Refractory Chylothorax Secondary to Sizeable Azygos Vein Hemangioma: Tailored Multimodal Treatment of a Challenging Case Report.

BACKGROUND: Mediastinal hemangiomas are rare, and their etiology remains unclear. Most patients affected have no pathognomonic clinical symptoms, and the diagnosis is often incidental. Due to the paucity of the available literature regarding the management of this disease, the choice and timing of treatment remains controversial. CASE PRESENTATION: Herein, we report the case of a hemangioma of the azygos vein arch in a 66-year-old woman who presented with dyspnea, chest discomfort, dysphagia, and weight loss. A simultaneous right chylothorax refractory to conservative management was found. A CT-guided biopsy of the mass was performed, and it confirmed the vascular nature of the lesion. Therefore, the patient underwent an angiography followed by endo-vascular embolization. Three days later, thoracoscopic surgical resection of the mass and the repair of the chyle leakage were performed safely. The patient was discharged uneventfully on postoperative day seven, with complete resolution of all the presenting symptoms. CONCLUSIONS: Treatment of symptomatic mediastinal hemangiomas could be mandatory, but a thorough multidisciplinary approach to these rare malformations is essential. Despite the risk of intraoperative bleeding, selective endovascular embolization followed by thoracoscopic surgery allowed for a complete and safe resection with a good outcome.

Feasibility and safety of total laparoscopic hysterectomy for uteri weighing from 1.5 kg to 11.000 kg.

PURPOSE: To assess the feasibility and safety of total laparoscopic hysterectomy (TLH) for uteri ≥ 1.5 kg. METHODS: We prospectively evaluated all elective TLHs (with or without adnexectomy) performed for fibromatous uteri between August 2009 and August 2019 in the Department of Obstetrics and Gynecology, Sirai Hospital, Carbonia, and the Department of Gynecologic Oncology, Businco Hospital, Azienda Ospedaliera Brotzu, Cagliari. Patients with large myomatous uteri (uterine weight ≥ 1.5 kg on pathology reports) were included in the analysis. We examined all procedures and collected data about intra- and post-operative short-term and long-term complications, intraoperative blood loss, operative time, hospital stay, and time to achieve well-being. RESULTS: Seventy-eight patients were included. The median weight was 2,000 g (range 1,500-11,000 g), estimated blood loss was 100 mL (range 10-700 mL), operating time was 135 min (range 60-300 min), and hospital stay was 2 days (range 2-5 days). Conversion to laparotomy occurred in 4 patients (5.1%) with uterine weight ranging from 3 to 5.5 kg, due to severe adherence syndrome or inadequate visualization. As for intraoperative complications, 1 patient (who had the largest removed uterus weighing 11,000 g) experienced an intraoperative ureteral injury (grade III). No major postoperative complications occurred. CONCLUSIONS: This study provides the largest case series of TLH for fibromatous uteri > 1.5 kg and includes some of the largest uteri reported to date in the literature (weighing 5,320, 5,720, and 11,000 g, respectively). The study reaffirms the feasibility and safety of a minimally invasive hysterectomy even in the case of abnormally large uteri.

Top-down HPLC-ESI-MS detection of S-glutathionylated and S-cysteinylated derivatives of cystatin B and its 1-53 and 54-98 fragments in whole saliva of human preterm newborns.

Analysis by a HPLC-ESI-MS top-down proteomic platform of specimens of human preterm newborn whole saliva evidenced high relative amounts of cystatin B and its S-glutathionylated,S-cysteinylated, and S-S 2-mer (on Cys(3)) derivatives, decreasing as a function of postconceptional age (PCA). The percentage of S-unmodified cystatin B was higher than the S-modified isoforms in the early PCA period, differently from adults where cystatin B was detectable only as S-modified derivatives. The percentage of S-modified derivatives increased as a function of PCA, reaching at the normal term of delivery values similar to those determined in at-term newborns, babies, and adults. Moreover, in the early PCA period, high relative amounts of the 1-53 and 54-98 cystatin B fragments were detected, decreasing as a function of PCA and disappearing at the normal term of delivery. In agreement with intact cystatin B, fragment 1-53 was detectable as S-unmodified and S-modified derivatives, and their percentages changed accordingly with the percentages of intact proteins, suggesting that the fragmentation process could be subsequent to and independent from the S-modification of the protein. This study highlights specific enzymatic activity in the oral cavity of preterm newborns not present in at-term newborns and adults, which can be a clue to specialized pathways occurring during fetal oral development.

The surprising composition of the salivary proteome of preterm human newborn.

Saliva is a body fluid of a unique composition devoted to protect the mouth cavity and the digestive tract. Our high performance liquid chromatography (HPLC)-electrospray ionization-MS analysis of the acidic soluble fraction of saliva from preterm human newborn surprisingly revealed more than 40 protein masses often undetected in adult saliva. We were able to identify the following proteins: stefin A and stefin B, S100A7 (two isoforms), S100A8, S100A9 (four isoforms), S100A11, S100A12, small proline-rich protein 3 (two isoforms), lysozyme C, thymosins ß(4) and ß(10), antileukoproteinase, histone H1c, and α and γ globins. The average mass value reported in international data banks was often incongruent with our experimental results mostly because of post-translational modifications of the proteins, e.g. acetylation of the N-terminal residue. A quantitative label-free MS analysis showed protein levels altered in relation to the postconceptional age and suggested coordinate and hierarchical functions for these proteins during development. In summary, this study shows for the first time that analysis of these proteins in saliva of preterm newborns might represent a noninvasive way to obtain precious information of the molecular mechanisms of development of human fetal oral structures.

Environmental Influence on the Occurrence of Multi-Organ Cystic Echinococcosis Infection in a Patient from Sardinia, Italy.

An uncommon clinical case of an adult woman who was referred to the hospital with severe symptoms attributable to cystic echinococcosis (CE) is described in this report. According to a questionnaire, the subject was exposed to a high risk of infection since she was employed on a farm about 20 years before diagnosis. She lived close to several animal species and handled vegetables in inadequate hygienic conditions. Medical and laboratory investigations confirmed the presence of massive echinococcal cystic lesions in each lung and in the liver. Given the peculiarity of the case, pharmacological and surgical treatments were the only conceivable option. The association of pharmacological treatment, surgery, and interventional radiology procedure represented a reliable and effective way to handle a complex case of human hydatidosis. A multi-disciplinary approach was mandatory, resulting in a clear and conclusive diagnosis of CE caused by the zoonotic parasite E. granulosus sensu stricto of the G1 genotype.

The human salivary proteome: a critical overview of the results obtained by different proteomic platforms.

The development of new separation techniques and different mass spectrometry instrumental devices, as well as the great availability of specific reactants, offers ample choice to scientists for carrying out high-throughput proteomic studies and being competitive in the field today. However, the different options available often do not provide comparable results, which can be linked to factors such as the strategy adopted, the nature of the sample and the instrumental availability. In this critical review, the results obtained so far in the study of human saliva by different proteomic approaches will be compared and discussed.

HPLC-ESI-MS and MS/MS structural characterization of multifucosylated N-glycoforms of the basic proline-rich protein IB-8a CON1+ in human saliva.

This study describes the characterization of the glycan moieties and the peptide backbone of six glycoforms of IB-8a CON1(+), a basic proline-rich protein present in human saliva. MS analyses on the intact glycoproteins before and after N-deglycosylation with PNGase F and high-resolution MS/MS sequencing by LTQ Orbitrap XL of peptides and glycopeptides from tryptic digests allowed the structural characterization of the glycan moieties and the polypeptide backbone, as well as to establish the glycosylation site at the asparagine residue at 98th position. Five of the glycoforms carry a biantennary N-linked glycan fucosylated in the innermost N-acetylglucosamine of the core and showing from zero to four additional fucoses in the antennal region. The sixth glycoform carries a monoantennary monofucosylated oligosaccharide. The glycoform cluster was detected on 28 of 71 adult saliva specimens. Level of fucosylation showed interindividual variability with the major relative abundance for the trifucosylated glycoform. Nonglycosylated IB-8a CON1(+) and the variant IB-8a CON1(-), lacking of the glycosylation site, have been also detected in human saliva.

Alterations of the salivary secretory peptidome profile in children affected by type 1 diabetes.

The acidic soluble fraction of whole saliva of type 1 diabetic children was analyzed by reversed phase (RP)(1)-HPLC-ESI-MS and compared with that of sex- and age-matched control subjects. Salivary acidic proline-rich phosphoproteins (aPRP), histatins, α-defensins, salivary cystatins, statherin, proline-rich peptide P-B (P-B), beta-thymosins, S100A8 and S100A9*(S100A9* corresponds to S100A9 vairant lacking the first four amino acids), as well some naturally occurring peptides derived from salivary acidic proline-rich phosphoproteins, histatins, statherin, and P-B peptide, were detected and quantified on the basis of the extracted ion current peak area. The level of phosphorylation of salivary acidic proline-rich phosphoproteins, histatin-1 (Hst-1), statherin and S100A9* and the percentage of truncated forms of salivary acidic proline-rich phosphoproteins was also determined in the two groups. The study revealed that statherin, proline-rich peptide P-B, P-C peptide, and histatins, were significantly less concentrated in saliva of diabetic subjects than in controls, while concentration of α-defensins 1, 2 and 4 and S100A9* was higher. The low concentration of P-C peptide was paralleled by high levels of some of its fragments. On the whole, the study highlighted the severe impairment of the repertoire of peptides involved in the safeguard of the oral cavity in children who have diabetes, as well as an higher concentration of the proinflammatory mediator S100A9* with respect to healthy children.

Diagnostic Framework of Pelvic Massive Necrosis with Peritonitis following Chemoradiation for Locally Advanced Cervical Cancer: When Is the Surgery Not Demandable? A Case Report and Literature Review.

Concurrent platinum-based chemoradiation (CCRT) is the established treatment for locally advanced cervical cancer and has an acceptable toxicity. Radiation-induced necrosis of the uterus and pelvic tissue is a rare and usually late potential complication. Limited data are available about its management. Here, we describe a case of a patient affected by a locally advanced cervical cancer (stage IVA) who received CCRT, obtaining a partial response with persistence of bladder and rectal infiltration. Unfortunately, after the first brachytherapy dose, the patient developed a worsening clinical picture with fever and altered laboratory data indicative of sepsis; the computed tomography revealed a massive necrosis of the uterus with pelvic abscess and peritonitis. We performed a laparoscopic emergency surgery with removal of the necrotic tissue, supracervical hysterectomy, bilateral-oophorectomy, and abscess drainage. Thereafter, once the severe inflammatory condition was resolved, the patient underwent pelvic exenteration with palliative/curative intent. The postoperative PET/CT was negative for residual disease. However, the patient needed further hospitalization for re-occurrence of peritonitis with multiple abscesses. A careful diagnosis is crucial in locally advanced cervical cancer patients who, after CCRT, present persistent pain and problematic findings at imaging and laboratory parameters. In these cases, radiation-induced necrosis of the pelvis should be suspected. This case helps to clarify the central role of surgery, especially when actinic necrosis leads to complications such as abscess, fistulae, and extensive tissue destruction that cannot be conservatively medically handled. Laparoscopy represents an ideal approach to realizing the correct diagnosis, as well as enabling the performance of important therapeutic surgical procedures.

Pathogenic and Prognostic Roles of Paraneoplastic Leukocytosis in Cervical Cancer: Can Genomic-Based Targeted Therapies Have a Role? A Literature Review and an Emblematic Case Report.

Tumor-associated leukocytosis has been associated with poor prognosis in cervical cancer. Leukemoid reaction (i.e., white blood cell count > 40,000/µL) is defined paraneoplastic (PLR) when it occurs in the presence of a cytokine-secreting tumor (CST) without neoplastic bone marrow infiltration. Cervical cancers displaying PLR represent a peculiar entity characterized by a rapidly progressive behavior typically associated with chemo-radioresistance. The present paper aims to review the literature about the pathogenetic mechanisms of PLR and its prognostic role in cervical cancer. Moreover, it reports the emblematic case of a patient with an advanced cervical cancer associated with PLR that was chemotherapy resistant. The patient underwent a palliative cytoreductive surgery of high complexity, obtaining a temporary regression of PLR. The tumor sample stained positive for G-CSF and IL-6, thus indicating a CST. Notably, the tumor genomic analysis revealed a PI3CKA mutation. Therefore, at the instrumental evidence of a rapidly progressive disease relapse, which was accompanied by reappearance of PLR, we started a targeted treatment with a selective PIK3 inhibitor alpesilib combined with the JAK1-2 inhibitor ruxolitinib. We achieved a relief of symptoms and leukocytosis; however, severe side effects necessitated the treatment suspension. In conclusion, as therapeutic strategies for cancer with PLR are scarcely reported in literature, our study could contribute to expand our understanding of the topic and provide a basis for further research.

Next-Generation Sequencing Whole-Genome Analysis for Targeted Treatment Approach of Metastatic Bartholin Gland Adenocarcinoma: An Emblematic Case Report and Review of the Literature.

Bartholin gland adenocarcinoma (BGA) is extremely rare and is characterized by high rates of lymph-node recurrence and distant metastases. No effective palliative treatments are available for metastatic BGA; therefore, advanced BGA remains a challenge for gynecologic oncologists. Considering the rarity of this disease and the lack of a standardized approach, the present study aims to discuss the available literature on current therapies for BGA and to describe an emblematic case treated with a novel tailored approach. A postmenopausal woman with advanced BGA was referred to our department for an adequate evaluation, staging and treatment. Notably, we used PET/CT as a fundamental imaging technique for staging and follow-up. The patient underwent primary surgery followed by standard chemotherapy and pelvic radiotherapy. Three months later, she relapsed, with the appearance of multiple metastatic sites. Considering the evident chemoresistance to standard chemotherapy and the absence of valid therapeutic alternatives for this rare cancer, she was treated with a combination of repeated minimally invasive surgical procedures for all the resectable metastatic lesions and innovative approaches comprising, firstly, chemoimmunotherapy with Nivolumab combined with metronomic vinorelbine, which resulted in a clinical response for approximately 7 months. Upon disease progression, we used a targeted systemic approach based on the whole genomic profile of the primary tumor, which showed PTEN loss, which is predictive of a benefit from an mTOR inhibitor, and a CCND1 amplification, which predicts sensitivity to CDK4/6 inhibitors. Therefore, she received Everolimus, resulting in a significant metabolic response that lasted 12 months. Thereafter, upon further progression of the disease, the patient started Palbociclib treatment, which is currently ongoing, with evidence of a metabolic response. The patient has survived for 54 months from diagnosis, with a good performance status. In conclusion, the present paper confirms the lack of efficacy of conventional therapeutic regimens in the context of advanced, recurrent or metastatic adenocarcinomas of the Bartholin gland. The case report shows how a personalized multidisciplinary approach based on repeated minimally invasive surgery and tailored anticancer treatment based on whole-genome sequencing analysis could be effective and associated with prolonged survival in this rare gynecological cancer.

Characterization of two isoforms of human SPRR3 from saliva of preterm human newborn and autoptic fetal oral mucosa, parotid and submandibular gland samples.

RP-HPLC-ESI-MS profile of saliva samples from human preterm newborn showed a protein peak in the elution range 26.6-27.6min. Deconvolution of ESI-MS spectra revealed the presence of two proteins with average molecular mass (Mav) values of 17,239+/-3Da and 18,065+/-3Da in 9 samples, with Mav value of 17,239+/-3Da in 4 samples and Mav value of 18,065+/-3Da in 2 samples. MALDI-TOF-MS analysis of tryptic digest allowed identifying the proteins as two isoforms of small proline-rich protein 3 and cDNA amplification of RNA extracts from oral mucosa, parotid and submandibular gland samples, obtained at fetal autopsy, provided two nucleotide sequences in agreement with those reported in the literature. The two proteins differ for an octapeptide repeat (GCTKVPEP) and the substitution Leu-->Val, at position 148 and 140 of the mature form of the 18,065 and 17,239Da protein, respectively. During maturation the two proteins undergo two post-translational modifications, corresponding to N-terminal acetylation and removal of the initiator methionine. cDNA amplification did not allow to clarify if the proteins found in saliva originated from cellular shedding of the epithelium and/or secretion.

Laparoscopic management of a giant mucinous benign ovarian mass weighing 10150 grams: A case report.

BACKGROUND: Giant ovarian cysts (≥ 15 cm in diameter) are rare. The size limit of cysts and the methodology for a safe and successful minimally invasive surgery has not been established. Here we report a case of a large 10-kg multi-locular ovarian mass, which was successfully laparoscopically removed: Our aim was to innovate the surgical practice in this field by providing a safe, effective, and minimally invasive management method for such complex and rare cases. CASE SUMMARY: A 49-year-old nulliparous woman presented with abdominal distension, lasting from six Mo prior to admission; she reported worsening abdominal pain, abdominal swelling, and mild dyspnea. Imaging showed a presumed benign multi-locular (> 10 locules) left ovarian cyst that measured about 30 cm in diameter. Based on the IOTA-ADNEX model the mass had a 27.5% risk of being a borderline or malignant tumor. The patient was successfully treated via a direct laparoscopic approach with salpingo-oophorectomy, followed by the external drainage of the cyst. Tumor spillage was successfully avoided during this procedure. The final volume of the drained mucinous content was 8950 L; the cyst wall, extracted through the minilaparotomy, weighed about 1200 g. The pathologic gross examination revealed a 24 cm × 15 cm × 10 cm mass; the histologic examination diagnosed a mucinous cystoadenoma. To our knowledge, this is the first case of a giant multi-locular ovarian cyst treated with a direct laparoscopy with salpingo-oophorectomy followed by external decompression. CONCLUSION: Choosing the appropriate technique and surgeon skill are necessary for a safe and effective minimally-invasive approach of unique cases involving giant ovarian cysts.

Retrospective outcomes analysis of 99 consecutive uniportal awake lung biopsies: a real standard of care?

BACKGROUND: Surgical lung biopsy for interstitial lung disease (ILD) is traditionally performed through video-assisted thoracic surgery (VATS) and general anesthesia (GA). The mortality and morbidity rates associated with this procedure are not negligible, especially in patients with significant risk factors and respiratory impairment. Based on these considerations, our center evaluated a safe non-intubated VATS approach for lung biopsy performed in ILD subjects. METHODS: Ninety-nine patients affected by undetermined ILD were enrolled in a retrospective cohort study. In all instances, lung biopsies were performed using a non-intubated VATS technique, in spontaneously breathing patients, with or without intercostal nerve blockage. The primary end-point was the diagnostic yield, while surgical and global operating room times, post-operative length of stay (pLOS), numeric pain rating scale (NPRS) after surgery and early mortality were considered as secondary outcomes. RESULTS: All the procedures were carried out without conversion to GA. The pathological diagnosis was achieved in 97 patients with a diagnostic yield of 98%. The mean operating room length-of-stay and operating time were 73.7 and 42.5 min, respectively. Mean pLOS was 1.3 days with a low readmissions rate (3%). No mortality in the first 30 days due to acute exacerbation of ILD occurred. Both analgesia methods resulted in optimal feasibility with a mean NPRS score of 1.13. CONCLUSIONS: In undetermined ILD patients, surgical lung biopsy with a non-intubated VATS approach and spontaneous ventilation anesthesia appears to be both a practical and safe technique with an excellent diagnostic yield and high level of patient satisfaction.

HPLC-ESI-MS analysis of oral human fluids reveals that gingival crevicular fluid is the main source of oral thymosins beta(4) and beta(10).

Thymosin beta(4) (Tbeta(4)), its sulfoxide, and thymosin beta(10 )(Tbeta(10)) were detected in human saliva and identified by different strategies based on RP HPLC coupled to electrospray multidimensional IT MS. Tbeta(4 )was almost always detected in whole saliva, its sulfoxide sporadically, Tbeta(10) rarely. Tbeta(4) was undetectable in parotid saliva and less concentrated in submandibular/sublingual saliva than in whole saliva. Analysis of gingival crevicular fluid revealed high relative amounts of Tbeta(4), Tbeta(4) sulfoxide, and Tbeta(10) in all the samples. Tbeta(4) mean concentration was 200 times higher in crevicular fluid (20 micromol/L, N = 9) than in whole saliva (0.1 micromol/L, N = 9). Crevicular fluid concentration of Tbeta(4 )(ca. 5% represented by its sulfoxide) and beta(10 )significantly correlated (r = 0.856; N = 9), and their ratio was about 5. A significant correlation was also observed between Tbeta(4 )concentrations in whole saliva and gingival crevicular fluid (r = 0.738; N = 9). Immunohistochemical analysis of the major salivary glands showed that immunoreactivity for Tbeta(4) is restricted to ductal cells, with minor degree of focal positivity in some acinar cells. On the whole, results indicate that gingival sulcus is a main, although not the sole, source for oral Tbeta(4 )and Tbeta(10).

Lymphoepitelioma-like hepatocellular carcinoma: a case report and a review of the literature.

Lymphoepitelioma is a particular form of undifferentiated carcinoma, characterized by a prominent lymphoid stroma, originally described in the nasopharynx. Lymphoid stroma-rich carcinomas arising in other organs have been termed lymphoepithelioma-like carcinoma (LELC). In the liver, primary LELCs are very rare, and the majority has been identified as cholangiocarcinomas. Here a rare case of lymphoepithelioma-like hepatocellular carcinoma (HCC) is described. A 47-year old woman presented with abdominal pain. Ultrasonography revealed a liver nodule, 2.2 cm in diameter, localized in the right lobe, adjacent to the gallbladder. Viral markers for hepatic B virus (HBV), hepatic C virus (HCV) and Epstein-Barr virus (EBV) were negative. The nodule was hypoechogenic. The patient underwent surgery, with resection of the nodule. Histology showed hepatocellular carcinoma, characterized by a prominent lymphoid infiltrate. At immunocytochemistry, tumor cells were reactive for Hep Par1 and glypican 3. Immunophenotyping of tumor infiltrating lymphocytes evidenced the predominance of CD8+ cytotoxic suppressor T cells. The postoperative clinical outcome was favorable and the patient was recurrence-free 15 mo after resection. This case, to the best of our knowledge, is the first reported non EBV and non cirrhosis-associated lymphoepithelioma-like hepatocellular carcinoma. The association between the lack of EBV infection, the absence of cirrhosis, a "cytotoxic profile" of the inflammatory infiltrate and a good prognosis could identify a variant of lymphoepithelioma-like HCC with a favorable clinical outcome.

Deparaffination time: a crucial point in histochemical detection of tissue copper.

The search for a sensitive histochemical method for revealing tissue copper has been the object of many workers in the past. In spite of multiple methods available, the occurrence in clinical practice of negative histochemical stains, even in cases with high copper levels demonstrated by quantitative methods is very high.This study was aimed at verifying the role of technical variations in the sensitivity of the Timm method and, in particular, the role of the dewaxing time of paraffin sections. To this end, 15 liver specimens, 10 from patients affected by Wilson's disease and 5 newborn livers were fixed in 10% formalin, paraffin embedded and routinaly processed. Four 4-micron sections from each case were rinsed in xylene for 10, 20, 60 min, and for 24 hrs. All sections were stained with Timm's method. In 13 out of the 15 liver biopsies utilized in this study, the sensitivity of Timm's method in revealing copper deposits in liver cells appeared to be dependent on the dewaxing time. In two other cases, reactivity of copper granules to Timm solution did not change significantly with the different deparaffination times. The best results were obtained by rinsing sections in xylene for 24 hrs, the worst in sections treated with xylen for 10 minutes. In particular, in five cases of Wilson's disease, Timm stain applied to sections following ten minutes of xylene were completely negative, while copper granules were clearly evidenced in the same section following an overnight bath in xylene. Our data show that an overnight bath of paraffin sections in xylene may completely change the sensitivity of Timm stain in revealing copper deposits in the liver, relaunching copper histochemistry in the diagnosis of copper-related liver diseases.

Aluminum exposure and toxicity in neonates: a practical guide to halt aluminum overload in the prenatal and perinatal periods.

BACKGROUND: During the last years, human newborns have been overexposed to biologically reactive aluminum, with possible relevant consequences on their future health and on their susceptibility to a variety of diseases. Children, newborns and particularly preterm neonates are at an increased risk of aluminum toxicity because of their relative immaturity. DATA SOURCES: Based on recent original publications and classical data of the literatures, we reviewed the aluminum content in mother's food during the intrauterine life as well as in breast milk and infant formula during lactation. We also determined the possible role of aluminum in parenteral nutrition solutions, in adjuvants of vaccines and in pharmaceutical products. A special focus is placed on the relationship between aluminum overexposure and the insurgence of bone diseases. RESULTS: Practical points of management and prevention are suggested. Aluminum sources that infants may receive during the first 6 months of life are presented. In the context of prevention of possible adverse effects of aluminum overload in fetal tissues during development, simple suggestions to pregnant women are described. Finally, practical points of management and prevention are suggested. CONCLUSIONS: Pediatricians and neonatologists must be more concerned about aluminum content in all products our newborns are exposed to, starting from monitoring aluminum concentrations in milk- and soy-based formulas in which, on the basis of recent studies, there is still too much aluminum.
