Splenic Abscess in an Adolescent due to Salmonella enterica Conservatively Treated with Ultrasound-Guided Fine-Needle Aspiration. Case Rep Pediatr 2023; 2023:8802760. [PMID: 36949862 PMCID: PMC10027457 DOI: 10.1155/2023/8802760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2022] [Revised: 02/13/2023] [Accepted: 02/16/2023] [Indexed: 03/14/2023] Open
Abstract
Background Splenic abscesses are rare and potentially fatal. Diagnosis is often delayed due to vague symptoms, and laboratory findings are varying and often nonspecific. Ultrasound and computed tomography have a high sensitivity in detecting splenic abscesses. Splenectomy was previously considered the gold standard for treatment, but in recent years, a shift has been seen towards a more conservative approach, i.e., ultrasound-guided aspiration or drainage in combination with adequate antibiotics in selected cases. Case Report. A previously healthy adolescent complained of left-sided chest pain, pain in the left clavicular region for three weeks, and recent fever. Ultrasound and computed tomography demonstrated an intrasplenic abscess. The patient was successfully treated with two percutaneous fine-needle punctures and adequate antibiotics for six weeks. Salmonella enterica serotype Poona was grown from the aspirate. At one-year follow-up, the patient remained healthy without signs of recurrence. Conclusion The present case report demonstrates that ultrasound-guided aspiration and subsequent treatment with antibiotics may be an effective alternative to splenectomy in patients with a splenic abscess.

Abstract
In Denmark, most cases of nephropathia epidemica (NE) occur on the island of Funen and are caused by the transmission of Puumala hantavirus to humans from the bank vole. This is a case report comprising four cases of NE occurring in close vicinity to Silkeborg, Jutland, where the disease is not usually seen. NE is characterised by increased vascular permeability, and patients present with flu-like symptoms progressing to acute kidney injury. When NE occurs in areas where it has not traditionally been endemic, awareness of the disease is important to ensure proper diagnosis.

Early normalization of reduced urea synthesis capacity after direct-acting antiviral therapy in hepatitis C cirrhosis. Am J Physiol Gastrointest Liver Physiol 319: G151-G156, 2020. First published June 29, 2020; doi:10.1152/ajpgi.00128.2020.-Effects of direct-acting antiviral (DAA) treatment of chronic hepatitis C (CHC) cirrhosis on metabolic liver function are unknown but important for prognosis. Ureagenesis is an essential metabolic liver function involved in whole body nitrogen homeostasis. We aimed to investigate the ureagenesis capacity before and immediately after DAA therapy and relate the findings to hepatic inflammation and structural changes. In an observational before-and-after intervention study, the ureagenesis capacity was quantified by functional hepatic nitrogen clearance (FHNC) in 9 CHC patients with cirrhosis and 10 healthy volunteers. Hepatic inflammation was evaluated by alanine aminotransferase (ALT) and the macrophage activation markers sCD163 and sMR. Structural changes were estimated as liver stiffness and by portal hypertension as the hepatic venous pressure gradient (HVPG). Before treatment, the FHNC in the patients was half of the controls [16.4 L/h (8.2-24.5) vs. 33.4 (29.2-37.6), P = 0.0004]; after successful DAA treatment, it normalized [28.4 (15.9-40.9), P = 0.008 vs. baseline]. DAA treatment normalized ALT (P < 0.0001) and decreased the elevated sCD163 from 5.6 mg/L (3.5-7.7) to 3.4 (2-0-4.8) (P < 0.001) and sMR from 0.35 mg/L (0.21-0.49) to 0.31 (0.17-0.45) (P < 0.01). Liver stiffness fell by 30% (P < 0.05) but remained over the cirrhosis threshold. HVPG was not affected (P = 0.59). DAA treatment restored the severely reduced ureagenesis capacity, along with amelioration of hepatic inflammation but without normalization of other cirrhosis characteristics. Our findings indicate that the anti-inflammatory effect of virus eradication independent of hepatic structural effects rapidly improves metabolic dysfunction. We suggest this effect to be an important early onset part of the expected clinical DAA treatment benefit.NEW & NOTEWORTHY Antiviral treatment of chronic hepatitis C restores the liver's reduced capacity to produce urea along with an improvement in liver inflammation without immediate effects on structural liver changes. The effect is suggested to be an important early onset part of the expected clinical treatment benefit.

Abstract
Erysipelas is a common skin infection involving the lymphatic vessels, which induces an oedema. This has a tendency of persisting after infection is treated. The lymphatic system plays an important role in the immune system, and the impaired lymph drainage leads to a state of local immune deficiency. This is essential to the pathogenesis of recurrent erysipelas, as each episode of erysipelas further damages the lymphatic system and increases the risk of a new infection. This vicious circle makes it important to treat both erysipelas and oedema appropriately to reduce recurrence and morbidity.

Abstract
OBJECTIVE In Denmark, pregnant women have been screened for hepatitis B virus (HBV) since 2005, and children born to HBV-infected mothers offered hepatitis B immunoglobulin at birth, vaccination against HBV at birth and after 1, 2 and 12 months. The purpose of this study was to determine the risk of vertical HBV transmission in children born to mothers with chronic HBV infection, to investigate the antibody response in the children and to investigate possible maternal predictive risk factors for HBV transmission. MATERIALS AND METHODS Through the Danish Database for Hepatitis B and C, we identified 589 HBV-infected women who had given birth to 686 children, of whom 370 children were born to 322 women referred to hospital. 132 (36%) children, born to 109 mothers, were included in the study; 128 children had blood samples tested for HBsAg, anti-HBc (total), anti-HBs and HBV-DNA and four children had saliva samples tested for anti-HBc. RESULTS We found vertical HBV transmission in Denmark to be 2.3% [95% CI: 0.5, 6.5], a high proportion of HBsAg-negative children with low levels of anti-HBs (18.4%) and a high proportion (15.2%) with resolved HBV infection. No maternal risk factor was statistically significantly associated with HBV vertical transmission. CONCLUSION In a HBV low prevalence setting as Denmark, despite a national vaccination program, vertical HBV transmission occurred in 2.3% of children born to HBV-infected mothers. In addition, a high proportion of the children had insufficient anti-HBs levels and a high proportion had serological signs of resolved HBV infection.

Rotavirus is frequent among adults hospitalised for acute gastroenteritis. DANISH MEDICAL JOURNAL 2017; 64:A5312. [PMID: 28007052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/06/2023]
Abstract
INTRODUCTION Rotavirus infection is the most common aetiology of acute gastroenteritis (AGE) among young children. In adults, diagnostics focus mainly on bacterial causes, though recent studies suggest that rotavirus is a frequent agent. The aim of this study was to examine the proportion of rotavirus in adults hospitalised with AGE and to identify possible predictors. METHODS During a 24-month period from 1 May 2010 adults (> 15 years) with AGE admitted to one of four hospitals in the Central Denmark Region were examined for rotavirus with VIKIA Rota-Adeno rapid test in addition to routine culture for bacterial pathogens. RESULTS A total of 265 adult patients were included. 9.4% tested positive for rotavirus. Enteropathogenic bacteria were found in 24.5% of the cases. In the majority of cases (62.3%), no pathogen was found. Overall, rotavirus was the second-most frequent pathogen, exceeded only by Campylobacter spp. Immunosuppression and a C-reactive protein (CRP) below 50 mg/l (0-8 mg/l) were associated with rotavirus. The seasonality of rotavirus differed markedly from that of bacterial gastroenteritis. CONCLUSION Rotavirus is the second-most frequently identified pathogen in adults hospitalised with AGE. Close contact to children or travel activity does not predict rotavirus gastroenteritis, but immunosuppression and a CRP below 50 mg/l do. The seasonality of rotavirus differs from that of bacterial gastroenteritis, making rotavirus the most frequently identified cause of AGE in adults admitted to hospital in the colder months. FUNDING The trial was funded by an unrestricted grant from Sanofi Pasteur MSD. TRIAL REGISTRATION not relevant.

Abstract
Intervertebral discitis is a rare disorder which is easily missed. It presents with non-specific symptoms such as irritability, abdominal pain, decreased appetite and limping. The infection parameters can be normal, and blood cultures are often negative. The pathogenesis is not established but infectious, and inflammatory aetiologies have been suggested. Diagnostic golden standard is magnetic resonance imaging. The treatment is immobilization, anti-inflammatory drugs and often antibiotics. Early treatment is important to reduce the risk of complications such as nerve damage and spine fusion.

Abstract
This is the first case report of recurrent invasive pneumococcal disease (IPD), specifically, due to serotype 12F. The patient described here was vaccinated with the 23-valent pneumococcal polysaccharide vaccine (PPV23) due to previous splenectomy, and an anti-pneumococcal IgG test concluded that she had responded sufficiently to vaccination. Still, she had a fulminate recurrent infection with PPV23 serotype 12F. We investigated the anti-pneumococcal IgG test, and it turned out that it is based on the geometric mean value of only 12 of the serotypes included in PPV23; 12F is none of them. The reason is that there are no titer cut-offs available for 11 of the PPV23 serotypes, including 12F, neither nationally nor internationally. Yet, this is not specified in the answer to the clinicians. This case illustrates the need for titer cut-offs for the remaining pneumococcal serotypes in available vaccines, in order to get a more accurate estimation of the vaccination coverage for the individual patient. Therefore, more research on this area is warranted, along with a discussion of whether the laboratory answers to the clinicians should be more detailed.

Abstract
We report a case of intestinal tuberculosis in a 42-year-old Danish woman with stomach pain, weight loss and diarrhoea for months suspective of Crohn's disease. She underwent hysterectomy where white, small nodules were found on the small intestine. Biopsies showed non-necrotizing granulomatous inflammation. Gastroscopy and colonoscopy were normal. Capsule endoscopy revealed small intestine ulcers and a stenosis. A CT scan of the abdomen confirmed stenosis and inflammation of terminal ileum. QuantiFERON-TB Gold Test was positive and Mycobacterium tuberculosis was detected in faeces cultures.

Abstract
BACKGROUND Long-term results after aortic value replacement for aortic stenosis can be correlated to a cardiac-related pre-operative risk profile. This predictability indicates that there is a common basis in subtle or overt structural abnormalities of left ventricular myocardium. METHODS AND RESULTS Forty-nine patients aged 24-82 (mean 61) years, with aortic stenosis had a full wall thickness transmural biopsy of the left ventricular antero-lateral free wall during aortic valve replacement. Echocardiography and radionuclide ventriculography were performed prior to, and 18 months (n = 41) after, the operation. Postoperative follow-up to a maximum of 7.7 years was 100% complete. Pre-operatively, all patients had an increase in both the left ventricular mass index (202 +/- 67 g.m-2) and the muscle cell diameter (41 +/- 8 microns); other morphological data included a muscle cell nucleus volume of 752 +/- 192 microns3, a muscle cell mass index of 163 +/- 54.m-2, and a fibrous tissue mass index of 39 +/- 16 g.m-2. Patients with a pre-operative episode of clinical left ventricular failure (n = 19) had significantly greater morphological variables than those without. Pre-operative ejection fraction and other measures of systolic function correlated inversely with the morphological data, except for the fibrous tissue mass index; diastolic function indices correlated inversely with all the morphological variables. At the 18-month re-study, the same general picture was noted, but with an underlying strengthening, especially of the muscle cell mass index. Overall, the mass index dropped to 152 +/- 51 g.m-2 (P < 0.0001), but in 17% of the patients it became normal; the mass index at 18 months was directly correlated to morphological variables. A high muscle cell nucleus volume was identified as an independent predictor of early and late mortality. CONCLUSIONS Abnormalities of the hypertrophied left ventricular muscle cell and the degree of muscle hypertrophy are, to some degree, underlying determinants of pre-operative symptomatology, pre- and postoperative ventricular function, and early and late mortality after valve replacement for aortic stenosis. Incomplete hypertrophy impaired results, was related to pre-operative myocardial structural abnormalities.

Abstract
In a prospective study, 99 consecutive patients with an operative indication due to severe aortic stenosis (AS) were put on a surgical waiting list. The waiting time to aortic valve replacement (AVR) averaged 6.3 months (0.5-19 months). There were 58 men and 41 women with a mean age of 61 years (21-82 years). The patients were divided into three groups: group 1 (N = 81) with an uneventful stay on the waiting list; group 2 (N = 11) with significant worsening of a prognostic index; and group 3 (N = 7) with patients who died during the waiting time. The waiting list death rate was 13.5%/patient-year compared with a post-AVR death rate of 4.9% patient-year (p < 0.05) with a mean post-AVR follow-up of 5.7 years. According to a prognostic index (Cox regression model) at inclusion, group 2 patients had a predicted 7-year post-AVR survival probability of 72%, but only of 61% according to their prognostic index immediately preoperatively; their observed 7-year post-AVR survival was 60%. Logistic regression analysis identified high age, short duration of symptoms, signs of severe hypertrophy and strain in the ECG, female gender, and deranged left ventricular diastolic function (related to severely increased left ventricular muscle mass) as independent predictors of prognostic worsening and death while on the waiting list. The predictive models did not allow sufficiently accurate identification of the patients at risk during the waiting period. The consequences of a surgical waiting period averaging 6 months are serious for AS patients. The death rate is high and a subgroup worsens its prognostic profile with a significantly reduced post-AVR long-term survival as the result.

Abstract
AIMS The aims of the study were to examine the prognostic value of pre-operative left ventricular systolic and diastolic function on early, and late mortality after valve replacement for aortic stenosis, and to identify possible underlying mechanisms. METHODS AND RESULTS Ninety-one prospectively recruited consecutive patients with a mean age of 61 years underwent valve replacement for aortic stenosis with concomitant coronary artery bypass grafting in 32 and a minimum postoperative observation period of 5.4 years. There were six early (< or = 30 days postoperatively) and 19 late deaths, and 18 deaths from specific causes (cardiac and prosthetic valve related). Early mortality occurred exclusively among patients with a combined subnormal left ventricular systolic function (subnormal ejection fraction or peak ejection rate, or supranormal time-to-peak ejection--duration of systole ratio) and a subnormal fast filling fraction. In Cox regression models on crude mortality and specific deaths, a subnormal ejection fraction and a fast filling fraction of < or = 45% were the only independent risk factors. Patients with none of these risk factors had normal sex- and age-specific survival, those with any one factor had an early, and those with both factors a massive early and a late excess mortality, with 5-year crude survival of 92%, 77%, and 50%, respectively (P < 0.0001). Systolic wall stress was without prognostic value. Further analyses indicated that impairment of left ventricular function occurred with increasing muscle mass over two phases: (1) diastolic dysfunction characterized by a pattern of severe relative concentric hypertrophy; (2) the addition of systolic dysfunction characterized by a more dilated, less concentric chamber geometry. Coronary artery disease seemed to provoke the latter development sooner. CONCLUSIONS Impaired systolic and diastolic left ventricular function, irrespective of afterload, were decisive independent pre-operative risk factors for early as well as late mortality after aortic valve replacement for aortic stenosis. The adverse influence of concentric hypertrophy was the main underlying mechanism. Operative intervention, before impairment of diastolic and systolic function, should be advocated.

Abstract
BACKGROUND The hemodynamic function of the St. Jude valve may change relative to changes in left ventricular function after aortic valve replacement for aortic stenosis. From theoretical reasons one may hypothesize that prosthetic valve hemodynamic function is related to left ventricular failure and mismatch between valve size and patient/ventricular chamber size. METHODS Forty patients aged 24 to 82 years who survived aortic valve replacement for aortic stenosis with a standard St. Jude disc valve (mean size, 23.5 mm; range, 19 to 29 mm) were followed up prospectively with Doppler echocardiography and radionuclide left ventriculography preoperatively and 9 days, 3 months, and 18 months after the operation with assessment of intravascular hemolysis at 18 months. Follow-up to a maximum of 7.4 years (mean, 6.3 years) was 100% complete. RESULTS Left ventricular muscle mass index decreased from 198 +/- 62 g.m-2 preoperatively to 153 +/- 53 g.m-2 at 18 months (p < 0.001), paralleled by a significant increase in left ventricular ejection fraction, peak ejection rate, and peak filling rate; only 18% of the patients had normal left ventricular muscle mass index and only 32% normal ventricular function (normal left ventricular ejection fraction, peak ejection rate, peak filling rate, early filling fraction, and late filling fraction during atrial contraction) at 18 months. Prosthetic valve peak Doppler gradient dropped from 20 +/- 6 mm Hg at 9 days to 17 +/- 5 mm Hg at 18 months (p < 0.05). Reduction of left ventricular muscle mass index was unrelated to peak gradient and size of the valve. Peak gradient at 18 months rose with valve orifice diameter of 17 mm or less (by 6 mm Hg), orifice diameter/body surface area of 9 mm.m-2 or less (by 5 mm Hg), left ventricular enddiastolic dimension (by 23 mm Hg per 10 mm increase), and impaired ventricular function (by 3 mm Hg). All but 2 patients (5%) had intravascular hemolysis; none had anemia. Two patients with moderate paravalvular leak had the highest serum lactic dehydrogenase levels; 4 patients with trivial leak had higher serum lactic dehydrogenase levels than those without leak. Serum lactic dehydrogenase levels rose with moderate paravalvular leak, impaired ventricular function, and valve orifice diameter. Six patients with trivial or moderate paravalvular leak had a cumulative 7-year freedom from bleeding and thromboembolism of 44% +/- 22% compared with 87% +/- 5% for those without leak (p < 0.05). CONCLUSIONS The peak gradient of the St. Jude aortic valve dropped marginally over the first 18 postoperative months in association with incomplete left ventricular hypertrophy regression and marginal improvement of ventricular function. Mismatch between valve size and ventricular cavity size or patient size and impaired function of a dilated ventricle significantly compromised the performance of the St. Jude valve. Probably explained by platelet destruction or activation, paravalvular leak was related to bleeding and thromboembolic complications.

Abstract
The complications resulting from different methods of translumbar aortography were evaluated by checking 1192 examinations performed with 1) a cannula, 2) a straight catheter, and 3) a curved catheter. The latter method was found to be far more safe than the other two. According to the complication rates found in the literature the curved catheter translumbar method is also safer than the transaxillar and comparable to transfemoral aortography by the Seldinger method.
