Improper communication starts arterial hypertension in a vulnerable individual

Background: People interact with or without words and sounds through their energy, and their appearance makes us think of them. People’s communication by terms represents a common and convenient channel to exchange ideas and deal with problems. Collaboration luxury relaxes and improves individual well-being; ill-mannered people interactions act in opposite directions. Provocative and scandalous debates go before various mental disturbs, following physical complaints according to existing fragile areas. Aim: To reveal the influence of communication skills on blood vessel control and how improper communication starts arterial hypertension in a vulnerable individual. Material& Method: A qualitative study was performed by the author in the community from 2008 to 2023, relating to the people’s interaction influence on their health. People’s inappropriate communication effects on the individual were noticed, then corrected. Findings: man, aged 68, occasionally experienced unpleasant cooperation with some members of his large family. Each time, after offensive attitudes and forceful disputes, he presented tachycardia and increased blood pressure: 155/90 to 167/95 mmHg. On November 2022, following a violent discussion with a family member, he presented headache, high blood pressure, 180/103 mm Hg, tachycardia, and vertigo. Patient’s family medical history: Parents, brothers, and sisters: arterial hypertension. Patient’s medical history: Transient arterial hypertension, from 2009; permanent arterial hypertension: 2022; atrial arrhythmia, 2022.

Triptorelin-Induced Delayed Transient Arterial Hypertension: A Case Series with Review of Literature

Background: Gonadotropin-releasing hormone analogs (GnRHas) such as triptorelin have been found to be effective and safe in the suppression of central precocious puberty (CPP). Only minor and transient side effects have been reported with depot preparation used in children. Clinical Description: We present three children with CPP who developed late onset hypertension 18–24 months after starting triptorelin, a long-acting GnRHa depot preparation. The secondary causes of hypertension were ruled out on the basis of clinical findings, appropriate blood tests, echocardiography, and abdominal ultrasound. Management and Outcome: After starting therapy with GnRHa, the children were evaluated routinely every 2–3 months for the 1st year, then every 6 months. They developed hypertension between 18 and 24 months after starting triptorelin. While therapy with triptorelin was stopped in all three children, only one of them was prescribed antihypertensive drug. The hypertension resolved gradually after discontinuation of triptorelin in all the children and antihypertensive was also omitted in the single case. Conclusion: Hypertension may be an adverse effect of triptorelin therapy and thus regular monitoring of blood pressure in children undergoing therapy with this drug for CPP is warranted.

The prognostic value of transient arterial hypertension in patients with chronic heart insufficiency and preserved left ventricular ejection function

The study included 169patients (74 men and 95 women) with CHI (mean age 56,3±10,9 yr). All of them had PEF higher than 50%. 105 patients had FCII CHI, 64 ones FCIII CHI. Stage IIA was documented in 136 and stage IIB in 33 patients. Duration of the study 24 months. The combined end point included non-fatal myocardial infarction and cardiovascular death. Arterial hypotension at office AP was diagnosed in 16 (9,5%) patients, transient arterial hypotension based at 24 hr AP monitoring in 104 (61,6%) patients. A total of 8 combined end points were documented during the study period. All these patients had transient systole-diastolic and/or systolic arterial hypotension . No myocardial infarction or lethal outcome developed in CHI patients without episodes of arterial hypotension (x=4,28, р=0,04). 24 hr AP monitoring in CHI-PEF patients permits to significantly increase the frequency of detection ofpotentially dangerous changes of AP. Transient arterial pressure occurs in 61.6% of the FCII-III CHI-PEF patients. Transient systole-diastolic arterial hypotension significantly increases the risk of non-fatal myocardial infarction and cardiovascular death in CHI-PEF patients

Arterial hypertension after surgical closure of omphalocele and gastroschisis

Arterial hypertension has been reported as a complication of surgical closure of an abdominal wall defect. No report studying the incidence, the characteristics and the clinical significance of hypertension after surgical correction of an omphalocele or gastroschisis has been published so far. The medical records of all newborns with surgically corrected gastroschisis or omphalocele identified in two centers were retrospectively evaluated. Arterial hypertension was defined as a mean daily systolic and/or diastolic blood pressure value higher than the 95 percentile for age and/or weight, according to literature data. The timing of surgery, weight gain, plasma creatinine and the use of diuretics or vasoactive drugs were compared between the groups with and without hypertension. Seventy-two patients were identified and included in the study, 29 with omphalocele and 43 with gastroschisis. Those with omphalocele were born at a mean age of 37.3+/-2.6 weeks with a mean birth weight of 2,971+/-715 g, and those with gastroschisis were born at 36.1+/-2.0 weeks with a mean birth weight of 2,527+/-498 g. Blood pressure values of 66 patients were available for analysis. Of the omphalocele patients, 46.2% (12/26) developed systolic hypertension, compared to 17.5% (7/40) of the patients with gastroschisis (P =0.024). Hypertension was always transient, lasting an average of 4 and 1 day in the omphalocele and gastroschisis groups, respectively. Two patients with omphalocele were given anti-hypertensive therapy. There was no difference between patients with or without hypertension regarding weight gain, use of vasoactive drugs or diuretics, mean weekly creatinine values or the timing of surgery. Newborns with an abdominal wall defect frequently present with transient arterial hypertension. Hypertension occurs significantly more often, is more severe and lasts longer in patients with omphalocele than in patients with gastroschisis. In both groups, hypertension is transient and rarely requires therapy. The cause of hypertension remains unclear.

EFFECT OF DIASPIRIN CROSSLINKED HEMOGLOBIN (DCLHb HemAssist™) DURING HIGH BLOOD LOSS SURGERY ON SELECTED INDICES OF ORGAN FUNCTION*

The safety of the hemoglobin based oxygen carrier diaspirin crosslinked hemoglobin (DCLHb) has been reported only in the low (50-200 mg/kg) dose range [Przybelski. R.J.; Daily, E.K.; Kisicki, J.C.; Mattia-Goldberg, C.; Bounds, M.J.; Colburn, W.A. Phase I study of the safety and pharmacologic effects of diaspirin crosslinked hemoglobin solution. Crit. Care Med. 1996, 24 (12), 1993-2000, Bloomfield, E.; Rady, M.; Popovich, M.; Esfandiari, S.; Bedocs, N. The use of diaspirin crosslinked hemoglobin (DCLHb 1996, 95, (3A), A220.]. We conducted a randomized prospective open-label trial of DCLHb and packed red blood cells (PRBCs) in high-blood loss surgical patients to show the effect of 750 ml DCLHb (approximately 1000 mg/kg) on selected indices of organ function. After institutional approval, 24 patients scheduled to undergo elective orthopedic or abdominal surgery, were randomized to receive either PRBCs or 10% DCLHb within 12 hours after the start of surgery. Patients with renal insufficiency, abnormal liver function, severe coronary artery disease (CAD) and ASA physical status > or = IV were excluded. The anesthetic technique was left to the judgment of the anesthesiologist. Autologous predonation and intraoperative blood conservation techniques were utilized as appropriate. The indications for blood transfusion were individualized on disease state, stage of surgery, and plasma Hb concentration. Laboratory studies were obtained preoperatively and up to 28 days postoperatively. Patients were observed daily for development of jaundice, hematuria, nausea, vomiting, gastrointestinal discomfort, cardiac, respiratory, and infectious complications. Organ effects were assessed with urinalysis, creatinine clearance, electrocardiogram (ECG), and a panel of blood and serum laboratory tests. The dose of DCLHb administered ranged from 680-1500 mg/kg (mean = 999 mg/kg). Estimated blood loss was 27 +/- 13 ml/kg and 31 +/- 15 ml/kg in the control and DCLHb groups, respectively. Fewer PRBCs (1.9 +/- 1.2 vs. 3.4 +/- 2.4 units. P = 0.06) were transfused to DCLHb patients on the operative day although this difference was no longer apparent later on. In the DCLHb group, 4/12 patients avoided any allogeneic PRBC transfusion vs. none in the control group (P = 0.09). Systolic, diastolic and mean blood pressure increased moderately after DCLHb for a period of 24-30 hours. There were no occurrences of cardiac ischemia. myocardial infarction, stroke, or pulmonary edema, by clinical or laboratory parameters up to the 28th postoperative day (POD). Seven of 12 (58%) DCLHb patients had yellow skin discoloration vs. none in the PRBC group (P < 0.01). Two of four non-urologic surgery patients developed asymptomatic postoperative hemoglobinuria after DCLHb. Creatinine clearance was unchanged postoperatively. Because of hemoglobin interference, bilirubin, gamma-glutamyl transferase (GGT), and amylase could not be measured reliably on POD1; on POD2. amylase was transiently elevated to 3 times ULN along with mild elevations of bilirubin, transaminases and BUN. Mean total creatine phoshokinase (CPK) peaked at 8 times the upper limit of normal (ULN) in the DCLHb group, compared with less than twice ULN for controls. Three DCLHb patients had prolonged ileus. Two of these patients had postoperative hyperamylasemia, one of whom developed mild pancreatitis. DCLHb did not affect white blood cell count or coagulation tests. Administration of approximately 1000 mg/kg DCLHb was associated with transient arterial hypertension, gastrointestinal side effects, laboratory abnormalities, yellow skin discoloration, and hemoglobinuria. These observations point to opportunities for improvement in future synthetic hemoglobin design.

End-systolic pressure-diameter relation of the left ventricle during transient and sustained elevations of blood pressure.

To assess the effect of transient and sustained variations in cardiac load on the values of the end-systolic pressure-diameter relation (ESPDR) of the left ventricle. We studied 13 dogs under general anesthesia and autonomic blockade. Variations of cardiac loads were done by elevation of blood pressure by mechanical constriction of the aorta. Two protocols were used in each animal: gradual peaking and decreasing pressure variation, the "transient arterial hypertension protocol" (TAH), and a quick and 10 min sustained elevation, the "sustained arterial hypertension protocol"(SAH). Then, we compared the ESDR in these two situations. Acute elevation of arterial pressure, being it "transitory" or "sustained", did not alter the heart frequency and increased similarly the preload and after load. However, they acted differently in end systolic pressure-diameter relation. It was greater in the SAH than TAH protocol, 21.0+/-7.3 mm Hg/mm vs. 9.2+/-1. 2 mm Hg/mm (p<0.05). The left ventricular ESPDR values determined during sustained pressure elevations were higher than those found during transient pressure elevations. The time-dependent activation of myocardial contractility associated with the Frank-Starling mechanism is the major factor in inotropic stimulation during sustained elevations of blood pressure, determining an increase in the ESPDR values.

Intravenous immunoglobulin (IVIg) for the treatment of birdshot retinochoroidopathy

Intravenous polyclonal immunoglobulin (IVIg) treatment has been successfully used in a number of autoimmune conditions. Birdshot retinochoroidopathy (BRC) is a bilateral autoimmune posterior uveitis which, in its progressive form, frequently requires immunosuppressive therapy. We report a clinical study aimed at determining the tolerance and efficiency of IVIg treatment in patients with active BRC. The study was conducted in an open manner. Eighteen patients were included. The initial visual acuity (VA) was =20/30 in 26 eyes, 20/25 in five eyes, and 20/20 in five eyes. IVIg was given as sole treatment at 1.6 g/kg every four weeks for six months, followed by injections of 1.2-1.6 g/kg at six to eight-week intervals. The mean follow-up was 39 months, ranging between 12 and 53 months. The results showed that the final VA of the 26 eyes with an initial VA of =20/30 was increased by two lines or more in 14 eyes (53.8%) and decreased in two (7.7%). Of the five eyes with an initial VA of 20/25, four had improved to 20/20 and one remained stable. Of the five eyes with an initial VA of 20/20, four remained stable and one deteriorated to 20/25. When present, macular edema was improved in half of the eyes on fluorescein angiography. Benign side effects were observed in 12 patients: moderate transient arterial hypertension (7), headache (6), eczematous lesions (6), and hyperthermia (4). The results suggest that IVIg may represent a safe alternative therapy for patients with BRC.

A brief episode of severe arterial hypertension induces delayed deterioration of brain function and worsens blood flow after transient multifocal cerebral ischemia.

Transient arterial hypertension occurs sporadically following cerebral air embolism and may occur during the acute phase of stroke. This study used an animal model of multifocal cerebral ischemia induced by air embolism and reversed by recompression to assess the effect of induced hypertension on the evoked response recovery, local cerebral blood flow, intracranial pressure, and brain water in 19 anesthetized dogs (Canis familiaris). Six received 0.4 ml of air via the internal carotid artery, 8 received intracarotid air and 10 micrograms/kg norepinephrine to produce transient hypertension, and 5 received intracarotid saline and norepinephrine. The average evoked response recovery in the air-only group was 58.3 +/- 7.7% (mean +/- SEM) of control after 4 hours of recompression; the air plus hypertension group recovery was 15.4 +/- 2.7% (p less than 0.01). The final evoked response in the dogs receiving hypertension alone did not differ from control values. Seven of 8 dogs in the air plus hypertension group had very low blood flows; only 1 of 4 in the air-only group had very low flows. The amount of brain water and the intracranial pressure were not detectably different at the end of treatment among all 3 groups. These results support a role for endothelial damage produced by air and hypertension in potentiating the process of postischemic hypoperfusion.

Prolonged nonbacterial meningitis: clinical aspects and cerebrospinal fluid findings

Ten to 28 days after hospital admission cell count and/or total protein concentration showed no decrease or further increase in 33 children (25 boys, 8 girls) between 2 to 15-years of age who suffered from acute aseptic meningitis (causative agents: mumps virus in 9 children, enterovirus in 5 children). Three of these children had cerebral palsy as a possible predisposing factor. The onset of prolonged aseptic meningitis was protracted in some children. At hospital admission the clinical features of this disorder differed not from those in uncomplicated acute aseptic meningitis. In 4 children a one-sided and in 4 patients a doublesided peripheral facial paralysis occurred as a transitory complication. One child showed transient arterial hypertension. EEG was normal in most of the children or revealed a slight general slowing only. Apart from a slight enlargement of the ventricles in 3 children cerebral CT showed no abnormality. Complaints like vertigo, headache, and vomiting persisted for weeks or months in part of the children. During the course of the disease CSF reflected two different reactions: 1. further increase of total protein in combination with a minimal cellular response, affecting 2-10 years old boys and girls equally; protein electrophoresis revealing the pattern of severe blood-CSF barrier disturbance, 2. persistant elevation or further increase of both cell count and total protein occurring nearly exclusively in 6-15 years old boys, associated with the CSF-protein pattern of severe blood-CSF barrier disturbance and of oligoclonal gamma-fractions.(ABSTRACT TRUNCATED AT 250 WORDS)
