Abstract Cronkhite–Canada syndrome (CCS) is a rare acquired polyposis with unknown etiology. To date, >500 cases have been reported worldwide. CCS is typically characterized by gastrointestinal symptoms, such as diarrhea and skin changes (e.g. alopecia, pigmentation, and nail atrophy). Endoscopic features include diffuse polyps throughout the entire gastrointestinal tract, except for the esophagus. Pathological types of polyps in CCS mainly include inflammatory, hyperplastic, hamartomatous, and adenomatous polyps. CCS can be complicated by many diseases and has a canceration tendency with a high mortality rate. Moreover, there is no uniform standard treatment for CCS. A review of the reported cases of CCS is presented herein, with the goal of improving our understanding of this disease.

Abstract Background Primary amebic meningoencephalitis (PAM) is a rapidly progressive and often fatal condition caused by the free-living ameba Naegleria fowleri. To estimate the global occurrence, characterize the epidemiology, and describe the clinical features of PAM, we report a series of PAM cases published in the international literature and reported to the Centers for Disease Control and Prevention (CDC). Methods We performed a literature search of PAM case reports published through 2018. Additionally, we included cases reported through the CDC’s Free-Living Ameba surveillance or diagnosed via CDC’s Free-Living and Intestinal Amebas Laboratory. Cases were classified as confirmed, probable, or suspect on the basis of confirmatory testing, presentation, exposure, and disease course. Results A total of 381 PAM cases were identified. Seven reported survivors were classified as confirmed. The most commonly reported exposure associated with PAM was swimming/diving, and the most common class of water source was lakes/ponds/reservoirs. Patients were predominantly male (75%), with a median age of 14 years. Confirmed and probable cases were similar in their survival, course of illness, and cerebrospinal fluid (CSF) findings. Conclusions PAM is a rare but deadly disease with worldwide occurrence. Improved clinician awareness, resulting in earlier diagnosis and treatment, may contribute to increased survival among PAM patients. The case definition of probable used in this study appears to capture cases of PAM, as evidenced by similarities in outcomes, clinical course, and CSF profile to confirmed cases. In the absence of confirmatory testing, clinicians could use this case definition to identify cases of PAM.

ABSTRACT We present the chromosome sequences of a Naegleria fowleri isolate from a human primary amebic meningoencephalitis (PAM) case. The genome sequences were assembled from Illumina HiSeq and PacBio sequencing data and verified with the optical mapping data. This led to the identification of 37 contigs representing 37 chromosomes in N. fowleri.

Parasitic Burden

An unusually high mortality rate due to verminous (Philometra rubra) coelomitis was documented in wild-hatched striped bass Morone saxatilis raised in a fish hatchery as part of a stock restoration program. To decrease the parasitic burden and therefore potentially minimize mortality, the effectiveness of 2 different anthelmintics was evaluated. Two trials were conducted on wild-collected fingerlings naturally infected by P. rubra. In 2006, 144 yearling fish were randomly assigned to 4 experimental groups: (1) levamisole (Levasol®) at 2 mg l-1 via immersion for 8 h once weekly for 3 wk; (2) levamisole at a dose of 2.5 mg kg-1 biomass via feed once daily for 7 d; (3) emamectin benzoate (Slice®) at a dose of 0.05 mg kg-1 biomass via feed once daily for 7 d; and (4) control. Emamectin successfully eliminated live nematodes in 84.9% of the fish, whereas the administration of levamisole, either via immersion or feed, was not successful in significantly reducing the number of live P. rubra. In 2007, the administration of the same dosage of emamectin to approximately 1000 naturally infected yearling striped bass was associated with a 100% mortality rate of P. rubra in the 30 fish randomly examined 5 wk after the beginning of the treatment. Results of these trials indicate that, at the dosage used, the administration of emamectin at the end of the summer is safe for striped bass yearlings and considerably reduces the prevalence and intensity of the infection by this parasite.

Tamangapa village, Ma’rang district is part of the community development program conducted by Universitas Muslim Indonesia in Pangkajene Kepulauan regency. The local shrimp farmers of Tamangapa village have been facing major issue due to expensive artificial feed and high mortality rate. In order to solve the needs of feed and high mortality rate for farmed fish or shrimp, the source of the natural ingredients using kopasanda leaves Chromolaena odorata L is required. The use of a natural ingredient is also used to prevent the vibriosis using simple technology such as the utilization of local raw materials which is affordable and locally available. The present community service aimed to provide the proper knowledge and skills to members of the fish/shrimp farmer’s group through counseling, training and mentoring. This community service program encouraged the local farmers to be able to utilize the local raw materials as a source of shrimp feed, use the feed pellet machine, and packaging leading to independent feed production. The participatory training method, lectures, forum group discussions, and practices of making shrimp feed and packaging were applied. The Implementation of the Community Partnership Program of Shrimp and Fish Cultivation Groups is independently able to produce organic fish or shrimp feed for farmer’s group leading to higher productivity of aquaculture.

Pathogenic free-living amoeba are known to cause a devastating infection of the central nervous system and are often referred to as “brain-eating amoebae”. The mortality rate of more than 90% and free-living nature of these amoebae is a cause for concern. It is distressing that the mortality rate has remained the same over the past few decades, highlighting the lack of interest by the pharmaceutical industry. With the threat of global warming and increased outdoor activities of public, there is a need for renewed interest in identifying potential anti-amoebic compounds for successful prognosis. Here, we discuss the available chemotherapeutic options and opportunities for potential strategies in the treatment and diagnosis of these life-threatening infections.

Serious Infection

Fungal endocarditis, specifically from Candida species, is a rare but serious infection with a high mortality rate. Most cases occur in bioprosthetic or mechanical valves and are uncommon in native, structurally normal valves. When Candida endocarditis is detected and appropriate treatment is initiated earlier, there is an improvement in mortality. While the recommendation is usually to treat with a combination of surgery and antifungal medications, patient comorbidities may limit treatment options.

Abstract Background In patients who are critically ill with COVID-19, multiple extrapulmonary manifestations of the disease have been observed, including gastrointestinal manifestations. Case presentation We present a case of a 65 year old man with severe COVID-19 pneumonia that developed hypercoagulation and peritonitis. Emergent laparotomy was performed and we found bowel necrosis in two sites. Conclusions Although rare, the presentation of COVID-19 with bowel necrosis requires emergency treatments, and it has high mortality rate.
