Abstract: The first case of parasitoidism of a Myrmicinae ant by a sarcophagid fly has been observed in the Brazilian Cerrado. The larva of a Helicobia Coquillet (Sarcophagidae) specimen fed on head tissues of an Atta laevigata Smith, 1858 soldier and an adult male fly emerged from a puparium formed outside the host.

With extensive loss of life and well-being seen since the beginning of the SARS-CoV-2 pandemic, the initiation of vaccinations has come with enormous hope towards the end of this pandemic. Detailed discussions regarding the safety and efficacy of these vaccines led to their approval. With such success, there have also been reports of vaccine-associated adverse events—allergic reactions, anaphylaxis, immune thrombocytopenia, and thrombosis. We discuss and report the first case of a healthy young adult male developing extensive thrombosis, after receiving the Ad26.COV2.S (Johnson & Johnson/Janssen) vaccine.

While leaf-cutter ants are thought to collect mainly vegetative plant material, they have also been observed collecting seeds or fruit parts on the forest floor (Alvarez-Buylla & Martínez-Ramos 1990, Kaspari 1996). For example, leaf-cutter ants have been observed carrying considerable numbers of Brosimum alicastrum Sw. and Cecropia spp. seeds into their nests (Wirth 1996) and Leal & Oliveira (1998; pers. comm.) found them foraging on the fruits and seeds of 19 different species of Brazilian cerrado vegetation, including six Miconia species. Under some circumstances, seed removal and relocation by leaf cutter ants might even be sufficient to affect local recruitment patterns of trees. For example, in Costa Rica, Atta cephalotes can remove all fallen fig fruit from beneath a Ficus hondurensis crown in a single night (Roberts & Heithaus 1986), while in Venezuela, seedling recruitment of the savanna tree Tapirira velutinifolia was positively associated with the seed harvesting and seed cleaning activities of the ant Atta laevigata (Farji Brenner & Silva 1996).

AbstractIn Lepidoptera wing reduction is usually restricted to the females. We report a rare case of male brachyptery in the genus Xenomigia Warren, 1906 (Notodontidae: Dioptinae) from the high Andes of Venezuela. At the same time this is the first case of wing reduction in the family Notodontidae (Noctuoidea). The new species Xenomigia brachyptera sp. n. is described and the adult, male genitalia and other structures of the adult morphology are illustrated. Some aspects of wing reduction in Lepidoptera are discussed.

Background. Cystic hygroma (CH), occurs in 1/6000 live births and in 90% of cases develops in age less than 2 years old. They are mainly located in cervicofacial region. Adult-onset CH is very rare. Objective. The aim of this study is to review literature to discuss the clinical presentation, diagnosis, and treatment of CH in adults through a case report of unilocular CH in the axillary region in an adult male from India. Methods. A first case report of unilocular CH in axillary region in an adult male from India is being investigated. Results. Here we report a case of unilocular CH in the axillary region in a 49-year-old male with a 14x16x8 cm cystic swelling in left axilla with a history of aspiration failure. Contrast-enhanced MRI (CEMRI) showed well-defined thin walled, unilocular cystic lesion which appeared hyperintense on T2 & STIR and hypointense on T1W1 and showed thin peripheral rim of enhancement on post contrast images. The patient underwent surgical excision and the diagnosis of a pathological CH was established. His postoperative recovery was uneventful and had no evidence of recurrence. Conclusion. Due to rarity of adult-onset unilocular CH in axilla, its evaluation for prompt diagnosis and definitive treatment to prevent recurrence and complications is urgent. Furthermore, this is the first reported case from India which has been successfully managed at a peripheral hospital in Northeast-India and our report of this case contributes to the evidences supporting the role of CH in a differential diagnosis for masses in the adult axilla, especially in acute phase with no predisposing factors.

Necrophilia is a reproductive behavior were a live animal attempts to mate with a dead conspecific. This behaviour has been reported in several lizard species. Here, we report the first case of necrophilia of an adult male Sceloporus zosteromus with a dead conspecific female in northwestern Baja California, Mexico.

AbstractOral pathological conditions are common in mammals and have been relatively well documented for some wild groups, but are rarely reported in marine mammals. Here, we report for the Mexican Caribbean the first case of mandibular osteomyelitis in a free-ranging dolphin. A bottlenose dolphinTursiops truncatusadult male (256.5 cm total length) was found stranded dead in the west coast of the State Reserve “Chetumal Bay Manatee Sanctuary”. Herein, we discuss some plausible explanations about the origin of this lesion to improve the knowledge about the species biology.

Abstract BACKGROUND Intracranial meningiomas are most common among patients in their fifth to seventh decade of life, typically found in older women. Meningiomas are rare in children and young adults; they represent 1–3% of all intracranial tumors in individuals up to age 20 years and 13.5% of intracranial tumors in the 20–34 age group. Meningioma in young adult male is a rare finding. Management of meningioma is similar between young or older patient. The prognosis is depent on the histology finding and type of resection. This case series was made to report an uncommon case including clinical characteristic and management of meningioma in young adult male. MATERIAL AND METHODS We reported 2 cases of meningioma in young adult male. The first patient was hospitalized on 2016 and diagnosed with atypical meningioma (WHO grade II). The second patient was hospitalized on 2018 and diagnosed with trantitional meningioma (WHO grade I). RESULTS First case: 23 y.o male was hospitalized because of severe headache. His physical exam showed weakness of his left side of the body. There was diplopia that significant for bilateral six nerves palsy. Funduscopy examination revealed papil edema in both eyes correlated with his complained of blurry visions. There was no cranial irradiation from his past medical history. Second case, a male 22 y.o was because of decreased of visual acquity progressively since two month before. There was history of throbbing headache in his left head with mild to moderate intensity. On his neurological examination, there was mild weakness in his right body side. Visual acquity on his right and left eyes were 1/300 and 1/60. Bilateral papil edema was found in funduscopy examination. In his past medical history, there was no history of cranial iradiation. Both cases showed similar initial symptoms consist of headache and others neurological deficit. Radiological examination was performed with result leading to meningioma in convexity area in both cases. Craniotomy tumor removal with gross total resection as simpson grade 2 was achieved in both patients. In the second case pre-operative embolization was performed in order to achieve optimal resection. Histopathology examination confirmed as atypical (WHO grade II) in the first case and trantitional Meningioma (WHO grade I) in second case. Follow up imaging post operation showed no residual mass lesion in both patients. There were no further management in these patients. Both of patients showed improvement in their neurologic function and able to activity without restriction in daily living. Serial imaging examination is planned to observe reccurence of the tumor. CONCLUSION Clinical presentation and management of meningioma in these patients are similar as meningioma commonly. Both of patients showed clinical improvement after craniotomy tumor removal succesfully.

We describe a case of intracranial arachnoid cyst rupture leading to ipsilateral subacute subdural haemorrhage secondary to scuba diving in a previously healthy adult male. Our patient required urgent trephination of the cranium to evacuate the subdural haemorrhage and recovered well post operatively. To our knowledge this is the first case reported in the literature of arachnoid cyst rupture with concomitant subdural haemorrhage from scuba diving.  This case may have implications for information provided to patients with arachnoid cysts.
