Review
Muco-obstructive lung disease is a new classification under the diseases of respiratory tract. A lot of discussion is still going on regarding this new group of diseases. It is characterised by obstruction of the respiratory tract with a thick mucin layer. Usually in normal individuals, the mucus is swept out of the respiratory system while coughing in the form of sputum or phlegm, but if the consistency of the mucus is thick, or the amount is heavy or there is a certain defect in the ciliary function of the respiratory tract, the mucus is not cleared and it gets accumulated in the lungs alveoli, therefore blocking it. The mucus trapped in the distal airways cannot be cleared by coughing therefore forming a layer in the alveoli and bronchioles. Long-standing condition causes inflammation and infection. This new group of diseases specifically includes chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), primary ciliary dyskinesia (PCD) and non-cystic fibrosis bronchiectasis (NCFB). Asthma, although an obstructive disease of the lung, is not particularly included under muco-obstructive lung disease. The major symptoms with which these diseases present are sputum production, chronic cough and acute exacerbations of the condition. The mucus adheres to the lung parenchyma causing airway obstruction and hyperinflation. In this article, we will see how muco-obstructive lung diseases affect the normal physiology of the respiratory system and how is it different from other obstructive and restrictive lung diseases. We will individually look into all the four conditions that come under the category of muco-obstructive lung diseases.

Review
INTRODUCTION
Ultrasound has been nicknamed "the surgeon's stethoscope". The advantages of laparoscopic ultrasound beyond a substitute for the sense of touch are considerable, especially for robotic surgery. Being able to see through parenchyma and into vascular structures enables to avoid unnecessary dissection by providing a thorough assessment at every stage without the need for contrast media or ionising radiation. The limitations of restricted angulation and access within the abdominal cavity during laparoscopy can be overcome by robotic handling of miniaturised ultrasound probes and the use of various and specific frequencies will meet tissue- and organ-specific characteristics. The aim of this systematic review was to assess the reported applications of intraoperative ultrasound-guided robotic surgery and to outline future perspectives.
METHODS
The study adhered to the PRISMA guidelines. PubMed, Google Scholar, ScienceDirect and ClinicalTrials.gov were searched up to October 2023. Manuscripts reporting data on ultrasound-guided robotic procedures were included in the qualitative analysis.
RESULTS
20 studies met the inclusion criteria. The majority (53%) were related to the field of general surgery during liver, pancreas, spleen, gallbladder/bile duct, vascular and rectal surgery. This was followed by other fields of oncological surgery (42%) including urology, lung surgery, and retroperitoneal lymphadenectomy for metastases. Among the studies, ten (53%) focused on locating tumoral lesions and defining resection margins, four (15%) were designed to test the feasibility of robotic ultrasound-guided surgery, while two (10.5%) aimed to compare robotic and laparoscopic ultrasound probes. Additionally two studies (10.5%) evaluated the robotic drop-in probe one (5%) assessed the hepatic tissue consistency and another one (5%) aimed to visualize the blood flow in the splenic artery.
CONCLUSION
The advantages of robotic instrumentation, including ergonomics, dexterity, and precision of movements, are of relevance for robotic intraoperative ultrasound (RIOUS). The present systematic review demonstrates the virtue of RIOUS to support surgeons and potentially reduce minimally invasive procedure times.

Review
BACKGROUND AND PURPOSE
Parotid gland lymphoma (PGL) is a rare and challenging diagnosis. Different lymphomas can develop in the parotid gland, with the most common being the mucosa-associated lymphoid tissue (MALT) lymphoma, which originates directly from the glandular parenchyma. Other histologic subtypes arise from both intraglandular and extraglandular parotid lymph nodes. A consensus on diagnosis and treatment of PGL is still lacking, and published data is scarce and heterogeneous.
METHODS
We performed a systematic review of the literature, including studies published after 2001, when the WHO classification of lymphoid tumours was introduced.
RESULTS
Twenty retrospective studies were included in the analyses, eight of which focused exclusively on MALT lymphomas. Final analysis included 612 cases of PGL, with a 1.68:1 F/M ratio. MALT lymphoma was the most common histology, followed by follicular and diffuse large B-cell lymphoma. Most cases were low stages (IE/IIE acc. Ann Arbour, 76.5%) and only 10% of patients presented with symptoms, most commonly pain (4.8%) and B symptoms (2.2%). A high prevalence of associated autoimmune diseases was found, particularly Sjögren's syndrome, that affected up to 70% of patients with MALT lymphoma. In most cases diagnosis was achieved through parotidectomy (57.5%), or open biopsy (31.2%). Treatment strategies were either surgical, non-surgical or a combination of modalities. Surgery as a single-modality treatment was reported in about 20% of patients, supposing it might be a valuable option for selected patients.
CONCLUSIONS
Our review showed that the diagnosis and treatment of PGLs is far from being standardized and needs further, more homogeneous reports to reach consensus.

Review
BACKGROUND
Interstitial lung diseases (ILDs) cause fibrosis of lung parenchyma, leading to impaired quality of life, dyspnea, and functional decline. Individuals with ILD experience a high prevalence of anxiety and depression. Recent research has demonstrated pulmonary rehabilitation (PR) alleviates symptoms of anxiety and depression in those with COPD.
RESEARCH QUESTION
What is the influence of PR on symptoms of anxiety and depression in individuals with ILD?
STUDY DESIGN
We conducted a PRISMA-2020-compliant systematic review of randomized controlled trials (RCTs) investigating PR's effect on anxiety and depression in patients with ILD. We searched MEDLINE, EMBASE, Cochrane, and PsycINFO from inception until April 3, 2023. A narrative synthesis was conducted where a quantitative approach was not feasible.
RESULTS
Five RCTs (n = 281) were included. Idiopathic pulmonary fibrosis (IPF) was the most common type of ILD (k = 3). One study reported clinically-significant improvements in symptoms of anxiety among patients with IPF, and two studies for symptoms of depression among patients with sarcoidosis. Dropout rates were similar between intervention and control groups. All studies were at a high risk of bias.
INTERPRETATION
Pulmonary rehabilitation is not detrimental to anxiety or depression for patients with ILD, and may improve symptoms of anxiety in IPF and depression in sarcoidosis. However, no conclusion can be drawn from available evidence, which is limited by heterogeneous populations/interventions, sample sizes and unexpectedly low prevalences of clinically-significant anxiety or depression. Further adequately powered RCTs that focus on anxiety and depressive symptoms as primary outcomes are needed.

Review
Intracerebral hemorrhage (ICH) is a stroke subtype characterized by non-traumatic rupture of blood vessels in the brain, resulting in blood pooling in the brain parenchyma. Despite its lower incidence than ischemic stroke, ICH remains a significant contributor to stroke-related mortality, and most survivors experience poor outcomes that significantly impact their quality of life. ICH has been accompanied by various complex pathological damage, including mechanical damage of brain tissue, hematoma mass effect, and then leads to inflammatory response, thrombin activation, erythrocyte lysis, excitatory amino acid toxicity, complement activation, and other pathological changes. Accumulating evidence has demonstrated that activation of complement cascade occurs in the early stage of brain injury, and the excessive complement activation after ICH will affect the occurrence of secondary brain injury (SBI) through multiple complex pathological processes, aggravating brain edema, and pathological brain injury. Therefore, the review summarized the pathological mechanisms of brain injury after ICH, specifically the complement role in ICH, and its related pathological mechanisms, to comprehensively understand the specific mechanism of different complements at different stages after ICH. Furthermore, we systematically reviewed the current state of complement-targeted therapies for ICH, providing a reference and basis for future clinical transformation of complement-targeted therapy for ICH.

Review
BACKGROUND
Hemostasis is crucial in preventing hemorrhage during cranial neurosurgical procedures and maintaining visualization of the surgical field. There is significant variation in the availability of hemostatic methods across different settings and hemostatic techniques are being continuously developed over the decades of practicing neurosurgery. The aim of this article is to provide an outline of the potential methods to achieve hemostasis based on the sequential operative anatomy of a cranial operation.
METHODS
A systematic review was conducted following the PRISMA guidelines. The PubMed database was searched from inception of the database to July 18, 2023. A total of 64 studies were identified fulfilling predefined inclusion criteria, and the risk of bias was assessed using the Joanna Briggs Institute checklists.
RESULTS
Seventy-one hemostatic agents, techniques, tools, and devices were identified, which were then categorized according to the operative phase for which they are indicated. Nine operative anatomic targets were addressed in the sequence in which they are involved during a cranial procedure. For each anatomic target, the following number of hemostatic techniques/agents were identified: 11 for scalp, 3 for periosteum, 10 for skull bone, 11 for dura mater, 9 for venous sinuses, 5 for arteries, 6 for veins, 12 for brain parenchyma, and 4 for cerebral ventricles.
CONCLUSIONS
Depending on the phase of the surgery and the anatomic structure involved, the selection of the appropriate hemostatic method is determined by the source of bleeding. Surgeon awareness of all the potential techniques that can be applied to achieve hemostasis is paramount, especially when faced with operative nuances and difficult-to-control bleeding during cranial neurosurgical procedures.

Meta-Analysis Review
BACKGROUND
Pancreatic benign, cystic, and neuroendocrine neoplasms are increasingly detected and recommended for surgical treatment. In multiorgan resection pancreatoduodenectomy or parenchyma-sparing, local extirpation is a challenge for decision-making regarding surgery-related early and late postoperative morbidity.
METHODS
PubMed, Embase, and Cochrane Libraries were searched for studies reporting early surgery-related complications following pancreatoduodenectomy (PD) and duodenum-preserving total (DPPHRt) or partial (DPPHRp) pancreatic head resection for benign tumors. Thirty-four cohort studies comprising data from 1099 patients were analyzed. In total, 654 patients underwent DPPHR and 445 patients PD for benign tumors. This review and meta-analysis does not need ethical approval.
RESULTS
Comparing DPPHRt and PD, the need for blood transfusion (OR 0.20, 95% CI 0.10-0.41, p<0.01), re-intervention for serious surgery-related complications (OR 0.48, 95% CI 0.31-0.73, p<0.001), and re-operation for severe complications (OR 0.50, 95% CI 0.26-0.95, p=0.04) were significantly less frequent following DPPHRt. Pancreatic fistula B+C (19.0 to 15.3%, p=0.99) and biliary fistula (6.3 to 4.3%; p=0.33) were in the same range following PD and DPPHRt. In-hospital mortality after DPPHRt was one of 350 patients (0.28%) and after PD eight of 445 patients (1.79%) (OR 0.32, 95% CI 0.10-1.09, p=0.07). Following DPPHRp, there was no mortality among the 192 patients.
CONCLUSION
DPPHR for benign pancreatic tumors is associated with significantly fewer surgery-related, serious, and severe postoperative complications and lower in-hospital mortality compared to PD. Tailored use of DPPHRt or DPPHRp contributes to a reduction of surgery-related complications. DPPHR has the potential to replace PD for benign tumors and premalignant cystic and neuroendocrine neoplasms of the pancreatic head.

La Clinica Terapeutica 2023Splenosis is the presence of ectopic autotransplantation of splenic tissue in various compartments of the human body, occurring after rupture of the splenic parenchyma.
BACKGROUND
Splenosis is the presence of ectopic autotransplantation of splenic tissue in various compartments of the human body, occurring after rupture of the splenic parenchyma.
METHODS
A systematic PubMed and Scopus search was conducted.
RESULTS
The mean age of the patients was 51.7 years. The majority of patients were of female gender. An emergency presentation was noted in 30 out of 85 patients, having abdominal pain as main symptom. The principal reason for splenectomy were traffic accidents. The time span between splenectomy and the initial symptoms ranged between 1 and 57 years. The most frequent symptom at presentation of pelvic splenosis was abdominal pain. Almost a quarter of the included patients were without any symptom. Presence of extrapelvic splenosis was de-scripted in almost half of the included patients. With regards to the type of treatment provided, exploratory laparotomy, laparoscopic surgical exploration / laparoscopy, robotic removal of splenium and watchful waiting, were performed in 35 (41.2%), 32 (37.6%), 3 (3.5%) and 15 (16.3%) patients, respectively. No fatality was reported.
CONCLUSION
Pelvic splenosis is a rare clinical condition. It may mimic several clinical conditions and mislead diagnosis. The clinical history of splenectomy for trauma or different other reasons may es-tablish diagnosis and exclude other morbidities. Excision and complete removal of pelvic splenosis nodules is not always necessary and it depends on the clinical symptomatology. Careful imaging and precise assessment with the assistance of nuclear medicine may lead to correct diagnosis and avoid unnecessary surgical interventions.

Review
BACKGROUND
Lobectomy is currently the advised resection for symptomatic congenital lung abnormalities (CLA). Sublobar surgery is suggested as an alternative that enables to conserve healthy lung parenchyma. This systematic review aims to explore the outcomes of sublobar surgery in CLA patients as well as the corresponding surgical terminology and techniques.
METHODS
A systematic literature search was performed in adherence to PRISMA-P guidelines. The target population consists of children undergoing sublobar pulmonary resection for CLA. All studies were independently assessed by two reviewers, and evaluated by a third reviewer in case of disagreement.
RESULTS
The literature search yielded 901 studies of which 18 studies were included, comprising 1167 cases. The median chest tube insertion duration was 3.6 days (range 2.0-6.9 days), the median hospital admission was 4.9 days (range 2.0-14.5 days), and residual disease was diagnosed in 2% - leading to re-operation in 70%. The median incidence of postoperative complications was 15% (range 0-67%). Follow-up imaging was standard-of-care in 2/3 of studies. Due to the absence of standardised terminology, operative details and specification of resection type did not typically relate between studies.
CONCLUSIONS
Sublobar resection of CLA lesions could be a viable alternative to lobectomy in certain cases, with the advantage of conserving healthy lung parenchyma. Peri- and postoperative complications are comparable with those reported for conventional lobectomy. The incidence of residual disease following sublobar surgery appears to be lower than commonly stated. To improve comparability between studies, we recommend reporting perioperative characteristics in a structured format.

Review
AIM
Primary paragangliomas (PGs) are extra-adrenal neuroendocrine tumours that are extremely rare. Multiple lesions in the central nervous system raise suspicion of a metastatic process. Lack of consensus on their management warrants the categorization of existing literature to evaluate management options.
METHODS
A systematic review of the medical literature on paraganglioma within the cranial vault was completed in accordance with PRISMA guidelines using the Medline database. Tumour physical measures, management parameters, and immunohistochemistry of all documented cases of primary and secondary paraganglioma within the cranial vault were descriptively compared. This review was augmented by comparison with our centre's case of a 48-year-old man diagnosed with metastatic PG originating in the cauda equina and seeding in the cerebellum. Histological parameters within the literature was also established.
RESULTS
The systematic literature review yielded published 52 papers. Most prevalent primary intracranial PGs (n = 37) were in the sellar region (78%, n = 23) and the cerebellum (21%, n = 6). The highest progression free survival was seen in primary sellar PGs (87.5% by 34.5 months) and cerebellar PGs (100% by 35.7 months) when treated with adjuvant radiotherapy with subtotal resection or gross total resection, respectively. Contrasting, the most frequent intracranial PGs metastases (n = 15) occurred in the cerebellum (36%, n = 6), and the cerebral parenchyma (29%, n = 4). Their recurrence rate was between 4 and 10% and these metastasized PG in the cerebellum are slow growing (8.9 years, range: 3-22 years). Adjuvant radiotherapy with Gross Total Resection resulted in the optimum progression-free survival (100% up to 48 months) for the patient with PGs metastasis to the cerebellum.
CONCLUSION
Metastatic PGs tend to be slow-growing and are clinically silent tumours. Diagnosed patients should undergo regular surveillance neuroradiological assessment, regardless of symptomatology, for metastases along the complete neural axis. We recommend operative management with GTR and adjunct RT in these patients.
