Purpose: Some investigators have reported severe rectal complications after brachytherapy. Due to the low number of such events, their relationship to dosimetric parameters has not been well characterized. Methods and materials: A total of 3126 patients were treated with low dose rate brachytherapy from 1998 through 2010. 2464 had implant alone, and 313 had implant preceded by 44–46 Gy supplemental external beam radiation (EBRT). Post-implant dosimetry was based on a CT scan obtained on the day of implant, generally within 30 min of the procedure. Every patient’s record was reviewed for occurrence of rectal complications. Results: Eight of 2464 patients (0.32%) treated with brachytherapy alone developed a radiation-related rectal fistula. Average prostatic and rectal dose parameters were moderately higher for fistula patients than for patients without a severe rectal complication. For instance, the average R100 was 1.2 ± 0.75 cc for fistula patients, versus 0.37 ± 0.88 cc for non-fistula patients. However, the fistula patients’ values were well within the range of values for patients without a rectal complication. Four patients had some attempt at repair or reconstruction, but long-term functional outcomes were not favorable. Conclusions: Rectal fistulas are a very uncommon potential complication of prostate brachytherapy, which can occur even in the setting of acceptable day 0 rectal doses. Their occurrence is not easily explained by standard dosimetric or clinical factors

In the last years with the increase of bariatric surgery, first of all as a result of new indications, a rise in the incidence of nutrient-related complications has been observed. Currently little is known about the impact of post-bariatric malnutrition and neurological complications. Wernicke's encephalopathy is a severe neurological syndrome which occurs as a result of thiamine deficiency. Wernicke-Korsakoff syndrome must be considered a serious neurological complication of bariatric surgery with significant morbidity and mortality, with rapidly progressing neurological symptoms, and must be treated immediately. We report the case of a 35 years-old male patient, affected by morbid obesity, anxious-depressive syndrome and alcohol use disorder, who after adjustable gastric banding implanted in another hospital developed a severe malnutrition and neurological syndrome. The patient showed poor adherence to the follow-up and to the dietary indications and after all, we needed to place a PEG for enteral nutrition in order to resolve the malnutrition condition and the neurological syndrome. Our experience emphasizes that preoperative selection and assessment of a patient's nutritional status according to guidelines, is required to identify potential problems, and that bariatric surgeons or physicians caring for patient who have undergone bariatric surgery should be familiar with the constellation of nutritional and neurological disorder that may occur after surgery. We want to remark the importance of preoperative selection of the patients, the follow-up and the cooperation between patient and physician in order to obtain the best result and avoid severe complications.

Pancreatic necrosis complicating severe acute pancreatitis is a challenging scenario in contemporary critical care practice; it requires multidisciplinary care in a setting where there is a relatively limited evidence base to support decision making. This commentary provides a concise overview of current management of patients with infected necrosis, focusing on detection, the role of pharmacologic intervention, and the timing and nature of surgical interventions. Fine-needle aspiration of necrosis remains the mainstay for establishment of infection. Pharmacological intervention includes antibiotic therapy as an adjunct to surgical debridement/drainage and, more recently, drotrecogin alfa. Specific concerns remain regarding the suitability of drotrecogin alfa in this setting. Early surgical intervention is unhelpful; surgery is indicated when there is strong evidence for infection of necrotic tissue, with the current trend being toward 'less drastic' surgical interventions.

Objective: To evaluate the therapeutic roles of transcatheter embolization in patients with pseudoaneurysms complicating acute severe pancreatitis. Methods: Seven patients who suffered from pseudoaneurysms complicating acute severe pancreatitis received abdominal angiography and were treated with transcatheter embolization. The angiographic findings, complications related to the procedure and post- embolization, and rebleeding were observed. Results: The pseudoaneurysms developed at the splenic artery (n=5), right gastroepiploic artery (n=1), and left gastric artery (n=1), respectively. Findings of active bleeding were observed in 3 patients. Six of them were embolized with coils, and the bleedings were stopped immediately. Rebleeding occurred 14-60 days after the embolization in 3 patients, and in one of them, another pseudo aneurysm was observed in repeated angiography and was successfully treated by repeated embolization. No causes of bleeding were found in repeated angiography in the other 2 patients, who died from severe hemorrhage. One pseudo aneurysm was embolized with gelfoam granule. The gastrointestinal bleeding was not controlled and the patient died 3 days later. Procedure related complications occurred in 2 patients. One was celiac trunk rupture during angiography, the other was intima dissecting in splenic artery. Severe post procedure complications occurred in none of the patients. Conclusion: Transcatheter embolization is safe and relatively effective in the management of pseudoaneurysms complicating acute severe pancreatitis. (authors)

Objectives Two-stage open reduction and internal fixation (ORIF) and limited internal fixation combined with external fixation (LIFEF) are two widely used methods to treat Pilon injury. However, which method is superior to the other remains controversial. This meta-analysis was performed to quantitatively compare two-stage ORIF and LIFEF and clarify which method is better with respect to postoperative complications in the treatment of tibial Pilon fractures. Methods We conducted a meta-analysis to quantitatively compare the postoperative complications between two-stage ORIF and LIFEF. Eight studies involving 360 fractures in 359 patients were included in the meta-analysis. Results The two-stage ORIF group had a significantly lower risk of superficial infection, nonunion, and bone healing problems than the LIFEF group. However, no significant differences in deep infection, delayed union, malunion, arthritis symptoms, or chronic osteomyelitis were found between the two groups. Conclusion Two-stage ORIF was associated with a lower risk of postoperative complications with respect to superficial infection, nonunion, and bone healing problems than LIFEF for tibial Pilon fractures. Level of evidence 2.

As maternal deaths have decreased worldwide, increasing attention has been placed on the study of severe obstetric complications, such as hemorrhage, eclampsia, and obstructed labor, to identify where improvements can be made in maternal health. Though access to medical care is considered to be life-saving during obstetric emergencies, data on the factors associated with health care decision-making during obstetric emergencies are lacking. We aim to describe the health care decision-making process during severe acute obstetric complications among women and their families in rural Bangladesh. Using the pregnancy surveillance infrastructure from a large community trial in northwest rural Bangladesh, we nested a qualitative study to document barriers to timely receipt of medical care for severe obstetric complications. We conducted 40 semi-structured, in-depth interviews with women reporting severe acute obstetric complications and purposively selected for conditions representing the top five most common obstetric complications. The interviews were transcribed and coded to highlight common themes and to develop an overall conceptual model. Women attributed their life-threatening experiences to societal and socioeconomic factors that led to delays in seeking timely medical care by decision makers, usually husbands or other male relatives. Despite the dominance of male relatives and husbands in the decision-making process, women who underwent induced abortions made their own decisions about their health care and relied on female relatives for advice. The study shows that non-certified providers such as village doctors and untrained birth attendants were the first-line providers for women in all categories of severe complications. Coordination of transportation and finances was often arranged through mobile phones, and referrals were likely to be provided by village doctors.

The purpose of this study was to evaluate the psychometric properties of a new instrument to measure incidence and severity of ostomy complications early in the postoperative period. 71 participants were enrolled, most were men (52%), white (96%), and married or partnered (55%). The mean age of participants was 57 ± 15.09 years (mean ± SD). Fifty-two participants (84%) experienced at least 1 ostomy complication in the 60-day postoperative period. The research setting was 3 acute care settings within a large healthcare system in the Midwestern United States. We developed an evidence-based conceptual model to guide development and evaluation of a new instrument, the Pittman Ostomy Complication Severity Index (OCSI). The OCSI format includes Likert-like scale with 9 individual items scored 0 to 3 and a total score computed by summing the individual items. Higher scores indicate more severe ostomy complications. This study consisted of 2 phases: (1) an expert review, conducted to establish content validity; and (2) a prospective, longitudinal study design, to examine psychometric properties of the instrument. A convenience sample of 71 adult patients who underwent surgery to create a new fecal ostomy was recruited from 3 hospitals. Descriptive analyses, content validity indices, interrater reliability testing, and construct validity testing were employed. Common complications included leakage (60%), peristomal moisture-associated dermatitis (50%), stomal pain (42%), retraction (39%), and bleeding (32%). The OCSI demonstrated acceptable evidence of content validity index (CVI = 0.9) and interrater reliability for individual items (k = 0.71-1.0), as well as almost perfect agreement for total scores among raters (ICC = 0.991, P ≤ .001). Construct validity of the OCSI was supported by significant correlations among variables in the conceptual model (complications, risk factors, stoma care self-efficacy, and ostomy adjustment). OCSI demonstrated acceptable validity and

Full Text Available Modern clinical medicine and surgery problems are associated with infections complications after medical care. In recent years, surgery has made substantial progress related to the new organizational approaches and medical technology specialized medical care to the wounded and injured. However, these gains are offset by a high rate of infectious complications that require finding effective measures emerging infectious complications timely diagnosis and their prevention. Clinical manifestations are often nosocomial in patients with severe injuries and are largely determined by the influence of clinical and pathogenetic risk factors. Such infectious complications require a comprehensive assessment, including microbiological testing. The main causative agents of infectious complications in surgical hospitals are S. aureus, K. pneumoniae, P. aeruginosa, Acinetobacter spp., which can cause bloodstream infections, soft tissue, respiratory and urinary tract infections, especially in debilitated and immunocompromised patients and patients in intensive care units. These micro organisms are dangerous to patients and medical staff, as they can survive for a long time in the hospital environment, as well as to spread from patient to patient in violation of isolation restrictive measures and requirements for hygiene of medical workers hands. Clinical patterns of infection associated with medical care for severe injuries are to the possibility of serial and parallel development, both in different and in the same time frame of local, visceral and generalized infection with prevalence of combined forms of patients surgical hospital with a high risk of nosocomial infection against the background of factors, diagnostic and treatment process and hospital environment, introduction of the agent.

Factors associated with risk for adverse outcome are important considerations in the preoperative assessment of patients for bariatric surgery. As yet, prediction models based on preoperative risk factors have not been able to predict adverse outcome sufficiently. This study aimed to identify preoperative risk factors and to construct a risk prediction model based on these. Patients who underwent a bariatric surgical procedure in Sweden between 2010 and 2014 were identified from the Scandinavian Obesity Surgery Registry (SOReg). Associations between preoperative potential risk factors and severe postoperative complications were analysed using a logistic regression model. A multivariate model for risk prediction was created and validated in the SOReg for patients who underwent bariatric surgery in Sweden, 2015. Revision surgery (standardized OR 1.19, 95% confidence interval (CI) 1.14-0.24, p prediction model. Despite high specificity, the sensitivity of the model was low. Revision surgery, high age, low BMI, large waist circumference, and dyspepsia/GERD were associated with an increased risk for severe postoperative complication. The prediction model based on these factors, however, had a sensitivity that was too low to predict risk in the individual patient case.

Biologic therapies have revolutionized the approach to immune-mediated diseases such as psoriasis. Due to their favorable safety profiles and excellent efficacy, biologic agents are considered the gold standard for moderate-to-severe psoriasis. The aim of this paper is to saliently review the severe and acute complications of the Food and Drug Administration (FDA) approved biologic agents for psoriasis. Reviewed agents include tumor necrosis factor alpha inhibitors (etanercept, infliximab, and adalimumab), interleukin 12/23 inhibitors (ustekinumab), and interleukin 17 (IL-17) inhibitors (secukinumab and ixekizumab). While malignancies, serious infections, and major adverse cardiovascular events have been reported, their association with biologic therapy are not hypothesized as causal. However, IL-17 inhibitors appear to cause exacerbations and new cases of inflammatory bowel disease. While more long-term studies are warranted in understanding the biologic's long-term side effect profile, short-term studies have confirmed that the biologics are some of the safest treatment options for psoriasis. Nevertheless, certain populations yield higher risk to acute complications with the biologics than others - physicians must use their judgement and vigilance when monitoring and treating patients undergoing therapy with biological agents.

Increased of proinflammatory cytokines levels, including interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-alpha) on severe acute pancreatitis causes vasodilatation, increased permeability of the wall, accumulation of fluid in lung tissue and pleural sinuses. Transudate from acute parapancreatyc clusters of hot liquid and abdomen falls into the chest cavity through microscopic defects in the diaphragm due to the formation of pathological pleural-peritoneal connections or the relevant pressure gradient between the abdominal and pleural cavities. Remediation and removal of acute parapancreatyc clusters combined with the use of a multicomponent drug infusion therapy Cytoflavin provide a reduction in the frequency of pulmonary complications of acute pancreatitis from 48.3 to 31.0%. Use of the drug Cytoflavin reduces the severity of endogenous intoxication and mortality from acute lung injury from 12.9 to 6.1%.

We present our management of urethral stenosis and rectourinary fistula resulting from prostate cancer therapy. We concentrated on cases refractory to minimally invasive treatment, such as dilation, urethrotomy, and urinary and/or fecal diversion. In our prospectively collected urethral reconstruction database we identified patients who underwent reconstruction of urethral stenosis or rectourinary fistula who also received prior treatment for prostate cancer. We documented demographics, prostate cancer pretreatment characteristics, prostate cancer therapy type, urethral reconstruction type and success. A total of 48 patients met the inclusion criteria, including 16 with rectourinary fistula and 32 with urethral stenosis. Urethral complications followed prior radical prostatectomy, brachytherapy, external beam radiotherapy, cryotherapy, thermal ablation and any combination of these procedures. Stenosis repair was successful in 23 of 32 cases (73%) and it differed little between anterior and posterior urethral stenosis. Repair was accomplished by anastomotic urethroplasty in 19 cases, flap urethroplasty in 2, perineal urethrostomy in 2 and a urethral stent in 9. Prior external beam radiotherapy was a risk factor for urethral reconstruction failure. Fistula repair was successful in 14 of 15 patients (93%), excluding 1 who died postoperatively. The complexity of fistula management was dictated by fistula size and the presence or absence of coincident urethral stenosis. Urethral stenosis or rectourethral fistula following prostate cancer therapy can be managed by urethral reconstruction, such that normal voiding via the urethra is maintained, rather than abandoning the urethral outlet and performing heterotopic diversion. This can be accomplished with an acceptable rate of failure, given the complexity of the cases.

A 32-year-old man presented to the emergency department with severe right lower limb pain and swelling of three days' duration. He had multiple prior admissions for recurrent seizures and suicide attempts. Markedly elevated serum creatine kinase levels and urine myoglobinuria were consistent with a diagnosis of rhabdomyolysis. Initial magnetic resonance imaging of the right lower limb revealed diffuse muscle oedema and features of myositis in the gluteal muscles and the adductor, anterior and posterior compartments of the thigh. Follow-up magnetic resonance imaging performed 11 days later showed interval development of areas of myonecrosis and haemorrhage. The causes, clinical presentation and imaging features of rhabdomyolysis are discussed. Copyright: © Singapore Medical Association.

CT were performed in thirteen patients (12 women, 1 man) aged from 53 to 90 (mean age, 74) with severe RSH. Five patients also underwent ultrasound examination and three MR examination. Nine patients (69%) were receiving subcutaneous injection of heparin, three (23%) oral anticoagulant therapy and one continuous IV infusion of heparin. Clinical diagnosis was reached in 6 cases. Excessive activity of anticoagulant therapy was noted in 4 cases. The location of the RSH, their densities and their signals were analysed. All the RSH were mostly developed in the lower third of the abdominal wall, had a large spreading into the Retzius space and compressed the bladder and/or the bowels. RSH were all hyperdense and in 8 cases (61%) a fluid-fluid level due to the hematocrit effect was noted. In one case, a retroperitoneal hematoma was discovered. The extension of the RSH was well delineated with MRI. The RSH showed itself with heterogeneous signal intensities with areas of high-signal-intensity on T1-weighted images. Fluid-fluid levels and a concentric ring sign were also noted. Older women with subcutaneous injection of heparin are especially prone to RSH even though there is no overall excessive activity of anticoagulant therapy. Clinical and biological diagnosis may be difficult. CT scan is the exam of choice to reach a precise and acute diagnosis of RSH. (authors). 34 refs., 8 figs

Background Although malnutrition affects thousands of children throughout the Sahel each year and predisposes them to infections, there is little data on the etiology of infections in these populations. We present a clinical and biological characterization of infections in hospitalized children with complicated severe acute malnutrition (SAM) in Maradi, Niger. Methods Children with complicated SAM hospitalized in the intensive care unit of a therapeutic feeding center, with no antibiotics in the previous 7 days, were included. A clinical examination, blood, urine and stool cultures, and chest radiography were performed systematically on admission. Results Among the 311 children included in the study, gastroenteritis was the most frequent clinical diagnosis on admission, followed by respiratory tract infections and malaria. Blood or urine culture was positive in 17% and 16% of cases, respectively, and 36% had abnormal chest radiography. Enterobacteria were sensitive to most antibiotics, except amoxicillin and cotrimoxazole. Twenty-nine (9%) children died, most frequently from sepsis. Clinical signs were poor indicators of infection and initial diagnoses correlated poorly with biologically or radiography-confirmed diagnoses. Conclusions These data confirm the high level of infections and poor correlation with clinical signs in children with complicated SAM, and provide antibiotic resistance profiles from an area with limited microbiological data. These results contribute unique data to the ongoing debate on the use and choice of broad-spectrum antibiotics as first-line treatment in children with complicated SAM and reinforce the call for an update of international guidelines on management of complicated SAM based on more recent data.

Complications following open standing castration (OSC) in Thoroughbred racehorses are well recognised but variation in their prevalence and severity between populations is not well documented. To describe the prevalence and severity of complications in the 30 days following OSC. A retrospective cohort study of veterinary clinical records relating to horses that underwent OSC between July 2007 and July 2012. Complications were graded on a severity score from N, no complications, to C3, severe complications. Additional data were accessed for each horse including age, import date, racing history, trainer and veterinarian performing the castration. Bacterial culture and antimicrobial sensitivities were performed on a limited number of castration wounds that became infected. In total, 250 horses were castrated in Hong Kong using the OSC technique over the period of the study. Sixty percent (150/250) of horses experienced some type of post-castration complication, with eight horses experiencing a severe (C3) complication requiring intensive veterinary treatment. Scrotal swelling, funiculitis and seroma formation were present in 70.0%, 36.7% and 24.7% of cases respectively. Most horses experiencing complications required wound reopening (87.3%; 131/150), and/or an extended course of first-line antimicrobials and/or nonsteroidal anti-inflammatory drugs (75/150; 50.0%). Eight horses had cultures submitted for bacterial sensitivity, with 17 bacterial isolates grown. In vitro, the bacteria cultured were sensitive to enrofloxacin (76%; 13/17) and ceftiofur (100%; 17/17). Resistance was detected to penicillin, gentamicin, oxytetracycline, metronidazole and trimethoprim-sulfadiazine. Differences in post-castration management cannot be accounted for in this study. Complications following OSC in horses in Hong Kong were common. The majority were mild and were successfully treated using antimicrobials and simple wound management. Given the high rate of complications and

Endoscopic removal of asymptomatic common bile duct stones (CBDS) is generally recommended. Although many reports have described the risk of complications in endoscopic retrograde cholangiopancreatography (ERCP), no studies have addressed this problem in the context of asymptomatic CBDS. This study examines the risk of complications arising in ERCP for asymptomatic CBDS. This retrospective study included 425 patients with naive papilla who underwent therapeutic ERCP for choledocholithiasis at 2 institutions in Japan for 2 years. The risk of complications was examined in patients who were divided into the asymptomatic and symptomatic CBDS groups. We used propensity score analysis to adjust for confounding effects. Complications were observed in 32 (7.5 %) of the 425 patients. Of the 358 patients with symptomatic CBDS, 14 patients (3.9 %) had complications. In contrast, of the 67 patients with asymptomatic CBDS, 18 patients (26.9 %) had complications. Propensity score analysis revealed that asymptomatic CBDS was a significant risk factor, with a significantly higher incidence of complications compared with symptomatic CBDS (odds ratio, 5.3). Moderate to severe complications were observed in 15 of 18 patients (83.3 %) in the asymptomatic CBDS group, with significantly more moderate to severe complications than those in the symptomatic CBDS (odds ratio, 6.7). Asymptomatic CBDS carried a high risk of ERCP-related complications, and these were often more severe. In asymptomatic CBDS, endoscopic treatment should be carefully performed after considering the patient's background, and detailed explanation of its possible complications should be given to patients in advance.

The treatment of choice for distal femur malignancies in skeletally immature patients remains controversial. An expandable endoprosthesis device (Repiphysis Limb Salvage System; Wright Medical Technology, Arlington, TN, USA) allows for limb preservation and noninvasive lengthening but has been associated with significant complications; however, the extent and implications of bone loss associated with this implant have not been reported. Our goals were to report (1) the 2-year minimum clinical outcomes after placement of the Repiphysis expandable prosthesis for pediatric distal femur malignancies; (2) the complications associated with this prosthesis; (3) the failure rate of this prosthesis; and (4) the revision alternatives available for salvage procedures. Between 2002 and 2010, one surgeon (SG) treated all skeletally immature patients (mean age, 10.1 years; range, 4.7-13.6 years) with distal femoral osteosarcoma using a Repiphysis expandable prosthesis. Of the 12 patients who met these criteria, two were excluded for death from disease before 2 years, and mean followup for the remaining 10 was 72 months (range, 26-119 months). Medical records were retrospectively reviewed for complications and clinical outcomes, as assessed by the Musculoskeletal Tumor Society (MSTS) scoring system. Radiographs at final followup were reviewed for bone loss and analyzed by the two senior authors (SG, WWV) to determine reconstruction options available for future revisions. MSTS scores averaged 67%, and we observed 37 implant-related complications requiring a total of 15 reoperations. Six patients underwent implant revisions with aseptic loosening being the predominant mode of failure; ultimately, four of these were converted to adult modular oncology prostheses, and two underwent total femoral replacements. Bone loss in this series was severe in terms of femoral length, cortical thinning, and metadiaphyseal compromise, and most patients will not have sufficient bone stock to permit

To document the impact of severe obstetric complications on post-partum health in mothers and mortality in babies over 12 months in Benin and to assess whether severe complications associated with perinatal death are particularly likely to lead to adverse health consequences. Cohort study which followed women and their babies after a severe complication or an uncomplicated childbirth. Women were selected in hospitals and interviewed at home at discharge, and at 6 and 12 months post-partum. Women were invited for a medical check-up at 6 months and 12 months. The cohort includes 205 women with severe complications and a live birth, 64 women with severe complications and perinatal death and 440 women with uncomplicated delivery. Women with severe complications and a live birth were not dissimilar to women with a normal delivery in terms of post-partum health, except for hypertension [adjusted OR = 5.8 (1.9-17.0)], fever [adjusted OR = 1.71 (1.1-2.8)] and infant mortality [adjusted OR = 11.0 (0.8-158.2)]. Women with complications and perinatal death were at increased risk of depression [adjusted OR = 3.4 (1.3-9.0)], urine leakages [adjusted OR = 2.7 (1.2-5.8)], and to report poor health [adjusted OR = 5.27 (2.2-12.4)] and pregnancy's negative effects on their life [adjusted OR = 4.11 (1.9-9.0)]. Uptake of post-natal services was poor in all groups. Women in developing countries face a high risk of severe complications during pregnancy and delivery. These can lead to adverse consequences for their own health and that of their offspring. Resources are needed to ensure that pregnant women receive adequate care before, during and after discharge from hospital. Near-miss women with a perinatal death appear a particularly high-risk group.

Objective: To study severe and rare complications of transarterial chemoembolization (TACE) for liver cancer. Methods: Clinical records of severe and rare complications following TACE in 1348 cases of liver cancer from January 1997 to February 2004 were studied retrospectively. Results: A total of 2012 TACE procedures were performed for 1348 patients. There were 3 cases of spontaneous rupture of liver cancer, 1 case of perforation of duodenum, 3 cases of liver abscess (1 of them was associated with sepsis), 1 case of pulmonary embolism, 1 case of spasm of the hepatic artery, 40 cases of hepatic artery occlusion, 3 cases of femoral nerve injury, 1 case of bilioma and 1 case of acute renal failure. Conclusion: Although the severe complications of TACE are rare, the procedure should be done cautiously including super selection of hepatic artery, slow infusion of lipiodol, careful postoperative observations and early detection and management of complications

In 2009 a new classification of dengue was proposed by WHO Tropical Disease Research, which classifies dengue into dengue (D), dengue with warning signs (DW) and severe dengue (SD). This classification highlights the warning signs of dengue disease severity. Neurological complications are one of the most serious complications of dengue disease. This study was carried out to see association of neurological complications of dengue patients with WHO warning signs for dengue disease severity, and their outcome. Methods: It was a cross-sectional analytical study and included 180 diagnosed and registered cases of dengue hemorrhagic fever. The participants were subjected to a detailed clinical evaluation, laboratory assessment including blood counts, hematocrit, serology for dengue fever and sonography at 24 hours and 48 hours of their admission. Results: Twenty-six percent patients were suffering from neurological complications due to dengue. The warning signs for dengue disease severity like altered sensorium (85.5%, p=0.001), raised hematocrit (n=47, p=0.029), gall bladder wall thickening, pleural effusion and ascites on sonographic report (n=47, p=0.024), were strongly associated with the neurological complications. Conclusion: Our study reveals significant association of WHO warning signs for dengue disease severity with neurological complications of dengue disease. (author)

Involvement of the nervous system in infectious mononucleosis is common. About 50% have headache on presentation. Neck stiffness without meningitis is a frequent finding. Severe neurological complications are rare though, occurring in fewer than 0.5%. We describe two patients with unusual and severe
Full Text Available Introduction. Octogenarians are at increased risk for complications after lung resection. With alternatives such as radiation, understanding the risks of surgery and associated survival are valuable. Data grading the severity of complications and long-term survival in this population is lacking. We reviewed our experience with lobectomy in octogenarians, grading complications using a validated thoracic morbidity and mortality schema. Methods. We retrospectively reviewed consecutive patients aged ≥80 undergoing lobectomy between 2004 and 2012. Demographics, clinical/pathologic stage, complications, recurrence, and mortality were collected. Complications were graded by the Seely thoracic morbidity and mortality model. Results. 45 patients (mean age 82.2 years were analyzed. The majority of patients (28/45, 62% were clinical stage IA/IB. 62% (28/45 of patients experienced a complication. Only 15.6% (7/45 were considered significantly morbid (≥ grade IIIB per the Seely model. Perioperative mortality was 2% and half of patients were living at a follow-up of 53 months. Overall five-year survival was 52%. Conclusions. In carefully selected octogenarians, lobectomy carries a 15.6% rate of significantly morbid complications with encouraging overall survival. These data provide the basis for a more complete discussion with patients regarding lobectomy for lung cancer.

Severe combined immunodeficiency (SCID) is a syndrome characterized by profound T-cell deficiency. BCG vaccine is contraindicated in patients with SCID. Because most countries encourage BCG vaccination at birth, a high percentage of patients with SCID are vaccinated before their immune defect is detected. We sought to describe the complications and risks associated with BCG vaccination in patients with SCID. An extensive standardized questionnaire evaluating complications, therapeutics, and outcomes regarding BCG vaccination in patients given a diagnosis of SCID was widely distributed. Summary statistics and association analysis was performed. Data on 349 BCG-vaccinated patients with SCID from 28 centers in 17 countries were analyzed. Fifty-one percent of the patients had BCG-associated complications, 34% disseminated and 17% localized (a 33,000- and 400-fold increase, respectively, over the general population). Patients receiving early vaccination (≤1 month) showed an increased prevalence of complications (P = .006) and death caused by BCG-associated complications (P vaccine has a very high rate of complications in patients with SCID, which increase morbidity and mortality rates. Until safer and more efficient antituberculosis vaccines become available, delay in BCG vaccination should be considered to protect highly vulnerable populations from preventable complications.

Summary Objective To document the impact of severe obstetric complications on post-partum health in mothers and mortality in babies over 12 months in Benin and to assess whether severe complications associated with perinatal death are particularly likely to lead to adverse health consequences. Methods Cohort study which followed women and their babies after a severe complication or an uncomplicated childbirth. Women were selected in hospitals and interviewed at home at discharge, and at 6 and 12 months post-partum. Women were invited for a medical check-up at 6 months and 12 months. Results The cohort includes 205 women with severe complications and a live birth, 64 women with severe complications and perinatal death and 440 women with uncomplicated delivery. Women with severe complications and a live birth were not dissimilar to women with a normal delivery in terms of post-partum health, except for hypertension [adjusted OR = 5.8 (1.9–17.0)], fever [adjusted OR = 1.71 (1.1–2.8)] and infant mortality [adjusted OR = 11.0 (0.8–158.2)]. Women with complications and perinatal death were at increased risk of depression [adjusted OR = 3.4 (1.3–9.0)], urine leakages [adjusted OR = 2.7 (1.2–5.8)], and to report poor health [adjusted OR = 5.27 (2.2–12.4)] and pregnancy’s negative effects on their life [adjusted OR = 4.11 (1.9–9.0)]. Uptake of post-natal services was poor in all groups. Conclusion Women in developing countries face a high risk of severe complications during pregnancy and delivery. These can lead to adverse consequences for their own health and that of their offspring. Resources are needed to ensure that pregnant women receive adequate care before, during and after discharge from hospital. Near-miss women with a perinatal death appear a particularly high-risk group. PMID:20406426

Severe/medically complicated obesity in childhood, and particularly in adolescence, is a real disability that requires an intensive and continuous approach which should follow the procedures and schedule of rehabilitation medicine. Given the lack of a specific document focusing on children and adolescents, the Childhood Obesity Study Group set out to explore the available evidence for the treatment of severe or medically complicated obesity and to set standards tailored to the specific context of the Italian Health Service. Through a series of meetings and electronic communications, the writing committee (selected from members of the Study Group) selected the key issues, explored the literature and produced a draft document which was submitted to the other experts until the final synthesis was approved by the group. In brief, the following issues were involved: (1) definition and epidemiology; (2) identification of common goals designed to regain functional competence and limit the progression of metabolic and psychological complications; (3) a multi-professional team approach; (4) the care setting. This paper is an expert opinion document on the rehabilitation of severe and medically complicated obesity in children and adolescents produced by experts belonging to the Childhood Obesity Study Group of the Italian Society for Pediatric Endocrinology and Diabetology (ISPED).

We reviewed the clinical and neuroradiological features in 16 patients with serious neurological complications of lumbar epidural anaesthesia. We observed acute, transient or permanent and delayed complications. Four patients had symptoms immediately after the procedure. One patient developed a subacute flaccid paraparesis. Two other patients had infectious spondylodiscitis at lumbar puncture level. Eight patients had a delayed progressive spastic paraparesis and were found to have subarachnoid cysts and irregularities of the surface of the spinal cord consistent with arachnoiditis; six of them had an extensive, complex syrinx within the cord. One patient had a severe lumbar polyradiculopathy, and MRI showed adhesive arachnoiditis involving the cauda equina. Although epidural anaesthesia is generally considered safe, rare but severe complications, such as radiculopathy, infectious disease, myelopathy from ischemia and arachnoiditis with a syrinx may occur. The patients with arachnoiditis had a relentless progression of the disease and a poor outcome: five are confined to a wheelchair, one is bedridden. Complications of epidural anaesthesia are easily recognised when they develop immediately; their relationship to the anaesthesia may be ignored or underestimated when they appear after a delay. Awareness of the possibility of delayed complications is important. (orig.)

Some patient with severe motor and intellectual disabilities have a narrow mediastinum due to severe scoliosis or thoracic deformity. Complication of tracheostomy in these patients, such as granulation of the lower end of the cannula and tracheo-innominate artery fistulae, are difficult to treat. The causes of recurrent respiratory distress after tracheostomy in four patients with severe motor and intellectual disabilities were investigated, and its management was evaluated based on chest CT and bronchoscopy. In all patients, the lower end of the cannula was in contact with the site of tracheal stenosis, accompanied by granulation with arterial pulsation. In three patients, tracheomalacia as a complication of tracheostomy was also noted. In three patients, changing the cannula to fix its lower end proximally to the lesion, combined with stent placement in one patient with tracheomalacia, resulted in regression of the granulation and respiratory distress. However, one patient with severe tracheomalacia, who had been treated by stent placement alone, died of tracheo-innominate artery fistula. To prevent complications of tracheostomy in patients with severe motor and intellectual disabilities, it is important to select cannulas with a suitable length and angle. In the absence of severe tracheomalacia, use of custom-made short cannulas that can be fixed proximally to the site of stenosis and to the proximity of arteries are appropriate for this purpose.

To assess if observed higher observed risks of cardiac complications for patients with Kawasaki disease (KD) treated earlier may reflect bias due to confounding from initial disease severity, as opposed to any negative effect of earlier treatment. We used data from Japanese nationwide KD surveys from 1997 to 2004. Receipt of additional intravenous immunoglobulin (IVIG) (data available all years) or any additional treatment (available for 2003-2004) were assessed as proxies for initial disease severity. We determined associations between earlier or later IVIG treatment (defined as receipt of IVIG on days 1-4 vs days 5-10 of illness) and cardiac complications by stratifying by receipt of additional treatment or by using logistic modeling to control for the effect of receiving additional treatment. A total of 48 310 patients with KD were included in the analysis. In unadjusted analysis, earlier IVIG treatment was associated with a higher risk for 4 categories of cardiac complications, including all major cardiac complications (risk ratio, 1.10; 95% CI, 1.06-1.15). Stratifying by receipt of additional treatment removed this association, and earlier IVIG treatment became protective against all major cardiac complications when controlling for any additional treatment in logistic regressions (OR, 0.90; 95% CI, 0.80-1.00). Observed higher risks of cardiac complications among patients with KD receiving IVIG treatment on days 1-4 of the illness are most likely due to underlying higher initial disease severity, and patients with KD should continue to be treated with IVIG as early as possible.

Full Text Available Acenocoumarol is a vitamin K antagonist that is used for the treatment of acquired and congenital, both arterial and venous, thrombotic diseases. Its use is complicated by the narrow therapeutic range. Bleeding following oral anticoagulation, despite rare, remains the major complication. Most cases of hemorrhagic episodes usually require short hospitalization and transfusion, while surgical drainage of the hematoma is not recommended. However, in cases that conservative treatment isn’t successful, surgical intervention remains an option. We present a case of severe spontaneous bleeding of the rectus abdominis muscle which was successfully managed surgically.

In recent years, large mumps outbreaks, involving mainly adolescents and young adults, have re-emerged in several countries. We investigated a large mumps outbreak, evaluated the association between mumps clinical severity (complications, hospitalization) and vaccination status (number of previous measles, mumps and rubella - MMR vaccine doses), and assessed vaccine effectiveness. The first mumps cases emerged in an ultra-orthodox boys' school in Jerusalem and were epidemiologically linked to the mumps outbreak in New York. Overall, 3130 mumps cases were notified in the Jerusalem district during September 2009-August 2011 (median age 13y, 64% males). Most cases were reported from community clinics. Patients with systemic symptoms and/or complications (419, 13.4%) were either hospitalized (n = 79) or treated in an emergency medical center (n = 340). The main complications included orchitis (3.8% males> age 12y) and meningoencephalitis (0.5%). The mumps virus genotype was G5. The distribution of previous MMR vaccine doses (n = 0,1,2) was: 24.8%, 28.3% and 46.9%, respectively. The number of previous vaccine doses was inversely associated with clinical severity. Adjusted values for MMR vaccine effectiveness against complications were estimated as 52.1% (95% CI -4 -78%) for one vaccine dose and 62.7% (95% CI 25.7-81.3%) for 2 doses. The outbreak was characterized by predominance of male students; the majority of whom had been previously vaccinated. The reported complication rate was relatively low. Vaccination status was associated with age and disease severity. The combination of limited mumps vaccine effectiveness and the specific school setting (dense learning and living conditions) probably contributed to the disease spread.
Full Text Available Objective: Clinical application of autologous fat grafting (AFG is quickly expanding. Despite the widely acceptance, long-term survival rate (SR of AFG remains a question not yet solved. Meanwhile, although rare, severe complications related to AFG including vision loss, stroke even death could be seen in the literature. Data Sources: A comprehensive research of PubMed database to June 2013 was performed according to guidelines of the American Society of Plastic Surgeons Fat Graft Task Force Assessment Methodology. Articles were screened using predetermined inclusion and exclusion criteria. Study Selection: Data collected included patient characteristics, surgical technique, donor site, recipient site, graft amount, and quantified measurement methods. Patient cohorts were pooled, and SR was calculated. All the severe complications were also summarized according to the different clinical characteristics. Results: Of 550 articles, 16 clinical articles and 10 animal studies met the inclusion criteria and provided quantified measurement methods. Totally, 596 patients were included. SR varied from 34% to 82% in breast and 30-83% in the facial area. Nude mice were applied to investigate human fat grafting SR (38.3-52.5% after 15 weeks. Rabbits were commonly used to study animal AFG SR (14.00-14.56% after 1-year. Totally, 21 severe complications were reported, including death (2, stroke (10, vision loss (11, 8 of which accompanied with stroke, sepsis (3, multiple abscess (1 and giant fat necrotic cyst (2. Ten of these complications happened within 10 years. Conclusions: There is no unified measurement method to evaluate fat graft SR until now and no clinical evidence to show better SR according to different donor and recipient cite. Body mass index change between pre- and postoperation may be the bias factor in evaluating fat SR. Fat embolisms of the ophthalmic artery and the middle cerebral artery are the most severe complication of AFG and still lack
Recovery from brain injury is not only determined by the primary injury, but a very important element is the development of secondary complications which have a major role in determining the possibility of the achievement of available maximal functional abilities and the quality of life of the patients and their family after rehabilitation. This is why during medical treatment the prevention of secondary complications is at least as important as the prevention of primary injury. Determination of the most important secondary complications after severe brain injury, and observation of these effects on the rehabilitation process. Retrospective study in the Brain Injury Rehabilitation unit of the National Institute for Medical Rehabilitation in Hungary. 166 patients were treated with brain injury; the mean age of the patients was 33 (8-83) years in 2004. The majority of patients suffered traumatic brain injury in traffic accidents (125/166), while the rest of them through falls or acts of violence. Sixty-four patients were admitted directly from an intensive care unit, 18 from a second hospital ward (traumatology, neurosurgery or neurology) and the rest of the patients were treated in several different units before they were admitted for rehabilitation. The time that has elapsed between injury and rehabilitation admission was 50 days (21-177). At the time of admission 27 patients were in a vegetative state, 38 patients in a minimal conscious state, and 101 patients had already regained consciousness. 83 patients were hemiparetic, 54 presented tetraparesis, and 1 paraparesis, but 28 patients were not paretic. The most frequent complications in patients with severe brain injury at admission in our rehabilitation unit were: contractures (47%), pressure sores (35%), respiratory (14%) and urinary (11%) tract infections, malnutrition (20%). The functional outcome was worse in the cases arriving with secondary complications during the same rehabilitation period. The length of

Malignancy is a secondary cause of sarcopenia, which is associated with impaired cancer treatment outcomes. The aim of this study was to investigate the prevalence of preoperative sarcopenia among elderly gastric cancer patients undergoing gastrectomy and the differences in preoperative dietary intake and postoperative complications between sarcopenic and non-sarcopenic patients. Ninety-nine patients over 65 years of age who underwent gastrectomy for gastric cancer were analyzed. All patients underwent gait and handgrip strength testing, and whole-body skeletal muscle mass was measured using a bioimpedance analysis technique based on the European Working Group on Sarcopenia in Older People (EWGSOP) algorithm for the evaluation of sarcopenia before surgery. Preoperative dietary intake was assessed using a food frequency questionnaire. Of these patients, 21 (21.2 %) were diagnosed with sarcopenia. Sarcopenic patients consumed fewer calories and less protein preoperatively (23.9 vs. 27.8 kcal/kg ideal weight/day and 0.86 vs. 1.04 g/kg ideal weight/day; P = 0.001 and 0.0005, respectively). Although the overall incidence of postoperative complications was similar in the two groups (57.1 % vs. 35.9 %; P = 0.08), the incidence of severe (Clavien-Dindo grade ≥ IIIa) complications was significantly higher in the sarcopenic group than in the non-sarcopenic group (28.6 % vs. 9.0 %; P = 0.029). In the multivariate analysis, sarcopenia alone was identified as a risk factor for severe postoperative complications (odds ratio, 4.76; 95 % confidence interval, 1.03-24.30; P = 0.046). Preoperative sarcopenia as defined by the EWGSOP algorithm is a risk factor for severe postoperative complications in elderly gastric cancer patients undergoing gastrectomy.
Full Text Available BACKGROUND: Preeclampsia is a hypertensive multisystem disorder of pregnancy that complicates up to 10% of pregnancies worldwide and is one of the leading causes of maternal and perinatal morbidity and mortality. AIM: To evaluate maternal complications associated with severe preeclampsia. METHODS: This is a retrospective cross-sectional study conducted in the UHOG “Koço Gliozheni”, in Tirana. Primary outcomes evaluated: maternal death, eclampsia, stroke, HELLP syndrome, and pulmonary edema. Secondary outcomes: renal failure, admission in ICU, caesarean section, placental abruption, and postpartum hemorrhage. Fisher’s exact test and Chi-squared test were used as statistical methods. RESULTS: In women with severe preeclampsia we found higher rates of complications comparing to the group with preeclampsia. Eclampsia (1.5% vs. 7.1%, P < 0.001, HELLP syndrome (2.4% vs. 11.0%; P < 0.001, stroke (0.5% vs 1.9%, P = 0.105 pulmonary edema (0.25% vs. 1.3%, P = 0.0035, renal failure (0.9% vs. 2.6%, P = 0.107, admission in ICU (19.5% vs. 71.4%, P = 0.007, caesarean section rates (55.5% vs. 77%, P = 0.508, placental abruption (4.3% vs. 7.8%, P = 0.103 and severe postpartum hemorrhage (3.2% vs. 3.9%, P = 0.628. CONCLUSION: Severe preeclampsia is associated with high rates of maternal severe morbidity and early diagnosis and timely intervention can prevent life treating complications.

We report the case of a 42-year-old man admitted for a multi-organ failure with a coma, a hemodynamic instability, a respiratory distress syndrome, an acute renal failure and a thrombocytopenia. The blood samples highlighted a milky serum and allowed to diagnose an acute pancreatitis associated with a major dyslipidemia: hypertriglyceridemia 11,800 mg/dL and hypercholesterolemia 1195 mg/dL. The CT-scans do not reveal any cerebral abnormalities but highlighted pancreatic lesions without biliary obstruction. A multi-organ failure complicating a severe acute pancreatitis secondary of a major hypertriglyceridemia was mentioned. Despite the absence of clear guidelines, a session of plasma exchange was started in emergency. Symptomatic treatment with protective ventilation, vasopressors, continuous heparin and insulin was continued. The clinical and biological course was good in parallel of the normalization of lipid abnormalities. The patient was discharged at day 17 with a lipid-lowering therapy. We discuss the various treatments available for the management of acute pancreatitis complicating a severe hypertriglyceridemia and their actual relevance in the absence of clear recommendations.

Laparoscopic sleeve gastrectomy (LSG) is widely adopted but exposes serious complications. A retrospective database analysis was done to study LSG staple line complications in a tertiary referral university center with surgical ICU experienced in treatment of morbid obesity and complications. Twenty-two consecutive patients were referred between January 2004 and February 2012 with postoperative gastric leak or stenosis after LSG. Interventions consisted in the control of intra-abdominal and general sepsis; restoration of staple line continuity or revision of LSG; nutritional support; treatment of associated complications. Main outcome measures concerned success rates of therapeutic strategies, morbidity and mortality rates, LOS, and time to cure. Thirteen patients (59 %) were referred after failure of reoperation (seven fistula repairs were attempted). Three patients received emergency surgery in our center with transorificial intubation and jejunostomy formation. An endoscopic stent was tried in nine patients but failed in 84.6 % of cases within 20 days (1-161). Seven patients (32 %) necessitated total gastrectomy within 217 days (0-1,915 days) for conservative treatment failure. Procedures under general anesthesia were required in 41 % of cases, organ failure was found in 55 % of cases, and central venous device infection in 40 %. Mortality rate was 4.5 % (n = 1). Patients with unfavorable evolution of LSG complications (death or additional gastrectomy) had more previous bariatric procedure (82 % vs. 18 %, p = 0.003). Median time to cure was 310 days (9-546 days). LSG exposes severe complications occurring in patients with benign condition. Endoscopic stents entail high failure rate. Total gastrectomy is required in one third of the cases.

A 46-year-old woman with severe intestinal complication caused by high dose-rate intracavitary irradiation is reported. She received radiation treatment of stage IIb cervical cancer between July 24 and September 26, 1984: a dose of 2400 rad to a point A concurrently with 2000 rad to the parametrium following 4000 rad to the whole pelvis. Eight months later she developed diarrhea and bloody stool. Barium enema study revealed a stenosis at 20 to 25 cm from the anal ring and romanoscopy oozing coagula at the same site. On November 29, 1985 transverse colostomy was performed because of continuing bloody stool and abdominal pain. On January 30, 1986 resection of the ileum and ileostomy were done because of the ileum perforation located 26 cm apart from the ileum end. Some discussion on the causes of this complication are made, suggesting that short length of a tandem and deep location of ovoids influence its cause.

Pregnancy associated with aplastic anemia (AA) is a rare and heterogeneous disorder. We aimed to identify and evaluate the maternal and pregnant outcomes of pregnancy-associated severe AA treated with supportive care. A 25-year retrospective study was conducted at in a single center between 1990 and 2014 with pregnancy associated severe AA. In addition, relevant published cases of antenatally diagnosed pregnancy-associated severe AA after 1990 were identified by PubMed. The main goal was to determine the impact of various risk factors on maternal and fetal outcomes. 15 women with 18 pregnancies were enrolled. With addition of the published reports in literature, a total of 36 cases were included for reference review. Univariate analysis showed that low platelet counts (<2.0 × 10 9 /L), bone marrow hypocellularity (<25%), and late diagnosis during pregnancy were predictors of poor maternal outcomes (P < 0.05). The complication rate of pregnancy outcomes was 53.3%, including preterm delivery, small gestational age (SGA), preterm premature ruptured of membranes (PPROM) and preeclampsia. This study identified the risk factors of mortality and morbidity in pregnant women with severe AA, as well as the obstetrical complications associated with neonatal outcome. Copyright © 2017.

The purpose of this study was to determine if a causal relationship exists between obstetric complications (OCs) severity and linear magnetic resonance (MR) measurements of brain atrophy in patients with schizophrenia. Linear measurements of ventricular enlargement (bifrontal span, Evans ratio, and bicaudate ratio) and hippocampal atrophy (interuncal distance) were completed on MR images obtained in 47 patients with schizophrenia. Regression analysis was used to look at association with OCs severity, assessed by the ''Midwife protocol'' of Parnas and colleagues. The relationship between MR measurements and phenomenologic variables such as age at onset, illness duration, and exposure to antipsychotic medications was explored. The relationship between MR measurements, OCs severity, and symptom presentation was also investigated. OCs severity was significantly associated with MR measurements of ventricular enlargement (bifrontal span, Evans ratio). As the severity of OCs increased, bifrontal span and Evans ratio increased. This effect was independent of age at onset, illness duration, or even antipsychotic treatment. Interestingly, bifrontal span, Evans ratio, and OCs severity score all showed a significant positive correlation with hallucinatory symptomatology. Although confirmatory studies are needed, our findings would support the idea that environmental factors, in this case severe OCs, might partly contribute to ventricular abnormalities in schizophrenia.

The purpose of this study was to determine if a causal relationship exists between obstetric complications (OCs) severity and linear magnetic resonance (MR) measurements of brain atrophy in patients with schizophrenia. Linear measurements of ventricular enlargement (bifrontal span, Evans ratio, and bicaudate ratio) and hippocampal atrophy (interuncal distance) were completed on MR images obtained in 47 patients with schizophrenia. Regression analysis was used to look at association with OCs severity, assessed by the ''Midwife protocol'' of Parnas and colleagues. The relationship between MR measurements and phenomenologic variables such as age at onset, illness duration, and exposure to antipsychotic medications was explored. The relationship between MR measurements, OCs severity, and symptom presentation was also investigated. OCs severity was significantly associated with MR measurements of ventricular enlargement (bifrontal span, Evans ratio). As the severity of OCs increased, bifrontal span and Evans ratio increased. This effect was independent of age at onset, illness duration, or even antipsychotic treatment. Interestingly, bifrontal span, Evans ratio, and OCs severity score all showed a significant positive correlation with hallucinatory symptomatology. Although confirmatory studies are needed, our findings would support the idea that environmental factors, in this case severe OCs, might partly contribute to ventricular abnormalities in schizophrenia.

Patients with cardiovascular diseases are a group of increased risk of acute kidney injury (AKI). Mortality in this group of patients with AKI, especially treated in intensive care units, is very high. The aim of this study was to evaluate the clinical characteristic of patients with AKI complicated severe cardiovascular diseases. Retrospective evaluation of 246 questionnaire of patients with AKI in the course of severe cardiovascular diseases treated in the wards of nephrological profile from the malopolska and podkarpackie voivodships in the years 2000-2011 was performed. The group of patients consisted of 157 men and 89 women, with mean age 67.9 ± 14.8 years. The most common cause of AKI were: acute decompensated heart failure--24 (9.8%), chronic decompensated heart failure--94 (38.2%), cardiac arrest--29 (11.8%), myocardial infarction--48 (19.5%), CABG--12 (4.9%), cardiac valve implantation--14 (5.7), heart transplantation--4 (1.6%) and aortic aneurysm--21 (8.5%). Age distribution of patients with AKI revealed that most numerous group had 71-80 years. The most of patients (95.9%) with AKI were treated with hemodialysis. The mortality rate in the study group was very high (69.5%). Recovery of renal function was observed in 39 (27.3%) of patients. Signs of kidney disease before AKI was noted in 116 (47.2%) of patients. Patients with severe cardiovascular complications and AKI had high mortality rate instead of performed hemodialysis treatment.

Objective: To evaluate the efficacy and safety of emergency transcatheter occlusion of patent ductus arteriosus associated with severe pneumonia in infants. Methods: During the period from Oct. 2011 to May 2012, 12 infants with patent ductus arteriosus complicated by severe pneumonia were admitted to the hospital. The infants had repeated episodes of pneumonia together with heart failure. Emergency transcatheter occlusion of patent ductus arteriosus was carried out in all infants. After the treatment the use of anti-bacterial drugs and cardiac stimulants was kept on. Routine examinations of blood and urine were made 24 hours after the management. Two-dimensional and color Doppler echocardiography, chest radiograph and electrocardiogram were performed at 24 hours, 1, 3, and 6 months after the surgery. The results were analyzed. Results: After emergency transcatheter closure, all patients recovered fully at the time of discharge. No intervention-related major complications occurred during short-term follow-up period. Conclusion: For the treatment of patent ductus arteriosus associated with severe pneumonia in infants, emergency transcatheter occlusion therapy is effective and safe. Optimal surgery time together with proper perioperative management is the key to ensure a successful operation. (authors)

During abdominal surgery, traction of the mesenterium provokes mesenteric traction syndrome, including hypotension, tachycardia, and flushing, along with an increase in plasma prostacyclin (PGI 2 ). We evaluated whether postoperative complications are related to mesenteric traction syndrome during esophagectomy. Flushing, hemodynamic variables, and plasma 6-keto-PGF 1α were recorded during the abdominal part of open ( n = 25) and robotically assisted ( n = 25) esophagectomy. Postoperative complications were also registered, according to the Clavien-Dindo classification. Flushing appeared in 17 (open) and 5 (robotically assisted) surgical cases ( p = 0.001). Mean arterial pressure was stable during both types of surgeries, but infusion of vasopressors during the first hour of open surgery was related to development of widespread (Grade II) flushing ( p = 0.036). For patients who developed flushing, heart rate and plasma 6-keto-PGF 1α also increased ( p = 0.001 and p syndrome manifests more frequently during open than robotically assisted esophagectomy, and postoperative complications appear to be associated with severe mesenteric traction syndrome.

Surgery for pancreatic cancer yields significant morbidity and mortality risks and survival is limited. Therefore, the influence of complications on quality of life (QoL) after pancreatic surgery is important. This study compares QoL in patients with and without severe complications after surgery for pancreatic (pre-)malignancy. This prospective cohort study scored complications after pancreatic surgery according to the Clavien-Dindo system and the definitions of the International Study Group of Pancreatic Surgery. QoL was measured by the RAND36 questionnaire, the European Organization for Research and Treatment of Cancer core questionnaire (QLQ-C30) and the pancreas specific QLQ-PAN26. QoL in patients with severe complications was compared with QoL in patients with no or mild complications over a period of 12 months. Analysis was performed with linear mixed models for repeated measurements. Between March 2012 and July 2016, 137 patients were included. Sixty-eight patients (50%) had at least 1 severe complication. There were no statistically significant and clinically relevant differences between both groups in QoL up to 12 months after surgery. In this study, no differences in QoL between patients with and without severe postoperative complications were encountered during the first 12 months after surgery for pancreatic (pre-)malignancy. http://www.clinicaltrials.gov Identifier: NCT02175992.

Full Text Available The elevated glycation of macromolecules by the reactive dicarbonyl and α-oxoaldehyde methylglyoxal (MG has been associated with diabetes and its complications. We have identified a rare flavone, fisetin, which increases the level and activity of glyoxalase 1, the enzyme required for the removal of MG, as well as the synthesis of its essential co-factor, glutathione. It is shown that fisetin reduces two major complications of diabetes in Akita mice, a model of type 1 diabetes. Although fisetin had no effect on the elevation of blood sugar, it reduced kidney hypertrophy and albuminuria and maintained normal levels of locomotion in the open field test. This correlated with a reduction in proteins glycated by MG in the blood, kidney and brain of fisetin-treated animals along with an increase in glyoxalase 1 enzyme activity and an elevation in the expression of the rate-limiting enzyme for the synthesis of glutathione, a co-factor for glyoxalase 1. The expression of the receptor for advanced glycation end products (RAGE, serum amyloid A and serum C-reactive protein, markers of protein oxidation, glycation and inflammation, were also increased in diabetic Akita mice and reduced by fisetin. It is concluded that fisetin lowers the elevation of MG-protein glycation that is associated with diabetes and ameliorates multiple complications of the disease. Therefore, fisetin or a synthetic derivative may have potential therapeutic use for the treatment of diabetic complications.

Objective: To assess the clinical application of 131 I and artificial liver support system (ALSS) in the treatment of hyperthyroidism complicated with severe hepatitis. Methods: Forty-three hyperthyroidism patients complicated with severe hepatitis were divided into two groups: 18 cases treated with anti-thyroid drugs (ATD) as group A, and 25 cases with 131 I therapy as group B, the group B was further divided into: 12 cases were treated without ALSS as group B1, while 13 cases with ALSS as in group B2. The cure and improved rates were compared between group A and B, and the cure rates were compared between group B1 and B2, respectively. Moreover, the changes of serum level of thyroid and liver function indexes before and 1 week after each ALSS therapy were observed. Results: The cure and improved rate of group B (96.0%) was significantly higher than that of group A (61.1%), and the cure rate of group B2 (84.6%) was significantly higher than that of group B1 (33.3%, P 3 , FT 4 , total bilirubin (TBIL), direct bilirubin (DBIL), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) improved obviously after ALSS therapy (P 131 I is more effective. Besides, ALSS is safe, and it can improve cure rate. (authors)
The World Health Organization has elaborated a maternal and neonatal near-miss reporting, audit and feedback system designed to improve the quality of care during and after childbirth. As part of a four-hospital comparative study in the Middle East, this article discusses the experiences of mothers whose newborns suffered from severe complications at birth in the Rafik Hariri University Hospital, the only public hospital in Beirut. Based on in-depth home interviews several weeks after childbirth, it aims to explore the experience of neonatal near-miss events through the mothers' birth narratives. The central concerns of these vulnerable and marginalised women regarded access to neonatal care, and how to negotiate hospital bureaucracy and debt. It argues that financial and bureaucratic aspects of the near-miss event should be part of the audit system and policy-making, alongside medical issues, in the quest for equitable access to and management of quality perinatal care.
Full Text Available RationaleEffective immunomodulatory therapies for children with life-threatening “cytokine storm” triggered by acute influenza infection are lacking. Understanding the immune profiles of children progressing to severe lung injury and/or septic shock could provide insight into pathogenesis.ObjectivesTo compare the endotracheal and serum cytokine profiles of children with influenza-related critical illness and to identify their associations with severe influenza-associated complications.MethodsChildren with influenza-related critical illness were enrolled across 32 hospitals in development (N = 171 and validation (N = 73 cohorts (December 2008 through May 2016. Concentrations of 42 cytokines were measured in serum and endotracheal samples and clustered into modules of covarying cytokines. Relative concentrations of cytokines and cytokine modules were tested for associations with acute lung injury (ALI, shock requiring vasopressors, and death/ECMO.Measurements and main resultsModules of covarying cytokines were more significantly associated with disease severity than individual cytokines. In the development cohort, increased levels of a serum module containing IL6, IL8, IL10, IP10, GCSF, MCP1, and MIP1α [shock odds ratio (OR = 3.37, family-wise error rate (FWER p < 10−4], and decreased levels of a module containing EGF, FGF2, SCD40L, and PAI-1 (shock OR = 0.43, FWER p = 0.002, were both associated with ALI, shock, and death-ECMO independent of age and bacterial coinfection. Both of these associations were confirmed in the validation cohort. Endotracheal and serum cytokine associations differed markedly and were differentially associated with clinical outcomes.ConclusionWe identified strong positive and negative associations of cytokine modules with the most severe influenza-related complications in children, providing new insights into the pathogenesis of influenza-related critical illness in children.

Although, Plasmodium vivax is a rare parasite in most parts of Africa, it has significant public health importance in Ethiopia. In some parts of the country, it is responsible for majority of malaria associated morbidity. Recently severe life threatening malaria syndromes, frequently associated to P. falciparum, has been reported from P. vivax mono-infections. This prompted designing of the current study to assess prevalence of severe malaria complications related to P. vivax malaria in Ethiopia. The study was conducted in two study sites, namely Kersa and Halaba Kulito districts, located in southwest and southern parts of Ethiopia, respectively. Children, aged ≤ 10 years, who visited the two health centers during the study period, were recruited to the study. Clinical and demographic characteristics such as age, sex, temperature, diarrhea, persistent vomiting, confusion, respiratory distress, hepatomegaly, splenomegaly, hemoglobinuria, and epitaxis were assessed for a total of 139 children diagnosed to have P. vivax mono-infection. Parasitological data were collected following standard procedures. Hemoglobin and glucose level were measured using portable hemocue instrument. Median age of children was 4.25 ± 2.95 years. Geometric mean parasite count and mean hemoglobin level were 4254.89 parasite/μl and 11.55 g/dl, respectively. Higher prevalence rate of malaria and severe malaria complications were observed among children enrolled in Halaba district (P infection (OR = 1.9, 95% CI, 1.08 to 3.34), while female had higher risk to anemia (OR = 1.91, 95% CI, 1.08 - 3.34). The observed number of anemic children was 43%, of which most of them were found in age range from 0-3 years. Furthermore, P. vivax malaria was a risk factor for incidence of anemia (P lower than those reported from other countries. However, incidence of severe malaria complications in one of the sites, Halaba district, where there is highest treatment failure to first line drug, could have

Full Text Available This study investigates the long term economic impact of severe obstetric complications for women and their children in Burkina Faso, focusing on measures of food security, expenditures and related quality of life measures. It uses a hospital based cohort, first visited in 2004/2005 and followed up four years later. This cohort of 1014 women consisted of two main groups of comparison: 677 women who had an uncomplicated delivery and 337 women who experienced a severe obstetric complication which would have almost certainly caused death had they not received hospital care (labelled a "near miss" event. To analyze the impact of such near miss events as well as the possible interaction with the pregnancy outcome, we compared household and individual level indicators between women without a near miss event and women with a near miss event who either had a live birth, a perinatal death or an early pregnancy loss. We used propensity score matching to remove initial selection bias. Although we found limited effects for the whole group of near miss women, the results indicated negative impacts: a for near miss women with a live birth, on child development and education, on relatively expensive food consumption and on women's quality of life; b for near miss women with perinatal death, on relatively expensive foods consumption and children's education and c for near miss women who had an early pregnancy loss, on overall food security. Our results showed that severe obstetric complications have long lasting consequences for different groups of women and their children and highlighted the need for carefully targeted interventions.

Some of the limitations and complications associated with hair and nail analysis are discussed. Data obtained from an occupational study demonstrated the potential for misinterpreting hair or nail analysis data either through describing results averaged over a group by arithmetic instead of geometric means or through not accounting for the age range of subjects in groups to be compared. Examples that arose from the study indicated that differences between hair from the same subjects grown at different times can both complicate and assist in interpreting hair analysis results. In an investigation into the addition and removal of metallic powders, it was found that both hair and nail can directly incorporate elements through contact with dust. (author)

To evaluate the efficacy and safety of cyanoacrylate glue embolization in the treatment of severe arterioportal shunt (APS) presenting with hepatofugal portal venous flow in hepatocellular carcinoma (HCC) patients. Between July 2000 and January 2010, 27 HCC patients with severe APS presenting with hepatofugal portal venous flow underwent transarterial angiography and treatment. Among them, four patients were excluded from the study. Twelve patients underwent transarterial chemoperfusion and embolization of APS with cyanoacrylate glue between January 2006 and January 2010 (Emb group), and the other 11 patients undergoing only transarterial chemoperfusion without embolization of APS between July 2000 and December 2005 served as a control group (non-Emb group). The change of APS, survival rates, and procedure related complications were analyzed. In the Emb group, APS was improved in all of the 12 patients after initial glue embolization; long-term APS improvement with hepatopetal portal flow was achieved in 80 % (8 of 10) patients who underwent follow-up angiography. Survival rates in the Emb group were 67 % at 6 months, 33 % at 1 year, and 8 % at 2 years, whereas those in the non-Emb group were 0 % at 6 months (P < 0.05). Median survival time in the Emb group was 275 days, which was longer than that of 107 days in the non-Emb group (P = 0.001). There were no major complications in both groups. The preliminary experience suggests that glue embolization may be an effective and safe therapy in the management of severe APS accompanied by HCC and also improve patient survival.
Full Text Available Introduction. Incidence of gastroschisis (GS complicated by intestinal atresia is 4.5–12.6% of cases. 80% of this obstructions are observed in jejunoileal segment. Association of GS with intestinal atresia (GIA is usually diagnosed well, but at birth, diagnosis of atresia is often controversial. There is misdiagnosis of atresia during the initial surgery in about 12% of cases. The ideal treatment model of GIA had not already been set. Different surgical approaches were described in literature: abdominal closure modalities, terms of intestinal anastomoses creation and intestinal stomas formation remain outstanding issues. the severity of congenital defects may vary thus the tactics and strategy of surgical management as well as the ability to create primary intestinal anastomosis should be considered individually. Clinical case. GS with severe viscero-abdominal disproportion (VAD in fetus was diagnosed prenatally by ultrasonography (US at 21 week of gestation. Prenatal US follow-up monitoring and examinations were conducted. The presence of concomitant intestinal obstruction was suspected at 35 week of gestation. Regarding diagnosed malformations, according to developed in our clinic "First Minutes Surgery" tactics, operation was performed in 15 minutes after birth. During the initial surgery intestinal obstruction was not confirmed. Staged surgical management of GS was conducted. Intestinal obstruction was diagnosed and confirmed by radiography only after 21 days of age, after increasing of oral intakes volume to 15.0 ml. Jejunal web was found on surgery. Following web removal diamond-shaped anastomosis was created. During post-op period the recurrence of intestinal obstruction was not observed, full enteral nutrition was reached. The good outcome after exhibited surgical management was achieved. Conclusions. The proposed strategy and tactics of surgical management found to be effective and can be applied in the case of GS with severe VAD
Full Text Available Absent pulmonary valve syndrome (APVS is a rare congenital heart disease with severe pulmonary insufficiency, characterized with aneurysmal dilation in the pulmonary artery and one or both of its branches. We presented a rare case with APVS and literature review in this letter. Prenatal USG examination of the fetus at the 26th week of gestation revealed severe polyhydramnios, dilatation at right ventricle, and abnormal appearance of the heart. At the 31st gestational week, the baby was born with cesarean section. The newborn had right heart failure but had no hydrops fetalis. Therefore, severe respiratory distress observed in the infant has been associated with pulmonary complications. The infant, who had respiratory acidosis according to blood gas analysis, was intubated and attached to mechanical ventilator. Despite progressively increased respiratory support and other interventions, the infant died on the 3rd day of admission. Compression against bronchial tree and esophagus due to dilated pulmonary artery and its branches may inevitably lead to bronchomalacia and polyhydramnios. In conclusion, presence of polyhydramnios and the possibility of severe bronchomalacia should be kept in mind; and due to the risk of early neonatal mortality, delivery should be performed in a center where pediatric heart surgery is available.

To explore an method and the effectiveness of surgical treatment of thoracic and lumbar tuberculosis complicated with severe kyphotic deformity (Cobb angle ≥ 55°) and paraplegia. Between January 2009 and January 2013, 13 cases of thoracic and lumbar tuberculosis complicated with severe kyphotic deformity and paraplegia were treated by one-stage posterior vertebral column resection (PVCR), debridement, bone grafting, and instrumentation fixation. Of 13 patients, 7 were male and 6 were female with an average age of 23.5 years (range, 14-49 years). The disease duration was 13-38 months (mean, 19 months). The Cobb angle of kyphosis was (65.23 ± 7.95)°. The visual analogue scale score (VAS) was 7.38 ± 0.31. In 13 patients with incomplete paraplegia, 1 case was classified as Frankel grade B, 7 cases as grade C, and 5 cases as grade D. The lesion involved 2 vertebrae bodies in 7 cases (T8, 9 in 1 case, T11, 12 in 2 cases, and T12, L1 in 4 cases), 3 vertebrae bodies in 4 cases (T10-12 in 2 cases, T9-11 in 1 case, and T11-L1 in 1 case), and 4 vertebrae bodies in 2 cases (T4-7 in 1 case and T6-9 in 1 case). Imaging examination showed paravertebral abscess in 10 cases. Healing of incision by first intention was obtained in all patients. The neurological injury and pulmonary infection occurred in 3 cases and 2 cases respectively, which were cured after symptomatic treatment. Thirteen patients were followed up 12-48 months (mean, 17 months). The erythrocyte sedimentation rate restored to normal level in all cases at 3-7 months after operation. All the patients achieved bony fusion at 10-20 months (mean, 14 months) after operation. No fixation loosening, displacement, or fracture occurred during follow-up. Common toxic symptom of tuberculosis disappeared, and there was no recurrence of local tuberculosis. The Cobb angle of kyphosis was corrected to (22.38 ± 1.76)° at 1 week and (22.15 ± 1.83)° at last follow-up, showing significant difference when compared with

We report four cases of acute pulmonary edema that occurred during treatment by intravenous tocolysis using nicardipine in pregnancy patients with no previous heart problems. Clinical severity justified hospitalization in intensive care unit (ICU) each time. Acute dyspnea has begun at an average of 63 hours after initiation of treatment. For all patients, the first diagnosis suspected was pulmonary embolism. The patients' condition improved rapidly with appropriate diuretic treatment and by modifying the tocolysis. The use of intravenous nicardipine is widely used for tocolysis in France even if its prescription does not have a marketing authorization. The pathophysiological mechanisms of this complication remain unclear. The main reported risk factors are spontaneous preterm labor, multiple pregnancy, concomitant obstetrical disease, association with beta-agonists, and fetal lung maturation corticotherapy. A better knowledge of this rare but serious adverse event should improve the management of patients. Nifedipine or atosiban, the efficiency of which tocolysis was also studied, could be an alternative.

Aplastic anaemia is characterized by severe compromise of haematopoiesis and hypocellular bone marrow. Haemorrhagic episodes in patients with aplastic anemia occur usually secondary to thrombocytopenia and require frequent support with platelet concentrates and other blood products. Infection with dengue virus (particularly dengue sero type-2 of South Asian genotype) is associated with dengue haemorrhagic fever. Dengue infection further worsens the disease process in patients with aplastic anaemia due to uncontrolled haemorrhagic diathesis and major organ failure, which may prove fatal in these already immunocompromised patients, if not treated in time. Recent epidemics of dengue haemorrhagic fever has not only affected the southern region of our country but also spread to other areas of the country. With this background, we report a case of aplastic anaemia complicated by dengue haemorrhagic fever who achieved successful engraftment after allogeneic stem cell transplantation from sibling brother and is having normal healthy post transplant life.

To investigate the clinical benefit of internal limiting membrane (ILM) peeling as a surgical adjunct in the repair of primary retinal detachment (RD) complicated by grade B proliferative vitreoretinopathy (PVR). Retrospective, interventional, comparative case series. SETTING: Institutional. 75 consecutive patients who underwent vitrectomy for primary macula off RD complicated by grade B PVR. Patients were divided into an ILM peeling (group P) and a no ILM peeling (group NP). Anatomical success rate, best-corrected visual acuity, and spectral-domain optical coherence tomography (SD-OCT) characteristics were collected at 1 and 6 months. In all, 37 eyes with ILM peeling were included in group P and 38 eyes without ILM peeling were included in group NP. The anatomical success rate after single surgery was higher in group P (89%) than in group NP (66%, p=0.03). Mean final visual acuity was 0.41 ±0.40 logMAR in group P versus 0.43 ±0.22 logMAR in group NP (p=0.82). We found no epiretinal membrane (ERM) formation in group P, whereas five cases of ERM (20%) were detected in group NP (p=0.012). The two groups did not differ in terms of cystoid macular edema occurrence, macular thickness, or photoreceptor damage. ILM peeling during vitrectomy in macula off RD complicated by grade B PVR reduces the need for a second surgery for re-detachment or macular pucker. Copyright © 2018. Published by Elsevier Inc.

The aim of this case study was to report a potentially convenient approach instead of a conventional orthodontic procedure for correcting severe rotation of anterior tooth of an 11-year-old Indian boy, with a mixed dentition class I malocclusion. The child reported seeking treatment for severely rotated upper right central incisor with mesiodens and a single tooth crossbite. The supernumerary tooth was first extracted and bondable buttons were placed on the rotated tooth, an appliance composed of a removable plate with Adam's clasp with distal extension and a loop for engagement of elastics was delivered. Circumferential supracrestal fibrotomy was performed on the corrected derotated tooth. Then, Hawley's appliance with a z-spring and posterior bite plane was fabricated and placed for correction of crossbite. Thus, this removable appliance can be a simplified and a cost-effective treatment alternative for derotation of anterior tooth, especially during the mixed dentition period.

Objective: To study the radiological features of severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease so as to make early diagnosis and treatment. We also intend to find the mechanism of these complications. Methods: A total of 9 pediatric cases with severe respiratory complications during cardiac catheterizations were included in the study. The clinical manifestations, radiological features, and corresponding treatments were reviewed. Results: Most of the cases had severe hypoxia, with 6 cases presenting with bradycardia. Opacification of two lung fields was found in 7 cases, pulmonary edema in 1 case, and atelectasis of the upper right lung in 1 case. With intubation, oxygen inhalation and administration of certain drugs, all cases were saved except 1 case with pulmonary edema. Conclusion: Severe respiratory complications during cardiac catheterizations on pediatric congenital heart disease are emergent and critical, and they often presented with various manifestations. Early diagnosis and correct treatment are the key to successful salvage. (authors)
Full Text Available Abstract We report a 14-year-old girl with juvenile dermatomyositis (JDM complicated by severe inflammatory calcinosis successfully treated with thalidomide. She was diagnosed as JDM when she was 4 years old after a few months of increasing lethargy, muscle pain, muscle weakness, and rash. During three months, clinical manifestations and abnormal laboratory findings were effectively treated with oral prednisolone. However, calcinosis was recognized 18 months after disease onset. Generalized calcinosis rapidly progressed with high fever, multiple skin/subcutaneous inflammatory lesions, and increased level of CRP. Fifty mg/day (1.3 mg/kg day of oral thalidomide was given for the first four weeks, and then the dose was increased to 75 mg/day. Clinical manifestations subsided, and inflammatory markers had clearly improved. Frequent high fever and local severe pain with calcinosis were suppressed. The levels of FDP-E, IgG, and tryglyceride, which were all elevated before the thalidomide treatment, were gradually returned to the normal range. Over the 18 months of observation up to the present, she has had no inflammatory calcinosis, or needed any hospitalization, although established calcium deposits still remain. Her condition became painless, less extensive and less inflammatory with the CRP level below 3.08 mg/dL. Recent examination by whole-body 18F-FDG-PET-CT over the 15 months of thalidomide treatment demonstrated fewer hot spots around the subcutaneous calcified lesions.

In Morocco, medical care for women with severe obstetric complications (near-miss cases) ends at discharge from the hospital. Little information exists regarding what happens after returning home. The aim of the study was to assess the physical and mental health consequences of near-miss events on Moroccan women 8 months after childbirth. A prospective cohort study of 76 near-miss women was conducted in three hospitals. For every case, we recruited at least two women from the same hospital who had uncomplicated deliveries (n = 169). We used a mixed-methods approach. For the quantitative part, we analysed sociodemographic characteristics collected via a questionnaire and medical complications extracted from the medical records during a medical consultation at 8 months post-partum. Forty in-depth interviews were also conducted with 20 near-miss cases and 20 women with uncomplicated deliveries. The near-miss women were poorer and less educated than those who had uncomplicated deliveries. The proportion of physical consequences (serious illness) was higher among near-miss cases (22%) than uncomplicated deliveries (6%, P = 0.001). The risk of depression was significantly higher among near-miss cases with perinatal death (OR = 7.16; [95% CI: 2.85-17.98]) than among those who had an uncomplicated delivery. Interviews revealed that the economic burden of near-miss care contributed to social problems among the women and their households. A near-miss event has consequences that go beyond the first days after delivery. Developing new mechanisms for maternal and newborn health follow-up is essential and should address the mother's physical and mental health problems and involve husbands and family members. © 2015 The Authors.

Purpose: The aim of our study was to update the rate of severe complications following CT-guided needle biopsy in Japan via a mailed survey. Materials and methods: Postal questionnaires regarding CT-guided needle biopsy were sent out to multiple hospitals in Japan. The questions regarded: the total number and duration of CT-guided lung biopsies performed at each hospital, and the complication rates and numbers of pneumothorax, hemothorax, air embolism, tumor seeding, tension pneumothorax and other rare complications. Each severe complication was followed with additional questions. Results: Data from 9783 biopsies was collected from 124 centers. Pneumothorax was the most common complication, and occurred in 2412 (35%) of 6881 cases. A total of 39 (35%) hospitals reported 74 (0.75%) cases with severe complications. There were six cases (0.061%) with air embolism, six cases (0.061%) with tumor seeding at the site of the biopsy route, 10 cases (0.10%) with tension pneumothorax, six cases (0.061%) with severe pulmonary hemorrhage or hemoptysis, nine cases (0.092%) with hemothorax, and 27 cases (0.26%) with others, including heart arrest, shock, and respiratory arrest. From a total of 62 patients with severe complications, 54 patients (0.55%) recovered without sequela, however one patient (0.01%) recovered with hemiplegia due to cerebral infarction, and the remaining seven patients (0.07%) died. Conclusions: This is the first national study documenting severe complications with respect to CT-guided needle biopsy in Japan. The complication rate in Japan is comparable to internationally published figures. We believe this data will improve both clinicians as well as patients understanding of the risk versus benefit of CT-guided needle biopsy, resulting better decisions
Full Text Available Background Bifrontal contusion is a common clinical brain injury. In the early stage, it is often mild, but it progresses rapidly and frequently worsens suddenly. This condition can become life threatening and therefore requires surgery. Conventional decompression craniectomy is the commonly used treatment method. In this study, the effect of ICP monitored stepwise intracranial decompression surgery on the prognosis of patients with acute severe bifrontal contusion was investigated. Method A total of 136 patients with severe bifrontal contusion combined with deteriorated intracranial hypertension admitted from March 2001 to March 2014 in our hospital were selected and randomly divided into two groups, i.e., a conventional decompression group and an intracranial pressure (ICP monitored stepwise intracranial decompression group (68 patients each, to conduct a retrospective study. The incidence rates of acute intraoperative encephalocele, delayed hematomas, and postoperative cerebral infarctions and the Glasgow outcome scores (GOSs 6 months after the surgery were compared between the two groups.Results (1 The incidence rates of acute encephalocele and contralateral delayed epidural hematoma in the stepwise decompression surgery group were significantly lower than those in the conventional decompression group; the differences were statistically significant (P < 0.05; (2 6 months after the surgery, the incidence of vegetative state and mortality in the stepwise decompression group were significantly lower than those in the conventional decompression group (P < 0.05; the rate of favorable prognosis in the stepwise decompression group was also significantly higher than that in the conventional decompression group (P < 0.05.Conclusions The ICP monitored stepwise intracranial decompression technique reduced the perioperative complications of traumatic brain injury through the gradual release of intracranial pressure and was beneficial to the prognosis of

It was complicated with acute respiratory insufficient (ARI. The most modified subpleural areas were selected from every lobe of the lungs for pathological studies. Prepared histological sections were stained by means of hemotoxylin and eosin and by Van Giеson for light microscopy. The results of the investigation have shown absence of the significant difference of pathological changes in the lungs of patients who died from ARI because of severe brain injury and traumatic intracranial hemorrhage. Pathognomic pathological changes in the lungs as a result of acute lung injury syndrome (ALIS were found in deceased patients on the third day since the SCII (n=8. There was a significant bilateral interstitial edema and mild alveolar edema with the presence of red and blood cells in the alveoli, vascular plethora of the septum interalveolar and stasis of blood in the capillaries, the slight pericapillary leukocyte infiltration, subpleural hemorrhage and laminar pulmonary atelectasis. In deceased patients on 4-6 days after SCII that was complicated with ARI (n=14, morphological changes had been detected in the lungs. It was pathognomic for acute respiratory distress syndrome (ARDS with local pneumonic to be layered. A significant interstitial pulmonary edema was observed in the respiratory part of the lungs. The edema has spread from the walls of the alveoli into the interstitial spaces of the bronchioles and blood vessels, and also less marked serous-hemorrhagic alveolar edema with presence of the fibrin in the alveoli and macrophages. The ways of intrapleural lymphatic drainage were dilatated. Histopathological changes in the lungs of those who died on the 7-15th days after severe closed craniocerebral injury with ARI to be complicated (n=12 have been indicative of two
A case of decisive material degeneration of an esophageal Celestin tube is described: a 50-year-old man with adenocarcinoma of the distal esophagus received a Celestin tube for palliative endoscopic treatment and 8 months later presented with suddenly occurring complete dysphagia. Dissolution of the latex layer in the proximal as well as the distal part of the tube had caused self-disintegration of the Celestin tube and had liberated the monofilament nylon coil which completely obstructed the lumen of the tube. Endoscopic tube removal was only possible by careful attachment of a balloon catheter and peroral extraction after insufflation with contrast medium up to 5 atm. A Medline-based review of the literature revealed different but predominantly severe complications (perforation, hemorrhage, obstruction, and peritonitis) based on material fatigue of the latex layer in esophageal Celestin tubes. At least 6 months after placement of a Celestin tube, regular fluoroscopic controls should be performed to detect early disintegration of the tube. Indication for the placement of Celestin tubes in patients with benign esophageal strictures and longer life expectancy should be assessed very critically.

We report a case of cervical pyogenic spondylitis complicated by epidural abscess with quadriplegia during treatment of severe burns. The patient was a 49-year-old man with 3rd-degree burns to 20% of his body, involving the lower extremities. We performed escharectomy of the 3rd-degree necrosis on days 7 and 16, followed by the first skin graft on day 23. Pseudomonas aeruginosa was detected in the postoperative graft wound culture. On day 23 after the skin graft, he became febrile and began to experience cervical pain and muscle weakness of the extremities. By day 24, quadriplegia had developed. A cervical vertebral magnetic resonance imaging (MRI) scan showed pyogenic spondylitis with an epidural abscess, which was causing the quadriplegia. We treated the patient by performing curettage of the pyogenic lesion and anterior fixation of the cervical vertebral bodies. The fact that P. aeruginosa was detected in the pyogenic focus culture indicated that burn wound sepsis was responsible for the infection. This case reinforces that acting on a strong suspicion helps to establish a diagnosis and initiate appropriate treatment early.

"Complicated" subthreshold depression (CsD) includes at least one of six pathosuggestive "complicated" symptoms: >6 months duration, marked role impairment, sense of worthlessness, suicidal ideation, psychotic ideation, and psychomotor retardation. "Uncomplicated" subthreshold depression (UsD) has no complicated features. Whereas studies show that complicated (CMDD) versus uncomplicated (UMDD) major depression differ substantially in severity and prognosis, UsD and CsD severity has not been previously compared. This study evaluates UsD and CsD pathology validator levels and examines whether the complicated/uncomplicated distinction offers incremental concurrent validity over the standard number-of-symptoms dimension as a depression severity measure. Using nationally representative community data from the National Comorbidity Survey, seven depression lifetime history subgroups were identified: one MDD screener symptom (n=1432); UsD (n=430); CsD (n=611); UMDD (n=182); and CMDD with 5-6 symptoms (n=518), 7 symptoms (n=217), and 8-9 symptoms (n=291). Severity was evaluated using five concurrent pathology validators: suicide attempt, interference with life, help seeking, hospitalization, and generalized anxiety disorder. CsD validator levels are substantially higher than both UsD and UMDD levels, and similar to mild CMDD, disconfirming the "monotonicity thesis" that severity increase with symptom number. Complicated/uncomplicated status predicts severity, and when complicatedness is controlled, number of symptoms no longer predicts validator levels. Diagnoses were based on respondents' fallible retrospective symptom reports during a lay-administered structured interview, which may not yield diagnoses comparable to clinicians' assessments. CsD is more severe than UsD and comparable to mild MDD. Complicated status more validly indicates depression severity than the standard number-of-symptoms measure. Copyright © 2017 Elsevier B.V.

Full Text Available Background: The epidemic growth of morbid obesity has led to an increase in the number of bariatric interventions. During the distribution process of bariatric surgical interventions, the risk for severe nutritious complications such as bariatric beriberi can rise. Methods: By means of systematic literature review, epidemiological data, clinical characteristics and diagnostic as well as therapeutic recommendations for bariatric beriberi were elicited. Databases and registries such as PubMed, Cochrane and Ovid were searched for a defined time period with the key words ‘lack of thiamine' / ‘Wernicke-Korsakoff syndrome' / ‘encephalopathy' after bariatric surgical interventions. Results: Up to December 2013, overall 255 patients had been found as published cases, indicating that the risk for the postoperative occurrence of thiamine deficiency and Wernicke-Korsakoff syndrome is increased in women. In addition, the risk correlates with patient's age. The majority of patients developed symptoms of a dry beriberi with peripheral neuritis, ataxia and paraplegia, indicating an advanced stage of disease approximately 4-12 weeks postoperatively. Laboratory analysis in case of a suspicious clinical finding is the appropriate diagnostics. As treatment, prompt initiation of parenteral thiamine substitution under clinical monitoring is required. Conclusion: Bariatric beriberi can occur within the first 1-3 postoperative months. To minimize the risk of severe consequences, immediate substitution of thiamine in clinical suspicion or prolonged parenteral nutrition is necessary. A delayed diagnosis or missing the correct diagnosis can lead to irreversible damages of the CNS with coma and fatal outcome. Knowledge on the subject, including development of thiamine deficiency, symptomatology and emergency treatment, are considered essential for bariatric surgeons but also for further medical disciplines involved in treatment.

Full Text Available BACKGROUND: Little is known about risk factors for severe outcomes in patients infected with H5N1 and no systematic review has been conducted. Understanding risk factors is an important step for prioritizing prophylaxis or treatment in the event of a pandemic. OBJECTIVES: To systematically evaluate risk factors for severe outcomes in patients with avian influenza H5N1 infection. DATA SOURCES: MEDLINE, EMBASE, CINAHL, GlobalHealth, and CENTRAL through March 2011. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Observational studies of any design published in English, French, Spanish, German or Korean that reported on risk factor-outcome combinations of interest in participants with confirmed H5N1 infections. Outcomes considered included death, ventilator support, hospital and ICU admission, pneumonia, and composite outcomes. STUDY APPRAISAL: Risk of bias was assessed using the Newcastle-Ottawa scale (NOS. RESULTS: We identified 20 studies reporting on 999 patients infected with H5N1. The majority of studies (n = 14, 70% were at intermediate risk of bias, i.e. 4-6 points on the NOS. Females were at increased risk of death (OR 1.75, 95% CI 1.27-2.44, while young age, in particular <5 years of age (OR 0.44, 95% CI 0.25-0.79 for death, was protective. Data on traditional risk factors was scarce and requires further studies. Another major limitation in the published literature was lack of adjustment for confounders. INTERPRETATION: Females were at increased risk for complications following H5N1 infection while young age protected against severe outcomes. Research on traditional risk factors was limited and is required.

Serotonin syndrome (SS) is an underrecognized and potentially fatal disorder that occurs secondary to combinational use or overdose of a single serotonergic medication. The presentation may be complicated by hepatic encephalopathy in cirrhotic patients, which may also affect metabolism of these serotonergic agents. The authors report a rare case of severe SS complicated by hepatic encephalopathy secondary to cirrhosis in a 52-year-old woman after an increase in her home dosage of fluoxetine and addition of other psychiatric medications.

To determine demographic and clinical features of patients with Acanthamoeba keratitis (AK) that are independent risk factors both for bad outcomes and for severe inflammatory complications (SIC). A retrospective audit of medical records of AK cases at Moorfields Eye Hospital from July 2000 to April 2012, including 12 earlier surgical cases. Cases with a bad outcome were defined as those having one or more of the following: corneal perforation, keratoplasty, other surgery (except biopsy), duration of antiamoebic therapy (AAT) ≥10.5 months (the 75th percentile of the whole cohort) and final visual acuity ≤20/80. SICs were defined as having scleritis and/or a stromal ring infiltrate. Multivariable analysis was used to identify independent risk factors for both bad outcomes and SICs. Records of 194 eyes (194 patients) were included, having bad outcomes in 93 (48%). Bad outcomes were associated with the presence of SIC, aged >34 years, corticosteroids used before giving AAT and symptom duration >37 days before AAT. The development of SIC was independently associated with aged >34 years, corticosteroids used before giving AAT and herpes simplex virus (HSV) keratitis treatment before AAT. The prompt diagnosis of AK, avoidance of a misdiagnosis of HSV keratitis and corticosteroid use before the exclusion of AK as a potential cause of keratitis are essential to the provision of a good outcome for patients and for the avoidance of SIC. Older age is an unmodifiable risk factor that may reflect differences in the immune response to AK in this patient subset. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The most feared bleeding complication in fetal and neonatal alloimmune thrombocytopenia (FNAIT) is an intracranial hemorrhage (ICH). However, FNAIT may also lead to other severe bleeding problems. The aim was to analyze this spectrum and evaluate the occurrence of severe hemorrhages other than ICH in fetuses or neonates with FNAIT. A retrospective chart analysis of cases of FNAIT presenting with severe bleeding complications other than ICH at our institution from 1990 to 2015 was conducted. Additionally, a review of the literature was performed to identify case reports and case series on FNAIT presenting with extracranial hemorrhage. Of 25 fetuses or neonates with severe bleeding due to FNAIT, three had isolated severe internal organ hemorrhage other than ICH, two pulmonary hemorrhages and one gastrointestinal hemorrhage. Two of these three neonates died due to this bleeding. Eighteen cases of extracranial bleeding complications as a first presentation of FNAIT were found in the literature, including ocular, gastrointestinal, spinal cord, pulmonary, renal, subgaleal, and genitourinary hemorrhages. Bleeding complications other than ICH may be more extensive, and the presentation of FNAIT may have a greater spectrum than previously described. A high index of suspicion on the possible diagnosis of FNAIT with any bleeding complication in a fetus or neonate may enable adequate diagnostics, adequate treatment, and appropriate follow-up in future pregnancies, as is especially relevant for FNAIT. © 2016 AABB.

Prior research has provided inconsistent data regarding the risk factors associated with complications from arterial cannulation. The goal of this study was to clearly define the incidence and risks factors associated with arterial cannulation complications. After obtaining institutional review board approval, all patients requiring arterial line placement with documentation were included in this retrospective study between January 1, 2006, and December 31, 2012. Leveraging two robust data warehouses, the Perioperative DataMart and the Mayo Clinic Life Silences System, the authors cross-matched arterial line cannulation with a documented vascular consult, neurologic consult, infection, or return to surgery within 30 days in order to identify the initial patient population. A total of 62,626 arterial lines were placed in 57,787 patients, and 90.1% of the catheters placed were 20-gauge catheters. The radial artery was cannulated in 94.5% of patients. A total of 21 patients were identified as having experienced vascular complications or nerve injuries, resulting in a complication rate of 3.4 per 10,000 (95% CI, 2.1 to 5.1). Cardiac surgery had the largest number of catheters placed (n = 15,419) with 12 complications (complication rate = 7.8 per 10,000; 95% CI, 4.0 to 13.6). The rate of complications differed significantly (P < 0.001) across the three most common catheter sizes (2.7 per 10,000 [95% CI, 1.5 to 4.4] for 20 gauge, 17.2 per 10,000 [95% CI, 4.7 to 43.9] for 18 gauge, and 9.4 per 10,000 [95% CI, 1.1 to 34.1] for 5 French). In a large retrospective study, the authors document a very low rate of complications with arterial line placement.

In the present study, the relations of various aspects of working memory to various aspects of language problems in a clinical sample of 97 Dutch speaking 5-year-old children with severe language problems were studied. The working memory and language abilities of the children were examined using an extensive battery of tests. Working memory was operationalized according to the model of Baddeley. Confirmative factor analyses revealed three memory factors: phonological, visual and central executive. Language was construed as a multifactorial construct, and confirmative factor analyses revealed four factors: lexical-semantic abilities, phonological abilities, syntactic abilities and speech production abilities. Moderate to high correlations were found between the memory and language factors. Structural equation modelling was used to further explore the relations between the different factors. Phonological memory was found to predict phonological abilities; central-executive memory predicted lexical-semantic abilities; and visual memory predicted speech production abilities. Phonological abilities also predicted syntactic abilities. Both the theoretical and clinical implications of the findings are discussed. The reader will be introduced to the concepts of multifactorial components of working memory as well as language impairment. Secondly the reader will recognize that working memory and language impairment factors can be related. Particular emphasis will be placed on phonological memory, central-executive memory and visual memory and their possible prediction of specific components of language impairment.

Fanconi anemia (FA) is a developmental and cancer predisposition disorder in which key, yet unknown, physiological events promoting chromosome stability are compromised. FA cells exhibit excess metaphase chromatid breaks and are universally hypersensitive to DNA interstrand crosslinking agents. Published mutagenesis data from single-gene mutation assays show both increased and decreased mutation frequencies in FA cells. In this review we discuss the data from the literature and from our isogenic fancg knockout hamster CHO cells, and interpret these data within the framework of a molecular model that accommodates these seemingly divergent observations. In FA cells, reduced rates of recovery of viable X-linked hypoxanthine phosphoribosyltransferase (hprt) mutants are characteristically observed for diverse mutagenic agents, but also in untreated cultures, indicating the relevance of the FA pathway for processing assorted DNA lesions. We ascribe these reductions to: (1) impaired mutagenic translesion synthesis within hprt during DNA replication and (2) lethality of mutant cells following replication fork breakage on the X chromosome, caused by unrepaired double-strand breaks or large deletions/translocations encompassing essential genes flanking hprt. These findings, along with studies showing increased spontaneous mutability of FA cells at two autosomal loci, support a model in which FA proteins promote both translesion synthesis at replication-blocking lesions and repair of broken replication forks by homologous recombination and DNA end joining. The essence of this model is that the FANC protein pathway serves to restrict the severity of mutational outcome by favoring base substitutions and small deletions over larger deletions and chromosomal rearrangements.

Spontaneous bacterial peritonitis is the most common infectious complication in cirrhosis. Spontaneous fungal peritonitis is rare and remains unknown. In this work, spontaneous fungal peritonitis as well as risk factors and prognosis are characterized. A retrospective case-control study of 253 consecutive admissions by peritonitis in cirrhotic patients was carried out between 2006 and 2015. Comparison of patients with spontaneous fungal peritonitis (cases) and spontaneous bacterial peritonitis with positive microbiologic ascitic fluid culture (controls) was performed. Variables such as sociodemographic and clinical features, cirrhosis etiology, liver dysfunction scores, ascitic and laboratory parameters, invasive procedures, and prognosis were evaluated. Of the 231 patients, eight (3.5%) developed spontaneous fungal peritonitis, 62.5% of cases being coinfected with bacteria. Candida spp. was isolated in 87.5% of cases, mainly Candida albicans (37.5%) and C. krusei (25.0%). Patients with spontaneous fungal peritonitis had higher ascitic fluid lactate dehydrogenase (288.4±266.6 vs. 161.0±179.5; P=0.011), blood leukocyte count (15187.5±5432.3 vs. 10969.8±6949.5; P=0.028), blood urea nitrogen (69.8±3.1 vs. 36.3±25.5; P=0.001), higher number of invasive procedures (colonoscopy: 25.0 vs. 0.8%, P=0.001; urinary catheterization: 87.5 vs. 49.6%, P=0.038; nasogastric intubation: 87.5 vs. 26.9%, P=0.001), and longer duration of hospital stay (30.0±32.9 vs. 18.9±17.0 days; P=0.031). No statistical difference was found between the two groups for Model for End-Stage Liver Disease, Model for End-Stage Liver Disease-sodium, and Child-Pugh scores. Spontaneous fungal peritonitis was associated with a worse prognosis, particularly severe sepsis/septic shock (87.5 vs. 42.8%, P=0.023), admission in the gastroenterology intensive care unit (87.5 vs. 24.4%; P=0.001), and overall (62.5 vs. 31.9%; P=0.039) or 30-day mortality (50.0 vs. 24.4%; P=0.034), with a mean diagnosis

Master Limited Partnerships (MLPs) and Real Estate Investment Trusts (REITs) are two proposed investment vehicles which have the potential to lower renewable energy assets' high cost of capital; a critical factor in the Department of Energy's goal for renewable energy to achieve grid-parity with traditional sources of electric generation. Due to current U.S. federal income tax laws, regulations, and administrative interpretations, REITs and MLPs cannot finance a significant portion of the cost of renewable energy assets. Efforts are underway to alter these rules by changing the definition of 'real property' (REIT) and 'qualified income' (MLP). However, even with rule changes, both investment vehicles have structural challenges to efficiently finance renewable energy assets. Among them are 1) effectively utilizing the U.S. federal income tax incentives; 2) administratively structuring the investments to not be overly onerous or complicated, given the potential for pooling a relatively large amount of small assets; and 3) attracting and retaining a large enough investment community to participate in the funding opportunities. This report summarizes these challenges so that if proposed federal changes are made, stakeholders have an understanding of the possible outcomes.

The aim of this study was to assess complications related to arthroscopy for femoroacetabular impingement (FAI) and how these complications have changed as we have gained more experience with this procedure. The authors reviewed 200 hips (197 patients). The average patient age was 44.64 years and the mean follow-up time was 28.2 months. All patients underwent hip arthroscopy in the supine position. Clinically, Modified Harris Hip Scores (MHHS) and patient satisfaction with outcome were used. We divided complications into 3 groups: Group 1 related to traction, group 2 related to surgical technique or implant failure, and group 3 related to outcomes. Clinically, the MHHS improved from 69.96 (±6.10) to 80.45 (±7.00), and patient satisfaction with the achieved outcome increased to 8.87 (±0.76). The overall complication rate was 15% (30 of 200 hips). Group 1 consisted of 4 patients with pudendal neuropraxia and 2 patients with ankle joint pain (P = .013). Group 2 consisted of 2 patients with lateral femoral cutaneous neuropraxia, 2 patients with iatrogenic labral perforations, one patient with a labral tear, and 4 patients with femoral head scuffs. There were 4 incidents of instrument breakage. Furthermore, 3 suture anchors failed, a second-degree burn occurred in one patient, and there was incomplete reshaping in 5 hips (P = .045). Group 3 included one patient with a snapping sound and heterotopic ossification. Second-look arthroscopy was performed for 5 hips. All the complications outlined in groups 1 and 2 are related to the learning curve and have statistical significance (P arthroscopy took different forms during the early learning period, but overall complication rates decreased along the learning curve. Surgical technique-related complications such as problems with suture anchors and the reshaping of cam impingements were also considered during the later stage. Level IV, therapeutic case series.

Though a possible cause of late neurological deficits after posterior cervical reconstruction surgery was reported to be an iatrogenic foraminal stenosis caused not by implant malposition but probably by posterior shift of the lateral mass induced by tightening screws and plates, its clinical features and pathomechanisms remain unclear. The aim of this retrospective clinical review was to investigate the clinical features of these neurological complications and to analyze the pathomechanisms by reviewing pre- and post-operative imaging studies. Among 227 patients who underwent cervical stabilization using cervical pedicle screws (CPSs), six patients who underwent correction of cervical kyphosis showed postoperative late neurological complications without any malposition of CPS (ND group). The clinical courses of the patients with deficits were reviewed from the medical records. Radiographic assessment of the sagittal alignment was conducted using lateral radiographs. The diameter of the neural foramen was measured on preoperative CT images. These results were compared with the other 14 patients who underwent correction of cervical kyphosis without late postoperative neurological complications (non-ND group). The six patients in the ND group showed no deficits in the immediate postoperative periods, but unilateral muscle weakness of the deltoid and biceps brachii occurred at 2.8 days postoperatively on average. Preoperative sagittal alignment of fusion area showed significant kyphosis in the ND group. The average of kyphosis correction in the ND was 17.6° per fused segment (range 9.7°-35.0°), and 4.5° (range 1.3°-10.0°) in the non-ND group. A statistically significant difference was observed in the degree of preoperative kyphosis and the correction angles at C4-5 between the two groups. The diameter of the C4-5 foramen on the side of deficits was significantly smaller than that of the opposite side in the ND group. Late postoperative neurological

Full Text Available Objective: to analyze the spectrum of major pathogens of infectious complications in patients with concomitant injury.Materials and methods. 560 biological samples taken from 331 patients were bacteriologically studied. A significant reduction in the isolation frequency of Pseudomonas aeruginosa and an increase in etiological role of Staphylococcus aureus were ascertained in victims with severe injury and concomitant infectious complications during long-term 1982—1984 and 2002—2004 follow-ups.Results. The significant pathogens of infectious complications in concomitant injuries are Staphylococcus aureus, Klebsiella and Escherichia coli. Vancomycin, imipenem/cilastatin, and amikacin are shown to be the most effective drugs for early antibiotic therapy. Thus, the findings reflect structural changes in the leading causative agents of infectious complications in victims with severe injury. If their principal pathogen was Pseudomonas aeruginosa in the 1990s, Staphylococcus aureus and representatives in the colibacillus group prevail today. This supports and generates a need for continuous microbiological monitoring of the causative agents of pyoin-flammatory complications in intensive care units wherein patients with immunosuppression are also present. Pathogen monitoring makes it possible to apply of a well-grounded and rational package of preventive and therapeutic measures and to perform early target antibiotic therapy.

To identify hospitalizations directly related to a complication occurring within 30 days following a transrectal prostate biopsy (PBP). Overall hospitalization rates, mortality rates, potential predisposing factors for complications. Single-center study including all patients who underwent PBP between January 2005 and January 2012. Any hospitalization occurring within 30 days of the PBP for urgent motive was considered potentially attributable to biopsy. We identified the reason for hospitalization with direct complications (urinary infection or fever, rectal bleeding, bladder caillotage, retention) and indirect (underlying comorbidities decompensation) of the biopsy. The contributing factors were anticoagulant or antiplatelet treatment well as waning immunity factors (corticosteroid therapy, HIV, chemotherapy or immunodulateur). Among 2715 men who underwent PBP, there were 120 (4.4%) hospitalizations including 28 (1.03%) caused by the biopsy. Twenty-five (0.92%) were related to a direct complication of biopsy: 14 (56%) for urinary tract infection or fever including 1 hospitalization in intensive care, 5 (20%) for rectal bleeding which required several transfusions 1, 10 (40%) urinary retention and 3 (0.11%) for an indirect complication (2 coronary syndromes and 1 respiratory failure). Several direct complications were associated in 3 cases. Only two hospitalizations associated with rectal bleeding were taking an antiplatelet or anticoagulant. There was no association between hospitalization for urinary tract infections and a decreased immune status. The first death observed in our study occurred at D31 of pulmonary embolism (advanced metastatic patient with bladder cancer). Twenty (60.6%) patients urgently hospitalized did not have prostate cancer. Within this large sample of patients the overall rate of hospitalization due to the realization of a PBP was 1%. It has not been found predictive of complications leading to hospitalization. 4. Copyright © 2016
Full Text Available Corticosteroid therapy for acute alcoholic hepatitis has been demonstrated to enhance survival in patients who are encephalopathic, and who do not have renal failure or gastrointestinal bleeding. However, the complications of steroid therapy in such patients have been less well documented. The authors report two patients with alcoholic liver disease who developed life-threatening infections after steroid therapy was started. The first patient initially developed diabetes followed by Fournier's gangrene of the perineum, and a lung abscess following septic emboli. The second patient had established alcoholic cirrhosis rather than alcoholic hepatitis. She developed a necrotic ulcer on the arm at the site of an intravenous line, which was infected with a rhizopus species. Despite surgical debridement the lesion progressed and contributed to her death. Treatment of alcoholic hepatitis with steroids is not innocuous, and physicians should be aware of the potential for life-threatening complications.

Although the Nuss procedure for pectus excavatum is widely employed, a variety of complications have been reported with relatively high frequency; those that involve cardiac and pericardial injuries can be life threatening. To reduce such dangers, we present here a newly developed sternal elevator. The elevator is horseshoe shaped. Its elevator side has the same curvature as a Nuss introducer, so that interference between devices is minimal and no extra skin incision is needed for the elevator insertion. The elevator holds the sternum forward and enlarges the retrosternal space for safer passage of thoracoscopically guided introducer. The authors have used the elevator for 61 pectus excavatum cases between March 2004 and December 2009 without any major complications. The entire process of substernal tunneling was endoscopically observed, which eliminated any blunt and blind dissection, even in a significantly depressed funnel chest case. With the device, the sternum was effectively elevated again for the placement of the second plate in 30 cases. Our newly developed sternum elevator makes the Nuss procedure safer and more affordable without introducing any extra scarring.

Juvenile nasopharyngeal angiofibroma (JNA) is a benign vascular tumor occurring in young males. Surgery for giant JNA is a complex procedure, with a high risk of major complications. We report a rare case of massive epistaxis in a 15-year-old boy resulting from spontaneous rupture of the intracavernous tract of the internal carotid artery 20 days after resection of a giant JNA by midface degloving. The event was managed by an emergency arteriography with coils selectively deployed to occlude the vessel and to stop hemorrhage. This treatment has been shown to be effective in producing immediate hemostasis and stable long-term occlusion. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Cases of localized and diffuse peritonitis are severe surgical conditions. Despite expanding possibilities for the diagnosis and therapy, patients with peritonitis, its diffuse form in particular, still suffer from high morbidity and mortality. The management of this condition, both in the healthy and especially seriously ill population, is not satisfactory. Recently, we have witnessed an increase in bariatric and metabolic surgery in response to an ever rising number of extremely obese patients worldwide. Bariatric patients belong to a group of seriously ill patients with a significant risk of post-operative complications due to an infection. Although their treatment is identical to that of the normal population, a great emphasis is put on early recognition of complications, and the decision on any potential surgical revision should be actively approached, often necessitating the absence of frequently lengthy paraclinical assessments. We conducted a retrospective analysis of 346 obese bariatric patients undergoing surgical treatment for morbid obesity between August 2011 and August 2015. A total of 6 patients experienced severe complications including two cases of diffuse peritonitis, two cases of localized peritonitis and two cases of intraperitoneal bleeding. One patient died after her discharge from hospital due to toxic shock caused by stomach perforation. We describe two case reports in greater detail to highlight the importance of early detection of complications and a timely surgical intervention. In principle, bariatric patients are a severely ill population where standard diagnostic procedures for post-operative complications often fail. Clinical findings and the surgeons experience are commonly the only diagnostic signs that trigger a surgical revision. In contrast, surgical treatment of post-operative complications in obese patients with peritonitis is virtually identical to that in patients with normal or slightly increased BMI. It involves thorough

A 36-year-old woman was admitted to the Intensive Care Unit for the treatment of severe asthma exacerbation. Her condition of asthma improved with systemic glucocorticosteroids, inhaled beta2-agonist, intravenous theophylline and inhaled anesthesia (isoflurane) under mechanical ventilation. Her consciousness was disturbed even after terminating isoflurane. Brain CT and MRI scan showed cerebral edema and diffuse multiple cerebral micro-bleeds. Glyceol, a hyperosmotic diuretic solution consisting of 10% glycerol and 5% fructose in saline, was administered to decrease cerebral edema. Her consciousness disturbance gradually recovered. Cerebral edema and hemorrhage improved. On the 69th hospital day, she was discharged from hospital without sequelae. This case is a rare one in which severe asthma exacerbation was complicated with cerebral edema and diffuse multiple cerebral hemorrhage. Inhaled anesthesia for asthma exacerbation should be used carefully to avoid delay of diagnosis of central nervous system complications.

Abstract Currently, the association between sarcopenia and long-term prognosis after gastric cancer surgery has not been investigated. Moreover, the association between sarcopenia and postoperative complications remains controversial. This large-scale retrospective study aims to ascertain the prevalence of sarcopenia and assess its impact on postoperative complications and long-term survival in patients undergoing radical gastrectomy for gastric cancer. From December 2008 to April 2013, the clinical data of all patients who underwent elective radical gastrectomy for gastric cancer were collected prospectively. Only patients with available preoperative abdominal CT scan within 30 days of surgery were considered for analysis. Skeletal muscle mass was determined by abdominal (computed tomography) CT scan, and sarcopenia was diagnosed by the cut-off values obtained by means of optimum stratification. Univariate and multivariate analyses evaluating risk factors of postoperative complications and long-term survival were performed. A total of 937 patients were included in this study, and 389 (41.5%) patients were sarcopenic based on the diagnostic cut-off values (34.9 cm2/m2 for women and 40.8 cm2/m2 for men). Sarcopenia was an independent risk factor for severe postoperative complications (OR = 3.010, P sarcopenia did not show significant association with operative mortality. Moreover, sarcopenia was an independent predictor for poorer overall survival (HR = 1.653, P sarcopenia remained an independent risk factor for overall survival and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I. Sarcopenia is an independent predictive factor of severe postoperative complications after radical gastrectomy for gastric cancer. Moreover, sarcopenia is independently associated with overall and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I. PMID:27043677

Several bedside approaches used in combination with thoracoabdominal X-ray are widely used to avoid severe complications that have been reported during nasogastric tube management. Although confirmation by X-ray is considered the gold standard, it is not yet perfect. We present 2 cases of rare complications in which the routine verification methods could not detect all the complications related to the nasogastric tube placement. Case 1 was a 17-year-old male who presented with a brain tumor and repeatedly required nasogastric tube placement. Despite normal auscultatory and X-ray findings, the patient's condition deteriorated rapidly after resuming the enteral nutrition (EN). Computed tomography images showed the presence of hepatic portal venous gas (HPVG). Urgent upper gastrointestinal endoscopy showed esophagogastric submucosal tunneling of the tube that required an emergency open total gastrectomy. Case 2 was a 76-year-old man with long-term EN after stroke. While the last auscultatory verification was normal, he suddenly developed extensive HPVG due to gastric mucosal injury following EN, which resulted in progressive intestinal necrosis, general peritonitis, and death. These 2 cases indicated that routine verification methods consisting of auscultation and X-ray may not be completely reliable, and the awareness of the limitations of these methods should be reaffirmed because expeditious examinations and necessary interventions are critical in preventing life-threatening complications.

Burden of disease studies typically classify individuals with a body mass index (BMI) ≥ 30 kg m(-2) as a single group ('obese') and make comparisons to those with lower BMIs. Here, we review the literature on the additional economic burden associated with severe obesity or classes 3 and 4 obesity (BMI ≥ 40 kg m(-2) ), the fastest growing category of obesity, with the aim of exploring and disaggregating differences in resource use as BMI increases beyond 40 kg m(-2) . We recognize the importance of comparing classes 3 and 4 obesity to less severe obesity (classes 1 and 2) as well as quantifying the single sub-class impacts (classes 3 and 4). Although the latter analysis is the aim of this review, we include results, where found in the literature, for movement between the recognized subclasses and within classes 3 and 4 obesity. Articles presenting data on the economic burden associated with severe obesity were identified from a search of Ovid MEDLINE, EMBASE, EBSCO CINAHL and Cochrane Library databases. Data were extracted on the direct costs, productivity costs and resource use associated with severe obesity along with estimates of the multiplier effects associated with increasing BMI. Fifteen studies were identified, of which four disaggregated resource use for BMI ≥ 40 kg m(-2) . The multiplier effects derived for a variety of different types of costs incurred by the severely obese compared with those of normal weight (18.5 kg m(-2) productivity costs. There are few published data on the economic burden of obesity disaggregated by BMI ≥ 40 kg m(-2) . By grouping people homogenously above a threshold of BMI 40 kg m(-2) , the multiplier effects for those at the highest end of the spectrum are likely to be underestimated. This will, in turn, impact on the estimates of cost-effectiveness for interventions and policies aimed at the severely obese. © 2013 The Authors. obesity reviews © 2013 International

Although Plasmodium ovale is considered the cause of only mild malaria, a case of severe malaria due to P. ovale with acute respiratory distress syndrome is reported. A 37-year old Caucasian man returning home from Angola was admitted for ovale malaria to the National Institute for Infectious Diseases Lazzaro Spallanzani in Rome, Italy. Two days after initiation of oral chloroquine treatment, an acute respiratory distress syndrome was diagnosed through chest X-ray and chest CT scan with intravenous contrast. Intravenous artesunate and oral doxycycline were started and he made a full recovery. Ovale malaria is usually considered a tropical infectious disease associated with low morbidity and mortality. However, severe disease and death have occasionally been reported. In this case clinical failure of oral chloroquine treatment with clinical progression towards acute respiratory distress syndrome is described.

Since neurologic complications of childhood bacterial meningitis are encountered frequently despite antibiotic treatments, the purpose of this study was to analyze early neurologic complications and long-term sequelae of bacterial meningitis in children in a limited-resource country (Kosovo) This study uses a retrospective chart review of children treated for bacterial meningitis in two study periods: 277 treated during years 1997-2002 and 77 children treated during years 2009-2010. Of the 277 vs 77 children treated for bacterial meningitis, 60 (22%) vs 33 (43%) patients developed early neurologic complications, while there were 15 (5.4%) vs 2 (2.6%) deaths. The most frequent early neurologic complications were the following: subdural effusions (13 vs 29%), recurrent seizures (11 vs 8%), and hydrocephalus (3 vs 3%). The relative risk (95% confidence interval) for neurologic complications was the highest in infants (3.56 (2.17-5.92) vs 2.69 (1.62-4.59)) and in cases caused by Haemophilus influenzae 1.94 (1.09-3.18) vs Streptococcus pneumoniae 2.57(1.26-4.47). Long-term sequelae were observed in 10 vs 12% of children, predominantly in infants. The most frequent long-term sequelae were late seizures 9 vs 1%, neuropsychological impairment 1 vs 5%, and deafness 1 vs 3%. In both study periods, the most frequent early neurologic complications of childhood bacterial meningitis were subdural effusions. Long-term sequelae were observed in 10% of children, with late seizures, neuropsychological impairment, and deafness being the most common one. Age prior to 12 months was risk factor for both early neurologic complications and long-term sequelae of bacterial meningitis in children.
Full Text Available There is an increasing population of elderly patients suffering from Alzheimer’s disease (AD, the most common form of dementia. In dentistry, a critical problem associated with these patients is the use of a new denture, as AD patients often refuse dental management and are disturbed by minor changes in their oral environment. Some AD patients have further complications associated with oral dyskinesia, a movement disorder that can make dental management difficult, including the stability of a complete denture. In this case, we successfully fitted a complete maxillary denture using modified bilateral balanced occlusion after multiple tooth extractions under intravenous sedation in a 66-year-old woman with severe AD complicated by oral dyskinesia. Following treatment, her appetite and food intake greatly improved. Providing a well-fitting complete denture applied by modified bilateral balanced occlusion, which removes lateral interference using zero-degree artificial teeth for movement disorder of the jaw in patients with severe AD complicated by oral dyskinesia, helps improve oral function.

Full Text Available BackgroundThe prevalence of hypoglycemia is increasing due to the growing incidence of diabetes and the latest strict guidelines for glycated hemoglobin (HbA1c levels under 7%. This study examined the clinical characteristics, causal factors, and medical costs of severely hypoglycemic patients in an emergency room (ER of Uijeongbu St. Mary's Hospital.MethodsThe study consisted of a retrospective analysis of the characteristics, risk factors, and medical costs of 320 severely hypoglycemic patients with diabetes who presented to an ER of Uijeongbu St. Mary's Hospital from January 1, 2006 to December 31, 2009.ResultsMost hypoglycemic patients (87.5%, 280/320 were over 60 years old with a mean age of 69.5±10.9 years and a mean HbA1c level of 6.95±1.46%. Mean serum glucose as noted in the ER was 37.9±34.5 mg/dL. Renal function was decreased, serum creatinine was 2.0±2.1 mg/dL and estimated glomerular filtration rate (eGFR was 48.0±33.6 mL/min/1.73 m2. In addition, hypoglycemic patients typically were taking sulfonylureas or insulin and a variety of other medications, and had a long history of diabetes.ConclusionSevere hypoglycemia is frequent in older diabetic patients, subjects with low HbA1c levels, and nephropathic patients. Therefore, personalized attention is warranted, especially in long-term diabetics with multiple comorbidities who may not have been properly educated or may need re-education for hypoglycemia.
Severe hyperkalemia occurred in a patient with radiation pneumonitis and glaucoma shortly after beginning prednisone therapy. There was no evidence of renal failure, diabetes, acidosis, increased potassium intake, or significant tissue trauma. Medications having adverse effects on potassium metabolism were considered, and the patient's use of timolol maleate eyedrops was discontinued. His serum potassium level normalized despite continuation of the prednisone therapy. He became hyperkalemic on rechallenge with timolol and normokalemic following its withdrawal. This case indicates that the potential for beta-blocker-induced hyperkalemia exists even with topical appreciation
Full Text Available A 67-year-old male patient with diabetes mellitus and nephritic syndrome under cortisone treatment was admitted to our hospital with fever and severe perianal pain. Upon physical examination, a perianal abscess was identified. Furthermore, the scrotum was gangrenous with extensive cellulitis of the perineum and left lower abdominal wall. Crepitations between the skin and fascia were palpable. A diagnosis of Fournier's gangrene was made. He was treated with immediate extensive surgical debridement under general anesthesia. The patient received broad-spectrum antibiotics, and repeated extensive debridements were performed until healthy granulation was present in the wound. Due to the fact that his left testicle was severely exposed, it was transpositioned into a subcutaneous pocket in the inner side of the left thigh. He was finally discharged on the 57th postoperative day. Fournier's gangrene is characterized by high mortality rates, ranging from 15% to 50% and is an acute surgical emergency. The mainstay of treatment should be open drainage and early aggressive surgical debridement of all necrotic tissue, followed by broad-spectrum antibiotics therapy.
Full Text Available Abstract Background Little is known about the reproductive health of women who survive obstetric complications in poor countries. Our aim was to determine how severe obstetric complications in Burkina Faso affect reproductive events in the first year postpartum. Methods Data were collected from a prospective cohort of women who either experienced life threatening (near-miss pregnancy-related complications or an uncomplicated childbirth, followed from the end of pregnancy to one year postpartum or post-abortum. Documented outcomes include menses resumption, sexual activity resumption, dyspareunia, uptake of contraceptives, unmet needs for contraception and women's reproductive intentions. Participants were recruited in seven hospitals between December 2004 and March 2005 in six towns in Burkina Faso. Results Reproductive events were associated with pregnancy outcome. The frequency of contraceptive use was low in all groups and the method used varied according to the presence or not of a live baby. The proportion with unmet need for contraception was high and varied according to the time since end of pregnancy. Desire for another pregnancy was highest among near-miss women with perinatal death or natural abortion. Women in the near-miss group with induced abortion, perinatal death and natural abortion had significantly higher odds of subsequent pregnancy. Unintended pregnancies were observed mainly in women in the near-miss group with live birth and the uncomplicated delivery group. Conclusions Considering the potential deleterious impact (on health and socio-economic life of new pregnancies in near-miss women, it is important to ensure family planning coverage includes those who survive a severe complication.

Full Text Available Introduction. Infectious and inflammatory complications , such as pneumonia and burn sepsis, often develop in patients with extensive burns, thus causing high mortality. The aim of the work was to determine the risk factors for the development of infectious and inflammatory complications in patients with burns. Materials and methods. The study involved 140 burned patients divided into two groups: Group 1 – 78 patients who underwent necrectomy within 3-7 days after the burn, Group 2 (control – 62 patients with necrectomy performed in later period. Results of the research. In the 1st group pneumonia was diagnosed in 11 (14.10 ± 3.94% patients, sepsis – in 13 (16.67 ± 4.22%. In the control group pneumonia was diagnosed in 20 (32.26 ± 5.94% patients, sepsis – in 23 (37.10 ± 6.13% (p < 0.05. In the burned patients of the main group the development of infectious and inflammatory complications was observed mainly in patients over 45 years of age (43%, that is 2.9 times more often than in the patients of younger age (p < 0.05. In patients with the severity index of burn damage exceeding 90 units complications were diagnosed in 32.14 ± 6.24% of cases, which is 7 times more than in the other subgroup (p < 0.05. In the control group patients with the severity index of destruction exceeding 90 units had complications in 56.41 ± 7.94% of cases, which is 2.6 times more than in patients with less severity index (p = 0.004. If the total area of the skin burns was over 40%, the number of sepsis and pneumonia complications significantly increased in both groups, and was 1.7 times greater than in patients with a smaller area of the burn. If the area of deep skin burns was over 25%, the number of cases of pneumonia and sepsis in patients of the main group increased in 2.4 times, and in the control group it was in 1.6 times higher. Among patients with area of deep burns exceeding 40% the incidence of sepsis and pneumonia was 78% (p = 0.03 in the main

Sulfur mustard (SM) has been used as a chemical warfare agent since the early twentieth century. Despite the large number of studies that have investigated SM induced ocular injuries, few of those studies have also focused on the psychological health status of victims. This study has evaluated the most prominent influences on the psychological health status of patients with severe SM induced ocular injuries. This descriptive study was conducted on 149 Iranian war veterans with severe SM induced eye injuries. The psychological health status of all patients was assessed using the Iranian standardized Symptom Check List 90-Revised (SCL90-R) questionnaire. The results of patients' Global Severity Index (GSI) were compared with the optimal cut-off point of 0.4 that has previously been calculated for GSI in Iranian community. The Mann-Whitney U test, T tests and effect sizes (using Cohen's d) were employed as statistical methods. Data were analyzed using SPSS software. The mean age of patients was 44.86 (SD=8.7) and mean duration of disease was 21.58 (SD=1.20) years. Rate of exposure was once in 99 (66.4%) cases. The mean GSI (1.46) of the study group was higher compared to standardized cut off point (0.4) of the Iranian community. The results of this study showed that the mean of total GSI score was higher in participants with lower educational levels (effect size=0.507), unemployment (effect size=0.464) and having more than 3 children (effect size=0.62). Among the participants, 87 (58.4%) cases had a positive psychological history for hospitalization or receiving outpatient cares previously and 62 (41.6%) cases had a negative psychological history. In addition, the mean of GSI in participants with negative psychological history was lower than those with positive psychological history (Mean Change Difference=-0.621 with SD=0.120). There was a significant difference between positive and negative psychological history with respect to GSI (Pchemical survivors are
Full Text Available Antiphospholipid syndrome is a systemic autoimmune disease with thrombotic tendency. Consensus guidelines for pregnancy with antiphospholipid syndrome recommend low-dose aspirin combined with unfractionated or low-molecular-weight heparin because antiphospholipid syndrome causes habitual abortion. We report a 36-year-old pregnant woman diagnosed with antiphospholipid syndrome receiving anticoagulation treatment. The patient developed left abdominal pain and gross hematuria at week 20 of pregnancy. An initial diagnosis of left ureteral calculus was made. Subsequently abdominal-pelvic computed tomography was required for diagnosis because of the appearance of severe contralateral pain. Computed tomography revealed serious renal hemorrhage, and ureteral stent placement and pain control by patient-controlled analgesia were required. After treatment, continuance of pregnancy was possible and vaginal delivery was performed safely. This is the first case report of serious renal hemorrhage in a pregnant woman with antiphospholipid syndrome receiving anticoagulation treatment and is an instructive case for urological and obstetrical practitioners.

Full Text Available Clostridium difficile infection (CDI represents one of the most common healthcare-associated infections. Due to increasing numbers of recurrences and therapy failures, CDI has become a major disease burden. Studies have shown that fecal microbiota transplantation (FMT can both be a safe and highly efficacious therapy for patients with therapy-refractory CDI. However, patients undergoing solid organ transplantation are at high risk for CDI due to long-term immunosuppression, previous antibiotic therapy, and proton pump inhibitor use. Additionally, these patients may be especially prone to adverse events related to FMT. Here, we report a successful FMT in a patient with severe therapy-refractory CDI after liver transplantation.

Bariatric surgery is currently the treatment of choice for those patients with severe obesity, but the procedure of choice is not clearly established. We describe weight loss and nutritional parameters in severely obese patients after biliopancreatic diversion for 10 years of follow-up. Patients were followed by the same multidisciplinary team, and data are shown for 10 years. Bariatric Analysis and Reporting Outcome System (BAROS) questionnaire, data regarding the evolution of obesity-related diseases, and nutritional parameters are reported. Two hundred ninety-nine patients underwent biliopancreatic diversion, 76.1 % women, initial BMI 50.1 kg/m(2) (7.2). Weight loss was maintained throughout 10 years with EWL% around 65 % and EBMIL% around 70 %. More than 80 % of the patients showed EWL higher than 50 %. Blood pressure, glucose metabolism, and lipid profile clearly improved after surgery. Mean nutritional parameters remained within the normal range during follow-up. Protein malnutrition affected less than 4 % and anemia up to 16 %. Fat-soluble vitamin levels decreased along the time, with vitamin D deficiency in 61.5 % of patients. No significant differences were found either in nutritional parameters or weight loss regarding gastrectomy or gastric preservation, or common limb length longer or shorter than 55 cm Biliopancreatic diversion is an effective surgical procedure in terms of weight loss, quality of life, and evolution of obesity-related diseases. Nutritional deficiencies are less frequent than feared for a malabsorptive procedure, but must be taken into account, especially for fat-soluble vitamins.

Serial determinations, using plasma fibrinogen gel chromatography as well as standard methodology, demonstrated that six children with severe glomerulonephritis, characterized on renal biopsy by glomerular necrosis and crescent formation, had persistent evidence of intravascular coagulation. Based on these observations, therapy with anticoagulants and azathicoagulants and azathioprine was instituted for one year; treatment with anticoagulants was continued for a second year. Anticoagulant therapy was initiated with heparin, followed by oral anticoagulation with phenindione and dipyridamole. In contrast to our earlier experience with similar patients, each of the present patients improved. Urinalyses returned to normal and glomerular filtration rates to near normal values in all patients at the end of the treatment period and have remained so for up to 3.9 years since treatment has been completed. Post-treatment biopsies showed remarkable improvement, with virtually no glomerulosclerosis even in patients who had had a high incidence of glomerular crescents before treatment. It is suggested that the therapeutic regimen favorably influenced the natural history of disease and that plasma fibrinogen chromatographic findings may be helpful in selecting patients likely to benefit from the use of anticoagulant therapy.
A variety of operations have been proposed for the treatment of radiation injuries of the rectum. In this study, the procedure advocated by the late Sir Alan Parks--resection of the diseased segment down to its points of fixation to the vagina, bladder or prostate; with perianal mucosal stripping of the anorectal segment and primary coloanal (pull-through) anastomosis--was performed in 11 patients. In two others, an attempt at colorectal anastomosis was abandoned because of extreme scarring in the pelvis. The procedures were done following definitive treatment of carcinoma of the rectum (seven patients), carcinoma of the cervix (two patients), carcinoma of the uterus (one patient), carcinoma of the ovary (one patient), seminoma (one patient), and carcinoma of the bladder (one patient). One patient died from a pulmonary embolus on the seventh postoperative day. Of the survivors with a coloanal anastomosis, all had successful closure of their temporary colostomies with follow-up from one to six years. In eight, continence was assessed as being good or excellent. Four patients required anastomotic dilation and another required a surgical procedure for anastomotic stricture. There was one instance each of reoperation for small bowel obstruction and ileocolic fistula. There were no instances of recurrence of hemorrhage, fistulas, perineal pain or tenesmus. The Parks procedure obviates the need for a difficult dissection of the lower rectum and separation of tissues damaged by radiation and avoids the need for eversion techniques. Its selective use is advocated for patients suffering from severe radiation injuries of the rectum.

Full Text Available Abstract Infection of a peripheral joint following arthroscopic surgery presents with an incidence of approximately 0.42% an extremely rare entity. However, septic arthritis is a serious situation possibly leading to an irreparable joint damage. Especially at delayed diagnosis patients' safety can be endangered severely. Only few precise statements regarding diagnosis and therapy have been published so far. Besides an accurate analysis of the patient's anamnesis and the assessment of the C-reactive protein especially arthrocentesis is required for diagnostic workup. For early stage infections arthroscopic therapy is proven to be of value. In addition a calculated and consecutive germ-adjusted antibiotic therapy is essential. In case of persisting signs of infection the indication for re-arthroscopy or conversion to open revision has to be stated in time. The number of necessary revisions is dependent on the initial stage of infection. For pain therapy postoperative immobilization of the affected joint is occasionally essential, if otherwise possibly early mobilization of the joint should be performed.

Type 1 diabetes mellitus (T1DM) is a major disease affecting a large number of young patients. In the recent years, retinal vascular imaging has provided an objective assessment of vascular health in patients with T1DM. Our study aimed to review the current literature on retinal vascular parameters in young patients with T1DM in order to understand the following: (i) How retinal vessels are affected in T1DM (ii) How such vascular changes can be predictive of future diabetic microvascular complications METHODS: We performed a systematic review and extracted relevant data from 17 articles. We found significant correlations between retinal vessel changes and diabetes-related risk factors (eg, hypertension, hyperlipidemia, and obesity), diabetes-related features (eg, diabetes duration and glycemic control), and diabetes-related microvascular complications (eg, diabetic retinopathy, nephropathy, and neuropathy). Our findings suggest that retinal microvasculature is associated with both disease severity and complications in young patients with T1DM. © 2016 John Wiley & Sons Ltd.

In hypertrophic and/or very ptotic breasts, skin-reducing mastectomy (SRM) is challenging and the risk of complications is high. Few publications have reported the use of an autologous latissimus dorsi flap (ALDF) in this indication. Most studies opt for implant reconstructions, with a high failure rate. We aimed to identify and present the technical refinements that reduce the risk of reconstruction failure in patients with hypertrophic and/or ptotic breasts with breast cancer or at risk of breast cancer after SRM with immediate breast reconstruction (IBR) utilizing an ALDF. Our retrospective study, covering a period of 18 years, included a series of 60 patients with hypertrophic and/or ptotic breasts who underwent 67 SRM and IBR procedures utilizing an ALDF. The complications were recorded and the risk factors analyzed. Sixty-seven SRMs were reviewed. Forty-nine procedures were performed with an inverted-T scar technique and 18 with a vertical scar technique. The nipple-areola complex (NAC) was preserved in 10 cases. There were eight (11.9%) cases of minor mastectomy flap necrosis after skin-reducing reconstructions, 16 (23.8%) wound dehiscences, no infections, no breast seromas, and no reconstruction failures. Smoking increased the risk of minor mastectomy flap necrosis (P = 0.048) and wound dehiscence (P = 0.002). Previous radiotherapy was associated with minor mastectomy flap necrosis (P = 0.001). The use of an ALDF together with technical refinements that preserve the vascular supply of the skin envelope leads to successful IBR with consistently good aesthetic results. Above all, it avoids failure of the reconstruction in very large or ptotic breasts. © 2017 The American Society for Aesthetic Plastic Surgery, Inc. Reprints and permission: email@example.com

In recent years, most of the focus on improving the quality of paediatric care in low-income countries has been on improving primary care using the Integrated Management of Childhood Illness, and improving triage and emergency treatment in hospitals aimed at reducing deaths in the first 24 hours. There has been little attention paid to improving the quality of care for children with chronic or complex diseases. Children with complicated forms of tuberculosis (TB), including central nervous system and chronic pulmonary TB, provide examples of acute and chronic multisystem paediatric illnesses that commonly present to district-level and second-level referral hospitals in low-income countries. The care of these children requires a holistic clinical and continuous quality improvement approach. This includes timely decisions on the commencement of treatment often when diagnoses are not certain, identification and management of acute respiratory, neurological and nutritional complications, identification and treatment of comorbidities, supportive care, systematic monitoring of treatment and progress, rehabilitation, psychological support, ensuring adherence, and safe transition to community care. New diagnostics and imaging can assist this, but meticulous attention to clinical detail at the bedside and having a clear plan for all aspects of care that is communicated well to staff and families are essential for good outcomes. The care is multidimensional: biomedical, rehabilitative, social and economic, and multidisciplinary: medical, nursing and allied health. In the era of the Sustainable Development Goals, approaches to these dimensions of healthcare are needed within the reach of the poorest people who access district hospitals in low-income countries. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Full Text Available The Bain's co-axial circuit system is fully established in general anaesthesia practice. It is favoured for its light weight and suitability for head and neck surgery. However, there are numerous published reports of malfunction of the inner tube of the Bain's co-axial circuit, with potentially lethal complications for the patient. This report presents a case in which a patient connected to a reused Bain's circuit (Datex-Ohmeda developed severe hypercapnia in the early intraoperative period due to unusual defect of the inner tube. This report tests and outlines the integrity of co-axial circuits and also reviews the available literature.

The most effective therapy in patients with limited-stage small cell lung cancer (LS SCLC) seems to be chemotherapy (using platinum-based regimens) and thoracic radiotherapy (TRT), which is followed by prophylactic cranial irradiation. The analysed group comprised 217 patients who received combined treatment for LS SCLC, i.e. chemotherapy (according to cisplatin and etoposide schedule) and TRT (concurrent in 101 and sequential in 116 patients). The influence of chemoradiotherapy (ChT-RT) schedule on treatment results (frequency of complete response, survival rates, and incidence of treatment failure and complications) was evaluated, and the frequency and severity of pulmonary complications were analysed to identify risk factors. The 5-year survival rates in concurrent vs. sequential ChT-RT schedules were 27.3 vs. 11.7% (overall) and 28 vs. 14.3% (disease-free). The frequencies of adverse events in relation to concurrent vs. sequential therapy were 85.1 vs. 9.5% (haematological complications) and 58.4 vs. 38.8% (pulmonary fibrosis), respectively. It was found that concurrent ChT-RT (hazard ratio, HR 2.75), a total dose equal to or more than 54 Gy (HR 2.55), the presence of haematological complications (HR 1.89) and a lung volume receiving a dose equal to or greater than 20 Gy exceeding 31% (HR 1.06) were the risk factors for pulmonary complications. Pulmonary complications after ChT-RT developed in 82% of patients treated for LS SCLC. In comparison to the sequential approach, concurrent ChT-RT had a positive effect on treatment outcome. However, this is a factor that can impair treatment tolerance, which manifests in the appearance of side effects. (orig.) [de

OBJECTIVE Impaired awareness of hypoglycemia (IAH) and severe hypoglycemic events (SHEs) cause substantial morbidity and mortality in patients with type 1 diabetes (T1D). Current therapies are effective in preventing SHEs in 50–80% of patients with IAH and SHEs, leaving a substantial number of patients at risk. We evaluated the effectiveness and safety of a standardized human pancreatic islet product in subjects in whom IAH and SHEs persisted despite medical treatment. RESEARCH DESIGN AND METHODS This multicenter, single-arm, phase 3 study of the investigational product purified human pancreatic islets (PHPI) was conducted at eight centers in North America. Forty-eight adults with T1D for >5 years, absent stimulated C-peptide, and documented IAH and SHEs despite expert care were enrolled. Each received immunosuppression and one or more transplants of PHPI, manufactured on-site under good manufacturing practice conditions using a common batch record and standardized lot release criteria and test methods. The primary end point was the achievement of HbA1c transplant. RESULTS The primary end point was successfully met by 87.5% of subjects at 1 year and by 71% at 2 years. The median HbA1c level was 5.6% (38 mmol/mol) at both 1 and 2 years. Hypoglycemia awareness was restored, with highly significant improvements in Clarke and HYPO scores (P > 0.0001). No study-related deaths or disabilities occurred. Five of the enrollees (10.4%) experienced bleeds requiring transfusions (corresponding to 5 of 75 procedures), and two enrollees (4.1%) had infections attributed to immunosuppression. Glomerular filtration rate decreased significantly on immunosuppression, and donor-specific antibodies developed in two patients. CONCLUSIONS Transplanted PHPI provided glycemic control, restoration of hypoglycemia awareness, and protection from SHEs in subjects with intractable IAH and SHEs. Safety events occurred related to the infusion procedure and immunosuppression, including bleeding

Indonesia is an endemic malaria country with high levels of morbidity and mortality. In Aceh, by the end of 2016, based on the data from Annual Parasite Incidence, the incidence rate was 0.1 per 1.000 population at risk of malaria. One of severe malaria complications is malaria-related acute kidney injury(MAKI). The death increasesthreefold by the presence of MAKI. A 56 years old male farmer was a resident in Buketmeuh village, Meukek, South Aceh, Indonesia, which was an endemic malaria area. He hadfever for seven days, chills, sweating, joint pain, headache, nausea, vomit, yellow eyes and raved. Concentrated tea-colored urineduring four days before hospital admission with a small amount of urine of 200 cc in 24 hours. The diagnosis established based on the Plasmodium vivax trophozoite finding in the blood smear examination, and the severe malaria clinical descriptions such as black water fever (BWF)with MAKI complications. Artemether injection therapy followed by oral primaquine, dihydroartemisinin and piperaquine phosphate (DHP) and hemodialysis provide a good outcome.
Full Text Available We here report a case of Legionnaires’ disease in a splenectomised patient, complicated by rhabdomyolysis and acute renal failure and characterized by a poor clinical response to moxifloxacin. Splenectomy is not included among the factors, typically associated with higher risk or mortality in patients with Legionellosis. However, our report is consistent with previous case reports describing severe Legionella infections in asplenic subjects. The possibility that functional or anatomic asplenia may be a factor predisposing to severe clinical course or poor response to therapy in patients with Legionella infection cannot be excluded, deserving further investigation in the future. More studies are required in order to clarify the underlying pathophysiological mechanisms that connect asplenia, immunological response to Legionella, and pathogen’s resistance to antibiotics.

A 7-year-old male English Coonhound with suspected myxedema coma complicated by severe hypothermia and metabolic abnormalities was treated with a combination of active external and core rewarming techniques, i.v. and oral administration of levothyroxine, supplemental oxygen, and administration of fluids (0.9% NaCl solution). Myxedema coma develops as a consequence of severe hypothyroidism and is characterized by a hypometabolic, stuporous state. Myxedema coma is associated with a high mortality rate, and most reported cases have involved Doberman Pinschers. Intravenous administration of levothyroxine can be used successfully in combination with oral administration to restore normal metabolic function and assist in warming and thermoregulation, although dosages should be conservative to avoid adverse cardiovascular effects.

Diffusion limitation of phosphate possibly constitutes a serious problem regarding the use of a biofilm reactor for enhanced biological phosphorus removal. A lab-scale reactor for simultaneous removal of phosphorus and nitrate was operated in a continuous alternating mode of operation. For a steady.......4 ± 0.4% (equal to 24 ± 4 mg P/g TS). A simplified computer model indicated the reason to be phosphate diffusion limitation and the model revealed a delicate balance between the obtainable phosphorus contents of the biomass and operating parameters, such as backwash interval, biofilm thickness after...... backwash, and phase lengths. The aspect of diffusion is considered of crucial importance when evaluating the performance of a biofilter for phosphate removal. © 2001 John Wiley & Sons, Inc. Biotechnol Bioeng 76: 77–85, 2001....
Full Text Available Background: Sulfur mustard (SM is a strong bifunctional alkylating agent that causes delayed complications in organs such as lung. Oxidative stress plays a pivotal role in the pathogenesis and progression of many pulmonary diseases. The aim of this study was to investigate the oxidative stress in sputum of SM exposed patients with mild, moderate and severe pulmonary dysfunction and assessing their relationship with pulmonary function. Methods: In this cross–sectional study, oxidative stress biomarkers in sputum were examined on 26 patients with SM-induced bronchiolitis obliterans (9 mild, 14 moderate and 3 severe and 12 matched healthy controls referred to Baqiyatallah Hospital, Tehran between October 2015 and April 2016. Results: Sputum superoxide dismutase, catalase and glutathione S-transferase activities and malondialdehyde level in moderate and severe groups were significantly higher than in the control group (P=0.002, P=0.004, P=0.014 and P=0.009, respectively. Glutathione (GSH level in moderate (22.29%, P=0.025 and severe (45.07%, P=0.004 groups were significantly lower than the control. A decreased in GSH level in severe (41.7% groups was observed as compared with the mild group. Pearson analysis revealed strong correlations between disease severity and oxidative stress biomarkers in sputum of patients with moderate and severe injuries. Conclusions: Oxidative stress is involved in the pathogenesis of patients with moderate and severe pulmonary dysfunction following SM exposure. The presence of enhanced oxidative stress relates to the decline lung function and the progression of the disease. Sputum induction in SM-injured patients can be used to the assessment of the antioxidant status of bronchial secretions.
Full Text Available ObjectiveTo investigate the clinical features and treatment of severe acute pancreatitis (SAP complicated by pancreatic abscess (PA. MethodsThe clinical data of 17 SAP patients with PA who were admitted to Affiliated Hospital of Luzhou Medical College from January 1, 2005 to August 25, 2015 were analyzed retrospectively. The clinical manifestations, therapeutic methods, and outcome were summarized. ResultsOf all the 17 patients, 12 patients underwent surgical operation, among whom 9 were cured, 1 experienced postoperative intestinal fistula, and 2 experienced recurrence of abscess and underwent the surgery again (1 died of multiple organ failure, and the mean hospital stay was (108.29±52.37 d; 5 patients underwent percutaneous catheter drainage, among whom 4 were cured, and 1 underwent surgical treatment due to inadequate drainage, and the mean hospital stay was (53.03±6.71 d. ConclusionAdequate drainage should be performed once a confirmed diagnosis of PA is made, and appropriate drainage methods should be selected based on the patient′s actual condition. Minimally invasive treatment has a good effect, a short length of hospital stay, and few complications, and holds promise for clinical application.

This study investigated how patients with severe aphasia communicated in daily living, which verbal and non-verbal communication skills were spared and which were impaired, and whether activity limitations in communication are related to verbal impairments. Twenty-seven patients with severe aphasia and 9 with moderate aphasia originating from a sample of 102 aphasic persons followed up in a French regional survey were assessed with a communication test and a communication activity limitation questionnaire 12-18 months after a first stroke. Patients with severe aphasia suffered severe activity limitations in communication, with performance 3-fold lower than that of patients with moderate aphasia, and 4-fold lower than scores attained by normals. Both aphasia severity and communication disability at follow-up were related to the initial severity of aphasia. Using a phone, credit card and a chequebook, reading and filling in administrative documents, and communication behaviours involved in social life were the most severely impaired. Non-verbal communication performance was not related to aphasia severity. We conclude that there is a great need for speech therapy research to develop new compensatory or alternative strategies for patients with severe aphasia.

This study examined the clinical utility of the Wechsler Adult Intelligence Scales-Fourth Edition (WAIS-IV) in individuals with complicated mild, moderate or severe TBI. One hundred individuals with TBI (n = 35 complicated mild or moderate TBI; n = 65 severe TBI) and 100 control participants matched on key demographic variables from the WAIS-IV normative dataset completed the WAIS-IV. Univariate analyses indicated that participants with severe TBI had poorer performance than matched controls on all index scores and subtests (except Matrix Reasoning). Individuals with complicated mild/moderate TBI performed more poorly than controls on the Working Memory Index (WMI), Processing Speed Index (PSI), and Full Scale IQ (FSIQ), and on four subtests: the two processing speed subtests (SS, CD), two working memory subtests (AR, LN), and a perceptual reasoning subtest (BD). Participants with severe TBI had significantly lower scores than the complicated mild/moderate TBI on PSI, and on three subtests: the two processing speed subtests (SS and CD), and the new visual puzzles test. Effect sizes for index and subtest scores were generally small-to-moderate for the group with complicated mild/moderate and moderate-to-large for the group with severe TBI. PSI also showed good sensitivity and specificity for classifying individuals with severe TBI versus controls. Findings provide support for the clinical utility of the WAIS-IV in individuals with complicated mild, moderate, and severe TBI.

Full Text Available Background Ocular manifestations of thyroid dysfunction constitute a wide clinical spectrum ranging from minor ocular discomfort, lid retraction, lid lag and ocular injection, to sight threatening eyeball protusion and optic nerve compression. Thyroid-related eye disorders are most commonly associated with Graves' disease, and this most frequently occurs in the setting of hyperthyroidism. However, in 10% of cases, typical eye signs have also been reported in euthyroid and hypothyroid states. The severity of thyroid eye disease has been linked to cigarette smoking. There is very little data specifically reporting the ocular manifestations of thyroid disease among black African patients and there is no known report from Nigeria. This pilot study therefore focused on documenting the ocular signs accompanying thyroid dysfunction in a black African population. Aim To evaluate the pattern of ocular complications, among patients treated for thyroid disorders, in a major Nigerian teaching hospital. Results A total of 75 patients with thyroid dysfunction, were evaluated, comprising 63 females and 12 males. There was a very low prevalence of smoking among patients (<5%. Graves' disease was the commonest thyroid disorder, representing 70% of cases. Seventy-eight percent of patients were hyperthyroid, 11.8% were euthyroid and only 9.8% of patients were hypothyroid. Commonest systemic symptoms were neck swelling (68.6%, weight loss (63.8%, tremors (60.9% and palpitations (59.4%. Two-thirds of patients reported ocular symptoms consisting mainly of painless eye swelling (66.7% and ocular irritation (58%. Conjunctival injection, lid lag and lid retraction were the commonest ocular signs. Chemosis, severe proptosis and ocular motility disorder were very rare. Optic neuropathy was found in 4 patients but was related to pre-existing glaucoma. Majority of patients required only ocular emollients and tear supplements. Conclusion Severe ocular complications of

Cardiology interventions in peripheral hospitals is a challenging task where cardiologist have to fight against time and limited resources. Most of the sudden cardiac deaths occur due to arrhythmia and heart blocks/sinus node dysfunction. Our study is a single peripheral center experience of cardiac devices implantation using a 'C' Arm. The aim of this study was to post procedural complications of cardiac implants done in aresource limited setting under 'C' arm. This study is done at a peripheral cardiology center with no cardiac catheterization laboratory (CCL) facilities. Consecutive patients reporting to cardiology center, between Jan 2015 and Oct 2016, with a definite indication for cardiac device implant were included in the study. All the procedure of implantation was done in the operation theatre under 'C' arm under local anesthesia with continuous cardiac monitoring and critical care back up. Total 58 device implantations were done from Jan 2015 to Oct 2016. The mean age of the patients was 67.15 ± 10.85 years. Males constituted almost two third (68.9%) of patients. The commonest indication for device implantation was sinus node dysfunction in 60.34% followed by complete heart block in 25.86% and ventricular tachycardia in 12.06%. No post procedure infection was observed in our study. Device implantation constitute a major group of life saving interventions in cardiology practice. Our study has emphasised that when appropriate aseptic measures are taken during device implantation at peripheral centres, the complications rate are comparable to interventions done at advance cardiac centres.

This study assessed the association between the severity of diabetes complications using diabetes complications severity index (DCSI) and stage of breast cancer (BC) at diagnosis among elderly women with pre-existing diabetes and incident BC. Using Surveillance, Epidemiology and End Results-Medicare data, we identified women with incident BC during 2004-2011 and pre-existing diabetes (N = 7729). Chi-square tests were used to test for group differences in stage of BC at diagnosis. Multinomial logistic regression was used to examine the associations between the severity of diabetes complications and stage of BC at diagnosis. Overall, women with a DCSI = 2 and a DCSI ≥ 3 were more likely to be diagnosed at advanced stages as compared to those with no diabetes complications. In full adjusted association (after adding BC screening to the analysis model), the severity of diabetes complications was no longer an independent predictor of advanced stages at diagnosis. However, women with a DCSI = 2 were 26% more likely to be diagnosed at stage I (versus stage 0) of BC at diagnosis as compared to those without diabetes complications (OR 1.26, 95% CI 1.03-1.53). The increased likelihood of having advanced-stage BC at diagnosis associated with severity of diabetes-related complications appears to be mediated by lower rates of breast cancer screening among elderly women with pre-existing diabetes complications. Therefore, reducing disparity in receiving breast cancer screening among elderly women with diabetes may reduce the risk of advanced-stage breast cancer diagnosis.

Full Text Available Abstract Background Apical ballooning syndrome (or Takotsubo cardiomyopathy is a syndrome of transient left ventricular apical ballooning. Although first described in Japanese patients, it is now well reported in the Caucasian population. The syndrome mimicks an acute myocardial infarction but is characterised by the absence of obstructive coronary disease. We describe a serious and poorly understood complication of Takotsubo cardiomyopathy. Case Presentation We present the case of a 65 year-old lady referred to us from a rural hospital where she was treated with thrombolytic therapy for a presumed acute anterior myocardial infarction. Four hours after thrombolysis she developed acute pulmonary oedema and a new systolic murmur. It was presumed she had acute mitral regurgitation secondary to a ruptured papillary muscle, ischaemic dysfunction or an acute ventricular septal defect. Echocardiogram revealed severe mitral regurgitation, left ventricular apical ballooning, and systolic anterior motion of the mitral valve with significant left ventricular outflow tract gradient (60–70 mmHg. Coronary angiography revealed no obstructive coronary lesions. She had an intra-aortic balloon pump inserted with no improvement in her parlous haemodynamic state. We elected to replace her mitral valve to correct the outflow tract gradient and mitral regurgitation. Intra-operatively the mitral valve was mildly myxomatous but there were no structural abnormalities. She had a mechanical mitral valve replacement with a 29 mm St Jude valve. Post-operatively, her left ventricular outflow obstruction resolved and ventricular function returned to normal over the subsequent 10 days. She recovered well. Conclusion This case represents a serious and poorly understood association of Takotsubo cardiomyopathy with acute pulmonary oedema, severe mitral regurgitaton and systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction.

Elevated plasma von Willebrand factor antigen (vWF) has been shown to indicate the presence of clinically significant portal hypertension, and thus, predicts the development of clinical events in patients with cirrhosis. To investigate the impact of bacterial translocation and inflammation on vWF, as well as the association between vWF and procoagulant imbalance. Moreover, we assessed whether vWF predicts complications of cirrhosis, independent of the severity of portal hypertension. Our study population comprised 225 patients with hepatic venous pressure gradient (HVPG) ≥ 10 mm Hg without active bacterial infections or hepatocellular carcinoma. vWF correlated with markers of bacterial translocation (lipopolysaccharide-binding protein [LBP; ρ = 0.201; P = 0.021]), inflammation (interleukin 6 [IL-6; ρ = 0.426; P protein [CRP; ρ = 0.249; P protein C ratio; ρ = 0.507; P model for transplant-free mortality. Finally, the independent prognostic value of vWF/CRP groups for mortality was confirmed by competing risk analysis. Our results demonstrate that vWF is not only a marker of portal hypertension but also independently linked to bacterial translocation, inflammation and procoagulant imbalance, which might explain its HVPG-independent association with most clinical events. Prognostic groups based on vWF/CRP efficiently discriminate between patients with a poor 5-year survival and patients with a favourable prognosis. © 2018 John Wiley & Sons Ltd.

Objective To investigate the accuracy of three clinical scales for predicting severe disease (severe dehydration or death) in children with diarrhea in a resource-limited setting. Methods Participants included 178 children admitted to three Rwandan hospitals with diarrhea. A local physician or nurse assessed each child on arrival using the World Health Organization (WHO) severe dehydration scale and the Centers for Disease Control (CDC) scale. Children were weighed on arrival and daily until they achieved a stable weight, with a 10% increase between admission weight and stable weight considered severe dehydration. The Clinical Dehydration Scale was then constructed post-hoc using the data collected for the other two scales. Receiver Operator Characteristic (ROC) curves were constructed for each scale compared to the composite outcome of severe dehydration or death. Results The WHO severe dehydration scale, CDC scale, and Clinical Dehydration Scale had areas under the ROC curves (AUCs) of 0.72 (95% CI 0.60, 0.85), 0.73 (95% CI 0.62, 0.84), and 0.80 (95% CI 0.71, 0.89), respectively, in the full cohort. Only the Clinical Dehydration Scale was a significant predictor of severe disease when used in infants, with an AUC of 0.77 (95% CI 0.61, 0.93), and when used by nurses, with an AUC of 0.78 (95% CI 0.63, 0.93). Conclusions While all three scales were moderate predictors of severe disease in children with diarrhea, scale accuracy varied based on provider training and age of the child. Future research should focus on developing or validating clinical tools that can be used accurately by nurses and other less-skilled providers to assess all children with diarrhea in resource-limited settings.

Full Text Available Aphasia intervention has made increasing use of technology in recent years. The evidence base, which is largely limited to the investigation of spoken language outcomes, indicates positive treatment effects for people with mild to moderate levels of aphasia. Outcomes for those with severe aphasia however, are less well documented and - where reported - present less consistent gains for measures of spoken output. This study investigates the effects of a purpose-built gesture therapy technology for people with severe aphasia: GeST+. Study outcomes show significant improvement in gesture production abilities for adults with severe aphasia following computer intervention. They indicate no transfer of effects into naming gains or interactive gesture. Outcomes offer encouraging results for computer therapy methods within this hitherto under-researched population but indicate a need for further refinement of interventions in order to maximize persistence of effects and generalization into everyday communication.

How do mental health professionals perceive the role of physiotherapists in the care of people with severe and persistent mental illness, and what factors do they perceive as influencing access to physiotherapy services? How do people with severe and persistent mental illness understand the potential role of physiotherapy in their healthcare, and what factors do they perceive as influencing access to physiotherapy services? Qualitative study. Twenty-four mental health professionals and 35 people with severe and persistent mental illness. Interview schedules were developed to explore participants' understanding of physiotherapy, as well as barriers and enablers to service access. Focus groups and interviews were conducted for each group of participants. Transcripts were analysed using an inductive approach to derive key themes. Both the mental health professionals and the people with severe and persistent mental illness expressed a limited understanding of the role and relevance of physiotherapy for physical health in mental healthcare. Common barriers to service access were cost, transport and lack of motivation. Likewise, enablers of reduced cost, provision of transport and education about physiotherapy to improve their understanding were identified. The health system structure and perceived lack of mental health knowledge by physiotherapists influenced referrals from mental health professionals. Consequently, education in mental health for physiotherapists and integration of the service within mental health were identified as potential enablers to physiotherapy access. Limited understanding about physiotherapy and its relevance to physical health in mental healthcare among mental health professionals and people with severe and persistent mental illness was found to be a key factor influencing service access. Limited physiotherapy presence and advocacy within mental health were also highlighted. There is a need for greater understanding about physiotherapy among

Background: Diarrhea affects a large proportion of children with severe acute malnutrition (SAM). However, its etiology and clinical consequences remain unclear. Objective: We investigated diarrhea, enteropathogens, and systemic and intestinal inflammation for their interrelation and their associations with mortality in children with SAM. Design: Intestinal pathogens (n = 15), cytokines (n = 29), fecal calprotectin, and the short-chain fatty acids (SCFAs) butyrate and propionate were determined in children aged 6–59 mo (n = 79) hospitalized in Malawi for complicated SAM. The relation between variables, diarrhea, and death was assessed with partial least squares (PLS) path modeling. Results: Fatal subjects (n = 14; 18%) were younger (mean ± SD age: 17 ± 11 compared with 25 ± 11 mo; P = 0.01) with higher prevalence of diarrhea (46% compared with 18%, P = 0.03). Intestinal pathogens Shigella (36%), Giardia (33%), and Campylobacter (30%) predominated, but their presence was not associated with death or diarrhea. Calprotectin was significantly higher in children who died [median (IQR): 1360 mg/kg feces (2443–535 mg/kg feces) compared with 698 mg/kg feces (1438–244 mg/kg feces), P = 0.03]. Butyrate [median (IQR): 31 ng/mL (112–22 ng/mL) compared with 2036 ng/mL (5800–149 ng/mL), P = 0.02] and propionate [median (IQR): 167 ng/mL (831–131 ng/mL) compared with 3174 ng/mL (5819–357 ng/mL), P = 0.04] were lower in those who died. Mortality was directly related to high systemic inflammation (path coefficient = 0.49), whereas diarrhea, high calprotectin, and low SCFA production related to death indirectly via their more direct association with systemic inflammation. Conclusions: Diarrhea, high intestinal inflammation, low concentrations of fecal SCFAs, and high systemic inflammation are significantly related to mortality in SAM. However, these relations were not mediated by the presence of intestinal pathogens. These findings offer an important understanding of

Children with asthma may be less physically active than their healthy peers. We aimed to investigate whether perceived exercise limitation (EL) was associated with lung function or bronchial hyper-responsiveness (BHR), socioeconomic factors, prenatal smoking, overweight, allergic disease, asthma severity, or physical activity (PA). The 302 children with asthma from the 10-year examination of the Environment and Childhood Asthma birth cohort study underwent a clinical examination including perceived EL (structured interview of child and parent(s)), measure of overweight (body mass index by sex and age passing through 25 kg/m 2 or above at 18 years), exercise-induced bronchoconstriction (forced expiratory volume in one-second (FEV 1 ) pre- and post-exercise), methacholine bronchial challenge (severe BHR; provocative dose causing ≥20% decrease in FEV 1 ≤ 1 μmol), and asthma severity score (dose of controller medication and exacerbations last 12 months). Multivariate logistic regression analyses were conducted to assess associations with perceived EL. In the final model explaining 30.1%, asthma severity score (OR: 1.49, (1.32, 1.67)) and overweight (OR: 2.35 (1.14, 4.82)) only were significantly associated with perceived EL. Excluding asthma severity and allergic disease, severe BHR (OR: 2.82 (1.38, 5.76)) or maximal reduction in FEV 1 post-exercise (OR: 1.48 (1.10, 1.98)) and overweight (OR: 2.15 (1.13, 4.08) and 2.53 (1.27, 5.03)) explained 9.7% and 8.4% of perceived EL, respectively. Perceived EL in children with asthma was independently associated with asthma severity and overweight, the latter doubling the probability of perceived EL irrespectively of asthma severity, allergy status, socioeconomic factors, prenatal smoking, or PA. © 2016 John Wiley & Sons A/S.

To elucidate the incidence of and risk factors for severe hypertensive disorders (HD) and related maternal complications in uncomplicated twin pregnancies that reached 36 weeks' gestation. We conducted a prospective cohort study of twin pregnancies delivered after 36 weeks' gestation. Cases of twin-twin transfusion syndrome, twin anemia-polycythemia sequence, malformed fetuses, monoamniotic twins, selective reduction, fetal therapy and HD or fetal death before 35 weeks' gestation were excluded. The study's primary outcome was the incidence of severe maternal complications, including severe HD, eclampsia, placental abruption, HELLP (hemolysis, elevated liver enzyme and low platelet) syndrome, pulmonary edema and cerebrovascular disease. Perinatal factors associated with the primary outcome were identified using a multivariate logistic regression model. In 330 enrolled women, the number of cases with the primary outcome was 28 (8.5%; 95% confidence interval 5.9-12.0), including 25 cases of severe HD and each one case of placental abruption, HELLP syndrome and eclampsia. The rate of severe maternal complications significantly increased with gestational age, demonstrating 1.2% at 36 weeks, 3.9% at 37 weeks and 6.4% at 38 weeks. Only gestational proteinuria was identified as the independent risk factor for severe maternal complications (adjusted odds ratio 17.1 [95% confidence interval 6.71-45.4]). Severe maternal HD and related complications increased from late preterm to early term; particularly, patients with gestational proteinuria were at high risk. © 2018 Japan Society of Obstetrics and Gynecology.

The aim of this study was to explore how activity of daily living (ADL) stages and the perception of unmet needs for home accessibility features associate with a history of falling. Participants were from a nationally representative sample from the Second Longitudinal Survey of Aging conducted in 1994. The sample included 9250 community-dwelling persons 70 yrs or older. The associations of ADL stage and perception of unmet needs for home accessibility features with a history of falling within the past year (none, once, or multiple times) were explored after accounting for sociodemographic characteristics and comorbidities using a multinomial logistic regression model. The adjusted relative risk of falling more than once peaked at 4.30 (95% confidence interval, 3.29-5.61) for persons with severe limitation (ADL-III) compared those with no limitation (ADL-0) then declined for those at complete limitation (ADL-IV). The adjusted relative risks of falling once and multiple times were 1.42 (95% confidence interval, 1.07-1.87) and 1.85 (95% confidence interval, 1.44-2.36), respectively, for those lacking home accessibility features. Risk of falling appeared greatest for those whose homes lacked accessibility features and peaked at intermediate ADL limitation stages, presumably at a point when people have significant disabilities but sufficient function to remain partially active.
This report constitutes the supporting material for a lecture on severe accidents which could occur on PWR type nuclear reactors. It is assumed for present purposes that the reader has at least a rudimentary acquaintance with the basics of general physics if not with the operating processes of these reactors. After defining what is meant by a ''severe accident'' on a reactor, the possible phenomenology of such an accident is qualitatively described: loss of coolant and loss of containment integrity. A certain number of elements are then given for the quantitative assessment of these phenomena involving possible radioactivity transfers within and outside the plant. In conclusion, available means are indicated for the limitation and control of these environmental transfers. (author). 5 refs, figs

For the last 3 decades, the central problem of dose prescription in gynaecological cancers was to move from idealised standards (e.g. the Manchester system) to individualised dose-volume prescriptions and subsequent corrections based upon the actual dose distribution in each patient. Individual dose distributions were not available until the late sixties. A consensus for reporting brachytherapy doses was reached in 1975 in the GEC (Groupe Europeen de Curietherapie) and won international recognition in 1985 (ICRU report 38). Reporting complications with a coherent and comprehensive scale is now feasible with the wide acceptance of the French-Italian syllabus. The combined use of all these tools provides the basis for preventing complications. The risk of developing complications is correlated with individual dosimetric parameters such as the dose to reference points for critical organs, dose-volume distribution of complications, dose-rate variations at points of reference. A 25-year experience based upon the dosimetric data of 1943 patients will be reported to document these correlations. During that period, rate of grade 3 and 4 complications fell from 15% to 5% (all stages together). Further improvement should now lead to the eradication of severe complications related to inadequate dose prescription in curative radiotherapy of cervix cancers

The most effective therapy in patients with limited-stage small cell lung cancer (LS SCLC) seems to be chemotherapy (using platinum-based regimens) and thoracic radiotherapy (TRT), which is followed by prophylactic cranial irradiation. The analysed group comprised 217 patients who received combined treatment for LS SCLC, i.e. chemotherapy (according to cisplatin and etoposide schedule) and TRT (concurrent in 101 and sequential in 116 patients). The influence of chemoradiotherapy (ChT-RT) schedule on treatment results (frequency of complete response, survival rates, and incidence of treatment failure and complications) was evaluated, and the frequency and severity of pulmonary complications were analysed to identify risk factors. The 5-year survival rates in concurrent vs. sequential ChT-RT schedules were 27.3 vs. 11.7% (overall) and 28 vs. 14.3% (disease-free). The frequencies of adverse events in relation to concurrent vs. sequential therapy were 85.1 vs. 9.5% (haematological complications) and 58.4 vs. 38.8% (pulmonary fibrosis), respectively. It was found that concurrent ChT-RT (hazard ratio, HR 2.75), a total dose equal to or more than 54 Gy (HR 2.55), the presence of haematological complications (HR 1.89) and a lung volume receiving a dose equal to or greater than 20 Gy exceeding 31% (HR 1.06) were the risk factors for pulmonary complications. Pulmonary complications after ChT-RT developed in 82% of patients treated for LS SCLC. In comparison to the sequential approach, concurrent ChT-RT had a positive effect on treatment outcome. However, this is a factor that can impair treatment tolerance, which manifests in the appearance of side effects. (orig.)

Percutaneous endoscopic colostomy (PEC) is increasingly proposed as an alternative to surgery to treat various disorders, including acute colonic pseudo-obstruction, chronic intestinal pseudo-obstruction and relapsing sigmoid volvulus. We report on a severe complication that occurred two months after PEC placement. A 74-year-old man with a history of chronic intestinal pseudo-obstruction evolving since 8 years was readmitted to our hospital and received PEC to provide long-standing relief. The procedure was uneventful and greatly improved the patient’s quality of life. Two months later, the patient developed acute stercoral peritonitis. At laparotomy, the colostomy flange was embedded in the abdominal wall but no pressure necrosis was found at the level of the colonic wall. This complication was likely related to inadvertent traction of the colostomy tube. Subtotal colectomy with terminal ileostomy was performed. We review the major features of 60 cases of PEC reported to date, including indications and complications. PMID:17465514

We compared two imipenem regimens for prevention of septic complications in patients with severe acute necrotizing pancreatitis (ANP). Prospective, randomized open clinical trial involving intensive care units of 14 Spanish Hospitals. 92 patients with ANP. Imipenem/cilastatin was administered at 500 mg four times daily starting at the time of diagnosis of ANP, within the first 96 h from the onset of symptoms. Patients were randomized to receive antibiotic prophylaxis either for 14 days (group 1) or at least for 14 days and as long as major systemic complications of the disease persisted (group 2). Antibiotic was maintained in group 2 for 19.7+/-10.9 days. The incidence of infected pancreatic necrosis, pancreatic abscess, and extrapancreatic infections was 11%, 17%, and 28% in group 1 and 17.4%, 13%, and 35% in group 2 (n.s.). Pancreatic or extrapancreatic infection by Candida albicans occurred in 7% and 22% of patients. Global mortality was 18.5% (10.9% secondary to septic complications), without differences between groups. In patients with persisting systemic complications at day 14 mortality was almost always secondary to septic complications and decreased from 25% (group 1) to 8.8% (group 2) by maintaining antibiotic prophylaxis. Compared to a 14-day imipenem prophylaxis, a longer antibiotic administration in patients with ANP is not associated with a reduction in the incidence of septic complications of the disease. However, prolonged imipenem administration in patients with persisting systemic complications tends to reduce mortality in ANP compared to a 14-days regimen.

The local failure strains of essential design elements of a reactor vessel are investigated. The size influence of the structure is of special interest. Typical severe accident conditions including elevated temperatures and dynamic loads are considered. The main part of work consists of test families with specimens under uniaxial and biaxial load. Within one test family the specimen geometry and the load conditions are similar, but the size is varied up to reactor dimensions. Special attention is given to geometries with a hole or a notch causing non-uniform stress and strain distributions typical for the reactor vessel. A key problem is to determine the local failure strain. Here suitable methods had to be developed including the so-called 'vanishing gap method', and the 'forging die method'. They are based on post-test geometrical measurements of the fracture surfaces and reconstructions of the related strain fields using finite element models. The results indicate that stresses versus dimensionless deformations are approximately size independent up to failure for specimens of similar geometry under similar load conditions. Local failure strains could be determined. The values are rather high and size dependent. Statistical evaluation allow the proposal of limit strains which are also size dependent. If these limit strains are not exceeded, the structures will not fracture

Maternal overweight and obesity increase risks of pregnancy and delivery complications and neonatal mortality, but the mechanisms are unclear. The objective of the study was to investigate associations between maternal body mass index (BMI) in early pregnancy and severe asphyxia-related outcomes in infants delivered at term (≥37 weeks). A nation-wide Swedish cohort study based on data from the Medical Birth Register included all live singleton term births in Sweden between 1992 and 2010. Logistic regression analyses were used to obtain odds ratios (ORs) with 95% CIs for Apgar scores between 0 and 3 at 5 and 10 minutes, meconium aspiration syndrome, and neonatal seizures, adjusted for maternal height, maternal age, parity, mother's smoking habits, education, country of birth, and year of infant birth. Among 1,764,403 term births, 86% had data on early pregnancy BMI and Apgar scores. There were 1,380 infants who had Apgar score 0-3 at 5 minutes (absolute risk = 0.8 per 1,000) and 894 had Apgar score 0-3 at 10 minutes (absolute risk = 0.5 per 1,000). Compared with infants of mothers with normal BMI (18.5-24.9), the adjusted ORs (95% CI) for Apgar scores 0-3 at 10 minutes were as follows: BMI 25-29.9: 1.32 (1.10-1.58); BMI 30-34.9: 1.57 (1.20-2.07); BMI 35-39.9: 1.80 (1.15-2.82); and BMI ≥40: 3.41 (1.91-6.09). The ORs for Apgar scores 0-3 at 5 minutes, meconium aspiration, and neonatal seizures increased similarly with maternal BMI. A study limitation was lack of data on effects of obstetric interventions and neonatal resuscitation efforts. Risks of severe asphyxia-related outcomes in term infants increase with maternal overweight and obesity. Given the high prevalence of the exposure and the severity of the outcomes studied, the results are of potential public health relevance and should be confirmed in other populations. Prevention of overweight and obesity in women of reproductive age is important to improve perinatal health.

Full Text Available Abstract Background Acute kidney injury (AKI is a complication of severe malaria, and rhabdomyolysis with myoglobinuria is an uncommon cause. We report an unusual case of severe falciparum malaria with dengue coinfection complicated by AKI due to myoglobinemia and myoglobinuria while maintaining a normal creatine kinase (CK. Case presentation A 49-year old Indonesian man presented with fever, chills, and rigors with generalized myalgia and was diagnosed with falciparum malaria based on a positive blood smear. This was complicated by rhabdomyolysis with raised serum and urine myoglobin but normal CK. Despite rapid clearance of the parasitemia with intravenous artesunate and aggressive hydration maintaining good urine output, his myoglobinuria and acidosis worsened, progressing to uremia requiring renal replacement therapy. High-flux hemodiafiltration effectively cleared his serum and urine myoglobin with recovery of renal function. Further evaluation revealed evidence of dengue coinfection and past infection with murine typhus. Conclusion In patients with severe falciparum malaria, the absence of raised CK alone does not exclude a diagnosis of rhabdomyolysis. Raised serum and urine myoglobin levels could lead to AKI and should be monitored. In the event of myoglobin-induced AKI requiring dialysis, clinicians may consider using high-flux hemodiafiltration instead of conventional hemodialysis for more effective myoglobin removal. In Southeast Asia, potential endemic coinfections that can also cause or worsen rhabdomyolysis, such as dengue, rickettsiosis and leptospirosis, should be considered.

To present a case of Graves' disease complicated by methimazole induced agranulocytosis treated with therapeutic plasma exchange (TPE) and review of the literature. A 21-year-old patient with a history of Graves' disease presented to the endocrine clinic. His history was significant for heat intolerance, weight loss, and tremors. Upon examination he had tachycardia, smooth goiter, thyroid bruit, and hyperactive reflexes. He was started on methimazole and metoprolol and thyroidectomy was to be done once his thyroid function tests normalized. On follow-up, the patient symptoms persisted. Complete blood count done showed a white blood cell count of 2100 (4000-11,000 cells/cu mm) with a neutrophil count of 400 cells/cu mm, consistent with neutropenia. He was admitted to the hospital and underwent 3 cycles of TPE and was also given filgrastim. He improved clinically and his thyroxine (T4) levels also came down. Thyroidectomy was done. He was discharged on levothyroxine for postsurgical hypothyroidism. Plasmapheresis may be useful in the treatment of hyperthyroidism. It works by removing protein bound hormones and also possibly inflammatory cytokines. Further studies are needed to clarify the role of various modalities of TPE in the treatment of hyperthyroidism.

Previous research has suggested that two color patches can be consolidated into visual short-term memory (VSTM) via an unlimited parallel process. Here we examined whether the same unlimited-capacity parallel process occurs for two oriented grating patches. Participants viewed two gratings that were presented briefly and masked. In blocks of trials, the gratings were presented either simultaneously or sequentially. In Experiments 1 and 2, the presentation of the stimuli was followed by a location cue that indicated the grating on which to base one's response. In Experiment 1, participants responded whether the target grating was oriented clockwise or counterclockwise with respect to vertical. In Experiment 2, participants indicated whether the target grating was oriented along one of the cardinal directions (vertical or horizontal) or was obliquely oriented. Finally, in Experiment 3, the location cue was replaced with a third grating that appeared at fixation, and participants indicated whether either of the two test gratings matched this probe. Despite the fact that these responses required fairly coarse coding of the orientation information, across all methods of responding we found superior performance for sequential over simultaneous presentations. These findings suggest that the consolidation of oriented gratings into VSTM is severely limited in capacity and differs from the consolidation of color information.

Neonatal near miss cases occur more often than neonatal deaths and could enable a more comprehensive analysis of risk factors, short-term outcomes and prognostic factors in neonates born to mothers with severe obstetric complications. The objective was to assess the incidence, presentation and perinatal outcomes of severe obstetric morbidity in two referral hospitals in Central Uganda. A prospective cohort study was conducted between March 1, 2013 and February 28, 2014, in which all newborns from cases of severe pregnancy and childbirth complications were eligible for inclusion. The obstetric conditions included obstetric haemorrhage, hypertensive disorders, obstructed labour, chorioamnionitis and pregnancy-specific complications such as malaria, anemia and premature rupture of membranes. Still births, neonatal deaths and neonatal near miss cases (defined using criteria that employed clinical features, presence of organ-system dysfunction and management provided to the newborns were compiled). Stratified and multivariate logistic regression analysis was conducted to identify risk factors for perinatal death. Of the 3100 mothers, 192 (6.2%) had abortion complications. Of the remainder, there were 2142 (73.1%) deliveries, from whom the fetal outcomes were 257 (12.0%) still births, 369 (17.2%) neonatal deaths, 786 (36.7%) neonatal near misses and 730 (34.1%) were newborns with no or minimal life threatening complications. Of the 235 babies admitted to the neonatal intensive care unit (NICU), the main reasons for admission were prematurity for 64 (26.8%), birth asphyxia for 59 (23.7%), and grunting respiration for 26 (11.1%). Of the 235 babies, 38 (16.2%) died in the neonatal period, and of these, 16 died in the first 24 hours after admission. Ruptured uterus caused the highest case-specific mortality of 76.8%, and led to 16.9% of all newborn deaths. Across the four groups, there were significant differences in mean birth weight, p = 0.003. Antepartum hemorrhage
Full Text Available A 33 weeks’ gestation, a baby with rhesus hemolytic disease (RHD, who had received intrauterine transfusions twice, developed cholestatic hepatic disease and late hyporegenerative anemia. Her serum ferritin and bilirubin levels increased to 8842 ng/ml and 17.9 mg/dl, respectively. Liver biopsy showed cholestasis and severe iron overload. Treatment with recombinant erythropoietin (rHuEPO decreased the transfusion need, and intravenous deferoxamine resulted in a marked decreased in serum ferritin levels and normalization of liver function. In patients who have undergone intrauterine transfusions due to RHD, hyperferritinemia and late hyporegenerative anemia should be kept in mind. Chelation therapy in cases with symptomatic hyperferritinemia and rHuEPO treatment in cases with severe hyporegenerative anemia should be considered.

Full Text Available Introduction. The realization of red cell exchange (RCE in Africa faces the lack of blood, transfusion safety, and equipment. We evaluated its efficacy and safety in severe complications of sickle cell disease. Patients and Method. Manual partial RCE was performed among sickle cell patients who had severe complications. Efficacy was evaluated by clinical evolution, blood count, and electrophoresis of hemoglobin. Safety was evaluated on adverse effects, infections, and alloimmunization. Results. We performed 166 partial RCE among 44 patients including 41 homozygous (SS and 2 heterozygous composites SC and 1 S/β0-thalassemia. The mean age was 27.9 years. The sex ratio was 1.58. The regression of symptoms was complete in 100% of persistent vasoocclusive crisis and acute chest syndrome, 56.7% of intermittent priapism, and 30% of stroke. It was partial in 100% of leg ulcers and null in acute priapism. The mean variations of hemoglobin and hematocrit rate after one procedure were, respectively, +1.4 g/dL and +4.4%. That of hemoglobin S after 2 consecutive RCE was −60%. Neither alloimmunization nor viral seroconversion was observed. Conclusion. This work shows the feasibility of manual partial RCE in a low-resource setting and its efficacy and safety during complications of SCD outside of acute priapism.

Introduction The realization of red cell exchange (RCE) in Africa faces the lack of blood, transfusion safety, and equipment. We evaluated its efficacy and safety in severe complications of sickle cell disease. Patients and Method Manual partial RCE was performed among sickle cell patients who had severe complications. Efficacy was evaluated by clinical evolution, blood count, and electrophoresis of hemoglobin. Safety was evaluated on adverse effects, infections, and alloimmunization. Results We performed 166 partial RCE among 44 patients including 41 homozygous (SS) and 2 heterozygous composites SC and 1 S/β0-thalassemia. The mean age was 27.9 years. The sex ratio was 1.58. The regression of symptoms was complete in 100% of persistent vasoocclusive crisis and acute chest syndrome, 56.7% of intermittent priapism, and 30% of stroke. It was partial in 100% of leg ulcers and null in acute priapism. The mean variations of hemoglobin and hematocrit rate after one procedure were, respectively, +1.4 g/dL and +4.4%. That of hemoglobin S after 2 consecutive RCE was −60%. Neither alloimmunization nor viral seroconversion was observed. Conclusion This work shows the feasibility of manual partial RCE in a low-resource setting and its efficacy and safety during complications of SCD outside of acute priapism. PMID:28584527

Full Text Available Objectives. A symptomatic renal pseudoaneurysm (RPA is a severe complication after open partial nephrectomy (OPN. The aim of our study was to assess incidence and risk factors for RPA formation. Furthermore, we present our management strategy. Patients and Methods. Clinical records of consecutive patients undergoing OPN were assessed for surgical outcome and postoperative complications. Renal masses were risk stratified for tumor complexity according to the PADUA score. Uni- and multivariate analysis for symptomatic RPAs were performed using the t-tests and logistic regression. Results. We identified 233 patients treated with OPN. Symptomatic RPAs were observed in 13 (5.6% patients, on average 14 (4–42 days after surgery. Uni- and multivariate analysis identified tumor complexity to be an independent predictor for symptomatic RPAs (p=0.004. There was a significant correlation between RPAs and transfusion and the duration of stay (p<0.001 and p=0.021. Symptomatic RPAs were diagnosed with CT scans and successfully treated with arterial embolization. Discussion. Symptomatic RPAs are not uncommon after OPN for high-risk renal masses. A high nephrometry score is a predictor for this severe complication and may enable a risk-stratified followup. RPAs can successfully be located by CT angiography, which enables targeted angiographic treatment.

To study the clinical effect and safety of high-frequency oscillatory ventilation (HFOV) combined with pulmonary surfactant (PS) in the treatment of neonatal severe meconium aspiration syndrome (MAS) complicated by neonatal pulmonary hemorrhage (NPH). A total of 48 children with severe MAS complicated by NPH were enrolled, and a retrospective analysis was performed for the clinical effects of HFOV+PS (trial group, 25 children) and HFOV alone (control group, 23 children). The blood gas parameters, oxygenation index (OI), PaO 2 /FiO 2 (P/F) value, duration of pulmonary hemorrhage, ventilation time, length of hospital stay, incidence of complications, and outcome were compared between the two groups. At 6, 12, 24, and 48 hours after treatment, the trial group had significantly better PaO 2 , OI, and P/F value than the control group (Phemorrhage (P0.05). HFOV combined with PS can better improve oxygenation function and shorten the duration of NPH and ventilation time. Meanwhile, it does not increase the incidence of adverse events. Therefore, it is a safe and effective therapy.

Objective To test the efficacy of Counselor-Assisted Problem Solving (CAPS) versus an internet resources comparison (IRC) condition in reducing behavior problems in adolescents following traumatic brain injury (TBI). Design Randomized clinical trial with interviewers naïve to treatment condition. Setting Three large tertiary children's hospitals and two general hospitals with pediatric commitment. Participants 132 children ages 12-17 years hospitalized during the previous 6 months for moderate to severe TBI. Interventions Participants in CAPS (n = 65) completed 8-12 online modules providing training in problem solving, communication skills, and self-regulation and subsequent synchronous videoconferences with a therapist. Participants in the IRC group (n = 67) received links to internet resources about pediatric TBI. Main Outcome Measures Child Behavior Checklist (CBCL) administered before and after completion of treatment (i.e., approximately six months after treatment initiation). Results Post hoc analysis of covariance (ANCOVA), controlling for pre-treatment scores, was used to examine group differences in behavior problems in the entire sample and among older (n=59) and younger adolescents (n=53). Among older but not younger adolescents, CAPS resulted in greater improvements on multiple dimensions of externalizing behavior problems than did IRC. Conclusion Online problem-solving therapy may be effective in reducing behavior problems in older adolescent survivors of moderate-severe TBI. PMID:23640543

Pelvic lymph node dissection (PLND) in prostate cancer is the most effective method for detecting lymph node metastases. However, a decline in the rate of PLND during radical prostatectomy (RP) has been noted. This is likely the result of prostate cancer stage migration in the prostate-specific antigen-screening era, and the introduction of minimally invasive approaches such as robot-assisted radical prostatectomy (RARP). To assess the efficacy, limitations, and complications of PLND during RARP. A review of the literature was performed using the Medline, Scopus, and Web of Science databases with no restriction of language from January 1990 to December 2012. The literature search used the following terms: prostate cancer, radical prostatectomy, robot-assisted, and lymph node dissection. The median value of nodal yield at PLND during RARP ranged from 3 to 24 nodes. As seen in open and laparoscopic RP series, the lymph node positivity rate increased with the extent of dissection during RARP. Overall, PLND-only related complications are rare. The most frequent complication after PLND is symptomatic pelvic lymphocele, with occurrence ranging from 0% to 8% of cases. The rate of PLND-associated grade 3-4 complications ranged from 0% to 5%. PLND is associated with increased operative time. Available data suggest equivalence of PLND between RARP and other surgical approaches in terms of nodal yield, node positivity, and intraoperative and postoperative complications. PLND during RARP can be performed effectively and safely. The overall number of nodes removed, the likelihood of node positivity, and the types and rates of complications of PLND are similar to pure laparoscopic and open retropubic procedures.

To describe the characteristics of hypophosphatemia in severely disabled individuals with neurological disorders and to identify its causative factors. We retrospectively reviewed clinical data from 82 individuals with motor skills classified as sitting, rollover or bedridden. Age, gender and body mass index were compared in individuals with (n=19) and without (n=63) a history of hypophosphatemia (serum phosphate levels refeeding syndrome (n=4) and Fanconi syndrome (n=3), but was unidentifiable in one episode. Significant elevations in C-reactive protein levels and reductions in sodium levels were observed during hypophosphatemia episodes. Hypophosphatemia is a common complication in severely disabled individuals with frequent bacterial infections, refeeding following malnutrition and valproate administration for epilepsy treatment. Because severe hypophosphatemia is life threatening, serum phosphate levels should be closely monitored in this population. Copyright © 2013 The Japanese Society of Child Neurology.

Full Text Available A 44-year-old man presenting to our hospital emergency room with abdominal pain was hospitalized for hyperlipidemic acute pancreatitis. A pig-tail catheter was placed percutaneously to drain an abscess on day 22. Although the abscess improved gradually and good clinical progress was seen, pancreatic duct disruption was strongly suspected and endoscopic retrograde cholangiopancreatography was performed on day 90. An endoscopic nasopancreatic drainage tube was placed, but even with concurrent use of a somatostatin analogue, treatment was ineffective. Surgical treatment was elected, but was subsequently postponed as the abscess culture was positive for extended-spectrum β-lactamase-producing Escherichia coli and methicillin-resistant Staphylococcus aureus. Drainage tubography showed a small fistula of the colon at the splenic flexure on day 140. Colonoscopy was performed on day 148. After indigo carmine had been injected, a fistula into the splenic flexure of the colon showed blue staining. The over-the-scope clip (OTSC system was used to seal the fistula and complete closure was shown. A liquid diet was started on day 159 and was smoothly upgraded to a full diet. Following removal of the pancreatic stent on day 180, drainage volume immediately decreased and the percutaneous drain was removed. On day 189, computed tomography showed no exacerbation of the abscess and the patient was discharged on day 194. This case of colonic fistula caused by severe acute pancreatitis was successfully treated using the OTSC system, avoiding the need for an open procedure.

Thyroid function abnormalities and thyroid autoantibodies have been frequently described in patients with systemic autoimmune diseases as systemic sclerosis (SSc). Serum TSH levels are higher in SSc patients with more severe skin diseases and a worse modified Rodnan skin score. Asymptomatic esophageal involvement due to SSc has never been described as a cause of severe hypothyroidism due to l-thyroxine (l-T4) malabsorption in patients with Hashimoto's thyroiditis (HT) and SSc. Here, we report a case of a 56-year-old female affected by both SSc and HT who developed severe hypothyroidism due to the loss of therapeutic efficacy of l-T4. Therapeutic failure resulted from the altered l-T4 absorption because of SSc esophageal complications. Clinical findings improved after the administration of oral liquid l-T4. Thyroid function completely normalized with a full clinical recovery, the disappearance of the pericardial effusion and the improvement of the pulmonary pressure. A recognition of a poor absorption is crucial in patients with hypothyroidism and SSc to reduce the risk of the subsequent adverse events. This case suggests the importance of clinical and laboratory surveillance in patients with SSc and HT because the systemic complications of these dysfunctions may worsen the prognosis of hypothyroid SSc/HT patients.

This chapter reviews the most common neurologic disorders associated with common vaccines, evaluates the data linking the disorder with the vaccine, and discusses the potential mechanism of disease. A literature search was conducted in PubMed using a combination of the following terms: vaccines, vaccination, immunization, and neurologic complications. Data were also gathered from publications of the American Academy of Pediatrics Committee on Infectious Diseases, the World Health Organization, the US Centers for Disease Control and Prevention, and the Vaccine Adverse Event Reporting System. Neurologic complications of vaccination are rare. Many associations have been asserted without objective data to support a causal relationship. Rarely, patients with a neurologic complication will have a poor outcome. However, most patients recover fully from the neurologic complication. Vaccinations have altered the landscape of infectious disease. However, perception of risk associated with vaccinations has limited the success of disease eradication measures. Neurologic complications can be severe, and can provoke fear in potential vaccines. Evaluating whether there is causal link between neurologic disorders and vaccinations, not just temporal association, is critical to addressing public misperception of risk of vaccination. Among the vaccines available today, the cost-benefit analysis of vaccinations and complications strongly argues in favor of vaccination. © 2014 Elsevier B.V. All rights reserved.

Idiopathic noncirrhotic portal hypertension is a heterogeneous group of diseases characterized by portal hypertension in the absence of cirrhosis. The efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in this population are unknown. The charts of patients with idiopathic noncirrhotic portal hypertension undergoing TIPS in seven centers between 2000 and 2014 were retrospectively reviewed. Forty-one patients were included. Indications for TIPS were recurrent variceal bleeding (n = 25) and refractory ascites (n = 16). Patients were categorized according to the presence (n = 27) or absence (n = 14) of significant extrahepatic comorbidities. Associated conditions were hematologic, prothrombotic, neoplastic, immune, and exposure to toxins. During follow-up (mean 27 ± 29 months), variceal rebleeding occurred in 7/25 (28%), including three with early thrombosis of the stent. Post-TIPS overt hepatic encephalopathy was present in 14 patients (34%). Eleven patients died, five due the liver disease or complications of the procedure and six because of the associated comorbidities. The procedure was complicated by hemoperitoneum in four patients (10%), which was fatal in one case. Serum creatinine (P = 0.005), ascites as indication for TIPS (P = 0.04), and the presence of significant comorbidities (P = 0.01) at the time of the procedure were associated with death. Mortality was higher in patients with significant comorbidities and creatinine ≥100 μmol/L (P portal hypertension who have normal kidney function or do not have severe extrahepatic conditions, TIPS is an excellent option to treat severe complications of portal hypertension.

Thoracic disc surgery can lead to a life-threatening complication: intracranial hypotension due to a subarachnoid-pleural fistula. We report a 63-year-old male with paraparesis due to multiple herniated thoracic discs, with compressive myelopathy. The patient required a circumferential procedure including a laminectomy/fusion followed by an anterior thoracic decompression to address both diffuse idiopathic skeletal hyperostosis (DISH) anteriorly and posterior stenosis. The postoperative course was complicated by severe intracranial hypotension attributed to the erroneous placement of a low-pressure drain placed in the pleural cavity instead of a lumbar drain; this resulted in subdural hematoma's necessitating subsequent surgery. Severe neurological deterioration occurring after thoracic decompressive surgery may rarely be attributed to intracranial hypotension due to a subarachnoid-pleural fistula. Patients should be treated with external lumbar drainage of cerebrospinal fluid for 3-5 days rather than a low-pressure pleural drain to avoid the onset of intracranial hypotension leading to symptomatic subdural hematomas.

Extracorporeal shock wave lithotripsy (ESWL) has evolved as a standard treatment modality for calculi of the upper urinary tract. Noninvasive ESWL shows rare life-threatening complications. Herein we have reported the case of a liver transplant recipient who developed severe renal hemorrhage after ESWL of a renal calculus. Transfusion of erythrocytes and platelets led to anaphylactic shock with acute renal failure requiring intensive care. The patient fully recovered shortly thereafter and was discharged home with a residual left kidney stone measuring 8 mm. A 55-year-old man with a single left kidney underwent ESWL due to symptomatic left nephrolithiasis. He had undergone successful liver transplantation 11 years earlier. At the time of ESWL his liver functions were normal and his serum creatinine level was 1.3 mg/dL. Two weeks before the treatment a double pigtail ureteral stent was inserted because of a symptomatic left hydronephrosis. Several hours after ESWL treatment the patient complained of left-sided flank pain. An ultrasound revealed a large subcapsular hematoma of the left kidney, which was confirmed using abdominal computed tomography (CT). With the patient being hemodynamically stable, we opted for conservative management. Despite postinterventional complications, the patient made a fast recovery. ESWL is a noninvasive, safe, and efficient method to treat renal calculi. Patients who are at risk for hemorrhage should undergo close postinterventional monitoring, including red blood cell count and renal ultrasound. Copyright © 2010 Elsevier Inc. All rights reserved.

Introduction: The kidneys connective tissue condition in the antenatal period affects the formation of tissues and it changes with the development of various general pathological processes in this organ. The aim of the study was to identify the morphological features of kidneys connective tissue of fetuses and newborns from mothers whose pregnancy was complicated by preeclampsia of varying degrees of severity. Materials and methods: The material of the study was the tissue of kidneys of mature fetuses and newborns from mothers with physiological pregnancy (28 cases), as well as from mothers whose pregnancy was complicated by preeclampsia of varying degrees of severity (78 cases). Immunohistochemical study was performed by an indirect Coons method according to M. Brosman's technique using monoclonal antibodies to collagen type I, III and IV. Results: The kidneys connective tissue of fetuses and newborns developing under the maternal preeclampsia conditions is characterized by the qualitative and quantitative changes that indicate the development of sclerotic processes in this organ, the severity of which increase with the age and with the increase of the maternal preeclampsia severity. Qualitative changes are characterized by an increase of the fibrous component, thickening of the bundles of connective tissue fibers, and a decrease in the distance between them. Quantitative changes are characterized by a pronounced predominance of collagen fibers over elastic fibers, almost total absence in some field of view elastic fibers and the violation of the content of collagen type I, III and IV. Conclusion: Maternal preeclampsia underlies the development of qualitative and quantitative changes in kidneys connective tissue of fetuses and newborns, which as a result will lead to disruption of the functions of these organs in such children.

The objective of this work is to report our experience with (131)I therapy without recent antithyroid drug (ATD) pretreatment for refractory severe hyperthyroidism complicated by hyperbilirubinemia due to hepatic dysfunction. Five patients with refractory severe hyperthyroidism were treated with (131)I at 90 to 120 μCi/g-thyroid (total activity, 6.2 to 10.1 mCi). The patients previously had received ATD treatment from 2 months to 12 years and discontinued ATDs from 2 months to 4 years before (131)I treatment due to treatment failure or severe jaundice. Prior to (131)I therapy, the patients were asked to take a low-iodine diet and were treated with bisoprolol fumarate, digoxin, furosemide, S-adenosylmethionine, polyene phosphatidylcholine, and plasma exchange as supportive treatment for related clinical conditions. Four of the patients also received lithium carbonate in conjunction with their (131)I treatment. The patients were followed for 4 to 9 years after (131)I therapy. After (131)I treatment, jaundice disappeared completely within 3 to 4 months in all patients, and liver function tests returned to normal. Concurrent atrial fibrillation and heart failure, leukopenia and thrombocytopenia, or thrombocytopenia and left cardiac enlargement improved remarkably in 3 patients during the follow-up period. Three to 45 months after (131)I treatment, hypothyroidism was noted in the patients and they were treated with L-thyroxine replacement therapy. (131)I therapy without recent ATD pretreatment for refractory severe hyperthyroidism complicated by serious jaundice appears to be safe and effective, with good long-term results. It may be the preferred therapy for such patients and should be used as early as possible.

A 4-year-old patient, who presented with an immediate orbital haematoma as a result of a subtenon injection of triamcinolone in the trochlear region of the right eye on finishing a surgical procedure for Brown's syndrome. After one week, when it could be examined better, the presence of a cherry red spot was observed due to the embolisation of the central artery of the retina by triamcinolone crystals. Triamcinolone is an anti-inflammatory drug currently used in Ophthalmology for the treatment of various conditions. Although exceptional, it has been described that its use may provoke embolisations due to the entry of the steroid into the circulation. Copyright © 2015 Sociedad Española de Oftalmología.

Severe obesity is the only obesity classification increasing in prevalence among children and adolescents. Treatment options that produce meaningful and sustained weight loss and comorbidity resolution are urgently needed. The purpose of this review is to provide a brief overview of the current treatment options for pediatric severe obesity and offer suggestions regarding future opportunities for accelerating the development and evaluation of innovative treatment strategies. At present, there are three treatment options for youth with severe obesity: lifestyle modification therapy, pharmacotherapy, and bariatric surgery. Lifestyle modification therapy can be useful for improving many chronic disease risk factors and comorbid conditions but often fails to achieve clinically meaningful and sustainable weight loss. Pharmacotherapy holds promise as an effective adjunctive treatment but remains in the primordial stages of development in the pediatric population. Bariatric surgery provides robust weight loss and risk factor/comorbidity improvements but is accompanied by higher risks and lower uptake compared to lifestyle modification therapy and pharmacotherapy. New areas worth pursuing include combination pharmacotherapy, device therapy, identification of predictors of response aimed at precision treatment, and interventions in the postbariatric surgical setting to improve long-term outcomes. Treating pediatric severe obesity effectively and safely is extremely challenging. Some progress has been made, but substantially more effort and innovation are needed in the future to combat this serious and ongoing medical and public health issue. © 2018 The Obesity Society.

Abstract The effects of rickets on children recovery from severe acute malnutrition (SAM) are unknown. Rickets may affect both growth and susceptibility to infectious diseases. We investigated the associations of clinically diagnosed rickets with life‐threatening events and anthropometric recovery during 1 year following inpatient treatment for complicated SAM. This was a secondary analysis of clinical trial data among non‐human immunodeficiency virus‐infected Kenyan children with complicated SAM (2–59 months) followed for 1 year posthospital discharge (ClinicalTrials.gov ID NCT00934492). The outcomes were mortality, hospital readmissions, and growth during 12 months. The main exposure was clinically diagnosed rickets at baseline. Of 1,778 children recruited, 230 (12.9%, 95% CI [11.4, 14 .6]) had clinical signs of rickets at baseline. Enrolment at an urban site, height‐for‐age and head circumference‐for‐age z scores were associated with rickets. Rickets at study enrolment was associated with increased mortality (adjusted Hazard Ratio [aHR] 1.61, 95% CI [1.14, 2.27]), any readmission (aHR 1.37, 95% CI [1.09, 1.72]), readmission for severe pneumonia (aHR 1.37, 95% CI [1.05, 1.79]), but not readmission with diarrhoea (aHR 1.05, 95% CI [0.73, 1.51]). Rickets was associated with increased height gain (centimetres), adjusted regression coefficient 0.19 (95% CI [0.10, 0.28]), but not changes in head circumference, mid‐upper arm circumference, or weight. Rickets was common among children with SAM at urban sites and associated with increased risks of severe pneumonia and death. Increased height gain may have resulted from vitamin D and calcium treatment. Future work should explore possibility of other concurrent micronutrient deficiencies and optimal treatment of rickets in this high‐risk population. PMID:29178404

The California Technology Assessment Forum is dedicated to assessment and public reporting of syntheses of available data on medical technologies. In this assessment, transcatheter aortic valve replacement (TAVR) was evaluated for patients with severe aortic stenosis (AS) who are at high risk for complications. In this assessment, 5 criteria were used: Regulatory approval, sufficient scientific evidence to allow conclusions on effectiveness, evidence that the technology improves net health outcomes, evidence that the technology is as beneficial as established methods, and availability of the technology outside investigational settings. In this assessment, all 5 criteria were judged to have been met. The primary benefit of TAVR is the ability to treat AS in patients who would otherwise be ineligible for surgical aortic valve replacement. It may also be useful for patients at high surgical risk by potentially reducing periprocedural complications and avoiding the morbidity and recovery from undergoing heart surgery. Potential harms include the need for conversion to an open procedure, perioperative death, myocardial infarction, stroke, bleeding, valve embolization, aortic regurgitation, heart block that requires a permanent pacemaker, renal failure, pulmonary failure, and major vascular complications such as cardiac perforation or arterial dissection. Potential long-term harms include death, stroke, valve failure or clotting, and endocarditis. As highlighted at the February 2012 California Technology Assessment Forum meeting, the dispersion of this technology to new centers across the United States must proceed with careful thought given to training and proctoring multidisciplinary teams to become new centers of excellence. TAVR is a potentially lifesaving procedure that may improve quality of life for patients at high risk for surgical AVR. However, attention needs to be paid to appropriate patient selection, their preoperative evaluation, surgical techniques, and
Full Text Available BACKGROUND To compare serum Lactate Dehydrogenase (LDH and serum Aspartate Transaminase (AST of normotensive pregnant women with those of preeclamptic and eclamptic women. To determine the relationship of levels of serum lactate dehydrogenase and serum aspartate transaminase with severity of pregnancy-induced hypertension and its complications. MATERIALSAND METHODS The study was carried out on pregnant hypertensive patients attending outpatient department of Obstetrics and Gynaecology department, AMCH, Dibrugarh, Assam from 1 st July 2013 to 30 th June 2014. Normotensive pregnant women were taken as controls. Each serum sample from both the control group as well as study group was estimated for lactate dehydrogenase and aspartate transaminase using standard methods and a comparison is drawn and analysed using t-test and Chi-square test. RESULTS Serum lactate dehydrogenase and serum aspartate transaminase levels were higher in the study group in comparison to the study groups. The mean serum LDH was 198±30.03U/L in control group, whereas in preeclampsia and eclampsia, mean serum levels of LDH were 817±114U/L and 927±108U/L, respectively. The levels of the serum AST were found to be less than 600U/L in normotensive and preeclampsia patients and more than 600 U/L in eclampsia and other complications of PIH. CONCLUSION Serum lactate dehydrogenase and serum aspartate transaminase levels in patients suffering from preeclampsia and its complications are consistently higher compared to the normotensive pregnant patients. To determine the usefulness of inclusion of these enzymes along with other cardiac enzymes in the panel of investigations of pregnant women universally needs further large scale comparative studies.

The mumps vaccine (Jeryl-Lynn-strain) was introduced in Spain in 1981, and a vaccination policy which included a second dose was added in 1995. From 1992-1999, a Rubini-strain based vaccine was administered in many regions but later withdrawn due to lack of effectiveness. Despite high levels of vaccination coverage, epidemics have continued to appear. We characterized the three epidemic waves of mumps between 1998 and 2014, identifying major changes in susceptible populations using Poisson regression. For the period 1998-2003 (P1), the most affected group was from 1 to 4years old (y) [Incidence Rate (IR)=71.7 cases/100,000 population]; in the periods 2004-2009 (P2) and 2010-2014 (P3) IR ratio (IRR) increased among 15-24y (P2=1.46; P3=2.68) and 25-34y (P2=2.17; P3=4.05). Hospitalization rate (HR), complication rate (CR) and neurological complication rate (NR) among hospitalized subjects decreased across the epidemics, except for 25-34y which increased: HR ratio (HRR) (P2=2.18; P3=2.16), CRR (P3=2.48), NRR (P3=2.41). In Spain mumps incidence increased, while an overall decrease of hospitalizations and severe complications occurred across the epidemics. Cohorts born during periods of low vaccination coverage and those vaccinated with Rubini-strain were the most affected populations, leading to a shift in mumps cases from children to adolescents and young adults; this also reveals the waning immunity provided by the mumps vaccine. Despite not preventing all mumps cases, the vaccine appears to prevent serious forms of the disease. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

It is unclear whether the frequent non-severe episodes of hypoglycaemia observed during intensive glucose control in individuals with type 1 diabetes (T1D) are associated with subsequent weight gain. We analysed the association between non-severe hypoglycaemia and weight gain in 1441 Diabetes Control and Complication Trial (DCCT) participants. Non-severe hypoglycaemia was assessed by hypo-score (ie, number of blood glucose values gain. The annual weight gain by hypo-score tertiles was 0.8 ± 1.2 (T1), 1.3 ± 1.5 (T2) and 1.4 ± 1.3 kg/y (T3), P gain of 1.8 kg/y was 2.14 (95% CI, 1.56-2.93) for T2, and 2.53 (95%CI, 1.85-3.45) for T3 vs T1. These differences in weight gain and in risk of weight gain remained significant after adjustment for sex, age, duration of diabetes, HbA1c at baseline and treatment arms. In conclusion, our analysis shows a significant association between non-severe hypoglycaemia and weight gain in individuals with T1D from the DCCT. © 2017 John Wiley & Sons Ltd.
Due to the defense in depth concept and redundancy in safety systems utilized, complex industrial plants, such as nuclear power plants (NPPs) can be operated safely. This capability has been demonstrated by many years of safe operation by numerous NPPs in the US and abroad. However, the occurrence of severe accidents has also demonstrated that constant vigilance in a number of areas is necessary to ensure continued safe operation. The areas noted as particularly important are Design, Organization and Management, Maintenance, and Operations (Human Performance). 18 refs

To develop a software that can be used to standardize optical density to normalize the procedures and results of standardization in order to effectively solve several problems generated during standardization of in-direct ELISA results. The software was designed based on the I-STOD method with operation settings to solve the problems that one might encounter during the standardization. Matlab GUI was used as a tool for the development. The software was tested with the results of the detection of sera of persons from schistosomiasis japonica endemic areas. I-STOD V1.0 (WINDOWS XP/WIN 7, 0.5 GB) was successfully developed to standardize optical density. A serial of serum samples from schistosomiasis japonica endemic areas were used to examine the operational effects of I-STOD V1.0 software. The results indicated that the software successfully overcame several problems including reliability of standard curve, applicable scope of samples and determination of dilution for samples outside the scope, so that I-STOD was performed more conveniently and the results of standardization were more consistent. I-STOD V1.0 is a professional software based on I-STOD. It can be easily operated and can effectively standardize the testing results of in-direct ELISA.

Advances in critical care medicine have made it possible to sustain vital organ systems in brain-dead patients. One clinical scenario besides donor organ retrieval in which a benefit may be gained from continuing life support is pregnancy. A pregnant woman in her late 30's at 23 weeks gestation exhibiting worsening depression was referred to the Department of Psychiatry. One day after admission she attempted suicide by hanging and suffered a cardiopulmonary arrest. A fetal heart beat and fetal motion was confirmed immediately after resuscitation. Three days after admission, an emergency Cesarean section (CS) was performed because of her unstable hemodynamic situation. The baby was born and the mother died after delivery. The baby presented neurological complications. Such a case should be managed collaboratively among professional experts in several medical teams. Consensus and recommendations for the management of similar scenarios may also be adjusted.

The treatment of tibial plafond fractures is challenging to foot and ankle surgeons. Open reduction and internal fixation and limited internal fixation combined with an external fixator are 2 of the most commonly used methods of tibial plafond fracture repair. However, conclusions regarding the superior choice remain controversial. The present meta-analysis aimed to quantitatively compare the postoperative complications between open reduction and internal fixation and limited internal fixation combined with an external fixator for tibial plafond fractures. Nine studies with 498 fractures in 494 patients were included in the present study. The meta-analysis found no significant differences in bone healing complications (risk ratio [RR] 1.17, 95% confidence interval [CI] 0.68 to 2.01, p = .58], nonunion (RR 1.09, 95% CI 0.51 to 2.36, p = .82), malunion or delayed union (RR 1.24, 95% CI 0.57 to 2.69, p = .59), superficial (RR 1.56, 95% CI 0.43 to 5.61, p = .50) and deep (RR 1.89, 95% CI 0.62 to 5.80) infections, arthritis symptoms (RR 1.20, 95% CI 0.92 to 1.58, p = .18), or chronic osteomyelitis (RR 0.31, 95% CI 0.05 to 1.84, p = .20) between the 2 groups.

The local failure strains of essential reactor vessel components are investigated. The size influence of the components is of special interest. Typical severe accident conditions including elevated temperatures and dynamic loads are considered. The main part of work consists of test families with specimens under uniaxial and biaxial static and dynamic loads. Within one test family the specimen geometries and the load conditions are similar, the temperature is the same; but the size is varied up to reactor dimensions. Special attention is given to geometries with a hole or a notch causing non-uniform stress and strain distributions typical for reactor components. There are indications that for such non-uniform distributions size effects may be stronger than for uniform distributions. Thus size effects on the failure strains and failure processes are determined under realistic conditions. Several tests with nominal identical parameters are performed for small size specimens. In this way some information is obtained about the scatter. A reduced number of tests is carried out for medium size specimens and only a few tests are carried out for large size specimens to reduce the costs to an acceptable level. To manufacture all specimens sufficient material was available from the unused reactor pressure vessel Biblis C consisting of the material 22NiMoCr37. Thus variations of the mechanical material properties, which could impair the interpretation of the test results, are quite small. This has been confirmed by an adequate number of additional quality assurance tests. A key problem was the definition of failure and the determination of the local strains at failure for very different specimens under varying load conditions. Here appropriate methods had to be developed including the so-called 'vanishing gap method' and the 'forging die method'. They are based on post test geometrical measurements of the fracture surfaces and reconstructions of the related strain fields

Incisor trauma is common in children, and can cause severe complications during adolescent growth and development. This report describes the treatment of a 16-year-old patient with severe anterior open bite due to ankylosis of the maxillary left incisor after dental trauma as an 8-year-old. No examination or active treatment was undertaken until he was 16 years old. Clinical examination revealed that the maxillary left incisor was severely intruded accompanied by a vertical alveolar bone defect. Orthodontic treatment combined with surgical luxation took 3 years and 7 months. During treatment, the intruded incisor was moved to the occlusal level and the alveolar bone defect was restored, achieving normal occlusion. After two years of retention, the maxillary left incisor was retained in a stable normal position with a slightly reduced overbite. This case demonstrates that surgical luxation with orthodontic traction can be an effective approach, especially when the ankylosed tooth has a single root. Long-term monitoring of orthodontic stability and the maintenance of periodontal health are crucial in the post-treatment period.

Patients with self-limited statin-related myopathy improve spontaneously when statins are stopped. In contrast, patients with statin-associated autoimmune myopathy have autoantibodies recognizing 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGCR) and usually require immunosuppressive therapy to control their disease. On initial presentation, it can sometimes be difficult to distinguish between these 2 diseases, as both present with muscle pain, weakness, and elevated serum creatine kinase (CK) levels. The goal of this study was to determine whether patients with severe self-limited statin-related myopathy also make anti-HMGCR autoantibodies. We screened 101 subjects with severe self-limited cerivastatin-related myopathy for anti-HMGCR autoantibodies. No patient with severe self-limited cerivastatin-related myopathy had anti-HMGCR autoantibodies. Anti-HMGCR autoantibody testing can be used to help differentiate whether a patient has self-limited myopathy due to cerivastatin or autoimmune statin-associated myopathy; these findings may apply to other statins as well.

They are based on post test geometrical measurements of the fracture surfaces and reconstructions of the related strain fields using finite element calculations, for instance. To deepen the understanding of structural degradation and fracture and to allow extrapolations, advanced computational methods including damage models have been developed and validated. Several approaches were tried in parallel including so-called non-local concepts and descriptions of stochastic properties at grain size level. The experimental results indicate that stresses versus dimensionless deformations are approximately size independent up to failure for specimens of similar geometry under similar load conditions. Also the maximum stress is approximately size independent, if failure occurs after the maximum stress is reached

Our goal is to determine how the stress of infections alters the adaptation to reduced food intake in children. We think that an important element is the need for hepatic synthesis of rapidly turning over acute-phase proteins, a critical factor in overall maintenance of host defenses. When the child's prior intake has been adequate, even though growth may temporarily cease, the presence of adequate amino acid stores in tissues allows the hepatic response to stress to be maintained at the same time as an adequate rate of synthesis of nutrient transport proteins. However, when the immune system is activated in a children whose nutrition is already suboptimal the ability of the liver to synthesize nutrient transport proteins is compromised thereby further impeding nutrient utilization. We will use stable isotope tracer methodology to determine the effects of severe protein energy malnutrition, with and without infection, on the rates of synthesis of nutrient transport proteins and acute-phase proteins in undernourished children at three time points during treatment; in the early resuscitative period, after appetite has returned, and at the end of the catch-up growth phase when normal growth has resumed.

Full Text Available OBJECTIVE: Veno-venous extracorporeal oxygenation for respiratory support has emerged as a rescue alternative for patients with hypoxemia. However, in some patients with more severe lung injury, extracorporeal support fails to restore arterial oxygenation. Based on four clinical vignettes, the aims of this article were to describe the pathophysiology of this concerning problem and to discuss possibilities for hypoxemia resolution. METHODS: Considering the main reasons and rationale for hypoxemia during veno-venous extracorporeal membrane oxygenation, some possible bedside solutions must be considered: 1 optimization of extracorporeal membrane oxygenation blood flow; 2 identification of recirculation and cannula repositioning if necessary; 3 optimization of residual lung function and consideration of blood transfusion; 4 diagnosis of oxygenator dysfunction and consideration of its replacement; and finally 5 optimization of the ratio of extracorporeal membrane oxygenation blood flow to cardiac output, based on the reduction of cardiac output. CONCLUSION: Therefore, based on the pathophysiology of hypoxemia during veno-venous extracorporeal oxygenation support, we propose a stepwise approach to help guide specific interventions.

Children with complicated severe acute malnutrition (SAM) have a greatly increased risk of mortality from infections while in hospital and after discharge. In HIV-infected children, mortality and admission to hospital are prevented by daily co-trimoxazole prophylaxis, despite locally reported bacterial resistance to co-trimoxazole. We aimed to assess the efficacy of daily co-trimoxazole prophylaxis on survival in children without HIV being treated for complicated SAM. We did a multicentre, double-blind, randomised, placebo-controlled study in four hospitals in Kenya (two rural hospitals in Kilifi and Malindi, and two urban hospitals in Mombasa and Nairobi) with children aged 60 days to 59 months without HIV admitted to hospital and diagnosed with SAM. We randomly assigned eligible participants (1:1) to 6 months of either daily oral co-trimoxazole prophylaxis (given as water-dispersible tablets; 120 mg per day for age malnutrition (kwashiorkor), and 1221 (69%) were stunted (length-for-age Z score child-years of observation, 122 (14%) of 887 children in the co-trimoxazole group died, compared with 135 (15%) of 891 in the placebo group (unadjusted hazard ratio [HR] 0·90, 95% CI 0·71-1·16, p=0·429; 16·0 vs 17·7 events per 100 child-years observed (CYO); difference -1·7 events per 100 CYO, 95% CI -5·8 to 2·4]). In the first 6 months of the study (while participants received study medication), 63 suspected grade 3 or 4 associated adverse events were recorded among 57 (3%) children; 31 (2%) in the co-trimoxazole group and 32 (2%) in the placebo group (incidence rate ratio 0·98, 95% CI 0·58-1·65). The most common adverse events of these grades were urticarial rash (grade 3, equally common in both groups), neutropenia (grade 4, more common in the co-trimoxazole group), and anaemia (both grades equally common in both groups). One child in the placebo group had fatal toxic epidermal necrolysis with concurrent Pseudomonas aeruginosa bacteraemia. Daily co

To investigate the effects of lung protective ventilation strategy combined with lung recruitment maneuver on ARDS complicating patients with severe burn. Clinical data of 15 severely burned patients with ARDS admitted to our burn ICU from September 2011 to September 2013 and conforming to the study criteria were analyzed. Right after the diagnosis of acute lung injury/ARDS, patients received mechanical ventilation with lung protective ventilation strategy. When the oxygenation index (OI) was below or equal to 200 mmHg (1 mmHg = 0. 133 kPa), lung recruitment maneuver was performed combining incremental positive end-expiratory pressure. When OI was above 200 mmHg, lung recruitment maneuver was stopped and ventilation with lung protective ventilation strategy was continued. When OI was above 300 mmHg, mechanical ventilation was stopped. Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, variables of blood gas analysis (pH, PaO2, and PaCO2) were obtained by blood gas analyzer, and the OI values were calculated; hemodynamic parameters including heart rate, mean arterial pressure (MAP), central venous pressure (CVP) of all patients and the cardiac output (CO), extravascular lung water index (EVLWI) of 4 patients who received pulse contour cardiac output (PiCCO) monitoring were monitored. Treatment measures and outcome of patients were recorded. Data were processed with analysis of variance of repeated measurement of a single group and LSD test. (1) Before combining lung recruitment maneuver, 24 h after combining lung recruitment maneuver, and at the end of combining lung recruitment maneuver, the levels of PaO2 and OI of patients were respectively (77 ± 8), (113 ± 5), (142 ± 6) mmHg, and (128 ± 12), (188 ± 8), (237 ± 10) mmHg. As a whole, levels of PaO2 and OI changed significantly at different time points (with F values respectively 860. 96 and 842. 09, P values below

Dengue is associated with many neurological dysfunctions. Up to 4% of dengue patients may develop neuromuscular complications. Muscle involvement can manifest with myalgias, myositis, rhabdomyolysis and hypokalemic paralysis. Diffuse myalgia is the most characteristic neurological symptom of dengue fever. Dengue-associated myositis can be of varying severity ranging from self-limiting muscle involvement to severe dengue myositis. Dengue-associated hypokalemic paralysis often has a rapidly evo...

Macular peeling refers to the surgical technique for the removal of preretinal tissue or the internal limiting membrane (ILM) in the macula for several retinal disorders, ranging from epiretinal membranes (primary or secondary to diabetic retinopathy, retinal detachment…) to full-thickness macular holes, macular edema, foveal retinoschisis, and others. The technique has evolved in the last two decades, and the different instrumentations and adjuncts have progressively advanced turning into a safer, easier, and more useful tool for the vitreoretinal surgeon. Here, we describe the main milestones of macular peeling, drawing attention to its associated complications. PMID:26425351

Introduction Cetuximab-based chemotherapy showed a statistically significantly higher response rate compared with chemotherapy such as FOLFOX. Therefore, FOLFOX plus cetuximab is suspected to be the best regimen to alleviate tumor-related symptoms with a high response rate. Case Report Here we present the results of 8 consecutive patients with metastatic colorectal cancer with poor performance status and/or severe complications who were treated with first-line FOLFOX with cetuximab. Six of 8 patients achieved an apparent clinical benefit, including radiological response and symptoms improvement. Two patients with BRAF mutation could achieve neither clinical benefit nor radiological response. Conclusion Although an optimal line of therapy with cetuximab is unclear yet with bevacizumab in mind, we propose that patients who need a tumor response to alleviate their symptoms due to advanced disease might be candidates for first-line cetuximab-based therapy as shown in our cases. Additionally, patients with BRAF mutant tumors might be important candidates for novel targeted therapy in the future to improve their poor prognosis. PMID:21347194

Since 2000, we adopted mild hypothermia of the present cooling protocol for 3 days at 34-35 degrees to improve outcomes of patients with severe traumatic brain injury (TBI). In the present study, we evaluated the efficacy and safety of this protocol retrospectively. Between 2000 and 2008, a total of 35 patients with severe TBI, 16 to 69 years of age, were enrolled. The initial Glasgow Coma Scale scores (GCS) of all patients ranged from 3 to 13, but many patients' GCS fell down immediately to under 5. All patients had intracranial mass lesions and brain swelling with significant midline shift and underwent hematoma removal operations and craniectomies (subdural hematoma (SDH) 22 cases, contusion 6 and bilateral brain swelling 7). Mild hypothermia was induced by surface cooling and continued 3 days at 34-35degC. Then, the patients were rewarmed at a rate 0.5degC/day. The Glasgow Outcome Scale at discharge indicated that 20 cases had a favorable outcome (57%) and the mortality rate was 20% in all patients. No patient had severe septic complication during the therapy. We found that this protocol did not improve the prognoses of patients aged 51 years and above, those with higher intracranial pressure (ICP) than 30 mmHg immediately after surgery and those with large contusion and diffuse axonal injury (DAI) findings on CT. Also subdural hematomas thicker than 18 mm and midline shift of greater than 16 mm on CT were predictive of a poor outcome. The GCS on admission, the presence of pupillary abnormalities were not predictable factors of outcome. Cerebral blood flow (CBF) and cerebral metabolic rate of oxygen (CMRO 2 ) values measured immediately after operations by Xenon-CT, predicted accurately unfavorable outcome. Based on these findings, hypothermia therapy of the present protocol are safe and effective and the age, initial ICP, findings of initial damage and thickness of subdural hematomas or midline shift on CT are predictive factors of outcomes.

Full Text Available Despite advances in technology, ventricular assist devices still experience a number of complications limiting their long-term use. We present a 73-year-old woman implanted with a left ventricular assist device (LVAD five years prior due to end-stage dilated cardiomyopathy, who died several weeks after admission to the hospital. Post-mortem examination revealed a large obstructing pannus in the LVAD inflow. As a result of increased LVAD use, complications such as infection, device thrombosis and pannus must be promptly recognized and managed appropriately to ensure the greatest chance of patient survival.

Late presentation and ineffective phototherapy account for excessive rates of avoidable exchange transfusions (ETs) in many low- and middle-income countries. Several system-based constraints sometimes limit the ability to provide timely ETs for all infants at risk of kernicterus, thus necessitating a treatment triage to optimize available resources. This article proposes a practical priority-setting model for term and near-term infants requiring ET after the first 48 h of life. The proposed model combines plasma/serum bilirubin estimation, clinical signs of acute bilirubin encephalopathy and neurotoxicity risk factors for predicting the risk of kernicterus based on available evidence in the literature.

Infected pancreatic necrosis (IPN) is one of the most severe complications of acute pancreatitis (AP). Sequential surgical debridement represents one of the most effective treatments in terms of morbidity and mortality. The aim of this paper is to describe the quality of life and long-term results (e.g., nutritional, muscular, and pancreatic function) of patients treated by sequential necrosectomy at the Department of Surgery of the University of Insubria (Varese, Italy). Data were collected on patients undergoing sequential surgical debridement as treatment for IPN. The severity of AP was evaluated using the Ranson criteria, the Acute Physiology and Chronic Health Evaluation (APACHE II) Score, and the Sepsis Score, as well as the extent of necrosis. The surgical approach was through a midline or subcostal laparotomy, followed by exploration of the peritoneal cavity, wide debridement, and peritoneal lavage. The abdomen was either left open or closed partially with a surgical zipper, with multiple re-laparotomies scheduled until debridement of necrotic tissue was complete. The long-term evaluation focused on late morbidity, performance status, and abdominal wall function. In the majority of patients (68%), mixed flora were isolated. Pseudomonas aeruginosa was the microorganism identified most commonly (59%), often associated with Candida albicans or C. glabrata. The mean total hospital stay was 71+/-38 days (range 13-146 days), of which 24+/-19 days (range 0-66 days) were in the intensive care unit. Eight patients died, the deaths being caused by multiple organ dysfunction syndrome in seven patients and hemorrhage from the splenic artery in one. Normal exocrine and endocrine pancreatic function was observed in 28 patients (88%). At discharge, four patients had steatorrhea, which was temporary. Eight patients (23%) developed pancreatic pseudocysts, and in six, cystogastostomy was performed. Most patients (29/32, 91%) developed a post-operative hernia, but only five

To explore the relationships between periodontitis and microvascular complications as well as glycemic control in type 2 diabetes patients. This multicenter, hospital-based, cross-sectional study included 620 patients with type 2 diabetes. We compared the prevalence and severity of periodontitis between patients with ≥1 microvascular complication and those without microvascular complications. We also compared the prevalence and severity of periodontitis among patients with different degrees of glycemic control. After adjusting for confounding factors, multiple logistic regression analysis showed that the severity of periodontitis was significantly associated with the number of microvascular complications (odds ratio 1.3, 95% confidence interval 1.1-1.6), glycated hemoglobin ≥8.0% (64 mmol/mol; odds ratio 1.6; 95% confidence interval 1.1-2.3), and older age (≥50 years; odds ratio 1.7; 95% confidence interval 1.1-2.6). However, the prevalence of periodontitis was not significantly associated with the number of microvascular complications, but was associated with male sex, high glycated hemoglobin (≥8.0% [64 mmol/mol]), older age (≥40 years), longer duration of diabetes (≥15 years) and fewer teeth (≤25). Furthermore, propensity score matching for age, sex, diabetes duration and glycated hemoglobin showed that the incidence of severe periodontitis was significantly higher among patients with microvascular complications than among those without microvascular complications (P periodontitis in patients with type 2 diabetes, whereas poor glycemic control is a risk factor for increased prevalence and severity of periodontitis. © 2017 The Authors.

To determine if a pre-operative group rehabilitation programme can improve arthritis self-efficacy for people with severe hip and knee osteoarthritis. Single group, repeated measures design: 4-week baseline phase followed by a 6-week intervention phase of water exercise, and education with self-management strategies. The primary outcome was arthritis self-efficacy. The secondary outcomes were measures of pain (WOMAC), activity limitation (WOMAC), activity performance (30 s chair stand test, 10 m walk test) and health-related quality of life (EuroQol). Twenty participants (10 knee osteoarthritis and 10 hip osteoarthritis) with a mean age of 71 years (SD 7) attended 92% (SD 10%) of the scheduled sessions. All measures demonstrated baseline stability between two time points for measurements at week 1 and measurements at week 4. After the 6-week intervention programme there were no significant improvements for arthritis self-efficacy. There was a 12% increase for fast walking speed (mean increase of 0.14 m/s, 95% CI 0.07, 0.22). There were no significant improvements for other secondary outcomes. A pre-operative water-based exercise and educational programme did not improve arthritis self-efficacy, self-reported pain and activity limitation, and health-related quality of life for people with hip and knee osteoarthritis who were candidates for joint replacement. While there was a significant increase in one measure of activity performance (walking speed), these findings suggest the current programme may be of little value. Implications for Rehabilitation This pre-operative group rehabilitation programme for people with severe hip and knee osteoarthritis did not change arthritis self-efficacy, pain, activity limitation and health-related quality of life. This programme may have little value in preparing people for joint replacement surgery. The optimal pre-operative programme requires further design and investigation.

AL was defined as forced expiratory volume in 1 second/forced vital capacity of <0.7. Workers completed a questionnaire on productivity loss at work and sick leave. The quality and quantity of productivity loss at work were measured on a ten-point scale indicating how much work was actually performed on the previous workday. Participants were asked how many days in the past 12 months they were unable to work because of health problems. Logistic regression analysis was used to assess the associations between AL severity and the quality and quantity of productivity loss at work as well as use of sick leave.Results: Compared with workers without AL, workers with moderate-to-severe AL showed a significant productivity loss (quality: odds ratio [OR] =2.04, 95% confidence interval [CI]: 1.12–3.71, P=0.02 and quantity: OR =2.19, 95% CI: 1.20–4.00, P=0.011 and use of sick leave (OR =2.69, 95% CI: 1.33–5.44, P=0.006 after adjusting for sex, age, body mass index, smoking status, hypertension, hyperglycemia, dyslipidemia, sleep duration, work hours per day, and workplace smoking environment.Conclusion: AL severity was significantly associated with work productivity loss and use

A retrospective analysis of late rectal and recto-sigmoid complications was carried out of the 203 patients with stage III B carcinoma of uterine cervix, treated using radiation therapy alone during January 1979 to December 1983. The patients were treated with a combination of external irradiation and single intracavitary insertion. External irradiation was randomised to one of the four different fractionation regimes having dose per fraction of 2 Gy, 3 Gy, 4 Gy and 5.4 Gy, delivering with five fractions/week, three fractions/week, two fractions/week and one fraction/week, respectively. The total doses in four different regimens were adjusted using the TDF model. There were 39 cases of late radiation induced rectal and recto-sigmoid complications. The complication rate was correlated with the dose per fraction and TDFs delivered in each regimen. The complication rate of 8.2% for 2 Gy per fraction was increased to 33.33% for 5.4 Gy per fraction. It was found that there is strong correlation (P [de

In the event of hypothetical severe accidents in light-water reactors, considerable amounts of hydrogen may be produced and released into the containment. Combustion of the hydrogen may jeopardize the integrity of the containment. The study reported here aimed to identify methods to mitigate the hydrogen problem. These methods should either prevent hydrogen combustion, or limit its effects. The following methods have been investigated: pre-inerting; chemical oxygen absorption; removal of oxygen by combustion; post-inerting with N 2 , CO 2 , or halon; aqueous foam; water fog; deliberate ignition; containment purging; and containment venting. The present state of the art in both nuclear and non-nuclear facilities, has been identified. The assessment of the methods was based on accident scenarios assuming significant release of hydrogen and the spectrum of requirements derived from these scenarios was used to determine the advantages and drawbacks of the various methods, assuming their application in a pressurized water reactor of German design.

Full Text Available Phytate is not only an unavailable source of phosphorus (P for broilers but it also acts as an anti-nutrient, reducing protein and mineral absorption, increasing endogenous losses and reducing broiler performance. The objective of this study was to investigate the anti-nutritional effects of phytate by including high levels of phytase in diets not severely limited in available P. A total of 768 male Arbor Acres broilers were distributed in six treatments of eight replicate pens of 16 birds each consisting of a positive control diet (PC, positive control with 500 FTU/kg phytase, negative control (NC diet with lower available P and calcium (Ca levels and the same NC diet with 500, 1,000 or 1,500 FTU/kg phytase. Body weight gain (BWG, feed intake (FI, feed conversion ratio (FCR and mortality were determined at 21 and 35 d of age while foot ash was determined in four birds per pen at 21 d of age. FI, FCR and foot ash where not affected by the lower mineral diets at 21 d of age nor by the enzyme inclusion but broilers fed lower Ca and available P diets had lower BWG. At 35 d of age no difference was observed between broilers fed the positive or NC diets but broilers fed 500, 1,000 and 1,500 FTU/kg on top of the NC diet had better FCR than broilers fed the positive control diet. When compared to birds fed a diet adequate in P, birds fed the same diet included with 500, 1,000 and 1,500 FTU/kg of phytase in marginally deficient available P and Ca diets had an improvement of performance. These results support the concept that hydrolysing phytate and reducing the anti-nutritional effects of phytate improves bird performance on marginally deficient diets that were not covering the P requirement of birds.

What is the central question of this study? Does attenuated skin blood flow diminish sweating and reduce the critical environmental limit for heat balance, which indicates maximal heat loss potential, during severe heat stress? What is the main finding and its importance? Isosmotic hypovolaemia attenuated skin blood flow by ∼20% but did not result in different sweating rates, mean skin temperatures or critical environmental limits for heat balance compared with control and volume-infusion treatments, suggesting that the lower levels of skin blood flow commonly observed in aged and diseased populations may not diminish maximal whole-body heat dissipation. Attenuated skin blood flow (SkBF) is often assumed to impair core temperature (T c ) regulation. Profound pharmacologically induced reductions in SkBF (∼85%) lead to impaired sweating, but whether the smaller attenuations in SkBF (∼20%) more often associated with ageing and certain diseases lead to decrements in sweating and maximal heat loss potential is unknown. Seven healthy men (28 ± 4 years old) completed a 30 min equilibration period at 41°C and a vapour pressure (P a ) of 2.57 kPa followed by incremental steps in P a of 0.17 kPa every 6 min to 5.95 kPa. Differences in heat loss potential were assessed by identifying the critical vapour pressure (P crit ) at which an upward inflection in T c occurred. The following three separate treatments elicited changes in plasma volume to achieve three distinct levels of SkBF: control (CON); diuretic-induced isosmotic dehydration to lower SkBF (DEH); and continuous saline infusion to maintain SkBF (SAL). The T c , mean skin temperature (T sk ), heart rate, mean laser-Doppler flux (forearm and thigh; LDF mean ), mean local sweat rate (forearm and thigh; LSR mean ) and metabolic rate were measured. In DEH, a 14.2 ± 5.7% lower plasma volume resulted in a ∼20% lower LDF mean in perfusion units (PU) (DEH, 139 ± 23 PU; CON, 176 ± 22 PU; and SAL
As in adult anesthesia, morbidity and mortality could be significantly reduced in pediatric anesthesia in recent decades. This fact cannot conceal the fact that the incidence of anesthetic complications in children is still much more common than in adults and sometimes with a severe outcome. Newborns and infants in particular but also children with emergency interventions and severe comorbidities are at increased risk of potential complications. Typical complications in pediatric anesthesia are respiratory problems, medication errors, difficulties with the intravenous puncture and pulmonal aspiration. In the postoperative setting, nausea and vomiting, pain, and emergence delirium can be mentioned as typical complications. In addition to the systematic prevention of complications in pediatric anesthesia, it is important to quickly recognize disturbances of homeostasis and treat them promptly and appropriately. In addition to the expertise of the performing anesthesia team, the institutional structure in particular can improve quality and safety in pediatric anesthesia.

This paper reports the CT findings of major postpartum complications and determine what role CT plays in their evaluation. The CT scans of nine patients with major postpartum complications were retrospectively reviewed. Patients had been referred to CT for evaluation of postpartum fever, abdominal pain, and elevated results of liver function tests. Complications identified at CT included hepatic infarctions (n = 2), endometritis (n = 2), postoperative wound abscess (n = 1), massive abdominal hemorrhage (n = 1), septic thrombophlebitis (n = 1), and renal vein thrombosis (n = 1). CT findings of hepatic infarction included wedge-shaped areas of decreased enhancement conforming to a vascular distribution

A reduced cardiac output (CO) response during exercise is a major limiting factor in heart failure (HF). Oxygen consumption (VO 2 ) is directly proportional to CO. Peripheral mechanisms via arteriovenous oxygen difference (Δ(a-v)O 2 ) play a pivotal role in chronic HF. We hypothesized a weak correlation between peak VO 2 and peak CO with a greater Δ(a-v)O 2 variability in most severe HF. We analyzed 278 HF patients (NYHA II-III) who performed maximal cardiopulmonary exercise test with non-invasive CO measurement by inert gas rebreathing. Median peakVO 2 , CO and Δ(a-v)O 2 were 0.96 (0.78-1.28) L/min, 6.3 (5.1-8.0) L/min and 16.0 (14.2-18.0) mL/100mL respectively, with a linear relationship between VO 2 and CO: CO=5.3×VO 2 +1.13 (r 2 =0.705, pexercise limitation. Group 1 (101 patients) peakVO 2 <50% pred: peakVO 2 0.80 (0.67-0.94) L/min, peakCO 5.6 (4.7-6.5) L/min, peakΔ(a-v)O 2 14.8 (12.9-17.1) mL/100mL. Group 2 (89 patients) peakVO 2 ≥50-<65% pred: peakVO 2 1.02 (0.84-1.29) L/min, peakCO 6.4 (5.1-8.0) L/min, peakΔ(a-v)O 2 16.7 (15.0-18.5) mL/100mL. Group 3 (88 patients) peakVO 2 ≥65% pred: peakVO 2 1.28 (0.93-1.66) L/min, peakCO 8.0 (6.2-9.7) L/min, peakΔ(a-v)O 2 16.8 (14.6-18.3) mL/100mL. A peakVO 2 and peakCO linear relationship was observed in Group 1 (r 2 =0.381, p<0.001), Group 2 (r 2 =0.756, p<0.001) and Group 3 (r 2 =0.744, p<0.001). With worsening HF we observed a progressive reduction of peak CO and peak VO 2 . However in most compromised patients also peripheral mechanisms play a role as indicated by reduced Δ(a-v)O 2 .

Objective To project the proportion of population 65+ years with severe long-term activity limitations from 2017 to 2047. Design Large population study. Setting Population living in private households of the European Union (EU) and neighbouring countries. Participants Participants from the EU Statistics on Income and Living Conditions aged 55 years and older and living in one of 26 EU and neighbouring countries, who answered the health section of the questionnaire. Outcome measures Prevalence of severe long-term activity limitations of particular subpopulations (ie, 55+, 65+, 75+ and 85+ years) by sex and country. Results We find a huge variation in the prevalence of self-reported severe long-term limitations across Europe for both sexes. However, in 2017, about 20% of the female population aged 65 years and above and about 16% of their male counterparts are expected to report severe long-term activity limitations after accounting for differences in reporting. Accounting for cultural differences in reporting, we expect that European countries will have about 21% (decile 1: 19.5%; decile 9: 22.9%) of female and about 16.8% (decile 1: 15.4%; decile 9: 18.1%) of male 65+ years population with severe long-term activity limitations by 2047. Conclusions Overall, despite the expected increase of life expectancy in European countries, our results suggest almost constant shares of older adults with severe long-term activity limitations within the next 30 years.

Full Text Available Mechanical ventilation of the lungs, as an important therapeutic measure, cannot be avoided in critically ill patients. However, when machines take over some of vital functions there is always a risk of complications and accidents. Complications associated with mechanical ventilation can be divided into: 1 airway-associated complications; 2 complications in the response of patients to mechanical ventilation; and 3 complications related to the patient’s response to the device for mechanical ventilation. Complications of artificial airway may be related to intubation and extubation or the endotracheal tube. Complications of mechanical ventilation, which arise because of the patient’s response to mechanical ventilation, may primarily cause significant side effects to the lungs. During the last two decades it was concluded that mechanical ventilation can worsen or cause acute lung injury. Mechanical ventilation may increase the alveolar/capillary permeability by overdistension of the lungs (volutrauma, it can exacerbate lung damage due to the recruitment/derecruitment of collapsed alveoli (atelectrauma and may cause subtle damages due to the activation of inflammatory processes (biotrauma. Complications caused by mechanical ventilation, beside those involving the lungs, can also have significant effects on other organs and organic systems, and can be a significant factor contributing to the increase of morbidity and mortality in critically ill of mechanically ventilated patients. Complications are fortunately rare and do not occur in every patient, but due to their seriousness and severity they require extensive knowledge, experience and responsibility by health-care workers.

Oral piercings have a long history as part of religious, cultural, or sexual symbolism in many traditional tribes; currently, these ornaments have wide acceptance among young people. Several oral and systemic complications may be associated with this practice; however, limited data related to these complications can be obtained in the literature. This study includes 42 cases of oral piercings in 39 young adults, who were using or had used oral piercings, and the complications associated with their use. Immediate complications occurred in 29 cases, including excessive bleeding (69%) and pain (52.3%) as the most representative. Two cases of syncope were found. Late complications related to the piercing insertion site were observed in 97.6% of cases, with pain and swelling being present in 92.9% and 61.9% of cases, respectively. Dental pain and lacerations on the tongue represented the most prevalent complications associated with the surrounding tissues, accounting for 33.3% and 31% of cases. The use of oral piercings is related to a series of mainly local complications, and individuals who decide to use piercings should be aware of such complications. Individuals wishing to get a part of their body pierced should do so with qualified professionals and should regularly visit the dentist so that a regular control is achieved, thus ensuring the early detection of the adverse effects associated with this practice.

We describe a rare case of fatal mumps encephalomyelitis occurring in 19-year old male following matched unrelated donor peripheral blood haematopoietic stem cell transplantation (HSCT). The indication for HSCT was for an undefined form of severe combined immunodeficiency (SCID). Molecular typing of the mumps viral RNA isolated from neural tissue indicated that the infection was acquired at the time of a mumps outbreak in England and Wales that occurred between 2004 and 2006. This case highlights the importance of considering mumps in the differential diagnosis of central nervous system infection in highly immunosuppressed patients. Copyright © 2013 Elsevier B.V.

Full Text Available A randomized complete block design with four replications and a split plot arrangement was conducted in 2010, in order to study the effect of limited irrigation on yield and yield component of sweet corn. Water levels were (100%, 80%, and 60% replacement of plant water requirement which served as main plots. Subplot was a factorial arrangement of three different sweet corn varieties (Merit, Obsession and KSC403 with two planting methods (raised bed and furrow planting. The evaluated traits were ear length, ear diameter, kernels number per row, seed rows per ear, kernel depth, seed thousands weight, kernel yield, shoot biomass, harvest index and Anthesis- silking interval. Results show that limited irrigation significantly decreased all measured characteristics but harvest index. Effect of varieties was significant on evaluated traits too. Kernel weight and seed depth were significantly affected by interaction between variety and planting method. The highest yield was found for 100% replacement of water requirement irrigation level whit 15.2 tones per hectare kernel weight and the lowest belongs to 60% replacement of water requirement by 8.6 tones per hectare kernel weight. Merit and KSC 403 produces the highest (15.9 ton/ha and lowest (8.8 ton/ha seed yield, respectively. Harvest index of different varieties were not affected by irrigation regime. Results show that, in whole, limited irrigation, decreased seed yield in all varieties by affecting diverse yield component.

Hemolytic disease of the fetus and newborn caused by anti-G antibodies is rare, and in most previously reported cases, leads to a mild anemia. The RhG antigen is usually found in association with both RhD and RhC. We report a case of a twin pregnancy affected by both anti-G and anti-C alloantibodies leading to severe hemolytic disease of the fetus and newborn requiring multiple intrauterine transfusions and prolonged postnatal therapy. A patient with a prolonged history of previously affected pregnancies due to anti-D and anti-C was subsequently found to be affected with anti-G instead. She required aggressive therapy during her pregnancy, initially with intravenous immune globulin and plasmapheresis until umbilical blood sampling and intrauterine transfusions were feasible. Although hemolytic disease of the fetus and newborn due to anti-G antibodies is rare and usually mild, these pregnancies should be followed up closely and in utero therapy should be offered if necessary.
Full Text Available The feasibility of using water glass and aluminum sulfate to treat high liquid limit soil subgrade diseases is studied through laboratory experiments, and the following results were observed. After improving the high liquid limit clay with water glass and aluminum sulfate, the liquid limit decreases, the plastic limit increases, and the plasticity index decreases. Compared with untreated soil, the clay content of the improved soil decreases, while the silt and coarse contents increase. The absolute and relative expansion rates of the improved soil are both lower than those of the untreated soil. With the same number of dry and wet cycles, the decreased degrees of cohesion and internal friction angle of the improved soil are, respectively, one-half and one-third of those of the untreated soil. After three dry and wet cycles, the California bearing ratio (CBR of the untreated soil does not meet the requirements of specifications. However, after being cured for seven days and being subjected to three dry and wet cycles, the CBR of the improved soil, with 4% water glass solution and 0.4% aluminum sulfate, meets the requirements of specifications.

We analysed the distribution of the body mass index standard deviation scores (BMI-SDS) in children and adolescents seeking treatment for severe obesity, according to the International Obesity Task Force (IOTF), World Health Organization (WHO) and the national Norwegian Bergen Growth Study (BGS) BMI reference charts and the percentage above the International Obesity Task Force 25 cut-off (IOTF-25). This was a cross-sectional study of 396 children aged four to 17 years, who attended a tertiary care obesity centre in Norway from 2009 to 2015. Their BMI was converted to SDS using the three growth references and expressed as the percentage above IOTF-25. The percentage of body fat was assessed by bioelectrical impedance analysis. Regardless of which BMI reference chart was used, the BMI-SDS was significantly different between the age groups, with a wider range of higher values up to 10 years of age and a more narrow range of lower values thereafter. The distributions of the percentage above IOTF-25 and percentage of body fat were more consistent across age groups. Our findings suggest that it may be more appropriate to use the percentage above a particular BMI cut-off, such as the percentage above IOTF-25, than the IOTF, WHO and BGS BMI-SDS in paediatric patients with severe obesity. ©2017 Foundation Acta Paediatrica.

Full Text Available In the United States, circumcision is a commonly performed procedure. It is a relatively safe procedure with a low overall complication rate. Most complications are minor and can be managed easily. Though uncommon, complications of circumcision do represent a significant percentage of cases seen by pediatric urologists. Often they require surgical correction that results in a significant cost to the health care system. Severe complications are quite rare, but death has been reported as a result in some cases. A thorough and complete preoperative evaluation, focusing on bleeding history and birth history, is imperative. Proper selection of patients based on age and anatomic considerations as well as proper sterile surgical technique are critical to prevent future circumcision-related adverse events.

During the treatment phase of active pulmonary tuberculosis (PTB), respiratory function impairment is usually restrictive. This may become obstructive, as a PTB-associated airflow obstruction (AFO) or as a later manifestation of underlying COPD. The aim of the study was to examine the potential causes and risks for AFO development in PTB by exploring the aspects of spirometry limitations and clinical implications for the underlying COPD detection, taking into account various confounding factors. Prospective, nest case-control study on 40 new cases of PTB with initial restrictive respiratory function impairment, diagnosed and treated according to the directly observed treatment short course (DOTS) strategy. From all observed patients, 37.5% of them developed AFO upon the completion of PTB treatment, with significantly increased average of forced vital capacity (%) (Ppulmonary tuberculosis lesions (OR 1.01-1.05 for 95% CI; P=0.02) and sputum conversion rate on culture (OR 1.02-1.68 for 95% CI; P=0.04) as the most significant predictors for the risk of AFO development. AFO upon PTB treatment is a common manifestation of underlying COPD, which mostly occurs later, during the reparative processes in active PTB, even in the absence of major risk factors, such as cigarette smoking and biomass fuel dust exposure. Initial spirometry testing in patients with active PTB is not a sufficient and accurate approach in the detection of underlying COPD, which may lead to their further potential health deterioration.

Severe hypoglycemia is a feared complication of type 1 diabetes; yet, few trials have targeted prevention using optimized self-management (educational, therapeutic, and technological support). We aimed to investigate whether improved awareness and reduced severe hypoglycemia, achieved during an intensive randomized clinical trial (RCT), were sustained after return to routine care. Ninety-six adults with type 1 diabetes (29 ± 12 years' duration) and impaired awareness of hypoglycemia at five U.K. tertiary referral diabetes centers were recruited into a 24-week 2 × 2 factorial RCT (HypoCOMPaSS). Participants were randomized to pump (continuous subcutaneous insulin infusion [CSII]) or multiple daily injections (MDIs) and real-time continuous glucose monitoring (RT-CGM) or self-monitoring of blood glucose (SMBG), with equal education/attention to all groups. At 24 weeks, participants returned to routine care with follow-up until 24 months, including free choice of MDI/CSII; RT-CGM vs. SMBG comparison continued to 24 months. Primary outcome was mean difference (baseline to 24 months [between groups]) in hypoglycemia awareness. Improvement in hypoglycemia awareness was sustained (Gold score at baseline 5.1 ± 1.1 vs. 24 months 3.7 ± 1.9; P diabetes complicated by impaired awareness of hypoglycemia. © 2018 by the American Diabetes Association.

Some patients with chronic obstructive pulmonary disease (COPD) fail to achieve health benefits with pulmonary rehabilitation (PR). Exercise intensity and load represent stimulus for adaptation but it is unclear whether inappropriate exercise intensity and/or load are affected by severity of COPD, which may affect health benefits. The purpose was to determine whether COPD severity and/or the severity of pulmonary limitation to exercise (PLE) impacted exercising intensity or load and whether resultant intensity/load affected health outcomes derived from PR. Patients with COPD (n = 58, age = 67 ± 7 y, forced expiratory volume in the first second of expiration [FEV1] % predicted = 52 ± 21%) were recruited upon referral to PR. Primary health outcomes evaluated were 6-min walk distance and St George's Respiratory Questionnaire. Patients were stratified for disease severity using Global Initiative for Obstructive Lung Disease (GOLD) staging and PLE severity by change in inspiratory capacity during exercise. Exercise intensity and load were calculated from daily exercise records. Participants achieved comparable training duration and load regardless of GOLD severity. Patients with more severe PLE achieved greater training duration (more severe: 546 ± 143 min., less severe: 451 ± 109 min., P = .036), and relative training load (more severe: 2200.8 ± 595.3 kcal, less severe: 1648.3 ± 597.8 kcal, P = .007). Greater overall training load was associated with greater improvements in 6-min walk distance (r = 0.24, P = .035). No significant relationships were observed between PLE, GOLD severity, training parameters, and St George's Respiratory Questionnaire response. Improvements in exercise tolerance can be explained by achieving greater training loads, demonstrating the importance of appropriate training load to maximize health outcomes in PR.

The received account of whistleblowing, developed over the last quarter century, is identified with the work of Norman Bowie and Richard DeGeorge. Michael Davis has detailed three anomalies for the received view: the paradoxes of burden, missing harm and failure. In addition, he has proposed an alternative account of whistleblowing, viz., the Complicity Theory. This paper examines the Complicity Theory. The supposed anomalies rest on misunderstandings of the received view or misreadings of model cases of whistleblowing, for example, the Challenger disaster and the Ford Pinto. Nevertheless, the Complicity Theory is important for as in science the contrast with alternative competing accounts often helps us better understand the received view. Several aspects of the received view are reviewed and strengthened through comparison with Complicity Theory, including why whistleblowing needs moral justification. Complicity Theory is also critiqued. The fundamental failure of Complicity Theory is its failure to explain why government and the public encourage and protect whistleblowers despite the possibility of considerable harm to the relevant company in reputation, lost jobs, and lost shareholder value.

Degenerative forms of mitral valve diseases (MVDs) are very complex pathologies. Thus, it is difficult to make generalizations about the disease pathways or genetic risk factors contributing to these diseases. However, a key role of metalloproteinases (MMPs) in their pathophysiology is emerging. Thus, we performed for the first time a perspective study to assess eventual associations of some functional single nucleotide polymorphisms (SNPs) in MMP-2 and MMP-9 genes with the MVD risk, symptom severity, and short- and long-term (4.8 years) complications. For this purpose, 90 patients and two control groups were genotyped for rs3918242, rs243865, and rs2285053 MMP-2 and MMP-9 gene SNPs, and systemic levels of pro-atrial natriuretic peptide (pro-ANP) and two enzymes were quantified and correlated to genotypes of MMP-2 and MMP-9 SNPs studied. In addition, associations between these SNPs and symptom severity and short- and long-term (4.8 years) complications were evaluated. Interestingly, rs3918242 MMP-9 and rs2285053 MMP-2 SNPs were significantly represented in cases than two control groups and were associated with a higher MVD risk, as demonstrated using dominant/recessive models. Cases stratified for NYHA symptoms and particularly those NYHA III+IV with rs3918242 CT+TT MMP-9 and rs2285053CT+TT genotypes also showed higher severity related to significant higher systemic levels of MMP enzymes and pro-ANP at enrolment and 4.8 follow-up times. In addition, cases with these genotypes and particularly those NYHA III+IV had a very significant percentage of complications, particularly at the 4.8 follow-up. Surprisingly, 20% of patient controls developed MVD at 4.8-year follow-up and were carriers of these genotypes. Thus, the associations observed seem to suggest that the two SNPs might represent useful biomarkers and targets for preventing and monitoring MVDs and developing personalized treatments, consenting a more appropriate management and outcome.

Thyroid hormones exert multiple effects on the neuromuscular system and the brain, with the most important being their role in stimulating the development and differentiation of the neuromuscular system and brain in foetal and neonatal life. In the presence of hyperthyroidism, muscular and neurological symptoms may be the presenting clinical features of the disease. The frequency and severity of neuromuscular complications vary considerably and are probably related to the degree of hyperthyroidism, although in some patients the neuromuscular dysfunction is caused by associated disorders rather than by hyperthyroidism per se. This update focuses on the most common neurological and muscular disorders that occur in patients with thyrotoxicosis. It is beyond the scope of this paper to discuss thyroid eye disease and cardiac complications, in themselves separate complications of specific myocytes.

Over the past 20 to 30 years, arthroscopic shoulder techniques have become increasingly popular. Although these techniques have several advantages over open surgery, surgical complications are no less prevalent or devastating than those associated with open techniques. Some of the complications associated with arthroscopic shoulder surgery include recurrent instability, soft-tissue injury, and neurapraxia. These complications can be minimized with thoughtful consideration of the surgical indications, careful patient selection and positioning, and a thorough knowledge of the shoulder anatomy. Deep infection following arthroscopic shoulder surgery is rare; however, the shoulder is particularly susceptible to Propionibacterium acnes infection, which is mildly virulent and has a benign presentation. The surgeon must maintain a high index of suspicion for this infection. Thromboemoblic complications associated with arthroscopic shoulder techniques are also rare, and studies have shown that pharmacologic prophylaxis has minimal efficacy in preventing these complications. Because high-quality studies on the subject are lacking, minimal evidence is available to suggest strategies for prevention. Copyright 2014 by the American Academy of Orthopaedic Surgeons.
Full Text Available Following the death of a loved one, a small group of grievers develop an abnormal grieving style, termed complicated or prolonged grief. In the effort to establish complicated grief as a disorder in DSM and ICD, several attempts have been made over the past two decades to establish symptom criteria for this form of grieving. Complicated grief is different from depression and PTSD yet often comorbid with other psychological disorders. Meta-analyses of grief interventions show small to medium effect sizes, with only few studies yielding large effect sizes. In this article, an integrative cognitive behavioral treatment manual for complicated grief disorder (CG-CBT of 25 individual sessions is described. Three treatment phases, each entailing several treatment strategies, allow patients to stabilize, explore, and confront the most painful aspects of the loss, and finally to integrate and transform their grief. Core aspects are cognitive restructuring and confrontation. Special attention is given to practical exercises. This article includes the case report of a woman whose daughter committed suicide.

Inverse limits provide a powerful tool for constructing complicated spaces from simple ones. They also turn the study of a dynamical system consisting of a space and a self-map into a study of a (likely more complicated) space and a self-homeomorphism. In four chapters along with an appendix containing background material the authors develop the theory of inverse limits. The book begins with an introduction through inverse limits on [0,1] before moving to a general treatment of the subject. Special topics in continuum theory complete the book. Although it is not a book on dynamics, the influen

Parenting stress in mothers of children with autism spectrum disorder (ASD) is high and impacts perceptions about parenting. This study examined the relationship between parenting stress and observer-perceived limit-setting ability. Participants' perceptions of other parents' limit-setting ability were assessed by showing participants video clips of parenting behaviours. Mothers of 93 children with autism spectrum disorder completed an online survey regarding the severity of their own child's autism spectrum disorder (Social Communication Questionnaire), their child's behaviour problems (Strengths and Difficulties Questionnaire) and their own levels of parenting stress (Questionnaire on Resources and Stress). They were shown five videos of other parents interacting with children with autism spectrum disorder and were asked to rate the limit-setting abilities observed in each video using the Parent-Child Relationship Inventory. Higher parenting stress negatively related to judgements about others' limit-setting skills. This mirrors the literature regarding the relationship between self-reported parenting stress and rating child behaviour more negatively. It suggests that stress negatively impacts a wide range of judgements and implies that caution may be required when interpreting the results of studies in which parenting skills are assessed by self-report.

Pregnancy causes significant metabolic and hemodynamic changes in a woman’s physiology to allow for fetal growth. The inability to adapt to these changes might result in the development of hypertensive disorders of pregnancy (hypertension, preeclampsia or eclampsia), gestational diabetes and preterm birth. Contrary to previous beliefs these complications are not limited to the pregnancy period and may leave permanent vascular and metabolic damage. There is in addition, a direct association between these disorders and increased risk of future cardiovascular disease (CVD, including hypertension, ischemic heart disease, heart failure and stroke) and diabetes mellitus. Despite abundant evidence of this association, women who present with these complications of pregnancy do not receive adequate postpartum follow up and counseling regarding their increased risk of future CVD. The postpartum period in these women represents a unique opportunity to intervene with lifestyle modifications designed to reduce the development of premature cardiovascular complications. In some cases it allows early diagnosis and treatment of chronic hypertension or diabetes mellitus. The awareness of this relationship is growing in the medical community, especially among obstetricians and primary care physicians, who play a pivotal role in detecting these complications and assuring appropriate follow up.

Splenectomy is attended by medical complications, principally infectious and thromboembolic; the frequency of complications varies with the conditions that led to splenectomy (hematologic splenectomy, trauma, presence of portal hypertension). Most infectious complications are caused by encapsulated bacteria (Meningococcus, Pneumococcus, Hemophilus). These occur mainly in children and somewhat less commonly in adults within the first two years following splenectomy. Post-splenectomy infections are potentially severe with overwhelming post-splenectomy infection (OPSI) and this justifies preventive measures (prophylactic antibiotics, appropriate immunizations, patient education) and demands prompt antibiotic management with third-generation cephalosporins for any post-splenectomy fever. Thromboembolic complications can involve both the caval system (deep-vein thrombophlebitis, pulmonary embolism) and the portal system. Portal vein thrombosis occurs more commonly in patients with myeloproliferative disease and cirrhosis. No thromboembolic prophylaxis is recommended apart from perioperative low molecular weight heparin. However, some authors choose to prescribe a short course of anti-platelet medication if the post-splenectomy patient develops significant thrombocytosis. Thrombosis of the portal or caval venous system requires prolonged warfarin anticoagulation for 3 to 6 months. Finally, some studies have suggested an increase in the long-term incidence of cancer in splenectomized patients. Copyright © 2016 Elsevier Masson SAS. All rights reserved.
Approximately 24,000 patients are diagnosed each year with malignant tumors of the head and neck. Many of these patients will be treated with radiotherapy, surgery, or chemotherapy, either singly or in combination. Certain predictable sequelae of radiotherapy exist that may be considered consequences of treatment rather than complications; these may be unavoidable consequences of curative radiotherapy to the head and neck. There are, however, additional problems that occur as a result of radiotherapy that are preventable in both incidence and severity, and are therefore avoidable complications. Cell kinetic factors, radiosensitivity of normal tissues, radiotherapeutic doses necessary for tumor control, and the complex anatomy of the maxillofacial region often predispose patients serious treatment morbidity. The potential for pain, infection, and long-term functional disability with decreased quality of life dictate conscientious management before, during, and after radiotherapy. This chapter discusses common problems that can arise, as well as current methods utilized both to improve patient tolerance to treatment and to decrease the risk of preventable and potentially dose-limiting morbidity

Older community-living disabled people often have unmet activity needs and participation restrictions potentially reducing their quality of life (QoL). We examined the effects of an individualized out-of-home activity intervention delivered by volunteers on QoL among community-living older people, who have difficulty accessing the outdoors independently. Volunteering, Access to Outdoor Activities and Wellbeing in Older People (VOW; ISRCTN56847832) was a two-arm randomized single-blinded, controlled effectiveness trial (RCT) in Jyväskylä, Finland. The inclusion criteria were: age 65 or over, severe mobility limitation, able to communicate, and agree to participate in a RCT. Each intervention group member was assigned a trained volunteer with whom out-of-home activities were done once a week for 3 months (e.g., running errands or recreational activities). The primary outcome was the environmental subscore of QoL assessed with WHOQOL-BREF. Secondary outcomes were the overall QoL, physical capacity, psychological well-being, and social relationships assessed with WHOQOL_BREF and lower-extremity performance assessed with Short Physical Performance Battery (SPPB). 121 people aged 67-92 years (mean age 81.9 years, SD 5.9, 90 % women) were randomized. No treatment effect on the environmental QoL subscore was observed, but for physical capacity subscore a significant treatment effect was observed (General Linear Model, Group by Time p = 0.001). No effects were observed for the other QoL subscores or for SPPB score. This study suggests that individualized out-of-home activity intervention delivered by volunteers may influence the QoL of old severely mobility-limited community-living people in a positive way. Further studies are needed to better understand how to improve QoL of older disabled community-living people and potentially buffer them against more severe care needs and institutionalization.

An imbalance between anti- and angiogenic factors during early placentation is key for the development of preeclampsia. Nevertheless, the majority of studies addressing this issue relate to maternal blood and not the fetal circulation. To measure placental growth factor (PlGF), free beta human chorionic gonadotropin (β-hCG), and pregnancy-associated plasma protein-A (PAPP-A) levels in the fetal circulation of near-term pregnancies complicated with severe preeclampsia (n = 20), and their controls matched for parity, and maternal and gestational age. Upon delivery, a blood sample was withdrawn from the umbilical artery and vein of each case and its control in order to measure the proposed analytes using direct fluoroimmunoassay. Preeclampsia cases showed significantly lower median PlGF levels in fetal circulation as compared to controls (25.2 versus 36.9 and 23.6 versus 33.9 pg/mL, artery and vein, respectively, p < 0.05). Contrarily, cases displayed higher concentrations of PAPP-A (1024.0 versus 720.9 [median] and 1027.0 ± 298.4 versus 690.3 ± 401.9 mIU/L, artery and vein, respectively, p < 0.05), and free β-hCG (mean: 33.9 ± 4.3 versus 17.2 ± 4.0 and 30.1 ± 5.2 versus 13.7 ± 3.3 ng/mL, artery, and vein respectively, p < 0.05). Lower PlGF and higher PAPP-A and free β-hCG levels were found in the fetal circulation of near-term severe preeclamptic pregnancies. There is a need for more research in this regard.

Full Text Available Nervous system lesions associated with chronic alcohol intoxication are common in clinical practice. They lead to aggravated alcoholic disease, its more frequent recurrences, and intensified pathological craving for alcohol. Neurological pathology in turn occurs with frequent exacerbations. The interaction of diseases, age, and medical pathomorphism modifies the clinical presentation and course of the major pathology, as well as comorbidity, the nature and severity of complications, worsens quality of life in a patient, and makes the diagnostic and treatment process difficult. The paper discusses the classification, clinical variants, biochemical and molecular biological aspects of various complications of alcoholic disease. It considers its most common form, in particular alcoholic polyneuropathy, as well as its rarer variants, such as hemorrhagic encephalopathy with a subacute course (Gayet–Wernicke encephalopathy.

Obesity usually is associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause (eg, nonalcoholic fatty liver disease) or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease, erosive esophagitis, Barrett’s esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including nonalcoholic fatty liver disease, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer. Gastroenterologists are uniquely poised to participate in the multidisciplinary management of obesity as physicians caring for people with obesity-related diseases, in addition to their expertise in nutrition and endoscopic interventions.

Fractional photothermolysis represents a new modality of laser skin resurfacing that was developed to provide a successful clinical response while minimizing postoperative recovery and limiting treatment complications. To review all of the reported complications that develop as a result of fractional ablative and nonablative laser skin resurfacing. A literature review was based on a MEDLINE search (1998-2009) for English-language articles related to laser treatment complications and fractional skin resurfacing. Articles presenting the highest level of evidence and the most recent reports were preferentially selected. Complications with fractional laser skin resurfacing represent a full spectrum of severity and can be longlasting. In general, a greater likelihood of developing post-treatment complications is seen in sensitive cutaneous areas and in patients with intrinsically darker skin phototypes or predisposing medical risk factors. Although the overall rate of complications associated with fractional laser skin resurfacing is much lower than with traditional ablative techniques, recent reports suggest that serious complications can develop. An appreciation of all of the complications associated with fractional laser skin resurfacing is important, especially given that many of them can be potentially prevented. The authors have indicated no significant interest with commercial supporters.

Pulmonary tuberculosis (TB) is a risk factor for chronic obstructive pulmonary disease (COPD); however, few clinical studies have investigated treatment effectiveness in COPD patients with destroyed lung by TB. The Indacaterol effectiveness in COPD patients with Tuberculosis history (INFINITY) study assessed the efficacy and safety of once-daily inhaled indacaterol 150 µg for the treatment of Korean COPD patients with destroyed lung by TB and moderate-to-severe airflow limitation. This was a multicenter, double-blind, parallel-group study, in which eligible patients were randomized (1:1) to receive either once-daily indacaterol 150 µg or placebo for 8 weeks. The primary efficacy endpoint was change from baseline in trough forced expiratory volume in 1 s at Week 8; the secondary endpoints included changes in transition dyspnea index score and St George's Respiratory Questionnaire for COPD score at Week 8. Safety was evaluated over 8 weeks. Of the 136 patients randomized, 119 (87.5%) completed the study treatment. At Week 8, indacaterol significantly improved trough forced expiratory volume in 1 s versus placebo (treatment difference [TD] 140 mL, P <0.001). Statistically significant improvement in transition dyspnea index score (TD =0.78, P <0.05) and numerical improvement in St George's Respiratory Questionnaire for COPD score (TD =-2.36, P =0.3563) were observed with indacaterol versus placebo at Week 8. Incidence of adverse events was comparable between the treatment groups. Indacaterol provided significantly superior bronchodilation, significant improvement in breathlessness and improved health status with comparable safety versus placebo in Korean COPD patients with destroyed lung by TB and moderate-to-severe airflow limitation.
Full Text Available INTRODUCTION Despite high graft and recipient survival figures worldwide today, a variety of technical complications can threaten the transplant in the postoperative period. Vascular complications are commonly related to technical problems in establishing vascular continuity or to damage that occurs during donor nephrectomy or preservation . AIM The aim of the presenting study is to evaluate counts and rates of vascular complications after renal transplantation and to compare the outcome by donor type. MATERIAL AND METHODS A total of 463 kidneys (319 from living related donor LD and 144 from cadaveric donor - CD were transplanted during the period between June 1975 and December 1998 at the Urology & Nephrology Institute of Clinical Centre of Serbia in Belgrade. Average recipients' age was 33.7 years (15-54 in LD group and 39.8 (19-62 in CD group. Retrospectively, we analyzed medical records of all recipients. Statistical analysis is estimated using Hi-squared test and Fischer's test of exact probability. RESULTS Major vascular complications including vascular anastomosis thrombosis, internal iliac artery stenosis, internal iliac artery rupture obliterant vasculitis and external iliac vein rupture were analyzed. In 25 recipients (5.4% some of major vascular complications were detected. Among these cases, 22 of them were from CD group vs. three from LD group. Relative rate of these complications was higher in CD group vs. LD group (p<0.0001. Among these complications dominant one was vascular anastomosis thrombosis which occurred in 18 recipients (17 from CD vs. one from LD. Of these recipients 16 from CD lost the graft, while the rest of two (one from each group had lethal outcome. DISCUSSION Thrombosis of renal allograft vascular anastomosis site is the most severe complication following renal transplantation. In the literature, renal allograft thrombosis is reported with different incidence rates, from 0.5-4% [14, 15, 16]. Data from the

Full Text Available OBJETIVO: Analisar os resultados da avaliação da vitalidade fetal em gestações complicadas por plaquetopenia materna moderada ou grave. MÉTODOS: No período de abril de 2001 a julho de 2011, foram analisados, retrospectivamente, os dados de prontuários de 96 gestantes com diagnóstico de plaquetopenia na gestação. Foram analisados os seguintes exames de avaliação da vitalidade fetal realizados no período anteparto: cardiotocografia, perfil biofísico fetal, índice de líquido amniótico e doplervelocimetria das artérias umbilicais. RESULTADOS: Foram analisadas 96 gestações com os seguintes diagnósticos: plaquetopenia gestacional (n=37, 38,5%, hiperesplenismo (n=32, 33,3%, púrpura trombocitopenica imune (PTI, n=14, 14,6%, plaquetopenia imune secundária (n=6, 6,3%, aplasia medular (n=3, 3,1% e outros (n=4, 4,1%. A cardiotocografia apresentou resultado normal em 94% dos casos, o perfil biofísico fetal com índice 8 ou 10 em 96,9% e o índice de líquido amniótico >5,0 cm em 89,6%. A doplervelocimetria da artéria umbilical apresentou resultado normal em 96,9%. Na análise dos principais grupos de plaquetopenia, constatou-se que o diagnóstico de oligohidrâmnio foi significativamente mais frequente no grupo com PTI (28,6% quando comparado aos demais (gestacional: 5,4% e hiperesplenismo: 9,4%, p=0,04. CONCLUSÕES: O presente estudo permitiu concluir que, nas gestações complicadas pela plaquetopenia materna moderada ou grave, apesar do bem-estar fetal manter-se preservado na grande maioria dos casos, em gestantes com PTI é importante o seguimento da vitalidade fetal com ênfase na avaliação do volume de líquido amniótico, devido à sua associação com a oligohidramnia.PURPOSE: To analyze the results of assessment of fetal well-being in pregnancies complicated by moderate or severe maternal thrombocytopenia.

Full Text Available There is a paucity of strong evidence associated with adverse pregnancy outcomes and thrombophilia in pregnancy. These problems include both early (recurrent miscarriage and late placental vascular-mediated problems (fetal loss, pre-eclampsia, placental abruption and intra-uterine growth restriction. Due to poor quality case-control and cohort study designs, there is often an increase in the relative risk of these complications associated with thrombophilia, particularly recurrent early pregnancy loss, late fetal loss and pre-eclampsia, but the absolute risk remains very small. It appears that low-molecular weight heparin has other benefits on the placental vascular system besides its anticoagulant properties. Its use is in the context of antiphospholipid syndrome and recurrent pregnancy loss and also in women with implantation failure to improve live birth rates. There is currently no role for low-molecular weight heparin to prevent late placental-mediated complications in patients with inherited thrombophilia and this may be due to small patient numbers in the studies involved in summarising the evidence. There is potential for low-molecular weight heparin to improve pregnancy outcomes in women with prior severe vascular complications of pregnancy such as early-onset intra-uterine growth restriction and pre-eclampsia but further high quality randomised controlled trials are required to answer this question.

The most common and serious complications of haemorrhoids include perianal thrombosis and incarcerated prolapsed internal haemorrhoids with subsequent thrombosis. They are characterised by severe pain in the perianal region possibly with bleeding. In a short history of the perianal thrombosis, acute surgical incision or excision is indicated, which can result in rapid relief of the painful symptoms. In incarcerated prolapsed internal haemorrhoids, emergency haemorrhoidectomy may also be indicated. Segmental haemorrhoidectomy in the most affected quadrants followed by further elective surgery for haemorrhoids in the next stage is preferred.

Hepatic complications contribute to morbidity and mortality after allogeneic hemopoietic SCT. Liver Doppler ultrasound and elastography represent promising methods for pretransplant risk assessment and early detection of complications. Ultrasound (liver and spleen size, liver perfusion) and elastography (transient elastography (TE); right liver lobe acoustic radiation force impulse imaging (r-ARFI); left liver lobe ARFI (l-ARFI)) were prospectively evaluated in patients with indications for allo-SCT. Measurements were performed before and repeatedly after SCT. Results were compared with the incidence of life-threatening complications and death during the first 150 days after SCT. Of 59 included patients, 16 suffered from major complications and 9 of them died within the follow-up period. At baseline, liver and spleen size, liver perfusion, TE and r-ARFI did not differ significantly between patients with and without severe complications. In contrast, l-ARFI was significantly elevated in patients who later developed severe complications (1.58±0.30 m/s vs 1.37±0.27 m/s, P=0.030). After SCT, l-ARFI values remained elevated and TE showed increasing liver stiffness in patients with complications. The value of conventional liver ultrasound for prediction of severe SCT complications is limited. Increased values for TE and l-ARFI are associated with severe SCT complications and demand further evaluation.
Full Text Available This experiment was conducted to investigate the effect of phytase superdoses alone or in combination with citric acid (CA in canola meal-based diets severely limited in available phosphorus (Pa on growth performance, plasma phosphorus (P, and tibia ash (TA in broilers from 22 to 42 d of age. Two hundreds and eighty 21-d-old male broilers were used in 28 pens of 10 birds per each. The experimental diets consisted of a positive control (PC diet and six negative control (NC diets which consisted of two levels of CA (0 and 20 g/Kg and three levels of phytase (0, 1000 and 4000 U/Kg in a 2 × 3 factorial arrangement. The PC diet contained 4.3 g/Kg Pa, but all NC diets contained 1.5 g/Kg Pa. Results indicated that the birds fed the PC diet had a significantly higher average daily gain (ADG, plasma P and TA, but a lower feed conversion ratio (FCR than those fed the NC diet. The ADG, FCR and plasma P values in birds fed NC diets supplemented with 4000 U/Kg phytase enzyme (with or without CA significantly reached those of birds fed the PC diet. But, addition of phytase enzyme at 1000 U/Kg only plus CA to the NC diet could significantly improve FCR and plasma P. A significant interaction was observed between phytase and CA for FCR and plasma P. Although TA values in NC + 1000 U/Kg phytase treatments (with or without CA were similar to the PC treatment, TA values of NC + 4000 U/Kg phytase treatments (with or without CA was greater than that of the PC treatment. Results of this study showed that, in severely limited Pa corn-canola meal-based diets, supplementing 4000 U/Kg phytase or also 1000 U/Kg phytase plus CA will be sufficient to obtain the comparable feed efficiency in broilers to those fed the adequate Pa diet.

SUMMARY We examined whether exogenous glucose affects contractile performance of electrically paced ventricle strips from rainbow trout under conditions known to alter cardiomyocyte performance, ion regulation and energy demands. Physiological levels of d-glucose did not influence twitch force development for aerobic preparations (1) paced at 0.5 or 1.1 Hz, (2) at 15 or 23°C, (3) receiving adrenergic stimulation or (4) during reoxygenation with or without adrenaline after severe hypoxia. Contractile responses to ryanodine, an inhibitor of Ca2+ release from the sarcoplasmic reticulum, were also not affected by exogenous glucose. However, glucose did attenuate the fall in twitch force during severe hypoxia. Glucose uptake was assayed in non-contracting ventricle strips using 2-[3H] deoxy-d-glucose (2-DG) under aerobic and hypoxic conditions, at different incubation temperatures and with different inhibitors. Based upon a lack of saturation of 2-DG uptake and incomplete inhibition of uptake by cytochalasin B and d-glucose, 2-DG uptake was mediated by a combination of facilitated transport and simple diffusion. Hypoxia stimulated lactate efflux sixfold to sevenfold with glucose present, but did not increase 2-DG uptake or reduce lactate efflux in the presence of cytochalasin B. Increasing temperature (14 to 24°C) also did not increase 2-DG uptake, but decreasing temperature (14 to 4°C) reduced 2-DG uptake by 45%. In conclusion, exogenous glucose improves mechanical performance under hypoxia but not under any of the aerobic conditions applied. The extracellular concentration of glucose and cold temperature appear to determine and limit cardiomyocyte glucose uptake, respectively, and together may help define a metabolic strategy that relies predominantly on intracellular energy stores.

Full Text Available Abstract Background This study describes the continuation of a program to constrain health care costs by limiting inpatient hospital programs among the hospitals of Syracuse, New York. Through a community demonstration project, it identified components of individual hospital programs for reduction of complications and their impact on the frequency and rates of these outcomes. Findings This study involved the implementation of interventions by three hospitals using the Potentially Preventable Complications System developed by 3M™ Health Information Systems. The program is noteworthy because it included competing hospitals in the same community working together to reduce adverse patient outcomes and related costs. The study data identified statistically significant reductions in the frequency of high and low volume complications during the three year period at two of the hospitals. At both of these hospitals, aggregate complication rates also declined. At these hospitals, the differences between actual complication rates and severity adjusted complication rates were also reduced. At the third hospital, specific and aggregate complication rates remained the same or increased slightly. Differences between these rates and those of severity adjusted comparison population also remained the same or increased. Conclusions Results of the study suggested that, in one community health care system, the progress of reducing complications involved different experiences. At two hospitals with relatively higher rates at the beginning of the study, management by administrative and clinical staff outside quality assurance produced significant reductions in complication rates, while at a hospital with lower rates, management by quality assurance staff had little effect on reducing the rate of PPCs.
study assessed the efficacy and safety of once-daily inhaled indacaterol 150 µg for the treatment of Korean COPD patients with destroyed lung by TB and moderate-to-severe airflow limitation. Methods: This was a multicenter, double-blind, parallel-group study, in which eligible patients were randomized (1:1 to receive either once-daily indacaterol 150 µg or placebo for 8 weeks. The primary efficacy endpoint was change from baseline in trough forced expiratory volume in 1 s at Week 8; the secondary endpoints included changes in transition dyspnea index score and St George’s Respiratory Questionnaire for COPD score at Week 8. Safety was evaluated over 8 weeks. Results: Of the 136 patients randomized, 119 (87.5% completed the study treatment. At Week 8, indacaterol significantly improved trough forced expiratory volume in 1 s versus placebo (treatment difference [TD] 140 mL, P<0.001. Statistically significant improvement in transition dyspnea index score (TD =0.78, P<0.05 and numerical improvement in St George’s Respiratory Questionnaire for COPD score (TD =-2.36, P=0.3563 were observed with indacaterol versus placebo at Week 8. Incidence of adverse events was comparable between the treatment groups. Conclusion: Indacaterol provided significantly superior bronchodilation, significant improvement in breathlessness and improved health status with comparable safety versus placebo in Korean COPD patients with destroyed lung by TB and moderate-to-severe airflow limitation.

A wide spectrum of pulmonary complications occurs in patients with pneumoconiosis. Those complications include chronic obstructive pulmonary disease, hemoptysis, pneumothorax, pleural disease, tuberculosis, autoimmune disease, anthracofibrosis, chronic interstitial pneumonia, and malignancy. Generally, imaging workup starts with plain chest radiography. However, sometimes, plain radiography has limited role in the diagnosis of pulmonary complications of pneumoconiosis because of overlapping pneumoconiotic infiltration. Computed tomography (CT), ultrasonography (US), and magnetic resonance imaging (MRI) are potentially helpful for the detection of pulmonary complications in patients with pneumoconiosis. CT, with its excellent contrast resolution, is more sensitive and specific method than plain radiograph in the evaluation of pulmonary abnormalities. CT is useful in detecting lung parenchymal abnormalities caused by infection, anthracofibrosis, and chronic interstitial pneumonia. Also, CT is valuable in distinguishing localized pneumothorax from bullae and aiding the identification of multiloculated effusions. US can be used in detection of complicated pleural effusions and guidance of the thoracentesis procedure. MRI is useful for differentiating between progressive massive fibrosis and lung cancer. Radiologists need to be familiar with the radiologic and clinical manifestations of, as well as diagnostic approaches to, complications associated with pneumoconiosis. Knowledge of the various imaging features of pulmonary complications of pneumoconiosis can enhance early diagnosis and improve the chance to cure

Purpose: Severe (Radiation Therapy Oncology Group [RTOG] grade 3 or greater) esophagitis generally occurs in 15% to 25% of non–small cell lung cancer (NSCLC) patients undergoing concurrent chemotherapy and radiation therapy (CCRT), which may result in treatment breaks that compromise local tumor control and pose a barrier to dose escalation. Here, we report a novel contralateral esophagus-sparing technique (CEST) that uses intensity modulated radiation therapy (IMRT) to reduce the incidence of severe esophagitis. Methods and Materials: We reviewed consecutive patients with thoracic malignancies undergoing curative CCRT in whom CEST was used. The esophageal wall contralateral (CE) to the tumor was contoured as an avoidance structure, and IMRT was used to guide a rapid dose falloff gradient beyond the target volume in close proximity to the esophagus. Esophagitis was recorded based on the RTOG acute toxicity grading system. Results: We identified 20 consecutive patients treated with CCRT of at least 63 Gy in whom there was gross tumor within 1 cm of the esophagus. The median radiation dose was 70.2 Gy (range, 63-72.15 Gy). In all patients, ≥99% of the planning and internal target volumes was covered by ≥90% and 100% of prescription dose, respectively. Strikingly, no patient experienced grade ≥3 esophagitis (95% confidence limits, 0%-16%) despite the high total doses delivered. The median maximum dose, V45, and V55 of the CE were 60.7 Gy, 2.1 cc, and 0.4 cc, respectively, indicating effective esophagus cross-section sparing by CEST. Conclusion: We report a simple yet effective method to avoid exposing the entire esophagus cross-section to high doses. By using proposed CE dose constraints of V45 <2.5 cc and V55 <0.5 cc, CEST may improve the esophagus toxicity profile in thoracic cancer patients receiving CCRT even at doses above the standard 60- to 63-Gy levels. Prospective testing of CEST is warranted

Morbid obesity is strongly associated with nonalcoholic fatty liver disease (NAFLD), which is one of the most common causes of chronic liver disease worldwide. The present best treatment for NAFLD and nonalcoholic steatohepatitis (NASH) is weight reduction through lifestyle modification. Because of frustrating inefficiency of such a therapeutic approach, bariatric surgery is increasingly performed in adolescents as an alternative option for weight reduction. Standards of care and consensus for indications are, however, scarce. We explore the indications and limitations of bariatric surgery in children with severe obesity with and without NASH and aim to provide guidance for the exceptional indications for adolescents with extreme obesity with major comorbidity that may benefit from these controversial interventions. Present evidence suggests that bariatric surgery can decrease the grade of steatosis, hepatic inflammation, and fibrosis in NASH. Uncomplicated NAFLD is not an indication for bariatric surgery. Roux-en-Y gastric bypass is considered a safe and effective option for adolescents with extreme obesity, as long as an appropriate long-term follow-up is provided. Laparoscopic adjustable gastric banding has not been approved by the Food and Drug Administration for use in adolescents and therefore should be considered investigational. Finally, sleeve gastrectomy and other types of weight loss surgery that have grown increasingly common in adults, still need to be considered investigational. Temporary devices may be increasingly being used in pediatrics; however, future studies, including a long-term risk analysis of patients who undergo surgery, are much needed to clarify the exact indications for bariatric surgery in adolescents.

An increasing body of evidence suggests the likelihood of a link between venous and arterial thrombosis. The two vascular complications share several risk factors, such as age, obesity, smoking, diabetes mellitus, blood hypertension, hypertriglyceridemia, and metabolic syndrome. Moreover, there are many examples of conditions accounting for both venous and arterial thrombosis, such as the antiphospholipid antibody syndrome, hyperhomocysteinemia, malignancies, infections, and the use of hormonal treatment. Finally, several recent studies have consistently shown that patients with venous thromboembolism are at a higher risk of arterial thrombotic complications than matched control individuals. We, therefore, speculate the two vascular complications are simultaneously triggered by biological stimuli responsible for activating coagulation and inflammatory pathways in both the arterial and the venous system. Future studies are needed to clarify the nature of this association, to assess its extent, and to evaluate its implications for clinical practice.

Traumatic rib fractures are associated with significant morbidity. Vital capacity (VC) assesses pulmonary function; however, limited data link VC to patient outcomes. Our objective was to determine if VC predicted complications and disposition in patients with rib fractures. This is a retrospective chart review of all patients with fractured ribs admitted to a Level 1 trauma center during a 4-year period. Patients were excluded if no VC was performed within 48 hours of admission. Data collected included demographics, hospital/intensive care unit length of stay, epidural, discharge to home versus extended care facility, mortality, chest Abbreviated Injury Scale (AIS) score, Injury Severity Score (ISS), number of rib fractures, hemothorax/pneumothorax, presence of pulmonary contusion, presence of chest tube, chronic obstructive pulmonary disease, and average daily VC (percentage of predicted). Pulmonary complication was defined as pneumonia, need for intubation, new home O2 requirement, readmission for pulmonary issue, or intensive care unit transfer. Statistical analysis was performed using χ and multivariate logistic regression. Of 801 patients with rib fractures, 683 had VC performed within 48 hours. Average age was 53 years, median ISS was 13 (interquartile range, 9-18), and median length of stay was 5 days. Most (72%) were discharged home, and 26% went to extended care facility. Ten percent developed a pulmonary complication, and there were nine deaths. Every 10% increase in VC was associated with 36% decrease in likelihood of pulmonary complication. Patients with a VC greater than 50% had a significantly lower association of pulmonary complication (p = 0.017), and a VC of less than 30% was independently associated with pulmonary complication (odds ratio, 2.36). Patients with fractured ribs and VC of less than 30% have significant association for pulmonary complication. Higher VC is associated with lower likelihood of pulmonary complication. VC may help

1. Two trials were conducted to evaluate the effect of high-dose phytase alone or in combination with citric acid (CA) in the diet severely limited in available phosphorus (P) on performance, plasma P and plasma Ca of broilers from 22 to 42 d of age. 2. In Trial 1, 297 21-d-old female chicks were placed into 27 pens and allocated to 9 maize-soybean meal-based dietary treatments, which were a positive control [PC, 4.23 g/kg non-phytate P (NPP)] and 8 negative control (NC, 1.35 g/kg NPP) groups consisting of two concentrations of CA (0 and 20 g/kg) and 4 concentrations of phytase (0, 1000, 2000 and 4000 U/kg) in a 2 × 4 factorial arrangement. In Trial 2, 192 21-d-old male chicks were placed into 24 pens and allocated to 6 wheat-canola meal-based dietary treatments, which were a PC (4.2 g/kg NPP), a NC (1.68 g/kg NPP) and 4 NC groups consisting of two concentrations of CA (0 and 20 g/kg) and two concentrations of phytase (2000 and 4000 U/kg) in a 2 × 2 factorial arrangement. 3. In both trials, birds fed on the PC had significantly higher average daily gain (ADG), average daily feed intake (ADFI), plasma P and lower feed conversion ratio (FCR) and plasma Ca than those of birds fed on the NC. CA supplementation significantly increased ADG and ADFI. There was a significant interaction between CA and phytase on plasma P where CA improved the effect of phytase on plasma P. In Trial 1, phytase addition improved ADG, ADFI, FCR and plasma Ca linearly. 4. Briefly, this research showed the interaction effect between CA and phytase on plasma P when broilers were fed on diets based on maize-soybean meal or wheat-canola meal. The results showed that CA supplementation lowered the concentration of phytase that is needed in low NPP diets to increase plasma P.

1. Two trials were conducted from 22 to 42 d post-hatch to evaluate the effectiveness of high concentrations of supplemental phytase in maize-soya bean meal-based diets severely limited in available phosphorus (P). Growth performance, plasma P and tibia ash (TA) were measured. 2. Each trial used 220 21-d-old male broilers in 20 pens with 11 birds per pen. Dietary treatments included a positive control [PC, 4.3 g/kg nonphytate P (NPP)], negative control [NC, 2.3 g/kg NPP (Trial 1) or 1.4 g/kg NPP (Trial 2)] and NC plus 1000, 2000 or 4000 phytase U/kg of the diet. 3. Birds fed on the PC diet had higher average daily gain (ADG), gain to feed ratio (G:F), plasma P (Trials 1 and 2) and TA (Trial 2) than those fed on the NC. 4. In Trial 1, ADG and G:F values of the NC plus 1000, 2000 or 4000 phytase U/kg reached those of the PC. Plasma P values of the NC plus 2000 or 4000 phytase U/kg reached that of the PC. Although TA values of the NC, NC + 1000 or NC + 2000 reached that of the PC, TA of the NC + 4000 was more than that of the PC. 5. In Trial 2, ADG and G:F values of the NC plus 4000 phytase U/kg reached those of the PC; nevertheless, plasma P values of the NC diets did not come up to that of the PC. While TA values of the NC, NC + 1000 or NC + 2000 did not reach that of the PC, TA of the NC + 4000 was greater than that of the PC. 6. Results of this study showed that, in the diets with 2.3 and 1.4 g/kg NPP, respectively, 1000 and 4000 phytase U/kg can be sufficient to obtain a comparable performance in broilers to those given diets adequate in available P.

Acromegaly is associated with an enhanced mortality, with cardiovascular and respiratory complications representing not only the most frequent comorbidities but also two of the main causes of deaths, whereas a minor role is played by metabolic complications, and particularly diabetes mellitus. The most prevalent cardiovascular complications of acromegaly include a cardiomyopathy, characterized by cardiac hypertrophy and diastolic and systolic dysfunction together with arterial hypertension, cardiac rhythm disorders and valve diseases, as well as vascular endothelial dysfunction. Biochemical control of acromegaly significantly improves cardiovascular disease, albeit completely recovering to normal mainly in young patients with short disease duration. Respiratory complications, represented mainly by sleep-breathing disorders, particularly sleep apnea, and respiratory insufficiency, frequently occur at the early stage of the disease and, although their severity decreases with disease control, this improvement does not often change the indication for a specific therapy directed to improve respiratory function. Metabolic complications, including glucose and lipid disorders, are variably reported in acromegaly. Treatments of acromegaly may influence glucose metabolism, and the presence of diabetes mellitus in acromegaly may affect the choice of treatments, so that glucose homeostasis is worth being monitored during the entire course of the disease. Early diagnosis and prompt treatment of acromegaly, aimed at obtaining a strict control of hormone excess, are the best strategy to limit the development or reverse the complications and prevent the premature mortality.

Currently, a lot of space and time is devoted to the therapy of oncologic diseases itself. To reach the good therapy results, complex care of the oncologic patient is needed. Management of complications linked with the disease itself and management of complications emerged after administration of chemotherapy, radiotherapy or targeted therapy, plays a significant role. In addition to infectious, hematological, neurological, cardiac or other complications, metabolic complications are relatively extensive and serious. One of the most frequent metabolic complications in oncology is tumor lysis syndrome, hyperuricemia, hypercalcaemia and syndrome of inappropriate secretion of antidiuretic hormone. (author)

Bariatric surgery is now frequently proposed for the treatment of morbid or complicated obesity since the introduction of minimally invasive laparoscopic anti-obesity operations such as the adjustable silicone gastric binding gastroplasty. However this reversible procedure in not always as safe as presumed and the results in weight loss may be sometimes disappointing. Side effects are common and early or late complications occured in more than 20% out of the patients. They are favoured by post operative eating disorders. Nutritional consequences are probably underestimated and are not limited to uncomfortable digestive symptoms. Some deficiencies in micronutriments have been described. The worsening of previous eating disorders or psychosocial abnormalities are not seldom. Gastroplasty is not an harmless procedure. A good selection in patients, a regular follow up, nutritional advices and psychosocial management by a multidisciplinar team are required to reduce complications after gastroplasty.

The purpose of this systematic review was to address the incidence of complications associated with wrist arthroscopy. Given the paucity of information published on this topic, an all-inclusive review of published wrist arthroscopy complications was sought. Two independent reviewers performed a literature search using PubMed, Google Scholar, EBSCO, and Academic Megasearch using the terms "wrist arthroscopy complications," "complications of wrist arthroscopy," "wrist arthroscopy injury," and "wrist arthroscopy." Inclusion criteria were (1) Levels I to V evidence, (2) "complication" defined as an adverse outcome directly related to the operative procedure, and (3) explicit description of operative complications in the study. Eleven multiple-patient studies addressing complications of wrist arthroscopy from 1994 to 2010 were identified, with 42 complications reported from 895 wrist arthroscopy procedures, a 4.7% complication rate. Four case reports were also found, identifying injury to the dorsal sensory branch of the ulnar nerve, injury to the posterior interosseous nerve, and extensor tendon sheath fistula formation. This systematic review suggests that the previously documented rate of wrist arthroscopy complications may be underestimating the true incidence. The report of various complications provides insight to surgeons for improving future surgical techniques. Level IV, systematic review of Levels I-V studies.

In spite of improvements in single or double lung transplantation (LT) technique, complications after LT are not uncommon; the most frequent ale anastomotic complications, infections and rejection (acute or chronic). Early detection of complications of LT allows the optimal therapeutic option to be taken, yielding decreased morbidity and mortality. In some cases, CT plays a key role in early detection of several complications of LT that may not be depicted with other diagnostic modalities, so that knowledge of their CT features is important. In this pictorial review, the authors describe the spectrum of CT features of the complications of LT (including reimplantation response, mechanical problems, acute and chronic rejection, infection, lymphoproliferative disorders, recurrence of the initial disease and complications involving the pleura and the anastomotic sites). In addition, the authors analyze the value of CT compared to that of the other available modalities for the detection of complications of LT. (orig.). With 19 figs

Thyroid storm is a rare but potentially life-threatening complication of hyperthyroidism. Early recognition and prompt treatment are essential. Atrial fibrillation can occur in up to 40% of patients with thyroid storm. Studies have shown that hyperthyroidism increases the risk of thromboembolic events. There is no consensus with regard to the initiation of anticoagulation for atrial fibrillation in severe thyrotoxicosis. Anticoagulation is not routinely initiated if the risk is low on a CHADS2 score; however, this should be considered in patients with thyroid storm or severe thyrotoxicosis with impending storm irrespective of the CHADS2 risk, as it appears to increase the risk of thromboembolic episodes. Herein, we describe a case of thyroid storm complicated by massive pulmonary embolism. Diagnosis of thyroid storm is based on clinical findings. Early recognition and prompt treatment could lead to a favourable outcome.Hypercoagulable state is a recognised complication of thyrotoxicosis.Atrial fibrillation is strongly associated with hyperthyroidism and thyroid storm.Anticoagulation should be considered for patients with severe thyrotoxicosis and atrial fibrillation irrespective of the CHADS2 score.Patients with severe thyrotoxicosis and clinical evidence of thrombosis should be immediately anticoagulated until hyperthyroidism is under control.

We report the case of a 54-year-old hypertensive female who was admitted to the hospital with seizure episode and subsequently diagnosed to have severe hyponatremia due to SSRI-induced syndrome of inappropriate antidiuretic hormone (SIADH with the cause attributed to the short history of intake of escitalopram for depression. All SSRIs, including escitalopram, can cause SIADH and should be used with caution in the depressive patients with regular monitoring of electrolytes, especially in the elderly.

Cosmetic surgery tourism characterizes a phenomenon of people traveling abroad for aesthetic surgery treatment. Problems arise when patients return with complications or need of follow-up care. To investigate the complications of cosmetic surgery tourism treated at our hospital as well as to analyze arising costs for the health system. Between 2010 and 2014, we retrospectively included all patients presenting with complications arising from cosmetic surgery abroad. We reviewed medical records for patients' characteristics including performed operations, complications, and treatment. Associated cost expenditure and Diagnose Related Groups (DRG)-related reimbursement were analyzed. In total 109 patients were identified. All patients were female with a mean age of 38.5 ± 11.3 years. Most procedures were performed in South America (43%) and Southeast (29.4%) or central Europe (24.8%), respectively. Favored procedures were breast augmentation (39.4%), abdominoplasty (11%), and breast reduction (7.3%). Median time between the initial procedure abroad and presentation was 15 days (interquartile range [IQR], 9) for early, 81.5 days (IQR, 69.5) for midterm, and 4.9 years (IQR, 9.4) for late complications. Main complications were infections (25.7%), wound breakdown (19.3%), and pain/discomfort (14.7%). The majority of patients (63.3%) were treated conservatively; 34.8% became inpatients with a mean hospital stay of 5.2 ± 3.8 days. Overall DRG-related reimbursement premiums approximately covered the total costs. Despite warnings regarding associated risks, cosmetic surgery tourism has become increasingly popular. Efficient patients' referral to secondary/tertiary care centers with standardized evaluation and treatment can limit arising costs without imposing a too large burden on the social healthcare system. 4. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

Peri-operative acute kidney injury is common, accounting for 30-40% of all in-hospital cases of acute kidney injury. It is associated with clinically significant morbidity and mortality even with what was hitherto regarded as relatively trivial increases in serum creatinine, and carries over a 12-fold relative risk of death following major abdominal surgery. Comorbid conditions such as diabetes, hypertension, liver disease and particularly pre-existing chronic kidney disease, as well as the type and urgency of surgery, are major risk factors for the development of postoperative acute kidney injury. As yet, there are no specific treatment options for the injured kidney, although there are several modifiable risk factors of which the anaesthetist should be aware. As well as the avoidance of potential nephrotoxins and appropriate volume balance, optimal anaesthetic management should aim to reduce the risk of postoperative renal complications. This may include careful ventilatory management and blood pressure control, as well as appropriate analgesic strategies. The choice of anaesthetic agent may also influence renal outcomes. Rather than concentrate on the classical management of acute kidney injury, this review focuses on the potential development of acute kidney injury peri-operatively, and the means by which this may be ameliorated. © 2018 The Association of Anaesthetists of Great Britain and Ireland.
Comprehensive management of patients receiving radiotherapy to the head and neck dictates that they have a thorough dental evaluation as part of their overall treatment planning. Early and appropriate patient education and dental treatment, along with careful management during and after radiotherapy, will significantly decrease the incidence and severity of complications, improve quality of life, and increase tolerance to therapy. 49 refs.; 16 figs.; 1 table

Vernal kerato-conjunctivitis (VKC) is an infrequent but serious form of allergic conjunctivitis common in warm and humid areas where air is rich in allergens. It affects both eyes asymmetrically. Although VKC is a self-limiting disease but visions affecting corneal complications influence the quality of life in school children. The aim of this study was to list the corneal complications due to this condition and to find out the extent of visual impairment among VKC patients. Methods: This cross-sectional study was conducted in the department of Ophthalmology, Benazir Bhutto Shaheed Hospital on 290 eyes of diagnosed cases of VKC. The diagnosis of VKC was made on the basis of history and examination. Visual acuity was recorded using Snellen's notation and visual impairment was classified according to World Health Organization classification for visual disabilities. Results: The mean age of presentation was 10.83+-6.13 years. There were 207 (71.4%) males and 83 (28.6%) females. Corneal scarring was observed in 59 (20.3%) eyes. Keratoconus was found to be in 17 (5.9%) eyes. Shield ulcer was detected in 09 (3.1%) eyes while 07 (2.4%) eyes had corneal neovascularization. Majority of the patients with visual loss had corneal scarring and the complication that led to severe visual loss in most of the eyes was Keratoconus. Conclusion: Vernal kerato-conjunctivitis in the presence of corneal complications is a sight threatening disease and can lead to severe visual impairment. (author)

Awake craniotomy is recognized as method that can decrease the frequency of neurological complications after surgery for gliomas located near eloquent brain regions. Unfortunately good neurological outcome can't be ensured even by using of this technique. This paper discusses reasons and possible ways of prevention of such complications. 162 awake craniotomies were performed in our clinic. 152 of patients were discharged from the clinic with good outcome. In 10 (6%) cases sustained severe neurological deficit was noted. These complications were associated with anatomic or ischemic injury of subcortical pathways and internal capsule. Awake craniotomy is effective instrument of brain language mapping and prevention of neurological deterioration. Severe neurological complications of awake craniotomy are associated with underestimate neurosurgical risks, especially in terms of blood vessel injury and depth of resection. The main way of prevention of such complications is meticulous planning of operation and adequate using of mapping facilities.

The colostomy may be terminal or lateral, temporary or permanent. It may have psychological, medical or surgical complications. reporting the incidence of surgical complications of colostomies, their therapeutic management and trying to identify risk factors for their occurrence. A retrospective study for a period of 5 years in general surgery department, Habib Bourguiba hospital, Sfax, including all patients operated with confection of a colostomy. Were then studied patients reoperated for stoma complication. Among the 268 patients who have had a colostomy, 19 patients (7%) developed surgical stoma complications. They had a mean age of 59 years, a sex ratio of 5.3 and a 1-ASA score in 42% of cases. It was a prolapse in 9 cases (reconfection of the colostomy: 6 cases, restoration of digestive continuity: 3 cases), a necrosis in 5 cases (reconfection of the colostomy), a plicature in 2 cases (reconfection of the colostomy) a peristomal abscess in 2 cases (reconfection of the colostomy: 1 case, restoration of digestive continuity: 1 case) and a strangulated parastomal hernia in 1 case (herniorrhaphy). The elective incision and the perineal disease were risk factors for the occurrence of prolapse stomial. Surgical complications of colostomies remain a rare event. Prolapse is the most common complication, and it is mainly related to elective approach. Reoperation is often required especially in cases of early complications, with usually uneventful postoperative course.

A framework methodology is proposed for streamflow prediction in poorly-gauged rivers located within large-scale regions of sparse hydrometeorologic observation. A multi-criteria model evaluation is developed to select models that balance runoff efficiency with selection of accurate parameter values. Sparse observed data are supplemented by uncertain or low-resolution information, incorporated as 'soft' data, to estimate parameter values a priori. Model performance is tested in two catchments within a data-poor region of southwestern China, and results are compared to models selected using alternative calibration methods. While all models perform consistently with respect to runoff efficiency (NSE range of 0.67-0.78), models selected using the proposed multi-objective method may incorporate more representative parameter values than those selected by traditional calibration. Notably, parameter values estimated by the proposed method resonate with direct estimates of catchment subsurface storage capacity (parameter residuals of 20 and 61 mm for maximum soil moisture capacity (Cmax), and 0.91 and 0.48 for soil moisture distribution shape factor (B); where a parameter residual is equal to the centroid of a soft parameter value minus the calibrated parameter value). A model more traditionally calibrated to observed data only (single-objective model) estimates a much lower soil moisture capacity (residuals of Cmax = 475 and 518 mm and B = 1.24 and 0.7). A constrained single-objective model also underestimates maximum soil moisture capacity relative to a priori estimates (residuals of Cmax = 246 and 289 mm). The proposed method may allow managers to more confidently transfer calibrated models to ungauged catchments for streamflow predictions, even in the world's most data-limited regions.

Over the past few years, a new topic in the field of endometriosis has emerged: the potential impact of the disease on pregnancy outcomes. This review aims to summarize in detail the available evidence on the relationship between endometriosis, particularly deep endometriosis (DE), and obstetrical outcomes. Acute complications of DE, such as spontaneous hemoperitoneum, bowel perforation, and uterine rupture, may occur during pregnancy. Although these events represent life-threatening conditions, they are rare and unpredictable. Therefore, the current literature does not support any kind of prophylactic surgery before pregnancy to prevent such complications. Results on the impact of DE on obstetrical outcomes are debatable and characterized by several limitations, including small sample size, lack of adjustment for confounders, lack of adequate control subjects, and other methodologic flaws. For these reasons, it is not possible to draw conclusions on this topic. The strongest evidence shows that DE is associated with higher rates of placenta previa; for other obstetrical outcomes, such as miscarriage, intrauterine growth restriction, preterm birth and hypertensive disorders, results are controversial. Although it is unlikely that surgery of DE may modify the impact of the disease on the course of pregnancy, no study has yet investigated this issue.

Osteochondroma is the most common entity beyond all the known osseous tumors. It is a lesion with a high enlargement capacity and a continuous growing in some cases, and it may determine complications, mainly due to mass effect. It may be present in a solitary or multiple forms, and the last one is related with a higher tendency to sarcomatous transformation, which is the most frightening complication. The purpose of the present study is to demonstrate, through an iconographic assay, the most common complications caused by the osteochondromas, making the correlation of its clinical and radiological aspects.

Although noninvasive techniques are often used to assess the effect of vasodilator therapy in patients with congestive heart failure, it is unknown whether changes in noninvasively determined left ventricular ejection fraction, volume, or dimension reliably reflect alterations in intracardiac pressure and flow. Accordingly, we compared the acute effect of sodium nitroprusside on left ventricular volume and ejection fraction (determined scintigraphically) with its effect on intracardiac pressure and forward cardiac index (determined by thermodilution) in 12 patients with severe, chronic congestive heart failure and a markedly dilated left ventricle. Nitroprusside (infused at 1.3 +/- 1.1 [mean +/- standard deviation] microgram/kg/min) caused a decrease in mean systemic arterial, mean pulmonary arterial, and mean pulmonary capillary wedge pressure as well as a concomitant increase in forward cardiac index. Simultaneously, left ventricular end-diastolic and end-systolic volume indexes decreased, but the scintigraphically determined cardiac index did not change significantly. Left ventricular ejection fraction averaged 0.19 +/- 0.05 before nitroprusside administration and increased by less than 0.05 units in response to nitroprusside in 11 of 12 patients. The only significant correlation between scintigraphically and invasively determined variables was that between the percent change in end-diastolic volume index and the percent change in pulmonary capillary wedge pressure (r . 0.68, p . 0.01). Although nitroprusside produced changes in scintigraphically determined left ventricular ejection fraction, end-systolic volume index, and cardiac index, these alterations bore no predictable relation to changes in intracardiac pressure, forward cardiac index, or vascular resistance. Furthermore, nitroprusside produced a considerably greater percent change in the invasively measured variables than in the scintigraphically determined ones

Complications of shoulder dystocia are divided into fetal and maternal. Fetal brachial plexus injury (BPI) is the most common fetal complication occurring in 4-40% of cases. BPI has also been reported in abdominal deliveries and in deliveries not complicated by shoulder dystocia. Fractures of the fetal humerus and clavicle occur in about 10.6% of cases of shoulder dystocia and usually heal with no sequel. Hypoxic ischemic brain injury is reported in 0.5-23% of cases of shoulder dystocia. The risk correlates with the duration of head-to-body delivery and is especially increased when the duration is >5 min. Fetal death is rare and is reported in 0.4% of cases. Maternal complications of shoulder dystocia include post-partum hemorrhage, vaginal lacerations, anal tears, and uterine rupture. The psychological stress impact of shoulder dystocia is under-recognized and deserves counseling prior to home discharge. Copyright © 2014 Elsevier Inc. All rights reserved.

Summary Background Recent developments in hip arthroscopic techniques and technology have made it possible in many cases to avoid open surgical dislocation for treating a variety of pathology in the hip. Although early reports suggest favourable results’ using hip arthroscopy and it has been shown to be a relatively safe procedure, complications do exist and can sometimes lead to significant morbidity. Methods This is a review article. The aim of this manuscript is to present the most frequent and/or serious complications that could occur at or following hip arthroscopy and some guidelines to avoid these complications. Conclusion Most complications of hip arthroscopy are minor or transient but serious complications can occur as well. A lot of complication e.g. acetabular labral puncture go unreported. Appropriate education and training, precise and meticulous surgical technique with correct instrumentation, the right indication in the right patient and adherence to advice from mentors and experienced colleagues are all essential factors for a successful outcome. Level of evidence: V. PMID:28066747
Full Text Available A 36-year-old woman who had been diagnosed with ulcerative colitis at the age of 17 years was referred to our hospital because of severe abdominal pain and repeated bloody diarrhea that persisted during pregnancy despite combination therapy with high-dose corticosteroids and weekly granulocyte and monocyte adsorptive apheresis (GMA. She underwent combination therapy consisting of high-dose corticosteroids, intensive GMA (two sessions per week and vancomycin, which was used to eradicate Clostridium difficile, under total parenteral nutrition control until the estimated weight of her fetus reached 1,000 g. This combination therapy was partially successful, resulting in almost complete disappearance of abdominal pain and a marked decrease in stool frequency. However bloody diarrhea persisted and the patient developed anemia and hypoalbuminemia and was unable to prolong her gestation time. Cesarean section was conducted at 28 weeks of gestation without any congenital abnormalities or neurological defects. Oral administration of tacrolimus was begun 7 days after cesarean section, which was followed by rapid induction of remission. Corticosteroids were then gradually tapered off. Tacrolimus is one therapeutic option after cesarean section in pregnant patients who do not respond well to GMA and high-dose corticosteroids for persistent active ulcerative colitis.

To report the complications observed in a consecutive large series of cases treated with keratopigmentation (KTP). KTP was performed in 234 eyes of 204 patients for therapeutic and cosmetic reasons. From them, 50 eyes of 29 patients suffered complications. Different KTP techniques and three generations of pigments (GP) were used. The follow-up period ranged from 4 months to 12 years. Light sensitivity (LS), visual field (VF) limitations and MRI alterations were considered functional complications. Organic complications were described as change in colour, colour fading and neovascularisation. The percentage of complications was 12.82%. Most patients complained of LS (49%), then colour fading and change in colour (19%). Neovascularisation, VF limitations and MRI complications constituted 7%, 4% and 2%, respectively. Organic complications were observed with the previous GP but resolved with the latest third GP with CE mark certification (Conformité Européene). Although LS remained with the corneal-specific pigments, it gradually disappeared in most of the patients (81.81%) 6 months postoperatively. To the best of our knowledge this is the first time a study systematically and comprehensively approaches and reports KTP complications. KTP with third GP provides better results and fewer complications than previous ones. It is a modern, minimally invasive technique that helps solve several functional ocular problems and improves cosmetic appearance of the patients. Dermatological pigments should not be used as they lead to complications; instead pigments specifically tested for the eye in terms of toxicity and teratogenicity should be used. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Full Text Available Objective: To investigate the incidence and etiology of pregnancy complications associated with thrombophilic factors. Methods: Fifty-four patients with complicated pregnancy and 40 healthy pregnant subjects were included the study. Factor V Leiden (FVL mutation, protein S, protein C, anti-thrombin deficiency levels were investigated. Results: Of the 54 patients with complicated pregnancy, 29 had preeclampsia, 18 had intra uterine growth retardation, and 7 had intrauterine fetal loss. The most common defect was FVL mutation. FVL mutations in patient group and the control group were 27.2% and 10%, respectively, which were statistically significant. The protein S, protein C, and anti-thrombin deficiencies were found higher in the patient group compared to control (p>0.05 for each. Conclusion: FVL mutation was found higher in patient group compared to the control group, Protein C deficiency and anti-thrombin deficiency were related to preeclampsia but not other pregnancy complications. Clinicians should take into account the thrombophilia in complicated pregnancy, especially preeclampsia. J Clin Exp Invest 2013; 4 (4: 497-502

Much is written about how difficult it is to deal with diabetes during adolescence, and rightly so. Less is understood as to how puberty may be an accelerator of vascular complications. With the increase in childhood diabetes, complication risks need to be revisited in relation to puberty and the secular increase in adiposity. Recent data suggest greater risk for severe vascular complications in those with diabetes during puberty, compared with young people who develop diabetes after puberty. It is also widely recognized that higher hemoglobin A1c (HbA1c) results are often seen during the pubertal period. This article will review complication outcomes in relation to puberty and examine mechanisms by which puberty may modify risk above glycemic exposure, and possible gender disparities in the risk of complications in the adolescent period. © 2014 John Wiley & Sons A/S.

To evaluate the association between time of postpartum discharge and symptoms indicative of complications during the first postpartum week. Women with vaginal delivery at a Mexico City public hospital, without complications before the hospital discharge, were interviewed seven days after delivery. Time of postpartum discharge was classified as early (25 hours). The dependent variable was defined as the occurrence and severity of puerperal complication symptoms. Out of 303 women, 208 (68%) were discharged early. However, women with early discharge and satisfactory prenatal care had lower odds of presenting symptoms in early puerperium than women without early discharge and inadequate prenatal care (OR 0.36; 95% confidence intervals = 0.17-0.76). There was no association between early discharge and symptoms of complications during the first postpartum week; the odds of complications were lower for mothers with early discharge and satisfactory prenatal care.
Full Text Available Dengue infection is highly endemic in many tropical countries including Malaysia. However, neurological complications arising from dengue infection is not common; Gullain–Barre syndrome (GBS is one of these infrequent complications. In this paper, we have reported a case in which a 39-year-old woman presented with a neurological complication of dengue infection without typical symptoms and signs of dengue fever. She had a history of acute gastroenteritis (AGE followed by an upper respiratory tract infection (URTI weeks prior to her presentation rendering GBS secondary to the post viral URTI and AGE as the most likely diagnosis. Presence of thrombocytopenia was the only clue for dengue in this case.

Full Text Available Introduction. Chronic pancreatitis (CP is considered an inflammatory disease that may cause varying degrees of pancreatic dysfunction. Conservative and surgical treatment options are available depending on dysfunction severity. Presentation of Case. A 36-year-old male with history of heavy alcohol consumption and diagnosed CP underwent a duodenal-preserving pancreatic head resection (DPPHR or Beger procedure after conservative treatment failure. Refractory pain was reported on follow-up three months after surgery and postoperative imaging uncovered stones within the main pancreatic duct and intestinal dilation. The patient was subsequently subjected to another surgical procedure and intraoperative findings included protein plugs within the main pancreatic duct and pancreaticojejunal anastomosis stricture. A V-shaped enlargement and main pancreatic duct dilation in addition to the reconstruction of the previous pancreaticojejunal anastomosis were performed. The patient recovered with no further postoperative complications in the follow-up at an outpatient clinic. Discussion. Main duct and pancreaticojejunal strictures are an unusual complication of the Beger procedure but were identified intraoperatively as the cause of patient’s refractory pain and explained intraductal protein plugs accumulation. Conclusion. Patients that undergo Beger procedures should receive close outpatient clinical follow-up in order to guarantee postoperative conservative treatment success and therefore guarantee an early detection of postoperative complications.

Cosmetic tattoos, which are better known as permanent make-up, have become popular in the last decades. This same procedure can be used to camouflage pathological skin conditions, to mask scars and to complete the aesthetic results of plastic and reconstructive surgeries. The risks and complications of tattooing procedures include infections and allergic reactions. Scarring can occur. Fanning and fading of the colorants and dissatisfaction with colour and shape are not unusual. Different lasers can offer solutions for the removal of unwanted cosmetic tattoos, but complications due to the laser treatment, such as paradoxical darkening and scarring, can arise. © 2015 S.

Acute pancreatitis varies from a mild, self-limited disease to one with significant morbidity and mortality in its most severe forms. While clinical criteria abound, imaging has become indispensable to diagnose the extent of the disease and its complications, as well as to guide and monitor therapy. Percutaneous interventional techniques offer options that can be life-saving, surgery-sparing or important adjuncts to operation. Close cooperation and communication between the surgeon, gastroenterologist and interventional radiologist enhance the likelihood of successful patient care

There is a paucity of experience in the published literature documenting complications of powered surgical instruments in laryngologic surgery. Our objective was to ascertain the nature of these complications from expert opinion and review of the literature, and to recommend strategies to decrease major complications. Review of the literature and an e-mail survey. A literature review of microdebrider complications in laryngologic surgery was conducted using PubMed and Ovid (1985 to 2013), along with an analysis of a confidential e-mail survey of various surgeons in selected high-volume laryngologic centers. Powered instrumentation is frequently used in the operating room for larynx and airway surgery. The microdebrider can improve efficiency, lower costs, and shorten operative times. However, use of the microdebrider has the potential for serious complications in the larynx and airway. Great care must be taken when utilizing the microdebrider in laryngologic surgery. Significant complications including major vocal fold scar, airway compromise, severe hemorrhage, and unintentional tissue loss have occurred. The microdebrider is a popular and valuable tool for the otolaryngologist. A thorough knowledge of the instrument and its potential complications will improve surgical outcomes and may prevent complications. Awareness of the risks and surgeon experience with use of the microdebrider will allow the surgeon to successfully utilize this device in a safe and effective manner. 5. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Anorexia nervosa and bulimia nervosa are serious psychiatric illnesses related to disordered eating and distorted body images. They both have significant medical complications associated with the weight loss and malnutrition of anorexia nervosa, as well as from the purging behaviors that characterize bulimia nervosa. No body system is spared from the adverse sequelae of these illnesses, especially as anorexia nervosa and bulimia nervosa become more severe and chronic. We review the medical complications that are associated with anorexia nervosa and bulimia nervosa, as well as the treatment for the complications. We also discuss the epidemiology and psychiatric comorbidities of these eating disorders. Copyright © 2016 Elsevier Inc. All rights reserved.

Percutaneous interventional therapy plays an important role in treating complications of acute and chronic pancreatitis. With the development of cross-sectional imaging and advanced interventional techniques, percutaneous drainage has become the preferred treatment for pancreatic fluid collections such as acute collections, pseudocysts and abscesses. Abscess and pancreatic hemorrhage are the most life threatening complications of pancreatitis. Massive hemorrhage is rare but frequently lethal. As a rule, bleeding complications of pancreatitis require prompt diagnosis and an aggressive surgical approach. In unstable patients with a severely bleeding pseudoaneurysm, hemostasis can be obtained by occlusion with mechanical devices.

The rising popularity of surgery involving the laryngeal framework (surgical medialization of immobile vocal folds, vocal fold tightening, pitch variation, etc.) has resulted in increasing case experience. Little has appeared in the literature regarding complications or long-term results of this type of surgery. Several years' experience in a major referral center with various types of laryngeal framework surgery has led to a small number of complications. These have included late extrusion of the prosthesis and delayed hemorrhage. A review of these complications and recommendations for modification of technique to minimize them in the future are discussed.

The prevalence of severe coronary artery disease in peripheral vascular patients exceeds 50 per cent. Complications of coronary artery disease are the most common causes of mortality following peripheral vascular operations. To reduce the incidence of cardiac complications, it is first necessary to identify patients at risk through screening tests. Screening methods in current use include risk factor analysis, exercise testing, routine coronary angiography, and dipyridamole thallium-201 scintigraphy. The risk factor approach has the advantage of being widely applicable since it makes use of historical, physical, and electrocardiographic findings that are already familiar to surgeons and anesthesiologists. It is also inexpensive. However, it may overlook the patient who has no symptoms of coronary artery disease, possibly as a result of the sedentary lifestyle imposed by complications of peripheral vascular disease. The electrocardiographically monitored stress test will identify the asymptomatic patient with occult coronary disease and is helpful in predicting operative risk. However, a meaningful test is dependent on the patient's ability to exercise--an activity that is frequently limited by claudication, amputation, or arthritis. Exercise testing also suffers from a lack of sensitivity and specificity when compared with coronary arteriography. Routine preoperative coronary angiography overcomes the exercise limitation of treadmill testing but is not widely applicable as a screening test for reasons of cost and inherent risk. Dipyridamole thallium-201 scanning, on the other hand, is safe and of relatively low cost and does not require exercise
Full Text Available Intramural hematoma of the esophagus is a rare injury causing esophageal mucosal dissection. Forceful vomiting and coagulopathy are common underlying causes in the elderly population taking antiplatelets or anticoagulation agents. Acute retrosternal pain followed by hematemesis and dysphagia differentiates the hematoma from other cardiac or thoracic emergencies, including acute myocardial infarction or aortic dissection. Direct inspection by endoscopy is useful, but chest computed tomography best assesses the degree of obliteration of the lumen and excludes other differential diagnoses. Intramural hematoma of the esophagus is generally benign and most patients recover fully with conservative treatment. Bleeding can be managed medically unless in hemodynamically unstable patients, for whom surgical or angiographic treatment may be attempted; only rarely esophageal obstruction requires endoscopic decompression. We report an unusual case of esophageal hematoma, presenting in a young preeclamptic woman after surgical delivery of a preterm twin pregnancy, with a favorable outcome following medical management.

Numerous complications and increased operating times were reported with ultrasonically assisted lipoplasty in the first several months after introduction of the technology in the United States. The purpose of this study was to review early reported complications and management regimens, evaluate possible causes of problems, and apply indications and techniques to attempt to minimize complications during an initial experience with this technique beginning in January of 1997. Seven specific indications and modifications of existing techniques were developed and applied to an initial clinical series of 70 consecutive patients who underwent ultrasound-assisted suction lipoplasty between January 10, 1997, and August 1, 1997. Follow-up ranged from 1 to 7 months. No perioperative or postoperative complication occurred in any patient in this series. In this series of ultrasound-assisted lipoplasty cases, application of the following criteria resulted in a series of 70 patients with 1 to 7-month follow-up without complications: (1) selecting patients with well localized fat deposits who were no more than 20 percent above their ideal body weight; (2) infusing a solution of Ringer's Lactate containing 1 cc of 1:1000 epinephrine per 1000 cc into the area of fat removal, stopping infusion when the tissues first become firm, not infusing to marked tissue turgor or skin induration; (3) restricting the level of energy application to a minimum of 1 cm from the undersurface of the dermis; (4) limiting ultrasonic energy application in each area to approximately 1 minute per estimated 100 cc of total aspirate in a wet to superwet environment; (5) not performing ultrasound-assisted lipoplasty in the same area as another procedure that could potentially compromise tissue vascularity; (6) using a Lysonix 2000 generator and 5-mm golf tee tip probe at a power setting of 8 to apply ultrasonic energy to the area of fat removal, ceasing energy application when tissue resistance to the passage

There are cases in which, although all traces of acute radiation complications seem to have disappeared, late complications may appear months or years to become apparent. Trauma, infection or chemotherapy may sometimes recall radiation damage and irreversible change. There were two cases of breast cancer that received an estimated skin dose in the 6000 cGy range followed by extirpation of the residual tumor. The one (12 y.o.) developed atrophy of the breast and severe teleangiectasis 18 years later radiotherapy. The other one (42 y.o.) developed severe skin necrosis twenty years later radiotherapy after administration of chemotherapy and received skin graft. A case (52 y.o.) of adenoidcystic carcinoma of the trachea received radiation therapy. The field included the thoracic spinal cord which received 6800 cGy. Two years and 8 months after radiation therapy she developed complete paraplegia and died 5 years later. A truly successful therapeutic outcome requires that the patient be alive, cured and free of significant treatment-related morbidity. As such, it is important to assess quality of life in long-term survivors of cancer treatment. (author)

Introduced in 2008 and subsequently popularized in South Korea, cosmetic eye whitening has been offered as a treatment of chronic conjunctival hyperemia. Patients undergo conjunctivectomy with topical mitomycin C (MMC) 0.02% application to achieve a whitened appearance from bleaching of avascular sclera. Much speculation has arisen from this procedure given the limited available evidence on its efficacy and safety. A literature search was performed to review common complications of cosmetic eye whitening, including chronic conjunctival epithelial defects, scleral thinning, avascular zones in the sclera, dry eye syndrome, and diplopia requiring strabismus surgery. Informing the general public of the risks of this procedure is of great importance for dermatologists and other cosmetic surgeons.

Decorative tattoo is a popular practice that is generally safe when performed in the professional setting but can be associated with a variety of inflammatory, infectious, and neoplastic complications, risks that may be increased with current trends in home tattooing. Modern tattoo inks contain azo dyes and are often of unknown composition and not currently regulated for content or purity. Biopsy of most (if not all) tattoo reactions presenting to the dermatologist is recommended, given recent clusters of nontuberculous mycobacterial infections occurring within tattoo, as well as associations between tattoo reactions and systemic diseases such as sarcoidosis.

Full Text Available Lemierre's syndrome is an anaerobic suppurative thrombophlebitis involving the internal jugular vein secondary to oropharyngeal infection. There is only one previous case report in pregnancy which was complicated by premature delivery of an infant that suffered significant neurological damage. We present an atypical case diagnosed in the second trimester with a live birth at term. By reporting this case, we hope to increase the awareness of obstetricians to the possibility of Lemierre's syndrome when patients present with signs of unabating oropharyngeal infection and pulmonary symptoms.

The purpose of this chapter is to review systematically the toxicity of contemporary chemotherapy and irradiation on normal tissues of growing children. Whenever possible, the separate toxicity of chemotherapy, irradiation, and combination therapy is addressed. However, it is not always possible to quantitate specifically such reactions in the face of multiple drug therapy, which may enhance radiation injury or reactivate prior radiation injury. Prior detailed reviews have provided important sources of information concerning radiation injury for this more general discussion. The information provided will assist both the clinician and the radiologist in the recognition of early and late complications of therapy in pediatric oncology

Osteogenesis imperfecta is a genetic disease characterized by bone frailty. It is generally caused by an abnormal production of collagen, which is the main fibrous protein of the bone. Collagen is also present in the skin, tendons, the sclera of the eye and dentin. The most frequent manifestation of osteogenesis imperfecta is the occurrence of multiple fractures without major trauma. Severity and timing of the attack varies widely: some patients sustain a significant number of fractures during early childhood which may have a serious impact on growth, while others will have some fractures separated by a few years. In all cases, the bone strength improves in adulthood. The bone fractures cause pain and bone deformities sometimes result in a smaller size. Scoliosis is frequent and associated with painful vertebral collapses. We present a case of osteogenesis imperfecta in a 40-year-old adult and we describe the various orthopaedic complications of the disease, stressing the role of bone scintigraphy in the diagnosis and monitoring of these complications.

While most patients undergo orthognathic surgery for aesthetic purposes, aesthetic improvements are most often followed by postoperative functional complications. Therefore, patients must carefully decide whether their purpose of undergoing orthognathic surgery lies on the aesthetic side or the functional side. There is a wide variety of complications associated with orthognathic surgery. There should be a clear distinction between malpractice and complications. Complications can be resolved without any serious problems if the cause is detected early and adequate treatment provided. Oral and maxillofacial surgeons must have a full understanding of the types, causes, and treatment of complications, and should deliver this information to patients who develop these complications.

Currently, there is no generally agreed measure available to quantify a subject's perceived severity of exercise-induced leg pain symptoms. The aim of this study was to develop and validate a questionnaire that measures the severity of symptoms that impact on function and sports ability in patients with exercise-induced leg pain. The exercise-induced leg pain questionnaire for German-speaking patients (EILP-G) was developed in five steps: (1) initial item generation, (2) item reduction, (3) pretesting, (4) expert meeting and (5) validation. The resulting EILP-G was tested for reliability, validity and internal consistency in 20 patients with exercise-induced leg pain, 20 asymptomatic track and field athletes serving as a population at risk and 33 asymptomatic sport students. The patient group scored the EILP-G questionnaire significantly lower than both control groups (each psports ability in patients with exercise-induced leg pain. It can be recommended as a robust tool for measuring the subjectively perceived severity in German-speaking patients with exercise-induced leg pain. Published by the BMJ Publishing Group Limited.

In JET limiter plasmas the density limit is associated with radiated power fractions of 100% and, in plasmas with carbon limiters, it is invariably disruptive. However, in discharges with solid beryllium limiters the limit is identified with the formation of a MARFE and disruptions are less frequent. In addition, the improved conditioning of the vessel arising from the use of beryllium has significantly improved the density limit scaling, so that the maximum density rises with the square root of the input power. In diverted plasmas several confinement regimes exist, making the characterization of the density limit more complex. While the density limit in L-mode plasmas is generally disruptive, the limit in ELMy and ELM-free H-modes generally prompts a return to the L-mode and a disruption is not inevitable. The density limit does rise with the increasing power, but the L-to-H transition complicates the analysis. Nevertheless, at low plasma currents (<2 MA), densities significantly above the Greenwald limit can be achieved, while at higher currents power handling limitations have constrained the range of density which can be achieved.

The number of individuals with prediabetes is expected to grow substantially and estimated to globally affect 482 million people by 2040. Therefore, effective methods for diagnosing prediabetes will be required to reduce the risk of progressing to diabetes and its complications. The current biomarkers, glycated hemoglobin (HbA1c), fructosamine, and glycated albumin have limitations including moderate sensitivity and specificity and are inaccurate in certain clinical conditions. Therefore, identification of additional biomarkers is being explored recognizing that any single biomarker will also likely have inherent limitations. Therefore, combining several biomarkers may more precisely identify those at high risk for developing prediabetes and subsequent progression to diabetes. This review describes recently identified biomarkers and their potential utility for addressing the burgeoning epidemic of dysglycemic disorders. PMID:28860833
Full Text Available Congenital pseudarthrosis of the tibia (CPT is a rare pathology, which is usually associated with neurofibromatosis type I. The natural history of the disease is extremely unfavorable and once a fracture occurs, there is a little or no tendency for the lesion to heal spontaneously. It is challenging to treat effectively this difficult condition and its possible complications. Treatment is mainly surgical and it aims to obtain a long term bone union, to prevent limb length discrepancies, to avoid mechanical axis deviation, soft tissue lesions, nearby joint stiffness, and pathological fracture. The key to get primary union is to excise hamartomatous tissue and pathological periosteum. Age at surgery, status of fibula, associated shortening, and deformities of leg and ankle play significant role in primary union and residual challenges after primary healing. Unfortunately, none of invasive and noninvasive methods have proven their superiority. Surgical options such as intramedullary nailing, vascularized fibula graft, and external fixator, have shown equivocal success rate in achieving primary union although they are often associated with acceptable results. Amputation must be reserved for failed reconstruction, severe limb length discrepancy and gross deformities of leg and ankle. Distinct advantages, complications, and limitation of each primary treatment as well as strategies to deal with potential complications have been described. Each child with CPT must be followed up till skeletal maturity to identify and rectify residual problems after primary healing.

Patients desiring improved neck and jawline contours often are looking for minimally invasive procedures and are not interested in undergoing extensive face-lifting procedures. Realizing the limitations, surgeons may offer their patient such procedures as liposuction and submentoplasty. Even though these procedures are less involved than a facelift, many pitfalls can occur, leading to an unfavorable result and a disappointed patient. Proper patient selection and choosing the correct operation are crucial to avoiding these situations. This article focuses on the common complications of neck liposuction and submentoplasty and reviews the management and avoidance of these complications.

The radiation pneumonitis is a major complication for patients recieving thoracic irradiation. This report describe the radiographic recognition, pathological change and imapired pulmonary functions of radiation pneumonitis. The 57 patients with lung cancer treated with radiation are analyzed on the pneumonitis by chest X-P. Among these, 50 patients (88%) develop radiation pneumonitis. Repeated CT scans give more detailed information than conventional radiograms as to exdative changes. The pathological analysis are made on the 35 patients of which affected lungs are resected after pre-operative irradiation. Three phases are recognized in the evolution of pneumonitis, the ongestive, the degenerative, and the fibrotic. Adding to the morphorogical damage, pulmonary functions also detrieorate both in ventilation and perfusion scans. (author)

Chemoradiotherapy protocols are a recent development in the management of tumours where preservation of organ function is important. It is now recognized that such combined treatment may produce adverse effects below the accepted dose thresholds for either modality. This enhancement of toxicity is generally thought to reflect depletion of stem cells within the tissue concerned. We report four patients who have developed avascular necrosis or fractures of the hip following chemoradiotherapy for carcinoma of the vulva or anus. These complications developed after a radiation dose of 4500 cGy in 20 fractions. The possible role of cytotoxic agents in sensitizing bone to radiation damage is discussed, and a novel mechanism is proposed to account for this phenomenon. (author).
Neurologic disturbances including encephalopathy, seizures, and focal deficits complicate the course 10-30% of patients undergoing organ or stem cell transplantation. While much or this morbidity is multifactorial and often associated with extra-cerebral dysfunction (e.g., graft dysfunction, metabolic derangements), immunosuppressive drugs also contribute significantly. This can either be through direct toxicity (e.g., posterior reversible encephalopathy syndrome from calcineurin inhibitors such as tacrolimus in the acute postoperative period) or by facilitating opportunistic infections in the months after transplantation. Other neurologic syndromes such as akinetic mutism and osmotic demyelination may also occur. While much of this neurologic dysfunction may be reversible if related to metabolic factors or drug toxicity (and the etiology is recognized and reversed), cases of multifocal cerebral infarction, hemorrhage, or infection may have poor outcomes. As transplant patients survive longer, delayed infections (such as progressive multifocal leukoencephalopathy) and post-transplant malignancies are increasingly reported.

Full Text Available Introduction: Complications associated with blood donation significantly lower odds of subsequent donations. The aim of the study is to assess the prevalence of complications related to blood donation, identify the influencing factors, and come up with suggestions for minimizing discomfort to donors and making outdoor voluntary blood donation camps safer. Materials and Methods: This study covered 181 blood donation camps organized by Sankalp India Foundation where 16 blood banks participated from 01-04-2011 to 01-08-2014 in Karnataka. Uniform protocols for donor selection, predonation preparation, counseling, postdonation care, and refreshments were used. The postdonation complications were recorded on a form immediately, after they were observed. Results: We observed 995 (3.2% complications in 30,928 whole blood donations. Of these 884 (2.86% mild, 77 (0.25% moderate, and 5 (0.02% severe complications were observed. Local symptoms (blood outside vessels, pain, and allergy contributed 1.0%, and generalized symptoms (vasovagal reaction contributed 2.2% to all the complications. Conclusion: We observed 322 complications for every 10,000 donations. Since 27 out of every 10000 experience moderate and severe complication, the readiness to manage complications is crucial. Women donors, young donors, and donors with a lower weight are at a significantly greater risk of experiencing complications, highlighting the need for specific guidelines for the management of higher risk donor groups. Complications varied significantly between various blood banks. Predonation hydration was effective in limiting complications with generalized symptoms. We recommend a robust donor hemovigilance program for voluntary blood donation for monitoring complications and enable assessment of effectiveness and implementation of appropriate interventions.

Major postoperative complications are associated with a substantial increase in hospital costs. Trauma patients are known to have a higher rate of complications than the general surgery population. We used the National Surgical Quality Improvement Program (NSQIP) methodology to evaluate hospital costs, duration of stay, and payment associated with complications in trauma patients. Using NSQIP principles, patient data were collected for 512 adult patients admitted to the trauma service for > 24 hours at a Level 1 trauma center (2004-2005). Patients were placed in 1 of 3 groups: no complications (none), >or=1 minor complication (minor, eg, urinary tract infection), or >or=1 major complication (major, eg, pneumonia). Total hospital charges, costs, payment, and duration of stay associated with each complication group were determined from a cost-accounting database. Multiple regression was used to determine the costs of each type of complication after adjusting for differences in age, sex, new injury severity score, Glasgow coma scale score, maximum head abbreviated injury scale, and first emergency department systolic blood pressure. A total of 330 (64%) patients had no complications, 53 (10%) had >or= 1 minor complication, and 129 (25%) had >or= 1 major complication. Median hospital charges increased from $33,833 (none) to $81,936 (minor) and $150,885 (major). The mean contribution to margin per day was similar for the no complication and minor complication groups ($994 vs $1,115, P = .7). Despite higher costs, the patients in the major complication group generated a higher mean contribution to margin per day compared to the no complication group ($2,168, P costs when adjusted for confounding variables was $19,915 for the minor complication group (P costs associated with traumatic injury provides a window for assessing the potential cost reductions associated with improved quality care. To optimize system benefits, payers and providers should develop integrated

Endoscopic management of ureteropelvic junction (UPJ) obstruction has a success rate of 80% to 86%. We have been performing a ureteral cutting balloon procedure under fluoroscopic control (Acucise endopyelotomy) for UPJ obstruction at Loyola University Medical Center since 1991. The overall success rate in 77 patients was 78%. All patients had a preoperative intravenous urogram or a retrograde pyelogram, but none had vascular imaging studies. Acucise endopyelotomy consisted of a posterolateral incision of the UPJ and placement of an endopyelotomy or double-J stent. Foley catheter placement at the end of the procedure demonstrated significant gross hematuria in three patients (4%). All three remained hemodynamically stable but with significant drops in postprocedure hemoglobin levels, which necessitated blood transfusion. Aggressive management included angiographic studies and embolization of lower-pole branching arteries in two patients (3%). One patient stopped bleeding after being given two units of blood. None of the patients required an open exploratory procedure. Although the risk of vascular injury is low with Acucise endopyelotomy, prolonged postoperative gross hematuria does mandate investigation and observation. Angiographic embolization appears to be the therapeutic modality of choice for patients with hemorrhagic complications after an Acucise endopyelotomy.

Neonatal ostomies, either temporary or permanent, are created for numerous reasons. Limited attention has been given to understanding what factors might place infants at risk for surgical wound complications. The purpose of the study is to identify factors associated with risk of significant abdominal wound complications (wound dehiscence and wound infection) following neonatal ostomy creation. This is a retrospective chart review of infants undergoing ostomy between January 2009 and December 2013 at the University of Alberta Hospital. 66 infants were identified of which 18.2% (12/66) had wound complications. Variables associated with wound dehiscence included: findings of bowel necrosis during laparotomy (7/9 wound dehiscence, 18/57 none, p=0.008), perioperative sepsis (3/9 wound dehiscence, 3/57 none, p=0.006), and perioperative blood transfusion (9/9 wound dehiscence, 30/57 none, p=0.007). Wound infection was not predicted by any variables collected. Neonates undergoing creation of an ostomy appear to be at substantial risk for wound complications. As wound complications are significant issues for infants undergoing surgery, emerging strategies should be explored to either avoid ostomy creation or promote wound healing.

The increasing prevalence and severity of obesity in children and adolescents has provided greater emphasis on the wide variety of comorbid conditions and complications that can be experienced as a consequence of obesity. These complications can occur both in the short term and in the long term. Some complications, earlier thought to be long-term issues, which would only occur in adulthood, have now been shown to occur in children and adolescents. These findings have raised concerns about the overall health experience of those who develop obesity early in life and have even raised questions about whether the obesity epidemic might shorten the life span of the current generation of children. In this paper, I will examine current knowledge regarding the different organ systems that may be impacted by childhood obesity.

Full Text Available Colonic complications of severe acute pancreatitis occur rarely. Although there have been several theories on how pancreatic pseudocysts rupture into the colon, the exact pathogenesis remains unknown. We report an unusual case of pseudocysts complicating severe acute pancreatitis presenting with colonic perforation in a 71-year-old man with a history of chronic mesenteric ischemia. Pressure effects from a giant pseudocyst and intravascular volume depletion with acute insult on chronic mesenteric ischemia are highlighted as possible etiologic factors.

Bariatric surgery is considered to be the most effective treatment of morbid obesity and improvement of obesity-related comorbidities, such as type II diabetes. However, both peripheral and central neurological complications can occur after bariatric surgery. Such complications tend to occur more frequently after bypass surgery than after sleeve gastrectomy (SG). The objective of this study was to identify the patients that presented post-operative neurological complications after undergoing SG and describe the incidence, presentation, and management of these complications. This was a retrospective study of 592 cases of SG performed between 2009 and 2014 with a special focus on patients who presented neurological complications. Of the 592 SG cases, only seven (1.18 %) patients presented neurological complications. All patients had uneventful post-operative course, but all reported feeding difficulties, accompanied by severe dysphagia, and rapid weight loss, with a mean weight loss of 35 kg (30-40 kg) 3 months after SG. All patients were readmitted owing to neurological symptoms that included paresthesia, abolition of deep tendon reflexes of the lower limbs, muscle pain, and motor and sensitive deficits in some cases. There were two cases of Wernicke's encephalopathy. All patients were treated for neuropathy secondary to vitamin B1 deficiency and had a significant improvement and/or resolution of their symptoms. Neurological complications after SG are rare and are often preceded by gastrointestinal symptoms, rapid weight loss, and lack of post-operative vitamin supplementation. Re-hospitalization and multidisciplinary team management are crucial to establish the diagnosis and initiate treatment.

In spite of many advances in medicine, anesthetic technique and surgical managements, pulmonary problems are the most frequent postoperative complications, particularly after abdominal surgery. As postoperative pulmonary complications, atelectasis, pleural effusion, pneumonia, chronic bronchitis and lung abscess can be occurred. This study include evaluation of chest films of 2006 patients (927 male, 1079 female), who had been operated abdominal surgery from Jan. 1979 to June, 1980 in the Hanyang university hospital. The results were as follows: 1. 70 cases out of total 2006 cases (3.5%) developed postoperative chest complications, 51 cases (5.5%) in male, 19 cases (1.8%) in female. 2. The complication rate was increased according to the increase of age. The incidence of the postoperative complications over 40 years of age was higher than the overall average complications rate. 3. The most common postoperative pulmonary complication was pleural effusion, next pneumonia, atelectasis and pulmonary edema respectively. 4. The complication rate of the group of upper abdominal surgery is much higher than the group of lower abdominal surgery. 5. Complication rate was increased according to increase of the duration of operation. 6. There were significant correlations between the operation site and side of the complicated hemithorax

Meckel's diverticulum is the most common congenital abnormality of the small bowel. The majority of patients with this anomaly will remain asymptomatic; however, several complications may occur, including obstruction, intussusception, perforation, diverticulitis, and gastrointestinal haemorrhage. These complications may produce a variety of different clinical features and radiological appearances. The purpose of this article is to review the potential imaging manifestations of Meckel's diverticulum and its complications and discuss the advantages and disadvantages of the imaging techniques available

Inherent to anorexia nervosa and bulimia nervosa are a plethora of medical complications which correlate with the severity of weight loss or the frequency and mode of purging. Yet, the encouraging fact is that most of these medical complications are treatable and reversible with definitive care and cessation of the eating-disordered behaviours. Herein, these treatments are described for both the medical complications of anorexia nervosa and those which are a result of bulimia nervosa.

Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections (alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum -a major contributor to fracture healing- in the femoral neck. In extracapsular fractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients.

Severe Ventral Erosion of Penis Caused by Indwelling Urethral Catheter and Inflation of Foley Balloon in Urethra—Need to Create List of “Never Events in Spinal Cord Injury” in order to Prevent These Complications from Happening in Paraplegic and Tetraplegic Patients
Full Text Available Never Events are serious, largely preventable patient safety incidents that should not occur if the available preventative measures have been implemented. We propose that a list of “Never Events” is created for spinal cord injury patients in order to improve the quality of care. To begin with, following two preventable complications related to management of neuropathic bladder may be included in this list of “Never Events.” (i Severe ventral erosion of glans penis and penile shaft caused by indwelling urethral catheter; (ii incorrect placement of a Foley catheter leading to inflation of Foley balloon in urethra. If a Never Event occurs, health professionals should report the incident through hospital risk management system to National Patient Safety Agency's Reporting and Learning System, communicate with the patient, family, and their carer as soon as possible about the incident, undertake a comprehensive root cause analysis of what went wrong, how, and why, and implement the changes that have been identified and agreed following the root cause analysis.

Twenty five per cent of thermal injuries are associated with secondary respiratory events linked to several mechanisms. In the acute phase of the accident oedema of the airways, the fume inhalation syndrome and ARDS are the most common causes responsible for death in 60% of cases. Late respiratory complications are little known and neglected. They comprise obstructive ventilatory defects due to the inhalation syndrome and restrictive defects secondary to ARDS or to dermal injury. We report the case of a female patient, extensively burnt 2 years previously, admitted to hospital with severe acute respiratory failure complicating COPD. The presence of both restrictive and obstructive defects led to the suggestion of alternative underlying mechanisms such as the pulmonary consequences of ARDS and extensive dermal scars. The latter were responsible for an armour like thickening of the skin of the thorax compatible with the restrictive defect. These functional abnormalities and the potential severity of acute respiratory failure are indications for regular pulmonary follow-up of patients with severe circumferential scarring of the thorax who are at high risk for respiratory complications.

The prevalence of anemia varies from country to country and there is not a trustworthy record. To determine the frequency of anemia in obstetric patients and the association among healthy pregnancy and aggregate complications. Was carried out as transversal, observational and comparative study. Obstetrical patients entered and responded in the period of a year, were formed a group with normal pregnancy and another with complicated pregnancy, with a total sample of 194 patients. In the statistical analysis was employed Student t test for independent groups, with value if p anemia was found in 22.4%. Hematological stage from group with normal pregnancy was mild anemia in 16.9% and anemia moderated in 4.1% of the cases. The anemia degrees in the group with associated illness and pregnancy were mild anemia in 19.2% and moderated anemia in 4.2%. Not any case was found with severe anemia. The statistical analysis showed difference significant among both groups p preeclampsia severe (22.6%), type 2 diabetes (13.9%), gestational diabetes (12.2%) and the remainder with other complications that include to the hypertiroidism, rheumatoid arthritis, lupus, asthma and vein deep thrombosis. Frequency of anemia in this study was greater upon informing in the international literature. The obstetrical complication more frequently relates to diverse anemia degrees were the hypertensive stage during pregnancy. The anemia is presented with greater frequency in pregnancy patients with others associated illness.

Secondary bacterial pneumonia after viral respiratory infection remains a significant source of morbidity and mortality. Susceptibility is mediated by a variety of viral and bacterial factors, and complex interactions with the host immune system. Prevention and treatment strategies are limited to influenza vaccination and antibiotics/antivirals respectively. Novel approaches to identifying the individuals with influenza who are at increased risk for secondary bacterial pneumonias are urgently needed. Given the threat of further pandemics and the heightened prevalence of these viruses, more research into the immunologic mechanisms of this disease is warranted with the hope of discovering new potential therapies.

Background: An increasing number of patients survive cancer after having received radiation therapy. Therefore, the occurrence of late normal tissue complications among long-term survivors is of particular concern. Methods: Sixty-three patients treated by radical surgery and irradiation for rectal carcinoma were subjected to an unconventional sandwich therapy. Preoperative irradiation was given in four fractions of 5 Gy each applied within 2 or 3 days; postoperative irradiation consisted mostly of 15x2 Gy (range, 20-40 Gy). A considerable proportion of these patients developed severe late complications (Radiother Oncol 53 (1999) 177). The data allowed a detailed analysis of complication kinetics, leading to a new model which was tested using data from the literature. Results: Data on late complications were obtained for eight different organs with a follow-up of up to 10 years. For the various organs, the percentage of patients being free from late complications, plotted as a function of time after start of radiation therapy, was adequately described by exponential regression. From the fit, the parameter p a was obtained, which is the percentage of patients at risk in a given year of developing a complication in a given organ during that year. The rate p a remained about constant with time. Following sandwich therapy, the annual incidence of complications in the bladder, ileum, lymphatic and soft tissue, and ureters was about the same (p a =10-14%/year), whereas complications in bone or dermis occurred at lower rates (4.7 or 7.5%/year, respectively). Discussion: Numerous data sets collected from published reports were analyzed in the same way. Many of the data sets studied were from patients in a series where there was a high incidence of late effects. Three types of kinetics for the occurrence of late effects after radiotherapy were identified: Type 1, purely exponential kinetics; Type 2, exponential kinetics, the slope of which decreased exponentially with time
Radiation and radioactivity were discovered more than 100 years ago. Since then, radiation has become important in cancer treatment. Approximately one million people will develop invasive cancer each year. Of these, 40% will receive curative benefit from surgery, radiation, chemotherapy, or a combination modality. Normal body tissues vary in their response to radiation. As with tumors, normal tissues in which cells are quickly dividing may be affected. This causes some of the side effects of radiation treatment. Since radiation is a local treatment, side effects depend on the area of the body being treated. The early effects of radiation may be seen a few days or weeks after treatments have started and may go on for several weeks after treatments have ended. Other effects may not show up until months, or even years, later. As radiotherapy is a viable treatment modality for head and neck cancer, however a wide range of potentially debilitating dental complications may accompany this treatment. The orofacial tissues of dental significance that may be affected by head and neck radiotherapy are the salivary glands, mucous membranes, taste buds, bone and teeth. (author)

To determine the effect of steroid treatment on visual outcome and ocular complications in patients with presumed ocular tuberculosis. Retrospective review of patients with presumptive ocular tuberculosis. The clinical diagnosis was made based on ocular findings, positive purified protein derivative (PPD) testing of more than 15 mm induration, exclusion of other causes of uveitis and positive ocular response to anti-tuberculous therapy (ATT) within 4 weeks. Group 1 included patients who had received oral prednisone or subtenon injection of triamcinolone acetonide prior to ATT. Group 2 included patients who did not receive corticosteroid therapy prior to administration of ATT. Among 500 consecutive new cases of uveitis encountered in 1997-2007 there were 49 (10%) patients with presumed ocular tuberculosis. These comprised 28 (57%) male and 21 (43%) female patients with a mean age of 45 years (range 12-76 years). Four (20%) patients in group 1 had initial visual acuity of 20/40 or better, in comparison to eight (28%) patients in group 2. At 1-year follow-up, six (30%) patients in group 1 had a visual acuity of 20/40 or better compared with 20 (69%) patients in group 2 (p = 0.007). Of 20 eyes (26%) in group 1 that had visual acuity of < 20/50 at 1-year follow up, 14 (70%) eyes developed severe chorioretinal lesion (p = 0.019). Early administration of corticosteroids without anti-tuberculous therapy in presumed ocular tuberculosis may lead to poor visual outcome compared with patients who did not receive corticosteroids prior to presentation. Furthermore, the severity of chorioretinitis lesion in the group of patients given corticosteroid prior to ATT may account for the poor visual outcome. © 2009 The Authors.

Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating surgery. Pledgets of gelatin sponge as torpedoes are commonly used for safe TAE, and coils, glue, and microspheres have been primarily used in specific situations such as arterial rupture, pseudoaneurysm, and arteriovenous fistula. TAE is a minimally invasive procedure with a low rate of complications, which preserves future fertility. Knowledge of causes of PPH, potential risks, and limitations of TAE is essential for a timely decision, optimizing TAE, preventing irreversible complications, avoiding hysterectomy, and ultimately preserving fertility.

Transcatheter aortic valve replacement (TAVR) is now an accepted pathway for aortic valve replacement for patients who are at prohibitive, severe and intermediate risk for traditional aortic valve surgery. However, with this rising uptrend and adaptation of this new technology, vascular complications and their management remain an Achilles heel for percutaneous aortic valve replacement. The vascular complications are an independent predictor of mortality for patients undergoing TAVR. Early recognition of these complications and appropriate management is paramount. In this article, we review the most commonly encountered vascular complications associated with currently approved TAVR devices and their optimal percutaneous management techniques.

The complication rate following radiofrequency catheter ablation for atrial fibrillation is low (<5%). Complications include pericardial effusion, cardiac tamponade, pulmonary vein stenosis, oesophageal ulceration or perforation, atrio-oesophageal fistula formation, stroke/transient ischaemic attack, phrenic nerve injury, haematoma at the puncture site, and femoral arteriovenous fistula. Among available imaging tools, computed tomography (CT) can be very useful in diagnosing complications of the procedure, particularly in the subacute and delayed stages after ablation. This review illustrates CT imaging of several of the common and uncommon complications of radiofrequency catheter ablation

Pulmonary nocardiosis is a severe and uncommon opportunistic infection caused by Nocardia species. We present a patient with cryptogenic organizing pneumonia who was receiving long-term immunosuppressive therapy, whose treatment course was complicated by cutaneous and pulmonary nocardiosis. Tissue cultures confirmed Nocardia brasiliensis . Nocardiosis should be a diagnostic consideration for patients treated with long-term immunosuppression who have worsening pulmonary symptoms and relapsing pustular skin lesions.

Objectives: To investigate the prevalence of ocular injuries in a large population of boxers over a period of 16 years, in particular, the most severe lesions that may be vision threatening. Methods: Clinical records of the medical archive of the Italian Boxing Federation were analysed. A total of 1032 boxers were examined from February 1982 to October 1998. A complete ophthalmological history was available for 956, who formed the study population (a total of 10 697 examinations). The following data were collected: age when started boxing; duration of competitive boxing career (from the date of the first bout); weight category; a thorough ocular history. The following investigations were carried out: measurement of visual acuity and visual fields, anterior segment inspection, applanation tonometry, gonioscopy, and examination of ocular fundus. Eighty age matched healthy subjects, who had never boxed, formed the control group. Results: Of the 956 boxers examined, 428 were amateur (44.8%) and 528 professional (55.2%). The median age at first examination was 23.1 (4.3) years (range 15–36). The prevalence of conjunctival, corneal, lenticular, vitreal, ocular papilla, and retinal alterations in the study population was 40.9% compared with 3.1% in the control group (p⩽0.0001). The prevalence of serious ocular findings (angle, lens, macula, and peripheral retina alterations) was 5.6% in boxers and 3.1% in controls (NS). Conclusions: Boxing does not result in a higher prevalence of severe ocular lesions than in the general population. However, the prevalence of milder lesions (in particular with regard to the conjunctiva and cornea) is noteworthy, justifying the need for adequate ophthalmological surveillance. PMID:15665199
Full Text Available Pulmonary complications are a major cause of morbidity and mortality in neurosurgical patients. The common pulmonary complications in neurosurgical patients include pneumonia, postoperative atelectasis, respiratory failure, pulmonary embolism, and neurogenic pulmonary edema. Postoperative lung expansion strategies have been shown to be useful in prevention of the postoperative complications in surgical patients. Low tidal volume ventilation should be used in patients who develop acute respiratory distress syndrome. An antibiotic use policy should be put in practice depending on the local patterns of antimicrobial resistance in the hospital. Thromboprophylactic strategies should be used in nonambulatory patients. Meticulous attention should be paid to infection control with a special emphasis on hand-washing practices. Prevention and timely management of these complications can help to decrease the morbidity and mortality associated with pulmonary complications.

Full Text Available Complicated malaria remains an important public health problem, particularly in endemic settings where access to health services is limited and consequently malaria fatal outcomes occur. Few publications describing the clinical course and outcomes of complicated malaria in Latin America are found in the literature. This prospective study approached the clinical and laboratory characteristics of hospitalized patients with complicated malaria in different endemic areas of the Colombian Pacific Coast with the aim to provide epidemiological knowledge and guide to further reducing malaria severity and mortality.A prospective, descriptive hospital-based study was conducted in 323 complicated malaria patients (median age 20 years enrolled in Quibdó, Tumaco and Cali between 2014 and 2016. Clinical evaluation was performed and laboratory parameters were assessed during hospitalization. Plasmodium falciparum was the most common parasite species (70%, followed by P. vivax (28%, and mixed malaria (Pf/Pv; 1.9%. Overall, predominant laboratory complications were severe thrombocytopenia (43%, hepatic dysfunction (40%, and severe anaemia (34%. Severe thrombocytopenia was more common in adults (52% regardless of parasite species. Severe anaemia was the most frequent complication in children ≤10 years (72% and was most commonly related to P. vivax infection (p < 0.001; whereas liver dysfunction was more frequent in older patients (54% with P. falciparum (p < 0.001. Two deaths due to P. vivax and P. falciparum each were registered. Treatment provision before recruitment hindered qPCR confirmation of parasite species in some cases.The study identified a high prevalence of complicated malaria in the Pacific Coast, together with more frequent severe anaemia in children infected by P. vivax and hepatic dysfunction in adults with P. falciparum. Results indicated the need for earlier diagnosis and treatment to prevent complications development as well as more

We report a case of severe lichenoid drug eruption with multiple possible causative agents. A hepatitis C-positive male presented with a short history of painful erosions of the vermilion, lichenoid lesions on the buccal mucosa and glans penis, and erosions and lichenification of the scrotum. In addition, he had a pruritic polymorphic eruption over the scalp, trunk and limbs, comprising psoriasiform and eczematous lesions. He had received combination therapy of pegylated interferon-alpha-2a and ribavirin, along with granulocyte colony-stimulating factor for interferon-induced leucopenia, and propranolol for portal hypertension. The former three agents were ceased 3 weeks prior to presentation, but he remained on propranolol at the initial dermatology consultation. The polymorphous clinical picture was consistent with lichenoid drug eruption, which was confirmed on histology. The papulosquamous eruption responded quickly to 2 weeks of oral prednisone 25 mg daily, which was tapered to 1 mg over 3 months and then ceased. The mucosal lesions were slow to improve and required the addition of tacrolimus 0.03% solution t.d.s. for complete resolution.

This study evaluated early bowel complications in cervix cancer patients, following external radiotherapy (ERT) and high dose rate intracavitary radiation (HDR ICR). Factors affecting the risk of developing early bowel complications and its incidence are analyzed and discussed. The study is the retrospective review of 66 patients who received radiotherapy at Chungbuk National University Hospital from April 1994 to December 1998. The patients underwent 41.4 or 50.4 Gy ERT according to FIGO stage and tumor size, then A point dose was boosted to 71.4 or 74.4 Gy using a remotely controlled after loading Buchler HDR ICR. The EORTC/RTOG morbidity criteria were used to grade early bowel complications, which are valid from day 1, the commencement of therapy, through day 90. The actuarial incidence, severity of complications were investigated and clinical pretreatment factors relevant to complications were found through univariate (Wilcoxon) and multivariate (Cox proportional hazard model) analysis. Of the 66 patients, 30 patients (46%) developed early bowel complications; 25 patients (38%) with grade 1 or 2, 4 patients (6%) with grade 3 and 1 patient (2%) with grade 4. The complications usually began to occur 3 weeks after the commencement of radiotherapy. The actuarial incidence of early bowel complications was 41% at 10 weeks. The early bowel complications were associated significantly with an old age and a history of previous abdomino-pelvic surgery. All three patients who had a protracted overall treatment time (about 2 weeks) due to severe bowel complication, suffered from pelvic recurrences. Forty six percent of patients experienced early bowel complications, most of which were grade 1 or 2 and relieved spontaneously or by medication. The patients with an old age or a previous surgery have a high probability of early complications and they may be less compliant with planned radiotherapy. So more careful precaution is necessary for these patients

Mandible angle fractures can be repaired in a variety of ways, with no consensus on the outcomes of complications and reoperation rates. To analyze patient, injury, and surgical factors, including approach to the angle and plating technique, associated with postoperative complications, as well as the rate of reoperation with regard to mandible angle fractures. Retrospective cohort study analyzing the surgical outcomes of patients with mandible angle fractures between January 1, 2000, and December 31, 2015, who underwent open reduction and internal fixation. Patients were eligible if they were aged 18 years or older, had 3 or less mandible fractures with 1 involving the mandibular angle, and had adequate follow-up data. Patients with comminuted angle fractures, bilateral angle fractures, and multiple surgical approaches were excluded. A total of 135 patients were included in the study. All procedures were conducted at a single, large academic hospital located in an urban setting. Major complications and reoperation rates. Major complications included in this study were nonunion, malunion, severe malocclusion, severe infection, and exposed hardware. Of 135 patients 113 (83.7%) were men; median age was 29 years (range, 18-82 years). Eighty-seven patients (64.4%) underwent the transcervical approach and 48 patients (35.6%) received the transoral approach. Fifteen (17.2%) patients in the transcervical group and 9 (18.8%) patients in the transoral group experienced major complications (difference, 1%; 95% CI, -8% to 10%). Thirteen (14.9%) patients in the transcervical group and 8 (16.7%) patients in the transoral group underwent reoperations (difference, 2%; 95% CI, -13% to 17%). Active smoking had a significant effect on the rate of major complications (odds ratio, 4.04; 95% CI, 1.07 to 15.34; P = .04). During repair of noncomminuted mandibular angle fractures, both of the commonly used approaches-transcervical and transoral-can be used during treatment with equal

Controversy exists over association of blood transfusions with complications. The purpose was to assess effects of limited transfusions on complication rates and hospital course. Level 1 trauma center. Three hundred seventy-one consecutive patients with Injury Severity Score ≥16 underwent fixation of fractures of spine (n = 111), pelvis (n = 72), acetabulum (n = 57), and/or femur (n = 179). Those receiving >3 units of packed red blood cell were excluded. Fracture type, associated injuries, treatment details, ventilation time, complications, and hospital stay were prospectively recorded. Ninety-eight patients with 107 fractures received limited transfusion, and 119 patients with 123 fractures were not transfused. The groups did not differ in age, fracture types, time to fixation, or associated injuries. Lowest hematocrit was lower in the transfused group (22.8 vs. 30.0, P < 0.0001). Surgical duration (3:23 vs. 2:28) and estimated blood loss (462 vs. 211 mL) were higher in transfused patients (all P < 0.003). Pulmonary complications occurred in 12% of transfused and 4% of nontransfused, (P = 0.10). Mean days of mechanical ventilation (2.51 vs. 0.45), intensive care unit days (4.5 vs. 1.5) and total hospital stay (8.8 vs. 5.7) were higher in transfused patients (all P ≤ 0.006). After multivariate analysis, limited transfusion was associated with increased hospital and intensive care unit stays and mechanical ventilation time, but not with complications. Patients receiving ≤3 units of packed red blood cell had lower hematocrit and greater surgical burden, but no difference in complications versus the nontransfused group. Limited blood transfusions are likely safe, excepting a possible association with longer mechanical ventilation times and hospital stays. Therapeutic level III.

From 1966 to 1973, 215 patients with cervical cancer were treated at the Department of Obstetrics and Gynecology, School of Medicine, Iwate Medical University. The patients were divided into two groups. In the first group, 123 patients were treated by external radiation with Tele- 60 Co plus radium insertions (1966-1970). In the second group, 83 patients were treated with linear accelerator plus cesium insertions (1970-1973). The results on both of 5-year survival rate and appearance of radiation injuries were compared with two groups. There was no significant difference in the cure rate between those of groups. The incidence of pigmentation, edema and diarrhea (early complications) was higher and the diarrhea continued significantly longer in the second group. The incidence of rectal ulcer and rectostenosis (later complications) was significantly higher than former group. A study was made to lean the reason for the significant higher occurrence of rectal ulcer and rectostenosis. As a result, it was determined that later complication was more emphasized especially by ret dose given intracavitary radiation. In addition, it is thought that the dose rate, the dose volume and natural history such as the patients' age are also related to the severity of the complication. (J.P.N.)

Full Text Available Liver complications in haemoglobinopathies (thalassaemia and sickle cell disease are due to several factors, dominated (beside chronic viral infections, not considered here by chronic iron overload, biliary obstruction and venous thrombosis. Whereas the latter two factors can cause acute hepatic syndromes, all three mechanisms - when becoming chronic- can produce fibrosis and cirrhosis and even, in thalassaemia, hepatocellular carcinoma. These chronic hepatic complications are an indirect consequence of the significant improvement in life expectancy due to the overall amelioration of disease management. The diagnostic approach has benefited from non invasive (biochemical and imaging approaches which have considerably reduced the indication of liver biopsy. The therapeutic management involves relatively efficient curative medical, endoscopic or surgical methods, but should rest primarily on preventive measures focused on the haematological causative factors but also on hepatic co-morbidities. This chapter will focus on hepatic complications in thalassaemia and sickle cell disease (SCD, without considering the complications related to virus B or C infections which will be described in another chapter.

Glaucoma drainage devices (GDDs) have been generally accepted as a treatment of refractory glaucoma. GDDs have their own unique set of complications that are important to evaluate to prevent them. Tube shunts are typically used in eyes with refractory glaucoma. There is increased interest in studying the efficacy of GDDs. Most of the attention has been focused on comparing trabeculectomy with the Baerveldt implant (Advanced Medical Optics, Inc., Santa Anna, California, USA). The other leading implant is the Ahmed Glaucoma Valve. There are several retrospective studies comparing these two devices and a prospective study is ongoing. There is great interest in the complication rate of tube shunts and these have been published both retrospectively and prospectively. Complications such as hypotony, diplopia, strabismus, proptosis, tube erosion, failure, corneal decompensation, endophthalmitis, and visual loss are all important and some have recently been reviewed in the literature. Moreover, the use of glaucoma drainage implants in the pediatric population has been evaluated. Glaucoma drainage implants have been a powerful tool in our surgical fight to prevent blindness; however, they are not without complications or controversy.

Some earlier studies have indicated that patients with inflammatory bowel disease, especially those with long-standing and extensive ulcerative colitis, have an increased risk of colorectal cancer. Moreover, others in tertiary care centres have suggested that patients with Crohn's disease also have a higher risk of colorectal cancer. Canadian data on colorectal cancer in Crohn's disease appear to be limited. For this investigation, a single clinician database of 877 patients with Crohn's disease was used. Altogether, there were six patients with colorectal cancer (ie, overall rate of 0.7%). All of these patients were men with an initial diagnosis of Crohn's disease established at a mean age of approximately 28 years, with either ileocolonic disease or colonic disease alone, but not with ileal disease alone. Although there was a predominance of women in the overall study population (ie, 56.1%), no women developed colorectal cancer. The clinical behaviour of Crohn's disease was classified as nonstricturing in all six patients with colorectal cancer, but in two patients, Crohn's disease was complicated by a perirectal abscess or a fistula. All cancers were located in the rectum and were diagnosed 30 years, 22 years, seven years, 18 years, 20 years and 40 years after Crohn's disease was initially diagnosed. In three patients, the cancer was detected in a residual rectal stump after a partial colon resection at least 10 years earlier. In five patients, localized extension of disease through the serosa, nodal or distant metastases (ie, liver, lung) was found at the time of cancer diagnosis; two patients have since died. The present study confirms that Crohn's disease involving the colon may be a possible risk factor for the development of colorectal cancer, at least in younger men, but, in this study, not in women. However, part of this increased risk in men may have been related to the presence of a rectal stump, rather than to Crohn's disease per se.

Stoma complications occur in 21-75% of patients, and 30% of them require redo surgery within 10 years after previous surgical treatment. Medical treatment is successful in most cases with no need for surgery. However, severe stoma complications are the real challenge for medical team and require an individual approach to each patient. The aim of the study was to report stoma patients with severe complications of both ileo- and/or colostomy and present different options of medical treatment. Between March 2005 and April 2007 we treated 8 patients with severe stoma complications at the Department of General and Colorectal Surgery, Medical University of Łódź. There were 4 patients with colostomy, 3 patients with ileostomy and one patient with both ileo- and colostomy. The mean age of patients was 56,7 years (range 30-68 years). In all patients we achieved either complete stoma-related wound healing or we observed substantial progress of wound healing with medical treatment. No patient required surgery for stoma complications. Stoma complications still occur in spite of adherence to rules of stoma care and surgical technique. Most of them can be treated conservatively. Much emphasis is put on close team work comprising doctors and nurses in the treatment of severe stoma complications.

A percutaneous endoscopic gastronomy tube can be used to deliver nutrition, hydration and medicines directly into the patient's stomach. Patients will require a tube if they are unable to swallow safely, putting them at risk of aspiration of food, drink and medicines into their lungs. It is vital that nurses are aware of the complications that may arise when caring for a patient with a PEG tube. It is equally important that nurses know how to deal with these complications or from where tc seek advice. This article provides a quick troubleshooting guide to help nurses deal with complications that can arise with PEG feeding.

The life expectancy of patients with cystic fibrosis (CF) has steadily increased over recent decades with a corresponding increase in the frequency of complications of the disease. Radiologists are increasingly involved with managing and identifying the pulmonary complications of CF. This article reviews the common manifestations of CF lung disease as well as updating radiologists with a number of less well-known complications of the condition. Early and accurate detection of the pulmonary effects of CF are increasingly important to prevent irreversible lung damage and give patients the greatest possibility of benefiting from the new therapies becoming available, which correct the underlying defect causing CF

Diabetes mellitus （DM） is a important health problemthat induces ernestful complications and it causessignificant morbidity owing to specific microvascularcomplications such as, retinopathy, nephropathy andneuropathy, and macrovascular complications such as,ischaemic heart disease, and peripheral vasculopathy.It can affect children, young people and adults and isbecoming more common. Ocular complications associatedwith DM are progressive and rapidly becoming theworld＇s most significant cause of morbidity and arepreventable with early detection and timely treatment.This review provides an overview of five main ocularcomplications associated with DM, diabetic retinopathyand papillopathy, cataract, glaucoma, and ocular surfacediseases.
Tattooing is a skin trauma and involves a special vulnus punctatum (with inserted tattoo ink, a vulnus venenatum), which should heal with no infection and no local complication. Local treatment in the healing phase ideally builds on the 'moist wound' principle using plastic film, hydrocolloids, silver dressing, and compression. Bacterial infections during healing are treated with oral antibiotics, and a list of first-line antibiotics is proposed. Notice is given to severe infections with affected general condition, and it is emphasized that intravenous antibiotic treatment must be instituted as early as possible to prevent septic shock and death. Hydrophilic antibiotics shall be given in high load and maintenance dose due to increased renal clearance of such antibiotics. Chronic allergic reactions of red tattoos respond little to local corticoids and are best treated with dermatome shaving. Laser removal is contraindicated due to the risk of photochemical activation of the allergy with anaphylaxis or worsening. Chronic reactions in black tattoos can be treated with local corticoids, dermatome shaving, and lasers as well. Systemic corticoid is used in allergic reactions in red tattoos and in cross-allergic reactions of other red tattoos as well as in black tattoo reactions associated with sarcoidosis and with cutaneous 'rush phenomenon' affecting any black tattoo. Systemic corticoid is also indicated in generalized eczema due to nickel allergy or another allergy challenged through tattooing or introduced by tattooing as a primary sensitization. The use of intralesional corticoid, antihistamines, and immunosuppressive medicines is discussed. A warning against the use of lactic acid and other caustic chemicals for tattoo removal is given, since such chemicals and commercial products cannot be dosed properly and very often result in disfiguring scarring. © 2017 S.

Full Text Available Patients with complications of diabetes such as retinopathy, nephropathy, and cardiovascular complications have increased hospital stay with greater economic burden. Prevention of complications should be started before the onset of type 1 diabetes mellitus (T1DM by working on risk factors and thereafter by intervention upon confirmatory diagnosis which can prevent further damage to β-cells. The actual risk of getting microvascular complications like microalbuminuria and retinopathy progression starts at glycated hemoglobin (HbA1c level of 7%. As per the American Diabetes Association, a new pediatric glycemic control target of HbA1c 20 years as compared to patients <10 years of age. Screening of these complications should be done regularly, and appropriate preventive strategies should be followed. Angiotensin converting enzyme inhibitors and angiotensin II receptor blocker reduce progression from microalbuminuria to macroalbuminuria and increase the regression rate to normoalbuminuria. Diabetic microvascular complications can be controlled with tight glycemic therapy, dyslipidemia management and blood pressure control along with renal function monitoring, lifestyle changes, including smoking cessation and low-protein diet. An integrated and personalized care would reduce the risk of development of microvascular complications in T1DM patients. The child with diabetes who receives limited care is more likely to develop long-term complications at an earlier age. Screening for subclinical complications and early interventions with intensive therapy is the need of the hour.

To assess retinal complications and to identify risk factors for retinal complications following aqueous shunt procedures. Records of 38 consecutive aqueous shunt procedures that were performed on 36 patients at the Eye Institute of the Medical College of Wisconsin, Milwaukee, from June 1993 to March 1995 (minimum follow-up, 6 months) were reviewed. The mean +/- SD follow-up was 11.4 +/- 5.2 months (median, 10.5 months). Twelve patients (32%) had the following retinal complications: 4 serous choroidal effusions (10%) that required drainage, 3 suprachoroidal hemorrhages (8%), 2 vitreous hemorrhages (5%), 1 rhegmatogenous retinal detachment (3%), 1 endophthalmitis (3%), and 1 scleral buckling extrusion (3%). Surgical procedures for retinal complications were required in 8 (67%) of these 12 patients. Visual acuity decreased 2 lines or more in 9 (75%) of these 12 patients. The median onset of a postoperative retinal complication was 12.5 days, with 10 patients (83%) experiencing complications within 35 days. Serous choroidal effusions developed in 10 other patients (26%), and these effusions resolved spontaneously. Visual acuity decreased 2 lines or more in 2 (20%) of these additional 10 patients. Patients who experienced serious retinal complications were significantly older, had a higher rate of hypertension, and postoperative ocular hypotony. Serious retinal complications were distributed evenly among patients with Krupin valves with discs and Molteno and Baerveldt devices. Experience with the Ahmed glaucoma valve implant was limited. Aqueous shunt procedures may be associated with significant retinal complications and subsequent visual loss.

A severe, ulcerative cystitis that resulted in macroscopic hematuria occurred in 8 of 20 healthy dogs undergoing a series of diagnostic tests. Four of the remaining 12 dogs had mild bladder lesions consisting of submucosal edema and hemorrhage. Nine of the 20 dogs developed urinary tract infection after the procedures. These complications seemed associated with the radiographic technique of retrograde urethrography performed when the urinary bladder was distended. To test this hypothesis, retrograde urethrography was performed on 5 additional dogs. With the bladder undistended, no complications occurred. However, distention of these same dogs' bladders for 1 minute or less with sterile lactated Ringer's solution administered through a Foley catheter in the penile urethra resulted in a macroscopic hematuria in all 5 dogs which persisted for 24 hours. A microscopic hematuria continued for 5 days. One dog developed a bacterial urinary tract infection. A severe fibrinopurulent cystitis was present at necropsy of 2 dogs 2 days after distention. The morphologic changes in the bladder gradually diminished over 7 days, but mild submucosal edema and hemorrhage were still present when 2 dogs were necropsied, 7 days after distention. These studies indicated that retrograde urethrography in dogs may be complicated by hemorrhagic cystitis and urinary tract infection if performed with urinary bladder distention.

Discussion: Re-expansion pulmonary oedema is a recognised complication of large pleural effusion drainage. The mechanism remains unclear, although reduced left ventricular function, in this case from a possible pericardial effusion, may be a precipitant. To prevent this phenomenon the British Thoracic Society recommends draining a maximum of 1.5 litres of fluid. This case was further complicated by a pneumothorax; again a recognised complication, especially if there is underlying poor compliance of the lung parenchyma. Re-expansion pulmonary oedema has an incidence of <1% and pneumothorax <5%. Their occurrence has not previously been reported simultaneously. Large pleural effusions are commonly encountered in clinical practice in South Africa. The existence of multiple co-morbidities including tuberculosis, HIV and impaired cardiac function may complicate their management. This case highlights the need for close monitoring and controlled drainage of pleural effusions in emergency practice.

Some rare, but serious, complications during leg and pelvic phlebography are described. One fatal pulmonary embolus and six cases of necrosis of the dorsum of the foot due to phlebography were encountered. The causes, pathogenetic factors and other possible complications are discussed. Extravasation of contrast due to puncture on the lateral side of the foot, or near the ankle joint, leads to the formation of a contrast bleb which may proceed to tissue necrosis.

The AIM of this retrospective study was to evaluate the emergency surgical treatment of life-threatening complications of colonic diverticula. In the last 11 years, 22 of 101 patients with colonic diverticula (22.1%) underwent urgent surgery for acute complications: perforated gangrenous diverticulitis with generalized peritonitis (n=8) or pericolic abscess (n=8), acute bowel obstruction (n=4) and severe diverticular bleeding (n=2). In all patients with diffuse peritonitis or acute obstruction the indication for surgery was decided on clinical basis and the complicated diverticula were recognized only intra-operatively. Emergency surgical strategy differed according to the type of complication and the biologic condition of the patient: segmental colectomy and primary anastomosis for diverticular perforation (n=4), colonic stenosis (n=3) or diverticular bleeding (n=2); Hartmann resection with late reconnecting anastomosis in patients with diverticular perforation (n=5) or colonic obstruction (n=1); diverticulectomy with peritoneal drainage (n=2) and colostomy and drainage followed by secondary colectomy (n=5) for diverticular perforations in patients with poor general condition. Only one patient (4.5%) died post-operatively of multiple organ failure from generalized peritonitis. There was no anastomotic leakage in patients with primary anastomosis. Six patients (27.2%) developed wound infection. Hospital stay ranged between 11 and 60 days, significantly longer in cases with two-stage operations. Primary colectomy with immediate or delayed anastomosis is the best surgical procedure for acute divericular complications in patients with good biologic status. Two-stage operations such as colostomy and drainage coupled with late colectomy remain the viable alternative in patients with advanced disease and critical biologic condition.

Immune checkpoint inhibitor (ICPI) therapy unleashes the body's natural immune system to fight cancer. ICPIs improve overall cancer survival, however, the unbridling of the immune system may induce a variety of immune-related adverse events. Neuromuscular immune complications are rare but they can be severe. Myasthenia gravis and inflammatory neuropathy are the most common neuromuscular adverse events but a variety of others including inflammatory myopathy are reported. The pathophysiologic mechanism of these autoimmune disorders may differ from that of non-ICPI-related immune diseases. Accordingly, while the optimal treatment for ICPI-related neuromuscular disorders generally follows a traditional paradigm, there are important novel considerations in selecting appropriate immunosuppressive therapy. This review presents 2 new cases, a summary of neuromuscular ICPI complications, and an approach to the diagnosis and treatment of these disorders. Muscle Nerve, 2018. © 2018 Wiley Periodicals, Inc.

Purpose: To evaluate the therapeutic role of angiography in patients with pseudoaneurysms complicating pancreatitis. Methods: Thirteen symptomatic pseudoaneurysms were treated in nine patients with pancreatitis. Eight patients had chronic pancreatitis and pseudocyst and one had acute pancreatitis. Clinical presentation included gastrointestinal bleeding in seven patients and epigastric pain without bleeding in two. All patients underwent transcatheter embolization. Results: Transcatheter embolization resulted in symptomatic resolution in all patients. Rebleeding occurred in two patients, 18 and 28 days after embolization respectively, and was successfully treated by repeated emnbolization. One patient with severe pancreatitis died from sepsis 28 days after embolization. Follow-up was then available for eight patients with no relapse of bleeding after a mean follow-up of 32 months (range 9-48 months). Conclusion: Transcatheter embolization is safe and effective in the management of pseudoaneurysms complicating pancreatitis

Full Text Available Introduction: Several mechanisms are involved in ischemia or mechanical compression of ulnar nerve at the elbow. Presentation of case: We hereby present the case of a road accident victim, who received a radial head excision for an isolated fracture of the radial head and complicated by onset of cubital tunnel syndrome. This outcome could be the consequence of an iatrogenic valgus of the elbow due to excision of the radial head. Hitherto the surgical treatment of choice it is gradually been abandoned due to development of radial head implant arthroplasty. However, this management option is still being performed in some rural centers with low resources. Discussion: The radial head plays an important role in the stability of the elbow and his iatrogenic deformity can be complicated by cubital tunnel syndrome. Conclusion: An ulnar nerve release was performed with favorable outcome. Keywords: Cubital tunnel syndrome, Peripheral nerve palsy, Radial head excision, Elbow valgus
Full Text Available Prosthetic Valve Obstruction (PVO is a serious complication which is associated with increased morbidity and mortality. This could result from thrombus formation, development of pannus, or a combination of both. Patients with this complication often present with symptoms and signs of heart failure, systemic embolism, acute cardiovascular collapse, and sudden death. Transesophageal echocardiography and cine fluoroscopy play a vital role in diagnosis of this potentially lethal condition. Herein, we reported a 56-year-old male patient who presented with severe heart failure and was found to have obstructed ATS27 bileaflet mitral prosthetic valve. Thrombolysis and redo surgery are two important options for treating this condition although guidelines for choosing between the two are not very definite.

Full Text Available Objective. Evaluating the results of respiratory therapy in patients with complicated traumatic injury of the cervical spine.Materials and methods. A retrospective comparative analysis of the clinical course was carried out in 52 patients with complicated traumatic injury of the cervical spine: group A: complete spinal cord injury (ASIA A, 37 patients and group B: incomplete injury (ASIA B, 15 patients. The severity of patients' status on integral scales, parameters of the respiratory pattern and thoracopulmonary compliance, gas composition, and acidbase status of the blood were assessed. Data on patients who required prolonged mechanical ventilation, duration of mechanical ventilation, incidence of nosocomial pneumonia, duration of stay in the ICU, time of hospital treatment, and mortality were included in the analysis. Results. The average APACHE II and SOFA scores were higher in group A patients. The development of the acute respiratory failure required longterm mechanical ventilation (more than 48 hours in 91.4% of group A patients and in 53.3% of group B patients. Ventilatorassociated pneumonia complicated the disease in 81.3% of group A patients and 62.5% of group B patients and was accompanied by sepsis in 25% and 12.5% of cases, respectively. Statistically significant deterioration of biomechanical properties and gas exchange function of the lungs was observed in patients complicated with septic pneumonia.Conclusion. Patients with complicated ASIA A and ASIA B cervical spine injuries demonstrate the presence of respiratory failure of neurogenic origin. In addition, the infectious bronchopulmonary complications aggravated respiratory failure in patients with ASIA A injury in 70.3% versus 33.3% in patients with ASIA B. Developmentof pulmonogenic sepsis led to deterioration of the biomechanical and gas exchange functions of the lungs and increased the likelihood of unfavorable outcome of the disease in 77.8% of cases.

Full Text Available Background: Breast cancer is the most frequent malignant tumor in women worldwide. In recent years, defined reconstruction principles along with numerous surgical techniques with volume replacement have been published. Autologous breast reconstruction is more natural but leaves donor site morbidity. It provides the opportunity to restore the breast mound without the need for scars. This study aims to evaluate the complications of radiotherapy after immediate breast reconstruction with implants in breast cancer patients who submitted to skin sparing mastectomy and nipple sparing mastectomy by taking into consideration the risk factors and management at our institution. Methods: The current study prospectively included patients with invasive breast cancer admitted between January and June 2012 who were scheduled for skin sparing mastectomy or nipple sparing mastectomy and axillary dissection followed by immediate breast reconstruction with implant. Patients received adjuvant chemotherapy followed by conventional fractionated radiation. Complications were classified as either minor or major. The minor complications included capsular contracture (Baker 1-2, seroma, minor skin infection and skin dehiscence without exposure of the implant. Major complications included capsular contracture (Baker 3-4, severe infection and major wound dehiscence with implant exposure. Capsular contracture was scored according to the modified Baker classification. Results: The study included 38 patients. Of these, 28 had skin sparing mastectomy while 10 underwent nipple sparing mastectomy. The overall complication rate was 71%. We observed minor complications in 18 patients while 9 patients had major complications. Complications occurred with a median time of 13 months following radiotherapy completion. All minor complications were managed conservatively whereas all major complications required repeat surgery. No loco-regional recurrences occurred during the follow up

A retroactive computer registration of 459 mammary cancers irradiated at Institut Gustave Roussy from 1967 to 1971 has permitted a qualitative and quantitative study of the sequelli and complications of irradiation of cancer of the breast. These have been subdivided into minor and disabling, and reported according to type of treatment: for 21% local and regional radiation, and for 79% combination radiation and surgery. A limiting dose has been chosen for each treatment volume to correlate total dose and complications. Another method to study the role of the dose is to report complications according to the time of treatment. The final parameter of irradiation analyzed is the variation of complications with NSD. The respective delay in the appearance of complications is expressed. An analyses of these different parameters results in a discussion of prophylactic and therapeutic doses recommended for irradiation of cancers of the breast.

Severe hypertriglyceridemia is a common indication for the need of plasma exchange in treatment of hypertriglyceridemic-induced pancreatitis when normal therapies fail to garner a response. Application of plasmapheresis to prevent complication of hypertriglyceridemia is limited because of its cost and availability. We present a case of a 44-year-old man with metabolic syndrome and a medical history of secondary polycythemia in obesity hypoventilation syndrome, whose laboratory tests revealed a triglycerides value of 3965 mg/dL. To prevent the complication of pancreatitis due to hypertriglyceridemia, we performed plasma exchange 3 times when conventional treatments did not sufficiently reduce the high level of triglycerides. A review of the current available literature was therefore conducted to provide an overview of the present data on apheretic treatment for patients with severe hypertriglyceridemia. Several case reports and case series have used plasmapheresis in acute treatment of hypertriglyceridemia pancreatitis related. In our case, the choice of plasmapheresis was applied in prevention of possible complications of hypertriglyceridemia.

An immune-enhancing diet has been used to alter eicosanoid synthesis, cytokine production, and immune function in an attempt to limit the undesired immune reactions after injury from surgery. This prospective randomized study was designed to investigate the effect of preoperative immunonutrition on operative complications, and the participation of prostaglandin E2 (PGE2) on T-cell differentiation in patients undergoing a severely stressful surgery. The enrolled patients who were scheduled to undergo pancreatoduodenectomy were randomized into two groups. Patients in the immunonutrition group (n = 25) received oral supplementation containing arginine, ω-3 fatty acids, and RNA for 5 days before the procedure in addition to a 50% reduction in the amount of regular food. Patients in the control group (n = 25) received no artificial nutrition and were allowed to consume regular food before surgery. All patients received early postoperative enteral infusion of a standard formula intended to provide 25 kcal/kg/day. The primary endpoint was the rate of infectious complications; the secondary endpoint was immune responses. This study is registered with ClinicalTrials.gov (NCT01256034). Infectious complication rate and severity of complications (Clavien-Dindo classification) were lesser in the immunonutrition group than in the control group. mRNA expression levels of T-bet were greater in the immunonutrition group than in the control group (P production and T-cell differentiation and may protect against the aggravation of operative complications in patients undergoing pancreatoduodenectomy.

To evaluate the radiographic and CT findings of pulmonary complications other than pulmonary edema arising from renal transplantation. Among 393 patients who had undergone renal transplantation at our hospital during a previous ten-year period, 23 with pulmonary complications other than pulmonary edema were included in this study. The complications involved were infection caused by CMV (n=6), bacteria (n=4), fungus (n=4), tuberculosis (n=2), varicella (n=1) or chlamydia (n=1), and malignancy involving lung cancer (n=4) or Kaposi's sarcoma (n=1). Two chest radiologists reviewed all images. The complications manifesting mainly as pulmonary nodules were lung cancer (4/4), tuberculosis (1/2), and Kaposi's sarcoma (1/1). Pulmonary consolidation was a main feature in bacterial infection (4/4), fungal infection (3/4), tuberculosis (1/2), chlamydial infection (1/1), and varicellar pneumonia (1/1). Ground-glass attenuation was a main CT feature in CMV pneumonia (4/6), and increased interstitial making was a predominant radiographic feature in CMV pneumonia (2/6). The main radiologic features described above can be helpful for differential diagnosis of the pulmonary complications of renal transplantation.

The current that flows between the electrical test equipment and the nuclear explosive must be limited to safe levels during electrical tests conducted on nuclear explosives at the DOE Pantex facility. The safest way to limit the current is to use batteries that can provide only acceptably low current into a short circuit; unfortunately this is not always possible. When it is not possible, current limiters, along with other design features, are used to limit the current. Three types of current limiters, the fuse blower, the resistor limiter, and the MOSFET-pass-transistor limiters, are used extensively in Pantex test equipment. Detailed failure mode and effects analyses were conducted on these limiters. Two other types of limiters were also analyzed. It was found that there is no best type of limiter that should be used in all applications. The fuse blower has advantages when many circuits must be monitored, a low insertion voltage drop is important, and size and weight must be kept low. However, this limiter has many failure modes that can lead to the loss of over current protection. The resistor limiter is simple and inexpensive, but is normally usable only on circuits for which the nominal current is less than a few tens of milliamperes. The MOSFET limiter can be used on high current circuits, but it has a number of single point failure modes that can lead to a loss of protective action. Because bad component placement or poor wire routing can defeat any limiter, placement and routing must be designed carefully and documented thoroughly.

Full Text Available BACKGROUND: Clostridium difficile infection (CDI can lead to complications, recurrence, and death. Numerous studies have assessed risk factors for these unfavourable outcomes, but systematic reviews or meta-analyses published so far were limited in scope or in quality. METHODS: A systematic review was completed according to PRISMA guidelines. An electronic search in five databases was performed. Studies published until October 2013 were included if risk factors for at least one CDI outcome were assessed with multivariate analyses. RESULTS: 68 studies were included: 24 assessed risk factors for recurrence, 18 for complicated CDI, 8 for treatment failure, and 30 for mortality. Most studies accounted for mortality in the definition of complicated CDI. Important variables were inconsistently reported, such as previous episodes and use of antibiotics. Substantial heterogeneity and methodological limitations were noted, mainly in the sample size, the definition of the outcomes and periods of follow-up, precluding a meta-analysis. Older age, use of antibiotics after diagnosis, use of proton pump inhibitors, and strain type were the most frequent risk factors for recurrence. Older age, leucocytosis, renal failure and co-morbidities were frequent risk factors for complicated CDI. When considered alone, mortality was associated with age, co-morbidities, hypo-albuminemia, leucocytosis, acute renal failure, and infection with ribotype 027. CONCLUSION: Laboratory parameters currently used in European and American guidelines to define patients at risk of a complicated CDI are adequate. Strategies for the management of CDI should be tailored according to the age of the patient, biological markers of severity, and underlying co-morbidities.

To discuss the potentially significant complications associated with medial patellofemoral ligament (MPFL) reconstruction. Additionally, to review the most current and relevant literature with an emphasis on avoiding these potential complications. Multiple cadaveric studies have characterized the anatomy of the MPFL and the related morphologic abnormalities that contribute to recurrent lateral patellar instability. Such abnormalities include patella alta, excessive tibial tubercle to trochlear grove (TT-TG) distance, trochlear dysplasia, and malalignment. Recent studies have evaluated the clinical outcomes associated with the treatment of concomitant pathology in combination with MPFL reconstruction, which is critical in avoiding recurrent instability and complications. Although there remains a lack of consensus regarding various critical aspects of MPFL reconstruction, certain concepts remain imperative. Our preferred methods and rationales for surgical techniques are described. These include appropriate work up, a combination of procedures to address abnormal morphology, anatomical femoral insertion, safe and secure patellar fixation, appropriate graft length fixation, and thoughtful knee flexion during fixation.

Full Text Available OBJECTIVE: It was to report on Brazilian cases of neurological complications from bariatric surgery. The literature on the subject is scarce. METHOD: Cases attended by neurologists in eight different Brazilian cities were collected and described in the present study. RESULTS: Twenty-six cases were collected in this study. Axonal polyneuropathy was the most frequent neurological complication, but cases of central demyelination, Wernicke syndrome, optical neuritis, radiculits, meralgia paresthetica and compressive neuropathies were also identified. Twenty-one patients (80% had partial or no recovery from the neurological signs and symptoms. CONCLUSION: Bariatric surgery, a procedure that is continuously increasing in popularity, is not free of potential neurological complications that should be clearly presented to the individual undergoing this type of surgery. Although a clear cause-effect relation cannot be established for the present cases, the cumulative literature on the subject makes it important to warn the patient of the potential risks of this procedure.

We reviewed the files of 80 successive patients with native and prosthetic valve endocarditis admitted to Riyadh Armed Forces Hospital. Neurolological complications (NC) occurred in 28 (35%) patients. The valves involved were mitral in 12 (43%), aortic in eight (29%), combined mitral and aortic lesions in six (21%) and others in two (7%). The common causative organisms were Streptococci in 12 (43%), Staphylococcus aureus and Staphylococcus epidermides, both occurring in four (14%). Compared to the 52 infective endocarditis patients with no neurological complications (NNC), the NC occurred more frequently in male patients, those with aortic valve lesion, those with atrial fibrillation, those with delayed therapy and those with causative organisms being Streptococci or Staphylococci. Eleven patients died (39%), 12 (43%) recovered with motor sequelae, six (21%) had seizure disorder and five (18%) had full recovery. The frequency of neurological complications and mortality is comparable to those reported in the literature: however, the frequency was higher in our patients. (author)

Chronic obstructive pulmonary disease (COPD) is defined as a syndrome characterized by usually progressive chronic airflow limitation which is associated to a bronchial hyperresponsiveness and is partially reversible. Noninvasive mechanical ventilation is an alternative treatment for patients with COPD exacerbations. The objective of the literature reviews was to verify noninvasive mechanical ventilation benefits and complications in acute exacerbations of chronic obstructive pulmonary disease in patients. This national and international's scientific literature review was developed according to criteria established for documentary research in the MedLine, LILACS, SciElo, PubMed and Cochrane, databases using the key words: chronic obstructive pulmonary disease and noninvasive mechanical ventilation. Inclusion criteria were articles published from 1995 to 2007; in English, Spanish and Portuguese; studies in the human model and with no gender restriction. Noninvasive mechanical ventilation can reduce partial pressure of carbon dioxide, improve gas exchange, alleviate symptoms as dyspnea caused by fatigue of the respiratory muscles, reduce duration of hospitalization, decrease need for invasive mechanical ventilation, reduce number of complications and also lessen hospital mortality. The main complications found were: facial skin erythema, claustrophobia, nasal congestion, face pain, eye irritation, aspiration pneumonia, hypotension, pneumothorax, aerophagia, hypercapnia, gastric insufflation, vomit, bronchoaspiration, morning headaches, face injuries, air embolism and, last but not least, discomfort of the patient. Noninvasive mechanical ventilation can be more effective in patients with moderate-severe exacerbations of COPD and these complications can be minimized by an adequate interface also by the contribution of the physiotherapist experience.

Gastro-oesophageal reflux disease (GORD) is on the rise with more than 20% of the western population reporting symptoms and is the most common gastrointestinal disorder in the United States. This increase in GORD is not exactly clear but has been attributed to the increasing prevalence of obesity, changing diet, and perhaps the decreasing prevalence of H. pylori infection. Complications of GORD could be either benign or malignant. Benign complications include erosive oesophagitis, bleeding and peptic strictures. Premalignant and malignant lesions include Barrett's metaplasia, and oesophageal cancer. Management of both the benign and malignant complications can be challenging. With the use of proton-pump inhibitors, peptic strictures (i.e., strictures related to reflux) have significantly declined. Several aspects of Barrett's management remain controversial including the stage in the disease process which needs to be intervened, type of the intervention and surveillance of these lesions to prevent development of high grade dysplasia and oesophageal adenocarcinoma.

Full Text Available The main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. Also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. Due to the above mentioned problems and in order to solve and minimize them nasal packing, nasal splint and nasal mold have been advised. Patients for whom the nasal packing used may faced to some problems like naso-pulmonary reflex, intractable pain, sleep disorder, post operation infection and very dangerous complication like toxic shock syndrome. We have two groups of patients and three surgeons (one of the surgeons used post operative nasal packing in his patients and the two others surgeons did not.Complications and morbidities were compared in these two groups. Comparing the two groups showed that the rate of complication and morbidities between these two groups were same and the differences were not valuable, except the pain and discomfort post operatively and at the time of its removal. Nasal packing has several risks for the patients while its effects are not studied. Septoplasty can be safely performed without postoperative nasal packing. Nasal packing had no main findings that compensated its usage. Septal suture is one of the procedures that can be used as alternative method to nasal packing. Therefore the nasal packing after septoplasty should be reserved for the patients with increased risk of bleeding.

Intracraneal bleeding is a rare complication after raquis surgery. It is believed to occur as a drop in the intracraneal pressure after a loss of CSF secondary to an iatrogenic dural tear. We report a patient who after surgery for lumbar stenosis presented a subarachnoid haemorrhage, an intraparenchymal haematoma, and a subdural haematoma. To our knowledge, this is the first report in the literature with such complications after this type of surgery. Copyright © 2017 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.

We report a case each of duodenorenal and colorenal fistula that arose after computed tomography-guided percutaneous cryoablation (PCA) for renal cell carcinoma and use imaging and endoscopic findings to analyze their causes and mechanisms. Both complications occurred though the edge of the iceball did not touch the intestinal wall, and patients’ symptoms and fistula formation occurred several days after the PCA procedure. Based on imaging and endoscopy findings, we suspected the colorenal fistula resulted from bowel injury caused by ischemia from the occlusion of small vessels at the procedure’s low temperature. Both cases were resolved conservatively without surgical intervention.

Gestational diabetes insipidus (GDI) is a rare, self-limited complication of pregnancy. As it is related to excess placental vasopressinase enzyme activity, which is metabolized in the liver, GDI is more common in pregnancies complicated by conditions associated with liver dysfunction. We present a case of a 41-year-old woman at 38 weeks' gestation who presented with pre-eclampsia with severe features, including impaired liver function and renal insufficiency. Following cesarean section she was diagnosed with GDI, which was further complicated by cerebral vasoconstriction as demonstrated by magnetic resonance angiography. This case raises the possibility that cerebral vasoconstriction may be related to the cause of GDI. A high index of suspicion of GDI should be maintained in patients who present with typical signs and symptoms, especially in the setting of pregnancy complications associated with liver dysfunction. © 2015 The Authors.

Full Text Available Two cases of fibrous myopathy associated with repeated, long-term intramuscular injections for treatment of chronic temporomandibular joint pain and chronic headache, respectively, are described. Both patients developed severe, function-limiting contractures in upper and lower extremity muscles used as injection sites. In one of the cases, the contractures were painful. Electrophysiological testing, magnetic resonance imaging and muscle biopsy results were all consistent with myopathy and replacement of skeletal muscle with noncontractile fibrous tissue. These cases are presented to increase awareness of fibrous myopathy and to promote surveillance for this serious potential complication of long-term intramuscular injections in chronic headache and other pain patients.
With thirteen beam induced quenches and numerous Machine Development tests, the current knowledge of LHC magnets quench limits still contains a lot of unknowns. Various approaches to determine the quench limits are reviewed and results of the tests are presented. Attempt to reconstruct a coherent picture emerging from these results is taken. The available methods of computation of the quench levels are presented together with dedicated particle shower simulations which are necessary to understand the tests. The future experiments, needed to reach better understanding of quench limits as well as limits for the machine operation are investigated. The possible strategies to set BLM (Beam Loss Monitor) thresholds are discussed. (author)

In addition, 1 patient developed acute renal failure 26 hours after the IV-DSA, whereas 4 patients later showed on thromboses of the catheterised vein. No permanent neurologic or systemic complications and severe allergic reactions were seen. (orig.) [de
X-ray investigation is a leading diagnostic modality in case of purulent destructive diseases, especially with the purpose to correct the treatment and determining the indications to surgery. Almost in half of the patients (46.5 %), the course is complicated by the development of one or several accompanying pathological processes (pleurisy, empyema, gangrene, etc), which complicate the course and require additional therapeutic measures, frequently determining the outcome of the disease.
