Prolonged air leak (PAL) represents the most commonly encountered complication following pulmonary resection. This review aims to show the role of autologous blood pleurodesis (ABPP) in the management of PAL. A search was conducted on the Web of Science, PubMed, MEDLINE, and Google Scholar for English-language articles until September 15, 2023, with titles containing the related phrase “autologous blood patch pleurodesis (ABPP), and prolonged air leaks.” Included studies comprised four randomised controlled trials, ten cohort studies, a case series, and nine case reports from various countries. Patients undergoing ABPP had a mean age of 52.7 years. Autologous blood volumes for pleurodesis varied (50 mL to 250 mL). Approximately 73.8% of cases responded to ABPP in 1 to 30 days (mean 3.75 days), and in-hospital complications were infrequent (3.9%). Follow-up durations post pleurodesis were up to 20 months. The evidence presented in this systematic review supports the role of ABPP as an effective and safe intervention for managing PAL, particularly after pulmonary resection.

Introduction Sarcoidosis involving the thyroid gland is an exceedingly rare condition characterized by non-necrotizing and non-caseating granuloma. This study represents a case of thyroid sarcoidosis in an elderly female.Case report A 62-year-old female presented with anterior neck swelling associated with difficulties in breathing and swallowing for six months. Physical examination revealed an enlarged, firm, and non-tender thyroid gland. Thyroid function tests were normal, with a high level of angiotensin-converting enzyme. A neck ultrasound revealed nodules in both thyroid lobes and bilateral cervical lymphadenopathies. The patient underwent a total thyroidectomy and lymph node excision. Histopathological examination of the specimen showed features suggestive of thyroid sarcoidosis.Conclusion Sarcoidosis involving the thyroid gland is a rare finding, and its diagnosis necessitates the exclusion of other potential explanations for similar symptoms. Surgery becomes necessary when there are compression symptoms or a risk of malignancy.

Spindle epithelial tumor with thymus-like differentiation (SETTLE) is a rare benign lesion characterized by the presence of spindle and epithelioid cells and features resembling thymic tissue. A 35-year-old asymptomatic female with a history of two cesarean sections and a positive family history of breast cancer underwent a thyroid checkup. Clinical examination revealed a normal thyroid gland, while diagnostic tests indicated a solid hypoechoic nodule in the right lower parathyroid gland, which was confirmed as SETTLE after surgical resection was performed, leading to an uneventful postoperative period. The patient, discharged on the first postoperative day, underwent comprehensive follow-up and oncology referral for risk stratification. In the literature review of nine cases of SETTLE (seven male, two female), age (8–70 years), past medical and surgical history of the majority is not available, most of them presented with painless and slowly enlarging mass in the neck, on laboratory examination most of the cases had test results within the normal range, ultrasound (U/S) and computed tomography (CT) Scan are preferred imaging modality, most of the patient had undergone surgical resection, histopathological examination showed SETTLE after management more than half were disease free. SETTLE is a rare tumor with ∼50 reported cases worldwide and a single case report that involves parathyroid glands. It can be asymptomatic or present as a mass. Besides the necessity of surgical resection, long-term follow-up is mandatory.

Introduction Hemangiomas are benign vascular lesions. The complicated hemangiomas that are causing significant functional or cosmetic problems need surgical excision. This paper presents a novel technique of reconstruction using surgical mesh after removal of a facial hemangioma.Case report A 50-year-old male patient presented with right cheek swelling for more than 40 years causing disproportion of the face. A flap was raised by a nasolabial linear incision, then a 4*2 cm surgical mesh was put in, and the wound closed cosmetically. The excised tissue was sent for histopathological examinations and the results confirmed hemangioma. After more than two years follow up, the patient’s face was symmetrical with normal facial contour.Conclusion The application of surgical mesh for patients who seek functional and cosmetic improvements after hemangioma removal is a constructive method that gives the desired outcome for the patient.

Abstract Introduction To date, only a limited number of case reports have documented the co-occurrence of PNS and melanocytic nevus in the medical literature. This study aims to report an exceptionally rare case of posterior chest wall PNS in conjunction with a melanocytic nevus. Case presentation A 46-year-old female presented with a long-standing black lesion on her left upper posterior chest wall, that had become painful in the two months prior to presentation. There was a painful, dark blue, non-erythematous, and non-tender nodule on the left upper posterior chest wall. Based on the patient’s desire for cosmetic purposes, the lesion was excised totally with primary closure under local anaesthesia. Histopathological examination revealed intradermal melanocytic nevus with inflamed pilonidal sinus. Discussion The rarity of posterior chest wall PNS associated with nevi poses unique diagnostic and therapeutic challenges for clinicians. The distinct anatomical location, different from the conventional region, and the rare association between the two conditions may delay accurate diagnosis and result in mismanagement or inappropriate interventions. Conclusion The posterior chest wall PNS is another type of atypical PNS that is extremely rare. The association between PNS and blue nevus is a fascinating medical finding that deserves further investigation.

Machine learning (ML) and deep learning (DL) techniques have demonstrated significant potential in the development of effective intrusion detection systems. This study presents a systematic review of the utilization of ML, DL, optimization algorithms, and datasets in intrusion detection research from 2018 to 2023. We devised a comprehensive search strategy to identify relevant studies from scientific databases. After screening 393 papers meeting the inclusion criteria, we extracted and analyzed key information using bibliometric analysis techniques. The findings reveal increasing publication trends in this research domain and identify frequently used algorithms, with convolutional neural networks, support vector machines, decision trees, and genetic algorithms emerging as the top methods. The review also discusses the challenges and limitations of current techniques, providing a structured synthesis of the state-of-the-art to guide future intrusion detection research.

Lingual osteoma, a rare, benign bone tumor that primarily affects the posterior tongue, can be difficult to diagnose. This study aims to report a case of osteoma affecting the tongue in a 17-year-old female. The patient had a foreign body sensation and a progressively growing lesion for 3 years and underwent clinical examination and diagnostic procedures. A well-defined, smooth-surfaced, white mass was discovered in the posterior third of the tongue. The 1.5 × 1 × 0.4 cm mass was completely excised under local anesthesia and histopathologically confirmed as a benign lingual osteoma. The 2-month post-operative outcome was uneventful. The rarity of lingual osteoma, as well as the fact that it is often asymptomatic, makes diagnosis difficult. The diagnosis entails a proper clinical examination, imaging studies, and histopathological analysis. Surgical intervention, primarily aimed at complete excision while preserving tongue function, remains the primary treatment option. Successful excision entails educating healthcare professionals about this rare benign bony tumor to ensure the best possible patient outcomes.

Objective The incidence of thyroglossal duct diseases in the general population is about 7%. We aimed to demonstrate the clinical presentations and management of thyroglossal duct diseases. Methods We conducted a retrospective review of all patients who underwent surgery for histopathologically confirmed thyroglossal duct cyst, sinus, or fistula at a single center. Results A total of 151 cases were included in this study. There were more female patients (87, 58%) than male patients (64, 42%). The patients’ ages ranged from 1 to 63 years old. The most prevalent complaint was painless upper midline neck swelling (93.3%). Most cases were diagnosed as thyroglossal duct cysts (137, 90.7%). Six cases (4%) were associated with carcinoma. All the cases were managed using the modified Sistrunk procedure. There were no procedure-related complications, and five cases of recurrence. Conclusions Although thyroglossal duct cyst is the most common neck anomaly in children, it may also present with various characteristics later in life. This condition can be managed successfully without complications and with a low recurrence rate.

Objective This study was performed to report and analyze the prevalence of permanent facial nerve paralysis following parotidectomy for various benign and malignant lesions in a single center. Methods This single-center retrospective study included all patients who underwent parotidectomy (total and superficial) for benign and malignant tumors and chronic inflammatory diseases during a 6-year period. Patients who had previously undergone an operation of the parotid gland and those with preoperative facial weakness were excluded. Results The study included 127 patients ranging in age from 14 to 83 years (median, 45.89 years). Most patients were female (n = 83, 65.4%). The most prevalent procedure was superficial parotidectomy (n = 117, 92.1%), followed by total parotidectomy (n = 6, 4.7%). The average operative duration was 138 minutes (range, 80–400 minutes). Histopathology revealed that 109 (85.8%) patients had benign tumors, 14 (11.0%) had malignant tumors, and 4 (3.1%) had chronic sialadenitis. Only two patients sustained an injury to the cervical branch of the facial nerve. Conclusion In this single-center experience of parotid surgery, the rates of transient and permanent facial paralysis were acceptably low at 9.0% and 1.6%, respectively, for all pathologies.

Copper -graphite composites are widely used in a great number of engineering applicationssuch as brushes, switches, sliding bearings, self-lubricating bearings, etc. due to their goodthermal and electrical conductivity and excellent tribological properties as compared with otherstructural materials. There are ongoing attempts in manufacturing copper composites with betterproperties to enhance their efficiency and increase their effective life. Present research aims to prepare hybrid 95wt.% copper –5wt.% graphite composites reinforced with yttria and tin particles by powder metallurgy technique and to study their effects on mechanical and physical properties of the prepared composites. Powder mixture was mixed by ball mill mixer at 100rpm for 120min with (5/1) balls to powder ratio. The powder mixture was cold pressed at 700MPa for 30sec, followed by sintering at 900 ?C for one hour. In the first stage, Yttria(Y2O3) was added with (2, 4, 6, 8, 10) wt% to pure copper (Cu) and to (95%Cu-5%Gr) matrices. Typical composite of this stage was ((95%Cu-5%Gr)-4%Y2O3. In the second stage, tin (Sn) was added with (2, 4, 6, 8, 10) wt% to pure copper and((95%Cu-5%Gr)-4%Y2O3 matrices. Typical composite of this stage was ((95%Cu-5%Gr)-4%Y2O3)-6%Sn. The results showed that hardness and true porosity of the composites increases with increasing yttria content. On the other hand both thermal and electrical conductivity of the composites decreases with increasing yttria content. It was also found that (95 wt.% Cu- 5 wt.% Gr) – Y2O3 composites have always lower wear rate than plain Cu-Y2O3 composites.
