Machine learning-based clinical tool for identifying factors associated with symptomatic knee osteoarthritis: the Nagahama study.

BACKGROUND: A clinical tool that evaluates factors associated with symptomatic knee osteoarthritis (OA) based on modifiable factors is lacking. This study aimed to develop a machine learning-based clinical assessment tool using modifiable factors to identify factors associated with symptomatic knee OA and to determine its accuracy. METHODS: This study included 429 participants (81.8% women; age, 69.0 ± 5.3 years) from the Nagahama Study who were ≥60 years old and had radiographically confirmed knee OA. A Knee Society Knee Scoring System 2011 symptom score of <23 points defined symptomatic knee OA. Participants were randomly assigned to training (70%) and test (30%) datasets. A machine learning model was developed using Extreme Gradient Boosting with 27 variables, and the SHapley Additive exPlanation (SHAP) values were used to assess feature importance. The top 8 features were translated into a 100-point clinical scoring tool weighted by their SHAP contributions. The cutoff value indicating symptomatic knee OA in the clinical assessment tool was determined using receiver operating characteristic analysis, and model performance was evaluated in both datasets. RESULTS: The clinical assessment tool consisted of low back pain, OA severity, depressive tendencies, knee flexion/extension range of motion, knee extension and hip abduction strength, and lower limb muscle quality. The model showed moderate discriminative performance (AUC 0.771 and 0.773 in the training and test datasets, respectively), with a cutoff point of 47. CONCLUSION: The proposed clinical assessment tool may provide a structured framework for assessing modifiable factors associated with symptomatic knee OA, reflecting their contribution to current symptom status.

Comparison of phylogenetic metrics of transmission between symptomatic and asymptomatic tuberculosis in individuals who were incarcerated in Brazil in 2008-24: a retrospective genomic epidemiology study.

BACKGROUND: Tuberculosis control efforts have traditionally targeted symptomatic individuals; however, the role of asymptomatic cases in sustaining transmission is increasingly recognised. We aimed to quantify the contribution of asymptomatic tuberculosis to recent transmission using genomic and epidemiological data from a high-transmission setting. METHODS: We conducted a retrospective genomic epidemiology study of Mycobacterium tuberculosis isolates collected in Mato Grosso do Sul, Brazil, between Aug 25, 2008, and March 19, 2024. Available isolates underwent whole-genome sequencing. Demographic, clinical, incarceration history, and laboratory metadata were obtained from surveillance records. From Jan 1, 2017, to March 19, 2024, active case finding was conducted in the state's three largest prisons (all male-only facilities), during which sputum samples were collected from individuals irrespective of symptoms and tested using GeneXpert and culture. Comparisons of transmission between individuals with and without symptoms were restricted to individuals who were incarcerated and were identified through active case finding and for whom high-quality, M tuberculosis lineage 4 genomes were available. Metrics of recent transmission included phylogenetic clustering, time-scaled haplotype density (THD), local branching index (LBI), and transmission probabilities inferred using Bayesian Reconstruction and Evolutionary Analysis of Transmission Histories. FINDINGS: 4448 tuberculosis cases were notified in Mato Grosso do Sul in 2008-24. After excluding cases for which M tuberculosis isolates were not available or had low sequencing quality, who had contaminated cultures or mixed infection, or who were infected with non-lineage 4 M tuberculosis, we included 2362 lineage 4 M tuberculosis isolates with high-quality genome sequences. 1849 (78·3%) of 2362 isolates were part of a genomic cluster. Among 2362 individuals with tuberculosis, 1137 (48·1%) were incarcerated at diagnosis. Of these individuals, 505 were identified through active case finding in three male-only prisons. The median age was 30 years (IQR 25-37); 304 (60·2%) had mixed ethnicity, 90 (17·8%) were White, 56 (11·1%) were Black, 13 (2·6%) were Indigenous, and six (1·2%) were Asian. 277 (54·9%) had symptomatic disease and 228 (45·1%) had asymptomatic tuberculosis. There were no significant differences between symptomatic and asymptomatic individuals in phylogenetic clustering (213 [76·9%] of 277 vs 195 [85·5%] of 228; p=0·37), THD (median 0·39 [IQR 0·06-0·62] vs 0·50 [0·09-0·65]; p=0·12), or LBI (0·00863 [0·00810-0·00988] vs 0·00871 [0·00829-0·01020]; p=0·088). Bayesian transmission trees showed no significant difference in the number of secondary infections inferred from symptomatic compared with asymptomatic individuals (p=0·56). These findings were consistent across genomic clusters and robust to model assumptions. INTERPRETATION: We identified no differences in transmission between individuals who were symptomatic and those who were asymptomatic using multiple genomic measures. In this high-transmission setting, where systematic screening is implemented, our findings indicate that asymptomatic tuberculosis substantially contributes to tuberculosis transmission at the population level. These results suggest that symptom-based case detection alone is likely to be insufficient to interrupt transmission and highlight the importance of expanded screening strategies in high-risk populations.

Trichomonas vaginalis: random amplified polymorphic DNA analysis of isolates from symptomatic and asymptomatic women in India.

Trichomonas vaginalis, the causative agent for human trichomoniasis, is a protozoan parasite. Trichomoniasis is the most common non-viral sexually transmitted disease. The infection in women may be asymptomatic or may lead to severe vaginitis, cervicitis and severe sequelae. Despite its high prevalence, the genetic variability and factors leading to symptomatic infection have been poorly understood. One thousand women in childbearing age group were screened for the presence of T vaginalis. Thirty-eight women were found positive for T vaginalis and out of these 22 (57.9%) were having symptomatic infection and 16 (42%) were asymptomatic. Fresh isolates from 15 symptomatic and 15 asymptomatic women were axenised and subjected to random amplified polymorphic DNA (RAPD) analysis with the use of five different random primers (OPD 1-OPD 5). The isolates with similar banding pattern were assigned as a single type. OPD 3 indicated least (nine types) while OPD 4 indicated highest typing (18 types) ability. Phylogenetic analysis using RAPD distance software indicated two distinct lineages; upper branch consisting of only seven symptomatic isolates while lower branch consisting of all the 15 asymptomatic isolates the other eight symptomatic isolates were recorded in separate cluster. The study indicated that RAPD technique might be helpful to delineate the pathogenic mechanism(s) for its virulence; however, further studies on large number of isolates are desired to elucidate the findings.

Long-term durability of laparoscopic decortication of symptomatic renal cysts.

OBJECTIVES: To assess the long-term results of patient symptoms and radiologic outcomes of laparoscopic renal cyst decortication in the treatment of symptomatic simple renal cysts. Renal cysts are common in the adult population. Symptomatic renal cysts have traditionally been treated by percutaneous aspiration with or without injection of sclerosant agents; however, this has a high rate of recurrence. METHODS: From April 1994 through July 2005, 45 patients underwent laparoscopic decortication of symptomatic simple renal cysts with renal cyst wall excision and fulguration of the epithelial lining. Complex renal cysts were excluded. Of the 45 patients, 24 (53.3%) had undergone previous cyst aspiration with injection of sclerosant material for intended ablation. The Wong-Baker pain scale was used to assess the preoperative and postoperative pain scores. Radiologic success was indicated as no recurrence on the most recent computed tomography scan. RESULTS: Of the 45 procedures, 44 were completed laparoscopically. One patient (1.8%) underwent open conversion because of excessive bleeding. The mean operative time was 89 minutes (range 48 to 170). Symptomatic success was achieved in 91.1% of patients, with a median follow-up of 52 months (range 3 to 132), and radiographic success was achieved in 95.5% of patients, with a median follow-up of 39 months (range 3 to 96). CONCLUSIONS: Long-term follow-up has confirmed that laparoscopic cyst decortication is an effective and durable treatment option for symptomatic simple renal cysts during long-term follow-up. The greater and durable success rates of this minimally invasive technique may favor this treatment option over other treatment modalities.

Evaluation of transformation growth factor beta1, interleukin-10, and interferon-gamma in male symptomatic and asymptomatic dogs naturally infected by Leishmania (Leishmania) chagasi.

The aims of this study were to evaluate the immunomodulatory role of TGF-beta1, IL-10, and INF-gamma in spleen and liver extracts and supernatant cultures of white spleen cells from male symptomatic and asymptomatic dogs, naturally infected by Leishmania (Leishmania) chagasi. Thirty dogs from Araçatuba, São Paulo, Brazil, an endemic leishmaniosis area, were selected by positive ELISA serological reaction for Leishmania sp. and divided into two groups: asymptomatic (n=15) and symptomatic (n=15) consisting of animals with at least three characteristic signs (fever, dermatitis, lymphoadenopathy, onychogryphosis, weight loss, cachexia, locomotion problems, conjunctivitis, epistaxis, hepatosplenomegaly, edema, and apathy). After euthanasia, spleen and liver fragments were collected for ex vivo quantification of TGF-beta1, IL-10, and INF-gamma. Naturally active in vitro produced TGF-beta1 was also evaluated in spleen cell culture supernatant. Spleen and liver extract of asymptomatic dogs had higher mean TGF-beta1 levels than symptomatic dogs. High concentrations of IL-10 were found in spleen, and mainly in liver extract of both groups. Higher INF-gamma concentrations were found in spleen extracts of symptomatic dogs, and in liver extracts of asymptomatic dogs. Extract of this cytokine was lower in spleen extract. Although INF-gamma is being produced in canine infection, mean levels of TGF-beta1 and IL-10 from spleen and liver extracts were quantitatively much higher; suggesting that immune response in both asymptomatic and symptomatic dogs was predominantly type Th2.

Goals of therapy and guidelines for treatment success in symptomatic gastroesophageal reflux disease patients.

Important new data have established symptomatic gastroesophageal reflux disease (GERD) as a disorder in its own right. Despite major advances in management, this disorder still presents many challenges. With the absence of visible disease (i.e., esophageal erosions), symptom relief must be a primary aim in treating patients with symptomatic GERD; in particular, reflux patients suffer from several different symptoms, but relief of heartburn and acid regurgitation should be the principal concern in clinical practice. Epigastric pain and other upper GI symptoms usually improve with active treatment. From a methodological standpoint, complete symptom relief is an attractive outcome measure. However, not all patients expect complete absence of symptoms in the long term, and many reflux patients are willing to continue a treatment strategy that provides substantial but less than absolute symptom control. Patients with symptomatic GERD have significantly impaired health-related quality of life (HRQOL) which, when heartburn is resolved, often improves to levels equal to or better than that found in the normal, healthy population. However, some reflux sufferers may not report symptoms and have apparently normal HRQOL measures owing only to the fact that they self-impose rigorous lifestyle restrictions to prevent heartburn-restrictions that may, in turn, eventually lead to HRQOL impairment. A full and complete evaluation of treatment success should be able to detect this pattern. Data on the long-term prognosis and risk of complications associated with treatment for symptomatic GERD are scarce and incomplete. However, the prevention of erosive esophageal damage, strictures, and adenocarcinoma should be a goal of long-term treatment success, even in symptomatic GERD.

Repair of Ebstein's anomaly in the symptomatic neonate: an evolution of technique with 7-year follow-up.

BACKGROUND: Ebstein's anomaly in the severely symptomatic neonate is usually fatal. Until recently, successful repair has not been reported and various palliative operations have been associated with prohibitive mortality. Recently, we published our initial results with biventricular repair in 3 severely symptomatic neonates. We now update our experience with emphasis on the evolution of our surgical technique and the medium-term follow-up of these patients. METHODS: Since 1994, 8 severely symptomatic neonates and young infants underwent biventricular repair by one surgeon. Six had Ebstein's anomaly and 2 had physiologically similar pathology with severe tricuspid valve dysplasia, cyanosis, and gross cardiomegaly. One Ebstein patient (2 months old) had undergone a Starnes operation elsewhere. Weight of the patients at operation ranged from 2.1 to 6.4 kg (mean 2.7 kg). Five patients had either anatomical (n = 3) or functional (n = 2) pulmonary atresia. Severe (4/4) tricuspid regurgitation was present in all except 1 (Starnes operation), and cardiothoracic ratio exceeded 0.85 in all patients. Echocardiography severity scores were >1.5 in 6 (grade 4/4) and 1.3 in 1 (grade 3/4). Repair consisted of tricuspid valve repair, reduction atrioplasty, relief of right ventricular outflow tract obstruction, partial closure of atrial septal defect, and correction of all associated cardiac defects. Technique of tricuspid valve repair evolved over time: 3 had Danielson-type repairs, 3 had DeVega-type repairs, and 2 had complex repairs. RESULTS: One patient died in hospital: a 2.1 kg patient with tricuspid dysplasia, anatomical pulmonary atresia, and hypoplastic pulmonary arteries. The other 7 patients are all in functional class I and in sinus rhythm. Although 3 patients had symptomatic tachyarrhythmias before surgery, no child has experienced SVT after discharge. At recent echocardiography 4 patients had mild tricuspid regurgitation, and 2 had mild-moderate (2/4) tricuspid regurgitation. Three patients are now 7 years old, 2 are almost 2 years old, and the remaining 2 patients are 1 year old. CONCLUSIONS: Surgical repair of the severely symptomatic neonate with Ebstein's anomaly is feasible and safe. The repair appears durable and with good medium-term outcome.

Comparison of open subxiphoid pericardial drainage with percutaneous catheter drainage for symptomatic pericardial effusion.

BACKGROUND: The optimal therapy for symptomatic pericardial effusions remains controversial. This paper compares outcomes after the two most commonly used techniques, percutaneous catheter drainage and operative subxiphoid pericardial drainage. METHODS: We performed a 5-year retrospective, single-institution study to analyze outcomes after either percutaneous catheter drainage or subxiphoid open pericardial drainage for symptomatic pericardial effusions. RESULTS: Symptomatic pericardial effusions in 246 patients were treated by open pericardiotomy and tube drainage (n = 150) or percutaneous catheter drainage (n = 96). Drainage duration, total drainage volume, and duration of follow-up (2.6 years) were similar in both groups. Effusions were classified malignant in 79 (32%) patients and benign in 167 (68%) patients. No direct procedural mortality occurred, but the hospital mortality was 16 patients (10.7%) in the open group and 22 (22.9%) in the percutaneous group (p = 0.01) The 5-year survival rate was 51% in the open group versus 45% in the percutaneous group, despite a greater percentage of the open group having a preoperative malignant diagnosis (35% versus 28%). Symptomatic effusions recurred in 16.5% of the percutaneous group compared with 4.6% in the open group (p = 0.002), and sclerosis did not appear to reduce recurrence rates (10.7% with sclerosis versus 15.6% without; p > 0.05). The diagnosis of malignancy was confirmed in 16 of 27 (59%) percutaneous procedures performed on patients with known malignancy. In the open group, cytologic and pathologic evaluation of the pericardial specimen revealed malignancy in 32 of 52 (62%) patients with known malignancy. CONCLUSIONS: Subxiphoid and percutaneous pericardial drainage of symptomatic pericardial effusions can be performed safely; however, death occurs from underlying disease. Open subxiphoid pericardial drainage with pericardial biopsy appears to decrease recurrence but does not improve diagnostic accuracy of malignancy over cytology alone.

Magnetic resonance imaging findings in asymptomatic volunteers and symptomatic patients with temporomandibular disorders.

Internal derangement has been suggested to be a cause of temporomandibular disorders. This study compared magnetic resonance imaging findings in 82 asymptomatic volunteers and 263 symptomatic patients. Disk displacement was observed in 33% of the asymptomatic volunteers and 84% of the symptomatic patients. The prevalence of trauma, headache, and other joint problems was more common in symptomatic patients. A history of general anesthesia and orthodontic treatment was not increased in the symptomatic population compared with asymptomatic volunteers. This study suggests that disk displacement is more common in symptomatic subjects.

Operationalizing DSM-IV criteria for PMDD: selecting symptomatic and asymptomatic cycles for research.

While diagnostic criteria for premenstrual syndromes (PMS) exist, studies rarely state how these criteria are operationally applied. We examined the consequences of application of different operational methods for DSM-IV criteria for premenstrual dysphoric disorder (PMDD) to individual cycles in women with PMS and controls. PMDD criteria require the presence of both certain types or numbers of symptoms (5/11 symptoms present premenstrually, at least one being one of four mood symptoms) and certain phenomenal characteristics (present premenstrually, absent postmenstrually, causing interference premenstrually). We identified individual cycles as symptomatic or asymptomatic by applying criteria that operationalized the required phenomenal elements of PMDD according to four severity thresholds: literal (i.e. present or absent), 30%, 50%, 70%. Data examined were Daily Rating Form symptom scores from two symptomatic menstrual cycles both in 25 women with PMS and 25 controls. Literal thresholds correctly identified 28% of symptomatic and 4% of asymptomatic cycles, compared with 86 and 70% identification with a 30% threshold, 60 and 86% with a 50% threshold, and 0 and 100% with a 70% threshold. An "optimal" combination of 30% thresholds for premenstrual symptomatology and premenstrual interference and a 50% threshold for postmenstrual symptomatology correctly identified 92% of symptomatic cycles in women with PMS and 72% of asymptomatic cycles in controls. Different criteria for cycle inclusion yield markedly different sample compositions. No single operational threshold of the phenomenal features maximizes selection of both symptomatic and asymptomatic cycles, largely consequent to the ubiquity of postmenstrual symptoms and premenstrual "interference" even in women without PMS. At the very least, the method for operationalizing DSM-IV criteria should be described in studies of PMDD.

Comparison of pathological and biological features of symptomatic and mammographically detected ductal carcinoma in situ of the breast.

To determine whether the ductal carcinoma in situ (DCIS) detected mammographically or presenting clinically is the same or differs, pathological and biological (c-erbB-2 and p53 detection) features of 79 cases of pure DCIS, 5 cases with microinvasion and 8 cases with 1 to 2 mm of invasion, all detected by mammography, have been compared with 59 cases of pure DCIS, 8 cases with microinvasion and 7 cases with 1 to 2 mm invasion, all of which presented clinically. Half of the mammographically detected group were smaller than 20 mm, and there was a higher incidence of these being low grade, whereas 30% of the symptomatic cases were smaller than 20 mm, and more of this group were larger than 50 mm. For the pure DCIS, there were less high-grade and more intermediate-grade cases in the mammographically detected group, although the incidence of low grade was similar between the two groups. There were more cases with a micropapillary pattern in the symptomatic group. C-erbB-2 protein was detected in 42% of the mammographically detected cases, whereas 59% of the symptomatic cases had c-erbB-2 reactivity. P53 detection was similar for both groups (33.0% and 37.0%). There were more symptomatic cases with invasion, and these were predominantly high grade, whereas the mammographically detected cases were both high and intermediate grade. Twelve of the 15 symptomatic cases with invasion expressed c-erbB-2, in comparison with 4 of the 13 mammographically detected cases, with half of the high-grade lesions in the latter group being negative. This study has shown that although there is overlap of pathological and biological features between DCIS presenting clinically and that detected mammographically, there can be differences in extent, grade, and invasion. The impact of this, however, can be determined only by clinical follow-up.

Symptomatic ureteropelvic junction obstruction in children in the era of prenatal sonography-is there a higher incidence of crossing vessels?

OBJECTIVES: To determine whether prenatal sonography and early detection and correction of ureteropelvic junction obstruction (UPJO) has changed the incidence of crossing vessels as the etiology of obstruction in older children presenting with symptomatic UPJO. METHODS: We reviewed the medical records of all children and adolescents who underwent pyeloplasty for symptomatic UPJO between 1986 and 1999, during the era of widespread use of prenatal sonography. Operative notes were used to determine which patients had obstruction due to lower pole crossing vessels. RESULTS: Thirty-eight patients were identified who underwent pyeloplasty for symptomatic UPJO. Lower pole vessels were identified in 22 (58%) of 38 patients (P <0.0001 compared with historical controls). All patients underwent dismembered pyeloplasty and remained asymptomatic after surgery, with renal scans demonstrating excellent drainage and preservation of function. CONCLUSIONS: Prenatal ultrasonography has increased the incidence of crossing vessels as the etiology of UPJO in young children and adolescents presenting with symptomatic UPJO compared with the historical incidence of 11% to 15%. This finding may impact treatment recommendations with respect to endourologic management of the obstruction in this patient population. Currently, we recommend open dismembered pyeloplasty for young children and adolescents presenting with symptomatic UPJO.

Ureteroscopy and holmium:YAG laser lithotripsy: an emerging definitive management strategy for symptomatic ureteral calculi in pregnancy.

OBJECTIVES: To review the results of holmium laser lithotripsy in a cohort of patients who presented with symptomatic urolithiasis in pregnancy. Symptomatic urolithiasis in pregnancy that does not respond to conservative measures has traditionally been managed with ureteral stent insertion or percutaneous nephrostomy. Holmium:yttrium-aluminum-garnet (YAG) laser lithotripsy using state-of-the-art ureteroscopes represents an emerging strategy for definitive stone management in pregnancy. METHODS: A retrospective analysis was conducted at two tertiary stone centers from January 1996 to August 2001 to identify pregnant patients who were treated with ureteroscopic holmium laser lithotripsy for symptomatic urolithiasis or encrusted stents. Eight patients with a total of 10 symptomatic ureteral calculi and two encrusted ureteral stents were treated. The mean gestational age at presentation was 22 weeks. The mean stone size was 8.1 mm. The stones were located in the proximal ureter/ureteropelvic junction (n = 3), midureter (n = 1), and distal ureter (n = 6). RESULTS: Complete stone fragmentation and/or removal of encrusted ureteral stents were achieved in all patients using the holmium:YAG laser. The overall procedural success rate was 91%. The overall stone-free rate was 89%. No obstetric or urologic complications were encountered. CONCLUSIONS: Ureteroscopy and holmium laser lithotripsy can be performed safely in all stages of pregnancy, providing definitive management of symptomatic ureteral calculi. The procedure can be done with minimal or no fluoroscopy and avoids the undesirable features of stents or nephrostomy tubes.

Patient satisfaction with finasteride in the treatment of symptomatic benign prostatic hyperplasia.

The type and magnitude of urinary symptoms, the behavioral adjustments necessitated by such symptoms, and the degree of patient satisfaction with treatment and current health were evaluated in 102 men with symptomatic benign prostatic hyperplasia (BPH) who had been receiving finasteride for 9 to 12 months. We also evaluated these variables in a group of 109 men who had undergone transurethral resection of the prostate (TURP) for symptomatic BPH 9 to 12 months before the study. A validated, patient-directed telephone questionnaire was used to solicit information. Men with BPH who continued to receive finasteride therapy for at least 9 months experienced considerable symptomatic relief during the first year of therapy, and reported a high degree of satisfaction with their urinary condition. Urinary symptoms either resolved or occurred only rarely in the majority of men treated with finasteride. Most of the BPH patients taking finasteride (78%) indicated that urinary symptoms did not restrict their participation in normal activities. Fifty-four percent of finasteride patients rated their current health as excellent or very good, and 87% indicated that their current condition represented an improvement over their pretreatment state. Responses in the men treated with TURP reinforced previous observations about the effectiveness of this treatment in men with symptomatic BPH. Thus in the appropriate patient group, finasteride represents an effective management option for symptomatic BPH.

Symptomatic cytomegalovirus infection in renal transplant recipients given either Minnesota antilymphoblast globulin (MALG) or OKT3 for rejection prophylaxis.

To compare the impact of using Minnesota antilymphoblast globulin (MALG) versus the monoclonal antibody, OKT3, on the development of symptomatic cytomegalovirus (CMV) infection, we reviewed a cohort of 130 cadaveric renal transplant recipients enrolled in a prospective comparison of MALG versus OKT3 for rejection prophylaxis. Among the 112 patients at risk for CMV, prophylactic MALG was associated with an increased risk of symptomatic infection (relative hazard [rh] = 3.31; 95% confidence interval CI], 1.50 to 7.30; P = 0.003). Transplantation of kidneys from CMV-seropositive donors into CMV-seronegative recipients (rh = 5.22; 95% CI, 2.34 to 11.63; P = 0.00004), first transplantation (rh = 4.76; 95% CI, 1.06 to 21.3; P = 0.039), and acute rejection therapy (rh = 2.03; 95% CI, 0.98 to 4.21; P = 0.055) were also associated with an increased risk. Prophylactic MALG followed by treatment with any agent for acute rejection was strongly correlated with symptomatic CMV infection (rh = 4.46; 95% CI, 3.71 to 5.21; P = 0.00006). Symptomatic CMV infection was not only more frequent, but more severe in recipients of prophylactic MALG, and more MALG recipients were treated with ganciclovir. There was no difference in rejection rate for the two rejection prophylaxis regimens (P = 0.625). Prophylactic OKT3 results in less risk of symptomatic CMV infection than prophylactic MALG in cadaveric renal transplant recipients who are seropositive for CMV or whose donors are seropositive for CMV.(ABSTRACT TRUNCATED AT 250 WORDS)

Diagnostic value of two reagent strips (Multistix 8 SG and Combur 2 LN) in cirrhotic patients with spontaneous bacterial peritonitis and symptomatic bacterascites.

OBJECTIVE: Spontaneous bacterial peritonitis is a life-threatening complication in patients with liver cirrhosis requiring a rapid diagnosis. We have tested two reagent strips, Multistix 8 SG and Combur 2 LN for bedside diagnosis of spontaneous bacterial peritonitis and symptomatic bacterascites, a variant of spontaneous bacterial peritonitis. METHODS: Responses of the two strips in colorimetric scale were compared with results given by cyto-bacteriological analysis of ascitic fluid. Results with positivity in grades 1 and 2 of colorimetric scale were analyzed. RESULTS: Four hundred and forty three paracentesis were performed in 116 patients including 46 samples of ascitic fluid with spontaneous bacterial peritonitis occurring in 25 patients and 20 samples of ascitic fluid with symptomatic bacterascites occurring in 17 patients. Forty two percent of spontaneous bacterial peritonitis were culture-negative neutrocytic ascites, gram-positive pathogens and enterobacteriaceae were responsible for 36% and 21% episodes of spontaneous bacterial peritonitis and 71% and 29% episodes of symptomatic bacterascites respectively. Fifty seven percent of spontaneous bacterial peritonitis had polymorphonuclear cell count<1000/mm3. For spontaneous bacterial peritonitis diagnosis, grade 1 positive Multistix and Combur tests had a sensitivity of 69.6% and 80.4% respectively, and a negative predictive value of 96% and 97.3%. Grade 2 positivity increased specificity to 98% and 99.2% and positive predictive value to 75% and 91% for the two strips respectively. Grade 1 positive tests had a sensitivity of 100% and 90% and a negative predictive value of 100% and 99.4% respectively for diagnosis of spontaneous bacterial peritonitis with polymorphonuclear count > 1000/mm3. For symptomatic bacterascites diagnosis, grade 1 positive tests had a sensitivity of 22.4% and 44.4% respectively and a negative predictive value of 96% and 97%. CONCLUSION: Although Combur had a higher sensitivity than Multistix for the diagnosis of spontaneous bacterial peritonitis, sensitivity of the two strips remains low with polymorphonuclear cell count<1000/mm3. Grade 2 positive Combur test had an acceptable positive predictive value. Sensitivity of both strips is insufficient for diagnosis of symptomatic bacterascites. Rapid cyto-bacteriological analysis of ascitic fluid remains necessary for diagnosis of these complications.

Symptomatic intravenous antipyretic therapy: efficacy of metamizol, diclofenac, and propacetamol.

Fever is a common symptom in cancer patients. The most frequent causes of fever are infections, malignancy itself, various medications, transfusions, and allergy. Although it is necessary to treat the cause of fever, if possible, symptomatic fever management is also important. Surprisingly, little attention is paid to this topic in the medical literature, despite the fact that it is a very frequent problem. In order to support symptomatic fever therapy, we wanted to study the patients' discomfort accompanying fever and the beneficial effects of the symptomatic fever management. To the best of our knowledge, there is an absence of studies in this area, despite the fever discomfort can be an important reason for the antipyretic treatment, mainly in cancer patients. In this non-randomized open label pilot study, three intravenous antipyretics were tested in five groups of patients: diclofenac (75 mg, brief intravenous [IV] infusion) vs. metamizol (2500 mg or 1000 mg, brief IV infusion) vs. propacetamol (2000 mg or 1000 mg, slow IV injection or brief IV infusion). The study included 254 febrile episodes mainly in hemato-oncological patients with axillary temperature at least 38 degrees C. The main study endpoints were: changes in axillary temperature, improvement in patient comfort, and number and nature of adverse events. To support justification for symptomatic fever management in febrile patients, we asked the first 45 study subjects to fill in a questionnaire concerning their opinions about fever, fever-associated discomfort, and relief upon antipyretic therapy. All study medications had a significant antipyretic effect. However, metamizol at the dose 2500 mg was considered as the most effective, while propacetamol at the dose 1000 mg showed the lowest antipyretic efficacy. Concerning tolerability and adverse events, there were significant differences among the treatment groups. Diclofenac and metamizol (both 2500 mg and 1000 mg) were tolerated at best. All tested antipyretics significantly improved comfort in febrile patients. Overall, 87% of patients declared improvement in their comfort after administration of antipyretics. Based on the results of the present study, the choice of the antipyretic drug should depend on the clinical status of patient, contraindications, and potential adverse events and risks of the selected agent. It is advisable to use proparacetamol at the higher dosage and to administer it as a brief IV infusion in order to avoid injection-related adverse events. The symptomatic antipyretic treatment in febrile cancer patients is supported by patients themselves and has a significant role in the complex supportive care. Discomfort of patients during fever episodes may be greater than previously thought.

Ultrasonographic detection of asymptomatic endometrial cancer in postmenopausal patients offers no prognostic advantage over symptomatic disease discovered by uterine bleeding.

The aim of this study was to investigate whether endometrial carcinoma (EC) screening by transvaginal sonography (TVS) has a prognostic advantage over symptomatic EC. In a retrospective study, 190 postmenopausal patients with symptomatic EC and 123 asymptomatic patients with suspicious endometrium detected by TVS were analysed regarding clinical, socio-economic and histopathological findings. Total bleeding time and the International Federation of Gynecology and Obstetrics (FIGO) tumour stage were evaluated with respect to their effect on survival. In 123 asymptomatic patients with suspicious endometrium, 16 (13%) EC, 61 (50%) polyps, 21 (17%) hyperplasias, 23 (19%) atrophias, 1 (0.8%) myoma and 1 (0.8%) metastasis were found. TVS findings in asymptomatic patients resulted in unnecessary operations, which were associated with considerable costs totalling at least 116256. Compared with screened asymptomatic patients, symptomatic patients were significantly (P<0.05) older, more frequently obese, and hypertensive, had a larger proportion of cases living in rural areas and visited their gynaecologists rarely. The bleeding time of symptomatic patients strongly correlated with the tumour stage (P<0.0001). Depending on the bleeding time, the 5-year disease-free survival and overall survival rates were 77% and 86% (no bleeding), 83% and 98% (<8 weeks), 74% and 90% (8-16 weeks), and 62% and 69% (>16 weeks), respectively. The corresponding tumour stage-related data for disease-free and overall survival were 100% (Ia; both rates), 87% and 95% (Ib), 66% and 93% (Ic), 63% and 78% (II) and 36% (III/IV; both rates), respectively. Postmenopausal vaginal bleeding represents an early symptom of EC, but it is not always perceived as problematic by the patients. There is no prognostic advantage for screened compared with symptomatic patients, who had bleeding of shorter than 8 weeks. Moreover, patients who are at a high risk for EC tend to avoid TVS screening. Finally, endometrial screening often results in unnecessary operations, which are associated with increased morbidity and costs.
