Atraumatic splenic rupture as first presentation of hairy cell leukaemia-a case report.

Atraumatic splenic rupture is a complex surgical pathology owing to its rarity, non-specificity of symptoms and gravity of possible outcomes. This case outlines the investigation and management of a patient with atraumatic splenic rupture secondary to undiagnosed hairy cell leukaemia. While the patient was initially managed conservatively, they went on to have a splenectomy owing to ongoing transfusion requirements. A review of the literature has also been performed and presented to highlight the potential causes of atraumatic splenic rupture and the various options for confirming diagnosis and definitive management.

Massive bleeding from an infected pseudoaneurysm in an arteriovenous graft that resulted in death: A case report.

We report an autopsy of a death due to a ruptured infected pseudoaneurysm; a man in his 70s was found dead with massive bleeding from the shunt of his right arm. Autopsy and pathological examination revealed that the cause of death was hemorrhagic shock due to rupture of an infected pseudoaneurysm. Ruptured aneurysms and pseudoaneurysm are a complication of dialysis, and death is rare because they are treated immediately on discovery. However, these ruptures often occur in non-medical facilities and could result in death if the patient does not have knowledge of first aid. Thus, patient education is important. Approximately only half of the deaths due to massive bleeding from a shunt are autopsied. In Japan, autopsies or partial autopsies are considered necessary to determine whether a bleeding was traumatic and to prevent medical errors from being overlooked.

Rupture Endometriomas Presenting as Acute Abdomen Infection in Hasty and Limited Resources Setting: A Pitfall Not to Miss - A Case Report.

Introduction: Abdominal pain is a diagnostic problem that requires immediate care and treatment for surgeons and gynecologists. The causes of abdominal pain in women of childbearing age range from benign and temporary to potentially life threatening. Rare etiologies such as spontaneous ruptured endometrioma are often not included in the radar of diagnosis due to their rarity and non-specific signs and symptoms in the patient. This case report aimed to show a resemblance between the clinical symptoms of acute abdomen in diffuse peritonitis due to hollow viscus perforation and spontaneous ruptured endometrioma. Case Description: A 42-year-old woman presented to our hospital with abdominal pain. She had a history of fever for two weeks. She came from a tropical rural area where typhoid fever is common. She was advised to undergo emergency laparotomy because of the suspicion of diffuse peritonitis due to a hollow viscus perforation due to typhoid infection. Because of acute abdominal pain, a vertical incision was made to explore her abdominal cavity, and chocolate-like fluid and ovarian cysts were found during surgery. The diagnosis was changed to diffuse peritonitis due to spontaneous rupture of the endometrioma bilaterally. Conclusion: This case suggests that the exact diagnosis and cause of abdominal pain varies. As the current gold standard for endometrioma is laparoscopy, surgeons must prepare a collaborative approach to the cause of the disease.

Abdominal pain is common and often requires prompt medical care. In women, it can have various causes, including rare ones, such as spontaneous ruptured endometrioma, which can be difficult to diagnose owing to its rarity and vague symptoms. We describe the case of a 42-year-old woman with abdominal pain and fever, initially suspected to have diffuse peritonitis due to typhoid infection. However, surgery revealed a ruptured endometrioma, highlighting the challenge of accurately diagnosing such conditions. This case emphasizes the need to consider the diverse diagnoses of abdominal pain and the importance of collaborative approaches among medical professionals to ensure accurate diagnosis and treatment.

A Comparison of Neonatal Outcomes Between Obese and Nonobese Women With Preterm Prelabor Rupture of Membranes.

Introduction Preterm prelabor rupture of membrane (PPROM) contributes to increasing rates of preterm birth, causing greater health risks for newborns. While the mechanisms driving PPROM are not well understood, one hypothesis is that it is due to systemic inflammation, which can be caused by obesity defined as a BMI [Formula: see text]30 kg/m2. The specific aim of the study was to compare neonatal outcomes after PPROM between patients who were obese vs not obese in early pregnancy at a tertiary medical center serving an Appalachian population. Methods An observational, descriptive retrospective review was conducted of the medical records of patients who were diagnosed with PPROM from January 2017 through December 2020. Patients with a single gestation at the time of PPROM without evidence of clinical infection requiring immediate delivery were included. Maternal characteristics, latency management, and birth outcomes were compared between obese ([Formula: see text]30 BMI) and non-obese (<30 BMI) patients. Results Of the 214 women in the study, 129 (60.3%) were obese pre-pregnancy and 85 (39.7%) were not. Most PPROM occurred between 32 and 36 weeks of gestation (145 patients, 67.8%), with 19.2% occurring at 26-31 weeks (41 patients), and 13.2% at <26 weeks of gestation (28 patients). Latency, defined as the days between PPROM and delivery, ranged from 0 to 80 days with a mean of 4.9 + 10.9 days. At least one day of latency was achieved for most patients (144/214; 67.3%). When outcomes were compared between obese and nonobese patients, the obese patients experienced significantly more complications (10.1% vs 2.4%; p=0.031), which were accompanied by greater neonatal morbidity 67 of 129 ((51.9%) vs 30 of 85 (35.3%); p=0.018). Obese women had greater odds that their newborns would experience neonatal morbidity than nonobese women (odds ratio, 1.98; 95% confidence interval, 1.1-3.5). Conclusion This study of Appalachian women found that pre-pregnancy BMI [Formula: see text]30 increased the risk of complications and neonatal morbidity after PPROM. To improve birth outcomes, healthcare workers and policymakers must work together to decrease rates of obesity in Appalachian women at or near childbearing age.

An Unusual Presentation of Acute Severe Mitral Regurgitation.

Mitral regurgitation (MR) results from retrograde blood flow from the left ventricle to the left atrium. Common etiologies of acute severe MR include papillary muscle rupture from myocardial infarction, leaflet perforation in infective endocarditis, chordal rupture (pop) in myxomatous valve disease, acute rheumatic fever with carditis, or functional MR due to cardiomyopathies, myocarditis or Takotsubo cardiomyopathy. Here, we present an unusual case of acute severe MR due to ruptured chordae tendineae likely secondary to degenerative valve disease. A 59-year-old male with a past medical history of hypertension and renal calculi was evaluated in the outpatient office for a urologic procedure. He was sent to the emergency room with left-sided chest pain, 6/10 in intensity, burning in nature, and non-radiating with no aggravating and relieving factors. He had nausea and vomiting for the past three days. He reported similar chest pain at rest and on exertion multiple times over the past year. He also had a chronic cough with no recent changes. His examination was unremarkable. Chest X-ray showed interstitial lung markings. Electrocardiography revealed an old right bundle branch block, but no ST/T-wave changes. He was admitted and treated for atypical pneumonia with ceftriaxone and azithromycin. The following morning, he complained of persistent chest pain 9/10 in intensity which improved with nitroglycerin. His examination revealed a new onset holosystolic murmur heard over the precordium. A two-dimensional echocardiogram showed a preserved ejection fraction of 55-60%, severe MR with eccentric jet, concerning for partially flail leaflet of the mitral valve. He was transferred to the university hospital for mitral valve replacement. Patients with acute rupture of chordae tendineae usually progress to severe mitral valve regurgitation. These patients usually present with pulmonary edema, signs of heart failure, and cardiogenic shock. Papillary muscle dysfunction, as well as partial or complete rupture of the mitral chordae can be detected as a new-onset holosystolic murmur and can be a crucial sign for early recognition. In our case, the patient developed a new holosystolic murmur on day two of admission which was recognized early, and prompt surgical intervention was performed.

Azithromycin Dosing and Preterm premature rupture of membranes Treatment (ADAPT): A randomized controlled Phase I trial.

BACKGROUND: Seven days of antibiotics are recommended in the setting of preterm premature rupture of membranes (PPROM) to promote latency. Azithromycin has generally replaced a seven-day course of erythromycin in current clinical practice. Azithromycin clears from plasma quickly and concentrates in local tissue which is why daily dosing is not always needed and local tissue, rather than plasma, concentrations are used to determine dosing. Based on limited pharmacokinetic studies in pregnancy, 1g one time dose of azithromycin may not maintain local (amniotic fluid) drug concentrations above minimum inhibitory concentrations (MIC50) for common genitourinary pathogens (50-500ng/ml). OBJECTIVE: We aim to compare the pharmacokinetics of one-time vs daily dosing of azithromycin in the setting of preterm pre-labor rupture of membranes (PPROM) STUDY DESIGN: This is a randomized clinical trial of singletons with PPROM randomized to 1gram oral azithromycin once or 500mg oral azithromycin daily x7 days. Primary outcome was amniotic fluid azithromycin concentrations over 8 days. Secondary outcomes included plasma azithromycin trough concentrations. Plasma was collected at time points 1-4hrs and 12-24hrs after first dose, and then every 24hrs through 8 days. Amniotic fluid was collected opportunistically throughout the day noninvasively with Always Flex-foam pads. We aimed to enroll 20 participants to achieve N=5 still pregnant through 8 days in each group. Continuous variables compared with Mann Whitney U test and relationship between azithromycin concentration and time assessed with linear regression. RESULTS: The study was halted after N=6 enrolled due to lagging enrollment, with 3 in each group. The mean gestational age of enrollment was 27.1±1.7weeks in the 1g group and 31.0±1.4 weeks in the 500mg daily group. One participant in each group had latency to delivery >7days. Regarding amniotic fluid azithromycin concentration, there was a difference in change in amniotic fluid azithromycin concentration over time between groups (p<0.001). Amniotic fluid concentration of azithromycin was relatively stable in the 1g once group (B=-0.07 (-0.44 - 0.31), p=0.71), in contrast, amniotic fluid concentration (ng/ml) increased over time (hours) in the 500mg daily group (B=1.3 (0.7 - 1.9), p<0.001). By ≥96hours median amniotic fluid levels of azithromycin were lower in the 1g once dosing group (median 11[7-56]) compared to 500mg daily (median 46 [23-196]), with a median difference -27 (-154 to -1), p=0.03. In plasma, there was higher azithromycin concentration during the first 24hrs with 1g once vs 500mg daily (median difference 637ng/ml (101-1547), p=0.01), however by ≥96hrs plasma azithromycin declined and was virtually undetectable in the 1g once group, while trough plasma levels in the 500mg remained elevated (median difference -207ng/ml (-271 to -155), p=0.03). CONCLUSION: 500mg daily dosing of azithromycin maintains higher amniotic fluid concentrations, and more consistently greater than common MICs, over eight days compared to 1g once in the setting of PPROM.

Tissue characteristics of residual lesion in patients with acute coronary syndrome caused by plaque rupture versus plaque erosion: a single-center, retrospective, observational study.

Patients with acute coronary syndrome (ACS), frequently caused by plaque rupture (PR), often have vulnerable plaques in residual lesions as well as in culprit lesions. However, whether this occurs in patients with plaque erosion (PE) as well is unknown. We retrospectively analyzed the data of 88 patients with ACS who underwent both optimal coherence tomography (OCT) and intravascular ultrasound (IVUS). Based on plaque morphology of the culprit lesions identified using OCT, patients were classified into PE (n=23) and PR (n=35) groups. The tissue characteristics of residual lesions evaluated using integrated backscatter IVUS were compared between both groups after percutaneous coronary intervention. The PE group had a significantly lower percent lipid volume and a higher percent fibrous volume than the PR group (35.0±17.8% vs 49.2±13.4%, p<0.001; 63.2±17.1% vs 50.3±13.1%, p=0.002, respectively). Receiver operating characteristic curve analysis revealed that percent lipid volume in the residual lesions was a significant discriminant factor in estimating the plaque morphology of the culprit lesion (optimal cut-off value, <43.5%; sensitivity and specificity values were 73.9% and 68.6%, respectively). In conclusion, patients with PE had a significantly lower percent lipid volume and a significantly higher percent fibrous volume in the residual lesions than those with PR, suggesting that the nature of coronary plaques in patients with PE is different from that of those with PR.

Presumed renal arterial aneurysm in a cat.

A 3-year-old cat was presented for an abdominal ultrasound examination with apathy and anemia. The US revealed the enlargement of the left kidney with a hypoechoic subcapsular thickening. An abnormal, tortuous vessel was visible in the medulla with arterial flow on pulsed-wave Doppler examination. The CT examination confirmed the ultrasound findings and a presumptive diagnosis of the intraparenchymal renal aneurysm was made. Four days later, the cat presented again with a worsening of its condition. The US features were suggestive for that of an aneurysm rupture.

Partial coil embolization before surgical clipping of ruptured intracranial aneurysms.

OBJECTIVE: Intraoperative rupture (IOR) is the most common adverse event encountered during surgical clip obliteration of ruptured intracranial aneurysms. Besides increasing surgeon experience and early proximal control, no methods exist to decrease IOR risk. Thus, our objective was to assess if partial endovascular coil embolization to protect the aneurysm before clipping decreases IOR. METHODS: We conducted a retrospective analysis of patients with ruptured intracranial aneurysms that were treated with surgical clipping at two tertiary academic centers. We compared patient characteristics and outcomes of those who underwent partial endovascular coil embolization to protect the aneurysm before clipping to those who did not. The primary outcome was IOR. Secondary outcomes were inpatient mortality and discharge destination. RESULTS: We analyzed 100 patients. Partial endovascular aneurysm protection was performed in 27 patients. Age, sex, subarachnoid hemorrhage severity, and aneurysm location were similar between the partially-embolized and non-embolized groups. The median size of the partially-embolized aneurysms was larger (7.0 mm [interquartile range 5.95-8.7] vs. 4.6 mm [3.3-6.0]; P < 0.001). During surgical clipping, IOR occurred less frequently in the partially-embolized aneurysms than non-embolized aneurysms (2/27, 7.4%, vs. 30/73, 41%; P = 0.001). Inpatient mortality was 14.8% (4/27) in patients with partially-embolized aneurysms and 28.8% (21/73) in patients without embolization (P = 0.20). Discharge to home or inpatient rehabilitation was 74.0% in patients with partially-embolized aneurysms and 56.2% in patients without embolization (P = 0.11). A complication from partial embolization occurred in 2/27 (7.4%) patients. CONCLUSIONS: Preoperative partial endovascular coil embolization of ruptured aneurysms is associated with a reduced frequency of IOR during definitive treatment with surgical clip obliteration. These results and the impact of preoperative partial endovascular coil embolization on functional outcomes should be confirmed with a randomized trial.

Maternal and perinatal infectious morbidity in term prelabor rupture of membrane according to two induction of labor protocols.

PURPOSE: The optimal labor-induction protocol in women with prelabor rupture of membranes (PROM) is unknown. Whether the management of women with a previous cesarean delivery (CD) with PROM is different remains controversial. We investigated maternal and perinatal outcomes according to two induction protocols of 24 h vs. 12 h. METHODS: In July 2021, our protocol of induction of labor in term-PROM was extended from 12 h to 24 h post-PROM. We compared obstetrical and neonatal outcomes before and after the change. A subgroup analysis of women with previous CD was performed. Results were compared using a univariate analysis. A multivariable model was described to predict neonatal intensive care unit admission (NICU) and clinical chorioamnionitis. RESULTS: The 24 h and 12 h ROM-to-induction protocol groups included 962 and 802 women, respectively. In the 24 h group, a higher proportion of women labored spontaneously (p < 0.001), the rate of chorioamnionitis was higher (p = 0.017), and the CD rate was similar. Admission to the NICU (p = 0.012), antibiotic administration (p = 0.003), and respiratory distress (p = 0.002) were also greater in the 24 h induction group. Among women with a history of CD (n = 143), the need for oxytocin (p = 0.003) and delivery by CD (p = 0.016) were lower in the 24 vs. 12 h group. CONCLUSION: Our results advocate shared decision-making in the expectant management of term-PROM. Women should be informed of the lower chance for induction and the higher risk of infections and neonatal complications with a 24-h induction approach. Longer expectant management in women with a previous CD resulted in significantly lower induction and CD rates.

Clinical comparative study of laparoscopic partial splenectomy and open partial splenectomy.

Introduction: The aim of the article was too investigate and compare the feasibility, safety, and early postoperative recovery associated with laparoscopic partial splenectomy (LPS) and open partial splenectomy (OPS) in patients with benign splenic tumours and traumatic splenic rupture. Material and methods: A retrospective analysis was conducted on clinical data from 110 patients undergoing splenic resection at our hospital between March 2019 and May 2022. Among them, 35 patients underwent OPS, 25 underwent LPS for traumatic splenic rupture, while 50 patients with benign splenic tumours underwent either OPS (n = 20) or LPS (n = 30). Preoperative, intraoperative, and postoperative data were collected and compared. Statistical analysis was conducted using SPSS software. Results: There was no significant difference in the general data between the 2 groups of patients with benign splenic tumours and those with splenic trauma. Among patients with traumatic splenic rupture, the OPS group had a shorter operation time (p < 0.05). Regardless of whether they had traumatic splenic rupture or benign splenic tumours, the LPS group required less postoperative analgesia and had a shorter defecation recovery time (p < 0.05). Additionally, the LPS group displayed lower white blood cell count, white blood cell/lymphocyte ratio (WLR), neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), C-reactive protein (CRP), calcitonin (PCT), and interleukin-6 (IL-6) than the OPS group on the first and third days post-surgery (p < 0.05). Conclusions: In comparison to OPS, LPS presents significant advantages, including minimal surgical trauma, a reduced early postoperative inflammatory response, milder wound pain, and a faster recovery of gastrointestinal function.

Achilles tendon complications of fluoroquinolone treatment: a molecule-stratified systematic review and meta-analysis.

Purpose: The association between fluoroquinolone intake and Achilles tendinopathy (AT) or Achilles tendon rupture (ATR) is widely documented. However, it is not clear whether different molecules have the same effect on these complications. The purpose of this study was to document Achilles tendon complications for the most prescribed fluoroquinolones molecules. Methods: A literature search was performed on Pubmed, Cochrane, Embase, and Web of Science databases up to April 2023. Inclusion criteria: studies of any level of evidence, written in English, documenting the prevalence of AT/ATR after fluoroquinolone consumption and stratifying the results for each type of molecule. The Downs and Black's 'Checklist for Measuring Quality' was used to evaluate the risk of bias. Results: Twelve studies investigating 439,299 patients were included (59.7% women, 40.3% men, mean age: 53.0 ± 15.6 years). The expected risk of AT/ATR was 0.17% (95% CI: 0.15-0.19, standard error (s.e.): 0.24) for levofloxacin, 0.17% (95% CI: 0.16-0.19, s.e.: 0.20) for ciprofloxacin, 1.40% (95% CI: 0.88-2.03, s.e.: 2.51) for ofloxacin, and 0.31% (95% CI: 0.23-0.40, s.e.: 0.77) for the other molecules. The comparison between groups documented a significantly higher AT/ATR rate in the ofloxacin group (P < 0.0001 for each comparison). Levofloxacin and ciprofloxacin showed the same risk (P = n.s.). The included studies showed an overall good quality. Conclusion: Ofloxacin demonstrated a significantly higher rate of AT/ATR complications in the adult population, while levofloxacin and ciprofloxacin showed a safer profile compared to all the other molecules. More data are needed to identify other patient and treatment-related factors influencing the risk of musculoskeletal complications.

Uroperitoneum as an Atypical Source of Ascites: A Case Report.

Uroperitoneum secondary to spontaneous bladder rupture is a rare cause of ascites associated with significant morbidity and mortality. It can be difficult to detect and is often initially mistaken for other, more common etiologies. We present the case of a 56-year-old female with a history of cervical cancer treated with chemotherapy and radiation, radiation proctitis, and diabetes mellitus who presented with subacute onset abdominal pain and distension, urinary retention, and nausea. She had been diagnosed with cervical squamous cell cancer 12 years prior to presentation and was successfully treated with two months of chemotherapy and radiation, and a presumed recurrence five years later was treated to remission with chemotherapy. The golden-yellow appearance of her ascitic fluid during diagnostic paracentesis raised suspicion for urinary ascites that was confirmed by an elevated ascites-to-serum creatinine ratio and computed tomography (CT) cystography. Subsequent CT cystogram demonstrated leakage of contrast from the bladder with a 0.5 cm irregularity noted at the bladder dome, potentially representing the site of extravasation. A Foley catheter was placed at the time of admission with an immediate output of 1 L of fluid. Subsequently, her abdominal distension significantly improved, and her creatinine began to downtrend. Gynecologic oncology and urology were consulted and determined that she was not a candidate for surgical intervention given the significance of her bladder scarring. Positron emission tomography (PET)/CT was performed and revealed no active cancer. At the time of discharge, she had no episodes of emesis. Additionally, her creatinine had fallen to 1.0 mg/dl. She was discharged with a Foley catheter with plans to follow up with outpatient urology. While relatively uncommon, uroperitoneum should be suspected in patients presenting with new-onset ascites who have risk factors for spontaneous bladder rupture such as pelvic irradiation. Uroperitoneum has a significant rate of mortality and morbidity. Ascites urea and creatinine studies, followed by a CT cystogram if these studies are abnormal, should be performed in any patient with risk factors for uroperitoneum. Patients should be managed with the placement of a Foley catheter and urology consultation for surgical evaluation.

Designing Plastrons for Underwater Bubble Capture: From Model Microstructures to Stochastic Nanostructures.

Bubbles and foams are often removed via chemical defoamers and/or mechanical agitation. Designing surfaces that promote chemical-free and energy-passive bubble capture is desirable for numerous industrial processes, including mineral flotation, wastewater treatment, and electrolysis. When immersed, super-liquid-repellent surfaces form plastrons, which are textured solid topographies with interconnected gas domains. Plastrons exhibit the remarkable ability of capturing bubbles through coalescence. However, the two-step mechanics of plastron-induced bubble coalescence, namely, rupture (initiation and location) and subsequent absorption (propagation and drainage) are not well understood. Here, the influence of 1) topographical feature size and 2) gas fraction on bubble capture dynamics is investigated. Smaller feature sizes accelerate rupture while larger gas fractions markedly improve absorption. Rupture is initiated solely on solid domains and is more probable near the edges of solid features. Yet, rupture time becomes longer as solid fraction increases. This counterintuitive behavior represents unexpected complexities. Upon rupture, the bubble's moving liquid-solid contact line influences its absorption rate and equilibrium state. These findings show the importance of rationally minimizing surface feature sizes and contact line interactions for rapid bubble rupture and absorption. This work provides key design principles for plastron-induced bubble coalescence, inspiring future development of industrially-relevant surfaces for underwater bubble capture.

[Spontaneous rupture of the anterior lens capsule in Alport syndrome (case study)]. / Samoproizvol'noe vskrytie perednei kapsuly khrustalika pri sindrome Al'porta (klinicheskoe nablyudenie).

Alport syndrome is a hereditary disease characterized by glomerulopathy, manifested by hematuria and/or proteinuria, progressive decline in renal function, often combined with hearing and vision pathology. This article presents a clinical case of spontaneous opening of the anterior lens capsule in a patient with Alport syndrome, accompanied by uveitis and ophthalmic hypertension, and describes the features of the surgical aid and the postoperative period.

Bladder rupture secondary to bladder tumors: A gateway to peritoneal carcinoma ?

We report a case of spontaneous bladder rupture due to bladder carcinoma. A 62-year-old man presented to the emergency department with acute urine retention; two days later, the patient presented with abdominal distension and a large intraperitoneal effusion on CT scan, as well as a breccia in the bladder. Exploratory laparotomy confirmed a definitive diagnosis: bladder rupture due to bladder carcinoma. He underwent radical cystectomy. Surgery is recommended to treat carcinomatous bladder rupture. Rapid diagnosis is essential to optimize patient outcomes. The possibility of spontaneous bladder rupture should not be overlooked as a differential diagnosis in cases of acute abdomen.

Maternal Morbidity following Trial of Labor after Cesarean in Women Experiencing Antepartum Fetal Death.

This study aims to investigate whether trial of labor after cesarean delivery (TOLAC) in women with antepartum fetal death, is associated with an elevated risk of maternal morbidity. A retrospective multicenter. TOLAC of singleton pregnancies following a single low-segment incision were included. Maternal adverse outcomes were compared between women with antepartum fetal death and women with a viable fetus. Controls were matched with cases in a 1:4 ratio based on their previous vaginal births and induction of labor rates. Univariate analysis was followed by multiple logistic regression modeling. During the study period, 181 women experienced antepartum fetal death and were matched with 724 women with viable fetuses. Univariate analysis revealed that women with antepartum fetal death had significantly lower rates of TOLAC failure (4.4% vs. 25.1%, p < 0.01), but similar rates of composite adverse maternal outcomes (6.1% vs. 8.0%, p = 0.38) and uterine rupture (0.6% vs. 0.3%, p = 0.56). Multivariable analyses controlling for confounders showed that an antepartum fetal death vs. live birth isn't associated with the composite adverse maternal outcomes (aOR 0.96, 95% CI 0.21-4.44, p = 0.95). TOLAC in women with antepartum fetal death is not associated with an increased risk of adverse maternal outcomes while showing high rates of successful vaginal birth after cesarean (VBAC).

Angiotensin converting enzyme inhibitor and coenzyme Q10 as adjunctive treatment for patients with ventricular septal rupture following late onset myocardial infarction: a case report.

Ventricular Septal Rupture (VSR) is a rare complication of acute myocardial infarction and has a high mortality rate. Surgery is the definitive treatment. However, in hospitals with limited facilities, treating acute myocardial infarction patients with ventricular septal rupture, is challenging. A 74-year-old woman came to the emergency room of Dr. Koesma General Hospital, Tuban, East Java in December, 2019 with late-onset Acute Myocardial Infarction. On the following day, a new holosystolic murmur was heard in the left lower sternal border with palpable thrill. Transthoracic echocardiography showed VSR with severe pulmonary hypertension. This was followed by a drop in the blood pressure to 80/50 mmHg. The blood pressure was dependent on vasopressors until lisinopril and coenzyme Q10 were introduced. After 3 months, the haemodynamics of the patient were stable. This proved that the use of angiotensin-converting enzyme and coenzyme Q10 promotes more energy production, enables tissue healing and leads to balanced remodelling to increase the survival rate in cases of non-surgical treatment.

Antibiofilm effect of biogenic silver nanoparticle alone and combined with polymyxin B against carbapenem-resistant Acinetobacter baumannii.

Acinetobacter baumannii is a bacteria associated with nosocomial infections and outbreaks, difficult to control due to its antibiotic resistance, ability to survive in adverse conditions, and biofilm formation adhering to biotic and abiotic surfaces. Therefore, this study aimed to evaluate the antibiofilm activity of biogenic silver nanoparticle (Bio-AgNP) and polymyxin B alone and combined in biofilms formed by isolates of carbapenem-resistant A. baumannii (CR-Ab). In the biofilm formation inhibition assay, CR-Ab strains were exposed to different concentrations of the treatments before inducing biofilm formation, to determine the ability to inhibit/prevent bacterial biofilm formation. While in the biofilm rupture assay, the bacterial biofilm formation step was previously carried out and the adhered cells were exposed to different concentrations of the treatments to evaluate their ability to destroy the bacterial biofilm formed. All CR-Ab isolates and ATCC® 19606™ used in this study are strong biofilm formers. The antibiofilm activity of Bio-AgNP and polymyxin B against CR-Ab and ATCC® 19606™ demonstrated inhibitory and biofilm-disrupting activity. When used in combination, Bio-AgNP and polymyxin B inhibited 4.9-100% of biofilm formation in the CR-Ab isolates and ATCC® 19606™. Meanwhile, when Bio-AgNP and polymyxin B were combined, disruption of 6.8-77.8% of biofilm formed was observed. Thus, antibiofilm activity against CR-Ab was demonstrated when Bio-AgNP was used alone or in combination with polymyxin B, emerging as an alternative in the control of CR-Ab strains.

Characterization of Maximum Wall Shear Stress Points in Unruptured Cerebral Aneurysms Using Four-dimensional Flow Magnetic Resonance Imaging.

BACKGROUND: Maximum wall shear stress (maxWSS) points of unruptured cerebral aneurysms (UCAs) may cause wall remodeling leading to rupture. We characterized maxWSS points and their inherent intra-aneurysmal flow structures in a sizable cohort of saccular UCAs using four-dimensional (4D) flow magnetic resonance imaging (MRI). METHODS: After contrast administration, 50 saccular UCAs were subjected to 4D flow MRI using a 1.5 T MRI scanner. Post-processing of obtained data was performed using commercially available software. The maxWSS points and maxWSS values were evaluated. The maxWSS values were statistically compared between aneurysm groups. RESULTS: The maxWSS point was located on the aneurysm apex in 9 (18.0%), body in 2 (4.0%), and neck in 39 (78.0%) UCAs. The inherent intra-aneurysmal flow structure of the maxWSS point was an inflow zone in 34 (68.0%) UCAs, an inflow jet in 8 (16.0%), and an impingement zone in 8 (16.0%). The maxWSS point on the neck had significantly higher maxWSS values than those points on the other wall areas (P = 0.008). The maxWSS values of the maxWSS points on the apex and on the impingement zone were not significantly different compared with those of the other maxWSS points. CONCLUSION: The maxWSS points existed preferentially on the aneurysmal neck adjacent to the inflow zone with higher maxWSS values. The maxWSS points existed occasionally on the aneurysmal apex adjacent to the impingement zone. 4D flow MRI may be helpful to discriminate saccular UCAs with higher-risk maxWSS points that can cause wall remodeling leading to rupture.
