I try to be very thorough and very efficient, but
I do NOT do "quick" evaluations. My motto is to
"Do it right the first time!"
I also strongly believe that
"two heads are better than one" -- so
I try -- whenever possible -- to have
a nurse or a social worker or a mental health tech or a post-graduate medical/ psychiatric trainee with me for the initial evaluation of a patient --
even in the Emergency Room.

I also do more than that.
I evaluate and try to address each patient’s
ability to form and use concepts – as well as
simple issues of a
soft neurologic, nutritional, and endocrinologic
nature that frequently
contribute to a patient's presenting problems.

Two observational studies:
PART ONE –
Differentiation of Moods as a Reflection of
Ego Organization and Personality Style:
Listening Very, Very Closely as
Patients Answer Only Five Questions.
[neurotic/ normal,
borderline,
schizophrenic/ schizotypal]
As an integral part of every initial psychiatric
evaluation, this clinical approach quickly
elicits verbalized data on
a patient's ability -- or lack of ability --
to form and use concepts.
It also quickly provides data on what is
NOT schizophrenia and what is
NOT borderline personality disorder,
while quickly suggesting
probable neurotic conflicts and
likely neurologic/ endocrinologic issues.
PART TWO –
Erroneous Psychiatric Self-Diagnosis:
Non-Psychiatric Patients that
Present at a Psychiatrist’s Office.
APPENDIX – Elucidation of Useful
Additional Clinical Data.

the most common -- correlating highly with

***** Generally, the neurologic component is primary,
with an endocrinologic component appearing later & making the situation worse. Being malnourished or
drug-addicted certainly does not help. Having additional psychiatric issues certainly does not help. Many of these patients do respond quickly to treatment once the

“Listening Closely” is about trying to make
interesting and significant a lot of clinical
information that has been there all the time –
waiting to be gathered –but frequently
not perceived, conceptualized, and appreciated.
"Listening Closely" is about finally grasping
what the patient has been saying --
or trying to say --
or trying to find the words to say --
all along.

*****
[Many recent investigators appear to be
relatively inexperienced in using pentoxifylline --
in that they do not seem to understand that
pentoxifylline does not work immediately.
It is NOT a TNF-alpha "blocker," for example, but is
a TNF-alpha "production inhibitor" --
working at the RNA level.
The time to begin prescribing
pentoxifylline (with food & fluid) for a patient is
NOT upon an admission to hospital, but, rather,
several weeks before such admission might be needed.]
Important New Article -- February 2022:
Feret W, Nalewajska M, Wojczyński Ł, Witkiewicz W, Kłos P, Dziedziejko V, Pawlik A. “Pentoxifylline as a Potential Adjuvant Therapy for COVID-19: Impeding the Burden of the Cytokine Storm [and of Fibrotic Clots].” J Clin Med. 2021 Nov 15;10(22):5305; https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8617922/ ;
“… Pentoxifylline (PTX) is a drug that exhibits broad-spectrum anti-inflammatory and immunomodulatory effects through mechanisms involving the adenosine A2A receptor (A2AR), in parallel with rheological effects. Previous studies have shown that PTX has anti-inflammatory effects and, therefore, may be beneficial in countering the cytokine storm caused by COVID-19. This drug has also been shown to reduce lung fibrosis in patients with COVID-19, as well as to prevent thromboembolic events. Therefore, PTX may exert potential benefits in treating the symptoms of SARS-CoV-2 as well as its complications.” [bolding added]
[in early 2022, the role of fibrin clots in COVID-19 deaths became more appreciated]
Brubaker LS, Saini A, Nguyen TC, Martinez-Vargas M, Lam FW, Yao Q, Loor MM, Rosengart TK, Cruz MA. “Aberrant Fibrin Clot Structure Visualized Ex Vivo in Critically Ill Patients With Severe Acute Respiratory Syndrome Coronavirus 2 Infection.” Crit Care Med. 2022 Feb 15; https://pubmed.ncbi.nlm.nih.gov/35170535/ ; “… Blood was collected from 36 patients including 26 ICU patients with COVID-19 and 10 ICU patients with sepsis but without COVID-19 at a median of 11 days after ICU admission (interquartile range, 3-16). The cohorts were similar in age, gender, body mass index, comorbidities, Sequential Organ Failure Assessment (SOFA) score, and mortality. More patients with COVID-19 (100% vs 70% ...) required anticoagulation. Ex vivo fibrin clots formed from patients with COVID-19 appeared to be denser and to have smaller pores than those from patients with sepsis but without COVID-19 …. We found aberrant fibrin clot structure and function in critically ill patients with COVID-19. These findings may contribute to the poor outcomes observed in COVID-19 patients with widespread fibrin deposition.” bolding added]

Pentoxifylline:
A Versatile Off-Patent Medication
Best Not Overlooked
Some Published Medical Thoughts about
COVID-19 & Pentoxifylline
(a phosphodiesterase 4 inhibitor )
(a production inhibitor of
TNF-alpha, IL-6, & IL-2R --
all of which inflammatory cytokines are
higher in COVID-19 infection)
*****
[Many recent investigators appear to be
relatively inexperienced in using pentoxifylline --
in that they do not seem to understand that
pentoxifylline does not work immediately.
It is NOT a TNF-alpha "blocker," for example, but is
a TNF-alpha "production inhibitor" --
working at the RNA level.
The time to begin prescribing
pentoxifylline (with food & fluid) for a patient is
NOT upon an admission to hospital, but, rather,
several weeks before such admission might be needed.]

“… Pentoxifylline (PTX) is a drug that exhibits broad-spectrum anti-inflammatory and immunomodulatory effects through mechanisms involving the adenosine A2A receptor (A2AR), in parallel with rheological effects. Previous studies have shown that PTX has anti-inflammatory effects and, therefore, may be beneficial in countering the cytokine storm caused by COVID-19. This drug has also been shown to reduce lung fibrosis in patients with COVID-19, as well as to prevent thromboembolic events. Therefore, PTX may exert potential benefits in treating the symptoms of SARS-CoV-2 as well as its complications.” [bolding added]
[in early 2022, the role of fibrin clots in COVID-19 deaths became more appreciated]
Brubaker LS, Saini A, Nguyen TC, Martinez-Vargas M, Lam FW, Yao Q, Loor MM, Rosengart TK, Cruz MA. “Aberrant Fibrin Clot Structure Visualized Ex Vivo in Critically Ill Patients With Severe Acute Respiratory Syndrome Coronavirus 2 Infection.” Crit Care Med. 2022 Feb 15; https://pubmed.ncbi.nlm.nih.gov/35170535/ ; “… Blood was collected from 36 patients including 26 ICU patients with COVID-19 and 10 ICU patients with sepsis but without COVID-19 at a median of 11 days after ICU admission (interquartile range, 3-16). The cohorts were similar in age, gender, body mass index, comorbidities, Sequential Organ Failure Assessment (SOFA) score, and mortality. More patients with COVID-19 (100% vs 70% ...) required anticoagulation. Ex vivo fibrin clots formed from patients with COVID-19 appeared to be denser and to have smaller pores than those from patients with sepsis but without COVID-19 …. We found aberrant fibrin clot structure and function in critically ill patients with COVID-19. These findings may contribute to the poor outcomes observed in COVID-19 patients with widespread fibrin deposition.” bolding added]
