Reported here is a case of microsporidiasis that occurred in an acute myeloblastic leukemia (AML) -M3 patient who underwent chemotherapy. Fever, cough, expectorate and dyspnea were observed during the therapy. Since this case was considered as adult respiratory distress syndrome due to the chest X-ray and arterial blood gas findings, the male patient was bounded to a mechanical ventilator. As coagulation tests showed compatible findings with disseminate intravascular coagulation (DIC), it was thought to be a case of sepsis originating from the lungs and DIC. Pseudomonas aeruginosa and Staphylococcus aureus were found in the sputum of the patient. Although he was given combined antibiotic therapy, there was no reduction in the fever. A bronchoalveolar lavage (BAL) sample was taken and Microsporidia sp. was found upon staining with Giemsa. The patient died due to sepsis and DIC just before receiving therapy for microsporidiasis. Pulmonary infection with Microsporidia, although classically occurring in patients with HIV infection, may occur rarely in leukemia patients, especially if previously treated with systemic immune suppression. This case reinforces the need to consider Microsporidia as a possible pathogen in immunocompromised patients with pulmonary infections.

Neurotrophic keratitis is a rare corneal disease that is challenging to treat. Corneal neurotization (CN) is among the developing treatments that uses the supraorbital (SON) or supratrochlear (STN) nerve as a donor. Therefore, the goal of this study was to provide the detailed anatomy of these nerves and clarify their feasibility as donors for ipsilateral CN. Both sides of 10 fresh-frozen cadavers were used in this study, and the SON and STN were dissected using a microscope intra- and extraorbitally. The topographic data between the exit points of these nerves and the medial and lateral angle of the orbit were measured, and nerve rotation of these nerves toward the ipsilateral cornea were attempted. The SON and STN were found on 19 of 20 sides. The vertical and horizontal distances between the exit point of the SON and that of the STN, were 7.3±2.1 mm (vertical) and 4.5±2.3 mm, respectively. The mean linear distances between the medial angle and the exit points of each were 22.2±3.0 mm and 14.5±1.9 mm, respectively, and the mean linear distances between the lateral angle and the exit points of the SON and STN were 34.0±2.7 mm and 36.9±2.5 mm, respectively. These nerves rotated ipsilaterally toward the center of the orbit easily. A better understanding of the anatomy of these nerves can contribute to the development and improvement of ipsilateral CN.

This study aimed to determine the prevalence of anti- Toxoplasma gondii antibodies in haemodialysis patients with chronic renal failure (CRF). Methods: One hundred and seventy three haemodialysis patients, and 40 healthy controls, were studied for the prevalence of anti-Toxoplasma gondii antibodies by a micro enzyme-linked immunosorbent assay (ELISA). Anti-T. gondii IgG antibodies were detected in 97 (56.06%) haemodialysis patients and 8 (20%) controls with a statistical significance. In addition, anti-T. gondii IgM antibodies were detected in 1.73% of patients, but none of the controls. In conclusion, a high percentage of positivity for Toxoplasma antibodies in patients with CRF undergoing haemodialysis was noticed, thus parasitological surveys of CRF patients should be periodically performed to prevent the possible dissemination of toxoplasmosis through the dialysis procedure.
