Review
BACKGROUND
Pulmonary arteriovenous malformation (PAVM), also known as pulmonary arteriovenous fistula, is a rare vascular developmental anomaly. Most cases of PAVM are associated with hereditary hemorrhagic telangiectasia (HHT). Hemothorax associated with PAVM is even rarer, and management concerning this complication still challenges.
CASE PRESENTATION
A 55-year-old man with sudden onset of dyspnea and chest pain was admitted to our hospital. He had a medical history of epistaxis, intraperitoneal germ cell tumor and PAVM. Chest unenhanced CT revealed the left-sided pleural effusion together with partial passive atelectasis and gradual increase at the interval of six days. Diagnostic thoracocentesis further revealed hemorrhagic effusion. CT angiography (CTA) showed tortuously dilated lumen of the left lower pulmonary artery and PAVM with the formation of aneurysm. Due to his family's refusal of surgery, the patient underwent transcatheter embolization therapy. However, the left pleural effusion did not significantly reduce and there was a slow drop in hemoglobin value even after interventional treatment, indicating the possibility of ongoing active bleeding. Eventually, the patient received lobectomy of the left lower lobe with a satisfactory outcome.
CONCLUSIONS
Massive hemothorax resulting from PAVM rupture into the pleural space can lead to fatal outcomes. CTA can accurately diagnose this pathologic condition. Transcatheter embolization is frequently used in the treatment of PAVM, but it may be challenging to achieve the desirable effect in patients with hemothorax. Combined with our case and literature review, direct radical surgery can lead to a successful outcome when PAVM complicated with hemothorax and a large diameter of the draining vein.

Review
BACKGROUND
Congenital myasthenic syndromes (CMS) are among the most challenging differential diagnoses in the neuromuscular domain, consisting of diverse genotypes and phenotypes. A mutation in the Docking Protein 7 (Dok-7) is a common cause of CMS. DOK7 CMS requires different treatment than other CMS types. Regarding DOK7's special considerations and challenges ahead of neurologists, we describe seven DOK7 patients and evaluate their response to treatment.
METHODS
The authors visited these patients in the neuromuscular clinics of Tehran and Kerman Universities of Medical Sciences Hospitals. They diagnosed these patients based on clinical findings and neurophysiological studies, which Whole Exome Sequencing confirmed. For each patient, we tried unique medications and recorded the clinical response.
RESULTS
The symptoms started from birth to as late as the age of 33, with the mean age of onset being 12.5. Common symptoms were: Limb-girdle weakness in 6, fluctuating symptoms in 5, ptosis in 4, bifacial weakness in 3, reduced extraocular movement in 3, bulbar symptoms in 2 and dyspnea in 2 3-Hz RNS was decremental in 5 out of 6 patients. Salbutamol was the most effective. c.1124_1127dupTGCC is the most common variant; three patients had this variant.
CONCLUSION
We strongly recommend that neurologists consider CMS in patients with these symptoms and a similar familial history. We recommend prescribing salbutamol as the first-choice treatment option for DOK7 patients.

The Journal of Allergy and Clinical... Jun 2024Breathlessness is a disabling symptom, with complexity that is often under recognised and under treated in asthma.
BACKGROUND
Breathlessness is a disabling symptom, with complexity that is often under recognised and under treated in asthma.
OBJECTIVE
To highlight the burden of breathlessness in people with severe compared with mild-to-moderate asthma and identify psychophysiological correlates of breathlessness.
METHODS
This was a cross-sectional study of people with mild-to-severe asthma, who attended two in-person visits to complete a multidimensional assessment. The proportion of people with mild-to-moderate versus severe asthma who reported physically limiting breathlessness (modified Medical Research Council [mMRC] dyspnoea score ≥2) was compared. Psychophysiological factors associated with breathlessness in people with asthma were identified via a directed acyclic graph and explored with multivariate logistic regression to predict breathlessness.
RESULTS
144 participants were included, of which, 74 (51%) had mild-to-moderate asthma and 70 (49%) severe asthma. Participants were predominantly female (n=103, 72%) with a median (quartile 1, quartile 3) age of 63.4 (50.5,69.5) years and body mass index (BMI) of 31.3 (26.2, 36.0) kg/m. The proportion of people reporting mMRC ≥2 was significantly higher in those with severe- (n=37, 53%) compared with mild-to-moderate (n=21, 31%) asthma (p=0.013). Dyspnoea-12 Total (8.00 [4.75, 17.00] versus 5.00 [2.00, 11.00], p=0.037) score was also significantly higher in the severe asthma group. Significant predictors of physically limiting breathlessness were: BMI, asthma control, exercise capacity, and hyperventilation symptoms. Airflow limitation and type-2 inflammation were poor breathlessness predictors.
CONCLUSION
Over half of people with severe asthma experience physically limiting breathlessness despite treatment. Targeting psychophysiological factors, or traits, associated with breathlessness may help relieve this distressing symptom, which is of high priority to people with asthma.

OBJECTIVE
This study aims to investigate the impact of cohort management on illness perception, fear of disease progression, nutritional status, and quality of life among patients with lymphoma.
METHODS
A total of 128 cases of lymphoma patients admitted to Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, between April 2020 and November 2021 were included as research participants. The patients were randomly assigned to two groups: a 64-member control group and a 64-member observation group. The observation group received group management, while the control group received standard nursing care. Before and after the intervention, assessments were conducted to evaluate disease perception, fear of disease progression, nutritional status, and quality of life, with comparisons made between the two groups.
RESULTS
No clinically significant differences (P > .05) were observed between the two groups regarding gender, age, chemotherapy cycles, clinical stage, disease type, or other general characteristics. Disease awareness showed no significant disparity between groups pre-intervention (P > .05), but post-intervention, the observation group exhibited marked improvement (P < .05). Initially, fear of disease progression did not differ significantly between groups (P > .05), but post-intervention, the observation group demonstrated lower scores in total fear of disease progression, social, family, and physical health domains compared to the control group (P < .05). While nutritional status comparisons initially resulted in no significant differences (P > .05), levels of serum albumin, prealbumin, hemoglobin, lymphocytes, and ferritin were notably higher in the observation group post-intervention (P < .05). Quality of life assessments showed no significant disparity pre-intervention (P > .05); however, post-intervention, the observation group experienced significantly reduced dyspnea, insomnia, and appetite loss (P < .05).
CONCLUSION
Participation in cohort management interventions benefits lymphoma patients by enhancing emotional coping and improving nutritional health and quality of life.

INTRODUCTION
Pulmonary lymphangitis carcinomatosa is a rare and severe manifestation of metastatic disease that causes pulmonary symptoms and radiologic patterns similar to interstitial lung diseases.
CASE PRESENTATION
We report a case of a 78-year-old woman who presented to our department with insidiously developed symptoms of fatigue, dry cough, and severe dyspnea for 3 months. Chest radiography showed bilateral interstitial changes. On suspicion of interstitial lung disease, bronchoscopy and transbronchial cryobiopsy were carried out. Surprisingly, histopathological investigation revealed pulmonary lymphangitis carcinomatosa originating from primary breast adenocarcinoma.
CONCLUSION
To achieve an accurate diagnosis and prevent delay of initiation of proper treatment a thorough diagnostic approach is necessary. In case of doubt, biopsy should be performed to secure clarification. In this case report we discuss the diagnostic value of transbroncial cryobiopsy for this purpose.

SMARCA4-deficient undifferentiated thoracic tumor (SMARCA4-UT) is a rare malignant tumor characterized by inactivation of the gene and the presence of undifferentiated or rhabdoid morphology in the tissue. This tumor is highly invasive, typically diagnosed at advanced stages III or IV, and commonly involves thoracic structures, such as the mediastinum and chest wall. Reported cases are limited and treatment guidelines have not yet been established. Here, we present a rare case of surgically treated non-metastatic SMARCA4-UT. The patient presented with blood-tinged sputum, dyspnea, and a history of heavy smoking, and underwent surgery after preoperative evaluation ruled out contraindications. The tumor was successfully removed along with the relevant lymph nodes; analysis determined it to be stage IIB T3N0M0. No recurrence was detected at two months post-surgery. However, four months after surgery, the tumor recurred and invaded the adjacent ribs. The diagnosis, differential diagnosis, and treatment of SMARCA4-deficient undifferentiated lung tumors is considered. The combination of chemotherapy and immunotherapy has shown efficacy, and other treatments such as anti-angiogenic drugs, histone deacetylase inhibitors (HDACi), enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) inhibitors, and oxidative phosphorylation (OXPHOS) inhibitors may also be beneficial in treating SMARCA4-UT.

Midventricular obstruction (MVO) is a rare form of hypertrophic cardiomyopathy (HCM). While surgical treatment for HCM is among the most technically challenging cardiac operations for acquired disease, surgery for MVO is rarely reported. A 38-year-old man was admitted to our hospital with a cough and dyspnea. Transthoracic and transesophageal echography and computed tomography revealed extensive left ventricular hypertrophy, extending from the anteroseptal wall to the apex, and marked papillary muscle hypertrophy. We underwent septal myectomy via aortotomy (Morrow procedure) and apical surgery. Extended myectomy provides the best exposure to the hypertrophied septum and improves the functional status of patients.

Review
About 40 % of new-onset epilepsy is drug refractory. If epilepsy surgery is not an option or fails, vagal nerve stimulation (VNS) can be considered. VNS efficacy is reported as more than 50 % seizure frequency reduction in 50-56 % of patients. Features in the newer models offer additional treatment optimization possibilities. Side effects include hoarseness, cough, and dyspnoea. Caution is advised for patients with sleep apnoea or lung disease. VNS has specific limitations concerning MRI. This review presents an overview of VNS treatment in Denmark and discusses future challenges.

BACKGROUND
Thymic mucosa-associated lymphoid tissue (MALT) lymphoma is rare and is known to be associated with Sjögren's syndrome (SjS). SjS is rarely accompanied by serositis. Here, we describe the first case of postoperative cardiac tamponade and acute pleuritis in a patient with thymic MALT lymphoma associated with SjS.
CASE PRESENTATION
A 33-year-old woman with SjS presented with an anterior mediastinal mass on chest computed tomography, which was performed for further examination of the condition. Suspecting a thymic MALT lymphoma or thymic epithelial tumor, total thymectomy was performed. The mediastinal mass was histopathologically diagnosed as a thymic MALT lymphoma. The patient was discharged with a good postoperative course but visited the hospital 30 days after surgery for dyspnea. Cardiac tamponade was observed and drainage was performed. Four days after pericardial drainage, chest radiography revealed massive left pleural effusion, and thoracic drainage was performed. The patient was diagnosed with serositis associated with SjS and treated with methylprednisolone, which relieved cardiac tamponade and pleuritis.
CONCLUSIONS
Surgical invasion of thymic MALT lymphomas associated with SjS may cause serositis. Postoperative follow-up should be conducted, considering the possibility of cardiac tamponade or acute pleuritis due to serositis as postoperative complications.
