Clinical Significance of Nocturnal Hypertension and Nighttime Blood Pressure Dipping in Hypertension.

PURPOSE OF REVIEW: This narrative review article aims to discuss more recent evidence, current challenges, and future perspectives regarding the clinical importance of nocturnal hypertension and nighttime blood pressure dipping, with particular reference to diagnosis, prognostic value, and therapeutic approach. RECENT FINDINGS: The importance of nighttime blood pressure and nighttime blood pressure dipping has been demonstrated in decades. Increased nighttime blood pressure has been acknowledged as an unfavorable clinical trait. However, more recent evidence suggests that the abolishment of normal circadian blood pressure rhythm is not always a solid predictor of adverse cardiovascular events and needs to be interpreted in the light of each patients' individual characteristics. Physicians treating hypertensive patients with adverse nighttime blood pressure profiles often face the dilemma of chronotherapy. This has been a blurred field for years, yet very recent evidence from appropriately designed studies attempts to shed light on this puzzling question. As 24-h ambulatory blood pressure monitoring is being increasingly recommended and applied in real-world practice for the diagnosis and monitoring of hypertension, information on nighttime blood pressure and nocturnal dipping profile is collected but is not always easy to interpret.

Assessing skin microcirculation in patients at cardiovascular risk by using laser speckle contrast imaging. A narrative review.

Skin tissue holds a prominent role in microcirculatory research as an easily accessible vascular bed for the noninvasive evaluation of microvascular function. Skin microvascular changes have been associated to alterations in distinct target organs and vascular beds, reinforcing the hypothesis that skin microcirculation can be used as a model of generalized microvascular function. In addition, skin microvascular dysfunction has been documented in cardiovascular disease and patients of increased cardiovascular risk where it has been associated with multiple cardiovascular risk factors, rendering it a candidate surrogate marker of vascular damage. Laser speckle contrast imaging (LSCI) is a noninvasive, dynamic laser technique that allows assessment of skin microvascular function (SMF) by obtaining two-dimensional maps of the skin perfusion in real time with high spatial and temporal resolution and, most importantly, with the highest reproducibility compared to other laser methods. An ever-increasing number of studies using LSCI is confirming evidence of impaired SMF in several cardiovascular risk groups, therefore expanding its application in microvascular research and showing its potential clinical utility. This review attempts to present the growing importance of SMF in cardiovascular research and the emergence of LSCI technique as a robust imaging modality with a promising role to explore skin microvascular physiology. After a short description of the relevant technique and its main principle of function, we have also opted to present the most up to date studies using LSCI for the investigation of SMF in patients with cardiovascular disease as well as various groups of increased cardiovascular risk.

Anaplastic testicular seminoma presenting as a hydrocele, in a 36-year-old patient with a family history of anaplastic seminoma.

Testicular cancer is the solid tumor with the greatest incidence in men between 15 and 44 years old. Its main histological type is germ cell tumor, that is divided into seminomatous and non-seminomatous tumors. Seminoma, consisting 55% of testicular cancer, manifests in the fourth decade of men's life and a rare type of it is the anaplastic seminoma (5% to 15% of testicular seminoma). Diagnosis is based on clinical examination, testicular ultrasound, magnetic resonance imaging, tumor markers measurement and pathological examination, while treatment of choice is radical orchiectomy, with or without retroperitoneal lymphadenectomy, potentially followed by radiotherapy or chemotherapy. We present the case of a 36-year-old male patient, whose father suffered from anaplastic seminoma and visited the hospital due to a painless hydrocele. The testicle was swollen and hard on palpation, while cytological examination of the drained fluid detected neoplasm, potentially seminoma. Tumor markers measurement, as well as abdominal and pelvic computerized tomography scans, were evaluated and the patient was staged as IIA, according to the American Joint Commission on Cancer. Radical orchiectomy with high ligation of the seminal vesicle was performed and the pathological examination showed anaplastic testicular seminoma. Postoperatively, four cycles of chemotherapy with bleomycin, etoposide and platinum (BEP) were performed and no signs of recurrence were present after 1 year. In conclusion, anaplastic seminoma has a good prognosis and is suggested to be treated with radical orchiectomy, with or without retroperitoneal lymphadenectomy, potentially followed by radiotherapy or chemotherapy.

Hemobilia Caused by Arterioportal Fistula Following Percutaneous Liver Biopsy Complicated by Acute Cholecystitis and Review of the Literature.

We present a case of a 44-year-old male with chronic hepatitis B that visited the Emergency Department due to epigastric pain after a liver biopsy. The ultrasonography revealed signs of bleeding in the bile ducts. and angiography visualized an arterioportal fistula. Selective right hepatic artery branch embolization was performed, and the bleeding was controlled. Although, the clinical picture was initially improved, the patient presented later with acute abdomen, obstructive jaundice and fever. The patient underwent cholecystectomy with bile duct exploration and placement of a Kehr's T tube in the common bile duct. The postoperative course was uneventful. We also review the relevant literature concerning arterioportal fistula manifested as hemobilia as well as acute cholecystitis occurring after hemobilia.

Blunted Microvascular Reactivity in Psoriasis Patients in the Absence of Cardiovascular Disease, as Assessed by Laser Speckle Contrast Imaging.

Psoriasis is associated with accelerated rates of cardiovascular disease (CVD). Laser Speckle Contrast Imaging (LSCI) is a novel, non-interventional technique for the dynamic assessment of microvascular endothelial dysfunction, which represents an early precursor of CVD. We investigated whether skin microvascular reactivity is impaired in psoriasis and whether an association exists with large artery stiffening. Skin microvascular reactivity was assessed with LSCI combined with post-occlusive reactive hyperaemia protocol in psoriasis patients and controls in the absence of established CVD. Arterial stiffness and central hemodynamics were assessed throughout a whole 24 h period with the Mobil-O-Graph device. Most LSCI indices of microvascular reactivity were impaired in psoriasis patients (n = 90) compared to controls (n = 45) [baseline flux; occlusion flux; peak-to-baseline magnitude; baseline cutaneous vascular conductance (CVC); percentage increase in CVC, p < 0.001 for all comparisons]. In multivariate analysis, psoriatic disease predicted the above markers independently of classical CVD risk factors. Augmentation index, peripheral pulse pressure, and central systolic/diastolic blood pressure correlated with LSCI microvascular responses in the study population (n = 135). Pulse wave velocity significantly correlated with nearly all LSCI parameters, while the association with baseline flux was independent of CVD risk factors and psoriatic disease in multivariate analysis (beta = 0.096, p = 0.039). This study provides evidence of altered skin microvascular responses in psoriasis by use of LSCI, and interaction with macrovascular dysfunction, before the establishment of overt CVD. A non-interventional approach of skin microcirculation with LSCI might be used as an early indicator of vascular health in psoriasis.

Conservative treatment of Boerhaave's syndrome in an octogenarian complicated with late distal esophageal stenosis and successfully treated by stent placement.

An 83-year-old female patient presented to the Emergency Department with shortness of breath, difficulty swallowing and left-sided chest pain following a vomiting attempt. A rupture in the left lower third of the esophagus, with hydropneumothorax, pneumomediastinum, and subcutaneous emphysema was revealed by chest X-ray, thoracic computed tomography scan, and contrast esophagography. The patient was successfully treated conservatively with closed thoracostomy, intravenous fluids, parenteral nutrition, and broad-spectrum antibiotics coverage. Following the successful conservative treatment, the patient developed a distal esophageal stenosis which was treated with an intra-esophageal self-expanding stent.

Una paciente de 83 años acudió al Servicio de Urgencias con disnea, dificultad para tragar y dolor en el lado izquierdo del pecho tras un intento de vómito. Una rotura en el tercio inferior izquierdo del esófago, con hidroneumotórax, neumomediastino y enfisema subcutáneo fue revelada por radiografía de tórax, tomografía computarizada de tórax y esofagografía con contraste. El paciente fue tratado con éxito de manera conservadora con toracostomía cerrada, líquidos intravenosos, nutrición parenteral y cobertura de antibióticos de amplio espectro. Tras el exitoso tratamiento conservador, el paciente desarrolló una estenosis esofágica distal que fue tratada con un stent autoexpandible intraesofágico.

Transdiaphragmatic Intercostal Hernia-An Unusual Hepatic Injury After a Car Accident: A Case Report and Review of the Literature.

Transdiaphragmatic intercostal hernia, in which the abdominal contents of the hernia protrude through the diaphragm and the thoracic wall defect. is a very rare type of hernia with only a few cases having been reported in the literature. That type of hernia is usually manifested in male patients after trauma, penetrating or blunt. It is frequently presented with a palpable thoracic mass and pain. The indicated treatment is surgery. We present the case of a 60-year-old female admitted to the hospital after a car accident and suffered multiple rib fractures (6th, 7th, 8th right ribs / 7th, 8th, 9th left ribs), as well as flail thorax, hemothorax bilaterally, left subcutaneous emphysema and swelling of soft tissues of the right lateral thoracoabdominal wall. CT scan revealed herniation of hepatic parenchyma and intestinal loops into the thorax. The patient was treated surgically, and his postoperative course was uneventful. We also review the relevant literature concerning this transdiaphragmatic, intercostal hernia and identify 42 cases. Transdiaphragmatic intercostal hernia is a rare condition, usually manifested in male patients after trauma, penetrating or blunt. It is frequently presented with a palpable thoracic mass and pain. The indicated treatment is surgery.
