Myiasis is a skin infection caused by developing larvae (maggots) of various Diptera fly species. The two most frequent flies that cause human infestations around the world are Dermatobia hominis (human botfly) and Cordylobia anthropophaga (tumbu fly). Maggots have been found to infest the nose, ear, orbit, tracheostomy wound, face, gums, and serous cavities, among other places. Maggots at the colostomy site are an uncommon occurrence. We report a case of maggots infestation surrounding the colostomy site. We came across a rather rare finding in a patient with advanced inoperable rectum cancer who initially complained of persistent nonspecific pain, discomfort, and foul-smelling discharge from the colostomy site. The issue at hand was identified to be maggots, and their removal alleviated the patient's symptoms. We underline the importance of regularly monitoring stoma sites to avoid maggot infestation, especially in tropical regions.

Although cutaneous larva migrans is more commonly seen in the southeastern US and tropical regions of the world, patients with such parasitic involvement may present in other non-endemic areas for various reasons, particularly travelers returning from tropical vacations. Awareness of the clinical presentation and symptomatology of cutaneous larva migrans is important for all physicians, including those practicing in northern climates, for prompt recognition and effective treatment of the disease. Furthermore, cutaneous larva migrans should be of particular interest to podiatrists, because the infestation commonly involves the feet, and a patient may initially present for treatment of secondary manifestations, ie, dermatitis, pruritus, or infection, as in this case report.

Myiasis is an infestation of living tissue with larvae of dipteran flies that commonly inhabit tropical and subtropical regions. The infection principally affects animals but human cases have been also reported. The larvae commonly invade the contaminated cutaneous structures such as wounds or furuncles, but sometimes can invade inner deeper structures. Many cases of myiasis affecting the newborn infants are globally reported with the highest incidence in rural communities with poor hygienic conditions. In this piece of research, we report a case of umbilical myiasis of an 11-day-old infant from Al-Mikhwah city, South Western Saudi Arabia. Parasitologic examination identified the infestation with tumbu fly (Cordylobia anthropophaga) larvae. The clinical presentation and epidemiology were discussed.

AbstractBrucellosis is a frequent zoonosis in some regions of the world and may cause various symptoms. Neurobrucellosis is a rare but serious complication of the infection. Our case report describes the course of neurobrucellosis in a patient who had received a ventriculoperitoneal shunt in his native country 13 years prior to diagnosis of brucellosis. He initially presented to us with symptoms of peritonitis, which misled us to perform abdominal surgery first. After the diagnosis of neurobrucellosis was confirmed and appropriate antibiotics were initiated, the symptoms soon disappeared. Although the ventriculoperitoneal shunt was subsequently removed, the patient did not develop a symptomatic hydrocephalus further on. This case displays the challenges in diagnosing an infection that occurred sporadically in Europe and may be missed by currently applied routine microbiological workup. Considering the political context, with increasing relocation from endemic areas to European countries, it is to be expected that the cases of brucellosis and neurobrucellosis will rise. Brucellosis should be considered and adequate investigations should be performed.

Xestocephalus Van Duzee is among the most common and widespread genera of Cicadellidae in the temperate and tropical regions of the world. In the present study, 205 specimens of the genus Xestocephalus were collected in Thailand, whereas only a single species of the genus was recorded previously using Malaise trap field sampling, studied by comparative morphology. Seventeen species were recognized, including twelve new species: X. binarius sp. nov., X. chrysanthemum sp. nov., X. cowboyocreus sp. nov., X. densprint sp. nov., X. dimiprocessus sp. nov., X. exproiecturus sp. nov., X. gracilus sp. nov., X. limpidissimus sp. nov., X. malleus sp. nov., X. nonattribus sp. nov., X. recipinams sp. nov., and X. tenusis Liang sp. nov. Four species were recorded in Thailand for the first time: Xestocephalus abyssinicus Heller and Linnavuori, Xestocephalus asper Linnavuori, Xestocephalus ishidae Matsumura, and Xestocephalus toroensis Matsumura. Detailed morphological descriptions of all 17 species are given; photographs of external habitus and male genitalia of the species from Thailand are provided. A checklist of species of the genus is also given, and a key to all Thailand Xestocephalus species is also provided.

Abstract Background The new coronavirus disease 2019 pandemic has spread throughout most of the world. Cerebral venous thrombosis is a rare thromboembolic disease that can present as an extrapulmonary complication in coronavirus disease 2019 infection. Case presentation We report the case of a Hispanic woman with Down syndrome who has coronavirus disease 2019 and presents as a complication extensive cerebral venous thrombosis. Conclusions Cerebral venous thrombosis is a rare thromboembolic disease that can present as an extrapulmonary complication in coronavirus disease 2019 infection. In the absence of clinical and epidemiological data, it is important to carry out further investigation of the risk factors and pathophysiological causes related to the development of cerebrovascular thrombotic events in patients with Down syndrome with coronavirus disease 2019 infection.

The Vertical Distribution

The continuous increase in urbanization has been perceived as a major threat for biodiversity, particularly within tropical regions. Urban areas, however, may still provide opportunities for conservation. In this study focused on Macao (China), one of the most densely populated regions on Earth, we used a comprehensive approach, targeting all the vertical strata inhabited by ants, to document the diversity of both native and exotic species, and to produce an updated checklist. We then compared these results with 112 studies on urban ants to illustrate the dual roles of cities in sustaining ant diversity and supporting the spread of exotic species. Our study provides the first assessment on the vertical distribution of urban ant communities, allowing the detection of 55 new records in Macao, for a total of 155 ant species (11.5% being exotic); one of the highest species counts reported for a city globally. Overall, our results contrast with the dominant paradigm that urban landscapes have limited conservation value but supports the hypothesis that cities act as gateways for exotic species. Ultimately, we argue for a more comprehensive understanding of ants within cities around the world to understand native and exotic patterns of diversity.

Endometrial Endometrioid Adenocarcinoma

Keratin granulomas in the peritoneum are a rare finding with multiple etiologies and can be especially challenging for both the pathologist and the surgeon when these lesions are grossly visible. We report a case of a unique frozen section diagnostic scenario of evaluation of keratin granulomas in the peritoneum of a 47-year-old woman in the setting of multiple potential culprits: endometrial endometrioid adenocarcinoma following fertility sparing treatment, and a concurrent dermoid cyst. We discuss the various etiologies of keratin granulomas in the peritoneum, mechanism of their formation, diagnostic significance, as well as implications of fertility sparing treatments. To the best of our knowledge, this is the only case of keratin granulomas in the peritoneum with multiple distinct potential pathologic culprits as well the only case following fertility sparing treatment.

AbstractTwo cases of bilateral moderate to severe sensorineural hearing loss due to oral administration of metronidazole are reported. There has been only one case report of deafness following metronidazole therapy in the world literature. The hearing loss recovered gradually in a period of four to six weeks following withdrawal of drug and oral steroid therapy. The possible mechanism of ototoxicity is discussed. Awareness by the treating physician of ototoxicity due to any drug is stressed.

Indirect Hemagglutination Test

We present a patient with symptoms of abdominal pain and frequent urination due to a huge mass in the retrovesical region. All imaging modalities revealed a cystic mass containing small daughter cysts located between the urinary bladder and rectum. Its characteristics led us to suspect the presence of a hydatid cyst, and an indirect hemagglutination test for Echinococcus granulosus was found positive. No other involvement of hydatid cystic disease was detected. The primary site for the hydatid disease was therefore regarded as the pelvis, on which only a few cases have been reported previously. The patient started albendazole therapy, but refused operation. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions of the world.
