Tidal influence on Fish Faunal Distribution and Species Diversity in Kakum Estuary, Ghana
Authors: Aggrey-Fynn Joseph , Siaw Gyimah David
Published: September 2024

Estuarine and coastal areas are complex and dynamic aquatic environments. In such an area, where river water mixes with seawater, a large number of physical and chemical processes take place, which may influence water quality thereby affecting the distribution and diversity of the biota. The study was conducted in the transition period of dry and wet conditions from February to May 2018. The influence of low and high tides on the hydrographic parameters such as salinity, dissolved oxygen, and water temperature in the three sampling stations was analyzed in relation to fish faunal distribution and species diversity of the estuary. The common fish species in the estuary were juveniles of Sarotherodon melanotheron and Mugil cephalus, Liza falcipinnis and the crab Callinectes amnicola. These species were encountered during both low and high tides in all sampling stations, which indicates their adaptation to a broader range of hydrographic conditions. The majority of species encountered were juveniles. Although most of the fish species were marine in origin, some including Tilapia zillii, Hemichromis fasciatus and Apolochelichthys spilauchen were freshwater in origin whilst, S. melanotheron is a resident fish species in the estuary. Length-frequency distribution and length-weight relationships of S. melanotheron, T. zillii, L. falcipinnis, Mugil cephalus, and Eucinosthomus melanopterus which were the five most dominant fish species during the period of study in Kakum estuary were analyzed. The modal sizes of the dominant fish species were mainly juveniles in the length-frequency distribution. The length-weight relationships of S. melanotheron, L. falcipinnis and M. cephalus showed allometric growth, whereas that of T. zillii and E. melanopterus showed isometric growth. The study, therefore, identified that Kakum estuary is a transitional zone for both marine and freshwater fish species using the estuarine ecosystem as nursery grounds. The presence of marine and freshwater-origin species, and resident species in the estuary further suggest that estuaries are highly dynamic, and slight changes in their environment can cause a great deal of harm to its fish biota.

This study is focused on examining the proximate body composition (water, fats, proteins, and ash) of Clarias batrachus, exposed to different concentrations of ammonia. Fish were kept in different groups with ammonia concentrations of 0 mg/L (T-0), 0.25mg/L (T-I), 0.5mg/L (T-II), 0.75mg/L (T-III), and 1mg/L (T-IV) for 3 months.  At the end of the trial, a total of 50 samples of C. batrachus (10 from each treatment group) were taken to analyze the body composition. Mean (±SE) values of water, ash, fat, and protein contents in % wet body weight of C. batrachus were found 77.07±0.80% to 82.23±0.55%, 2.98±0.03%to 3.34±0.17%, 3.90±0.19% to 4.58±0.30% and 10.53±0.40 to 15.36±0.56 in the different studied treatment groups. Water and protein contents were significantly (P<0.05) affected by the exposure of ammonia to C. batrachus. Significantly highest level of protein content was found in the fish group which was not treated with ammonia exposure (T-0). Whereas ash and fat contents showed no significant (P>0.05) difference between the ammonia-treated groups and the control group. Regression analysis showed a clear effect of fish size on water and protein contents in C. batrachus reared in different treatment groups. While ash was found correlated only in T-0 (p<0.001; r=0.939), and fat in T-0 (p<0.001; r=0.929) and T-III (p<0.05; r=0.636). However, the condition factor remained constant with the proximate composition of C. batrachus. This study would be helpful in the measurement of the body composition of fishes with the size of fishes affected by different concentrations of ammonia to analyze the nutritional value of C. batrachus.

Published: September 2024

Antimicrobial resistance (AMR) is a global health challenge in veterinary and human health, leading to monitoring of resistance and  promotion of responsible antimicrobial use. This survey assessed the use of antimicrobials among government veterinarians in Ogun  state, Nigeria. Clinicians were requested to fill questionnaires designed to extract information on the frequency of antibiotics use,  antibiotic prescription patterns and evaluation of perception on AMR and use of antibiotics with compromised efficacy in veterinary  practice in the last three years. Fifty-two (52) questionnaires were administered and duly completed upon return. Data analysis showed  100% awareness of AMR with 80.8% (42/52) agreeing to have encountered AMR in the course of managing small animal cases. The  tetracycline class of antibiotics 49(94.2%) was the most prescribed, followed by aminoglycosides 40(76.9%) and fluoroquinolones  35(67.3%). Empirical therapy (34/52) 65.4% is the most common treatment option among clinicians while 18 (34.6%) out of 52 clinicians  performed antibiotic susceptibility testing along with laboratory diagnosis as treatment guide. Furthermore, 75.0% of the respondents  affirmed administering antibiotics formulated for human use in small animal treatment. Thirty-three (63.5%) respondents administered  human antimicrobials in animals according to the recommended dosage in humans. This survey identified that AMR was common in  small animals in the state studied and this may be due to the irrational use of antibiotics. Promoting antimicrobial stewardship in small  animal medicine therefore is paramount to mitigating antimicrobial resistance and data obtained from this study will contribute to  developing evidence-based policy on the rational use of antibiotics in small animal practice in Nigeria.

For many decades, small-scale livestock, including rabbit production, has been a veritable pro-poor poverty alleviation venture in Africa.  With the rising population and increasing demand for food, the need to introduce and expand small-scale rabbit farms for long-term  sustainability cannot be overemphasized. While increasing the production and commercialization of domestic rabbit production is  desirable, the intensification of livestock also comes with some animal health problems. One of these is the emergence of Rabbit  Haemorrhagic Disease (RHD) caused by Rabbit Haemorrhagic Disease Virus (RHDV). The virus causes sudden death in rabbits, and does  not yet pose any public health risk. Symptoms of RHD may include: loss of appetite, lethargy, high fever, seizures, jaundice, bleeding from  natural orifices, difficulty in breathing and sudden death. The first known outbreak of RHD in Nigeria was reported in September  2020 at rabbit farms in Kwara and Oyo States,in Nigeria. Despite several intervention strategies, the disease has continued to spread  across the country. In this review, we search literature on the current state and knowledge of RHD as it affects rabbits and the economic  impact on livelihood and animal health implication of this emerging viral disease on rabbit farms in Nigeria.

Authors: Chikwe T.N. , Igwe C.E.
Published: September 2024

The physiochemical characteristics of oil and water obtained from the demusifier treatment of crude oil using equal concentrations of Cashew nutshell liquid (CSNL) and a commercial grade demulsifier (DX077) were evaluated. Results obtained shows that basic sediment and water (BSW) of the crude after treatment with CSNL and DXO77 were 17.5 and 17.9 % respectively which was 0.4% apart. The total oil and grease (TOG) and total petroleum hydrocarbon (TPH) of the produced water after treatment with CSNL were 24.4 and 21.7 mg/l respectively while results after treatment with DXO77 were 23.7 and 20.5 mg/l respectively. The TOG and TPH of the produced water after demulsifier treatment with CSNL and DX077 were within acceptable limit of < 30.0 mg/l as specified by Department of Petroleum Resources (DPR). Analyses of the same crude oil before demulsifier treatment gave a lower BSW of 9.50 % as well as an emulsion band of 16.2 % indicating improper oil/water separation. The TOG and TPH of the produced water before demulsifier treatment were 42.5 and 38.7 mg/l respectively which were above DPR specification. Disposal of produced water with high TOG and TPH into the environment can lead to the release of volatile organic compounds (VOCs) into the ecosystem resulting in environmental pollution as well as other health hazards. Results obtained also show that the water density, pH, electrical conductivity, salinity and chloride of the produced water after demulsifier treatment with CSNL and DX077 were within DPR specification. Reinjecting produced water with high salinity, chloride and conductivity into the reservoir can reduce oil recovery especially from sandstone and carbonate reservoirs. CSNL proved to be an effective demulsifier and is preferrable to the synthetic demulsifier (DX077) because it is more environmentally friendly owing to its green nature.

Published: September 2024

‘Ncha iwu’ is commonly used as a sauce in the preparation of ready-to-eat African salad, a wellknowndelicacy among the Igbo tribe in Nigeria. A total number of fifteen (15) samples of ‘ncha iwu’ were randomly purchased from three (3) vendors in Orie Ngodo and Eke Eziama market in Umunneochi Local Government Area of Abia state. The microbiological quality, proximate composition, and mineral content of the samples were determined using Standard Methods. ‘Ncha iwu’ prepared in the laboratory served as the control. The results showed that total bacterial, Staphylococcal, Coliform and fungal counts of the samples ranged from 3.81-4.37, 2.0-3.58, 3.0-3.8, and 2.0-3.0 log10 CFU/g, respectively. The bacterial species isolated and frequency of occurrence were Staphylococcus aureus (28 %), Klebsiella spp. (18 %), Pseudomonas spp. (18 %), Escherichia coli (18 %) while the fungal species were Penicillium spp. (50 %), Aspergillus spp. (40 %), and Candida spp. (10 %). Proximate analysis indicated that ‘ncha iwu’ contains ash (63.93%), moisture (15.88 %), fibre (8.99 %), lipid (7.70 %), protein (3.50 %) and carbohydrate (0.0 %) while minerals content include Fe (3.679 mg/g), Mg (1.055 mg/g), K (1.054 mg/g), Ca (1.030 mg/g), Mn (0.469 mg/g) and Na (0.222 mg/g). Although ‘ncha iwu’ contains beneficial nutrients, majority of the commercial samples were contaminated with potential pathogenic microorganisms which is a public health  concern unlike the control. This is as a result of poor handling by the producers and vendors. Good hygienic practices by the handlers, proper packaging and storage of ‘ncha iwu’ will reduce the microbial contamination of the product. Hence, adequate public health awareness campaign, training on food safety, sanitation and hygenic practices should be provided to the local processors and vendors of ‘ncha iwu’.

Agriculture, industrialization, transportation, urbanization and other anthropogenic activities have impacted on the natural cover of the earth surface, hence the dual concepts of land use and land cover (LULC). This study analyses spatio-temporal dynamics in LULC in part of southern Nigeria (path 189 and row 056) between 2002 and 2023using satellite imageries: namely, Landsat Enhanced Thematic Mapper Plus ETM+ of 2023, 2014 and 2002. The classification of land coverwas done with the aid of ArcGIS.The study revealed spatial dynamics in LULC over the study period. The percentage of the study area under cultivation increased from 7.96% in 2002, 17.79% in 2014 to 30.67% in 2023. Also, built-up area increased from 4.36% in 2002, 8.29% in 2014 but decreased to 7.06% in 2023. While areas of dense forest were 34.59% in 2002, 21.42% in 2014 and 11.57% in 2023, bare surface was 4.94% in 2014, 1.19% in 2002 and 25.34% in 2023.Oil spill was 6.13% in 2002, 6.42% in 2014 and 2.07% in 2023. Secondary regrowth/Plantation was 0.19%, 4.22% and 5.53% in 2002, 2014 and 2023 respectively. Water bodieswere 3.37% (2002), 7.06% (2002) and 11.27% (2023). The study recommends enactment of an enabling law or enforcement of existing laws governing forest protection and raising awareness and education of inhabitants on the need to preserve the natural land cover.
Micropaleontological and sedimentological analyses of carbonates rocks in parts of Sokoto Basin, Nigeria: implications for paleoecological interpretation and exploration efforts
Authors: Aigbadon G.O. , Igbinigie N.S.
Published: September 2024

This study presents a detailed analysis of the Paleocene and Maastrichtian marine sediments in the Sokoto Basin, Nigeria, using boreholes GSN – BH – 2051 and GSN – BH – 4051, respectively. This study is aimed at integrating sedimentological, micropaleontological and petrographic data in paleoecologic interpretation of depositional environments of the Sokoto Basin. The methods adopted in this research involved the examination of ditch cuttings, carbonate thin sections, and microfossils analyses from the boreholes drilled in Sokoto Basin. The sedimentological data from the borehole showed that the studied stratigraphic unit comprises mainly fine to medium-grained limestone facies, sparitic intraclastic packstone and oolitic-elmicrite wackestone facies. The microfacies obtained from petrography data revealed micro-fossils abundance and diversity associated with the onset of shallow marine transgression which resulted in the deposition of the Dange and Kalambaina Formations, respectively. The assemblages of the larger foraminifera (Opercullnoides bermudezi) and the larger ostracod (Bairdia iIaroensis) in the borehole sections further suggested marginal marine depositional environment for the Kalambaina and Gamba Shale Formations. The paleoecological interpretation suggests varying salinities and dysaerobic conditions during deposition, with implications for understanding basin evolution. The study concludes by highlighting the importance of integrating multiple methods for a detailed understanding of paleoecological and depositional environment of Sokoto sedimentary  basin.

Published: September 2024

The aim of this study is to provide baseline data on the investigation of concentrations of copper (Cu), lead (Pb), iron (Fe), manganese (Mn), and zinc (Zn) in various tissues (gills, intestine, liver, and fillet) of Parachanna obscura in Oguta Lake, and to assess physicochemical properties of Oguta lake to determine level of pollution and contamination. Twenty fish samples in total were collected at the fishermen landing site of the lake and analyzed using the Atomic Absorption Spectroscopy (AAS). Dissolved oxygen and temperature were measured on site using dissolved Oxygen meter (model 5509) and Mercury-in-glass thermometer respectively, while other parameters were analyzed in the laboratory. Results indicated Fe had the highest concentrations (1.479±0.003 mg/kg) especially in the gills, while Mn recorded least concentrations (0.001±0.000) mg/kg) of all metals analyzed. Values for Cu (0.026±0.002 mg/kg), Mn (0.001±0.000 mg/kg), Zn (.782±0.015 mg/kg), and Fe (1.479±0.030 mg/kg) levels were within FAO/WHO permissible limits in all tissues, whereas Pb (1.438±0.015 mg/kg) exceeded standard limits especially in the gills and intestines, indicating potential contamination and threats to aquatic and human health. Heavy metal concentrations in the tissues followed the order: gills > intestine > fillet > liver. The physicochemical properties assessment of Oguta Lake indicated a stable temperature with mean value of (28.02±022 C). The lake's temperature supports aquatic life, but challenges like low transparency (1.22±0.13 m), acidic pH levels (5.83±0.09), elevated ammonium levels (0.63±0.03 mg/l), low nitrate-nitrogen levels (0.0±50.00 mg/l), and fluctuating dissolved oxygen (6.50±0.29 mg/l) levels suggests pollution from agricultural runoff or sewage. The findings proffer effective management through pollution control, enhanced buffering capacity, and rigorous monitoring to safeguard biodiversity and ensure longterm ecological health.

We investigated and compared the constituents, antimicrobial, and antioxidant activities of the essential oils from the fresh and air- dried leaves of Icacina trichantha. The essential oils were extracted by hydrodistillation, antimicrobial activities were tested on Staphylococcus aureus, Salmonella typhi, Escherichia coli, Pleisomonas shigellosis, Bacillus cereus, Proteus vulgaris, Candida albicans, and Candida tropicalis by agar diffusion method, while 2,2- diphenyl-1-picrylhydrazyl (DPPH) was used for the antioxidant activities at 6.25-200 μg/mL of the oils compared with ascorbic acid as standard. The fresh and air-dried leaf oils gave 0.39% (w/w) and 0.33% (w/w) corresponding to 17 compounds representing 99.99%, and 10 compounds representing 100% respectively. Major compounds in the fresh leaf oil were 9-oxabicyclo [6.1.0] nonane (15.52%), Methyl isododecanoate(11.91%), Oleic acid (10.51%), 3-Cyclohexen-1-ol,3-methyl-(8.24%) and Phytol (7.70%), while Linoleic acid- (34.61%), Palmitic acid (20.74%), 9,17-Octadecadienal, (Z)- (12.98%), 9-Octadecenal (Z) (7.96%) and gamma-sitosterol (7.13%) were the major constituents of the air-dried oil. The fresh leaf oil 50 mg/mL, gave the highest zone of inhibition of 12 mm against Candida albicans while the air-dried oil had the highest zone of inhibition of 18 mm with a minimum inhibitory concentration of 0.20 mg/mL against C. tropicalis. The fresh leaf oil had the highest antioxidant activity of 73.85% at 100 μg/mL, while the air-dried and ascorbic acid had 70.25% and 69.23% respectively at 200 μg/mL. The fresh leaf oil comprised mainly oxygenated hydrocarbons (52.51%) while the air-dried oil had fatty acids (58.44%). Both oils were more antifungal than antibacterial and had a comparable antioxidant activity with ascorbic acid.

Published: September 2024

Cardiovascular diseases (CVDs) pose a formidable global health challenge, claiming millions of lives annually. Despite advancements in healthcare, heart disease remains a leading cause of mortality, especially in developing nations. Early detection of cardiac abnormalities through predictive models is crucial for effective intervention. This research leverages machine learning (ML) and artificial intelligence (AI), focusing on deep learning, to enhance diagnostic capabilities. Unlike previous studies, this work introduced caffeine as a potential risk factor often overlooked in datasets. The study utilized Magnetic Resonance Imaging (MRI) datasets from Enugu State University Teaching Hospital and Kaggle, comprising 90,500 samples, with specific attention to high caffeine intake cases. Data preprocessing involved resizing, normalization, color adjustments, and augmentation to optimize model training. A Convolutional Neural Network (CNN) architecture with four convolutional layers was employed for classification. The CNN model achieved a remarkable accuracy of 94% and low loss values, and demonstrated proficiency in categorizing heart MRI data. Ten-fold cross-validation reaffirmed the model's high success rate with an average accuracy of 94.13% and minimal loss function. Comparative analysis showcased the effectiveness of the developed CNN model, outperforming several existing models in heart disease classification.

Published: September 2024

This study investigates the effect of plantain peel ash as an admixture on concrete properties, which is a sustainable alternative to conventional concrete production. The aim is to optimize the mix design of concrete required for improved performance, investigate the effect of the plantain peel ash on the compressive strength of the concrete, and examine the effects of plantain peel ash as a supplementary material on the durability and service life of concrete. The use of plantain peel ash as an admixture for cement in concrete has gained increasing popularity due to its ability to reduce the environmental impact of concrete production. This study contributes to the understanding of the durability and performance of plantain peel ash in concrete which is crucial for sustainable construction practices. The methodology involves mix design according to IS 10262:2009 for M15 grade of concrete with 5%, 10%, 15% and 20% plantain peel ash replacement, testing of compressive strength and durability of the concrete samples and also the optimal dosage required, in comparison with conventional concrete. The result of this study shows that the addition of 5% plantain peel ash increases the compressive strength of the concrete with obtained value of 27.30 N/mm2 and also has the standard workability for a normal concrete at 45 mm for the control and 60 mm for 5% PPA. The 10%, 15% and 20% shows a decrease in their compressive strength compared to the control mix (0%) with a value of 18.42 N/mm2 for 28 days curing. Overall, it can be said that 5% plantain peel ash has provided a strong basis for the use of plantain peel ash in concrete mixtures. The 5% is equivalent to 0.72 kg  PPA.

Published: September 2024

The concentrations of gross alpha and gross beta radioactivity were analyzed in Aniocha South LGA of Delta State. Sediments were collected from randomly selected points on three major rivers in the LGA characterized by human activities, overpopulation, and industrialization. Standard methods were deployed for determination of gross alpha and gross beta radioactivity ineach sample by using an eight channel gas flow proportional counter and also to determine the concentrations of Cd, Pb, Cu and As in the water samples were done using chemical fraction method. The results show that the range of gross alpha and gross beta activity in the river sand sediment is 0.00014-0.00020 Bq/kg and 2.68-5.20 Bq/kg respectively. These results appear to be lower when compared with values from previous studies throughout the world, and WHO recommended limit. The results in this study showed that Pb, Cu, and As in the three river water samples are below the WHO recommended limit of 0.05, 1.5 and 0.05 ppm except for the value of Cd which is higher than the recommended limit of 0.005 ppm in one river water respectively. The pH level for the water samples was below World Health Organization (WHO) limit of 8.0. Similarly, the study could be a reference data for future research related to radiological mapping or environmental monitoring in the area.

This research method used a completely randomized design (CRD) consisting of four treatments and five replications, divided randomly based on treatment as follows: P0 Ration without adding BSF larval meal, P1 = BSF larval meal 3.183% (6.67% crude fish meal protein) , P2=BSF larval meal 6.370% (3.34% fish meal crude protein), P3=BSF larval meal 9.565% (0% fish meal crude protein). The variables observed were the consumption of crude protein, crude fat and crude fiber in quail. The data obtained were then analyzed using IBM SPSS Statistics 25 software. The results of the analysis of the effect of substituting fish meal with BSF larvae meal in the ration had no significant effect (P>0.05) on the consumption of crude protein, crude fat and crude fiber in quail.
Unveiling the Strategy Behind Blackfishing: Kim Kardashian's Instagram and the New Beauty Discourse
Authors: Lukitasari Breda Mukti , Saraswati Asri
Published: September 2024

As a fashion and beauty icon in America, Kim Kardashian is one of the public figures who supports the new beauty discourse. The emerging concept of new beauty in America challenges conventional limits for the delineation of beauty. This idea emphasizes that beauty is not limited by skin color, body shape, age, and hairstyle; instead, it emphasizes the need of embracing of natural body. This study examines how Kim Kardashian's personal Instagram posts from 2014-2023 showcases new notions of beauty via the lens of semiotic theory by Barthes (1964) and the concept of blackfishing. New forms of beauty discourse displayed by Kim Kardashian are accused of being blackfishing by excessively darkened skin, curvy body shapes, full lips, and hair. According to the findings of this study, there is a sense of ambivalence towards black women's bodies. Consequently, white people have internalized certain characteristics of black bodies without appreciating the unique qualities of black women. Kim Kardashian promotes a new beauty discourse that is considered blackfishing through her collaboration with the fashion and beauty industry and building her own cosmetics business. This demonstrates the participation of other influential individuals in the fashion business who endorse Kim's blackfishing appearance so that this appearance continues to appear in public and is normalized.

Travellers’ diarrhoea among tourists in Pakistan

Published: September 2024

Madam,
Travellers’ diarrhoea (TD) emerges as a significant health concern, especially within the South Asian region, which reports the highest Reporting Rate Ratios (RRR)1.
Making things even worse, the prolonged summer season in the region amplifies the frequency of reported TD cases, exacerbating the overall scenario2. Notably, travellers to low-income countries exhibit a RRR 150.9 times higher than travellers to high income countries1. Pakistan is no exception, experiencing many TD cases and potential complications among tourists. However, the recent surge in popularity witnessed over 960 million tourists engaging in international travel during 2022, which paves the path for a rise in TD incidence3.
Existing prevention and management approaches are constrained and primarily reliant on individual understanding and behaviours. Although travel advisories offer fundamental precautions, a dearth of all-encompassing guidance adapted to the distinct hurdles tourists encounter persists. Furthermore, Pakistan’s scarcity of resources positions it as the 3rd ranked country worldwide facing water shortage and sanitation challenges. Consequently, numerous travellers find themselves inadequately prepared to confront these risks. It becomes apparent that a more methodical and precise strategy is imperative to educate and empower tourists, offering them pragmatic tactics to diminish their vulnerability to TD.
Governments, tourism boards, and international organisations should collaborate on culturally tailored education about TD and prevention methods. This can be delivered through workshops, online resources, and campaigns, empowering travellers to make informed decisions.  Secure dining areas with hygiene certifications adhering to food safety standards, which should be continuously monitored by the Pakistan Standards and Quality Control Authority (PSQCA) is required to reduce health risks and improve travel experiences. Using mobile apps to empower travellers with informed choices, preventing hazard navigation related to hygiene, quality, pathogens such as Escherichia coli, Campylobacter jejuni etc. and high-risk assessment will provide a safer environment for foreigners. Continuous research should be promoted to manage strategies for evolving challenges and to find cheap and sustainable alternatives. Providing arrival information will equip travellers with prevention and management strategies for self-care. Multimedia campaigns in various languages should be initiated to educate communities and tourists, fostering hygiene commitment for safer travels. Encouraging tourists to get travel vaccinations will reduce the risk of TD for visitors in Pakistan. In conclusion, by implementing these strategies, we strive to ensure the well-being of foreigners and contribute to the broader goal of a healthier and safer tourism environment in Pakistan.
Pheochromocytoma-induced congestive heart failure and hypertension in a 21-year-old man-a Case Report
Authors: Chen Shuoxian , Chen Yufeng , Chen Pingan
Published: September 2024

Pheochromocytoma is a rare catecholamine-secreting mass which can lead to life-threatening cardiovascular complications and should be resected if confirmed. A 21-year-old male without any history of hypertension presented with congestive heart failure (HF) caused by pheochromocytoma-related cardiomyopathy; he was discovered to have hypertension at follow-up. A well-defined and uniform density mass was observed in his right adrenal region and confirmed to be pheochromocytoma. When the dilated left ventricle had become absolutely normal in size and hypertension was well controlled by medications, the patient needed no antihypertensive therapy at all after laparoscopic adrenalectomy at follow-up. Pheochromocytoma should be considered if HF occurred in patients, including young patients, with left ventricular enlargement and unknown medical history who initially presented with normal blood pressure. Even if the dilated left ventricle was restored and hypertension confirmed at follow-up, it could be well controlled by medications.
Keywords: Pheochromocytoma, Heart failure, Hypertension.

Published: September 2024

A rare condition known as Langerhans cell histiocytosis (LCH) is characterised by the clonal growth of dendritic cells called Langerhans cells, which play a significant role in the immune system. A diverse range of clinical presentations are probable as a result of this condition's ability to develop in different systems of the body. LCH presents with variable clinical manifestations, demonstrated by a range from specific multisystem involvement to more extensive bone abnormalities. This case report details the clinical course of a four-year-old male who presented with rash on the scalp and multiple lumps on the head for the past three months and a history of polyuria for two months. The findings were indicative of Langerhans cell histiocytosis after clinical and histological investigative studies. Moreover, endocrinological investigations demonstrated the development of       central diabetes insipidus, as a complication.
