Bleeding in newborns and young girls fascinated writers for more than a millennium. Initially, there was confusion between neonatal bleeding, early menstruation due to precocious puberty, and hemorrhage due to disease. During the 19th century descriptions appeared of what is referred to today as ‘neonatal menstruation’ or ‘neonatal uterine bleeding’. By the turn of the century, Halban linked bleeding to active substances present during pregnancy and hypothesized that, while the maternal uterus reacts with decidua formation, the “weaker” fetal uterus reacts only with menstrual-like changes. Despite this clear description, several alternative theories endured for decades. Bleeding was believed to be due to a ‘catarrhal’ or neoplastic state of the genital tract, pulmonary circulatory disorder, congenital heart malformations, closure of the umbilical cord or affections of the intestine. During the 1950s, progesterone response and resistance were proposed to explain the pathogenesis of bleeding and its low incidence. The fetal endometrium is resistant to the high circulating progesterone. A decidual response is infrequent and results in menstrual shedding upon progesterone withdrawal after birth. Further research linked fetal stress consequent to pregnancy complications and post-maturity to increased incidence and preterm birth to reduced incidence of neonatal uterine bleeding.

AbstractThe cause of idiopathic sudden sensorineural hearing loss (idiopathic SSNHL)—diagnosed after excluding other causes of hearing loss, such as SSNHL associated with vestibular schwannoma (VS)—is unknown. The presumed pathogenesis of idiopathic SSNHL includes circulatory disorders (e.g., cochlear infarction). We tested the hypothesis that patients with SSNHL who are at high stroke risk will have a lower rate of VS compared to those with low stroke risk. The rationale is that the primary cause of SSNHL in patients with high stroke risk might be a circulatory disturbance. We conducted a retrospective study in six hospitals. Our sampling of SSNHL patients included those diagnosed with idiopathic SSNHL and VS-associated SSNHL. SSNHL patients who had a head MRI were stratified by severity of hearing loss and evaluated for differences in the detection rate of VS between the high-scoring CHADS2 (CHADS2-H-), an index of stroke risk, and low-scoring CHADS2 (CHADS2-L-) groups. We identified 916 patients who met the inclusion criteria. For severe hearing loss, the CHADS2-H group had a significantly lower rate of VS than the CHADS2-L group (OR 0 [95% CI 0.00–0.612]; P = 0.007). These results indirectly support the hypothesis that a primary cause of severe idiopathic SSNHL in those at high risk of stroke might be a circulatory disorder.

An anal fissure is one of the most common diseases of the anal canal with the incident rate of 20–23 cases per 1000 citizens. Most of acute anal fissures are healed spontaneously but a few of them can become chronic process. Chronic anal fissures are characterized by any two of the criteria: pain after defecation lasts longer than 3 months, sentinel pile is present, fibers of internal sphincter at the base of the anoderm.The spasm of the internal sphincter is a guiding pathogenetic mechanism in the development of chronic anal fissures. It leads to circulatory disorder in the anoderm and non-healing wounds. Therefore, the treatment of anal fissures primarily must be focus on eliminating of internal sphincter spasms and then excising of fissures.Recently, botulinum toxin type A injection in treatment of chronic anal fissures has become popular as a noninvasive method of eliminating internal sphincter spasms.Botulinum toxin as a medical agent has been studied since the late 1960s. Botulinum toxin type A has been used to treat of various pathologies including coloproctology diseases for more than 40 years.The botulinum toxin injections make the internal sphincter relax, and as a result create optimal conditions for healing chronic anal fissures.Using of botulinum toxin type A does not cause dangerous complication. Fecal incontinence after using botulinum toxin is transitory.The review describes the use of botulinum toxin type A injections to treat chronic anal fissures.

This report describes the intraoperative course of endoscopic thyroidectomy by oral vestibular approach in a female patient. This operation is new, and its perioperative management is not yet mature. In this case, the surgery resulted in trachea injury that could not be detected easily. As a result, the patient suddenly developed acute dyspnea and circulatory disorder. This procedure requires caution in surgical execution and anesthesia management.

Previous studies have investigated whether migraine is a circulatory disorder, as migraineurs are at heightened risk of cerebrovascular disease. However, in most cases, systemic vascular function was evaluated, which may not reflect abnormalities in the cerebral circulation. Therefore, we aimed to determine whether cerebrovascular function differs between migraineurs and controls. A systematic literature search was conducted across three electronic databases to search for studies that compared cerebrovascular function in migraineurs to controls. Where applicable, meta-analyses were used to determine standardised mean differences (SMD) between migraineurs and controls. Seventy articles were identified, 40 of which contained quantitative data. Meta-analyses showed pulsatility index (PI) was higher (SMD = 0.23; 95%CI = 0.05 to 0.42, P = 0.01) and cerebrovascular responsiveness (CVR) to hypercapnia was lower (SMD=−0.34; 95%CI=−0.67 to −0.01, P = 0.04) in the posterior circulation of migraineurs, particularly those without aura. The meta-analyses also indicated that migraineurs have higher resting mean blood flow velocity in both anterior (SMD = 0.14; 95%CI = 0.05 to 0.23, P = 0.003) and posterior circulations (SMD = 0.20; 95%CI = 0.05 to 0.34, P = 0.007). Compared to healthy controls, migraineurs have altered cerebrovascular function, evidenced by elevated PI (representing arterial stiffness) and impaired CVR to hypercapnia (representing cerebral vasodilator function). Future studies should investigate whether improvement of cerebrovascular function is able to alleviate migraine.

Abstract Escharotomy is the relaxation of an eschar through longitudinal or horizontal incisions in order to protect regional perfusion. In peripheral areas, such as limbs, trunk, and neck, eschar pressure poses significant issues; it causes circulatory disorder in limbs and potential limb loss, inadequate thoracic expansion in the thorax, and perfusion and oxygenation problems in the neck. To prevent complications, a basic rule of burn surgery is to perform escharotomy incisions quickly and without hesitation. However, the face is not an area in which eschar formation is commonly seen due to its robust vascular supply and patients’ protection reflex. Although descriptive drawings and guides for facial escharotomy have yet to be published, relaxation of axial arteries in terms of compression from eschar formation may be needed. Here, we present a case of escharotomy based on facial subunit principles.

Pregnancy also known as gravidity, is the duration which one or more offspring develops inside a woman. A multiple pregnancy involves more than one offspring, such as with twins. Pregnancy can occur by sexual intercourse or assisted reproductive technology. In the pregnancy which lasts about 40 weeks, is grouped into three trimesters. Maternal physiologic adaptations are attributed to the hormones of pregnancy and to mechanical pressures arising from the enlarging uterus and other tissues. These adaptations protect the woman’s normal physiologic functioning, meet the metabolic demands pregnancy imposes on her body, and provide a nurturing environment for foetal development and growth. Although pregnancy is a normal phenomenon, problems can occur. The hormonal and physical changes of pregnancy result in enormous changes in a woman’s body. Enormous amount of estrogen is produced which leads to the discomforts during pregnancy. Common musculoskeletal discomforts are back pain, sacroiliac joint dysfunction, leg cramps, nerve compression syndromes like carpel tunnel syndrome, brachial plexus pain, meralgia paraesthetica, posterior tibial nerve compression, circulatory disorder such as varicose vein in the legs, vulval varicose vein, haemorrhoids, cramp, thrombosis and thrombo embolism, thoracic outlet syndrome, thoracic spine pain, postural back ache, osteoporosis of pregnancy, fatigue, insomnia and nightmares.
