Kenapa Perlu Islam Nusantara? (Sanggahan atas Tulisan KH. Idrus Romli)
Authors: Moh Sobirin
Published: March 2024

Sejak bergulirnya istilah Islam Nusantara ada banyak pihak yang menerima, dan ada pula pihak yang menentangnya. Di antara para penentangnya adalah KH. Idrus Romli yang menulis artikel berjudul Islam Nusantara, bolehkah diterima? Dengan demikian obyek kajian pada artikel ini adalah tulisan KH. Idrus Romli tentang Islam Nusantara. Artikel ini didasarkan pada studi kepustakaan (library research) dengan menggunakan metode deskriptif, teknis analisis isi, (contens analysis), dan  model analisis perbandingan (comparative study).

Hasil kajian menjelaskan bahwa Islam Nusantara adalah implementasi ajaran Islam ahlussunah wal jamaah di Nusantara dengan cara bermadzhab secara qauli (tekstual) dan manhaji (kontekstual) sehingga melahirkan Islam berwajah ramah, anti radikal, inklusif dan toleran, tidak ektrim kanan tapi juga tidak ektim kiri (liberal). Keberadaan Islam Nusantara digadang-gadang sebagai model Islam ideal di masa depan. Beberapa alasan yang mendasarinya dapat dilihat dari aspek historis, strategis dan normatif. Alasan ini sekaligus mementahkan argumen pengkritik bahwa Islam Nusantara tidak diperlukan. Alasan Historis ; 1) Pernah menjadi pusat studi keislaman 2)  Penyebaran Islam disampaikan dengan cara-cara damai. Alasan strategis ; 1) Menjadi magnet diskusi keislaman khas Nusantara 2) Mengukuhkan Identitas Ahlussuanah Wal Jama’ah (Aswaja). Penjelasan ini membalikan logika yang dibangun pengkritik bahwa Islam Nusantara dapat pengaburkan Aswaja. Alasan Normatif ; 1) Islam Nusantara lebih mengedepankan tujuan syari’at (Maqoshid Syari’ah). Pelabelan Nusantara dinilai memiliki banyak kemashlahatan (tujuan syari’at) baik dari sisi historis, strategis maupun normatif. Maka penilaian pengkritik bahwa Islam Nusantara merupakan serun jahiliyah yang dilarang adalah kurang tepat. 2)  Islam Nusantara membangun semangat persatuan dalam kebinekaan. Dalam hal ini Islam Nusantara mengusung tiga prinsip yaitu sikap tawassuth dan I’tidal (moderat), sikap tasamuh (toleransi), dan sikap tawazun (keseimbangan). Sikap tawasuth yang diinterprestasikan KH. Ma’ruf Amin pada dasarnya adalah agar umat tidak terjebak pada dua sikap yang eksrtim yaitu sikap ghuluwwun ; kolot atau radikal dan sikap taqshir ; meremehkan atau bebas tanpa aturan (liberal). Dengan demikian tuduhan Islam Nusantara mengusung Islam liberal adalah tuduhan yang tidak berdasar. Studi ini berkesimpulan Islam Nusantara adalah bentuk implementasi ajaran Ahlussunah wal Jama’ah di Nusantara. Munculnya  kritikan lebih disebabkan minimnya pemahaman pengkritik tentang konsep Islam Nusantara sehingga argumentasi yang dibangun atas dasar kecurigaan, kurang cermat, akurat dan proposional
Cadar: Sebuah Syari’at ataukah Budaya? Kontekstualisasi Abdullah Sa’ed

Problematikan seputar cadar adalah pembicaraan yang selalu menarikdi tengah keragaman masyarakat kita, beberapa problem yang munculbelakangan ini adalah rencana pelarangan ASN (Aparatur SipilNegara) untuk memakai cadar dan munculnya fenomena cross hijaberyang dianggap cukup meresahkan masyarakat. Sebenarnya tidakhanya baru-baru ini wanita bercadar menuai pro dan kontra. Sejakdulu ulama klasik bahkan di antara mereka memiliki pendapat yangberbeda terkait pakaian wanita secara umum, dan kewajiban wanitamenutupi wajahnya khususnya. Perbedaan ulama berangkat dari alAhzab 59 dan Nur 31 yang mana ketentuan masalah dan hukum tidakpasti (mutasyabihat), masih memiliki berbagai kemungkinan hukumdan tasyri', apalagi perbedaan diperkuat oleh sumber hukum kedua,yaitu Hadits Nabi. Para komentator tidak bisa masuk satu arahmenetapkan hukum kerudung perempuan dalam syari'at. Penelitianini merupakan studi pustaka (studi kepustakaan) dengan metodepenyajian analisis deskriptif itu mencoba untuk menggambarkankonsep yang terkandung dalam Alquran dengan menggambarkanmakna yang terkandung oleh ayat-ayat yang dipelajari serta pendapatpara Mufassir dan kemudian disjikan dan di analisis dengan metodeyang ditawarkan oleh Abdullah Saed. Hasil dari penelitian inimenemukan bahwa kekontroversionalan cadar telah terjadi sejakdahulu. Para ulama dan pakar tafsir sudah mendiskusikan seputarhukum bercadar apakah wajib menutup wajah mengunakan cadar atauhanya sebatas sunnah. Banyak kalangan mufassir yang berkesimpulanbahwa cadar bukanlah sebuah kewajiban dengan amembangunargumen bahwasanya wajah bukan termasuk aurat maka tidak wajibuntuk ditutupi. Sedangkan sebagian mufassir lain mewajibkanpengunaan cadar karena menganngap bahwa wajah adalah bagian dariaurat wanita yang harus ditutupi.

Published: March 2024

The implementation of Intellectual Property Rights (IPR) at Padang State Polytechnic (PNP) is the main focus in responding to the needs of the industry and the dynamics of globalization. This article highlights the crucial role of IPR protection in the context of research, community service, and innovation in the university environment. Despite providing positive incentives for faculty to innovate, data management at the PNP IPR Center remains limited, especially in the use of social media and department announcements. To overcome these constraints, a 4-month community service initiative was implemented using the Research & Development (R&D) method. The process includes data analysis, design of an information system, prototype development, testing, implementation, and continuous monitoring. The implementation of the IPR Center information system at PNP is expected to enhance efficiency, effectiveness, and the positive impact of IPR on campus, strengthening the role of the university as a positive agent of change, and optimizing the utilization of knowledge and innovation for community well-being. This abstract comprehensively summarizes the relationship between IPR, research, community service, and innovation in higher education

Published: March 2024

Even in the most pristine groundwater, all naturally occurring trace elements are found in varying concentrations. Some of these elements are essential for human health (e.g., molybdenum), others are benign (e.g., strontium), and still others are potentially toxic (e.g., lead). Added to these naturally occurring trace elements are those introduced anthropogenically. To quantify and understand the impacts of various human activities on groundwater quality, it is vital to establish reliable background concentrations of trace elements for comparison. In this book, we describe work conducted at the Elmvale Groundwater Observatory, a dedicated research facility for sampling pristine, flowing, artesian groundwater while minimizing the risk of sample contamination. We summarize the experience we have gained to date regarding selection of well construction materials, the design and use of laminar-flow, clean-air cabinets, and the importance of appropriate plastic sampling bottles and cleaning procedures—measures intended to minimize trace elements in blank samples (i.e., samples containing distilled water). The book includes a summary of trace element concentrations in pristine groundwater that will be useful for other studies. In addition to providing context and perspective, values in the summary also function as reference levels to allow comparison to pristine groundwater concentrations.
The prevalence factor of post-traumatic stress disorders among students of Mariupol
Authors: Bogachev Aleksei Mikhailovich , Ermakova Natal'ya Georgievna
Published: March 2024

The subject of the study is post-traumatic stress disorder (PTSD) of people exposed to stress factors in the city of Mariupol during the active phase of the Special Military Operation in the city. Taking into account the tasks of socio-psychological rehabilitation of the civilian population located in an area of increased risk of psychological and physical trauma, identifying the level of prevalence of PTSD in Mariupol is extremely relevant from both a scientific and applied point of view. Obtaining relevant information is important both for further in-depth research and for the development and implementation of appropriate programs of socio-psychological and (or) depth psychological rehabilitation. In addition, this information is relevant in the context of solving the problem of forming the all-Russian civic identity among new generations of Russians. The study used structured clinical interview technology, as well as the Clinical-Administered PTSD Scale (CAPS) and a PTSD screening questionnaire. Based on the data obtained during the study, it was concluded that, in comparison with similar indicators identified among the civilian population of Afghanistan and Chechnya, who were in the territory of intense military operations and experienced the effects of powerful stress factors, as well as among people who witnessed the shooting of the Russian parliament in 1993, the prevalence of PSTD among residents of Mariupol who were in the city during the operation to liberate it is quite low. In the opinion of the authors of the article, this fact is explained by the fact that the majority of Russian citizens who remained in Mariupol and returned to it perceive the military actions of 2022 as a “forced necessity”. This leads to the conclusion about the extreme importance of using psychological and psychological-pedagogical technologies in the sphere of protecting traditional values.
On the characterization of rectangular duals
Authors: Kumar Vinod ,   Department of Mathematics, BITS Pilani, Shekhawat Krishnendra ,   Department of Mathematics, BITS Pilani
Published: March 2024

A rectangular partition is a partition of a rectangle into a finite number of rectangles. A rectangular partition is generic if no four of its rectangles meet at the same point. A plane graph G is called a rectangularly dualizable graph if G can be represented as a rectangular partition such that each vertex is represented by a rectangle in the partition and each edge is represented by a common boundary segment shared by the corresponding rectangles. Then the rectangular partition is called a rectangular dual of the RDG. In this paper, we have found a minor error in a characterization for rectangular duals given by Koźmiński and Kinnen in 1985 without formal proof, and we fix this characterization with formal proof.
Clinical Presentation, Approach and Outcome of Gliosarcoma: A Series of 12 Cases
Authors: Singh Shreya , Mishra Ritusha , Naik Bitan , Shah Manav , Mishra Himanshu
Published: March 2024

Gliosarcoma (GSM) is a rare and aggressive type of brain tumour with limited treatment options and a poor prognosis. The present case series aimed to provide further insights into the clinical features, treatment outcomes, and prognosis of GSM. Medical records of 12 histologically confirmed cases of GSM were analysed from 2018 to 2022, revealing a male predominance and a median age of 54 years. The most common symptoms were headache and vomiting due to raised intracranial pressure. All patients underwent maximal safe resection followed by concurrent chemoradiation and adjuvant chemotherapy with Temozolomide (TMZ). KaplanMeier analysis showed a median Progression-free Survival (PFS) and overall survival of 8 and 12 months, respectively. The study revealed that the optimal treatment for primary GSM remains a therapeutic dilemma due to the rarity of the disease and the heterogeneity of the patient population and treatment regimens employed. The present study provides valuable insights into the clinical presentation and management of primary GSM in India and highlights the need for further research to improve outcomes for these patients.

Raoultella ornithinolytica (R. ornithinolytica), a Gram-negative bacillus, has characteristics resembling those of Klebsiella spp. This bacterium is present in soil and aquatic environments and seldom causes Healthcare-Associated Infections (HAIs). However, clinical features and outcomes of human infections caused by R. ornithinolytica have been reported for only a limited number of cases. Here, multiple cases of adult patients with clinical features of community-acquired infections at different body sites are presented. R. ornithinolytica was identified in the laboratory from respective samples sent for culture and sensitivity. These patients were treated with good outcomes. R. ornithinolytica is a saprophyte known to cause secondary infections in patients with risk factors and sometimes exhibits antibiotic resistance. However, all the patients presented to the institution recovered fully from the infections and were discharged.

Published: March 2024

This research aims at introducing the Grow My Fish application (or app) as an IoT for collecting and processing data on water quality in biofloc tank for cultivators. IoT in itself has been widely used by several sectors, and one of them is the fisheries sector. Grow My Fish is an app specifically designed to support research in the fisheries field. This research was conducted in Apung Village, Tanjung Selor District, Bulungan Regency from October through December 2023. Biofloc is an innovation in fisheries field. It is known as an eco-friendly innovation thanks to its ability to process the wastes produced by fish into natural feed in the assistance of the probiotic that was mixed into the water. However, the persistent main issue until recently in this biofloc innovation is water quality. Many cultivators so far recorded their water quality measurements on a book. This made it a little hard for these cultivators to process the data. For this reason, an IoT that facilitated cultivators in processing the data on water quality, mortality, fish weight, and amount of feed was born.

Challenges and Reflections of Black Nurses in Mental Health: Navigating between Colonialist and Decolonial/Ancestral Paradigms
Authors: Silva Luciana Silvério Alleluia Higino da , Tavares Claudia Mara de Melo , Silva Thiago Nogueira
Published: March 2024

Introduction: Racism is considered to permeate the lives of the black population, with black nurses standing out in this context, across different stages of life, causing illness of all kinds, including mental illness. Objectives: Thus, this article aimed to understand the academic and professional experiences of black nurses working in mental health and how they perceive their care from the ancestral decolonial perspective. Methods: It was a sociopoetic qualitative study, conducted with nine black nurses working in mental health in the state of Rio de Janeiro in May 2023, with data produced in a meeting through collective construction on decolonial care, where after transcription of the audios, they were categorized with the support of MAXQDA software (2022), and the research was submitted to the Research Ethics Committee (REC) with CAAE–48959421.1.3001.5279 and approved with opinion no. 5,555,653. Results: The statements of the black nurses who participated in the sociopoetic experimentation resulted in three categories: 1) Racism as a barrier to access in academic training, 2) The experience of being a black nurse in everyday work, and 3) Decolonial/ancestral care as resistance. Discussion: Certainly, nursing education needs to be reorganized; since its inception, its theoretical-practical reading has been based solely on a single worldview, or rather, focused on caring for a single reference of "human being". Hence the need to rethink and incorporate multicultural concepts and care practices that can overcome all structures that sustain racism in contemporary society. Conclusions: Phenotypic prejudice, in addition to preventing different people from ensuring the right to access and opportunities, leads numerous professionals to suffer physically and mentally or to give up their careers. Nursing and mental health need to be prepared for current and future challenges in a world that is becoming more diverse every day. Finally, it is important for other studies to address this issue until racism is eradicated from society and especially from nursing.

COVID-19 Infection in Pregnancy: A Case Series from Derna, Libya
Authors: Ajroud Soad , Elzahaf Raga A.
Published: March 2024

Introduction: Pregnant women are potentially a high-risk population during infectious disease outbreaks such as COVID-19, because of physiologic immune suppression in pregnancy. However, data on the morbidity and mortality of COVID-19 among pregnant women, compared to nonpregnant women, are lacking. We sought to describe the management of twenty-one pregnant women with COVID-19 infection.

Methods: A prospective chart review was conducted to identify pregnant women who presented with symptom and sign of COVID- 19 and tested positive or highly suspected even if test was negative, from 15 June 2020 to 04 October 2021.

Results: Four women required non-invasive supplemental oxygen therapy and one required mechanical ventilation. One woman had a pulmonary embolism and expired after delivery.

Conclusion: Management of pregnant women with severe COVID-19 is complex and should involve multidisciplinary expertise. Avoiding early delivery may be a safe option. We recommend an individualized approach to care, including careful consideration of the expected risks and benefits of expectant obstetric management versus delivery.

Bubbly flow through fixed beds: Microscale experiments in the dilute regime and modeling
Authors: Bordas M. L. , Cartellier A. , Sechet P. , Boyer Ch.
Published: October 2006

In order to predict the pressure drop and the mean void fraction for bubbly flows in packed beds, a new one‐dimensional (1‐D) model is proposed. The balance equations for both phases are derived from local Eulerian two‐fluid equations which are spatially averaged at a mesoscale, that is, at a length‐scale large compared with the microscale that characterizes the fixed bed. This model, that differs from previous mechanistic models, has been supplemented by closure laws for the liquid‐solid and the gas‐liquid interactions, those structures account for the flow dynamics at the pore scale. It is first experimentally demonstrated that, in dilute conditions, the bubble‐size distribution only depends on the pore size, when the later is smaller than the capillary length scale. It is also shown that the mean‐bubble dynamics is similar to that of a slug, with a relative velocity at mesoscale linearly increasing with the liquid superficial velocity. Besides, that relative velocity monotonically increases with the gas flow rate ratio, a behavior that can be attributed to the formation of preferential paths for the gas phase. Concerning the liquid‐solid interactions, the two‐phase flow pressure drop scaled by its single‐phase flow counterpart at the same superficial liquid velocity is predicted to linearly increase with the void fraction, with a prefactor evolving with the Capillary number. These closures prove consistent with available experiments, both in upward and in downward situations. Although these proposals deserve to be further tested over an extended range of flow parameters, this model paves the way to reasonably accurate predictions of bubbly flows in packed beds able to account for refined parameters related with the flow dynamics. © 2006 American Institute of Chemical Engineers AIChE J, 2006

Published: October 2006

We report on a female infant presenting with psychomotor retardation and facial dysmorphism. Cytogenetic studies showed an abnormal chromosome 14 with ectopic NOR sequences at the extremity of the long arm with a terminal 14q32.33 deletion. Review of the eight cases with pure terminal 14q32.3 deletions described to date documented that our observation is the smallest terminal 14q deletion ever reported. Thus, genotype–phenotype correlation allows us to delimit the critical region for mental retardation, hypotonia, epi‐telecanthus, short bulbous nose, long philtrum, thin upper lip, and small mouth observed in 14 qter deletions to the subtelomeric 1.6 Mb of chromosome 14. © 2006 Wiley‐Liss, Inc.
Attitudes and beliefs of pediatricians and genetic counselors regarding testing and screening for CF and G6PD: Implications for policy
Authors: Koopmans Joy , Hiraki Susan , Ross Lainie Friedman
Published: October 2006

There is wide variability in conditions included in state newborn screening (NBS) panels. The American College of Medical Genetics (ACMG) was commissioned by Health Resources and Services Administration to develop a uniform NBS panel. Based on survey data, the ACMG committee proposed a panel that included cystic fibrosis (CF) and glucose‐6‐phosphate dehydrogenase deficiency (G6PD), although G6PD was excluded from their final recommendations. We examine the attitudes of pediatricians and genetic counselors concerning screening for these two conditions. Data were collected as part of two different studies. Koopmans and Ross surveyed a random sample of 600 pediatricians from four states based on their NBS panels. Hiraki et al. surveyed genetic counselors who were members of the National Society of Genetic Counselors (NSGC) listserv. For this analysis, we compare the health care professionals' (HCPs') attitudes toward a universal NBS program for CF and G6PD, and how their support is influenced by state policy and personal interest in testing their own children. Two hundred twenty‐three pediatricians and 267 genetic counselors provided partial or complete responses. Pediatricians are more likely to support NBS for both CF (84%) and G6PD (58%) than genetic counselors (56%,P < 0.001 and 39%,P < 0.001, respectively). Both pediatricians and genetic counselors' attitudes toward screening correlate with interest in screening their own children (P < 0.001). Interest in CF screening also correlates with state policy (pediatricians,P < 0.001; genetic counselors,P < 0.025). The correlation of professional recommendations with state policies and personal preferences reinforces the need for systematic evidence‐based reviews rather than reliance on stakeholder opinions for developing national guidelines. © 2006 Wiley‐Liss, Inc.

Recent technical advances in mass spectrometry (MS) have propelled this technology to the forefront of methods employed in metabolome analysis. Here, we compare two distinct analytical approaches based on MS for their potential in revealing specific metabolic footprints of yeast single‐deletion mutants. Filtered fermentation broth samples were analyzed by GC‐MS and direct infusion ESI‐MS. The potential of both methods in producing specific and, therefore, discriminant metabolite profiles was evaluated using samples from several yeast deletion mutants grown in batch‐culture conditions with glucose as the carbon source. The mutants evaluated were cat8, gln3, ino2, opi1, and nil1, all with deletion of genes involved in nutrient sensing and regulation. From the analysis, we found that both methods can be used to classify mutants, but the classification depends on which metabolites are measured. Thus, the GC‐MS method is good for classification of mutants with altered nitrogen regulation as it primarily measures amino acids, whereas this method cannot classify mutants involved in regulation of phospholipids metabolism as well as the direct infusion MS (DI‐MS) method. From the analysis, we find that it is possible to discriminate the mutants in both the exponential and stationary growth phase, but the data from the exponential growth phase provide more physiological relevant information. Based on the data, we identified metabolites that are primarily involved in discrimination of the different mutants, and hereby providing a link between high‐throughput metabolome analysis, strain classification, and physiology.

Published: October 2006

Background

The clinical relevance of splanchnic artery stenosis is often unclear. Gastric exercise tonometry enables the identification of patients with actual gastrointestinal ischaemia. A large group of patients with splanchnic artery stenosis was studied using standard investigations, including tonometry.

Methods

Patients referred with possible intestinal ischaemia were analysed prospectively, using duplex imaging, conventional abdominal angiography and tonometry. All results were discussed within a multidisciplinary team.

Results

Splanchnic stenoses were found in 157 (49·7 per cent) of 316 patients; 95 patients (60·5 per cent) had one-vessel, 54 (34·4 per cent) two-vessel and eight (5·1 per cent) had three-vessel disease. Chronic splanchnic syndrome was diagnosed in 107 patients (68·2 per cent), 54 (57 per cent) with single-vessel, 45 (83 per cent) with two-vessel and all eight with three-vessel stenoses. Treatment was undertaken in 95 patients, 62 by surgery and 33 by endovascular techniques. After a median follow-up of 43 months, 84 per cent of patients were symptom free.

Conclusion

Gastric exercise tonometry proved crucial in the evaluation of possible intestinal ischaemia. Comparing patients with single- and multiple-vessel stenoses, there were significant differences in clinical presentation and mortality rates.

Published: October 2006

Palsy of the external branch of the superior laryngeal nerve (EBSLN) during thyroid surgery is an important complication reported with varying frequency. This study was carried out to investigate the relationship between the EBSLN, the upper part of the thyroid gland and the inferior constrictor muscle of the pharynx (IC), and also to define consistent landmarks for identifying and preserving the EBSLN. Forty neck halves of 20 cadavers were dissected. Measurements were obtained between the crossing point of the EBSLN with the superior thyroid artery (STA) and the upper pole of the thyroid gland, the point where EBSLN penetrates the IC and the inferior thyroid tubercle, and the middle point of the oblique line of the thyroid cartilage, and the EBSLN. In 22.5%, the EBSLN crossed the STA more than 1 cm above the upper pole of the thyroid gland (Type I of Cernea et al. [1992a] Head Neck 14:380–383). In 60%, the EBSLN crossed the STA less than 1 cm above the upper pole of the thyroid gland (Type IIa of Cernea et al. [1992a] Head Neck 14:380–383). In 17.5%, the EBSLN crossed the STA under the upper pole of the thyroid gland (Type IIb of Cernea et al. [1992a], Head Neck 14:380–383). In 22.5%, the full course of the nerve was superficial to the IC (Type 1 of Friedman et al. [2002] Arch Otolaryngol Head Neck Surg 128:296–303). In 67.5%, the nerve penetrated the IC (Type 2 of Friedman et al. [2002] Arch Otolaryngol Head Neck Surg 128:296–303). In 10%, the nerve could not be identified at the lateral side of the IC (Type 3 of Friedman et al. [2002] Arch Otolaryngol Head Neck Surg 128:296–303). In conclusion, it is possible to identify the nerve superficial to the IC in 90% of specimens on average. Knowledge of the relationship between the EBSLN, IC, inferior thyroid tubercle, oblique line of the thyroid cartilage and the sternothyroid muscle will be useful for the surgeon in avoiding unexpected complications.

Published: October 2006

BACKGROUND.

An open‐label Phase II study of oxaliplatin was conducted to evaluate its safety and efficacy in children with recurrent or refractory medulloblastoma (MB), supratentorial primitive neuroectodermal tumors (SPNET), and atypical teratoid rhabdoid tumor (ATRT).

METHODS.

Patients were stratified as follows: stratum IA, first recurrence MB with measurable disease; IB, recurrent MB with only cerebral spinal fluid (CSF) positivity or linear leptomeningeal disease (LLD); IC, MB ≥second recurrence; stratum II, recurrent SPNET; stratum III, recurrent ATRT. Patients received oxaliplatin, 130 mg/m2 intravenously over 2 hours every 3 weeks. The primary objective was to estimate the sustained response rate in stratum 1A. Plasma ultrafiltrate platinum pharmacokinetics were evaluated.

RESULTS.

A total of 43 patients with a median age of 8.5 years (range, 0.6–18.9 years) were enrolled. In stratum 1A, 2 of 15 had partial responses (PRs, 1 sustained PR). No responses were observed in other strata. The most frequent Grade 3 and 4 toxicities included thrombocytopenia (25.6%), neutropenia (16.3%), leukopenia (12%), increase in serum alanine transaminase (ALT) (7%), vomiting (4.7%), and sensory neuropathy (4.7%). No severe ototoxicity or nephrotoxicity was reported. Plasma ultrafiltrate platinum pharmacokinetic parameters were similar to adults, with a median clearance of 12.2 L/hr (range, 4.4–30 L/hr) and median area under the curve (AUC0‐∞) of 9.4 μg/mL/hr (range, 6.2–13.9 μg/mL/hr).

CONCLUSIONS.

Oxaliplatin was well tolerated in children but has limited activity in children with recurrent CNS embryonal tumors previously treated with platinum compounds. Cancer 2006. © 2006 American Cancer Society.
Coupling of acetonitrile deproteinization and salting‐out extraction with acetonitrile stacking for biological sample clean‐up and the enrichment of hydrophobic compounds (porphyrins) in capillary electrophoresis
Authors: Li Qi , Huie Carmen W.
Published: October 2006

A new sample pretreatment approach in CE was developed for concurrent biological sample clean‐up and the concentration of hydrophobic compounds based on the combination of ACN deproteinization with salting‐out extraction. Further enhancement in concentration detection sensitivity was achieved by coupling (offline) salting‐out extraction with an online CE sample enrichment technique known as “ACN stacking”. By optimizing the pH of salting‐out extraction, a number of model compounds (hydrophobic porphyrins with clinical significances), i.e. zinc‐protoporphyrin, protoporphyrin, and coproporphyrin (CP) III and I, can be efficiently extracted from the aqueous sample into a smaller volume organic solvent (ACN) phase and an enrichment factor of ca. 100 can be obtained. The pressure injection of the enriched ACN phase (containing ca.1% NaCl) into the CE capillary at 10% capillary volume resulted in additional concentration of the various hydrophobic porphyrins, allowing for a combined enrichment factor of ca.1000 to be obtained. Calibration curves obtained for the determination of a pair of positional isomers with significant diagnostic value, urinary CPIII and CPI, were found to be linear between 10–300 ng/mL (with R2 = 0.999), and LODs (absorbance detection at 400 nm) were ca. 0.8 ng/mL (1.1 nmol/L of CPIII or CPI). Based on a single salting‐out extraction, intraday precisions (nine consecutive injections) for both CPIII and CPI (at spiked concentrations of 10–300 ng/mL into urine) in terms of migration time and peak area were found to be within the range of 0.2–0.5 and 0.8–2.9%, respectively.

Published: October 2006

Background.

This study reports our experience with fasciocutaneous reconstruction of circumferential pharyngoesophageal defects using an anterolateral thigh flap wrapped around a salivary bypass tube.

Methods.

The charts of 14 patients were reviewed. All patients who had reconstruction of a pharyngoesophageal defect using an anterolateral thigh flap with a salivary bypass tube between 2001 and 2005 were included.

Results.

There were 10 men and 4 women (mean age, 61 years). There were no fistulae reported, and the stricture rate was 14%. Eleven patients achieved oral diet sufficient to have the gastrostomy or jejunal tube removed. The patients who had tracheoesophageal puncture for voice developed functional speech. There were no flap losses. However, problems with salivary tube migration in the early cases have led to technique refinement.

Conclusions.

The low complication rates and the excellent functional outcomes make the anterolateral thigh flap in combination with a salivary bypass tube a viable option for reconstruction of these difficult defects. © 2006 Wiley Periodicals, Inc. Head Neck, 2006
Transoral resection of thyroid cancer metastasis to lateral retropharyngeal nodes
Authors: Shellenberger Thomas , Fornage Bruno , Ginsberg Lawrence , Clayman Gary L.
Published: October 2006

Background.

Lymph node metastasis from differentiated thyroid carcinoma may occur outside of the basins at greatest risk of spread, such as the lateral retropharyngeal lymph nodes. The extensive surgery of traditional approaches to the retropharyngeal space are rarely justified in the treatment of metastatic differentiated thyroid cancer. Therefore, a less invasive surgical approach is advantageous in resection of metastatic lateral retropharyngeal nodes.

Methods.

To assess feasibility and safety, we report transoral excision guided by preoperative ultrasonography in a series of 3 consecutive patients with differentiated thyroid cancer metastatic to the retropharyngeal space.

Results.

In all cases, the metastatic lateral retropharyngeal lymph node was successfully removed by transoral retropharyngotomy without complications.

Conclusions.

We advocate a transoral approach guided by preoperative ultrasonography for resection of differentiated thyroid cancer metastatic to the retropharyngeal lymph nodes. The approach is feasible, minimally invasive, and safe in achieving the goals in management of regionally metastatic disease. © 2006 Wiley Periodicals, Inc. Head Neck, 2007
