A rare case of advanced abdominal pregnancy with good maternal and fetal outcome
Authors: Agarwal Akanksha , Bansal Ramandeep , Sikka Pooja , Katoch Tanvi , Gupta Nalini
Published: March 2024

Advanced abdominal pregnancy is an uncommon and potentially precarious variant of ectopic pregnancy in which the fetus develops in the abdominal cavity. A 30-year-old multigravida presented at 33+5 weeks of gestation with abdominal pain. Ultrasonography revealed a single live fetus lying in the abdominal cavity, with the uterus seen separately. Previous ultrasonography done at 15 weeks of gestation was suggestive of intrauterine pregnancy. She underwent emergency laparotomy at 33+6 weeks, which confirmed secondary abdominal pregnancy with the placenta deriving its blood supply from the left uterine artery and omental vessels. A peripartum hysterectomy was performed. The postoperative period was uneventful, and both mother and baby were discharged after one week. Despite notable advancements in prenatal care and medical imaging technologies, abdominal pregnancies, even if advanced, may remain undiagnosed, emphasizing the necessity for healthcare professionals to maintain a heightened level of suspicion regarding this condition. If conservative management has to be sought, the case selection should be done carefully due to the high risk to both the mother’s and fetus’s life. There is a pressing need for the standardisation of treatment protocols in order to optimise maternal and fetal outcomes in abdominal pregnancy.

Published: March 2024

Background: Premenstrual syndrome (PMS) is a menstrual disorder defined as a cluster of various physical, emotional, and behavioural symptoms that negatively affect women’s quality of life. This cross-sectional study aimed to assess the prevalence of common PMS symptoms and determine their association with body mass index (BMI), lifestyle, dietary habits, perceived stress, menstrual flow, family history and family income among medical students at Al-Andalus University in Syria.
Methods: A sample of 205 female students were interviewed and filled out a questionnaire. All data were coded and entered into excel (Microsoft 2019). One-way analysis of variance (ANOVA) and Chi-square tests were used to evaluate the association between PMS symptoms and the studied factors.  
Results: The most frequently reported PMS symptoms were anxiety (80%), bloating (74.6%), and breast tenderness (62.9%). Our study found a significant association between weight gain pre-menstruation and BMI (p=0.02). A significant relationship was found between increased premenstrual consumption of sweets and both breast tenderness and bloating (p=0.01). Daily consumption of coffee was significantly correlated with weight gain and headaches (p<0.001). This study found a significant relationship between smoking cigarettes and abdominal and back pain (p=0.04, p=0.02, respectively). Smoking shisha was significantly associated with fatigue and bloating (p=0.01, p<0.001, respectively). A significant relationship was found between menstrual flow and both abdominal pain and headaches (p=0.01, p=0.02, respectively).
Conclusions: A high prevalence of PMS symptoms was reported in Al-Andalus University female medical students. Additionally, this study found multiple significant associations between BMI, dietary habits, lifestyle, menstrual flow and the severity of symptoms.

Atypical electroclinical presentation of Landau Kleffner syndrome: a case report of an 8 year old Nigerian child
Authors: Nwala Chuks G. , Ejemierele Omokhuale M.
Published: March 2024

Epileptic seizures account for common neurologic presentations in paediatric neurology units in developing countries. Atypical presentation of syndromic epilepsy may be missed especially sensory, psychic or autonomic manifestations. An 8 year old male Nigerian child presented with recurrent vomiting and delayed motor milestones, regression of speech (acquired aphasia) with unremarkable birth history or any underlying medical or surgical condition. He had delayed gross motor development and continuous bilateral polyspike waves of slow sleep on EEG. Self-limited autonomic epileptic seizure syndrome which was a strong differential of autonomic seizures in early childhood was not suggestive as his EEG findings failed to demonstrate occipital spike wave pattern nor did photic stimulation evoke any epileptiform waves. Child made significant clinical improvement with anticonvulsants, neuro vitamins, and behavioural therapy, evidenced by regain of non-verbal communication, resolution of autonomic symptoms and temper tantrums. A high index of suspicion should be applied in patients with acquired aphasia with subclinical or recurrent autonomic symptoms.
Trofinetide providing a promising avenue for the treatment of Rett syndrome
Authors: Devendar Raja , Shigri Anum Fatima , Khan Maheera
Published: March 2024

Rett syndrome (RTT) is a developmental disability associated primarily with the abnormal functioning of the nervous system. Affecting 1 in 10,000-15,000 women, it results from an inactivating modification in the X-linked genetic code, methyl-CpG-binding protein 2 (MECP2), which codes for a protein that binds to DNA and regulates transcription. Girls with RTT are born with normal prenatal and perinatal periods and appear to be in good health. Their psychomotor growth is typical up to their first or second year of life, at which point brain functional regression starts. Clinical signs of the regression include the emergence of stereotyped hand movements, a loss of fine motor skills, gait apraxia, verbal and nonverbal communication deficits, and epileptic seizures.
Delayed presentation of traumatic hepatothorax: An anesthetic and surgical perspective

Published: March 2024

: Traumatic diaphragmatic hernia is an uncommon sequela of blunt and penetrating trauma. It is estimated that 0.8–1.6% of patients with blunt trauma develop diaphragmatic rupture. However, the diagnosis of this condition is often overlooked, with right-sided hernias missed more frequently than left-sided hernias. Early diagnosis and repair are essential to prevent future complications such as strangulation and ischemia of intra-abdominal organs, lung collapse, and cardiovascular demise.

: A 17-year-old male (180 cm; 86 kg) with no comorbidities presented to the emergency department (ED) following a high-velocity, unrestricted, rear-ended motor vehicle crash (MVC). The patient was intubated and hemodynamically stabilized in the ED, with planned surgical exploration of the abdomen. Six days following the accident, the patient was extubated; he became increasingly hypoxic and tachypneic over the next day. A CT of the chest and pelvis was ordered, confirming the diagnosis of a post-traumatic right-sided diaphragmatic hernia. An exploratory laparotomy was scheduled. Difficulties with ventilation were encountered due to suspected lung compression by the liver and movement of the endotracheal tube into the right main lung bronchus.

: Traumatic diaphragmatic hernia should be considered in all patients presenting with abdominal trauma and should be suspected if respiratory distress arises during the patient’s clinical course. The recommended anesthetic approach is rapid sequence intubation with a cardiovascular-stable agent like etomidate and gastric decompression. Difficulties with intubation and ventilation should be anticipated due to the presence of the visceral organs within the thoracic cavity.

Published: March 2024

Extrapulmonary tuberculosis is a very common cause of generalised lymphadenopathy especially in tuberculosis endemic regions like India. A 33-year-old lady who had been diagnosed with rheumatoid arthritis 5 years back and had received treatment with biologicals including adalimumab presented with a 3 week history of persistent fever associated with significant weight loss and abdominal fullness. Investigations pointed towards a picture of tubercular aetiology although, a definite microbiological diagnosis was not possible at this stage. Patient also had an underlying subacute thyroiditis with diffusely increased uptake in Tc99 scan. Considering the background risk factor of use of biologicals and typical clinical presentation resembling tuberculosis, a decision to start antitubercular therapy was taken. The fever resolved but it recurred after 2 weeks and then after an extensive workup, the diagnosis of coexistent IgG4-related disease along with microbiological diagnosis of tuberculosis was established. This case highlights the importance of an active search for coexistent pathologies in cases of lymphadenopathy with insufficient response to standard therapy.

ST-segment elevation in chronic bleeding post-curettage with COVID-19 antibodies: A case report
Authors: Wijaya WS  , Krisnawati Ika
Published: March 2024

Acute coronary syndrome has a variety of symptoms and remains poorly under diagnosed and under treatment in women, especially myocardial infarction or ischaemic with non-obstructive coronary arteries (INOCA) as the culprit. We present a case of an Indonesian adult female with hypoxemia and ST-elevation in post-curettage due to molar pregnancy and positive COVID-19 antibodies.

A 43-year-old Indonesian female was admitted due to confusion, dyspnoea, and chronic bleeding after the curettage. The electrocardiogram (ECG) showed ST-elevation in lead I and aVL. Her condition quickly stabilised after getting oxygen supplementation and nitro-glycerine with ST-elevation resolution and no neurological impairments. Due to COVID-19 pandemic, she was checked for a swab test which showed negative but positive on her antibodies test. Chest X-ray was normal, but the echocardiography showed mild left atrial dilatation. After standard atherosclerosis treatment and anticoagulant, her condition improved, despite recurring vaginal bleeding. During her outpatient follow-ups, suspected intrauterine leiomyoma was diagnosed by ultrasound.

Cytokines and inflammatory responses from prolonged bleeding, hormones, metabolic disturbances, and post-COVID-19 infection have the potential to provoke INOCA. Considering the complexity of our case, contributing factors to INOCA must be addressed to optimise the strategy. Further, imaging tests should be done to confirm the diagnosis.

Telah dilakukan penelitian mengenai penggunaan biomasa jamur Pleurotus ostreatus dalam penyerapan logam krom dari larutan limbah cair penyamakan kulit melalui proses biosorpsi. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan biomassa yang berbeda-beda terhadap kapasitas biosorpsi logam krom oleh jamur Pleurotus ostreatus pada limbah cair penyamakan kulit. Parameter yang diukur yaitu banyaknya serapan ion logam (q) untuk tiap gram biomassa yang digunakan. Enam variasi biomassa kering dari jamur Pleurotus ostreatus yaitu (0,04) g; (0,08) g; (0,12) g; (0,16) g; (0,20) g; (0,24) g dalam bentuk serbuk dicampurkan kedalam 0,25 L larutan limbah penyamakan kulit. Untuk pH larutan diatur hingga pH 5 dan waktu kontak penelitian yang digunakan adalah 80 menit berdasarkan hasil pra-penelitian. Konsentrasi larutan krom sebelum dan setelah perlakuan ditentukan dengan metoda AAS (Atomic Absorption Spectrometry). Konsentrasi logam krom sebelum perlakuan adalah 297,5 mg/L dan setelah proses pengontakan dengan biomassa jamur Pleurotus ostreatus kadar logam krom dalam larutan limbah dapat terserap hingga kisaran 73%- 80%. Serapan ion logam tertinggi terjadi pada biomassa perlakuan 0,04 gram yaitu sebesar 148,83 ± 2,58 mg/g dan terendah pada biomassa perlakuan 0,24 gram yaitu sebesar 22,75 ± 0,62 mg/g. Kapasitas biosorpsi maksimum dari jamur tiram putih (Pleurotus ostreatus) terjadi pada konsentrasi biomassa yang rendah dan mengalami penurunan seiring dengan peningkatan kosentrasi biomassa yang digunakan.
BIODEGRADASI POLI(HIDROKSIBUTIRAT co CAPROLAKTON) DENGAN MENGGUNAKAN LUMPUR AKTIF
Authors: Anwar Budiman
Published: March 2024

Penelitian mengenai plastik yang terbiodegradasi di alam diperlukan dalam upaya penanganan masalah limbah plastik berbasis petrokimia. Lumpur aktif merupakan suatu materi yang mengandung berbagai jenis mikroorganisme dan secara umum digunakan untuk membiodegradasi bahan-bahan polimer. Bahan yang dibiodegradasi ialah homopolimer PHB dan PCL serta kopolimernya, semuanya merupakan hasil sintesis secara kimia melalui pembukaan cincin senyawa lakton. Polimer dibuat berbentuk film dan dibiodegradasi oleh lumpur aktif dalam media padat pada suhu 37C dengan variasi waktu 2, 7, 14, 21 dan 28 hari. Hasil penentuan %-kehilangan berat menunjukkan bahwa semua polimer terbiodegradasi meskipun dengan laju biodegradasi yang berbeda. Hasil identifikasi dengan XRD menunjukkan bahwa laju biodegradasi dipengaruhi oleh derajat kristalinitas polimer. Makin tinggi derajat kristalinitas, laju reaksi makin lambat. Adanya monomer CL dalam PHB meningkatkan kemampuan akses mikroorganisme terhadap polimer, sehingga laju biodegradasi kopolimer lebih cepat daripada homopolimernya. Spektrum FTIR sebelum dan sesudah inkubasi tidak menunjukkan perubahan puncak serapan khas. Dengan demikian biodegradasi berlangsung melalui reaksi hidrolisis ikatan ester pada rantai polimer.

ABSTRAKPemahaman konseptual sangat penting bagi seorang calon guru karena pemahaman konseptual merupakan se-kumpulan ukuran kualitas dan kuantitas pada konsep-konsep matematika yang direpresentasikan dalam ben-tuk jaringan pengetahuan tertentu dan keterampilan yang terdapat didalamnya. Unsur-unsur dari jaringan ini dapat berupa konsep, aturan (algoritma, prosedur, dan lain sebagainya), dan pemecahan masalah. Penelitian ini berusaha mencari solusi alternatif dengan memusatkan perhatian pada kondisi pembelajaran matematika yang selama ini berlangsung di ruang perkuliahan, melalui penelitian eksperimentasi pembelajaran dengan pendekatan investigasi matematika. Subyek penelitian ini adalah 111 mahasiswa PGSD di salah satu perguruan tinggi negeri di wilayah Sulawesi Tenggara. Hasil penelitian menunjukkan bahwa terdapat perbe-daan pemahaman konseptual yang signifikan pada mahasiswa yang memperoleh pembelajaran dengan pen-dekatan investigasi matematika dibandingkan dengan pendekatan eskpositori (p= 0,000; p 0,005) dan tidak terdapat pengaruh interaksi antara kemampuan awal matematika dan pendekatan pembelajaran terhadap pe-ningkatan kemampuan pemahaman konseptual mahasiswa. Oleh karena itu, pendekatan investigasi dapat di-berlakukan pada seluruh level kemampuan awal karena telah terbukti dapat meningkatkan pemahaman kon-septual.ABSTRACTConceptual understanding is very important for pre-service teacher because conceptual understanding is a set of mathematical concepts’ quantity and quality measure that are represented in the form of knowledge and skills network contained therein. The elements of this network can be concepts, rules (algorithms, procedures, etc.), and problem-solving. This study attempted to found alternative solution focusing on mathematics learning conditions in the classroom, through learning experimentation study using mathematical investi-gation approach. Subjects were 111 PGSD pre-service teachers in one of state university in Southeast Sulawesi. Results suggested that there was a significant conceptual understanding difference between pre-service teacher receiving mathematics investigation approach compared to those receiving expository approach (p=0,000; p 0,005) and there was no interaction between prior knowledge with learning approach to pre-service teachers’ conceptual understanding increment. Therefore, investigation approach can be imple-mented for all prior knowledge level because this approach proved to improve conceptual understanding.

Students’ prior knowledge effect on these cooperative learning implementation results was addressed.
PENERAPAN PENDEKATAN CONCRETE-REPRESENTATIONAL-ABSTRACT (CRA) BERBASIS INTUISI UNTUK MENINGKATKAN KEMAMPUAN ANALOGI MATEMATIS SISWA SMP
Authors: Azmi Memen Permata
Published: March 2024

ABSTRAKPada penelitian ini pendekatan Concrete-Representational-Abstract (CRA) berbasis intuisi diterapkan untuk menyelidiki kemampuan analogi matematis siswa. Sampel penelitian adalah 66 siswa sekolah menengah pertama di Kabupaten Kampar-Riau. Siswa dibagi menjadi kelas CRA berbasis intuisi atau kelas Pembelajaran Kon-vensional (CL). Siswa juga dikelompokkan berdasarkan kemampuan awal matematis atau Early Mathematical Ability (EMA) menjadi kelompok tinggi, sedang, dan rendah. Instrumen penelitian adalah tes harian dan tes kemampuan analogi matematis. Hasil menunjukkan bahwa kemampuan analogi siswa yang menggunakan pendekatan CRA berbasis intuisi lebih baik dibandingkan siswa yang menggunakan CL. Hasil ini berlaku bagi kelompok EMA sedang dan rendah, tetapi untuk EMA tinggi, peningkatan pada siswa yang menggunakan CRA berbasis intuisi justru tidak lebih baik. Oleh karena itu, dapat disimpulkan bahwa meskipun CRA berbasis intuisi mempengaruhi kemampuan analogi matematis, efek yang dihasilkan mungkin berbeda berdasarkan tingkat EMA.ABSTRACTIn this study, intuition based Concrete-Representational-Abstract (CRA) approach was implemented to investigate students’ mathematical analogy ability. Samples were 66 junior high school students in Kampar Regency-Riau, in which they were divided into intuition based-CRA class or Conventional Learning (CL) class. Students were also classified based on their early Mathematical Ability (EMA) into high, medium, and low EMA level. The instruments of this study were daily test and mathematical analogy ability test. Result suggested that mathematical analogy ability of students who used intuition based-CRA approach was better than students who used CL. This result applied to low and medium EMA level but for high EMA level, the enhancement in students who used intuition based-CRA was not better. Therefore, it can be concluded that even though intuition based-CRA affected mathematical analogy ability, this effect might vary among different EMA level.

Authors: Jupri Al , Syaodih Ernawulan
Published: March 2024

This study investigated primary education master program students’ problem solving strategies and their for-mal and informal thinking ability when dealing with geometry problems that require the use of algebra in its solution processes. In order to do so, an explorative study through individual written test, observation, and field notes, involving 47 primary education master program students was carried out. The perspective of Van Hiele theory on the development of geometric thought was used to interpret student formal and informal thinking strategy when dealing with geometry problems. The results showed that more than half of the stu-dents used informal rather than formal algebraic strategies in solving geometry problems; when students used algebraic strategies, their work were imperfect as they still made mistakes in applying the strategies. In the light of Van Hiele theory, it can be concluded that students’ level of thinking are still in between formal and informal thinking when dealing with geometry problems.ABSTRAKPenelitian ini menyelidiki strategi pemecahan masalah mahasiswa program magister pendidikan dasar serta ke-mampuan berpikir formal dan informal mereka ketika menyelesaikan soal geometri yang memerlukan peng-gunaan aljabar dalam proses penyelesaiannya. Untuk mencapai tujuan ini, studi eksploratif melalui tes indi-vidu tertulis, observasi dan catatan lapangan dilakukan dengan melibatkan 47 mahasiswa program magister pendidikan dasar. Teori Van Hiele digunakan untuk menginterpretasi kemampuan berpikir formal dan infor-mal mahasiswa dalam menyelesaikan soal-soal geometri. Hasil penelitian menunjukkan bahwa lebih dari sepa-ruh mahasiswa menggunakan strategi-strategi informal ketimbang strategi-strategi aljabar formal dalam proses penyelesaian soal-soal geometri; ketika mahasiswa menggunakan strategi-strategi aljabar, proses penyelesaian yang mereka lakukan tidak sempurna dan masih melakukan kekeliruan-kekeliruan dalam menerapkan strategi tersebut. Berdasarkan tinjauan teori Van Hiele, dapat disimpulkan bahwa kemampuan berpikir mahasiswa ma-sih berada pada kemampuan antara formal dan informal ketika menyelesaikan soal-soal geometri.How to cite: Jupri, A., Syaodih, E.

In learning biology, teachers often use visual media, such as diagrams, to help students understand the concept. This study was focused on how students’ mental representation (MR) when they read biological diagrams, either representation convention diagram or spatial isomorphism diagram. The student’s MR was analyzed using a worksheet modified from an MR measurement model of CNET protocol. This model involves three main components of the MR’s working memory: causal network, probability parameter, and utility parameter. Ninety 11th grade students of a senior high school in Bandung voluntarily involved in this study. Only 59 students, however, performed the worksheet completely. The result revealed that each student gave a different pattern of MR either when he/she read convention or spatial diagram. These differences could be traced since the student decides and orders the information elements and makes a causal network. Based on this result, we suggest that this method of MR analysis using a worksheet can be used to understand how student’s working memory works on MR building when they read a diagram. Understanding how the student can construct MR is a necessary platform to provide appropriate visual media that will help the student improve their learning achievement.

Published: March 2024

The connection between academic self-concept and mathematics achievement has been widely studied, but the consideration from students’ internal process when solving a mathematical test is surprisingly rare. Students’ mathematical problem-solving ability was evaluated from their ability to solve trigonometry problems, while students’ academic self-concept was obtained from a questionnaire. The result indicated that students’ academic self-concept is linearly connected with their ability to solve mathematical problems. Students with high academic self-concept also possess an excellent ability to solve mathematical test problems and vice versa.

Authors: Nurdin Enjang Ali
Published: March 2024

Discovery learning is arguably the most debated learning approach because even after more than 58 years since Brunner suggested it in 1961, it continued to be a center of heated debate. The main concern for numerous educational experts was the degree of teacher involvement in discovery learning. One of the discovery learning variants which addressed this issue is discovery-inquiry learning, a learning model currently endorsed by the Indonesian Government to be implemented in the classroom. This study explored the potency and caveats of discovery-inquiry learning model and discussed improvement suggestions when implementing the model.

Students’ perception of assessments can serve as a guiding light for improving overall educational practices. A questionnaire was collected from 80 engineering student to discover students' perceptions of different types of assessment and their overall perceptions of various type of assessments advantages in enhancing learning experiences. The majority of students strongly agreed that quiz and case study was beneficial and helpful for enhancing learning experience in engineering courses. On the contrary, project presentation, journal review, essay, interview, and demonstration was seemed unhelpful for students to enhance their learning experience. In terms of enjoyment, a discrepancy was found for what engineering students’ perceived as important assessment tools for learning and what they actually enjoy doing.
