Authors: Kalu Cosmus Mwachiru , Rugami James Maina
Published: May 2021

This study sought to examine stakeholder involvement and implementation of infrastructure projects in Kenya Ports Authority. The specific objectives were to examine the influence of stakeholder empowerment, stakeholder communication and stakeholder grievance management on the implementation of infrastructure projects in Kenya Ports Authority. Implementation of projects at KPA has had challenges such as unmet timelines, cost overruns, scope variations and compensation demand by the local community. Theories that anchored this study are stakeholder theory, empowerment theory, game theory and communication theory. The study employed descriptive survey research design. The cadres of target population included persons in port electrical engineering, projects development and management, civil engineering, container operations, and conventional cargo operations departments totalling to 3,336 persons. The study used stratified sampling approach and the sample size was 358 persons. A structured questionnaire, containing close-ended questions was employed as the primary tool for data collection. Validity of the instruments was ensured using content validity, construct validity and face validity. Cronbach alpha coefficient test was used to test the reliability of the instrument. Microsoft Excel software and Statistical Package for Social Scientists software were used for data analysis. Multiple Regression analysis was used to determine the relationships and significance between independent and dependent variables. Tables and charts were used in the presentation of findings. The study established that stakeholder empowerment, communication and grievance management had a positive and significant effect on project implementation. This study concluded that stakeholder empowerment increases the ability and confidence of stakeholders to make choices and decisions. Effective communication helps the organization to build positive relationships with the project stakeholders whereas management of grievances provide a way to reduce projects’ risk, provide an effective avenue for expressing concerns and promote a mutually constructive relationship towards implementation of projects. The study recommended that stakeholders be empowered by allowing them to participate in decision making. Giving them more control over what happens in their work environment through control over work tasks, work pace and freedom from supervision. Project managers should establish regular communication with stakeholders and create a positive understanding to help build effective long-term relationships with key project stakeholders. The organization should adopt a structured mechanism for management of grievances that will be known to all employees.

MORBIDITY AND MORTALITY OF EXTREMELY LOW BIRTH WEIGHT BABIES IN A TERTIARY CARE CENTRE IN EASTERN INDIA
Authors: Ghose Neena , Basu Sumita
Published: May 2021

Background: Being born preterm increases the risk of both morbidity and mortality but with improved care the chances of survival is increasing.
The age of viability was earlier dened at 28weeks but in the best of centres it has now come down to 25weeks. Extremely low birth weight
(ELBW) babies who weigh less than 1000gms are particularly at risk of dying with the overall mortality in this group ranging from 30% to 50 % in
the best of centres. This study was conducted to nd out the immediate outcome of extremely low birth weight babies born in a tertiary care centre,
of a resource poor country like India.
Objective:To evaluate the immediate morbidity and mortality of Extremely Low Birth Weight Babies in the NICU setup of a tertiary care hospital.
Study Design:Retrospective Observational Cohort Study
Place of Study: Department of Paediatrics, Ramakrishna Mission Seva Pratishthan, Vivekananda Institute of Medical Sciences, Kolkata, India
Period of Study:January 2018 to December 2020
Methods: The study was a retrospective analysis of data of babies born with a birth weight of less than 1000gms and admitted to the Neonatal
Intensive care unit of Ramakrishna Mission Seva Pratishthan. The maternal demographic prole and delivery outcome were recorded along with
the neonatal morbidity and mortality in a predesigned proforma. These data were then pooled and analysed.
Results: The total number of ELBW babies born during this period was 31 out of whom 15 succumbed(48%). The studies in the developed world
too shows the mortality in this group to range between 30 to 50 %. Most of the deaths occurred in the rst few days of life due to birth asphyxia. The
commonest morbidity was Respiratory Distress Syndrome (RDS) (71%), followed by sepsis (64.5%), anemia (54.8%) and hyperbilirubinemia
(51.6%). Necrotising Enterocolitis (NEC) was found in 9.7% of babies. 16 babies (52%) survived and went home in a stable condition. Retinopathy
Of Prematurity (ROP) was detected in 11 of these babies for whom laser therapy was done with the advise for follow up.
Conclusion: This study shows that in a resource poor country like India too, the percentage of babies who can be salvaged amongst the extremely
low birth weight babies, matches with those in the developed countries, though a question remains about their long term morbidity

The surgical management of benign gastroduodenal perforation
Authors: Elroy Weledji
Published: May 2021

Gastric perforations may be spontaneous or traumatic and most of the spontaneous perforation is due to peptic ulcer disease. Improved medical management of peptic ulceration has reduced the incidence of perforation, but still remains a common cause of peritonitis. The management of perforated peptic ulcer disease is still a subject of debate. The majority of perforated peptic ulcers are caused by Helicobacter pylori, so apart from simple closure, definitive surgery is not usually required. Perforated peptic ulcer is an indication for operation in nearly all cases except when the patient is unfit for surgery. However, with the current advances in anaesthetic approach and with the high incidence of intra-abdominal abscesses and sepsis, non-operative management has largely been abandoned.

Published: May 2021

Background: The aim of this study is to describe the diagnostic evaluation and treatment in patients with complicated paraesophageal hernia (PEH) and distal gastrointestinal (GI) obstruction. Methods: Three cases with known PEH in the Department of Surgery of the General Hospital of Nea Ionia ‘’Constantopoulion-Patission’’, I woman 78 yrs, II man 88 and III man 78, underwent emergent open surgery for complicated PEH and GI obstruction. Cardiorespiratory distress in all and sepsis in I, were encountered. Case I had coexistent incarcerated abdominal hernia, II had a prepyloric lesion revealed by gastroscopy and III chronic constipation. X-rays and CT scan helped diagnosis. Operative findings: In case I, we found viable incarcerated bowel, gastric fundus and body strangulated in mediastinum, fundus ruptured, and antrum ischemic; total gastrectomy with esophageal and duodenal stapling were performed. In case II, the stomach with an obstructive prepyloric lesion was volvulized in mediastinum; distal gastrectomy, gastrojejunostomy, cruroraphy and fundopexy were performed. In case III, strangulation of the dolichosigmoid was the prominent feature, moreover, incarceration of gastric fundus and transverse colon in PEH sac were also found; reduction of PEH contents, limited resection of thick congenital bands, extended left colectomy, cruroraphy, fundopexy and caecopexy were performed. Results: Case I and II were transferred intubated to ICU. Case I was never stabilized, died after 50 hours; histology confirmed gastric necrosis. Case II was extubated on day 4, discharged on day 28; histology revealed antral ischemia and prepyloric pT2 adenocarcinoma. Case III had uneventful outcome; histology revealed dolichosigmoid ischemia. Follow-up of cases II and III (32 and 30 months respectively) has been uneventful. Conclusion: Obstructive conditions distal to large PEHs may lead to acute complications in hernia contents and emergent surgery is challenging. Obstructive conditions distal to large PEHs may lead to acute complications in hernia contents and emergent surgery is challenging.

Published: May 2021

Laparoscopic adjustable gastric banding (LAGB) is a popular bariatric surgical procedure. The introduction of laparoscopy has increased the use of this procedure, making it the most commonly performed bariatric surgery. Patients undergoing LAGB have achieved satisfactory results in terms of weight loss, a reduction in co-morbidities, and improved quality of life. Nonetheless, complications with LAGB are well documented and include migration, erosion, prolapse, infection, pouch dilation, gastric perforation, and most commonly, lack of weight loss following the failure of the procedure. This case report presents a patient with slippage and pouch dilation, erosion of the stomach, and port site problems, including infection, occurring 28 years after LAGB.

Legenda Ratu Kidul, Merapi, Krapyak
Authors: Murnianto Gatut
Published: May 2021

Legenda Ratu Kidul - Tugu - Merapi - Krapyak menggambarkan alam pikir orang Jawa yang sederhana. Menurut alam pikir orang Jawa, realitas tidak dapat dibagi dalam berbagai bidang yang terpisah-pisah dan tanpa hubungan satu kesatuan yang menyeluruh. Dunia, masyarakat dan alam adikodrati (supranatural) bagai orang Jawa merupakan satu kesatuan pengalaman. Jadi masing-masing tidak berdiri sendiri. Dalam alam pikir sederhana, alam (semesta) itu dianggap mempunyai kekuatan adikodrati atau supranatural. Dengan kekuatan ini alam (semesta) dianggap keramat atau sakral. Sikap manusia terhadap alam adikodrati ini diwujudkan dengan nilai yang praktis untuk mencapai suatu keadaan yang psikis tertentu, yaitu ketenangan, ketentraman, dan keseimbangan batin, ini akan membawa pada hidup sejahtera bagi anggota masyarakat. Ratu Kidul - Merapi adalah wujud personifikasi dari supranatural. Ratu Kidul adalah sosok yang diakui sebagai penguasa Laut Kidul yang diyakini oleh penduduk memiliki kekuatan supranatural. Merapi atau Gunung Merapi dalam Kosmologi Jawa dikatakan sebagai wujud Bathara Siwa yakni alam semesta, yang banyak menyimpan kekuatan supranatural dan bila lebih diperluas adalah manusia, dalam hal ini Poerbatjaraka (1952) menyebutkan : Bathara Siwa = Suwung; Sipatipun ingkang alus, inggih puniko aluso dhonyo; Yen karingkes, dados aluse meru; Yen karingkes malih, dados alusing manungso; (Bathara Siwa = Kosong = Alam semesta sifatnya yang halus dunia apabila diringkas adalah GununBila diringkas lagi adalah manusia). Dalam konsep Hindu, Gunung atau Meru itu tempat para Dewa. Karena itu Gunung atau Meru ini menyimpan kekuatan supranatural. Tugu yang lalu dikatakan golong-gilig adalah wujud kemanunggaling kawula dengan Gusti atau Penguasa (Pemimpin Negara). Tugu ini juga merupakan gambaran kedekatan manusia dengan Tuhan. Karena itu Sri Sultan sebagai pengayom kawula meletakkan tugu yang lurus dengan singgasana tempat duduk Sri Sultan. Krapyak dibuat sebagai lambang awal dari hidup manusia, sangkaning dumadi. Jadi bila diurutkan letak Krapyak - Tugu - Merapi - sampai Laut Kidul, menggambarkan tentang : Sangkan Paraning Dumadi. "Laut Kidul merupakan sumber kekuatan manusia. Ingat cerita "Dewa Ruci" ini satu hal yang menarik bila dikaji lebih mendalam. Dari ini Yogyakarta membuktikan bahwa tidak saja kaya obyek wisata secara fisik tetapi juga isi dari obyek wisata itu.

Published: May 2021

Introduction: Undescended testis (UDT) or cryptorchidism is a common childhood condition in which a boy is born without having one or both testes in their scrotum. It is a very frequent clinical finding in boys, with a prevalence of about 2-4%. The inguinoscrotal phase of testicular descent normally takes place in the last trimester of pregnancy. The regulation of prenatal testicular descent in humans is not fully understood, but numerous genetic and endocrinal factors are thought to have been involved. Preterm boys have been described to have a higher rate of UDT. The classification of UDT is performed according to palpable or nonpalpable testis. If the testis is located inside the normal path of descent, the testis is called ’intra-abdominal’, for those located in the abdomen is called ’intracanalicular’, for those located between the internal and external rings or ’suprascrotal’, for those located between the entrance of the scrotum and the external ring. This study was conducted to determine the frequency of anatomical location of undescended testis in pediatric patients undergoing orchidopexy as well as to compare the mean size of undescended testis at different anatomical location in pediatric patients undergoing orchidopexy as a secondary objective.

Methods: It’s a cross sectional study of 94 patients with total 110 testes as per inclusion criteria. Study was performed at pediatric surgery department of Liaquat National university hospital Karachi, Pakistan for a duration of eight months. Orchidopexy was performed under general anesthesia as a surgical day care procedure. At orchiopexy, the outcome variables i.e. location and size of the testis was noted. The size of the testis was measured in anteroposterior and mediolateral dimensions vernier caliper, graduated in mm. The size of testis was calculated by modified Lambert’s formula (0.71xlengthxwidth2). All the collected data were entered into the proforma attached at the end.

Results: Mean±SD of age was 4.29±2.19 with C.I (3.38…….4.74) years. Mean±SD of size of testis was 425.68±244.43 with C.I. (375.89……..475.47) mm. In location of testis 4 (4.2%) was located at intra-abdominal, 15 (16%) at intracanalicular and 75 (79.8%) was located at distal to superficial ring. Mean size of testis in intra-abdominal location was 276.29±145.47, intra-canalicular 367.89±196.15, distal to superficial ring was 442.27±54.08 and non-significant P-value was found i.e. (p=0.264).

Conclusion: No significant difference was found between mean size of testis and location of undescended testis. The most common location was distal to superficial ring.

Published: May 2021

Cacao (Theobroma cacao L.) is known to have enormous potential advantages because they contain vitamins A1, B1, B2, C, D, and E as well as minerals such as iron, zinc, phosphorus, magnesium, and copper. In addition, chocolate is also known to be rich in active antioxidant ingredients such as phenolic compounds, prociandin, and flavonoids which can reduce the bad effects of antioxidants in the body. giving chocolate to experimental animals and consumption interventions in humans can prevent and overcome the problem of several diseases, one of which is diabetes mellitus. The purpose of this study was to see the effect of giving cocoa powder drink to the wet weight of the liver in rats with diabetes mellitus. The research design used was experimental research using a completely randomized design with a post-test only control group design. The experimental sample used fifteen male white rats (Rattus norvegicus) Sprague Dawley strain. The experimental mice were divided into 5 groups, namely the negative control group (K-), namely normal rats without any treatment, the positive group, namely the diabetes mellitus (K +) group; treatment group 1 (KP1), treatment group 2 (KP2), treatment group 3 (KP3), namely the diabetes mellitus group of rats that were given the treatment of chocolate drink with a concentration of cocoa powder drink doses of 2%, 4% and 6%. Data analysis was performed using the One Way ANOVA test. Results: The results showed that the organ weight in the group K- = 10.46 ± 0.44; K + = 11.49 ± 0.39; KP1 = 9.95 ± 0.60; KP2 = 11.30 ± 0.60; KP3 = 11.09± 0.90. Statistical analysis showed that there was no significant difference for each treatment with a value of p = 0.077. The conclusions in the study regarding the effect of giving chocolate drink on the wet weight of the liver in rats with diabetes mellitus showed that giving cocoa powder with a concentration of 2%, 4% and 6% was not able to significantly affect the wet weight of the liver.
