RESUMO

BACKGROUND: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new intraabdominal technique to approach non-resectable peritoneal carcinomatosis (PC). PIPAC can be performed alone or alternated with systemic chemotherapy to increase tumor regression. We describe our initial experience performed in an expert hyperthermic intraperitoneal chemotherapy (HIPEC) French center to demonstrate the safety and the feasibility of PIPAC. METHODS: Between January 2016 and March 2019, PIPAC was proposed to 43 consecutive patients affected by digestive, ovarian, peritoneal and mammary carcinomatosis. Initially PIPAC was proposed to patients non eligible for cytoreductive surgery for palliative purposes. In five patients we associated PIPAC to systemic chemotherapy to improve tumor regression and enhance the chance of patients to undergo HIPEC. Three PIPAC treatments were supposed to be performed for each patient with an interval of 6 weeks in between each procedure. Peritoneal biopsies were always performed to evaluate microscopic tumor regression. In case of postoperative clinical deterioration or quick tumor progression during the cycles, PIPAC was interrupted. Depending on the primary tumor, chemotherapies used were oxaliplatin or a combination of cisplatin and doxorubicin. RESULTS: Twenty-six (60.4%) patients have already had a surgical resection or intervention of primary cancer removal. In 5 patients abdominal access was impossible. Of the 38 patients operated, seventy-one procedures were performed. In the series, one patient died because of tumor progression. Only one major complication occurred intraoperatively. Two of thirteen patients receiving oxaliplatin had postoperative abdominal pain and needed more drugs assumption and a longer hospitalization. Three patients after a three cycles procedure underwent HIPEC. Nine of the patients who had at least two PIPACs had last biopsies showing a major or complete tumor response. CONCLUSION: PIPAC is a safe and feasible procedure that can be performed in patients with peritoneal carcinomatosis initially not eligible for surgery to reduce tumor invasion or for palliation to reduce symptoms. Contraindications are bowel obstruction and multiple intraabdominal adhesions.

RESUMO

PURPOSE: Few studies have described the epidemiology of human papillomavirus (HPV) in vulvar intraepithelial neoplasia (VIN). The aim of this study was to genotype HPV on formalin fixed paraffin-embedded tissues in VIN lesions. METHODS: A 5-year retrospective study was conducted by including all patients attending the teaching hospital of Nice with a diagnosis of VIN between 1st January 2010 and 31st December 2014. For all patients, HPV genotyping was performed with the PapilloCheck® microarray kit, routinely used on cervical cytology samples, and optimized for formaldehyde fixed paraffin-embedded tissues in VIN. RESULTS: Forty patients were included in the study: 39 patients had usual VIN and one presented with differentiated VIN. Among the 39 patients with usual VIN, the prevalence of HPV was 90% (35/39). Thirty-two patients had high grade VIN (82%) and seven low grade VIN (18%). In high grade VIN, the most represented HPV types were: HPV 16 (21/32 66%), HPV 56 (3/32 9%) and HPV 33 (2/32 6%). In low grade VIN, the most represented HPV types were: HPV 16 (4/7 57%) and HPV 6 (3/7 43%). Interestingly, 5/39 (13%) of patients diagnosed with usual VIN also had co-existing lichen sclerosus. CONCLUSIONS: We have optimized a HPV genotyping technique, routinely used on cervical cytology samples, and on paraffin fixed embedded tissue showing VIN. Moreover, we have identified five patients with lichen sclerosus co-existing with usual VIN. This association has rarely been reported and proves that these two entities can coexist.

RESUMO

BACKGROUND: Primary lymphedemas are constitutional abnormalities of the lymphatic system. Secondary lymphedemas occur after damage to the lymphatic system, mainly after cancer treatments or tumour mass compression. There are many other causes, including filariasis, which is nonetheless very rare in France. PATIENTS AND METHODS: A 52-year-old man presented with a two-month history of increased size of the left leg. He was asymptomatic and in good general condition. Clinical examination revealed non-pitting lymphedema and ipsilateral hydrocele without loco-regional compressive lymph node. Initial extensive explorations were unremarkable. Lymphoscintigraphy revealed low tracer fixation in the left leg. The symptoms continued to worsen, with exacerbation and bilateralization of the lymphedema. Two months later, axillary lymph nodes appeared corresponding to metastasis from a signet-ring cell carcinoma. Despite two lines of chemotherapy, the patient died 8 months later due to multiple metastatic disease. DISCUSSION: Our case is remarkable because the lymphedema was not related to extrinsic compression and was the first symptom of gastric cancer. In the absence of compression, endo-lymphatic micro-metastases could constitute the causative process. Acquired lymphedema of the lower limbs must be recognized as a potential early symptom of gastric carcinoma and should therefore prompt further investigations.

RESUMO

OBJECTIVES: The recommended daily dose of acetaminophen is limited to 60mg/kg/day with a maximum of 3g daily dose in adults weighing less than 50kg or in patients undergoing certain risk factors. This study aimed at assessing the fulfillment of those recommendations and the possible impact on the liver dysfunction at supra-therapeutic doses of acetaminophen. METHODS: This study was performed one day in 9 services. Patients characteristics, acetaminophen dose, daily dose administered, physiopathological aspects, markers of liver damage were collected. RESULTS: Among 542 prescriptions analyzed, 343 of them contained acetaminophen. The median age of patients studied was 81 years and one third weighed less than 50kg. The main risk factor of supra-therapeutic prescriptions was the lack of dose acetaminophen based on weight with 14% patients concerned and this risk raised at 17% when the pathophysiological conditions were included. The presence of pharmacists in medicals departments was more effective than the use of informatics programs limiting the dose systematically to 3g/day, or a distant pharmaceutical validation from care services to reduce the risk of acetaminophen overdose. According to the statement of administrations, only 4 of 49 patients received doses above 60mg/kg/day with a low impact on liver function tests. CONCLUSION: The continuous presence in pharmaceutical care services was the most effective measure to ensure effective implementation of acetaminophen recommendations.

RESUMO

Bronchogenic cyst of the tongue is rare. We report the case of a 17-month baby who has a lingual lesion. MRI shows a well-defined cystic lesion. Treatment consisted of a complete resection and histology found a pseudostratified respiratory type epithelium. Only 10 pediatric cases of bronchogenic cyst of the tongue have been reported in the literature. MRI is the imaging modality of choice and treatment is always surgical. The final diagnosis is made by histology.

RESUMO

Melanotic Neuroectodermal Tumor of Infancy (MNTI) is a rare but distinct neoplastic entity in infancy. Diagnosis is usually made before the age of 12 months. The common clinical presentation is a rapidly growing mass of the pre-maxillary area. Its surface is unevenly pigmented. To affirm the diagnosis a biopsy is necessary. Few cases of malignancy have been described (5% of cases). Adequate surgical excision is the treatment of choice. Recurrence rate is about 10 to 15% within 5 years. We report in this article the case of a newborn with MNTI illustrating that an R0 surgical excision can be correlated to a favourable prognosis. In this case the 5 years follow up didn't show any local or distant recurrence.

RESUMO

OBJECTIVES: To assess the documentation of the 72-hour antibiotic therapy reassessment in medical records. METHODS: One-day prevalence evaluation of curative antibiotic therapies≥72hours. The documentation of the reassessment was defined according to three criteria: (1) "clear" documentation (clinical or microbiological comment associated with a comment on the need to adjust the antibiotic therapy or on the lack of need); (2) "tacit" documentation (only based on a clinical or microbiological comment); (3) no documentation. RESULTS: We assessed 114 antibiotic therapies in 26 hospital departments. A clear reassessment at 72hours was observed in only 45 (39%) records and 31 (27%) records had no reassessment. The planned duration of treatment was written in 63 (55%) records. At 72hours, among the 71 antibiotic therapies with a microbiological documentation, 69 (97%) were active and 44 (62%) had a narrow spectrum. Among the 48 antibiotic therapies with a broad spectrum on day 1, only 21 (44%) benefited from a de-escalation at 72hours. A clearly recorded reassessment at 72hours was associated with de-escalation (P=0.025) and the prescription of a planned duration of treatment was associated with antibiotic therapy compliance with local or national guidelines (P=0.018). CONCLUSION: Although reassessment was observed in 73% of records, it was correctly recorded at 72hours in only 39% of cases. The documentation of the reassessment and the prescription of a planned duration were associated with a better quality of antibiotic prescription (de-escalation, compliance with guidelines) and are relevant indicators for monitoring the proper use of antibiotics.

RESUMO

Adrenal gland involvement could account for 6% of active tuberculosis. The diagnosis of this extrapulmonary form of tuberculosis is difficult, especially when presenting as unilateral adrenal tumor. This report describes an unusual case of adrenal tuberculosis presenting as a tumor occurring shortly after surgical removal of an adrenal pheochromocytoma located in the opposite gland, in a 63-year-old woman with a previous history of breast cancer. At initial presentation, the patient suffered from symptomatic paroxysmal hypertension. A pheochromocytoma in the left adrenal was diagnosed and resected. One year later, while physical examination and biological parameters were unremarkable, an enhanced adrenal computed tomography (CT) scan showed a right adrenal mass mimicking the CT features of the resected pheochromocytoma. A peripheral tissular rim delineating a central hypodensity characterized this tumor. Magnetic resonance imaging (MRI) showed the same findings on gadolinium-enhanced T1-weighted slices, while the mass was not seen on T2-weighted images. No tumoral signal loss was observed on out of phase images when using the in phase-out of phase T1-weighted sequence. Because of the tumoral evolution and the uncertainty of the nature of that lesion, the patient underwent a second adrenalectomy. Definitive diagnosis was provided by culture of tissue sample, which resulted in the identification of Mycobacterium tuberculosis. In an era of tuberculosis resurgence, this unusual case underscores the necessity of keeping in mind adrenal tuberculosis as a possible differential diagnosis in adrenal tumors of uncertainty nature. It stresses the importance of culture of biopsy tumor, whenever feasible, to avoid unnecessary operations. In the near future, interferon-gamma assay could be a valuable means to recognize extrapulmonary forms of tuberculosis.

RESUMO

The objective of this study was to identify factors affecting variation in conception rate to first artificial inseminations (AI) (CR: number of pregnant cows on D80-100/inseminated cows) and the incidence of embryonic/foetal loss (LEM) between 21 and 80 days of pregnancy (number of cows non-pregnant on D80-100/pregnant on D21) in 44 low fertility dairy herds of the west-central region of France. Reproductive status was assessed using progesterone milk concentration on D0 = Day of AI and D21-24, plasma PSPB concentration on D30-35, rectal palpation on D80-100 and observed return to oestrous. The final data set contained 1285 Prim'Holstein cows, 5.0% (64/1285) were inseminated in the luteal phase (progesterone > or = 3 ng/ml on D0), 61.3% (787/1285) were pregnant on D21-24 (progesterone < 3 ng/ml on D0 and > or = 5 ng/ml on D21-24), 15.4% lost their embryo/foetus between D21-24 and D80-100 (198/1285) and 45.8% (589/1285) were pregnant on D80-100. The incidence of late embryonic/foetal loss (LEM) was 25.2% (198/787). Multivariate logistic regression models including the random herd effect were used to analyse the relationship between AI centre, AI sire, cow's sire, parity, interval between calving and AI, milk production, milk protein content, body condition score (BCS) on D0, season of calving, season of AI, estimated genetic index on CR and LEM incidence. CR was significantly related to parity (p < 0.05), milk production after calving (p < 0.05) and estimated genetic value (p < 0.01). A significant difference in CR was observed for calving to AI interval > or = 70 days versus > or = 90 days, but the overall effect of the interval was not significant (p = 0.11). LEM incidence was affected by period of AI (p < 0.05), milk production (p < 0.05) and BCS (p < 0.05), but was not related to estimated genetic index. In conclusion, in these low fertility herds, the incidence of LEM was high and 25% of the cows lost their embryo after 21 days of pregnancy. LEM was affected by specific factors (season, BCS), which were not related to CR. The absence of a relationship between estimated genetic index and LEM in spite of its effect on CR indicates that estimated genetic merit has a greater effect on early embryonic loss or fertilisation failure than on later stages of embryo development.

RESUMO

Elderly patients are at high risk of over-anticoagulation and of haemorrhagic risk when on warfarin, especially during treatment induction. In Charles Foix Hospital, a 800-bed geriatric hospital, we specifically developed for in-patients older than 70 years (target INR 2.5) a simple low-dose warfarin induction regimen. The dosing recommendations were summarized on a prescribing guidance pocket chart. Eighteen months after the distribution of the chart, we conducted a one-year observational study in order to evaluate: i/ the time needed to achieve the warfarin maintenance dose; ii/ the prescriber'adherence to the recommendations; iii/ the benefit for elderly patients receiving warfarin therapy. The mean time needed to achieve the warfarin maintenance dose was 12.3 +/- 7.0 days for the 89 patients included in the study: 10.6 +/- 5.9 days for the 30 patients whose prescribers followed the recommendations versus 13.5 +/- 7.6 days for the 59 patients whose prescribers did not follow the recommendations. There is a trend to a more frequent over-anticoagulation in patients whose prescribers did not follow the recommendations. The duration of the heparin-warfarin overlap was significantly shorter when the recommendations were followed. Finally, the reasons for non-adherence to the recommendations were analyzed. This study illustrates an assessment of practice in an health care institution.

RESUMO

Myoclonus--dystonia is a genetically heterogeneous autosomal dominant disorder caused by a mutation in the D2 dopamine receptor on chromosome 11 and a locus on chromosome 7q21-q31. The authors tested linkage to the chromosome 7q candidate region in four families with either myoclonic dystonia (n = 3) or essential myoclonus (n = 1). Age at onset ranged from 0.5 to 38 years. Only four patients from two families had a positive response to alcohol. Lod scores were positive in all four families, suggesting that chromosome 7q21-q31 is a major locus for myoclonus-dystonia with several phenotypes.

RESUMO

Eighteen out of twenty amino acids have been used for identifying tRNAs from the silkworm Bombyx mori L. fractionated on two-dimensional polyacrylamide gel electrophoresis. 43 spots out of 53 have been identified. This mapping confirms previous results and brings new answers to some questions on the regulation of tRNA biosynthesis. 1. In addition to quantitative adaptation of tRNAs to the composition of silk proteins (fibroin from the posterior silk gland, sericin from the middle part) and of iso-tRNAs from posterior silk gland to the major codons of fibroin mRNA, we also observe adaptation of tRNA from various tissues to the average amino acid content of proteins from fat body, gut, gonads and carcass of the silkworm. 2. In the silk gland, turnover rates of several tRNA species are similar. The selective accumulation of tRNAs needed for decoding fibroin and sericin mRNAs which takes place during the Vth larval instar, cannot be explained by the occurrence of a preferential degradation of some tRNA species. 3. Under given conditions for incubating silk glands, it is possible to obtain an accumulation of precursor tRNA species, which are enriched in pre-tRNAAla and pre-tRNAGly in the posterior silk gland and pre-tRNASer in the middle part. 4. The distribution of tRNA genes is not random. tRNA genes for glycine, alanine and serine are prominent. Selective transcription of batteries of iso-tRNA genes could explain our data.

RESUMO

The Coffin-Lowry syndrome (McKusick No. 30360) is a rare genetically transmitted disorder characterized by severe mental retardation, "coarse" facial appearance, thick soft skin, tapering fingers, and progressive skeletal abnormalities. X-linked inheritance is implied since the males are severely affected with variably mild manifestations in carrier women. We have performed a linkage analysis with many X-linked RFLP markers in 4 families. Positive two-point lod scores were obtained with DXS28 (z(theta) = 2.00 at theta = 0.05) and DXS41 (z(theta) = 1.26 at theta = 0.10). We performed a 5-point linkage analysis using the LINKMAP program assuming that DXS16 and DXS43 are a single locus and using the following fixed map (distances in centimorgans): DXS85 - 18cM - (DXS16, DXS43) - 13cM - DXS41 - 5cM -DXS28. This gave a multipoint lod score of 3.41 for a localisation in Xp22.2-p22.1, between DXS43 and DXS41.

RESUMO

Mazabraud syndrome is a rare sporadic disorder, mainly characterized by bone fibrous dysplasia and intramuscular myxomas. We report here two new cases of Mazabraud syndrome. One of our patients (Patient 1) also had café-au-lait spots and multinodular goiter suggestive of McCune-Albright syndrome. We review the 37 previously reported cases with Mazabraud syndrome and discuss the 6/37 patients with criteria of Mazabraud and McCune-Albright syndromes. Based on the clinical overlap between the two syndromes, we tested the GNAS1 gene in blood leukocytes and skin fibroblasts of Patient 1, but found no evidence of an activating mutation in the GNAS1 gene.

RESUMO

In order to develop a biodegradable interlocking nail for fracture fixation, hydoxylapatite pins and paste were implanted in the femoral bone of rats. A distal fracture was performed. The union and the tissue reaction to hydroxylapatite versus stainless-steel rods were studied after 15 days, 1, 2 and 6 months implantation. Metal pins induced a union. Hydroxylapatite pins (Ossatite) did not prevent callus formation, but did not lead to consolidation in all cases due to weakness of gelatin matrix binding the apatite particles together. The biocompatibility of material is satisfactory and the osteo-inductive properties of hydroxylapatite was confirmed. With injectable Ossatite , we could not obtain rat femoral fracture consolidation. We can confirm good biomaterial tolerance in bone which contrasts with important soft tissue reactions. Use of such material should be carefully limited to filling intra-osseous cavities.

RESUMO

A 37-year-old woman underwent resection of an abdominal tumour which was adherent to the wall of the ileum. The diagnosis of an ependymoma was supported by evidence of typical perivascular pseudorosettes which stained positive for glial fibrillary acidic protein and contained abundant intermediate filaments within the elongated processes by electron microscopy. Flow cytometric study showed a diploid population of tumour cells. This is the first case of an ependymoma arising from the small bowel without any connection to the genital tract, the omentum or with the sacroccygeal area. As is the case with other unusual and ectopic localisations of ependymomas, prognosis of this tumour is difficult to evaluate.

RESUMO

We report the case of an infant aged of 14 months deceased of sudden death. The diagnosis of histiocytoid cardiomyopathy was made on a necropsic basis. The pathologic examination showed a cardiac hypertrophy characterized by yellowish areas with irregular outlines, disseminated in the myocardium, and made of histiocyte-like cells with foamy or granular cytoplasm. These cells reacted positively with desmin and myoglobin labels, and had rare and disorganised myofibrils in electron microscopy, proving their muscular origin. The illness affects infants and usually causes severe cardiac troubles leading to death without treatment. This case is the fourteenth associated with sudden death.

RESUMO

We report on a 12 year-old girl with severe myopia, ectopia lentis, dilatation of the ascending aorta, protrusio acetabulae, arachnodactyly, scoliosis and moderate short stature (-1.7 SD). Her sister and father presented with Marfan's syndrome. Despite short stature, Marfan's syndrome could not be ruled out. Primary amenorrhoea and growth retardation indicated cytogenetic analysis which showed chromosomal aberration 45,X in every studied cell. However, she did not present any other clinical features of Turner's syndrome. We report here for the first time on an association of Turner's syndrome and Marfan's syndrome in the same patient, and discuss particular clinical features.

RESUMO

The authors report the sonographic, computed tomography (CT), and magnetic resonance imaging (MRI) findings in a patient with acquired porphyria cutanea tarda and hepatic multi-nodular focal fatty metamorphosis. There has only been one previous description of an association between these two conditions. The diagnosis was confirmed by histological analysis of a liver biopsy specimen. Symptomatology related to the hepatic abnormality may be due to an inflammatory reaction induced by the presence of uroporphyrin crystals in the liver. Each of the radiological techniques demonstrated unusual hepatic abnormalities and, in particular, MRI showed poorly defined areas in the liver which, on T2-weighted sequences, exhibited a hypersignal with fat saturation. Treatment of porphyria cutanea tarda led to clinical remission and resolution of radiological abnormalities.
