Zinc(Ⅱ) induced Alzheimer’s Disease (AD) prevention and suppressive progression with early, middle, and lately stages are elucidated, and subsequently zinc binding molecular mechanism on each Aβ peptide and Tau protein in progressing stages is clarified. Zinc homeostasis regulates MCI and AD prevention, in which ZnCl2 could prevent AD pathology by that zinc can reduce β-Amyloid (Aβ) and Tau proteins. Zinc transporters may allow the novel therapies that ZnT-6 functions to a likely site of Aβ generation. At AD progression with early stage, zinc-induced aggregation of Aβ peptides and tau hyperphosphorylation on amyloid and tau aggregation consider the involvement of environmental zinc in Aβ and tau pathology. Zinc can suppress spreading of the Aβ peptide and the Tau protein that elemental zinc 150 mg daily is showed to be evident for an improvement of memory, understanding, communication, and social contact in AD. Zinc induced middle stage AD progression is pathologically characterized by the deposition of Aβ plaques and hyperphosphorylated Tau Proteins (p-tau). Zinc Finger Proteins (ZNFs) regulate the accumulation of tau proteins to affect the Neurofibrillary Tangles (NFTs), resulting in the formation of NFTs, and can inhibit protein phosphatase, promoted abnormal phosphorylation of tau protein. Zinc(Ⅱ) can prevent heavy stage AD with pathological deposits of Senile Plaques (SPs) and NFTs that the tau-zinc interaction will help understanding the zinc-related tau regulation or aggregation processes in both physiological and pathological conditions. Zinc accelerates the fibrillization of human Tau and thereby increases Tau toxicity in neuronal cells with zinc exacerbated tauopathic deficits. Zinc induced toxic Reactive Oxygen Species (ROS) generation and hyperphosphorylated tau cause oxidative stress and neurotoxicity, leading to hyperphosphorylated tau damages. Zinc(Ⅱ) binding AD molecular mechanism on Aβ and Tau proteins is that Zn2+ ions which having Zn2+ ions-centered tetrahedral geometric coordination pattern and Zn-CysHis Ligands complexes with tetrahedral geometry formed, bind with Aβ and Tau proteins in each three AD progressing stages, causing Zn2+ ions-each stages protein complex formations and oxidative stress to Aβ and Tau protein cells, leading the Zn-CysHis Ligands complexes to molecular and apoptosis activities of synaptic cells.
阐明了锌(Ⅱ)对阿尔茨海默病（AD）早期、中期和晚期的预防和抑制作用，进而阐明了锌与Aβ肽和Tau蛋白在进展阶段的分子结合机制。锌平衡调控MCI和AD的预防，其中氯化锌可减少β-淀粉样蛋白（Aβ）和Tau蛋白，从而预防AD病变。锌转运体可使新型疗法ZnT-6作用于Aβ生成的可能部位。在AD进展的早期阶段，锌诱导的Aβ肽聚集以及淀粉样蛋白和tau聚集上的tau过度磷酸化认为环境中的锌参与了Aβ和tau的病理过程。锌能抑制 Aβ 肽和 Tau 蛋白的扩散，每天摄入 150 毫克元素锌对改善 AD 患者的记忆、理解、沟通和社会接触有明显作用。锌诱导的渐冻症中期进展的病理特征是 Aβ 斑块和高磷酸化 Tau 蛋白（p-tau）的沉积。锌指蛋白（ZNFs）能调节 tau 蛋白的积累，影响神经纤维缠结（NFTs），导致 NFTs 的形成，并能抑制蛋白磷酸酶，促进 tau 蛋白的异常磷酸化。锌（Ⅱ）能防止重度AD出现老年斑（SPs）和NFTs的病理沉积，tau-锌相互作用有助于理解生理和病理状态下与锌相关的tau调控或聚集过程。锌会加速人类 Tau 的纤维化，从而增加神经细胞中 Tau 的毒性，锌会加剧 Tau 病理缺陷。锌诱导的毒性活性氧（ROS）生成和高磷酸化tau会引起氧化应激和神经毒性，导致高磷酸化tau损伤。锌（Ⅱ）与 Aβ 和 Tau 蛋白的 AD 结合分子机制是，具有以 Zn2+ 离子为中心的四面体几何配位模式的 Zn2+ 离子与 Zn-CysHis 配体形成四面体几何复合物、与 AD 三个进展阶段中的 Aβ 蛋白和 Tau 蛋白结合，导致 Zn2+ 离子与各阶段蛋白形成复合物，并对 Aβ 蛋白和 Tau 蛋白细胞产生氧化应激，导致 Zn-CysHis 配体复合物对突触细胞产生分子和凋亡活性。

Introduction: Breast cancer is the leading cause of cancer in women with an estimated 2.3 million new cases worldwide and a high mortality rate. The incidence of breast cancer has been increasing worldwide in the past few years with a similar trend of escalation in Pakistan. The age-standardized incidence rate of breast cancer in Pakistan is 104 per one million and the mortality rate is 65 per one million population. Limited studies have been done to evaluate the diagnostic accuracy of combined mammography and ultrasound with BI-RADS scoring in the detection of breast cancer and positive predictive value of its morphological descriptors in Pakistan. Objective: Our study aims to determine the diagnostic accuracy of combined mammography and ultrasound in the detection of malignant breast lesions using BI-RADS classification taking histopathology as the gold standard and positive predictive value of its morphological descriptors. Materials and Methods: This was a retrospective, cross-sectional analysis. All the patients presented with breast-related symptoms and for screening in whom mammography with complimentary ultrasound was performed were included. Mammography protocol includes image acquisition in craniocaudal and mediolateral oblique views. On ultrasound, all quadrants of the breast, retroaerolar region, and axilla were assessed. Patient stratification was done based on the age, clinical symptoms, and positive malignant lesions on histopathology; and frequency and percentage were calculated. Sensitivity, Specificity, Positive Predictive Value (PPV), Negative Predictive Value (NPV), and diagnostic accuracy was calculated. PPV of individual morphological descriptors were also calculated. The association of various morphological descriptors with malignancy was analyzed using a chi-square chart. p-value of less than 0.05 was considered significant. Results: In 69 patients with suspicious imaging findings, 89.9% patients presented with breast lumps, 34.8% patients had pain, and 11.6% patients had nipple discharge. 8.7% had nipple retraction and 10.1% had skin changes. 52.2 % patients were post-menopausal and 46.1% patients were premenopausal. On histopathology, 88.4% patients had malignant disease and 11.5% were having benign lesions. The mean age of patients with malignant masses was 50.9 years+13.1 SD. No significant statical difference is noted between younger and older groups. The mean size of the malignant mass was 3.0 cm+1.8 SD. The sensitivity of combined mammogram and ultrasound was calculated to be 98.3%, specificity was 25.0%, PPV was 90.9%, NPV was 66.6% and diagnostic accuracy was 89.9%. Conclusion: We conclude that the combined mammography and ultrasound serve as an important diagnostic tool, both for screening purpose as well as in patients with breast related symptoms for the diagnosis of breast cancer.

Skin cancer is a common and possibly deadly disease that requires immediate and efficient treatment. Conventional surgical methods, although successful, frequently lead to the formation of scars and extended periods of recuperation. In recent years, there have been significant developments in minimally invasive treatments for treating skin cancer. These techniques provide patients with alternative options that result in better cosmetic outcomes and shorter recovery periods. This article is a comprehensive summary of state-of-the-art advancements in minimally invasive procedures, including as laser therapy, cryotherapy, electrochemotherapy, and radiofrequency ablation. We analyze the benefits of these procedures, including minimized scarring, improved cosmetic outcomes, and faster healing periods, while also examining the difficulties and factors involved in their application. We showcase the concrete advantages that patients receive when they undergo minimally invasive therapy for skin cancer, using case studies and success stories as evidence. In addition, we examine potential future paths in research and development, anticipating a favorable outlook for the ongoing use of minimally invasive methods in the treatment of skin cancer. The global prevalence of skin cancer is a substantial health issue, leading to continuous progress in treatment strategies aimed at enhancing patient results. Conventional surgical techniques, however efficient, can lead to conspicuous scarring and extended recuperation periods.

Introduction: Bichatectomy is one of the most common surgeries of the face, but in any of all the hands, it could be a complication, and the most difficult to treat is the Sialocele, so we made an easy way to treat it, and solve it. Surgical Approach: We present a case of a young female, after the bichatectomy in the 5th day the middle face a Tumor, so we decided to create a new stenon duct, with a drainaige in anatomical position, getting a good result at the moment. Discusion: The bichectomy has an important historical antecedent since in the beginning it was a surgery even without importance in the medical field. The removal of Bichat fat currently has more aesthetic than reconstructive purposes, so the increase of the Sialocele is more tan 3% independent the hands of the surgeon. Conclusion: During the complications of bichatectomy, we decide to create an alternative for the surgeons that are in training, and an easy way to solve it.

Intracranial hypotension syndrome may occur secondary to Cerebrospinal Fluid Leak (CSFL). Its etiology can be iatrogenic, traumatic or spontaneous. The most common cause is related to incidental or intentional punctures during anesthetic approaches. It is a rare complication during lumbar spine surgery. The clinical manifestations of this syndrome are characterized by orthostatic headache as the most frequent symptom, accompanied by a wide variety of manifestations, which frequently result in a disability for daily life activities and a delayed recovery. Diagnosis is made through a detailed medical history, the presence of symptoms and signs, and additional imaging studies. Initial treatment is conservative; however, using a hematic patch is recommended for a significant number of patients as the next step, reserving surgical treatment for cases that are not resolved with these measures. This paper presents the clinical case of a 56-year-old female patient diagnosed with CSF fistula following a surgical procedure, which is treated by applying a blood patch with complete remission of symptoms; similarly, a therapeutic algorithm is proposed for the diagnosis of CSFL.

Anorectal Melanoma represents less than 1% of all gastrointestinal tumors. They are infrequent, aggressive and with little therapeutic consensus. The prognosis is usually reserved, with a five-year survival rate of less than 20%. The anorectal canal is the most common place where melanomas of the gastrointestinal mucosa appear. Thus, although it represents 0.05 to 4.6% of anorectal lesions, this constitutes the third most common location of melanoma, after the skin and eyes. Generally, their diagnosis is confusing and late, as they require a high index of suspicion; The symptoms are non-specific but they mostly present as dark, bleeding and painful masses, sometimes being confused with benign anorectal processes such as hemorrhoids. This occurred in two clinical cases that we presented in women aged 78 and 59 years with a purplish-black anorectal mass, the first case confused with hemorrhoidal thrombosis and the other with bleeding internal hemorrhoids; therefore, being treated as such in primary medical care centers and delaying their diagnosis by an average of 3 months (Figure A, B and E). Both cases with high clinical suspicion of a malignant process were later confirmed in a specialized unit, where they underwent biopsies and imaging studies. The patients underwent surgery, with subsequent chemo-immunotherapy. The first with abdomino-perineal resection (Figure C) plus inguinal lymphadenectomy (Figure E) and the other with local excision (Figure F). Both neo or adjuvant treatment and type of surgery remain controversial today.

Background: In the era of modern transportation there is an increased incidence of compound fractures especially of long bones. As the skin barrier is broken, the bacteria from dirt, other contaminants can colonize at the wound site and thus can cause infection. Healing at the fracture site and that of soft tissues can be severely compromised by infection. So, treating the infection first followed by definitive fixation of fracture will nearly take 4-6 weeks. The antibiotic nailing technique can thus achieve both the targets in a short time. Local delivery of drug controls the infection and the fixation achieves stability. This even reduces the side effects due to over use of systemic and oral antibiotics. Osteomyelitis is also very common which can be hematogenous or post traumatic. This can weaken the bone and can cause fractures with trivial trauma. Discharging sinuses may also be accompanying. So even in this scenario long term use of antibiotics systemically may be required causing side effects. Antibiotic nailing can be very useful in this scenario. Methods: This is a prospective observational study. 20 patients above age of 20 years who were admitted or on follow up during the period of 2 years were considered for study. The patients with infected fractures with or without implant in situ and patients with chronic osteomyelitis with discharging sinuses were included. ASAMI Criteria: The final outcome is graded based on ASAMI criteria proposed by Paley et al. This was usually developed for determining the outcome after treatment of nonunion with Ilizarov ring fixator. It was applied in our study with some modification. Results: The average duration for achieving bony union was around 5 months (20 weeks). Minimum duration for bony union was around 4 months (16 weeks). Maximum duration for bony union was around 7 months (28 weeks) Average duration for control of infection in case of chronic osteomyelitis was around 4 months. Minimum duration for control of symptoms was 5 months. Maximum duration for control of symptoms was 7 months. Conclusion: Antibiotic impregnated cement coated intramedullary nailing is a very good and effective treatment for infected nonunion and chronic osteomyelitis long bones with bone defect less than 2 cm. In case of infected nonunion, as the bone ends will be sclerosed, freshening of ends and bone grafting is needed.

Acute abdomen in pregnancy is one of the biggest diagnostic and therapeutic challenges today. Despite advances in medical technology, the preoperative diagnosis of acute abdominal conditions is still inaccurate. Torsion of the adnexa, which refers to complete or partial rotation of the adnexa, resulting in obstruction of venous and lymphatic reflux in the ovary, is a common gynecological emergency. Torn adnexa affect both the ovary and the fallopian tube, and rarely affect only one of them. Adnexal torsion occurs more frequently in the first and early second trimester than in the third trimester. It is difficult to diagnose in advanced pregnancy because of nonspecific symptoms and signs of acute abdomen as well as ultrasound limitations due to uterine enlargement complicate diagnosis. Late diagnosis and delayed surgical treatment result in ovarian loss and fetal endangerment. It is important to thoroughly evaluate the adnexa at the 1st ultrasound examination in pregnancy and to monitor the observed formations.
