Morphological and Molecular Characterizations of Cochliomyia hominivorax (Diptera: Calliphoridae) Larvae Responsible for Wound Myiasis in French Guiana.

Myiasis is an ectoparasitic infection caused by the larvae of true flies (Diptera). We came across a rather rare case of myiasis in an immunocompetent 34-year-old man from French Guiana with advanced wound myiasis masquerading as cavitary myiasis and a history of cholesteatoma surgery in the left ear. The Diptera larvae responsible for the disease were isolated and identified using morphological and molecular approaches as Cochliomyia hominivorax. We underline the importance of this parasitosis as the second case of myiasis caused by C. hominivorax and the first case of wound myiasis in this overseas department of France and its incidence in pre-urban areas of the capital, Cayenne, in South America.

Occasional human infestations by feral pigeons' ectoparasites: Two case reports.

Dermanyssus infestation is a rural parasitic problem occurs occasionally in urban areas in people with close contact to pigeons. It can be diagnosed through clinical cutaneous symptoms in exposed body parts, nocturnal itching, and presence of mites in infested locations and can be treated by antiacaricide, environmental, and symptomatic treatments.

Luschka Ducts of the Gallbladder in Adults: Case Series Report and Review of the Medical Literature.

Luschka ducts (LD) of the gallbladder (GB) are rare congenital lesions. They are defined as bile ducts that connect directly the hepatic bile duct system to the GB. We aimed to present the characteristics of 55 cases of GB LDs as diagnosed on cholecystectomy specimens. Surgically resected GBs (55) were analyzed for LD morphological features (length, morphological pattern, and epithelial lesions) as well as for immunohistochemical features. The age varied between 24 and 88 years. The gender ratio was 30:25 (female-male). The diagnosis was acute and subacute/chronic cholecystitis (21 and 34 cases, respectively). GB abnormalities of Rokitansky-Aschoff sinus, adenomyoma, septate, and subserosal-liver types were present in 36, 6, 22, and 12 GBs, respectively, while adenocarcinoma was present in 2 GBs. A history of renal cyst, pancreatitis, and colon diverticulosis was observed in 8, 11, and 4 cases, respectively. The LDs were detected at subserosal, resection, or both sites (25, 4, and 26 cases, respectively). The length varied between <1 and 36 mm. Duct-type LDs were observed in 17 cases, complex-type LDs in 5 cases, and mixed-type LDs in 33 cases. Mucosecretion was seen in 12 LDs and cystic dilatation in 8 cases. Epithelial atypia was observed in 2 cases and meganucleoli in 15 cases. Presence of LD-angulation correlated with chronic cholecystitis, while LD-nuclear atypia correlated with acute cholecystitis. In conclusion, LDs may harbor varied aspects, from duct-like or cystic, to nodular, biliary adenoma-like complexes. GB abnormalities of Rokitansky-Aschoff sinus, septa, or subserosal-liver types and extra-GB lesions such as renal cysts, pancreatitis, and colon diverticulosis were associated.

[Imaging findings in intersitial lung diseases]. / Imagerie des pneumopathies infiltrantes diffuses.

Subacute and chronic diffuse interstitial lung diseases Computed tomography (CT) plays an important role in all stages of management: positive diagnosis, etiological diagnosis, evaluation of lesions, ongoing monitoring, screening for complications, and prognosis. The etiological diagnosis is based on the imaging and analysis of patterns or groups of basic lesions often characteristics of a disease. Assessment of the images, the patient history, and the epidemiologic, clinical, laboratory, functional and cytologic data generally make it possible to reach a diagnosis. A pulmonary biopsy is rarely necessary. Acute diffuse interstitial lung diseases In the absence of an obvious clinical direction, CT, electrocardiography, and echocardiography are the first-line examinations to identify or rule out cardiogenic edema. CT can be used to guide bronchoalveolar lavage (BAL), widely used when the patient's respiratory condition permits. BAL can provide a diagnosis of diverse infections or help determine the cytologic type of alveolitis. CT also makes it possible to evaluate the lesions and plays a role in assessing severity. It makes it possible to choose the best sampling method and in principle directs sampling towards the most useful areas. It allows monitoring of disease course, screening of some complications, and precise localizing of tubes, drains, and catheters. Finally, it is used to assess the sequelae.
