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.
Allergic fungal sinusitis (AFS) is a noninvasive form of fungal rhinosinusitis with a prevalence of 6-9 % among all rhinosinusitis cases requiring surgery. The fungi causing AFRS have a great diversity and regional variation in the incidence of AFS has been reported worldwide. The aim of this study was to evaluate the prevalence of AFS among rhinosinusitis patients in the north east of Iran. In a prospective cross-sectional study 127 patients with sinonasal polyposis who were candidates for surgery were recruited. All cases were evaluated by sinonasal CT scan, Prick test for common regional allergens, total serum immunoglobulin E (IgE) level, and allergic mucin culture for fungi in suspected cases. Data analyses were done using SPSS version 13.0. Their mean age was 37.4 ± 11.6 years, the male-to-female ratio was 69/58. Eleven patients (9.45 %) met the AFS criteria. Nine cases had a positive culture for Aspergillus specimen and three for Alternaria. Prick test was positive for at least one allergen in 28 cases (22.05 %). The most common allergen was weed. The total IgE level was significantly higher in AFS patients. This study showed the prevalence of AFS among patients with nasal polyposis to be 9.45 %.
Considering the essential need for oral health-related quality-of-life measures for patients with craniofacial malformations, the current study aimed to investigate the oral health-related quality of life of Iranian patients with cleft lip and palate. Fifty children referred to Cleft lip/Palate Research Center of Mashhad Dental School (Iran) were recruited. Participants were asked to complete the Child Oral Health Impact Profile questionnaire. The questionnaire comprised 38 items and was divided over 5 subscales. The scores on all subscales were compared with regard to patients' age, sex, and type of cleft. A significant difference between boys and girls was found on the subscale "emotional well-being" (P = 0.027). There was no significant difference between 8- to 12-year-old patients and those older than 12 years. Also, no significant difference was found between bilateral and unilateral cleft lip and palate patients regarding mean score of Child Oral Health Impact Profile questionnaire and its subscales. Oral health-related quality of life of cleft lip and palate patients did not change with patients' age. Also, the impact of unilateral and bilateral clefts on OHRQoL was similar. Quality of life of girls was more affected by oral health.
The aim of the present study was to investigate the prevalence of dental anomalies in a group of patients with cleft lip and palate (CL/P) in the northeast of Iran. Ninety-one patients referring to the Cleft Lip and Palate Clinic of Mashhad Dental School were enrolled and classified into right CL/P, left CL/P, and bilateral CL/P groups. Photographs, dental casts, and panoramic and periapical radiographs were retrieved, and dental anomalies were recorded. χ test was used to analyze the frequency of dental anomalies according to type of cleft and sex. Missing maxillary lateral incisors was the most frequent dental anomaly, which was slightly higher in the bilateral group (61.1%). There were significantly more cases of missing lateral incisors outside the cleft area in right CL/P (P = 0.015). Peg lateral incisors were observed in 33.3% of bilateral CL/P compared with 28% of right and 23.3% of left unilateral cases. The sample presented rotations of central incisors in the cleft area in 33.3% of bilateral clefts. In unilateral clefts, it occurred more frequently in the right side (48%). Sexual dimorphism appeared only for maxillary central incisor rotation in the cleft area, which showed significantly greater frequency in females (P = 0.025). Transposition of maxillary canine and first premolars was found in 5.5% of bilateral, 8% of right, and 3.3% of left unilateral clefts. The prevalence of dental anomalies in the studied sample seems to be higher than that reported in the normal population. More anomalies were observed at the cleft side. The frequency of most anomalies was not significantly different between the 2 sexes.
Acute fatty liver of pregnancy (AFLP) is an idiopathic disorder with an unknown cause occurring in late pregnancy. The treatment in these patients is often immediate termination of pregnancy, and plasmapheresis provides an effective treatment option. In this paper, we introduce three pregnant women treated with plasmapheresis. The first case was a 22-year-old primigravida woman treated with 22 sessions of plasmapheresis due to AFLP, hepatic and renal failure, coagulopathy, and ventilator-dependent respiratory failure. The second case was a 23-year-old woman in her second pregnancy treated with 4 plasmapheresis sessions due to AFLP, hepatic and renal failure, coagulopathy, and hypoglycemia. The third patient was a 23-year-old primigravida woman treated with 3 plasmapheresis sessions due to AFLP, renal failure, and coagulopathy. Plasmapheresis can be a life-saving treatment in patients with AFLP and is strongly recommended for patients with severity of their disease accompanied by other organ disorders. In addition, shortening the time interval between the termination of pregnancy and initializing plasmapheresis improves the outcome and reduces the duration of hospital stay and sessions of plasmapheresis.
BackgroundPost intubation long segment tracheal stenosis is a serious problem which usually requires multiple methods of treatment. The aim of this study was to evaluate the results of surgical treatment in long segment post intubation tracheal stenosis.MethodsBetween 2004 to 2008, 20 patients with proximal long segment tracheal stenosis and resection of over 40% of tracheal length, were analyzed in terms of age, sex, clinical symptoms, etiology of stenosis, length of stenosis and resection, role of suprahyoeid release with bilateral hyoeid bone cutting maneuver, post operative complications and life quality 3 year after surgery.ResultsM/F was 2/5, with the average age of 23.5 ± 0.5 years. Average length of stenosis was 4.2 ± 0.4 cm and the average length of resected segment was 5.2 ± 0.4 cm. Early postoperative complications occurred in 4 patients (20%), 5 patients (25%) had late stenosis and 4 of them were treated with multiple dilation and one patient needed tracheostomy and prolonged T. tube. We didn’t have any mortality. 80% of patients had excellent surgical results in follow up period.ConclusionSurgery is the best method of treatment in long and multi segment tracheal stenosis.
