Meta-Analysis
The (1→3)-β-D-glucan (BDG) is a component of the fungal cell wall that can be detected in serum and used as an adjunctive tool for the diagnosis of invasive mold infections (IMI) in patients with hematologic cancer or other immunosuppressive conditions. However, its use is limited by modest sensitivity/specificity, inability to differentiate between fungal pathogens, and lack of detection of mucormycosis. Data about BDG performance for other relevant IMI, such as invasive fusariosis (IF) and invasive scedosporiosis/lomentosporiosis (IS) are scarce. The objective of this study was to assess the sensitivity of BDG for the diagnosis of IF and IS through systematic literature review and meta-analysis. Immunosuppressed patients diagnosed with proven or probable IF and IS, with interpretable BDG data were eligible. A total of 73 IF and 27 IS cases were included. The sensitivity of BDG for IF and IS diagnosis was 76.7% and 81.5%, respectively. In comparison, the sensitivity of serum galactomannan for IF was 27%. Importantly, BDG positivity preceded the diagnosis by conventional methods (culture or histopathology) in 73% and 94% of IF and IS cases, respectively. Specificity was not assessed because of lacking data. In conclusion, BDG testing may be useful in patients with suspected IF or IS. Combining BDG and galactomannan testing may also help differentiating between the different types of IMI.

Meta-Analysis
Scedosporium genus as a significant emerging opportunist causes a broad spectrum of disease in not only immunosuppressed but also immunocompetent patients. The lung is one of the most commonly encountered sites of Scedosporium infection. Due to its very high levels of antifungal resistance, surgery has been recommended as an important part in the treatment of pulmonary Scedosporium spp infection, even in immunocompetent cases. However, whether lung surgery could help to reduce the risk of death in immunocompetent patients is not clear.We retrospectively retrieved the records of pulmonary infections with Scedosporium species in immunocompetent patients through a comprehensive literature search. The association of surgery on all-cause mortality was explored using binary logistic regression (BLR). Receiver operating characteristic (ROC) curve analysis was carried out to evaluate the capability of the model.The comprehensive searching strategy yielded 33 case reports and 3 case series in total, with 40 individual patients being included. The overall mortality was 12.50%. The fatality rate was 9.09% (2/22) in cases with surgery and 16.67% (3/18) in cases without surgery (odds ratio, 0.50; 95% confidence interval, 0.07-3.38; P = .48). Consistently, BLR analysis identified no statistical association between surgery and reduced mortality (odds ratio, 1.19; 95% confidence interval, 0.09-15.64; P = .89), after adjusting for age, gender, and antifungal chemotherapy. The area under the ROC curve was 0.88.For immunocompetent patients with pulmonary Scedosporium spp infection, surgical therapy may not be associated with reduced mortality. Surgical excision could be considered but is not imperative in this group of patients.

Review
Osteoarticular mycoses due to non-Aspergillus moulds are uncommon and challenging infections. A systematic literature review of non-Aspergillus osteoarticular mycoses was performed using PUBMED and EMBASE databases from 1970 to 2013. Among 145 patients were 111 adults (median age 48.5 [16-92 y]) and 34 pediatric patients (median age 7.5 [3-15 y]); 114 (79.7%) were male and 88 (61.9%) were immunocompromised. Osteomyelitis was due to direct inoculation in 54.5%. Trauma and puncture wounds were more frequent in children (73.5% vs 43.5%; P = 0.001). Prior surgery was more frequent in adults (27.7% vs 5.9%; P = 0.025). Vertebral (23.2%) and craniofacial osteomyelitis (13.1%) with neurological deficits predominated in adults. Lower limb osteomyelitis (47.7%) and knee arthritis (67.8%) were predominantly seen in children. Hyalohyphomycosis represented 64.8% of documented infections with Scedosporium apiospermum (33.1%) and Lomentospora prolificans (15.8%) as the most common causes. Combined antifungal therapy and surgery was used in 69% of cases with overall response in 85.8%. Median duration of therapy was 115 days (range 5-730). When voriconazole was used as single agent for treatment of hyalohyphomycosis and phaeohyphomycosis, an overall response rate was achieved in 94.1% of cases. Non-Aspergillus osteoarticular mycoses occur most frequently in children after injury and in adults after surgery. Accurate early diagnosis and long-course therapy (median 6 mo) with a combined medical-surgical approach may result in favorable outcome.

An increase is observed in the frequency and diversity of fungal infections in the world and in our country. Improving the quality of patient care in infections due to rare moulds depends on early diagnosis and appropriate treatment. Raising awareness about these infections will facilitate taking the necessary steps for diagnosis and treatment in similar cases. In addition to 165 cases out of 96 studies included in this review article, 28 studies reporting rare mould isolation with limited case information were examined. The number of studies reporting cases that meet the criteria has increased over the years. The most frequently reported mould was Fusarium spp. (n= 74), followed by Scedosporium/Pseudallescheria spp. (n= 20). In 25 of the cases, dematiaceous fungi were isolated. Eye (n= 44), skin/soft tissue (n= 35), disseminated (n= 34) peritoneum (n= 13), respiratory tract (n= 13), sinus (n= 12), central nervous system (n= 10), nail (n= 3) and urinary system (n= 1) involvement was detected in the cases. Two cases due to Scedosporium apiospermum and Fonsecaea pedrosoi started locally but spread over time. Among eye involvements, two outbreak reports in which Fusarium spp. was the causative agent drew attention. Of the patients with disseminated involvement, only two who developed Exophiala dermatitidis infection did not have any conditions affecting the immune system. In all peritoneal infections, the patient had a peritoneal catheter (12 for continuous ambulatory peritoneal dialysis and one for drainage). In seven out of 10 cases with central nervous system involvement, dematiaceous fungi were isolated. Appropriate diagnosis and treatment of cases due to rare mould infections can be improved by providing knowledge on the subject in the world and in our country. In these infections where treatment success is limited, correct identification of the causative agent and application of appropriate treatment provides an advantage for clinical success. In this review article, publications from Turkey in Pubmed, Scopus and TR Directory records were searched based on The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) rules and the situation of rare mould infections in our country have been discussed.
