I now have all the information needed. Here is the structured content based on the dissertation:

Objective

The study aimed to compare the ease of laryngoscopy and nasotracheal intubation using the McGrath Mac videolaryngoscope versus the McIntosh (Macintosh) laryngoscope in patients with panfacial fractures posted for oral and maxillofacial surgeries under general anaesthesia. Specifically, the study sought to compare the percentage of glottic opening (POGO score) and Cormack & Lehane grading achieved with each device, assess the mean time taken for laryngoscopy and nasotracheal intubation, record the number of intubation attempts, frequency of use of Magill's forceps, and requirement of optimal external laryngeal manipulation (OELM), and evaluate the hemodynamic response - including heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure - to laryngoscopy and intubation in both groups.

Result

Nasotracheal intubation was successfully achieved on the first attempt in all 40 patients across both groups. The POGO score was significantly superior in the McGrath group compared to the McIntosh group (98.25 ± 2.944% vs. 42.25 ± 14.91%; p<0.001). Cormack & Lehane grade 1 view was obtained in all 20 patients in the McGrath group, while grade 2 and grade 3 views predominated in the McIntosh group (80% grade 2, 20% grade 3; p<0.001). Time taken for laryngoscopy was significantly shorter in the McGrath group (10.50 ± 1.88 s vs. 15.65 ± 2.52 s; p<0.001), as was the time taken for intubation (14.10 ± 3.26 s vs. 21.95 ± 4.72 s; p<0.001), and the total intubation time (24.60 ± 4.11 s vs. 37.45 ± 6.12 s; p<0.001). Optimal external laryngeal manipulation was required in 50% of McGrath cases versus 95% of McIntosh cases (p<0.001). Magill's forceps were not required in any of the 20 McGrath group patients, whereas 19 out of 20 (95%) McIntosh group patients required its use (p<0.001). No statistically significant difference was found in hemodynamic parameters - heart rate, systolic blood pressure, diastolic blood pressure, and mean arterial pressure - between the two groups at any recorded time point (p>0.05 for all).

Conclusion

The McGrath Mac videolaryngoscope significantly facilitates nasotracheal intubation in patients with panfacial fractures undergoing oral and maxillofacial surgeries, offering markedly superior glottic exposure (as reflected by POGO score and Cormack & Lehane grading), shorter laryngoscopy and intubation times, and greatly reduced need for optimization manoeuvres including OELM and Magill's forceps. Notably, the use of Magill's forceps was completely avoided in the McGrath group, demonstrating the device's practical advantage in this challenging patient population. However, no statistically significant difference was observed in the hemodynamic response to laryngoscopy and intubation between the two groups, which may be attributed to the relatively small sample size. Overall, the McGrath Mac videolaryngoscope is superior to the McIntosh laryngoscope for nasotracheal intubation in panfacial fracture patients.

Here is a detailed clinical case scenario for an 18-year-old girl with primary amenorrhea due to Turner syndrome:

Case Scenario: Primary Amenorrhea - Turner Syndrome

Patient Identification

Name: Miss R.K. Age: 18 years Sex: Female Occupation: College student Referred by: General Practitioner

Chief Complaint

"I have never had my periods" - presenting with primary amenorrhea since expected age of menarche.

History of Present Illness

An 18-year-old girl presents to the gynecology OPD with her mother, with a complaint of never having had menstrual periods. Her mother noticed that she has always been shorter than her classmates. At age 14-15, when her friends began developing breasts and having periods, she showed no such changes. She has no breast development, no pubic or axillary hair, and no episodes of cyclic abdominal pain suggestive of cryptomenorrhea. There is no history of headache, visual disturbance, anosmia, or galactorrhea. No history of chronic illness, medications, or radiation exposure. She has no history of lymphedema at birth as recalled by the mother, but a "puffiness" of the neck was noted in childhood.

Past History

No significant childhood illnesses
No prior surgeries
No known drug allergies
Immunization history: up to date

Family History

No family history of similar condition
No history of consanguineous marriage

Menstrual History

Menarche: Never attained (Primary amenorrhea)
No history of cyclical pain

General Physical Examination

Parameter	Finding
Height	142 cm (well below 3rd percentile)
Weight	46 kg
BMI	22.8 kg/m²
Blood pressure	148/94 mmHg (elevated - coarctation screening)
Pulse	82 bpm, regular
Build	Short stature, stocky build

Dysmorphic features noted:

Low posterior hairline
Webbing of the neck (pterygium colli)
Shield-shaped (broad) chest with widely spaced nipples
Cubitus valgus (increased carrying angle of the arms bilaterally)
Multiple pigmented nevi over the trunk
High-arched palate
Short fourth metacarpals on hand examination
No peripheral lymphedema at present

Secondary Sexual Characteristics

Breast development: Absent (Tanner Stage 1)
Pubic hair: Absent (Tanner Stage 1)
Axillary hair: Absent
External genitalia: Normal female, infantile appearance
Uterus: Small, hypoplastic on per-abdominal examination

Clinical features and karyotypes of Turner syndrome - Robbins & Kumar Basic Pathology

Systemic Examination

Cardiovascular: Systolic murmur heard at the left sternal border and interscapular area; radio-femoral delay present (suggestive of coarctation of aorta)
Respiratory: Clear to auscultation
Abdomen: No organomegaly; no palpable pelvic mass
CNS: Alert, oriented; normal intelligence; mild difficulty with visuospatial tasks noted on informal testing

Investigations Ordered

Hormonal Profile

Test	Result	Normal
Serum FSH	78 mIU/mL	3-10 mIU/mL (follicular)
Serum LH	42 mIU/mL	2-15 mIU/mL
Serum Estradiol (E2)	<10 pg/mL	20-350 pg/mL
Serum Prolactin	12 ng/mL	Normal
TSH	6.8 mIU/L	Elevated (subclinical hypothyroidism)
Free T4	Low-normal
Anti-TPO antibodies	Positive	Suggestive of autoimmune thyroiditis

Interpretation: Elevated FSH and LH with low estradiol = Hypergonadotropic hypogonadism - consistent with primary gonadal failure.

Karyotype

Result: 45,X - Confirms Turner syndrome
No Y chromosome sequences detected

Imaging

Pelvic ultrasound: Uterus small (4.5 × 1.5 cm); bilateral ovaries replaced by fibrous streak gonads (no follicles identified)
Echocardiography: Coarctation of aorta confirmed; bicuspid aortic valve noted
Renal ultrasound: Horseshoe kidney identified
Bone age X-ray: Delayed bone age (~14 years)
DEXA scan: Low bone mineral density (Z-score: -2.1) - osteopenia

Other Investigations

Fasting blood sugar: Normal
Hearing test: Mild bilateral sensorineural hearing loss
Liver function, renal function: Normal

Diagnosis

Primary (Confirmed) Diagnosis:

Turner Syndrome (45,X karyotype) presenting as Primary Amenorrhea with Hypergonadotropic Hypogonadism

Associated Findings:

Coarctation of aorta + bicuspid aortic valve
Horseshoe kidney
Autoimmune hypothyroidism (Hashimoto's thyroiditis)
Osteopenia
Mild bilateral sensorineural hearing loss

Pathophysiology (Summary)

In Turner syndrome (45,X), the ovaries initially develop normally in utero, but suffer accelerated atresia of follicles postnatally - leaving behind fibrotic streak gonads. These streak ovaries cannot produce estrogen or inhibin, so the pituitary is uninhibited and FSH/LH rise markedly (hypergonadotropic state). The result is:

No estrogen surge → no breast development, no endometrial proliferation
No positive feedback on LH → no ovulation, no progesterone → primary amenorrhea
No estrogen → poor bone mineralization → osteopenia

The somatic features (short stature, webbed neck, cubitus valgus, cardiac and renal anomalies) result from haploinsufficiency of genes on Xp that escape X-inactivation, particularly the SHOX gene (short stature homeobox gene).

Management Plan

1. Hormone Replacement Therapy (HRT) - Priority

Begin with low-dose estrogen (ethinyl estradiol 5-10 mcg/day orally or transdermal estradiol 0.5 mg/day) to induce puberty gradually
After 12-18 months or with breakthrough bleeding, add cyclic progestogen (medroxyprogesterone acetate 5-10 mg for 10-12 days/month) to protect the uterus
Continue HRT until the natural age of menopause (~50 years)

2. Cardiac Management

Refer to cardiology for surgical repair/intervention for coarctation of aorta
Echocardiography every 3-5 years; cardiac MRI for aortic surveillance
Blood pressure control

3. Thyroid Management

Start levothyroxine for subclinical hypothyroidism
Annual TSH monitoring

4. Bone Health

Calcium (1000-1300 mg/day) and Vitamin D (600-800 IU/day) supplementation
Repeat DEXA scan in 2 years

5. Renal Follow-up

Urological referral for horseshoe kidney
Annual blood pressure monitoring and renal function tests

6. Fertility Counseling

Naturally conceived pregnancy is nearly impossible due to streak ovaries
Oocyte donation with IVF is the main option for future pregnancy
Pre-pregnancy cardiac assessment is mandatory given aortic risk

7. Psychological Support

Counseling regarding diagnosis, body image, and fertility
Support groups for Turner syndrome

8. Hearing

Audiological follow-up; hearing aids if needed

Prognosis

With estrogen replacement therapy, secondary sexual characteristics will develop and menstrual cycles can be induced
Cardiovascular anomalies (especially coarctation of the aorta and aortic dissection) are the leading cause of premature mortality and require lifelong surveillance
Intelligence is usually normal; fertility is severely reduced but not impossible with assisted reproductive technology
Regular screening for diabetes, hypertension, and aortic enlargement is needed lifelong
