Myasis is due to parasitic infestation of the human body by the larvae of brachycere diptera commonly known as maggots. The particular case is described on an anecdotal basis, since the practising ENT specialist may bear the diagnosis in mind, in particular if the patient comes from an area of proximity to a breeding establishment. The interest of the present publication thus lies in the need to bear the diagnosis in mind, since the key is essentially a request for a serological examination. Treatment consists of simple and careful surgical removal of the lesions. The best treatment is prophylactic, by destruction of the insect by organic phosphorous insecticides on the skin of animals.

This is a case report of myiasis in modified radical mastoidectomy cavity in a 48 years old male presented in the Department of ENT and Head and Neck Surgery, T.U. Teaching Hospital, Katmandu, Nepal. Around 50 maggots were removed from his mastoid cavity. Patient was managed with turpentine oil and antibiotics which was given to prevent secondary infection. Literature search revealed only one case report of Myiasis infestation in a postoperative mastoid cavity.

This case of 52-year male with swelling in the left submandibular area for 1 year came to ENT OPD of Patna medical college, Patna. Clinical examination showed swelling to be multiple nontender cysts with enlarged submandibular salivary gland. CT-scan revealed large well-defined encapsulated multicystic lesions in the left submandibular gland. FNAC was suggestive of aspirate to be ectopic to that area. Excision biopsy was done. HPE showed features suggestive of parasitic infestation along with chronic sialadenitis. Gross picture and investigations were highly suggestive of parasitic infestation to be primary hydatid cyst of the gland. Scanning for other areas like liver and lungs done, no lesion was found.

A 74 yr old woman from Gonabad, southern part of Khorasan Razavi Province of Iran was admitted to a Hospital of Gonabad, because of respiratory distress, exertional dyspnea and fever. Close contact with domestic animals, history of chronic obstructive pulmonary disease (COPD), and completely resolved pulmonary tuberculosis (TB) in remote past, were notable parts of her past medical history. Due to clinical, paraclinical and radiographic findings and because of recent hospitalization, she was admitted to internal medicine ward with the diagnosis of health care associated pneumonia (HCAP). Despite the application of broad-spectrum antibiotics and appropriate supportive care, she had a poor response to the treatment. During the daily visit in Intensive Care Unit (ICU), numerous white larvae were detected in both nostrils. Further investigation of oropharynx and tracheal tube aspiration, showed no more larvae in mentioned parts. An hour later, nasal spontaneous bleeding occurred. Otorhinolaryngology consultation was performed and led to surgical procedure. In ENT examination, there were numerous larvae and massive clot formation in both inferior meatuses and distal nasal septum perforation. Thirty-seven extracted larvae were transferred to Medical Entomology lab by vial 70% ethanol and 5 live larvae for rearing. After precise investigation by aid of light microscopy, the larvae were identified as Chrysomya bezziana. Due to discovered 2nd larvae stage and duration of hospitalization, this infestation was identified as nasal myiasis.

Availability of multiple-stress tolerant maize is critical for improvement in maize production in West and Central Africa (WCA). A study was carried out to (i) assess a set of inbred lines for combining ability under stressed and optimal conditions, (ii) determine the performance of the testcrosses under different conditions, and (iii) identify outstanding hybrids across the conditions. Two hundred and five testcrosses were planted with five hybrid checks under Striga-infested, low soil nitrogen, drought and optimal conditions between 2015 and 2016 in Nigeria. The grain yield inheritance under optimal condition was largely regulated by additive gene effect whereas non-additive gene effects largely regulated grain yield under the three stresses. Four of the inbreds had significant positive general combining ability effects each under low N and drought, and three under Striga infestation for grain yield. The inbreds could be vital sources of beneficial alleles for development and improvement of tropical yellow maize hybrids and populations. Hybrids TZEI 443 x ENT 13 and TZEI 462 x TZEI 10 were high yielding and stable; they out-performed the three early maturing released hybrids in WCA. The new hybrids should be extensively assessed and released in the sub-region to improve food security.
