We identified a regional dichotomy in murine lymphatic contractile function with regard to vessel location within either the periphery or visceral cavity. All vessels isolated from peripheral regions; cervical, popliteal, inguinal, axillary, and inter-nodal inguinal axillary (Ing-Ax) developed robust contractions with maximal ejection fractions (EFs) of 50-80% in our ex vivo isobaric myograph experiments. Conversely, vessels isolated from the visceral cavity (mesenteric, TD, and iliac) demonstrated maximal EFs below 15%...

Since 2003, there has been a resurgence of lymphogranuloma venereum (LGV), a variant of Chlamydia trachomatis (CT), among men who have sex with men (MSM) in several urban areas of Europe and North America. LGV infection occurs most often at anal sites causing proctitis. Urethral and oropharyngeal infections are rare. In Quebec, LGV incidence has been increasing exponentially in recent years and the current guidelines support systematic LGV genotype testing among anorectal CT-positive samples only. This case report describes a patient with a urethral LGV infection, remarkable due to its prolonged asymptomatic development prior to the manifestation of an inguinal bubo...

Twenty-one sides of 11 adult Japanese cadavers were investigated, and 2 of 21 sides exhibited absence of the pyramidalis. We observed that all of the nerves to the pyramidalis included the sensory nerve branch, which distributed to the aponeurotic tissue in the upper area of the pubic ramus. To investigate the clinical relevance and developmental process of the pyramidalis, detailed innervation patterns of the pyramidalis and the lumber plexus were examined and compared with the case of absent pyramidalis. The nerves to the pyramidalis could be classified into five types by the derivative nerves and two subtypes by their courses associated with the funiculus spermaticus...

Intravascular leiomyomatosis (IVL) is a benign smooth muscle tumor that evolves from the pelvic veins and can spread to the central veins and heart. Cardiac involvement is the most commonly reported presentation. Initial diagnosis is difficult, and IVL is commonly misdiagnosed as thrombus or atrial myxoma. Appropriate imaging and a high clinical suspicion are required for accurate diagnosis. We report a rare case of IVL in the external iliac vein that recurred 4 years after hysterectomy. Only four cases have been reported in the literature to involve the external iliac vein as it has no direct connection to pelvic venous drainage...

A 73-year-old woman was admitted for left groin bleeding through an open wound near a fungating left inguinal mass from advanced anal carcinoma. The interventional radiology service placed left iliac vein and common femoral vein stents as there was concern for communication and involvement of the left common femoral vein with the open wound, contributing to groin hemorrhage. After the procedure, the patient developed limb ischemia related to mass effect of the stent on the left common femoral vein stent artery...

Hernioscopy is essentially hernia sac laparoscopy. Hernia repair has evolved over the years with better outcomes; however, strangulated inguinal hernias are acute surgical emergencies which require emergent operative intervention. During anesthesia induction and/or after incision, hernia self-reduction is possible, with or without compromised bowel, back into the abdominal cavity. It is pivotal to examine the bowel to decide on further operative course. A simple alternative to unnecessary laparotomy or standard laparoscopy is hernioscopy, which is quite uncommon...

A 30-year-old Javanese-Indonesian man was admitted with complaints of 3 months persistent fever, weight loss, and fatigue. He had never known his past history of unprotected HIV until the admission. His only risk factor is unsafe sex. The patient seemed well nourished. Physical examination revealed blood pressure 100/60 mmHg, pulse 100 beats per minute, respiratory rate 20 times per minute, and temperature 38.8°C. Multiple cervical and inguinal lymphadenopathies were also found. Electrocardiogram showed anterolateral ischemic finding, whereas chest X-ray were normal...

Integrin α4β7 mediates the trafficking of leukocytes, including CD4+ T cells, to lymphoid tissues in the gut. Virus mediated damage to the gut is implicated in HIV and SIV mediated chronic immune activation and leads to irreversible damage to the immune system. We employed an immuno-PET/CT imaging technique to evaluate the impact of an anti-integrin α4β7 mAb alone or in combination with ART, on the distribution of both SIV infected cells and CD4+ cells in rhesus macaques infected with SIV. We determined that α4β7 mAb reduced viral antigen in an array of tissues of the lung, spleen, axillary, and inguinal lymph nodes...

Plexiform vasculopathy refers to an endothelial proliferative disorder affecting cervical or inguinal lymph nodes of cats. The cause of this disorder and the origin of the proliferating endothelial cells are still unknown. In 4 cats with a history of a slowly growing, well-demarcated, nonpainful mass adjacent to the thyroid gland, an enlarged dark brown to red lymph node was removed. Histologically, the lymph nodes showed severe loss of lymphoid tissue with accumulations of erythrocytes. In addition, networks of capillary structures with well-differentiated endothelial cells on a collagen-rich stroma were observed, consistent with benign plexiform vasculopathy...

INTRODUCTION: Thrombosis is defined as the formation of a clot in a blood vessel that obstructs the flow of blood to the peripheral tissues. The incidence of thromboembolic disease ranges from 0.7 to 1.2% within urology. CASE REPORT: A 40-year-old warehouse worker male presented to the emergency department with worsening of a month's lasting scrotal pain. Physical examination showed the presence of an enlarged and painful left testicle with no other findings. Right testicle, penis and abdominal examination showed no abnormalities whatsoever...

BACKGROUND: Predicting recovery of consciousness is one of the most essential functions of anesthesia depth monitors in anesthesia practice. Perfusion index and bispectral index are 2 indicators of the anesthesia depth monitoring with different working principles. The progression of the anesthesia emergence stages reflected by those monitors has not been well understood, especially in pediatric patients. The goals of this study were to compare the prediction probabilities of perfusion index and bispectral index in predicting awakening and in differentiating the different levels of arousal during emergence after sevoflurane anesthesia in children undergoing open inguinal hernia repairs...

Neuro-axial anesthesia has been the preferred technique for inguinal hernia repair when attempting to avoid general anesthesia in neonates and preterm infants. We present a case where an erector spinae plane block was used successfully for this surgery. Hemodynamic stability, minimal anesthetic requirements, and excellent pain control were documented. This block promises to be a valuable and safe alternative for inguinal hernia repair, accompanying the path of neuroprotective anesthesia.

BACKGROUND: The aim of this study is to investigate the cumulative incidence and risk factors of postoperative inguinal hernia (PIH) in patients undergoing radical prostatectomy, i.e., laparoscopic prostatectomy (LRP) and robot-assisted laparoscopic prostatectomy (RARP). METHODS: This study included 1124 patients who had undergone radical prostatectomy or transurethral resection of bladder tumor from 2011-2016. We compared the cumulative incidence of PIH in the radical prostatectomy groups (460; LRP 341, RARP 119) and the control group (664; transurethral resection of bladder tumor), and we then analyzed the risk factors (age, operative methods, previous abdominal operative history, thickness and width of external oblique muscle and rectus muscle, thickness of abdominal subcutaneous fat layer at Hesselbach's triangle level, body mass index, prostate-specific antigen, operative time, specimen weight, Gleason score, and pathology T-stage) of PIH in the radical prostatectomy groups...

David S Edelman
Laparoscopic inguinal hernia repair has certain advantages over open repair including less pain and earlier return to normal activity. Concurrent robotic inguinal hernia repair at the time of prostatectomy has been shown to have a lower recurrence rate than open repair. Robotic surgery adds high definition visualization and articulating instruments which enhances dexterity that makes laparoscopic hernia repair more refined. A series of robotic, laparoscopic, inguinal hernia repairs by a single surgeon with an extensive laparoscopic hernia experience at a single institution was undertaken to determine the role of robotic laparoscopic inguinal hernia repair in minimally invasive surgery...

We present a randomized clinical trial to compare postoperative pain, complications, feeling of a foreign body, and recurrence between heavyweight and lightweight meshes in patients with bilateral groin hernia. Sixty-seven patients with bilateral hernia were included in our study. In each patient, the side of the lightweight mesh was decided by random numbers table. Pain score was measured by visual analogue scale, on 1st, 3rd, 5th, and 7th postoperative day, and one year after the surgery. There were no statistically significative differences between both meshes in postoperative complications...

General Douglas MacArthur was a towering public figure on an international stage for the first half of the 20th century. He was healthy throughout his life but developed a series of medical problems when he entered his 80s. This article reviews the General's medical care during two separate life-threatening medical crises that required surgical intervention. The first episode occurred in 1960 when MacArthur presented with renal failure due to an obstructed prostate. Four years later after his 84th birthday, MacArthur developed bile duct obstruction from common duct stones...
