Famciclovir is a prodrug antiviral agent. It is modified by esterase and an oxidase, which converts it into its active antiviral agent penciclovir. Famciclovir is the diacetyl 6-deoxy analog of penciclovir. Famciclovir is used for the treatment of acute herpes zoster (shingles) caused by the varicella-zoster virus (VZV) and herpes labialis (cold sores) caused by herpes simplex virus (HSV) in immunocompetent patients. Also, famciclovir is used for the treatment of an initial and recurrent episode of genital herpes simplex virus in immunocompetent and HIV infected patients. Also, it is an agent for the treatment of genital HSV chronic suppressive therapy. There is also evidence that famciclovir may lower hepatitis B viral DNA levels in patients when used as a long-term treatment. This data suggests that famciclovir may be useful in treating chronic hepatitis B viral infections. The incidence and duration of postherpetic neuralgia are not affected in the patients treated with famciclovir for acute herpes zoster (shingles).Vasodilation is the widening of blood vessels as a result of the relaxation of the blood vessel muscular walls. Vasodilation is a mechanism to enhance blood flow to areas of the body that are lacking oxygen and/or nutrients. The vasodilation causes a decrease in systemic vascular resistance (SVR) and an increase in blood flow, resulting in a reduction of blood pressure.The concept of nerve stimulation/peripheral nerve stimulation (PNS) is not new and has been in practice since the early 19 century. However, clinical studies were done much later in this field. In 1976, Campbell et al. published the reports of the first set of clinical studies done in the field of pain management using PNS. Since then, PNS has been actively explored as a treatment of modality for managing chronic pain conditions. Chronic pain conditions, including low back pain, neck pain, and neuropathic pain states like chronic regional pain syndrome, causalgia, and diabetic neuropathy, afflict a large group of population. They pose a substantial economic burden on society. These pain conditions are the leading cause of disability in the world. Currently, there is an active opioid crisis in the United States, with over 15,000 deaths involving prescription opioids reported in 2015. Also, managing these chronic pain conditions with conventional medical management can lead to multiple drug-drug interactions resulting in intolerable side effects. PNS offers a relatively safe and effective treatment modality in the treatment of such chronic pain conditions.Waardenburg, in 1918 first described the pigmented iris hamartomas. Karl Lisch, an Austrian ophthalmologist, in 1937 reported the association of these iris hamartomas with neurofibromatosis type 1 (NF1). The term Lisch nodule was used first by Riccardi in 1981 in a formal publication. Lisch nodules (LNs) are the melanocytic hamartomas found in 90% to 100% of adults with NF1 and are the most consistent features of NF1. A German pathologist named Friedrich Daniel Von Recklinghausen identified NF1 as a genetic disease. NF1 considered a neurocristopathy, is an autosomal dominant disorder with a high mutation rate characterized by pathological hamartomas proliferation of neural crest-derived tissues. selleck compound LNs, as such, do not cause any visual disturbances, but the associated life-threatening as well as vision-threatening conditions, merit discussion.Total hip arthroplasty offers a reproducible alternative to individuals who have painful arthritis of the hip. The advancements in medicine have improved patient outcomes in arthroplasty and decreased hospital length of stay. Cooperation with the anesthesia department has revolutionized perioperative and postoperative pain management to limit narcotic use. Interprofessional preoperative management with the primary care team seeks to optimize a patient before surgery or delay patients unfit for elective arthroplasty. Improved patient selection and widespread availability of implants have allowed primary total hip arthroplasty to be performed in patients of a wide age range and often completed as an outpatient surgery. The desire for primary total hip arthroplasty is predicted to rise from 329,000 to 572,000 operations in 2030, a 174% rise from 2005. A focus on individual health and preventative medicine combined with medical advancements, patients are surpassing previously established life expectancies. The increased utilization in total hip arthroplasty has led to a concurrent increase in periprosthetic fractures. Operative fixation of a periprosthetic fracture is taxing surgery that is best suited for surgeons with a significant volume of related procedures and understanding of the complexities of the operative planning.Genitourinary tuberculosis (GUTB) is defined as the infection of the urinary tract or genitalia most commonly caused by Mycobacterium tuberculosis. GUTB term was coined by Hans Wildbolz in 1937. GUTB comprises 20% of all extrapulmonary tuberculosis. Following pulmonary tuberculosis, 2% to 20% of individuals can develop genitourinary tuberculosis after 5 to 25 years. An estimated 10 million people got infected with tuberculosis worldwide, out of which 1.5 million people died in 2018, according to the World Health Organization. About one-quarter of the world's population has latent TB. Tuberculosis is curable and preventable. Tuberculosis spreads from person to person through the air droplets. Classification Renal and Urologic Tuberculosis Most commonly involves the urinary collecting system (renal pelvis, calyces, ureter, and bladder) and less commonly involves renal parenchyma. Genital Tuberculosis Involves epididymis, testis, urethra, and prostate in the male and Fallopian tube, endometrium, and ovaries in the female. Renal and prostatic TB is due to hematogenous spread of mycobacterium from a chronic latent pulmonary infection. Other genitourinary organs are affected by the local spread of infection.Rectal foreign bodies (RFB) are not new to medical literature. One of the earliest examples of rectal foreign bodies (RFBs) ever reported dates back to the 16 century. RFBs cases are no longer a rare presentation in emergency departments, and their incidence is rising, specifically in urban populations. The average age of presentation is 44 years, and there are more commonly seen in men. Although there are various objects inserted in the rectum, the most common among them are glass bottles (42.2%). There are many reasons for rectal foreign body insertion including, sexual gratification, concealment, as may be the case in body packers, sexual assault, and, rarely, accidental causes, but the most common purpose is autoeroticism due to the increasing use of a different object for anal sex. The time of presentation varies; some people consult emergency services immediately because of their inability to remove the object. At the same time, other patients might take up to two weeks before the presentation due to embarrassment.
