Acute invasive fungal rhinosinusitis (AIFRS) is a rapidly progressive life threatening infection that is seen most commonly among immunocompromised patients. We present a case series of 18 patients clinically and histopathologically diagnosed with AIFRS with a mean follow-up of 9.11 ± 2.51 months (range 6-17). Demographic data, apparent symptoms and signs, underlying disorders, and outcomes are discussed. The mean age was 39.56 ± 20.66 years (range 2-75). The most common underlying diseases were diabetes mellitus (50 %) and leukemia (44.44 %). Mucosal biopsy confirmed fungal invasion of the nasal mucosa in all cases. The main fungi were Rhizopus oryzae (55.56 %), Absidia mucor (16.67 %), and Aspergillus fumigatus (27.78 %). Headache and facial pain (77.8 %), facial paresthesia (55.6 %), and ophthalmoplegia (33.3 %) were the most common symptoms and signs. Computed tomography and endoscopic findings showed various stages of sinonasal (100 %), pterygopalatine fossa (55.56 %), orbital (44.45 %), and cerebral (5.56 %) involvement. All patients underwent serial surgical debridement (3.78 ± 1.80 times; range 2-8) simultaneously with systemic antifungal therapy and proper management of the underlying disease. The most extreme case with brain involvement survived and recovered with no evidence of recurrent disease following treatment. All patients were considered cured after two endoscopic negative histopathologic evaluations. Three patients (16.67 %) died, one from uncontrolled leukemia and two due to renal failure. AIFRS is a potentially fatal condition, however, early diagnosis and management of the underlying disease accompanied with systemic antifungal and aggressive serial surgical intervention appears to be effective in reducing mortality in most patients.

Bacterial infection is considered a predisposing factor for disorders of the biliary tract. This study aimed to determine the diversity of bacterial communities in bile samples and their involvement in the occurrence of biliary tract diseases. A total of 102 bile samples were collected during endoscopic retrograde cholangiopancreatography (ERCP). Characterization of bacteria was done using culture and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) methods. Antimicrobial susceptibility of the isolates was determined based on the Clinical and Laboratory Standards Institute (CLSI) guidelines and identity of the nucleotide sequences of differentiated bands from the DGGE gels was determined based on GenBank data. In total, 41.2 % (42/102) of the patients showed bacterial infection in their bile samples. This infection was detected in 21 % (4/19), 45.4 % (5/11), 53.5 % (15/28), and 54.5 % (24/44) of patients with common bile duct stone, microlithiasis, malignancy, and gallbladder stone, respectively. Escherichia coli showed a significant association with gallstones. Polymicrobial infection was detected in 48 % of the patients. While results of the culture method established coexistence of biofilm-forming bacteria (Pseudomonas aeruginosa, E. coli, Klebsiella pneumoniae, Enterococcus spp., and Acinetobacter spp.) in different combinations, the presence of Capnocytophaga spp., Lactococcus spp., Bacillus spp., Staphylococcus haemolyticus, Enterobacter or Citrobacter spp., Morganella spp., Salmonella spp., and Helicobacter pylori was also characterized in these samples by the PCR-DGGE method. Multidrug resistance phenotypes (87.5 %) and resistance to third- and fourth-generation cephalosporins and quinolones were common in these strains, which could evolve through their selection by bile components. Ability for biofilm formation seems to be a need for polymicrobial infection in this organ.

The purpose of this study was to cephalometrically evaluate the facial soft-tissue characteristics of adolescent patients with bilateral cleft lip and palate (BCLP) and to compare them with a noncleft control group. Lateral cephalometric radiographs obtained from 56 adolescents with nonsyndromic BCLP (29 boys and 27 girls) were analyzed and compared with 67 control subjects (29 boys and 38 girls) who were matched for sex, age, and ethnicity. All patients had been operated on before the age of 2 years for the surgical repair of cleft lip and palate. None had received any orthopedic or orthodontic treatment. Independent-samples t test revealed that patients with BCLP significantly differed from the control group by having a flatter facial profile, thinner and more retruded nasal base, flatter nasal tip (in males), and reduced upper-lip length. Furthermore, thicker lower-lip pit, shallower mentolabial sulcus, and increased inclination angles of the upper and lower lips relative to the horizontal plane were observed in female patients compared with the normal group. The findings of the current study suggested that adolescent patients with BCLP showed several facial soft-tissue deformities when compared with normal individuals with the same age, sex, and ethnic origin. This study provides objective measures that could lead to better treatment planning and prediction of the need for corrective surgeries in patients with BCLP.
