Invasive Fungal Rhinosinusitis

Background. Invasive fungal rhinosinusitis with orbital complications (IFSwOC) is a life-threatening condition. The incidence of mortality has been reported to be up to 80 percent. This study was conducted to determine the risk factors, presentations, clinical, and imaging findings that could help to manage this condition promptly.Methods. We conducted a case-control study of 100 patients suffering from rhinosinusitis with orbital complications. The risk factors, clinical presentations, radiological findings, medical and surgical managements, durations of hospital stay, and mortality rate data were collected.Results. Sixty-five patients were diagnosed with IFSwOC, while the other thirty-five patients composed the control group. The most important risk factor for IFSwOC was diabetes mellitus. Visual loss and diplopia were the significant symptom predictors. The significant clinical predictors were nasal crust, oculomotor nerve, and optic nerve involvement. The CT findings of IFSwOC were sinus wall erosion and hyperdensity lesions. The mortality rate was 25.71 percent in the IFSwOC group and 3.17 percent in the control group.Conclusions. Invasive fungal rhinosinusitis with orbital complications is symptomatic of a high mortality rate. The awareness of a patient’s risk factors, the presenting symptoms, signs of fungal invasion, and aggressive management will determine the success of any treatment procedures.

Background. Wound dehiscence is a life-threatening complication with the mortality rate up to 25 %. The objective of this study is to identify the risk factors for wound dehiscence after midline laparotomy in adult population. Methods. The case control study of patients, operated from January 2012 to May 2016, was performed. Patients, who underwent repeated laparotomy for wound dehiscence, were the cases group. Each case was matched by 3 control group patients undergoing similar primary operation. Following characteristics were observed: demographic, past medical and social history, concomitant diseases, intraoperative details, postoperative outcomes and were compared between the groups. Difference was significant, if p value was less than 0.05. Results. 100 patients were included in the study. There were 25 (25 %) patients of the cases group and 75 (75 %) patient of the control group. The majority of the patients were males (69 %). The mean age was 66.7 ± 10.8 years. Three risk factors were identified in the univariate analysis: male gender (88.0 %), wound infection (56 %) and cardiovascular diseases (88 %) for wound dehiscence with the mortality rate of 20 %. Conclusions. Wound dehiscence is a serious complication with a high mortality rate. The identification of preoperative and early postoperative risk factors may allow preventing and reduce the rate of wound dehiscence.

Background: The greatest risks to life are in its very beginning. Although a good start in life begins well before birth, it is just before, during, and in the very first hours and days after birth that life is most at risk. This prospective case control study was designed on maternal risk factors for perinatal mortality.Methods: This was a case control study conducted in the Department of Obstetrics and Gynecology and Department of Paediatrics, Medical College Trivandrum for one year period in 2004-2005. The cases were all the fresh and macerated still births and early neonatal death cases during the study period. The controls were chosen as the next delivery entry in the OR register.Results: During this period, the total number of deliveries was 14,796 and there were 431 perinatal deaths. The perinatal mortality rate was 29.12. This was much higher compared to Kerala’s perinatal mortality rate of 10, the reason being that the study is conducted in a tertiary referral hospital with one of the best new born care nurseries and a large number of referrals. The most significant risk factors for perinatal mortality were low socio-economic status, referrals, late registration, prematurity, low birth weight, intra-uterine growth restriction, maternal diseases like gestational hypertension and gestational diabetes and intrapartum complications like abruption.Conclusions: Perinatal mortality rate serves as the most sensitive index of maternal and neonatal care. Good antenatal care and prevention of preterm birth may play a key role in further reduction of PMR.

Objective: The aim of this study was to determine the risk factors associated with early childhood caries (ECC).Methods: It was an observational retrospective case-control study. The case group consisted of all patients diagnosed with ECC in the records of an active program of maternal and child care. The control group was composed of an equal number of children, matched for gender and age, who attended the program and did not have ECC. The process of data collection consisted of completing a pre-established schedule to analyse variables related to the mother/caregiver and child.Statisticalanalysis was performed using the chi-squared and odds ratio (OR), with alpha (α) = 0.05.Results: History of caries in the mother (OR=2.61; CI 95%=1.45-4.67) and father (OR=1.72; CI 95%=1.02-2.89) were key determinants in the child being diagnosed with ECC.Conclusions: The risk factors associated with ECC were the following: no oral hygiene acceptance, nocturnal feeding duration of more than 16 months, a daily intake of sugar greater than 4 times a day, a Baume type II maxillary arch, fewer than 3 consultations with the program, and a history of decay in the parents.

AbstractThe bronchoscopy, though usually safe, is occasionally associated with complications, such as pneumonia. However, the use of prophylactic antibiotics is not recommended by the guidelines of the British Thoracic Society. Thus far there are few reports of the risk factors for post-bronchoscopy pneumonia; the purpose of this study was to evaluate these risk factors. We retrospectively collected data on patients in whom post-bronchoscopy pneumonia developed from the medical records of 2,265 patients who received 2666 diagnostic bronchoscopies at our institution between April 2006 and November 2011. Twice as many patients were enrolled in the control group as in the pneumonia group. The patients were matched for age and sex. In total, 37 patients (1.4%) had post-bronchoscopy pneumonia. Univariate analysis showed that a significantly larger proportion of patients in the pneumonia group had tracheobronchial stenosis (75.7% vs 18.9%, p < 0.01) and a final diagnosis of primary lung cancer (75.7% vs 43.2%, p < 0.01) than in the control group. The pneumonia group tended to have more patients with a history of smoking (83.8% vs 67.1%, p = 0.06) or bronchoalveolar lavage (BAL) (4.3% vs 14.9%, p = 0.14) than the control group. In multivariate analysis, we found that tracheobronchial stenosis remained an independent risk factor for post-bronchoscopy pneumonia (odds ratio: 7.8, 95%CI: 2.5–24.2). In conclusion, tracheobronchial stenosis was identified as an independent risk factor for post-bronchoscopy pneumonia by multivariate analysis in this age- and sex- matched case control study.

Introduction Invasive fungal rhinosinusitis is a challenging condition that can be found mostly in immunocompromised patients. Failure to diagnose and treat this entity promptly usually results in rapid progression and death. The purpose of this study was to determine clinical presentation, complication and morbidity in patients with acute versus chronic invasive fungal rhinosinusitis. Setting and design Case-control study at Srinagarind Hospital, Khon Kaen University between January 1998 and May 2008. Methods The patient's data with the diagnosis of invasive fungal rhinosinusitis was included. Demographic data, underlying diseases, presenting symptoms, histologic sinonasal tissue evaluations, sinonasal tissue cultures, CT scan findings, surgical interventions, morbidity, and mortality were collected. Results Sixty-five patients were diagnosed as invasive fungal rhinosinusitis between January 1998 and May 2008. The data of six patients were unable to obtain. Fifty-nine patients were included in this study. Patients with immunocompromised status have significant greater risk for acute than chronic IFS, OR = 6.5 ( P = 0.004). Patients with mucosal necrosis have the significant higher risk for acute IFS, OR = 5.5 ( P = 0.01). There was no significant difference in orbital complications proportion between acute and chronic invasive fungal rhinosinusitis, OR = 2.42 ( P = 0.15). Sinus wall erosion have found significantly in chronic IFS group, OR = 0.24 ( P = 0.02). The average hospital stayed was 30.58 ± 26.43 days with no difference between groups ( P = 0.50). Fourteen patients in acute IFS group were dead (31.11%) while all patients in chronic IFS group were survived. Conclusions Invasive fungal rhinosinusitis continues to present a challenge to the otolaryngologist. Acute IFS was found most commonly in immunocompromised patients. The most consistent finding of acute IFS was mucosal necrosis and black crust/debris. The CT finding of sinus wall erosion may help in diagnosis of chronic IFS.

Objectives: Maternal mortality is one indicator to assess a nation’s health care quality. This research was conducted to determine the determinant risk factors for maternal mortality. Methods: A retrospective case control study at Dr. Mohammad Hoesin General Hospital for 5 years, with 200 samples consists of 50 cases of maternal mortality and 150 physiological labor cases as control group. Results: For 5 years, there was 109 cases of maternal mortaliy. Of the 50 samples of maternal mortality cases, the most common cause were preeclampsia/eclampsia (50%), followed by hemorrhage (28%). The risk factors were categorized as distant, intermediate, and outcome factors, as stated by McCarthy et al. On bivariate analysis, we found the significance on maternal education and husband’s occupation (distant factors), residence, referral status, numbers of ANC visits, first attendant, labor facility and history of prior medical history (intermediate factors), and also modes of delivery and complications (outcome factors). On the multivariate analysis to determine the most contributing risks factors for maternal mortality, it was found that maternal education and residence were the most influencing factors for maternal mortality (OR 5.74 and 4.65 respectively; p=0.001). Conclusions: The most contributing risks factors for maternal mortality were maternal education and residence.

ObjectiveRecent anticoagulation trials in all-comer cryptogenic stroke patients have yielded equivocal results, reinvigorating the focus on identifying reproducible markers of an atrial myopathy. We investigated the role of excessive premature atrial complexes (PACs) in ischaemic stroke, including cryptogenic stroke and its association with vascular risk factors.Methods and resultsA case–control study was conducted utilising a multicentre institutional stroke database to compare 461 patients with an ischaemic stroke or transient ischaemic attack (TIA) with a control group consisting of age matched patients without prior history of ischaemic stroke/TIA. All patients underwent 24-hour Holter monitoring during the study period and atrial fibrillation was excluded. An excessive PAC burden, defined as ≥200 PACs/24 hours, was present in 25.6% and 14.7% (p<0.01), of stroke/TIA and control patients, respectively. On multivariate regression, excessive PACs (OR 1.97; 95% CI 1.29 to 3.02; p<0.01), smoking (OR 1.58; 95% CI 1.06 to 2.36; p<0.05) and hypertension (OR 1.53; 95% CI 1.07 to 2.17; p<0.05) were independently associated with ischaemic stroke/TIA. Excessive PACs remained the strongest independent risk factor for the cryptogenic stroke subtype (OR 1.95; 95% CI 1.16 to 3.28; p<0.05). Vascular risk factors that promote atrial remodelling, increasing age (≥75 years, OR 3.64; 95% CI 2.08 to 6.36; p<0.01) and hypertension (OR 1.54; 95% CI 1.01 to 2.34; p<0.05) were independently associated with excessive PACs.ConclusionsExcessive PACs are independently associated with cryptogenic stroke and may be a reproducible marker of atrial myopathy. Prospective studies assessing their utility in guiding stroke prevention strategies may be warranted.

Abstract Background: Ectopic pregnancy (EP) is defined as a pregnancy in which fertilized oocyte implants outside the endometrial cavity. Although there is no known etiology for ectopic pregnancy, some risk factors of EP have been determined. It has been evident that ectopic pregnancy can be of multifactorial origin. This multicenter research aims to study risk factors associated with increased risk of ectopic pregnancy in women living in Kabul. Methods: A multicenter case control study was conducted in five tertiary maternity hospitals located in Kabul, Afghanistan. A total of 457 pregnant women were included in this study. In the case group, women with diagnosed ectopic pregnancy, while in control group women with intrauterine pregnancy were included. For each case in this study, two controls were enrolled. Results: The mean (SD) age of women in case group was 27.9 (6) years while in control group it was 26.4 (5.5) years. This difference was not statistically significant. We found a significant association between history of abortion and EP (Adj. OR=1.57; 95%CI: 1.02, 2.42). Having history of abdominal/pelvic surgery was a risk factor for EP with adjusted OR 1.94 (95%CI: 1.15, 3.30). In this study we found an increasing risk of EP in women of 35 years or older compared to younger women (Crude OR=2.26; p= 0.024). In women reporting prior EP, the chance of its recurrence was increased (Crude OR= 9.64; 95%CI: 1.1, 83.2). No association of gravidity and parity was found with EP incidence. Conclusions: In this study we found a statistically significant association between history of abdominal/pelvic surgery and EP. In addition, history of abortion was suggested as a risk factor for ectopic pregnancy. In case of having a previous EP probability of its recurrence will be increased. Women with advanced age having other potential risk factors will be facing higher risk of EP.
