Outcomes, Symptomatology, and Mortality of Children Presenting With Bacterial Meningitis at Allied Hospitals of Rawalpindi Medical University, Pakistan: A Cross-Sectional Study.

Introduction Bacterial meningitis (BM) is a neurologic emergency mainly affecting children under the age of two. Clinical symptoms are rarely evident in children, thus making a diagnosis is a challenge. Antibiotic therapy should be started timely to ensure the avoidance of significant morbidity and mortality. This study aims to assess the outcomes, mortality, and symptomatology of children presenting with BM in allied hospitals of Rawalpindi Medical University, Pakistan. Methods It is a cross-sectional study employing a sample size of 201, conducted at the Allied Hospitals of Rawalpindi Medical University, Pakistan from a period of January 2023 to August 2023. Non-probability convenience sampling was used. Children aged between newborns and 14 years of age with a confirmed diagnosis of bacterial meningitis were included in this study. The study population was divided into five different age groups. Three different outcomes were studied including complete recovery, development of complications, and death. Data was entered into and analyzed by Statistical Package for the Social Sciences (SPSS) version 25 (IBM Corp., Armonk, NY, USA). Descriptive statistics were applied to the demographic data. The chi-square analytical test was applied to study the association between the categorical variables. Results One hundred nineteen (59.2%) of the study's population were males. One hundred twenty-six (62.7%) of the patients were born through a spontaneous vaginal delivery (SVD). The majority (54%) of the study population were infants. Twenty-three percent were newborns, 13% were toddlers, 6% were preschool children, and 4% were school-age children. The majority (85%) of the study participants belonged to lower socioeconomic backgrounds. Ninety percent of the cases had symptoms of fever, seizures, and poor feeding. Neck stiffness was significantly associated with death as an outcome (p-value=0.01). The overall mortality amongst the study population was 20%. Forty-nine percent of the study population recovered completely, whereas 31% had complications following the diagnosis. Neonates had a higher mortality rate than infants (45% vs 9% respectively). Conclusion The most common presenting symptoms were fever, vomiting, seizures, and neck stiffness. Poor feeding was also seen in most cases. The rate of complications and death is observed to be relatively higher following the diagnosis of bacterial meningitis as compared to rates in the surrounding and developed countries. Out of all signs and symptoms, the presence of neck stiffness was significantly associated with death as an outcome among children with bacterial meningitis.

Etiological Association Between Psoriasis and Thyroid Diseases.

Psoriasis is a chronic relapsing/remitting autoimmune disease affecting skin and fingernails. It is associated with many other autoimmune diseases such as rheumatoid arthritis, celiac disease, Crohn's disease, and thyroid diseases. Two important autoimmune thyroid diseases - Hashimoto's thyroiditis (hypothyroidism) and Grave's disease (hyperthyroidism) - affect the body's significant organs such as the brain, muscles, digestive function, and the skin. Although some studies have established the connection between psoriasis and thyroid diseases with autoimmunity, our article provides an in-depth analysis of the connection between these two diseases and other common etiological factors associated with them, along with autoimmunity. We reviewed articles from PubMed using regular keywords and Medical Subject Headings (MeSH) keywords and finalized 45 articles to find an association between these two diseases. These articles showed that this association is more prevalent in obese patients and late-onset psoriasis. Most of the articles showed a positive association, but few articles showed no connection between them. However, there is no concrete explanation to prove the association due to limited research; additional studies are necessary. It requires the attention of both clinicians and researchers to develop a universal drug that will work on both diseases, and also thyroid evaluation could be included in psoriatic patient care so that there is a possibility to decrease cost and efforts while treating these diseases.

The Association Between Cholecystectomy and Colorectal Cancer in the Female Gender.

Colorectal carcinoma (CRC) has been of great interest among researchers, and multiple causes have been proposed and accepted; however, cholecystectomy (CMY) as a potential cause for CRC, particularly in the female gender has not been studied in detail, despite multiple evidence suggesting a positive association. This review is directed at investigating the association between CMY and CRC in the female gender and aims at finding a potential cause for this association. CRC involves cancer of the sigmoid and rectum. The composition of the bile acids is altered in patients after CMY, and the resultant secondary bile acids (BA) without a functioning gall bladder are exposed directly to the intestines, which could lead to cancer. An increase in fecal secondary bile acids is also described as high in the CMY population and has been linked to cancer. Right-sided GI cancers were attributed to CMY, although many earlier studies did not find this to be true. It is interesting to note a strong association between CRC and CMY in the female western population.

SARS-CoV-2 (COVID 19) Infection in Hypertensive Patients and in Patients With Cardiac Disease.

COVID 19, caused by the SARS-CoV-2 virus, a newly discovered coronavirus, has caused the global pandemic of early 2020. The first case was described in December 2019 in Wuhan, China, and by March 2020, most countries around the world have put in place some of the strictest restrictions seen in decades in order to slow down the spread of the disease. Patients with pre-existing hypertension and cardiovascular comorbidities were reported to be at an increased risk of serious infections caused by SARS-CoV-2. Considering that those are among the most common chronic medical conditions in the Western world, the potential impact of it is huge. The proposed mechanism behind those associations is the expression of angiotensin converting enzyme II (ACE II) in those patients. Furthermore, the association between ACE inhibitors/AR blockers, which are among the most frequently prescribed medications, and serious cases of COVID 19 has been studied with the same mechanism in mind. The reports on the association between hypertension and COVID 19 morbidity and mortality are less clear, and the International Society of Hypertension even claims that there is none. The reports on the association between heart failure or coronary disease and COVID 19 are more uniform, and all seem to point to a greater risk from serious infections faced by patients with those comorbidities. A significant effort will need to be invested by the scientific community into finding strategies for protecting those patients from contracting the virus in the first place and then, once infected, into developing management plans aimed at preserving cardiac function as much as possible.

Use of Rituximab in Management of Rapidly Progressive Glomerulonephritis.

Rapidly progressive glomerulonephritis (RPGN) is a form of glomerulonephritis characterized by loss of renal function within weeks. Although a variety of underlying causes can trigger RPGN, the ultimate pathologic mechanism is the podocyte and epithelial activation leading to the crescent formation. Rituximab has been increasingly and successfully used for autoimmune conditions in recent years. Treatment of RPGN is based on the underlying condition, but specific clinical guidelines are lacking. In this article, we have tried to establish the role of rituximab in the management of patients with RPGN. All the studies we have used were found in the PubMed database, limited to studies involving adults. Animal studies and studies involving the pediatric population were excluded. The currently available literature does not support switching to rituximab as the first-line agent. It has failed to prove consistently superior to other medications. However, combined with other commonly prescribed treatment regimens, namely corticosteroids, with or without cytotoxic drugs, rituximab has shown efficacy in many studies. Therefore, we have concluded that the most prudent use of rituximab in patients with RPGN would be in those with disease refractory to standard management with corticosteroids and cytotoxic drugs or in those who have intolerable side effects. We believe that clinicians should keep reporting any cases of RPGN treated with rituximab so that a more clear pattern emerges and more exact treatment guidelines can be made.

Clinical Applications and Benefits of Using Closed-incision Negative Pressure Therapy with Novel Dressing: A Review Article.

Surgical site occurrences (SSOs) are common in patients undergoing operative procedures, especially in the form of surgical site infections (SSIs). Multiple studies show that obesity, tobacco use, prolonged surgical time, and diabetes mellitus are the major risk factors for SSIs. SSIs increase healthcare costs and often result in morbidity. Many surgeons are currently using closed-incision negative pressure therapy (ciNPT) to counter SSIs. This method makes it easier for them to manage closed and surgical incisions. This technique has already been applied in the plastic surgery field. This study discusses how the use of ciNPT is helping surgeons to reduce complications related to SSOs. The technique has been reported to minimize the rate of reoperations, readmissions, and other wound-related complications. Using ciNPT with novel dressing has proved to be a significantly effective clinical intervention method in managing clean and closed wounds. The novel dressing protects the incision from external contamination and minimizes lateral tension.

Associations and Outcomes Between Chronic Traumatic Encephalopathy and Vasculitis in Adult Patients.

Chronic traumatic encephalopathy (CTE) results from brain injuries and traumas due to accelerated impacts on the head. In severe cases, the diseases cause brain damage, given the head trauma. On the other hand, vasculitis occurs through antibodies that mistake protein vessels as foreign, hence fighting them and resulting in their damage. Examination is usually conducted through blood tests, with antibodies being identified in the antineutrophil cytoplasm. It is unfortunate that its devastating effects also affect the brain of a human, hence leading to dis-functioning. When vasculitis is left untreated, it results in multiple adverse effects on the human body and health both in the short term and in the long term. This study aims to bring to the awareness of neurosurgeons the associations between CTE and vasculitis. This study has proved that there is a close correlation between the progression of CTE and vasculitis. The inflammatory of the blood vessels, as witnessed in vasculitis, increases the risk factors for CTE. The scaling of the vessels and manifestation of different vasculitis conditions in active central nervous system cells results in the worsening of neurodegeneration of the CTE disease.

Radiation Therapy as a Modality to Create Abscopal Effects: Current and Future Practices.

In our empathetic understanding of abscopal effect (AbE), research has shown that the immune system is stimulated by radiation, which results in the formation of an AbE. The AbE is referred to as a response from the irradiated volume. Despite the existence of key gaps in our understanding, there is an urgent need to explore what the underlying effect is. The aim of this article is to argue neurosurgeons and the healthcare practitioner's knowledge of the AbE. Our goal is to identify more gaps in our understanding of the AbE and seal other gaps as well. This study will review medical journals and bring together the most updated information related to AbEs.

Uncommon Presentations of Multiple Myeloma.

Multiple myeloma is a rare malignancy that exhibits a wide range of possible clinical presentations. In recent years, with the advent of stem cell transplantation, the prognosis of patients with multiple myeloma has been increasing. We searched the literature for reports of atypical myeloma presentations to aid clinicians in formulating differential diagnoses and to increase the number of cases diagnosed early. There have been a number of reports of early ocular symptoms, including, but not limited to, proptosis, optic neuropathy, vision loss, retinal hemorrhage, and detachment. Neurological presentations included cranial nerve palsies, vertigo related to cerebellar involvement, and diabetes insipidus related to pituitary involvement. Among gastrointestinal manifestations, there are a number of reports of multiple myeloma presenting as acute and chronic pancreatitis. Mesenteric ischemia due to amyloidosis, acute abdomen, and hepatosplenomegaly were also among reported presentations. When it comes to renal involvement, while acute renal failure and proteinuria are typical, there are reports of patients presenting with both nephritic and nephrotic forms of glomerular disease, as well as end-stage renal disease requiring dialysis. We believe that it is essential for clinicians to keep reporting atypical multiple myeloma presentations and consider it as a possible diagnosis in a patient with serious, atypical symptoms.

Thyrotoxic Periodic Paralysis With Features of Andersen-Tawil Syndrome: A Case Report and Literature Review.

Thyrotoxic periodic paralysis (TPP) is a rare manifestation of hyperthyroidism. The pathophysiology of hyperthyroidism causing periodic paralysis involves the Na+/K+ ATPase and potassium channels. We present a case of a 30-year-old male who presented to the ED with acute onset of upper and lower limb weakness. The patient was found to have bilateral weakness in the upper and lower limbs, orbital hypertelorism, and mandibular hypoplasia. He was also found to have hypokalemia, low thyroid-stimulating hormone (TSH), elevated thyroid peroxidase antibody, and elevated thyroid-stimulating immunoglobulins. The patient's EKG was remarkable for a prolonged QTc interval. The patient regained his muscle strength after potassium replacement in less than 24 hours. He was started on methimazole and potassium supplements. Our case is unique because it shows the possibility of the presence of Andersen-Tawil syndrome (ATS) (long QT syndrome 7), diagnosed by the presence of periodic paralysis, long QT, and dysmorphic facial features with TPP. In conclusion, thyrotoxicosis can trigger ATS; also the two syndromes can co-exist owing to the similarity in their pathophysiology.

Coronavirus Disease 2019 (COVID-19) in Cancer Patients.

The Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become the most talked-about clinical entity in early 2020. As an infection that spreads easily and has a significant mortality rate, it has caused global panic rarely seen before. Many of the measures taken by governments worldwide will have long-lasting impacts on the wellbeing of the population at large. It has been widely reported that the most vulnerable patients have been most negatively affected by SARS-CoV-2 (COVID-19). In this study, we have tried to search the currently available data on the outcomes of infected cancer patients. Most of the data points to the very challenging nature of treating such patients. Their overall outcomes seem to be worse than in the general population, and it may be difficult to differentiate which potential complications are a result of the primary oncologic disease versus the infection. Management presents its own set of challenges, including but not limited to, deciding whether postponing cancer treatment until the infection resolves is going to benefit the patient and how to organize all aspects of patient care when social contact is as limited as it is for patients newly diagnosed with COVID-19. We believe that as more data becomes available, it is going to be necessary to publish detailed guidelines on how to approach this unique clinical challenge.

The Effect of Zinc on Post-neurosurgical Wound Healing: A Review.

The aim of this article is to explore neurosurgeons' knowledge and understanding of the physiology of zinc and provide current information about the role zinc plays in post-neurological wound healing. We review several medical journals and bring together the most updated information related to lesion-healing after surgery.

The Role of Circadian Misalignment due to Insomnia, Lack of Sleep, and Shift Work in Increasing the Risk of Cardiac Diseases: A Systematic Review.

Around 121.5 million people suffer from cardiovascular diseases globally. The risk of cardiovascular diseases increases with advancing age in both genders. Circadian rhythm is responsible for a streamlined functioning of various body functions. Certain functions and hormones have their peak levels according to the biological day or night of circadian rhythm. Shift work and sleep disorders like obstructive sleep apnea can cause circadian misalignment that affects different metabolic, immunological, and cardiovascular functions, which ultimately increases the risk of cardiovascular diseases. We systematically searched the online database PubMed to find papers on randomized controlled trials (RCTs) from the past five years, evaluating the role of shift work and different sleep disorders in causing circadian misalignment and its effect on the risk of cardiovascular diseases. Fifty papers were shortlisted, and after the application of various inclusion and exclusion criteria, 18 papers were chosen; and then after a thorough analysis of the text, eight papers were selected for the review. All papers were evaluated for quality. Two papers focused on the effect of shift work on cardiovascular diseases, whereas five papers evaluated the role of sleep disorders on circadian rhythm and the risk of cardiovascular diseases. Shift work and sleep-related disorders were found to cause circadian misalignment, and it was found to be associated with an increase in the risk of cardiovascular diseases. Managing these disorders can help reduce the risk of cardiovascular diseases.

Distal Radial Artery Access: The Future of Cardiovascular Intervention.

Access sites for coronary intervention have been changing over the last several decades, from the femoral artery to the radial artery and then to the distal radial artery. Distal radial access, which was first used in 2017 and is still not recommended by the guidelines, shows a higher success rate and less complications than other sites; therefore, it might be the future for cardiovascular intervention. In this study, we reviewed almost all of the articles that are related to the distal radial access, from 2017 to present, and summarized the technique, success rate, advantages, disadvantages, and noncardiac use of this access site.

The Role of Propionibacterium acnes in the Pathogenesis of Sarcoidosis and Ulcerative Colitis: How This Connection May Inspire Novel Management of These Conditions.

A lesser-acknowledged role of Propionibacterium acnes is its effect on the development of sarcoidosis. This literature review not only further explores this association but also that of Propionibacterium acnes and other inflammatory conditions, such as ulcerative colitis and pyoderma gangrenosum, acne, ulcerative colitis syndrome (PAC syndrome). This article reviews the effect that isotretinoin, a commonly used treatment of acne, has on the pathogenesis of ulcerative colitis, and the immune dysregulation and genetic susceptibility of individuals prone to developing acne, sarcoidosis, and ulcerative colitis. Literature for this article review was obtained from PubMed by utilizing both regular keywords and medical subject heading (MeSH) subheadings for data gathering. Regular keywords were: Propionibacterium acnes, sarcoidosis, ulcerative colitis, and isotretinoin. MeSH subheadings used were: Propionibacterium acnes/immunology, Propionibacterium acnes/pathogenicity, Propionibacterium acnes/genetics, sarcoidosis/immunology, and sarcoidosis/genetics. Following the application of inclusion and exclusion criteria, a total of 5172 publications were obtained. A total of 5086 publications were removed due to a lack of relevancy to outcomes of interest. The remaining 86 publications from all the regular and MeSH keywords were selected due to relevancy to outcomes of interest. Following this, a refined manual search was done, with the removal of duplicates, and 33 publications from PubMed were selected for review. Following a review of these records, Propionibacterium acnes was repeatedly concluded to be a causative agent of sarcoidosis. Variable results for the association between Propionibacterium acnes and ulcerative colitis were found. Most studies showed no significant association between the use of isotretinoin and the development of ulcerative colitis. A strong overlapping role of genetic susceptibility and immune dysregulation in the pathogeneses of sarcoidosis, ulcerative colitis, and Propionibacterium acnes was found.

Managements for Obstructive Sleep Apnea in Adults: Review.

Obstructive sleep apnea (OSA) is characterized by recurrent obstruction of the pharyngeal airway during sleep, with resultant hypoxia and sleep fragmentation. It is more common in middle-aged obese men and prevalence is higher in most obese people. However, prevalence is high in African-Americans. OSA is associated with major comorbidities including excessive daytime sleepiness and increased risk of cardiovascular diseases. First and foremost, OSA management starts from educating patients about short-term consequences like motor vehicle accidents, behavioral modifications, long term consequences like cardiopulmonary disease, and resistant high blood pressure. Various types of management options are available for OSA such as weight loss, CPAP, oral appliances, and surgery. The review aims to explain the pathophysiology and cause of the obstruction of the airway in order to choose proper management carefully to decrease the symptoms and cure the disease.

Otosclerosis and Measles: Do Measles Have a Role in Otosclerosis? A Review Article.

Otosclerosis is a common cause of conductive hearing loss which is an autoimmune inflammatory disorder related to abnormal bone remodeling of the human otic capsule that has complex etiopathogenesis attributed to genetics, autoimmunity, viral infection, inflammation, hormonal factor, environmental factor, and disturbed bone metabolism. It has a prevalence of 0.3%-0.4% in Caucasians, which makes up 5-9% of all hearing loss and 18-22% of all conductive hearing loss. This review article aims to study the postulated role of sustained measles virus infection in the etiopathogenesis of otosclerosis, among others. A PubMed search of the related topic identified 97,990 articles. After we applied the inclusion and exclusion criteria, it was determined that 52 articles were relevant, which included 38 observational studies, 13 review articles, and a systematic review. Among them, 33 observational studies, 13 review articles and a systematic review spotted a positive association between persistent measles virus infection and otosclerosis. On the contrary, five observational studies reported no evidence of the association. The majority of the current literature supported the presence of the measles virus component in the otosclerotic stapes samples and its role in the etiopathogenesis of otosclerosis. Measles virus infection may have the amplitude to initiate a pathological process, which in the presence of other factors like autoimmunity and genes plays a significant role in causing otosclerosis. However, other studies have failed to show the presence of the measles virus component in otosclerotic stapes. So, more studies are needed to probe the role of persistent measles virus infection in the etiopathogenesis of otosclerosis.

Parkinson's Disease and Its Dermatological Associations: Is Your Skin Whispering You a Diagnosis?

Parkinson's disease (PD) is a neurodegenerative disease characterized clinically by the triad of resting tremor, rigidity, and bradykinesia. Although PD is primarily known for motor disturbance, 98.6% of patients experience one or more non-motor symptoms at all stages of the disease. Dermatological disorders are discussed as common non-motor associations of PD since the 20th century. Many studies have shown that patients of PD are predisposed to skin disorders. This article is a traditional review done to analyze the association between PD and its dermatological manifestations. We did a literature search using six keywords in the PubMed database and took the relevant articles published in the last 10 years. We reviewed more than 100 articles, which also included animal studies. On meticulous review, we observed an increased incidence of certain skin disorders like seborrheic dermatitis, bullous pemphigoid, rosacea, and melanoma in patients of PD. These disorders share either common risk factors or underlying mechanisms revolving around genetics, immunology, inflammation, and pathophysiology of PD, but the exact causation yet seems obscured. We believe that this opens a horizon for more research in the link between the skin and nervous system. We also emphasize that the dermatologists, neurologists and general physicians should address the cutaneous disorders in PD timely, educate their patients, help them lessen the psychosocial distress, and improve their quality of life.

Neuroprotective and Neurodegenerative Aspects of Coffee and Its Active Ingredients in View of Scientific Literature.

Coffee and its components have several neuroprotective properties that lower the risk of cognitive decline and other neurodegenerative diseases. This study reviews the mechanisms by which coffee and its respective compounds affect the brain and its pathologies. Many epidemiological studies in this literature review have shown coffee to reduce the risk of developing dementia, stroke, and Alzheimer's disease. It may also have a positive impact on the disease course of amyotrophic lateral sclerosis, Parkinson's disease, and depression. The optimal benefits achieved from coffee in these pathologies rely on higher daily doses. Most of its effects are attributed to caffeine by the antagonism of adenosine receptors in the central nervous system; however, other coffee constituents like chlorogenic acids have also shown much promise in therapeutic value. Existing research considers coffee to have great potential, but additional studies are still needed to clarify the mechanisms and actual causal relationships in certain neuropathologies.

Cardiomyopathy in Sickle Cell Disease.

Sickle cell disease (SCD) is an inherited disorder that occurs due to point mutation in the beta-globin chain resulting in the production of hemoglobin S that tends to become rigid and sickle-shaped under low oxygen concentration. These sickle-shaped red blood cells (RBCs) obstruct the blood vessels leading to reduced blood flow to the organs, causing ischemia and tissue fibrosis. These sickle RBCs being abnormal in shape are frequently sequestered by the spleen, creating a state of chronic anemia in the body. This chronic anemia leads to a high cardiac output state causing cardiac remodeling. To tackle chronic anemia, patients are frequently treated with blood transfusions that makes them more prone to the risk of iron overload (from newly transfused RBCs and iron release from the RBCs that just got sequestered as well as from volume overload) and volume overload causing left ventricular (LV) dilation. The above-mentioned mechanism of cardiac hypertrophy, along with LV dilation together, makes SCD-related cardiomyopathy unique cardiomyopathy with features of restrictive cardiomyopathy with LV dilation. It is interesting to note here that even though there is a presence of LV dilatation, Systolic dysfunction is very uncommon in SCD-related cardiomyopathy.
