Case series

Gallbladder cancer (GBC) is a rare and highly aggressive malignancy, often characterized by nonspecific clinical presentations and late diagnosis, which contribute to its poor prognosis. It is commonly detected at advanced stages, leading to low survival rates. Surgical resection is the primary treatment, with the extent of surgery depending on the T stage of the cancer. In advanced cases, surgery is only considered if it can potentially be curative. Despite various treatment approaches for advanced GBC, survival outcomes remain poor...

OBJECTIVES: The aim of this study is to audit 7 years of data with a 3 year follow up from a high-volume stone centre performing extracorporeal shock wave lithotripsy (ESWL) to evaluate efficacy in stone clearance compared to existing knowledge and understand reasons for this performance. METHODS: Patients who received ESWL treatment for renal or proximal ureteric stones at a single centre between January 2012 and January 2019 (to allow minimum 3 year follow up) were retrieved...

INTRODUCTION: Congenital Generalized Lipodystrophy (CGL) is a rare autosomal recessive disease caused by mutations in genes responsible for the formation and development of adipocytes. Bone abnormalities are described. However, there is a scarcity of data. OBJECTIVE: To describe bone characteristics in a large CGL1 and 2 case series. METHODS: Cross-sectional study that assessed bone radiological features of CGL patients of a reference hospital in Fortaleza (CE), Brazil...

INTRODUCTION: Treatment for recurrent ovarian clear cell carcinoma (OCCC) is clinically challenging as response rates to traditional chemotherapy are low, and recurrence rates are high. Immunotherapy has shown promise for this ovarian cancer (OC) subtype, and tumor molecular testing allows for the identification of a patient population that might benefit most from this treatment. We describe the clinical course and somatic genomic testing of 4 patients who received pembrolizumab for recurrent OCCC concurrent with a combination of bevacizumab and/or cyclophosphamide...

BACKGROUND: Obstructed labor leading to a vesicovaginal fistula remains a devastating outcome of childbirth in low-resource countries. Women with an irreparable vesicovaginal fistula may be candidates for a urinary diversion, such as the Mainz II modified ureterosigmoidostomy procedure. Previous reviews state that the procedure should be considered in low-resource countries. However, given the limited duration of postoperative follow-up, these studies do not adequately represent the long-term morbidity and mortality that is likely associated with this procedure...

Extracorporeal membrane oxygenation (ECMO) has become a salvage therapy for patients with severe acute respiratory distress syndrome (ARDS). The management of orthopaedic trauma in ECMO-supported patients with ARDS remains an evolving area of interest. Orthopaedic injuries are often temporized with external fixators, skeletal traction, or splints due to hemodynamic instability as well as concerns of exacerbating underlying pulmonary injury. However, patients requiring ECMO support do not rely on their pulmonary system for oxygenation, the need for delayed fixation may not apply...

PURPOSE: The aim of this study is to describe the novel epidemiological and clinical characteristics of influenza A-induced severe pneumonia occurring after the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and to further assess its potential risk factors for mortality. METHODS: We retrospectively studied the consecutive case series of 30 patients with confirmed influenza A-induced severe pneumonia treated in the intensive care unit at Dazhou Central Hospital in Sichuan, China, from March 1 to April 30, 2023...

BACKGROUND: Cutaneous neoplastic disorders are often observed in small mammal pets, such as dogs, regardless of their gender. AIM: An important objective of this work was to give a full account of the clinical, pathological, and immune-histochemical features of several skin tumors in dogs. METHODS: This study was a case series in the hospital clinic, Faculty of Veterinary Medicine, Zagazig University, Egypt. Twenty-five dogs (14 males and 11 females) were examined clinically during the period from March 2022 to October 2023...

This study aimed to identify opportunistic infections among human immunodeficiency virus (HIV) infected patients in Turkey. Therefore, we conducted a systematic literature review of the studies published up to October 1, 2022, in the Pubmed, Web of Science (WoS), and ULAKBİM TR Dizin databases. We searched for medical subject headings (MeSH) terms of (HIV) OR (AIDS) OR (human immunodeficiency virus) AND (opportunistic infections) AND (Turkey). Fifty-five studies in Pubmed, 68 in WoS, and 212 in ULAKBİM TR Dizin were listed with these keywords...

PURPOSE: To present a reproducible method to calculate the toricity needed at the intraocular lens (IOL) plane with toric phakic IOLs (ICL, Staar Surgical) and compare its results with those obtained with the online calculator provided by the manufacturer. DESIGN: Retrospective case series. SETTING: Private practice, Buenos Aires, Argentina. METHODS: The formula originally described by Holladay to calculate the IOL power in phakic eyes was used to calculate the required spherical power along the less refractive meridian and along the more refractive meridian...

BACKGROUND: Postnasal drip (PND) syndrome is a prevalent complaint encountered in otolaryngology practices. PND may be refractory to medical therapy, and surgical treatments are complicated by side effects. OBJECTIVE: While posterior nasal nerve (PNN) ablation has demonstrated efficacy for chronic rhinitis overall, we sought to examine the effect of PNN ablation for patients with PND as their primary complaint. METHODS: This is a retrospective case series study of 40 chronic rhinitis (CR) patients with a primary complaint of PND...

BACKGROUND: Malaria remains one the leading communicable causes of death. Approximately half of the world's population is considered at risk of infection, predominantly in African and South Asian countries. Although malaria is preventable, heterogeneity in sociodemographic and environmental risk factors over time and across diverse geographical and climatological regions make outbreak prediction challenging. Data-driven approaches accounting for spatiotemporal variability could offer potential for location-specific early warning tools for malaria...

Liquid state entropy formulas based on configurational probability distributions are examined for Lennard-Jones fluids across a range temperatures and densities. These formulas are based on expansions of the entropy in a series of n-body distribution functions. We focus on two special cases. One, which we term the "perfect gas" series, starts with the entropy of an ideal gas; the other, which we term the "dense liquid" series, removes a many-body contribution from the ideal gas entropy and reallocates it among the subsequent n-body terms...

The tendency of materials to order in triboelectric series has prompted suggestions that contact electrification might have a single, unified underlying description. However, the possibility of "triboelectric cycles," i.e., series that loop back onto themselves, is seemingly at odds with such a coherent description. In this work, we propose that if multiple charge carrying species are at play, both triboelectric series and cycles are possible. We show how series arise naturally if only a single charge carrier species is involved and if the driving mechanism is approach toward thermodynamic equilibrium, and simultaneously, that cycles are forbidden under such conditions...

BACKGROUND: Generalized pustular psoriasis (GPP) is a rare, potentially life-threatening skin disease often requiring long-term therapy. We aimed to evaluate the use of Interleukin (IL)-17A inhibitors (secukinumab and ixekizumab) in GPP patients over 96 weeks. METHODS: We retrospectively analyzed a case series of 18 patients with GPP who received secukinumab (n = 13) and ixekizumab (n = 5) therapy with a 96-week follow-up period. The primary effectiveness analysis included determining the percentage of patients who achieved ≥90% or 100% improvement in the Generalized Pustular Psoriasis Area and Severity Index (GPPASI) score...

Anomalous aortic origin of the left coronary artery (AAOLCA) confers high risk for sudden cardiac arrest (SCA). This series aims to describe consecutive admissions with interarterial AAOLCA presenting with SCA and distinct clinical trajectories. An eight-year-old boy collapsed at school and received 10-min of cardiopulmonary resuscitation (CPR) and defibrillation prior to return of spontaneous circulation. He had no end-organ dysfunction and underwent uneventful coronary unroofing. In contrast, a 14-year-old boy presented with collapse while jogging...

BACKGROUND: There is insufficient information regarding the bleeding sites and surgical strategies of cardiac tamponade during catheter ablation for atrial fibrillation (AF). CASE PRESENTATION: Of the five patients with cardiac tamponade, three required surgical intervention and two required pericardiocentesis. In the first case of three cardiac tamponades requiring surgical intervention, considering that the peripheral route was used, the catecholamines did not reach the heart, and due to unstable vital signs, venoarterial extracorporeal membrane oxygenation (VA-ECMO) was inserted...

BACKGROUND: The metabolic benefits of bariatric surgery that contribute to the alleviation of metabolic dysfunction-associated steatotic liver disease (MASLD) have been reported. However, the processes and mechanisms underlying the contribution of lipid metabolic reprogramming after bariatric surgery to attenuating MASLD remain elusive. METHODS: A case-control study was designed to evaluate the impact of three of the most common adipokines (Nrg4, leptin, and adiponectin) on hepatic steatosis in the early recovery phase following sleeve gastrectomy (SG)...

BACKGROUND: Monogenic autoinflammatory disorders result in a diverse range of neurological symptoms in adults, often leading to diagnostic delays. Despite the significance of early detection for effective treatment, the neurological manifestations of these disorders remain inadequately recognized. METHODS: We conducted a systematic review searching Pubmed, Embase and Scopus for case reports and case series related to neurological manifestations in adult-onset monogenic autoinflammatory diseases...
