Objective To explore the diagnosis and clinical characteristics of atypical severe pneumonia caused by Chlamydia abortus(C.abortus).Methods Clinical data of 4 patients diagnosed with atypical severe pneumonia caused by C.abortus in a hospital from January 2021 to November 2022 were collected.Clinical characteristics,dia-gnosis and treatment,and precautions of the disease were comprehensively analyzed.Results All 4 patients were male,aged 63-73 years old,with acute onset,high fever,cough and expectoration.Three patients had a history of contact with poultry,one patient had a history of contact with abortion goat.The interval between the emerging of clinical symptoms and the onset of acute respiratory failure in 4 patients was 1-6 days,and the oxygenation index(PaO2/FiO2)at admission was less than 200 mmHg,which gradually decreased with the progression of the disease,active support with a ventilator was necessary.Two patients had an increase in white blood cell count,4 had an in-crease in neutrophil percentage,3 had a mild decrease in platelet count.Among 4 patients,2,2,3 and 4 patients showed elevated levels of aspartate aminotransferase,alanine aminotransferase,creatine kinase,and serum creati-nine respectively,2 patients had mild hyponatremia,4 patients showed significant increase in C-reactive protein,procalcitonin,and interleukin-6 levels.Four patients'chest CT findings showed main involvement of single or mul-tiple lung lobes,with exudation and consolidation,and later involvement of multiple lobes of lung.The metageno-mic next-generation sequencing of bronchoalveolar lavage fluid detected the DNA sequence of C.abortus.Based on the clinical manifestations,contact history,chest CT,and metagenomic next-generation sequencing results of 4 pa-tients,the diagnosis was C.abortus.atypical severe pneumonia.After timely adjustment of the treatment of anti-in-fection regimen based on doxycycline,the patients'condition improved and were discharged.Conclusion C.abor-tus may also cause human pneumonia,which can lead to serious clinical outcome after infection.Patient had a histo-ry of animal contact should be alert to such diseases.Metagenomic next-generation sequencing can detect C.abortus.

Incidental finding of an atypical cartilaginous tumor in an adult female with recurrent patellar dislocation: Single-stage extended curettage using freezing nitrogen ethanol composite followed by Medial Patello-Femoral Ligament Reconstruction

@#Atypical cartilaginous tumor (ACT) refers to a low-grade cartilaginous neoplasm microscopically identical to grade 1 chondrosarcoma, affecting the appendicular skeleton. Treatment with intralesional curettage has been found to provide sufficient local control with less morbidity compared to wide resection. This is the first reported case of a simultaneous medial patello-femoral ligament (MPFL) reconstruction with extended curettage for ACT on the ipsilateral femur. A 45-year-old female presented with chronic recurrent patellar dislocation of the right knee. Magnetic resonance imaging revealed a tear of the MPFL, with an incidental epi-metaphyseal chondroid lesion. After biopsy confirmed an ACT, single-stage extended curettage using freezing nitrogen ethanol composite (FNEC) and MPFL reconstruction was performed, followed by augmentation with bone cement and a distal femoral plate. Currently, the patient is independently ambulatory, with full range of motion about the knee. Following histologic confirmation of an ACT in the setting of a concurrent MCL tear, a single-stage procedure to address both conditions is a viable option that can reduce complications associated with multiple surgeries. Extended curettage using FNEC has been shown to produce good short-term oncologic outcomes while maximizing function.

Congenital intrabdominal hernia with atypical pain as first manifestation:A case report and literature review / 吉林大学学报(医学版)

Objective:To discuss the clinical characteristics,diagnosis processes,and treatment methods of one patient with congenital intrabdominal hernia,and to summarize the potential misconceptions during the diagnostic and treatment processes,and to improve the clinicians'awareness of this disease.Methods:The clinical data and auxiliary examination results of one patient with congenital intrabdominal hernia were collected and analyzed,and the related literatures were reviewed.Results:The patient,a 65-year-old male,sought care at the local hospital due to upper abdominal pain before 2 d;there were no significant abnormalities in the examination results at the cocal hospital;blood glucose>25 mmol·L-1.After receiving hypoglycemic,rehydration,and blood purification treatment,the condition of the patient was worsened,presenting with confusion,hypotension,and respiratory distress;the patient admitted in our hospital for further diagnosis and treatment.After admission,the patient was given despite fluid resuscitation,mechanical ventilation,and supportive treatment,but there was no improvement in the symptoms;interventional radiology was performed angiography of the abdominal artery and right femoral vein,which showed no significant vascular abnormalities in the abdomen.An abdominal paracentesis yielded a mixed bloody fluid,suggesting the concealed intraperitoneal disease;exploratory laparotomy was performed.During operation,the intrabdominal hernia with small intestine necrosis and septic shock were diagnosed,and partial small intestine resection,anastomosis,adhesiolysis,and abdominal irrigation and drainage were carried out.The patient had a good recovery and was discharged on the 14th day after operation.Conclusion:Congenital intrabdominal hernia is a very rare cause of intestinal obstruction in the adults,and high suspicion for intrabdominal hernia is one of the differential diagnosis for atypical acute abdomen;early multidisciplinary intervention can be lifesaving for the patients.

Exploring atypical manifestations of Mpox: A narrative review

Mpox (formerly referred to as monkey pox), a viral infection known for its characteristic manifestations, presents with atypical symptoms, leading to diagnostic and management challenges. Recent outbreaks of the disease have also revealed changes in the epidemiologic patterns of the disease with many cases going unnoticed. These scenarios if not properly identified and addressed can led to increased healthcare burden created by the virus. To conduct the narrative review of the concerned literature, a comprehensive and well through search from PUBMED, Google scholar, EMBASE and African Journal Online Evaluating Studies was conducted from published works between 2003 to 2023. This narrative review aims at exploring the atypical manifestations of Mpox, by reviewing various manifestations of the disease, examining the overlying mechanisms and factors influencing these manifestations; and more so, assessing various clinical implications and challenges facing its management, with the hope of suggesting future directions in tackling the clinical implications and challenges. Regarding the atypical manifestations of Mpox, the review focused on the neurological, dermatological, and respiratory presentations, highlighting the diverse symptoms observed in each case. In addition, accurate diagnosis of atypical cases is crucial and requires a high index of suspicion, comprehensive differential diagnosis, and appropriate diagnostic testing. Tailored strategies for treatment are essential to address the specific manifestations observed. For future research, a focus on elucidating the pathogenesis, identifying risk factors, improving diagnostic approaches, and evaluating treatment strategies for atypical

Presentación atípica de fiebre chikungunya en cuidados críticos / Atypical clinical presentation of chikungunya fever in critical care

Resumen El virus Chikungunya es un Alfavirus de la familia Togaviridae trasmitido por mosquitos. Fue descrito por primera en un brote en el sur de Tanzania en 1952. Genera clásicamente un síndrome febril con poliartral gias y artritis, que pueden ser incapacitantes y tener una duración prolongada. La mortalidad global ronda en 0.1%. Existen reportes en la literatura de presenta ciones atípicas y graves con compromiso de múltiples órganos. Se ha detectado la presencia del virus en más de 110 países. En Brasil, en la región noreste, se han hallado casos autóctonos desde septiembre de 2014. En Argentina y países limítrofes, se presentan casos en aumento duran te 2023, con respecto a iguales periodos en años previos. Hasta la semana epidemiológica N° 26 del año 2023 se registraron en Argentina 1460 casos de fiebre chikun gunya, considerándose autóctonos 72% de ellos. Se presenta el caso de una mujer de 76 años, con an tecedentes de hipertensión arterial y estenosis aortica, admitida en terapia intensiva por shock séptico con foco respiratorio, con patrón de neumonía intersticial, evolu ción tórpida y óbito dentro de las 24 horas del ingreso. Se recibe postmorten el resultado detectable de virus Chikungunya por reacción en cadena de la polimerasa en tiempo real. Este caso, resulta de importancia clínica dada la pre sentación atípica del mismo y por la baja prevalencia nacional de infecciones graves por dicho virus, alerta sobre la necesidad de incluir el diagnóstico diferencial en los pacientes con sospecha diagnóstica.

Abstract Chikungunya virus is an Alphavirus, it belongs to the family Togaviridae and is transmitted by mos quitoes. It was first described during an outbreak in Southern Tanzania in 1952. It generally causes a febrile syndrome, accompanied by joint pain and arthritis, which is often debilitating and may persist for months or years. Its overall fatality rate is not high, around 0.1%. Atypical and severe cases have been reported. This virus has been detected in more than 110 countries globally. In Northeastern Brazil autoch thonous cases have been diagnosed since September 2014. In Argentina, as well as in neighboring countries, cases were increasing during 2023, compared to the same periods in previous years. Until epidemiological week 26 of 2023, 1460 cases of chikungunya fever were reported in Argentina, 72% of them were considered of autochthonous transmission. The case of a 76-year-old female patient is here presented, her comorbidities were hypertension and aortic stenosis, who was admitted to intensive care unit due to septic shock with respiratory focus, intersti tial pneumonia in X-ray pattern, and torpid evolution. She died within 24 hours of admission. A report of detectable Chikungunya virus by real-time polymerase chain reaction in real time was received post-mortem. This case results of clinical relevance due to its atypi cal presentation and the country low prevalence of severe infections by this virus. It warns of the need to include the differential diagnosis in cases with sus pected diagnosis.

Secondary oral syphilis presenting as a tumor-like lesion on the lower lip

ABSTRACT This study presents a case of atypical manifestation of secondary syphilis. Diagnosis was initiated prompted by the patient's complaint of a lower lip lesion, present for three months, resembling a malignant neoplasm. The lesion, a 3 cm (diameter) ulcerated nodule, arising from conjunctive tissue, raised concern. However, further physical examination revealed additional clinical features, including cervical micropolyadenopathy and erythematous skin lesions, prompting a reevaluation of the diagnosis, most likely secondary syphilis. These findings led to a serological investigation, which, ultimately, confirmed the diagnosis of syphilis. The case underscores the importance of recognizing syphilis as a formidable imitator, posing challenges in establishing differential diagnoses of mucocutaneous diseases.

Long-term consequences of osteoporosis therapy with bisphosphonates

ABSTRACT Bisphosphonates (BPs) are medications widely used in clinical practice to treat osteoporosis and reduce fragility fractures. Its beneficial effects on bone tissue have been consolidated in the literature for the last decades. They have a high affinity for bone hydroxyapatite crystals, and most bisphosphonates remain on the bone surface for a long period of time. Benefits of long-term use of BPs: Large and important trials (Fracture Intervention Trial Long-term Extension and Health Outcomes and Reduced Incidence with Zoledronic acid Once Yearly-Pivotal Fracture Trial) with extended use of alendronate (up to 10 years) and zoledronate (up to 6 years) evidenced significant gain of bone mineral density (BMD) and vertebral fracture risk reduction. Risks of long-term use of BPs: The extended use of antiresorptive therapy has drawn attention to two extremely rare, although severe, adverse events. That is, atypical femoral fracture and medication-related osteonecrosis of the jaw are more common in patients with high cumulative doses and longer duration of therapy. BPs have demonstrated safety and effectiveness throughout the years and evidenced increased BMD and reduced fracture risks, resulting in reduced morbimortality, and improved quality of life. These benefits overweight the risks of rare adverse events.

Isolation and characterisation of Leishmania (Leishmania) infantum from cutaneous leishmaniasis patients in northeast Brazil

BACKGROUND In Brazil, Leishmania (Leishmania) infantum is a widely distributed protozoan parasite. The human leishmaniasis caused by this species is often associated with visceral form. Tegumentary leishmaniasis (TL) cases due to L. (L.) infantum in the country are considered rare but may be underestimated. Although probably uncommon, these cases represent a new challenge to the prevention and control of leishmaniasis. OBJECTIVES Here, we describe two distinct cases of TL with atypical clinical presentations caused by L. (L.) infantum. METHODS AND FINDINGS Parasites were isolated from cutaneous lesions of the two patients and typed as L. (L.) infantum after sequencing of the ribosomal DNA internal transcribed spacer. The dermotropic L. (L.) infantum isolates were compared in terms of growth culture patterns, metacyclogenesis and in vitro infectivity in macrophages. MAIN CONCLUSIONS This study addresses the emergence of L. (L.) infantum as a causative agent of cutaneous disease in a visceral leishmaniasis hotspot located in northeast Brazil. The data presented provides novel information about the presence of dermotropic L. (L.) infantum in the country and demonstrates the infectivity potential of theses isolates.

Here, a case is described of chronic myeloid leukemia presenting in the blast phase with a rare variant transcript, with a discussion on possible red flags in its detection and genetic testing and description of the patient's clinical characteristics. This case highlights the pitfalls of using real-time quantitative reverse-transcription polymerase chain reaction (RQ-PCR) for diagnosis of CML, especially when the clinical picture and the test results are discordant.

Enfermedad del legionario en Argentina: evolución de la estrategia diagnóstica en el laboratorio / Legionnaires' disease in Argentina: Evolution of the laboratory diagnostic strategy

Resumen La enfermedad del legionario (EL) es una neumonía aguda grave, que ocurre espo-rádicamente o como epidemias, y que, generalmente, requiere hospitalización. El objetivo deeste trabajo fue describir la experiencia en el abordaje diagnóstico de laboratorio de la ELen Argentina durante el período 2016-2021. Se analizaron 168 especímenes clínicos correspondientes a 93 casos de neumonía con sospecha de EL. Las pruebas de laboratorio incluyeron ladeterminación del antígeno soluble de Legionella pneumophila serogrupo 1 en orina, la detec-ción de ADN de Legionella spp. en secreciones respiratorias bajas, por métodos moleculares convencionales y comerciales de tipo sindrómico, y el cultivo en medio selectivo. Se confirmó EL en 12 pacientes. El antígeno urinario confirmó el diagnóstico de 8 de ellos. Se recuperó L. pneumophila mediante el cultivo del material respiratorio de 6 pacientes que correspondieron a casos de neumonía asociada a cuidados de la salud y que fueron previamente diagnosticados por el método molecular comercial. La mitad de ellos no presentó antigenuria detectable. En un único paciente no hubo antigenuria detectable ni recuperación de Legionella en cultivo, y la confirmación de EL se basó en la detección de ADN de Legionella spp. por PCR en secreción respiratoria y el vínculo epidemiológico con otro caso de EL confirmado por cultivo. La detección del antígeno urinario es la prueba diagnóstica de primera línea. Sin embargo, la incorporación de métodos moleculares complementarios ha demostrado evitar falsos negativos y contribuir a un mejor conocimiento de la verdadera incidencia de la enfermedad.

Abstract Legionnaires' disease (LD) is severe acute pneumonia that occurs in sporadic or epidemic form, and generally requires hospitalizaron. The objective of this work was to describe the experience in the LD laboratory diagnostic approach in Argentina during the period 2016-2021. The laboratory analyzed 168 clinical specimens from 93 cases of suspected LD pneu-monia. Laboratory tests included the detection of the soluble antigen of Legionella pneumophila serogroup 1 in urine sample, detection of DNA of Legionella spp. in lower respiratory secre-tions by conventional and commercial molecular methods and isolation in selective medium. LD was confirmed in 12 patients. The urinary antigen allowed the diagnosis for 8 patients. L. pneumophila was isolated from the respiratory material of 6 patients suffering from health care-associated pneumonia, who had been previously diagnosed using the commercial molecular method. Fifty percent of these cases did not show detectable urinary antigen. A single patient did not shows neither detectable antigenuria nor isolation of Legionella from the respiratory sample and was diagnosed as a confirmed case of LD by the detection of DNA of Legionella spp. by PCR directly from the respiratory secretion and the epidemiological link with another case of confirmed LD by culture. Urinary antigen detection is the first-line diagnostic test. However, the incorporation of complementary molecular methods has proved to avoid false negatives and contributed to a better understanding of the true incidence of the disease.

Evaluation of adverse drug reactions in patients of schizophrenia in tertiary care teaching hospitals in Central India

Background: For decades, it has been observed that mental health is shrouded in stigma and discrimination. The scope, severity, and expense of impairment and costs to people, families, and societies are staggering. Mental illnesses are among the most frequent illnesses, affecting over a quarter of the population in any given year. According to national institute of mental health and neurosciences, Bangalore, the prevalence of schizophrenia has been considered as 4/1000 for all ages and both sexes. Aim and Objectives: The objectives of this study were to as follows: (1) To evaluate adverse drug reactions (ADRs) in patients with schizophrenia who received antipsychotic treatment and (2) to compare ADRs in typical versus atypical antipsychotic agents in schizophrenic patients. Materials and Methods: A total of 50 schizophrenic patients were enrolled for evaluating adverse effects to antipsychotic drugs. During the research, all ethical precautions were taken. All patients were followed up by medical history, history of drugs, and any severity of adverse drug reaction. Causality assessment was graded by Naranjo scale. Result: Among all of the antipsychotic drugs, risperidone (05%), quetiapine (04%), and aripiprazole (04%) have shown lowest propensity to cause serious adverse event. These drugs are most commonly prescribed drugs and are least likely to affect quality of life of patient. However, the risk of extrapyramidal symptoms is lower with olanzapine (05%) than haloperidol (34%) and even in case with risperidone at higher dose (20%). Although atypical antipsychotics such as olanzapine (46%) have shown maximum potential to produce metabolic side effect such as dyslipidemia and hyperglycemia compared to that of other antipsychotics. Conclusion: The most common adverse effects were found with typical and atypical antipsychotics such as weight gain, drowsiness, constipation, sedation, dyslipidemia, and hypotension.

Infratentorial atypical choroid plexus papilloma in an adult: A case report and literature review

Atypical choroid plexus papilloma is classified as WHO (World Health Organization) Grade II subtype of choroid plexus tumor, and it has intermediate pathological features, prognosis, and clinical outcome rates between choroid plexus papilloma and choroid plexus carcinoma. These tumors are more common in children compared with adults and are usually located in the lateral ventricles. We present a case of an adult with atypical choroid plexus papilloma located in the infratentorial region. A 41?year?old woman underwent evaluation for headache and dull aching neck pain. Magnetic resonance imaging (MRI) of the brain revealed a well?defined intraventricular mass lesion in the fourth ventricle and foramen of Luschka. She underwent craniotomy and gross total excision of the lesion. Histopathological and immunohistochemical findings confirmed the diagnosis of atypical choroid plexus papilloma (WHO Grade II). We discuss the various treatment options for this condition and review the relevant literature.

An Unusual Case of DRESS Syndrome Presenting with Marked Leucocytosis.

Drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is a rare severe drug-induced idiosyncratic hypersensitivity characterized by maculopapular and/or erythrodermic eruption, fever, peripheral lymphadenopathy, eosinophilia or atypical lymphocytosis, and visceral organ involvement. The estimated incidence of this syndrome ranges from 1/1000 to 1/10,000 drug exposures. In this report, we describe a case of DRESS syndrome in a young female with a unique presentation. The DRESS syndrome can be difficult to diagnose as its clinical findings can mimic those of other systemic diseases. This case emphasizes the importance of incorporation of the patient’s clinical and medication history in the interpretation of hematological investigations.

Cognitive decline among older adults who developed acute coronary syndrome during hospitalization for non-cardiac illness

Background: Atypical presentations of acute coronary syndrome (ACS) delay its recognition and treatment in the elderly patients. Functional decline and delirium which are common to the elderly during hospitalization, leads to cognitive impairment and poor health outcomes. Steps taken for its prevention is usually not considered the top priority by the cardiologist. The present study was conducted to identify cognitive decline among elderly patients who developed ACS during hospitalization for noncardiac illness and their outcome. Materials and Methods: Three hundred and ten elderly patients above 60 years of age with ACS were included from June 26, 2020 to October 13, 2020. Subjects were divided into those admitted primarily due to an ACS (Group I, n = 94) and those developing ACS following admission for noncardiac illness (Group II, n = 216). Co-morbidities, medications, investigations, management, clinical outcome, and Montreal Cognitive Assessment scale were compared between the two groups at the time of admission, after 30 days and after 6 months. Results: Majority of the subjects were admitted due to acute kidney injury (27.1%) in Group II and had a non-ST elevation ACS (90.2%). Optimum management was given to a lesser extent due to the clinical condition of these patients. Poor clinical outcome, cognitive impairment during hospitalization and cognitive decline during follow-up was more in Group II. Conclusion: Clinicians must be vigilant for the development of cognitive impairment and cognitive decline when an elderly patient is admitted to the hospital, as early detection and optimum management provides better clinical and cognitive outcome.

The research progress on atypical teratoid/rhabdoid tumor of the central nervous system in children / 中国神经精神疾病杂志

Atypical teratoid/rhabdoid tumor(AT/RT)is a rare and highly malignant embryonal tumor of the central nervous system in children,characterized by diverse histological morphology,high malignancy,rapid clinical progression,and poor prognosis for affected children.The pathogenesis of AT/RT involves mutations in chromosomes and genes,particularly the loss of function of the SMARCB1 gene.The diagnosis of AT/RT primarily relies on histological and immunohistochemical analysis.Currently,there is no standardized treatment protocol for AT/RT.The main treatment modalities include surgery,chemotherapy,radiotherapy,as well as emerging targeted therapy and immunotherapy.Despite progress in research and clinical trials on AT/RT in recent years,the prognosis for affected children remains poor,necessitating further research to develop more effective treatment strategies to improve patient outcomes.
