Abstract
Ultratrace elemental detections from a limited volume of samples can offer significant benefits in biomedical fields. However, it can be challenging to concentrate the particles being analyzed in a small area to improve the accuracy of detection. Ring-like deposits on the edges of colloidal droplets are a vexing problem in many applications. Herein, we report ultratrace elemental detection using a superhydrophobic surface-enhanced laser-induced breakdown spectroscopy (SELIBS) substrate fabricated by laser ablation followed by a soft lithography technique. In this work, the SELIBS spectra on a superhydrophobic polydimethylsiloxane (PDMS) substrate replicated from a laser-patterned master Teflon substrate are investigated. This work highlights the application of this newly created superhydrophobic substrate for detecting trace elements in body fluids using SELIBS. The developed PDMS substrate was successfully adopted to investigate the electrolyte variation in serum samples of oral cancer patients and normal volunteers. Principal component analysis (PCA) and match-no-match analysis were used to distinguish the elemental variation in cancer and control groups.

Differential Expression of Genes Regulating Store-operated Calcium Entry in Conjunction With Mitochondrial Dynamics as Potential Biomarkers for Cancer: A Single-Cell RNA Analysis. Front Genet 2022; 13:866473. [PMID: 35711942 PMCID: PMC9197647 DOI: 10.3389/fgene.2022.866473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Accepted: 04/27/2022] [Indexed: 11/13/2022] Open
Abstract
Regulation of intracellular concentration of calcium levels is crucial for cell signaling, homeostasis, and in the pathology of diseases including cancer. Agonist-induced entry of calcium ions into the non-excitable cells is mediated by store-operated calcium channels (SOCs). This pathway is activated by the release of calcium ions from the endoplasmic reticulum and further regulated by the calcium uptake through mitochondria leading to calcium-dependent inactivation of calcium-release activated calcium channels (CARC). SOCs including stromal interaction molecules (STIM) and ORAI proteins have been implicated in tumor growth, progression, and metastasis. In the present study, we analyzed the mRNA and protein expression of genes mediating SOCs-STIM1, STIM2, ORAI1, ORAI2, ORAI3, TRPC1, TRPC3, TRPC4, TRPC5, TRPC6, TRPC7, TRPV1, TRPV2, TRPM1, and TRPM7 in head and neck squamous cell cancer (HNSC) patients using TCGA and CPTAC analysis. Further, our in silico analysis showed a significant correlation between the expression of SOCs and genes involved in the mitochondrial dynamics (MDGs) both at mRNA and protein levels. Protein-protein docking results showed lower binding energy for SOCs with MDGs. Subsequently, we validated these results using gene expression and single-cell RNA sequencing datasets retrieved from Gene Expression Omnibus (GEO). Single-cell gene expression analysis of HNSC tumor tissues revealed that SOCs expression is remarkably associated with the MDGs expression in both cancer and fibroblast cells.

Abstract
PURPOSE OF REVIEW This review describes the long scientific background followed to design guidelines and everyday clinical practice applied to melanoma patients. Surgery is the first option to cure melanoma patients (PTS) at initial diagnosis, since primary cutaneous lesions are usually easily resectable. An excisional biopsy of the lesion, with minimal clear margins, can be obtained in the vast majority of cases. Punch biopsies may be proposed only in case of large lesions located on specific cosmetic or functional areas like the face, extremities, or genitals where a mutilating complete resection would not be performed without prior histological diagnosis. RECENT FINDINGS After the histologic confirmation of melanoma, definite surgical excision of the scar and surrounding tissue is planned, to obtain microsatellite free margins. The width of these margins has been identified following the results of several clinical trials and it is either 1 or 2 cm, depending on the Breslow thickness of the primary tumor. Following the latest staging system proposed by the American Joint Cancer commission (AJCC), a sentinel node biopsy (SNB) is usually performed in case of a primary lesion > 0.8 mm thickness or for high-risk thinner lesions, if no evidence of nodal involvement has been identified clinically or radiographically. Surgical management of primary melanoma is well established. There is debate on the optimal surgical margins for 1-2 mm melanomas. There are specific considerations for special primaries (bulky, extremity, mucosal). Sentinel node (SN) evaluation does not improve survival, but is routinely used as staging.

Abstract
Objective: To evaluate the efficacy of induction chemotherapy in young adults with locally advanced oral squamous cell carcinoma (OSCC) and the usefulness of ERCC1 as a prognostic indicator. Methods: A total of 156 young adults with locally advanced OSCC were retrospectively analyzed from May 2007 to May 2017. Cisplatin based induction chemotherapy followed by surgery and upfront surgery were the primary treatment options for locally advanced OSCC. ERCC1 was evaluated by immunohistochemistry. Multivariate analysis was performed to identify significant prognostic factors for the overall survival (OS) in young adults with locally advanced OSCC. Results: Extracapsular spread (ECS) (p<0.0001) and UICC staging (p<0.0001) were critical prognostic factors for OS in young adults with locally advanced OSCC. The 5-year OS was 83.2% in N0 patients received induction chemotherapy and 61.7% in N0 patients received upfront surgery (p<0.05). Patients with a low ERCC1 expression were more likely to benefit from induction chemotherapy, as the 5-year OS was 22.4% in patients with a high ERCC1 expression and 84.7% in patients with a low ERCC1 expression, respectively (p<0.0001). However, induction chemotherapy resulted in a higher 5-year OS (84.7%) than upfront surgery (59.1%) in patients with a low ERCC1 expression (p=0.03). Conclusions: Induction chemotherapy can improve the outcome of N0 patients. However, the ERCC1 expression should be determined in young patients with locally advanced OSCC prior to induction chemotherapy, as it is a useful biomarker for predicting the outcome after induction chemotherapy.

Abstract
Introduction: Mucosal melanoma (MM) is a rare malignancy of the head and neck. Sinonasal melanomas are the most frequent, followed by oral melanomas. Observation: A 67-year-old patient with a known left sinus melanoma initially treated with immunotherapy was referred for consultation concerning mobile teeth. A pigmented lesion infiltrating the left maxillary arch in the molar area was detected. The malignancy had invaded the oral mucosa. Despite many proposed treatments (immunotherapy, chemotherapy, and radiotherapy), the patient showed metastatic progression, which resulted in death. Discussion: Sinus MMs are malignancies with poor prognosis because these are often diagnosed in the late stages of disease progression. As these tumors are rare, there is no treatment consensus and surgery remains the best option. Diagnosis of pigmented lesions of the oral mucosa is sometimes complicated because of various implied etiologies. Conclusion: This case report shows that sinus MMs can induce pigmentation in the oral mucosa. These are rare malignancies with poor prognosis, for which no treatment consensus exists to date.

Abstract
Undifferentiated sinonasal malignant melanoma (MM) is a rare type of tumor, which can be easily misdiagnosed. The present study reports a 41-year-old male patient who presented with a 4-day history of epistaxis. Clinical examination and radiological imaging lead to the detection of a mass in the right sinonasal region. Histopathological examination revealed that the mass was composed of malignant epithelioid cells arranged in nests and sheets. These cells displayed a hemangiopericytoma-like pattern with antler-like branching vessels. Immunohistochemical staining revealed that the tumor cells exhibited negative expression of melanocytic markers. This increased the difficulty of distinguishing undifferentiated MM from other malignant tumors located in the sinonasal area, particularly undifferentiated nasopharyngeal carcinoma. The diagnosis of undifferentiated MM was determined by ultrastructures, including the mature melanosomes and premelanosomes, in tumor cells by transmission electron microscopy. The present study suggests that the analysis of cancer stem cell marker and vasculogenic mimicry may be an important auxiliary tool for the diagnosis of MM.

Abstract
OBJECTIVE The optimal surgical approach for sinonasal mucosal melanoma (SNM) remains under debate. We aimed to compare the therapeutic efficacy of traditional open resection and endoscopic surgery for patients with SNM treated at a single center. METHODS Thirty-three patients diagnosed with SNM who underwent surgery between January 1995 and June 2014 at a single institution were retrospectively analyzed; 18 patients were treated using an open resection approach and 15 using an endoscopic resection approach for the primary tumor. The associations between open resection and endoscopic resection with treatment-related survival outcomes were assessed using the Kaplan-Meier method and log-rank test. RESULTS The most common presenting symptoms were epistaxis and abstraction; the nasal cavity was the most common anatomic location. The open resection and endoscopic resection groups did not have significantly different demographic or tumor characteristics. Overall survival (p = .66) and disease-free survival (p = .73) were modest and did not differ significantly between the open resection and endoscopic resection groups. CONCLUSIONS This retrospective study indicates that the endoscopic endonasal approach is an effective treatment for SNM in selected cases and, when performed by a skilled surgeon, can enable successful radical resection with a similar efficacy as traditional open resection.

Abstract
Hypercalcemia of malignancy (HCM) is a serious metabolic complication whose population‐based prevalence has not been quantified. Rates of HCM differ by tumor type, with highest rates reported in multiple myeloma and lowest among colorectal and prostate cancer patients. This analysis estimates HCM prevalence in the US. This retrospective study used the Oncology Services Comprehensive Electronic Records (OSCER) warehouse of electronic health records (EHR) including laboratory values from 569000 patients treated at 565 oncology outpatient sites. OSCER data were projected to the national level by linking EHR to claims data. Cancer patients included were ≥18 years, and had serum calcium (Ca) and albumin (for corrected serum Ca [CSC]) records. Period prevalence was estimated by HCM CTCAE grade, tumor type, and year (2009–2013). Estimates were adjusted to capture patients diagnosed with HCM outside oncology practices based on a subset of patients linkable to office and hospital data. The analysis included 68023 (2009) to 121482 (2013) cancer patients. In 2013, patients with HCM had a median of six Ca tests, 69.7% had chemotherapy, and 34% received bone modifying agents. HCM rates were highest for multiple myeloma patients (7.5% [2012]–10.2% [2010]), lowest for prostate cancer (1.4% [2012]–2.1% [2011]).The estimated adjusted annual prevalence of HCM from 2009 to 2013 was 95441, 96281, 89797, 70158, and 71744, respectively. HCM affected 2.0–2.8% of all cancer patients. EHR data from oncology clinics were critical for this study because these data contain results from laboratory studies (i.e., serum calcium values) that are routinely ordered in that setting. We estimated that the prevalence of HCM in the US in 2013 is 71744, affecting approximately 2% of cancer patients overall. This percentage differs by tumor type and appears to have decreased over the five‐year study period.

Prevalence of hypercalcemia of malignancy among cancer patients in the UK: analysis of the Clinical Practice Research Datalink database. Cancer Epidemiol 2015; 39:901-7.

Abstract
BACKGROUND The reported proportion of cancer patients who experience hypercalcemia of malignancy (HCM) ranges between 3% and 30%. HCM can be observed with any type of tumor and occurs most commonly in lung cancer, breast cancer and multiple myeloma. While HCM is a potentially fatal condition, the prevalence of HCM is not well defined. METHODS Using the United Kingdom Clinical Practice Research Datalink, we identified adult cancer patients with recorded corrected serum calcium (CSC). Hypercalcemic patients (CSC ≥ 10.8 mg/dL) were classified into 4 CSC levels. We estimated annual prevalence of HCM overall, stratified by cancer type, and in patients with stage IV cancer. RESULTS Among 37,442 cancer patients in 2003-2012 the prevalence of grade 1 HCM increased from 0.13% to 0.45% and the prevalence of HCM overall (grade 1 or higher) increased from 0.20% to 0.67% over the study period. Prevalence estimates varied across cancer type and were highest for lung cancer, multiple myeloma and patients with stage IV cancer. CONCLUSION We provide the first systematic analysis using a UK population-based data source to estimate number of cancer patients affected with HCM by grade. The increase in HCM prevalence over the 10-year study period is likely due to the increased recording of laboratory values, particularly comparing more recent data to 2003. Our findings suggest that HCM in general is not a common condition.

Abstract
BACKGROUND The purpose of this phase II trial was to evaluate the tolerability, safety, and efficacy of a non-5-fluorouracil (5-FU)-based induction chemotherapy followed by chemoradiotherapy (CRT) for patients with locally advanced head and neck squamous cell carcinoma (HNSCC). METHODS Sixty patients with stage III to IV HNSCC were treated with induction paclitaxel and cisplatin (TP; paclitaxel 175 mg/m(2) and cisplatin 80 mg/m(2) , 3 cycles) followed by CRT (cisplatin 100 mg/m(2) ; D1, 22, and 43 of radiotherapy). RESULTS Fifty-six patients (93.3%) completed 3 cycles of induction TP (no treatment-related deaths), 52 (86.7%) completed definitive CRT per protocol (adverse event [AE] grade ≥2 in 53.3%). The overall response rate after induction TP was 82.5% for patients with resectable disease and 55.5% for unresectable disease (p = .023), and complete response (CR) rate after CRT was 70.0% for patients with resectable disease and 30.0% for unresectable disease (p = .005). CONCLUSION Induction TP followed by cisplatin based-CRT was well-tolerated, safe, and had high overall response rate in selected patients with locally advanced HNSCC. © 2015 Wiley Periodicals, Inc.

Abstract
Background The significance of definitive radiotherapy for sinonasal mucosal melanoma (SMM) is sill controvertial. This study was to evaluate the role of high-dose proton beam therapy (PBT) in patients with SMM. Methods The cases of 20 patients with SMM localized to the primary site who were treated by PBT between 2006 and 2012 were retrospectively analyzed. The patterns of overall survival and morbidity were assessed. Results The median follow-up time was 35 months (range, 6–77 months). The 5-year overall and disease-free survival rates were 51% and 38%, respectively. Four patients showed local failure, 2 showed regrowth of the primary tumor, and 2 showed new sinonasal tumors beyond the primary site. The 5-year local control rate after PBT was 62%. Nodal and distant failure was seen in 7 patients. Three grade 4 late toxicities were observed in tumor-involved optic nerve. Conclusion Our findings suggested that high-dose PBT is an effective local treatment that is less invasive than surgery but with comparable outcomes.

Abstract
Sinonasal mucosal melanoma (SNMM) is associated with poor prognosis. Local recurrence is common and represents a major problem in the therapy. Wide resection surgery is usually applied. However, given the almost futile prognosis, optimal symptom control may be preferable to wide resection at all costs. The aim of our study was to analyze the outcome in patients with recurrent SNMM treated by transfacial radical surgery or by a less invasive endoscopically controlled approach. Patients with recurrent grade III or IV staged SNMM who presented to our ENT department between 2000 and 2010 were either treated by transfacial (n = 10) or endoscopically controlled surgery (n = 12). The patients' charts were reviewed for clinical symptoms, relapse-free time and survival time. Clinical symptoms improved after surgery. The morbidity after endoscopic surgery was significantly lower than after transfacial surgery. The chosen surgical technique did neither affect relapse-free nor survival time. When treating recurrent SNMM, the comparatively gentle and less mutilating endoscopic approach proved to be a sufficient surgical procedure, being not inferior to aggressive surgery with respect to recurrence and survival rate.

Abstract
Hypercalcaemia, a common complication of advanced cancer, causes multiple clinical symptoms, deteriorates patients' quality of life, and is associated with poor prognoses. This study aimed to identify the factors that may be associated with hypercalcaemia in advanced cancer by retrospectively reviewing the medical records of patients (n = 404) admitted to the palliative ward of the Kaohsiung Medical University Hospital, Taiwan, from 2006 to 2008. Patients' demographics, clinical data and symptoms were recorded. Seventy-nine of 404 patients had hypercalcaemia (19.6%), predominant in cases of head-and-neck cancer and haematological malignancies (P < 0.05), but not in those of bone metastases. Hypercalcaemia was associated with consciousness disturbances and leucocytosis (P < 0.05). We recommend that ionised (corrected) calcium levels be monitored clinically in patients with advanced cancer especially when consciousness disturbances are noted, or when head-and-neck or haematological malignancies are present. Testing of free calcium levels is also recommended in patients with leucocytosis.

Abstract
BACKGROUND Mucosal melanomas in the head and neck region are most frequently located in the nasal cavity and paranasal sinuses. Sinonasal mucosal melanoma (SNMM) comprises <1% of all melanomas. The aim was to determine the KIT, NRAS and BRAF mutation frequencies in a large series of primary SNMMs. METHODS Laser capture microdissection was used to isolate tumour cells from 56 formalin-fixed paraffin-embedded tumours. The tumour cells were screened for KIT, NRAS and BRAF mutations by direct sequencing. RESULTS Overall, 21% (12 out of 56) of SNMMs harboured KIT, NRAS or BRAF mutations. Mutations in these oncogenes occurred in a mutually exclusive manner. Both KIT and BRAF mutations were identified at a similar frequency of 4% each (2 out of 56), whereas NRAS mutations were detected in 14% (8 out of 56) of the SNMMs. Four of the NRAS mutations were located in exon 1. Mutations in these oncogenes were significantly more common in melanomas located in the paranasal sinuses than in nasal cavity (P=0.045). In a multivariate analysis, patients with melanomas in the nasal cavity had a significantly better overall survival than those with tumours in the paranasal sinuses (P=0.027). CONCLUSION Our findings show that KIT and BRAF mutations, which are accessible for present targeted therapies, are only rarely present in SNMMs, whereas NRAS mutations seem to be relatively more frequent. The data show that majority of SNMMs harbour alterations in genes other than KIT, NRAS and BRAF.

Abstract
Melanomas occurring in the tongue are rarer, and when nonpigmented they are often misdiagnosed as squamous cell carcinoma. We report a 50-year-old woman who presented with a 3 × 2 cm soft swelling of mucosal color on the right lateral border of the tongue. The patient had multiple recurrences and was treated by radical radiotherapy, was operated thrice and received adjuvant 5 MIU interferon weekly. During the last surgery, she developed multiple cerebral infarcts and died on the fifth postoperative day. Oral amelanotic melanoma is a very aggressive and potential lethal tumor that often presents as diagnostic dilemma.

Abstract
Objectives. Mucosal melanomas are rarer than their cutaneous counterparts and are associated with a poorer prognosis. We report the clinical outcomes of patients with mucosal melanomas of the head and neck region generally treated with definitive surgery followed by postoperative radiation therapy (RT). Methods. We reviewed the records of 17 patients treated at the University of Miami in 1990-2007. Patients generally received conventionally fractionated RT regimens to the postoperative bed. Elective nodal RT was not routinely delivered. Eight patients received adjuvant chemotherapy or immunotherapy. Results. Median followup was 35.2 months (range 5-225). As the first site of failure: 3 patients recurred locally, 2 regionally and 2 distantly. All 3 patients who recurred locally had not received RT. Of the 5 locoregional recurrences, 4 were salvaged successfully with multimodality therapy with no evidence of disease at last followup. Overall survival was 64.7% at 2 years and 51.5% at 5 years. Conclusions. Patients with mucosal melanoma of the head and neck are best treated with surgery to achieve negative margins, followed by postoperative RT to optimize local control. Elective nodal irradiation may not be indicated in all cases, as regional failures were not predominant. Distant metastases were fewer when compared to historical data, potentially due to advancements in adjuvant therapies as well as aggressive multi-modality salvage at time of failure.

Abstract
The aim of this study is to analyse survival and prognostic factors in patients diagnosed with squamous cell carcinoma (SCC) presenting a first episode of cancer-associated hypercalcaemia (CAH). Retrospectively, the authors reviewed data from 220 patients with biopsy proven SCC who presented a first episode of CAH. They were treated in a single centre between 1995 and 2007. The survival analyses were done using the Kaplan-Meier method and Cox analysis. The primary endpoint was the overall survival from the date of hypercalcaemia episode. Median age was 55 years. Median survival was 64 days (1-197). Three independent prognostic factors were identified: brain metastasis (hazard ratio (HR)=2.58 CI (1.03-6.45)), corrected calcaemia>3 mmol/l (HR=1.45 CI (1.05-2.01)) and hypoalbuminaemia (HR=1.48 CI (1.07-2.04)). Using these factors, the authors performed a bedside prognostic score. In conclusion, median survival in patients diagnosed with SCC and CAH is extremely poor. The bedside prognostic score that the authors developed can help to anticipate patients' prognosis and adapt the treatment. This score needs to be validated on an independent cohort.

Abstract
Primary mucosal melanoma is a biologically aggressive neoplasm, which is rarely located at the base of the tongue. The absence of early signs and symptoms, the lack of an evidence-based treatment, the early development of metastases and high rates of local recurrence contribute to the overall poor prognosis of these melanomas. This paper reports the case of a 66-year-old male presenting with local recurrence of a primary melanoma of the base of the tongue.

Abstract
Nasal mucosal melanoma presents usually with epistaxis, nasal obstruction and facial pain. However melanoma tends to give distant metastases at an early stage, having rare clinical presentations.
We present a 74-year old female patient with symptoms of central type vertigo caused by brain metastases. Clinical assessment for the detection of the primary site revealed a nasal mucosal melanoma originating from the posterior end of the left inferior turbinate. The patient received a combination of radio and chemotherapy being in relatively good condition 8 months later. This is the first reported case of a nasal mucosal melanoma with vertigo as the first presenting symptom.

Abstract
The diagnosis of a paraneoplastic syndrome (PNS) may precede, follow or be concurrent with the diagnosis of a malignant tumor. There is increasing knowledge of association between PNS and head and neck cancers, but the relationship between oral cancer and paraneoplastic disease has not been previously investigated. PNS associated with head and neck cancer can be divided into six main groups: endocrine, cutaneous or dermatologic, hematologic, osteoarticular or rheumatologic, neurologic, and ocular syndromes. We have comprehensively reviewed the literature to evaluate the incidence of occurrence of PNS with oral cancer, and conclude that only endocrine and dermatologic PNS have been associated with oral cancer. Humoral hypercalcemia is the most frequent PNS related to oral cancer, and has a negative prognostic significance. Dermatologic PNS are less common, but when they occur, they may precede the diagnosis of the oral tumor. Awareness of these conditions is important for clinicians who deal with cancer.

Abstract
OBJECTIVE The aim of this study was to determine the prevalence of oral malignant melanoma along with age range and site of presentation over an 11-year period in Iran. MATERIALS AND METHODS The files of Tehran Cancer Institute served as a source of material for this study. Files were systematically searched for all malignant melanomas and oral malignant melanomas during an 11-year period. Prepared slides and demographic data from the biopsy files were reviewed. Statistical analysis was performed with the use of SPSS. RESULTS Of the 38,993 cases accessed during the 11-year period, 569 were identified as malignant melanomas, while 41 cases among this group had malignant oral melanomas comprising 0.1% of the total cases and 7.2% of all the malignant melanoma lesions. CONCLUSION The palate was the most common location for oral malignant melanoma. Thus, all melanocytic lesions in the palate should be viewed with caution, and biopsy is recommended to rule out melanoma.

Abstract
OBJECTIVES To determine the value of technetium-99m bone scintigraphy in the screening of bone metastases in the systematic initial extension assessment of upper aerodigestive tract suamous cell carcinomas; to identify risk factors of these bone metastases for better screening. MATERIAL AND METHODS In this prospective study, the initial assessment of tumoral extension was systematically associated with bone scintigraphy. Only patients with no malignant tumors were included in the study. Any skeletal fixation identified was then analyzed with standard radiography and/or tomodensitometry and with the patient's clinical progression to confirm whether or not the fixation was metastatic. The sensitivity and specificity of bone scintigraphy was then calculated. A correlation between bone pain or hypercalcemia and confirmed bone metastases was also systematically sought to determine whether these factors were predictive of bone metastases so as to better target the screening. RESULTS Among the 55 patients included in the study, three had confirmed bone metastases. All were detected by the bone scintigraphy, with a sensitivity of 100%. However, the 20 false-positive results gave a low specificity of 62%. Bone pain was described by two patients, but they were among the three metastatic patients. Specificity was 100%, but the sensitivity was only 67%. Three patients had hypercalcemia: the three metastatic patients. The sensitivity and specificity were 100%. In the tumoral status of the three patients with bone metastasis, tumors were small, classified as T1 or T2, but with substantial node involvement, classified N3, and with invasion of the internal jugular vein in two cases. CONCLUSION The incidence of bone metastases in the initial extension assessment was low; consequently, they are not sought systematically. However, their presence radically changes the prognosis and the therapeutic management, raising the question of screening. The technetium-99m bone scintigraphy has limits, with many false-positive resulting the need for additional investigations. Defining the risk factors for bone metastases would improve screening. Two questions remain: what factors are involved? The bone pain and the hypercalcemia must be analyzed with a larger number of cases, but they seem to be nonspecific. The node involvement stage could be a more reliable parameter, in particular in cases of jugular vein invasion; what method should be used? In the future, the PET scan could be the key procedure not only in the locoregional extension assessment, but also for general extensions, in a single procedure investigating the whole body.
