Climate Change Impacts and Forecasts of Oil Palm Leaf Miner Populations
Authors: Thomas Idemudia Aneni , Victor Chuks Adaigbe
Published: March 2021

Agricultural production is very sensitive to climate change, and it suffers from periodic outbreaks of insect pests which cause considerable losses especially in the humid and sub-humid tropics which severely constrain the productivity potential of global agriculture under changing climate conditions. The oil palm leaf miner is a major pest of the oil palm. Mathematical relationships between the leaf miner insect stages and weather factors were developed for pest predictions and forecasting. Decadal variation in air temperature was characterized by wide differences between 1961 – 1970 and 2001 – 2010. The assessment of the sensitivity of leaf miner to variability in weather and climate conditions is important in view of evidence that show expansion of pest ranges as a result of climate variability impacts. The study has established an upward increase in temperature, attributed to climate change, with a concomitant increase in leaf miner abundance between 1980 and 2010. Larvae showed an increasing trend for the observed period. When this observation was correlated with the weather (temperature, rainfall, and relative humidity) during these periods, it could be inferred that there was proliferation as a result of weather changes. This was different from the decreasing trend observed during the 1976 – 1980 period. Pupae showed a decreasing trend for the observed period. Adults showed an increasing trend for the observed period. It could be inferred that adults were proliferating due to temperature increases and rainfall decreases. An incremental increase in temperature could help explain fluctuations in insect pest populations within and between years. Thus climatic conditions greatly influenced seasonal leaf miner populations. The climate forecast up to 2050 indicates an upward trend in temperature and a downward trend in rainfall and relative humidity. This followed the climate trend between 1961 and 2010. This study contributes to the understanding of the insect pest-weather relationship in broad agricultural and food security terms. A major advantage is the potential for limiting the spread of outbreaks through timely control of early pest infestations.

Published: March 2021

The present investigation aimed at comparing meat qualities of broiler chickens reared on deep litter as affected by skip-a-day feed restriction and strain. A total number of two hundred and eighty-eight (288) unsexed day-old broilers comprising of 96 chicks each of Arbor acre, Marshall and Hubbard strains of broiler chickens raised on intensive housing systems were used to evaluate the organoleptic attributes. The chicks were allotted randomly to 12 pens per strain. The birds were distributed into four treatments with three replicates per treatment. An organoleptic test was carried out using the breast muscle at the 8th week. The cuts were salted and kept inside labeled polythene bags and steamed to the temperature of 72ᶿC. A total of ten trained individuals aged between 20 and 30 years (males and females) were employed to assess the coded meat samples. Equal bite size from each treatment was coded, replicated thrice, and served for evaluation by the trainees. Analyzed results revealed that the organoleptic parameters such as Aroma, flavor, tenderness, juiciness, texture, and overall acceptability were not significantly affected by both the different feeding regimes and strains of broiler chickens.

LESSONS DERIVING FROM AN EASY LAPAROSCOPIC CHOLECYSTECTOMY
Authors: Andronic Octavian
Published: March 2021

Gallstone is a very frequent condition, therefore laparoscopic cholecystectomy - the gold standard in the treatment of the above mentioned pathology - is the most frequent surgical intervention performed in the surgery departments in the country and abroad. At the same time, it is the laparoscopic surgery with the highest number of intraoperative incidents and accidents. Thus, in a surgical environment dominated by the stress of injuring the main bile duct, extracting the piece and sending it for the anatomical pathology examination remains on a secondary level. This is why we would like to discuss a problem related to laparoscopic cholecystectomy which is less approached in the specialty literature. Patient B, admitted to the General Surgery and Emergency Clinic III of the University Emergency Hospital of Bucharest (UESB) – medical chart (M.C.), aged 66 with a surgical history – a simple, uncomplicated laparoscopic cholecystectomy, undergone ​​two years before, with a good postoperative evolution – came to the emergency room with diffuse abdominal pain, more pronounced on the right flank. The clinical, biological and imaging evaluation performed did not reveal any pathological aspects, except for the abdominal-pelvic CT scan with a contrast agent which revealed an expansive process in the right hypochondrium lining the costal side of the liver segment VI. The tumour was surgicaly removed; the extemporaneous histopathological examination was inconclusive about the origin of the tumoral formation (adenocarcinoma of the digestive tract ). The key to the diagnosis was obtained in an administrative manner because, when the discharge letter delivered at the time of the cholecystectomy was reviewed, the absence of the result of the anatomical pathology examination of the cholecystectomy piece was noticed. The respective clinic was contacted and the result of the anatomical pathology examination was obtained, i.e. adenocarcinoma of the gallbladder. After 3 months from the surgery the patient returned with a left breast tumor with the HP diagnosis of invasive ductal carcinoma and a total Madden mastectomy wa performed. After 5 more months, surgery was necessary again for a parietal epigastic tumor - with the  anatomical pathology result of  cholangiocarcinoma. The author reports the case because he believes that this is further proof of the necessity of sending any cholecystectomy piece, and broadly speaking, any excised  piece, for the HP examination. Moreover the patient's attention should be drawn to the necessity of returning to the clinic to take the anatomical pathology result because this result may require the reconsideration of therapeutic conduct.

Neovascular glaucoma (NVG) is considered to be one of the rarest and most complex types of ophthalmologic diseases known up to the present moment, and is mainly caused by the obstruction of the iridocorneal angle through a neovascular membrane. We present the case of the patient MC, aged 46, who came to the Ophthalmologic emergency room of the University Emergency Hospital of Bucharest (SUUB), complaining of red, painful left eye (OS) as well as a severe decrease of the visual acuity (VA) in the left eye (OS).In the patient’s medical record it is noted a surgical procedure for cataract which he underwent in another clinic 2 months prior to the current presentation.Systemically hypotensor treatment was instituted, topically an intravitrous Bevacizumab injection followed by scleral flap trabeculectomy in the left eye (OS). As a result, the evolution was favorable including a decrease in the intraocular pressure. The patient is discharged, with immunosuppressive therapy for serpiginous choroiditis according to the rheumatologic findings (Cyclosporine).Serpiginous choroiditis is an inflammatory lesion of unknown etiology part of the White Dot Syndromes (WDS), probably the most severe form of them. It is a very rare condition, and in the cases of patients with serpiginous choroiditis the frequency of the choroidal neovascularisation is reduced and the neovascular glaucoma is exceptional. The surgical treatment of the neovascular glaucoma has poorer long-term prognosis compared to other forms of glaucoma.The peculiarity of the case comes both from the rare cause of the neovascular glaucoma, specifically the serpiginous choroiditis, also a rare autoimmune disorder, and the need for clinical cooperation between the ophthalmologist and immunologist or a rheumatologist in order to establish the adequate treatment and follow-up.
A CASE OF BOCHDALECK’S HERNIA AND A GIANT OVARIAN CYST IN A GERIATRIC PATIENT
Authors: Topor Andreea Teodora
Published: March 2021

Some authors define a giant ovarian cyst as having more than a 10 cm diameter . Huge cysts are usually benign or have a low-degree of malignancy . Laparoscopy is considered the gold standard approach to manage benign ovarian cysts but a major factor that will make the surgeon decide to perform or not perform a laparotomy is the size of the ovarian mass. We describe the case of an 86-year-old female patient diagnosed and treated for a giant ovarian cyst. The patient presented with complaints of recently aggravated pain in the left hypochondrium. The main symptom was a giant pelvic and abdominal mass that occupied all the quadrants. The CT scan identified the giant tumor as an ovarian cyst and also revealed a Bochdaleck hernia. Other investigations revealed: arterial hypertension, right bundle branch block, and chronic cardiac failure. The surgical treatment of choice was minimal laparotomy followed by suction of the content of the cyst, excision of the cyst’s wall and left adnexectomy. Despite the advanced anesthesiological risks, the patient developed no postoperative complications. Patients can be operated on successfully even in old age and in complicated cases with good perioperative anaesthetic evaluation and careful election of the surgical technique.

Published: March 2021

The most frequent type of entrapment neuropathy is the carpal tunnel syndrome, represented by a constellation of signs and symptoms in which no test absolutely confirms the diagnosis. The bifid median nerve is an anatomic variation that can be associated with this syndrome and the surgeon must be aware of this condition preoperatively in order to plan correctly the surgical approach. Ultrasonography and magnetic resonance imaging can be successfully used for the detection of the anatomic variation of the median nerve, for the complete evaluation of the carpal tunnel soft tissue and its anatomic structures in order to obtain better results. We present two cases of unilateral carpal tunnel syndrome with bifid median nerve diagnosed preoperatively by means of ultrasonography and the good outcome after the open decompression procedure. The existence of anatomic variation of the median nerve along with other possible pathologies in the carpal tunnel determine us to select the open procedure despite the existence of the endoscopic approach in order to provide better visualization in the surgical field and correct identification of the anatomic structures.

Published: March 2021

Uterine congenital malformations of the uterus appear due to the fusion and/or resorbtion defects of the Mullerian paramesonephric ducts, throughout the organogenesis. One of the relative frequent malformations is the double uterus, in which there are two uterine cavities and two cervices which enter the vagina (with or without a longitudinal median septum). The overall frequency of uterine malformations is difficult to appreciate because of the asymptomatic evolution in most cases. In 25% of the cases, congenital malformations of the uterus are accompanied by abnormalities of the excretory system. We present the case of a 27-year-old patient taken out to 7 weeks of amenorrhea. Transvaginal ultrasound confirmed the diagnosis of double uterus with gestational bag in the right uterine cavity. The renal ultrasound performed confirmed the caliceal malformation. Labor triggers in week 35, complicated with acute fetal distress, thus an emergency caesarean section was decided. A segmental-arched hysterotomy is performed along with a breech-presentation delivery; the fetus masculine with G=2600g, L=48cm, APGAR 6. The evolution of the patient and of the fetus was favorable, they were discharged after 14 days postpartum. This case required a complex approach, the evaluation protocol of the patient being an individualized one, in order to minimize the risks.

Acute appendicitis is the most common abdominal non-obstetrical emergency in pregnant women;its management however is supported by a low level of evidence. The main objective of this studywas to evaluate the clinical management of pregnant women with acute appendicitis.We havereviewed the hospital database selecting the pregnant women with acute appendicitis managed inthe last 24 months. 8 appendectomies were performed in pregnant women. Mean age was 27.2±6.1years. All patients had a history of right lower abdominal pain of 36 hours or less. Generalanesthesia was used in 12.5% of cases and spinal anesthesia in the remaining of cases. In all casesappendectomy was performed through a McBurney’s incision with a mean operating time of 36.25minutes. There was no maternal or fetal mortality.The diagnosis of acute appendicitis ischallenging in pregnant women. A prompt, but a non-negative appendectomy should always beaimed, and no unecessary risks should be taken.

Myomas or fibroids represent the most frequent type of genital benign tumor in women. Abdominalmyomectomy was developed in the early 1900s as a conservative treatment for women with uterinemyomas. A 29-year-old woman was admitted in our clinic for menomethrorragia and lowerabdominal pain. She had no obstetrical past regarding abortions or deliveries but she desired toobtain a pregnancy in the future. The clinical and ultrasound examination revealed an enlargeduterus of about 10/9 cm with a 8/7 cm fibroid involving the entire anterior wall. We decided toperform myomectomy. Laparotomy was the choice instead of laparoscopy, considering the size andlocalization of the myoma. We succeeded to remove the fibroid, control the bleeding and let theuterus in place. Postoperative the patient presented anemia with hemoglobin levels between 6-8g/dl due to heavy intraoperative blood loss. She received blood products to correct the anemia. Shewas discharged 5 days after the surgery and made a check visit one month later. She had nocomplaints and there was no pathology according to her physical examination. We report the caseof a young woman with uterine large intramyometrial fibroid. The challenge of this case was topreserve uterus and fertility after myomectomy in consideration of the heavy operative hemorrhage.

Acute appendicitis is a common surgical condition that requires prompt diagnosis. However adecision to operate based on the clinical suspicion alone can lead to removal of the normalappendix in 15-30% cases. Besides the modern imaging techniques, scoring systems, based onclinical signs and symptoms and routine laboratory assessments, have been used as a diagnosticaid. However, differences in sensitivities and specificities were observed if the scores were appliedto various populations and clinical settings. The purpose of this paper is to assess the validity of theOhmann score and the correlation of ultrasound in diagnosis of acute appendicitis. A total of 80patients were enrolled in this study, 52 male patients and 28 females patients suspected of acuteappendicitis that were admitted, investigated and treated. After detailed examination andinvestigations, the Ohmann score was applied to these patients. A cut off point of 9 was taken.Patients were divided into two groups, group I score of ≥ 9 and group 2 score of < 9. This studywas conducted at SDM College of Medical Sciences and Hospital Dharwad.Proportion of truepositive for score ≥ 9 is 86.9%, Proportion of true negatives for score <9 is 87.1%. Sensitivity andspecificity of this study being 96% and 66.7%, positive predictive value and negative predictivevalue being 82.8 % and 90.9% respectively. Diagnostic odds ratio being 48 and P value of <0.005.The high scores in Ohmann scoring system is dependable aid in the early diagnosis of acuteappendicitis. Combined with ultrasound, the Ohmann scoring system has high sensitivity andspecificity, in the prediction of acute appendicitis.

We present a case of severe hypertriglyceridemia-induced acute pancreatitis associated withdiabetic ketoacidosis, managed in the intensive care unit. The patient was a 39-year-old woman, with amedical history of Graves-Basedow disease, essential arterial hypertension and morbid obesity(body mass index=31). Firstly, we aggressively corrected hypovolemia and hemodynamicimbalances (administrating fluids and systemic anticoagulant) and then we focused on the infectionprevention and control of intra-abodminal pressure, for the latter outcome. We decided to start the firstsession of plasma exchange. The patient responded well to the treatment applied. Plasma-exchangewas very efficient, reducing TG levels by 60% after the first treatment and achieving a decrease of77.6% at the third plasmapheresis session. This case was safely and effectively managed withplasmapheresis (three sessions), antibiotics, multimodal analgesia (intravenous and thoracicepidural catheter), early jejunal nutrition and forced mobilization. The patient's evolution wassignificantly favorable, with a reduction of the peripancreatic necrosis on computer scan, at day 28and she was discharged with a normal value of TG and without pain or any clinical signs.

Osteosarcoma is the most common primary malignant bone tumor, with a higher prevalence among children and young adults. Its most frequent localization is in the distal femur, followed by the proximal humerus and the proximal femur. In this article, we will describe the case of a 25-year-old male patient who presented to our medical facility, accusing spontaneous pain and swelling, both originating from the left knee. The X-ray of the distal femur showed a heterogeneous mass around the left femoral metaphysis with massive periosteal reaction. The computerized tomography (CT) analysis revealed cortical destruction, with extra-compartmental localization. The patient has later undergone to an incisional biopsy. The histopathology report showed the presence of a chondroblastic osteosarcoma. According to the multidisciplinary diagnosis, the tumor was finallyclassified as type IIB on the Enneking classification. In such cases, the elective surgical procedure is reconstructive surgery, consisting of wide resection of the distal femur, followed by modular reconstruction. After the surgery, the patient’s condition improved significantly and the functional outcome of the reconstructed joint was also satisfying.

For Journal of Surgical Sciences, the year 2018 (its 5th year of existence) was one full of milestones and challenges which we managed to overcome successfully. At the end of the year, we have to draw a line and ask ourselves what we did good, what we did wrong, and especially what we can do better from now on. Among the negative things we had to overcome in 2018, the most difficult was the attack on the journal's website, which led to a long period of inactivity or limited activity. However, we have succeeded in transforming a very big problem, in a great deal of progress, by moving from a primitive and empirical workflow to a professional one that meets all the standards of current scientific publication. Thus, starting in 2019, the process of submission, peer-review, and communication between publishers, authors and reviewers will be accomplished through the OJS platform, that the new site relies on. In this way, we will be able to increase the quality and transparency of the peer-review process, which will move from an empirically to an authentic double-blind peer-review guaranteed by the platform's specifications.

Another aspect that we want to improve is plagiarism and redundancy. As early as 2017, we were able to scan all articles, using PlagScan, in order to detect plagiarism and dismiss articles that did not meet the mandatory criteria for research integrity. The experience of recent years determined us to believe that a percent of 5% for review articles and 2% for original papers is the maximum that we can accept under certain conditions.

Achieving the proposed threshold of 40 quality items per volume has sometimes made it difficult to launch a new number. Therefore, in order to maintain unnecessary delays and at the same time to maintain and even increase the rigor and requirements necessary to reach the current standards, there will no longer be a fixed predetermined number of articles per volume or per number.

Among the goals proposed for 2019, the most important is the indexation of the journal and the articles in new international databases, a process already started with the launch of the new site. In conclusion, we invite you to help increase the quality of the first European journal dedicated to students and young doctors, by sending high-quality articles and by actively participating in the peer-review process.
