Six weeks after presumptive acute synovial rupture at the knee, a patient was admitted with cutaneous induration over the medial calf. Roentgenograms showed gas shadows within the involved area. A fluctuant area at the center of the indurated mass yielded a Corynebacterium species.
The neuropathological findings in six patients who developed neurological signs after the onset of "septic shock" caused by Gram-negative septicaemia are described. The changes in the brains were characteristic of acute haemorrhagic leucoencephalitis, and there was evidence, particularly in the kidneys, of disseminated intravascular coagulation with tubular necrosis and, in some, appearances indistinguishable from membrano-proliferative glomerulonephritis. It is agreed that acute haemorrhagic leucoencephalitis is another manifestation of a generalised Shwartzman reaction, and it is suggested that activation of complement is the final common pathway that produces tissue damage in the brain and kidney.

AIMS: People with depressive disorder have increased premature mortality and higher rates of diabetes mellitus than general population. Evidence shows that diabetes may further increase their risk of premature death from diabetes-related complications, especially cardiovascular diseases (CVDs). Earlier studies examining depression-associated outcomes in diabetes patients have shown mixed results and were hindered by important limitations, especially the use of self-reported questionnaires to ascertain depression, causing misclassification bias by identifying subclinical symptoms or diabetes distress. Associations of depression with specific diabetes complications have not been systematically evaluated. This meta-analysis aimed to investigate the risk of mortality and complications among patients with depression and co-occurring diabetes (depression-diabetes group) relative to patients with diabetes-only (diabetes-only group), on their all-cause mortality rates, and if applicable cause-specific mortality rates, and occurrence of specific diabetes complications. METHODS: We systematically reviewed and quantitatively synthesized diabetes-related outcomes in patients with depression by searching Embase, MEDLINE, PsycInfo and Web-of-Science from inception to 20 December 2024, and included studies that examined mortality and complication outcomes in depression-diabetes group relative to diabetes-only group. Results were synthesized by random-effects meta-analytic models, with stratified-analyses (subgroup analyses and meta-regression) by study-level characteristics, including age, gender, study period, geographic region, follow-up duration and nature of diabetes sample. The study was registered with PROSPERO (CRD42024595145). RESULTS: Twenty-six studies were identified from nine geographic regions. Regarding mortality risk, depression-diabetes group exhibited increased risks of all-cause mortality (RR = 1.30 [95% CI: 1.21-1.39]) and CVD-specific mortality (1.15 [1.02-1.29]) relative to diabetes-only group. Regarding complication risk, depression-diabetes group showed increased risk of complications (1.28 [1.18-1.40]) relative to diabetes-only group, especially in incident-diabetes sample signifying advanced disease stage upon presentation, with stratified-analyses showing higher risk of metabolic complications (1.63 [1.33-1.99]) and cardiovascular complications (1.20 [1.11-1.29]), and lower likelihood of retinopathy (0.84 [0.76-0.94]), albeit comparable rates of cerebrovascular complications (1.36 [0.99-1.87]), nephropathy (1.09 [0.93-1.27]) and peripheral-vascular complications (0.97 [0.79-1.18]). Both overall mortality and complication risks were present in various regions and persisted over time. Heterogeneities were noted and could not be entirely explained by stratified analyses. CONCLUSIONS: Our study demonstrated that patients with depression and co-occurring diabetes were associated with elevated overall mortality risk and complication risk (particularly metabolic and cardiovascular-complications) than non-depressed counterparts, suggesting an overall poorer glycemic control that might eventually drive their earlier death. Comprehensive and multipronged interventions are needed for individualized risk estimation of diabetes-related outcomes, with consequent early interventions to minimize the avoidable physical morbidity and premature mortality in this vulnerable population.
1. Patients with complications when compared with those not developing a complication: a. Were older, 44.4 vs. 34.5 years; b. Were monitored longer, 14.0 vs. 6.5 days; c. Were treated with steroids longer, 18.3 vs. 10.3 days; d. Were hospitalized longer, 35.7 vs. 27.7 days; e. Are twice as likely to die; f. Average age of those dying is older, 46 vs. 30 years; g. Have no clear relationship to antibiotics; h. Do not have a preponderance of single diagnostic category to account for these differences; i. Complications were always controlled with standard therapy; j. An ICP complication was almost never responsible, per se, for death. 2. Over all complication rate was 18%; due to monitoring was 4.5 to 11.5%. 3. Monitoring was responsible for, or contributed to, 25 to 60% of the complications. 4. No complications occurred when monitoring was discontinued within 3 days. 5. Long periods of treatment with steroids increased the risk of a complication developing. 6. Long periods of monitoring were associated with an increased risk of complication. 7. "Individual" factors are partly responsible for the development of a complication, and death. 8. There are two groups of complications: "early" and "late." A. Those most likely to be monitor related occur "late" and account for 35% of the complications. B. Those developing "early" infection account for 65% of the complications and are most likely caused by factors other than monitoring. While there are complications directly attributable to monitoring, the rate is low and they are readily controlled by standard neurosurgical management. While monitoring may increase the morbidity, it does not increase the mortality. We feel that the over-all risk is small and that the returns are great--both in terms of knowledge and patient benefit.
BACKGROUND/OBJECTIVE: Chronic vascular complications are the primary threat in long-standing type 1 diabetes (T1D) patients. We examined the associations between oral-gut microbiome dysbiosis and these complications, offering novel insights into therapeutic strategies and underlying mechanisms. METHODS: This cross-sectional study enrolled 75 T1D participants (disease duration ≥ 10 years) and 43 healthy controls who underwent comprehensive clinical assessment, including blood glucose, lipid profile, and complication-related examinations. Fecal and oral rinse samples were collected for shotgun metagenomic sequencing. T1D participants were stratified by the presence of microvascular (retinopathy, nephropathy, or neuropathy) or macrovascular complications separately. Microbial differences across groups were assessed. RESULTS: Significant differences in oral and gut microbiota compositions were observed between T1D participants with and without complications (both microvascular and macrovascular). A core set of 26 gut and 8 oral microbial species was specifically associated with vascular complications. Butyrate-producing gut bacteria (Blautia wexlerae, Anaerobutyricum hallii, Roseburia inulinivorans, A. soehngenii) and specific oral Neisseria species were enriched in T1D without complications individuals, suggesting protective effects against complications. Mediation analysis indicated associations consistent with partial mediation between certain microbial species and the relationships of glycemic control or insulin resistance (HbA1c, glucose risk index, estimated glucose disposal rate) with complication risk. Moreover, potential oral-gut microbiome interconnections were implicated in complication development. Finally, classification models integrating both oral and gut microbial features significantly outperformed models based on either site alone in distinguishing T1D patients with complications. CONCLUSIONS: Distinct oral and gut microbiome features are associated with chronic vascular complications in T1D. These findings highlight the potential of microbiome-targeted strategies for understanding and preventing T1D-related complications.
Sickle cell disease (SCD) is characterized by both acute and chronic complications. The clinical manifestation of these complications differs between genotypes. Given the large amount of research already published, this systematic review aims to offer a complete overview of types of sickle cell complications between adults in the most common genotypes Hemoglobin SS (HbSS) and Hemoglobin SC (HbSC), putting options for further research into perspective. An extensive literature search was performed to study all available evidence on these complications. This review was performed according to the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) statement guidelines, and was performed on January 2, 2024. A total of 710 references were identified. After careful screening, 521 records were excluded based on title and abstract and other exclusion criteria. In total, 158 articles were excluded after full-text assessment. Our analysis of 31 studies highlights key differences in complications between HbSS and HbSC genotypes in sickle cell disease (SCD). Vaso-occlusive crises (VOCs) remain the most common acute complication in both genotypes. HbSS patients experience more frequent VOCs, while HbSC patients generally have a milder clinical course when it comes to acute complications. Chronic complications, particularly in the ocular and pulmonary systems, are more prevalent in HbSC patients. However, as acute complications are more common in HbSS and chronic complications more common in HbSC, both genotypes face progressive organ damage due to recurrent ischemic injury and inflammation.
The hospital and office records of patients undergoing major surgery for cancer of the larynx and hypopharynx at the Washington University Medical Center, St. Louis from 1955 to 1972 were reviewed. Study parameters were correlated with the incidence of major complications and statistically analyzed to elucidate what factors contribute to increased complication rates. Abnormal margins of surgical resection were found to be significant in determining subsequent complication. Age, sex, race, site and stage of the primary tumor, and the presence of pre-treatment cervical lymph node fixation did not alter the rate of complications. Similarly, low dose preoperative irradiation, various forms of carotid artery protection, and surgical patholgic findings including the size of the tumor, number of positive cervical nodes and cellular characteristics of the tumor showed no significant effect on the rate of complications. Increased total complication rate was associated with an increased death rate. Common complications included wound infection, wound necrosis, salivary fistula, hemorrhage, and carotid artery catastrophe. Also considered were operative deaths and delayed fatal complications. The common causes and treatment of these complications are outlined and safeguards which have been valuable in a sizeable number of patients are discussed.
In a period of two years, 202 kidneys were transplanted in 162 patients at the Downstate Medical Center. On hundred twenty-nine patients had primary transplantations, twenty-nine second transplantations, and five third transplantations. Urologic complications occurred in twenty-four of the patients (12%). There were eight complications involving the urinary bladder and fifteen ureteric complications. In twenty-one patients the complications appeared within six weeks after surgery. Surgical correction immediately upon diagnosis of the urinary complications resulted in a high degree of early restoration of the urinary tract continuity and preservation of renal function. Leakage from the bladder was frequently associated with previous surgery. In five of eight patients, bladder leakage occurred after the second or third transplantations. Complications of the urinary bladder in general had a significantly favorable prognosis as compared with ureteric complications. Although all the patients with bladder complications fully recovered and maintained good renal function, four patients with ureteric complications either died or lost the graft.
A retrospective analysis of 123 pediatric tracheostomies reveals an overall complication rate of 33%. Immediate complications were present in 12% or 15 patients. The most frequent immediate complications were pneumomediastinum and pneumothorax. Delayed complications occurred in 24% or 30 patients. The most frequent delayed complications were subglottic stenosis, fused vocal cords, and tracheal granuloma. Four patients died because of tracheostomy-related complications. Age, underlying disease, and prior endotracheal intubation had a high degree of correlation with complications. The use of a mechanical respirator following tracheostomy did not appear to be significantly related to complications. Fifty percent of the delayed complications in this series were regarded as being unrelated to the tracheostomy or the trachesotomy tube itself.
Esophagogastroduodenoscopy (211,410 examinations) had a complication rate of 1.3/1,000 cases. Duodenoscopy with cannulation was performed 3,884 times and had a complication rate of 21.6/1,000 examinations. Diagnostic coloscopy (25,298 examinations) had a complication rate of 3.4/1,000. Polypectomies during coloscopy (6,124 cases) had a complication rate of 23.3/1,000 cases. Esophageal dilations (13,139 cases) had a complication rate of 4.25 with mercury bougies, and in 9,431 cases metal olives produced a complication rate of 6.1/1,000 treatments. Dilation for achalasia in 1,224 patients produced a complication rate of 18.4/1,000 procedures. Peritoneoscopy (4,404 examinations) produced a complication rate of 5.4/1,000 patients. The value of these diagnostic and therapeutic procedures is now well established but must be weighed against a potential risk of complications.
BACKGROUND: Brucellosis is a multi-systemic zoonotic infection. The West Asia/Middle East region is an important global hotspot for brucellosis. This systematic review and meta-analysis aimed to aggregate and synthesize all the available evidence regarding the complications of brucellosis in West Asia/Middle East region. METHODS: PubMed, Embase, Scopus, Web of Science, Google Scholar, and Proquest were searched. Selection of studies, data extraction, and the risk of bias assessment were performed in duplicate. Data extraction was performed for 254 complications. Meta-analysis was performed using a random-effects model with Freeman-Tukey double arcsine transformation. Where applicable small-study effects was assessed using funnel plots and Egger's test. Separate by-country, by-age, and by-publication-decade subgroup analyses were performed if feasible. RESULTS: Out of 9518 results, 240 studies (260 references) were included. The majority of the included studies were conducted in Turkey (n = 177). The reported complications varied and different complication categorization systems were detected. The highest pooled estimate was observed for musculoskeletal involvement (50%, 95%CI: 39%-61%, I2 = 96.63%). The evidences is up-to-date until March 4, 2024. CONCLUSIONS: Some complications such as the complications of the eye were not reported in all the countries. Therefore, it's recommended to determine the relative frequency of those complications in regions without such reports. The pooled estimates of different complications of brucellosis were different. There's a need for the standardization of the reporting of the complications of brucellosis to achieve comparability between studies and across different regions.
