[Concordance of medication prescription records in the hospitalised surgical patient]. / Concordancia de los registros de prescripción de medicamentos en el paciente quirúrgico hospitalizado.

INTRODUCTION: Electronic prescription is the prescription system that allows healthcare professionals to send medication prescriptions directly to community pharmacies and the outpatient unit of Hospital Pharmacy Services for dispensing. However, there is difficulty in obtaining a reliable pharmacotherapeutic history in chronic patients through electronic prescription upon hospital admission as a critical point for adequate treatment adaptation. Therefore, the pharmacist as a member of the multidisciplinary team must ensure, through medication conciliation, an adequate transition of care through the correct management of the treatment that the chronic patient requires during their hospitalization. OBJECTIVES: To evaluate the quality of electronic prescription records for routine chronic treatment by analyzing the concordance of the electronic prescription. MATERIAL AND METHODS: Observational, cross-sectional and retrospective study at the General University Hospital of Elche. Hospitalized patients in charge of the Orthopedic Surgery and Traumatology, Urology and Neurosurgery Services in which the responsible doctor requested medication reconciliation by the Pharmacy Service between January 2022 - December 2022 were included. RESULTS: 378 patients, 209 (55.3%) women and 169 (44.7%) men, with a mean age±standard deviation of 71.0±11.6 years and 69.0±11.8 years, respectively. The total percentage of patients with discrepancies in the electronic prescription with respect to the usual chronic treatment was 60.6%, reflecting that only 39.4% of the patients had non-discordant electronic prescriptions. CONCLUSIONS: More than half of hospitalized surgical patients present discrepancies in the medications prescribed in the home electronic prescription, which justifies the importance of treatment reconciliation upon admission carried out by hospital pharmacists.

New cases of accessory and cavitated uterine masses (ACUM): a significant cause of severe dysmenorrhea and recurrent pelvic pain in young women.

BACKGROUND: To raise awareness about the accessory and cavitated uterine masses (ACUM) with functional endometrium as a different entity from adult adenomyosis and to highlight the importance of a correct diagnosis, we studied four new cases of ACUM and 15 cases reported as juvenile cystic adenomyoma (JCA) by reviewing the literature from the last year. This entity is problematic because of a broad differential diagnosis, including rudimentary and cavitated uterine horns; and is generally underdiagnosed, being more frequent than previously thought. METHODS: We report four cases of young women who underwent surgery in our hospital from January to July 2011 after presenting with an ACUM. We also reviewed and tabulated the cases from literature beginning in 2010. Main outcome measures were diagnostic tools, surgical and histopathological findings and improvement of symptoms. RESULTS: The addition of the four cases reported here to the 15 published as JCA raises the total number of cases of ACUMs to 19, which is more than all of the cases reported prior to 2010. In our cases, it is interesting to highlight that one of them also had an adjacent accessory rudimentary tube and another had two ACUMs at the same location. All patients suffered from severe dysmenorrhea and pelvic pain and were young women. Suspicion, transvaginal ultrasound and magnetic resonance image were found to be the best diagnostic tools. Most of the cases were treated by laparoscopic tumorectomy. CONCLUSIONS: ACUMs are generally underdiagnosed and often reported as JCAs but they are not adenomyosis. Early surgical treatment involving the laparoscopic or laparotomic removal of the mass could prevent the usual prolonged suffering of these young women. In our opinion, this entity is a new variety of Müllerian anomaly.

Effect of different doses of S-adenosyl-L-methionine on paracetamol hepatotoxicity in a mouse model.

This study investigated the hepatoprotective effects of N-acetylcysteine and different doses of S-adenosyl-L-methionine after a single intraperitoneal overdose of paracetamol in mice. Plasma concentrations of paracetamol metabolites were also determined. Female mice (Souris OFl strain) 16 weeks old and weighing 30 g were fasted for 18 h prior to intraperitoneal (i.p.) administration of 375 mg/kg (2.5 mmol/kg) of paracetamol. Experimental subgroups included mice administered paracetamol only (control group), those given of N-acetylcysteine 1 g/kg (6.13 mmol/kg) i.p. immediately after paracetamol overdose (T0) and 6 h after dosing (T6) and those administered S-adenosyl-L-methionine at doses of 20 mg/kg (0.05 mmol/kg) and 1 g/kg (2.5 mmol/kg) i.p. at T0 and T6. Twenty-four hours after paracetamol overdose, mortality and liver necrosis were significantly lower (p < 0.01) in mice treated with 2.5 mmol/kg of S-adenosyl-L-methionine and N-acetylcysteine at T0 as compared with the remaining subgroups. Plasma ALT concentrations were significantly lower (p < 0.01) in mice treated with 2.5 mmol/kg of S-adenosyl-L-methionine than in those given N-acetylcysteine. Plasma concentrations of paracetamol metabolites showed an increase in the glucuronide conjugate and a decrease in the mercapturic acid conjugate in N-acetylcysteine-treated mice and an overall decrease in the conjugation pathway without changes in the oxidative pathway in S-adenosyl-L-methionine-treated animals. We conclude that S-adenosyl-L-methionine at doses of 1 g/kg (2.5 mmol/kg) i.p. was equally effective as 1 g/kg (6.13 mmol/kg) N-acetylcysteine for preventing hepatotoxicity after paracetamol overdose in mice. S-adenosyl-L-methionine may be a therapeutic alternative to N-acetylcysteine as an antidote for poisoning with paracetamol.

[Tracheobronchial amyloidosis. A rare form of amyloidosis restricted to the lower respiratory tract]. / Amiloidosis traqueobronquial. Una forma infrecuente de amiloidosis restringida al tracto respiratorio inferior.

We describe an 83-year-old man with diffuse tracheobronchial amyloidosis presenting with pneumonia, against a background of chronic obstructive pulmonary disease. The condition continued with intermittent episodes of obstruction for 2 years after diagnosis and the patient died after upper digestive tract hemorrhage. Monoclonally was never demonstrated.

Pulmonary dirofilariasis mimicking lung cancer.

We describe the case of a 30-year-old asymptomatic farmer who underwent a pulmonary segmentectomy due to the casual finding of a pulmonary nodule in preoperative chest radiography. As bronchoscopic samples rule out mycobacterium infection and malignancy, surgery could have been avoided with the use of serological tests and radiographic follow-up based on epidemiology of dirofilariasis in our country.

[Plasma levels of alanine aminotransferase in experimental liver necrosis induced by overdosage of paracetamol in mice]. / Niveles plasmáticos de ALT tras necrosis hepática experimental inducida por sobredosis de paracetamol en el ratón.

OBJECTIVE: To investigate the correlation between the hepatocellular damage and ALT plasma level after paracetamol overdosage in mice. EXPERIMENTAL DESIGN: A total of 30 female, 16 week-old mice (Souris OF1 strain), weighing 25-30 g were used. After 18 hours fast period, single doses of 500 mg/kg of paracetamol were administered intraperitoneally. The animals were killed by decapitation 24 hours after paracetamol injection, fasting being continued, although free access to water was allowed. ALT plasma levels were determined. The hepatocellular damage was graded from 0-4 (+). Plasma levels of mercapturate conjugate were measured by HPLC. RESULTS: The study showed a statistically significant correlation (r = 0.8, p = 0.00001) between ALT plasma levels and the degree of hepatocellular damage but not with concentrations of mercapturate conjugate. CONCLUSIONS: These findings suggest that ALT plasma levels give a reliable indication of the severity of hepatic necrosis, after experimental paracetamol overdosage in mice.

[Recurrent rectorrhagia caused by angiodysplasia of the colon localized exclusively by scintigraphy with Tc-99m red blood cells]. / Rectorragia recidivante por angiodisplasia de colon, localizada exclusivamente mediante gammagrafía con 99mTc-hematíes.

A case of angiodysplasia of the colon with clinical manifestation of massive rectal bleeding is presented. The activity and the severity of the life-threatening bleeding episode led to emergency exploratory laparotomy with intraoperative colonoscopy which was not diagnostic. Three years later, following multiple recurrent bleeding episodes and non diagnostic explorations, the localization of the hemorrhage was obtained by abdominal scintigraphy with 99mTc-red blood cells. Surgical removal of the affected area achieved definitive cure.

[Pancreatic insufficiency: an infrequent manifestation of primary hyperparathyroidism]. / Insuficiencia pancreática: una manifestación infrecuente del hiperparatiroidismo primario.

A case of malabsorption of pancreatic etiology secondary to primary hyperparathyroidism (HPT) is reported. Normalization of calcemia was achieved with parathyroidectomy and oral administration of pancreatic enzymes was initiated. HPT is an infrequent cause of pancreatic inflammatory disease. Although its association is controversial, its inclusion among the causes of exocrine pancreatic failure allows correct diagnosis and therapeutic management with a favorable prognosis.

[Renal and urinary tract leishmaniasis. A disease to keep in mind]. / Leishmaniasis renal y vías urinarias. Patología a tener en cuenta.

Report of a case of renal and urinary tract leishmaniasis in a 61-year old male patient. The ureteral lesion responded favourably to treatment, unlike the renal one which required conservative surgery. Review of the literature stressing the fact that no other case has been found of kidney and urinary tract involvement. It is concluded that in the future, at least in those areas with a high prevalence of leishmaniasis, this condition should be taken into account as differential diagnosis when facing a toxic picture with renal involvement of the calyceal ecstasies type.

Protective effect of diltiazem against acetaminophen hepatotoxicity in mice.

There is evidence that an increase in cytosolic Ca++ concentration is a terminal event in the progression to cell death in toxic liver injury. We have compared the hepatoprotective effects of N-acetylcysteine (1 g/kg) and the calcium channel blocking agent, diltiazem (24 mg/kg), when given at 30 min, 3 h and 6 h after single intraperitoneal overdoses of acetaminophen (500 mg/kg) in mice. Overall beneficial effects on mortality, liver necrosis score, and plasma alanine aminotransferase (ALT) activity were found in diltiazem-treated mice 24 h after acetaminophen overdose. However, the most marked effects were obtained when diltiazem was given 6 h after acetaminophen. N-acetylcysteine was more effective than diltiazem at 30 min and 3 h, although it was less effective at 6 h. Mean plasma concentrations of the mercapturate metabolite (hepatic oxidative metabolism) were not significantly different among animals receiving acetaminophen alone or in combination with diltiazem, which suggests that the hepatoprotective effects of diltiazem are not exerted by inhibition of drug metabolic enzymes.

Hyperimmunoglobulinemia E syndrome of neonatal onset.

A case of hyperimmunoglobulinemia IgE with recurrent infections of neonatal onset and unfavourable evolution is described. The first clinical finding was the appearance of maculopapular rash in the skin when the child was fifteen days old. From this period onwards, respiratory and cutaneous infections were continuous, leading to a progressive deterioration of the general condition, and malnutrition, which ended fatally at the age of three years. IgE levels were measured on several occasions, this being 17 IU/ml at the onset of the symptoms; afterwards, the mean value was 17.680 IU/ml (Range: 14.9-32.710 IU/ml).

Intracranial and mediastinal inflammatory myofibroblastic tumour.

Inflammatory myofibroblastic tumour (IMT) is a rare neoplastic condition, commonly known as inflammatory pseudotumour, which is the most frequent primary tumour of the lung in childhood. IMT can have an extrapulmonary location, but is infrequent in the brain and mediastinum, and it is extremely unusual that both lesions appear simultaneously as in our patient. The definitive diagnosis is established by biopsy, but there are some MRI findings that can be useful to identify the lesion.

[Adenomatoid tumor of the testicular vaginal tunic: apropos of a case]. / Tumor adenomatoide de Túnica vaginal testicular: a propósito de un caso.

The authors present a case of adenomatoid tumour of the vaginal testicle tunica, found by chance during a post-mortem study in a 70-year old male. After reviewing the literature they reveal its infrequency. According to the latest, histochemical and ultrastructural investigations carried out by several authors, its origin is mesothelial and therefore it may be called a benign mesothelioma.

[Visceral leishmaniasis located in the intestines in patients with human immunodeficiency virus infection: a report of 2 cases]. / Leishmaniasis visceral de localización intestinal en pacientes con infección por el virus de la inmunodeficiencia humana: presentación de dos casos.

We discuss two cases of visceral leishmaniasis (VL) with intestinal invasion in patients diagnosed of infection due to human immunodeficiency virus (HIV). The onset was as diarrheic manifestation associated to a constitutional syndrome, with no fever. One of the patients responded to treatment with antimonials, while the other died. References on this subject are scarce, being found on a literature search two similar cases as the ones described by us. We think that with every diarrheic process in HIV+ patients, VL diagnosis should be considered, and an intestinal biopsy should be performed.

Cutaneous hyalohyphomycosis caused by Paecilomyces lilacinus in an immunocompetent host successfully treated with itraconazole: case report and review.

Paecilomyces lilacinus is an emerging fungal pathogen that is highly resistant to many antifungal drugs. Skin and subcutaneous soft tissue infections caused by this organism are very unusual. Most cases occur in patients with impaired host defenses or following surgical procedures. There has been only one previous report of a histologically confirmed cutaneous infection due to Paecilomyces lilacinus in a patient without predisposing factors. Described here is the second histopathologically proven case of Paecilomyces lilacinus cutaneous infection in a healthy patient without any apparent portal of entry. Prolonged antifungal chemotherapy with itraconazole led to resolution of the skin lesion. This case of sporadic cutaneous infection due to Paecilomyces lilacinus is believed to be the first reported in Europe and the first histopathologically proven case successfully treated with itraconazole.

Changes in P-glycoprotein expression in gastric carcinoma with respect to distant gastric mucosa may be influenced by p53.

BACKGROUND: The effectiveness of some chemotherapeutic agents used to treat gastric carcinoma patients may be impaired by the presence of P-glycoprotein (P-gp) and the status of p53. A modulation of P-gp expression by p53 or other alterations during tumorigenesis have been reported. The authors analyzed P-gp expression in relation to p53 and histopathologic features in gastric carcinoma. METHODS: Forty-one resected gastric carcinomas and mucosa distant from the tumor were assessed for P-gp expression by immunohistochemistry with C494 and JSB-1 antibodies. p53 expression was also immunohistochemically assessed by DO7 antibody in tumor samples. P-gp and p53 expression were semiquantitatively analyzed according to the percentage of stained cells. Histologic type, grade, vessel invasion, and stage were also studied. RESULTS: Moderate or high P-gp expression was detected in gastric carcinoma in 29 cases (71%) and in gastric mucosa remote from the tumor in 36 cases (88%). This reduction in P-gp expression was observed in 22% of the carcinomas, all but 1 being p53 immunonegative tumors. Thus, 8 (42%) of the p53 immunonegative carcinomas showed a loss of P-gp expression compared with their distant gastric mucosa. All p53 immunopositive carcinomas coexpressed P-gp. No correlation between P-gp expression and histologic type, grade, vessel invasion, or stage was found. CONCLUSIONS: P-gp expression in gastric carcinomas is frequent and coexpression with p53 is found. The analysis of P-gp expression in carcinomas and distant mucosa show that it is not regulated by p53, but a loss of P-gp detected in some of these carcinomas is mainly associated with a lack of p53 protein accumulation.

Detection of P-glycoprotein in frozen and paraffin-embedded gastric adenocarcinoma tissues using a panel of monoclonal antibodies.

AIMS: Most chemotherapeutic regimens used against gastric carcinoma include anthracyclines whose effectiveness can be impaired by the presence of P-glycoprotein. In order to obtain a reliable pattern of P-glycoprotein expression in these tumours an immunohistochemical study using a panel of anti-P-glycoprotein antibodies was performed in frozen and paraffinized tissues. METHODS AND RESULTS: Frozen and paraffinized samples from 25 gastric carcinomas were immunohistochemically analysed using a panel of four anti-P-glycoprotein monoclonal antibodies including C219, MRK16, JSB-1 and C494. Semiquantitative analysis indicated that moderate or high P-glycoprotein levels were detected in 40% to 76% of gastric adenocarcinomas, depending on the anti-P-glycoprotein antibody used. The antibody C494 was the most sensitive in detecting P-glycoprotein in both frozen and paraffinized gastric carcinoma samples. Moreover, C494 showed a pattern of staining exclusively associated with the plasma membrane, in contrast to the cytoplasmic with reinforcement of plasma membrane pattern displayed by the other three antibodies. Significant differences in P-glycoprotein levels were obtained when C494 and MRK16 were used in frozen tissues. Finally, detection of P-glycoprotein in frozen samples did not improve when compared to paraffinized ones. CONCLUSIONS: It appears that P-glycoprotein is frequently expressed in gastric adenocarcinomas, and the use of C494 complemented by JSB-1 is recommended for reliable detection of P-glycoprotein in this neoplasm.
