Urinary Incontinence Due to Complete Ureteral Duplication With an Ectopic Vulvar Ureteral Orifice: A Case Report.

Ureteral duplication is one of the most common congenital malformations of the urinary tract and may be complete or incomplete. One of the complications of complete ureteral duplication is an ectopic ureter orifice, which, depending on the opening site, may cause urinary incontinence in females, a condition with potentially serious repercussions on the woman's quality of life. Thus, the present study aims to report the case of a 24-year-old female patient with a complaint of urinary incontinence since childhood. After a physical examination and imaging tests, she was diagnosed with complete ureteral duplication on the left side, associated with sequelar parenchymal atrophy of the upper pole of the left kidney, and ectopic vulvar ureter. The patient underwent a videolaparoscopic left upper polar nephrectomy, and her symptoms improved after surgery. This report intends to add to already available data in the literature, highlighting the relevance of anamnesis and physical examination in reaching a diagnosis and implementing appropriate treatment, thus improving the quality of life of individuals with this condition. In addition, these data should be useful both for the medical community and for future studies on this malformation.

In vitro Evaluation of Isoniazid Derivatives as Potential Agents Against Drug-Resistant Tuberculosis.

The upsurge of multidrug-resistant tuberculosis has toughened the challenge to put an end to this epidemic by 2030. In 2020 the number of deaths attributed to tuberculosis increased as compared to 2019 and newly identified multidrug-resistant tuberculosis cases have been stably close to 3%. Such a context stimulated the search for new and more efficient antitubercular compounds, which culminated in the QSAR-oriented design and synthesis of a series of isoniazid derivatives active against Mycobacterium tuberculosis. From these, some prospective isonicotinoyl hydrazones and isonicotinoyl hydrazides are studied in this work. To evaluate if the chemical derivatizations are generating compounds with a good performance concerning several in vitro assays, their cytotoxicity against human liver HepG2 cells was determined and their ability to bind human serum albumin was thoroughly investigated. For the two new derivatives presented in this study, we also determined their lipophilicity and activity against both the wild type and an isoniazid-resistant strain of Mycobacterium tuberculosis carrying the most prevalent mutation on the katG gene, S315T. All compounds were less cytotoxic than many drugs in clinical use with IC50 values after a 72 h challenge always higher than 25 µM. Additionally, all isoniazid derivatives studied exhibited stronger binding to human serum albumin than isoniazid itself, with dissociation constants in the order of 10-4-10-5 M as opposed to 10-3 M, respectively. This suggests that their transport and half-life in the blood stream are likely improved when compared to the parent compound. Furthermore, our results are a strong indication that the N' = C bond of the hydrazone derivatives of INH tested is essential for their enhanced activity against the mutant strain of M. tuberculosis in comparison to both their reduced counterparts and INH.

Predicting Prognosis in Internal Medicine: A Short and Long-Term Mortality Comparison Analysis.

Introduction The marked increase in life expectancy seen in Portugal in the last five decades led to a change in the profile of patients being most commonly admitted in internal medicine wards. In deciding the best care for these patients, prognostication models are needed in order to reduce readmissions, mortality, and adequate care. We aimed to study short and long-term mortality and predictors of all-cause mortality, independently of cause admission, of patients admitted in an internal medicine ward. Methods This two-part, single-center study enrolled patients from October 2013 to October 2014 with a follow-up of 60 months. Results A total of 681 patients were included; the mean age was 75.86 years with 60.4% females. The most frequent comorbidities were anemia, hypertension, and renal impairment. More than half of the population died in the follow-up period (51.5%). Deaths were significantly higher in the first six months after discharge (53% of all deaths) and then decreased abruptly to 11.6% in the second half-year after discharge. Based on the multivariate logistic regression model, with age over 80 years, anemia and neoplasm were independent predictors of short-term (p<0.001, p=0.001, p<0.001, respectively) and long-term (p<0.001 for the three conditions) mortality. Heart failure (p=0.018) and diabetes (p=0.025) were also predictors of long-term mortality. Conclusion High mortality, mainly in the first six months after discharge, elicits strategies targeting transition of care and close follow-up in the first months, which can be the key to improving outcomes. Identification of patients at higher risk may help design realistic models aiming to improve care for this frail population and decrease morbimortality.

Thinking Outside the Box.

Clinical decision-making process is very complex and influenced by multiple aspects. As diagnosis likelihood assessment is often based on intuitive thinking, data misinterpretation, and diagnostic errors may commonly occur. We present a peculiar clinical case of a 27-year-old obese woman admitted to the emergency department after an inaugural episode of seizures. She had an oncologic disease. She was febrile and hypertensive at first evaluation. The report evolves around the diagnostic assessment, hampered by incongruent anamneses, incorrect data interpretation, and a pinch of clinical obstination, which nearly culminated in two deaths. Then, we discuss the series of biases that have confused the physicians. The only way to escape the intuitive thinking trap is to be humbly aware of our own thinking method's limitations and to learn about the biases that often lead us into errors. Sometimes, thinking outside the box is the key.

"Keeping the Light On": A Qualitative Study on Hope Perceptions at the End of Life in Portuguese Family Dyads.

Hope performs an important role in how patients and their families cope with suffering and stressful events. To better inform practice and theory on hope, palliative care research should include both patients and their family carers, given their strong interdependence. The aim of this study was to explore how hope is experienced in dyads formed by end-of-life patients and their family carers. In this qualitative study, data were collected by in-depth interviews with seven Portuguese family dyads. Analysis followed a thematic analysis approach. The analysis of the interviews shed light on the importance of hope for all participants, and the challenges involved. Family dyads noted several barriers and facilitators to perceptions of hope. Barriers to hope included limitations imposed by illness, feelings of anguish and helplessness, and poor communication with clinicians. Hope facilitators included supportive others, positive thinking and sense of humour, connection with nature, faith in religion and science, and a sense of compassion with others and altruism. Given the multidimensional scope of hope, the main challenge for family dyads is to look beyond the disease itself. Thus, palliative care teams should be encouraged to support and foster realistic hope, helping families prepare for death, in the context of advanced cancer.

Kikuchi-Fujimoto Disease: Diagnosis in a Relapsing Case.

The differential diagnosis of cervical lymphadenopathy is varied. Different age groups require different approaches. Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a rare but important diagnosis to consider after excluding more common aetiologies. We present the case of a 21-year-old female with painful left cervical swelling, lasting over a week. Physical examination revealed multiple cervical lymphadenopathies, elastic, non-adherent to deep tissues which were tender to touch. Blood tests showed elevated acute phase proteins. Cytomegalovirus, Epstein-Barr, toxoplasmosis, and human immunodeficiency virus serologies were negative. Computed tomography of the neck revealed multiple cervical lymphadenopathies which were round-shaped, some with necrosis and with extracapsular extent. These features could be compatible with tuberculous lymphadenitis. However, interferon-gamma release assay was negative. Excisional biopsy was scheduled, but spontaneous regression did not allow it. Two weeks later she relapsed. Excisional biopsy revealed histiocytic necrotizing lymphadenitis. Kikuchi-Fujimoto's diagnosis demands high clinical suspicion and histological documentation. This case represents a rare diagnosis of a relapsing disease.

Designing new antitubercular isoniazid derivatives with improved reactivity and membrane trafficking abilities.

Isoniazid (INH) is one of the two most effective first-line antitubercular drugs and is still used at the present time as a scaffold for developing new compounds to fight TB. In a previous study, we have observed that an INH derivative, an hydrazide N'-substituted with a C10acyl chain, was able to counterbalance its smaller reactivity with a higher membrane permeability. This resulted in an improved performance against the most prevalent Mycobacterium tuberculosis (Mtb) resistant strain (S315T), compared to INH. In this work, we have designed two new series of INH derivatives (alkyl hydrazides and hydrazones) with promising in silico properties, namely membrane permeabilities and spontaneous IN* radical formation. The kinetics, cytotoxicity, and biological activity evaluations confirmed the in silico predictions regarding the very high reactivity of the alkyl hydrazides. The hydrazones, on the other hand, showed very similar behavior compared to INH, particularly in biological tests that take longer to complete, indicating that these compounds are being hydrolyzed back to INH. Despite their improved membrane permeabilities, the reactivities of these two series are too high, impairing their overall performance. Nevertheless, the systematic data gathered about these compounds have showed us the need to find a balance between lipophilicity and reactivity, which is paramount to devise better INH-based derivatives aimed at circumventing Mtb resistance.

Mitral Valve Subacute Endocarditis Caused by Abiotrophia Defectiva: A Case Report.

Abiotrophia defectiva is a rare agent of endocarditis and subacute presentation may delay the diagnosis. We present the case of a 41-year-old male who was admitted to the hospital for further investigation regarding a consumptive syndrome with microcytic anaemia. Past medical history included new-onset mitral insufficiency followed by an ischaemic stroke due to small vessel disease. Thoraco-abdominal computed tomography revealed a splenic infarction. In the presence of two ischaemic events associated with mitral valve disease of unknown aetiology, we considered the possibility of subacute endocarditis. Blood cultures were positive for Abiotrophia defectiva, and transoesophageal echocardiography confirmed the diagnosis. As a subacute presentation of endocarditis, the paucity of symptoms caused a five-month delay in diagnosis. New-onset valvular disease and a stroke in an otherwise healthy young patient should always prompt proper investigation. This case highlights several complications caused by septic emboli of undiagnosed and untreated endocarditis.

Total Pain Management and a Malignant Wound: The Importance of Early Palliative Care Referral.

Breast cancer may metastasize to the lung, liver, bone, brain, and skin, with especially high rates of metastasis to skin sites.These skin metastases are called malignant wounds. Patients with malignant wounds often report multiple symptoms, and pain is one of the most common and distressing among them. Despite the availability of multiple guidelines about treatment to relieve pain, almost half of all cancer patients still receive inappropriate care for pain. A multidisciplinary approach can improve outcomes in terms of symptom control and quality of life and enable the detection of previously unmet needs of both patients and caregivers. Palliative care is a multidisciplinary therapy that aims to alleviate physical, psychological, and emotional suffering in patients at any stage of the disease. We present the case of a 53-year-old male with a three-year history of stage IV breast cancer. He was admitted to the internal medicine ward in July 2021 with uncontrolled pain related to a malignant wound in the left hemithorax. This was a case with physical, emotional, social, and existential factors contributing to severe pain, necessitating a multidisciplinary approach for adequate relief. Opioid titration and insomnia and anxiety treatment were initiated. Dressing care was applied with metronidazole impregnation and aminocaproic acid for hemorrhagic spots, followed by fat gauze. He was proposed to undergo antalgic radiotherapy, which was unfortunately associated with new onset of symptoms. Psychological support was provided for the patient and his family. We managed to control the pain and stabilize the wound; however, cachexia become evident with the disease progression. In the last week of his life, the patient still believed he would be able to undergo chemotherapy. He died in the emergency room, where he had gone to seek relief for uncontrolled symptoms. Even though the patient had an incurable disease associated with immense suffering since early 2019, he was only referred to the palliative care team during the last three months of his life. Existential suffering was an important dimension of this patient's pain and was present until his death despite receiving psychological support. Late referral to palliative care is unfortunately frequent and often associated with poor quality of life and inability to plan or make end-of-life care decisions. Radiotherapy was proposed for pain control but was associated with serious side effects. In a palliative care setting, decision-making always needs careful consideration related to benefit versus harm and must involve the patient and his family. Living with stage IV cancer is an everyday challenge for patients, and clinicians may also find managing such patients very arduous and stressful. Symptoms must be actively studied and evaluated from a multidimensional perspective. Managing expectations throughout this process while maintaining hope is a delicate balancing act and should be undertaken by specialized palliative care teams.

Drug-Induced Liver Injury Caused by Amoxicillin/Clavulanate.

Drug-induced liver injury (DILI) has a relatively low incidence, and as it is a diagnosis of exclusion, it can become quite a challenge for the clinician. Amoxicillin/clavulanate continues to be one of the most prescribed antibiotics and only rarely causes liver injury. We report a case of DILI associated with this antibiotic to bring attention to a rare side effect of a very commonly prescribed drug. This is the case of a 71-year-old man, with no relevant past medical history, who presented to the Emergency Department due to jaundice in the previous two weeks, with no immediate identifiable cause. The patient was admitted to our Internal Medicine Ward, and after getting a detailed clinical history and excluding other common and severe causes of liver injury, the diagnosis was made that liver injury was due to amoxicillin/clavulanate intake, thus demonstrating the importance of an in-depth history.

Deep venous thrombosis of lower limbs in adolescents: a study in a tertiary hospital.

BACKGROUND: Venous thromboembolism (VTE) - which includes deep venous thrombosis (DVT) and pulmonary embolism (PE) - has been increasingly recognized in the pediatric population. The estimated incidence is 0.07-0.14 cases per 10,000 children. Most cases are associated with two or more risk factors. Medium and long-term complications include recurrence and post-thrombotic syndrome (PTS). OBJECTIVE: To characterize the adolescent population with the diagnosis of DVT of lower limbs in a tertiary hospital, regarding its clinical presentation, associated risk factors, treatment and outcome. METHODS: Retrospective analysis of adolescents with the diagnosis of DVT of lower limbs in our hospital for a period of 7 years. RESULTS: Eight patients were identified; seven were females; median age was 15 years. The main symptoms were local pain and edema. Left lower limb was affected in six patients. PE occurred in two cases. Positive family history of venous thromboembolism was found in five patients. Seven patients had at least two identifiable risk factors. Combined oral contraceptive pill use was the most common (seven patients). Factor V Leiden mutation was found in three patients and protein C deficiency in one. Iliac vein compression syndrome was diagnosed in one patient. The median time for discharge was 8 days. Election treatment was enoxaparin followed by warfarin, for a median period of 10.9 months. Three patients developed PTS. CONCLUSIONS: Although uncommon, VTE is an emerging reality in adolescents, particularly in females using oral contraceptive pills. Appropriated prevention strategies and treatment are required as most orientations are extrapolated from adults.

[Hemothorax - a conservative approach in a patient with multiple comorbidities]. / Hemotórax ­ uma abordagem conservadora em doente com múltiplas comorbilidades.

The authors present the case of an elderly woman with multiple comorbidities hospitalized with the diagnosis of community- acquired pneumonia with pleural effusion. However, there was a history of fall with chest trauma 1 week before, coinciding with the onset of symptoms. The patient had a massive hemothorax that could not be drained. There was a progressive worsening of the patient clinical status with sustained fever and arising of inflammatory parameters, despite broad-spectrum antibiotic therapy and antipyretics. The case was discussed in a multidisciplinary team, and the possibility of surgical intervention was rejected. As life-saving therapy, it was decided to perform fibrinolysis with tissue plasminogen activator, through the thoracic drain, which occurred successfully and without complications. The hemothorax was drained completely allowing recovery of the patient.

Os autores apresentam o caso de uma mulher idosa, com múltiplas comorbilidades, internada com o diagnostico de pneumonia adquirida na comunidade com derrame pleural. No entanto, após nova história clínica constatou-se haver antecedentes de queda com traumatismo torácico 1 semana antes, coincidente com o início dos sintomas, sendo o derrame pleural um volumoso hemotórax que não foi possível drenar. Observou-se um agravamento progressivo do quadro clínico da doente com febre mantida e agravamento dos parâmetros inflamatórios, apesar da antibioterapia de largo espectro e terapêutica antipirética fixa. O caso foi discutido em equipa multidisciplinar, tendo sido rejeitada a hipótese de intervenção cirúrgica. Como terapêutica de life-saving, optou-se por realizar fibrinólise com fator ativador do plasminogénio tecidual, através do dreno torácico, o que ocorreu com sucesso e sem complicações. O hemotórax foi drenado na totalidade permitindo a recuperação da doente.

Risk behaviors in adolescence - a study in a Portuguese health unit.

INTRODUCTION: Adolescence is a time of social and self-affirmation, search of autonomy and pleasure. An early sexual debut and substance use are still public health problems. OBJECTIVES: To assess the prevalence of illicit drug use and sexual behavior of adolescents, ages 15- 17, followed in a Portuguese Family Health Unit. MATERIAL AND METHODS: This was a cross sectional descriptive study of a random convenience sample. Data were obtained from an anonymous and confidential questionnaire, given to patients at adolescent consultation, between the months of May and July 2016. Statistical significance p < 0.05. RESULTS: This study involved a sample of 134 adolescents, 54.5% girls. It was revealed that 73.1% of adolescents have tried alcohol, from which 18.7% experienced intoxication at least once. Regarding tobacco, 35.1% have tried it, 23.4% are regular users. Regarding cannabinoids, 7.5% of adolescents stated to have tried them once, or to consume them regularly. Adolescents start to experiment with tobacco earlier than with alcohol (9 years old vs. 11 years old), with a mean age of 15 years old. Regarding sexual behavior, 23.8% are sexually active, from which 9.4% do not use any form of contraception. Smoking behavior was a predictor of the consumption of illicit drugs, and it was found a significantly statistic association between sexual activity and substance use, p = 0.04. DISCUSSION: By descending order, the alcohol, tobacco and illicit drugs consumption are still worrisome and can affect the life of adolescents. Primarily health care and pediatric consultation should provide strategies for prevention and promotion of a healthy lifestyle for adolescents.

Herpes zoster with cutaneous dissemination: a rare presentation of an uncommon pathology in children.

Herpes zoster, caused by varicella zoster virus (VZV) reactivation, affects mainly the adult population, although it can occur in children. This happens when primary infection (varicella) has occurred at a very young age or in immunocompromised patients. Complications are rare in healthy individuals. They include VZV cutaneous dissemination, which affects 2%-10% of immunocompromised patients.We present a previously healthy child, with history of varicella during her first month of life, which presented at age 8 with a severe case of herpes zoster, complicated with cutaneous dissemination. Immunity study was unremarkable. Causes, management and follow-up are discussed.

Acute Anaemia: A Challenging Diagnosis.

Acute anaemia is characterized by a reduction in the number of red blood cells, haemoglobin levels or haematocrit. By far the most common aetiology is haemorrhage, but in its absence other less frequent causes should be considered. The authors present the case of a 42-year-old man with a diagnosis of glucose-6-phosphate deficiency and progressing gastric signet ring cell carcinoma, who was admitted to the internal medicine department for symptomatic back pain control. During his hospitalization, the patient developed acute anaemia with schistocytes on peripheral blood smear with no concurrent hyperbilirubinaemia or decreased haptoglobin. Bone metastatic disease was documented. The case was revised with the transfusion medicine department and malignancy-associated microangiopathic haemolytic anaemia (Ma-MAHA) was suggested. The patient was transferred to the oncology department and later discharged, dying at home shortly afterwards. LEARNING POINTS: The possibility of multiple aetiologies for anaemia in the same patient should be considered.Pathophysiological mechanisms are important in the differential diagnosis of anaemia.Malignancy-associated microangiopathic haemolytic anaemia can present as a paraneoplastic syndrome.
