Pretomanid is an antibiotic medication used for the treatment of multi-drug-resistant tuberculosis affecting the lungs. It is generally used together with bedaquiline and linezolid. It is taken by mouth.The most common side effects include nerve damage, acne, vomiting, headache, low blood sugar, diarrhea, and liver inflammation. It is in the nitroimidazole class of medications.Pretomanid was approved for medical use in the United States in August 2019, and in the European Union in July 2020. Pretomanid was developed by TB Alliance. The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication. Medical uses
Pretomanid is indicated in combination with bedaquiline and linezolid, in adults, for the treatment of pulmonary extensively drug resistant (XDR), or treatment-intolerant or nonresponsive multidrug-resistant (MDR) tuberculosis (TB). History
Pretomanid is the generic, nonproprietary name for the novel anti-bacterial drug compound formerly called PA-824. Pretomanid is referred to as "Pa" in regimen abbreviations, such as BPaL. The "preto" part of the compounds name honors Pretoria, South Africa, the home of a TB Alliance clinical development office where much of the drugs development took place, while the "-manid" stem designates compounds with similar chemical structures. This class of drug is variously referred to as nitroimidazoles or nitroimidazooxazines. Development of this compound was initiated because of the urgent need for new antibacterial drugs effective against resistant strains of tuberculosis. Also, current anti-TB drugs are mainly effective against replicating and metabolically active bacteria, creating a need for drugs effective against persisting or latent bacterial infections as often occur in patients with tuberculosis.
Warty dyskeratoma, also known as an Isolated dyskeratosis follicularis,: 777  is a benign epidermal proliferation with distinctive histologic findings that may mimic invasive squamous cell carcinoma and commonly manifests as an umbilicated (Having a central mark or depression resembling a navel) lesion with a keratotic plug, WD have some histopathologic similarities to viral warts but its not caused by HPV and the majority of these lesions display overall histopathologic features consistent with a follicular adnexal neoplasm. Usually limited to the head, neck, scalp or face and vulva. Lesions are generally solitary and sporadic and may be associated with a follicular unit. Oral involvement, particularly the hard palate, and genital involvement have been reported. it can also be thought of as one of the manifestations of focal acantholytic dyskeratosis, an epidermal reaction pattern that can be seen in several disorders, including Dariers disease and Grovers disease. : 639  But the main Difference between Darier disease and Warty dyskeratoma, is that Darier disease inherited dermatosis (autosomal dominant) consisting of multiple keratotic papules on the face, trunk, and extremities, while WD occurs as an isolated, noninherited, single keratotic nodule mainly confined to the head and neck as mentioned earlier. Differential Diagnosis
Warty dyskeratoma must be differentiated from vulvar dysplasia, Bowenoid papulosis, squamous carcinoma, condyloma, and other viral-induced squamous lesions. See also
