Investigating the epidemiological and economic effects of a third-party certification policy for restaurants with COVID-19 prevention measures.

This study investigates the effects of a third-party certification policy for restaurants (including bars) that comply with indoor infection-prevention measures on COVID-19 cases and economic activities. We focus on the case of Yamanashi Prefecture in Japan, which introduced a third-party certification policy that accredits facilities, predominantly restaurants, that comply with the designated guidelines. We employ a difference-in-differences design for each of our epidemiological and economic analyses.

[Temporary total fecal diversion--ultimate solution for complex recurrent anal fistula].

Anal fistula is a frequent disease, but complex fistulae are relatively uncommon. The treatment for this pathology remains debated all over the world, and in cases of complex fistulae represents a challenge. We present a 55 years old male, operated more than 40 times in the last 15 years for perianal recurrent fistulas and abscesses.

[Visceral leishmaniasis--surgical aspects].

Visceral Leishmaniasis is a multi-organic parasitic disease caused by an intracellular protozoon named Leishmania Donovani; the mean signs are: weight loss, cough, fever, hepatosplenomegaly, adenopathy and cutaneous lesions; death without treatment is the rule. The main treatment is a conservative one. Surgical treatment is necessary for complications, especially for those intra-abdominally.

[Fournier's gangrene--atypical onset for lower rectal cancer].

The onset for rectal cancer is often revealed by one of its complications. With lower frequency, for the rectum below peritoneal reflexion, the perforative-suppurative onset is possible. We wish to expose a 64 years old woman's case, presenting with Fournier's gangrene as a unique sign of a lower rectal adenocarcinoma.
