-private partnerships to handle the burden of screening arriving migrants for active TB was discussed at length and different models for financing were reviewed. CONCLUSIONS: In a country with a high proportion of migrants from high endemic countries, screening for LTBI is of high priority. Molecular typing and the development of public-private partnerships are needed.

Primary Cytomegalovirus-Related Eosinophilic Pneumonia in a Three-year-old Child with Acute Lymphoblastic Leukaemia: Case report and literature review.

A diagnosis of eosinophilic pneumonia (EP) is rare in patients with acute lymphoblastic leukaemia (ALL). We report a case of EP in association with a primary cytomegalovirus (CMV) infection in a three-year-old Omani child with ALL. The patient presented with fever while undergoing maintenance chemotherapy. He was admitted to the Child Health Department of Royal Hospital, in Muscat, Oman, in November 2011. He was initially thought to have sepsis but failed to respond to antibiotics. Chest computed tomography showed diffuse ground glass lung opacification. Bronchoalveolar lavage (BAL) cytology was consistent with the diagnosis of EP. Polymerase chain reaction tests for CMV were performed on the BAL and blood samples and were both markedly elevated. The patient made a full recovery after treatment with prednisolone and ganciclovir. The association between CMV infection and EP as well as the management of this combination in immunocompromised patients has never been reported in the English literature.

Gastrointestinal Basidiobolomycosis: First case report from Oman and literature review.

Gastrointestinal basidiobolomycosis (GIB) is a rare fungal infection with few reported cases worldwide. We report here the first case diagnosed in Oman in a previously healthy 5-year-old Omani female child who had been thought initially to have an abdominal malignancy. The case was referred to the Royal Hospital, Muscat, Oman, in July 2012. She was treated successfully with surgical resection and prolonged antifungal therapy (voriconazole). Physicians, including clinicians, radiologists and pathologists, should have a high index of suspicion for GIB when a patient presents with an abdominal mass and fever.
