[Role of cranioplasty in the management of decompressive craniectomies: Study of the Adolphe de Rothschild Foundation Hospital cohort over 7 years]. / Place de la cranioplastie dans la prise en charge des crâniectomies décompressives : étude de la cohorte de l'Hôpital Fondation Adolphe de Rothschild sur 7 ans.

OBJECTIVES: The objective of our study is to take stock of the cranioplasty implants used within our establishment. MATERIALS AND METHOD: We analyzed the patients files who underwent craniectomy followed by cranioplasty between 2017 and 2023, with at least 1 year of follow-up after cranioplasty (n=75). The data were extracted from the computerized patient file (DxCare®, Dédalus) and the pharmaceutical management tool for drugs and sterile medical devices (Pharma®, Computer Engineering). The sex ratio, indication for craniectomy, operating time, time between craniectomy and cranioplasty, complications and aesthetic result were statistically analyzed. RESULTS: The main indications are stroke (n=59; 78.5%) and aneurysms (n=7; 9.5%). Among the 75 patients, 52 benefited from the placement of a custom implant (PolyEtherEtherCetone/PEEK or Hydroxyapatite) and 23 from cementoplasty. The operating time was significantly shorter (P<0.05) for custom cranioplasty (1.93±0.61h vs. 1.62±0.53). Only 4 patients (5.3%) were not satisfied with the aesthetic result following the placement of a custom implant. A greater risk of infection was found in the context of cementoplasty (43% for cementoplasties vs. 25% for the custom implant, so χ2 (P=0.1095), this difference not being statistically significant. CONCLUSION: This collaborative work between the pharmacy and the adult neurosurgery department served to establish an initial register for monitoring patients who have undergone cranioplasty for whom the ideal implant remains to be determined.

Ophthalmic findings and reference values for selected ocular parameters in whooping cranes (Grus americana) and Mississippi sandhill cranes (Grus canadensis pulla).

OBJECTIVE: To establish baseline ophthalmic parameters for an endangered, semi-wild population of healthy whooping cranes (Grus americana) (WHCR) and Mississippi sandhill cranes (Grus canadensis pulla) (SACR). ANIMALS STUDIED: Eighteen WHCR and 16 SACR. PROCEDURES: Ophthalmic examination was performed by a single observer, followed by conjunctival swab collection for aerobic bacterial culture and measurement of tear production (phenol red thread test, PRTT) and corneal diameter (CD) as tolerated. Measurement of the axial globe (AG) length, anterior chamber (AC) depth, lens thickness, vitreous chamber (VC) depth, and pecten length was performed via ocular ultrasound (OUS) as tolerated. RESULTS: Eyelid cicatrization (n = 1 WHCR), keratitis (n = 2 WHCR), incipient cataracts (n = 1 WHCR, n = 4 SACR), and uveal cysts (n = 1 SACR) were identified. Twenty-one bacterial species were cultured from SACR, while 18 bacterial species were cultured from WHCR. SACR under 6 months old had increased PRTT values compared to older SACR (p = .0432). AG length and VC depth of male WHCR were greater than in female WHCR (p = .0045 and p = .0008, respectively). WHCR less than 6 months old had greater AC depth and lens thickness than WHCR over 6 months (p < .001 and p = .0013, respectively). SACR less than 6 months old had greater AC depth and lens thickness than WHCR over 6 months (p < .0001 and p < .0001, respectively). CONCLUSIONS: WHCR and SACR are amenable to complete ophthalmic examination. Age-related differences in PRTT in SACR, sexual dimorphism in WHCR, and age-related differences in AC depth and lens thickness in WHCR and SACR were identified.

Original Training for Laparoscopic Surgery by Making an Origami Paper Crane.

INTRODUCTION: The training box is an effective tool used by surgical trainees. Suturing training is the common method of practicing laparoscopic surgery; however, the cost of needles and threads for long-term practice remains a problem. In this study, we incorporated the original Japanese training for laparoscopic surgery by making an origami paper crane (laparoscopic origami training (LOT)) and evaluated its effect on the clinical results as a long-term practice. METHODS: LOT was performed using a single 7.5 × 7.5 cm origami paper in the training box of laparoscopic surgery. In the bench-top study, the total time required to make one paper crane was measured and evaluated, and a self-efficacy questionnaire was designed to analyze the efficacy of LOT. In clinical practice, we retrospectively compared two resident groups, one that had previously trained on LOT (trained group) and the other that did not (less-trained group), by analyzing the pneumoperitoneum time (PT) for 10 cases. RESULTS: After making paper cranes in approximately 100 cases, the making time was reduced to approximately 10 min. Long-term results analyzing up to 1500 cases revealed that in addition to shortening the time required to make a paper crane, the shape of the crane also improved. Consequently, the median PT was significantly shorter in the trained group than in the less-trained group (129.0 (62-287) versus 208.5 (127-343) min; p<0.001). CONCLUSION: LOT contributed to introducing safe laparoscopic surgery to residents and improved their laparoscopic outcomes. We believe that this is a useful practice methodology that can be recommended to general physicians who wish to practice laparoscopic surgeries.

[The useful forehead, the impaired forehead, but the forehead repaired!] / Le front utilisé, le front traumatisé, mais le front réparé !

The forehead, although sometimes hidden by a fringe, is a major region of the face revealing many expressions such as fatigue, surprise, concern, anger… In reconstructive surgery, the forehead is frequently used as a donor site. This article looks at three aspects: the used, traumatised and repaired forehead. The forehead, with its high-quality hairless skin and proximity to the noble structures of the face, is a central donor site. The forehead flap is commonly used for nasal reconstruction, with several variations to meet different needs. Other pedicled flaps, such as the supra-eyebrow flap and the crane flaps, are also used for various facial reconstructions. The forehead can be affected by trauma, burns, vascular lesions and skin tumours. We are particularly interested "en coup de sabre" linear scleroderma, an autoimmune disease that causes cutaneous and subcutaneous fibrosis, sometimes associated with Parry Romberg syndrome. In addition, lesions of the temporal branch of the facial nerve lead to muscular paralysis, affecting the aesthetics and function of the frontal region. Precise knowledge of the anatomy of the nerve pathway is crucial to avoid iatrogenic lesions. The entire arsenal of reconstructive surgery is useful for repairing the forehead. Controlled wound healing, tension suturing and the use of local flaps are key techniques for repairing the forehead. Tension sutures are particularly effective for small losses of substance, and their orientation depends on the location. Advancement, rotation and transposition flaps are used for larger losses of substance. Skin grafts, although less aesthetic, are sometimes necessary. Skin expansion, although socially restrictive, is used to treat congenital giant nevi and increase the surface area of forehead flaps.

Evaluation of airborne asbestos concentrations associated with the maintenance of brakes on an industrial overhead crane.

OBJECTIVES: To evaluate potential airborne asbestos exposures during brake maintenance and repair activities on a P&H overhead crane, and during subsequent handling of the mechanic's clothing. METHODS: Personal (n = 27) and area (n = 61) airborne fiber concentrations were measured during brake tests, removal, hand sanding, compressed air use, removal and reattachment of chrysotile-containing brake linings, and reinstallation of the brake linings. The mechanic's clothing was used to measure potential exposure during clothes handling. RESULTS: All brake linings contained between 19.9% to 52.4% chrysotile asbestos. No amphibole fibers were detected in any bulk or airborne samples. The average full-shift airborne chrysotile concentration was 0.035 f/cc (PCM-equivalent asbestos-specific fibers, or PCME). Average task-based personal air samples collected during brake maintenance, sanding, compressed air use, and brake lining removal tasks ranged from 0 to 0.48 f/cc (PCME). The calculated 30-minute time-weighted average (TWA) airborne chrysotile concentration associated with 5-15 minutes of clothes handling was 0-0.035 f/cc PCME. CONCLUSION: The results indicated that personal and area TWA fiber concentrations measured during all crane brake maintenance and clothes handling tasks were below the current OSHA 8-h TWA Permissible Exposure Limit for asbestos of 0.1 f/cc. Further, no airborne asbestos fibers were measured during routine brake maintenance tasks following the manufacturer's maintenance manual procedures. All short-term airborne chrysotile concentrations measured during non-routine tasks were below the current 30-minute OSHA excursion limit for asbestos of 1 f/cc. This study adds to the available data regarding chrysotile exposure potential during maintenance on overhead cranes.

[Prospective longitudinal study on the evolution of autobiographical memory in patients irradiated for benign skull base tumour]. / Étude prospective longitudinale sur l'évolution de la mémoire autobiographique de patients irradiés pour une tumeur bénigne de la base du crâne.

PURPOSE: Cranial irradiation can lead to long-term neurological complications, in particular memory disorders. The aim of this prospective study is to evaluate the impact of irradiation of benign skull base tumours located near the hippocampi on autobiographical memory. PATIENTS AND METHODS: From 2016 to 2019, patients with cavernous sinus meningioma or pituitary adenoma treated with normofractionated irradiation were included. Patients underwent full neuropsychological assessment at baseline, 1year and 2years post-treatment. Neuropsychological tests were converted to Z-Score for comparability. RESULTS: Twelve of the 19 patients included had a complete neuropsychological evaluation at 2years and were analysed. On the "TEMPau" test, no significant difference in autobiographical memory was found at 2years, regardless of the period of autobiographical memory. The mean hippocampal dose had no impact on the variation in autobiographical memory. There was no significant cognitive impairment in the other domains assessed, such as attention, anterograde memory, working memory and executive functions. Autobiographical memory was independent of these other cognitive domains, which justifies its specific study. CONCLUSION: Radiotherapy to the skull base for a benign pathology does not lead to significant cognitive impairment. Longer follow-up would be needed to confirm these results.

Recent Advancements in Pectus Surgery: Crane Lifting, Multiple-Bar Approach, Bridge Stabilization, and Sandwich Technique.

PURPOSE: The most recent procedure for pectus excavatum repair involves crane-powered entire chest wall remodeling, which employs crane lifting, multiple-bar approach, bridge stabilization, and sandwich techniques. This resulted in a paradigm shift in pectus deformity repair from merely lifting the sunken bone to remodeling the chest wall into normal anatomy. METHODS: We analyzed 649 patients who underwent surgery for pectus excavatum or complex combined deformities between March 2018 and January 2022. A crane with sternal wiring or screwing was used to lift the chest wall without using the pectus bar turning power. Multiple bars with bridge connections were placed to eliminate bar displacement. Modified sandwich techniques were applied to relieve the lower coastal flare (flare-buster) and focal protuberance (magic string). RESULTS: The mean age of the patients included in the study was 12.2 years (range: 3-45 years). A single bar was used for 202 patients until 2021. For the multiple-bar technique, parallel bars (n = 142), crossbars (n = 166), and crossbars plus upper horizontal bars (XI pattern; n = 139) were used. The overall complication rate was 6.2 %. There was no cases of bar displacement were observed, but other minor complications such as pneumothorax (n = 20, 3.1 %), pleural effusion (n = 7, 1.1 %), and wound infection (n = 5, 0.8 %) were detected. Three patients required reoperation (infection, two: hemorrhage, one). CONCLUSIONS: The crane-powered entire chest wall remodeling technique improved the safety and comprehensiveness of the repair procedure. By incorporating bridge stabilization and the use of multiple bars, we effectively resolved the issues related to bar displacement and incomplete repair. TYPE OF STUDY: Retrospective Cohort Study.

Interest of a 3D custom-made implant in the reconstruction of bone defects of the cranial vault.

The authors report a case of a patient managed for severe cranial vault depression following combined neurosurgery and radiotherapy. This situation caused major aesthetic discomfort and was potentially dangerous due to the mechanical weakness of the bone flap. The authors had a CAD (computer aided design) silicone elastomer custom-made implant made to fill perfectly the depression. Beforehand, an expansion was performed to cover the implant after removal of the radiated skin. The surgery and post-operative course raised no concerns. After one year of follow-up, the result is very good and the patient very satisfied, proving that this technique certainly has its place in the therapeutic arsenal when faced with a tissue defect of the cranial vault.

Intrahepatic Cholangiocarcinoma Identified in a Zoo-Housed Sandhill Crane (Grus canadensis): An Anatomopathological and Metagenomic Study.

Tumors in birds can be caused by a variety of factors such as species, age, sex, virus, chemicals, and environment. In particular, tumors are a major cause of death in long-lived birds such as parrots and zoo birds. A male sandhill crane that was bred for 8 years in a zoo was diagnosed with intrahepatic cholangiocarcinoma (ICC). At necropsy, the liver revealed a multinodular mass of variable colors, and severe cirrhosis and hemorrhages were present. Histologically, ICC was characterized by the presence of both types of ICC: small-duct type and large-duct type. Large-duct-type ICC was distinguished by the presence of multifocal biliary neoplasia, characterized by the diffuse papillary proliferation of columnar cells resembling large cholangiocytes. Small-duct-type ICC was characterized by the presence of non-mucin-producing cuboidal cells such as bile duct cells. In this case, no viral cause was identified from the metagenomic analysis and PCR of ICC; however, a contributing role of Cutibacterium sp. and E. coli identified from the metagenomics could not be excluded. This study is the first to describe the anatomopathological characteristics of ICC in the studied sandhill crane and attempts to determine its potential infectious etiology using metagenomics.

Genomic and Pathologic Characterization of the First FAdV-C Serotype 4 Isolate from Black-Necked Crane.

Fowl adenoviruses (FAdVs) are distributed worldwide in poultry and incriminated as the etiological agents for several health problems in fowls, and are capable of crossing species barriers between domestic and wild fowls. An FAdV strain was, for the first time, isolated from black-necked crane in this study, and was designated as serotype 4 Fowl aviadenovirus C (abbreviated as BNC2021) according to the phylogenetic analysis of its DNA polymerase and hexon gene. The viral genomic sequence analysis demonstrated that the isolate possessed the ORF deletions that are present in FAdV4 strains circulating in poultry fowls in China and the amino acid mutations associated with viral pathogenicity in the hexon and fiber 2 proteins. A viral challenge experiment with mallard ducks demonstrated systemic viral infection and horizontal transmission. BNC2021 induced the typical clinical signs of hepatitis-hydropericardium syndrome (HHS) with swelling and inflammation in multiple organs and showed significant viral replication in all eight organs tested in the virus-inoculated ducks and their contactees at 6 dpi. The findings highlight the importance of surveillance of FAdVs in wild birds.

Low estradiol production of non-laying whooping cranes (Grus americana) is associated with the failure of small follicles to enter follicular hierarchy.

For endangered species managed ex situ, production of offspring is a key factor to ensure healthy and self-sustaining populations. However, current breeding goals for the whooping crane (Grus americana) are impeded by poor reproduction. Our study sought to better understand mechanisms regulating ovarian function in ex situ managed whooping cranes and the regulatory function of the hypothalamic-pituitary-gonadal (HPG) axis in relation to follicle formation and egg laying. To characterize hormonal regulation of follicular development and ovulation, we collected weekly blood samples from six female whooping cranes during two breeding seasons, for a total of 11 reproductive cycles. The plasma samples were assessed for follicle stimulating hormone, luteinizing hormone, estradiol, and progesterone and the yolk precursors vitellogenin and very low-density lipoprotein. Ultrasonographic examination of the ovary was conducted at the time of blood collection. Preovulatory follicles (>12 mm) were present in laying cycles (n = 6) but absent in non-laying cycles (n = 5). The patterns of plasma hormone and yolk precursor concentrations corresponded to the stage of follicle development. Specifically, gonadotropin and yolk precursor concentrations increased as follicles transitioned from the non-yolky to yolky stage but did not increase further as the follicle advanced to preovulatory and ovulatory stages. Estrogen and progesterone concentrations increased as follicle size increased and reached peak concentrations (P < 0.05) when follicles developed to ovulatory and preovulatory stages, respectively. While overall mean circulating gonadotropin, progesterone, and yolk precursor concentrations did not differ for laying versus non-laying cycles, mean plasma estradiol in laying cycles was significantly higher than that in non-laying cycles. In summary, the findings suggested that disruption of mechanisms regulating follicle recruitment is likely responsible for the oviposition failure of the captive female whooping crane.

The Gantry Crane Technique: A Novel Technique for Treating Severe Thoracic Spinal Stenosis and Myelopathy Caused by Ossification of the Ligamentum Flavum and Preliminary Clinical Results.

STUDY DESIGN: Retrospective single-arm study. OBJECTIVE: To propose a novel technique named the gantry crane technique for treating severe thoracic spinal stenosis and myelopathy caused by thoracic ossification of the ligamentum flavum (TOLF) and investigate its clinical results. METHODS: From June 2017 to January 2019, 18 patients presenting with severe spinal stenosis and myelopathy caused by TOLF were included in our study. All patients were treated with gantry crane technique, pre-operative JOA score, as well as 3 days-, 3 months-, 6 months-, 12 months-, 24 months after operation, and Hirabayashi recovery rate were reported. Pre- and post-operative image were utilized for the assessment of post-operative effect. Peri-operative complications were recorded to assess the safety of the gantry crane technique. RESULTS: The JOA score increased from 10.56 ± 3.76 preoperatively to 12.94 ± 3.33, 13.56 ± 3.48, 13.94 ± 3.32, 14.17 ± 3.70 and 14.06 ± 3.54 in 3 days, 3 months, 6 months, 12 months and 24 months after surgery, respectively. The post-operative JOA scores were improved with statistical significance at the level of P < 0.05. The recovery rate was (39.09 ± 33.85) %, (51.35 ± 42.60) %, (55.79 ± 36.10) %, (64.98 ± 29.24) % and (60.98 ± 35.96) % for 3 days, 3 months, 6 months, 12 months and 24 months after surgery, respectively. There were 2 cases of SSI (surgical site infection), 1 case of NI (neurovascular injury) and 1 case of cerebrospinal fluid (CSF) leakage. CONCLUSIONS: This study highlights a safe and effective technique, the gantry crane technique, for treating severe thoracic spinal stenosis and myelopathy caused by TOLF.

Comparison of Surgical Results of the Bridge Crane Technique Versus Laminectomy for the Treatment of Thoracic Myelopathy Caused by Ossification of the Ligamentum Flavum.

STUDY DESIGN: A retrospective study. OBJECTIVES: This study aimed to evaluate the safety and effectiveness of the bridge crane technique versus laminectomy for the treatment of thoracic myelopathy caused by ossification of the ligamentum flavum (OLF). METHODS: Totally 41 patients who underwent surgical decompression due to thoracic OLF from May 2017 to June 2018 in our institution were enrolled in this study and were divided into group BG (bridge crane technique, n = 19) and group L (laminoectomy, n = 22). Demographic data was collected from medical records and the modified Japanese Orthopaedic Association (JOA) scoring system was used to evaluate the neurological outcomes during the follow-up. Surgery-related complications were analyzed. RESULTS: The mean duration of follow-up was comparable between group BG (19.4 ± 1.5 months) and group L (19.6 ± 1.4 months). No statistical differences were observed between two groups in terms of gender, age, duration of symptoms, preoperative occupying rate, involved levels, operation time, intraoperative blood loss, and complications. The JOA score significantly increased at the final follow-up in both groups. However, patients in group BG had higher JOA score and recovery rate (P < 0.05). Four patients in group L experienced complications, including 3 cerebrospinal fluid (CSF) leakage and one postoperative hematoma. Only one patient in group BG had CSF leakage. CONCLUSION: The results of this study suggested that bridge crane technique may be relatively safe and effective for patients with symptomatic thoracic OLF with more satisfactory clinical improvement. However, high-quality studies are still required to validate the results of this study.

Crane-powered pectus excavatum repair: the NeoPectus surgery.

Introduction: The conventional technique for pectus excavatum repair was pushing up the depressed chest wall by turning over the convexity of the bent pectus bar. We developed a new concept in which a total crane lift was used as the source of power to elevate the depressed sternum without using pectus bar leverage. This study aims to verify the efficacy of exclusively crane-powered pectus excavatum repair in recent years. Methods: Among the 3622 pectus deformity repairs since 1999, 691 cases repaired with the total crane power between 2017 and 2022 were enrolled. The mean age was 12.0 years (3-45). The operative technique involved wire/screw crane elevation of the sternum, the entire chest wall remodeling with the cross or parallel bars, the bridge/claw bar fixations, and other adjunctive techniques. Outcome analysis included morphological variations, patterns of pectus bar placement, and complication rates. Results: The crane technique and pectoscopy (100%) were used. The bar placements were parallel (22.0%) and cross-bar (47.5%). The bar fixations were the claw fixators for a single bar (30.5%) and the bridge plates for multiple bars (69.5%). The flare-buster and magic strings were liberally used. No serious complications or catastrophic events occurred, but minor complications occurred in 16.9%: pneumothorax in 7.4% (51), pleural effusion in 1.6% (11), and wound problems in 0.4% (3). There was no case of bar displacement. Discussion: The crane-powered pectus excavatum repair showed excellent results with minimal complications and no bar displacement. This innovative approach, part of the NeoPectus surgery, represents a significant advancement in correcting pectus excavatum deformities by utilizing a crane machine to elevate the chest wall.

The evaluation of the correlation between origami crane training and Fundamentals of Laparoscopic Surgery (FLS).

Objective: How does making origami cranes under a dry box affect Fundamentals of Laparoscopic Surgery (FLS) scores in medical students? Design: Four medical students from Asahikawa Medical University (tertiary hospital) participated. They made origami cranes under a dry box (origami crane training) five days per week for four weeks. The time required to make each origami crane (origami crane time) and degree of completion were evaluated. FLS scores were measured before training and on days 5, 10, 15, and 20. We examined the relationship between "origami crane training" and FLS scores. Results: At the beginning of the experiment, none of the participants could complete the origami crane, but they were able to complete it in 31 ± 7 min on day 20. The Total FLS score was 164 ± 48 before the start of training, and 1107 ± 112 on day 20. The average scores of the students closely approached the Proficiency Level for the FLS tasks of peg transfer, loop ligation and extracorporeal ligation (103→228, 61→137, 0→259). The change over time in the average of the increase in Total FLS Score (difference from the first time and each week's score) improved significantly in four weeks (P < 0.01). Conclusions: Origami crane training improved the medical students' FLS scores. We thought that origami crane training mainly enhanced hand-eye coordination and bi-hand coordination.

Prevalence and organ tropism of crane-associated adenovirus 1 in cranes overwintering on the Izumi plain, Japan.

Crane-associated adenovirus 1 (CrAdV-1) is a proposed novel virus in the genus Aviadenovirus, first detected in faecal samples from hooded cranes (a vulnerable crane species) on the Izumi plain, a major overwintering site for migratory cranes in Japan. CrAdV-1 was genetically characterized in that study; however, its virological characteristics remain largely unclear. To investigate the prevalence and organ tropism of CrAdV-1, we collected swab and organ samples from dead or debilitated cranes on the Izumi plain. CrAdV-1 gene was detected in 47% (45/95) of tested cranes, comprising mainly hooded cranes but also white-naped and sandhill cranes. These results indicate that CrAdV-1 shedding is widespread among cranes overwintering on the Izumi plain. Phylogenetic analyses revealed that the 68 nucleotide sequences determined from the positive swabs formed a single cluster, suggesting phylogenetic differences between CrAdV-1 and other aviadenoviruses. CrAdV-1 prevalence showed a significant linear increase with time through the overwintering period (November to February), especially among juveniles. These findings indicate that CrAdV-1 spreads mainly by transmission between juveniles progressively through the overwintering period. The CrAdV-1 gene-positive rate was significantly higher in cloacal swabs than conjunctival or tracheal swabs. Copy numbers for the partial CrAdV-1 gene sequence were markedly high in the colon samples from three of the four cranes investigated for organ tropism. We also detected relatively high copy numbers in the cerebrum, trachea, lung and heart, suggesting that CrAdV-1 mainly targets these four organs and transmitted via the faecal-oral route and airborne transmission. These results contribute to further understanding of the virological characteristics of CrAdV-1.

Major threats and habitat use status of Demoiselle crane (Anthropoides virgo), in district Bannu, Pakistan / Principais ameaças e estado de uso de habitat de Demoiselle crane (Anthropoides virgo), no distrito de Bannu, Paquistão

Cranes are the large and attractive Creatures of nature with long necks, legs, and life-span. Adults of both sexes are the same with similar color patterns. Demoiselle cranes spend most of their lifespan on dry grasses. They are also found around the stream, rivers, shallow lakes, natural wetlands, and depressions. To evaluate the current status of habitat use and major threats a study was conducted in tehsil Domel district Bannu. Line transect method and water quality tests (temperature, PH, contamination of E-coli bacteria) were used. To determine the major threats questionnaire method was used. The whole data was analyzed by using SPSS 21 version. Based on the distribution four study sites were selected and four water samples from each study site were taken. Most sites were moderate to highly degraded except Kashoo and kurram river mixing point which was low degraded with livestock grazing and human activities. Water quality tests showed PH ranges from 7-9, temperature 6.5-8.5, and contamination of E-coli in all samples. The social survey revealed that hunting, habitat degradation, and pollution as major threats. Effective long-term conservation and management in the study area are needed to focus on the protection of disturbance-free habitat.

Resumo Guindastes são a grande e atraente criatura da natureza com um pescoço longo, pernas e vida útil. Adultos de ambos os sexos são os mesmos com padrões de cores semelhantes. Guindastes Demoiselle passam a maior parte da vida em gramíneas secas. Também se encontram ao redor do córrego, rios, lagos rasos, pântanos naturais e depressões. Para avaliar o estado atual do uso do hábitat e as principais ameaças, um estudo foi realizado no distrito de Tehsil Domel, em Bannu. Foram utilizados o método transect e testes de qualidade da água (temperatura, pH, contaminação da bactéria E. coli). Para determinar as principais ameaçasfoi utilizado o método de questionário. Todos os dados foram analisados por meio da versão SPSS 21. Com base na distribuição, foram selecionados quatro locais de estudo e quatro amostras de água de cada local de estudo. A maioria dos locais estava moderada a altamente degradada, exceto no ponto de encontro dos rios Kashoo e Kurram, que teve baixa degradação com pastagem de gado e atividades humanas. Os testes de qualidade da água mostraram variação de pH de 7-9, temperatura 6,5-8,5 e contaminação de E. coli em todas as amostras. A pesquisa do questionário revelou que a caça, a degradação do hábitat e a poluição são as principais ameaças. Efetiva conservação e gestão a longo prazo na área de estudo são necessárias para se concentrar na proteção de um hábitat livre de distúrbios.
