-Loss of chromosome 17p or mutation in the TP53 gene, which resides at this genetic locus, is a powerful prognostic marker and predictor of response to therapy in patients with CLL.

-A mutation in TP53 is present in < 10% of patients at presentation but rises to 30% of cases at relapse. This test
should be performed in all patients prior to the initiation of therapy.

-Rarely, CLL transforms to an aggressive high-grade lymphoma, called Richter’s transformation.

-Recently, a more potent type 2 anti-CD20 antibody, obinutuzumab, has become available and produces better responses in combination with chlorambucil than rituximab in patients with CLL.

-Fludarabine should be avoided in autoimmune hemolytic anemia as it aggravates anemia in ttt of CLL.

In HL:

-A normochromic, normocytic anaemia or lymphopenia is present, this is a poor prognostic factor.

-An eosinophilia or a neutrophilia may be present.

-Bulky disease (> 10 cm in a single node mass) is an adverse prognostic feature.

-LDH measurements showing raised levels are an adverse prognostic feature.

-ABVD chemotherapy can cause cardiac and pulmonary toxicity, due to doxorubicin and bleomycin, respectively.

-The incidence of infertility and secondary myelodysplasia/AML is low with the above regimen.

-Brentuximab vedotin is an antibody–drug conjugate directed against CD30 on the Reed–Sternberg cell surface. Can produce good responses in patients who have failed, or are not suitable for, an autologous transplant and can be a ‘bridge’ to an allogeneic transplant.

-Reed-Sternberg cell is the hallmark of Hodgkin’s disease. Rarely, found in:

1-Infectious mononucleosis,
2-Recurrent Burkitt’s lymphoma and
3-CLL.

-High alkaline phosphatase (biliary obstruction) indicates involvement of lymph nodes in porta hepatis.

Side effects include restlessness, confusion, depression, skin rashes, edema, nausea, constipation, anorexia, postural hypotension, and disturbances of cardiac rhythm.

#Medicine

-The most common early side effects of levodopa are nausea, vomiting, and hypotension, but cardiac arrhythmias may also occur.

#Medicine

-Levodopa therapy is contraindicated in patients with psychotic illness or narrow-angle glaucoma.

-It should not be given to patients taking monoamine oxidase A inhibitors or within 2 weeks of their withdrawal, because hypertensive crises may result.

#Medicine

-Diarrhea is sometimes troublesome.
-Because rare cases of fulminant hepatic failure have followed its use, tolcapone should be avoided in patients with preexisting liver disease.

Some points in Angiofibroma:

-CT scan of the head with contrast enhancement is now the investigation of choice In angiofibroma.

-The most common presentation of angiofibroma is profuse, recurrent and spontaneous epistaxis.

-Most common origin of Angiofibroma is posterior part of nasal cavity close to the superior margin of sphenopalatine foramen.

-Antral sign or Holman-Miller is the anterior bowing of the posterior wall of maxillary sinus and is pathognomic of angiofibroma.

-Surgical excision is the treatment of choice.

-Recurrence of juvenile angiofibroma is not uncommon and has been reported in up to 35%.

-Nasal obstruction is the commonest symptom in Adenoid.

In Nasopharyngeal Carcinoma:

-Commonest site of origin of NC in the nasopharynx is the fossa of Rosenmüller.

-Most common involved cranial nerve is VIth "Abducent" which is the first to be involved.

-Trotter’s triad:
1)Conductive deafness (eustachian tube blockage)
2)Ipsilateral temporoparietal neuralgia (involvement of CN V)
3)Ipsilateral palatal paralysis (CN X).

-The most common presentation in Ca Nx is Cervical lymphadenopathy (60–90%), then hearing loss and nasal obstruction.

-High-resolution, contrast-enhanced CT of neck and nasopharynx is the study of choice. "CECT"

-Radiotherapy is the treatment of choice for nasopharyngeal cancer.
