Abstract
PURPOSES Knowledge of visual analog scale (VAS) pain assessment for transoral endoscopic thyroidectomy vestibular approach (TOETVA) is limited. The purpose of this analysis was to classify the postoperative discomfort scores in patients undergoing TOETVA compared to open thyroidectomy. METHODS Observational clinical study of patients who underwent thyroidectomy by VAS pain assessment from September 2016 to March 2017. Patients were stratified into two groups: patients eligible for TOETVA (Group TOETVA) and non-candidates for endoscopic intervention (open thyroidectomy approach-OTA). VAS was recorded in the recovery room, at 24 h, + 2, + 5, + 15, + 30, + 90 days, and 6 months after surgery. Pain assessment was stratified in VAS-lower lip, VAS-chin, VAS-jaw, VAS-anterior neck, VAS-cervical/back, VAS-swallowing, VAS-brushing, VAS-speaking, and VAS-shaving. Secondary outcome assessed were analgesic rescue dose, morbidity, operative notes, hospital stay, and histopathology. RESULTS 41 TOETVA and 45 OTA constituted the analysis. There were differences between the TOETVA and OTA for age, gland volume, mean nodule diameter, coexistence thyroiditis, bilateral procedures, and use of drain. Operative time was longer in TOETVA. Results indicated that TOETVA was associated with reduced neck, cervical back, and swallowing VAS scores in the 24 h after surgery. Conversely, jaw and brushing teeth resulted in higher VAS score in TOETVA group. OTA patients never experienced lower lip or chin pain. The use of rescue analgesics did not differ between the two groups. CONCLUSIONS VAS was used to measure treatment outcome in TOETVA. VAS scores achieved overall a minimal clinical importance difference from the two procedures. There appears to be both a short- and long-term different range of interpretations of pain between TOETVA and OTA.

Tailored-BODIPY/Amphiphilic Cyclodextrin Nanoassemblies with PDT Effectiveness. LANGMUIR : THE ACS JOURNAL OF SURFACES AND COLLOIDS 2018; 34:8639-8651.

Abstract
Amphiphilic cyclodextrins (aCDs) are an intriguing class of carrier systems which, recently, have been proposed to deliver porphyrinoids and anticancer drugs or combined dose of both for dual therapeutic applications. The design of nanoassemblies based on aCD and photosensitizers (PSs) aims to preserve the photodynamic therapy (PDT) efficacy of PS, reducing the tendency of PS to self-aggregate, without affecting the quantum yield of singlet oxygen (1O2) production, and, not less importantly, minimizing dark toxicity and reducing photosensitization effects. With this idea in mind, in this paper, we focus on nanoassemblies between a non-ionic aCD (SC6OH) and halo-alkyl tailored iodinated boron-dipyrromethenes (BODIPY) dye, a class of molecules which recently have been successfully proposed as a stimulating alternative to porphyrinoids for their high photodynamic efficacy. Nanoassemblies of BODIPY/aCD (BL01I@SC6OH) were prepared in different aqueous media by evaporation of mixed organic film of aCD and BODIPY, hydration, and sonication. The nanostructures were characterized, measuring their hydrodynamic diameter and ξ-potential and also evaluating their time-stability in biological relevant media. Taking advantage of emissive properties of the not-iodinated BODIPY analogue (BL01), nanoassemblies based on aCD and BL01 were investigated as model system to get insight on entanglement of BODIPY in the amphiphile in aqueous dispersion, pointing out that BODIPY is well-entrapped in monomeric form (τ ≅ 6.5 ns) within the colloidal carriers. Also morphology and fluorescence emission properties were elucidated after casting the solution on glass. BL01@SC6OH is easily detectable in cytoplasm of HCT116 cell lines, evidencing the remarkable intracellular penetration of this nanoassembly similar to free BODIPY. On the same cell lines, the photodynamically active assembly BL01I/aCD shows toxicity upon irradiation. Despite the fact that free BL01I is more PDT active than its assembly, aCD can modulate the cell uptake of BODIPY, pointing out the potential of this system for in vivo PDT application.

Abstract
OBJECTIVE Cardiac catheterization (CC) is a life-threatening procedure in adult patients. Complicated by idiopathic arterial pulmonary hypertension (IPAH), there is a potential risk of central nervous system (CNS) damage. We measured serum levels of a well-established brain damage marker, namely S100B, collected before, during and after CC in adult patients in whom the nitric oxide (NO) test had been performed. MATERIAL AND METHODS In 12 adult patients who had undergone CC for IPAH diagnosis, we recorded clinical and standard monitoring procedures (laboratory variables and echocardiographic patterns) and serum concentrations of S100B before (time 0), during (time 1) and after the NO test (time 2) and at 24 h after (time 3) the procedure in samples obtained from the systemic and pulmonary circulation. Patients were subdivided into NO test responders (n=6) and non-responders (n=6). Neurological evaluation was performed at admission and at discharge from hospital. RESULTS Adult patients subjected to CC showed no overt neurological injury at discharge from hospital. No significant differences (p > 0.05 for all) in S100B serum levels between groups at times 0, 1 and 3 have been shown independently from the sampling site. It was noteworthy that the concentration of protein in the responders group at time 2 was significantly decreased (p < 0.05, for all) compared to the responder group and to baseline values. A significant correlation was found between arterial oxygen partial pressure and individual S100B concentration in the pulmonary and systemic bloodstream in the entire study group (R = -0.66 and R = 0.71, respectively; p < 0.05, for both). CONCLUSIONS The data suggest that S100B protein assessment, as well as the NO test, may be useful when monitoring possible CNS damage during CC in patients with IPAH, and may also be valuable in relation to brain functions, especially when performed as an emergency procedure in severely hypoxic patients.

Abstract
Turner's syndrome is generally characterised by bilateral gonadal disgenesis, short stature and inadequate sexual development secondary to anomalous karyotype. The purely otorhinolaryngoiatric pathology considerably influences the symptomatological features in Turner's subject and this is based on possible morphologically structured anomalies in the external, middle and inner ear, but also on the oral cavity and pharynx. From this there is evidence of otological emergence on a phlogistic infectious basis with remarkable long-term repercussion on the hearing process. Otofunctional evaluation in 21 Turner's syndrome patients shows predominance of conductive hearing loss (42.8%), proven through evidence of otitis media (33.3%) and chronic otitis media (9.5%). This, therefore, demands an attentive audiologic monitoring related to the possible development of chronic forms or cholesteatoma and the possible rehabilitative-prothesis procedure.

Abstract
Donald Winnicott (1896-1971), specialist in children's diseases, psychology and psychotherapy, tried to put together his experience in all these fields. His theories can be put between the orthodox psychoanalytic thought and a "relational" paediatrics. He made his research on the "global reality" of child rather than being interested in the "internal objects". Both the orthodox analysts, who condemned his theories, and the specialists in children's diseases, who didn't recognize the scientific aspect of his genius, criticised and opposed Winnicott. Even if sometimes his theories have not an organic unity, they are the result of very detailed clinical observations, which are supported by a large experience with children at the Paddington Green Children Hospital and the Queen's Hospital for Children in London. With "transition", Winnicott means an intermediate development area between the psychic and external reality. There, we can find the "transitional object", which is the first element leading the child to face the external reality through the creation of symbols. Winnicott goes over the idea of the binomial mother-child, intended as instinctive development, and underlining the importance of real experiences. In his opinion, in the child development one has to stress the concept of "need" instead of that of "desire". A good environment and the empathic contact with "a fairly good mother", cause the passage from the primary narcissism to the object relationships. A fairly good mother must be able to perform holding, handling, and object presenting. Her duty is that of gradually undeceiving, and to do it she must give a sufficient opportunity of illusion. The mother, offering the right opportunity of illusion, puts the basis of symbols. Subsequently, she will go on a gradual disillusion. Winnicott disagrees Klein's ideas by stating that "playing is therapeutic in its own aspect", seeing it as a potential space between mother and child, which will become the place of analysis and transfer and, after on, that of cultural experience.

Abstract
The kit described is for air-dropping for immediate use in the surgical treatment and resuscitation of burn victims in major emergencies when there is no direct access to the disaster area by rescue teams or vehicles. The kit can also be used to make up for deficiencies in medicines or medical materials in remote hospitals that have admitted people with severe burns who are not immediately transferable to other hospitals.

Abstract
Intranasal desmopressin represents the treatment of choice in Central Diabetes Insipidus. Nevertheless, this route of administration bears some practical disadvantage, linked to either difficult delivering technique, or the status of nasal mucose. The antidiuretic effectiveness of oral desmopressin has been recently demonstrated, both in experimental animals and in man. In our study we compared oral vs. intranasal desmopressin efficacy in 13 patients affected by Central Diabetes Insipidus. The results show that the peroral administration of Desmopressin at a mean dose of 500-600 micrograms/die determines an antidiuretic effect comparable to that of intranasal route, without affecting body weight, arterial pressure and chemical analysis. Side effects, generally limited to the first week of treatment, were described (nausea, vomiting, headache, dizziness [corrected], bitter taste, epygastralgia, asthenia, epystassis), inducing 4/13 patients to withdrawal the trial.

Abstract
The monoclonal antibodies (MAbs) obtained in mice immunized with human PRL coupled to an anti-PRL MAb were screened for their ability to distinguish the glycosylated (G-) and nonglycosylated (NG-) forms of PRL. The 431-29 MAb exhibited high affinity binding for NG-PRL but little or no cross-reactivity to G-PRL. Using this antibody in conjunction with other MAbs which equally recognized both forms, we developed 2 immunoradiometric assays which were used to determine the amount of G- and NG-PRL in plasma. In 85 normal subjects, NG-PRL baseline levels averaged 6.6 +/- 3 micrograms/L, and represented 76 +/- 8% of the total PRL immunoreactivity. In 74 pregnant women, this proportion was significantly higher during the last 2 trimesters (84 +/- 4% and 85 +/- 6%), as compared to the first trimester (76 +/- 7%). In 6 healthy volunteers studied over 24 h, 79% of the NG-PRL peaks detected using the cluster algorithm occurred concomitantly to a G-PRL peak. The mean NG-PRL/PRL ratio was significantly higher during NG-PRL pulses (81 +/- 9%) than during valleys (71 +/- 12%). Similarly, this ratio was significantly increased during TRH or metoclopramide stimulated PRL secretion (to 88 +/- 7% and 86 +/- 6%, respectively). We conclude that 1) NG-PRL is the predominant immunoassayable form of PRL in plasma; 2) both G- and NG-PRL are cosecreted but NG-PRL is the main PRL form released during spontaneous or pharmacologically induced PRL secretion.

Abstract
A ten-year experience on 36 patients bearing macroprolactinomas (MP) and 86 others bearing microprolactinomas (mP) is reported in this study. Different therapeutical approaches were used: 1) trans-sphenoidal surgery in 24 patients with MP and in 25 with mP; 2) medical therapy with the oral form of bromocriptine (BRC) in all the 24 patients with MP previously subjected to surgery, in 48 patients with mP ab initio, and in 16 out of 25 patients with mP previously subjected to surgery; 3) medical therapy with the long-acting injectable forms of BRC in 12 MP- and 13 mP-bearing patients, and 4) conventional radiotherapy in 12 of the 24 patients with MP previously subjected to surgery. The follow-up, performed five years after surgery, showed that: a) all the 24 patients with MP but one had normal PRL levels during BRC administration, with a rebound of hyperprolactinemia in all cases after withdrawal; b) during the treatment BRC caused normalization of PRL in 15 of the 16 mP-bearing patients surgically treated and in all the 48 mP-bearing patients only treated with BRC; c) in 20 of the 25 patients the treatment with injectable retard BRC caused the normalization of plasma PRL and the shrinkage of the tumor mass in all the patients with MP but one, as revealed by seriate CT scans. In conclusion, the surgical treatment of prolactinomas was ineffective to normalize plasma PRL levels in most patients whereas BRC, in standard or in retard forms, was able to normalize plasma PRL levels, reduce the tumoral mass and preserve the pituitary residual tissue. BRC should be, therefore, used as first choice therapy both for MP and mP.

Abstract
The effectiveness and long-term tolerability of a new formulation of bromocriptine with slow gastrointestinal release (Parlodel SRO) has been evaluated on ten patients with macroprolactinoma, seven patients with microprolactinoma and five patients with nontumoral hyperprolactinemia during a period of 1-30 months. Six out of ten macroprolactinoma-bearing patients obtained a rapid normalization of plasma PRL levels with reduction of the tumor size recorded by CT scan follow-up. Four of six microprolactinomas and all the five nontumoral hyperprolactinemic patients became normoprolactinemic with recovery of gonadal functions while in two other microprolactinomas Parlodel SRO significantly reduced plasma PRL levels with restoration of menses. Only in two patients the treatment was withdrawn for the appearance of side effects. In conclusion, Parlodel SRO is an effective drug in the management of tumoral and nontumoral hyperprolactinemia. The good long-term tolerability together with the hypoprolactinemic activity makes this drug a very good choice therapy in hyperprolactinemic syndromes even in case of poor tolerability to the standard formulation of the drug.

Abstract
This study reports a case of allergy to ergot-derived drugs in a patient with a prolactin (PRL)-secreting microadenoma. The anamnesis revealed allergic reactions to the administration of analgesics and antibiotics. The administration of dopamine agonist drugs, such as bromocriptine (BRC; 2.5 mg) or lisuride (0.2 mg), induced after a few minutes the appearance of nausea, vomiting, postural hypotension, headache, edema of the glottis with dispnea and acroedema. The edemas disappeared a few hours after the administration of antihistaminic drugs while nausea, vomiting, postural hypotension and headache persisted for a few days. Therefore, the patient was tested with another dopamine agonist non-ergot-derived drug, quinagolide (CV 205-502), which did not cause side effects or allergic reactions. Furthermore, not only was the responsiveness to the drug optimal but it also normalized the PRL levels, and menses reappeared after more than a 5-year amenorrhea. This report suggests that ergot-derived drugs, such as lisuride and BRC, seldom induce allergic reactions apart from common side effects. Consequently, the feasibility of using a new drug with a different molecular structure (non-ergot derived) effective in the therapy of hyperprolactinemic syndromes represents a good alternative to conventional therapy.

Abstract
The aim of this study was to evaluate plasma thyrotropin (TSH), prolactin (PRL) and growth hormone (GH) responses to the TSH-releasing hormone (TRH) test and to a combined arginine-TRH test (ATT-TRH) in 10 normal subjects and in 15 acromegalic patients. In controls, TSH responsiveness to TRH was enhanced by ATT (p less than 0.001). When considering the 15 acromegalic patients as a whole, no significant difference in TSH responses was detected during the two tests. However, patients without suppression of plasma GH levels after oral glucose load showed an increased TSH responsiveness to the ATT-TRH test if compared to TRH alone (p less than 0.025), while patients with partial suppression of plasma GH levels after glucose ingestion showed a decreased TSH responsiveness to ATT-TRH (p less than 0.05). No difference was recorded in PRL and GH responses, evaluated as area under the curve, during TRH or ATT-TRH tests in controls and in acromegalics. In conclusion, (1) normal subjects have an enhanced TSH response to the ATT-TRH test and (2) acromegalic patients without suppression of GH levels after oral glucose load show a TSH responsiveness to the ATT-TRH test similar to that of controls, while acromegalics with partial GH suppression after oral glucose load have a decreased TSH responsiveness to the ATT-TRH test. These data suggest that acromegaly is a heterogeneous disease as far as the somatostatinergic tone is concerned.

Abstract
Bromocriptine, a D2 receptor agonist, has been widely used in tumoral and non-tumoral hyperprolactinemia, in reducing both plasma prolactin levels and in restoring fertility and/or menses in most patients. In this study a comparison between the injectable repeatable and the oral slow release formulations of bromocriptine (Parlodel LAR and Parlodel SRO) is reported, with respect to their effectiveness, tolerability and safety. Eleven patients with hyperprolactinemia, submitted to both treatments, were studied for a period of 1-24 months. Among the four patients with macroprolactinoma, three reached normoprolactinemia without complaining of side-effects, with both formulations, while the remaining patient became intolerant of the oral form after 1 year, and is presently being treated with the injectable formulation without presenting any side-effects. Among the five patients with microprolactinoma, two patients had a good response to both drugs; two patients did not reach normoprolactinemia with the injectable formulations, but a progressive decrease of prolactin levels was obtained with Parlodel SRO therapy, and the remaining patient was completely intolerant of the oral form without complaining of side-effects with Parlodel LAR. Two patients had non-tumoral hyperprolactinemia: one was intolerant of both drugs and one tolerated both formulations very well. In conclusion, Parlodel LAR and Parlodel SRO are very effective compounds in the medical treatment of hyperprolactinemic syndromes. The availability of these differing formulations improves the medical therapy, allowing a better choice of therapeutic regimen according to the effectiveness of, and tolerability to, the different drug formulations. In this way also, with poorly tolerant patients, it is possible to choose the better tolerated and more effective formulation of the drug.

Abstract
Ciprofloxacin (CIP) and metabolite concentrations in lung tissue, parietal pleura and bronchial tissue were assessed in 43 adult patients who underwent lung surgery. A single oral dose of CIP was given for prophylaxis of bacterial infections. Two to 6 h prior to tissues sampling, 23 patients received 250 mg and 20 subjects 500 mg of the substance. Blood plasma samples were obtained at the same time as the lung tissue samples. CIP and its metabolites were assayed chemically by high-pressure liquid chromatography (HPLC). After 250 mg CIP, the individual lung tissue CIP concentrations during the 2- to 6-hour post-dose period ranged from 0.5 to 4.8 mg/kg. In 20 of the 23 lung samples, the CIP concentrations were above 1 mg/kg. After 500 mg CIP, the corresponding lung CIP concentrations ranged from 1.6 to 6.0 mg/kg. The CIP lung concentrations were, irrespective of the dose size, between 2 and 7 times higher than the simultaneous blood plasma concentrations. This indicates an excellent penetration of CIP and its metabolites into lung tissue. Bronchial tissue was obtained in 9 cases. Penetration into bronchial mucosa tissue was good as well, as indicated by tissue/plasma ratio values between 1.5 and 4.4. Individual CIP concentrations in the patients given 250 mg CIP, ranged from 1.0 to 1.6 mg/kg. In the patients who received 500 mg, the range was from 1.7 to 3.4 mg/kg. Tissue/plasma ratio values between 0.8 and 2.1 indicated that penetration to pleural tissues was good as well. Metabolite concentrations in all of the tissues assayed (lung, bronchial mucosa, pleural tissue) were low when compared to the concentrations of CIP. The concentrations in lung, pleural and bronchial tissue will probably permit low doses in the treatment of most respiratory tract infections. The broad spectrum of antibacterial activity, the good tissue penetration, chemical stability and the good safety record of the substance means that the drug is potentially a useful agent for perioperative antibiotic prophylaxis.

Abstract
This study compares two sources of information on prior use of antibiotics in children with acute lower respiratory tract infection. The presence of antibiotics in respiratory specimens complicates recovery of bacterial pathogens and the selection of appropriate antibiotic treatment. The first source of information is the parents, who are asked about recent use of antibiotics by their child. The second source is an agar diffusion assay that detects antibiotics in urine specimens. In Argentina, where antibiotics are readily available without prescription, parental information about a child's recent antibiotic therapy was found to be relatively reliable only when their answer was affirmative.

Abstract
Five patients with PRL-secreting macroadenoma and nine patients with PRL-secreting microadenoma or idiopathic hyperprolactinaemia were treated with monthly administrations of long-acting bromocriptine suitable for repeatable injections (Parlodel LAR) for 1-12 cycles of treatment. A significant shrinkage of tumour mass and the recovery of visual field defects were observed in patients with macroprolactinoma. Plasma PRL levels decreased to 16.8 and 18.1% of pretreatment values, in macroprolactinoma and idiopathic or microadenomatous hyperprolactinaemic subjects, respectively, during the first cycle of treatment, reaching the normal range in three patients of each group. During the following cycles of treatment, two patients with macroprolactinoma and one patient with idiopathic or microadenomatous hyperprolactinaemia became normoprolactinaemic. Adverse reactions generally did not last beyond the first days of administration and decreased with the progression of the treatment. In conclusion, its effectiveness and the fact that it is well tolerated, may suggest that this form of bromocriptine may be used as a first therapeutic approach for patients with PRL-secreting adenomas, particularly when shrinkage of a macroadenoma is urgently required.

Abstract
The determination of calcium content in human bone tissue is very useful in metabolic diseases of bone, such as renal osteodystrophy, osteoporosis, hyperparathyroidism, and osteomalacia of diverse etiology. The PIXE technique allows calcium to be directly determined in bioptic tissue sections properly, sampled for histological optical and/or electron microscopy examination.Bone semithin sections (3 μm thick, 4×4 mm(2) dimensions), cut by ultramicrotome and deposited onto polyvinyl acetate films, underwent PIXE analysis using the CISE set-up. Histomorphometric (after standard staining), evaluation of calcified bone volume (CBV) in absolute value allows calcium density to be determined. A total of nine bone biopsies were analyzed (three sections each) obtaining values ranging between 352 and 482, with an average value of 421.5±15.3 (M±SE) μg/μL, in good agreement with literature data (obtained by AAS technique on dissected bone samples).The aim of this paper is to emphasize the usefulness, of combined PIXE and histomorphometric techniques for the study of calcium content in bone tissue in both healthy and diseased bones.

Early protection to Junín virus of guinea pig with an attenuated Junín virus strain. Acta Virol 1985; 29:334-7. [PMID: 2413752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/31/2022]
Abstract
Inoculation of guinea pigs with attenuated XJO Junín virus (JV) strain confers protection against challenge with pathogenic XJ-JV strain starting as early as 3 days post infection (p.i.). The protection increased continuously up to 100% by 30 days p.i. Neither stimulation of non-specific cell mediated mechanisms by previous BCG sensitization nor circulating interferon (IFN) seemed essential for such protection. The early detection of the virus in guinea pig organs considered the site of primary JV multiplication suggests that early resistance phenomenon was attributed mainly to direct viral interference.

Abstract
Starting from one case of Gardner's syndrome of their own observation, and in light of Watne's results, the authors argue that in the syndrome just named--and in familial polyposis in a broader sense--genetic factors do not play a predominant role; rather, polyps seem to result from the prolonged action of noxious agents. At any rate, said action can be neutralized, and possibly prevented either with a surgical modification of the distal gut or by treatment with a chemical substance identified as ascorbic acid. In view of these considerations, the authors recommend preventive medical therapy.

Abstract
Since estrogen has been shown to reduce aortic medial hypertrophy in hypertensive rats, a naturally occurring estrogen compound, estradiol, was studied for its ability to suppress the intimal hyperplasia which follows vessel transection and anastomosis. Suture lines and adjacent abdominal aortas were examined by light and electron microscopy 1 month after surgery, in 23 rabbits. Test animals were given 200 microgram of Depoestradiol I.M. weekly, starting 3 days preoperatively. Control animals were similarly manipulated but received no estrogen. Control animals showed striking intimal thickening over the sutures, in contrast to the estrogen-treated group in which there was significantly less growth of corresponding tissue (p less than 0.01).

Abstract
The authors, on the basis of their experience on two cases of cardiac tamponade, and from the revision of literature, retain that immediate thoracotomy, followed by re-examination of the pericardial sac and myocardiorrhaphy, represents a treatment preferable to the evacuant pericardiocentesis, confining the latter only to diagnostic conditions and immediate decompression in cases which arrive in unequipped places.
