Authors: Khan Mohammad Jesan , Asif Naiyer , Aggarwal Pankaj , Ashfaque Mohd Uzair , Ibran Mohammad
Published: May 2024

Ipsilateral fractures of femoral shaft and neck of femur fracture are rare but challenging and typically caused by high energy trauma. Review of literature shows various options for implants and surgical techniques for the treatment of Ipsilateral femoral neck shaft fractures but still none of them can be considered as standard, or even preferable. This is a case of 25 year old male who had suffered injury to his left hip and left thigh following an RTA. Radiographs of pelvis and thigh showed fracture of neck of right femur [basicervial] with fracture of shaft of right femur [junction of proximal 2/3rd and distal 1/3rd]. He was managed using reconstruction nail for both fractures 3 days after injury. The patient has attained bony union of both fractures in 8 months and was able to carry out his all routine activities and has attained good functional range of motion at hip and knee joint. We concluded that reconstruction nail is an acceptable implant for the management of ipsilateral neck and shaft of femur fracture with good radiological and clinical outcomes.
Precontoured anatomical plate fixation is not superior to recon plate fixation for intercondylar fracture humerus in adults
Authors: Adil Mohd , Julfiqar  , Sabir Aamir Bin , Aziz Mohd Hadi , Anwar Mohd Adnan
Published: May 2024

Introduction:

Intercondylar fractures are intraarticular distal humerus fractures that are frequently linked to osteopenia, comminution, and displacement. Due to its intricate anatomy, fractured bone frequently consists of many fragments and has few fixing possibilities. Open reduction and internal fixation (ORIF) is the best treatment option for these fractures, most commonly either with precontoured anatomical locking plates or recon plates. This study aims to compare the functional and radiological outcomes and rate of complications in the management of intercondylar fracture of the humerus with recon plates and precontoured anatomical plates.

Materials and Methods:

We have prospectively evaluated the outcome of precontoured anatomical plate vs recon plate fixation in the management of adult intercondylar fracture of the humerus in 20 patients having 10 patients in each of the groups. The study was done between November 2020 and November 2022. The recon plate group was designated as group 1 and the precontoured anatomic plate group as group 2. Orthogonal plate fixation was done in both groups. Ulnar nerve transposition was not done in any case. The study included seven patients of AO13C1, eight patients of AO13C2, and five patients of AO13C3 type of intercondylar fracture of the humerus. The mean follow-up period was 8.4 months. The functional outcome was assessed by the Mayo Elbow Performance Scoring (MEPS) system and the radiological outcome was by elbow anteroposterior/lateral radiographs. The minimum follow-up duration was 6 months.

Results:

In both groups, the average duration of operation and hospitalization was comparable. At 3 months follow-up after surgery, the mean MEPS in the locking precontoured anatomical plate group (group 2 = 82) was significantly higher than that of the traditional recon plate (group 1 = 69.50; P = 0.026). However, the mean MEPS was comparable in both the study groups (group 1 = 81.50, group 2 = 88, P = 0.154) at 6 months after the surgery. Range of motion (ROM) was comparable for each study group after 3 months and final follow-up as well. The patients in group 2 took much less time to achieve union than the patients in group 1 (P = 0.001); however, in total 95% of the study patients achieved union. The rate of complications including wound infection, tension band wire backout, implant loosening, and joint stiffness was similar in both groups.

Conclusion:

Precontoured anatomical plates and recon plates did not significantly differ in the functional results of distal humeral fractures (AO type 13C), including the ROM and MEPS at a mean follow-up duration of 8.4 months; however, there was a considerable variance in the union time, in which patients operated with precontoured anatomical plates showed much less time to achieve union than the recon plates.

Authors: Rathore Pankaj , Garg Sahil , Bhati Shivam
Published: May 2024

Background:

Plantar fasciitis is a common orthopedic issue that affects the quality of life. Various modalities of treatment have been tried for this condition, extending from conservative treatment to surgical treatment. Various studies have been conducted in different parts of the world to compare the results of local platelet-rich plasma (PRP) and steroids with varying results.

Materials and Methods:

We collected data at Mahatma Gandhi Medical College and Hospital, Jaipur, India with the approval of the IEC (Ethical Committee). From April 2016 to March 2017, 67 patients were included in the study through random sampling after obtaining written consent.

Results:

Plantar fasciitis was more common in the age group between 31 and 40 years. Plantar fasciitis was seen more commonly in females than males. Plantar fasciitis was seen more commonly in housewives and service providers. Both local steroid injection and autologous PRP injection are effective modes of treatment for chronic plantar fasciitis, but local steroid injection is effective for short-term pain relief, afterwards its effect gradually deteriorates, while autologous PRP injection provides better long-term pain relief. Patients were evaluated using the AOFAS score and the Visual Analogue Score, ranging from 0 to 10, at the onset of treatment, the 12-week follow-up, and the 24-week follow-up. An assessment was conducted in both categories.

Conclusions:

Both local steroid injection and autologous PRP injection are effective modes of treatment for chronic plantar fasciitis, but local steroid injection is effective for short-term pain relief (up to 12weeks as per our study), afterwards its effect gradually deteriorates, while the autologous PRP injection has better long-term pain relief.

Authors: Dholani Juhi I. , Chokshi Shraddha Pallav , Sanghvi Zarana K. , Menon Sidharth Santhosh
Published: May 2024

Stepwise caries excavation, being conceptualized for quite a time now, aims at phasic and thoughtful excavation of the diseased tissue, with a simultaneous attention to the fundamental principles of restorative dentistry. It has gained a humongous momentum conventionally, as the clinicians have eagle-eyed minimally invasive approaches for every possible treatment modality. The attempted case series showcases six cases of deep carious lesion managed by two-step caries excavation protocol in healthy patients diagnosed with chronic symptomatic reversible pulpitis, conclusively holding the longest favorable follow-up of over 3 years. This technique has a paramount clinical potential, conditional on appropriateness of case selection and clinical technique.
Endodontic management of severely calcified mandibular anterior teeth using guided endodontics: A report of a case and a review of the literature
Authors: Davaji Mina , Karimpour Sahar
Published: May 2024

Root canal calcification mainly occurs after physiologic dentin deposition throughout the aging process in elderlies or after traumatic injuries in young people, which can make endodontic treatment a challenge. The aim of this case report is to illustrate the successful endodontic treatment of severely calcified mandibular anterior teeth with the aid of “guided endodontics.” A 63-year-old Persian male patient was referred from the prosthetics department for root canal treatment of all six mandibular anterior teeth before his full-mouth reconstruction. Clinical examination showed severe attrition in all mandibular teeth with only the canines responding to sensitivity tests within the normal ranges. No tenderness to percussion and palpation or visible pocket depth was observed. Preoperative radiographs showed normal periodontal ligament spaces with no visible root canals within incisors, while the canines had moderately recessed pulpal spaces. A diagnosis of normal pulpoperiapical status was made. After precise clinical and radiographic examination, obtaining cone-beam computed tomographic images and digital intraoral scans, root canal treatments of the target teeth were performed using a custom-made three-dimensional model. A 4-month follow-up showed asymptomatic teeth, confirming that the endodontic guide is a useful tool to manage these cases safely. Previous case reports concerning “static guided endodontics” were also reviewed to identify the research gaps and the current limitations and benefits of the method.
The prevalence and causes of wrong tooth root canal treatment in Saudi Arabia: A cross-sectional survey
Authors: Al-Nefaie Abeer K. , Al-Beiruty Farah H. , Bakkar Mohammed Othman
Published: May 2024

Introduction:

Root canal treatment (RCT) is a common dental procedure performed by general dentists and endodontists. It is prone to complications, such as the wrong tooth treatment. The objective is to study the prevalence of wrong tooth RCT (WTRCT) among dental health-care practitioners in Saudi Arabia in addition to the causative factors leading to the treatment of the wrong tooth.

Materials and Methods:

A cross-sectional study was conducted among dentists (n = 393) in Saudi Arabia between May and November 2022. Respondent characteristics, WTRCT incident details, and procedures followed before RCT were collected from the survey. Minitab was used for the data analysis. Descriptive statistics, binary logistic regression, and t-test were used. A P < 0.05 was set for statistical significance.

Results:

The number of respondent dentists was 390. The prevalence of dentists performing WTRCT accounted for 6.9% (n = 27). Misdiagnosis 14.67% was the leading cause of WTRCT, followed by the simultaneous placement of a rubber dam with a clamp and miscommunication 13.33%. WTRCT is more likely to occur in dentists who have more than 10 years of clinical experience since graduation (P = 0.004). Endodontists were about six times more likely to have this error occur (P = 0.001).

Conclusions:

The prevalence of WTRCT among dentists in Saudi Arabia is 6.9%, with the majority being general dentists and endodontists. Posterior teeth are found to be the most involved site. It is important to spread awareness among dentists about WTRCT and to be more cautious while performing treatment on multirooted teeth.
The first experiences of preclinical dentistry students with rotary instruments: A pilot study
Authors: Büyükbayram Işıl Kaya , Çolakoğlu Gizem , Al-Shammari Sana Mahroos , Stoicefidis Katia
Published: May 2024

Introduction:

Rotary instrumentation has been included in the undergraduate endodontic curriculum to improve the quality of endodontic treatment. The aim of this study was to compare the technical quality of root canal fillings performed by preclinical dentistry students trained with hand instrumentation (THI) or not during their initial trial with rotary instruments.

Materials and Methods:

Twenty-four 3rd-year students were distributed into two groups: 12 students THI group and 12 students not trained with hand instrumentation (NTHI group). Both the groups received a 50-min theoretical lecture and a demonstration about the ProTaper Universal® system before being asked to complete endodontic treatments on one extracted maxillary central incisor, premolar, and molar using rotary instrumentation and obturation with the single-cone technique. The endodontic treatment technical quality was determined by periapical radiographs. Data were statistically analyzed, and P < 0.05 was considered statistically significant.

Results:

A total of 144 root canals were performed by preclinical students. Although the difference in the technical quality of the canals was nonsignificant among the groups (P > 0.05), the THI group had more adequately filled root canals (45.8%) than the NTHI group (29.2%). Only maxillary central incisors had underfilled canals, whereas teeth with multirooted canals were subjected to various procedural errors in both the groups (P > 0.05).

Conclusions:

Intensive hand instrumentation (HI) preclinical training did not significantly improve the technical quality of root canals performed by preclinical dentistry students during their initial trial with rotary instruments. The student’s familiarity with HI did not decrease the incidence of procedural errors when performing root canal treatment with rotary instruments.

Quasiconformal almost parametrizations of metric surfaces
Authors: Meier Damaris , Wenger Stefan
Published: May 2024

We look for minimal conditions on a two-dimensional metric surface

X

of locally finite Hausdorff 2-measure under which

X

admits an (almost) parametrization with good geometric and analytic properties. Only assuming that

X

is locally geodesic, we show that Jordan domains in

X

of finite boundary length admit a quasiconformal almost parametrization. If

X

satisfies some further conditions, then such an almost parametrization can be upgraded to a geometrically quasiconformal homeomorphism or a quasisymmetric homeomorphism. In particular, we recover Rajala’s recent quasiconformal uniformization theorem in the special case that

X

is locally geodesic as well as Bonk–Kleiner’s quasisymmetric uniformization theorem. On the way, we establish the existence of Sobolev discs spanning a given Jordan curve in

X

under nearly minimal assumptions on

and prove the continuity of energy minimizers.

Investigation of THOR-AV 5F Biofidelity in Sled Test Conditions with
a Semi-Rigid Seat
Authors: Wang Z. Jerry , Humm John , Hauschild Hans W.
Published: May 2024

THOR-AV 5F, a modified THOR-5F dummy, was designed to represent both upright and
reclined occupants in vehicle crashworthiness studies. The dummy was evaluated
in four test conditions: a) 25° seatback, 15 km/h, b) 25° seatback, 32 km/h, c)
45° seatback, 15 km/h, d) 45° seatback, 32 km/h. The dummy’s biomechanical
responses were compared against those of postmortem human subjects (PMHS) tested
in the same test conditions. The latest National Highway Traffic Safety
Administration (NHTSA) BioRank method was used to provide a biofidelity ranking
score (BRS) for each data channel in the tests to assess the dummy’s biofidelity
objectively. The evaluation was categorized into two groups: restraint system
and dummy. In the four test conditions, the restraint system showed good
biofidelity with BRS scores of 1.49, 1.47, 1.15, and 1.79, respectively. The
THOR-AV 5F demonstrated excellent biofidelity in three test conditions: 25°
seatback, 15 km/h (BRS = 0.76); 25° seatback, 32 km/h (BRS = 0.89); and 45°
seatback, 32 km/h (BRS = 0.93). In the fourth test condition, 45° seatback, 15
km/h, the dummy demonstrated good biofidelity with a BRS score of 1.06. The
dummy demonstrated good durability. No damage was identified with a full
inspection conducted after the tests.
Evaluation of DAMAGE Algorithm in Frontal Crashes
Authors: Prasad Priya , Barbat Saeed D. , Kalra Anil , Dalmotas Dainius J.
Published: May 2024

With the current trend of including the evaluation of the risk of brain injuries
in vehicle crashes due to rotational kinematics of the head, two injury criteria
have been introduced since 2013 – BrIC and DAMAGE. BrIC was developed by NHTSA
in 2013 and was suggested for inclusion in the US NCAP for frontal and side
crashes. DAMAGE has been developed by UVa under the sponsorship of JAMA and JARI
and has been accepted tentatively by the EuroNCAP. Although BrIC in US crash
testing is known and reported, DAMAGE in tests of the US fleet is relatively
unknown. The current paper will report on DAMAGE in NCAP-like tests and
potential future frontal crash tests involving substantial rotation about the
three axes of occupant heads. Distribution of DAMAGE of three-point belted
occupants without airbags will also be discussed. Prediction of brain injury
risks from the tests have been compared to the risks in the real world. Although
DAMAGE correlates well with MPS in the human brain model across several test
scenarios, the predicted risk of AIS2+ brain injuries are too high compared to
real-world experience. The prediction of AIS4+ brain injury risk in lower
velocity crashes is good, but too high in NCAP-like and high speed angular
frontal crashes.

Published: May 2024

Objectifs : Décrire le suivi et le pronostic des insuffisants cardiaques après leur sortie de l’hôpital.
Méthodes : Il s’agit d’une étude rétrospective, portant sur les patients hospitalisés dans le service de cardiologie du CHU Campus de Lomé entre janvier 2012 et décembre 2017.
Résultats : Sur les 70 patients inclus, l’âge moyen était de 54,7 ± 16,3 ans avec un sex-ratio (H/F) de 0,8. Les sujets âgés de 65 ans et plus représentaient 24,2%. Le taux de réhospitalisation globale était de 21,4% avec 60% de réhospitalisation dans l’intervalle d’une année. La mortalité était de 24,3% chez les femmes et de 15,7% chez les hommes (Logrank P = 0,50). La mortalité toutes causes à un an était de 40% et la moyenne d’âge des patients décédés était de 60,6 ± 14,5 ans. L’âge avancé était associé significativement à la mortalité (p < 0,001) ; 82,1% des patients décédés étaient aux stades III et IV de dyspnée de la NYHA lors de la première admission.
Conclusion : Le suivi des insuffisants cardiaques au CHU campus est émaillé d’un important taux de réhospitalisation avec une mortalité élevée à un an. Il s’avère alors utile d’améliorer le plateau technique du service de cardiologie afin de garantir une prise en charge adéquate de l’IC en vue de réduire ce taux important de décès.

Aims: To describe the follow-up and the prognosis of heart failure after discharge.
Methods: This is was a retrospective study, which included patients who had been hospitalized in the cardiology department of the Lomé University Hospital Center between January 2012 and December 2017.
Results: Overall 70 patients were included; the mean age was 54.7 ± 16.3 years with a sex ratio of 0.8. Patients aged 65 and over accounted for 24.2%. The overall readmission rate was 21.4% with 60% readmission within one year. Mortality rate was 24.3% for women and 15.7% for men (Logrank P = 0.50). The overall mortality rate at one year was 40% and the average age of the deceased patients was 60.6 ± 14.5 years. Older age was significantly associated with mortality (p <0.001); 82.1% of the deceased patients had dyspnea NYHA stage III or IV at their first admission.
Conclusion: The follow-up of heart failure patients in the University hospital of Campus was characterized by a high rate of readmissions with high mortality rate at one year. It is therefore useful to improve the technical platform of the cardiology department to ensure adequate management of heart failure patients to reduce this high rate of death.

La crevette géante tigrée, Penaeus monodon (Fabricius, 1798) est pêchée de façon régulière dans l’estuaire inversé de Casamance depuis 2012 par les pêcheurs migrants maliens. Sa présence dans cet estuaire est atypique, car ce n’est pas son habitat naturel. Les principales zones de pêche pour cette ressource sont les affluents et le cours principal de l'estuaire de Casamance, s'étendant de l'embouchure des cours d'eau à la ville de Ziguinchor. Dans cette zone, la crevette géante tigrée est capturée à l'aide d'un filet maillant dérivant de fond, qui est également utilisé pour la pêche du Drepane africana, Arius spp et Plectorhuncus spp. Les débarquements de la crevette géante tigrée dans l'estuaire de la Casamance sont analysés et discutés dans cet article scientifique. Les données sont collectées à Ziguinchor, le principal marché de commercialisation de l’espèce en Casamance. Cette étude a permis d'évaluer les quantités de crevettes tigrées débarquées sur la période allant de 2012 à 2018, se situant entre 3 et 9 tonnes par an, sur une période de pêche de trois à cinq mois. Une analyse de variance entre les tonnages débarqués et le nombre d'engins de pêche ciblant l'espèce indique une différence significative dans les résultats d'une année à l'autre. Les résultats obtenus ont permis de déterminer que la principale période d'abondance de la ressource dans la zone de pêche se situe pendant la saison chaude sèche, entre les mois d'avril et juin.
The giant tiger shrimp, Penaeus monodon (Fabricius, 1798) has been regularly fished in the inverted Casamance estuary since 2012 by Malian migrant fishermen. This presence in the estuary is atypical because it is not its natural habitat. The tributaries and the main course of the Casamance estuary, stretching from the mouth of the river to the town of Ziguinchor, constitute the primary fishing zones for the fishing units targeting this resource. In this area, the giant tiger shrimp is exclusively captured using bottom drifting gillnets. The drift gillnet, which targets Drepane africana, Arius spp, and Plectorhuncus spp, is loaded onto the same canoe for fishing the fish. Landings of the giant tiger shrimp in the Casamance estuary are analyzed and discussed in this scientific article. The data is collected in Ziguinchor, the main marketing market for the species in Casamance. This study enabled the evaluation of the quantities of tiger shrimp landed from 2012 to 2018, ranging between 3 and 9 tons per year over a fishing period of three to five months. An analysis of variance between the landed tonnages and the number of fishing gears targeting the species indicates a significant difference in the results recorded from one year to the next. The obtained results pinpointed the main period of the abundance of the resource in the fishing zone during the hot dry season, between April and June.

Indiscriminate dumping of battery waste is a huge issue that endangers human health and the environment. This study aimed at analysing the health impacts of exposure to pollution from spent battery recycling in Ogun State, which houses a diverse range of battery recycling industries. At this study site, forty water samples were studied over the Wet and Dry seasons to assess the impact of battery recycling waste on groundwater. Except for the TSS, the physiochemical parameters of the groundwater vary with season and are within the permissible limits. The electrical conductivity (EC), turbidity, Phosphorus, Biochemical oxygen demand (BOD), Dissolve oxygen (DO), and Total suspended solid (TSS) within the study year ranges from 51.00 - 178.22 S/cm, 2.26 - 2.36 NTU, 0.089 - 0.66 mg/L, 13.3 - 14.2 mg/L, 5.06 - 5.67 mg/L, and 78.0 - 88.4 mg/L, respectively. Furthermore, the average concentrations (in ppm) obtained for Mn, Cu, Zn, Ni, Cd, As, Fe, Pb, Cr, and Co are 0.407 – 0.42, 0.355 – 0.369, 0.179 – 0.225, 0.061 – 0.265, 0.366 – 0.464, 0.488 – 0.631, 0.544 – 0.601, 0.481 – 0.576, 0.284 – 0.334, 0.3 – 0.382. The Heavy Metal Pollution Index (HPI) values ranging from 3.880 to 4.528 indicate minimal levels of heavy metal contamination, but water quality index (WQI) scores ranging from 124.68 to 131.46 indicate potential environmental hazards.

Authors: Andrew Samora Macrice
Published: May 2024

Understanding of species composition of village land forest reserves and their driving factors informs adequate development of effective restoration strategies and sustainable forest management of miombo woodlands. This study assessed the effects of human disturbance as well as environmental variables on woody plant species composition using 24 square plots of 10 x 10 m in a recently declared village land forest reserve in the Eastern Afromontane biodiversity hotspot of Tanzania. Ordination analysis technique canonical correspondence analysis was used to identify important vegetation gradients and significant factors that explain the spatial variation in species composition of woody plants. Results showed that, 779 individual woody plants were recorded, of which 379 were seedlings (48.6%), 102 saplings (13.1%) and 298 adults (38.3%). The three most dominant plant species were Brachystegia spiciformis (42.2%), Diplorhynchus condylocarpon (9%) and B. boehmii (8.7%), while the least were Multidentia crassa and Diospyros squarrosa with each species having less than 1% overall abundance. Pterocarpus angolensis, a highly protected and near-threatened tree species, was also recorded but with only very few individuals. Canopy cover and soil pH were the two most important variables explaining the spatial variation in species composition of woody plants. These results emphasise that village forests are important for preserving native and threatened tree species, and improved management should discourage all practices that change natural conditions of canopy cover and soil pH to safeguard the remaining village forests, biodiversity and rural livelihoods.

The Sanjika, Opsaridium microcephalum is among the fish species that serve as a major source of proteins and income to people along Lake Nyasa. However, the information on its genetic diversity and structure particularly in the Tanzania part of the Lake is limited. Therefore, the assessment of the genetic diversity and structure of O.microcephalum along the Lake Nyasa part of Tanzania was conducted in the current study using a fragment of the mitochondrial COI gene from 92 individuals of O. microcephalum. The findings showed that an average haplotype diversity and average nucleotide diversity were 0.8065 ± 0.0314 and 0.002380 ± 0.001640, respectively. The molecular Variance (AMOVA) indicated significant genetic variations among the subpopulations studied (Overall Φst = 0.31560, p < 0.001). The lowest haplotype diversity was recorded at Manda and the highest haplotype diversity was recorded at Buloma. The lowest nucleotide diversity was recorded at Manda and the highest was recorded at Lupingu. The differences in genetic diversity can be a possible indicator of different localised evolutionary forces that require attention to conservationists for the sustainable management of O. microcephalum

Demand for surimi-based products has surged due to their convenience, and high protein content. However, the production process generates a large amount of nutrient-rich wastewater (SWW), which is beneficial to microalgae. Hence, the purpose of this study was to examine how six marine microalgae species grew at varying concentrations of SWW and extra nutrients (molasses-M, sodium nitrate-SN, ferric chloride-FC). The cultivation was conducted for ten days in a controlled environment, including aeration, light exposure, and temperature (22-27°C). Results showed that a 10% SWW promoted maximum biomass and nutrient removal, with Nannochloropsis oculata achieving 5.15 ± 1.27 g/L biomass, 80% NO3-, 100% PO43-, and 48% COD reduction. Under additional nutrient supplementations, microalgae achieved higher biomass, reaching 5.79 ± 0.24 g/L, with complete PO43- and NO3- removal, and COD reduction (71.54% − M : FC and 80.32% − M : SN). Additionally, the protein content was considerably raised by both SN and FC (32.41 ± 2.21% and 27.15 ± 0.88%), whereas the lipid content was decreased by SN (20.05 ± 1.36%) and increased by FC (27.38 ± 1.17%). This research highlights the potential of SWW for marine microalgae growth and the impact of nutrient supplementation, offering valuable insights in the field of bioresource technology.

An Alternative Proof for the Expected Number of Distinct Consecutive Patterns in a Random Permutation
Authors: Godbole Anant , Swickheimer Hannah
Published: May 2024

Let $\pi_n$ be a uniformly chosen random permutation on $[n]$. Using an
analysis of the probability that two overlapping consecutive $k$-permutations
are order isomorphic, the authors of a recent paper showed that the expected
number of distinct consecutive patterns of all lengths $k\in\{1,2,\ldots,n\}$
in $\pi_n$ is $\frac{n^2}{2}(1-o(1))$ as $n\to\infty$. This exhibited the fact
that random permutations pack consecutive patterns near-perfectly. We use
entirely different methods, namely the Stein-Chen method of Poisson
approximation, to reprove and slightly improve their result.
