Asymptomatic and underreported individuals remain a source of coronafig disease 2019 (COVID-19) transmission to others. Data on the prevalence and epidemiological factors influencing transmission are fundamental for establishing control measures, especially in vulnerable regions such as the Amazon. This study aimed to determine the point prevalence and active infection of COVID-19 among the population in Araguaína, a Brazilian city located in the Amazon region, analyzed the socioeconomic and behavioral variables of a statistically representative sample of this population using an epidemiological survey, and identify the viral genomic diversity in the region. During the sixth epidemiological week of 2021 (February 8 to 12), samples of 497 inhabitants of the municipality asymptomatic for respiratory syndromes underwent reverse transcription-quantitative polymerase chain reaction and serological tests (immunoglobulin M and immunoglobulin G). A questionnaire collated data on socioeconomic factors, prevention measures, and health status history. The active infection rate was 6.2%, and the prevalence was 13.5% of the study population. Active infection cases were under-reported; each reported positive case represented 14-28 under-reported cases. Lineages P.2, P.1, and B.1.1 were detected. Working from home was a protective factor against the infection, and clinical signs of fever, dry cough, and loss of taste or smell were associated with testing positive (p <0.05). A descriptive analysis of the indicators revealed that the entire population was susceptible to the disease. Intensified vaccination strategies are required regardless of socioeconomic factors, health conditions, and preventive measures. Implementation of objective, comprehensive, and efficient management tools to minimize the spread of COVID-19 in this municipality can serve as a model for other regions of Brazil.

Giant-cell arteritis (GCA) is a type of vasculitis characterised by the presence of granulomas. It is the predominant form of systemic vasculitis in adults and primarily affects the larger arteries in individuals aged ≥ 50 years. GCA affects the major arteries, such as the aorta and its branches, particularly the outer branches of the external carotid artery. Signs and symptoms can be categorised into cranial, extracranial, and systemic manifestations. Patients with headaches, jaw claudication, and vision disturbances usually have extracranial branches of the external carotid artery. Aside from being the prevailing manifestation of GCA, our primary concern regarding this variant is the potential for irreversible vision loss if not properly identified and addressed. Conversely, the GCA can also affect other major blood vessels such as the aorta. Here, we present the case of a 70-year-old Caucasian female patient with cranial GCA who had experienced a temporal headache three years prior. The patient was successfully treated with prednisolone, which was gradually reduced to a very low level with the assistance of methotrexate. Recently, the patient presented with a dry cough that lasted for two months and elevated inflammatory markers. After thorough research, it was determined that there was no evidence of infection, including atypical infections, and that no abnormalities were found in the lungs. Ultimately, via an 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) scan, the patient was diagnosed with large vessel giant cell arteritis (LV-GCA). This impacted the aorta, carotid arteries, and subclavian arteries. The patient experienced notable improvement in her cough and a reduction in inflammatory markers after receiving a high dosage of oral prednisolone. This case exemplifies the unusual manifestation of LV-GCA and verifies that recurring symptoms may differ from the original presentation. While dry cough is not commonly listed as a symptom of LV-GCA, it can be present as a manifestation or the sole presentation in certain patients, particularly when inflammatory markers are consistently high and there is no pulmonary disease.

KEY CLINICAL MESSAGE
Peripartum cardiomyopathy (PPCM) is a rare cause of heart failure associated with pregnancy without any other known cause. With a prognosis that can vary from the complete recovery of left ventricular function to maternal mortality as well as recurrence with subsequent pregnancies, early diagnosis and treatment of PPCM is important in management. Bromocriptine treatment is beneficial effects on LVEF and mortality in women with severe acute PPCM in addition to standard heart failure therapy. However, further study is required to establish its effect in PPCM.
ABSTRACT
Peripartum cardiomyopathy (PPCM) is a rare cause of heart failure associated with pregnancy without any other known cause. Most of the clinical presentation is similar to symptoms of advanced pregnancy making the diagnosis difficult. Reported are three patients who developed dyspnea, orthopnea, and dry cough during the first week of puerperium. On examination, bilateral lower limb edema and bilateral basal lung crepitation were present in all patients. Chest radiograph showed pulmonary edema in cases two and three, and pleural effusion in case one. All patients had reduced left ventricular ejection fraction and raised N-terminal pro-b-type natriuretic peptide (NT-proBNP) levels. Case two developed PPCM in the background of left pyelonephritis. Case three was complicated by acute kidney injury. All patients were managed with bromocriptine, diuretics, beta-blockers, ACE inhibitors, and fluid restriction. Hence, PPCM though rare should be considered as a differential in women presenting with features of heart failure in later months of pregnancy or within 5 months of delivery.

Enteric fever is a systemic bacterial infection caused by enteroinvasive, gram-negative bacilli, named and . It presents with hectic fever, headache, malaise, bowel habit changes, and abdominal pain. Diagnosis is usually confirmed by blood culture. Gastrointestinal complications of enteric fever include intestinal bleeding, bowel perforation, pancreatitis, and cholecystitis. We encountered a case of lower gastrointestinal bleeding (hematochezia) as a complication of enteric fever. A 35-year-old male patient presented to Aster CMI hospital, India, with an intermittent fever of 2-week duration associated with dry cough, loss of appetite, abdominal pain, and generalized body weakness. Four days after admission, he experienced three episodes of lower gastrointestinal bleeding. Upon physical examination, he was hemodynamically stable and had a high-grade fever, mild hepatomegaly, tipped splenomegaly, and lower abdominal tenderness. Blood culture grew . Abdominal ultrasound showed ileocolonic thickening with enlarged mesenteric lymph nodes. Abdominal computed tomography scan displayed enlarged mesenteric lymph nodes with surrounding fat strands. A colonoscopy revealed multiple shallow, punched-out, and punctate ileocolonic ulcerative lesions, with stigmata of active bleeding at caecal ulcers. Colonoscopy-guided biopsy suggested multifocal active colitis favoring infective etiology. Diagnosis of blood culture-confirmed enteric ulcer was made. He was treated with ceftriaxone 1 g iv twice daily for 10 days and rehydrated with intravenous fluids. Adrenaline injection was done at the site of bleeding ulcers, and hemostasis was secured. Other additional medications were antipyretics, anti-emetics, multivitamins, and proton pump inhibitors. He was fever-free on the third day of admission and discharged after 10 days of hospital stay. He was appointed to follow-up clinic after a week. He was completely healthy on the day of the first follow-up clinic visit and planned to resume his duties. Enteric fever remains a common public health problem in most developing countries. Early suspicion and prompt institution of appropriate antibiotics are crucial in the reduction of systemic and local complications of enteric fever. Since gastrointestinal complications of enteric fever are less often encountered in the antibiotic era, clinicians should be cognizant of an enteric ulcer as a cause of lower gastrointestinal bleeding.

Mycobacterium avium complex (MAC) is often observed in immunocompromised individuals. However, when pulmonary MAC infection occurs in immunocompetent individuals, particularly elderly females, characteristically involving the middle lobe and lingula lobe of the lung, it is known as Lady Windermere syndrome (LWS). A 64-year-old female patient with no significant comorbidities presented with a history of low-grade intermittent fever and dry cough for one-month duration complicated with hemoptysis for two days. Her initial investigations and imaging were negative, except for the high-resolution CT (HRCT) finding of bronchiectasis involving the middle lobe and lingula lobe suggestive of MAC infection, which was further confirmed by positive sputum culture for MAC. LWS is a condition that is rarely encountered in clinical settings and seldom described in the literature. Especially in resource-limited settings, arriving at a diagnosis is further hindered by the scarce availability of advanced imaging such as HRCT. In clinical settings where pulmonary tuberculosis is endemic, the differentiation of the two conditions is of paramount importance as the treatment regimens for the two conditions are quite different.

Inflammatory myofibroblastic tumors (IMTs) of the lung are a rare type of mesenchymal tumors that tend to occur more in the lungs of children. They are extremely rare in adults. IMTs require extensive pulmonary resection because they are commonly locally invasive. The key to preventing recurrence is complete resection, and the prognosis is excellent after surgery. We report a case of a patient with an inflammatory pseudotumor of the lung. The patient is a 27-year-old female who presented with a dry cough. A chest radiograph and computed tomography showed a lesion in the left main bronchus and near-total left lung collapse. As surgery was necessary to establish the diagnosis, left pneumonectomy was performed followed by a histological examination of the surgical specimen which confirmed inflammatory pseudotumor.

BACKGROUND
The coronavirus disease 2019 (COVID-19) pandemic, caused by the SARS-CoV-2 virus, has had far-reaching implications beyond the respiratory system. Mounting evidence suggests that COVID-19 can impact various organ systems, including the eyes. This study aimed to elucidate the prevalence, characteristics, and clinical implications of ophthalmic manifestations in patients diagnosed with COVID-19.
METHODS
This retrospective study analyzed data from electronic medical records of adult patients hospitalized with COVID-19 between March 1, 2020, and December 31, 2020, at a large tertiary academic medical center. Ophthalmic manifestations, including conjunctivitis, dry eye symptoms, ocular pain, epiphora, ocular redness, and visual disturbances, were identified and examined for their prevalence, onset, duration, and associations with COVID-19 severity and systemic symptoms.
RESULTS
Among 342 patients included in the study, 106 (31.0%) experienced at least one ophthalmic manifestation during their COVID-19 illness. Conjunctivitis was the most common manifestation in 62 patients (18.1%), followed by dry eye symptoms in 38 patients (11.1%), ocular pain/discomfort in 27 patients (7.9%), epiphora in 19 patients (5.6%), ocular redness in 14 patients (4.1%), and visual disturbances in nine patients (2.6%). Ophthalmic manifestations were significantly associated with severe COVID-19 illness (42.9% vs. 26.7%, p = 0.003) and the presence of systemic symptoms such as fever, cough, and dyspnea. The median time of onset was six days, and the median duration was 10 days.
CONCLUSIONS
Ophthalmic manifestations are prevalent in COVID-19 patients, particularly in those with severe illness and systemic symptoms. The study highlights the importance of recognizing and managing ocular symptoms in affected individuals and underscores the multifaceted nature of COVID-19, necessitating interdisciplinary collaboration for comprehensive patient care.

This case study presents a rare occurrence of acute respiratory failure in a 17-year-old male diagnosed with common variable immunodeficiency (CVID) and granulomatous lymphocytic interstitial lung disease (GLILD), which typically have a gradual onset. The patient initially exhibited nonspecific symptoms such as dry cough and fever but quickly progressed to severe respiratory failure despite conventional treatments. Imaging showed extensive lung abnormalities, and blood tests revealed significantly low immunoglobulin levels, indicating an underlying immunodeficiency. Treatment with high-dose steroids and immunoglobulin replacement therapy resulted in a rapid and remarkable recovery of lung function. Lung biopsies confirmed the dual diagnoses of CVID and GLILD, emphasizing the challenge of diagnosing and managing GLILD in CVID patients. This case underscores the importance of early and aggressive intervention in improving outcomes for GLILD patients with acute respiratory distress.

Here, we report a case of non-Hodgkin's lymphoma in a 21-year-old man who presented with symptoms of gastric discomfort, hematemesis, breathlessness, dry cough, chest pain, loss of appetite, and weight loss. He had a history of pleural effusion and was previously diagnosed with tuberculosis. Further investigations revealed a mediastinal mass. A biopsy confirmed non-Hodgkin's lymphoma and ruled out thymoma. The patient underwent therapeutic thoracentesis for symptomatic relief and was started on chemotherapy. The prognosis of T-cell lymphoblastic lymphoma (T-LBL) is generally poorer compared to B-cell lymphoblastic lymphoma (B-LBL). T-LBL commonly presents with a mediastinal mass and pleural effusion. Imaging techniques like computed tomography (CT) help evaluate the extent and characteristics of the tumor. Prognostic factors for T-LBL include age, pleural effusion, and extranodal involvement. Molecular characterization is important in determining prognosis and treatment options. 18F-FDG imaging can assist in determining the extent of the tumor, staging, and assessment of response to treatment. Overall, lymphoblastic lymphoma is a rare entity, and T-LBL accounts for a small percentage of all lymphomas. Before the start of definitive chemotherapy, during the evaluation, the patient was started on steroid therapy for symptomatic management, following which regression in the size of the mediastinal tumor was noted.

Supportive Care in Cancer : Official... May 2024To identify symptom clusters (SCs) in patients with lung cancer who are undergoing initial chemotherapy and to identify the sentinel symptoms of each SC.
PURPOSE
To identify symptom clusters (SCs) in patients with lung cancer who are undergoing initial chemotherapy and to identify the sentinel symptoms of each SC.
METHODS
A convenience sampling method was used to recruit patients with lung cancer who were undergoing their initial chemotherapy treatment. Patient information was collected using the General Demographic Questionnaire, MD Anderson Symptom Inventory (including the lung cancer module) and a schedule documenting the initial occurrence of symptoms. The Walktrap algorithm was employed to identify SCs, while sentinel symptoms within each SC were identified using the Apriori algorithm in conjunction with the initial occurrence time of symptoms.
RESULTS
A total of 169 patients with lung cancer participated in this study, and four SCs were identified: the psychological SC (difficulty remembering, sadness, dry mouth, numbness or tingling, and distress), somatic SC (pain, fatigue, sleep disturbance, and drowsiness), respiratory SC (coughing, expectoration, chest tightness, and shortness of breath), and digestive SC (nausea, poor appetite, constipation, vomiting, and weight loss). Sadness, fatigue, and coughing were identified as sentinel symptoms of the psychological, somatic, and respiratory SCs, respectively. However, no sentinel symptom was identified for the digestive SC.
CONCLUSION
Patients with lung cancer who are undergoing chemotherapy encounter a spectrum of symptoms, often presenting as SCs. The sentinel symptom of each SC emerges earlier than the other symptoms and is characterized by its sensitivity, significance, and driving force. It serves as a vital indicator of the SC and assumes a sentry role. Targeting sentinel symptoms might be a promising strategy for determining the optimal timing of interventions and for mitigating or decelerating the progression of the other symptoms within the SC.
